| 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. |

| 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. |

| 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, laser welding, manufacturing, and laser researchers. |

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. |

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. |

| 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). |

(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. |

| 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. |

| 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. |

| 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. |

| 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. |

| 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. |

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 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. |

| 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 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. |

| 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.

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. |

| 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. |

| 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 the different defect types, and provide the required sensitivity. |

| 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. |

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. |

| Abstract: | This Phase I SBIR project will develop a tool-less direct core fabrication technology based on ceramic stereolithography. 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. |

| 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. |

| 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. |

| 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. |

| 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. |

| 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.

| 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. |

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. |

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. |

| Title: | Fusion of Vibration and Oil Debris Sensor Data for Improved Engine Bearing Health Management |
| Abstract: | Safety incidents due to failure of rolling element bearings in aircraft gas turbine engines are a significant cost to the Department of Defense. Oil debris monitoring (ODM) has been shown to be effective as an early indicator of engine bearing faults. 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. |

| 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 |

| 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. |

| 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. |

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. |

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. |

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.

| 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. |

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. |

| Title: | Health Management Tools for Rocket Engine Turbomachinery |
| Abstract: | Frontier Technology, Inc. (FTI) will develop innovative modeling tools, sensors, and signal processing for the prediction of the health of rocket engine turbomachinery. The ultimate goal is real-time health management technology capable of monitoring turbomachinery performance. The benefit is reduced turnaround time and increased safety and availability for reusable rocket engines. Health management technology can quickly identify faults or abnormal conditions in an engine following use and can ensure that it has been restored to a normal health state prior to return to service. 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: | Advanced Microwave Electrothermal Thruster for Dual-Mode Water Rocket Propulsion (AMET-DMWRP) |
| Abstract: | ORBITEC proposes to develop the Advanced Microwave Electrothermal Thruster (AMET) for use as one of the primary thrusters in the Dual-Mode Water Rocket Propulsion system. The AMET uses an electrodeless microwave discharge to produce thrust from water vapor propellant, delivering specific impulse in excess of 800 seconds with a highly efficient process. Microwave energy is introduced to a resonant chamber via an antenna; the microwave energy is refocused by the chamber at a location immediately upstream of the nozzle. Water vapor (steam) propellant is tangentially injected into the aft (left) half of the resonant chamber, and swirls inward towards the nozzle. A plasma discharge in the water vapor is established at the focal point adjacent to the nozzle, facilitating the transfer of energy from the oscillating microwave energy to the water vapor prior to its expulsion from the nozzle to produce thrust. Microwave electrothermal technology is the only known option for delivering high Isp (over 500 seconds) from water. BENEFIT: Taken by itself, the AMET is an attractive propulsion technology in its own right. In the context of the integrated Dual-Mode Water Rocket Propulsion system, it becomes even more appealing when compared to currently available in-space propulsion technologies, with the advantages of mission flexibility, high performance, and zero toxicity. ORBITEC foresees the DoD as being the first key customer to use DMWRP systems, which will be applicable for most orbiting vehicles with significant in-space propulsion requirements. Once the technology has been demonstrated, ORBITEC intends to broaden its marketing efforts to include both commercial and NASA customers.) |

| 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. |

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.

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.

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.

| 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 |

| 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. |

| 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.

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.

| 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. |

| 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. |

This work will build on existing algorithms for developed for vehicle control and sensing the complex urban environment developed by NAVSYS and researchers at MIT. The proposed approach will provide adaptive non-linear flight control algorithms that can provide hover capability for fixed wing aircraft. This approach allows the advantages of fixed wing aircraft speed and flight distance to be combined with the surveillance advantages of hovering craft. Under Phase I we will: extending the robustness of existing flight control algorithms for the extreme flight dynamics that can be anticipated in the urban environment by incorporating adaptive model reference control; extending the development of dynamic trajectory planning used successfully in MIT’s Grand Challenge vehicle to MAV applications; using new, computationally efficient, feature extraction algorithms that will allow robust navigation through the complex urban environment for collision avoidance even when GPS signals are unavailable or degraded. Under Phase I we will develop the algorithm design and provide simulation results to demonstrate the expected performance of a system to be flight test under Phase II. |

