Title:Accurate and Efficient Computation of Electromagnetic Fields and Waves over Unbounded Regions in 3D
Abstract:The proposed project will rectify the current bottleneck in the simulation of 3D magnetic fields around high-current pulsed power devices. In the existing software, fields in the air are approximated by an artificial magnetic diffusion equation, which is both computationally expensive and nonphysical. The proposed solution avoids any nonphysical quantities and relies on exact conditions for the quasi-static component of the field and on very accurate absorbing boundary conditions for the wave component, developed and validated by our consultant Prof. S. Tsynkov. Specific and verifiable advantages of our approach are: (i) High accuracy. The treatment of the unbounded outer region relies on a precise physical and analytical description of the exterior field and interface conditions. (ii) Dramatically reduced computational complexity: no grid is needed in the exterior region. (iii) Ease of coupling with the existing simulator, such as Mach3. (iv) Generality and efficiency for multiple simulations. Phase I includes innovative R&D of modeling 3D fields, with both quasi-static and wave effects of Maxwell’s equations included. Solutions to test problems will be calculated and compared with analytical and accurate numerical benchmarks to fully demonstrate the validity of the proposed approach. In Phase II, the innovative 3D algorithms will be implemented as software tools, coupled with the Air Force 3D-MHD codes and extended to problems with complex geometries of interest to Air Force .

Title:Three-Dimensional Fast-Multipole Solvers for Magnetic Fields for Use in High-Current Pulsed Power Application Systems
Abstract:This proposal presents an innovative concept and a novel approach to achieve topic solution. The innovative concept is known as the Next Generation Troop Seat (NGTS). It is a semi-rigid foam and fabric seat which achieves its capabilities through the integration of a Dynamic Structural Beam (DSB). In the mishap environment the patented and proven DSB provides a higher strength to weight ratio than currently employed conventional seat components. It also provides the energy attenuation that makes the seat “crashworthy”. In limited evaluations DSB based crashworthy troop seats have demonstrated to be stronger, lighter and cheaper than existing fielded and proposed systems. The novel approach is to reduce overall program risk by developing three new variants of the NGTS. Each of these variants will specifically address, at the lightest weight possible, the three established performance criterions. The recent, over the last decade or so, implementation of crashworthy troop seats has identified that weight is the critical issue in their employment. By providing three variants the implementer will be able to choose the best solution for their application and not be limited by the weight constraint of a single solution. BENEFIT: The Multi-Variant/Capability Next Generation Troop Seat (M- V/C NGTS) is a lightweight crashworthy troop seat that offers the US DoD several options for its rotary-wing aircraft. Each variant addresses a critical segment of the fleet while balancing the compromises of weight and performance. As a result, implementation of the M-V/C NGTS will enhance troop safety across the entire aircraft fleet.

Title:3D Magnetic Field Modeling
Abstract:We propose to employ a novel Boundary Element Method (BEM) numerical technique to develop a parallel computer code that will allow simultaneous solution, in three dimensions (3-D), of the vacuum magnetic vector potential and magnetic field structure for complex geometries. The primary advantages of the chosen approach are the reduction of the dimensionality of the problem from three (volume) to two (surface) dimensions, and the avoidance of wasteful computation of fields and potentials away from conductor surfaces of interest. Furthermore, artificial external problem domain boundaries with generally unknown boundary conditions are avoided. The resulting code can either be employed stand-alone, for design purposes, or in combination with existing magneto-hydrodynamic (MHD) or static magnetic diffusion codes based on finite-difference, finite-volume, finite- element, or even time-domain BEM techniques.

Title:Innovative Research for Crashworthy Stowable Troop Seating for Helicopters
Abstract:F3 Engineering (F3) proposes to demonstrate the feasibility of developing and producing an innovative concept for crashworthy, lightweight, and rapidly stowable/removable helicopter troop seats with crash protection equivalent to the current flight crew seats. F3 will utilize our experience in development of energy management systems using Magnetorheological Fluid Technology (MRFT). F3 proposes a Magnetorheological Advanced Energy Absorber concept (MAEA) that integrates with current seat structures replacing traditional energy absorbers. The MAEA will include electronically controlled shock absorbing hardware that, in a crash, will absorb the energy to reduce the risk personnel injury. This system will determine the gross weight of the system, including the seat structure and occupant and will control the seat response in a crash event. The proposed system is modular, where shock attenuation will be located as needed, regardless of the configuration of the troop seat(s). Phase I efforts will include the evaluation of historical crash test data on seats and seat occupants, mathematical modeling and simulation of the proposed MAEA system and the development of feasible concepts worthy of further investigation and empirical testing.

Title:Impact Dispersal System for Crashworthy Stowable Troop Seating for Helicopters
Abstract:The seats used to carry troops in large Special Operation or Search & Rescue helicopters only provide limited protection in the event of a crash. These troop seats do not adequately attenuate the energy during a crash pulse or restrain the crewmember during impact and roll- over events. The crashworthy features of helicopter seats today incorporate some type of a mechanical device in order to absorb the energy from an impact. These energy absorbers use a pre-defined load-displacement profile in their design, which can be overly sensitive and not compatible with the wide range of troop and equipment weights. The Impact Dispersal System is a new invention that takes a different approach to reducing impact force by dispersing the force away from the point of impact. The system explodes the dispersion at the point of impact and then systematically shuts down according to the amount of force produced by the impact. Our goal is to incorporate this system into an existing helicopter troop seat in order to enhance crash protection. The lightweight and rapidly stowable/removable features of the existing troop seat will be kept with the incorporation of the Impact Dispersal System.

Title:Mobile Aircrew Crashworthy Seating Systems for Helicopters
Abstract:This Phase I program would examine the feasibility of developing an innovative mobile aircrew crashworthy seating prototype that allows the cabin crewmembers the freedom to perform the majority of their airborne tasks but also allows for easy and rapid repositioning or stowing of the seat to accommodate cargo/troop ingress/egress, hoist operations, etc. The seating system will provide adequate crew protection and restraint during a crash pulse at least equivalent to the flight crew seats. Also we will develop and evaluate differnet EA and restraint technology concepts that have been suggested and developed to provide the best possible crash protection to the entire aircrew population. We will demonstrate design success via computer modeling/simulation and prototype testing. This SBIR Phase I will yield a quantitative set of seat design guidelines and models that can be implemented to military helicopter and civil rotorcraft. Later Phase II studies could include more engineering development and prototype seat tests.

Title:Mobile Aircrew Crashworthy Seating Systems for Helicopters
Abstract:Infoscitex proposes an innovative seating system for helicopter mobile aircrew, which is designed based upon a number of creative ideas. (a) A turning table, as the base of the entire structure, allows the seat to turn around by any degree. (b) A retractable sliding track, mounted on the turning table, allows the seat to move in any direction by as far as 4 ft. (c) A robot seat frame, using four pneumatic control rods to control seat frame motion, provides adaptable support and optimal energy attenuation to each individual occupant. (d) An extensible five-point harness belt allows the occupant to rapidly transition from seated to half-standing and to full standing position and provides security to aircrew while reaching out of the aircraft to perform mission duties. (e) A seat cushion with optimized configuration and material provides improved seating comfort. The seat is stowable, and its weight is minimized for its sophisticated structure. In phase I, we will further develop our proposed concept, perform conceptual design, complete and refine the system architecture, and prove our preliminary concept using virtual testing. In phase II, the concept will be fully tested and proved, and a prototype will be constructed, analyzed, tested, and evaluated.

Title:Multifunctional Materials & Component Technologies for Managing Micro-Climate Domain in the Integrated Aircrew Ensemble (IAE) Architecture
Abstract:EY agrees with Air Force that integration of technologies on archaic aircrew ensemble architecture of 1960’s doesn’t allow leveraging the full potential of the component functionalities in the resulting “Christmas Tree Architecture”. EY proposes an IAE architecture where specific functionalities are designated into two main domains. Micro-Climate Domain – Layers of ensemble that are next to the skin and Macro- Climate Domain – where external interaction is fundamentally more critical. Micro-Climate focuses on user physiological and thermal balance issues, Macro-Climate Domain would focus on ballistics and survival related issues. One magic material solution for aircrew ensemble that has all the desired functionalities and work across multiple platforms does not exist. EY proposes a managed risk approach of developing, adapting and integrating multifunctional materials & components (TRL – 6 and above) to develop an IAE ensemble that helps manage the Aircrew’s Micro-Climate. Engineered Yarns (EY) proposes to develop and demonstrate the following low risk multifunctional technologies for IAE. •Bi-Layer no Melt No Drip fabrics for Fire Protection, Thermal and Physiological management •Controlled Air Permeable Electro-Spun Web for CB Protection, Thermal and Physiological management •Hydrogel Based Smart Closure System – User comfort and thermal balance •High Bulk Low Weight Fabrics for Reduced Layers

Title:Novel NanoStructured Self-Assembled Fabric Coatings for Future Aircrew Life Support Equipment
Abstract:NanoSonic proposes to develop an innovative fabric coating for future aircrew life support equipment that is flame-resistant, antimicrobial, breathable, durable, comfortable, and provides water-immersion protection superior to current legacy aircrew life support equipment using Electrostatic Self-Assembly (ESA) processing. ESA is an environmentally-friendly, low-cost fabrication process that can be utilized to fabricate countless types of functional materials and coatings on a variety of substrates and fabrics. The proposed coatings can be applied to new or existing fabrics. Because the volume percentages of functional nanoclusters needed for ESA is as low as 0.02% volume percent, the coatings are extremely low-weight for fabrics to which they are applied. Therefore, the proposed self-assembled fabric coatings would enable aircrew to comfortably don and transport the necessary life support equipment during operations. Because the nanostructured coating is non-obtrusive to the fabric to which it is applied, the fabric would remain nearly as breathable after the coating is applied as it was before, which would allow for adequate ventilation for the aircrew personnel. Improved performance and reduced weight of the proposed self-assembled protective suit would ensure that aircrew’s performance and comfort would not be burdened by wearing the protective ensemble, thus increasing effectiveness and improving survivability.

Title:SiGe Digital Imaging Sensors for Night Vision Goggles
Abstract:In this project, Agiltron and RTI International propose a SiGe digital imaging sensor to replace the image intensifier tube in night vision goggles. The SiGe digitial imaging sensor will satisfy all modern warfighter requirements, including reductions in size, weight, power consumption, and cost; digitization of the output image; spectral coverage of both the visible and shortwave infrared (SWIR) bands; higher sensitivity; and higher resolution. The SiGe digital imaging sensor consists of a Si-based CMOS imaging sensor with monolithically integrated SiGe photodiodes to extend the cutoff wavelength deep into the SWIR. By introducing SWIR capability to the mature CMOS imaging technology, we uniquely exploit the advantages each technology offers to realize a digital imaging sensor for night vision applications with unprecedented functionality and low cost.

Title:Solid State Night Vision Sensor
Abstract:Trex Enterprises Corporation (Trex) proposes to develop a broadband (400nm ¡V 1600 nm) CMOS-based focal plane array (FPA) that provides video imaging capability in daylight conditions, and also in moonlight and moonless night conditions. The FPA will incorporate the Trex Photoconductor on Active Pixel (POAP) FPA technology. In the past year, Trex has demonstrated broadband visible-SWIR FPA imaging capability using a hybrid amorphous silicon/microcrystalline germanium (a-Si:H/ƒÝc-Ge) photodiode (400 nm ¡V 1600 nm VIS/SWIR spectrum) coated on a CMOS readout integrated circuit (ROIC). The proposed Phase I effort will involve the design, fabrication and demonstration of an improved a-Si:H/ƒÝc-Ge photodiode on a novel CMOS ROIC that has been previously developed for commercial cell phone applications. The design will be based on test data from the on-going development of the a-Si:H/ƒÝc-Ge photodiode technology. We will demonstrate the FPA imaging capability in illumination conditions that are consistent with night vision applications. We will work closely with the Air Force to define the design specifications of the proposed FPA. The proposed Phase II effort will involve the fabrication, testing/optimization and delivery of four prototype VIS/SWIR FPAs to the government. We are presently investigating multiple avenues of potential Phase III commercialization of the proposed technology.

Title:Solid State Night Vision Sensor
Abstract:In Phase I, a 1280 x 1024 element InGaAs Solid State LLLTV (Low Light Level Television) Imager with 0.4- to 1.7-micron sensitivity will be developed to achieve visible (VIS) and short-wavelength infrared (SWIR) spectral range that is well matched to the nighttime sky irradiance. The extended spectral response (including the 1064 nm and 1550 nm) laser lines, allows the ability of the Solid State LLLTV imager to serve multiple purposes, including enhanced situational awareness. A high pixel density is achieved by directly bonding the detectors to readout integrated circuits (ROICs) manufactured using conventional CMOS technology. Whereas, typically detector arrays are bump bonded to ROICs, in the Phase I program, the InGaAs detector array and the Si ROIC will be bonded into a robust, monolithic structure using ‘via-less’, ‘face-to-face’, room temperature, 3D heterogeneous InGaAs die-to-Si wafer bond. Increase visible response is achieved in the InGaAs detector, but removing the Inp substrate and back-illuminating the array. In Phase I, the LLLTV’s components will be characterized first individually, and then together, and the technology’s improved image quality, reduced pixel size, and low power requirements for NVGs will be established so that in Phase II, prototypes can be delivered to AFRL for evaluation.

Title:Non Focal Plane Laser Protection Technology Based on Combinatorial Optical Limiting Approaches
Abstract:This Small Business Innovation Research Phase I proposal offers to develop a solid, non-focal plane based laser protection technology that will meet the requirements of fast response time, high transparency under normal illumination conditions, and increased broadband (400 to 1400 nm) spectral response for the protection of eyes and sensors from laser beams. A novel approach to composite optical power limiters (OPLs) based on multi-component non-linear optical (NLO) materials, namely carbon nanotubes and organic NLO chromophores, that will be blended together in a common matrix is proposed. A proprietary hyperbranched polymer that forms excellent optical quality films and non-yellowing, scratch resistant coatings will be used as the host material. Oxazogen’s solid state OPL technology represents a paradigm shift from currently available technologies and has the potential to provide the best overall laser protection. Current laser protection technologies do not provide an adequate solution to the simultaneous challenges of fast response time, low energy threshold over broadband radiation. Salient features of Oxazogen’s approach include an easy to process solid state material, the ability to be coated on a variety of optical substrate, and the fact that it can be used as an independent filter, requiring no reworking of current system configurations.

Title:Alternating Nanostructured Multilayer Optical Limiter
Abstract:To address the Air Force need for an optical limiter without a focusing lens to provide sufficient attenuation to prevent eye damage at incident radiation levels that would otherwise cause retinal injury, Physical Optics Corporation (POC) proposes to develop a new nonfocal plane Alternating Nanostructured Multilayer Optical Limiter (ANMOL), based on nonlinear periodic optical structures consisting of alternating layers of interval films with the same linear indices of refraction and opposite Kerr nonlinearities that enhance optical reflection to meet the high optical density requirement for non-facial plane laser eye protection. The innovative design of the multilayer film structures and use of nanostructured materials for fabrication will enable the ANMOL to perform frequency-agile laser eye protection at an optical density >4 through the near-infrared and visible spectrum (400-1400 nm) without the use of a focal plane. The ground state luminous transmittance in the visible spectrum will achieve 50%. The response time of the ANMOL will be below 2 ns. In Phase I POC will demonstrate the feasibility of ANMOL by computer modeling and testing a proof-of-principle prototype. In Phase II POC plans to develop an engineering prototype for laser eye protection through testing in a laboratory environment.

Title:Optical Limiters Without Focal Planes
Abstract:The overall goal of the program is to develop an optical limiter without a focusing lens that provides sufficient attenuation to prevent eye damage at incident radiation levels that would otherwise cause retinal injury. High transmission (>15%), high on-state optical density (>4) and rapid response (nsec) are desired. Several new laser eye protection device designs are proposed and will be examined in detail in the course of the Phase I program. Each device exploits a fundamentally different optical limiting mechanism in organic and polymeric materials, namely nonlinear absorption, nonlinear refraction and nonlinear scattering. State-of-the- art nonlinear optical (NLO) polymers will be used as the optical limiting materials in coupled cavity, photonic band gap, and nonlinear photonic crystal device structures. Early in Phase I, potential candidate devices will be down-selected based on criteria such as limiting threshold, response time, low intensity transmission, and dynamic range among other key factors. Unique coupled cavity designs exploit intracavity enhancement without significantly limiting bandwidth. Photonic band gap devices will attempt to exploit recently developed NLO polymers with exceptional nonlinear index changes. Nonlinear scattering devices will take advantage of newly developed techniques for polymer melt infiltration into photonic crystal structures.

Title:Optical Limiters Without Focal Planes
Abstract:We propose to develop light weight optical limiters without focusing lens that provides sufficient attenuation, optical limiting >=104, at incident radiation levels that would otherwise cause retinal injury. At the same time it maintains a ground state transmittance of 50%. These optical limiters will have a tremendous improvement on the safety of the solders and the commercial laser operators. In the proposed optical limiter without focal plane the high energy beam is diffused on the substrate plan and off the optical axis of the limiter due to destructive interference of the high energy beam induced by optical nonlinear material. As the incident radiation increases by one fold the nonlinear phase increases by multiple folds, nonlinear effect, as result less and less radiation is transmitted and more radiation is diffused in the substrate. The phase nonlinearity is orders of magnitude higher than the nonlinear absorption from e.g. reverse saturable absorbers (RSA’s) or though two photon absorption (2PA). Furthermore, the nonlinear phase shift is highly sensitive and has a nonlinear energy threshold that is order of magnitude lower than the nonlinear absorption threshold. Therefore the nonlinear phase interferometers effect, which occurs at low optical radiation level below retinal damage threshold, enables the design of optical limiters without focal plan, a clever design allows the optical limiter to be light weight on thin substrate. This is the first time to our knowledge such an optical limiter is proposed. This proposed optical limiter without focal plane will be of immediate use for as a passive filter for visible in IR spectrum optical sensors protection and as a goggles in any field that employs high energy laser eye protection, e.g. medical laser surgery, dental laser surgery, laser operators, lab technicians,

Title:Low-Power Direct-View Flexible Displays
Abstract:The goal of this U.S. Army SBIR program is to develop non-glass, ejection-safe digital displays to replace printed paper maps and checklists on pilots’ knees in tactical cockpits, and to also enable large displays that can be rolled up for stowage. In this proposal UDC and L3 Displays will develop low power consumption flexible full color video rate phosphorescent OLED displays that can be rolled around a cylinder for stowage. If successful, in Phase II the team will deliver four breadboard subsystems with 6” diagonal 480 x 480 pixel full color displays wrapped around a 2.5” diameter cylinder containing power supplies, and wireless communication electronics. The resultant display device will show full motion video and have wireless connectivity enabled by the electronics contained within the cylindrical housing. To our knowledge, this display represents the world’s largest and highest resolution OLED display fabricated on a metal substrate, and also the first designed to wrap around a cylinder for stowage. At the end of Phase I we will deliver a design study of our proposed Phase II display systems, and a mock-up of this Phase II deliverable.

Title:High-Resolution Wide-Field Night Vision Goggle
Abstract:Night vision has been a key enabling technology for the past 30 years that has allowed US pilots to “own the night”. In many engagements, our dominance of the nighttime environment was the decisive factor in victory. One of the big disadvantages of night vision systems is that they have not provided pilots with good peripheral vision, since most have a total field of view (TFOV) of only 40 degrees. The PNVG addresses the need for wide field of view and has received very positive reviews from aviators. In the 15 years since the PNVG was designed, tremendous advances have been made both in the area of microdisplay technology and in the area of high-resolution digital night vision sensors. Our high resolution night vision system (HRNVS) will have improved resolution, 2) improved weight and center of gravity, 3) reduced peripheral obscurations compared to PNVG. Our decades of experience in designing head mounted displays convinced us that these three factors will make a compelling case for a new panoramic night vision goggle system. In addition, we have designed a novel helmet interface kit and mount which we believe will be lighter and easier to use than the current “banana clip” system.

Title:Head-Lock Mount for Advanced Night Vision Goggle (NVG)
Abstract:Diffraction LTD proposes to develop a novel occipital head-lock system to support advanced night vision goggles (NVG) used by Air Force personnel not wearing typical aviation or combat helmet. Phase I efforts will demonstrate the feasibility of a lightweight, direct head mount that maintains optimal NVG performance in the absence of a helmet, minimizes user fatigue, and reduces the risk of injury. Designs will focus on derivations of an occipital head-lock system with fine adjustment that ensures stable alignment of NVGs under variable conditions, is compatible with existing communication systems and specialty head- gear, i.e. chem.-bio masks/hoods, etc, and demonstrates reduced potential for torque-jolt. Using finite element analysis and human biodynamics software we will evaluate newer, lightweight materials to be used in place of bulky metal components, optimize hinge points and brackets to reduce weight and improve stiffness, and adjust designs to provide optimal fit and comfort across a broad range of users. This device will provide a superior mechanism for employing NVGs without helmets in both static and dynamic work settings, while minimizing stress and fatigue on a user’s head and neck.

Title:Head Mounting Device for Advanced Night Vision Goggle (NVG) Systems
Abstract:The current flight helmet provides impact protection while enabling communications and serving as a platform to mount helmet mounted devices (HMD) such as night vision goggles (NVG). However, aircrew flying air mobility and air refueling aircraft do not wear flight helmets although they must be able to use these HMDs during their missions. Similarly, ground crews, such as regulars, maintainers, bomb loaders, and aeromedical evacuation personnel operating at night use a head harness to mount their NVGs in lieu of a helmet, as do ground troops driving or navigating in a terrain vehicle. The platform needs to fit correctly and accommodate the targeted anthropometric range of heads so it is comfortable and stable while NVGs are in use. Factors such as NVG weight, distribution of weight, and system center of gravity are important to aircrew fatigue, neck strain, injury due to egress, and the system’s effectiveness. Infoscitex proposes a solution which addresses the most important issues when using a non-helmet mounted HMD/NVG by adapting a component of a system that has been successfully in use for decades. In Phase I, Infoscitex will design the overall system, fabricate prototypes, and perform a detailed simulation of the device under realistic operating conditions.

Title:Advanced Head Mounting Environmental Device for NVG
Abstract:To address the Air Force need for a lightweight, durable head-mounted system that allows the use of Night Vision Goggles (NVG) without a bulky helmet, POC proposes an Advanced Head Mounting Flight Environmental Device (AHMED) for the NVG based on a new head harness (wearable over the chemical mask) with a capless conformal strap going under the wearer’s chin with chin bone support. The AHMED’s unique head harness with a chin strap compensates the torque created by weight of the NVG device located in front of the user’s eyes, and its NVG disconnect device aligns the NVG relative to the user’s eyes. Innovations in AHMED’s novel design provide stability of NVG and preserve compatibility with the chemical protection assembly. The Phase I effort will demonstrate the feasibility of the AHMED system by presenting a preliminary design analysis that demonstrates minimal force stressors on the head and minimal fatigue on the neck for a variety of crew head shapes and sizes, and by assembling and testing a scaled-down demonstration prototype. One or more prototype devices will be built to ascertain the proper fit and to identify potential issues related to force concentrations on the head and neck fatigue.

Title:Pedagogically Adaptive Scenarios for Training – Automated! (PAST-A!)
Abstract:Soar Technology proposes to build PAST-A! (Pedagogically Adaptive Scenarios for Training – Automated!), a tool to generate and deliver training scenarios that not only target specific training objectives, but can provide trainees with the deliberate practice needed to support skill acquisition. PAST-A! enables trainers to create scenarios by specifying desired training characteristics and scenario requirements. Scenarios will then be generated from a library of existing engagements encoded using an engagement markup language (EML) that specifies important training meta data, mission characteristics, Distributed Mission Operations (DMO) configurations, and scenario execution scripts. PAST-A! will not only generate scenarios of desired complexity that satisfy a given set of training requirements, it will also generate pedagogically appropriate branch points and monitor trainee performance to help trainers and operators make instructionally sound adaptations during scenario execution. In addition, configuration files for the generated scenarios will be output to the DMO, automating the initialization of scenarios for the operators. PAST-A! will include an expert diagnostician agent to monitor trainee performance during scenario execution, providing both instructors and operators with real- time assessment information, thus facilitating real-time scenario adaptation (through choice of scenario branches or other real-time changes).

Title:Intelligent Scenario Generation Tools for Distributed Mission Operations (DMO) Training and Rehearsal
Abstract:Sonalysts, Inc. and Aptima, Inc. (the Team) propose to research a proof-of-concept software solution that will be able to assess a student, team, or team-of-teams training record(s) to determine the needed instruction to continue, enhance, review, or reiterate training objectives for the Distributed Mission Operations (DMO). Mission Essential CompetenciesSM will be used in our evaluation, analysis, and data collection to determine a more precise curriculum (syllabus) to be used. The Team is looking to employ a scenario generator, that with a Domain Expert and an Instructional Expert, will be constantly monitoring actions of participants. Unmet training objectives will be handled by dynamically reintroducing them into the current scenario via the scenario generator. Failures will be addressed to the participant(s) during debriefing and the individual’s or team’s model will be updated with all outcomes. This solution will be extensible to a variety of training domains, from tactical employment (an F-16 4-ship working with an AWACS Air Weapons Officer) to operational command-and-control (the Air & Space Operations Center), and should be extensible to a variety of training environments, from single-seat fighter simulators to distributed, multi-site exercises.

Title:Live, Virtual, and Constructive (LVC) Common Performance Measurement Development, Tracking, and Warehousing System
Abstract:With the migration towards integrated LVC training there is an increasing need to understand human performance both within and across systems and environments. The problem with current data formats is that they are often incompatible, with no common specification across training environments and systems. As a result, it is nearly impossible to effectively and efficiently identify, generate, extract, and track performance data across LVC environments and systems, thus hindering current efforts to assess trainees’ performance as they interact with live, virtual, and constructive components of an exercise. Col. Louis Olinto, Commander of the AF Agency for Modeling and Simulation, suggests “no longer is there an option for stand-alone systems”. We argue this statement applies to stand-alone and incompatible data formats as well, and is why we will develop a system that enables development, analysis, and usability of integrated performance data from LVC environments in support of performance assessment and review by achieving (1) a universal tagging specification for extracting performance data, (2) an integrated warehousing system for performance data, (3) a common method for identifying the data type (system, observer, communication) and source (LVC) needed to produce useful and integrated measurement, and (4) a method for presenting integrated performance data.

Title:A framework for intelligent Fusion Of Real-Time Measures Across Live-Virtual-Constructive Environments (FORMAL)
Abstract:While billions of dollars have been spent over the past several years on the development of training systems, testing infrastructures, and Live- Virtual-Constructive (LVC) interoperability, there is still no common approach to objective human performance measurement. The purpose, after all, of a Distributed Mission Operations environment is to deliver comprehensive training exercises to the warfighter, to improve warfighter competencies, skills, and knowledge. The reliable and valid objective measurement of individual and team performance within these environments is crucial to identifying the true impact of such exercises on warfighter readiness. To address the need for improved objective human performance assessment, we propose to design and demonstrate a framework for intelligent Fusion Of Real-Time Measures Across Live-Virtual-Constructive Environments (FORMAL). The primary goal of our FORMAL framework is to design seamless, scalable, and sustainable technology for defining, capturing, and disseminating complex continuous human performance objects across heterogeneous data environments. To accomplish this goal, we will leverage our unique experience in both data fusion systems and human performance assessment to design a framework that uses of best-of-breed computational intelligence methods and cutting-edge data storage and access techniques to capture, aggregate, correlate, distribute and share objective performance measures.

Title:Binaural Capture and Synthesis of Ambient Soundscapes
Abstract:Advanced Acoustic Concepts (AAC) will develop a reliable, validated, and fully documented system for digitally recording ambient soundscapes and resynthesize the desired soundscape for binaural presentation to human listeners via headphones. The system will take advantage of the established acoustical signal processing technology of AAC and the state-of-the-art psychoacoustics research and audio recording and processing expertise of Montana State University and Dr. Rob Maher. The system proposed by AAC will exploit the directional recording capability of the microphone array through the process of beamforming. The system will also be able to reproduce a given soundscape based on known parameters using a database of existing auditory environments and statistical models. This will allow the system to reproduce a variety of different listening environments to fit particular user applications.

Title:Binaural Capture and Synthesis of Ambient Soundscapes
Abstract:A system for the accurate capture and recording of the audible range of a 3D spatial sound field in its raw information laden form absent of unnatural alteration, all effort in support of subsequent re-synthesis and re-rendering to any attitude chosen by a listener. Such a system has not been found to yet exist. Our initial solution is a feasibility study extending B-format microphone techniques to 0 dB SPL coupled with novel spatial equalization of the w, x, y, and z components of the calculated sound field. Storage of raw audio from the tetrahedron of microphones and their calibration characteristics preserves basic field data for later improved analysis. A fact we will use to repeatedly study and propose methods for the identification of the separable components or "sound objects" from the soundscapes. Cataloging the sound objects characteristics and soundscape visitation pattern will facilitate synthesis of artificial but similar sounding environments. Ultimately, a listener will be able to observe the synthesized or captured sound field from selectable attitudes through selectable HRTF transfer functions or other improved schema. The primary market outside defense applications of the technology will likely be interactive game developers that are continuously pressured for novel differentiation of their product.

Title:Binaural Capture and Synthesis of Ambient Soundscapes
Abstract:Phase I work is proposed to design, to begin implementation of, and to evaluate a high-quality, portable soundscape capture and synthesis system. The aim of such a system is to record all relevant acoustic information in a particular environment so that it can be re-synthesized for subsequent presentation to a human listener. The current effort will yield a system where the synthesized soundscape preserves both the source levels and perceived source locations of the original soundscape. Source levels will be captured and synthesized accurately over a dynamic range that spans from the threshold of hearing to 110 dB SPL and over a frequency range spanning 100-12000 Hz.. Realistic source localization cues will be provided in the form of (1) binaural (ITD and ILD) cues resulting from microphone mounting on a cylindrical model head and (2) spectral cues resulting from directional microphone-cluster processing. Additionally, the synthesized soundscape will permit listener head-movement in order to increase the realism and sense of immersion. The resulting system will be evaluated to verify level accuracy over the desired dynamic range and the equivalence of source localization and masking between the original and synthesized soundscapes.

Title:SATCAST-Space Awareness Toolkit for Calculating Anomalies to Satellite Tasking
Abstract:The potentially catastrophic impact of enemy attacks on U.S. space assets, hence military missions, has led to recent efforts to improve Defensive Counter Space (DCS) workflow capabilities by increasing Space Situational Awareness (SSA). Critical for enhanced SSA, and therefore DCS workflow, is the ability to (a) distinguish natural space weather effects from enemy attacks on satellites and (b) assess satellite functionality and its impact on mission capability. Aptima proposes to develop a proof-of-concept of a Space Awareness Toolkit for Calculating Anomalies to Satellite Tasking (SATCAST). In Phase I, the Aptima team proposes a two-pronged approach to develop a system to augment Space Situational Awareness (SSA). First, we believe a dynamic interface is needed to support the range of users and variety of tasks supported by SSA. Second, we propose to utilize historical space weather data and associated platform effects as a way to devise decision support algorithms and models. The algorithms and database will be designed to aid in discriminating natural phenomena from hostile acts, predict potential impact on current and future missions for planning, contribute to the Single Integrated Space Picture (SISP), and preserve Space Superiority for our nation.

Title:Achieving SSA Through Representation of Meta-information and Intelligent Search Technology (ASTROMIST)
Abstract:A critical element of our global military dominance is the overwhelming capabilities afforded by the US military space segment. Successful space operations are dependent upon accurate and actionable space situational awareness (SSA), a concept that goes beyond simple cataloging of the location and orbit of objects in space to include the ability to identify and discriminate natural and man-made phenomena in space. Current tools to support SSA have limited capabilities for data exploration, selection, search, and pattern recognition, and there has been no effort to integrate workflows across various systems. To address the need for an aid to bolster space situational awareness, we propose to design and demonstrate an extensible system for Achieving SSA Through Representation of Meta-information and Intelligent Search Technology (ASTROMIST). Three core components characterize our approach. First, we will perform a Work-Centered Support System (WCSS) analysis on the domain to develop a structured categorization of factors commonly considered in space operations, with a specific focus on space weather. Second, we will design and demonstrate a system to visualize relevant information and meta-information, and provide automated pattern recognition through intelligent agent-based search. Third, we will develop an evaluation methodology to determine the effectiveness of the developed techniques.

Title:Border Gateway Protocol with Mobility Extensions
Abstract:The inter-domain routing protocol BGP (Border Gateway Protocol), was designed for statically configured land-based networks which experience infrequent topology changes. BGP is remarkably successful in the stable “network-of-networks” environment it was designed for and is one of the fundamental protocols of the Internet. Any internetworking scheme that will connect to the Internet today must be compatible with BGP. Cutting-edge military and commercial networks have begun to undercut some of the fundamental assumptions on which BGP is based. Mobile Ad Hoc Networks (MANETs) are becoming more prevalent and will continue their growth. MANETs are characterized by frequent topology changes and geographic movement of nodes. Indeed, in the Mobile Airborne Network and other military applications, entire MANET networks become mobile. The task of maintaining a stable, reliable routing mesh between “networks-of-networks” where the networks themselves are inherently mobile strains BGP to the breaking point. The Border Gateway Protocol with Mobility Extensions (BGP-MX) is the initial phase of an eventual replacement for BGP. BGP-MX will control mobility-induced configuration changes to the underlying BGP protocol. The approach will maintain full compatibility with existing BGP networks, while overcoming the static nature of existing BGP implementations and allow for seamless integration of MANETs into the GiG.

Title:Interdomain routing for mobile ad hoc networks (MANETs)
Abstract:MANETs are highly susceptible to fluctuations in wireless link quality due to inherent mobility. Mobility results in frequent changes in the propagation environment. Periods of connectivity interspersed with periods of link outages occur with durations being a function of mobility patterns and suitability of protocols in handling such topological changes. Establishment of reliable routes between multiple MANET networks becomes a challenging problem that the traditional inter- domain networking based upon BGP/TCP connectivity cannot address. Of interest in this SBIR is the development of robust routing strategies to connect MANETs with heterogeneous links. We argue that an inter- domain routing framework for MANETs must consider attributes of individual networks to choose routers and routing protocols. We propose a framework BGP-MANET that is able to make router and routing-protocol decisions and adapt the choices to changes in attributes of participating networks. An approach is included to optimally select inter-networking routers and routing protocols as a function of MANET capabilities, MANET link failure behavior and optimization metrics of intra-networking protocols. A multi-modal optimization technique is proposed to accommodate ingress and egress node parameters within a framework comprising: Strategies in selecting inter-domain routers; Route computation strategy; Route Adaptation strategies with changing MANET behavior and deployment environments.

Title:BESTNET: Behavior Signature of Terrorist Networks
Abstract:Operational terrorists organize their activities largely through small groups based on relationships among friends and family. Their operations and organizations must stay invisible to survive, while coordinating activities in real geophysical locations by actual actors using real resources. Finding patterns within these activities is critical to disrupting hostile actions, but these patterns are embedded in innocuous activities. This raises severe data and analysis problems: too much highly fragmented, noisy data, too complex for human analysts to comprehend. Identifying and disrupting terrorist organizations requires tools to analyze networks of individuals, organizations, activities, and resources. The Behavior Signatures of Terrorist Networks (BESTNET) system will help analysts to identify and track people, places, and resources in adversarial organizations by fusing data of multiple types from multiple sources. It will go beyond SNA approaches by explicitly considering physical locations, activities, and resources, as well as people. BESTNET builds upon Aptima’s proven network identification technology, NetSTAR, which performs probabilistic network pattern identification on noisy data about network nodes, links and their attributes. We will link its rich network analysis capabilities with our existing technology for cultural modeling, and will further extend it by modifying organizational optimization methods to assess mission performance of alternative RED organizations.

Title:Enabling the Modeling and Destabilization of Terror Networks using a Novel Rule-Based Boolean Pseudo-Dynamic Approach
Abstract:The primary objective of this effort is to design and develop a platform enabling the analysis of terror networks using a novel systems-biology based Boolean Pseudo-Dynamics (BPD) framework. This platform will involve development of strategies to identify the critical individuals within the terror network using both static centrality based, and BPD based dynamic metrics that account for an individual’s contribution towards the robust and efficient operation of the terror network. In Phase I open- source terror networks will be identified and the network interactions will be described using logical Boolean rules that take into account metrics of strategy, task, trust, and monetary exchange. Successful completion of the Phase I effort will result in a platform comprising a suite of tools enabling the analysis of critical individuals responsible for functioning of the terror network based on novel systems biology- centered, and social network analysis approaches. In Phase II, the project scope will be expanded to include additional computational algorithms and a GUI, with the goal of demonstrating terror network destabilization strategies via node insertion and/or deletion. Validation of the proposed approach will also be undertaken for a larger network comprising of greater than 100 individuals.

Title:Social Networks in Context
Abstract:The asymmetric threat poses perhaps the most dangerous risk to US forces and assets both overseas and at home. Because of the sheer amount of data available, building dynamic, complex social networks to represent terrorist activities can be very difficult. To overcome this problem, we must identify and utilize advanced techniques to automatically build social networks while also understanding the context they represent. The Decisive Analytics Corporation (DAC) Team proposes an approach termed SOcial Networks In Context (SONIC). SONIC builds on social networking capabilities DAC has already built and additionally provides the capability to identify and understand the roles of different nodes, understand the semantic relationships between entities and automatically identify important clusters of entities within a dynamic social network. Our advanced algorithms developed under this effort will be immediately tested on live data from the theater through DAC’s BOBCAT system – a tool that is on the GSA schedule and in the hands of the Warfighter performing predictive analysis on Iraq data today.

Abstract:Mayflower Communications Company, Inc. (Mayflower) proposes a Topology Management & Control (TM&C) technology, the Real-time Optimal Management of Airborne Network Topology (ROMANT), to meet the Air Force objective, namely, to develop an approach for dynamic network topology management and control. The proposed ROMANT TM&C enables dynamic Topology Management & Control with minimal signaling overhead. The ROMANT system continuously discovers and assesses the current topology, determines how it could be optimized, and then controls the network resources to achieve this optimal topology. ROMANT technology uses efficient distributed algorithms for topology assessment and optimization. ROMANT technology is designed to provide reliable and dynamic TM&C in a network whose nodes are widely varying in capability, capable of high dynamics and high-speed mobility. The proposed ROMANT technology leverages Mayflower’s expertise in airborne networking, and builds on technology developed under several SBIR programs and Internal R&D. The ROMANT system, when proven feasible in the Phase I study for the Air Force application, has enormous potential for military and commercial applications. Mayflower will develop a cost effective ROMANT prototype system in Phase I and II, and ensure its commercialization in Phase III and beyond.

Abstract:The array of rapidly-improving sensors onboard combat aircraft shows great potential to enhance the current situational awareness capabilities of the United States Air Force. Such non-traditional sensors collect a wide and diverse range of data that can offer a more accurate and comprehensive Common Operational Picture of the battlespace when fused with conventional ISR collection capabilities. At present, much of the utility and timeliness of this data is lost due to separation and stove piping of these systems such that fusion with conventional ISR systems can only be performed with human intervention. The Department of Defence’s Global Information Grid (GIG) will need to provide shared situation awareness for Full-spectrum Dominance of the battlespace by the warfighter by establishing machine-to-machine interfaces to facilitate the automated discovery, understanding, use, and sharing of the information and services accessible via the GIG.

Title:Unconventional Sensor Data Access and Integration
Abstract:Non-Traditional Intelligence, Surveillance, and Reconnaissance (NTISR) is a growing capability for the US military. The concept of every platform, vehicle, soldier, sailor, and airman being a sensor contributing to situational awareness of the operational environment is now firmly entrenched in the psyche of commanders. However, much of the information these non-traditional sensors provide is not readily available in a format that is useful to intelligence analysts. In particular, many of the imaging and video sensors use non-standard data formats lack important metadata tag information to assist analysts with exploitation and dissemination of the data. Securboration has teamed with Lockheed Martin Aeronautics Company to develop the Semantic Processor for Unconventional Sensors (SPUNCS). SPUNCS will access unstructured, imagery-based, sensor data, reformat the data into DoD standard formats and tag the data with both required fields and more semantically rich fields to aid exploitation centers, analysts, and decision makers in using the information. Combining Lockheed Martin Aeronautics’ expertise in aircraft sensors and data formats and Securboration’s expertise in NTISR and semantic web technology, we will create a marketable technology for the US military and any commercial enterprises dealing with unstructured imagery data.

Title:Predictive Clustering for IED Defeat
Abstract:Proliferation of sensors, particularly on board unmanned platforms, is quickly enabling persistent surveillance of areas of military interest. The ability to collect and store such surveillance data over large areas and long time periods provides a rich database to mine for patterns of IED activity, but current data mining is human-intensive and limited to forensic analysis of IED events to identify those who emplace and fabricate the IEDs. We propose to extend current capabilities to predictive analysis by developing an automated tool which predicts IED events (locations and times) based on historical data, to estimate patterns, and on real time data, to detect and extrapolate emerging instances of these patterns. Our predictive clustering algorithm computes a list of predicted threat events based on real time data, prioritized by likelihood and characterized by statistical uncertainty of location and time of each event. Complementing the predictive clustering algorithm, a forensic clustering algorithm processes historical sensor data and threat events to estimate parameters in the predictive clustering model. The Phase I effort will develop prototype predictive and forensic clustering algorithms and evaluate them using simulated data to determine performance operating characteristics and using realistic historical data to evaluate military utility.

Title:Defeating Emplaced Improvised Explosive Devices (IED) Using Fusion Algorithms
Abstract:The proposed Potential IED Threat System Plus Plus (PITS++) is an adaptive software system that quantitatively predicts the timing and location of IED emplacements by fusing geographic and social/political/demographical features. It combines SET Corporation's IED emplacement prediction algorithm with Lehigh University's case- based reasoning expertise in order to fuse multiple data sources and make predictions. It is an extension of our previous PITS work under DTO funding that demonstrated statistically significant performance. The original PITS system uses reinforcement learning technique to predict IED threats from geographic features. PITS++ extends that work in three important ways: 1) explicitly addressing the timing of IED emplacement; 2) incorporating machine learning methods to deal with non-linearity in the system; and 3) incorporating case-based reasoning technology to consider non-geographic features. We believe the enhancements will make the PITS more robust and more accurate in its IED emplacement predictions.

Title:Defeating Emplaced Improvised Explosive Devices (IED) Using Fusion Algorithms
Abstract:IEDs are primary insurgent weapons that have caused almost half the U.S. casualties in Iraq. To date, our response has included improved vehicle armor, persistent surveillance, and electronic warfare to defeat Radio-Controlled IEDs. The CREW Duke system developed by SRC has been a phenomenal success in jamming RC-IEDs and has saved countless lives with over 12,000 units delivered. RF signal characteristics and vehicle positions are now recorded for post-mission analysis. These logs provide a sampling of the RF environment and history of U.S. convoy movements. Long-term GMTI radar detections of moving targets are also being recorded to support manual forensic analysis. TSC and SRC propose to fuse diverse data from GMTI radar and CREW Duke logs to predict IED attacks so that convoys can be warned to avoid high risk areas or change their operating procedures. In Phase I, TSC will enhance our existing anomalous movement detection algorithms to discover where insurgents may have emplaced IEDs. Our subcontractor, SRC, will help identify the best combination of information derived from CREW Duke logs, GMTI radar data processing outputs and other geospatial / intelligence sources to predict IED attacks. In Phase II, our team will mature and further evaluate this system concept.

Title:Robust Assured Paradigm for Information Distribution in Airborne Networks (RAPID-AN)
Abstract:Mayflower Communications Company, Inc. (Mayflower) proposes a multilayer information distribution technology, the Robust Assured Paradigm for Information Distribution in Airborne Networks (RAPID-AN), to meet the Air Force objective, namely, to develop intelligent, efficient, and robust data distribution approaches for one-to-many and many-to- many data exchanges over airborne networks. RAPID-AN is built with an intelligent framework that can distinguish different traffic types and provide different levels of QoS based on the existing policy context, and ensure their end-to-end delivery. RAPID-AN also contains network coding mechanism to provide very high throughput for group communications. The network coding mechanism will be specifically designed to counter the effects of high dynamics and high-speed mobility. The proposed RAPID-AN technology leverages Mayflower’s expertise in airborne networking, and builds on technology developed under several SBIR programs and Internal R&D. The RAPID-AN system, when proven feasible in the Phase I study for the Air Force application, has enormous potential for military and commercial applications. Mayflower will develop a cost effective RAPID-AN prototype system in Phase I and II, and ensure its commercialization in Phase III and beyond.

Title:Cognitive Airborne Networks for Defense Operations (CAN-DO)
Abstract:The objective of the CAN-DO project is to create an adaptive cognitive network whose components work together within the rapidly changing challenges and constraints of an airborne tactical wireless MANET to enable fast and reliable delivery of one-to-many and many-to-many information. mZeal Communications and teammate iRobot envision such a network as an information-delivery framework capable of modifying its own behavior: a resourceful, clever, and self-aware system of cooperating actors with plans and goals. According to this vision, the resources for which the network is responsible include not only the traditional nodes, ports, packets, and interfaces, but also the content and meaning of the information it carries. The central focus of our proposal is cross-layer network architecture, the sharing of information between layers of network function that have traditionally hidden their information from one another, as a unifying principle for solving the problems of one-to-many and many-to-many data exchange over an unstable infrastructure. We also identify the key helper technologies that will act together to make the architecture real: Software-Defined Radio, distributed intelligent agents, peer-to-peer multicast and adaptive applications.

Title:PSIR (Predictive Societal Indicators of Radicalism)
Abstract:Although a number of political governance and human rights indicators have been developed over the years, there are no analytical models that map these societal indicators to future radicalization. Here, we propose to research and develop an analytical software tool, PSIR (Predictive Societal Indicators of Radicalism) that predicts future radicalization based on current and historical societal indicators. For the societal indicators, we will evaluate scored political governance indicators collected in comparative political science research. For the radicalization metrics, we propose to develop a scoring process based that uses our in-house geocultural knowledge and statistics based on the MIPT Terrorism Knowledge Base. We propose to develop models that find the causal relationships between the societal indicators and radicalism metrics, and the parameters that define quantitatively the dependency among these indicators. Our tool will enable the analysis and prediction of radicalization across various dimensions, different regions, and countries in a GIS visualization environment. Our approach also learns the temporal evolution of these indicators so that the analysts can make predictions on future value of radicalization based on changes in current conditions. Our tool will help commanders develop more effective plans that address the cycle of behaviors sustaining criminal activity and IED networks.

Title:Mitigate IED threat by Leveraging an Effect-based Approach
Abstract:Improvised Explosive Devices or IEDs have proven to be the insurgency’s most effective method to date in Iraq and Afghanistan for countering the military superiority of coalition forces. Their consequences are devastating to coalition troops and their use derails Combatant Commanders from establishing security, stability, and paving the way to meet U.S objectives. DoD has spent billions of dollars looking at ‘hardware’ solutions to the IED problem, but the positive results have been short lived. Clearly, to succeed against IEDs in present and future conflicts requires more than a pure military ‘hardware’ solution. The key is to understand the root cause and effect relationships motivating and enabling terrorist activities. To this end, Securboration is teaming with Dr. Eugene Santos from Dartmouth College to develop the Effects-Based Approach to Neutralizing IEDs, or EBANI. The concept is an effects- based computational model that incorporates cultural, motivational, historical, political and economic root causes throughout assessment, what-if analysis, and prediction of terrorist activity. While EBANI focuses on the IED threat, IEDs are basically a tool terrorists are using in an attempt to achieve their goals. The effects-based techniques in EBANI are also applicable to countering the terrorist’s next, currently unforeseen weapon.

Title:A QoS Plan for IP-based Data Sharing Between the GIG and SWIM
Abstract:A QoS Plan (QoS-P) uses networking resources intelligently and dynamically, rather than using a hardware surfeit to achieve similar results. As more real-time applications are deployed in an IP setting, implementations of historical IP “best efforts” QoS do not suffice—in an IP-based network, especially one employing TCP, a QoS-P cannot simply emphasize control of the topological path and timing of differing protocols/data types—unknown future participants are able to alter QoS-P efficacy unless governance requires entrance into a known SLA creating end-to-end functionality. This possibility for change is inherent to IP’s historical vision and purpose as the “common glue” for diverse and transparent protocols, unlike predecessor ARPANET, which left reliability to its hosts. Topia acknowledges that network QoS is an essential function of IP and that hosts must be included in any comprehensive QoS-P. A QoS-P could not be built for IP in a random system. However, GIG and SWIM are net-centric and service-oriented, with SLAs (within the SOA service contracts) at their interfaces, and this makes a realistic network-wide QoS-P possible. This proposal ties these aspects of IP and of more traditional QoS-Ps to develop a realistic QoS-P for the transfer of radar data between GIG and SWIM.

Title:Information Sharing between the Global Information Grid (GIG) and the System Wide Information Management (SWIM) system
Abstract:The DoD and FAA have the need to share information between the GIG and the SWIM networks. Specifically, radar data between aircraft, ground radars and ground Air Traffic Management facilities must be exchanged to ensure safe and efficient operation of the aviation system. Building a real-time net-centric capability for sharing radar data in a multi-level security environment presents new and unique challenges. Many obstacles must still be overcome before a truly interoperable data-sharing environment that operates across political boundaries and security domains can be realized. Trident Systems proposes to design and develop the GIG-SWIM Gateway (GSG) to address this need. The GSG will utilize the CS-2000 content processing platform as the central component to provide secure, real-time data sharing. The CS-2000 is a compact, modular, high-speed network appliance capable of handling a wide range of applications and multiple simultaneous functions. Additionally, Trident will develop priority schemes and QoS plan suitable for handling FAA radar data tracks and other SWIM data. The recommend policies, including data security classifications and priorities, will be implemented & tested on GSG. In summary, the GIG-SWIM Gateway will enable the exchange of radar target reports between the GIG and SWIM network with minimum latency.

Title:Multi-Sensor Tracking and Fusion for Space Radar Application
Abstract:Black River proposes a solution for Space Radar Multi-Sensor Tracking and Fusion that considers the specific advantages and challenges offered by LEO and MEO constellations. Our approach to this research topic is three-fold in that we will characterize the expected yield of the radar modes given various scenarios, develop a tracking and fusion methodology, and develop a closed loop end-to-end simulation architecture for performance evaluation. The multi-sensor/mode, multi- target tracking and fusion problem is addressed with a fully featured state-vector that consists of kinematic and pose estimates as well as feature attributes derived from HRR, SAR, and ISAR products. The fully featured state-vector is ideally a blueprint of the target, but in reality it is a sub-sampled vector with more dimensionality than kinematics alone. The advantage of the fully featured state-vector is that it can be used in the track-to-measurement assignment process or in a track-to-track fusion process. Another key component is an architecture that includes a sensor resource manager that is necessary to schedule the specific radar modes while optimizing collections and radar energy over multiple areas of interest.

Title:Multi-Sensor Tracking and Fusion for Space Radar
Abstract:The proposed effort will implement and demonstrate novel techniques to significantly enhance the ability of space radar to track surface moving targets through the fusing of target HRR profiles with SMTI detections on multiple space radar platforms. This work builds upon our recent space radar simulation and HRR feature-aided space radar ground vehicle tracking efforts. Unlike other approaches, we do not make a priori assumptions regarding the signatures of ground targets, i.e., pre- measured HRR signature data or training data sets are not used. Hence, our method is not limited to previously characterized vehicles and is inherently robust. We intend to demonstrate space radar HRR feature-aided tracking algorithms in a multiple satellite space radar simulation with revisit intervals of 30 seconds or greater.

Title:Multi-Sensor Tracking and Fusion for Space Radar Application
Abstract:A constellation of Space Radar (SR) sensors provides the capability to track surface moving targets to a high degree of accuracy. The incorporation of target characterization information from High Range Resolution (HRR) and Inverse Synthetic Aperture Radar (ISAR) modes into tracking and fusion (TAF) algorithms provides enhanced information to the intelligence analyst and decision maker. This study will examine the ability of multiple sensors to provide accurate position and identity of moving targets. Extremely accurate states are required to support imaging algorithms used to discriminate military targets from civilian targets. Accurate imaging of targets of interest requires sub-meter range accuracy as well as precise knowledge of the target heading which is related to the velocity vector accuracy. The tracking algorithms must provide range accuracy on the order of meters depending on the target spacing and scenario; the imaging pre- processing algorithms can reduce this error to levels approaching fractions of a resolution cell. Stringent requirements on heading accuracy may be obviated by the use of prominent point tracking in the case of ISAR images. The Radiance tracking and fusion (TAF) Tool has been used to investigate a number of different types of multi-platform radar sensor architectures.

Title:Wide Bandwidth Photonics Based Beamformer
Abstract:An innovative concept for a scalable beamformer that can be applied to the full range of Air Force radars is proposed. The concept is photonics based and currently supports transmit/receive applications over the 0.1 to 20 GHz band. The design provides a digitally controlled True Time Delay beamformer effectively adapted to a phased array in any portion of the spectral coverage. Fine pointing resolution is consistent with the proposed implementation. The Phase 1 approach will demonstrate the key beamformer characteristics followed by a Phase 2 program that will miniaturize the design and test a multi element implementation. Agiltron is working closely with BAE Systems on this unconventional approach leveraging Agiltron’s recent breakthrough in manufacturing high performance fiber delay lines and variable optical attenuators. The proposed concept overcomes the deficiencies associated with electronic beam forming components, offering frequency independent performance of controlling phase and amplitude in a small, lightweight package with minimal power consumption. Our approach provides unprecedented performance in terms of wide dynamic range, extremely low microwave signal loss, low noise and fast dynamic reconfigurability. The preferred solution set will be determined after developing optimization algorithms for digital receiver/exciters for the US Air Force.

The size and weight objectives of the BFN will be shown to be 1 pound and 1 inch in depth. The RF design of the BFN will demonstrate 7.5-60 degree scan capability over this frequency range with the objective of continuous frequency coverage over the entire band of operation. The TTD module specification will be defined for both RF and physical characteristics. Previous designs from other FIRST RF programs will be used as a baseline for integration of the BFN design. Finally, FIRST RF will demonstrate the approach for building plug-in 16 element arrays with the manufacture and test of a passive 16 element array for physical and mass model verification of a wideband beamforming network phased array design. To validate the overall concept, patterns and bandwidth for this array will be tested with fixed delay lines prior to Phase II TTD module design and fabrication.

Title:Improved Cost Effectiveness in ALON Transparent Armor
Abstract:Aluminum Oxynitride (ALON Optical Ceramic) is a transparent ceramic material which exhibits transmission from the ultraviolet (UV) through the midwave infrared (MWIR), along with excellent mechanical properties. ALON has isotropic optical and mechanical properties, by virtue of its cubic crystalline structure. Consequently, ALON is transparent in its polycrystalline form and can be made by conventional powder processing techniques. This combination of desirable properties and manufacturability makes ALON suitable for a range of applications, from IR windows, domes, and lenses to transparent armor. ALON transparent armor laminates represent the state of the art, offering superior multi-hit performance against armor piercing threats, at half the weight and thickness of conventional glass laminate systems. Currently, the greatest obstacle to widespread use of ALON transparent armor is high cost and limited production capacity. The goal of the proposed effort is to develop improved processing which will substantially decrease the cost, by increasing the yield, and throughput, for producing ALON for armor applications.

Title:Modeling of Nondestructive Evaluation (NDE) Processes for Reliability Assessment
Abstract:The time and cost to perform a comprehensive probability of detection (POD) study are significant and burdensome to the process of deploying new inspection methods and techniques. The complexity and cost of this effort require the development of model-assisted methods to determine the POD of new inspection methods and techniques as they are introduced and maintained as part of a cost-effective maintenance process. TRI/Austin has teamed with other key organizations to demonstrate and validate model-assisted POD (MAPOD) as a technology to speed the development and reduce the costs of POD studies. With participation from Iowa State University’s Center for NDE, Computational Tools Inc., and NDE Technologies Inc.; the TRI Team will design and execute an experimental program to validate models of ultrasonic inspection (UT) of titanium components, and to then validate the MAPOD approach to POD estimation via comparison to a traditional MIL-HDBK- 1823 study. The TRI Team will commercialize the validated UT software as part of the existing UTSIM commercial product. In addition, the MAPOD process will be documented and supporting software developed and commercialized to facilitate the use of POD methods from traditional MIL-HDBK-1823 analyses to MAPOD methods.

Title:Reliability Assessment of Nondestructive Evaluation via Eddy-Current Model-Based Inversion
Abstract:The reliability of nondestructive evaluation (NDE) techniques is currently determined through probability-of-detection (POD) studies that rely on measurments of actual hardware copies of representative flaws. There is now a need to eliminate the inefficiencies and expenses of this method by using model-based standards derived from sophisticated engineering computer codes, that are, in turn, derived from rigorous applications of physical theories. This proopsal applies the concept of model-based inversion that is based upon Victor Technologies' well- known eddy-current code, VIC-3D(c), to solve the problem of reliably assessing NDE techniques. We will introduce the notion of `Probability of Inversion,' and show that the classical model-assisted POD (MAPOD) becomes a simple corollary to it. Furthermore, we will develop a rigorous electromagnetic model for anisotropic media, such as Ti-6Al- 4V, which is a titanium alloy that is widely used in aerospace structures and engines. With these concepts we effectively enter the `digital age' of eddy-current NDE, leaving traditional emphasis on analog instruments behind.

Title:Hybrid NDE Methods for Linear Friction Weld Characterization in IBRs
Abstract:Linear friction welding is an attractive process for performing full blade repair in Integrally Bladed Rotors (IBRs), as it produces good material properties and small heat-affected zones. An effective Nondestructive Evaluation (NDE) method is required for Linear Friction Welds (LFWs) in IBRs that can provide full volumetric inspection. At the same time, the inspection must be performed within the limited space between blades and accommodate the varying curvature of the air foil surfaces. JENTEK’s patented Meandering Winding Magnetometer (MWM) and MWM-Arrays have demonstrated superior performance for detecting cracks in difficult-to-inspect areas of aircraft engine components. Our automated engine disk slot and blade dovetail inspection systems have been awarded the FAA-ATA Better Way Award and are standard practice at U.S. military depots. Under an on-going SBIR program, MWM- Arrays are currently being adapted for scanning air foils, fillets and leading/trailing edges of IBRs. This proposed program will address the need for full volumetric examination of LFWs by combining high frequency MWM scanning with either deep penetration, low frequency eddy current or with UT scanning. We will also evaluate capability to characterize the microstructure of the material in the thermomechanically affected zone adjacent to the LFW.

Title:Nondestructive Evaluation (NDE) Techniques for Repaired Integrally Bladed Components
Abstract:Some modern gas turbine engines utilize integrally bladed rotors (IBR), sometimes called blisks (bladed disks), in the design of the fan and compressor. IBRs are unique because, during fabrication, the airfoil blades are bonded to a hub to form an integral structure, which offers performance benefits over the conventional dovetail design. There are many instances in operation when foreign object damage (FOD) to airfoils leads to the need for a partial or blend repair process. In some cases, material is added to restore lost strength and subsequently machined to reshape the airfoil; and in other cases, the integrity can be restored by simply blending out the FOD and rebalancing the component. Small damage is repaired using various patch-repair techniques. There are strict limits for which partial repair may be used, driven by the location and extent of the damage; and when the limits are exceeded, a decision must be made to condemn the component or apply a full-blade repair process. A full-blade repair requires the airfoil to be cut off and a new full-blade reattached, using a solid-state joining process. The critical nature of these components requires that the new joint of the full-blade repair be free of defects such as internal porosity, planar low- density defects, and surface nonconformities. Good joining procedures and statistical process control are effective in producing defect-free joints; however, NDE techniques must still be employed on a periodic basis to ensure that the structural integrity of the repaired joint is acceptable. The main challenges are that the inspection area has limited accessibility, the object varies in contour, and it has a changing cross section. Keystone is proposing to use pitch-catch ultrasonics and advanced eddy current NDE techniques to assure full coverage, detect

Abstract:The Armstrong Process produces titanium by the reduction of titanium tetrachloride through reaction with sodium. The process allows continuous production by injecting gaseous titanium tetrachloride into a flowing stream of liquid sodium. The process can produce metals and alloys of any composition provided that the constituents have volatile compounds. Because of the nature of the reaction the Armstrong Process inherently produces powder where every powder grain is a homogenous sample of the desired alloy. Currently, ITP has identified (Al, B, Bi, C, Ga, Ge, Mo, Nb, P, S, Si, Sn, Ta, V with volatile compounds boiling at less than 270C and Be, Fe, Hf, In, Zr above 270C but below 490C) potential alloying elements that are suited for the Armstrong Process.

Title:The Low Cost Production of Titanium Alloy Powder Directly from Ore
Abstract:The utilization of titanium is limited by its high cost that is a result of winning it from ores, processing to purify and alloy, and down stream processing to produce component parts. Producing titanium alloy powder directly from ore has the potential to rapidly produce low cost mill products. Known processing to produce titanium sponge has not been demonstrated to produce alloy powder. MER has demonstrated the technical feasibility of utilizing low cost ore, not suitable for other processing approaches, which can be thermally processed to produce a feed from which an alloy powder can be produced in a combined electrochemical-chemical processing technology. The processing will be further developed in collaboration with major titanium alloy powder users to define the types and limits of alloy element modifications possible. Preliminary processing suggest some alloy compositions can be produced in a powder for approximately the same cost as Kroll sponge which offers the potential to dramatically alter the titanium industry. This program will define processing to produce uniform alloying composition in each and every particle, particle morphology, and produce powder and consolidated billets for delivery.

Title:Development of Rapid Prototyping Process for Ceramic Cores for Investment Castings
Abstract:The rapid prototyping of ceramic cores for investment casting of turbine components is a multi-faceted task. Such cores must have sufficient surface quality and dimensional accuracy to meet the rigorous requirements of turbine components. Appropriate RP techniques and materials must therefore be chosen that not only allow green ceramic parts to be produced, but further, meet the demands of subsequent firing, casting, leaching operations and metallurgical response. During development, each of these inter related processing steps must be considered not as a stand-alone development task, but rather as a tightly linked component of an entire production scheme. Therefore, successful development is dependent upon an overall systemic approach wherein each process step undergoes a development program that fully considers the limitations and requirements of the preceding and subsequent processing steps. Consequently, an integrated development approach is necessary in order to arrive at a solution which is capable of meeting all of the goals of this complex task.

The technology will eliminate the high cost and long lead time associated with injection molding tooling and will reduce prototyping costs for advanced cored airfoils by > 50%. The rapid prototyping process will allow parallel exploration of various core designs, which will accelerate the development of higher performance airfoils and turbine engines. The Phase I effort will build on previous related development at TA&T and by our collaborators. Phase I will entail material property evaluation to ensure compatibility with the casting process, fabrication of advanced core designs and assessment of surface roughness and dimensional accuracy. Phase I will culminate with a casting demonstration using cores fabricated by the new process.

Title:High-Temperature, Abrasion-Resistant Coating
Abstract:Fighter aircraft such as the F-35 Joint Strike Fighter (JSF) must fly with precision and reliability, especially in extreme environments. In order to perform missions effectively and economically, the JSF aircraft has many moving parts that are subject to high wear conditions across large temperature and load ranges. Coatings are often used to protect composite surfaces that are located on the outside of the aircraft. Although these coatings are easy to apply, they are generally thin and do not perform above 350ºF (177ºC) without degradation in performance. Advanced wear-resistant coatings that operate at elevated temperature are needed for today’s fighter aircraft. The technical innovation being proposed is the development of a BMI or polyimide coating that will offer high-temperature stability and wear resistance for use in F-35 JSF applications. The research effort will progress from chemical screening and cure cycle optimization of the base coatings, to nano-modifications of the coating, followed by extensive abrasion and TOS testing. A large amount of chemical and physical characterization testing is planned to provide a thorough assessment of each coating. The wear and thermal performance, processing characteristics, and cost benefits for each coating will be determined and compared to the baseline.