| 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. |

| 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. |

| 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. |

| 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. |

| 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 and Response System (JSARS), Situation Awareness Fusion Integrated Research Environment (SAFIRE), Space C2, ISSA, and Rapid Attack Identification Detection and Reporting Systems (RAIDRS) programs. In addition, the proposed effort will drive the development of our EAToolkitTM commercial product, an evolutionary algorithm software development kit for optimization and machine learning. |

| 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 structures must also be designed and optimized for the new thin cell technologies. These lightweight solar arrays must provide significant advances upon the specific power of the array, while still retaining the stiffness requirements for launch and on-orbit attitude control maneuvers. |

| 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 to $750M annually, yielding a high return on investment for commercial infusion of the proposed technology. In addition to the aforementioned tangible performance benefits the reduction in solar array mass and stowage volume will reduce launch costs, minimize satellite dynamics/controls overhead, and enhance orbital maneuvering capabilities. These intangible benefits will provide affordability and improved capabilities for future high power missions. |

| 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. This new scrubber device will have the performance options that will allow it to provide scrubbing capability to a myriad of FPGA devices. If this goes forward, this new architecture will also include fault injection capability which will allow the user to synthetically test the mitigation technique against the simulated faults based on environmental requirements for the end application. This feature will reduce the need for radiation testing which is becoming increasingly difficult in new technologies and advanced systems. Using the Structured ASIC as the fabrication medium will make the scrubber inherently radiation hardened. Above the hardware benefits from the component development is the software simulation capability for benchmarking architectures and circuits. This will also provide a good demonstration of a reconfigurable computing architecture for use in high end computing 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. |

| 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. |

| 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 support systems such as Space Situational Awareness Fusion Intelligent Research Environment [SAFIRE] program, BMDS system, Future Combat System (FCS), Joint Strike Fighter (JSF) program, JSSEO program, and AEGIS program. DCM and Lockheed Martin are building a mentor- protégé program. We will leverage this relationship to identify the end customer, and work with these teams to transition our technoloy into their program. The DOD contact who knows the details of our work and who knows the above programs is Dr. Erik Blasch from AFRL. Other potential commercial applications include inter-satellite communications, multi-layered sensing, disaster assessment, air traffic control system, the national weather service, physical security systems, law enforcement agency, emergency control center, border and coast patrol, pollution monitoring, remote sensing and global awareness. We expect the aggregated market size will be similar to that of military applications. |

| 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.

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. |

| 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. |

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. |

| 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: | Cuming Microwave Corporation (CMC) has formed a team which is uniquely suited to perform the tasks required to fully demonstrate, characterize, and validate an on-aircraft mold in place (MIP) technology for aircraft coatings. Our team has already demonstrated the ability to apply thick coatings to complex shapes in confined spaces, while reducing cost and cycle time as well as eliminating VOC’s. The CMC Team has demonstrated all the technical elements required to successfully scale-up and demonstrate their MIP technology for aircraft validation. All the technology elements have been demonstrated to a Technology Readiness Level (TRL) of six. Because all the various technology elements are relatively mature, all that is required is manufacturing scale-up, system level technology integration and demonstration/validation of suitability for aircraft production. This high TRL maturity provides a low risk program for the Air Force. |

| Title: | Direct Part Manufacturing (DPM) for Nonstructural Components |
| 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. |

| Abstract: | Ridgetop Group, Inc. will develop a unique and innovative capacitance-only switching power converter with efficiencies over 99%. Power efficiency and battery life are vital concerns for the modern war-fighters who rely on portable electronic technology to enhance their effectiveness. Batteries used for radios, rangefinders, and night vision equipment contribute weight and reduce net carrying capacity. The proposed monolithically integrated power supply unit will alleviate this burden by providing ultra-high efficiency DC-DC conversion in a small package. Weight reductions will be achieved in required batteries and conversion electronics. Achieving small package size and efficiencies above 95% are extreme challenges for a conventional inductive switch-mode power supply. Ridgetop will develop a capacitive-only switching supply based on a charge-pump and charge capacitor approach. Recent advances in semiconductor processing, including low-power, high-voltage devices, will enable new designs to achieve efficiencies greater than 99%. |

| Title: | High-Speed Surface Measurement Device |
| Abstract: | Weather conditions that may affect the design of missile radomes, windows and leading edges include the presence of rain, snow/sleet in the atmosphere and sand during missile flight trajectory. The Tri-Service Agencies Weather Encounter Advisory Group led by AMRDEC is organizing tests to study the detailed fracture mechanics of brittle ceramics radome material in free flight. In this proposed work we will develop a dynamic holographic interferometry technique to measure dynamic surface deformations of a fast moving missile. Specifically, we will analyze and evaluate different optical methods, and design experimental holographic interferometry set-ups for measuring deformations of a missile radome moving in a rain field or in a sand cloud. We will be using combined approaches of digital holography and analog holography. Initially, we plan to use CW analog holographic schemes with a controlled shutter that will allow performing analog holographic interferometry using thermoplastic holocamera or photorefractive materials. Also, parallel methods using digital holography and digital holographic interferometry will be used. Finally, we will develop numerical models that analyze analog holographic interference patterns and digital holographic interferometry results to infer changes in surface map of the radome due to deformations. |

| Abstract: | To address the Army need for high-speed measurement technique for weather impact damage assessment of projectile IR domes and radomes, Physical Optics Corporation (POC) proposes to develop a new Holographic Light-in-Flight Interferometric Camera (HOLIFIC) three-dimensional imaging sensor based on short-pulse dynamic holographic recording of a projectile in flight. The innovation in the integration of light-in-flight holography with the short-pulse holographic interferometry will enable the proposed sensor to provide an optical inspection of surface roughness and deformation of a high- speed object. As a result, this system offers simultaneous measurement of surface profile and deformation over a wide range, instantaneous (light-speed) recording, high- resolution, low-noise images, and full-field 3D surface profile. The holographic 3D image recording and interferometry will be in real time using an erasable permanently placed holographic recording medium in a ruggedized camera system. In Phase I, POC will design a HOLIFIC sensor, analyze its performance, and demonstrate the proof-of-concept by laboratory experiments. In Phase II, POC will fabricate a full-scale, HOLIFIC system and integrate it with data collection, 3D reconstruction and deformation analysis software. The prototype can be produced at relatively low cost, compared with high-speed CCD- based system, and will require a minimal setup and calibration time. |

| Title: | Solid State Infrared Flare |
| Abstract: | The use of night vision equipment on the battlefield is a well documented success, and under some conditions an infrared flare may enhance this advantage. Currently, US armed services use the M-278 Infrared flare rocket to this end. The objective of this effort is the development of a replacement for the M-278 Infrared Flare using LED technology. The operational difficulties of the present system are related to the poorly controlled chemical combustion nature of the source. A solid state LED-based technology upgrade is ideal as it does not generate high internal temperatures, has high reliability, and can be engineered to radiate no energy outside the desired band (700-1100 nm). The Infrared LED flare system will be comprised of an energy storage system, control electronics, power regulation, cooling system, LED emitter array, beam forming optics, and mechanical support envelope. LED testing will be performed to drive devices into the extreme high output regimes, which are atypical of most LED applications, while measuring photometric, distribution and lifetime data. The requirements, possible solutions and integration will be investigated for the optical, power, thermal, and control systems. |

| Title: | Semiconductor Laser Packaging for Infrared Flares |
| Abstract: | Flares are routinely used for battlefield illumination or for identification of hazards and landing strips. Visible light flares are simple in concept and execution, but have the disadvantage of being easily visible by anyone within visual range. Infrared flares enable the covert use of illumination, utilizing the advantage of modern Night Vision Goggles and can help enable today''''s war fighter to operate in the dark. In this proposal is outlined a design approach and preliminary systems analysis for an infrared laser diode based infrared flare system. Laser diode devices offer the highest efficiency and highest optical power density of any semiconductor based light source. nLIGHT''''s design capabilities for MIL SPEC laser diode packages, electronics, battery packs, and mechanical housings enable us to be highly confident that the presented design will satisfy the systems performance and cost requirements. |

| Abstract: | In this Phase I SBIR proposal Physical Sciences Inc (PSI) outlines the development a solid- state emitter package to replace the propellant based candle of the M278 Infrared flare. Propellant combustion in the current candle technology is unsteady, resulting in variations in the illumination intensity and also produces a visible signature that limits it usefulness in covert activities. The proposed flare technology will use solid-state components (Light Emitting Diodes or laser diodes) to generate Infrared illumination that will overcome these limitations of candle illumination. In the Phase I, PSI will develop a prototype design for the solid-state emitter package that is compatible with the current dimensions and weight of the M278 candle. The design process will include: 1) Emitter component characterization and selection, 2) optical system design to combine the output of multiple emitters to achieve the specified output radiance intensity (250 W/sr), 3) Evaluation and selection of a power system to drive the emitters and control circuitry and 4) Preliminary mechanical design that integrates these components. In Phase II the prototype will be built and tested, both in the laboratory and in the field. |