Title:High-Temperature, Abrasion-Resistant Coating
Abstract:The F-35 JSF aircraft imposes a demanding set of reliability requirements, particularly in regard to operation temperature. Millions of dollars are spent every year repairing coatings that cannot withstand high temperatures while maintaining mechanical properties, including those on BMI composite parts for the JSF. The current Teflon-filled coating on the F-35 aft boom covers abrades easily during use at 450oF and short durations at 650°F. TRI/Austin proposes an innovative coating approach to utilize a thermally stable vinyl functional polysilazane binder with an inorganic, high temperature, pigment package that will have superior thermal stability coupled with outstanding abrasion resistance. This coating can be spray or brush applied, and test formulations have already shown excellent results. The technical objectives are to develop optimum coating formulations for polymer coated BMI composites and demonstrate superior thermal protection; confirm that the coating provides excellent adhesion, flexibility, and color as well as resistance to abrasion, chemicals, corrosion, and impact; and investigate test methods to confirm the coating's resistance to abrasion at elevated temperatures. This new high-temperature, abrasion-resistant coating should find many applications in military and commercial aircraft as well as in automotive parts, industrial equipment, and improving commodity materials.

Title:Modeling and Simulation for Robust Ceramic Matrix Composite (CMC) Manufacturing Processes
Abstract:Increasing the power density of current jet aircraft engines requires the replacement of conventional high temperature materials by new materials capable of operating at higher temperatures. Ceramics and ceramic matrix composites (CMCs) represent excellent candidates for increased use in hot engine parts due to their ability to withstand temperatures in excess of 2000 C. Due to the complexity of the manufacturing CMCs, limited guidelines exist that can readily transfer between different components. Consequently experimental approaches are needed to develop detailed manufacturing procedures. The extensive development time and budget needed for this approach can be significantly reduced if predictive design tools for the RMI process were available. This work will develop analytical tools to analyze the multiple interdependent physical phenomena of relevance for the manufacture of CMCs. The analyses will be integrated into a design tool capable of providing engineers with an environment to analyze the CMC manufacturing process thus reducing the need for iterative experimental approaches. Consequently, the costs associated with manufacturing critical CMC components will be dramatically reduced and provide engines with improved thrust and fuel efficiency while reducing emissions.

Title:Multiscale Modeling for Melt Infiltration Process in Ceramic Matrix Composite (CMC) Manufacturing
Abstract:CFDRC proposes to develop a comprehensive, high-fidelity commercial quality simulation tool for modeling the melt infiltration process in Ceramic Matrix Composite (CMC) manufacturing. The code will accurately predict the transient melt infiltration process with tightly-coupled detailed physics-based component-level and micro-scale models for the infiltration front and solidification in the porous preform. The foundation for this tool will be the proven multi-physics CFDRC code. In Phase I, we will demonstrate feasibility of simulating melt infiltration processes at the component level through submodels for capillary transport in porous media coupled with reaction kinetics and associated temperature and volumetric changes. In Phase II, we will improve the scope, speed and accuracy of the tool using a novel multiscale modeling approach. Tightly coupled pore-scale multiphase simulations will feed into component-level models with advanced numerical tools unique to CFDRC. These advanced tools include free surface modeling with capillary forces and variable viscosity, surface reactions and heat interactions, particle tracking, parallel processing, and stochastic solvers based on Lattice- Boltzmann and Kinetic Monte-Carlo methods. These capabilities will be coupled and integrated into a user-friendly software package. The development will be performed in close collaboration with Goodrich, a leading CMC provider, to insure relevance and facilitate technology insertion.

Title:Inhibited Electrically Conductive Adhesive for Rapid Aerospace Fastner Preparation
Abstract:Current practices for joining aluminum and composite airframe elements together involves a labor intensive process. Titanium fasteners are hand abraded or grit blasted, installed, coated with a chromated primer, and sealed with an electrically conductive sealer. The process requires both significant labor hours and significant down time, as the chromated primer and conductive sealer must be cured before subsequent coating. The objective of the proposed program is to replace the labor and time intensive multistep fastener preparation process with a single step. Using internal expertise in the areas of corrosion, coatings, and nanocomposites, Luna will formulate a two component adhesive that adheres well to the titanium fastener and surrounding aluminum, prevents corrosion of the metals, exhibits sufficient conductivity, and levels the recess flush to the outer mold line. Through a more complete understanding of the corrosion processes, and a holistic approach to corrosion prevention, the Luna system will be able to save time and costs while removing chromated primers from the preparation process. The proposed material would save direct and indirect cost for the Air Force and be applicable to the commercial aerospace industry as well.

Title:Rapid Method for Aircraft Fastener Surface Preparation
Abstract:Each of the more than 40,000 fastener heads in the F-35's outer mold line must be covered with a special thermoplastic conductive polymer fill prior to application of the primer and final finish coatings that will ultimately define the stealth of the aircraft. This is currently a time- consuming, labor-intensive operation, and the potential for fastener-to- fastener quality differences is high. Systems and Materials Research Corporation (SMRC) proposes development of the Rapid Intelligent Fastener Fill System (RIFFS), an automated handheld tool which the operator simply places over a fastener head. With the press of a button, RIFFS will secure itself to the airframe, accurately measure the cavity depth, then dispense, melt and compress a metered load of thermoplastic material into the fastener head cavity - all in under 30 seconds. Unlike current fastener fill procedures which take considerably longer and leave large amounts of excess thermoplastic material to be removed and disposed of, RIFFS dispenses 1-5 thin dots, designed to slightly overfill the cavity when melted and compressed. RIFFS delivers low power (2 watts) microwave energy to the dots, rapidly and uniformly melting them as a dielectric plunger compresses the conductive thermoplastic material into the fastener head cavity.

Title:Wear-Resistant Coatings for Aircraft Structures
Abstract:An aircraft of today has many moving parts that are subjected to high wear conditions; naturally this puts a high demand on the reliability. The need for new coatings and approaches that improve the wear resistance is clear. Furthermore, a need for smart materials where lifetime indicators can be incorporated is a logical next step in the evolution of coatings. This SBIR proposal suggests an advanced vapor deposition process that can be used to deposit materials combinations that have a high wear resistance as well as a measurable lifetime. The process is suitable for aircraft components with non-line-of-sight areas, such as interior surfaces of pipes or even more complex shapes. The proposal further suggests a combinatorial selection process for the materials combinations that can optimize the compatibility with the substrate material as well as optimizing the wear resistance of the coating. By measuring easily accessible physical properties of the film during maintenance intervals for the aircraft component it will be possible to determine the useful lifetime for the remaining wear resistant film and arrange for replacement prior to failure.

Title:Nanostructured PVD Smart Wear Resistant Coatings for In-Situ Health Prognostics
Abstract:This project is a collaboration between Tribologix, Inc. with core expertise in the deposition and testing of hard wear resistant coatings, and Mound Laser & Photonics Center, Inc., for development of a low cost smart coating wear sensor, and General Electric Aviation, a manufacturer of Gas Turbine Engines for military and commercial applications. Our approach uses the spectral response of layers found in our nanostuctured graded hard coatings combined with a low cost reflectance sensor capable of accurately detecting a change in color as the material is worn away. The focus in Phase I will be to optimize a new class of advanced hard wear resistant coatings which are based on nano composite structures as well as in situ health prognostics. Under this effort we shall grow gradient coatings that vary in color or reflectivity as a function of composition. For example, Titanium Nitride (TiN) is a gold coating, Titanium Carbo Nitride (TiCN) is a pink or blue coating and Titanium Aluminum Nitride (TiAlN) is a dark grey or black coating. These colors vary with the degree of C, N and Al in the coating structure. Each coating type has a unique spectral response. We will use appropriate lighting sources and a spectrometer to quantify and detect the color change as a function of composition. After we have calibrated these measurements, we will then make a gradient coating and measure the color change as the coating is worn away. We will be able to create the wear with a pin-on-disk arrangement initially, allowing us to directly correlate the optical signal with the wear and friction history. We will effectively create a situation in which the optical signal indicates the remaining thickness of the coating, and thus the remaining wear life with out interrupting the rotation of the sample.

Title:Real-Time Control of Laser Coating Removal
Abstract:Energy Research Company (ERCo) proposes the development of an instrument that provides novel real-time control of laser decoating processes by detecting the coating as it is being removed. The technology allows for precise and selective removal of the desired coating layer while preserving any underlying coatings and the base material. The instrument’s real-time operation allows the coating removal rate to be unimpeded and to proceed at its optimum speed. The quality of the decoating process will thereby be greatly improved while throughput of the laser decoating system will be unaffected. ERCo has demonstrated the technique in its laboratory and has shown that very accurate coating removal can be obtained. In Phase I, ERCo will demonstrate the device’s ability to automatically and accurately control the removal of topcoat and/or primer layers while preserving underlying layers and the substrate material. The technology can also be adapted for controlling other coating removal methods.

Title:Characterization and Modeling of TiNi based Foams for Integration into High Speed Penetrators
Abstract:Large shock-loading events generated by a warhead penetrating a hardened bunker are difficult both to characterize and model, making the engineering to protect both the explosive and arm its fuzing mechanism exceeding difficult. Experimentally, shock loads propagating into existing warhead are hard to measure, and therefore make verification of shock and impact models difficult to verify.One solution to this incredibly difficult challenge is to significantly mitigate the incoming shock, such that the measurements of the shock loads are more reliable, increasing the computer simulations and more importantly, allowing for engineering improvements in the warhead and fuzing system. SCT and ARA will characterize and model a novel metal foam material for these applications that has shown excellent shock mitigation at high strain loading.

Title:High Speed Penetration Modeling
Abstract:For High Speed Penetration Modeling of warheads to provide maximum benefit to the Air Force, the development of high fidelity data collection instrumentation and improved diagnostic tools is a fundamental and necessary “first step” to assess the overall effectiveness of these penetrating warheads. The data collection system must survive dynamic, high energy impacts to capture the critical data. Considering that the defensive capabilities of hard targets are ever evolving with incorporation of improved technologies that employ high strength and high performance materials, the need for high fidelity data collection becomes even more important in the future. This proposal presents a robust, low cost, approach to develop small, high performance data collection devices and systems that will provide the operational characteristics to meet these requirements. The proposed development approach has been utilized previously for similar testing requirements when collecting data internal to gun launched projectiles, and sampling multiple sensors configured on devices subjected to explosive events. A development methodology based upon these prior designs forms the basis for further development to address the data collection for high speed warheads, and subsequently provide high fidelity data to simulation modeling tools.

Title:High Speed Penetration Modeling
Abstract:Penetrating warheads filled with High Explosives (HE) can prove ineffective in destroying deeply buried and harden military complexes. The objective of this proposed effort is to develop and empirically validate Finite Element Modeling (FEM) simulations that can accurately represent materials and assemblies response to high speed impacts and harsh environments. Dynamic FEM on representative test articles containing HE will be generated using LS-DYNA, which will give load paths, stress distribution, strains, and component deformation at various impact velocities. The developed LS-DYNA impact simulations will be compared to penetrator tests on test articles containing simulant HE materials at the University of Texas Institute for Advanced Technology. Design of Experiment (DOE) will be conducted to replicate thermal and vibration events resulting from storage and field-use that can adversely affect mechanical or electrical components' function; small-scaled samples filled with HE or HE simulant will be prepared and aged to access the potential effects of micro cracks or voids on detonation characteristics. Analytical tests will be conducted to evaluate changes in HE after accelerated life testing. The results of this research will be improved performance penetrating warheads that are more reliable, predictable, and deliver maximize lethality to harden complexes.

Title:Penetration Survivable Advanced Energetics
Abstract:Corvid Technologies is pleased to offer the following proposal in response to solicitation AF 08-045, Penetration Survivable Advanced Energetics. We will describe our current capability in modeling of heterogeneous material response to damage which may occur during a penetration event. During a penetration event when the explosive is placed under both compression and tension a variety of damage modes can occur which could cause the explosive to not survive the event. These damage modes could include particle fracture, dewetting (debonding), scission, localized shear heating, void collapse, and energetic response (detonation, deflagration, or burning). In Phase I we will propose a modeling and simulation program that utilizes existing capabilities in modeling energetics to advance development of bulk response models in existing production first principle codes. We will layout a model development and improvement plan for Phase II which includes demonstrating the model’s validity through controlled testing.

Title:Penetration Survivable Advanced Energetics
Abstract:It is well established that the heterogeneity of energetic materials at the mesoscale localizes deformation energy, generating “hot spots”. It is imperative to understand the nature of hot spot spatial distributions, as their coalescence leads to sustainable reaction. Given the difficulties in determining hot spot distributions experimentally, this is an ideal scenario for contributions via numerical simulation. However, important mesoscale details are only partially known, including detailed material morphology, inelastic material properties, and appropriate interfacial physics models. Here we propose simplifying the problem by examining two-dimensional surrogate materials with simplified morphologies and interfacial physics, permitting extensive validation data to be obtained. Molecular dynamics simulations will calibrate models for frictional sliding between grains and in cracks, including melting. A particle simulation technology that has been demonstrated to handle interfacial physics exceptionally robustly and efficiently will be validated and then used to resolve hot spot spatial distributions. By examining pristine and damaged systems, the importance of certain mesoscale characteristics will be isolated, and conclusions drawn regarding sensitivity to penetration events. A validated simulation capability will demonstrate the application of existing technology to a tailored, complex system, and provide a firm foundation for examining more realistic systems, and developing improved engineering material models.

Title:Flight Control Technology for Tightly Controlled Hard Target Impact
Abstract:This project develops an innovative, enabling technology for precision attitude control of guided munitions. An imaging sensor system is used to precisely measure airframe attitude relative to the velocity vector, eliminating the time dependent heading angle inaccuracies common to all GPS/INS based attitude measurements. During the downward flight of a guided munition, a body-fixed, boresighted imaging sensor detects the expansion of the scene as the munition approaches the ground. Innovative Image Processing algorithms are used to determine the Imagery Center of Expansion (ICE). Since the scene expands radially away from the velocity vector, the number of camera pixels between the ICE and the boresighted munition centerline is a direct measurement of the velocity vector angle. The Phase I program simulates the imaging sensor, develops image processing algorithms, creates an electrical/software architecture concept for real-time operation, and examines ultra-high bandwidth attitude control actuators required for precision airframe control consistent with the accurate angle measurement from Areté’s imaging sensor system. The Phase II program will develop a prototype imaging sensor system that demonstrates the ability to measure the velocity vector angle in a real- time hardware-in-loop simulation. Phase III commercialization will be encouraged via demonstrations with government and industry primes.

Title:Upstream Energy Deposition for Increased Speed and Precise Attitude/AoA Control of Hard Target Penetrators
Abstract:The proposed approach involves repetitively depositing a line of energy ahead of a high-speed hard-target penetrator. The heated gas will expand, pushing air aside to create a straight, low-density column, through which the penetrator will propagate. This procedure removes over 90% of the drag on the vehicle, enabling much greater speeds, for both propelled and unpropelled platforms. The low-density tube furthermore exerts forces and moments on the body to keep it centered/aligned along the created path. These effects have been verified in a separate AFRL program on hypersonic platforms, and relevant energy-deposition hardware has been built and tested.

Abstract:The U.S. Air Force has significant interest in the development of adaptive structures for micro munition platforms. However, power, mass and cost constraints significantly limits the applicability of existing adaptive structure concepts for these smaller platforms. To address these challenges, CTD is proposing the use of solid-state, electrically- driven actuators that require minimal power and are capable of high actuation rates (>10 Hz). The proposed approach is based on the use of these actuators in combination with CTD’s existing morphing wing- skin technology providing increased wing-morphing functionality. If successful, the proposed technology would eliminate the need for traditional flight control devices such as ailerons. The proposed Phase I plan encompasses requirements definition, prototype hardware design and manufacture, and technology assessment. To that end, CTD has partnered with the University of Florida’s Research and Engineering Education Facility (REEF) to assist in assessing the technology via relevant wind-tunnel testing.

Abstract:Micro Aerial Vehicles (MAVs) provide an important military and civilian capability to very rapidly deploy an aerial platform for surveillance and observation with minimal resources (i.e. single operator). As a surveillance platform they can be used for reconnaissance, target identification, assessing bomb damage, search and rescue, locating survivors, etc. The development of effective MAVs for these missions will require simple, light, power efficient actuators that can be used for control and to morph the aircraft to fit a broader flight envelope as needed by the mission. Radiance proposes to develop a piezoelectric actuator based on the proven concept of PBP actuation as has been implemented in UAV design. This actuator will provide an aero-surface morphing capability as well as control surface action to replace current servo technology. Actuators of this kind have been shown to be simple, lighter and require less power than traditional actuation systems; all aspects that improve the aircraft performance.

Abstract:We will develop "flexible sensing" techniques that will enable a single sensor to perform the functions of both a "seeker" and a "target detection device". One set of approaches will comprise resolution enhancement and other techniques to extract target identification and tracking information, as would be provided by a "seeker", from a low resolution / high update rate sensor. Hyperacuity-based approaches will be considered. The other set of approaches will comprise low latency downsampling and feature extraction circuits that may be added to a high resolution / low update rate sensor to provide target detection information. For Phase I and Phase II, this research will be performed in the context of a target application involving a micro air vehicle tasked to identify a target of interest, pursue it, and trigger an endgame action when sufficiently close. This target application will allow us to develop techniques and identify principles in a real-world context that may be adapted to guided munition and other applications in Phase III.

Abstract:In contrast to the typical single aperture systems found in weapons today, arthropod compound eyes are multi-aperture optical systems.

The applications of artificial compound eye sensors range from highly complex applications such as terminal seeker optics and missile approach warning systems, to guidance sensors for micro-robots. This effort proposes the use of compound eye sensors as a replacement to dual mode sensors for use in target detection, tracking, and guidance integrated fuzing.

Title:Processing for Flexible Sensors
Abstract:AFRL/RWGI seeks performance and cost improvements by pursuing a Guidance Integrated Fuzing (GIF) approach that will enable a single sensor to supply the information requirements for tracking the target from detecting the target through fuzing the weapon. Judicious selection of sensor and clever application of algorithms will enhance the sensor system’s ability to trade off spatial and temporal resolution to enable this revolutionary breakthrough. Current seeker and fuzing sensors are developed separately and each optimized to its intended function. This can lead to increased cost and complexity of the systems, greater SWAP demands (which drives up cost), and increased logistics cost. The key to our approach lies in seeking optimal digital solutions that enhance sensor resolution capability and explicitly enable the system to trade spatial resolution and contrast against temporal resolution. This will stretch the operating range to span the requirements from detecting targets at long range to high rate low latency target position update for fuzing.

On a complex engine with multiple components that produce wear debris, the addition of vibration monitoring can provide a localized prediction of exactly which component is degrading or failing. Data fusion of vibration and ODM sensor data has been shown to improve the statistical performance of bearing and gear fault detection and isolation while simultaneously maintaining or reducing false alarms and missed alarm diagnosis in a test rig environment. This type of integrated monitoring system has not been fully demonstrated on an aircraft engine. This SBIR will integrate the hardware, software, and data from mature, robust, commercially available vibration and ODM sensors into a versatile Engine Health Management (EHM) system. IAC has teamed with GasTOPS for development of this system. The results and systems developed on this SBIR can be directly applied to improving EHM performance for the F135 and other gas turbine engines.

Title:Advanced Oil Filter Load Monitoring for Aircraft Engine Bearing Diagnostics
Abstract:Early indication of impending main engine bearing failure is critical, especially for single engine fighter aircraft such as the JSF. Bearing degradation leading to failure is characterized by increasing amounts of bearing race and rolling element spalling and wear debris entering the engine lube oil flow. The amount of shed bearing debris indicates remaining useful life. Magnetic chip collectors are widely fielded, but suffer low capture efficiency and lack online measurement capability. Aircraft engine lubrication filters, however, capture virtually all bearing damage particulates. Accurately trending oil filter blockage using differential pressure measurements provides useful indication of bearing damage progression. To address the critical need for improved engine diagnostic capabilities, Luna Innovations will advance the state of the art in filter monitoring for bearing diagnostics by leveraging the technical experience of industry leaders to develop and apply load trending algorithms for filter construction and particulate loading specific to aircraft engine bearing damage. Also in Phase I, Luna will investigate the feasibility of directly sampling fluid parameters to reduce filter loading uncertainty. The diagnostic strategy ultimately resulting from this effort will be especially valuable when fused with orthogonal techniques (e.g., vibration monitoring) to provide a robust bearing health monitoring approach.

Title:Information Decision Software Tools for Turbine Propulsion PHM Systems
Abstract:The project will develop software tools to enable optimal estimation of engine fault state in embedded avionics system. The tools will address vulnerabilities of existing PHM systems and allow achieving low (the smallest theoretically possible) false alarm rates while simplifying system engineering and sustainment. The fault states will be estimated/detected from the residuals and BIT data using empirical and/or physical fault models. Existing PHM approaches combine several heuristics for characterization of engine health deterioration and design of engine fault alarms. This project will rely on recent breakthroughs in estimation and optimization that allow integrating all data (discrete and parametric) and all fault states (discrete and continuous) in one optimal solution. The tuning parameters of the solution would include sensor noise covariances, BIT/BITE mis-detection probabilities, fault probabilities, fault interdependencies, and model confidence. First, we will develop off-line tools for model-based system analysis and design. Second, we will develop embedded software functions for computationally efficient on-line implementation of the approach. The embedded computational functions could be employed similar to other packaged mathematical software, such as matrix arithmetics. Phase I will demonstrate viability and performance of the approach to design and analysis of PHM for an F-110 engine vane actuator subsystem.

Abstract:Scientific Monitoring, Inc. (SMI) proposes a novel two-stage comprehensive strategy for fault diagnosis for the purpose of reducing the occurrence of No Fault Found (NFF) events in Propulsion Health Management (PHM) activities. The strategy includes modeling and algorithmic elements that account for uncertainty at two distinct stages in the fault detection process: (a) anomaly detection, and (b) information/decision fusion. The Phase I contract will develop the strategy into a software prototype and assess the prototype using a combination of simulation-based validation testing and experimental validation from actual engine flight data.

Title:Expanding the Processing Capability of On-Line Propulsion Health Management (PHM)
Abstract:Propulsion Health Management (PHM) is viewed by the Air Force as a critical technology for improving aircraft system affordability via reduced maintenance costs, and improved platform survivability and availability . Ideally, PHM eliminates “surprises” in operations and maintenance. DSPCon proposes to develop a powerful, modular, expandable, open- standards addition of processing capability that will increase the speed of PHM decisions by an order of magnitude over current Full Authority Digital Engine Control (FADEC)-based hardware and software. It is anticipated that PHM decisions representing accurate fault isolation with a low probability of false alarm are needed every 20 msec. Through the use of optimized signal processing algorithms and commercially available high speed hardware, the DSPCon platform will provide a greatly improved computational capability over current PHM solutions. The DSPCon platform will accommodate anticipated PHM requirements including sensor data rates of 200kHz or more, and data bus rates of 100 megabits per second or more. DSPCon will consult with major jet turbine engine manufacturers throughout the program to ensure a comprehensive understanding of PHM requirements for gas-turbine engines.

Title:Fast, Reconfigurable Computing for PHM
Abstract:Propulsion Health Management (PHM) of advanced aircraft propulsion systems refers to a multi-faceted approach of sensitive and precise monitoring of gradual subsystems degradation. The objective is to first ensure mission reliability, while extending the useful lifetime of the high- value asset. In applied propulsion engineering research, PHM diagnostics and prognostics have been shown to be feasible in tracking day-to-day engine health; it is expected that real-time engine control functions should be possible. Real-time models running on-board to support Full Authority Digital Engine Control (FADEC) are not only conceivable, but are under active development. Augmenting future FADEC systems with real-time PHM sensor integration, data fusion and decision support algorithms, physics modeling and inlet flow control will require significant computational resources. The U.S. Air Force recognizes the need for technological breakthroughs to support this high-throughput, compute-intense environment. In this proposal, Intelligent Automation Corporation (IAC) outlines a plan to address this critical need for advanced PHM technology with a combined hardware and software systems approach. This approach features cutting edge, Field Programmable Gate Array (FPGA) high-performance computing on military-qualified IAC systems, and a novel software architecture that enables rapid development and deployment of high-level PHM algorithms on this platform

Title:Integrally Bladed Rotor (IBR) Maintenance and Life Management
Abstract:Blade Diagnostics Corporation will integrate a new capability into its Mistuning Inspection Machine so that the effect of aerodynamic as well as structural mistuning can be evaluated when inspecting blend repairs on the F119 1st stage fan. This Smart BlendTM technology will transform the MIM into a virtual engine test for blended blades. Consequently, at the end of this effort a technology will be in place that will allow the DoD to use relatively low cost blending operations to repair a larger number of IBRs/Blisks while reducing the likelihood of HCF failure from mistuning. This capability fits directly with the goals of the DoD’s VAATE program and the P-SAR initiative. With Pratt &Whitney as an active participant in the program, there is every expectation that the capability developed in this SBIR will be promptly transitioned to operational service to meet what are already important Air Force needs. The proposed technology has dual use potential in that it can also be applied to commercial as well as military engines.

Title:Wireless On-engine Health Monitoring of Integrally Bladed Rotors
Abstract:The ability to sustain turbine engine IBRs in a safe and affordable manner is critical. IBRs usually operate in a harsh environment, experience high centrifugal and thermal stresses. Cumulative microscopic cracks at critical loading areas, if not detected and repaired in time, may lead to a catastrophic disk or blade burst and thus engine failure. This proposal tries to address the health management issue of IBR from the inspection and microcrack detection point of view, which is the basis for life prediction and repair. We propose a wireless on- engine health monitoring approach. It applies light, thin film patch transducers to the IBR and inspects rotor for small cracks and embedded flaws. The signal is coupled wirelessly to the sensor patch so that the inspection can be done even when the IBR is rotating. The envisioned system has minimal effect on the rotor performance, instantaneously provides reliable and quantitative data such as crack location and severity level; minimizes and eventually eliminates the need for engine disassembly for purely inspection purpose.

Title:Chemical Kinetics for Vitiated Flows
Abstract:The flame stability in typical augmenters is largely determined by vitiated air composition and high preheat temperature of the incoming flow. Presence of significant quantities of CO2 and H2O in the vitiated air will affect the oxidation characteristics of jet fuels by increasing the third- body collision efficiencies of initiation and recombination reactions. Traditionally, kinetic models are validated against data acquired for unvitiated air. Thus, it is essential to validate the kinetic models against data obtained at typical augmenter operating conditions. Combustion Science & Engineering, Inc. proposes to acquire new experimental data using vitiated air at low pressures. The data will include ignition delay time data (at CSE), laminar flame speed data (at Georgia Tech) and flow reactor experiments (at Princeton University). CSE will also develop a model reduction tool to generate reduced models from detailed kinetic mechanisms that are validated against the experimental data acquired in this project. These reduced kinetic models can be implemented in CFD for practical augmenter simulations for commercial applications. In Phase I, experiments will be performed to obtain low pressure ignition delay time and laminar flame speed data. CSE will also evaluate various model reduction strategies to reduce detailed kinetic models for augmenter applications.

Title:COMPREHENSIVE JP-8 MECHANISM FOR VITIATED FLOWS
Abstract:Despite the importance of jet fighter afterburner designs, there exists very little data on the majority of the individual components of jet fuel, especially JP-8, to enable development of a detailed kinetic mechanism. Although the Multi University Research Initiative program has been initiated for that purpose, it is oriented for the main engine combustor where the process is different from afterburners. A kinetic mechanism for combustion in afterburners raises new level of complexities since the combustion is vitiated: low pressure, minimal oxygen, and high temperature. Innovative Energy Solution is assembling a world class team of experts in chemical kinetics and computational fluid dynamic to develop a robust and sophisticated chemical kinetics module for predicting elementary reactions of vitiated combustion as exist in afterburner environments. This module, for eventual insertion into a computational fluid dynamic package, will go beyond simple chemistry as it will predict relevant micro level chemical reactions during combustion in vitiated flow. Using the unique properties of the single pulse shock tube to generate the needed low pressure rate coefficients, the company is planning an array of experiments for validating and cross-validating the model while taking a lead in defining the fluid dynamic portion of the problem.

Title:High Temperature Permanent Magnet Actuator Motor
Abstract:A transition from a centralized, hydraulically based power source to a multi-source electric power base is eliciting a need for an electrically powered aircraft. This electrical power base will be composed on multiple, independently operated electric units, working together to power the craft. A premeditated obstacle to this innovative approach is achieving a level of power density that will meet weight and volume criteria in aircraft application. High power density electrical machines innately present thermal management issues. These issues stem from condensed power dissipation in a smaller volume and surface area. The temperatures associated with this application demand attention in the motor design and selection of materials that will meet life requirements of an application. SatCon Applied Technology proposes to meet these challenges by developing a motor with high power density, magnet and insulation systems that withstands the aircraft high temperature environment. A feasibility study of permanent magnet formulation, temperature sensitivity, and affecting environmental variables will be conducted. The end result will be a comprehensive understanding of long life insulation systems capable of withstanding high temperatures in a compact motor design. Cooling methods appropriate to manage temperatures in the aircraft will be evaluated and the most appropriate solution implemented.

Title:Starter/Generator Efficiency Enhancement for High Performance Tactical Aircraft
Abstract:Advanced military weapon system platforms place a premium on subsystem weight, space and reliability, while demanding increased power density for ever increasing electrical loads ranging from avionics to advanced high energy weapons. In each of these systems the efficiency of the starter/generator is crucial and designs that will minimize electrical and/or mechanical losses are needed. The overall objective of this proposed SBIR program is to demonstrate the feasibility of minimizing the system mechanical losses such as windage and friction through novel design and integration approaches. Under Phase I, parametric design studies will be conducted, preliminary tests with existing MiTi high speed motor generators will be conducted and a preliminary design of a Phase II test facility will be completed. MiTi® will also assess the impact of proposed modifications to enhance power density and total system weight. Under Phase II, detailed design modifications to an existing MiTi starter/generator will be completed, the hardware be fabricated and tested under full speed and load to demonstrate the efficiency improvements possible by reducing the windage and friction losses. To ensure applicability of the results to the widest range of DOD systems, scaling tests will be conducted.

Title:Windage Loss Reduction for High Speed Electrical Machinery
Abstract:The efficiency of electric motors and generators operating with high rotor surface speeds is reduced due to viscous shear and aerodynamic effects. These losses are generally referred to as “windage loss.” In some specific, high speed machines of particular interest to the aircraft community, it has been suggested that the losses could be as high as 10% to 15% of rated power. For the case of liquid cooled machinery in modern tactical aircraft, heat input at these levels can result in unacceptable fuel temperature rise, leading to undesirable performance tradeoffs. In this Phase I SBIR project, Xdot Engineering and Analysis proposes to investigate two innovative approaches for directly reducing these windage losses. The first is especially relevant to switched- reluctance machines such as those for aircraft applications. The second is relevant for a wider class of machines. Both can be applied with minimal or no change to the overall electrical/magnetic design of the machine. Applied individually, or in synergistic combinations, the aim is to achieve a reduction in windage power loss of at least a factor of 2, with a goal of an order of magnitude or more.

Title:Pump-fed Micropropulsion System for High Performance Nanosats
Abstract:Miniaturization of propulsion systems for small spacecraft presents unique challenges which, to date, have rendered such small spacecraft unable to have significant orbit change/control and attitude control capabilities. Under a Phase I SBIR, Flight Work Inc. will design a HAN- based pump-fed micropropulsion system and demonstrate the potential of the technology by developing and characterizing a low cost micro- pump for HAN-based propellants. The goal is to develop a system with dry mass less than 1 kg (for 4 kg of propellant), less than 25 W of power, more than 0.1 N thrust, and ISP greater than 240 s. The introduction of the pump in the system allows eliminating relatively heavy valves, regulators and lines while using plastic tanks/bags for propellant storage. This reduction in system complexity and mass will allow nanosats to conduct missions with ∆V’s similar to those of today’s larger spacecraft. The pumps are based on proven recently- developed high performance gear pumps driven by DC motors and developed for small turbojets, UAV’s gasoline engines, methanol fuel cells and other applications. Also, because the power to the pump can be modulated, thrust is easily controlled and adjusted to best match mission needs.

Title:Ceramic Microthruster Clusters for Nano- and Microsatellites
Abstract:In this Small Business Innovation Research (SBIR) program, a high throughput chemical micropropulsion system for nano- and microsatellites will be developed. The microthruster will use an all- ceramic construction to withstand the high temperatures associated with the high Isp, clean burning, high-energy-density, non-toxic liquid monopropellant. The developed high throughput propulsion system will enable micro- and nano-satellites to execute precision orbital transfer and rendezvous missions, allow precision pointing of the spacecraft and its sensors, and make incremental orbital adjustments. In Phase I, modeling and simulation will be carried out to select propellant composition, i.e., oxidizer/fuel ratio, and microthruster geometry to maximize the Isp. Catalysts evaluation for decomposition of the liquid monopropellant, and materials selection for microthruster construction will be completed. Microthruster fabrication techniques will also be identified for construction and testing of a fully functional microthruster in Phase II.

Title:High Propellant Throughput Microthrusters for Next-Generation Nanosatellites
Abstract:XCOR proposes to develop a family of small propulsion systems based on small thrusters (1 to 250 N). We will address the issues such as good thrust/weight ratio at small size, low toxicity propellants, and will demonstrate an increase in performance and maneuverability for microthruster technology compared to cold gas or monopropellants. The proposed propulsion system uses self-pressurizing nitrous oxide and ethane with specific impulse approximately 265 seconds for the smaller sizes and 280 seconds for the larger sizes where the injector geometry is more favorable for good mixing. XCOR has developed a 10 N thruster that will be modified with a high expansion vacuum nozzle and partial radiative cooling for this application. The technical objectives of the Phase I program will be to show a complete propulsion system design that masses 5 kg and has a useful propellant mass fraction. A further objective is to look at the trade between thruster types for a larger, more capable, higher thrust system in the 10 kg class and do a preliminary design on the larger system by the end of Phase I.

Title:Bismuth Hall Thruster Plume Impact Study
Abstract:Because of its condensable nature Bi may cause unacceptable spacecraft contamination when used as a Hall thruster propellant. Experiments are proposed to determine the potential for bismuth deposition on spacecraft surfaces. The proposing team’s extensive experience with bismuth technology has uncovered surprising bismuth/surface interaction kinetics that will greatly complicate deposition measurements: based on evidence observed over three years of bismuth thruster operation the proposing team has discovered that the largest source of bismuth contamination during ground-testing is attributable to facility effects. A Phase I research effort is described to assess and minimize the role of facility wall interactions in ground-test measurements of bismuth deposition rates. Plume properties will be measured in a 2-kW Bi thruster via Faraday probe, RPA, and ExB probe. Deposition rates will be quantified through QCMs. Careful control techniques utilizing both an electrically biased QCM as well as a collimated QCM staring into a patented “bismuth trap” will allow identification of facility-induced deposition rates separately from those that would occur in space. A Phase II program is described for building and testing a 20-kW bismuth thruster for contamination studies on a flight-relevant device. The possibility of using a bismuth plume for defensive counter-space is considered.

Abstract:Busek Co. Inc. and Stanford University propose to develop diagnostics to characterize the plume properties and quantify contamination effects of Hall thrusters operating on condensable propellants. Phase I proof- of-concept analysis and experiments will demonstrate the ability of the proposed diagnostic techniques to accurately measure the plume. In Phase I, Busek will characterize the plume of an existing bismuth Hall thruster using Faraday and Langmuir probes, and determine whether specialized probe development is required. Busek will also design a plume contamination and erosion experiment for Phase II. In a Phase I subcontract, Stanford and Busek will design, build, and test a probe for determining sticking and scattering coefficients of neutral bismuth as a function of incident angle. In Phase II, a similar ion probe will be built and used to determine surface interaction coefficients as a function of energy and angle. Both the neutral and ion probes will be tested with the Busek thruster running Xe and Bi. In Phase II, the Bi plume and its effects on key spacecraft materials will be measured in detail. The data will enable accurate numerical plume/spacecraft interaction models and lead to a flight model thruster with T/P much greater than possible with Xe.

Title:Bismuth Hall Thruster Contamination Characterization and Mitigation
Abstract:Hall thrusters operated with bismuth propellant provide performance and cost advantages over devices operated with xenon propellant. However, bismuth propellant also has the potential to transport onto, and contaminate, spacecraft surfaces. Before the promise of bismuth thrusters can be exploited, the threat of contamination must be (1) quantified by Air Force (AF) modelers and (2) found to be mitigate-able. Before starting, the modelers require data on bismuth neutral and ion properties like condensation probability, sputter yield, charge exchange cross section, etc., as a function of energy, angle of incidence, surface material, etc. Other necessary data include the effects of bismuth film thickness on the optical properties (i.e., solar absorptivity and hemispherical emissivity) of cover glass, radiators, and Kapton blankets for example. Plasma Controls, LLC proposes to meet these AF needs through the development of robust plasma diagnostic tools that can operate in plasmas containing condensable conductive constituents. Our approach is to use an existing bismuth ion source along with existing vacuum chamber test facilities, sputter deposition tools, thin-film characterization instruments, and related support equipment of our collaborator, Colorado State University, to develop and test the proposed Plasma Controls diagnostic equipment and obtain preliminary bismuth data required by the Air Force.

Title:Materials Development for High Performance Solid Rocket Motor Cases
Abstract:Achieving increase performance with current rocket motor technology (i.e., graphite reinforced epoxy case materials) will rely on reducing the inert mass of the rocket motor case. Meeting the booster performance goals with innovative materials technologies is a much lower system level cost approach than by increasing the booster diameter or length. Higher temperature rocket motor cases resins have been identified as a technology that is capable of delivering the improved performance that next generation boosters demand. Optimizing the thermal performance of the case with resins with higher temperature capability than epoxy materials affords the designer the ability to reduce the TPS volume. The volume and mass saved by the higher operating temperature case will provide increased burn out velocity as a minimum. Additionally, replacing the inert volume with propellant will achieve even higher performance. This SBIR project will demonstrate the performance improvement of a rocket motor case using domestic graphite fibers and higher temperature resins that are currently available in the industry. Subscale rocket motor cases will be filament wound and subjected to high temperature testing to validate the translation of fiber strength in the wound construction.

Title:Materials Development for High Performance Solid Rocket Motor Cases
Abstract:Extreme elevated temperatures are reached in solid rocket motors (SRM) applications which have traditionally required the use of both interior and exterior thermal insulation materials. The development of more thermally stable composites would mitigate the need for these insulation layers. TRI/Austin is teaming with a major producer of SRM's to develop a multifunctional material approach to address this problem. Three technical objectives will be pursued simultaneously to address thermal stability issues of the entire composite system, not simply the matrix resin. By addressing the properties of both the matrix resin and the reinforcement interface, significant improvements in overall composite performance at elevated temperatures are anticipated. The next generation rocket systems will rely on technology options that provide inert component size and weight reductions. This motor design approach will enable motors to carry more propellant thereby doubling any potential benefits (less weight/more energy storage) for Future Strategic Strike ICBM designs. The proposed multifunctional material approach can improve the matrix glass transition temperature of the composite case system, while eliminating the need for traditional elastomeric insulation material system.

Title:High Frequency, High Resolution Infrared Health Management System for Rocket Engine Turbomachinery
Abstract:The success of a rocket launch depends upon the reliability of the launch vehicle, with the riskiest part being the engine’s turbomachinery. The top two life issues for turbopumps are the turbine blades and the bearings. Currently in turbopumps, there is no direct measurement of turbine blade health, and the existing methods for rolling element bearing health monitoring rely on indirect measurements, such as accelerometers and acoustic emission probes for vibratory data, and thermocouples on the bearing outer ring. As soon as a microcrack forms on a turbine blade or bearing raceway, there is an increase in heat generation due to the frictional rubbing of the crack surface. This increased heat generation is the first detectable sign of a fault. The health management system FTT is proposing would be able to detect this first indicator of damage. FTT is proposing to develop a high speed, high resolution infrared (IR) sensor for rocket engine turbomachinery health management. The improvement in health management directly supports operationally responsive space goals for turnaround time and life as well as IHPRT objectives.

The same technology technology improves safety through its ability to detect anomalies in flight and to initiate appropriate corrective action, minimizing mission impact and reducing catastrophic failures. The research provides the ability to: --Identify and assess feasibility of tools that allow health monitoring of a rocket engine turbopump. --Develop innovative system architecture integrating modeling, novel sensors, and signal processing to predict rocket engine health. --Identify data sets that can validate the tool. FTI’s approach combines expertise in the development and application of data-derived prognostic health management technology with in-depth knowledge of rocket engine turbomachinery to provide a single rocket engine health management capability for use either in flight or on the ground.

Title:Health Management Tools for Rocket Engine Turbomachinery
Abstract:Impact Technologies, in collaboration with Pratt & Whitney Rocketdyne, propose to develop and demonstrate foundational elements of an advanced Health Management system for Rocket engine turbopumps. The project team intends to build off of a best-in-class technology review and architecture/implementation trade studies to initially develop prototype diagnostic and prognostic modules for turbopump bearings that can expand to other subcomponents that pose reliability or life cycle cost concerns. The technical approach will leverage existing COTS sensor validation and advanced signal processing tools and couple them with bearing physics-of-failure models so that accurate remaining useful life estimates can be generated. While the Phase I effort will focus on ground-based Health Management tools that can be used to increase operational availability and reduce life cycle support cost for next generation Reusable Launch Vehicles (RLV), spiral development to on-board real-time capability is targeted in follow-on phases where justified. Demonstration of the developed technology will be performed in the Matlab/Simulink environment with real algorithms operating on real data sets. Furthermore, the output of the diagnostic/prognostic modules will be integrated into a maintenance reasoning concept enabling readiness certification for the next mission and providing recommendations for accelerated or delayed inspection/repair intervals to help optimize maintenance turnaround times for these critical propulsion system components.

Title:Catalyst-Free, Highly-Throttleable, Electric Propulsion Thruster
Abstract:The future of monopropellant thrusters is moving towards high performance green propellants based on hydroxyammonium nitrate (HAN) and ammonium dinitramide (ADN). Ideally, a multi mode propulsion system will include a higher specific impulse thruster for maneuvers that require propellant conservation to complement a higher thrust chemical thruster, with both thrusters utilizing the same propellant. We propose to develop an electric thruster that operates on almost any monopropellant, including hydrazine for near term missions, while maintaining high performance over a wide range of operation. The key to success is the elimination of the catalyst bed, shown to be a hindrance for both high performance (HAN, ADN) chemical thrusters and electric propulsion. Elimination of the cat bed should also increase the throttling capabilities of the electric propulsion engine. This catalyst- free thruster will also overcome thermal and life issues of the catalyst bed and allow for utilization of almost any propellant imagined. In Phase I we will demonstrate the operation of our electrically catalyzed thruster operating on a selected monopropellant. Key technologies include the liquid propellant injector and thruster starting. Pressure and temperature measurements will prove the success of our design.

Title:Microwave Electro-Thermal Thruster for Multi-Mode Propulsion System
Abstract:Physical Sciences Inc., in collaboration with our subsidiary Research Support Instruments, proposes to develop a Microwave Electro-Thermal (MET) propulsion system that can be operated using a variety of working fluids, in particular, fluids that are compatible with a chemical propulsion system and an attitude control system (ACS). Our approach is to develop a high specific-impulse microwave system, a high-thrust chemical system, and a high impulse monopropellant ACS such that when integrated together they form a high performance multi-mode propulsion (MMP) system from which individual propulsion modes can be selected on orbit depending upon mission needs. Thus, our three- mode propulsion system will uniquely provide the flexibility needed to Operationally Responsive Space (ORS) missions envisioned by the Air Force. The candidate working fluids for the MET will be energetic propellants that are also long-term storable and easy to handle. In Phase I we will demonstrate feasibility of the MET with a baseline working fluid as well as two other propellants. In Phase II, we will develop a prototype system that will be tested for propulsive performance and space environmental compatibility.

Title:Low-Cost, High-Efficiency HAN/HEHN-Based Multi-Mode Propulsion System
Abstract:Launch-on-demand satellites require both high thrust and high specific impulse (Isp). In this project, Ultramet will develop a multi-mode propulsion system that is capable of delivering an Isp of 291 seconds (density Isp of 453 s) in high-thrust mode using HAN/HEHN monopropellant. The propellant will be burned in Ultramet’s radiation- cooled oxide-iridium/rhenium (Ox-Ir/Re) combustion chambers capable of handling the ultrahigh temperature. In high-Isp mode, Busek radio frequency electrothermal thrusters will be employed after propellant decomposition in an American Pacific Corporation (AMPAC) gas generator with an Ultramet Ox-Ir/Re liner. Attitude control will be accomplished by directing generator gases to a small Busek thruster or by using small Ox-Ir/Re thrusters. Such a propulsion system will be able to accommodate many different types of orbital maneuvers, including Hohmann transfers, phase changes, and plane changes. Much of the required hardware has already been developed. Busek thrusters have been tested extensively, and Ultramet’s radiation-cooled combustion chambers have been hot-fired with O2/H2 and HAN/HEHN. The focus of the proposed project will be to further develop a HAN/HEHN catalyst and combine it into an integrated system with AMPAC’s gas generator and Ultramet’s Ox-Ir/Re combustion chamber under AMPAC’s current work.

Title:SYREN - Acoustic Resonance Igniter
Abstract:To meet the performance goals of the next generation of liquid hydrocarbon boost and upper stage rocket engines, the Air Force will require a new family of reliable and reusable igniters. ORBITEC proposes to develop and demonstrate a highly-reliable, non-toxic ignition system designed for use with LOX-hydrocarbon rocket engines, as well as other rocket engine cycle components such as pre-burners or gas generators. This ignition system will be based on a well- documented physical phenomenon known as acoustic resonance. A resonance igniter offers the promise of a reliable ignition system with no power required other than for operating the igniter propellant valves. Except for these valves, the system will have no moving parts or other external components that may be subject to failure. While some previous research activities have demonstrated the viability of a resonance igniter, no one has developed a truly functional system capable of meeting the future needs of the Air Force launch vehicles. ORBITEC proposes to take that critical next step and develop the SYREN acoustic resonance igniter to the point where it is a mature technology for boosters, upper stage engines, and other rocket engine combustion components. This proposal responds to topic AF 08-066, which requests innovations in reliable, reusable, and non-toxic ignition systems for booster and upper stage liquid rocket engines.

Title:Experimental Characterization of Particle Dynamics Within Solid Rocket Motors
Abstract:This Phase I project will evaluate the feasibility of high-speed microscopic imaging and statistical correlation velocimetry to determine the particle size and velocity in solid rocket motors. Statistical correlation velocimetry relies on obtaining an ensemble of high-speed videos of turbulent flows (both reacting and non-reacting). These videos are analyzed using a statistical correlation technique to provide full flow field velocity information. High-speed microscopic imaging is used to obtain a series of direct images of the particles. These direct images are analyzed to provide important information regarding the morphology of the particles. During the Phase I work, the feasibility of the system to will be evaluated using a segmented solid rocket motor. The diagnostic development will be completed at En’Urga Inc., The experiments will be conducted at Purdue University. Different mixes of propellants will be used so as to vary the particulate size and velocity and provide for a complete evaluation of the feasibility of the system. During the Phase II work, additional diagnostics to estimate the temperature, particulate concentrations, and gas concentrations will be added to form a novel tool for studying metalized propellants in solid rocket motors. After evaluation at Purdue University, the system will be ported to Edwards Air Force Base.

Title:Experimental Characterization of Particle Dynamics Within Solid Rocket Motors
Abstract:The development of experimental diagnostic techniques is needed for characterizing particle dynamics within solid rocket motors (SRMs) for implementation in SRM modeling codes. Development of robust, accurate computational tools for predicting flow, heat transfer, and material response within SRMs can enable significant improvements in launch vehicle performance, development, life-cycle cost, and reliability. The Department of Defense (DoD) has identified the need for experimental characterization of particle size and dynamics throughout the motor from particle creation at the propellant burn surface to nozzle exit for accurate modeling of the internal environment of next-generation SRMs. Limited data are available to describe the particle size distribution, shape, and gas/particle velocity. The approach to the problem involves 1) reviewing available data and understanding its scope and accuracy, 2) defining priorities of the experiment regarding SRM locations and design parameters and data to be collected (e.g., particle size, shape, and velocity) for these locations and design parameters, and 3) demonstrating applicability, limitations, and improvements in state-of-the-art diagnostic tools for these experiments. The diagnostic techniques must provide data that are useful for optimization of modeling and simulation tools for motor designs. This will support current and future DoD ballistic missile and space launch applications.

Title:A Low-Cost, Lightweight MTM Enhanced Conformal Antenna for GPS/Communication Systems
Abstract:This Phase I SBIR program will result in the design, simulation and construction of a prototype of a multi-band GPS/Communication system antenna. To accomplish this task, NanoSonic is staffed or has teamed with a unique combination of engineers, chemists and materials scientists capable of designing, simulating and fabricating this array. NanoSonic will consult with the USAF and a defense prime integrator for guidance and application metrics. The NanoSonic PI is antenna engineer with many years experience in both hardware implementation and simulation software construction. In Phase I NanoSonic would design a suitable antenna meeting the constraints for gain, polarization, bandwidth, scanning and physical characteristics. In the design of the antenna, NanoSonic would employ a state-of-the-art computational electromagnetics code to achieve rapid design iterations. NanoSonic would then construct structured antennas using the unique inkjet and self-assembly processes that are used to create Metal Rubber™ in combination with unique dielectric and metamaterial substrates to create a conformal antenna. These self assembled materials can be applied to severe, doubly curved surfaces without de-bonding or cracking; the inkjet process has been employed to fabricate array antennas and microstrip feeds. NanoSonic foresees integrating these processes to create highly integrated antennas and antennas in structural composites.

Title:Improvements to Sense and Avoid (SAA) Systems for Unmanned Aircraft Systems (UAS)
Abstract:In this SBIR proposal ASC is offering to develop a UAV Sense and Avoid system that will combine ASC’s existing Flash 3D video sensor with Carnegie Mellons 2D optical sensor and avoidance software. In Phase I, ASC, working with Carnegie Mellon, will collect UAV-relevant data with its existing Flash Ladar Video Camera (FLVC) and with CMU’s EO sensor. ASC will utilize this data and simulation along with and its existing FLVC designs to develop an initial system concept design of its Optical Radar Sense and Avoid Sensor for a small UAV. Incorporating our existing 3-D focal planes, ASC will fabricate, test and deliver a breadboard Ladar camera in Phase II. This system will be suitable for demonstration of collision avoidance in a heavy traffic environment. ASC designs its own focal plane readout integrated circuits (ROICs), optics, lasers and mechanical systems, and has an excellent record of system integration and commercialization. CMU has a long history of success in unmanned vehicles including its recent win at the DARPA Urban Challenge. Flash Ladar provides an innovative approach that can provide compact solutions unmatched by traditional Radar. By combining this capability with Carnegie Mellon’s collision avoidance system, we will provide a complete system solution for UAV collision avoidance.

Title:Improvements to Sense and Avoid (SAA) Systems for Unmanned Aircraft Systems (UAS)
Abstract:Current sense and avoid systems (S&A) using visible/infrared/RF sensor technology require SWAP (space, weight, and power) that far exceeds that available in mini-UAS. An aircraft of this size still represents a significant mid-air collision hazard to other aircraft operating in the same airspace. These types of UAS are frequently operated in close proximity to the ground and cultural features (buildings, towers, etc.). While the performance levels needed for these lower, slower UAS are relaxed relative to that needed for a large UAS such as a Global Hawk, the severe SWAP limitation presents a technical challenge to creating an S&A capability for this class of aircraft. Oceanit has developed a unique approach based on technology developed for the Department of Defense that will enable a reliable, low SWAP system, for S&A on mini-UAS. This effort will show the feasibility of multi-sensor discrimination hardware and techniques toward meeting the S&A requirements of a mini-UAS under 45 lbs

Title:Automated Pixel Geo-Registration for Precise Imaging
Abstract:We study the problem of sensor calibration as it might be applied to a tactical UAV system where operability and robustness are paramount. A large number of airframes and diversity of sensor types argues for an approach that is low cost (exploiting calibration targets in the field) and applicable for various sensors. The study considers various approaches to sensor calibration and measurements enabling such calibrations with the objective of not sacrificing accuracy even when only limited prior knowledge about the sensor is provided to the calibration algorithm. Calibration approaches are verified by computer simulation and the limits on accuracy for individual measurements are established using flight data from SPIRITT (or NRL or simulated scenes). A baseline calibration approach is recommended and an implementation is developed that can be carried forward into Phase II.

Title:Automated Pixel Geo-Registration for Precise Imaging
Abstract:SimWright Inc. proposes a capability to georegister objects for gimbaled hyperspectral systems in: surveillance, reconnaissance, and tracking modes while enabling targeting. The concept proposes significant georegistration error reduction between features commonly identified in multiple sensor sweeps than traditional systems by combining existing tiepoint correlation algorithms integrated with a Kalman Filter and correlated with periodic DPPDB/ NTM updates. Three trade studies will be performed 1) evaluating feasibility of adapting tie-point algorithms, and KF to perform frame to frame correlation in real-time, 2) evaluating extending the capability for georegistration across full sensor sweeps and 3) accuracy, cost and feasibility tradeoffs in system and subsystem design. The complex nature of subsystem errors in real-time gimbaled sensors requires an accurate knowledge of subsystem error components. Combining tiepoint algorithms, a particular Kalman filter, and a DPPDB/ NTM (when fielded) update capability permits engineers to diagnose system errors to create error models (e.g. platform attitude (yaw), gimbal errors). We propose a cost effective flight test for final validation of the Phase I algorithmic architecture. SimWright has a ten year heritage integrating inertial navigation systems, and developing software solutions for photogrammetry, image processing, analysis, 3D visualization and metadata creation.

Abstract:We will develop the INV-PS system for combining motion constraints, spectral properties, and spatial properties for target detection and tracking in persistent surveillance data. INV-PS will learn adaptive spectral and spatial models that can be applied to targets with a wide range of characteristics. The models will support detection and tracking in complex environments over time intervals that vary from less than a second to several days. The approach is derived to allow tracking in the presence of illumination changes, spectral mixing, occlusion, and variable target motion. In addition, INV-PS is designed to allow different sources of information to be incorporated in a principled manner. INV- PS uses efficient algorithms that support real-time processing on the sensor platform. The new models and algorithms will be assessed over a range of data. A detailed commercialization plan is given for the new software.

Title:Multi-Target Track and ID with Persistent Hyperspectral Data
Abstract:Military operations in urban warfare provide an added emphasis to effectively detect, track, and ID ground targets in challenging environments. Given the high dynamic nature of ground targets and the ambiguity that may result from closely spaced targets, incorporation of feature data from sensors such as hyperpsectral imagery (HSI) cameras provides a means to disambiguate the tracking of these targets. The benefit of using these sensors in multi-target tracking is the ability to build feature models for target tracks based on the spectral information over multiple wavelengths. The video-based tracking community has demonstrated the ability to resolve closely spaced targets by incorporating color features versus intensity data alone. The addition of 20 to 200 additional wavelengths has the potential to significantly improve a target tracker’s ability to distinguish among targets. The Phase I effort will demonstrate the ability of our algorithms to (i) simulate an urban scene and embedded targets along with models to generate sensor measurement data (ii) generate detections from HSI imagery based on a combination of motion and feature segmentation (iii) mitigate the effects of spectral smearing (iv) perform HSI feature-aided tracking of multiple targets in an urban setting using both real and simulated data.

Title:Electronic Bumper for Rotorcraft Brownout Approach and Landing
Abstract:BCO’s Phase I goal is to design an electronic bumper for rotorcraft using a rugged COTS radar module that is in production in lots of 10,000 for use on automobiles. This automotive radar is a K-Band unit with a phased-array antenna that can be stepped through 140º in azimuth and which provides 20-inch range resolution. A chain of nine of the radar modules is capable of providing the hemispheric coverage sought for the electronic bumper. The projected selling price for BCO’s electronic bumper design is well within the $10,000 target. There is a tradeoff between range and update rate. When scanning out to 80 feet the hemisphere can be scanned at up to 125 times per second. With update rates of up to 3 times per second, scanning out to 490 feet is achievable. The Principle Investigator has been designing a system for automotive-vehicle detection and testing the design with production units of the radar since March of 2007. The target detection, scene analysis and hazard identification algorithms required for the electronic bumper will build on that work. The electronic bumper design will rely heavily on retrospective detection and track initiation techniques operating on stored scene time histories.

Title:Electronic Bumper for Rotorcraft Brownout Approach and Landing
Abstract:In a number of arid regions of the world, recirculation of dust by the rotorwash of helicopters results in the loss of visual cues during helicopter approach and landing. This condition is typically referred to as brownout. This is a serious problem for all services and leads to numerous aircraft and personnel losses in Afghanistan and Iraq. The effectiveness of the conventional approach of using spotters positioned in aircraft doorways to call out and maintain clearance from obstacles has obvious limitations, especially in the most degraded visual environments. An “Electronic Bumper” system would detect and track major obstacles including other aircraft in flight during brownout and virtually all low/no visibility approach and landing. An active RF system is preferred, one operating at high-enough frequency and bandwidth to provide the needed system resolution. SNC’s electronically reconfigurable aperture (ERA) technology is ideally suited to this task. ERA is a patented electronically steerable array technology that has been demonstrated at across the range of frequencies of interest. This proposal describes a Multiple Scanning Array Radar (MSAR) that will achieve the required functionality. The hardware and processing architecture is described, along with the approach to demonstrating that the system will meet all requirements.

Title:Innovative Micro Air Vehicles & Control Techniques for Urban Environments
Abstract:Micro Aerial Vehicles (MAVs) will provide an important capability for both military and civilian uses, including reconnaissance, target identification, search and rescue, and bomb damage indication. The development of effective MAVs for these missions will require the production of a real-time autonomous flight navigation and obstacle avoidance system for operation in complex urban environments which is suitable for implementation on these small vehicles. The flight platforms will have limited payloads which will require trade-offs in computational power and sensor type, including sensor resolution and frame rate. To conduct the obstacle detection and collision avoidance Radiance proposes a MAV flight control system that utilizes appropriate sensors in real time to autonomously construct a 3-D obstacle map, which effectively encapsulates physical objects within the MAV's potential flight path, and guide the MAV along a safe trajectory that positions the MAV for successful completion of its mission objectives. The geometry building algorithms are envisioned to provide the added benefit of geometric feature extraction and detecting real-time change within the geometry to identify non-cooperative moving objects.

Title:Innovative Lightweight Onboard Aerodynamic Palliatives for Helicopter Brownout Dust Abatement
Abstract:Rotorcraft brownout, which is caused by the entrainment of dust and ground debris by the rotorwash during take-off and landing, is a critical operational problem, and has caused a significant number of military helicopter accidents in Iraq and Afghanistan. Brownout affects safe operations due to the reduction of visibility, in addition to damaging engine components and rotor blades. Recent experience gained from operations in brownout with a variety of rotorcraft configurations, as well as ongoing work with validated analyses, indicates that aerodynamic modifications to the aircraft may offer a true solution to the brownout problem, at least in terms of pilot visibility. Therefore, the effort proposed herein seeks to develop innovative lightweight onboard aerodynamic solutions to brownout that can be retrofitted to current rotorcraft and incorporated into future designs without degrading performance or requiring additional onboard equipment or consumables. This effort will leverage work for the US Army developing physics- based analysis tools for the engineering simulation of rotorcraft brownout conditions and expertise in rotorcraft aerodynamic design, testing and performance analysis, to demonstrate that lightweight active aerodynamic solutions to brownout are not only viable, but also practical and cost effective without posing a risk to performance, operations or personnel.

Title:Ionizing Brownout Mitigation System
Abstract:To address the Air Force need for airborne dust abatement to restore visual loss, called brownout, during helicopter approach and landing in dry arid regions, Physical Optics Corporation (POC) proposes to develop a new Ionizing Brownout Mitigation (IBOM) System. It is based on energy-efficient, safe, directional electromagnetic pulsation repelling dust particles from a helicopter. The IBOM omnidirectional transmitter array with its unique RF beam installed on the exterior of the helicopter bottom scatters away dust in suspension mode. The innovation in the IBOM dust outward acceleration will enable IBOM to not only provide enough energy to disperse dust particles against the recirculation force caused by rotorwash, but also to be safe and power-efficient through solid-state RF sources and beam shaping. In Phase I, POC will build a IBOM system and demonstrate the feasibility of IBOM as a proof of concept, with a full-scale Phase II system prototype. In Phase II POC plans to design/fabricate to fully functional IBOM hardware and control software optimized for minimal complexity, and to demonstrate that a TRL-4 prototype is capable of recovering visibility lost by dust recirculation in a real or simulated dust environment.

Title:Algorithm to Emulate RF Signal of Multiple Targets for Countermeasures Technique Assessment
Abstract:Long-range semi-active Surface to Air Missiles (SAM), Air-to-Air Missiles (AAM), and Air-to-Air Anti-Radiation Missiles (AA-ARM) represent a threat to US aircraft. These missile guidance systems employ monopulse antennas and receivers which are less vulnerable to conventional Electronic Attack (EA) techniques. Conventional EA techniques coupled with sophisticated angle countermeasures can increase the success of U.S. Forces counter air operations (offensive and defensive), theater missile defense, and suppression of enemy air defenses. The development and testing of EA countermeasures is very expensive. Man/hardware-in-the-loop laboratory simulation is the most cost-effective methodology for evolving/maturing advanced EA countermeasure technologies because the battlefield can be brought to the laboratory through multi-spectral synthetic battlespace simulation. Current laboratory RF threat environment simulators do not provide the required fidelity to accurately simulate the parameters needed to develop these advanced EA countermeasure techniques. DRA proposes to solve this challenging technology limitation by developing an innovative solution to control (steer) the RF signals within the Triad antenna array network (AAN) to support the advanced countermeasure development. During Phase I, DRA will develop a top level design and conduct a proof of concept demonstration of key technology element. During Phase II, DRA will develop a prototype capability and demonstrate key performance characteristics.

Title:Algorithm to Emulate RF Signal of Multiple Targets for Countermeasures Technique Assessment
Abstract:Matrix Research and Engineering will develop an optimal algorithm for producing the best possible emulation of multiple target signals using triad antenna array network. Phase I of the effort will develop and refine an initial algorithm and demonstrate it on a simple 6 element triad array. To minimize the expense of the hardware we will constrain ourselves to using only one triad per target emulated. The approach will use a least squares approach to compute the optimal setting of attenuators and phase shifters that result in the closest possible wavefront impinging on the aperture under test to the desired one based on the emulated target geometry. Various optimization schemes will be considered to minimize issues when a target transition between triad arrays. Scalability will also be addressed during Phase I. The algorithm will easily support the use of more than 3 antennas per target as well as scale to a greater number of targets emulated by a large array of networked triads. During Phase II the concept will be validated on larger triad arrays. Special attention will be taken to ensure ease of setup and use of the software during this phase of the program.

Title:Fiber-Optic RF Distribution (FORD) & Digital Control Signals Network Across a PCB in GPS User Eqpt
Abstract:High performance RF circuits found in highly robust GPS user equipment are especially sensitive to inter-board electromagnetic interference, which results in spurious signals and poor circuit–to-circuit isolation. NuWaves’ innovative solutions will be applied to designing and developing state-of-the–art miniature Fiber Optic RF Distribution (FORD) transmit and receive modules. NuWaves will investigate the use of fiber optics as a means for distributing Radio Frequency (RF) and high-speed digital control signals across a Printed Circuit Board (PCB). The use of fiber optics will be studied as a way of significantly reducing inter-board Electromagnetic Interference (EMI). During the phase I effort, NuWaves will perform cost/benefit trade-off study of fiber optic technologies taking into account size, weight, power, and cost factors. Detailed circuit modeling, simulation, hardware prototyping, and performance characterization will be accomplished to validate the FORD concepts.