| Abstract: | The Army and other services use the M278 Infrared flare rocket that uses an illuminant candle to provide illumination compatible with night vision gear. Recent advances in solid state lighting offer the potential to replace the burning candle with a solid state illumination source. Princeton Optronics proposes an approach using a newly developed technology of VCSELs which offer many advantages over alternative approaches for illumination application. In phase I, we would conduct a feasibility study on our approach to providing a solid state replacement for the candle in the flare rocket. The study would include a detailed analysis of the approach including electronics, optics, and power. Operating alternatives, such as high speed pulsing, would also be investigated. Limited destructive bench tests of the VCSEL arrays to drive them into the extreme high output regimes while measuring photometric and lifetime data would be performed. By the end of Phase I we would have a proposed design for a solid state replacement for the infrared candle meeting the Army specifications. In phase I, we would also build an early prototype version of the package which can be tested by Army before the end of the phase I. The first build will use one of our VCSEL arrays of >200W of power at 976nm. In phase II, we would develop a benchtop demonstration prototype with a form factor of the solid state infrared flare. Measurement of the optical, electrical, and lifetime characteristics of the prototype would be conducted. Experiments to show that the prototype design would survive the shock environments of the M278 rocket would also be performed. In Phase III, we would finalize the design for production of the solid state flare replacement. Live fire demonstrations would be conducted in phase III. |

| Title: | Polarimetric Sensor for Air-to-Surface Missile Systems |
| 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 from a single focal plane in wavebands spanning the visible through the long wave infrared. Furthermore, this device is non- lossy and extremely compact. Bodkin Design and Engineering, LLC (BD&E) specializes in the development of compact thermal imaging cameras with zoom capabilities, miniature hyperspectral and multi-spectral imagers. We will develop and demonstrate a LWIR polarimetric imager under the Phase I contract, and incorporate it into a compact multiband camera capturing simultaneous video in the MWIR and LWIR in Phase II. |

| Title: | Polarimetric Sensor for Air-to-Surface Missile Systems |
| Abstract: | Polarization imaging holds promise for providing significant improvements in contrast and background clutter rejection in a number of target detection and discrimination applications. In several recent development efforts, it has been demonstrated that manmade objects have a significantly stronger polarization signal than natural backgrounds resulting in good contrast that complements the conventionally imaged infrared signature. However, the experimental polarimetric systems which have produced these data sets frequently require long data acquisition times which result in artifacts in the polarization imagery due to platform or target motion, or involve very large hardware packages not appropriate for an EO seeker system. Polaris Sensor Technologies, Inc proposes a comprehensive design trade-off study which considers all existing and emerging polarimetric architectures to determine an optimal design for a seeker imaging polarimeter. Established models will be used to determine the optimal waveband(s) of operation. MWIR, LWIR and MWIR/LWIR bands will be considered. A concept design of the seeker imaging polarimeter will be developed based on the design trade-study output. A Phase I Option would provide a detailed system design including optical, mechanical and electrical designs. |

Unified kε and algebraic stress (EASM) turbulence models, shown to adequately simulate fundamental high-speed jet data sets and now being validated with PIV data sets in a NASA Marshall program focused on baseflows, will be used. Complimentary Large Eddy Simulations (LES) will provide additional turbulence statistics that are not readily/reliably measured. The data will support enhancements to the CRAFT Tech unified k-ε turbulence model. The impact of employing a variable turbulent Prandtl and Schmidt number methodology, based on a two-equation scalar variance framework, will be considered for reacting and non-reacting base flows. The effort will lead to extended validation of enhanced turbulence modeling tools, increased reliability of base drag & heat flux predictions and fills a major gap at the US Army by improving upon base region simulation capabilities required for design of hypersonic interceptors. The program will also conduct initial planning for acquisition of “high-quality” baseflow data in the 12”X12” tunnel at the National Center for Physical Acoustics (NCPA), utilizing non-intrusive diagnostics. |

| Abstract: | A computational investigation of missile interceptor base flows in a supersonic/hypersonic application is proposed. High-fidelity three-dimensional simulations will be conducted using the proprietary framework Rocstar. The computational framework includes a compressible flow solver with advanced LES turbulence models and has flexibility sufficient to investigate a variety of base flow configurations under widely varying conditions. As a feasibility study for Rocstar, in Phase I we propose validated simulations for the flow past the cylindrical blunt afterbody configuration of Herrin and Dutton (1994) at Mach number of 2.5. In the Option period, we will develop a validation matrix, including a variety of geometries, for implementation during Phase II. We will also execute a simulation of the boat-tailed geometry. Professor J. Craig Dutton will serve as technical advisor to IllinoisRocstar on the SBIR project. The overall goal of this work is to develop, validate, and commercialize a numerical tool suitable for design and analysis. The code should accurately predict supersonic and hypersonic base flow characteristics to within ±5%, especially pressure and velocity data. At the conclusion of Phase I and the Option, we will have completed a study assessing Rocstar capabilities, compared two well-known afterbody geometries, and assembled a set of validation cases to direct and extend Rocstar for turbulent base flow. |

| Title: | Metallic Grid Application for Green Ceramic Domes |
| Abstract: | Transparent domes for multimode seeker technology with integrated fine metal grid for EMI shielding are currently being developed. Specific line width and spacing requirements for the embedded metallic grids in the domes significantly limit the available methods for fabrication. A potential approach to producing these structures is by applying a metallic grid pattern to the green dome blank, and then adding a second green layer of the same material over the grid. When the green blank is fired, the metal grid pattern sinters together into a continuous metal pattern at the same time that the ceramic layers are sintering together into a dense ceramic. We propose herein to develop a direct write grid application method, suitable to achieve the electrical requirements for the EMI shielding. The proposed method will overcome the prior issues by providing opportunities for a wide conductor material choice, as well as variable line thickness capability. Our proposed efforts build on prior and current experience with direct write methods that have been, or are being evaluated for this application. Gridded coupons and partial domes will be demonstrated in Phase I. A fully gridded 7” hemispherical dome will be produced by the end of the Phase I Option. |

| Title: | Conformal Metal Grid Patterning for Green Spinel Domes |
| Abstract: | Soft lithography is an inexpensive and fast method for applying micropatterned structures to both flat and nonplanar substrates. TA&T leverages multiple soft lithographic processing steps to pattern co-fireable refractory metal grid on spinel dome windows for electromagnetic interference (EMI) filtering purposes. In addition to the overall curvature of a green ceramic dome, the surface roughness poses difficulties that preclude many other techniques for applying high fidelity features to a surface. The proposed approach overcomes the technical issues by forming the conductive material grid pattern on a transfer film that can be integrated into the ceramic production process. A micromolding technique which infiltrates a photocurable resin formulated with metal loading into channels which define the grid dimensions is developed to pattern on the film. The complete system of inorganics and organics necessary for the gridding and transparent ceramic production is considered for compatibility. The resulting grid is expected to have low sheet resistance for high EMI shielding performance. |

| Abstract: | Presently, there is a pressing need from U.S. Army in developing metal-coated carbon fibers, which will be used as the payload for the Joint Program Manager (JPM) microwave obscuration program because they are excellent attenuators in the microwave region of the electromagnetic spectrum. The metal coatings around carbon fibers are required to be highly conductive, less than 50 nm, and simultaneously can be produced cost-effectively. However, there is not a cost-effective processing method available that is capable of depositing a thin metal coatings less than 50 nm around carbon fibers. Therefore, in this proposed research program, Aegis technology will: (1) Develop and demonstrate a novel nano-coating method for carbon fibers based on one-step exchange-cross-linking- precipitation to generate a highly conductive metal nano-layer (less than 50 nm) around carbon fibers; (2) Identify the underlying technical issues that govern the fabrication and performance of the coating system; and (3) Use this knowledge to design and manufacture such highly conductive metal nano-coatings around carbon fibers that exhibit the extinction coefficient required by Army. The anticipated technological impact of the proposed research program is the development and implementation of a low-cost nanoscale thin-film fabrication concept based on stabilized metal nanoparticles that provide the performance of metal-coated carbon fibers exceeding that with commercially available technology. |