Title:Ruggedized RF Photonic Networks Using Flip-Chip VCSEL Transceivers
Abstract:We will integrate RF circuitry within VCSEL-based transceivers designed to couple light into multi-mode fiber and/or printed circuit board waveguides. VCSELs offer SWAP and cost advantages over traditional modulator/edge-emitter devices by reducing power consumption, allowing for dense integration into chip-scale packages, lower cost devices and relaxed packaging tolerances. We will leverage the existing flip-chip packaging technology developed for a mil-grade 10 Gbps transceiver by replacing the digital circuitry with RF circuitry. The packaging technology includes lenses that couples all VCSEL to minimize modal noise effects, low parasitic flip-chip electrical bonds to reduce EMI, current-source VCSEL drivers for better RF linearity and potential for integrating up to 12 channels into a single package. The Phase I program will have key tasks: 1) definition of system requirements, 2) definition/prioritization of interconnect architecture in a trade-off study, 3) RF characterization of existing components, and 4) preliminary design of key circuit blocks.

Title:Two-Beam Transmit Satellite Antenna for Limited Field-of-View (FOV)
Abstract:The objective of this Phase I SBIR effort is to develop and demonstrate a low cost, low weight, two independent simultaneous transmit beam antenna for use in SATCOM systems like the Transformational Satellite Communications System (TSAT) downlink. The current MILSATCOM system supports one downlink antenna beam in the frequency band 20.2-21.2 GHz. The goal of TSAT is to transform communications so that every warfighter in the field has rapid access to information for decision-making purposes. In addition, TSAT will be required to move much more data like that associated with visible images and radar images as well as facilitate communications on the move, a feature none of the previous satellite constellations offered. In order to achieve this increased capability in the near future, the MILSATCOM capacity must be increased through the use of multi-band, multi-beam satellite antennas. The primary objective of this effort is to develop and demonstrate a simultaneous and completely independent two-beam transmit antenna that has the capability to support MILSATCOM down link.

Title:Two-Beam Transmit Satellite Antenna for Limited Field-of-View (FOV)
Abstract:Trade studies to provide two independent simultaneous transmit down- link beams for geostationary orbit MILSATCOM applications will be completed. Two direct radiating active array solutions will be analyzed. Both use a 32” x 32” array aperture as required for 1 degree half power beamwidth with approximately 450 elements arranged in a triangular array element lattice to minimize the number of components needed. Both utilize a novel method for obtaining maximum EIRP, acceptable SSPA noise power ratio and power added efficiency. One solution utilizes a beamformer comprised of 2D Rotman lens stack for frequency independent simultaneous beam formation. The approximately 300 lens beam ports are selected by a 2 x 300 beam RF switch. A second solution utilizes a beamformer comprised of a 2 x 450 corporate fed active phased array. Each active element will have two independent phase shifters to enable the simultaneous independent beam formation. Two array fed reflector configurations will be also analyzed. Corporate feed array with two phase shifters/variable attenuators per element and confocal lens stack fed configurations will be considered. Two non- array fed reflector configurations will be analyzed. Analysis trades for performance, cost, weight, power, isolation, and coupling will be performed. Spatial intermodulation effects will be calculated.

Title:Advanced Modeling and Control for Aeroservoelastic Design
Abstract:It is well-understood that actuator nonlinearities, such as free-play, can induce limit cycle oscillations (LCO) in otherwise stable closed-loop systems. In flight control systems, free-play specifications are often set conservatively in order to preclude free-play-induced LCO. However, conservative free-play requirements can increase the manufacturing cost of actuators and give rise to a costly program of regular inspections. An analytical method to safely relax free-play limits could significantly reduce actuator manufacturing and lifecycle costs. Importantly, in addition to accurate aeroelastic modeling to predict LCO, proven adaptive control methods exist to mitigate the effects of uncertain actuator nonlinearities, such as free-play. Thus, maximum benefit would be derived from a tool that combines accurate aeroservoelastic modeling and adaptive control to relax free-play manufacturing tolerances, mitigate the adverse closed-loop effects of actuator free-play, and adapt to changes in free-play over time. Barron Associates and its partners propose to develop an Advanced Modeling and Control for Aeroservoelastic Design (AMCAD) Toolbox to provide the Air Force with a rigorous analytical method to establish safe free- play limits for flight control surfaces. AMCAD will feature our recently- developed, computationally-efficient aeroelastic flutter prediction methodology and a proven adaptive control technique for actuator nonlinearity compensation.

Title:A System Approach using CartEuler-based Nonlinear Aeroelasticity for FP/LCO Analysis and Design of Control Surfaces
Abstract:The ZONA Team proposes to develop a nonlinear aeroelastic/aeroservoelastic methodology for free-play (FP)/LCO analysis and prediction for aircraft control surfaces at various trim conditions and subjected to gust/pilot commend excitations. In phase I, a CartEuler-based FP/LCO methodology (CEFM) will be established with a ZONA-developed Cartesian Euler solver fully integrated with a ZONA nonlinear flutter/LCO module (NLFLTR). The Cartesian grid/ boundary condition features of CartEuler allows it to perform rapid but accurate nonlinear aeroelastic simulation for complex aircraft configurations. The CEFM solutions will be validated with wind tunnel test data to be obtained by Duke University with an existing model of typical airfoil section at various FP angle and AoA under gust excitations. Next, using CEFM we will fully investigate various F-16/HT cases, including strained/unstrained structures and under gust/pilot-commend excitations for the impacts of nonlinear aerodynamic and nonlinear structural effects on each free-play and LCO responses from a 3D system perspective. Computed solutions of CEFM for the F-16/HT cases will be compared with those of ZAERO. Based on the computed CEFM results, a useful free-play scaling law will be developed that can be readily applied to establish improved control surface free-play criteria for modern aircraft.

Title:Image-based Navigation for Cloud Avoidance (INCA)
Abstract:Unmanned aerial systems (UAS) such as Global Hawk must exercise due regard for the safety of other aircraft by performing sense and avoid, providing an “equivalent level of safety”, compared to manned aircraft. However, the Air Force frequently needs to fly UAS missions covertly using emissions control procedures, precluding the use of transponder-based systems or radar for collision avoidance. Most passive sensors, however, do not have the ability to “see through” clouds and other visual obscurants, necessitating flights to remain within visual meteorological conditions (VMC). To address this need, we propose a system based on passive sensing to detect and avoid clouds, called Image-based Navigation for Cloud Avoidance (INCA). INCA performs cloud detection in either visible or long wave infrared imagery, using a combination of motion, color, and texture cues. To enable navigation, the system goes beyond simple 2D image detection, and estimates 3D range information using structure from motion. When the current flight path violates VMC minima, a path replanning algorithm based on A* uses the 3D information to compute alternate flight paths. A closed-loop evaluation framework incorporating a flight simulator tests cloud detection performance over a range of operating conditions and tests the efficacy of avoidance maneuvers.

Title:EO/IR Due Regard Capability for UAS Based on Intelligent Cloud Detection and Avoidance
Abstract:Current Unmanned Aerial Systems (UAS) flights, including the Global Hawk weapon system, face limitations on their utilization of civil airspace because they have no capability to sense-and-avoid (SAA) other air traffic. Federal Aviation Administration (FAA) Regulation states that remotely/autonomously operated aircraft must have an equivalent level of safety, comparable to see-and-avoid requirements for manned aircraft, to satisfy FAA safety requirements, and must exercise due regard for the safety of other aircraft by detecting them and maneuvering to avoid them. UtopiaCompression Corporation (UC) proposes novel algorithms (through research, development and augmenting/refining existing in house algorithms) for providing due regard using existing EO/IR sensors based on the detection of cloud and sky regions. Specifically, UC will corroborate the feasibility of (i) Segmentation of images into homogenous regions and region merging (ii) novel algorithms for extracting and selecting visual features (iii) novel algorithms for the classification of pixels and segmented regions into three classes: sky, cloud and others, and tracking the cloud regions through time. These modules and their integration with existing SAA processing chain will be designed, developed and tested in consultation with the Air Force Program Manager and SAA prime contractor, Northrop Grumman Corporation (NGC).

Title:Verification of Cold Working and Interference Levels at Fastener Holes
Abstract:The USAF recognizes that benefits to cold working fastener holes include significantly increased life of a structure subjected to fatigue loading. However, full realization of this potential from a maintenance and engineering standpoint is hindered by the fact that there is currently no adequate field technique for determining how well the material structure immediately surrounding the hole has responded to the cold working process. Thus, there is a distinct need be able to: 1. Determine the success of a cold working treatment at a fastener hole, 2. Quantify the results of the treatment in a robust crack growth and residual life analysis, 3. Monitor the evolution or relaxation of the residual stress state as usage on the component accumulates, and 4. Understand the effectiveness of the residual stress field in the presence of a crack. Our team’s approach strives to provide depot-supportable measurement of cold work residual stresses using NDI techniques currently in the USAF maintenance infrastructure. We also aim to provide the ASIP community with the life assessment tools (based on AFGROW) and criteria needed to capture the benefits of cold working in life extension and to guard against stress relaxation, the influence of cracks, and inadequate processing.

Title:Verification of Cold Working and Interference Levels at Fastener Holes
Abstract:Cold working (Cx) and interference fit fasteners are well known to effectively impart favorable residual stresses (RS) and improve structural fatigue life around fastener holes. Heretofore, there has been no reliable means of measuring the RS or the effectiveness of Cx in the immediate vicinity of fastener holes, so reliance was placed on Cx process controls. In addition, the effects of various levels of Cx on remaining fatigue life have not been quantified. Accordingly, design credit for Cx is seldom taken and its favorable effects are not accounted for in structural fatigue life analyses. The Proto Team solution to this problem has two elements: A portable NDI/E system for quantitatively measuring in a production environment the levels of RS imparted by Cx and a reliable life prediction methodology that can exploit the output surface RS data. Proto has recent experience using advanced x-ray diffraction (XRD) technology to nondestructively measure RS fields around Cx holes and will demonstrate that capability concurrently during fatigue cycling of a representative coupon set with Fatigue Technology Inc. UDRI will introduce the RS/fatigue cycling data into finite element analyses and current life prediction models and correlate the life prediction output with fatigue test results.

Title:Design/Life Prediction Tools for Aircraft Structural Components with Engineered Residual Stresses
Abstract:Hill Engineering is committed to the development and application of engineered residual stress, which is the intentional use of residual stress treatments coupled with sound engineering analysis to improve the performance of metallic structure. Hill Engineering’s experience with recent aerospace programs has highlighted the need and opportunity to develop analytical engineering approaches (and tools) that can robustly and efficiently take advantage of the potential benefits of residual stress treatments. The goal of the present work is to perform a proof of concept demonstration of a design tool for fatigue assessment of surface treated airframe structural components. Key tasks include the prediction of residual stress and fatigue performance (durability and damage tolerance) in surface treated fatigue coupons, which represent the geometry of an important F-22 structural member. Experiments (residual stress measurements and fatigue tests) will be performed to validate the predictions. This proof of concept work will leverage existing Hill Engineering design tools and on-site experimental capabilities in residual stress measurement and fatigue testing.

Title:Life Prediction Tools with Engineered Residual Stresses
Abstract:The Air Force has identified a need for the development of predictive design tools that can be used to accurately determine the fatigue life of components containing both applied and engineered residual stresses and determine the optimal location and processing parameters for residual stress introduction. Impact Technologies, in collaboration with Third Wave Systems, and Fracture Analysis Consultants, propose to develop an integrated analysis tool that will achieve this objective. The technical approach is based on integrating design capabilities for 3D modeling for residual stress prediction, 3D computational fracture mechanics, and life prediction calculations. The approach will also take into consideration statistical variants due to modeling accuracy, loading conditions, and material behavior. This integrated approach will allow for the identification of component high stress/life-limiting regions, determination of engineered residual stress process application regions, computation of damage tolerance effects due to different residual stress inducing processes, and the determination of relative cost benefit per flight hour gained due to each processing method considered.

Title:Resource Relationship Management for Defensive Counterspace (RRM4DCS)
Abstract:Effective defensive counterspace (DCS) begins with the ability to maintain space situational awareness (SSA). The detection and discrimination of spacecraft events has moved from low-level alarms, to the application of data fusion (DF) across multiple levels, and most recently, to the use of resource management (RM) to complement data fusion and translate operational requirements into responses for satellites, ground stations, and links to warfighters. There are severe complexities in managing a large number of resources supporting several concurrent missions across commands. To assist JSpOC operators with Level 2 Resource Management, we propose to design and demonstrate the feasibility of decision-aids and automated algorithms for Resource Relationship Management for Defensive Counterspace (RRM4DCS). Our approach is founded on the Dual Node Network (DNN) Data Fusion & Resource Management (DF&RM) architecture and extends our current research in Level 2 and Level 3 data fusion as a member of the AFRL/RV Data Fusion Research Team to Level 2 resource management within the JSARS program. Our proposed approach features the formulation of a resource relationships ontology, an analysis of alternatives of optimization approaches, the design of a level 2 RM node network, and refinement of existing Level 2 Data Fusion to support resource relationships management. BENEFIT: These decision-aids and automated algorithms developed under this effort will enable operators to reduce the time required for generating responses and increase the quality of appropriate response actions for defensive counterspace operations. We see direct application of the proposed effort to the JSpOC via the JSpOC Situational Assessment

Title:Distributed Satellite Resource Management for Defensive Counterspace
Abstract:The objective of this effort is to tightly couple automated SSA assessment and DCS response decision aids to provide prioritized response alternatives to assist space operators to manage competing objectives, coordinate responses, and rapidly prioritize response alternatives within dynamic environments. The DF&NN team will develop the threat scenario data using new intelligence data sources, extend the JSARS SSA capability, analyze response management alternatives, and then design and develop an interacting combination of situation assessment and response management algorithms for an automated closed-loop DF&RM feasibility experiment. We propose new data sources and response resources to drive improved SAFIRE coordinated data fusion and response decision aids with SSA/DCS Battlespace Visualization Initiative (BVI) visualization capabilities that will support the JSpOC and space squadron operators. The sensor data is planned to be obtained through an experimental MTSI-related program that links BMDS COMNET to AFSPC, from AFSPC/A9, from the Space Catalog, and from the Blue and Red space order of battle (SOB). The DF&NN team will provide MTSI Subject Matter Experts (SME) personnel to help define plausible and relevant scenarios that will highlight SAFIRE envisioned operational utility and define the appropriate concept of operations (CONOPS).

Title:Optical Transmitter for Inter-satellite Communications
Abstract:For many communication applications the demand for more bandwidth is a never ending problem. Military system applications often can exceed commercial demands by an order of magnitude or more as SIGINT and IMINT data collection and transmission are keys to our National Security. Fiber optic systems using optical carriers have been demonstrated up to 160Gbps and RF modulation at over 100GHz has been demonstrated as well. In communication applications where the system must maximize dynamic range, the use of modulators with low modulator drive voltage can provide many benefits. Typical optical transmitters currently employed consist of a discrete DFB laser module followed by a discrete LiNbO3 Mach-Zehnder modulator. This configuration is often too bulky for applications where size, weight, and power trade-offs are of primary concern. What is needed for these applications are high speed optical transmitters that are compact monolithically integrated chips. Archcom’s proposal is to monolithically integrate its state of the art InP-based DFB laser technology with its InP-based multiple quantum well p-i-n 50GHz modulator technology. The monolithically integrated chip will achieve bandwidths in excess of 50GHz, modulator drive voltages less than 2V for extinction ratios of 10dB, and output optical powers of 30mW.

Title:Passively Deployed Lightweight Solar Array Structure for Thinned-Multijunction Solar Cells
Abstract:Current deployable solar array systems are based on designs that have been in existence for more than 30 years. In general, these heritage designs can be divided into two classes: 1) hinged-panel arrays, which are mechanically simple but mass inefficient, and 2) tensioned- membrane arrays, which are mechanically complex but mass efficient. Arguably, no deployable solar array designs exist that are both mechanically simple and mass efficient. Furthermore, the largest heritage systems (i.e., tensioned-membrane arrays) are limited to less than 15 kW of total power and 50 W/kg of specific power. Higher power generation capability (i.e., greater than 50 kW) with efficient packaging (i.e., greater than 250 W/kg) is becoming an important requirement for many future Air Force missions. GaAs-based multi-junction solar cells can now be thinned (below 20 microns-thick) in order to produce flexible solar cells of the same efficiency as current, much thicker, state-of-the-art rigid solar cells. If these thinned cells are integrated onto next-generation, ultra-lightweight, deployable solar array structures that exploit the novel design characteristics of the cells, 6 fold improvements to the specific power (>500W/kg) of space deployable solar arrays can be attained in the near term for systems up to 100kW in size. Thin, flexible-cell arrays offer a potential solution to the above challenges, as they are capable of more compactly stowing for launch, while having a lower mass than traditional arrays. Unfortunately, the benefits attained by populating array structures derived from heritage deployable technologies with these thin, flexible-cells are not sufficient. In order to achieve the desired power output and specific power goals for next-generation solar power systems, lightweight solar array

Title:Lightweight Solar Array Structure for Thin Multijunction Solar Cells
Abstract:Future military and commercial spacecraft missions are driving the need for power generation systems that can provide extremely high specific power (W/kg), ultra-low stowage volume (kW/m3), extremely high power capability, high reliability, and affordability. Current state-of-the- art optimized solar arrays rely on heavy composite honeycomb structures and are approaching performance plateaus (~100W/kg and ~13kW/m3). The recent technology development of high-efficiency ultra-thin multijunction solar cells (~20um thickness) with projected 33% efficiency allows for a dramatic optimization of the deployable solar array structural system. Ultra-thin multijunction solar cells when combined with an appropriately optimized deployable structure promises to produce a solar array system that provides specific power in excess of 500 W/kg and stowed packaging efficiency greater than 40 kW/m3. The proposed Phase 1 effort will establish concept feasibility of an innovative tensioned membrane solar array system structure and increase its technology readiness level for future development efforts. The tensioned membrane solar array system provides significant performance improvements over current state-of-the-art solar array technologies and enables future mission applications. BENEFIT: The proposed Tensioned Membrane solar array promises to provide high specific power, compact stowage volume, high reliability, and affordability when compared to current state-of-the-art systems. The discriminating performance will enable future missions. The proposed technology has the potential to ultimately replace existing solar array systems currently used for most Military, civilian, and commercial applications. The total solar array system market is estimated at $500M

Title:Laser Hardened Coatings for Advanced Satellite Solar Cell Arrays
Abstract:Currently deployed defense space systems are hardened against naturally occurring environmental radiation. Man-made radiation threats such as lasers and other directed energy weapons pose a different danger entirely. Solar cell arrays can be disabled or damaged during a high power directed energy attack. In the proposed Phase I program, Infoscitex will characterize the damage mechanism to advanced solar cell arrays and evaluate active responsive thin film materials for threat reduction. The active response will reduce damage at the initial attack site and effectively increase survivability of the surrounding cells, dramatically reducing propagation of damage. The materials-based countermeasures will not require external power, respond almost instantaneously and have minimal impact on solar cell efficiency. In the Phase II effort, it is envisioned that different generations of optimized systems will be tested on actual solar cell systems to evaluate survivability after a simulated attack. Qualified DoD platform vendors, coating materials and solar cell arrays will be active participants in both the Phase I and Phase II programs to ensure incorporation of the technology into deployable systems.

Title:“Strength Through Curvature” Enabled Optimization of Advanced Solar Array Structures for Future Thinned Multi-Junction Solar Cells
Abstract:This proposal is targeted at advancing solar array performance metrics (particularly specific power) by providing a novel and innovative support structure for future thinned, multijunction crystalline solar cells. Leveraging its “Strength Through Curvature” expertise, Mevicon, teamed with ATK-Space Systems Goleta, proposes an array architecture derived from ATK’s space-qualified UltraFlex architecture. In particular, we propose the investigation of the use of induced curvature to stiffen UltraFlex substrate gores populated with thinned multijunction cells. The curvature-stiffened blankets will allow the previously required membrane tensioning preload to be reduced/minimized, which should, in turn, enable a significant reduction in the support structure mass, yielding further improvements in the UltraFlex’s already impressive performance metrics. In the PI, we propose to perform more detailed system-level feasibility studies, develop detailed component-level analysis of substrate material selection and curvature designs, perform critical path proof-of-concept experimental tests to confirm predicted behavior, and finish with a detailed point design. This prepares the way for a PII focused on protoflight hardware development and the subsequent PII/PIII transition to flight demonstration opportunities. The likelihood of this transition occurring is increased by the teaming with ATK in this Phase I effort.

Title:Maneuvering boosting missile tracking using agile filters
Abstract:Recently Russia has tested several times an improved version of an ICBM (Topol and Topol-M) that are said to be able to penetrate any missile defense system. The proposal addresses the threat posed by such advanced Russian missile technology. The proposed effort is then addressing an extension of the monocular passive ranging (MPR) technique to space based sensors. If MPR from space is accurate enough, it would allow a single space tracking system to fix 3D position of boosting threat like the Topol missiles and establish a track file on such targets. Early fix and track file shortens the CBMC2 timeline and improves the kill probability of the target. The proposed capability could negate the measures that the advanced Topol missile may be using during boost phase to avoid BPI. Passive ranging over the entire boost stage requires spectral techniques that work from the troposphere, through the stratosphere, mesosphere, and into the thermosphere during day and night and under various background and target scenarios. Agile filters may provide the required MPR capability. The proposed investigation will assess the feasibility and accuracy and develop a CONOPS for boost phase maneuvering target track file development. Range retrieval will use a combination of target models such as SPURC / CHARM along with atmospheric RT model such as SAMM that consider high altitude LTE and NLTE, combined with OKSI's ASCOPE technique for solving inverse problems.

Title:Novel Mitigation Techniques for Reconfigurable Computers for Space Based Applications
Abstract:Reconfigurable systems popularity for space-based applications has grown considerably due to their flexibility and the ability to multiplex in real time different hardware configurations based on the demand of the system application. Commercial FPGA based designs are susceptible to Single Event Upsets (SEUs) caused by radiated charged particles. This is primarily due to the use of a commercial SRAM based FPGA. The traditional approach for Single Event Upset (SEU) mitigation on commercial parts consists of triple modular redundancy (TMR). Although proven effective this method adds a certain amount of logic overhead and a penalty in power consumption and processing speed. A more recent approach - called “scrubbing” - relies on simply reloading the configuration memory frames at defined time intervals. This approach is possible in the case of FPGA devices that support partial reconfiguration, such as the Xilinx Virtex II, Spartan 3, Virtex 2-Pro, Virtex 4 and Virtex 5. We propose to investigate all previously enumerated considerations and alternatives to determine the best SEU mitigation technique. In Phase I of the effort, we will explore different scrubbing methods and define the scrubbing circuitry capabilities based on the architecture’s characteristics. This phase will also comprise the investigation of scrubbing rates required in this architecture for a number of representative applications. It will also provide us with the tools and framework to evaluate in the same way different reconfigurable computer architectures. BENEFIT: If a Phase II and Phase III options are exercised for this proposal the AFRL and other DoD systems will have access to a component that will reliably allow the use of commercial FPGAs for space applications.

Title:Novel Mitigation Techniques for Reconfigurable Computers for Space Based Applications
Abstract:Demand for high performance On-Board Processing (OBP) for space- based applications is being driven by the advancement of high speed sensors, downlink rates that are orders of magnitudes less than sensor data rates, and the desire for autonomous real-time operations. ReConfigurable Computers (RCC) based on Field Programmable Gate Arrays (FPGAs) are an excellent candidate for high performance processing, but they are susceptible to Single Event Upsets (SEUs). Traditional mitigation techniques such as triplication of code coupled with majority voting, designated as Triple Modular Redundancy (TMR), have proven effective in mitigating SEU effects for RCC systems. However, these methods come at a premium in Size, Weight, and Power (SWaP) and performance. For computationally-intensive systems with multiple gigabit data rates, these techniques while feasible might not be practical for the space environment where SWaP is a premium. To address the need for SEU mitigation while minimizing the impact to SWaP, novel mitigation techniques will need to be employed to fully capture the benefits of space based RCC processing systems.

Title:Novel Mitigation Techniques for Reconfigurable Computers for Space Based Applications
Abstract:The use of FPGAs in space applications is well understood, but there has always been the need to have an ability to reprogram such devices in the field. Until now, this was not possible without a great deal of risk due to rad effects, or a tremendous amount of additional circuitry to mitigate any rad effects. By applying the innovative TTMR and H-Core approaches, this SBIR will show how reprogrammable FPGAs can be used in a specific application, high-speed image processing, in a way that provides greater throughput than similar designs could achieve.

Title:An Advanced Cryocooler for Space-Borne Applications
Abstract:Future Department of Defense (DoD) space electro-optical payloads will require reliable, efficient, and lightweight cryocoolers for sensor cooling. Turbo-Brayton cryocoolers are an ideal candidate for these payloads. The technology is reliable and space proven with one unit having provided over 5.5 years of successful operations on the Hubble Space Telescope without any change in performance. Recent advances in component technologies have dramatically reduced the mass and increased the efficiency of turbo-Brayton cryocoolers. Current turbo-Brayton cryocoolers are comparable in mass and efficiency with competing cryocooler technologies at modest loads and higher, and they have the inherent integration benefits of negligible vibration emittance and the ability to cool distributed loads and loads distant from the heat rejection site. The net result of these benefits is significant reductions in overall payload mass. During this multi-phase program, we will develop a turbo-Brayton cryocooler for a specific DoD mission. During Phase I, we will perform trade studies and develop a preliminary design of the cryocooler. The results will be presented at a preliminary design review and will provide payload integrators with critical data for system level trades.

Title:Low Cost Space Cryocooler System for Launch and Boost Phase Sensor Applications
Abstract:Future space based systems will require cryogenic subsystems that are substantially more efficient than those presently in use. Projected requirements for space-based launch and boost phase detection and tracking sensors are 10 W in the 70-110 K range and 20 W in the 160- 180 K range. The cryogenic cooling system must also be low in exported vibration so as not to impact unacceptably large jitter to the sensor. The traditional approach is to meet these objectives with a large, two-stage cryocooler coupled to complex control electronics that provide the necessary two-stage temperature control and, in the case of a linear cryocooler, exported vibration control. The South Bay Science and Technology Corporation, as the prime contractor, and Raytheon, as subcontractor, propose to develop a an alternate cryogenic system concept utilizing all low cost space-qualified elements to yield a Low Cost Space Cryocooler System for space-based launch and boost phase detection and tracking sensor applications. The work plan is structured to lead into the subsequent hardware phase.

Title:Collaborative Analysis Simulation Tools for Space Surveillance Network (CAST4SSN)
Abstract:With the increased high interest of the U.S. Air Force in developing the decision assistance tools that can optimize, layer, network, and allow cooperation of the distributed airborne sensors in the space domain and its operations, there is a fundamental need for increased level of automation, coordination and intelligent collaboration among various physical agents in the current and future battlespace to produce a common understanding of readiness of resources and real-time status. One of the major concerns of this system development is the evolution from human intervention to machine autonomy/intelligence. Many technologies regarding standalone unit operation are well developed and tested. AGNC proposes the Collaborative Analysis Simulation Tools for Space Surveillance Network (CAST4SSN) for this task cooperation problem. The objective of this project is to establish a working hardware/software integration framework in order to enable a higher- level collaborative control and command over the task orientation architecture under minimal human supervision. AGNC proposes to develop the innovative CAST4SSN which encompasses collaborative tasking decentralized subsystems, task assignment and mission planning algorithms, as well as Human Machine Interface (HMI) and is future standard compliant for external Information Technology (IT) infrastructure expansion to complete a hierarchical command chain.

Title:Game Theoretic Multi-agent Modeling and Analysis Framework for Distributed Collaborative Systems with Aid of Data Mining and Data Fusion
Abstract:We propose a highly innovative modeling and analysis framework for distributed collaborative systems with aid of data-mining and data-fusion concept. Our approach has two major highly coupled parts: 1) Data fusion module. Mutliple-sensor data are fused to perform situation awareness. To generate the intent inference of the targets, we will extend Markov games via incorporating Multi-Cumulant Pareto Nash strategies and Graph concept. From a perspective of distributed decision making problem, we dynamically adapt Hierarchical Task Network and Auction algorithm for optimal meta-task decomposition and assignment. A collaborative search and tracking oriented sensor management algorithm based on Pursuit-Evasion game will be exploited to improve the performance of the multi-layered sensing system. 2) Data-mining module. Adaptation and pattern/feature recognition are carried out to dynamically select (or mine) appropriate features or feature sets and quickly associate them with the adversary intent and executable actions. In some time-critical scenarios, firstly, a primitive adversary intent estimation and the associated friendly force collaborative response actions can be quickly provided by the Data- mining module. Then, a refinement based on data-fusion will be carried out to improve the performance of the decision aids tool. Additionally, we will incorporate a semantic and textual processing technique to convert meta-tasks into actionable fusion processes BENEFIT: The proposed game theoretic decision aid tool for cooperative system modeling, simulation, and analysis has tremendous applications potential in many military applications. It can also be directly used for developing of advanced mission planning and emergency preparedness decision

Title:Secure Active Global Radio Frequency Identification (RFID) System.
Abstract:This proposal describes in detail the requirement for secure RFID tracking utilizing a “real-time” system to pinpoint the actual location of military assets. Current technologies/systems are passive and limited to scanning or reading from direct contact or very short range and do not support critical supply chain management with rapid movement of supplies and equipment during a wartime scenario. The technical objectives of this SBIR proposal include the design and verification of a functional long range, secure and reliable Radio Frequency Identification material inventory management system. PES will utilize its expertise and its ADAPTMESH system to develop optimum systems. PES will focus on Time Sync. Mesh Protocol (TSMP) that has a zero collision rate. PES and its associates are patented in lithium battery and ultra capacity and are developing optimum power packs including prismatic cells, a 200 Wh/kg prismatic battery with novel lithium nickelate, and developing new primary missile batteries for MDA. Integration will be proven by computer modeling in a lab environment with precision GPS coordinates. The system will be compatible with the current and next generation of military signal capabilities including Y-Code M-Code. Furthermore, the powering characteristics will allow for Selective Availability/Anti- Spoofing Module (SAASM) receiver usage. Also, powering hardware will be deployed with coatings that deter analysis of their internal operation.

Title:Highly Secure Active, Satellite-enabled RFID System with Sensor Capability
Abstract:The proposed Phase I research will prove the feasibility of developing a secure, satellite-enabled, radio frequency identification (RFID) system for verifying the location of and tracking in-transit items without disclosing the location or nature of the communications to unintended individuals. SecureRF’s breakthrough cryptographic protocol, the Algebraic Eraser™, is the world’s first linear-based security algorithm that is small enough to fit on resource constrained devices. The anticipated result of Phase 1 is to determine the feasibility of implementing this protocol within an active RFID tag with GPS functions to authenticate the incoming satellite signal’s request, take the tag from a dormant state to quickly encrypt and transmit the tag’s location along with protected data on the tag and then return it to a dormant state. Implementing cryptography directly on RFID tags is a significant innovation as current security standards cannot address this need. SecureRF will develop the cryptographic model and show how it can be combined with current mature technologies to create a private, secure, active, global RFID system with sensors. The research team includes a leading RFID engineer and world-class cryptographers. In Phase II, a prototype of this system will be designed, developed and produced for field testing.

Title:REmote Monitoring and Operational Test Evalution Stimulator (REMOTES)
Abstract:Current Automated Test Equipment (ATE) often results in erroneous fault detection due to anomalies not foreseen by ATE engineers. NST proposes an innovative remote testing capability to stimulate, capture, monitor, and distribute SUT avionics data to/from FOL logistics centers to/from a remote body of SUT experts (SPO, Intermediate Level, Prime Vendor). The innovative approach utilizes network centric communications, an Automated Test Mark-up Language (ATML) extension for logistics, SUT specific XML data dictionaries with published schemas, a publish/subscribe data server to distribute the data dictionaries and SUT data to remote clients, COTS hardware, and NST’s REmote Monitoring and Operational Test Evaluation Stimulator (REMOTES) software to provide remote Mil-Std-1553 and ARINC testing capability. One or more SUT experts, at various remote locations, can be immersed within the test environment to monitor the SUT performance using any COTS java-enabled platform as well as inject test stimuli. With remote testing capability, many false positive fault detections may be isolated and possibly repaired at the field level and returned to service at a significant cost savings.

Title:Development of Cad Plating Replacement with Alkaline Zinc-Nickel Electroplating for Threaded Fasteners/Components
Abstract:Aircraft structure and propeller systems utilize both high and low strength steel, cad plated threaded components and fasteners throughout its structure. Threaded joints and fasteners manufactured from these alloys require sacrificial protective coatings due to the corrosive environment. Cadmium (Cd) has been the baseline coating for such threaded joints and fasteners for many years due to its many desirable functional qualities. In addition to be corrosion protection, cadmium also provide excellent lubricity characteristics; however, cadmium is a toxic metal and known carcinogen that poses environmental and occupational safety and health risks throughout the life cycle of the plated parts. In Phase I of this project, ES3 will investigate cadmium plating alternatives; specifically, the original Dipsol Low Hydrogen Embrittlement alkaline Zn-Ni coating IZ-C17 and its latest derivative IZ-250Y, and conduct the feasibility study and testing necessary for USAF aircraft and propeller system usage by studying torque tension relationships and hydrogen embrittlement. Additionally, production features, such as tank chemistry, and barrel/rack plating techniques will be researched for utilization in a DoD depot or commercial production environment.

Title:Development of Cad Plating Replacement with Alkaline Zinc-Nickel Electroplating for Threaded Fasteners/Components
Abstract:This proposal outlines a brush plating-specific advanced technology development program that would complement a recently awarded SERDP-funded Cd Replacement effort to be undertaken by Integran Technologies Inc., a company affiliated with the present applicants. The objective of the SERDP program is to develop a nanocrystalline Zn- based Cd replacement plating process that relies upon low hydrogen evolution and optimization of the pulse plating parameters in order to eliminate issues associated with embrittlement of high strength steel substrates, consistent with the objectives of this Air Force program. The goal of the present SBIR project proposed herein would be to complement the more fundamental on-going chemistry and plating process developments of the SERDP program with a project focused specifically upon brush plating issues in particular. As an example, one primary technical thrust of the SERDP effort will be the exploration of the pulse waveform shape optimization for complete elimination of hydrogen i.e. the utilization of pulse-reverse plating in order to “lift” hydrogen off from the fastener/component surface. Unfortunately, pulse-reverse plating may be incompatible with the non-consumable anodes commonly utilized in brush plating, thereby necessitating the development of a novel Zn-based plating technique that is embrittlement- free yet compatible with existing cadmium brush plating infrastructure.

Abstract:The development of affordable, high performance hearing protection and communication systems is critical for USAF and DOD aircraft maintainers who must work in the vicinity of jet exhaust noise during launch and recovery operations. Aegisound is in a unique position to leverage recently completed first-generation ANR hearing protector designs, intended for operation in JSF noise fields, to investigate further design improvements for affordability and even higher performance. This Phase I proposal addresses a range of performance issues for the use of ANR earplugs in harsh noise environments. Earplug design, controller design, and actuator design all play vital roles in high noise attenuation. Speech intelligibility and resistance to electromagnetic interference are also included as critical system requirements. All of these components and design criteria will be evaluated for performance versus their respective roles toward affordability. During the Phase I program, all relevant design and production issues will be identified and summarized with respect to affordable procurement of hearing protection systems that are useful in 150 dB noise environments. A detailed analysis of design metrics, production alternatives, cost drivers, and a plan for deployment of the proposed solutions will be provided at the conclusion of this work.

Title:Affordable High-Performance Hearing Protection/Communication System
Abstract:Hearing protection which targets the airborne vibrations traditionally associated with hearing has advanced considerably in the last two decades. Airborne noise can be blocked or reduced to the point where the limiting factor in the intensity of sound experienced by a subject is now in large part determined by the sound conducted through bone in the anatomy of the head and face. Air Force flight personnel and other military personnel are in considerable need of advanced hearing protection, which necessarily would provide protection beyond this bone conduction limit. While there remains room for improvement in traditional hearing protection, both active and passive, a considerably larger gain in nearer terms can be realized by turning our attention to bone-coupled noise. Infoscitex is a leading innovative engineering firm and proposes a device that attenuates bone-coupled vibrations. This device is designed to work with traditional hearing protection to result in a complete system for hearing protection and communication that provides hearing protection beyond the bone conduction limit. Our plan includes the proof of feasibility of this device, as well as complete system design and partnering for manufacture and delivery.

Title:High-Performance Hearing Protection and Communication
Abstract:To address this Air Force need for high-performance hearing protection/communication for use in very high noise levels (up to 150 dB) military fighter aircraft environments, Physical Optics Corporation (POC) proposes to develop a new High-Performance Hearing Protection (HIPHEP) system based on our proprietary high-output and -fidelity direct energy conversion driver (>130 dB SPL output), and an adaptive active noise controller (average 45 dB attenuation), providing a total attenuation of at least 50 dB and up to 75 dB NRR including passive absorption effects. The HIPHEP innovations -- a microsize smart material actuator as an earplug driver -- produces >130 dB high-quality acoustic output with unprecedented flat frequency response, even below 100 Hz, with POC’s complete active noise controller. The HIPHEP on a compact DSP board, consumes <10 mA, enough for more than 16 hr in operations, with POC’s low-frequency pressure suppression MEMS for enhanced communication intelligibility. In Phase I POC will conduct HIPHEP technology design/fabrication/experiments to demonstrate system performance suitable for military environments up to 150 dB and EMI fields up to 200 V/m with risk reduction and cost analysis. In Phase II POC will design, fabricate, and deliver ten affordable (<$1200/unit) HIPHEP protection/communication systems.

Abstract:Research Support Instruments, Inc. (RSI), with the help of Westone, Inc., proposes to develop the Micro-Actuator Speaker System 2 (MASS- 2): an active noise reduction (ANR) based hearing protection system for carrier deck environments. The core of MASS-2 will be a high- intensity version of the existing MASS microspeaker/microphone array developed at RSI for AFRL. RSI will develop a microfabricated device that can address the needs of higher sound levels (~150 dB) present on the flight deck. As part of the MASS-2 technology, an ANR algorithm will be developed to allow certain desirable noises and filter the others; RSI has patented a blind deconvolution technique called self- deconvolving data restoration algorithm, or SeDDaRA (US Patent 6,8595,64) that can be applied here. The Phase I MASS-2 program will involve design, fabrication, and test of a new configuration of the RSI microspeakers for higher sound output/sensitivity, developing an algorithm for active noise reduction/fitration, and characterization of the devices to predict their performance in an aircraft carrier application.

Abstract:The traditional methods of manufacturing non-structural aerospace components require significant amounts of recurring and non-recurring costs, in addition to delays because of tooling and fixture fabrication, as well as, material availability. A large number of non-structural components for aircraft, such as clips, brackets, and ducting are presently being produced using traditional metal and plastic forming methods. Traditionally, metals have been the material of choice due to their capability to withstand higher service temperatures than previously capable with non-traditional manufacturing methods. With advances in materials and processes used for direct part manufacturing (DPM), the opportunity now exists to develop the right process and material(s) for transitioning many of the non-structural aircraft parts to DPM. With its expertise in traditional manufacturing and rapid prototyping to support manufacturing, Prototype Productions, Inc. will investigate and prove the feasibility of applying current DPM processes with select available materials, to produce non-structural aircraft parts that will meet the applicable mil-spec requirements.

Title:Locus of Control and Decision Making Among US Army Aviators
Abstract:Previous research has shown Locus of Control, the sense of being able to directly influence outcomes, can be used to predict a broad range of behaviors, including the actions taken by pilots in potentially hazardous situations. The objective of this Phase I effort is to develop and validate a prototype set of measures for assessing Locus of Control in Army Aviators. To accomplish this objective, we will review data from Army accident files and interview Aviators to identify frequently encountered hazardous situations. We will construct scales to measure Locus of Control and risk orientation among Army Aviators, and will construct a scale, modeled on the Hunter Hazardous Events Scale for use in the validation of these new scales. These new scales, along with established measures, such as the Aviation Safety Locus of Control scale, will then be administered to a large sample of Army Aviators, in a web-based format. The results will be analyzed to establish the psychometric characteristics of the new scales. The web-based data collection and validation of the prototype scales will provide the foundation for the development of an operational on-line survey and data management tool for assessment and tracking of Locus of Control during Phase II.

Title:Fostering Leadership for Ethical Climate-Setting (FLEC-S)
Abstract:In modern warfare, Soldiers frequently encounter situations that require sound ethical judgment. Recently there has been an increase in the situations where Soldiers have display unethical behavior in the face of trying circumstances. Given this, it is imperative that an ethical climate is established to guide Soldiers’ judgments and actions. To meet this need, Aptima will develop a training program designed to teach Army leaders to create an ethical climate within their units, identify and react to threats to their unit’s ethical standards, and provide leaders with the ability to practice and reinforce their climate using these skills. This project will develop a model of ethical unit climate-setting behaviors, study the appropriate training techniques to maximize knowledge transfer and skills retention, and work toward the development of a training demonstration. When complete, the Fostering Leadership for Ethical Climate-Setting (FLEC-S) training module will serve as a self-contained, self-paced training system designed to teach Army leaders to set, maintain, and reinforce an ethical climate in their units and teams.

Title:Instructional Tools for Training Programs
Abstract:We propose to develop Instructional Tools for Training Programs (ITTP), a web-based toolkit whose ultimate goal is to help instructors and training designers accomplish more effective training by providing them a resource with which to apply principles and techniques from the science of learning, in the course of designing, evaluating, and refining a training program. In pursuit of this goal, we will integrate research on: (1) the cognitive issues underlying the requirements associated with the effective design of training systems; (2) how such systems can best diagnose and help remediate trainee progress; and, (3) the technological underpinnings associated with the implementation of such systems so as to track learner progress. We will take advantage of the scientific base consisting of research in psychology, instructional science, and cognitive engineering, to understand and develop distributed, computer-based instructional tools that are tailored to not only support trainer’s understanding of the learning sciences, but also to help them understand how to diagnose trainee progress. For the design and development of the ITTP toolkit we will leverage our capabilities in the cognitive and learning sciences, training system development, and simulation technology, to help produce tools to optimize learning.

Title:Intelligent Noise Artifact Parallel Analysis Reduction
Abstract:To address the Army need for a real-time suite of noise/artifact algorithms for cognitive and physiological status monitoring (CPSM), Physical Optics Corporation (POC) proposes to develop a new Intelligent Noise Artifacts Parallel Analysis Reduction (INAPAR) system. This proposed system is based on POC’s hybrid-coupled noise/artifact separation techniques to decouple and remove not only EM noise, but also biological motion artifacts, from sensor data even at near-zero SNR conditions. The innovation in the two-layered, selective denoising architecture will enable the INAPAR system to eliminate in real time nonstationary, nonlinear, cluttered electrobiological noise. In Phase I, POC will demonstrate the INAPAR artifact/noise reduction performance boundaries under realistic test conditions, including analysis of sensors and noise artifact sources and accuracy. In Phase II, POC plans to develop a prototype system for integration with Army physiological/cognitive monitoring hardware and software and test the prototype in field trials.

Title:Sensor Artifact and Noise Reduction Algorithms for Cognitive and Physiological Status Monitoring
Abstract:Measuring and tracking the physiological and cognitive status of Command, Control, and Intelligence (C2I) system operators will provide useful diagnostic Test and Evaluation (T&E) data and reduce the risk of test failures or accidents. For example, a system that can diagnose and detect fatigue or overload can provide off-line data for gauging system effectiveness, or on-line advisories that increase test safety. However, a critical barrier to the operational deployment of such monitoring systems is the excessive loss of data arising from artifacts recorded by the various physiological sensors. These artifacts can be attributed to external interfering sources, additional physiologic signals (e.g. muscle action) or are related to significant subject motion. Typically 30 to 70% of sensor data collected during performance of active T&E tasks are still severely compromised after processing. The overall objective of this project is to develop and test the feasibility of an integrated, intelligent processing system to reduce the effect of artifacts when monitoring the physiological and cognitive states of C2I operators during T&E operations. The system will use advanced sensors and intelligent software to maximize the quality of sensor data, and provide these data in a real-time format suitable for assessing the effectiveness of T&E operations.

Title:A Model Based Simulation of Effect of Complex Terrain in Network Performance Using Efficient Ray Tracing
Abstract:Intelligent Automation Inc. (IAI) proposes a model based simulation approach to simulate the effect of complex terrain, radio transmission, and interference in network performance. The main technical difficulty in developing such a simulation environment is the complex computational tasks that each node needs to take in order to simulate the physical layer. Therefore, unless we statistically model: 1- the effect of complex terrain and its changes in the channel impulse response (CIR), 2- the effect of CIR in the bit error rate (BER) of the received signal, and 3- interference sources, then building even a small- to-medium size wireless network simulator that accurately models the physical layer is impossible.

Title:Extended Realistic Network Optimization with Terrian Fading Model
Abstract:To address the Army’s need for an accurate representation of complex terrain effects in network simulation, Physical Optics Corporation (POC) proposes to develop a new Extended Realistic Network Optimization with Terrain fading model (ERENOT) technology. This proposed software package is based on extension of existing network simulation packages such as Network Simulator (NS-2) to include terrain effects, considering higher random number cycles for realistic simulation and realistic fading models. The innovation in ERENOT will enable the system to efficiently incorporate a complex terrain model into wireless network simulation with highly accurate fading models and mobility considerations, so that a large-scale wireless/wired sensor network (or MANET) can be accurately evaluated and to provide the means to perform cross-layer optimization. In Phase I POC will demonstrate the feasibility of ERENOT by developing a model for various networked radios (software-defined radios and cognitive radios) in a simulated urban environment and validate the software package with experiments. In Phase II POC plans to develop prototype software that can demonstrate cross-layer interactions on quality- of-service metrics, which will be coded in Microsoft Visual C++ and TCL for optimal performance and will benefit native Microsoft service packages including Direct X and COM technologies.

Title:X-Wind Lidar Profiler
Abstract:A novel method of using fluctuations in laser backscatter from atmospheric aerosol concentrations to remotely measure wind speed and direction is proposed. Using pulsed laser beams projected from a small spotting telescope and range gated detectors, we are able to remotely measure 2-D or 3-D wind vectors at contiguous range intervals along a 3-km targeting range with the accuracy and resolution needed to significantly improve ballistic trajectory prediction. The technology is simple, robust, and builds on decades of development by several groups using scanning aerosol backscatter lidar. The turbulent flow of air in the lowest layers of the atmosphere insures an abundant supply of airborne aerosols to serve as tracers of atmospheric motion. Innovative SESI lidar technology turns what were previously one-of-a-kind scientific research instruments into a compact, rugged, and affordable operational wind profiling instrument suitable for military and civilian applications. SESI's Phase II instrument will be a production prototype suitable for mounting on artillery, tanks, and other ballistic gun platforms. Versions small enough to be man portable are contemplated for sniper teams. Civilian applications include airfield wind mapping on a continuous basis and wind surveys needed for developing wind energy farms.

Title:High-Power Integrated Radio Frequency (RF) Switches for Joint Tactical Radio Systems (JTRS)
Abstract:This program addresses high power RF switches for the Joint Tactical Radio System (JTRS). The use of traditional pin-diodes possesses significant limitations on the overall system performance due to the high bias current consumption in the forward biased state, relatively slow modulation speeds, vertical layout integration complications and low temperature stability. RF switches based on GaAs technology suffer from low breakdown voltage and low maximum blocking RF powers. To meet the high level requirements for various systems, Auriga Measurement Systems, assisted by M/A-COM Inc., will develop a family of RF switches based on group III nitride HFETs and specifically, insulated gate HFETs. These devices are advantageous due to their much higher power handling capability, temperature stability and high reliability for JTRS RF switches and monolithically integrated switch arrays. During Phase I, insulated gate GaN HFET switch devices will be characterized and device models will be developed. The switching performance will be simulated and compared to the device characteristics. Once the model is validated, single-pole double-throw RF switches will be designed to operate from 2-2000MHz with an insertion loss less than 0.25dB and a maximum power handling greater than 46dBm (40W).

Title:Nano-BiCMOS Night Vision Camera
Abstract:Night vision capability is one of the most important battlefield advantages of the U.S. military, especially in today’s asymmetric warfare. The Gen III night vision goggles in service today is based on the vacuum tube technology with a semiconductor photo cathode, resulting in limitations on view angle, size, manufacturing cost and device operating lifetime. The requirement of special training in combination with the minimum of $2,500 annual cost of ownership has prevented its wide-spread deployment with each and every soldier. Highly desirable is a solid state low-light-level night vision camera using the highly reliable low-cost silicon CMOS technology. We propose a nano-technology solution on the silicon CMOS platform. The proposed nano-BiCMOS low-light-level camera combines the most recently industrialized nano-materials with the miniaturized and monolithically integrated version of a proven solid-state detector technology. The resulting camera is expected to enable surveillance and reconnaissance at night vision sensitivity and large detection distances. In Phase I we will fabricate the semiconductor detector device, to prove the feasibility of our high-resolution nano-BiCMOS imager concept. In Phase II we will prototype the entire night vision camera system to full specifications, which will be delivered to DoD Labs for evaluation and demonstration.

Title:Megapixel Low Light Level Complementary Metal-Oxide Semiconductor (CMOS) Imager for Persistent Surveillance
Abstract:Continuous improvements in solid state imaging have led to various approaches to meet the combined demands of large format, low noise and high speed requirements. Novel CMOS technology provides the basis for a monolithic CMOS Imaging Sensor (CIS) that meet these demanding requirements. Powered by a multi-billion dollar consumer market, where performance requirements can be as equally demanding as military applications in terms of pixel size, power and sensitivity, this CIS technology is advancing at an accelerated pace. Customizations to CIS design parameters make it possible to meet the performance requirements for very large area dawn to dusk imaging conditions at an affordable price. With new CIS technology breakthroughs and system-on-chip integration the large format CIS will provide a low power, high speed, high performance, affordable imaging solution for persistent surveillance and other military applications.

Title:Megapixel Low Light Level Complementary Metal-Oxide Semiconductor (CMOS) Imager for Persistent Surveillance
Abstract:Persistent surveillance missions require the continuous observation of roadways, road junctions, and other areas of interest from platforms operating at low, medium, and high altitude. A single, monolithic CMOS sensor would provide significant advantages in terms of reduced complexity, size, weight, and power. Recent advances in silicon based CMOS technology have shown the potential for operation during extremely low light conditions with both high frame rate and spectral response into the NIR. The technical objectives for this project include: a) a large area, monolithic CMOS focal plane of at least 10K x 10K pixels with potential to expand to 20K x 20K pixels; b) pixel size of 5-10 microns; c) frame rate of 2 – 20 Hertz with sub-array readout capability of not less than 30 Hertz; d) low noise architecture for dawn to dusk operation; e) provision for color and black & white imagery; and f) capable of being manufactured using 200 mm wafer processes. The proposed Phase I study will address the design of a CMOS imager meeting these specifications.

Title:Remote Acoustic Signatures Analyzer for Sealed Container Inspection
Abstract:To address the U.S. Army need for a noncontact long-standoff inspection system with the capability to identify the interior fills of a sealed container by detecting its acoustic signatures, Physical Optics Corporation (POC) proposes to develop a new Remote Acoustic Signatures Analyzer (RASA). This proposed RASA is based on the unique integration of a state-of-the-art acoustic excitation source, laser Doppler vibrometer (LDV), signal processing electronics, and efficient neural network (NN) software. The innovation in using a new long-range acoustic excitation source and a long-range operation LDV, combined with a newly developed NN-based acoustic signature classification algorithm, will enable the RASA to operate beyond 10 meters with a high probability of detection (>99.9%) and a low false alarm rate (<0.1%). RASA will have a compact size (14 in. x 8 in. x 8 in.) and light weight (<12 lb), and be suitable for field applications. In Phase I, POC will demonstrate the feasibility of RASA by designing and assembling a preliminary prototype based on commercial off-the-shelf components and measuring acoustic signatures from representative container fills. In Phase II, POC plans to develop an engineering prototype RASA and test it under field conditions.

Title:Ultra-low-noise Amplifier for Cryocooled SATCOM Receiver
Abstract:HYPRES has developed and demonstrated a family of novel wideband digital-RF receivers for satellite communication (SATCOM) and other radio frequency communication, signals intelligence and electronic warfare applications. The digital-RF receiver uses superconductor integrated circuits and is mounted on a cryocooler, a reliable refrigerator that achieves cryogenic temperatures of 4 K without the need for any liquid cryogens. The present project focuses on the development of an appropriate cold front-end low- noise amplifier (LNA) for an X-Band SATCOM receiver, and its integration on the same cold platform as that for the digital-RF receiver itself. Both low-power semiconductor amplifiers (based on high-electron-mobility transistors or HEMTs) and superconductor amplifiers (based on Josephson junctions and superconducting quantum inteference devices or SQUIDs) will be comparatively investigated in terms of gain, linearity, noise temperature and power dissipation. We will select and measure the performance of cold HEMT amplifiers in collaboration with researchers at the University of California, Berkeley. The target noise temperature is 5 K or less. Based on these results, an optimized prototype amplifier and receiver system will be designed during the Phase I Option, for fabrication and delivery during Phase II.

Abstract:Metamaterials are offering a whole new paradigm shift to the design of antennas, promising some amazing new features, capabilities and form factors. However, up till now many of these fantastic improvements are only available in relatively narrow bandwidths. A new metamaterial implementation is proposed that integrates the science of Ultra-wide Band (UWB) antennas with metamaterials in a unique way to obtain UWB performance. The implementation can be used to create very low profile UWB antennas. Furthermore the design can also be case to reduce the size of other antennas as well. With the integration of new dielectric and magnetic materials, a conformal low profile UWB is realizable.

Title:Ultra-Wideband, Low-Profile, Electrically-Small Antennas Utilizing Artificial Magnetic Conductors
Abstract:The proposed miniaturized antenna takes advantage of two innovations. These include the novel antenna design concept of coupled sectorial loops and a wideband artificial magnetic conductor substrate utilizing a combination of dielectric and ferromagnetic (ferrite) materials. At its lowest frequency of operation, a coupled sectorial loop antenna (CSLA) can be designed to have maximum dimensions of 0.1£fm„e0.35£fm (where £fm is the wavelength at the lowest frequency of operation) with impedance bandwidths in excess of 10:1. In this proposed work, we will take advantage of the wideband properties offered by the CSLA concept and utilize various modified miniaturized versions of this antenna as the starting point to further decrease its lowest frequency of operation (or equivalently its electrical dimensions). Moreover, we will utilize a wideband artificial magnetic conductor (AMC) substrate and a composite feeding scheme to even further reduce the lowest frequency of operation of the antenna without increasing its occupied area. This will result in an electrically small antenna with maximum dimensions of 0.05£f0„e0.15£f0 with an impedance bandwidth ranging from 300 MHz to 3.0 GHz.

Title:Innovative Low-Profile, Wideband Antennas for Radio Receivers on Mobile Air and Ground Platforms
Abstract:There is a definite need for low-profile conformal antenna designs to replace the commonly used quarter-wavelength whip antenna for wideband (covering 0.3 – 3.0 GHz) systems on Army’s airborne and ground mobile platforms. Wang Electro-Opto Corporation (WEO) has been conducting research for such antennas for 15 years, and has developed antennas that are highly promising in achieving the general requirements of this SBIR ARMY 08-011 program. WEO proposes to develop a low-profile wideband antenna by modifying its existing well-established low-profile conformal antennas having a 10:1 instantaneous bandwidth. In Phase-I WEO will seek inputs from the Army technical monitor for specific performance and physical goals. Depending on the specific requirements, one of the following three WEO antenna technologies will be applied: the Spiral-Mode Microstrip (SMM) antenna, the Slow-Wave (SW) antenna, and the Traveling- Wave (TW) antenna. A ½-scale breadboard model that can best adapt to Army’s airborne and ground mobile platforms will be designed, fabricated, and tested in Phase-I. The test results are to demonstrate antenna performance similar to that of a whip antenna, yet having an instantaneous bandwidth over 0.6 – 6.0 GHz and with a low-profile feature suitable for Army’s needs, thus its adequacy for full-scale (0.3-3.0 GHz) brassboard development in Phase-II.

Title:Embedded Training Enhancement Support Devices for Ground Soldier Systems
Abstract:An Army goal is to create a holistic system of soldiers that is better equipped, informed, protected and trained than before. Presently, there is a gap between the vision of embedded training for the Future Force Warrior and the capabilities vs. cost analysis of most training systems. Due to the cost and operational magnitude of implementing a fully embedded training system at this stage in Ground Soldier Systems development, an intermediary system is desired. The proposed program will implement the go-between system utilizing our TENOR SCORM compliant LMS to provide live, virtual and constructive training modes to mounted and dismounted soldiers. This system will interface with existing tracking technology to track participants for LIVE training exercises. We will integrate simulation software to create gaming environments for VIRTUAL training exercises. TENOR will contain 3D maps and assignable characters for CONSTRUCTIVE exercises and each of these training environments will be linked together for an integrated training solution. At the conclusion of Phase I, we will deliver a demonstration of the TENOR system delivering a training simulation via a handheld device. This demonstration would consist of the TENOR server powering 3 palmtop devices being used by 3 participants in a live training exercise.

Abstract:The purpose of this project is to provide soldiers with the capability to train anywhere at any time using his/her equipment combined with operational combat systems. We proposed to develop a solution that leverages the TRX SentinelTM Personnel Tracking and Monitoring System. The SentinelTM is able to wirelessly track the location and orientation of multiple individuals in an indoor (GPS denied) or outdoor environment. It does not require the training environment to be equipped with any sensors, communications devices, or other infrastructure. The same technology used for tracking people can be used to track position and orientation of targets as well as the individual soldier’s weapons. Combining accurate soldier and target tracking with weapon orientation and ballistics models will allow hit probabilities to be computed in training missions. Our small inertial sensors could be added to operational combat systems for training scenarios or installed permanently. The SentinelTM System has a modular design and open architecture to facilitate interoperability with existing systems. Local user interfaces for individual soldiers, which enable sharing of the tracked position information as well as other mission critical data, will be designed and implemented under the proposed effort.

Title:High-Fidelity Runtime Database Engine
Abstract:Increased capability in natural environment data capture (such as LIDAR) is combining with expanding military requirements for embedded training and automated vehicles to dramatically increase the need for much higher resolution terrain representations and services. Previously, the most complex synthetic natural environment (SNE) representations were focused on correlation with a visual representation, but live, embedded, and automated applications will require correlation with the complexities of the real world. At the same time, embedded applications will have limited storage and processing capacity. As a result, there is a growing need for lightweight, high resolution terrain engines. Dignitas Technologies proposes an approach based upon reuse of relevant technologies combined with industry-leading SNE expertise covering Live, Constructive, and Virtual domains to investigate solutions for high-resolution, embedded terrain representations and services.

Title:High-Fidelity Runtime Terrain Database Engine
Abstract:Advances in 3D display, visualization and remote sensing technologies provide an unprecedented opportunity to achieve a “20/20” terrain representation, whose resolution would match human perceptual ability. The barriers to this revolution are the difficulties in processing high-resolution sensed-data into a Modeling & Simulation (M&S) terrain model, the lack of support for raster-based semantic data in constructive simulation terrain models, and difficulties in scaling current runtime terrain model formats to the data density required. Enhancing raster and point-cloud support in M&S terrain models will help them “track” the fidelity of the original source data. Advanced compression techniques, with a “streaming” capability for terrain users, would reduce the terrain model’s “disk footprint” and increase performance. In this project, UtopiaCompression and Lockheed Martin will team up to exploit emerging technologies to build a high-fidelity terrain engine for simulation. We will focus on investigating, designing, and prototyping an innovative pattern-driven terrain modeling and compression technology, applied to efficient runtime display, query and manipulation of high resolution terrain data for M&S services. The proposed effort will result in software tools satisfying storage, accuracy, and performance constraints to support the full-spectrum (Live, Virtual, and Constructive) of M&S while providing correlation to the real world.

Title:Simulate the Physical Response of Building Rubble at Multiple Levels of Detail
Abstract:The proposed capability will model the debris flyout and the rubble volume resulting from a munition detonation. Fidelity will be tunable so that an application can model rubble effects ranging from a low fidelity point feature with volume and dimensional attributes, to a medium fidelity areal feature with the shape and size of the rubble pile, to the highest fidelity with individual rubble pieces and their location data.

Title:Advanced Building Rubble Simulator
Abstract:Building rubble plays a major role in urban combat operations. Inability to model its effects on the environment greatly reduces a simulation’s fidelity and its training affectivity. Despite the clear need for robust rubble simulation, the state of the art in the military simulation industry fails to deliver on this problem. UtopiaCompression (UC) and Lockheed Martin Simulation, Training, and Support (LM STS) together, with UC’s extensive background in computational intelligence, computational vision, adaptive and multi- resolution 3D surface and volumetric modeling and GIS technologies and LM STS’ expertise in urban operation simulation, create a perfect team to solve this problem. Additionally, LM STS brings a technological asset; the Ultra High Resolution Building Simulator (UHRBSim). The UHRBSim’s proven ability to simulate building damage and rubble pile creation in constructive, live, and virtual simulation environments will be extensively exploited to create a novel and technologically superior rubble simulator. In this proposal, we present enhancements to the UHRBSim that will provide a robust, multi- resolution, physics based, rubble generation and flyout simulation. For Phase I, we will undertake the objectives presented in the proposal to produce a system design and an incremental implementation plan for the UHRBSim based Advanced Rubble Simulator.

Title:Compact Lightweight MAD Towing System
Abstract:Nielsen Engineering & Research (NEAR) is proposing to develop a new and innovative tow system for the AN/ASQ-233 magnetometer. The system will be small and light enough to allow its use with manned and unmanned fixed- and rotary-wing aircraft. The tow body will be stabilized to ± ½ degree in all 3 rotational axes and will minimize lateral pendulum motion over a speed range from 50 to 350 knots. Furthermore, the proposed system will not generate electrical or magnetic interference that will detrimentally affect operation of the magnetometer. Achieving all of these operational requirements in a single system is extremely difficult which makes it equally difficult to predict a priori whether or not a proposed concept will perform to the desired specifications. Thus, this proposal contains a number of innovative tow body system concepts that will be investigated during the Phase I contract. NEAR will use their expertise in numerically modeling, designing, and testing similar concepts to investigate the feasibility and merits of each and down select to one or two that will be further developed and tested during the Phase II effort.

Title:SVELTE: Lightweight MAD Sensor Towing System for UAVs and Small Helicopters
Abstract:Tethers Unlimited, Inc. (TUI) proposes to develop a small lightweight ASW magnetometer towing system in collaboration with Aerovel Coporation for integration with small aircraft and UAVs. This system will be comprised of a non-magnetic aerodynamic body for the magnetometer, a towing cable that will provide power and receive data from the sensor, and a lightweight winch for deploying and retrieving the cable and sensor. A key element of this system is TUI’s novel ‘orbital winch’ technology, which eliminates the need to use electrical slip rings to enable power and communications to be provided to the remote sensor head, thereby minimizing the mass, complexity, and cost of the overall system. In addition, we propose to integrate inertial sensors and active control surfaces on the towed endbody to meet the towing stability requirements. The combination of TUI’s extensive experience in systems for deployment of cables in extreme environments, along with Aerovel Corporation’s UAV and miniature aircraft technologies and expertise, will enable our team to develop a towing system that meets the program requirements with minimal technical risks.

Abstract:Applied Visions, Inc.(AVI) proposes to develop and build an interactive tracer for virtual objects (iTVO) – a tool that will provide analysts with a way to visually inspect and analyze the operation of software applications. iTVO is a software exploration environment that affords the user the ability to explore both the dynamic and static aspects of its design and functional operation using a powerful combination of 2D and 3D displays combined with an intuitive user interface. By employing the latest technology in virtual machines (VM’s), iTVO will provide analysts with the ability to capture software execution data, observe and analyze it in real-time, with the ability to freeze, backup, and restart operations without alteration of the actual application under study. Combining AVI’s extensive background in data capture, analysis and visualization, our Phase I effort will be devoted to defining the key requirements of the system, yyyy, and implementing key elements of the system for proof of concept demonstration and feasibility evaluation.