| Title: | Low-Cost Method for Metal Nano-Coating of Anisotropic Fibers |
| Abstract: | Physical Sciences, Inc. (PSI) proposes to demonstrate the low cost fabrication of chopped carbon fibers with a 50 nm thick, continuous copper coating deposited by electroless methods. We will utilize electrospinning to fabricate uniform polyacrylonitrile fibers with a diameter that upon pyrolysis will yield carbon fibers with 2 micron diameter. The polymer fibers will be pyrolyzed under tension to yield straight carbon fibers. These continuous fibers will be chopped to provide lengths of from 3 to 6 mm, for the 2 micron fibers. Because the fibers are straight, they will be relatively easy to disperse. The copper coated anisotropic carbon fibers are expected to have an extinction coefficient exceeding 6 m^2/g at 35 GHz. During the Phase I Option, PSI will fabricate 1 micron diameter, copper coated fibers. The Phase II program will enable diameter, aspect ratio and electrical conductivity tuning and process scale-up to the kg level. Our expertise with electrospinning scale-up to produce 5 km long tows of 3 micron polymer fiber enables a solid baseline production to build upon in Phase II. |

| Title: | Compact and Mobile Biofuels Production System for Forward Sites |
| Abstract: | To support tactical fuel requirements at forward sites, biomass wastes from operations and those locally available need to be converted into viable military fuels. Conventional approaches cannot produce military type fuels using compact and mobile reactors. Through recent efforts, Altex and PSU have identified a novel approach that can achieve the conversion of mixed biomass wastes to a JP-8-type fuel in a compact and mobile platform. Preliminary tests have shown the potential of the concept and the needed components have been integrated on two mobile trailers to allow testing in the field. Under the proposed Phase I project, the concept will be adapted to the Army biomass waste to military fuel application of interest; and the performance and cost benefits of the concept will be determined versus alternative techniques. In support of this assessment effort, a subscale test article will be built and tested. These efforts will show the feasibility of the concept for Army biofuels applications of interest. |

| Title: | Bimodal Standoff Biometric Collection System |
| Abstract: | To address the Army need for standoff capture of multimodal biometrics, Physical Optics Corporation (POC) proposes to develop a new Bimodal Standoff Biometric Collection (BISBIC) system for multimodal high-resolution biometric capture, based on POC''s innovative nonoptical zoom with wide field-of-view (FOV) technology with a ultrasuperpixel array. It is based on POC’s innovative, ultrawide-FOV (90 deg. x 12 deg.) technology with no moving components, volume captures (no orientation requirements) and a superfocal-plane array. BISBIC performs instantaneous electronic zoom on biometrics (iris and face) without restricting the subject’s activities or orientation. BISBIC features wide capture volumes in all orientations with instant, telescopic, high resolution (0.1 mm) at 100 meters, which is unprecedented. The BISBIC package is 12 in. (dia) x 8 in. (long), and <10 lb. In Phase I POC will demonstrate the feasibility of BISBIC by building and testing functional BISBIC components in a laboratory testbed. In Phase II we plan to design, fabricate, and test a fully functional prototype in a realistic environment. |

| Title: | Composit Tracking and Discrimination Module |
| Abstract: | The project objective is to develop a set of mathematically rigorous Composite Tracking and Discrimination Modules (CTDMs) for accurately fusing both kinematic and non- kinematic sensor information to contribute to a consistent Single Integrated Air Picture (SIAP) containing both Tactical Ballistic Missiles (TBMs) and Air Breathing Targets (ABTs). A distributed data fusion architecture is assumed. Local (sensor level) tracks are formed based on measurement-to-track fusion. Multi-sensor system tracks are formed based on track-to-track fusion. The target state vector includes both kinematic and feature states (such as radar cross section and color temperature). Non-linear state estimation methods employed include extended Kalman filtering, a Gaussian sum representation for the target state distribution, and the modified Euler method for approximating the solution to the target state SDE. Data association is formulated as a classical assignment problem. Data association hypotheses are generated using the Munkres algorithm. A graph-theoretic algorithm is used to form cluster tracks partitioning the data association problem into independent subproblems. The bandwidth required to communicate tracking data across the distributed network is reduced by sending pseudo-measurements that capture the information from multiple physical measurements. A Bayesian inference engine performs the target discrimination and classification function. Multi-sensor registration is performed using non-Gaussian methods. |