Title:Graphical Trace Object (GTO) Tool
Abstract:This SBIR project will provide the Navy with a Graphical Trace Object (GTO) Tool, which will generate effective and efficient visualizations of distributed applications from real-time trace data. Our goal is to successfully visualize a running distributed application, allowing the end-user to understand what the application is doing at any given moment, where problems are occurring, and whether the application deviates from its original design. Our Phase I research will extend techniques used in currently available tools by incorporating recent visualization research into the use of UML diagrams and other static visualization techniques in real time (i.e., making the static diagrams dynamic). In Phase II we will develop a prototype of the tool (i.e., a Beta version) for evaluation use in military testbeds and commercial enterprises; based on feedback from Navy evaluation and analysis of the effectiveness of our visualization techniques, Phase II will result in a working tool fully releasable to military customers. Phase III will consist of 1) sales to commercial customers capable of using the tool off the shelf (based on standard SBIR intellectual property rights), and 2) follow-on funding from military and commercial transition customers to enhance the tool and/or tailor it to their desired specifications.

Title:Graphical Trace Object (GTO) Tool
Abstract:Development and maintenance of large software systems is a daunting task. A number of tools for simplifying the development process have been designed over the years. These include source-code browsers, debuggers, and profilers. However, despite all of these tools, software has become increasingly complex and bloated, and often exhibits poor performance despite exponential increases in processor speed. We believe that this is due to developers lacking a deep understanding of how their software operates, and that tools that are able to visualize complex software operations will help them gain key insights. We propose to explore the range of techniques that are necessary for building a tool for run-time visualization of objects and object interactions in C++ programs and to investigate the practical feasibility of these techniques. The research will span multiple areas of computer science touching on data visualization, user interfaces, run-time program monitoring, and static analysis. If the option is exercised, we propose to develop early prototypes for the techniques that show the best promise.

Title:Thin-Film, Ceramic Thermocouple Sensors Fabricated by Enhanced Plasma Deposition and Shadow-Mask Patterning
Abstract:The U.S. Navy is interested in the development of non-intrusive, low- profile, conformal-coated sensors on critical components for in-situ measurement of temperature, pressure, and strain on static (e.g., vane) and rotating (e.g., blades, disk, or blisk) components in turbine engines. Ideally these thin-film sensors would operate and survive in the harsh operating environments of the engine, which induces vibration, thermal- cycling, oxidation, corrosion, and sand-erosion conditions. Engineered Coatings, Inc. (ECI) with our team member Southwest Research Institute (SwRI), propose to demonstrate an enhanced plasma deposition method to deposit a nanostructured multilayer (ML) ceramic sensor/dielectric coating system for temperature measurement under high heat-flux conditions. Initially the ML sensor system will be deposited onto Ni-alloy coupons for measurement of adhesion/toughness, residual stress, and thermal cycling / oxidation resistance to verify ML integrity. A preliminary Materials and Process specification will be developed for the best deposition parameters and materials. A cost/benefit analysis and technology integration plan will be developed. In the Option effort, SwRI will demonstrate their shadow- mask patterning technique to deposit thin-film ceramic sensor traces for thermoelectric voltage measurements. In addition, patterning of a complex-curvature component (e.g., engine blade) with the thin-film sensor will be demonstrated in the Option Program.

Title:A Thin Film Passive Wireless Temperature Sensor
Abstract:This program will develop a thin film passive wireless temperature sensor that will: 1)Measure the surface temperature of the Thermal Barrier Coated (TBC) turbine blades in the hot section of the gas turbine engine 2)Measure temperature at specific locations in the flow path and on the surface of the combustor liner to determine both radial and circumferential temperature variations. Thin film passive wireless sensors will be arrayed with other like temperature sensors in an annular ring around the combustor to determine pattern factor to sense the uniformity of combustion downstream from the fuel injectors. 3)Measure heat flux through thermal barrier coatings by pairing the proposed wireless temperature sensor (for the surface temperature measurement of TBC’s) with a similar wireless temperature sensor being developed by Wireless Sensor Technologies. That temperature sensor is designed to be formed directly on a superalloy blade and measure the surface temperature at that point. The combination of that sensor and the one proposed for development under this SBIR program will allow the measurement of heat flux through the TBC.

Title:Total Envelope Modeling Application for Transport Aircraft
Abstract:As the military increasingly relies on the militarization of commercial items, the need to assess these items in the military operational environment is key. This is particularly important in the use of commercial transport aircraft, where operational demands greatly differ between civil and military use. The use of simulation is of crucial importance, both as a method to identify operational and engineering performance, as well as familiarizing pilots with the aircraft characteristics. Unfortunately, the reliance on commercially certified training simulations, with their focus on civilian operational training, do not satisfy the assessment and training requirements for a military vehicle. In order to address the modeling deficiencies for transport aircraft, Bihrle Applied Research (BAR) proposes the development of a new “Total Envelope Modeling Application for Transport Aircraft” (TEMATA) program. The TEMATA effort will integrate recently developed modeling methodology with newly developed test and computational approaches to establish a validated modeling process for the development of high fidelity transport aircraft simulations. Further, the effort will investigate and apply novel methods of deploying these enhanced flight models in both engineering and training applications – from desktop simulation and analysis platforms to integrating the models on novel motion based simulation and in flight simulation applications

Title:Innovative Techniques of Modeling and Simulation for Commercial Derivative Aircraft Upset Recovery
Abstract:The National Transportation Safety Board's accident database reveals that up to 40% of all commercial aviation fatalities are due to loss of control. The military is acquiring commercial-derivative aircraft for certain missions, and will fly these aircraft more aggressively, increasing the potential for loss-of-control accidents. The main options available for obtaining aerodynamic derivatives outside the normal flight envelope include Computational Fluid Dynamics (CFD), wind tunnel testing, and flight testing. CTSi has proposed an innovative methodology to develop the needed aerodynamic database extensions by flight testing a scaled model UAV. This model replicates the dynamic response of the full-scale aircraft. New state-of-the-art methods in System Identification are used to extract the aerodynamic derivatives in upset conditions. The certified aerodynamic database is then appended using a new state-of-the-art automated procedure that guarantees a statistically-optimal blending of the multiple sources of aerodynamic data. Our method is self-contained and can be used by itself; and is also complementary to and compatible with aerodynamic data derived from CFD or wind tunnel tests.

Title:An Advanced Physics Based Model for Aircraft Upset Real Time Simulation
Abstract:Flight operations of military aircraft, including those derived from commercial transports, are subject to highly dynamic conditions over broad operational envelopes, which may be further complicated by off- design configurations caused by ballistic damage. Flight simulation, including training applications, must model the aircraft flight dynamics with high fidelity over this operational envelope, requiring extensive aerodynamic databases in current simulation approaches. A physics- based approach for flight dynamics modeling in the high angle of attack and sideslip range is proposed based on a nonlinear lifting line/ surface methodology combined with an unsteady aircraft wake model. This modeling approach has its roots in the aerodynamic modeling of rotorcraft, where dynamic stall and yawed flow conditions are routinely found, and has been recently examined for fixed-wing aircraft in post- stall (upset) conditions. The proposed approach permits real-time simulation of unsteady aerodynamic and wake phenomena. In Phase I, the nonlinear lifting line/surface and unsteady wake model will be applied to high angle aerodynamics and flight dynamics of commercial- derivative military aircraft for demonstration of an advanced aircraft upset simulation, including modeling of ballistic damage effects. This work will form the basis for development of a prototype simulation capability with reduced aerodynamic data requirements for military and commercial applications.

Title:Rotary Wing Dynamic Component Structural Life Tracking
Abstract:The aim of this project is to demonstrate the feasibility of a fatigue lifetime tracking system for critical components used in rotary aircraft platforms. By incorporating neural network anomaly detection techniques, algorithms will be developed that track specific critical components and their unique identification across different platforms and rotary aircraft in order to evaluate both new and historic flight load parameter information associated with the operation of these multiple critical components. Combining this information with Health Usage Monitoring System (HUMS) data bases, algorithms will be developed that can both predict anomalous behaviors associated with extended flight load parameters, as well as forecast “just in time” (optimal component retirement life cycles) and outline interim maintenance diagnostic decision points. The fatigue tracking system will further utilize advanced diagnostics and prognostics through the HUMS platform to improve battle readiness of the components and systems, as well as minimize maintenance costs over the life-cycle of the component. Further development will provide an advanced tool to maintenance engineers for determination of necessary diagnostic procedures and schedules for specified components and systems.

Title:Polarimetric Sensor for Airborne Platforms
Abstract:Polarimetric imaging is a form of remote sensing that measures the relative intensity of the polarized components of reflected radiation from natural sources in an uncontrolled environment. In a natural scene, the majority of photons are randomly polarized. However, polarization can be induced by reflection off planar surfaces. This is particularly useful for detecting reflection from machined (man-made) surfaces. Polarization is also induced in an object’s self-emitted (thermal) radiation. Polarization information has been demonstrated to discriminate targets/objects from camouflage and clutter. Additionally, it has been shown that partially buried land mines can be discriminated by the polarization content of their thermal self-emission. This proposal describes a unique polarimetric device that, when incorporated into an imaging camera, will produce two orthogonally polarized images and measure the complete Stokes vector from a single focal plane in wavebands spanning the visible through the long wave infrared. Furthermore, this device has no moving parts, is non-lossy, and extremely compact. We will develop and demonstrate the polarimetric imager under the Phase I contract, and incorporate it into a compact multiband camera capturing simultaneous video in the visible and infrared in Phase II.

Title:Polarimetric Sensor for Airborne Platforms
Abstract:The Navy has identified the need to enhance existing tactical reconnaissance platforms by utilizing emerging sensor technologies to support both domestic and national security operations. Situational awareness imagery has become a vital tool for locating, identifying and helping to neutralize threats. However, recent US military experience in IRAQ as well as illegal entry into the US across national borders, vividly demonstrates the need for improvements in reconnaissance imagery. One very promising enhancement is polarimetric imagery. Digital Fusion Solutions and Space Dynamics Laboratory plan to integrate a polarimetric sensor into an airborne platform such as the shared reconnaissance pod (SHARP). Along with the sensor development, an overall plan for system integration is described with emphasis on image format and data exchange, as well as size, weight, and power (SWAP) considerations. To make this a cost effective solution, priority is placed on using many existing system components. The proposed solution involves replacing the current MWIR senor on the SHARP with a dual mode (MWIR/LWIR) polarimeter.

Abstract:To address the Navy need for a Commandable Mobile Anti-Submarine Warfare Sensor, Physical Optics Corporation (POC) proposes to develop a new Submarine Commandable, Integrated, Flexible (SCIF) system. It will provide the capability to connect changeable modules for in-field, mission-specific functionality modifications via our easy and robust VESTEC electrical connectors. The primary parameters of SCIF include a high-powered acoustic signal generator (175 W) for submarine simulation in naval exercises, speeds up to 20 knots using our Flipper propulsion system, and the capability to dive to >400 feet in a package matching the standard Navy “A” sonobuoy. The innovations in modular acoustic arrays, connector technology, and low-power, in- water propulsion systems will enable SCIF to fully simulate submarine signatures for naval training operations. In Phase I POC will demonstrate the feasibility of SCIF by creating demonstration systems for the Flipper propulsion system and the acoustic module, and optimizing the VESTEC connector. In Phase II POC plans to further develop SCIF to create a prototype system for water testing, which will incorporate a second-generation Flipper propulsion system, a fully integrated VESTEC connector, a modular sensor package design, a first-generation acoustic module with signal processing software, and a communication system for use in the field.

Title:Geomagnetic Reference Sensor System (GRSS) for Air Anti-Submarine Warfare (ASW)
Abstract:A principal limiter of airborne MAD systems is geomagnetic noise. The long coherence length of geomagnetic noise recommends the use of correlation processing against a reference sensor outside the search area for noise mitigation, and an air-deployed buoy-mounted geomagnetic reference sensor system (GRSS) is a convenient operational configuration. This requires small, light, expendable vector magnetometers with sensitivity comparable to the larger, more expensive intrinsic scalar magnetometers used in airborne MAD detection. Sensitivity will be primarily limited by vertical surface motion noise and rotations of the vector magnetometer. Areté Associates and Ultra USSI propose to develop an air-deployable GRSS employing a fluxgate vector magnetometer that will meet or exceed the desired sensitivity of 10 pT per root-Hz over the MAD signal band. Surface motion noise will be minimized by isolating the magnetometer from surface wave motion with a mid-water drogue designed to attenuate mid-frequency surface wave motion, and further mitigated by correlation analysis referenced to surface and sub-surface motion sensors. Rotation noise will be mitigated by configuring the vector instrument as a virtual scalar magnetometer (VSM), employing a coordinated combination of motion compensation, advanced processing, and real-time in-sensor calibration compensation.

Various suspension systems and deployment schemes will be studied to determine the optimum configuration for this application. The performance enhancement will be validated for various geometries, search platforms, targets, geomagnetic-noise levels, and geology-noise levels.

The sensor is a miniature high- sensitivity scalar laser magnetometer derived from the ONR sponsored Miniature Broadband Laser Magnetometer (MBLM) Phase II Program. It is designed to sell for less than $3000.00 in volume production. The MBLM offers a state-of-the-art capability for measuring scalar geomagnetic fields with sensitivity better than 1.0 pT/ãHz from 0.01 Hz to 30 Hz. The MBLM design is based on four innovations: 1) Optically-driven Spin Precession (OSP) locked-oscillator He4 mode for the observation of the magnetic signals, 2) miniature helium-4 cells, 3) fiber-coupled laser pump source for optically pumping helium isotopes, and 4) miniature omni- directional sensor having full sensitivity on all headings. In Phase I, the anticipated noise sources for the geomagnetic buoy will be characterized and ancillary sensors and suspension systems will be added to the buoy to allow mitigation of motion and ocean wave noise.

Title:High Dynamic Range Sensor Simulation
Abstract:CG2 proposes a rework of several methodologies in the current work flow: • Overhaul the sensor database generation pipeline to upgrade the source texture data from eight-bit (or lower) to a minimum of 16 bits per component. Propose new methods of generating this data more effectively from available source imagery. Create or adopt new means of texture map compression to reduce bandwidth issues that would otherwise prevent this increased load of high dynamic range imagery from becoming useful with employed GPUs. Ensure that detectable modulation remains visible even at extreme magnification settings, to provide detail for high magnificaton sensors. • Strategically insert upgrades to the rendering pipeline to allow the utilization of higher dynamic range texture maps. Include new texture map decompression that works with the above compression methods. Retain “microtexture” detail to support high magnification scenarios. • Propose a new sensor effects simulation (optical blurring, temporal and fixed pattern noise, AC coupling, manual or automatic gain and level, etc.) that exceeds the current state-of-the-art eight or 16-bit fixed point data paths. • Investigate current prototype and future High Dynamic Range (HDR) display devices, and the means of interfacing to these.

Abstract:JRM Technologies proposes to develop a comprehensive set of innovations for high dynamic range (HDR) and high-fidelity (HF) advancements in real-time sensor simulation of night imaging devices like NVG, FLIR and SAR. The Phase I effort will perform design and proof-of-concept studies to address key legacy simulator limitations, specifically focusing in the following areas intended to improve the target acquisition and overall training experience for the warfighter: (1) creation of a new HDR/HF sensor-material texture database format suitable for GPU DXT real-time decompression, mip-mapping, bump- mapping and HDR factors; (2) improved satellite and RGB imagery classification algorithms and NPSI Standards for generation of sensor databases in this new HDR format. (3) advanced 16-32 bit HDR techniques for real-time signature and atmospherics rendering for EO/IR and RF sensors using the latest COTS GPU shaders, particularly focusing on plumes, light points, smokes and obscurants, and scattering; (4) advanced techniques for real-time 16-32 bit NVG and FLIR sensor effects simulation; and (5) techniques for 16-24-bit DVI port output for stimulation of HDR displays.

Title:Measurement/Control System for On-Machine Inspection and Tool Path Correction
Abstract:Current practice for machining ceramic radomes used in millimeter wave missiles relies on 20-year-old technology. The result of these antiquated processes is that the yield of machined radomes is unacceptably low and the time required to machine the parts is exceedingly long. These result because of the need for in-process part inspections that require the part to be removed from the machine tool, inspected in an inspection machine located remotely from the machine tool, and then realigned on the machine tool. This process is time- consuming and the difficulty in realigning the part in the machining fixture is such that many parts are scrapped before they are finished. Even parts that complete all of the machining steps are not guaranteed to achieve the proper dimensional tolerances. To overcome these difficulties, Creare proposes to develop a Measurement and Control System for On-Machine Inspection and Tool Path Correction for the fabrication of ceramic radomes. Our innovation combines on-machine inspection capabilities with tool path control and calibration to ensure highly accurate machining of complex ceramic part geometries and greatly improved speed of machining ceramic matrix composite radomes.

Title:Fidelity in Learning Environments for the Effectiveness of Training (FLEET)
Abstract:Live training of U.S. Navy and Marine Corps aviators is becoming increasingly constrained by the limited operational life of aircraft, geographic dispersion of personnel, and budgetary restrictions. Training professionals recognize the need for more efficient and effective training, and view simulators as a means to supplement live training at decreased costs. Though transfer from simulators to live-fly is likely to be high, the training community’s knowledge of the effects of simulator fidelity on transfer is limited. The Navy is interested in understanding which training programs can be effectively trained in static flight simulators and which require dynamic flight simulators. The Navy first needs measures of pilot performance in F/A-18 missions (e.g., measures of effectiveness and measures of performance) that are sensitive enough to detect objective performance differences invoked by varying levels of fidelity. Objective performance data collected during fidelity experiments will assist the Navy in making informed decisions about the appropriate balance between training in static and dynamic flight simulators, and training in the actual aircraft. This data can also be used to refine and validate a tool for matching F/A-18 training objectives to appropriate training device fidelity – from lower-fidelity simulators, to higher-fidelity simulators, to actual training in the aircraft.

Title:Mechanisms for Improving Fidelity and Efficacy of Centrifuge Training
Abstract:Improving the ability of ground-based simulators as a training mechanism for flight will enable faster and potentially more solid training of flight crew. With an eye to the requirements of the newest aircraft, which provide flight sensations and maneuvers previously impossible, we propose to improve centrifuge training. Specifically, we will tackle the issues of aberrant vestibular signals and of G-LOC training. Aberrant vestibular signals are caused whenever a subject moves their head in a direction other than that of the spinning centrifuge. We have developed a vestibular stimulation protocol that utilizes small amounts of current applied via skin electrodes that can simulate motion in stationary individuals. We will establish the use of this protocol to cancel the unwanted effects of a centrifuge trainer on the vestibular system. Gravity-Induced Loss of Consciousness (G-LOC) is a serious problem affecting even experienced pilots. While a well-performed anti-G straining maneuver (AGSM) can provide more protection than even a G- suit, there is no formal training metric. We will use our aeromedical and biomedical expertise to develop an unobtrusive sensor that can provide real-time feedback to the trainee as to the efficacy of their AGSM.

Title:Innovative Methods for Modeling and Simulation of Tiltrotor Aircraft
Abstract:Progress has been made in developing high fidelity rotorcraft simulation tools in support of design, operation, and flight testing. Limitations, however, exist in rotorcraft simulation validation and continued model updating in order to improve the correlation with flight tests. ART proposes to develop an advanced simulation validation and efficient model updating methodology that will significantly enhance modern rotary wing and tiltrotor aircraft modeling tools for providing life cycle simulation support. The proposed rotorcraft simulation validation and updating methodology will be state of the art and suited for physical component based modeling. The simulation validation and corresponding model updating will be carried out at both modeling component and system levels through a systematic approach. The proposed methodology will be focused on addressing the root cause of current modeling deficiencies, especially the strongly coupled rotor/airframe dynamics and their mutual aerodynamic interactions. Finally, the proposed methodology will be formulated to be suited for integration with physics-based high fidelity rotorcraft modeling and simulation programs.

Title:Automated Updates of Tiltrotor Simulations Using Experimental Data
Abstract:Aircraft research, development, and testing programs require high- fidelity simulations and aerodynamic models. However, once flight testing begins the process of updating the simulation to match flight-test results is often ad hoc, labor intensive, and costly. Recent research has been investigating data-driven methods for automated and semi- automated updating simulation databases, but this research does not address the unique challenges associated with updating tiltrotor simulations. In the proposed Phase I research, the authors will develop automated methods that (a) determine suitable complexity for a tiltrotor simulation model and (b) tune parameters in that model, including resolving identified parameters down to the component level, where possible. These methods will then be used to updating a complex tiltrotor model using simulated flight data. In Phase II, the authors will extend the tiltrotor approaches to rotorcraft in general, build a suite of database-updating tools, and use these tools to develop and update a high-fidelity tiltrotor simulation using measured flight-test data. For the proposed research, Barron Associates, Inc. has teamed with Systems Technology, Inc. (STI) and Dr. Eugene Morelli; we believe this team has unmatched expertise in rotorcraft modeling, system identification, and automated simulation updating.

Title:Next Generation Flight Simulation Aerodynamic Modeling of Rotary-Wing Aircraft
Abstract:Continuum Dynamics, Inc., has recently developed innovative, real-time physics-based models of rotary-wing aerodynamics for flight simulations that improve upon previously used math models. By directly modeling the physics of rotary-wing aerodynamics in real-time, these models provide high fidelity with minimal tuning and are straightforward to update for new aircraft. In fact, extensive validation has established the ability of these new methods to accurately predict many key aerodynamic metrics without any reliance on test data. The new models have already been incorporated into simulation and analysis software by all major U.S. rotorcraft manufacturers. The effort proposed here is to extend these models from rotor and rotor wake aerodynamics to include full aircraft aerodynamics, including the fuselage, empennage and wing, for both tiltrotors and conventional helicopters. A three-pronged effort is proposed involving, (1) expansion of existing methods to include real-time physical models of all aircraft component aerodynamics, (2) incorporation of new models into government and industry tiltrotor simulations and (3) development of an automated process for fine-tuning the models for precise recovery of flight test data. Emphasis will be on developing flexible, robust, modules easy to install across multiple simulation platforms and scalable to improve in fidelity as computer hardware improves.

Title:Repeatable Release Holdback Bar Health Monitoring System
Abstract:The Repeatable Release Holdback Bar (RRHB) is critical to the safe and effective catapult launch of carrier-based aircraft. The current RRHB is a purely mechanical device with no integral electronic health monitoring or warning capabilities. All records regarding the use of a particular RRHB must be maintained manually to guide normal maintenance and calibration activities. In between these maintenance cycles, there is no indication of whether or not the RRHB is performing within specifications. The objective of this project is to develop a durable sensor package that can be mounted on the RRHB to monitor key performance metrics such as the RRHB serial number, number of shots, release load, and reset status. These electronics will provide an indication to ship personnel as to whether or not the RRHB is performing within its specifications and whether or not maintenance is required. In Phase I, we will develop an overall system concept including specifications and interfacing of the sensor package with the RRHB and fleet personnel. We will also develop a prototype system and demonstrate the overall concept. In Phase II, the system will be integrated with a range of RRHBs and tested at full scale.

Title:Intelligent Repeatable Release Hold Back Bar (IRRHB)
Abstract:The Repeatable Release Holdback Bar (RRHB) is a device that is used to hold aircraft in place just prior to launching them with a catapult. These bars are about 3 feet in length and attach to the front landing gear and hold it to a cleat on the flight deck. Once the catapult is fired a pre- determined force is reached and the holdback bar lets go of the aircraft allowing it to be accelerated down the deck. There have been some problems in the past with these holdback bars letting-go of aircraft prematurely, caused by worn parts or a failure of the bar to be properly reset after a previous launch. The result is that the aircraft moves down the deck unexpectedly and too slowly for a successful launch. Michigan Aerospace Corporation (MAC) proposes a way to record the number of shots fired on the bar, read the force acting on it during each launch and monitor reset conditions. In doing so, money can be saved in preventative maintenance by detecting early signs of a failure. During use, the holdback bar goes through high shock loads, which MAC is well-equipped to address in the design of this new system.

Title:RRHB Health Monitor
Abstract:An existing Repeatable Release Holdback Bar (RRHB) is used on aircraft carriers to control the launch of aircraft in conjunction with a steam-powered catapult. This is a purely mechanical device with a finite lifespan; its proper operation depends entirely on manual adjustment and human optical inspection, often under foul weather, darkness, and time pressure at flight deck operation tempo, allowing significant opportunities for human error. resulting in loss of aircraft and human life. In addition, mechanical wear caused by normal usage can result in early release, with similar results. A health monitoring system capable of attaching to the existing RRHB designs will save millions by reducing the potential for human error as well as detecting impending mechanical failure which could result in premature release or failure to reset. Mide proposes an electronic RRHB health monitor as a retrofit kit to currently- existing RRHBs.

Title:Systemic Safety Improvements for Aircraft Carrier Launch Operations
Abstract:During the preparation to launch aircraft from the carrier, deck crews must work very close to the aircraft to complete their tasks. The area near the aircraft presents a dangerous area, especially for modern aircraft such as the Joint Strike Fighter, which has very powerful engines and extremely high noise levels. Creare proposes to address this problem by developing systemic safety improvements for aircraft carrier launch operations. Our goal is to develop technologies and process changes which can move these personnel out of the danger area or eliminate the positions entirely. During Phase I, we will thoroughly evaluate the launch process, and devise devices, methods, and procedures which either move the Weight Board Operator and the Jet Blast Deflector (JBDO) Operator out of the launch area or eliminate these positions entirely. During Phase I, we will also design, fabricate, and evaluate a new Weight Board design as well as a sensor network which monitors the JBD area for fouling. Phase I testing will help identify issues with possible approaches and synthesize solutions to address these issues. Phase I is intended to select the optimal approach, and Phase II will include the detailed development of a system which can be tested on a carrier.

Title:Machine-Aided Launch Configuration Monitor (MALCM) for Remote Flightdeck Operations
Abstract:Physical Sciences Inc. (PSI) proposes a Machine-Aided Launch Configuration Monitor (MALCM) system for monitoring Jet Blast Deflectors (JBDs) and establishing aircraft weight during a launch sequence, improving flightdeck safety and minimizing impact to in- service platforms. To achieve this, a combination of robust thermal imaging, custom display hardware, networked data transfer, and an intuitive graphical user interface is proposed. The solution is a novel, mil- spec-hardened, compact, and light-weight vehicle design, which optimally capitalizes on the existing JBD infrastructure and carrier flightdeck procedures, and is reconfigurable for different aircraft and various launch operations. Additionally, the MALCM architecture is expandable as the need for flight deck automation, ship-wide information networking, and manpower reduction grows. PSI will leverage its past and ongoing efforts in flightdeck simulation and automation, machine vision, and Mil-Spec ship-board networking hardware to bring the MALCM system to the fleet with minimum technical risk and maximum acceptance into carrier flight operations.

Title:Lightweight Integrally Stiffened Composite Structure
Abstract:Increased performance and reduced cost structures, is the direction many aerospace companies work toward. Our objective in Phase I is to demonstrate our automated in-situ fiber placement processing technology can provide low cost manufacturing methods with thermoplastic composites while maintaining structural integrity, increased performance and address issues such as corrosion and impact resistance. Our technology offers the ability to integrate stiffening components into the skin structure without the use of mechanical fasteners and adhesives. Instead, we will demonstrate the melt bonding attachment techniques that result in totally integrated structure. A continuous graphite fiber reinforced thermoplastic prepreg tape will be used in conjunction with our technology to demonstrate repeatable, accurate and low labor methods to produce high quality, integrally stiffened structures. The fiber placement technology allows us to overcome previous hurdles associated with building structures with prepreg material such as non conformability of the material, wrinkling and detailed geometry. There is not the need for labor intensive post processing (Autoclave) that is inherent with many other composite manufacturing methods. This technology is both versatile and robust enough to produce a variety of different part configurations in a low cost fashion while still maintaining the high quality demanded by the aerospace world.

Title:Lightweight Integrally Stiffened Composite Structure
Abstract:Aurora’s Integrally Stiffened SBCF Panel (ISSP) design and manufacturing approach is a replacement for honeycomb panels. It relies upon the unique forming capability provided by Stretch Broken Carbon Fiber (SBCF), which is unidirectional, collimated short carbon fiber filaments in a prepreg tape format. Uncured SBCF is formed through “stretching” similar to plastic forming of metal, allowing complex shapes to be easily produced at significant layup savings. However, after forming and cure, the discontinuous SBCF filaments provide almost the same strength and stiffness as conventional continuous fiber composites. SBCF forming to date is for single surface skins such as shear webs with formed stiffening beads. While significant labor savings result, these configurations are not suitable for external panels, where many honeycomb parts are used. ISSP features a double skin panel –a smooth outer, air passage skin and a beaded inner skin – to provide structural efficiency and light weight of a sandwich panel, but without a core. The ISSP manufacturing process, successfully demonstrated, produces panels in a single cure cycle. A detailed Trade Study to validate weight and cost vs. a honeycomb baseline design will be conducted in collaboration with Sikorsky and Bell to establish weight, quality and manufacturing costs trade.

Title:IM7/8552 Carbon/Epoxy Sine Wave Beam Pultrusion-Based Process Automation
Abstract:Graphite/epoxy sine wave beams are used in several production aircraft, including wings of the F-22 Raptor. These lightweight structures replace traditional flat web I-beams with an undulating web surface that greatly increases buckling resistance, resulting in thinner, lighter, more durable structures. Because of their non-planar layout, traditional hand layup / autoclave cured fabrication of sine wave beams is extremely expensive. Approaches such as automated tape layup and resin transfer molding have reduced cost somewhat, but finished sine wave beams can still easily exceed $500 to $1,000 per pound. In the current era of cost-driven performance, disruptive manufacturing technology that significantly reduces cost is required. KaZaK proposes to develop and demonstrate a pultrusion-based technology for completely automating the production of sine wave beams using IM7/8552 prepreg. Previous work at KaZaK has suggested application of similar pultrusion technology to flat web I-beams reduces cost by a minimum of 50% compared to other fabrication approaches. KaZaK will interact with Sikorsky Aircraft to select an appropriate helicopter structure, ensuring that our evolving design and manufacturing methods, in combination with use of qualified prepreg, will speed the acceptance of this paradigm-breaking manufacturing technology by the aerospace industry.

Title:Thermally Stable High Energy Lithium-Ion Batteries for Naval Aviation Applications
Abstract:Electro Energy has developed a robust high energy density and high specific energy lithium ion wafer cell that has demonstrated suitable characteristics for the development of advanced lithium ion battery chemistry. The cell in addition to being lightweight is easily manufactured and designed for implementation in both a high power and a high energy configuration. Electro Energy has demonstrated advanced electrodes which when fully integrated into the wafer cell will produce a lithium ion battery technology which will satisfy the demands placed upon Navy aircraft. This proposal provides for research and development of an advanced lithium ion battery chemistry that operates safely at a specific energy greater than 200 Wh/kg, and an energy density greater than 400 Wh/l. The key technologies for the proposed high energy battery are a superior cathode, stabilized carbon anode and a high performance ceramic separator. The research and development is expected to enable a complete battery which will demonstrate functionality and stability over a wide temperature range (-40°C to +80°C), high energy density (> 200 Wh/kg at the battery level), low self- discharge (<5% per month), good cycle life (>5,000 at 100% depth of discharge cycles), and long calendar life (>5 years service and storage life).

A stable and uniform composite nano-structure at low/high temperature application will be achieved by developing a ternary transition metal phosphates cathode material exhibiting high power density, and a novel ionic liquid electrolyte as alternative for standard LiPF6 to satisfy aircraft battery mission operational temperature requirement. Powdermet will concentrate on the production of materials, emphasis be placed upon the high production fluidizing bed and spray drying and low cost attrition milling.

Abstract:Yardney Technical Products, (YTP) proposes to develop, test and deliver high-performance Li-ion batteries capable of operation at expanded temperature range to meet the demanding requirements of naval aircraft. YTP, in collaboration with the University of Rhode Island, has been working on the development of innovative technologies that should result in durable, lightweight, Li-Ion batteries with significantly increased life performance at elevated temperatures. YTP proposes to take the innovations and concepts in this proposal (cathode type, stabilized electrolyte, binder solubility, stabilized surface coated cathodes, etc) and demonstrate that the combined enhancements will significantly improve the upper operating temperature. These improvements will also result in an ability to operate at higher voltages which, when combined with lightweight aluminum hardware, would result in significant increases in energy density and specific energy. While YTP has initially looked at some of the above areas, they have not yet been evaluated in conjunction with each other, optimized or even tested relative to the needs of naval aviation systems. YTP proposes to conduct this research as part of a Phase 1 and Phase 1 Option with the Phase 2 effort ultimately resulting in the delivery of vastly improved batteries with both traditional and iron phosphate technology.

Title:Cylindrical/Ogive Phased Array Transmitter for Jammers
Abstract:Dedicated EW Aircraft have inherent advantages in performing Jamming functions. The Aircraft is designed to provide a large space for multiple antenna arrays, prime power for amplifiers, and thermal management capability to dissipate the large amount of heat generated by multiple power supplies and amplifiers. A new challenge is to package all the functionality of an Airborne EW system in the relatively small volume of a modern tactical Aircraft or pod. Due to limited space, the packaging is further complicated by new requirements such as additional frequencies and waveforms, higher power, and multiple functions from the phased array. FIRST RF proposes to use an array of conformal wideband antennas supported by proprietary array simulation and analysis tools to ensure the success of this program. A conformal wideband array has the potential to use the empty space between the radome and antenna face and minimize the loss through the radome. FIRST RF proposes an integrated set of conformal antennas aboard a 480 gallon fuel tank for use aboard tactical aircraft. Because of the flexibility in the design and the array tools proposed, the technology is also easily adaptable for use aboard UAV’s for EW applications.

Title:Broadband Non-Planar Octave Nested Array
Abstract:To address the Navy need for a nonplanar wideband, high-power phased-array transmitter antenna, Physical Optics Corporation (POC) proposes to develop a new Broadband Nonplanar Octave Nested Array (BNONA). The proposed nonplanar BNONA is based on statistical signal processing, pattern synthesis, and wideband antenna designs. The innovation in BNONA’s structure will enable a nonplanar conformal design of a wideband antenna that follows the curvature of the vehicle and does not require a radome. In Phase I POC will demonstrate the feasibility of BNONA architecture by computer simulations, statistical analysis, and beam pattern processing. POC will also optimize the parameters that affect the efficiency of the system -- number of elements, element geometry etc. Based on the thorough analysis in Phase I, a BNONA conformal array will be fabricated in Phase II to juxtapose the simulation results against the characteristics of the demonstration prototype in the laboratory. Phase II will contain a more thorough analysis and measurements with a focus on the applicability and manufacturability of BNONA to perform as a high-power jamming antenna transmitter over a wide spectrum of 300 MHz through 40 GHz.

Title:Conformal Wideband Phased Array Transmitter for Jammers (1000-092)
Abstract:SI2 Technologies, Inc. (SI2) proposes to leverage its expertise in conformal wideband antenna arrays and metamaterial technologies to develop a high power jamming transmitter operating from UHF to Ka band. SI2’s proposed concept is to utilize its Direct Write and Laser Transfer conformal manufacturing technology and a novel wideband array based on a metamaterial. The resulting wideband, high power, low profile array transmitter will be capable of deployment on a number of DoD platforms to increase their performance capabilities. To develop the high power broadband (multi decade) jamming transmitters and accelerate transition of the technology, SI2 has teamed with a prime contractor who will provide system requirements and implementation opportunities. The Phase I program will demonstrate the performance of the wideband conformal array through state-of-the-art modeling and simulation. The follow-on Phase II program will refine the design and develop a wideband high power transmitter array prototype. Testing of the prototype will validate the simulation and the conformal array transmitter performance capabilities.

Title:Concepts for Pulse Interleaving Radar Modes
Abstract:Situational awareness in a littoral environment requires radars to not only detect and track surface vessels but also to discriminate and, if possible, perform classification. To this end multi-mode radars were developed that perform: Wide-area surface surveillance (Maritime Moving Target Indication (MMTI) for detection and tracking, High Range Resolution (HRR) for discrimination, and Inverse Synthetic Aperture Radar (ISAR) for further discrimination and possible classification. The difficulty has been in optimally allocating time and beam pointing space for accomplishing these different modes. This proposal takes advantage of state-of-the-art hardware and proposes a pulse-by-pulse mode interleave capability.

Title:Concepts for Pulse Interleaving Radar Modes
Abstract:The implementation of Sense and Avoid (S&A) capabilities on Unmanned Aircraft Systems (UAS) present a particular challenge in that sensor technologies, visible, infrared and RF, tend to require too much space, weight and power (SWAP) for these relatively small airframes, yet these craft are a great threat to other aircraft. The here proposed effort evaluates the feasibility of adding RF S&A capabilities to the littoral situation awareness requirements of a UAV radar as a cost–effective alternative to the addition of a stand-alone system.

Title:Low-Cost Processing of Aluminum-Based Nanothermites
Abstract:The proposed Phase I SBIR work is focused on development and testing of a continuous process for mixing of binary nanopowders in a micro- mixer system. The main focus will be on safe mixing of aluminum and bismuth trioxide or iron oxide nanopowders in water for their application as percussion primers or components of low energy initiators. The effectiveness of mixing in the continuous micro-mixer will be evaluated by testing the resulting mixture using impact sensitivity devices and the measurement of released energy. The effectiveness of the proposed micromixer will be also tested using non aqueous liquid system. The R&D work will be conducted using both commercially available and inexpensive aluminum nanopowders formed using proprietary IMP process. This new mixing process will be integrated with a drying device in order to effectively and safely remove water from the resulting mixture.

Title:Economical method for fabricating high-quality super-thermites
Abstract:Current techniques used to fabricate super-thermites are not cost- effective. To address this issue Physical Sciences Inc. (PSI) intends to develop a cryomilling process that is capable of achieving low-cost production of these materials through the use of micron-sized starting materials. The cryomilling process is readily scaleable, reproducible, safe, and flexible. The inherent nature of the process will eliminate and/or reduce risk of spontaneous ignition, partial oxidation of components, and contamination by milling media. Other expected benefits of the cryomilling process to be developed include producing super-thermite powders with increased exothermicity and lower ignition temperature over those currently fabricated using ultrasonically mixed nanopowders. During the Phase 1 effort PSI will produce aluminum/copper oxide super-thermite powder, characterize the powder and process, and provide a cost analysis of its manufacturing. The Phase 1 option will extend the method to produce additional super- thermite compositions including aluminum/molybdenum oxide and aluminum/bismuth oxide. The Phase II effort will demonstrate scaleability and reproducibility of the process to the kilogram/day level and further investigate the combustion characteristics of the nanocomposite powder.

Title:Fully-Dense High Performance Nanocomposite Thermite Powders
Abstract:This program will develop a low-cost technique for manufacturing nanocomposite thermite powders with performance matching or exceeding that of the currently available superthermites prepared using ultrasonication of nano metal and nano metal oxide powders. The technique to be developed will eliminate the need in starting nanopowders, which are relatively expensive, difficult to handle, and present an inherent problem of reduced active metal content. The technique to be developed in the project will utilize mechanical milling of commercially available micron-sized powders of aluminum and metal oxides and will further develop a recently proposed approach of Arrested Reactive Milling (ARM). ARM has been shown to offer a scalable process yielding an energetic powder that can be very inexpensive. However, ARM-produced powders have never been directly compared to conventional nano-energetic compositions prepared by ultrasonic mixing of starting nanopowders. In this Phase I program, comparisons of ARM produced and ultrasonicated powders with the same compositions will be made. Constant volume explosions will be used as one of the comparison tools. Sensitivities and other characteristics of different superthermite systems will also be assessed experimentally.

Title:Combined Analytical and Experimental Approaches to Rotor and Dynamic Component Stress Predictions
Abstract:Recent studies have made an attempt to couple computational structural dynamic tools with sophisticated computational fluid dynamic (CFD) solvers. The CFD approach is still at a nascent stage and discrepancies can be observed in both phase and amplitude of the predicted load. Due to the inefficiencies of the currently available aerodynamic models, load predictions will have to rely on experimentally measured aerodynamic loads. Therefore, a coupled approach involving both an analytical methodology for structural analysis and experimentally measured aerodynamic loads should be employed to predict individual component loads as well as the stress and strain field in critical locations. These results can then be utilized for damage tolerance and failure prediction of the individual components. The structural model should not only be able to capture the dynamic load experienced by components such as the pitch link, swashplate, hub or trailing edge flap but also detailed stress and strain field in each ply of the composite blade. Therefore, a validated three- dimensional analysis capability is required for structural dynamic analysis of rotor blades to make accurate load and stress predictions. For this purpose, Global Engineering and Research Technologies will improve and validate an existing in-house code.

Title:Combined Analytical and Experimental Approaches to Rotor and Dynamic Component Stress Predictions
Abstract:The objective of this proposal is to combine analytical modeling and experimental data to dramatically improve the accuracy of predictions for individual blade loads and stresses in dynamic components. The overall proposed approach can be summarized as follows: 1) a number of strain measurements are made on rotorcraft blades during flight; 2) these measurements are used to identify the aerodynamic loads applied to the blade (or identification of strains at critical locations, directly) using simplified models of the blade dynamic behavior, such as reduced order models; 3) the identified airloads (or strains) are used to predict stresses at critical locations in the blade and dynamic components using a comprehensive structural dynamic model of the rotor; and 4) the proposed procedure is validated by performing well-controlled laboratory experiments.

Title:Combined Analytical and Experimental Approaches to Rotor and Dynamic Component Stress Predictions
Abstract:The accurate prediction of rotor and dynamic component stresses remains an elusive goal. Despite major advancements in computational fluid dynamics techniques, prediction of the unsteady aerodynamic loads acting on the blades continues to be a formidable computational task, and the accuracy of these predictions remains problematic. Techno-Sciences, Inc.

This ARLAS system will exploit the CFD/CSD coupled rotorcraft analytical framework with the experimental measurements (stress, acceleration, loads, etc.) to constantly improve the analytical predictions via an integrated optimization scheme. UMD has enhanced the features of University of Maryland Advanced Rotorcraft Code (UMARC) with CFD/CSD coupled model.

Abstract:AON proposal response to SBIR Phase I Navy 08-022 “Miniature Ultra- High Capacity Data Storage (MUHCS) in support of Strike and Mission Planning” will allow to accelerate AON 1000 development. The Phase I proposal baseline (6 months) would enable AON to complete the modeling and design to replace passive components, align, and assemble the passive components and active optical devices. In addition, AON will complete the integrated electronics control board design, routing, layout, modeling, and BOM for the active optical devices (e.g. laser, spatial light modulator, shutter, beam steering mirror, and photo detector array). The Phase I proposal optional (6 months) would comlete key development tasks required for Phase II, specifically the assembly of the optimized optical module and integration with the fabricated integrated electronic control board designed during the Phase I baseline. The completion of the MUHCS Phase I funding report will detail the optimized optical module operation with the integrated electronic control board for the active optical devices to perform the same functional read/re-writable capabilities as the AON 1000 optical breadboard prototype.

Abstract:Development of disk media suitable for e-beam data recording using a modulated e-beam from a digitally gated Carbon NanoTube (CNT)emitter. Gated CNT emitters have been previously produced and tested by the Company, and a preliminary design of a Read/Write nanohead exists. The technology will lead to a Hard Disk Drive (HDD) technology with very small nanoscale marks, potentially providing many terabytes of data on a small disk drive. Mark sizes down to 5nm should eventually be possible, providing 100X the data density of magnetic drives. Substantial increases in data rates should also eventually be possible, and the large head-media separation allows the posibility of removable media. Both rewritable and archival media are planned.

Title:Disk-Compatible Multi-Layered Submicron-Holographic Data Storage
Abstract:Digital reference imagery and mapping data are being extensively used for strike and mission planning, providing precise terrain positioning knowledge to the avionic objects to avoid obstacles or generate aim points. However, the digital files of these geodata are as large as petabytes or terabytes. Ultra-high data storage capacity and fast dissemination of these geodata within military and intelligence services are critical important for successful defense operations. Currently available data storage technologies have almost reached their physical limitation on both storage capacity and access rate. This severely limits real-time performance of military operations. Based on our encouraging preliminary study of micro-holographic data storage, New Span Opto- Technology Inc. proposes herein a novel data storage technique based on multi-layered wavelength-multiplexing micro-holographic recording (MWMR) which combines the technical advantages of both holographic recording and conventional disc storage. The approach can potentially reach several terabytes with a single small disc or up to petabytes with multiple-stacked disks. The Phase I research will focus on feasibility studies of the proposed MWMR-based concept. In Phase II, we will improve the system design and build a compact MWMR drive to demonstrate the functionality through ultra-high density recording of terabytes and petabytes data.

Title:Precision High Alitude Sonobuoy Emplacement (PHASE)
Abstract:This Small Business Innovation Research (SBIR) Phase I study deals with the development of a precision sonobuoy emplacement technique that employs a reefed parachute to reduce air-launched sonobuoy time spent aloft and exposed to the effects of wind on placement accuracy . This effort will include a wind-tunnel testing to assess the fluid dynamic requirements that will determine parachute shape, design and reefing parameters. The system will use a barometric sensor that will trigger activation of the reefing system at a pre-determined low altitude, thus allowing the sonobuoy to free-fall from high altitude (20k-30k feet), minimizing unwanted position variation caused by wind-induced drift. Additionally, the study will explore techniques for computing accurate real-time on station wind vector information that will be used by the aircraft operational program to automatically compute the best sonobuoy release point to achieve the greatest sonobuoy positional accuracy.

Title:Precision High Alitude Sonobuoy Emplacement (PHASE)
Abstract:In today’s anti submarine warfare (ASW), sonobuoy emplacement is necessary for target detection and tracking as improperly placed sonobuoys can create poor localization regions. The need for placement accuracy from higher altitudes will be required as the P-8A Poseidon comes on line. Sonobuoy emplacement within historical required accuracies becomes nearly impossible when deployment occurs from high altitudes. Currently, to attain such accuracies, the P-3 must deploy sonobuoys at low altitudes. An air release point is calculated for each sonobuoy based on altitude and wind profile to achieve a desired splash point. Broadening this deployment methodology to include high altitude deployment above 20,000 ft (6100 m) would be insufficient because of the greatly increased amount of time each buoy would be airborne. Increased descent time increases error due to unknowns in the deployment environment which creates a splash point error that is too great for proper placement of deployed sonobuoys. SeaLandAire will address these issues while keeping changes to the package and production cost of the buoy to a minimum. Subsequently, added sensor systems, guidance and navigation systems, and/or other hardware must be kept simple and cost-effective to achieve the programs goals.

Title:Self-Contained, Portable Laser Bonded Mark Application and Data Capture System
Abstract:To address the Navy need for a portable handheld laser marking and scanning device to apply and capture machine-readable part identification codes, Physical Optics Corporation (POC) proposes to develop a new Handheld Laser Marker and Scanner (HLMS) device, based on integration of a laser scanner, laser marker, a user interface, and display technologies into a self-contained, easy-to-use unit. The HLMS technology will be a compact, portable laser marking system to generate, apply, read, and verify tracking marks, and apply and capture images of laser bonded, machine-readable part identification codes, including 1D and 2D Data Matrix barcodes or MIL-STD-130 UID symbols. The innovation in the 2D imager enables HLMS to recognize and process a pattern from its background image. HLMS also has I/O interfaces for data uploads, downloads, and future upgrades. It permits operation from a 100-200 mm distance to readily access line-of-sight accessible parts while improving the accuracy of laser barcode marking and reading. In Phase I, POC will demonstrate the feasibility of HLMS by assembling and testing a technology readiness level (TRL) 4 prototype. In Phase II, POC plans to advance to a TRL 5-6 prototype to demonstrate the effectiveness of the HLMS system in field use.

Title:Fleet Aircraft Strain Sensor Calibration System
Abstract:To address the Navy need for a simple method to calibrate strain sensors on in-service aircraft with the accuracy of a full-scale test rig, Physical Optics Corporation (POC) proposes to develop a new Fleet Aircraft Strain Sensor Calibration system (FASCAL), based on the simultaneous measurement of aircraft frame deflections at several locations under a static loading condition. True strain/load on the aircraft¡¦s body frame is estimated from the measured deflection and a high-fidelity structural model, and it is compared with the strain sensor readings for accurate sensor calibration. Optical deflection sensors measure linear and angular deflections of the wings, vertical tail, horizontal stabilizer, and nose of the aircraft with +/-100 microns and +/- 0.1 degree resolutions. The proposed strain sensor calibration system is configurable to any type of fleet aircraft and will require no time- intensive preparation steps or data acquisition. In Phase I, POC will demonstrate the feasibility of FASCAL by measuring structural deflections of a model of an aircraft when subjected to static loading and estimating the strain on the frames. In Phase II, POC plans to develop a full-scale FASCAL system, including signal processing and control electronics, which can be readily integrated into the Navy¡¦s aircraft maintenance facilities.

Title:Innovative Approaches to the Fabrication of Composite Rotary Wing Main Rotor Blade Spars
Abstract:Commonly, composite rotor blade spars are fabricated by hand layups or other non-optimized, not fully automated procedures. These methods are labor intensive and require many de-bulking steps, making them expensive. The results are often inconsistent due to the nature of work done by hand. In our process, continuous graphite fiber reinforced thermoset prepreg tape will be used in conjunction with our automated fiber placement technology to produce high performance composite main rotor blade spars. Since our process is automated, it provides repeatable and accurate results with less labor involvement. The use of continuous fiber reinforced prepreg tape allows us to tailor the lay-up to suit the design criteria at hand. Our automated process provides low cost effective manufacturing methods for the production of high quality composite structures.

Abstract:Triton Systems Inc., in combination with HEXCEL, Ingersoll, and a helicopter or tiltrotor airframe prime contractor, proposes to develop a novel manufacturing technique combining the formability of stretch broken carbon fiber (SBCF) with automated fiber placement to dramatically reduce costs for high performance main rotor spars. The automated fiber placement promises to virtually eliminate the principal cost of making main rotor spars, and the SBCF characteristics promise to simplify the processing required to achieve high quality spars. During the Phase I Triton will develop a demonstration spar geometry in combination with the airframe prime, and fabricate the molding tooling required for several trials. Ingersoll will perform automated fiber placement on the demonstration mandrels, and ship the laid-up components to Triton. Triton will conduct molding and curing trials to develop the process to a finished quality level commensurate with main rotor spar requirements. During the Option Phase Triton will perform detailed NDE and destructive examination of the trial spar elements fabricated in the Phase I to identify the correlation between ultrasonic characterization and composite quality. Additional automated fiber placement panels will also be fabricated using SBCF in order to provide specimens for mechanical property testing, including tension, compression, and shear.

Title:Dynamic Notching Module
Abstract:The Navy is looking to develop a method for notching out tunable frequency bands from the output of a high power wideband jammer. The notches must be synchronized with rapid frequency hopping radios, tuning within 1 KHz in less than 1 uS. The method must support at least 8 notches, each reducing power by at least 30 dB in a width ranging from 15 KHz to 10 MHz. Bedford Signals proposes to solve this problem by combining our advanced capabilities in high bandwidth digital signal processing (DSP) hardware with our extensive experience in sophisticated DSP algorithm development. Specifically, we intend to use DSP to integrate at least 8 instantly tunable open loop notch filters, with closed loop filters to remove harmonics and spurs. Study confirms that COTS components can support Navy requirements.

Title:High Power Tunable Agile Notch Filter
Abstract:To address the Navy need for an agile notch filtering system, Physical Optics Corporation (POC) proposes to develop a new High Power Tunable Agile Notch (HIPTAN) filter. This proposed device is based on a newly designed superconducting varactor MEMS capacitor which exhibits high-Q and low-loss characteristics at liquid Nitrogen temperatures. The innovation in the superconducting varactor will enable HIPTAN to quickly (<1 microsecond) change the impedance to shift the location and width of the notch filter with minimal insertion loss (<0.5 dB). By applying voltage to the device, it can change the notch location anywhere in the VHF to L-band, providing notch width from 10 kHz to 10 MHz. Using MEMS components will enable HIPTAN to be fabricated in semiconductor batch processes and operate at a temperature of 77 K. In Phase I POC will demonstrate the feasibility of HIPTAN by fabricating a single filter element and showing its capability to be dynamically adjusted. In Phase II POC plans to develop a full prototype with several filter elements working in tandem to create an agile RF notch filter for testing at government facilities and demonstration in an actual jamming system and actual CNI systems.

As a means to utilize reactive armors in shaped charge liners, high-strain-rate and equation-of-state properties of selected reactive materials will be characterized. These descriptions will be incorporated within hydrocodes such as CALE and CTH to examine methods to accelerate liners and form jets using reactive materials and penetration dynamics into targets. Phase I will select reactive material candidates, develop several scale-model shaped charge designs, and establish improvements in target perforation relative to a base-line aluminum liners. Phase II will further improve first order HSR and EOS models, refine the selection and design process, fabricate shaped charge liners at scale model size, test liners using flash x-ray coverage and assess wall-breaching capabilities.

Title:Metrology of Corrective Optics for Conformal Windows and Domes Using Scanning Low-Coherence Dual-Wavelength Interferometry
Abstract:As technology advances, there is increasing demand for higher quality optics with fewer aberrations. Aspheric optics meet these needs, but at present there are no practical commercial systems to test these lenses. This keeps the costs high and stifles the market. ASE Optics proposes to develop a non-contact metrology system capable of quantifying optical surfaces that cannot be measured using standard interferometric instruments. In 2006 we developed a technology known as scanning low-coherence dual-wavelength interferometry (SLCDI) to measure the transmitted wavefront of large hemispheric domes for the US Army. ASE will leverage this success to design a new non-contact metrology instrument capable of simultaneously measuring the internal and external surfaces of aspheric corrector optics. The successful completion of this project will yield a commercial metrology instrument for free-form optics that will have wide appeal to defense agencies as well as to the optics manufacturing industry as a whole.

Title:Programmable Adaptive Metrology for Conformal Optics Testing
Abstract:To address the Navy need for measuring optical figures on an aspheric dome and the associated corrector optics, Physical Optics Corporation (POC) proposes to develop a new programmable adaptive metrology (PAM) for aspheric, nonaxially (nonrotationally) symmetric, conformal optical surfaces. Current interferometry techniques have limitations on testing strong aspheres and optical domes. Recent efforts have extended metrology capabilities to optics with departures from a best-fit sphere of 50-100 microns. The PAM system will be capable of measuring conformal domes and optics with departures from a best-fit sphere of millimeters. In Phase I POC will demonstrate the feasibility of PAM via a subscale prototype and associated algorithms on material such as glass or fused silica. A clear path to scale the approach to larger sizes and infrared-transparent materials in Phase II will be planned. In Phase II POC will develop a prototype for robust, reliable operation in the required operational environments, and to demonstrate the capability to measure the steeper aspheres and conformal optics on infrared-transparent materials, and with sizes up to 200 x 200 mm. The final optical figure should be within 0.1 wavelength root-mean-square deviation at 633 nm over the full clear aperture of the part.

Title:Fabrication of Corrective Optics for Conformal Windows and Domes
Abstract:Freeform optics allow for greater versatility in optical design that will give the designer the ability to decrease the number of optics in an assembly lowering the amount of mass and volume required to attain the same optical properties. Currently the design and fabrication of freeform optics are costly due to the difficulties introduced with mainly the fabrication and metrology of these parts. By giving the designer realistic constraints as to what can be fabricated along with continued improvements in fabrication methods, large improvements can be gained in the properties of optical assemblies mainly due to the mass and volume advantages that are provided by the use of freeform optics. OptiPro has a unique opportunity for combining its newly developed solution for the Navy’s ogive SBIR metrology program, to its extensive knowledge of CAD/CAM and, “freeform capable” computer numerically controlled precision optical grinding and polishing products. OptiPro’s technologically advanced optical manufacturing capabilities along with a “support partnership” with the Penn State University Electro Optics Center and the University of Rochester Laboratory for Laser Energetics, gives us a very strong team and, clear path towards solving the difficult problems associated with, grinding and finishing of Conformal optics.

Title:Low Cost, Low Weight Composite Structure using Out-Of-Autoclave (OOA) Technology
Abstract:The increased use of composite materials in aircraft structures has provided airframe manufacturers with greater design flexibility for the production of large highly-loaded structural members with complex geometries. The main constraint on the ability to fabricate large composite aircraft structures is the size of the available autoclave to cure the components. The development of out-of-autoclave (OOA) materials decreases the cost of entry into composites manufacturing programs and allows new opportunities for aircraft designers. The development of new generations of out-of-autoclave materials has enabled the fabrication of large composite structures with nearly identical properties to their autoclave-cured counterparts. The goal of the Phase I Base Program is to develop processing techniques and tooling methods for state-of-the-market out-of-autoclave materials and fabricate a Demonstration Article using the developed process. Both destructive and non-destructive testing shall be performed on the Base Program Demonstration Article and an initial qualification and scalability plan shall be developed based on the resulting data. During the Phase I Option Program, processing techniques shall be developed for an emerging OOA material and those techniques shall be used to fabricate two large-scale Demonstration Articles to demonstrate the repeatability and scalability of the process.

Title:Shape Memory Polymer Bladder Tooling
Abstract:Cornerstone Research Group Inc. (CRG) proposes to demonstrate the benefits of shape memory polymer (SMP) bladder tooling for out-of- autoclave composite fabrication. CRG’s SMP bladder tooling is a cutting edge technology that reduces labor costs and manufacturing time for fabricating complex composite parts. Conventional silicone or latex bladders are not rigid enough to support composite lay-up before custom molding. Often material must be applied to the inside of a female mold first, an inflatable bladder inserted, the mold closed, and the bladder pressurized and inflated to consolidate the material against the mold surface. This process is labor intensive, can produce seams, wrinkles and bridging, and often results in inaccurate part shapes. These drawbacks have led to the theory of an inflatable bladder core used as the mandrel, but conventional bladder cores lack the structural integrity required for the composite lay-up process. SMP bladders operate both as rigid mandrels and inflatable bladder cores initially providing a rigid, durable surface for composite lay-up, then flexibility and inflatability when the part is formed against the interior of the final mold.

Title:Low Cost, Low Weight Composite Structure using Out-Of-Autoclave (OOA) Technology
Abstract:This SBIR Phase I proposal will demonstrate the manufacture of a OOA composite using infrared radiation and compaction technology, an innovative resin film, and a resin film infusion process to produce aerospace quality thermoplastic composite. A low concentration of IR absorber is blended into a resin polymer and cast as a thin film. The resin film is interleaved with a carbon fabric reinforcement and the sandwich is irradiated using focused infrared radiation while applying pressure from compaction rollers in a lamination process. The heat and pressure infuse the resin film into the fabric to produce a carbon- reinforced thermoplastic composite. The Phase I program will build the infrared irradiation and compaction roller processing unit, fabricate composite laminate and test to demonstrate aerospace grade performance vs. the autoclave benchmark. The Phase I Option will optimize processing conditions, fabricate and fully characterize the mechanical performance of the composite laminate. A software program will compute setpoints for tape placement processing of resin infusion prepreg for scaleup in Phase II. The laminate performance data and tape placement processing conditions will be used to select, design and manufacture an aircraft sub-component part in the Phase II.

Title:Low Cost, Low Weight Composite Structure using Out-Of-Autoclave (OOA) Technology
Abstract:The objective of the research is to screen lightweight composite manufacturing methods for rotorcraft airframes that are lower cost than the autoclave curing process. The suitability and durability of materials used for rotorcraft airframe parts must be established by approved tests to ensure the strength and other properties are applicable to the specific structure's loads and environments. TRI/Austin will conduct screening tests on composite materials to evaluate new material systems under worst-case operational environments and loading conditions. These results will be used for future analysis of rotorcraft airframe designs, with emphasis being placed on Boeing's V-22 airframe. This test program will be designed to help identify the most promising new material systems while keeping testing to a minimum. The screening test matrix will involve key static tests that will provide sufficient data to assess mean values of stiffness and strength at the extreme operational conditions. Screening will consist of tensile, compression, shear, water absorption, chemical resistance, and fatigue tests. The results from these tests will be used to verify the performance of the composite material and to augment the design and analysis of future composite airframe structures.

Title:Low Cost, Light Weight Composite Structures Using the Quickstep Manufacturing Process Technology (PVCI-001)
Abstract:Carbon fiber composite structures provide light weight and high performance solutions for military aircraft. Alternative Out-of-Autoclave (OOA) processes are needed to reduce manufacturing costs of composite structures and increase their usage for aerospace systems. Quickstep is a low cost alternative to autoclave processing, which uses large capacity fluid storage tanks and heat transfer fluids to directly heat the part and tooling and control temperature during processing, Quickstep can use either aerospace grade qualified prepreg materials or non-impregnated materials that are resin infused. The tool and part are encased to create a floating pressure equilibrium environment eliminating the need for tooling backing structures. A program is proposed to demonstrate low cost, lightweight composite structures using the Quickstep process as an alternative to autoclave processing for Navy system applications. In Phase I, sub-scale test articles will be fabricated using Quickstep and autoclave processes and tests conducted to demonstrate equivalent properties but lower cost of Quickstep. The Phase I option will study tooling materials and fabricate sub-element articles. In Phase II, Vector along with Boeing and the Navy will identify full-scale test articles to be fabricated and tested using the Quickstep process technology.

Title:Biodynamic and Cognitive Impact of Long Duration Wear of the JSF Helmet Mounted Display During Normal Flight Operations
Abstract:Unites States Navy, United States Air Force, and European Air Force have documented neck injury rates of 50% or higher ranging from minor neck strain to cervical vertebral fracture. Lighter helmets were developed and implemented in hopes of reducing injuries, but the modern trend has been to mount all the critical information and symbology on the helmet. The neck load limits under operational conditions are unknown, so the Infoscitex team is developing a methodology for establishing measurement techniques to determine the physical and cognitive effects of long duration wear of the helmets during flight missions, and how that may impact pilot performance. IST has assembled a distinguished team to address this proposal. We are proposing a novel approach to meeting the requirements called for in the solicitation. At the conclusion of Phase II, we will have demonstrated our measurement techniques in a ground-based dynamic flight simulator.

Title:Optical Heterodyne Based Hybrid Lidar-Radar Signal Receiver
Abstract:To address the U.S. Navy’s need for a hybrid lidar-radar receiver, Physical Optics Corporation (POC) proposes to develop a new Optical Heterodyne Hybrid Lidar-Radar Signal Receiver (OPHESIR) system. This proposed OPHESIR is based on a high-sensitivity optical heterodyne technology and normal-incidence, high-bandwidth and large area photodetector. It can recover 0.5–1 GHz modulated 5–30 ns laser pulses with high dynamic range over 70 dB and small loss under 10 dB. The innovative combination of intermediate frequency locking based optical local oscillator in the optical heterodyning module, and a Si-based normal-incidence detector with active area >8 mm will enable the OPHESIR to overcome the limited sensitivity, dynamic range, bandwidth, and active detection area of current lidar-radar signal receiving methods. Compact and highly efficient, the OPHESIR can be deployed on UAVs or aircrafts as a hybrid lidar-radar receiver to recover and process the radar subcarrier from a modulated pulsed optical signal. In Phase I POC will demonstrate the feasibility of OPHESIR to meet the Navy’s specifications by assembling and bench-top testing a technology readiness level (TRL) 4 OPHESIR system prototype. In Phase II, POC plans to demonstrate a fully functioning TRL 5-6 OPHESIR prototype.

Title:Lidar-radar heterodyne receiver for underwater imaging applications
Abstract:High spatial resolution, LIDAR images of underwater targets from air and submersed platforms are plagued by poor signal-to-noise ratios (SNR), arising from strong scattering in the turbid media of seawater. A hybrid system that combines the detection and coherent signal processing techniques of conventional RADAR with the optical propagation characteristics of LIDAR improves target detectability and image contrast. For this application the receiver should have a good response at the RF modulation frequency of 1 GHz and a large dynamic range to detect return signals from deep targets in highly scattering waters. Radiation Monitoring Devices, Inc. (RMD) proposes to develop an avalanche photodiode (APD) based receiver system to increase the SNR by at least ten fold and the dynamic range by more than 20 dB over existing PMT based receiver modules. The novel receiver will operate on gain modulation and heterodyne detection techniques in order to offer improved system response at the required high modulation frequency (~1 GHz). By leveraging previous experience with high performance receiver systems, RMD's highly qualified research team will design, fabricate and deliver an APD-based receiver module with ~ 1 GHz bandwidth, ~ 60dB dynamic range and a superior SNR to NAVAIR for evaluation.

The receiver, named MILOS_RX, incorporates precision time-of-flight and RF carrier phase measurement which are both critical in hybrid lidar-radar applications. The SA Photonics hybrid lidar-radar receiver leverages the coherent RF performance of the Modulated Imaging Laser Optical Source Transmitter (MILOS_TX) program (contract #: N68335-07-C- 0920 ) which demonstrated phase locking to better than 1 ps. Leveraging the MILOS_TX technology will allow precision carrier phase measurement of the receive signal. The design allows for high accuracy processing on a single pulse or multiple pulses. Autonomous self calibration ensures extremely high temperature stability. Furthermore, the MILOS_RX will be co-packaged with the MILOS_TX resulting in extremely high size efficiency.

Title:Low Profile, Very Wide Bandwidth Aircraft Communications Antenna
Abstract:With rapid advances in JTRS, the demand for broadband conformal antennas has risen dramatically. Traditionally, emphasis has been given to size and shape optimization of antenna geometry and such methodology has limitations to reach the optimum limits. The proposed research stems from Applied EM’s experience in designing spiral antennas with various loading techniques. We propose novel techniques to reach the Chu limits of miniaturization. Furthermore, recent advances in low loss magnetic materials and careful impedance matching can lead to significant frequency reduction of operation. The combination of our ultra wide band design, proper use of materials and their implementation and passive impedance matching techniques will enable us to develop configurations providing better performance than those of existing designs to meet goals of this project.

Title:Low Profile, Very Wide Bandwidth Aircraft Communications Antenna
Abstract:This proposed program will determine the feasibility of both tunable and non-tunable approaches of developing a very low profile, very wide bandwidth antenna for aircraft communications. Both approaches exploit an innovative technique to design ultra-thin antenna structures using artificial magnetic conductors (AMC), and also to minimize the surface area thus allowing antenna miniaturization using our proprietary ultra-wideband antenna technologies and patented genetic algorithms. The former approach will solve the wide bandwidth by frequency tuning, whereas the latter approach will break the bandwidth-limited, conventional, periodicity of unit cells of AMCs to achieve extremely wide bandwidth that is so important for flight platforms. The overall objective is to design and develop such an antenna to resolve also other challenging antenna issues that have been persisting for a long time, notably in the last decade with military and commercial flight platforms. These issues are for the antenna to occupy the smallest practical surface area at the lowest practical weight, without significantly impacting aircraft aerodynamics.

Concepts will be explored that can be utilized for conformal application of new antennas onto curved surfaces. As a consequence, new antenna concepts that will provide for multiple functions in a common pliable aperture will be explored and optimized.

The objective of the proposed research program is to demonstrate new computational tools and design methodologies for optimizing antenna performance while demonstrating advanced antenna constructs that may be utilized to reduce antenna profile and size, and to increase radiation efficiency in an ultra broadband, common aperture configuration.

Title:Inconel Blisk Repair Technology
Abstract:State-of-the-art military turbine engines incorporate Integral Bladed Rotors (IBR), which are one piece components consisting of blades and a disk (blisks), in the compression system. Their purpose is to reduce weight through part count reduction and improve performance and maintainability. However, to maintain affordability, the need for weld repairs of either partial or full blades is warranted to avoid expensive IBR/blisk replacements resulting from foreign object damage (FOD) to the airfoils. No adequate technology exists today to repair fielded engines. For alloys commonly used in fans and compressors, current pre- and/or post-weld heat treatment practices, as part of the repair of airfoils, result in unacceptable micro-structural degradation in the highly stressed disk portion of the IBRs/blisks. Exposing the undamaged airfoils to needless heat treatment at every repair leads to significant reduction in their structural capability. Thus a novel and enabling weld repair technology that will permit independent repair and optimization of airfoil and disk material properties is proposed to retain and restore the high cycle fatigue (HCF) characteristics of IBRs/blisks. The proposed technology has the potential to meet these requirements in addition to addressing affordability and maintainability requirements of advanced military propulsion power plants.

Title:Inconel Blisk Repair by Laser Deposition
Abstract:Blisks are important in the design of modern aircraft engines. They offer attractive performance benefits, but due to their expense they require robust repair schemes, in order to avoid costly replacement during overhaul. The Laser Engineered Net Shaping (LENS) process has demonstrated repair of blisks without compromising mechanical integrity. LENS is an additive manufacturing technique, where the original material, in this case Inconel, is deposited in the repair area to achieve a full metallurgical bond, with properties often approaching those of the original material. In this work we will develop a repair for an Inconel blisk airfoil that has suffered Foreign Object Damage. In Phase I we will investigate methods to refine the grain size of LENS-deposited Inconel, and investigate localized heat-treatment. We will also look at methods to understand and control the deposition and heat-treatment processes. In the Phase I option, we will refine the processes, model them, and test the properties of the materials. In Phase II, we will develop and demonstrate the entire repair process, and show whether proceeding to qualification would result in a return on investment for the Navy.

Title:Inconel Blisk Repair Technology
Abstract:Advanced aero engines use integrally bladed rotor (IBR)/blisks in the compressor. To maintain affordability, the need for weld repairs of either partial or full blades is warranted to avoid expensive IBR/blisk replacements resulting from foreign object damage (FOD) to the airfoils. Adequate repair technology for blisks due to FOD does not exist, and repaired blisks must meet the OEM design properties. Laser-based direct metal deposition (DMD) process has demonstrated that it can fabricate fully functional metal prototype parts, repair industrial tooling, die-casting and forging, and restore wear resistant and corrosion resistant surfaces for turbine blades. The DMD process equipped with proper sensors and numerically controlled devices can help in overcoming those hurdles to fabricate the blades. Not only thermal control to provide uniform heat flow, but spatial control of crystal texture of the blades by feedback control devices is also essential. The goals of proposal are, (1) to conceptualize, evaluate, and determine the feasibility of repair techniques that will restore the airfoils in an IBR/blisk to their original material properties after a FOD event, (2) to demonstrate cost-effectiveness of the proposed technique, (3) to identify hardware and tools needed for the procedure, and (4) evaluate improvements over current repair methodologies.

Abstract:Steady Flux, Inc proposes an innovative method for power generation for pylon mounted electronic warfare pods. The innovative design will focus on new packaging requirements by reducing packaged volume and increasing power generation efficiency by using a Francis turbine located in the aft of the pod. The approach will focus on performing detailed design and testing of the radial inlet turbine (RIT) power generation system in order to ensure all program requirements are met. Additionally, initial trade studies using state of the art engineering analysis tools will be completed in order to determine the optimum geometry and packaging. The effectiveness of the next generation of electronic warfare pods is highly dependant on sensor packaging and pod geometry. A new power generation scheme is necessary, as the current state of the art, the ram air turbine (RAT) power generation system, impedes on the next generation pod sensor packaging. By combining a Francis turbine, a proven power generation system, and a new flow geometry, the power generation requirements can be exceeded. This allows greater capability in both electronic warfare pods and other externally powered aircraft mounted devices.

Title:Pod Mechanical Power Production
Abstract:NAVAIR has developed the next generation electronic attack platform, the EA-18G Growler aircraft, as a replacement for the venerable EA-6B to effectively provide electronic attack and jammer escort for current Navy aircraft (F/A-18) and future aircraft (JSF). When the EA-18G enters service it will be equipped with ALQ-99 jammer pods that were initially designed for the EA-6 in the late 1960's. NAVAIR recognizes the limitations inherent in continuing to upgrade the ALQ-99, and, has identified a need for a Next Generation Jammer Pod with capabilities matched to the EA-18G. The NGJ Pod will be powered by an on-board turbine / generator to make the pod independent from aircraft power sources. The pod will require a minimum of 60 KVA of power generated at an airspeed of 250 knots, with the turbine/generator located within the body of the pod. The key metrics for pod power generation are weight and volume efficiency. An ideal solution for this application is a Tesla turbine, a tangential in-flow machine, that packages well, and requires only a short length of ducting to route air into the turbine. The proposed Phase 1 effort will focus in designing and testing a demonstration unit, to be followed by full-scale prototype fabrication and testing in Phase 2.

Title:A Laser-Assisted Machining Approach for the High-Performance Machining of CMCs
Abstract:Ceramic matrix composites (CMCs) are desirable for high-performance aircraft engines due to their excellent strength-to-weight ratio and their ability to withstand high temperatures. However, CMCs are expensive to machine due to their low thermal conductivity, high hardness, and abrasiveness. Creare’s innovation is a novel Laser-Assisted Machining (LAM) system for high-performance machining of CMCs. Our novel processing technique uses a laser to preheat a thin layer of the CMC material prior to its removal using conventional machine tools. By using the laser-assist, the cutting forces during machining are reduced, which enables the production of high-quality, defect-free parts at increased processing speeds. During the Phase I project, we will assemble the LAM system, complete machining tests on CMC parts, and design the system for integration on our commercialization partner’s machine tool. During Phase II, we will complete the system design, integration, and testing to be followed by technology transition and commercialization.

Title:Sequential Laser Assisted Machining of Ceramic Materials
Abstract:Physical Sciences Inc. (PSI) proposes to develop a high speed sequential laser assisted machining process for silicon carbide ceramic matrix composites. An integrated laser/high speed contact machine tool is envisioned to minimize component set-up time and abrasive silicon carbide debris. The tool achieves these goals using a laser based process for rough machining followed by high speed contact machining to finish machine through and blind features. The goal of the Phase I SBIR is to demonstrate the feasibility of a high speed, low cost laser assisted machining process for silicon carbide ceramic matrix composites that 1)Can machine features in silicon carbide CMCs with high precision. 2) Increases contact tool life by 100 times. 3) Does not degrade the mechanical strength of the machined part. 4) Can be scaled-up into a production capable machining platform. During the Phase I project we will demonstrate the feasibility of the laser assisted machining process by machining holes, slots and pockets in silicon carbide ceramic matrix composite panels. We will show that the minimal damage induced in the CMC enables the mechanical strength of the material in the machined component to be the same as that of the as fabricated composite.

Title:High Bandwidth Plasma Sensor Suite for Flow Parameter and Vibration Measurement
Abstract:We propose to develop a suite of MEMS-miniature, a.c.-driven, weakly- ionized plasma devices configured as flush-mounted sensors for direct measurement of heat flux, mass-flow, strain, and gas species for advanced engine prognostics and diagnostic monitoring. Among the advantages of plasma-based sensors are that they are mechanically robust with no moving parts, can survive high vibration and heat loading, and have a high frequency response in excess of 1 MHz. The Phase I effort will consist of designing and fabricating the suite of plasma sensors and electronics that are capable of measuring mean and fluctuating wall heat flux, flow, strain, and gas species. A MEMS approach will be used to create thin-film versions that can be vapor deposited to a surface which will have parallel applications described in the NAVY 08-004 solicitation. During the phase I, the Transonic Compressor Facility at University of Notre Dame will be used as a test bed for gas- turbine applications and during the phase II, further assessment of the sensors will be made at a test facility of choice to the Naval Research Laboratory. This work will be a natural outgrowth of our extensive experience in developing the a.c. plasma sensors for high-speed mass- flux applications which relies on the same physics as the sensors proposed here.

Abstract:Syntonics will establish the feasibility of high-temperature Surface Acoustic Wave (SAW) devices by demonstrating viable approaches to the materials science and SAW design/fabrication issues raised by extreme temperatures. SAW devices fabricated from appropriate crystal structures at certain cut angles are capable of operating at temperatures above 750 C and provide highly accurate and robust capability. Further, they are versatile and can be employed for many sensing applications including temperature, pressure, gas, strain, and heat flux and flow. Syntonics has already demonstrated the feasibility of wirelessly telemetering strain data from SAW devices capable of operating at 300 C while installed in a jet engine.

Title:Automated Knowledge Discovery and Reliability Analysis for the F414 Engine
Abstract:Impact Technologies, LLC, with support from General Electric, proposes to develop and demonstrate an automated knowledge discovery and reliability analysis tool for the F414 engine. The proposed work is fully based on the F414 maintenance data available in the Maintenance Data Warehouse (MDW) maintained by GE. Knowledge discovery techniques will be applied to unit, intermediate and depot level maintenance records obtained from the MDW. Using that knowledge, innovative reliability analysis techniques that are well suited to addressing the competing risk problem, as components are maintained before they fail, will be implemented in this effort. Once fleet-wide in-service component reliability is calculated, the reliability of each individual component will be tracked. Significant deviations in reliability will be detected early on and will be signaled to the user. An opportunistic maintenance optimization module will also use in-service reliability to provide decision support on what maintenance is warranted. Specifically the core innovations of the proposed work include: 1) a knowledge discovery module that processes maintenance records; 2) an in-service component reliability analysis module that addresses the competing risks problem; 3) development of a component reliability tracking module; and 4) an opportunistic maintenance optimization module that would maximize the expected time on wing.

Title:Wide Bandgap Amplifier Linearization
Abstract:This program addresses the challenges associated with power amplifiers used under multi-tone drive where high operating efficiency is required without adding false signals or errors (intermodulation distortion, IMD) to the output signal. The goal is to reduce all IMD levels below -30dBc without sacrificing the efficiency of the amplifier, under a signal drive condition of up to eight simultaneous tones in L-C bands with an instantaneous bandwidth of 500MHz. A broadband power amplifier technology that covers 3,4,5:1 bandwidths with an output of 25-100W will also be addressed as the basis of the project. Auriga Measurement Systems and BAE have teamed to develop a high efficiency linear amplifier. To achieve this goal, an accurate Gan HEMT device model will be created that is capable of modeling the wide bias voltage range and non-linearity of the device. Once the accuracy of the model is proven, a 50W amplifier that operates from 1-3GHz will be designed. Various techniques will be investigated for improving the amplifier efficiency, including envelope tracking, pre-distortion, and using a Doherty amplifier. Once an adequate model is developed, the foundation will be laid for developing sophisticated EW technologies, including jammers and “spoofers”, for this and other military programs.

Title:Wide Bandgap Amplifier Linearization
Abstract:Power amplifiers (PAs) providing high linearity, high efficiency and operating over a wide bandwidth are often required for tactical applications. Unfortunately, these parameters tend to work in opposition. Generally the higher the linearity of an amplifier, the poorer the efficiency. Likewise the wider the bandwidth of a PA, the lower the efficiency and the more difficult it is to achieve satisfactory linearity. Linearizer Technology, Inc. (LTI) has developed practical methods for the correction of distortion generated by PAs over multi-GHz bandwidths, and has demonstrated their effectiveness with wide bandgap devices. These techniques significantly improve PA efficiency for a given level of linearity. In some cases efficiency can be more than doubled. LTI will develop a broadband linearized amplifier module targeted for airborne phased array radar. Our goal is to provide PAs operating from 1 to 3 GHz that with 8-carriers, at a C/I ratio of 30 dB, have an efficiency of 50 percent. In Phase I system modeling and testing will be performed to identify a suitable GaN-based linearized amplifier. In Phase II a functionally equivalent module will be developed. In Phase III modules that can be flown on a test platform and used for environmental qualification will be produced

Title:Inhibitor Formulation and Automated Feed System for Catapult Water Brake
Abstract:Corrosion caused by salt accumulation in aircraft carrier catapult water brake systems reduces readiness, increase maintenance costs and lead to shorten catapult operational life. Luna proposes to develop an environmentally friendly inhibitor package for use in the water brake tank. The inhibitor will be formulated to resist foaming (antifoaming agent) and protect alloy component of the catapult and water brake system. A chemical feed system for automated control of the inhibitor addition and sensors for monitoring corrosivity of the water will be developed. Luna will optimize inhibitor system formulation for corrosion control and minimal foaming using laboratory tests that accurately replicate the water brake system conditions (flow regimes, contaminants, temperatures, pH etc). Key features of Luna’s proposed component health and usage tracking system are: 1) low cost, environmentally safe chemistry, 2) continuous monitoring of water chemistry and corrosivity, 3) automated feed system for autonomous operation, protection against general corrosion, crevice corrosion and stress corrosion cracking. Overall project goals are to develop a complete turn-key system that includes inhibitor package, corrosivity monitoring, and automated chemical feed system for use on aircraft carrier water brake tanks

Title:Robot for Re-Coating Tall Antenna Towers
Abstract:The growing maintenance burden of the Navy’s Very Low Frequency and Low Frequency (VLF/LF) towers make the development of an automated re-coating robot an appealing option for reducing support costs. Current methods of painting towers rely heavily on human agility, vision, intelligence and willingness to take risk. A key challenge for any automated system operating in this environment is to gain sufficient mobility over the tower. Boston Dynamics proposes to build a robot comprised of two major subsystems which separately address reach and dexterity. The robot will include a base platform that spans a significant portion of the tower width. A shuttle attached to this base platform will carry a small agile arm that translates along its length to reach all surfaces of the structure, much like a dot matrix printer. The base provides large reach across the span and the arm provides high dexterity to access all surfaces of the antenna. The arm will have mounted on it a vision system for surface inspection and navigation, water jetting nozzles for cleaning, and pneumatic spray equipment for painting. While many challenges remain to make this robot economically viable, we feel that this mobility solution addresses the most difficult engineering challenges.

Title:Low-Permeability Coating for Nitrile Rubber
Abstract:The TOMAHAWK Capsule Launching System (CLS) is being leveraged for integration of the littoral Warfare Weapon (LWW) on SSGN and SSN 688I/Virginia Class Vertical Launch System capable platforms. The CLS includes a nylon fabric reinforced nitrile rubber fly-through cover. During stowage of the capsule in the submarine, the fly-through cover can be exposed to seawater. The fly-through cover must seal the capsule interior, which houses a missile, from the external environment. Since the nitrile rubber is permeable, and the humidity inside the capsule must be maintained below a certain threshold, a Mylar®-tin foil-Mylar® low permeability barrier must be installed over the nitrile rubber cover. The Mylar®-tin foil-Mylar® barriers are expensive, easily damaged, and present potential debris concerns after missile launch. METSS intends to replace this barrier by adding sufficient moisture barrier protection directly to the nitrile rubber fly-through cover. This will be done through the addition of a high moisture barrier polymer composition, most likely in the form of a tightly bound coating applied directly to the nitrile rubber cover. Moreover, METSS will formulate the moisture barrier layer so that it will have acceptable life when operating in a seawater environment.

Title:Low-Permeability Coating for Nitrile Rubber
Abstract:This research will develop a coating for the nylon/NBR fly-through cover (FTC) to reduce water permeation into the missile tube. The point-to- point variability of permeation of our novel coating will be reduced compared to the MTM coating. The currently variable permeation of water compromises the mechanical integrity of the sea-wetted FTC by softening localized regions of the FTC. We will design a tape or film that will be adhered to the surface of the fly-through cover before compression molding. The tape or film will be designed to withstand at least 160 inflation/deflation cycles. We will investigate elastomeric layers and low permeability plastic films bonded inside elastomeric layers. We will investigate two commercially available elastomers as elastomeric permeation barriers. We will prepare compounds with and without platy nanofillers. We will then take the best elastomer compounds and make thermoplastic vulcanizates (TPVs) based on these elastomers in combination with low permeability plastics. Such coatings will be tested for mechanical and permeability properties. Lastly, multilayer structures comprised of the elastomeric compound or compounds, sandwiched with a highly permeation-resistant plastic film layer will be prepared and evaluated. Plastics with permeability from 20- 500 times lower than the elastomeric barrier layers will be investigated.

Title:Low-Permeability Coating for Nitrile Rubber
Abstract:Researchers have tried for years to make low water vapor transmission rate (WVTR) elastomers without success. Developing low WVTR coatings for the Tomahawk missile fly-through nitrile covers requires a breakthrough technology in barrier materials. A nanocomposite elastomer is proposed that exploits tortuous path and constrained polymer (TP/CP) effects that accrue with high aspect ratio clays such as vermiculite. A “brick wall” like structure is formed that resists water vapor permeation. Permeation improvements to factors of 100-500 compared to the pure polymer are possible with well formed nanocomposites. The result is a barrier material as impermeable as any known polymer - but still elastomeric. Candidate resin/clay combinations will form nanocomposite coatings to be tested for WVTR and elastic properties. WVTRs are projected in the range of 10e-3 gm/100 in.e- 2/day/mil, which – based on a ROM model of missile tube relative humidity – is enough for a 33 year barrier life. Physical properties will be tested for each barrier/cover combination before and after accelerated aging exposures. In Phase I Option an OEM elastomer lamination company will help develop a manufacturing strategy and produce pre-prototype fly-through cover bi-laminates for proof testing. Raw material and processing costs are low, netting at least a 40% part cost reduction.

Title:Diver Safe Grease
Abstract:The US Navy is seeking an improved grease that is safe for divers (i.e. does not off-gas toxic compounds in a pressurized air or mixed gas environment), does not wash out readily in seawater, and provides acceptable lubrication properties. METSS proposes to develop and test new, environmentally benign grease formulations that are both safe and effective, using a proven approach to cost-effective materials development. METSS will draw on existing materials, working directly with industry participants to select the best materials for product formulation. This ensures a non-biased approach to achieving the program objectives and opens up the opportunity of creating customized formulations that can be designed to directly address performance requirements. This effort will include optimizing the performance of the grease to meet and exceed the performance of the currently used greases while considering environmental impact, safety, and toxicity. To meet the Navy’s requirements, METSS will focus on combining synthetic basestocks, thickeners and additives to produce a new class of marine lubricants with superior performance properties with respect to antiwear characteristics, oxidative stability and corrosion protection. The proposed program will also address additional questions related to personnel safety and environmental impact associated with these greases.

Title:Diver Safe Grease
Abstract:Submarine hangar areas have actuated parts (doors, hatches, etc.) that must be lubricated to ensure correct operation and long service-life. The Navy currently uses Termalene�, a hydrocarbon-based grease, for this purpose. Unfortunately, NAVSEA has found that Termalene® off-gasses toxic compounds in pressurized environments, making it unsuitable for use in the enclosed and sealed areas encountered by divers during diving operations. For manned diving operations, the Navy currently uses Krytox® 240AC or Halocarbon 25-5S, which are both based on fluorinated polyethers. These greases have excellent performance and do not release toxic chemicals. However, the resistance to seawater washout is low, and these expensive materials constantly have to be reapplied to ensure adequate lubrication. This constant expense is unacceptable to the Navy. TRI/Austin is proposing to develop a new diver safe grease based on combinations of fluoropolymer and hydrocarbon greases. The new grease will, at a minimum, provide the same lubrication properties as those currently used. Additionally, the grease will offer the same resistance to washout as Termalene®, but will not off-gas any toxic chemicals, making it safe for use in sealed environments. The Navy can expect to save both time and money associated with the constant reapplication of the currently used materials.

Title:Aquatic Vessel ATR using Structural Traits (AVAST)
Abstract:To maximize situational awareness and survivability of Navy assets in littoral environments, Navy submarines must be able to quickly distinguish between hostile targets and similarly-sized non-hostile vessels. Currently, skilled personnel determine if each contact is hostile. This approach is limited by available operators, the classification speed and accuracy of each operator, the number of recognizable ship types, and operator attention spans. Automation is the key to reducing operator workload, and vision-based automatic target recognition (ATR) techniques will allow less skilled personnel to more accurately identify a wider variety of marine targets without loss of focus in a variety of challenging conditions. Model-based classification methods hold much promise for solving the ship identification problem in the varying conditions faced by Navy submarines. We propose a model-based ATR approach called Aquatic Vessel ATR using Structural Traits, or AVAST. AVAST extracts ship silhouettes from images, and derives a skeleton to model the ship’s main structures. The relative geometry and real-world measurements of these structures are computed and then used to identify matching ship types in a database of known vessels in real-time (less than 1 second per target). The matching ship types are then displayed for operator confirmation and, if necessary, refinement.

Title:An Automated Maritime Target Segmentation, Categorization and Parameter Extraction System
Abstract:Automatic Target Recognition ATR is one of the intended capabilities of Integrated Submarine Imaging Systems (ISIS) to provide a submarine with the abilities of target categorization and distinguishing between hostile and non-hostile targets. For an ISIS system, ATR performance can be adversely affected by choppy sea, low visibility, water droplets on periscope head window, the presence of recticules in the image, pitch and roll of the submarine, and blurring due to periscope motion. Recent advances in computer vision and object recognition have brought new sets of local invariant features that have the potential to effectively address the aforementioned problems. Based on these achievements, UtopiaCompression Corporation (UC) proposes a MAritime Target Segmentation, CAtegorization and Parameter Extraction (MATSCAPE) system. This innovative ATR technology offers many advantageous capabilities over existing techniques, most notably including unexcelled accuracy, multi-level hierarchical classification, ability to recognize a target that is partially visible, extremely fast classification time, robustness to illumination changes and image transformations, ability to segment target outline, ability to extract target constituent components, adpativeness and incremental learning. The proposed technology aims to reduce operator workload and operator training time as well as to enhance submarine’s capabilities in intelligence, surveillance, reconnaissance and targeting missions.

Title:Hand-Held Multi-Sensor Capture, Data Fusion and 3D Imagery System
Abstract:It has long been a maintenance and modernization problem with the time, man-power and resources required to fix and upgrade ships in the fleet. Prior to submarines entering the depot, extensive engineering and production planning is required to verify the current state of existing equipment and configurations since rarely do ships match the construction drawings. This causes a serious dilemma when ships are to be retrofitted with new equipment and maintenance teams are unable to properly install such equipment when it doesn’t “fit”. This research proposes to solve this problem by developing and demonstrating a hand-held combination laser scanning, camera and imagery system for shipboard engineering personnel to scan areas of interest and output a 3D point-cloud. These images and sensor data will be used to generate engineering drawings to identify the size and separation of equipment and structures. Using a feature recognition tool, this capability will aid future design and modeling of shipboard spaces. Engineers can render the engineering diagrams in rotational 3Dimensional views. This data can be used for engineering changes, modernization, intelligent information gathering and life-cycle support initiatives, to improve ship maintenance and decrease down time.

Title:A Low Noise Tunable Wavelength Laser for Fiber Optic Sensor Systems
Abstract:Current fiber optic towed systems under development for Naval platforms require many low noise on-board lasers built to specific frequencies ranging from approximately 1520nm to 1560nm. A low noise tunable wavelength laser, which could be tuned over the wavelength range would significantly reduce system sparing and maintainability requirements. Princeton Optronics has developed very high performance tunable lasers and is selling them for high performance applications. Princeton Optronics also has developed lowest noise fixed wavelength lasers under the DARPA Phor-Front program with unprecedented low noise of –160dB/Hz @1MHz. Current version of Princeton tunable and low noise laser has very similar external cavity hybrid design, and can easily be combined into a single design for the lowest noise tunable laser which will meet Navy’s low noise tunable laser requirement. This combination of the two designs will be achieved in the SBIR to build an ultra-low noise tunable laser meeting Navy’s needs.

Abstract:A compact stretcher/compressor for high power ultra short fiber laser system with chirped pulse amplification is proposed on the basis of longitudinally chirped volume Bragg gratings in photo-thermo-refractive (PTR) glass. Efficiency of compression will exceed 80% for average power scaling to the kilowatt level. Effects of refractive index uniformity in PTR glass and optical aberrations in a hologram recording system will be studied. High quality of stretched and compressed beams are provided by high quality of PTR glass with extreme optical homogeneity and extreme low absorption combined with an advanced technique of hologram recording.

Title:Enhanced Riverine and Coastal Sensors for Patrol Craft
Abstract:Advanced Scientific Concepts, Inc. has developed a camera that takes a 3D image of an entire scene with a single flash of laser light. This Flash LADAR is capable of acquiring 30 three-dimensional images per second at a distance of several kilometers permitting true 3D movies to be made. Our technology does not scan a scene pixel by pixel or line by line, but rather captures a whole scene with one laser flash. We propose to adapt this camera to the task of augmenting the situational awareness of the riverine battlespace by imaging through the forest lining the riverbanks. The Defense Advance Projects Research Agency (DARPA) has recently demonstrated (Jigsaw Program) a similar airborne 3D LADAR that images through the forest canopy to reveal concealed assets on the forest floor. The three-dimensional nature of this camera permits it to piece together many glimpses of the floor taken through many small holes in the canopy into a useful image of the ground. Successful field tests of this system have been recently conducted aboard a helicopter that confirm its ability to reveal hidden objects. Our 3D Flash Ladar has a similar capability and is better suited to the riverine battlespace than the DARPA camera. We propose to adapt our 3D Flash Ladar to image assets hidden near the river. Our device might also be used aboard an unmanned aircraft to reveal assets far from the river.

Abstract:The threat of attack from within obscuring foliage is a very real threat to U.S. riverine craft or other marine operations close to shore. Generally, this asymmetric situation allows opposing forces to hide undetected within or behind bushes and trees until an opportune moment for attack. On the other hand, shipboard personnel are relatively exposed and well-lit by sunlight, and have difficulty obtaining any visibility of impending attack. Technology that is able to provide visibility into the foliage at water’s edge can provide warning of suspicious activity, allowing the marine craft to assume a defensive posture or take pre- emptive action. Nanohmics proposes to build an electro-optical imaging device (called the ThruView™) capable of producing imagery within dense stands of brush, bushes, and trees. The innovative imaging system is based on hardware which records the four-dimensional light- field from objects in the field of view, providing real-time back-end processing to form images of objects that may be mostly obscured by intervening foliage. The optical system is analogous to synthetic- aperture radar or holography, and can operate in the visible, SWIR, and/or MWIR portions of the spectrum.

Title:Modeling and Simulation (M&S) of a Multiple Beam Inductive Output Tube (MB-IOT)
Abstract:The multiple beam inductive output tube (MB IOT) will play a vital role as a high-power microwave source to drive the accelerator cavities used in future free electron lasers for military systems. There is a great deal that is still unknown about the complex beam wave interaction inherent in conventional IOTs; their development has largely been a cut-and-try endeavor due to a lack of available modeling and simulation tools capable of handling the complexities of this class of vacuum electron device. Issues persist today that limit their performance and reduce manufacturing yield. We propose the development of a suite of self- consistent, physics-based finite element particle in cell codes specifically tailored to address the unique modeling and simulation needs of IOTs and ultimately MB IOTs, in an effort to shed light on the complex nature of their beam-wave interaction, which is the first step on a path to improving performance and yield.

Title:Modeling and Simulation (M&S) of a Multiple Beam Inductive Output Tube (MB-IOT)
Abstract:Electron guns from inductive output tubes are unique in that the emission is generated by RF fields between the cathode and a grid that forms a portion of the input cavity. The grid geometry incorporates small features that are difficult to simulate with current finite difference codes due to the high mesh densities required. High mesh densities for modeling the RF fields imposes very small time steps for modeling particle trajectories. Consequently, the combination of high mesh densities for the fields and small time steps for the particles results in a significant computational challenge. This program will explore techniques to achieve accuracy in both the field and particle simulations using novel approaches to reduce the computational requirements.

Title:Fiber-based, high-energy, ultra-short pulse eye-safe source
Abstract:Tactical laser sources delivering high-peak-power (from multi-MW to TW) in agile optical pulse trains at high pulse repetition frequency (PRF) in the eye-safe wavelength region are of interest for several military applications including proactive infrared countermeasures (PIRCM), non- lethal munitions, and remote sensing of battlefield threats. To meet the needs for future tactical lasers, Aculight proposes a transportable, highly flexible, fiber-based high-peak-power optical source capable of operating at eye-safe wavelengths. The proposed laser technology provides direct access to regimes of operation that are challenging or off limits for traditional pulsed solid-state sources intended for military use. The rugged, fiber-based nature of the laser enables rapid transition to battlefield deployment. The Phase I will demonstrate the feasibility of the approach through analysis culminating with a design for the Phase II laser. At the completion of Phase II, Aculight will deliver a breadboard all-fiber, eye-safe, high-energy, ultra-short pulse laser to the Navy for laboratory use.

Title:High-Energy Short-Pulse Fiber Amplifier at Eye-Safe Wavelengths
Abstract:Ultra Short Pulse (USP) laser technology offers compelling capabilities for the defense, medical and material processing industries. The development of this technology into commercial devices has been limited mostly by the size, cost and pulse energies provided by current USP laser systems. Fiber-based USP lasers have dramatically decreased the size of this technology, but the amplification of high energy pulses is still necessary to achieve the desired success for commercial USP laser devices. Power scaling of fiber lasers and amplifiers requires increasing the signal mode size to avoid nonlinear impairments and optical damage. Established approaches to scalability are inherently limited since the signal mode becomes progressively more unstable with effects such as mode competition and scrambling as the size increases. As described in this proposal, the capability to scale fiber amplifiers beyond the 100 μJ/pulse range, in a single polarization state, with high beam quality and in a compact form factor is achieved using higher order mode (HOM) propagation. Higher order modes have demonstrated scalable mode size with a high degree of stability in passive fibers. They are also fully compatible with existing or enhanced all-glass pump combiners and fiber fusion and assembly techniques.

Title:Automated Oil Reblending System
Abstract:Precise monitoring and maintenance of engine lubricating oils is essential to extend operating life and minimize engine wear. Oil analysis has long been used by the Navy for preventative maintenance of its fleet. However, the manpower requirements for these maintenance programs place a significant burden on personnel. There is demand across all the armed services for the automation of preventative maintenance operations, and a shift to more cost-effective condition-based maintenance (CBM) programs. New technologies to automate engine maintenance are also of great interested for both manned and unmanned vehicles. We propose a feedback-controlled continuous oil blending system that will eliminate the need to ever change the oil in an engine. The system employs our novel miniature electron spin resonance spectrometer, combined with a proprietary feedback system to continuously replenish additives lost during normal engine operation, without operator intervention.

Title:Reflexive Marine Systems for Autonomous Structural Repair
Abstract:CRG will develop and implement a composite structural solution with integrated structural health management capabilities enabling damage identification and mitigation through the pairing of three emerging technologies: structural health monitoring (SHM), healable polymer matrix composites, and intelligent controls. Reflexive structures, CRG's healable polymer matrix composites, have previously been developed for application into unmanned air vehicles, enabling a restoration of up to 93% of mechanical performance post-failure and subsequent healing cycle. Using the same design philosophy applied to develop reflexive structures for air vehicles, CRG will develop a composite structural solution capable autonomously monitoring the structural health of the vehicle through an integrated SHM system. The reflexive solution will have an integrated intelligent control system capable of monitoring the data output of the SHM system to determine if an anomaly is, in fact, damage, and, if so, what actions should be taken. Upon identification of damage, the control system will initiate a healing cycle consisting of heat application discretely applied to the damage through an integrated heating element resulting in restoration of up to 93% of mechanical performance. Figure 1 outlines a top-level systems graphic of information flow from damage to response in both a human and in CRG's reflexive structures.

Title:Automated Contingency Management and Self-Repair for Navy Ship Systems
Abstract:Impact Technologies proposes a Phase I program that will develop an architecture capable of extending the operational capabilities of unmanned or low-manned vehicles in the presence of functionally degraded systems. The proposed system will be capable of performing at three levels: First, the system will determine the current health state, presence of system anomalies, of mission and safety critical subsystems based on health indicators processed from raw sensor data. System anomalies can include identification of component failure mechanisms or simply scheduled maintenance requirements. Second, the system will employ model based reasoning approaches to determine the implications of any degraded elements on the overall capabilities of the vehicle to perform its mission schedule. Third, the system will be able to identify and initiate corrective self-repair actions based on the operational requirements of the mission schedule and the level of corrective technology supported by the vehicle and its subsystems. The approach will be to develop the architecture and subsystem specific diagnostic and reasoning software modules necessary for performing fault detection and self healing on critical failure modes and verify their operation, first demonstrating this approach on a representative complex system relevant to unmanned and low-manned programs, a Ship’s Supply Diesel Generator (SSDG).

Abstract:Safe insertion and extraction of riparian surface craft is an essential military requirement for the future of riverine warfare. Safe, Inc. has developed the RATV (Riparian All-Terrain Vehicle) – a comprehensive transport, launch, and retrieval system that will reduce Time-On-Site by a factor of four and will greatly expand the operational footprint via enhanced terrain navigation capabilities inherent within the proposed technological architecture. The system is also fully compatible with legacy trailers and tow vehicles to support a gradual cross-over transition. Additionally, initial engineering estimates have verified that the proposed concept will meet military transport requirements for lift capacity and space claim for the MH-47, MH-53, C-130, C-17, and C-5 aircraft as well as roll-on/roll-off for amphibious vehicles (LCAC, LCU). In Phase I, Safe will develop a draft capabilities document (ICD), mature the design concept, verify transportability, and provide a Risk Assessment for the proposed technologies. In Phase I, Safe will also develop the Phase II team framework to fully commercialize this novel system. The RATV’s agility, maneuverability, range, flexible transport options, support for legacy systems, and robust launch and recovery device represents the future for Naval riverine combat.

Title:Advanced Sabot System Design
Abstract:Simulations, LLC, a privately held small-business engineering company, and team members DR-Technology, the U.S. Army Research Laboratory (ARL) and Douglas Elder, proposes to develop the material and fabrication methodologies to produce a lightweight, high-strength, low- cost composite sabot based on innovative configurations. Simulations will springboard from: (1) the current ONR Projectile IPT sabot subsystem concept; (2) two proven ARDEC SLEKE, Area I, four-petal, ribbed, aluminum sabots; (3) the Army D2 six-petal, uniaxial graphite- epoxy composite sabot development efforts, and; (4) the ILP design experience of the Simulations team. Simulations will innovate geometries, perform structural analyses and optimize configurations, materials and fabrication methodologies. The approach will use lessons learned from a collage of conventional and electromagnetically launched sabots, while utilizing Simulations parametric finite-element- analysis code FATE. FATE is a proprietary customized code, developed by Simulations for the ARL. FATE is used for analytically designing integrated launch packages, thus making it immediately idyllic for the Navy’s Advanced Sabot System Design. FATE is the core structural analytical tool supporting ARL’s F5 double-tapered sabot-armature designs. Based on F5 and FATE successes, Boeing contracted Simulations to size, design and analyze the Navy’s Phase I base-push and mid-ride topologies in 2006. Consequently, Simulations showed parasitic ILP masses approaching 30%.

Title:Geometry- and Performance-Tailored Composites for Advanced Sabots (1001-192)
Abstract:Triton Systems Inc., in collaboration with BAE Systems and Specialty Materials Inc. of Lowell MA, proposes to develop an extremely lightweight Boron composite sabot for hypervelocity Navy fire support projectiles, in order to substantially reduce parasitic mass and improve projectile accuracy, thus improving overall projectile effectiveness. The proposed sabot consists of three major elements: • An inner, segmented conical frustum, conformal with the sharp cone projectile, and fabricated from Boron/Epoxy composite. • Forward and aft bore riders, fabricated of a Boron/Epoxy composite or a hybrid Boron- Graphite/Epoxy composite. While tradeoffs are planned during the Phase I to optimize the selection of materials, the Boron/Epoxy composites from Specialty Materials Inc. show weight specific compression strengths nearly 10 times those of high strength Aluminum and Titanium alloys and 70% higher than corresponding graphite/epoxy composites. During the Phase I, Triton will identify and trade-off promising sabot construction materials and architectures, selecting both an optimum configuration and manufacturing method. Trial components will be fabricated of simplified geometry and subjected to both static compression tests and gun launch environments. During the Option Phase the sabot system configuration will be updated based upon Phase I testing results, and more representative pre-prototype models fabricated for delivery to NSWCD-D.

Title:Marine Assessment, Decision, and Planning Tool for Protected Species (MADPT PS)
Abstract:The overall objective of this SBIR proposal is the development of a software-based tool or database known as the Marine Assessment, Decision, and Planning Tool (MADPT) for Protected Species. Knowledge about federally protected species such as fishes, marine mammals, sea turtles, and invertebrates such as corals or abalone is vital for scheduling at-sea activities so that potential impacts to these species can be avoided or minimized. Ready access to pertinent information about a marine species, including its distribution, density, behavior, life history and bioacoustic parameters, environmental stressors, and key habitats is critical for environmental planners, environmental compliance specialists, scientific researchers, and others to make informed, science-based decisions about locating at-sea or marine activities and the potential impacts of those activities on protected species and habitats. This database tool will be designed to provide ready access to the needed scientific information and data on marine species, especially those protected by United States federal regulatory mandates. The first step, or Phase I, of this effort will entail demonstrating the feasibility of developing and generating such a comprehensive database by selecting one taxon of protected species, fishes, upon which to focus the development and later data-population efforts.

Title:Datagram Segregation Open Systems Service Approach
Abstract:3 Sigma Research proposes an innovative approach to develop a open architecture based data model and process for adding self-identifying information to a datagram. The power of our potential solution is in applying results from our research of Packaged Ontology Certificates to the unique performance issues with real-time processing of datagrams. Combining this with a revolutionary way of viewing how application development environments can enhance and facilitate the open services model of enterprise servers can potentially remove many of the obstacles that hinder migration to Service Oriented Architectures in a Global Information Grid (GIG) framework. Our Packaged ONtology Certificate Real Time Model (PONC-RTM) Investigation explores the concept for an enterprise information architecture that makes use of a PONC integrated into the datagram to extend automated, appropriate, delivery controls for information. Our innovative approach combines the power of ontology-based reasoning components in scalable open architecture to address the process of making intelligent decisions with regard to restrictions, purpose, and context of the data content.

Title:An Environment Agnostic Architecture for the Identification and Modification of Network Datagrams
Abstract:As the Navy moves towards a Service Oriented Architecture (SOA) through initiatives such as Consolidated Afloat Networks and Enterprise Services (CANES), the high-level control of network information will become ever more important. This need is especially pronounced when dealing with complex and interrelated data flows. With such highly distributed yet interconnected network nodes, the ability to identify and act upon messages or portions of messages that should be restricted, redirected, reformatted, or otherwise modified is extremely valuable. This document addresses these concerns by proposing a flexible and modular architecture to identify those datagrams which need some form of modification and to perform such modification in a generic user- specified way. The solution relies heavily on accepted web services standards and makes abundant use of Extensible Markup Language (XML) and related technologies and standards. In addition, the components of the architecture are able to integrate with a wide variety of hardware and software systems on multiple platforms as well as operate at the network level. Support for multiple network protocols with the ability to expand those supported will also be provided. The proposed solution is highly commercializable due to its adaptable design and multi-use capability.

Title:High Fidelity Clutter Model for Active Sonar
Abstract:Active sonar clutter usually appears on a display as an amalgamation of point scatterers that exhibit both object and individual reflective and kinematic behavior. We propose to demonstrate the feasibility of constructing a realistic active sonar clutter model based on a few generalized concepts to synthesize most clutter types observed on Mid- Frequency active sonars. Realism is achieved by using the statistics of known clutter object attributes obtained from existing databases. The clutter model uses superellipsoids to define basic building blocks. Each type of clutter block is populated with discrete point scatters. The population, density, scattering coefficient, velocity, and fading characteristics of the scatterers are described using the appropriate statistics. The acoustic propagation response function for each scatterer is obtained using a high fidelity acoustic model. A realistic time series of a clutter object echo is obtained by convolving the transmit waveform with the system, propagation and clutter object response functions. Because all the functions, save one, are represented as delta functions, this is not computationally intensive. The model includes the effects of own ship motion, the specific sonar design, waveforms, and acoustic propagation including attenuation and multipath arrivals. The clutter exhibits deterministic and stochastically dependent, spatial, temporal, and intensity characteristics.

Title:Active Sonar Automated Clutter Management MP 03-08
Abstract:The goal is to develop an inexpensive and ubiquitous synthetic sonar operator training environment for Mid-Frequency Active Sonar (MFAS) systems which can be realized on inexpensive hardware. "Display ready data” will be generated as realizations of random fields that are based on statistical characterizations derived from real and modeled data. An effective and inexpensive supplement to full-physics approaches such as that used in SMMTT methods is envisioned. This random field approach is likely to come quite close to the fidelity of the full-physics approach. The ubiquitous nature of the targeted training hardware will allow operators to practice recognition skills much more frequently by making quality training available outside underway and team trainer access time. This is critical to the preservation and continued development of operator proficiency. It will also allow the operator to experience many more environments and scenarios than can be packed in the few days of training currently embedded in ship’s crew curricula.

Abstract:New types of surface combat vessels are being developed for use in littoral warfare. These ships are designed to meet the evolving mission of the Navy which includes providing forward presence and dominance and support of expeditionary forces. The new mission requirements motivate the use of new hull-forms such as the tumblehome hull used in the DDG 1000. Improved heave sensors are needed to help ensure that vessel operation remains within the design envelope and to provide detailed measurements of vertical motions for use in weapons guidance. This project involves development and demonstration of a novel heave measurement system that eliminates the low-frequency drift problems plaguing current approaches. During Phase I, we will develop a prototype system and measurement of prototypical vertical motion profiles.

Title:Gyroscopic Null-Offset Accelerometer
Abstract:To address the Navy’s need for a heave measurement system with low drift, Physical Optics Corporation (POC) proposes to develop a new Gyroscopic Null-Offset Accelerometer (GYNOA). This proposed device is based on a novel Gyroscopic Accelerometer Mount (GAM). The GAM overcomes present accelerometer limitations of heave measurement by a parallel vector transformation that reduces heave accuracy error to <1 mm over 7 days of operation. GYNOA is 50 times more accurate than presently used systems, which offer an accuracy of only 5 cm. GYNOA will feature a system size of 8.0 cm diameter and 10 cm tall, power usage of <1 W, weigh <1.5 kg, and be able to operate either wired or wireless. Initial cost estimates indicate that the system could be sold for as little as $200. In Phase I, POC will demonstrate the feasibility of GYNOA by creating a proof-of-concept device and measuring the displacement of a vehicle in motion and validate the solution when compared to a series of performance metrics. In Phase II POC plans to develop a full prototype capable of measuring heave onboard a ship to show its high accuracy and provide a cost/benefit analysis of GYNOA for transition to Phase III.

Abstract:The proposed project will create an innovative sensor system to augment an outer ring of defense used for queuing, classifying, and tracking go-fast boats, small and commercial craft, swimmers and divers that are a threat to harbors, anchorages, and other high value assets. The Modular, Deployable Sensor System (MDSS) will be part of the Navy’s deployable capability in locations where US or host nation security infrastructure is either inadequate or nonexistent. It utilizes a combination of proven sonobuoy sensors and adaptations of current technologies to meet the mission needs. SkySight Technologies’ experience and expertise, combined with this unique approach, creates a low cost, lightweight, modular, and reusable system to be easily deployed and recovered by a single person in a small surface craft. The MDSS system more than doubles the targeted time between servicing and is capable of being moored in littoral waters for extended periods because of an innovative, multi component, mooring system. In addition to a baseline of proven passive acoustic sensors, this Phase I study utilizes external funding to investigate the feasibility of including innovative alternative sensors and processing techniques for the Phase II and beyond. The MDSS system fills a critical gap in Navy sensors.

Title:Improved Magnetic Shielding for Superconductor Electronics
Abstract:HYPRES has developed and demonstrated a family of wideband digital- RF receiver systems for applications in satellite and RF communications, signal intelligence and electronic warfare. In the heart of these systems are ultrahigh speed circuits of superconductor digital electronics. For a high fidelity operation, superconductor electronics needs magnetic environment that attenuates magnetic fields associated with Earth, system platform, and low frequency magnetic interference. This proposal focuses on the development of the novel approach to magnetic shielding of electronics – active magnetic cancellation. It is proposed to develop a hybrid magnetic shielding system comprised of a conventional mu-metal shield and a system of active canceling of the residual fields inside the shield. The system will include high-sensitivity magnetic sensors based on superconducting quantum interference filters – devices which can sense the absolute zero of magnetic field – and a feed back system with thin wire coils for active canceling. It is expected to achieve a factor of 100 improvement in the performance of such a magnetic environment in comparison with the existing passive magnetic shielding. When developed the active magnetic shielding system will become an integral part of the cryogenic package of all HYPRES digital–RF systems for DoD and commercial applications.

Title:Low-Profile Magnetic Shielding for Circuit Board Electronics
Abstract:Electronic components sensitive to magnetic fields, such as superconducting digital electonics, require magnetic shielding from ambient fields and magnetic pulses. While enclosures of high permeability magnetic materials are commonly used to achieve passive flux shunting, the structures are substantially larger than the circuitry being protected. For military and commercial satellites, this adds undesired volume and weight. A substantially lower-profile solution is proposed here in which stray magnetic fields are both passively shunted and actively nulled. The shielding assemblies are small and can be used alone or in arrays to cover desired areas of electronic components on printed circuit boards. The assemblies are expected to produce substantial magnetic-field reductions and yet have at least three times less the volume and weight of a purely passive shield.

Title:Materials and Device Modeling to Reduce Cost and Time to Exploit Relaxor Piezoelectric Single Crystals in Navy SONAR Transducers
Abstract:This SBIR proposal addresses the need for a transducer design methodology to reduce the cost and time for inserting into Navy systems innovative transducers based on relaxor piezoelectric single crystals. Together with the proposal submitted in response to NAVY 08-063, it forms a coordinated program that integrates the efforts, interests and areas of expertise of sonar system designers, transducer designers and materials developers. While the NAVY 08-063 proposal offers a moderate fidelity toolkit that enables the system designer to explore the transducer design space, the NAVY 08-061 proposal described herein provides the infrastructure for high fidelity materials and device modeling designed to reduce or eliminate the costly design/build/test cycles. The Phase I effort will focus on the Tonpilz transducer, commonly used in sonar array designs. We will develop a user friendly high fidelity Tonpilz model and validate the model by building and testing an exemplar device composed of single crystal. To represent a real Navy sonar problem, the exemplar device will be based on the PZT design currently used submarines. A comparison between the legacy and the new single crystal design will be made.

Title:Materials and Device Modeling to Reduce Cost and Time to Exploit Relaxor Piezoelectric Single Crystals in Navy SONAR Transducers
Abstract:The discovery in 1996 of a group of relaxor-based ferroelectric single crystals with electromechanical properties superior to those of traditional PZT has generated considerable interest in for defense sonar. Recently, it has become evident that greater experience and improvements in materials processing has begun to yield a greater supply of reliable and consistent materials appropriate for designing and building practical devices. However, there still remains a significant gap in experience applying these materials to practical devices. Closing this gap requires significant expansion of the knowledgebase of available properties including the reliability, behavior over time and range of operating conditions. Materials Systems Inc. has excellent capabilities and more experience in the application of novel transducer materials to Navy sonar systems than any other small company. In the proposed program, MSI will work closely with Weidlinger Associates, Inc. and material vendors to begin addressing piezoelectric single crystal application issues through a series of characterization, design and validation studies. This will include detailed characterization of selected materials for input into Finite Element Analysis models, validation of these properties with measurements of material samples and design- build-test of a practical Navy device.

Title:Crystal Tensile Properties for High Power, 1-3 Composite Projector Design
Abstract:In this Phase I SBIR program TRS Technologies will develop high power, high frequency 1-3 composite transducers for high resolution imaging at ranges sufficient for naval applications such as mine classification. In order to understand and model the performance of 1-3 composite projectors, we will measure the electromechanical properties of crystals subjected to tensile stress. We will also initiate characterization of the full dielectric, piezoelectric, and elastic property matrices of thermally stable ternary crystals. In Phase II this effort will be extended to high field, high stress electromechanical properties and thermal properties. In collaboration with Penn State Applied Research Laboratory, we will also begin development of new modeling techniques that will incorporate nonlinear effects with field, stress, and temperature. At the conclusion of the Phase I program, TRS and our team will have demonstrated the feasibility of using crystal 1-3 composites for high power, high frequency projector applications. This will serve as the basis for developing full scale transmit/receive arrays for side scan imaging systems in Phase II.

Title:IMPACTS – A tool for the Improvement And Measurement of Perceptual, Attentional, and Critical Thinking Skills
Abstract:Attacks against patrols and convoys have become one of the defining characteristics of Operation Iraqi Freedom, with ambushes by snipers and improvised explosive devices (IEDs) accounting for a large proportion of US casualties due to the difficulty of detecting these threats in a complex and foreign environment. This proposal respond to the problem by presenting a plan to develop IMPACTS, a comprehensive system for the Improvement And Measurement of Perceptual, Attentional, and Critical Thinking Skills. IMPACTS consists of several components, which provide capabilities such as anomaly detection training, decision support, team collaboration, and training content development. IMPACTS features several innovations in instructional technology to ensure efficient, accelerated learning. In Phase I, we focus on addressing several key enablers needed for system development, including acquisition of domain knowledge, development of methods and technologies for optimizing training in that domain, and identification of a suitable testbed for developing training materials and approaches.

Title:Simulation and Visualization for Perceptual Skills Screening, Training and Operations
Abstract:In Iraq and Afghanistan, the U. S. military faces an opponent that attacks by unconventional means such as improvised explosive devices and snipers. A key to insurgent success is to blend into the environment. Advanced observational skills can mitigate these insurgent tactics by detecting visual anomalies. The U. S. military trains warfighters in observational skills to detect visual anomalies associated with unconventional devices and tactics. We propose to update and extend this training as informed by current scientific research in visual anomaly detection. We will analyze and characterize typical visual anomalies, analyze current training techniques, develop metrics, and conduct an experiment to determine whether neurophysiological correlates of visual anomaly detection exist and may be used to enhance training or augment performance. We will document a framework for a simulation- based training tool to improve observational skills for visual anomaly detection, and produce a roadmap for development and transition of a simulation-based training tool.

Title:User Toolkit for Reducing Cost and Time in the Design of SONAR Systems Using Relaxor Piezoelectric Single Crystals
Abstract:This SBIR Proposal addresses the need for a transducer design methodology to reduce the cost and time for inserting into Navy systems transducers based on relaxor piezoelectric single crystals. This goal will be achieved by devising user friendly transducer toolkits to allow sonar systems engineers to readily evaluate transducer types and configurations to meet given system requirements. These toolkits will be of moderate fidelity, yielding preliminary transducer design information forming the basis of more accurate high fidelity models implemented by transducer designers (covered separately under NAVY 08-061). Transducers such as Tonpilz, rings, flextensionals, slotted cylinders and benders are used in sonar systems, with Tonpilz the most common because of its use in large arrays. We plan to focus on the Tonpilz transducer during this Phase I program and develop a user toolkit as an example of the many types that will be developed under a Phase II program. This single crystal Tonpilz transducer toolkit will be evaluated through comparison with measured data as well as FEA and high fidelity models. The specific single crystal design will be based on a PZT design currently used in a sonar system. A comparison between the legacy and new single crystal design will be made.

Title:A Graphical Database for Streamlined Single Crystal Transducer Design
Abstract:Single crystal piezoelectrics promise to revolutionize underwater acoustic and ultrasonic transducers with broader bandwidths, greater resolution, greater range, reduced transducer size and weight, and reduced power requirements. However, there are many differences between the properties of single crystal and ceramic piezoelectrics which make it difficult to simply replace ceramic with crystal in existing transducer designs. For this SBIR program TRS propose to develop a user friendly, graphical program that will serve as a toolkit for transducer designers, allowing them to quickly evaluate a range of design parameters that have already been verified by established transducer models using a consistent data set. By implementing a database and simple model approach based on empirical data, various transducer types and parameters can be tested with limited prior knowledge of single crystal properties. Through the graphical interface, the user will be able to choose performance characteristics and observe output data and drawings of calculated transducer components. The Phase I program will focus on tonpilz transducers for sonar.

Title:User Toolkit for Reducing Cost and Time in the Design of SONAR Systems Using Relaxor Piezoelectric Single Crystals
Abstract:WAI will develop a suite of User Toolkits for SONAR Transducer Design, to enable rapid and accurate evaluation of new design concepts, allowing quick selection of appropriate candidate designs for further evaluation. This will reduce overall design costs and time from concept to market. The Toolkits will be heavily influenced by devices incorporating single crystal piezoelectric materials. The technology for the simulation used in the Toolkits will be based on PZFlex, a finite element simulation package heavily used in the ultrasound and SONAR communities, leveraging decades of development effort in that field. The Toolkits will allow for all relevant input parameters (materials, dimensions etc) to be varied, while calculating and displaying all key output metrics such as electrical impedance profile, TVR, and directivity. WAI, in partnership with Materils systems Inc, will initially develop a Toolkit focused on the Langevin (sandwich) class of transducer, for consideration for use in the AN/AQS-20 Minehunter. Following development and validation of the Toolkit, MSI will design a candidate Forward Looking SONAR with the Toolkit, incorporating single crystal piezoelectric material, to replace the existing Tonpilz design. Key performance metrics will be compared with existing data to highlight improvements available from use of new design and materials.

Title:Hyperspectral Capability for Foveated Zoom Imaging System
Abstract:Boulder Nonlinear Systems proposes to investigate the feasibility of adding a hyperspectral imaging capability to a foveated zoom system currently under development for use on unmanned air vehicles. The hyperspectral information along with the selective enhancement of a region of interest within a field of view in a foveated imaging system reduces the bulk and complexity of the imaging optics and reduces data transmission and processing requirements on the sensor system. In Phase I, Boulder Nonlinear Systems will integrate hyperspectral imaging and foveated zoom capabilities using the reflective liquid crystal on silicon spatial light modulator common to implementations of both. Compared to other approaches, the likelihood of success for the proposed effort is improved by leveraging the component maturity of the spatial light modulator technology, along with our recent extensive experience in adaptive and spectral imaging.

Title:Advanced Optics Zoom Hyperspectral Sensor
Abstract:To address the U.S. Navy’s need for an Advanced Optics Zoom Hyperspectral Sensor, Physical Optics Corporation (POC) proposes to develop a new Advanced Hyperspectral Zoom Optics System (AHZOS) System based on POC’s mature 360 omnidirectional optics and high- refractive index optical materials in a compound zoom configuration. Innovations in the optical design of this system enables it to achieve a wide-angle field of view (>60) for a hyperspectral sensor in a compact form factor (<150 mm, <1.5 lbs) package suitable for use on the handheld class of Navy unmanned aerial vehicles. Innovative folded optics combined with high-refractive index (n>2) materials offers a continuously variable zoom telescope with close-up imagery capability (up to 20x) and offers broadband wavelength operation from 0.4 microns in the visible to 6 microns in the infrared. In Phase I POC will demonstrate the feasibility of AHZOS to Navy personnel by assembling and testing a Technology Readiness Level (TRL) 4 prototype. In Phase II POC plans to develop a TRL 5-6 prototype to show how the approach will provide a wide field of view while searching for targets of interest and a narrow field of view for homing in once a target is identified.

Title:Advanced Optics Zoom Hyperspectral Sensor
Abstract:UltraSpectral Inc. is leading a team consisting of Panavision Federal Systems, LLC and Opto-Knowledge Systems Inc. in proposing development of an innovative airborne visible through shortwave infrared (SWIR) hyperspectral imaging system which incorporates novel compound zoom (CZ) lens technology. Our system will be compact, lightweight and capable of day hyperspectral imaging and multispectral to broadband SWIR imaging during low light level and night conditions. The system will include hyperspectral analysis, camera control and visualization software to reduce operator workload and enhance situational awareness. In Phase I we will interface a commercial 300X magnification CZ lens with a scanning mirror-equipped hyperspectral camera and a pan/tilt mount, and will perform roof top target acquisition and tracking investigations. In Phase 2 the system will be optimized for airborne visible-SWIR imaging and a flight demonstration will be conducted. The system will provide significant advances in airborne hyperspectral surveillance and tracking, allowing hyperspectral sensors to be used in a continuous surveillance mode. The CZ will allow dynamic tradeoffs between field of view and spatial resolution to achieve both wide area scene monitoring and accurate target characterization. We anticipate strong interest in the system throughout DoD, other government agencies and commercial airborne remote sensing companies.

Title:Advanced Characterization Techniques that Improve Durability of Fracture Critical DoD Components
Abstract:Many DoD systems employ fracture critical and/or retirement for cause methodologies for asset deployment, operation and management. They are a key element in the design and certification of turbine engines including the F100, F119, and F135. Critical to this approach is the characterization of structural materials and development of life prediction methodologies and application of these to component design, validation and assessment. In structural metallic systems fracture mechanics approaches provide the foundation, however variability and uncertainty are introduced due to the presence of many factors including residual stresses, material variability, complex damage environments, etc. These factors can influence life assessments by factors of four or more. Mission cycles for hot section components such as turbine airfoils are complex and test methodologies such as strain- controlled TMF have not been sufficiently standardized and matured to provide repeatable results across a broad range of facilities and environments. The complex loading profiles these components experience are a further complication. This can lead to reduced durability in key hot section components. The goal of this proposal is to demonstrate the feasibility of newly defined approaches to test specimen thermal gradient management, and thermomechanical cycle time reduction as pertains to strain controlled thermomechanical fatigue testing.

Abstract:The objective of this proposed effort is to develop and demonstrate tools and techniques for detecting fatigue and fractures in critical DoD components. Under the proposed effort, Vibrant will attempt to adapt Process Compensated Resonance Testing (PCRT) technology, to detect fatigue and fractures in DoD components. PCRT uses Resonant Ultrasound Spectroscopy (RUS) coupled with genetic sorting algorithms to determine the unique resonance patterns of components. Vibrant’s efforts will focus on developing advanced fatigue and fracture characterization techniques to assess turbine component durability. Vibrant’s technology will be used to provide a non-destructive evaluation (NDE) technique to assess whether fractures or thermal- mechanical fatigue (TMF) is present in components. This new capability will provide higher confidence assessments and improved durability management of fracture critical DoD components that is not available currently.

Title:Magnetometer Arrays for Diagnostics, Control, and Life Management of Electromagnetic Launchers
Abstract:Railguns offer unique value compared to alternatives, primarily due to cost and logistics advantages, assuming that the sustainment costs are comparable to or lower than alternatives and life management can be integrated into Navy standard practice. JENTEK can help realize the potential offered by railguns by introducing reliable nondestructive testing solutions, practical embedded sensing for diagnostics, and teaming with OEMs to deliver comprehensive life management solutions. In this program, JENTEK will develop tools and methodologies to address life-limiting processes associated with railgun bore changes, such as erosion and material deposition. This will be accomplished not only via in-situ MWM-Array scanning characterization of rail surfaces (feasibility already demonstrated), but also with arrays of embedded magnetometers. During the launch these arrays will provide real-time information on magnetic fields, temperature, current density, and possibly stress, with high spatial and temporal density. Such data would be extremely valuable not only for improved modeling of the launch process and enhancement of future railgun designs, but also for active launch process control, maximizing efficiency and minimizing rail damage. We will also develop hardware and software tools for adaptive life management of electromagnetic launch systems.

Title:Advanced Diagnostic Techniques for a Naval Electromagnetic Launcher
Abstract:The nature of electromagnetic launchers requires operation in a harsh environment due to the large electromagnetic field, electrical current, temperature, and mechanical stresses present during a shot. This environment can significantly reduce the lifetime of the rails and therefore limits the military utility of the device. Increasing the lifetime of the rails while maintaining high launch velocities is a critical requirement for electromagnetic launcher development and is the focus of a number of ongoing research efforts. These efforts, however, are hindered by a lack of diagnostic capabilities to support the modeling and simulation needed to design better launchers. Diagnostics are a particular challenge for electromagnetic launchers for a number of reasons, including a lack of access to the interior of the launcher, electromagnetic interference with sensors that use electrical signals, and high temperature and mechanical stress conditions that make survivability of sensors an issue. The electromagnetic launcher modeling and simulation (M&S) community has identified a number of parameters that represent critical diagnostic capability shortfalls for electromagnetic launchers. The highest priority items on that list are temperature, magnetic fields, and stress measured with sufficient spatial and temporal resolution. This proposal describes a novel phosphor-based approach to measuring temperature at the rail-armature interface with a very high frequency response sensor in order to address this critical diagnostic shortfall.