| Title: | Sensor Geodetic Registration for Tactical Ballistic Missile (TBM) Composite Tracking and Discrimination Capability for Army System of Systems (ASoS) I |
| Abstract: | Critical to the success of distributed sensor fusion for IAMD is the ability of each network sensor to correctly associate sensor measurement and attribute data to tracked objects within the air/missile picture. To achieve this, multi-sensor fusion requires sensor registration techniques that ensure network sensor are sufficiently synchronized and spatially aligned. The goal of sensor registration is to reduce the range of uncertainty inherent in a given single radar by considering the "cross correlations" that exist between the data on common tracks observed by network sensors. Our approach to sensor registration is to provide geodetically aligned sensor data within a component based distributed architecture using methods that act on geodetic calibration tracks and other fiducial data points common to the distributed sensors to produce location and orientation bias estimates at each sensor. The distributed architecture allows each sensor to compute local biases and apply the computed “offsets” prior to distribution of track data to the tracking network. Sensor registration using simultaneous observation of selected common tracks and fiducial points among distributed sensors has the potential to compute a local sensor registration solution by averaging out the uncorrelated random bias errors that will be present within the ensemble of networked sensors. |

| Title: | DC Power Supply Technology for Air Cooled Systems |
| Abstract: | Magnetic components are the greatest source of design problems and failure in switching power supplies. New component integration technologies and higher performance materials sets are needed to develop high efficiency, high power density, fast transient response DC-to-DC converters that support high peak power, and high average power loads for next-generation air-cooled active array radar systems. Performance limitations of state-of-the-art circuit modules are primarily rooted in discrete component assemblies and the use of sub-standard materials sets in the construction of magnetic and passive components, as well as the electrical interconnects. Composite Ceramic Technologies, LLC, Austin, TX, (the “Company”) will overcome these limitations using its proprietary deposition technology to achieve improved performance in laminated magnetic components and integrate “ideal” materials sets into a monolithic electronic circuit module. Fully integrated DC/DC converter modules constructed using these patented process methodologies will deliver optimal power efficiencies, power densities, and transient response. The unique broad-based solutions enabled by this program serve multiple interests in the Tri-Service community and have the potential to extend the field life and improve the battlefield readiness of new and legacy radar systems. This submission promises to deliver substantially higher value than competing proposals that simple address circuit board or control topologies. |

The custom made three dimensional magnetic design will allow us to increase the switching frequency to >500kHz, while maintaining >92% efficiency at 12V output. The power devices and magnetic will be utilizing the high temperature common package with Direct Bond Copper, substrate for better heat transfer. The power converter will have integrated diagnostics and operation status reporting. The base plate will be integrated with the cooling fins to optimize the heat rejection. The proposed design is cost effective for low volume production and it is designed for dual use of DOD and heavy duty hybrid commercial vehicles and telecom. US Hybrid similar design dc-dc converts has passed the NEBS, telecommunications qualification, which includes the EMI/EMC, shock, vibration and drop test as well as thermal cycling.

| Abstract: | Leveraging on our extensive experience on laser projection technology, AGILTRON proposes to realize a new class of see-through type of Head Mounted Display (HMD) with wide field of view (WFOV) and dynamic foveal vision ability, targeted for integrating with enhanced vision systems for night and daytime dismounted infantry combat operations with a secondary function of providing command and control information and external imagery from weapon sights or other platforms. The proposed HMD is very lightweight, compact, easy to mount on any standard helmets, and is based on commercial components. Furthermore, our designs offer advantageous attributes of high speed, low cost, simple design, and withstand severe environmental conditions. The feasibilities of the proposed laser projection technology have been successfully demonstrated. In this Phase I program, the image processing algorithm will be optimized and a functional prototype of the proposed foveal vision HMD will be developed and demonstrated. |

| Abstract: | This Navy Small Business Innovation Research Phase I project will be used to fabricate, measure, and test a novel optical design for use in a new type of ultra high-definition (UHD) head mounted virtual reality display (HMD) that can incorporate a UHD AOI feature without moving parts or extra displays. DTI has demonstrated a large screen (UHD) projection technology that uses a rapidly scanned microdisplay to produce images possessing much more resolution than the microdisplay itself. It accomplishes this by illuminating different sub regions of each pixel during each scan, producing an image made up of the sub regions instead of the pixels. During this project DTI will investigate and bench test a novel illumination and optical system will that can produce arrays of sub- pixel sized illumination spots on off the shelf microdisplays in a very compact space. This system will then be operated in conjunction with an eye tracker to demonstrate a movable high resolution foveal insert in a lower resolution field on an off the shelf microdisplay. DTI will also investigate adaptation of the system to an exiting head mounted system. |