Title:Fused Optical Railgun Diagnostic Sensor
Abstract:To address the Navy need for wide-bandwidth sensors capable of measuring magnetic/electric/temperature fields and assess the equipment health of an electromagnetic launcher, Physical Optics Corporation (POC) proposes to develop a new Fused Optical Railgun Diagnostic (FORD) Sensor based on the novel sensor fusion technique using three fiber optic sensors. The proposed technique uniquely integrates electro-optic sensing elements with polarization-maintaining optical fibers, which will enable the FORD sensor system to simultaneously measure magnetic fields (as high as 30 Tesla), electric fields, and temperature with the bandwidth of at least 1 MHz. The sensoring heads are based on optical transducer design using rugged materials, which allows operation at high temperatures of up to 300 degrees celsius, and will allow fabrication of an all-optical magnetic sensor immune to the electromagnetic interference. In Phase I, POC will demonstrate the feasibility of the FORD sensor technology by designing, analyzing performance, and building a breadboard prototype which will survive static magnetic fields of 30 Tesla and temperature of 300 degrees celsius. In Phase II, POC plans to fabricate a rugged, stand- alone, FORD sensor prototype system with electronics and data acquisition to be tested in transient environment similar to the railgun.

Abstract:Prime Research, LC (PRLC) with the expert assistance of Lawrence Livermore Nation Labs (LLNL) proposes to develop a suite of diagnostic sensors for electromagnetic launchers (railguns). Measurement capabilities to be provided include strain, pressure, electric field, and magnetic field. This suite of photonic sensors is based on an entirely dielectric fiber optic platform which renders it immune to any issues with the harsh electromagnetic environment. Each sensor is capable of withstanding temperature in excess of 300°C, and all have frequency response characteristics in excess of 10 MHz. In addition to the transducers, the proposed effort includes modification of the PRLC sensor interrogation technology to allow for modular selection of transducers. Upon fabrication of the sensors, they will undergo laboratory testing. In the Phase I option, the effort will be expanded to include testing in a representative railgun environment, as well as investigation of instrumenting the armature.

Title:Live Fire Virtual Sniper/Counter Sniper Training System
Abstract:The U.S. Navy provides training to troops, mainly Marines and Seals, to prepare them for urban combat. This training consists primarily of marksmanship and shoot/don’t shoot skills in virtual environments and live fire training exercises in “shoot houses.” Although it is very effective in instilling these types of skills, the aspect of realistic training in real world, dynamic situations is missing. In addition, the current systems are not portable nor do they integrate classroom and live fire exercises. Laser Shot will conduct research into providing a movable, realistic virtual training system that promotes a “train as you fight” environment. This will lead to improved training effectiveness by increasing the ability of the trainees to achieve a true “suspension of disbelief” and feel realistically immersed in their training environment. Work to be performed during Phase 1 includes research and assessment of the technology necessary to produce such an environment and the integration of this technology into the design of a portable, modular, containerized, counter-sniper virtual environment that enables and enhances the realism of both live and simulated infantry training. Government Off-The Shelf protocols and Commercial Off-The Shelf products will be utilized to the maximum extent possible.

Abstract:The Deployable Interactive Virtual Environment Sniper Trainer (DIVEST) is a innovative use of existing technologies in a novel application. Sniper training requires the ability of the trainee to exercise observations skills (reconnaissance), marksmanship skills, and as a fighting team – sniper and spotter – decision making skills. Using gaming technology, open source systems, instrumentation, and a scalable full movement “Play Box,” DIVEST will bring state-of-the-art Virtual Environments (VE) to the high fidelity reconnaissance and marksmanship training requirements needed by the military’s elite Snipers. Phase 1 of this effort will develop a prototype training system design using open source Commercial Off -The-Shelf (COTS)/Government Off-The- Shelf (GOTS) technologies that will allow the trainee freedom of movement, in a necessarily limited “play box”, realistic viewing of “targets”, real weapons and sites, and a high level of realism in interacting with the synthetic (or gaming) environment. The Phase 1 (Option) will iterate the design determined in Phase 1 and begin the technical determination of the interfaces and development necessary to build the prototype training system in Phase 2.

Abstract:Cross-correlation technology investigated in this effort improve electronic warfare and signals intelligence capability relative to that which is known to be deployed. Agility enables detection of new threats followed by rapid, in-theater generation of robust detection templates. Robust templates and detection systems identify and track threats across many changes in relative locations, velocity, acceleration, propagation medium, encodings and number of concurrent emitters. Use of low-temperature receiver and correlation technology increases both the concurrent search bandwidth (HF to 40GHz) and sensitivity beyond alternative room temperature approaches. The algorithmic techniques could be implemented at room temperature with reduced capability.

Title:Reference Template Generation for Cross-Correlation Based Receivers
Abstract:Welkin Sciences proposes to develop the Template Identification Processing System (TIPS), a very-high-speed digital signal processor implemented on the company's DataFlowDSP(TM) hardware platform, an interconnected network of FPGAs and embedded general-purpose CPU blades. The TIPS works in tandem with a cryogenic RSFQ-based sub- system to form a complete signal identification and discovery capability. The RSFQ components digitize a wideband RF input signal and the room-temperature TIPS analyzes the digitized signal stream to generate signal signature templates for previously unknown signals. The proposed TIPS design is intended to serve three purposes: 1) a development platform for real-time template generation algorithms; 2) a fielded first-article template generating processing unit that can be built and delivered within the budget and schedule limitations of an SBIR Phase II program; and 3) a development platform for the algorithms that match (or correlate) the received signal with the list of signal signature templates (ideally such algorithms would migrate to the RFSQ sub- system). The proposed TIPS design employs a truly open architecture philosophy based on COTS hardware components in the industry standard ATCA form factor. Software development tools used for this project are entirely open source (Linux/GNU), and the firmware is developed using the familiar MATLAB platform, the same toolset used to develop and refine the DSP algorithms in the conceptual design phase prior to implementation.

To minimize discharging harmful waste into the environment, all marine vessels with toilets must have a marine sanitation device (MSD) to process wastewater, rendering it harmless. The two key indicators of the quality of treated wastewater are fecal bacteria (measured as fecal coliform content, or FCC) and organic material (measured as biological oxygen demand, BOD). However, the standard methods for measuring these are laborious and require one and five days, respectively. In order to monitor the performance of MSDs and minimize storage of treated waste, more expeditious FCC and BOD assays are needed. During the proposed Phase I, Luna will identify and develop rapid fluorescent bioassays for accurately predicting and measuring these key indicators in MSD effluent. The assays will be based on the use of fluorescent markers for measuring bacterial metabolism of, i) fecal bacteria for determination of FCC and ii) bacterial seed consortia for determination of BOD. In preparation for Phase II, during the Phase I Option Luna will begin formatting select assays into kits for simple use with a hand held fluorometer onboard marine vessels.

Title:Rapid and Label-Free Fecal Coliform Enumeration
Abstract:US Navy ships generate substantial quantities of wastewater from toilet, laundry, shower, galley and other sources. An aircraft carrier alone can generate nearly half a million gallons of wastewater per day. Due to the limited size of holding tanks, this wastewater must be discharged regularly. Current and anticipated regulations have fueled the need for shipboard wastewater treatment systems to ensure the biological oxygen demand and fecal coliform content of the effluent are below 25 mg/L and 20 cfu/100 ml respectively. Currently there are no effluent water quality sensors that are suitable for installation onboard a Military vessel. Fecal coliforms (FCs) are a class of bacteria present in feces. High levels of FCs in water provide a warning of a failure of the water treatment system and are typically correlated with the presence of pathogens. The standard method for FC determination is a bacterial culturing technique that requires a lengthy incubation period. Emerging “rapid” technologies require large and sensitive equipment and chemical labeling that are not suitable for Military deployment. The proposed research will develop an FC sensor that detects coliform bacteria providing a rapid, specific, robust, label-free, and automated detection system that requires little maintenance.

Title:Rapid Bioelectrochemical Monitoring Shipboard Effluent
Abstract:To address the Navy’s need for real time monitoring of organics in wastewater treatment systems, Lynntech proposes a microbial fuel cell based sensor for monitoring Biological Oxygen Demand (BOD) of shipboard effluents. The proposed sensor directly converts chemical energy of organic compounds from the wastewater into electric energy, which can then be correlated to the BOD content. It is expected that the sensor will accurately measure the BOD with response times of less than 1 hour, greatly reducing the time required compared to the conventional 5-day BOD method. By providing near real-time feedback about the performance of marine sanitation devices, crew members can adjust the treatment system’s operation and maintenance and prevent the discharge of insufficiently treated wastewater. The proposed sensor will include innovative design features to overcome technical challenges imposed by shipboard operations. Additional benefits of the sensor include its sensitivity to low levels of BOD, the potential for operation over extended time periods, ease of automation and low maintenance requirements.

Title:Microfluidic Sensors for Performing Real-Time BOD Measurements
Abstract:The proposed SBIR project addresses the U.S. Navy’s desire to confirm, in real time, the quality of effluents produced by shipboard wastewater treatment systems; thereby eliminating the time delay imposed by the universally accepted 5-day Biochemical Oxygen Demand (BOD-5) test that is used to legally validate the discharge of wastewater into the environment. At the present time, the 5-day time requirement of BOD-5 tests prevents Navy personnel from rapidly correcting problems with USGS certified Type II Marine Sanitation Devices that are being used to treat shipboard wastewater supplies. This requirement also makes it impossible to guarantee the water quality of shipboard wastewater discharges on a real-time basis during military operations. Due to existing/emerging environmental regulations that are focused on protecting the quality of global water supplies, the continued unavailability of real-time BOD measurements may eventually cause restrictions to military operations in littoral waters because of the limited capacity of shipboard holding tanks. The development/commercialization of the proposed microfluidic sensors, discussed herein, provides an innovative and cost-effective solution for estimating BOD-5 values within 5 minutes. Phase I objectives will focus on developing a new, innovative biocatalyst-mediated sensor combined with kinetic-based analysis algorithms for enabling the completion of real-time BOD measurements.

Title:SORDE: Special Operations Rapid Decision-making Environment
Abstract:As coordination and collaboration tools have become more sophisticated to support complex environments, research on tool-based interaction has become more crucial. Nowhere is the research more imperative than in military Special Operations, where effective collaboration in time pressured situations can mean the difference between success and catastrophic failure. Resilience to failure, disparities of tool availability, and distributed team members are a few of the many challenges to effective decision-making in time critical situations. SORDE, the Special Operations Rapid Decision-making Environment, is intended to support a program of operationally-relevant experimentation and application development that incorporates insight from the warfighter and knowledge of collaboration and coordination science. One particular experimental focus in Phase I will be the relative value of structured tools in comparison to more open-ended knowledge exploration features when supporting the warfighter. An enhancement to the current NAVAIR CORE testbed, SORDE will enable empirical investigation of issues critical to effective military collaboration, coordination, and communication. Existing metrics and tools will be incorporated into SORDE’s components. SORDE will then be used to prototype applications intended to support rapid decision-making in Navy Special Operations, enabling transition from the laboratory to the field.

Title:High Temp Standoff Dielectric Antenna Windows Based on 3-D Woven Preforms
Abstract:The speed of supersonic cruise missiles generates surface temperatures that can exceed the limitations of even high temperature structural metals like titanium. Insulation to protect electronics equipment in the missile is typically a parasitic thermal protection system. A multi- functional solution that has the potential of revolutionizing the design and performance of missiles, re-entry vehicles, and other hot flight structures is an oxide-oxide CMC based on a 3-D woven preform that integrates the thermal protection system. Structures based on oxide- oxide systems can withstand the anticipated temperatures of ~1200- 1500oF at lower cost than SiC-SiC. The 3-D fiber architecture will increase the fracture toughness and interlaminar strength of the CMC, while multi-rapier 3-D weaving enables the economical production of 3- D woven preforms and the integration of the thermal protection system. Further, the oxide-oxide systems of interest exhibit dielectric properties that make them of particular interest for antenna windows integrated into the vehicle skin. Therefore, the primary objective of the proposed program will be to develop capabilities to design, fabricate, and evaluate a new class of hot-structure panels that combine thermal protection and structural elements in a single integrally formed component for use as acreage surfaces and as antennae windows for supersonic missiles.

Title:Low Cost, Multipurpose Thermal Protection for High Velocity Missiles
Abstract:In future conflicts, it is projected that there will be a need for new weapon types that can strike targets around the globe within minutes. The development of high velocity (Mach 3 and greater), precision strike weapons is one response to the current need for weapon systems with the ability to attack time-critical targets at long range. In particular, precision strike missiles are being developed to meet the need for increased weapon effectiveness, decreased time to target, and increased fly out range. Future Navy requirements for precision strike missiles require advances in structural and insulation materials as enabling technologies. Such missiles will experience severe aero- thermal loading, high G accelerations, and must be capable of flight in all-weather conditions. It is clear that thermal protection materials will be required to ensure the successful integration of airframe components into precision strike missiles. We propose a novel, easily applied composite thermal barrier coating to meet the need for an effective, robust, non-ablating thermal protection material that can be applied using efficient manufacturing methods. This insulation coating has the potential to play a multipurpose role in precision strike missile thermal protection.

Abstract:The proposed program will develop a low cost, syntactic titanium foam sandwich panel outer layer encased with thermal sprayed thin tungsten layer for use as a insulation material in titanium sandwich panel structures for making dual functionality of thermal protection and structural capability of future missile integrated structural/TPS system. Based on previous program’s-conducted tests of thermal conductivity syntactic closed-cell titanium foam exhibits thermal conductivity less than 1/200th that of aluminum and about 1/20th that of solid titanium. Weight is 50% lighter than aluminum and 75 % lighter than titanium metal is a candidate material for future missiles integrated airframe/insulation structural system. Specifically, the innovation will demonstrate fabricating syntactic titanium foam sandwich panel by slurry cast titanium hydride encapsulated ceramic microspheres, drying, sintering, facesheet attachment and then encasing with a skin layer of tungsten by thermal spraying tungsten powders.

Title:Lightweight, High Temperature Beta Gamma Alloy/Process Development for Air Frame Structure Applications
Abstract:Gamma titanium aluminide alloys (gamma alloys) possess the attractive combination of low density (~50% of that of superalloys) and high temperature (up to 1500°F) capability, ideal for hot airframe structure and turbine engine applications. Yet, gamma alloys have not been inserted into aerospace service due to their material and manufacturing limitations. The primary limitations include processing difficulties, requiring costly non-conventional or multi-step processing requirements, and large lamellar grains, often leading to lowered damage tolerance. We have developed a new class of TiAl-based alloys, called beta gamma, which would remove or reduce such barriers. Unlike existing gamma alloys, beta gamma alloys are designed such that the ductile beta phase is adequate at elevated temperatures (for processing) but low or negligible at the anticipated use temperatures (for performance). The alloys also feature significant grain refinement and compositional homogeneity. This program is aimed to utilize such beneficial beta- phase distribution and microstructure features to develop the process technology to produce low-cost beta gamma alloy mill products such as thin sheets and rectangular bars with potentially improved properties. These low-density (4.1g/cm3) products are expected to be used at least up to 1300°F, showing application potential for airframe and engine structures.

Title:Enhancements for Lossy Optical Networks (EFLON)
Abstract:The US Navy has identified a need for optimized coding and protocols for free-space optical links. Such links provide the high bandwidth required by future service oriented networks in maritime and expeditionary environments. However, atmospheric turbulence and attenuation can have a deleterious impact on the performance of IP based communications operating on these networks. Architecture Technology Corporation (ATC) will leverage its extensive experience in network technology to develop Enhancements for Lossy Optical Networks (EFLON). These enhancements will alleviate the performance problems caused by atmospheric phenomenon, such as turbulence. The objective of this effort is to establish the feasibility of EFLON in Phase I. The follow-on Phase II effort will then implement a prototype of EFLON that will be demonstrated in a realistic environment.

Title:Optimized Coding and Protocols for Free-Space Optical Communications Links
Abstract:High-speed laser communications in adverse maritime conditions are necessary to transfer large amounts of data needed for command-and- control, target selection, or other intelligence. Atmospheric turbulence causes scintillation, variation of signal strength, and an increase in the bit-error rate (BER). Obscurations such as debris or fog cause scattering and a decrease in the signal and the information it contains. Conventional adaptive optics can be used to mitigate some of the turbulence effects, but data rates still need to remain high. In collaboration with our partner, the University of North Carolina at Charlotte (UNCC), we have recently finished some theoretical developments and laboratory demonstrations that will provide a novel optimized coding for the optical communications beam. Our coding scheme is based upon modulating a beam with an optical vortex with different vortex “charge” applied to each pulse. The pulse is then detected and the optical charge is determined. We can vary the vortex charge and thereby code each pulse with various values to increase the final data rate. The vortices placed on the beam are known to maintain their charge as the beam propagates through atmospheric turbulence, around small particulates (dust), and even fog.

Title:Star Tracker Augmented Inertial Navigation System for High Altitude UAV
Abstract:We propose to develop a low-cost, high-precision navigational sensor system for air vehicles flying at high altitudes and high Mach number that does not rely on satellite navigational systems. We plan to combine a low-cost inertial navigation system with one or more star tracking cameras to provide accurate positional data at high rates for extended periods of time. High altitude balloon missions have demonstrated that it is possible to acquire a sufficient number of stars for accurate attitude determination during daylight and nighttime hours. We plan to combine the highly accurate attitude information from the star camera with a star atlas and the INS to give optimal position estimates with near GPS accuracy. The navigation platform is completely passive and consumes little power. It enables high altitude air vehicles accurate navigation capability even during periods where GPS signals are unavailable due to enemy jamming or otherwise. With the advances in digital equipment, such as high resolution CCD devices, the cost of manufacture can be kept so low that our navigation system can be used on expendable weapons systems.

Title:Optical Celestial Navigation System for High Mach High Altitude Operation
Abstract:A navigational sensor system that can maintain an accurate position estimate without relying upon systems such as GPS, Galileo or Glonass is needed for a variety of military applications. Optical Physics Company is proposing to investigate a novel passive optical approach to build a modern day celestial navigation system (CNS) composed of (1) two star tracker modules and (2) a horizon tracker. The concept is elegant and sound, being based on a straightforward algorithm which locks celestial coordinates to an Earth-centric baseline. The proposed optical CNS will provide frequent updates to a low cost INS (inertial navigation system) which uses the 1 Hz CNS data in a Kalman estimator to provide 3 meter geo-location accuracy. During Phase I, we will develop an initial opto-mechanical design and perform a high fidelity simulation to evaluate noise and thermal effects. This will be followed by the design, assembly and test of one of the critical components, namely the horizon tracker. The other critical component, the star tracker is being developed under a parallel Phase II effort sponsored by the Air Force. Phase I Option work plan is to develop the Phase II prototype design for the optical CNS.

Title:High Mach, High Altitude Navigational Sensor
Abstract:Future weapon systems will operate for long durations at high altitudes and Mach number speeds. There exists a strong possibility that such air vehicles will not be able to rely on GPS during the entire flight path. For GPS denied navigation of high altitude air vehicles, a low-cost, high- precision navigational sensor system is required. We propose a novel approach that uses a passive optical Angles–Only Navigator to provide periodic updates to a low-cost advanced Inertial Measurement Unit (IMU) to correct for accelerometer and gyro drifts, and to maintain accurate flight trajectory. In the Phase I program, we will conduct a performance analysis and trade-off study for the optical sensor, analyze the IMU drifts and determine requirements for periodic updates using Angles- Only navigation, develop a navigation filter, perform proof of concept field demonstration using existing hardware and software, and develop a preliminary concept of Phase II prototype.

Title:Radio Frequency (RF) Modeling of Layered Composite Dielectric Building Materials
Abstract:The objective of this SBIR project is to develop a software tool for electromagnetic modeling of layered composite dielectric building materials as well as algorithms which would enable imaging through such structures by mitigating their image distorting properties. Two hybrid techniques are proposed for the calculation of the transmissivity matrix of complex, inhomogeneous, layered walls with arbitrarily shaped periodic inserts such as seen in rebar and cinder block concrete walls. The first method utilizes a 3-D volumetric integral equation using doubly infinite periodic dyadic Green’s functions. The second technique combines the results of periodic FDTD simulation of the unit cell with an iterative ray tracing algorithm to account for finite-size structures with edge and corner effects. We propose to build these tools based upon our EMCUBE software foundation, which is already equipped with full- wave FDTD and SBR ray tracing simulation engines.

Title:Radio Frequency (RF) Modeling of Layered Composite Dielectric Building Materials
Abstract:This SBIR Phase I project proposes to develop a system that will permit reliable RF detection of humans visually obscured behind non- homogeneous walls. It aims at accurate EM modeling of walls over the upper band of the UHF frequency range. The EM modeling results will then be used to devise algorithms to mitigate the wall dispersive effects that tend to obscure the EM signature of persons standing, sitting or kneeling behind the walls. Towards this end, recent advances in time- reversal, singularity expansion method (SEM), and statistical mutual information are considered as potential and viable solutions to unmask the human RF signature behind attenuative walls and walls with enclosed air gaps. The proposed research is hybrid between electromagnetic modeling and signal processing. Similarities and divergence measures are applied to signal returns for wall classifications. Transmitted pulse shaping and reshaping as well as linear processing of received signals are proposed to mitigate the wall effects and reveal human presence. Wideband beamforming implemented by an antenna transmit-receive array is used to provide three-dimensional imaging and to allow surveillance operations from desirable standoff distances. The proposed efforts involve verification of theoretical and computer simulation findings through experimentations and real data collection.

Title:Modified Polymer with High Permittivity for High Energy Storage Application
Abstract:New dielectric materials for large pulsed power capacitors that show good processability, high thermal performance (> 120C) and storage capability of more than 10 J/cc are needed for future naval vessels. Current state-of-the-art capacitors are polypropylene based and deliver 1 J/cc. Even though polypropylene has a low dielectric constant of about 2, the superior storage capabilities are due to its high breakdown voltage and low losses. In this Phase I SBIR project, Lynntech will prepare nanostructured ceramic/polymer composite materials through a simple and scalable solution casting process. Solution casting will offer the ability to pattern electrodes in selected regions with controllable thickness of surface materials and is a cost effective industrial process. On the other hand, the nanofiller and the polymer will act cooperatively to improve the dielectric properties of the composite material. The surface functionalization of an inorganic nanofiller, having high dielectric constant and low losses, will increase its wetability with selected polymer/copolymer host materials, leading to a solution cast composite with good uniformity, and improved dielectric properties. Due to the good delamination and dispersion of nanofiller within the polymer, only a very low loading (< 12%) of inorganic material will be needed to have superior storage capabilities.

Title:Development of Dielectric Films for Wound Capacitors
Abstract:This proposal addresses the development a high dielectric constant polymer films that will be used to produce self healing high energy density capacitors. The polymer dielectric is produced using a non contact method which results in defect-free, high temperature polymers that have an amorphous structure, high breakdown strength and low dielectric absorption. The complete metalized capacitor film will be produced in a one step roll to roll process with no handling or contact between the polymer formation and metallization steps. The polymer dielectrics can be formulated with a wide range of dielectric constants and thicknesses ranging from 100nm to 10+μm. The proposed development will focus in the formulation of polymer dielectrics with high dielectric constants which have been shown to have superior self healing properties, higher temperature capability and breakdown strength than conventional metalized film dielectrics. The capacitor film production process will incorporate a unique step that allows the formation of very thin corrosion stable, heavy edge electrodes, which are necessary for producing high energy density metalized capacitors. The phase one program will focus in evaluating the energy density of capacitors with high k polymers and different dielectric thickness. Deliverables will include 1ftx1ft capacitors and parametric data such as capacitance and dissipation factor as a function of temperature, dielectric absorption, energy density, and dV/dt charge and discharge characteristics.

Title:Development of Dielectric Films for Wound Capacitors
Abstract:We propose to develop advanced capacitor films with low-cost by modifying the current commercial capacitor films. The dielectric constant, energy density, and temperature stability of commercial capacitor films can be significantly improved by depositing a high- dielectric constant organic or inorganic dielectric coating using plasma enhanced chemical vapor deposition (PECVD) process. With proper composition design and careful tuning of the interface, the dielectric blocking layer can also minimize charge injection and leakage current so the capacitor charge-discharge efficiency can be improved too. The innovative capacitor film will have energy density higher than 10 J/cc, dielectric loss less than 1%, delivery rates faster than milliseconds, improved thermal performance above 120 „aC, and graceful failure feature. Furthermore, since no expensive capacitor film processing facility (> $25M USD) required, the high energy density capacitor film can be scaled up and produced with the well-developed roll-to-roll PECVD technology with low capital investment (< $2MUSD).

Title:High Energy Wound Capacitors Based on Flexible Oxide Films
Abstract:Compact, high energy capacitors that can store > 5J/g are required for next generation pulse power devices. Increase in energy storage of capacitors enables reduction in size of the capacitor banks. The key to reducing the size of these systems is to develop capacitors with much higher energy density (5-10 J/cc) than polymer film capacitors based on biaxially oriented polypropylene (BOPP, 1 – 2 J/cc) and ceramic capacitors based on BaTiO3 (0.1 J/cc). Current metal oxide or electrolytic capacitors produced by anodization of the metal (eg Ta) using liquid electrolytes or low conductivity electrodes such as MnO2 are limited in their operation above 10 kHz making them unsuitable for advanced high frequency (>100 kHz up to 100 MHz) pulse discharge applications. In this Phase I, TRS proposes to develop high energy density, pulse discharge capacitors (> 10J/cc) using amorphous metal (Ta, Zr, Nb) oxide thin films on metallized flexible polymer substrates (such as mylar and kapton).

Abstract:In this SBIR project we will develop an automated capability to quickly recognize and classify subjects in video imagery using soft biometrics. The system will have capability to translate video streams into probabilistic biometric metadata about the observed subjects (i.e. “With 82% confidence, subject is John Smith”). We intend to address both the accuracy and speed issues to produce a simple, intuitive and maintainable/upgradeable system which will allow real time and accurate searches of massive biometric archives. In essence our solutions will work by approximating the entire dataset in a small index which can be kept in main memory. At query time, this index is searched in milliseconds for an approximate answer, which is then confirmed by loading a small fraction of the original data from disk. A crucial observation is that if the index approximation has certain properties (the lower bounding lemma) we can guarantee that the result is the same one we would have gotten if we had done the slower brute force search. This system will allow for translation of descriptions of a person to a soft biometric metadata representation, allowing distributed and (possibly disparate) imagers to collaborate in inferring matches.

Title:Automated Entity Classification in Video Using Soft Biometrics
Abstract:With the growing concerns surrounding security and terrorism around the world, biometrics has become one of the premier solutions to combat these problems. Traditionally, biometrics has been an academic problem that has been studied from the perspective of optimal environments (good lighting, cooperative subjects, single-frontal-2D / 3D photographs, etc.) and unlimited time and processing power. In the real world, this is not the case. Today, even the most sophisticated identification algorithms can take up to 10 seconds to accurately identify a single subject due to the massive size of realistic databases (~1 million subjects). In this proposal, we present a variety of methods that will lower identification time by reducing the overall number of “possible subjects” through the use of Indexing and Soft Biometrics. Based on prior published experience in this area, we will evaluate the features that can be best used to categorize individuals into predefined bins (based on gender, skin color, height, weight, anatomical proportions, geometrical facial features, etc). Once identified, these features can be extracted from a video source and entered into a database for later use or can be specified a priori to locate subjects that match the given parameters.

Title:Automated Entity Classification in Video Using Soft Biometrics
Abstract:SET will identify and evaluate several gait- and face- based soft biometrics acquisition methods that are invariant to view points, range and illumination. This Phase 1 effort will focus on evaluating in-house software and newly developed algorithms to extract a number of soft biometrics from surveillance and other videos, demonstrate the potentials for reliable and fast retrieval and recognition of humans with matching soft biometrics signatures in reasonably unconstrained scenarios, and identifying technology enhancements for Phase II. The focus will be on evaluating the effectiveness of soft biometric signatures for different scenarios, depending on whether live visible or infrared video is available or a recorded video is being processed. We will analyze algorithms for determining the gender, height, cadence and stride parameters of the subject using gait analysis. When the subject’s face images are available, we will verify gender determined using gait, and determine the hair and eye color. By evaluating various soft biometrics extraction techniques using publicly available datasets, we will determine those that are most informative and better understand their working conditions. In Phase II, we will integrate a human authentication and verification system prototype for real time and automatic soft biometrics acquisition, indexing and retrieval functionalities.

Title:HTS Degaussing Cable Junction Box
Abstract:High Temperature Superconducting (HTS) cables offer major advantages over the conventional copper cables currently used to reduce the magnetic signatures of Navy ships. A degaussing system utilizing HTS cables would be smaller, lighter, and cost less to install than current systems. However, new components, cables and connection technologies are needed before HTS systems can be installed and operated in Navy ships. Creare is pursuing a development program to provide the Navy with the technology needed to transition an HTS Degaussing System into the next generation of warships. As part of this development effort, Creare proposes a High Temperature Superconductor Junction Box (HTSJB) that will provide electrical connectivity and cooling flow to HTS degaussing cables. Our HTSJB will incorporate quick disconnect connectors being developed on a separate project. Our design goals for the junction box are to minimize size and power, while maximizing reliability, durability and ease of installation. In Phase I of this project we will optimize the component configuration and complete an integrated design. Feasibility of the design will be demonstrated through an analysis of the component and overall system performance. In Phase II we will fabricate prototype junction boxes and demonstrate their performance in a degaussing system.

Title:Compact Cryogenic High Temperature Superconducting Cable Junction Box
Abstract:Future Navy combat ships, including CG(X) and related platforms will utilize an advanced degaussing system to reduce the hull magnetic signature. High temperature superconducting (HTS) cables are being considered by the Navy for the advanced degaussing system, because of the potential for significant weight, installation cost and operations cost reduction. In an ongoing Navy sponsored SBIR effort, the Tai-Yang Research Company is developing a quick disconnect terminal fitting that simultaneously makes electrical and cryogenic connections to an HTS degaussing cable. The proposed junction box will be based on TYRC’s proprietary connector design, and will include features to route cryogen from the cable to the cooling and circulation system, and connect the superconductors to an external power supply, in a compact module that minimizes system heat load. In Phase I, TYRC will explore design options for integrating the cryogen cooling and circulation system components, TYRC connectors and electrical feedthroughs in a common vessel. Alternative configurations for remote service connections or shared services among multiple cables will be considered. In Phase II, TYRC will build a prototype junction box and evaluate its performance under conditions relevant for Navy shipboard application.

Title:Autonomous Collision Avoidance and Separation Assurance for Small UAVs Operating in the National Airspace System
Abstract:Unmanned air vehicles (UAVs) are presently restricted from operating within the vast National Airspace System (NAS) covering most of North America. The proposed effort seeks to develop FAA-certifiable collision avoidance and separation assurance algorithms that guarantee safe interoperation of small UAVs and other aircraft in the NAS. Small UAVs pose additional size, weight, and power (SWaP) limitations that make this problem especially difficult. The proposed effort adapts and integrates two novel technologies. A rapid collision avoidance algorithm first developed by MIT for unmanned ground vehicles is adapted and unified with an efficient hybrid D* path re-planning algorithm developed previously by the authors. These technologies are chosen specifically for: (1) their robust real-time performance using very limited computation; (2) their accommodation of substantial sensor, disturbance, and modeling uncertainty; and (3) their generation of maneuvers that are guaranteed to be dynamically feasible. The proposed concept is designed to handle dynamic obstacle aircraft that may or may not be cooperative or well-sensed. Because the collision- avoidance and path-planning components both generate complete, realizable trajectories (rather than waypoints), tracking errors can be bounded and aircraft separation can be assured with the highest levels of confidence.

Title:Autonomous Guidance for Unmanned Aircraft Operating in National Airspace
Abstract:This document proposes to develop, test, and demonstrate collision avoidance and autopilot guidance algorithms for small unmanned aircraft systems. This project will develop real-time, multithreaded algorithms that will process sensor inputs, manage priorities, plan aircraft trajectories, and generated autopilot inputs. The project will also involve an extensive modeling and simulation effort, in order to perform tests and demonstrations of the algorithms developed. The resulting simulation capability may also be useful for testing alternative algorithms, and for developing and refining system requirements and specifications. UAVs with autonomous capabilities are essentially flying robots. As robots, they need to gather information (sensory input) about the environment around them and make decisions about what they should be doing (controlling actuators or devices). Sensors and devices must be dealt with concurrently, otherwise devices can get starved and sensors ignored. The software design is patterned after the latest generation robotic software. To support testing and validation, a simulation testbed based on the USAF EAAGLES toolkit will be used. This will allow testing in a high-density environment. EAAGLES was built to support distributed simulation so that many EAAGLES-based applications can be executed simultaneously thereby generating many players without compromising performance.

Title:Biologically Inspired Reconfigurable Computer for High-speed Object Avoidance in Small UAVs
Abstract:For this project, we plan to collaborate with researchers in the neuroscience department at the University of Delaware to develop an FPGA-based embedded computer, inspired in the brains small vertebrates (fish). The mechanisms of object detection and avoidance in fish have been extensively studied by our Delaware collaborators. The midbrain optic tectum is a biological multimodal navigation controller capable of receiving input from all senses that convey spatial information, including vision, audition, touch, and lateral-line (water current sensing in fish). Unfortunately, the complexity of these models makes them too slow for real-time implementation. These simulations are run offline in state-of-the-art desktop computers, presenting a gap between the application and the target platform: a low-power embedded device. EM Photonics has expertise in development of high- performance computers based on commodity platforms such as graphic cards (GPUs) and FPGAs. FPGAs offer (1) high computational power, low power consumption and small footprint (in line with typical UAV constraints), and (2) the ability to implement massively-parallel computational architectures, which can be leveraged to closely emulate biological systems. Combining UD’s brain modeling algorithms and the power of FPGAs this computer will enable navigation in complex environments, and further types of UAV onboard processing in future applications.

Title:Autonomous Guidance for small UAV Safe Flight Operations in the National Airspace System (NAS)
Abstract:Safe flight by Unmanned Aerial Vehicles in unrestricted airspace, including the National Airspace, will only be possible with effective and reliable Sense and Avoid technologies and techniques. Several projects, including four Office of Naval Research STTR's, are underway to develop sensors capable of addressing the first aspect. Latitude Engineering, LLC proposes to address the second aspect using modern control methods to design and analyze a collision avoidance control algorithm that will first assure minimum separation distances are maintained, and second, will avoid a collision, should a dangerous situation arise. Our approach uses differential game theory to develop well-defined zones of complete or partial safety to analyze the volume around the UAV and the performance of the control law. The algorithm will be capable of effective avoidance using sensors of different performance characteristics, including those that output only bearing information, such as acoustic or optical sensors, or complete relative position, such as radar or ADS-B. In addition, the control law will be designed so as to balance the requirements of safe flight with needs of the mission.

Title:Strongly Bonded Heavy Reactive Metal Composites
Abstract:The Navy has a need for high density composites for advanced warheads. Billets of a heavy metal combined with a reactive metal have shown promise. However, the materials demonstrated to date have been lacking in density and strength. This proposed Phase I program will build on the success MER has had in developing composite penetrators for the Air Force which combine a heavy metal such as Ta or W with a reactive metal such as Zr. The resultant materials have demonstrated a combination of high density, reactivity, and high strength in gun launch and explosive launch testing. Composites will be made in compositions specified by the Navy using a low cost rapid manufacturing process which is in place at MER.

Title:Novel Processing for High Density Metal-Metal Composites
Abstract:Materials and Manufacturing Systems (MATSYS) proposes to develop novel processing technique for metal-metal high-density reactive composites for the enhancement of new warhead concepts. This effort will combine our unique expertise in instrumented-Hot Isostatic Pressing (HIP) with new approaches in intermetallic design to develop a new generation of cost-efficient, high-density, high strength reactive composites. The proposed material system will use a blend of two elemental powders which can yield a fully dense composite with a density of 5 to 8 g/cc. The powders will be consolidated to full density to maximize the load-carrying capability of the composite, including strength and ductility. The consolidation will occur below the reaction initiation temperature to prevent any energy release during compaction. The existence of two different powder materials will allow for tailoring of the mechanical and reactive properties of the material by varying the volume fraction of each element. High-energy milling will be used to achieve a homogeneous structure within the powder. Upon successful demonstration, this powder-based process can be easily applied to different powders, including tri or tetra components systems, and scaled for cost-effective, high volume production of powders and fully dense composites.

Abstract:This SBIR Phase I effort examines the feasibility of producing metal- metal high density composite materials with sufficient strength to survive severe shock through mechanical deformation. As with many advanced materials, a critical obstacle to their implementation is very high manufacturing costs, particularly for the starting master alloy billets. To surmount this cost barrier, this Phase I program will examine an innovative, yet affordable and relatively simple mechanical deformation production technology based on compacting and deforming the elementals through step by step processes such as forging and extrusion.

Title:Exploitation of Network-Based Information
Abstract:The transition of Department of Defense (DoD) infrastructure to a Net- centric Enterprise Services (NCES) architecture on a Global Information Grid (GID) is dramatically increasing the connectedness between military, civilian, and intelligence personnel and the networks they employ. With the continued adoption of networked technologies by the DoD and adversaries, it is imperative to simultaneously research and develop technology that can provide insight into the complex behavior of these networks, so as to better understand, protect, defend, monitor, and exploit the networks for strategic goals. Novel contributions are crucial in the growing field of network science that can provide rapid insight into complex behavior of GIG-NCES networks. Toward this end, 21st Century Technologies (21CT) proposes NetMetA, a solution that provides network metric analysis capabilities applicable to the sensor, computer, human communications, and intelligence networks of the GIG. Links within GIG (communication) networks are far from simple, varying over time in the communication frequency, duration, and quantity of information exchanged. NetMetA specifically considers these critically important aspects of communication links in seeking to 1) extract relevant metrics of communication activity, 2) classify the behavior of network entities and their relationships according to common profiles, and 3) identify and measure global communication pathways.

Title:Detection and Tracking on Dynamic Random Networks - MP 140-07
Abstract:We propose to develop a theory of detection and tracking on dynamic networks which harnesses rigorous mathematics to address the concerns of network analysts. The mathematical and operational communities are currently disconnected -- the network analyst employs unsophisticated technology, and the mathematician finds little of interest in the analyst's needs. We propose to bridge this culture gap by formalizing the analyst's needs in the rigorous language of detection and tracking theory, and then establishing a new field of study which will provide solutions for the analyst while being mathematically stimulating enough in its own right to attract researchers to solve these problems. The focus of the proposed Phase I work is the development of a theory of dynamic random graphs analogous to the well established static case, and the demonstration that the theory developed lays a foundation for the overarching goal of a detection and tracking theory on dynamic networks.

Title:Multi-scale Dynamic Network Graph (MUSING) for Network-based Information Exploitation
Abstract:As previously dispersed information or entities become more and more connected, they form increasingly complicated networks and result in complex interactions. The benefit of an interconnected network is that since the information in the network is related in some fashion, information can be exploited to extract latent behaviors or trends of the network which would otherwise be missed if the information is viewed in isolation. We propose the Multi-scale Dynamic Network Graph (MUSING) model to encode, infer and predict the status of dynamic networks by fusing distributed observations (networked data) in the presence of noise or uncertainty. The model structure takes advantage of natural clustering of many networks to facilitate its temporal evolution. The architecture of the scale and time interactions in the MUSING model is particularly amenable to efficient propagation of information. Furthermore, due to the scale nodes in the model, large-scale behaviors and trends of the network are readily available, which offers additional insight into the network status, in addition to the individual nodes.

Title:A General Purpose Toolkit for Exploiting Network Data in Diverse Applications
Abstract:Stottler Henke proposes to develop a generalized toolset around a new and innovative network data encoding strategy with the goals of: (1) increasing the scalability of network analysis and visualization tools; (2) fundamentally improving the intelligibility of network models and thereby increasing the accessibility of network science to the broader research community; and (3) providing a more faithful representation of reality in situations where generic modeling approaches may obscure or misrepresent system dynamics and engineered functions. The proposed system, called NetSet, will be comprised of three primary components. First, it will provide the capability to automatically identify recurring and meaningful structures (e.g., Motifs) within complex networks in order to improve the scalability, accuracy, and exploitability of network models. Second, NetSet will move beyond the typical unimodal (i.e., nodes and links) representation and capture broader descriptive features. Last, the proposed system will bridge the current gap between traditional network science and Statistical Relational Learning so as to support a broader range of predictive analysis applications. Our Phase I prototyping will prove the feasibility of our approach and set the stage for the complete implementation of NetSet in Phase II and its subsequent commercialization.

Title:Team Knowledge Interoperability in Maritime Interdiction Operations
Abstract:We develop a same time/different place collaborative ability to promote shared awareness in teams working in rapid response operations with fluid and rich data. Our goal is to better understand cognitive processes of team collaboration, and use the understanding to drive the design of a collaborative system (CS). The CS is targeted to Maritime Interdiction Operations (MIOs), but also applies to emergency responders. Our solution defines schemas for MIOs. Schemas are the antithesis of task models – they don’t say how to do the job, but instead focus on assumptions and responsibilities by role for the MIO, which are easier to elaborate than listing all possible tasks and decisions. When an assumption goes wrong on a MIO, improvisation is required which invokes collaborative problem solving. We use a cognitive model to describe collaborative events that the CS initiates when assumptions are violated during a MIO. The CS also acts as a memory aid to help MIO team members invoke knowledge they already have, and perform better. After a MIO, schemas are updated through reflection to dynamically evolve as teamwork evolves and enemy tactics adapt. Phase I empirically assesses deriving and updating schemas, and creates a preliminary CS design.

Title:Team Knowledge Interoperability in Maritime Interdiction Operations
Abstract:Navy operations such as Maritime Interdiction Operations (MIOs) are increasingly composed of distributed assets that interact and collaborate over great distances. Not only must fielded assets coordinate information and actions, but reach-back assets that perform analysis functions play an increasingly large and common role. The collaboration tools that are in use today fail to meet many of the collaboration and cognition needs of users. In terms of recent models of team collaboration and knowledge interoperability (Warner, Letsky, & Cowen, 2005), these tools offer little explicit support for knowledge building, problem solving, or consensus building. We proposed to develop a tool called HERMES. The communication-collaboration tool will support team situation awareness and incorporate mixed-media messages and explicit design structures to support collaboration and knowledge interoperability within the MIO task environment. The tool is based on SLATE wireless collaboration technology. Along the way of developing the HERMES tool, the project will delve into the cognitive/collaborative activities of MIO team members in order to better understand these activities and how to better support them. In particular, the requirement of providing explicit interface designs to support collaboration will entail research into the macro-cognition and knowledge interoperability needs of these users.

Title:Rapidly Tunable Niobium Notch Filters
Abstract:A major problem limiting broadband digital receivers is the presence of interference signals that saturate the analog-to-digital converter (ADC). This problem can be alleviated using analog notch filters that block these interferers before digitization, provided the notch filters can be adaptively tuned to follow rapidly shifting interferers. Superconducting thin-film filters offer superior notch rejection combined with little insertion loss outside the notch. HYPRES has developed a superconducting broadband digital-RF receiver mounted on a reliable 4K cryocooler. It is natural to combine this niobium (Nb) digital technology with a Nb-based superconducting filter technology, since they can readily be fabricated and integrated together into the same cryogenic assembly. HYPRES proposes to design, simulate, and eventually fabricate and test filter banks consisting of multiple Nb notch filters, which may be rapidly tuned across the relevant RF band. This will be carried out in collaboration with the University of Waterloo. Tuning mechanisms will be based on either of two approaches: current-biased Josephson junctions, and voltage-biased microelectromechanical (MEMS) capacitors. It is anticipated that both approaches may lead to high-Q notch filters in the 2 GHz range that may be tuned ~20% on microsecond times. The filters will also be examined for linearity and power-handling.

Abstract:In this program, we will develop a concept for microsecond tuning notches meeting the notch depth and insertion loss requirements of the application. We will define a full set of target specifications for the tunable notches that meet a current or future operational need. We will demonstrate through simulation that this technology can be used for microsecond tunable narrowband notch filters with minimal insertion loss. We will then design and optimize a resonator to minimize the size, maximize the Q (hence minimizing passband loss) and the tuning range, and optimize the precision in Phase II. We will then outline the technical risks for Phase II. Successful completion of this effort will form a solid foundation for building and testing a prototype tunable filter in Phase II.

Abstract:To address the Navy¡¦s need for tunable UHF filters with a low insertion loss and fast response time for various radio systems in the JTRS program, Physical Optics Corporation (POC) proposes to develop a new, oxidized, macroporous, silicon-based tunable filter (OMPSi TF). This proposed filter utilizes a low-loss OMPSi plate to support a thin quartz plate with the stripline electrodes pattern, and to confine the shunt electrical discharge within its microchannels. The innovative use of micromachined material will enable the filter to be switched in less than 3 microseconds between ~80 digitally controlled frequency bands within the specified range, while providing an insertion loss of below 0.5 dB in the center of the transmission band. In Phase I, POC will demonstrate the feasibility of OMPSi TF by designing the filter prototype and fabricating the fully operational filter, utilizing established OMPSi manufacturing technology. In Phase II, POC plans to optimize the filter operation parameters to guarantee its fast implementation into military communication equipment.

Title:Rapid Identification of Asymmetric Threat Networks from Large Amounts of Unstructured Data
Abstract:21st Century Technologies (21CT) proposes PRESAGE, a fast, mobile, and robust computational tool for automated analysis of extremely large sets of unstructured information to assist commanders in proactively responding to asymmetric threats. Understanding and influencing the sympathies of the populace is an important tool in counter-operations against asymmetric threat. Yet, strong indications of the attitudes, sympathies and hostilities within the populace often go unexploited. There is a vast amount of data that is available on the internet in unstructured form, for example, in the form of blogs. However, this data is currently untapped due to the intractability of using traditional, linear computational or manual methods on datasets of this magnitude. Commanders require new, innovative solutions that can digest this wealth of information and rapidly provide assessments of the threat presented to friendly forces by belligerent elements of the indigenous population. PRESAGE provides a novel solution to process the immense and continually expanding quantity of available data.

Title:Rapid Identification of Asymmetric Threat Networks from Large Amounts of Unstructured Data
Abstract:The asymmetric adversary the U.S. faces today and in the foreseeable future is radically different from previous adversaries and must be thought of in an entirely new light. As events in Afghanistan and Iraq illustrate, warfare is being transformed from a closed, state-sponsored affair to one in which adversaries operating in small, agile, and distributed cells can declare war on nations. Gathering, translating, and analyzing intelligence on these adversaries has proven difficult due to their use of unstructured open source information, which has exponentially increased the burden on intelligence analysts. Securboration, teaming with Dr. Yaneer Bar-Yam from the New England Complex Systems Institute (NECSI), proposes an innovative solution, referred to as Open Source Monitoring System, or OSMOSYS. OSMOSYS leverages Securboration’s powerful semantic modeling techniques to effectively normalize OSINT input streams and uses a technique patented by Dr. Yaneer Bar-Yam that subdivides neural networks in a manner similar to physiological systems. The result is a system that generates warnings and actionable intelligence from OSINT that allows friendly forces to operate inside the observe-orient-decide- act, or OODA, loop of asymmetric and irregular foes thus depriving them of the initiative and forcing them into reactive modes.

Abstract:Given the evolving risks posed by irregular adversaries, we must consider a wide variety of strategic and tactical threats beyond suicide bombers and improvised explosive devices. In order to mitigate these threats we must dramatically improve our ability to draw predictive value from the massive volumes of available unstructured open source intelligence (OSINT). We propose to develop Propheteer, a system that will be capable of rapidly processing that data to predict trends in at risk populations and threat levels. Our approach fully exploits the unique capabilities of a particular form of recurrent neural networks called Long Short-Term Memory (LSTM). The primary strength of the LSTM model is its ability to efficiently uncover patterns in complex temporal data. We also recognize that the success of Propheteer will be largely dependent on the numerical reduction of the complex and voluminous OSINT. A major contribution of this effort will be the extension of our topic tracking tool to automatically identify sequences of reports held within unstructured data archives. These sequences will provide Propheteer with essential temporal training data centered on an event of interest and extending both backwards and forwards in time – without incurring the high costs of extensive manual tagging.

Title:Shock and Vibration Tolerant High Temperature Superconducting Shipboard Degaussing Cable
Abstract:In the proposed SBIR Phase I project, American Superconductor Corporation (AMSC) will carry out an extensive industry “best practice” exercise to optimize a high temperature superconductor (HTS) degaussing cable design to meet U. S. Navy (USN) shock and vibration requirements. The materials specification will indicate cable geometry; insulation, overwrap and core materials for typical applications as specified by USN sponsors. The process specification will define a manufacturing process map of the optimum design. AMSC will produce a small prototype (1' long) cable as a Phase I deliverable. AMSC will ensure a preliminary integration of a USN designated quick-disconnect connector with the HTS cable. A “gap analysis” will be performed to finalize the HTS cable to quick-disconnect connector integration. AMSC will define HTS degaussing cable condition based maintenance parameters by identifying, investigating and determining measurements as required in a full laboratory demonstration based on USN guidance. During Phase II, the HTS degaussing cable design chosen in Phase I will be manufactured in a length to be determined and tested for shock and vibration to MIL-STD-901 and 167, respectively.

Title:HTS Degaussing Cable
Abstract:High Temperature Superconducting (HTS) cables offer major advantages over the conventional copper cables currently used to reduce the magnetic signatures of Navy ships. A degaussing system utilizing HTS cables would be smaller, lighter, and cost less to install than current systems. However, new components, cables, and connection technologies are needed before HTS systems can be considered for installation and operation in Navy ships. In particular, there are no suitable HTS cables currently available for this application. HTS cables being developed for electricity transmission have different voltage, insulation, and cooling requirements. Creare is pursuing a development program to provide the Navy with the technology needed to transition an HTS Degaussing System into the next generation of warships. As part of this development effort, we propose to develop an innovative HTS degaussing cable, in which up to 40 HTS conductors are installed in a flexible cryostat that is terminated with quick disconnect couplings. In Phase I of this project, we will develop a cable design and demonstrate that it will meet the Navy’s requirements for this system. In Phase II we will fabricate full-length prototype cables using production fabrication techniques and demonstrate their performance in a degaussing system.

Title:Dynamic Parameters for High Speed Craft Composite Component Testing
Abstract:The dynamic characterization of polymer composites is becoming an increasingly important USN topic. As the Navy moves towards increased construction of composite high-speed craft, it becomes very important to have a complete understanding of their strength, stiffness and durability in such environments. This requires a proper composite materials database. The parameters necessary to deduce methods for the required tests have yet to be determined. Once they are, the test methods and equipment needed to produce the database could be designed. Impact Matrix Systems, LLC has a large database defining the response of a broad range of composite materials to the high strain rate impact events typically encountered by high-speed craft. Its source is a seven-year test program executed in conjunction with a major US producer of high-speed craft. The information includes high rate strain and accelerometer data. IMS has outlined a comprehensive Phase I project for the development of the required strain event definitions and test methodology. IMS will employ its combined internal and affiliate expertise to deliver an effective combined solution. Successful proposal execution proposal will provide benefits to the USN in the form of lighter weight, lower cost and more predictably durable composite craft structures.

Title:Design and Validation of Standardized Wave Slam Test Equipment and Time-Temperature Superposition Procedures
Abstract:Wave slam loading on hull structures are characterized by a rapid rise to a very high peak pressure, followed by a slower drop to a longer duration, lower pressure. An event can be as short as 10 msec, with a 200 psi peak pressure. Loads of this type are known to be a major consideration in the design of composite high speed hulls, but to date no efficient method for testing panels in a laboratory with a properly simulated loading has been developed. KaZaK Composites proposes the design, development and demonstration of a novel test method capable of rapidly loading multiple composite panels with an accurate simulation of wave slam pressure-time pulse. KaZaK’s system will feature multiple panels loaded at the same time, as well as provisions to incorporate accelerated aging technology to further reduce test time. We will work with a commercial boat builder with industry-leading slam test experience, as well as a world–renowned composite test expert to ensure that our evolving test process far exceeds current state of the art. Our Phase I program will conclude with hardware demonstration of the test procedure concept. The ultimate objective will be ASTM certification of the proposed methodology.

Title:Next-Generation Mobile Software Defined Radio
Abstract:Mobile Software Defined Radios (SDRs) of the future will require wideband capability, complete radio reprogramability, and the ability to function in the mobile, low power environment. To meet these sometimes conflicting requirements innovative components will need to be integrated into innovative architectures. Systems offering these capabilities today are large form factors that typically do not contain true “reprogrammable radios”. Aeronix proposes to take an existing design for a small low power software reprogrammable radio and modify it’s “fixed radio” areas to enable a true “SDR” design for mobile handhelds. Aeronix has a current radio that is designed for low power, high performance, and software reprogramability. The radio consists of a SOC processor and DSP, an FPGA, and a fixed frequency radio. Aeronix will replace the fixed radio block with a broadband RF SOC (Aeronix has formed relationship with a large OEM and has approval to use SOC in designs) and MEMS front end filters. This new design will be modeled based on SCA and GLOMO API definitions that will also serve as a waveform development environment.

Title:Next-Generation Mobile Software Defined Radio
Abstract:The U.S. military’s next-generation radio system, Joint Tactical Radio System (JTRS), is based on Software Defined Radio (SDR) technology and will create new opportunities, methods, and applications for generating and sharing tactical data. One of the many challenges in realizing the JTRS vision is to create small, lightweight, embeddable devices that operate from battery power, meet the requirements for performance, SCA compliance, and can be carried, worn, or embedded for mobile applications. DataSoft will identify the most promising available approaches for the development of low-cost embeddable software defined radios (SDR) that minimize power consumption and maximize battery life. This will be accomplished through the quantified evaluation of current and future SDR components and technologies. Our Phase I activities will develop a SDR architecture which incorporates available best-of-breed technologies from both commercial and Government sectors to produce an embeddable low-cost, small size and weight, low power consumption SDR device composed of commercially available components, that can take advantage of the JTRS software communications architecture (SCA) and software waveform library.

Title:Universal Air-to-Ground Broadband Networking Communications Waveform
Abstract:Modern military in-theater tactical and emergency communications would benefit greatly from an ability to communicate among all service platforms, but no common waveform standard currently exists to support this. Ideally, such as waveform would fully leverage the higher bandwidth connectivity capabilities inherent in aircraft-to-ground communications, while preserving the capabilities of current terrestrial waveform standards. These operational settings are very challenging for wireless communications because the waveform must simultaneously be robust to multipath and the associated signal fading and inter-symbol interference, and to Doppler shifts typically encountered with air platforms. In this effort Toyon proposes to develop a waveform standard capable of adequately meeting these divergent requirements, as well as developing the associated software and hardware to demonstrate these capabilities. For this purpose we pursue a technical path focusing on orthogonal frequency-division multiplexing (OFDM), which combined with the spatial diversity benefits inherent in multiple-input and multiple-output (MIMO). At the successful completion of this Phase I effort, Toyon will provide real-world demonstrations of the technology and work with the Navy to select a final system to which to target development in a potential Phase II.

Title:Multimedia over highly dynamic mobile wireless ad hoc networks: A cross layer collaborative approach
Abstract:A novel framework for multimedia communications over highly dynamic MANETs is proposed. The proposed framework is model-based and has many virtues such as scalability, self-organization, and self-healing, just name a few. To develop such a framework, significant theoretical and simulation efforts need to be made in cross-layer optimization, multipath routing of multimedia over the low-bandwidth MANETs, and performance evaluation. In our approach, we propose a novel cross- layer optimization approach to take QoS into account at MAC, network, transport, and application layers for multipath routing of multimedia over MANET; A Multiple Description (MD) coding technique will be integrated to offer great potential for video communications over military MANETs under extreme conditions. A novel model-based simulation infrastructure with an integrated executable modeling solution across multiple design abstraction layers will be built to facilitate the operational specification, design, and development simulation of the class of content-driven distributed applications. Finally, a video quality evaluation framework will be developed to efficiently assess the quality of transmitted video based mainly on frame decoding errors.

Abstract:nanoPrecision Products (nPP) proposes development of a new family of miniature hybrid fiber optic/electrical connectors for Navy and commercial applications by utilizing a proprietary nano-scale metal stamping process which can achieve nanometer scale tolerances with high repeatability and very low cost. This process can manufacture revolutionary low cost, high density metal termini transmission solutions for either fiber optic or electrical signals. Moving away from traditional, off-shore sourced, ceramic fiber optic termini enables a change in fiber optic termini design rules toward more compact fiber optic termini form factors. nanoPrecision Products is pioneering the development of a nano-precision stamping process for metal components with a goal of ± 100 nm form tolerances by combining deterministic micro-grinding (DMG) with computerized modeling, metrology, and optimization of fundamental process materials and mechanics – no such capability exists today.

Title:Miniature Robust Hybrid Connector
Abstract:To address the Navy’s need for a miniaturize hybrid fiber optic/copper circular connector for use in the Buoyant Cable Antenna (BCA) System, Physical Optics Corporation (POC) proposes to develop a new Miniature Robust Hybrid Connector (MiRHyC). This proposed hybrid connector is based on proprietary non-imaging optics and an advanced mechanical package. The innovative connector design will enable the MiRHyC to offer robustness, making it insensitive to mechanical shock and vibration and relaxing alignment requirements. Use of innovative modular inserts and a miniature fiber connector assembly offers increased contact density while providing the BCA designers flexibility in using different combinations of electrical and fiber optic contacts. This connector will have a rigid section outer diameter (OD) of <0.625 in. and mated length (excluding strain relief) of <1.25 in. and will be waterproof to a pressure of 1,050 psi, and have mated tensile strength of 350 lb. In Phase I, POC will demonstrate the feasibility of the MiRHyC by designing and testing a Technology Readiness Level (TRL 4) prototype. Finite element modeling (FEM) and solid modeling will be used to validate this design. In Phase II, this prototype will be optimized and upgraded to achieve a high TRL of 6.

Title:Middleware Specification for Low-Power Distributed Processing Devices
Abstract:The DataSoft Small-form factor Power management Middleware (DSPM) solution provides a new portable cross-cutting way that existing solutions can be unified in a single power context. This is characterized by a middleware abstraction layer where software components can either actively themselves manage energy use or be managed by a higher order power management service. In this way, components and clusters of components can be power managed using a policy and profile based approach in which the overall power management function is a collaborative effort by multiple software and hardware component elements working together to enforce a policy. DSPM identifies power conservation states (via a state machine) and a way to specify and enforce a series of power loci or threads of execution across the device hardware and software via a context that aims to minimize cycle count. This is done via a set of interfaces that define a Power Management Service whose objective is to direct all power managers in the lower software and hardware layers to work collectively. DSPM enforces a distributed power management strategy via a strategy based on user profile, context and specifiable policy together. DSPM model will enable SDR designers to stipulate constant minimal power execution strategy across disparate processors and software stacks.

Title:Middleware Specification for Low-Power Distributed Processing Devices
Abstract:Power usage is of special engineering concern for hand-held devices. The migration of much of the signal processing to software in Software Defined Radios has shifted power concerns from specialized signal processors to more general-purpose computing elements. The power needed is determined by the power of the CPU used and the size of the memory required. In turn, the power requirements and memory requirements are determined by the processing requirements of all layers of the software infrastructure: the software application, the middleware, and the operating system. This proposal focusses on the contribution of the middleware and proposes the development of a new specification for middleware for low-power devices. Changing contexts, such as power conservation requirements, demand re- examination of the engineering tradeoffs made in the previous generation of devices. The development of the new specification requires a deep, clear, metric-based understanding of the current state of technologies, as well as a vision of how a new technology will reach new market segments while serving the interests of existing technology users.

Title:Low-Overhead Software Communications Architecture ( SCA) Core Framework (CF) for Small Form Factor (SFF),Low-Power Software Defined Radios (SDRs)
Abstract:The Software Communications Architecture (SCA) defines an architecture for a common radio system infrastructure. This infrastructure or Core Framework provides the management and control capabilities for a radio system. However, many SCA projects have resulted in large, monolithic implementations that do not scale well across a range of radio systems. Thus, it has not been successfully applied to Small Form Factor (SFF) radio systems that have stringent Size, Weight and Power (SWaP) constraints. Objective Interface Systems believes that the fundamental architecture defined by the SCA specification is valid and that a different perspective on the design and implementation is necessary to achieve deployment of the SCA across a wider range of platforms. Coupled with innovative technology for automated removal of unreferenced code and modular deployment architecture, this SBIR project will identify specific driving requirements for SFF radio systems. Specific design and implementation optimizations will be identified together with anticipated improvements. Several of these optimizations will be implemented to gather quantitative data on the benefits of the approach. The result of the Phase I effort will be a comprehensive plan for an SCA core framework implementation that both meets the SCA specification and the deployment profile demands of the SFF radio.

We propose a low-overhead, high performance implementation of the SCA Core Framework, the set of interfaces used directly by SCA-compliant applications, that requires only slight restrictions on the full SCA functionality which are not likely to be relevant to the handheld and manpack JTRS platforms targeted for this variant of the core framework.

Abstract:Mayflower Communications Company, Inc. (Mayflower) proposes a co- site interference mitigation product, Guardian, to meet the Navy objectives, namely, develop and demonstrate techniques to mitigate the impact of unintentional interference in the VHF and UHF communications bands caused by high-power transmitters located in close proximity to the communicator. The proposed Guardian can be unobtrusively integrated with the radios such as SINCGARS, EPLRS and JTRS for protection from co-site interference, such as EW Jammer. Guardian functionality can also be incorporated in JTRS radios to reduce the interference levels across the network and in future EW jammers to solve the interference problem at the source. The proposed Guardian product leverages Mayflower’s expertise in anti-jam, and builds on technology developed under several SBIR programs and Internal R&D. The Guardian co-site interference mitigation product, when proven feasible in the Phase I study for the Navy application, has enormous potential for military and commercial applications. In Phase I and Phase II, Mayflower will develop and demonstrate a cost-effective Guardian prototype. In Phase III, Mayflower will ensure further development and commercialization of Guardian.

Title:Magnetic Rubber™ Coatings for High-Strength Optical Fiber Communications Lind Payout Cable
Abstract:This program would develop high-strength, low bendloss singlemode optical payout fibers with Magnetic Rubber™ coatings, and magnetic mandrel bobbins, for high speed underwater communication data links. Unlike conventional fiber-wound bobbin designs, magnetically-coated optical fiber and a magnetic mandrel offer improved performance during payout at practical vehicle speeds. This is because the magnetic field of the bobbin can be tailored as a function of length, thus allowing an opportunity to reduce fiber stress maxima that occur cyclically during payout. During Phase I, NanoSonic would theoretically analyze the magnetic fields, resulting magnetic forces and fiber stress produced during payout for magnetically-coated payout fiber on a magnetic mandrel of controlled properties. One kilometer test lengths of low bend loss singlemode fiber with magnetic coatings designed to allow attachment to the mandrel would be fabricated and wound in prototype bobbin geometries. Fiber stress during simulated payout would be measured directly, and experimental results compared with analytical values. Phase II would build on the demonstration of magnetic coating production and initial payout results, to improve coating properties and winding and payout designs. NanoSonic would work with a major contractor responsible for the manufacturing and deployment of high speed underwater fiber communications hardware for the Navy.

Our goal for the Phase I project is to develop and finalize a design for a fully automated, multi-fiber pack winding machine, as well as to optimize the fiber length, strength, and wind quality through careful design optimization of the fiber pack spindle and possibly of the fiber itself. To accomplish this goal, we will focus work tasks on the following technical objectives: • Evaluate available high strength fiber options; • Optimize Lifting Body and Spindle Design for Maximum Fiber Length; • Optimize Fiber Winding Process, Automation, and Quality Assurance • Computer Modeling of Deployment and Winding Process Key to the proposed approach is the optimization of our fully- automated process for fabrication of low-attenuation, low deployment- drag optical fiber packs. Extensive testing on our easily reconfigurable developmental winder will allow us to explore multiple design options, and the resulting prototype winds will be verified through testing in both our water tank test stand and in open-water towed deployment.

Title:Uncertainty Estimation for Atmospheric Acoustic Propagation Prediction
Abstract:The propagation of acoustic signatures from vehicles, aircraft, boats and artillery can have a significant impact on military operations. Specifically combatants need to reliably detect enemy acoustic signatures while at the same time concealing their own. The physical propagation environment, including surface and atmospheric parameters, may drastically alter the range at which an emitting object may be detected. There are currently several models for predicting these acoustic propagation effects based on atmospheric profiles and/or ground topography. Unfortunately these models are sensitive to errors in environmental inputs. We propose a method for estimating the uncertainty (variance) of the acoustic propagation prediction given the uncertainty in the environmental inputs. Advantages to this new method are (1) it fits within current Parabolic Equation (PE) marching algorithms and does not require a second stand-alone code and (2) it is computationally efficient. This would allow our forces to simultaneously predict both the acoustic propagation and its uncertainty. The algorithm used to calculate the uncertainty may also be used to determine the sensitivity of the sound field to the various individual environmental parameters which could aid (1) in acoustic environmental parameter inversion and (2) in the intelligent allocation of meteorological measurement resources.

Title:Atmospheric Acoustic Propagation Prediction
Abstract:Acoustic signatures radiating to the ground enable the enemy to aurally detect, locate, and classify inbound U.S. tactical aircraft. Multi-Service and multi-agency requirements exist to study the problem and to develop countermeasures, yet no capability currently exists to adequately assess our vulnerability problem. To address these applications, a modular system of acoustical tools is proposed to integrate the physical factors controlling the reception of the acoustical signatures on the battlefield. First and foremost, this system will provide a prediction of the noise from a source to a receiver location. However, behind this simple concept several physical factors influence the received signal. These factors include source emission characteristics, atmospheric conditions, and receiver capabilities along with the integration of the individual uncertainties. The primary factors in these uncertainties are the atmospheric conditions since they generate the most variation in the received signal. Each of these factors has current and on-going development, which will be leveraged for the proposed system. However, the integration and interaction of the uncertainties is required for accurate determination of risk and identification of enemy movements.

Abstract:In this program, we will assess the technical feasibility and the risks of three novel approaches that will allow the division of the 30-88 MHz frequency band into a minimum of 30 channels with a minimum of 30 dB channel isolation (band center to band center). For each approach, we will conduct computer modeling and demonstrate that this multiplexer can theoretically be built. We will then develop a plan on how this multiplexer would be built to meet the performance and size requirements. Finally, we will explore the technologies to design any components identified as key challenging components. Successful completion of this effort will form a solid foundation for building and testing an engineering prototype in Phase II.

Title:Multiple Channel SINCGARS Multiplexer
Abstract:Design techniques for a low loss 30 channel multiplexer are proposed. The Navy has a requirement for such a multiplexer in the 30 - 88 MHz frequency band for use in eliminating interfering signals in the receiver passband. Design approaches including L-C filters and combline filters are considered. Use of L-C filters will not meet the loss requirements. Proposed is an assembly of 30 round rod combline filters which have sufficiently high Q to meet the loss requirements. Techniques to be investigated include use of cross-coupling to improve out-of-band rejection without increasing pass-band loss. Design techniques for multiplexing the filters are discussed and an approach recommended which will allow the performance requirements to be met.

Title:High-Capacity Primary Battery for Extreme Environments
Abstract:MaxPower¡¦s goal during the Phase I program is to design and demonstrate the capability of a primary Li|CFx battery assembly that is capable of delivering in excess of 12 hours operation at -40„aC in a battery architecture that weighs less than 0.7 pounds and fits a 14 in3 envelope. Successful battery performance will hinge upon MaxPower¡¦s expertise in manufacturing of thin electrodes and implementation into hermetically sealed hardware. The battery architecture includes implementation of SOC technology using commercially available Integrated Circuits with minimal power consumption and low cost impacts. The combined battery chemistry with SOC implementation will limit costs and overall product development time. The developed SOC circuitry will be able to project remaining capacity based on temperature and previous discharge rates. Additionally, the battery assembly will contain an imbedded LED display in the casing that will indicate to the user remaining battery capacity when initiated by push button. After demonstration of the feasibility of the selected chemistry and SOC implementation, MaxPower will use modeling techniques to project performances for Phase II prototype development and build.

Title:Solid Electrolytes with Wide Temperature Operating Range for LiCFx Batteries
Abstract:This SBIR Phase I project seeks to develop thermally stable high-energy LiCFx batteries to satisfy mission operational temperature requirements of the Joint Tactical Radio System (JTSR) Handheld Manpack. Operations require batteries with capacities of 12 Ah over the temperature range from ¡V40„aC to 55„aC and storage stability from ¡V51.1„aC to 71„aC in a volume of 14 in3 and weight of 0.7 pounds. High capacity LiCFx batteries can meet these requirements if low temperature performance can be addressed. In this project we will develop LiCFx batteries with a novel solid electrolyte material that will replace the electrolyte and separator with a material that is both thermally stable at high temperatures and has excellent low temperature conductivity, a combination of traits that has eluded other solid electrolytes to date. TDA¡¦s solid electrolyte is based on a self- assembled polymer that contains Li-ion channels with impressive ionic conductivity over a broad temperature range.

Title:Spectrum Planning and Management Capability for Radio Communications
Abstract:Leveraging game theoretic principles developed on an ONR basic research grant by the prime investigator at Virginia Tech, CRT has developed a suite of low-complexity joint spectrum monitoring and management algorithms intended for deployment as embedded processes in stationary nodes in ad-hoc networks which solve for optimal spectral reuse patterns in a policy constrained dynamic spectrum access (DSA) environment. Previous CRT studies showed that these algorithms can reduce interference by 30 dB and increase capacity 16 times. Because of the embodied game theoretic principles, these embedded processes operate independently yet ensure rapid network convergence and stability and resource allocations which minimize interference. By eliminating the need to coordinate actions or distribute operational information, these networks rapidly respond to changing conditions and the entry and exit of nodes and eliminate catastrophic failures induced by losses of critical nodes. This project refines these algorithms for use in military networks by adding mobility support and techniques to mitigate the presence of hostile users. To reduce the time to field these results, Phase I undertakes a detailed study of how to integrate the algorithms into the SCA and Phase II implements a prototype system on military radios running the WNW waveform.

Title:Spectrum Planning and Management Capability for Radio Communications
Abstract:The project’s objective is to develop a spectrum planning module that autonomously provides spectrum assignments to a JTRS radio MANET- based network. The key technical objective is to determine what the spectrum assignment rule sets used for the dynamic frequency assignment. Presently this is done manually based on a combination of networking management software to achieve network topology goals and with spectrum management software to minimize interference between different systems. In this project we automate this process using local and distributed measurements and the already developed automatic MANET topology, routing system and link layer software. We show how the spectrum planning module can easily be integrated with the existing and planned JTRS software. We develop open APIs between the spectrum planning module and the existing JTRS modules within the SCA. We make networking overhead, memory size and CPU estimates so that we can determine what spectrum planning module will fit within the JTRS transceiver system.

Title:Active Conceptual Modeling Technology Supporting Joint C4ISR
Abstract:This project proposes to study the core concepts of Active Conceptual modeling (A-CM) with applications to military and commercial systems. We plan to explore the feasibility of extending the mathematical framework for Entity-Relationship (ER)-based active conceptual modeling developed by Dr. Peter Chen to represent scenario snapshots that include time, space, uncertainty, and perspective dimensions. the mathematical framework will be based on set theory, Modern algebra, and other branches of mathematics. We also plan to explore mechanisms for the computation and representation of differences between snapshots for model evolution. In Phase I, we will evaluate the feasibility of developing information services derived from active conceptual modeling. We plan to identify a set of information services that will be benefited by the A-CM technology. We also plan to design and implement a simple version of one or more such information service tools to test the feasibility and validity of the mathematical framework and the representation and computation of the conceptual model difference mechanism.

Title:Semantics and Tools for Active Modeling and Processing in the Enterprise Data Environment (STAMPEDE)
Abstract:Databases are proven shared repositories for the enterprise, and conceptual modeling is solidly established as a valuable step in defining the contents of those databases. However, database contents, and the models that define them, are generally static, snapshot-oriented views of the world. While this may once have been the only feasible approach, advancing technology is relaxing memory hierarchy constraints, and now allows on-line integrated access to historical, hypothetical, and/or multi-perspective data. A well-defined and supported data model (e.g. with strong semantics, visualizations, editors and query tools) that explicitly encompassed change over time, space, perspective, and states-of-knowledge would enable more rapid development of new classes of applications. We propose to develop Semantics and Tools for Active Modeling and Processing in the Enterprise Data Environment (STAMPEDE). Our approach relies on an innovative combination of ideas and techniques from Aspect Oriented Programming, Meta Object Formalisms, and Generative Model Transformations. During Phase I we will flesh out the ideas underlying this approach and demonstrate their applicability in detail to a single active modeling aspect, including reflecting that aspect into the metamodel to enable active schema modeling. We will produce analysis and limited proof-of-concept tools, and develop a detailed Phase II design and work plan.

Title:High-Z Polymer Composites as a New Category of Gamma Scintillator Materials
Abstract:We propose a radically new approach to gamma scintillator materials based on high-Z polymer composites. These composites contain two key components molecularly dissolved in a polymer matrix that serves as the binder: (1) high-Z compounds for stopping high-energy gamma radiation; (2) luminescent conjugated polymers that functions as the scintillation activator. The molecular-level dissolution ensures high optical clarity. The polymeric matrix occupies a low volume fraction of the composites such that the effective Z is predominantly determined by the high-Z compounds. The high-Z compounds absorb incident gamma radiation. The deposited energy is transferred to the polymer and is released as visible photons. The proposed research involves liquid composite formulation and photophysical studies of the gamma attenuation, energy transfer, and light emission of the composites.

Title:Characterization and Mitigation of Radiation Effects in High-Speed Compound Semiconductor Microelectronics
Abstract:For ultra high speed applications in DoD satellite systems, devices and circuits fabricated from III–V semiconductor compounds offer significant advantages over silicon-based technology in terms of operating speed and power. However, the uncertainty in single- event-effect (SEE) response of compound technologies forces the use of empirically- based hardening techniques with penalties in increased power, area, and weight. To enable better characterization and mitigation of SEEs in III-V technologies, CFDRC, in collaboration with Northrop Grumman Corporation (NGC) and Naval Research Laboratory (NRL), proposes the following innovations: (a) Accurate and cost-effective modeling of radiation effects in advanced high-speed III-V devices and circuits, enabled by enhancements to CFDRC’s NanoTCAD 3D/mixed-mode simulator; (b) New, more precise, charge generation models to complement the latest laser-based experimental techniques; (c) Simulation-supported design and validation of minimally-invasive mitigation techniques for SEEs. In Phase I, a representative advanced compound MMIC (Monolithic Microwave Integrated Circuit) will be used for ‘proof-of-concept’ characterization of SEEs (single- event upset/transient) by means of 3D/mixed-mode simulations, validated on a relevant high-speed mixed-signal circuit from NGC. Plans for SEE mitigation methods will be developed. In Phase II, the simulation efficiency will be significantly improved by adaptive 3D meshing, parallelization algorithms, and distributed mixed-mode computing. SEE mitigation methods for III-V ICs will be numerically explored, verified, and demonstrated.

Title:Engineered Substrates for “Zero-Penalty” Radiation Hardening of Ultra Deep Submicron Commercial Processes
Abstract:We have developed engineered epitaxial layers based on nanostructure technology that can potentially harden commercial silicon devices against radiation by minimizing collected photocurrents (electron-hole pairs) via recombination centers. Adding recombination centers in CMOS devices is a well-known technique for reducing the collected charge; however, attempts at manufacturing a device with this property has lead to unsatisfactory levels of leakage current. Because of these leakage currents, efforts at hardening devices without special processing or design changes have been focused on buried regions, such as buried guard-rings. While buried regions can improve single event response by truncating funneling, electron-hole pair yield is largely unaffected in the active and silicon/silicon dioxide regions. During the Phase I portion of this effort, we will demonstrate the enhanced recombination benefits of such engineered material, using wafers provided by Texas Instruments (TI) at no cost to the program. During a Phase II program, we will optimize the nanostructure film for use in various TI fabrication facilities. Radiation Assured Devices in Colorado Springs, CO will perform all the radiation exposures and electrical testing.

Title:Portable Time of Flight Mass Spectrometer for Nuclear Forensics
Abstract:Analysis of nuclear material samples in the field has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of a truly portable mass spectrometer for nuclear forensics. Our device will feature greatly reduced size and improved portability over commercially available units by combining proven, miniaturized mass spectrometer, vacuum system, and laser ablation ionization technologies. These technologies will be combined with an easy-to-use package and interface that will enable soldiers-in-the-field to perform analyses in less than a day that today require days to complete due to the need to ship samples from the field to DoE laboratories. The Creare team is extremely well qualified to develop and transition/commercialize this technology. The team is currently collaborating on the development and fielding of a mass spectrometer and vacuum system that will be used to perform in situ mass spectrometry on Mars as part of the 2009 NASA Mars Science Laboratory mission.

Title: Advanced nanocomposite scintillator for gamma radiation detection
Abstract:Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the nanocomposite are superior to those of available single crystal scintillators, offering 10 to 20 times higher detection efficiency, improved energy resolution, and response times of a few nanoseconds. The proposed nanocomposite intrinsically eliminates light scattering by big nanocrystals, yielding excellent transparency for large volumes, and is scalable, low-cost, and robust in harsh environments. Phase I demonstrates the feasibility of the approach; Phase II will demonstrate a complete scintinallator instrument.

Title:Bulk Composite Materials for Detection of Gamma Radiation
Abstract:The objective of this proposal is to develop enabling technology for the production of bulk scintillating nanocomposites that have gamma radiation detection properties of single crystal NaI but with the manufacturability of plastic scintillators. These performance criteria may be met by developing nanoparticle polymer composites with ultra-high nanoparticle loadings. These ‘ultra-composites’ would contain the minimum quantity of organic binder necessary to retain suitable mechanical and optical properties. In addition, the development and incorporation of polymers composed of high Z atoms will increase the stopping power of these materials. This increased stopping power from the polymer matrix will allow for more flexibility in the required nanoparticle loading level to obtain sufficient nanocomposite stopping power. While the specific scintillation materials used in this program are CdSe and CeF3, it should be stressed that this technology is applicable to all types of nanoparticles for scintillation.

Title:Engineering Models for Damage to Structural Components Subjected to Internal Blast Loading
Abstract:The team of Protection Engineering Consultants (PEC) and Applied Research Associates (ARA) will develop a fast-running methodology that predicts damage levels of structural members subject to the blast environment from high explosives detonated inside a building (i.e., internal explosions). The research in Phase I will focus on reinforced concrete slab components. The methodology will consist of a combination of pressure-impulse (P-i) diagrams, scaled structural response curves for internal blast loads from TM 5-1300, a single-degree-of-freedom (SDOF) model, and design charts for localized response. Criteria will be included to select the fast-running methodology that is most applicable and efficient for each component depending on several factors including the blast load characteristics. Although each of these methods exists in a current form, significant work will be performed to modify them as necessary so that they are more applicable for efficiently analyzing components subject to internal blast loads. Also, significant work will be performed to understand internal blast loads using data and calculated values. The methodology will be validated utilizing existing test data and synthetic data generated by high fidelity computational codes. It will also demonstrate implementation of the methodology into VAPO.

Title:Engineering Models for Damage to Structural Components Subjected to Internal Blast Loading
Abstract:Predicting the response of building components to internal detonations is more complex than the corresponding task for external loads because of the more complex loading waveforms which include multiple reflections in the shock phase followed by a long duration pseudostatic loading that depends upon room venting. Add the possibility of additional impulsive loading from primary debris. We propose to generate a fast running model capable of predicting damage from internal detonations incurred by a wide variety structural components, materials and construction methods, e.g., steel stud walls, reinforced concrete, concrete masonry units, etc. Step one involves categorizing and simplifying the variety of possible loading wave forms and parametrizing them for use as loading functions in the detonation room as well as adjacent rooms. We propose to use the MAZ computational fluid dynamics code and available experimental data to categorize the appropriate waveforms and then reduce them to simplified loading functions that produce the equivalent structural responses. We will use the FLEX computational structural dynamics code plus existing test data to generate a damage data base that will be incorporated into a fast running damage response model. The model will be validated against first principles computations and existing and new test data.

Title:Agent Defeat using a DWA Accelerator
Abstract:A new type of compact induction accelerator currently under development at the Lawrence Livermore National Laboratory (LLNL) promises to increase the average accelerating gradient by at least an order of magnitude over that of existing induction machines. The machine is based on the use of high gradient vacuum insulators and advanced dielectric materials and switches. The system, called the Dielectric Wall Accelerator (DWA), employs a variety of advanced technologies to achieve a very high gradient. The high gradient capability of this design implies reduced size and cost for the same energy as larger accelerator systems. Reduced size also makes possible improved system mobility, which makes this an interesting new accelerator based high energy radiation source for National Defense and Homeland Security applications. This research project will determine the effectiveness of protons accelerated in this structure with energies from ~ 5 MeV up to 250 MeV can be used to defeat bio-agents and other WMD. The information will be used to determine the optimum configuration of compact mobile DWA for defeat of WMD. The information will be used to design a prototype DWA system in the Phase II research.

Title:Sequential Isoelectric Point Separation of Proteins Using Non-Gel, Microfluidic System
Abstract:The measurement of biochemical changes within the human body can provide a means to monitor a person’s physiological health. Many of the biochemicals that provide a snapshot of a person’s health are proteins. The challenge with measuring proteins is the existence of approximately ten orders of magnitude difference in concentration between the most abundant proteins in blood and those typically used to determine disease and physiological state. This proposed effort aims to develop a modular mass spectrometer for proteome profiling of readily available biological fluids comprising of user-configurable components for applications ranging from field-deployable pathogenic detection to customizable assays for biomedical diagnostics. The specific innovation is in the fabrication and integration of discrete microscale subsystems, including microfluidic chips for sample processing and miniature mass analyzers for spectroscopic analysis. The small form factor of all components enables the manufacture of compact mass spectrometers that will eventually reside in domestic to far-forward military medical facilities, clinics, doctor’s offices, or even nearby the patient in the hospital setting. The compact form factor will also enable the development of systems for far-forward deployment capable of on-site detection and monitoring of biological warfare agents / toxins.

The combination promises to establish a new standard for identifying low concentrations of chemicals using a compact, easy-to-use system. At the end of a successful Phase II, we would deliver a prototype unit having a footprint similar to the FirstDefender that is capable of identifying chemicals within seconds, and ready to be put into use very quickly. In Phase I of this program, we plan to build a breadboard version of the system that employs a 980 nm laser, a probe, a miniature spectrometer, and an InGaAs array.

Abstract:The overall goal of this proposed program (through Phase III) is to build a hand-held Raman analyzer that can perform non-contact identification of chemicals in the field. This will be accomplished by modifying a commercially available FT-Raman analyzer to employ 976 or 1064 nm laser excitation. Feasibility will be demonstrated in Phase I by comparing the ability of three Raman systems using laser excitation at 785, 976, and 1064 nm to measure some 50 chemicals in terms of fluorescence and thermal emission minimization, and identification of unknowns using spectral matching algorithms. During Phase II an ~ 10 pound hand-held Raman analyzer will be designed and built that includes a comprehensive spectral library of actual chemical warfare agents, explosives, and toxic industrial chemicals; and employs a Personnel Digital Assistant for analyzer control that includes spectral acquisition and spectral matching with statistics to allow chemical identification in real-time (< 5 minutes). The analyzer will employ a simple to operate user- interface, and will be delivered at the end of the program.

Title:Collective Protection for Military Working Dogs
Abstract:Shelter enclosures for military working dogs in the event of a CB attack is a technology gap identified by the Joint Requirements Office. Important parameters to consider in the design of protective enclosures include low weight and size to minimize transport requirements; rapid setup; and accommodation of canine physiological and psychological comfort needs. The overall operational weight of the enclosure would also be a function of its power requirements which in turn is a function of its operating mode. Therefore, Agave BioSystems, in collaboration with Gentex Corporation and Dr. Joseph Wakshlag of the Cornell College of Veterinary Medicine, proposes to design and develop protective enclosures for military working dogs that meet these parameters. In the Phase I, this team will define the canine physiological and psychological parameters of importance to enclosure design; develop multiple designs to allow consideration for both powered and non-powered enclosures as well as active and passive materials; and demonstrate proof of concept for the protective capacity and long-term kenneling suitability of the designs.

Title:Collective Protection for Military Working Dogs
Abstract:Doctrine for employment of canines in a CBRN environment has evolved into a Collective Protection approach. Providing COLPRO has several very significant implications for Canine kennels and shelters: „X The outer surface of the structure must be CB agent impervious „X The outer surface of the structure must resist effects of the decontamination process „X The system must provide the animal a supply of filtered air and provide for the discharge of exhaled air „X The system must manage the thermal environment and additional loading generated by the encapsulated canine Because of the potential for an extended dwell time within the COLPRO structure we have to add another set of requirements to the system ¡V management of the ¡¥hotel¡¦ functions: „X ¡¥atmospheric¡¦ humidity within the structure „X the animal¡¦s bodily waste „X noise from air supply and thermal management devices, etc. „X light levels within and visibility from outside the structure „X access to the animal by the handler We must also apply the limitations of low/no power requirements, low bulk for shipping and having a system which has broad or ideally universal applicability ¡V not just as a COLPRO device. Development of such a shelter is the subject of this proposal.

Title:Dynamic Multicomponent Optical Analyzer for Chemical Weapon (CW) Exposure Studies
Abstract:In this SBIR Phase I effort, Los Gatos Research (LGR) proposes to design, develop and test a novel laser-based gas analyzer optimized for chemical weapon exposure studies based on cavity enhanced absorption in the mid-infrared spectral region. This analyzer will provide sensitive and accurate quantification of several chemical weapons through real-time measurements of high-resolution absorption spectra recorded in the mid- infrared. The instrument will employ Off-Axis ICOS, an extraordinarily rugged and commercially-proven cavity enhanced laser absorption technique that uses an optical cavity as absorption cell for significantly improved sensitivity, and mid-infrared lasers for high specificity and low false positives. The SBIR instrument will be the first system capable of providing rapid quantification of chemical agents and enable improved understanding of the dose-response characteristics of the subject in real time.

Title:Dynamic Multicomponent Optical Analyzer for Chemical Weapon (CW) Exposure Studies
Abstract:We propose to build a compact laser photoacoustic spectrometric (LPAS) sensor for continuous, real-time broadband analysis of multiple chemical components, and perform field tests to qualify it for dynamic monitoring of chemical warfare agents (CWA). Our sensor will be based on our laboratory LPAS instrument (at technology readiness level TRL-4) that has already demonstrated successful multicomponent chemical detection with CWA1, toxic chemicals and explosives2. It utilizes a tunable infrared laser (CO2 or quantum cascade), a high sensitivity photoacoustic cell with an air sampler and an efficient algorithm to rapidly complete high sensitivity, selective multicomponent measurements in under a minute. In Phase I we will carry out extensive laboratory and preliminary field site tests of LPAS with simuants, and a comprehensive analysis of the sensor performance using a model to determine the LOD and ROC curves for the sensor and establish its feasibility. A rugged and portable prototype sensor (TRL-5) will be built in Phase II. It will be field tested with actual toxic agents in DoD test sites to qualify (TRL-6) and characterize the sensor.

Title:Dynamic Multicomponent Optical Analyzer for Chemical Weapon (CW) Exposure Studies
Abstract:Spectral Sciences Inc. proposes to develop a prototype sensor for real-time trace-level analysis of complex multicomponent gas mixtures, specifically those containing Chemical Weapon (CW) agents and interferents. The instrument is based on high power quantum cascade lasers and photocoustic spectroscopy detection. Advanced detection algorithms take advantage of wide spectral coverage to provide high sensitivity with low occurrence of false positives. The laser source features digitally controlled fast wavelength tuning and wavelength modulation. An integrated-optics acoustic transducer provides noise-cancelling gas absorption signal acquisition. In Phase I and Phase I Option tasks, the digitally tunable and lockable laser source will be demonstrated, followed by the delivery of a laboratory prototype by the end of Phase II.

Title:Multiple Indication Adjuvants
Abstract:The objective of this study is to demonstrate the efficacy and broad applicability of the human immune-modulating alphaGal Adjuvant Technology for antiviral vaccine development. We will use viral vaccine candidates for the select Category A viral pathogens Zaire ebolavirus (ZEBOV, filovirus), Rift Valley fever virus (RVFV, bunyavirus), and Lassa virus (LV, arenavirus), to evaluate the adjuvant potency of the alphaGal Adjuvant Technology. This technology is based on the innate naturally acquired human immune response to galactose alpha(1,3)galactose alpha(1,4)N-acetylglucosamine (alphaGal) epitopes. In Phase I we will illustrate the broad application of the alphaGal Adjuvant Technology to antiviral vaccines by demonstrating that alphaGal-modification significantly enhances and modulates the immune response to select vaccines in a mouse model. In the Phase I Option, the optimized adjuvant conditions eliciting the best immune response to the different tested antiviral vaccines, based upon the mouse model immunological data, will be utilized in limited lethal challenge efficacy experiments to be conducted with wild-type virus under Biosafety Level (BSL)-4 conditions in the mouse model. Significant efficacy will lead to a Phase II proposal and further studies involving adjuvant efficacy in small rodents and non-human primates.

Title:Camouflaged liposome construct for efficient drug delivery across the blood-brain barrier
Abstract:A major obstacle to non-invasive treatment of brain injury and disease is the blood-brain barrier (BBB), which prevents many intravenously injected therapeutics from being taken into the brain. In this program, Luna Innovations and Virginia Tech propose to develop a novel liposome-based delivery system capable of delivering any of a variety of neuroprotective agents of use against organophosphate-based nerve agents. This novel system combines a recently developed “Trojan horse” peptide capable of ferrying the construct across the BBB with liposome technology previously developed at Luna that can be adapted to achieve drug delivery over a specified time frame. The proposed system also has neural specificity, targeting the tissues that are most affected by nerve agents. During Phase I, the Luna team will synthesize and assemble the system components, demonstrate encapsulation of assorted neuroprotective agents, and perform preliminary in vivo and in vitro testing of system efficacy.

Title:Blood Brain Barrier (BBB) Permeable Encapsulating Agents for Effective Delivery of CNS-active Agents
Abstract:Drug transport in the central nervous system is highly regulated by the Blood-Brain Barrier (BBB). Most medicines, including many for treating cancer, Alzheimer’s, and stroke, do not meet essential criteria, such as lipophilicity and low molecular weight, required for appreciable transport into the brain. However, endogenous peptides, such as insulin or transferrin, and certain monoclonal antibodies, undergo receptor-mediated transport (RMT) across the BBB in vivo after binding to specific receptors or transporters localized within brain capillary endothelial cells (BCEC). Brain-delivery of brain-impermeable therapeutics can be accomplished by attaching them as payloads to these macromolecules. BBB transport of large molecule pharmaceutical payloads – including recombinant proteins, other antibodies, RNA interference drugs, and non-viral gene medicines – has been mediated in this fashion. Novel liposomal and polymer encapsulation methods have made it more facile to transport a large number of such molecules, attached as a single payload to a receptor-targeting mAb, across the BBB. In Phase I of this project, Lynntech, in collaboration with Dr. Abbott at Texas A&M Univ., will evaluate a suite of novel platforms for payload encapsulation and demonstrate their effective receptor-mediated transport and delivery in the brain.

Title:Oligonucleotide Enzyme Surrogate (OnES)
Abstract:Historically organophosphorus compounds such as insecticides and nerve agents have been susceptible to decomposition by proteinaceous enzymes. Organophosphate hydrolases (OPH) represent a practical method to deactivate such compounds peripherally and on surfaces. However, when such organophosphates are ingested, the use of proteinaceous enzymes such as OPH can be problematic because of their tendency to produce an immune response. In order to avoid this issue, Accacia International will manipulate DNA oligonucleotides using a novel and innovative selection method. DNA aptamers will be selected through the Systematic Evolution of Ligands by EXponential enrichment (SELEX) method to accomplish the task of creating an enzyme surrogate.

Title:Ribozymes for In Vivo Degradation of G-Nerve Agents
Abstract:Given the possibility to administer prophylactic doses of protein bioscavengers inactivating OP nerve agents before they reach their acetylcholinesterase target, much attention has been given to proteins such as human butyrylcholinesterase and paraoxonase I. As small nucleic acid catalysts can exhibit triphosphoesterase activities, the identification of new molecules active against nerve agents would constitute a significant breakthrough for the development of a biopharmaceutical approach against OP agents, with rapid optimization of catalytic rate, stability, large-scale production, storage and formulation. In this Phase I, Agave BioSystems proposes to develop novel catalytically active oligonucleotides against G-nerve agents using high throughput selection in E. coli. The development of a high-throughput selection method in E. coli to identify novel RNA molecules able to hydrolyze nerve agents constitutes a promising and innovative approach. Unlike other methods typically used for the de novo creation of new RNA or DNA catalysts, this in vivo approach will directly identify molecules combining favorable binding and dissociation constants, as well as strong catalytic activity.

Title:Human Social, and Culture Behavioral Modeling Game-Based Simulation
Abstract:We propose the design, creation, and delivery of the Advanced Group Interaction Simulator (AGIS), a simulation platform and application with particular focus on sophisticated crowd dynamics, game-like storyboarding and play, and complete accessibility for the scenario creator. Users will be able to create their own behavior and control algorithms from a spectrum of basic and more complex group dynamic and crowd behaviors directly through the user interface (no programming). Users will also be able to create their own behavior and control algorithms by adding and extending those building blocks via PERL scripting at runtime (no compile required). In addition, users will be able to create their own group interaction plug-in modules (C++ .dll libraries) to the application from a well-documented API interface, allowing them to once again modify and extend the behaviors, or even create their own new ones from scratch. AGIS will start by using DI-Guy AI Scenario as core software and then dramatically build and extend upon it. This allows AGIS to leverage the ongoing advances, 500+ characters, 2000+ motions, and the well-tested, broad and deep SDK API of this industry leading COTS software. AGIS will have strong commercial potential and strong marketing backing as part of our Human Simulation product line.

Title:Human Social, and Culture Behavioral Modeling Game-Based Simulation
Abstract:We do not offer a perfect simulation of social behavior. Instead we offer a digital sandtable where users can experiment with new ideas. Radically different interfaces meet the needs of radically different users. The system can be engaged at any of four levels, At the outermost level, it is a videogame. The player accepts mission instructions and confronts the challenges. His skill and ingenuity are matched against his opponents, human or synthetic. The layer below belongs to the Scenario Designer. Using a special editor, he establishes the Player’s missions, sets up obstacles, adversaries and allies. At the third level inward are the simulation formulae. Modeling experts and subject matter experts have access to these and can change parameters and proportions to revise the behavior of the synthesized populations. At the core lies the simulation logic itself. It inevitably embodies certain assumed principles. Fortunately, the logic can be unplugged and replaced with a completely different AI engine. A change to the behavior logic, to the simulation parameters or to the current scenario will affect the player’s experience and the game outcome. But the integrity of game itself – its mechanisms of display and interface and network play will remain unaltered.

Abstract:Game-based simulation is rapidly becoming the preferred strategy for training military planners in handling a variety of missions including insurgencies, small wars, and/or emergent conflicts. What game-based training simulations lack today is: the need for socio-cultural sensitivity in training scenarios; low cost, versatile platform capable of supporting both single and multiplayer interaction via a PC, network, or Internet. Phase I of this effort is concerned with developing the system concept and technical architecture of a game-based simulation that combines scenario scripting/editing, storytelling, and pedagogically-driven user feedback/performance assessment in a low cost, small footprint package.

Title:Dynamic, Agent-Based, Societal Model for Factional Adversarial Games
Abstract:Physical Sciences Inc., proposes to develop a novel, dynamic, agent-based, societal model for studying coalition formation and factional competition. Our unique approach uses a detailed representation of human behaviors and environmental elements pertaining to coalition formation, strategic decision-making and factional competition/cooperation: geography, culture, religion, language, individual and collective emotions, history, and resource availability and needs. The proposed model consists of: (1) a global environment (World) and subsequent geographical regions: Spaces, Sites, Districts, and Villages, which are hierarchically arranged; (2) individual Villages that consist of tribes and resources; and (3) human agents endowed with individual and collective learning and decision-making capabilities. Phase I will: (i) develop the proposed societal model; (ii) develop a Java agent-based software simulation tool for the model, using Ethos as societal description and representation framework and RePast as simulation platform; (iii) Develop rule-based and game-tree search factional decision-making algorithms for controlling the brains of the modeled agents; and (iv) simulate a scenario of factional adversarial game based on the Afghan tribal structure and demonstrate both qualitative and quantitative prediction capacities of the proposed model.

Title:AI Middleware for Human Social-Cultural Behavior Training Games
Abstract:For effective training in higher-level decision-making and social-interaction skills, there is a need for computer game technology to provide more realistically human-like non-player characters. As a cost-effective path for integrating greater social-cultural realism into game simulations, we propose a set of AI (Artificial Intelligence) Middleware layers that allow easy extensibility and configuration at a variety of levels of abstraction in game designs. We plan to determine an appropriate game concept and engine, create AI Middleware that is particularly geared toward social-cultural human behavior, and develop an example game instantiation of the design. The implemented game engine will have a relatively open architecture, and plug-in application programmer interfaces (APIs) that provide control of non-player characters (NPCs) in standard ways as well as in ways specific for the modeling of social-cultural human behavior. The system will support alternative human behavior architectures, and provide scripting and behavior-modeling interfaces to allow rapid development of simple and/or well-understood behavior models, but also provide an appropriate migration path for developers (and possibly end users) to improve the models in the areas where more sophistication is desirable.

Title:Second Language Training
Abstract:Language retention is a significant and growing issue for the US military (and US businesses) as Soldiers face increasing overseas deployments and heightened level of interactions with local populations. The success of these one-on-one interactions set the stage for the success of the overall mission. However, languages knowledge (particularly for languages learned after childhood) deteriorates quickly with non-use and, unfortunately, the first skills lost are usually the more important ones -- the mission- specific language knowledge learned last. KUMA GAMES is a world-renowned consumer video game developer, with tens of millions of downloads around the world of our unique “episodic game” experience. Additionally, we are an experienced simulation developer with multiple training projects for USA CASCOM-TD. Our unique capabilities include world- class game development, linguistic training expertise, TV-quality video production, proprietary internet-based scenario delivery, and access to key 3rd party technologies including voice recognition and advanced graphics tools. Utilizing our tools, experience, and huge library of existing 3D assets we can provide an effective, cost-efficient, rapidly-deployable and easily updatable language retention toolset for trainers and Soldiers deployed around the world. It is our intention to refresh languages skills in an intense and immersive 3D environment, which would be made available as part of an online/offline language exercise portal utilizing the follow five key capabilities. Soldiers would: - participate in machine-guided evaluative exercises - work with expert language trainers via network-based video game “multiplay”, repurposed here for remote learning - participate in iterative exercises conducted by culture-specific virtual characters and a world-class voice recognition technology to refresh and tune vocabulary and pronunciation - exercise their knowledge in intense, voice-enabled first-person scenarios customized for their language skill level and mission-specific communication needs - participate in a global "social" network of Soldiers and trainers -- utilizing KUMA's advanced communications tools -- for ongoing language and cultural guidance.

Title:Second Language Retention Intelligent Training System
Abstract:Military personnel who take part in intense periods of second language (L2) training are at risk of losing their second language skills during periods of underutilization. This proposal describes a research effort aimed at addressing this problem through the creation of the Second Language Retention Intelligent Training System (SLR-ITS). Our solution consists of three main elements. The first is developing an initial theoretical model of L2 retention and a research design to test this model. The second element is translating the theoretical model into pedagogical materials and a training methodology. The final element is developing a prototype of the SLR-ITS that makes use of this translation in both a scenario-based training environment and in a training environment aimed at portable devices (e.g. iPod). This work draws on the experiences of Stottler Henke in creating intelligent training systems and on the experiences of our consultants, Dr. Bardovi-Harlig and Dr. Stringer, in second language acquisition. The expected benefits of this research program are an increase in the effectiveness of L2 training and a decrease in the need for L2 retraining.

Title:Second Language Sustainment Training with the Tactical Language and Culture Training System
Abstract:In this project we will develop a language training module concept that addresses the problem of language attrition. The concept addresses the multiple aspects of this problem: durable language acquisition that is resistant to attrition, diagnosis of language attrition when it occurs, and skill maintenance training focused on the skills that trainees are in the process of losing. The design of the training concept will draw on research in the psychology of language attrition, while building upon best emerging technologies and methods for language training. The concepts will extend the Tactical Language and Culture Training family of training systems, including Tactical Iraqi and Tactical French, resulting in practical training solutions that transition into Navy and Marine Corps use, yielding concrete training benefits to Sailors, Marines, and language learners generally. We will conduct follow-on evaluations of the effectiveness of the approach in helping Sailors and Marines to retain their language skills.

Title:Rapid Ethnographic Assessment Program
Abstract:This project proposes to develop a rapid ethnographic assessment tool designed specifically to be used by military personnel participating in Security, Stabilization, Transition, and Reconstruction (SSTR) missions who are untrained in social science research methods. Within the Department of the Navy, potential users include Naval Special Warfare, Marine Special Operations Command (MARSOC), and the Maritime Civil Affairs Group (MCAG) within Naval Expeditionary Combat Command (NECC). Each of these force elements is uniquely positioned to collect ethnographic data prior to large- scale military operations. Because potential or acute political instability is a precursor to United States military involvement in foreign countries, the proposed methodology is informed by both anthropology and political science, the former providing a local level perspective and the latter providing a ‘top-down’ approach assessing group relationships with central government(s) and structural/institutional drivers of stability. The interdisciplinary methodology is differentiated from the US Army Human Terrain System (HTS) because it provides Naval forces the capability to conduct assessments using organic assets, and will support broad elements of the SSTR mission set, to include the Department of State’s Coordinator for Reconstruction and Stabilization (S/CRS) Post- conflict Reconstruction Essential Tasks. This methodology will be tested in the Gulf of Guinea.

Title:Rapid Ethnographic Assessment Program
Abstract:As the Department of Defense continues to emphasize the importance of more effective stabilization and reconstruction operations, the need is clear for decision support tools that can help troops working day-to-day in different cultures. The objective of this Phase I SBIR is to provide OSD and Human Terrain Team analysts with additional insight into the potential cultural effects of different military missions. An ethnographic data collection plan will be developed and automated to synthesize data from multiple sources. Innovative algorithms will be developed to provide military planners insight into potential cultural risks as a result of military missions. The resulting Ethnographic Planning Tool will be capable of comparing task options to minimize potential risks and impacts to host-country cultural elements. The data fusion framework integrating the ethnographic data sources will be built on an infrastructure initiated by investments from the Missile Defense and Navy offices to provide a robust decision trade-space during acquisition decisions. The Phase I program will solidify the Phase II requirements by having selected OSD analysts interact with the proof-of-concept graphical user interface and database structure to conduct ethnographic-based mission planning. The Phase II program will develop a prototype tool and validate its operation and use concept.

Abstract:Applied Visions, Inc.

AVIsor will build upon our work on a similar SBIR project sponsored by the Navy for the Tactical Tomahawk Weapon program. The result of that effort, the Tactical Target Analysis and Prediction System (TTAPS), uses computer gaming technology, including agent-based artificial intelligence algorithms, to predict the likely destinations and paths of targets vehicles. For this project we will adapt that technology to efficiently generate and visualize safe convoy paths based on multiple regional factors including civilian reaction, local infrastructure, traffic and their effects on the choice of best paths though the road network.

Title:Culturally Aware Routing and Risk Management Application (CARRMA)
Abstract:Attacks against land-based convoys have become one of the defining characteristics of Operation Iraqi Freedom, with ambushes by snipers and improvised explosive devices (IEDs) accounting for an enormous proportion of U.S. casualties. The vulnerability of convoys has been exacerbated by several factors. For one, there is the nonlinear nature of the battlespace in Iraq: Unlike conflicts between conventional forces, there is no rear area in which supply operations are relatively safe from attack. Indeed, even among individual Iraqi citizens, feelings about the presence of coalition forces are mixed and subject to change as political and economic conditions shift. Thus, a given neighborhood or tribe might be considered as predominantly pro-American at one time, but subsequently viewed as less tolerant of the presence of coalition forces. To complement phase-in of the MRAP, we believe it is technically feasible to design a system designed to reduce the likelihood of ambush in the first place. One capability of this system will be to plan and adaptively manage convoy routes.

Title:ARCORP - an Adaptive Risk-based Convoy Route Planning decision tool
Abstract:This proposal describes ARCORP, an Adaptive Risk-based Convoy Route Planning decision tool that extends our Course of Action (COA) development framework and Risk- based Route Planning (RBRP) application prototype. RBRP is a Web application that enables users to plan missions, minimizing risks of attack. Using past incident data derived from SIGACT and MTF reports, the route planning application learns the risk associated with various features and fuses this knowledge with geospatial knowledge layers into the route planning process. In this effort, we will pursue two areas of significant new research that is not addressed on our RBRP project. First, we will develop trafficability models, algorithms, and a decision tool that analyzes a fused social, cultural, geospatial, and event knowledgebase. For example, ARCORP will apply knowledge from past experience learned from historical patterns of dismounted and motorized traffic to predict trouble spots associated with scheduled events such as outdoor bazaars, religious services, job recruitment queues, and other events. Second, we will develop adaptive learning mechanisms to represent dynamic events such as traffic conditions, route conditions, and attacks in our models. To support these capabilities, we will also perform research in geospatial and socio-cultural data sources, collection methods, and knowledge engineering.

Title:An Advanced Risk-Based Route Planning System
Abstract:Typical route planning systems only take a few factors into account when planning an optimal path, namely the overall length of the path and the type of road in order to find the shortest traversal time. This proposal intends to augment existing known path and route planning algorithms - taking additional factors into account when planning a path. The concept of the “shortest traversal time” will be augmented by assigning environmental ‘risk factors’ to different segments of the candidate path. These factors include descriptors such as hostility to foreign presence, time of day, sensitive areas or buildings, or areas with known risks for snipers or IED attacks. The logistics planner or operator can use this software to find the shortest paths with an acceptable risk factor. The advanced path planning software will be able to find the optimal path and it can provide a series of alternative paths. Operators can also specify a known path and have the algorithm calculate the risk level. The advanced path planning software will be able to identify why a particular path was assigned a particular level of risk, what the different risk factors are, and why the path was recommended or rejected.

Title:Three Dimensional planning of safe routes
Abstract:Unique challenges exist for U.S. and allied forces within post-conflict areas controlled by hostile forces. Route planning through an area where the customs, lifestyles and social norms are not thoroughly understood presents one of the challenges for these forces. The proposed solution utilizes a three dimensional search technique in (x,y,t) complemented by a probabilistic three dimensional representation of hazards. These hazards depend on the cultural mores as well as the level of aggressiveness. We have assembled a strong team with Robotic Research, General Dynamics and Rababy and Associates that has extensive experience developing, testing and deploying planning solutions.

Title:Dynamic Modeling of Safe Routes
Abstract:The timely determination of the safest routes and schedules for supply convoys is a critical need for post-conflict operations; however, the computational challenge increases exponentially with the number of destinations and the number of supply convoys. We will combine a form of A* algorithm with a combinatorial optimization algorithm to solve for the best convoy schedules. We will utilize a discrete directed graph with dynamic edge costs that represent a degree of ‘safe-ness’ by incorporating factors which include neighborhood hostility, traffic, and time of day. We propose to develop and compare two combinatorial optimization methods, Simulated Annealing and Genetic Algorithm, to provide timely near-optimal, multiple-convoy to multiple-destination delivery schedules. This work will build upon one of our existing operationally deployed GIS applications featuring an optimization module and routing algorithms. Deliverables will include two performance demonstrations: (a) planning for supply convoy scheduling and, (b) rapid re-planning for the convoy commander. We will also deliver a standalone software application which can be used in live exercises to evaluate the efficacy of the developed technology. Phase II will advance the optimization method and develop the capability as a web service application.

Title:Efficient Thermal Energy Storage (TES) for Mega-Joule Class Weapon Systems
Abstract:High capacity Thermal Energy Storage (TES) systems that can rapidly store peak waste heat using phase change material (PCM) and then dissipate it gradually during normal operation are the most ideal and the most compact Thermal Management (TM) systems possible for advanced weapon systems such as high power laser diode arrays and microwaves. These weapon systems are typically powered cyclically and intermittently with peak requirement potentially reaching up to 1000 kJ/s or 1000 kW per system and with a substantially lower average thermal dissipation requirement during normal operation. Various PCM materials offer high latent heat of fusion and the highest possible thermal storage density. Furthermore, their near isothermal characteristics during the phase-change and re-constitution processes are perfectly compatible with advanced micro-electronic systems that need to operate within a very narrow temperature range in order to achieve the optimal performance. Three different heat thermal energy storage (TES) approaches are proposed for evaluation. The feasibility will be evaluated and critical technical issues will be identified and evaluated in Phase I. A successful demonstration of the proposed technology will lead to full scale development and demonstration for a real system in Phase II.

Title:High-capacity, High-rate Thermal Storage System
Abstract:When the average thermal dissipation requirement is substantially lower than the peak requirement, a thermal storage system is an excellent candidate. The system takes up the brief, high-powered pulse and dissipates it slowly. This strategy shrinks the system and reduces the weight of the system. Depending on the specific application, cycle times may be relatively short, with rates of 1,000 kJ/sec (one megawatt) or greater. An important application is the thermal management of Directed Energy Weapons (DEW) systems. Different phase change materials (PCMs) are needed for different applications. In this project we will develop a high-capacity, high-rate TES that can deliver 1,000 kJ/kg at 20C (laser applications) to 70C (microwave applications) The proposed system can handle a high heat rates (1,000 kJ/sec) and high heat fluxes (e.g., >100 watts/cm2). Several candidate storage materials have been identified that can approach or exceed the goal of 1,000 kJ/kg storage capacity. In Phase I, TDA will perform a system study to select the most promising materials. Laboratory testing will be done to proof the concept and a preliminary design will be prepared. Weight, volume, and power requirements will be determined, and a prototype TES system will be built in Phase II.

Title:Silicon-Modified Nanofibers for Advanced Lithium Ion Anodes
Abstract:Advanced rechargeable battery technology providing higher energy densities and higher specific energies is being sought by the OSD to extend the range and capability of small electronic systems. In this proposal, an anode material is proposed based on carbon nanofiber alloyed with silicon. While many researchers have tested carbon-silicon alloys created through various schemes, these materials suffer always from rapid capacity fade after an initial high capacity. The cause for this rapid diminution in capacity is a large change in volume of the silicon that occurs during charging and discharging, leading to fracture of the material and loss of electrical contact. To overcome this barrier, Applied Sciences has employed a patented process for depositing amorphous silicon onto a carbon nanofiber substrate. Anode materials produced from this combination and tested in a half-cell configuration at General Motors Research Center strongly support achieving anode capacities in excess of 2000 mAh/g with high cycle numbers and charge rates.

Title:Advanced High Energy Density Lithium-ion Batteries
Abstract:The present lithium-ion battery technology needs further improvement with respect to specific energy (Wh/kg) and energy density (Wh/l) for military, aerospace, and transportation applications. The improvement in specific energy and energy density can be achieved by choosing (i) an electrochemical couple having high specific capacity of individual electrode materials and/or (ii) an electrochemical couple having high open-circuit voltage. A new battery chemistry consisting of a novel high practical capacity anode, high capacity, high voltage cathode, and a new electrolyte that can stand up to 5 V vs Li is proposed for the development of high energy density lithium-ion batteries. In Phase I, the proposed materials will be produced, characterized, and qualified for the development of lithium-ion cells. Several prototype lithium-ion cells will be fabricated with the proposed materials anode and their performance with respect to specific energy and long-term cycling will be evaluated.

Title:High voltage and high energy density Li-ion batteries
Abstract:Safe, non-toxic, high voltage and high energy density Li-ion batteries, along with good power density are needed in a variety of military, space and commercial applications. The specific power and energy density of Li-ion batteries can be enhanced by utilizing cathode materials that have higher cycling voltage and specific capacity. We have identified a cathode material composition that can deliver exceptionally high capacity and which avoids using the expensive and toxic cobalt as a constituent in the active material. The innovation in composition is combined with ultrafine particle size to maximize intrinsic and extrinsic Li-ion conductivity of the material, and stabilize the structure against the degradation by the electrolyte at high charge voltages. Working in collaboration with a University partner, first principles computational methods will be used as a pre-screening and explanatory tool for experimentation. Based on the computational results, cathode materials with specific compositions and ultrafine particle size will be produced. Electrochemical properties of cathode materials will be tested in both Li and Li-ion configurations, in partnership with a Li-ion battery manufacturer. In Phase II, prototype batteries will be fabricated and tested for performance, along with optimization and scaling of the synthesis process for producing cathode particles.

Title:Advanced Materials and Chemistries for Electrochemical Energy Storage Devices
Abstract:The objective of this proposal is to demonstrate the feasibility of developing advanced battery chemistries that provide batteries operate safely at specific energies higher than 100 Wh/kg, energy densities over 600 Wh/l. The olivine-type phosphate cathodes are attractive. The stable nature of the olivine-type structure having a PO43− polyanion with a strong P–O covalent bond provides not only excellent cycle-life but also a safe system. Further, olivines are resistant to overcharge and thermal degradation, and are inherently safer than oxides that may release oxygen at inopportune times. The robust covalent bonding of PO43−, however, reduces the compounds’ ionic conductivities, and olivines require additional treatment with conductive aids to perform at reasonable capacities. Yardney Technical Products proposes to develop a high voltage (5V) olivine-type phosphate cathode, and a suitable electrolyte system for high energy Li- ion battery.

Title:Highly Efficient, Lightweight, High Temperature Blower for Solid Oxide Fuel Cell
Abstract:Long-endurance unmanned vehicle (UV) and munition systems require lightweight, compact, and efficient power systems. Advanced fuel cells are promising technologies that can be used for both primary propulsion and auxiliary power units for these applications. A lightweight, high temperature, efficient cathode blower is a critical component to enable a compact SOFC power unit to achieve the high specific power and low specific fuel consumption requirements for long-endurance UVs. We propose to develop a reliable, lightweight, highly efficient blower that can meet the OSD’s challenging performance specifications. The miniature, efficient blower will reduce the take-off weight of UVs and increase their endurance. The innovative blower will be built using Creare’s proven high-speed micro turbomachinery technologies. In Phase I we will prove the feasibility of our approach by modeling performance of the blower and performing proof-of-concept tests. In Phase II we will build and test the blowers and deliver prototype systems for testing in relevant environments.

Title:High-Temperature Blower Development for Solid Oxide Fuel Cell (SOFC) Applications
Abstract:This proposal outlines the design of a very low weight blower system that will provide cathode air for a small ( ~ 2 kW) Solid Oxide Fuel Cell (SOFC) power system. This design (the HTCAB) will derive from a proven blower system that PADT has already developed (LCAB). The improved HTCAB blower system will offer the following advances: 50% more flow, a 10% improvement in efficiency, an 85% increase in power density, a 15% reduction in volume, integration of a sensorless controller, and an increase in allowable inlet temperature to 100C. The aerodynamic improvments be will be built and tested in phase I, but the rest of the changes will be designed and reviewed but not built until phase II. The proposed benefits will be achieved by increasing the width of the aerodynamic flowpath, eliminating the aft bearing carrier, eliminating a number of heat sinks, changing to low density plastic (Ultem)for some parts, changeing to magnesium for the motor housing, and providing space for a sensorless controller.

The cathode air blower is able to operate at very high speeds > 100,000 rpm because the rotating assembley will be supported on foil air bearings. This high speed operation allows for a very small, light weight and efficient air blower which enables more power dense SOFC power systems.

Title:Advanced Hybrid Thermoelectric-Solid Oxide Fuel Cell Energy Conversion for High Efficiency Portable Power
Abstract:The proposal would provide the design and basic product development work to augment the power generation efficiency of fuel cells developed by Acumentrics Corp. by converting waste heat into electricity by highly efficient thermoelectric (TE) power generation. Three paths will be explored in Phase I to add a TE generator to the SOFC. The first will explore the use of a material that is used in commercial products and currently achieves a 6-9% conversion efficiency. The second will utilize a novel material developed jointly by researchers that have demonstrated a 16-20% conversion efficiency with this material in prototype arrays. The third approach will be to amplify the efficiency of the selected TE material by using a novel glass-encased nanowire technique developed by a third company that harnesses quantum confinement to increase efficiency. This technique holds promise both for increasing TEG conversion efficiency and for dramatically reducing the complexity and cost of creating an actual commercial device. The goal of Phase I will be to establish the most realistic pathway to a small SOFC-TE generator that can achieve over 45% combined efficiency when running on light hydrocarbon fuels such as propane.

Title:Advanced Hybrid Thermoelectric-Solid Oxide Fuel Cell Energy Conversion for High Efficiency Portable Power
Abstract:Technology is rapidly advancing both in the area of thermoelectric (TE) modules and solid oxide fuel cells (SOFC). Advanced solid oxide fuel cells are theoretically capable of converting over 60% of the energy available in the fuel (based on the fuels lower heating value) to electricity at operating temperatures around 800 degrees C. The remaining 40% of the energy is converted to heat. With the development of high performance thermoelectric materials, it now appears that a significant portion of the waste heat produced by an SOFC system can be converted into useable electrical energy by thermoelectric devices. An integrated SOFC-TE hybrid, therefore, offers the potential of increased efficiency (lower fuel consumption) than a conventional SOFC. This project proposes a parametric investigation of the integration of the application of advanced SOFC and thermoelectric technologies to maximize the efficiency of a portable power generator with 250Watts of net output power. A laboratory test of a thermoelectric device heated by a solid oxide fuel cell is also discussed. A conceptual design of the integrated 250 Watt SOFC-TE power system will be created.

Title:High-temperature, Electrically-insulating Coating for Magnet Wires
Abstract:In this SBIR project, Aegis Technology proposes to develop a high-temperature, electrically-insulating coating for magnet wires used in electro-mechanical and power conversion components. The development of such coating will enable the resultant components and systems to operate at high temperatures, high power densities and high frequencies, offering the advantages such as high efficiency, small size and light weight. In this Phase I, we are to demonstrate a novel magnet wire insulation concept based on a Si3N4-based ceramic coating material, which can be cost-effectively processed by a polymer-based precursor. With a proper control of processing, it is likely to form a nanocrystalline-microstructure coating with a thickness varying from a few nanometers (thin film) to a few micrometers (thick film). With such a ceramic coating, the insulation properties, thermal stability and mechanical strength can be substantially enhanced, making the resultant magnet wires can work reliably high temperatures far exceeding than 300 C.

Title:Continuous Coating Process for Magnet Wire Insulation
Abstract:In recent decades, advancements in electronic components have led to devices that generate significantly more heat per unit area. The processes by which waste heat is removed are less efficient, and the system must operate at higher temperatures. Magnet wire is a key component in many of these devices, and the durability of the insulating coating is critical to operation at elevated temperatures. Additional stresses on the wire insulation also come from the use of high-frequency, pulse-width-modulation control schemes. The integrity and lifetime of the magnet wire coating is therefore directly related to system performance and reliability. In previous work, Ultramet developed a rapid, low- cost method of applying oxide, nitride, and carbide interface coatings to carbon and silicon carbide fibers at low temperatures (as low as 100°C) through ultraviolet-enhanced chemical vapor deposition (UVCVD). Ultraviolet energy is used to decompose coating precursor gases at much lower temperatures than when thermal energy is used alone. The low temperature process has clear advantages over alternative coating methods because it is not line-of-sight and therefore can uniformly coat intricate shapes such as individual fine fibers. In this project, Ultramet will extend the current technology by applying BN coatings as insulation on magnet wire. The UVCVD process will also be transitioned from batch to continuous deposition, which will further reduce the cost of the coating process. The continuous process will also have increased manufacturing capabilities because it is not limited by downtime between batches or by reactor size.

Title:A Fast Acting Solid-State Circuit Breaker for Electrical Power Systems
Abstract:Increased demands for electric vehicle performance have resulted in large power requirements and the potential for extremely large fault currents. This is true not only for over-the-road electric and hybrid vehicles, but also for ships and aircraft, which are increasingly moving toward all-electric propulsion. Without fast and reliable means to limit fault currents and isolate faulted sections, overall power capacity and mission performance will be constrained. Recent advances in extremely fast (sub-micro- seconds), high voltage and current (hundreds of volts and amps), and high temperature semiconductor switching devices (300 degrees C) provide the opportunity to develop advanced solid-state protection devices. This will allow large loads to be isolated quickly, enabling the move to greater system power capacity. Creare will develop a bi-directional, fast acting switch which can substantially increase electric power capacity. In Phase I, we will demonstrate feasibility with a comprehensive design study and prototype demonstration. We will demonstrate advanced fault management performance, the capability to withstand high voltage and current magnitudes, and an implementation plan that results in a scalable and cost effective protection device. During Phase II, we will demonstrate field operation in military hybrid electric vehicles with our partner, DRS Technologies Inc.

Title:Scalable Solid-State Circuit Breaker (SSCB)
Abstract:Solid-state circuit breakers have significant advantage over electromechanically relays due to the use of various types of solid-state transistors used to control the power flow. These transistors are generally much faster than their mechanical counterparts, switching orders of magnitude, hence allowing superior fault isolation capabilities. Unfortunately, the currently available current and voltage range of solid-state circuit breakers do not cover the specifications for the MEA or Army hybrid vehicle requirements. The limitations of the current solid-state relays are inherent to the fact that the switching transistors are built upon silicon technology. Silicon Carbide (SiC) JFET technology from SemiSouth has the ability to dramatically eliminate this current limitation, and impact near-term revolutionary system insertion opportunities. The optimal solution will be to develop a complete Solid State Circuit Breaker based on this innovative, reliable, scalable SiC Vertical JFET technology. During this Phase I program, SemiSouth will develop leverage existing Air Force funded development and prototype funding of large area 800V/20A SiC VJFET devices to build a prototype 600V/50A SSCB module and provide complete characterization of the module’s electrical characteristics and thermal design space in anticipation of scaling the VJFETs and SSCB design to 1200V and 200A+.

Title:Dropwise Condensation on Hydrophobic Wick Structures
Abstract:The proposed SBIR project will develop an innovative heat transfer mechanism involving dropwise condensation promoted by a non-wetting self-assembled monolayer (SAM) on a porous metal wick. Dropwise condensation on a bare surface has shown the ability to increase condensation heat transfer coefficients by orders of magnitude over film condensation. By condensing on a wick, heat transfer coefficients are expected to be further increased over on bare surfaces because of the increased surface area of the porous metal wick and the more effective liquid removal from the cooled surface by a Laplace gradient mechanism. To promote dropwise condensation on the wick, the wick will be coated with a self-assembled monolayer with low surface energy, to make the surfaces non-wetting to low surface tension fluids such as fluorocarbons and refrigerants. The proposed condensation technology is applicable in pumped two-phase flow devices such as hybrid two-phase loops, passive two-phase flow devices such as loop heat pipes, and gravity aided heat pipes or thermosyphons. In Phase I, we will develop sintered metal wick with SAM fabrication procedure, experimentally demonstrate the improved condensation heat transfer coefficient, perform life test of SAM under thermal loading, and design liquid cooled condenser heat exchanger integrating dropwise condensation.

Title:Advanced Compact Condenser for Electronics Cooling
Abstract:Innovative thermal management approaches are required to address the increasing demand of safely dissipating large amounts of heat from very small electronic component. Removal of waste heat via evaporative cooling technologies presents the best opportunity to enable the integration of high power electronic systems into future military platforms where size, weight, and efficiency are a premium. Advanced cooling technologies, such as microchannel and spray cooling technologies have demonstrated heat transfer coefficients in excess of 105 W/m2K and with low pumping powers. In order to fully realize system level benefits, similar advances in condenser technology are required. Innovative compact condensers are urgently required. A compact high performance condenser requires high and comparable heat transfer coefficients on both the refrigerant-side and the coolant-side. Innovative technologies, such as drop-wise condensation, microchannel cooling, and advanced cooling using high conductivity carbon-based materials are identified for further evaluation on performance, repeatability and durability. Prototype condenser using the most promising technologies will be fabricated and tested.

Title:Compact Condensers for Electronics Cooling
Abstract:To enable the integration of high power electronics into future military platforms, an efficient compact condenser technology which is compact, lightweight, and efficient is needed to remove waste heat from these electronics. Aspen Systems endeavors to meet this need by proposing an advanced condenser design concept which promises to enhance heat transfer on the mini-, micro-, and nano-scales to achieve heat transfer coefficients in excess of 50,000 W/m2-K while minimizing pressure drop. Furthermore, this innovative design concept is compact, low-profile, lightweight, high-strength, and scalable across a wide range of capacities. These benefits are largely derived from its basic flat plate configuration which is manufactured and assembled using modern, reliable techniques. The low-profile, block-like form, and flat footprint allow ease of installation and integration into or on top of electronics enclosures. Aspen Systems is a leader in developing microclimate conditioning systems based upon vapor-compression technology. Aspen develops refrigeration components and integrated packaged systems for electronics cooling and has particular core competencies in micro-channel heat exchangers for both evaporators and condensers. Aspen is well-positioned to support long-term development efforts and commercialization for micro-channel heat exchangers and refrigeration systems.

Title:Ultra-High Heat Flux Condenser for Electronics Cooling
Abstract:Temperature control systems for high-power electronics in future military platforms are likely to use two-phase cooling systems, either in the form of two-phase pumped loops or vapor compression refrigeration systems. Either type of system will require a compact condenser to reject heat from the system. We propose to develop an innovative heat exchanger that couples an extremely compact, microchannel condenser with a very-high heat flux, single-phase heat exchanger. The technology enables very low thermal resistance and uses only well-established, low-cost fabrication processes and can be adapted to a wide range of sizes and form factors. In Phase I we will prove the feasibility of our approach by defining a complete set of specifications for the condenser, designing and building a proof-of-concept condenser, and demonstrating heat transfer coefficients of 50,000 W/m²-K or greater. In Phase II we will design, build, and demonstrate a full-scale prototype to reject 5 kW of heat from a two-phase loop operating at 70°C to a fresh water cooling loop at a temperature of 25°C.

Title:Compact Condensers for Electronics Cooling
Abstract:Mezzo Technologies designs and fabricates micro channel heat exchangers that offer high performance in non phase change applications (gas-gas, liquid-liquid, and gas-liqid). The potential exists or Mezzo's heat exchangers to also provide excellent performance in applications involving phase change (condensers and evaporators). Mezzo proposes a very compact design for the Phase I effort that can serve as the generic platform for an extensive Phase II test program to produce an optimal condenser design. The Phase I effort will focus on modeling, fabricating and testing a condenser. The combination of model prediction and test results will serve as the starting point for the extensive Phase II design effort. Mezzo's design provides the following advantages: 1. Advantages of micro scale passages result in compact, low weight heat exchanger 2. Flexibility in terms of plumbing (i. e. the high pressure refrigerant can be plumbed to allow flow throuh either set of passages). 3. Mezzo's manufacture approach is low cost. This makes it possible to fabricate and test a matrix of heat exchanger designs.

Title:Advanced Condensers Utilizing Microchannel Evaporator Networks (ACUMEN)
Abstract:Described is a highly compact two-phase microchannel condenser concept based on a two-phase loop evaporator design developed for cooling high performance servers in racks on Navy ships/submarines, a novel design that has demonstrated open-air evaporative heat transfer coefficients with water of 250,000 W/m2 K. The idea is to utilize the existing microchannel evaporator design approach -- which combines 20 micron width copper microchannels with a larger pore size low thermal conductivity "supply wick" in a flat form factor -- and apply that same design approach to a microchannel condenser. Based on axially-grooved heat pipe condenser heat transfer coefficients that are about twice those in the evaporator, and cylindrical two-phase loop evaporators that function very effectively as condensers when heat load sharing, proposed microchannel condenser is expected to achieve heat transfer coefficients equal to or greater than the previously mentioned water value. The technology should be highly effective with typical two-phase working fluids, and it can be integrated into a variety of two-phase heat transport systems, including ones that are capillary pumped, liquid mechanically pumped, or vapor compression pumped. The team that successfully carried out the previous SBIR program for the Navy is maintained: TA&T, ATK, B&K Engineering, and Aavid Thermalloy.

Title:Compact Condensers for Electronics Cooling
Abstract:Multiphase heat transfer technology is one of the most efficient methods of waste heat removal in high power electronics cooling. It is especially advantageous where size, weight, and efficiency are the most important factors. A multiphase heat transfer system consists of evaporator, transport lines, condenser, and a mechanical pump in case of an active cooling system. Typically, the evaporative heat transfer coefficients are much higher than the condensation heat transfer coefficients. For example, microchannel refrigerant evaporators exhibit over a hundred thousand W/m2K, while microchannel condensers have refrigerant heat transfer coefficients on the order of several thousand W/m2K. Therefore, the condenser is the limiting component of the cooling system. Improvement of the condenser heat transfer coefficients would allow for reductions in cooling system size and weight. Military systems would especially benefit from cooling systems that are more compact and lightweight. Consequently, the objective of the proposed Phase I effort is to develop a compact and efficient condenser design with a heat transfer coefficients in excess of 50,000 W/m2K. The proposed approach is to utilize the drop wise condensation mechanism combined with a porous wick structure for condensate absorption. The Phase 1 effort begins with technical requirements definition. Based on these requirements, Thermacore will design a high efficiency compact condenser system based upon drop wise condensation and an innovative approach for removal of the condensate. The goal is to avoid film condensation as it is used in conventional condenser systems. In addition, the compact condenser design will be integrated with a loop heat pipe evaporator, processed and thermally tested. Feasibility of the condenser design will be also verified by modeling. The Phase I work will conclude with a demonstration of a 50,000 W/m2K heat transfer coefficient of the condenser system.

Abstract:On-board rotating cryocooling can eliminate a major cost, size, and reliability limitation from superconducting motors and generators. Qdrive acoustic-Stirling sealed, oil-free, and non-wearing cryocooler technology is uniquely suited to rotating service, as demonstrated in a miniature model. This Phase I project will extend the design to ship- power scale coolers, using multiple 2-stage coldheads and will develop integration with superconducting rotor geometry in cooperation with a leading HTS device developer, to establish feasibility and enable full-scale hardware proof in Phase II.

Title:Shaft-Mounted Cryogenic Refrigerator for HTS Motors and Generators
Abstract:Due to their high-power density and efficiency, large-capacity, high-temperature, superconductor (HTS) motors and generators offer a number of advantages over conventional electrical machines for ship propulsion and power generating systems. One of the key practical issues with HTS machines is the ancillary support equipment required to accommodate the low cryogenic rotor operating temperature (~30 K). In particular, cryogenic refrigeration is problematic since available cryocoolers cannot be mounted on the HTS machine shaft, requiring the use of slip couplings to pass cryogenic helium to and from the shaft. The objective of the currently proposed Phase I SBIR project is to evaluate the potential of developing a shaft-mounted cryocooler to eliminate these couplings, as well as reduce the size and mass of the cryocooler. There are substantial constraints on size, weight, and reliability in this application that present significant challenges for most existing cryocooler technologies. Our approach is based on proprietary reverse-Brayton cryocooler technology, which will be unaffected by HTS machine rotation and should provide many other benefits such as ultra-high reliability, light weight, compactness, and flexible packaging. Our approach eliminates the need for an auxiliary cryogenic circulator and can be easily scaled across a broad range of HTS machine cooling requirements.

The APT provides an environment for the partitioning, analysis and the construction of a distributed application. The initial target of the toolkit is the OSD06-IA7 secure coprocessor and application monitor. The toolkit consists of the following components: 1. A Windows based development environment, which is able to work with both source level as well as binary executable representations of target applications. 2. A Portable Executable file format analysis and manipulation module with a corresponding human interface. 3. A C to VHDL translator. 4. A host based interface library for run time linkage of the distributed components. 5. A VHDL compiler and logic synthesis tool chain. 6. Static and dynamic program slicing, analysis and reporting modules. 7. A secure coprocessor embedded software/firmware development environment. A development test-bed that can be used to test, analyze and debug the distributed application. The test-bed will contain an exposed PC (motherboard, hard disk, power supply, etc.), a specially constructed secure coprocessor card with exposed test and probe points, and corresponding documentation for the firmware (Board Support Package), hardware (schematics and data sheets), and development guide. is, partitioning and the construction of a distributed application.

Title:Software Partitioning to Migrate Critical Software Components to Trusted Hardware
Abstract:Despite the increased levels of application security offered by secure coprocessors, the barrier of entry into this realm has been prohibitively high for software developers. Coprocessors do not incorporate sufficient computational resources to host entire applications; therefore it is up to developers to refactor applications by hand in order to derive components that will be tailored to run on the trusted hardware. We propose to ease the transition of software, either in compiled or in source code form, onto secure coprocessor hardware by providing a suit of innovative tools that will automate the software partitioning process, as well as streamline the entire software production lifecycle for partitioned applications from development, to distribution, and finally to execution on client machines. “Secure Division(tm)”, our proposed toolset, will leverage a state-of-the-art program slicer to split software components in a manner guaranteed to be correct, provide high levels of security, and minimize performance penalties. We will include a secure runtime environment in our toolset that is specifically designed to allow dynamic execution of code on the trusted hardware without compromising its integrity.

Title:Binary Level Software Partitioning to Trusted Hardware
Abstract:In this proposal we outline the infrastructure for automating the partitioning/mapping of code snippets and data at the binary level in hardware-assisted software protection solutions. All techniques will be developed with the objective of achieving the highest possible security and flexibility. The approach has several innovative components including the ability to select the critical codes with a graphical user interface at the binary level (including source-level semantic information such as procedure names), the ability to protect applications compiled for various host CPU and HPD ISAs, cross-compilation to HPDs, and support for distributed applications and HPDs. The approach supports both static and dynamic mapping to HPDs: e.g., the HPDs used for co-execution can be dynamically changed at runtime providing additional security and performance benefits.

Title:Software Partitioning to Migrate Critical Software Components to Trusted Hardware
Abstract:Crucial Security will research and develop techniques for the automated partitioning of software systems. The techniques will facilitate a system which can modify the source code or binary form of an application in order to partition user-defined critical code segments for the purpose of running the segments in a separate, trusted, and distributed environments. We will investigate how to determine and define specific attributes that accurately describe a critical code segment while mitigating the occurrence of false positives. Additionally, we will develop techniques to determine the feasibility of running the critical code segments outside of the original software system, based on the operating requirements of the existing piece of software and the environment in which the code segment will execute. Finally, we will develop techniques to automatically parse and manipulate source and binary code in order to meet the conditions required for the code to execute in a separate environment. The end result of Phase I will be a proof of concept utility which will demonstrate the effectiveness of these techniques on both the source and binary forms of a test application.

Title:Software Partitioning for Protecting High-Performance Code
Abstract:Modern devices of all kinds are increasingly dependent upon software, and that software increasingly constitutes a distinct military assert and battlefield advantage. Hardware anti-tamper solutions offer substantial protection for software assets, but can be difficult to apply due to architectural constraints leading to performance or cost tradeoffs. Software partitioning can resolve these tradeoffs by allowing the use of mixed environments combining protected and unprotected hardware. Tranditional program slicing techniques can handle simple partitioning tasks but are not well-suited to software involving substantial loop structure, which is often the most sensitive aspect of the software. In this work, we will enhance the powerful loop transformation and mapping framework present in Reservoir's R-Stream compiler to handle software partitioning for loop-oriented codes. This will make partition-based software protect viable for a broad class of high-performance software, such as signal processing.

Abstract:This project will examine the feasibility of using alternative modes of execution on x86 processors as a means of providing protection for sensitive applications. The research will aim to answer two main questions: 1) can alternate modes of execution provide an environment that is suitable for running an application; and 2) do these modes provide a better level of protection or isolation for the application then what is afforded by the Operating System (OS). Part of this study will also include a detailed examination of the differences between processor modes to identify differences in the observed runtime environment provided to an application (i.e. 16-bit vs. 32-bit operand size, physical vs. virtual addressing, etc).

Title:Utilizing Hardware Features for Covert Loading and Execution of Software
Abstract:Current methods for the covert loading and execution of software typically operate at ring zero or are hypervisor based. Detecting the presence of hidden processes is a cat and mouse game when using traditional kernel-based techniques, and timing analysis and other methods have demonstrated the ability to detect the presence of a hypervisor as well. Modern hardware platforms provide opportunities to execute code completely outside of the context of the operating system. Some of the challenges of covertly executing code on the hardware resources, outside the context of the operating system, involve interfacing with the overlying OS and finding ways to meaningfully interact with it. To fully explore the possibilities of covert loading and execution of software, we must further investigate the approaches for leveraging the hardware resources of a system to execute code covertly. This research looks at BIOS modifications, peripheral cards, and Systems Management Mode (SMM), as well as an investigation into the capabilities introduced with the Extensible Firmware Interface (EFI), and the possibilities for covert code execution using this emerging architecture.

Title:Covert Loading and Execution of Software Protections to Reduce Adversarial Detection
Abstract:A number of software defenses exist that frustrate attempts to examine or tamper with a protected application. However, attackers are unlikely to approach the defenses head-on. One weak point is during installation and deployment of defenses. There is sort of a “who came first” game played between the protected application and the attacker. If the attacker arrives first, then they can observe the defenses as they are setup, gaining great insight into how the protections can be subverted. This opening must be prevented. We envision a technique that enhances existing defenses by protecting the loading phase of the sensitive application. Under this system, attackers are denied access to system initialization and sensitive software is made inseparable from the OS, thereby preventing attack before protection can be raised against it.

Title:Covert Loading and Execution of Software Protections to Reduce Adversarial Detection
Abstract:Pikewerks proposes to research and develop methods to securely load and execute sensitive software modules in a covert manner that cannot easily be defeated by even the most dedicated adversaries. The mechanisms developed will enhance software protection systems by making them more robust against reverse-engineering efforts. Software loading approaches can be divided into pre-boot and post-boot mechanisms. Pre-boot approaches typically include BIOS or boot sector modifications. Post-boot approaches typically include the use of documented OS, user, and kernel driver loading mechanisms as well as undocumented methods such as the exploitation of unpublished vulnerabilities. Pikewerks will focus on pre-boot methods of software loading and covert execution. Research will focus on several different methods of covert software execution, and a prototype will be generated that demonstrates the feasibility of covert loading using either the best method or combination of methods discovered during the research.

Title:A Scalable Cross-Layer Framework for Distributed Trust Evaluation in Sensor Networks
Abstract:Wireless Sensor Networks (WSN) are popular due to the fact that they are potentially low cost solutions to a variety of real-world challenges. However, the unreliable communication channel and unattended operation makes security difficult and multiple attacks have been discovered. Research has gone into securing the network using efficient key distribution and management mechanisms but use of a single shared key in the WSN is not a good idea because an adversary can easily obtain the key and is processing intensive. A mission using a sensor network can be considered successful if a response to a query is obtained with a high degree of reliability. By attaching ratings to each node based on their interaction with other nodes, trust levels can be maintained based on ‘reputation’ with other nodes. The trust level provides a way to categorize query-forwarding as reliable or not. We propose to develop a system that provides a ‘trust level’ mechanism that effectively rates a node’s interaction with its neighbors, provides a scalable solution for large-scale networks, and provides a set of ratings that are an accurate representation of the interactions between nodes in response to a query. The system can be deployed as a software/middleware solution.

Title:Agent-based Trusted Querying Framework for Wireless Sensor Networks
Abstract:Corresponding to the increasing trends of using sensor network for the daily operations in both commercial and defense sectors, designing an efficient query processing mechanism for wireless sensor networks has also been paid attentions. While recent research efforts on database based query processing approach dramatically improves the efficiency of query processing, another critical component, security, is still missing. In reality, the sensor networks are expected to be deployed in various hostile environments, for example, battlefield, and these unattended wireless sensors are faced with a variety of risks and can easily be hijacked or compromised. Intelligent Automation, Inc. (IAI) proposes a novel Agent-based Trusted Querying Framework (ATQF). The intent of this work is to incorporate theories of trust from social networks into sensor networks in order to provide a trusted query processing infrastructure that returns the highest-fidelity response to the end-nodes of a sensor network. One significant difference between the proposed approach and traditional reputation-based trust models is that the trustworthiness is not only evaluated from the Reputation, but also takes the Risk into account. We will show that adding the Risk value into the trust management model make the scheme more efficient and accurate.

Title:Learn to Trust Thy Neighbor: Proactive Trust Management System (PTMS) for Wireless Sensor Networks
Abstract:Wireless Sensor Networks (WSNs) are systems that may contain hundreds to thousands of low-power and low-cost sensor nodes. The potential applicability of such systems is enormous and includes environment monitoring, security surveillance and intrusion detection, monitoring chemical plants for safety, wireless body area networks, among others. As WSN technology matures, an increasing number of such systems will be deployed in real world, hostile environments. As a result, WSNs will be the subject of a wide variety of possible attacks. While the different basic cryptographic building blocks and hardened hardware architectures currently available for most WSN platforms allow protection on a single node basis, once a node has been compromised, such building blocks are not efficient in preventing wider scale attacks. To that end, UtopiaCompression (UC), in conjunction with its consultants Lockheed Martin and Prof. Mario Gerla, proposes a reputation-based solution: Proactive Trust Management System (PTMS) for WSNs. Our innovative solution is specifically designed to address resource constrained WSNs and is based on temporal and spatial outlier detection mechanisms as well as on a Dempster Shafer theory based reputation system. During Phase I, UC will produce a simulated prototype of our system and validate its performance through comparison with alternative approaches.

The proposed approach has a unique combination of services and capabilities that go much beyond state-of-the-art to assure network edge trust and to provide end-point trust-based management/authorization of security features in a networked distributed environment such as envisioned for the GIG.

Title:Entropy-Trust-Homology Operational Security (ETHOS)
Abstract:Secure and semi-secure distributed networks rely on static security protocols and certificate authorities to attempt to assure trust between network participants. Trust is based on what others initially think of the participant and not on what the participant actually says or does. Trust should be based not only on initial impressions but also on subsequent participation in the network. KBSI proposes an Entropy-Trust-Homology Operational Security (ETHOS) method of securing trust based on the information that is exchanged between the different edges of the communication network. Trust entropy metrics would be developed based on the pattern of information entropy flow between edges and on usage behavior. The metrics would be updated by a hardware device residing at each edge. The hardware device would use graph-based data mining techniques to update the metrics and autonomically collaborate with other edges in a distributed manner. The distributed collaboration would result in a secure, verifiable network where trust is based on what the edges do rather than solely on who the edges say the are.

Abstract:In order for the DoD to leverage the advantages enabled by network-centric operations, it is critical to ensure the quality of the information that feeds decision-making processes. The ability of an enemy to compromise network elements in order to inject spurious information must be viewed as one of the biggest threats to missions supported by network-centric operations. In this research project we will develop an open architectural framework, along with a supporting protocol stack, that allows the trust associated with network elements to be evaluated and acted upon within a networked environment. This will include a sophisticated semantic technology service that may be out-of-band to previously established operations, and allows subjective information to be incorporated into trust calculations. We will also provide an analysis of the security of the overall architecture.

Title:Trusted Data Distribution with Privacy Protection and QoS through Auditable Anonymity
Abstract:Currently deployed network security solutions focus on protecting authenticity and integrity, but NOT privacy and anonymity. And, current anonymity technology cannot be leveraged to rectify this situation for net-centric warfare infrastructures like GIG because it does not support highly dynamic services effectively. Also, no existing anonymous systems support vital, enterprise-class features such as QoS and pseudonymity via secure logging. “Bluemoon”, however, is an entirely new, privacy-preserving architecture that leverages innovative anonymous “hook” technology to solve these challenges. A recently developed Bluemoon prototype already provides full unobservability and unlinkability for both data sources and destinations, as well as greater security and flexibility than any current-generation offering in the field. The proposed SBIR research will yield a version of Bluemoon, dubbed “Enterprise Bluemoon”, that includes enhancements in QoS and secure logging, and provides a total solution for preserving privacy and anonymity in high assurance, dynamic networks. This proposal describes: (a) the existing research that has gone into creating Bluemoon technology and building the initial prototype (which already meets many of the requirements for a Phase II product) and (b) the enhancements we will develop to effect Enterprise Bluemoon, which addresses all five of the IA gaps identified in the QDR.

Abstract:As the SBIR RFP requests, we plan to develop the concepts for innovative IA tools & techniques and study the feasibility that the tools/techniques will guarantee the authenticity, integrity and delivery of distributed data sources while maintaining the privacy (anonymity) of users and audit information (pseudonymity) per the Common Criteria within the GIG-NCES (Global Information Grid - Net-Centric Enterprise Services) framework. Our approach will be to study the feasibility of deploying a family of services that aid the Warfighter and other designated “roles” by tailoring the implementation of Information Assurance (IA) technology to proactively support and enhance their mission tasks. Without understanding the unique challenges faced by Warfighters in different contexts, IA can represent a costly burden by consuming his resources while leaving a trail for the enemy to use to decipher his mission intentions. Many times the Common Criteria (CC) has been viewed as a necessary evil that slows system development and adds cost, but clever planning can turn the CC into a real benefit by protecting the Warfighter in the conduct of his mission.

Title:SPANS: Software Protection using Anti-tamper and Network Security
Abstract:US software is constantly being attacked by enemies in attempts to reverse engineer the software to extract useful information, military secrets, and intellectual property. This SBIR proposes a solution to this problem: multiple software guards and a secure, efficient communication channel for the exchange of attack information. Six aspects of our proposed solution are especially unique: 1) multiple information assurance-based techniques to protect software applications, 2) multiple anti-tamper-based techniques to protect the integrity of the application’s network information, 3) inter-guard communication based on proven, efficient wireless transmission techniques and covert channels (preventing divide-and-conquer attacks), 4) separate guards providing different anti- tamper techniques (including third parties techniques), 5) stealth corruption to destroy software functionality without alerting attackers, and 6) exclusive use of the solution for the DoD, DHS, and their contractors. The complete solution will be an automated tool that incorporates this advanced protection into the software development process. In Phase I, a preliminary version of the system will be developed. To show feasibility, several security engineers will perform reverse engineering attacks against the solution. In Phase II, we will add automation and integration with third-party techniques and conduct extensive testing of the solution.

Title:Information Assurance and Anti-Tamper System Level Protection for Unattended Network Nodes
Abstract:McQ designs and develops remote unattended sensor systems for DoD and other applications. As part of our on-going research into anti-tamper, information assurance (AT/IA) and reverse engineering techniques, we have developed a battery of processes that can help to insure that our systems are less vulnerable to attacks by an adversary. Many of these processes are extensible to the GIG-NCES at-large. For this project we plan to extend much of what we have done already in the realm of opcode encryption, communication encryption, physical protection, device authentication, user authorization, automated tamper protection and other techniques to improve their performance and usability. We also plan to further explore a host of other areas with which we have experience and expertise such as system restoration. Because of our experience with unattended ground sensors, remote weather stations, roadside monitoring systems, remote acoustic monitoring systems and other networked automated remote monitoring systems, McQ brings “real world” perspective while using the latest in security and cryptographic technology to assist in the IA/AT challenge that is presented to GIG-NCES systems. Our goal is to ultimately demonstrate the features of a comprehensive IA/AT security plan and system design using our OmniSense® family of networked remote sensor systems.

Title:Novel Information Assurance and Antitamper System Based on Collaborative Intelligence
Abstract:To address the OSD need for innovative tools and techniques that will guarantee the integrity and authenticity of data within the Global Information Grid Net-Centric Enterprise Services (GIG-NCES), Physical Optics Corporation (POC) proposes to develop a new Service Architecture for Tamper-Resistant Software Components (SATSOC) system. This proposed system is based on aware software components, aware application service environments, intelligent event monitoring systems, knowledge-based tamper detection, an antitamper bus, and a central antitamper detection and penalization system. The innovation in collaborative and net-centric intelligent systems and multimode wireless networks will enable the SATSOC system to prevent or delay reverse engineering attempts, strengthen protection layers of GIG-NCES nodes, and seamlessly merge information assurance and antitamper approaches into a unified technique that enables policy-driven management of GIG-NCES node security. In Phase I POC will demonstrate the feasibility of the SATSOC system by assembling and testing the components. In Phase II POC plans to develop a prototype to demonstrate how our approach solves information assurance and antitamper problems, by integrating the SATSOC system into one or more unmanned GIG-NCES nodes and interfacing with C2 systems.

Title:A Trusted Platform Security Management for Data Authenticity and Integrity
Abstract:For tactical networks, a need exists to allow a node to determine the trust level of another node or network resource in order to determine whether it can be used for a specified purpose. In the case that a resource’s trust level is below an acceptable standard, it may be necessary to determine whether the resource can be repaired or isolated. To address this problem, it is desirable to extend this approach to a system of information assurance layers and anti-tamper layers to strengthen the level of protection. This effort will develop a Trusted Platform Security Manager (TPSM) that can be used to meld information assurance and anti-tamper concepts into a single platform. The resulting TPSM will provide improved data integrity, data availability, data authentication, and data storage as an out-of-band solution via multiple layers of protection. RAM Laboratories will partner with a large system integrator, Lockheed-Martin, to define a path to fielding this technology in an operational setting. The TPSM will target platform applications including forward-deployed small Unmanned Aerial System (UAS) surveillance platform, which includes multiple sensors, mission computer, and computing algorithms.

Title:Information Assurance and Anti-Tamper System Level Protection
Abstract:The “smart dust” micro-radio concept developed by DARPA provides an outstanding demonstration of the potential of distributed micro-sensor networks connected by low- power radio frequency (RF) data links in a self-organizing network. Distributed micro- sensor and control networks are poised to become a major component in the global information grid (GIG), and have vast potential in DoD and Homeland Security applications such as border security and nuclear/biological/chemical (NBC) threat detection sensor networks. GIG node products are now being manufactured for commercial applications, however, these initial devices do not yet address the important issues of security, robustness, and tamper resistance that are necessary to deploy these devices in mission-critical applications. In Phase I Athena will directly step from the current generation of GIG node products to produce a robust, secure GIG node, called Black Dust, that provides defense in depth through an innovative combination of single-chip module anti-tamper features and information assurance techniques.

Title:Variable Thrust, Kerosene Fueled, Tactical Rocket Motor Development
Abstract:Busek proposes the development of kerosene/JP10 fueled small rocket motor suitable for tactical and in-space applications. The motor design and the choice of oxidizer will be driven by the requirements for broad and rapid motor throttleability, arbitrary number of absolutely reliable restarts without the use of hypergolic mixtures, performance comparable or better than presently available solid motors of comparable size, 10 year storability without performance degradation, low or no toxicity, and environmental requirements typical of tactical systems that may exclude oxidizers with freezing point significantly above that of JP10. To meet such a list of requirements Busek proposes innovative fuel flow rate regulation system capable of millisecond responsiveness, and innovative fuel atomization approaches to ensure reliable starting without hypergolic mixtures and high energy igniters. In Phase 1 Busek will develop a conceptual design of a liquid motor with the above described attributes using the Sidewinder motor as a reference against which the design will be evaluated. A subscale motor will be designed, build and tested in Busek facilities with the goal to validate the innovative fuel atomization augmented with electrospray techniques combined with electric ignition system. In Phase 2, Busek will work with a major prime that is currently supplying tactical motors.

Title:AVATAR Multi-Role Morphing Missile
Abstract:Gloyer-Taylor Laboratories has identified a suite of technologies that can provide a tactical missile with a high degree of energy management capability and proposes to demonstrate these technologies by developing the AVATAR (Adaptive VAriable Trajectory Attack and Reconnaissance) Multi-role Morphing Missile. The 9-inch diameter by 13-foot long AVATAR missile is sized to be air launched from nearly any combat aircraft, including F/A-22, F-35, F-15, F-16, UCAS and bomber, using the BRU-61/A pneumatic carriage, or ground launched from the MLRS using the standard M26/M31 tubes. AVATAR provides long range precision strike capability, thereby extending the reach of existing combat systems. AVATAR technologies include the safe, non-toxi, long- term storable, high-performance GTV monopropellant, the efficient Highly Integrated Modular Structure (HIMS), and a revolutionary morphing structure. To manage the combustion stability risk, the breakthrough Universal Combustion Device Stability (UCDS) process will be used. UCDS accurately predicts the stability characteristics of the engine at any throttle setting and provides the physical insight needed to mitigate potential instability issues. The AVATAR technologies provide enhanced energy management capabilities, while addressing key historical impediments.

Title:Variable Thrust Liquid or Gel Propulsion for Mission Flexibility
Abstract:ORBITEC proposes to develop a family of liquid/gel propellant, variable thrust propulsion systems to provide increased mission flexibility to battle planners to enhance warfighting strategies and enemy engagement capabilities. Variable thrust capability with non-toxic, space-storable propellants is also paramount for in-space applications such as rendezvous and docking Effective variable thrust capability is ideally achieved without loss of propulsion performance so mission efficiency is retained, and without loss of mixture ratio so that a propellant residual is not a consequence of throttled operation. In the proposed ORBITEC approach, which builds upon their evolution of Vortex Combustion Cold Wall (VCCW) chambers, performance and mixture ratio are essentially retained over the throttle range. A goal of 10:1 throttle range appears feasible. ORBITEC proposes to include both liquid and gel propellants in their program, and to undertake the development of the complete propulsion system including propellant tankage and pressurization. The resulting system is a self-contained autonomous propulsion package that needs only thrust level commands from the missile guidance package to perform its operations. In Phase I, the system will be defined and the lead system sized and analyzed. Key elements of the system will be demonstrated in laboratory testing. The conceptual design for the system to be proposed for Phase II will be prepared. In Phase II, a breadboard system will be hot fired to demonstrate operation and throttle range.

Abstract:Our vision for the next generation missile propulsion is a flexible and non-toxic system using HAN and a storable fuel candidate, offering variable thrust with a high degree of mission tailoring. Additionally, such system will be capable of rapid transients to enable pulsed propulsion for tactical missions. To meet the rapid start and shutdown transient goals, we propose an innovative injector manifold design capable of reducing trapped propellant by as much as much 70% as compared to traditional designs. We will perform parametric systems and combustion analysis to characterize mass fraction and Isp sensitivities for candidate systems.

Title:Variable Thrust Liquid or Gel Propulsion for Mission Flexibility
Abstract:XCOR is proposing to study the combination of desensitized nitromethane (CH3NO2) and gaseous oxygen (GOX) as a propellant combination. Nitromethane has a density of 1.14 and the amount of low density oxygen needed for stable combustion is very low. Compared to nitrous oxide and ethane, this combination has higher density, and a greater range of storage temperatures. What is innovative about this approach is the combination of using desensitized nitromethane for better storage and handling properties, along with a new, small and light spark igniter, and just enough gaseous oxygen to permit reliable ignition and stable combustion of the fuel. Nitromethane has long been recognized as a high performance monopropellant, but is too sensitive for real-world tactical handling. If this fuel is desensitized for safety, it no longer works as a monopropellant because the catalysts no longer work. Adding oxygen to desensitized nitromethane and using spark ignition, making it a true bipropellant system, eliminates these problems at the expense of greater system complexity. Since a very small amount of oxygen is needed, the overall system density is reasonably high.

Title:Rocket Propulsion Supporting Technology
Abstract:Refractory carbide materials posses the erosion resistance and high temperature strength required for the severe environments experienced by cutting tools, well bore equipment, and rocket nozzles. Refractory carbides (e.g. WC, TaC, and TiC) are usually formed by press and sinter techniques with an additional metallic binder or by forging with some binder. We propose fabricate ceramic metal matrix composites by melt processing, where the carbide phase and the metal phase are formed by eutectic reaction from the liquid. In this new family of materials the low temperature binder phase is replaced with a refractory metal phase, thereby increasing the high temperature strength of the composite, while maintaining room temperature ductility. This innovative approach is possible because of two recent technological advances: Advanced Powder Solutions’ nano encapsulation of ceramic powders by chemical vapor deposition and net shape laser additive manufacturing practice at the University of Tennessee Space Institute. The techniques allow us to synthesize these advanced materials into useful net shape parts.

Title:Solid Rocket Motor Propellant Characterization and Material Reconstruction Using High Resolution Tomography
Abstract:Material characterization and volume imaging of as-produced solid propellant grains are important issues in the design process of solid rocket motors. In particular, it is critical that the ballistician have tools that will enable him/her to understand any defects or morphological changes in a grain that might be caused by the manufacturing process, as well as the determination of bulk thermomechanical material properties. We therefore propose to develop software tools for volume imaging and three-dimensional reconstruction of as-produced propellant grains from tomography volume-imaging techniques; develop computational tools that can model the morphology of the propellant grain, including first-, second-, and third-order statistics; and develop computational tools that can determine initial material properties, including elastic modulus, effective thermal conductivity and coefficients of thermal expansion, etc. These tools will be validated by comparison with experimental data.

Title:Diagnostic Ultrasound for Structural Health in Solid Rocket Motor Components
Abstract:The degradation of solid rocket motor components due to aging has a significant negative impact on mission success for both aerospace and military applications. Luna, in teaming with Aerojet, will assemble a specifications database including appropriate ranges of material properties and geometries of individual SRM components to help focus the efforts to relevant applications. Using Aerojet-supplied samples, Luna will apply its high resolution ultrasonic measurement capability for materials characterization of critical SRM components. Measurements of ultrasonic velocity and attenuation including stress/strain dependence will be made in order to assess shear and elastic moduli, as well as, third order elastic/viscoelastic properties. These measurements will be made under the context of their relationship with age related effects and become the foundation for the development of a numerical model of ultrasonic guided wave propagation in multilayer cylinders. This model will be used to optimize sensitivity and determine appropriate inspection parameters. Proof-of-concept testing on strain relief cylinders will evaluate this technique’s capability for assessing reduced modulus propellant and propellant-liner disbond in practically applicable samples. The results of this Phase I effort will lay the groundwork for a diagnostic measurement system capable of assessing the structural health of SRM components.

Title:Foam-Based Ignition System for Non-Toxic Propellants
Abstract:Hydroxylammonium nitrate (HAN)-based propellant promises many improvements over hydrazine and NTO/MMH propellants. Chief among these is improved safety, which will significantly decrease overall use costs. However, reduced toxicity monopropellants are difficult to ignite. Although this characteristic is an asset for safety, it is a liability for design. Before HAN-based propellants can be commercialized, a reliable ignition system must be established. Ultramet has completed several projects for DoD and NASA directed toward the development of an ignition system for HAN-based monopropellants that have led to many key advances. The goal of the proposed effort is to reliably ignite HAN-based monopropellants by using a variation of resistojet technology based on resistively heating Ultramet foam. Ultramet will develop an ignition system consisting of open-cell foam made of refractory materials that can be heated resistively and can then transfer thermal energy to the propellant stream to initiate decomposition. Ultramet will characterize the electrical and thermal characteristics of several refractory foams and demonstrate ignition characteristics using spot plate testing and hot-fire testing on test engine sizes appropriate for kinetic kill vehicle divert and attitude control system and microsatellite attitude control system applications. In follow-on work, pino testing, macrodifferential thermal analysis, and additional hot-fire testing would be performed.

Title:Variable Thrust Hybrid Propulsion for Mission Flexibility
Abstract:A novel type of high burning rate hybrid rocket fuel is an enabling technology for a wide range of DoD rocket propulsion applications. This fuel system has been demonstrated to provide burn rate at least four times that of conventional polymers, while retaining the physical properties and specific impulse capability of HTPB based fuels. The result is a high density impulse capability utilizing storable propellant combinations, while eliminating environmental hazards. This fuel maintains a hydrodynamically rough surface to radically enhance convective heat transfer rate, and hence the fuel burn rate. This is achieved by incorporating a particulate fuel material dispersed within a continuum phase polymer matrix. The dispersed fuel material is chosen to transition from solid to gas much more readily than the polymer matrix, and with a particle size scale sufficiently large that the resulting surface voids provide a hydrodynamically rough surface. Combustion of this fuel system maintains the rough surface as theparticles are continually exposed. Secondary effects include increased surface area; decreased fuel phase change enthalpy; and potential for increased specific impulse by inclusion of high energy compounds. The high fuel burn rate enables increased propellant mass fraction while retaining the strength and storage stability of polymeric fuels.

Title:Variable Thrust, Multiple Start Hybrid Motor Solutions for Missile and Space Applications
Abstract:Energy management in missile systems can provide substantial performance advantages, especially for modern missiles capable of all-aspect engagements. Maximum flexibility is offered by a system that can be throttled, shut off entirely and restarted when needed. The proposed project aims to achieve efficient combustion during throttling and restart capability without the need for a separate ignition system that adds to a vehicle’s mass and complexity. The innovative approach outlined in this proposal will utilize the catalytic decomposition of an oxidizer to enable flexible hybrid propulsion systems while also addressing both the low regression rate and slivering issues in hybrid rocket motors for missile or space launch applications. The Phase I effort will focus on generating conceptual designs of identified missile and upper stage propulsion systems, developing and assessing the performance and ignition characteristics of catalytic fuel grains for the oxidizers of interest, and experimentally investigating throttling capabilities and the fundamental control laws to achieve the desired thrust control. This research and development effort will be assist by the research and rocket testing facilities at Purdue University and the internal ballistics and combustion expertise at General Kinetics.

In Phase I, physical properties and performance of the specific identified compounds will be determined to provide data for ranking the candidate fuels. Theoretical performance with selected fuels will be calculated and compared to baseline performance using SOTA oxidizers. The system-level benefits of propulsion systems using the new oxidizers will be quantified by comparison to existing systems. Hot-fire test plans for Phase II will be developed and initial synthesis of several candidate compounds will begin toward the end of the Phase I period.

Title:Nytrox/Paraffin-based Hybrid Propulsion for Mission Flexible Systems
Abstract:Space Propulsion Group, Inc (SPG) proposes to conduct investigations on Nytrox/paraffin-based hybrid rocket systems which promise high energy flexible propulsion solutions with high volumetric fuel efficiency while retaining the safety and cost advantages of classical hybrids. The benefits of the proposed hybrid concept result from a combination of two key SPG technologies: high-regression rate paraffin-based solid fuels and high performance Nytrox oxidizers which are refrigerated mixtures of nitrous oxide and oxygen. The high regression rate capability simplifies the fuel grain design, minimizes fabrication costs, improves fuel volumetric loading and reduces the fuel sliver mass fraction to less than 3%. The major advantages of Nytrox oxidizers are 1) higher density, Isp performance and safer operation compared to N2O, 2) partial self pressurization, non-cryogenic operation compared to LOX. Nytrox/paraffin based hybrids are ideal for systems that require operational flexibility due to the possibility of active throttling with very small performance penalty, a direct consequence of the relatively flat c*-O/F curve. Phase I work has two major components: 1) propulsion system design/optimization studies with emphasis on mission flexibility and 2) small scale motor testing to demonstrate the throttling and gas phase combustion with gaseous oxygen at the end of the liquid burn.

Title:Solid Propellant Thrust Control Using a Movable Nozzle
Abstract:Thrust management in a SRM-powered missile system allows the missile to successfully engage a wider range of targets, and a given propulsion option to be applicable across a range of missile platforms. Thrust control in a SRM is performed by controlling the choked throat area at the nozzle throat. Previous research has accomplished this by moving a pintle back and forth through a fixed nozzle. CFDRC proposes to reverse this paradigm and explore the movement of the nozzle in relation to a fixed pintle. Issues arising from this approach include sealing against hot gas in more places and potentially large actuation forces. There are engineering approaches such as pressure-balancing, which CFDRC has used with success in other programs that will be applicable here. CFDRC currently has identified three separate concepts for moving the nozzle that are promising. In Phase I, CFDRC will examine each of the three actuation approaches and weigh the cost and performance benefits. The Phase I will end with CFDRC testing at least one concept in a room-temperature actuation rig. In Phase II, the best-performing actuation concept will be developed into a flight-configured motor. CFDRC will team up with a propellant supplier to complete a working motor and it will be test-fired.

Title:High Performance Pulse Motor for Mission Flexibility
Abstract:Although solid rocket motors (SRM) are ideally suited to many propulsion applications, their lack of controllability restricts their mission flexibility. Following ignition of an SRM’s propellant grain, combustion continues until all propellant is consumed. Controllability of the motor’s thrust profile can provide improved missile performance and multi-role capability. One approach to gaining controllability is to use a pulse motor configuration, in which multiple solid propellant grains, physically separated by a barrier, are ignited individually, and burn independently, thereby providing multiple, discreet thrust pulses. Past development programs have proven technologies capable of providing thrust management but have not entered service mainly due to reduced propellant mass fraction and resulting loss in total impulse. A need exists for advanced materials and processes to overcome these performance losses and provide pulse motor thrust management payoffs at affordable cost and with high reliability and safety. Cornerstone Research Group Inc. (CRG) proposes to demonstrate feasibility of a high performance solid rocket pulse motor based on a modular design approach, with bonded end closures, incorporating innovative materials and manufacturing processes. Low cost, reliable manufacturing processes, coupled with advanced, lightweight, high performance materials, will provide the capability to achieve the desired thrust management and resulting performance enhancements.

Title:Low Cost Reliable Dual Diameter Throat (DDT) for Multiple Mission Missiles
Abstract:Multiple mission missile architectures typically use a two-pulse rocket motor with inter- pulse coast capability. The technology currently used to accomplish this is a two pulse barrier motor with a single axial nozzle that delivers both the first and second pulse impulse. To optimize impulse performance it is desirable to have a two position axial nozzle throat that maintains its geometry during the first pulse and reduces the throat area for the second pulse. Valley Tech Systems has designed a simple, passively activated, easily producible single piece throat insert called the Dual Diameter Throat (DDT)to perform this task. The DDT is a simple passive component that increases the second pulse packaged impulse while minimizing recurring cost as compared with other two position throat concepts. Our Phase I program will study various DDT candidate configurations as applied to a selected advanced multiple missile propulsion system architecture. Requirements will be generated that meet the transient ballistic requirements of both rocket motor pulses. A combination of mechanical design, thermal and structural analyses will be accomplished to assist in this evaluation. A recommended DDT concept will be selected with a more detailed conceptual design accomplished. In addition subscale testing of key technology will be accomplished during the phase I program to demonstrate the feasibility of the DDT technology.

Title:Liquid Atomizing Fuel Injector for Heavy Fuel Internal Combustion Engine
Abstract:Rapid fuel droplet evaporation and near-homogeneous mixing with air can be obtained with small monodisperse droplets, bringing benefits to the performance of combustion chambers, and reduced pollutant emissions. Additionally, the greater homogeneity of the mixture produced by fine atomization permits operation at higher equivalence ratios, improving stability. Current fuel injector technology utilizes a high pressure (thousands of pounds per square inch) feed system driven through orifices to generate polydisperse fuel droplets. The quest for droplet size reduction has led to common rail systems operating at as high as 29,000psi. Such systems do not scale well to small engine applications due to their size, weight, and complexity. Busek proposes to investigate a novel approach for creating monodisperse micron-sized droplets at the mass flowrates required for a small heavy fuel internal combustion engine (ICE). Busek will accomplish this without the need for excessively high fuel feedsystem pressures currently used available injector systems. Busek has already achieved the desired droplet sizes and performed successful combustion testing of unmodified JP-8 at low mass flowrates. The goal of the Phase 1 effort shall be to test an augmentation technique for increasing mass flowrates, culminating in a proof-of-concept functional and characterized fuel injector.

Phase I will culminate in submission of a Phase II plan that defines the effort necessary to implement charged heavy fuel injection within engines ranging from 5 hp to 200 hp. All upgraded engine electrical systems, power required, mechanical components and injector detail designs will be fully compatible with JP5, JP8 and diesel fuel operation. During Phase II three prototype engines (approximately 10 hp, 100 hp, and 200 hp) will be configured with charged fuel injection and demonstrate efficient for heavy fuel operation at reduced ambient temperature and pressure levels. Our proposed coordination with multiple small engine developers through interaction with a Blue Ridge Diesel will accelerate transition of charged fuel injection into numerous commercial products.

Title:Micro Fuel Injection (FI) for Small, Heavy Fuel Engines
Abstract:Kinetic BEI intends to design, build and test MicroJectors during this SBIR Phase I contract. A first generation prototype of the MicroJector currently exists. This SBIR would provide the opportunity to expand on previous work, fine-tuning the mechanical design of the miniature fuel injection system and bench testing second-generation prototypes. During this effort, spray patterns will be evaluated and CFD analysis will be conducted. With a mass of 33.3g, the MicroJector weighs less than half of the nearest fuel injector on the market. The MicroJector measures just 1.880” in length with a fuel pressure of 4,000 psi. Other advantages include low power consumption, excellent atomization, simplicity, and electronically-controlled variable injection rates. While some work has been accomplished in this area, more research is required. The opportunity to expand the research and development of this miniature/micro fuel injection system through a dedicated SBIR program will have far-reaching implications in both the military and commercial worlds. The MicroJector proposed in this Phase I has already demonstrated strong potential. Funding through this SBIR would provide the opportunity to add fidelity and advance the technology to a point where it can be utilized on current miniature engine development programs.

Title:Development of a Fuel Injection System for Very Small Internal Combustion Engines
Abstract:The U.S. Department of Defense is currently seeking micro fuel injection (FI) systems for very small, heavy-fuel internal combustion engines (ICEs). These small engines are required for lightweight, low volume applications such as unmanned aircraft systems, unmanned ground systems, and unmanned maritime systems. Fuel injection plays a key role in determining the useful work that can be extracted from the combustion process in these engines as well as the exhaust gasses that are emitted from the engine. As power density requirements and emission regulations are increased, new fuel injection technologies need to be developed beyond that of what is currently available. The major limitation with the current technology is that it is not capable of delivering sufficient amounts of fuel while distributing the fuel well throughout very small volumes. In an effort to overcome this limitation, Mainstream proposes to develop an innovative fuel injection concept for small heavy-fuel engines. During the Phase I effort mainstream will experimentally validate the benefits of using the proposed configuration using an actual heavy-fuel military diesel engine manufactured by Mainstream. In Phase II, Mainstream will take what was learned in the Phase I effort and use the information to develop a prototype injection system.

Title:Development of a Supercharger for Small, Heavy Fuel Engines
Abstract:The OSD is seeking devices to increase the intake air flow and pressure to small engines in order to increase their power density and fuel efficiency, specifically for unmanned applications. Such unmanned systems require high efficiency and highly reliable power sources operating at near continuous duty cycle. By increasing the power density of these engines, they can be used in a larger variety of applications under various operating conditions. This includes high altitude flight for aircraft systems and extreme environmental conditions for ground-based and naval surface and subsurface systems. In this proposal, Mainstream presents a Phase I program to design, fabricate, and test a supercharger suitable for use in small heavy fuel engines. Mainstream will performance- test the device on its own 4-hp engine. This accelerated development program will validate the concept experimentally in Phase I. The Phase II program can therefore focus on the integration and long-term testing on OSD’s specific engine application.

Abstract:Proposed is the preliminary design of an extremely small turbocharger sized for an 8 to 12 hp class engine. The entire unit will weigh roughly 240 grams. Design will incorporate pre-existing compressor and turbine designs for which hardware currently exists for Phase II test. Phase I will include design, fab and test of a 450,000 rpm, high durability, low-cost bearing system. Risk is medium to low since shaft speed, compressor performance and turbine performance have been demonstrated in test. A preliminary turbocharger design for PHase II fabrication and test will be generated. M-DOT will collaborate with UAV and engine makers in the design of the Phase II turbocharging system such that Phase II will culminate in the fabrication and test of a turbocharger and wastgate on an engine and potentially in a vehicle.

Title:Micro-ignition Components for Heavy Fuel Engines
Abstract:Precision Combustion, Inc. (PCI) proposes a durable miniature catalytic glow plug as an enabling component for the use of heavy fuels in small, high power density engines for unmanned applications. The use of heavy fuels in such engines will have a major impact on availability of fuel supplies for such small engines while also reducing fuel consumption through the gains in efficiency inherent to high compression engine operation. The hot, reactive catalytic surface of the catalytic glow plug will allow ignition of fuel-air mixtures at lower surface temperatures and compression ratios than required for non-catalytic hot surface igniters, and at extended conditions. This will expand the envelope of durable ignition and operation, and will provide a range of enabling benefits for heavy fuel use, including more rapid starting and better operability, lower required compression ratio, improved ignitor life, reduced energy requirement, and overall reduction in system weight and size compared to higher voltage ignition systems. It will help enable heavy fuel use in unmanned applications, support increased fuel economy, and reduce system cost. PCI’s work will build on substantial prior development of catalytic ignition systems.

Title:Micro Fuel Pumps for Small, Heavy Fuel Engines
Abstract:The proliferation of small, unmanned systems has established a nascent market for small, lightweight power plants, including both internal combustion engines and turbine systems. Recently, researchers have successfully developed breakthrough technologies in this market, such as the Meyer Nutating Engine. While the underlying combustion technology has been proven, one limitation is that all commercially available support components, such as fuel-pumps and fuel injectors, are bigger than the base engine itself. Novel re- design of these required components is needed to realize the potential of power plant innovations for unmanned systems. Axis Engineering Technologies, in collaboration with Kinetic-BEI, proposes to develop an active material based fuel pump for use on a small, lightweight engine. In Phase I, two competing active material systems will be developed simultaneously, based on both piezoelectric ceramic and ferromagnetic shape memory alloy actuation. The side-by-side development of these competing technologies in Phase I shall yield a superior technology to carry forward into Phase II hardware development.

Title:Micro Fuel Pumps for Small, Heavy Fuel Engines
Abstract:Kinetic BEI and Beginning Technologies Inc. have designed a very compact and simple micro-injection pump. This SBIR Phase I will provide the opportunity to further advance this emerging technology for use on several current miniature/micro engine development programs for the military and commercial worlds. The pump was designed to provide high pressure supply to common rail type injectors on a 10 mm3/injection fuel flow rate, and to be paired with a new MicroJector, also being designed by the Kinetic BEI and Beginning Technologies team (a Phase I proposal for further development of the MicroJector has been submitted under OSD81-UM1). The advantages of this pump design include small size, light-weight, low part count, and elimination of the rail pressure sensor, rail pressure control actuator, and the rail. In addition, the electronic control circuitry is simplified because the pump control loop is not necessary. To date, funding has been provided through engine development programs. The opportunity to focus specifically on development of this pump through a dedicated SBIR will yield tremendous benefits for both the military and commercial worlds. During this Phase I effort, detailed design work would be completed incorporating design improvements, and a prototype pump would be developed and bench tested.

Title:Implementation of Unit Injectors in Small, Heavy Fuel Engines
Abstract:The U.S. Department of Defense is currently interested in obtaining small engines that are lightweight, reliable, durable, fuel efficient, and low cost for many applications. Some of these applications include providing propulsion and power generation for small unmanned aircraft systems (UAS), unmanned ground systems (UGS), and unmanned maritime systems (UMS), with power requirements in the 8 kW range. Engines of this size will require smaller components that may not be commercially available, such as ignition systems, fuel injectors, and fuel pumps. For fuel injection systems, it would be beneficial to use unit injectors, which combine the fuel pump and nozzle into one unit and allow for much higher fuel injection pressures in a smaller package, improving performance while reducing components and weight compared to conventional systems. Mainstream proposes to develop small unit injectors that would be applicable to small, heavy fuel engines for military applications. First, Mainstream will integrate existing commercial electronic unit injectors into one of Mainstream’s existing large engines and design a control strategy to maximize performance and efficiency. After the benefits of unit injection have been demonstrated with bench-scale tests and simulation models, design of the smaller unit injector for engines in OSD’s 8-kW target power range will follow.

Title:Micro Fuel Pumps for Small, Heavy Fuel Engines
Abstract:A micro fuel injection system has been proposed to mix fuel and air directly in a combustion chamber quickly and in a controlled fashion to promote efficient and clean combustion. A system constituting of a high pressure fuel pump system, injector(s), distribution lines, injector drivers and control harness would support this micro fuel injection system. A novel pump design (using traditional elements) has been developed to support these fuel injector systems. Miniaturization of traditional fixed clearance pumps sized for the 5-200HP (30lb Thrust Class Inclusive) engine ranges has seen limited efforts. While high performance pumps exist, engine applications have not emphasized the need for miniaturization. Innovative engine technologies coupled with the high performance and small foot print needs of military and aerospace applications are driving the expansion of the technology envelope for optimized lower flow miniaturized pumps. Low flow/high pressure applications define a corner of the pump market that has been met through pump over sizing. This pump design is optimized for the aforementioned low flow applications. Particular attention has been paid to internal sealing, component tolerances, and performance optimization. Specifically, geometry considerations at the pump inlet allow for greater fill pressure and thereby higher altitude operations and performance.

Title:Micro Fuel Pumps for Small, Heavy Fuel Engines
Abstract:Turnkey Design Services, LLC of Blue Island, IL proposes to create a small lightweight “smart” fuel pump for unmanned vehicles using a small very efficient brushless motor with integrated controls and an internally-generated rotor pump. The overall size of the motor driven pump including electronics is about 2.5 ” long x 1” diameter. The proposed pump provides flow metering capability by adjusting the motor speed. The proposed motor uses high energy density rare earth magnets and specially designed windings to create the best efficiency for the required operating range of the pump. The controller is sensor less in order to eliminate the need for hall effects which take a significant amount of space. The smart pump is capable of monitoring and transmitting its current health status, as well as monitoring sensors for use in its internal control algorithms. The smart pump would be able to determine its rotary position, drive the pump to the commanded rotary speed (or flow), while managing its speed within a certain tolerance.

Title:Integrated Power Generation for Small Unmanned Vehicles
Abstract:This program will improve the size, weight and efficiency of power generators by integrating a lightweight, high efficiency alternator with a quiet, fuel efficient and high power density heavy fuel engine. It will be capable of meeting DoD needs for reliable and efficient propulsion and power systems for unmanned aircraft, ground and maritime systems. The electrical power source will use a proprietary, compact and very high power-to-weight alternator using rare earth permanent magnets. It is scalable from 0.5 to 15 kW and larger. This electrical power source could also be adapted to other conventional engines if desired. The alternator will be fully integrated with an internally supercharged Migrating Combustion Chamber (MCC) engine. Microprocessor controls will provide for load following and stabilized power at varying loads. Electronic controls will allow the use of the alternator for starting the engine. The MCC engine’s mechanism and cycle of operation allow it to operate on low octane fuels like diesel and JP-8 without auto-ignition, detonation or wet stacking. This engine provides full expansion of the combustion gases inside the engine which increases efficiency and produces a very quiet, cool exhaust. The MCC engine is scalable from 2 HP to over 200 HP.

Title:Integrated Power Generation for Small Unmanned Vehicles
Abstract:The purpose of this program is to reduce the size, weight, and improve efficiency and reliability of the power generation system for UAV’s. The approach taken will not only accomplish this goal, but provide on board starting with virtually no weight or cost penalty (for systems with onboard starting there will be a tremendous size and weight reduction). There are four key components of this approach which will be analyzed. High pole count, high energy permanent magnet brushless technology will be used to provide a single integrated device for the purpose of starting small internal combustion engines in the 30 lbs thrust class and power generation. Advances in power electronic technologies, allows for the miniaturization of the conversion device to provide power for driving the starter and regulating the generator voltage. Direct to shaft mounting eliminates the need for any intermediate mechanical devices (e.g. gears, belts, couplings and clutches). Minimizing the size of the starter motor will be accomplished by reducing peak torque requirements of the internal combustion engine. We will analyze the effect of compression release and system inertia. These technology developments will focus on the rotary engine application, and can be expanded to include reciprocating and nutating machines.

Title:Integrated Power Generation for Small Unmanned Vehicles
Abstract:The ever increasing utilization of unmanned air, ground and maritime vehicles has dictated the need for the DoD to more effectively integrate the generation of electrical power with the propulsion engine associated with unmanned vehicles. This issue applies equally to turbine and IC engines. The problem could be considered more vexing in the case of small turbine engines since the maturity of this integration is at a much lower level than an IC engine counterpart. Military assets that could immediately incorporate Spytek’s proposed ITB/generator technology are the Global Hawk and other small UAV’s of similar mission requirements which have increasingly greater electrical power demands, but largely on an intermittent basis i.e., electronic warfare attacks. The integration of a generator and an Inter-Turbine-Burner (ITB) between the gas generator turbine and an electrical generator turbine could meet this warfighter demand. Leveraging its previous AFRL sponsored work on Ultra-Compact Combustors and inter-turbine burners, Spytek Aerospace proposes to design and build a fully integrated ITB/generator module mounted to one of its existing gas turbine engine designs.

Abstract:Under this Phase I SBIR, Baker Engineering will conduct research through modeling and simulation for optimization of heavy fuel micro rotary engines. Research will be conducted using the UAV Engines Ltd. (UEL) model 74-1380 as the basis. Such a rotary would be the ideal engine for military engine applications that require high power density and the capability of running on heavy fuels at low specific fuel consumption levels. Utilizing the current state of injection technology and simulation software, accurate performance models can be established. Computational fluid dynamic (CFD) analysis and zero dimensional modeling will be utilized to refine advanced fuel delivery methods, rotor geometry, and evaluate induction configurations. A fuel injection system will be designed, and turbomachinery added. The result is a plan for successful operation of a micro Rotary Engine on heavy fuel with SFC of .35 lb/hp-hr.

Title:Modeling & Simulation for Optimization of Heavy-Fuel Micro Rotary Engines
Abstract:The Department of Defense (DoD) is currently seeking strategies to provide efficient and dependable power systems for small unmanned systems. The engines must run on heavy fuel, be lightweight, produce high horsepower and have the ability to run in extreme environmental conditions. New technologies are needed to meet the DoD’s requirements for small, heavy-fuel engines, including injection systems, ignition components and air induction systems such as superchargers and turbochargers. Development of these new technologies can be greatly facilitated with the use of computational fluid dynamics and combustion modeling, however most codes are not able to adequately handle rotary engine concepts. With the development proposed in this program, the CONVERGE code, written by Convergent Science Inc., will be able to efficiently and accurately simulate rotary engines and also unconventional engine concepts such as the Nutating engine. Proposed objectives include adding the ability to handle sealing of adjacent surfaces, adding an arbitrary equation of motion for moving boundaries, and adding liquid properties for JP5 and/or JP8 fuel. These capabilities, coupled with the automatic and rapid grid generation of CONVERGE, will provide a tool that can be used in the design and optimization process of rotary engines operating on heavy fuel.

Title:Modeling & Simulation for Optimization of Heavy-Fuel Micro Rotary Engines
Abstract:This program will conduct analytical studies to demonstrate how to convert the AR-741, rotary engine, to run on heavy fuel. Specifically, CFD modeling will be used to show how direct injection/stratified charge can be employed to convert this engine to heavy fuel. The direct injection will avoid predetonation, while the stratified charge or layering of the fuel air mixture will be investigated for a "lean burn" characteristic to achieve the best fuel economy. Further, the spray pattern will show a rich fuel mixture at the point of ignition for sufficient starting ease. The effects of turbocharging will also be modeled to achieve the desired SFC of 0.35. Thermodynamic cycle analysis will be used as a first order attempt to show the benefits of turbocharging and increased compression ratio on SFC. Computational Fluid Dynamics (CFD) will be used for the combustion design; showing the optimum location for the fuel injectors/igniters, spray pattern, mixing, and the corresponding combustion process. CFD will be used to determine optimal rotor pocket geometery and the investigation of the benefits for "split" combustion chamber operation. Lastly, we believe that in order to achieve the desires SFC of 0.35 lbs/HP-hr turbocharging will be a neccessity.

Abstract:Yotta Navigation proposes to develop the SOCOM divePDA a rugged, secure, high-precision, handheld real-time navigation and communications system suitable for military operations. This system will take advantage of Yotta’s existing expertise in several areas: network security, inertial (INS) and differential GPS-assisted navigation, user interface design, above- and sub-surface communications, efficient integration of components from mainstream suppliers, and our deep knowledge of real-time systems. Yotta’s modular, extensible approach will bring consistently reliable sub-meter dynamic positioning, depth and attitude, full-duplex voice, high-data rate throughput in excess of ten (10) hertz, and the ability to track horizontal and vertical position even in the total absence of GPS. This solution also features innovative security and low probability of detection (LPD) techniques. Because the proposed SBIR solution can be built around an existing Yotta divePDA solution platform and architecture, a field-testable prototype system is achievable by the end of the Phase I. This Phase I effort will culminate in a high-quality proof-of-concept design, testable prototype, and quantifiable performance results. The approach will also permit significant time for testing, optimizations and enhancements during Phase II. The primary tracking device will maximize the use of recent advances in commercial-off-the-shelf (COTS) Micro-Electro-Mechanical Systems (MEMS) technologies. It will be extensible and allow for future anticipated GPS Modernization improvements, especially the evolution of military P(Y) capable devices to support M-Code.

Title:Deep Submergence Rated Flexible Hoses and Piping System Connectors
Abstract:Connecting deep submergence systems (submarines) in the field can be a dangerous and difficult task. The rigid piping systems used today have little flexibility to accommodate for variations in connection points and differences in tolerances between vessels. Atkins & Pearce, a 200 year old textile processing company, has developed a technology that uses a multi-layered approach to create a high pressure hose that is extremely flexible. Inspired by the human body, A&P’s technology uses a braided substrate in conjunction with high strength reinforcement rings. Taking existing technology and expertise in the field of fiber science, A&P developed the innovated concept of using compression resistant coils to withstand external pressures and a braided sub-structure to contain internal pressures. A&P’s technology combines burst protection, compression resistance, flexibility, and the ability to attach to a variety of connection points. The system can eliminate unnecessary spare parts and make the job of connecting Deep Submergence Systems easier and safer. Potential civilian applications include offshore oil platforms, deep-sea science research and other underwater systems.

Title:Deep Submergence Rated Flexible Hoses and Piping System Connectors
Abstract:The objective of this proposal is to demonstrate the feasibility of developing flex hoses for hydraulic and other piping system interfaces that can withstand high pressure environments, hydrodynamic, and other forces unique to deep submergence system operating environments. This hose and connecter system coined FlexiHOSE© proposed by MEI-Charlton, Inc. (MEIC) will meet the need of operating under deep submergence operating environments with extreme hydrostatic and dynamic pressures. This will be achieved by both design optimization and material choice in engineering the hose and connector system proposed here. A super alloy braid sandwiched within polymer layers will be the basis of the FlexiHOSE©. The desired properties of the selected materials are high strength, high impact toughness and fracture toughness to tolerate the high level of stresses generated due to high internal pressure vary from 1 atmosphere up to 4,500 PSI.. The mockup prototype flexible hoses proposed here will range between one foot to ten feet in length, and from 1/2 to 4 inches in diameter (inner). The hoses will be designed to contain hydraulic fluid or diver quality air. The hoses proposed here will be able to withstand pressure differentials (internal to external) of up to 6,500 PSI (threshold) and 7,000 PSI (objective). In addition to accommodate the external pressure variations the hoses design will withstand pressure differentials (external to internal) of 1,000 PSI (threshold) and 1,100 PSI (objective). The hose ends will be standard nine inch bolted flange connections with a single O-Ring and the hose flange connections will rotate freely relative to the hose body.

Title:Embedded Sensor System to Provide Superior Structural Health Monitoring of Fairing Panels
Abstract:Swimmer delivery systems, externally mounted on submarines, are subject to hydrodynamic flow and irregular wave-slap loads. These result in unsteady, alternating impacts that can damage exposed surfaces. It is important to track the cumulative stresses imposed on the fairing panels to provide operators with a sense of the remaining service life of the panels. Fairing Panel failure could be catastrophic to operations. Since surface mounted sensors can become damaged or dislodged during normal operational use, there is a need to develop a reliable, durable embedded sensor system. In order to be able to make accurate measurements from embedded sensors, these challenges must be dealt with: (1) Sensor movement during the manufacture of composite, (2) Survivability to high temperature/high pressure composite manufacturing environments, (3) Compatibility of composite materials and sensors, and (4) Ability to make “measurement calibrations” to compensate for the effect of 3-D stresses. In this proposal, Acellent will address and overcome all of the major challenges faced for embedding stress/strain sensors within Fairing Panel composites. Acellent’s unique "SMART Layer" technology has been demonstrated to securely embed sensors, keeping them from moving, during the cure of composites. This advanced technical ability will be used as a basis for this development.

Title:Distributed Sensing System for Health Monitoring of Deep Submergence Vehicles
Abstract:Deep submergence vehicles must perform in demanding marine environments to safely and effectively carry out special operations. These vehicles are subjected to damaging hydrodynamic and wave impact loading that may weaken or fail the structure. Luna Innovations proposes a distributed health monitoring system to monitor localized strain and damage within the vehicle’s structure and predict its remaining service life. The embedded sensing system promises to integrate seamlessly within existing vehicle structure and/or within the manufacturing processes of future composite marine structures. The sensing system will be small and light and will have no damaging effect on the mechanical properties of the material being monitored. The sensor system will provide unmatched resolution to accurately measure the strain throughout the entire structure and pinpoint the presence of damage before it compromises the structure’s integrity. Composite durability testing will be carried out to develop material specific prognostic models and algorithms to provide operators with data on the loading history and predictions of the remaining service life.

Title:Speciation, Identification and Quantification of Atmospheric Gases
Abstract:Accurate speciation and measurement of the composition of air environments in Navy submersibles is vital to crew safety and health. This proposal focuses on the development of a detection system specifically for collection, speciation, identification and quantification of gas phase chemicals found aboard submersibles. The proposed hybrid sensor system will be approximately 1/10 the size and cost of traditional bench top analytical instruments and will be capable of unmanned sample collection and battery-powered operation without compressed gas. We believe no single chemical detector technology will be able to serve the solicited detection requirements. The proposed system will utilize multiple sensor technologies to meet the requirements of the solicitation, including chemicapacitive, metal-oxide, and electrochemical sensors integrated with a preconcentration/chromatography system; thus combining selectivity from a diverse array of sensors with a miniature sampling system for amplified sensitivity. Specific components include: a vapor collection pump, a gas sampling loop, sample preconcentrator capable of quick heating and in stages, capillary column for separating chemicals released from the preconcentrator, providing selectivity, integrated array of chemical sensors including chemoselective chemicapacitors, chemiresistive metal-oxides, and electrochemical sensors, and integrated touch screen computer.

Title:Lightweight, Compact Atmospheric Gas Sensor
Abstract:SRD will develop a miniaturized atmospheric gas sensor array and design a gas analyzer (sensor analyzer module, SAM) capable of accurately detecting and autonomously monitoring critical atmospheric gases in enclosed spaces. In this Phase I effort, SRD will use its current, existing technology (miniaturized sensor platform, proprietary SMO sensor coatings and advanced signal processing algorithms) and make appropriate engineering modifications to meet the environmental background challenges specified by the solicitation. O2, CO2, CO and TCA will be detected and identified in real-time, in a continuous monitoring mode at pressures ranging from 1 to 6 ATM, temperatures of 32 to 105 degrees F, and a wide range of humidity. The low power requirement of the sensor array and supporting electronics will lead to rapid development of a lightweight, portable, waterproof atmospheric SAM, suitable for environmental monitoring and atmospheric control applications aboard small submersible vessels, within piping systems or adapted for use in atmospheric monitoring and control of UBAs. The portable gas analyzer will be used as an autonomous real-time gas monitor with the option of linking multiple analyzers together with wireless communication to create a distributed environmental gas monitoring network.

Title:Improvements to Sense and Avoid (SAA) Systems for Unmanned Aircraft Systems (UAS)
Abstract:There is no Sense and Avoid (SAA) solution for small UAS such as Scan Eagle, Raven, or BATMAV, which represent by far the greatest number of UAS. Equipping small UAS with SAA capability is problematic, mainly due to the very small size, weight and power (SWAP) resources available. The SAA system must compete for critical SWAP resources with fuel and payload sensors. Small, low-power EO and sensors do exist, but these typically have much lower resolution and sensitivity as well as analog-only video outputs, which seriously degrades their utility for intruder detection and processing. Additionally, EO sensors have no capability at night, except against illuminated aircraft; this may be fine for civil airspace operation, but is problematic for Air Force SUAS which train and operate almost exclusively with covert aircraft. Defense Engineering Corporation (DEC) has devised an innovative solution for this challenging problem based on state of the art sensor and algorithm technology. The Defense Advance Research Agency (DARPA) is developing the Micro-Sensing for Imaging (MISI), a high-sensitivity, high-resolution, infrared imaging device weighing less than 10 grams. The DEC team will embed intruder detection and avoidance algorithms directly into the MISI sensor to create an effective SAA solution for small UAS.