| Title: | Dual Reflection Waveguide Ultra-wide View Display |
| Abstract: | The Navy has long had a need for a wide field of view Head Mounted Display to provide situation awareness. Taking into account eye position, the image at the HMD should be presented with highest resolution at the center and much less but still acceptable resolution on peripheries. Intelligent Optical Systems proposes to develop a Dual Reflection Waveguide Ultra-wide view display that will provide situation awareness, allow 120 degree peripheral view, and provide a maximal resolution direct view without any moving mechanical parts. The novel optical system is based on dual use of waveguide surfaces for peripheral and direct view information. IOS has successfully completed a series of government projects related to the proposed technology. The diverse experience of the technical staff in the areas of stereovision displays, optical waveguides, image processing, and high performance video processing will contribute to the successful completion of this project. In Phase I, we will perform ray tracing for complete optical design and develop prototype software to correct for wide view image presentation in both see-through systems and non-see-through systems. In Phase II, we will fabricate a prototype system with wide view display and higher than human resolution limits in the foveation area. |

| Title: | Augmented Reality Gaze-Under-control Super-resolution Head Mounted Display |
| Abstract: | To address the USMC need for a dynamic foveal vision display, which increases situational awareness of dismounted Marines, Physical Optics Corporation (POC) proposes to develop a new Augmented Reality Gaze-Under-control Super-resolution Head-Mounted Display (ARGUS HMD). The ARGUS-HMD is based on optical-electronic- software implementation of foveal vision that creates an illusion of a panoramic high- resolution image on a see-through display from data stored in a PDA. This unique performance is achieved due to innovative system design and optimized image rasterization software integrated with eye-safe eye trackers. The image with a high resolution raster is rendered within the foveal area and with gradually lower resolution in the peripheral area. The rasterized image is projected onto a see-through ballistic-impact face shield that allows the Marine to see augmented high-resolution data such as detailed 3D maps, floor plans, or instruction text while looking through this image to a real ambient scene. In Phase I POC will demonstrate the feasibility of the ARGUS-HMD system and identify potential advantages and limitations of the proposed approach. In Phase II POC plans to develop a fully operating prototype implemented on a real HMD, which will be ready for testing by Marines in a field environment. |

| Title: | Dynamic Foveal Vision Display |
| Abstract: | Head Mounted Displays (HMDs) currently lag behind both sensors and information systems in their limited ability to provide the warfighter information. Current sensors at greater than mega-pixle levels are common, and display systems typically operate in excess of several megapixels. Microdisplays, on the other hand, are still limited to less than a megapixel in most cases. The ability to provide warfighters more digital information will move the efforts to integrate the dismounted marine or rifleman into the digital battle space forward. The drive to increase the warfighter’s situational awareness is a key factor in increasing that warfighter’s combat multiplier by enabling greater mobility, lethality, and survivability. Trex Enterprises has devised a novel approach to providing a high resolution, narrow field of view foveal region coupled with a lower resolution wide field of view peripheral display. The approach outlined has numerous advantages over conventional approaches, including zero moving parts and the ability to provide the full desired capability using commercially available microdisplays of nominal resolution (800x600 pixels). The use of existing microdisplays has numerous benefits, including reduced cost as well as reduced required bandwidth and power (versus larger, custom displays). |

| Abstract: | The objective of this SBIR Phase I project is to produce a tough protective nanocomposite ceramic lining for machine gun barrels to reduce weapon system acquisition costs through service life extension, reduction in parts consumption & failure rates, reduction in weapon weight, reduced corrosion, and reduction in barrel heat load. We postulates that incorporation of a ceramic radiant barrier lining will send more heat out the nozzle with numerous benefits. Advanced Materials and Processes has identified candidate materials and processing techniques that will produce integral tough nanocomposite ceramic linings for outstanding barrel life. The process is applicable to machine gun barrels of any size. AMP will prepare two prototype ceramic gun barrel coatings and test for hardness, crack resistance, adhesion, thermal conductivity, and live firing. FN Manufacturing (FNMI) is collaborating on this project. FNMI will provide barrel tubes and technical support in Phase I. They will also provide 2000 round live fire testing/evaluation of two prototype coated gun barrels in Phase I and 10000 round live fire testing/evaluation of one prototype in Phase I Option. FNMI believes that the proposed ceramic liners are worth investigating because if successful they will enable a quick implementation and practical way to production. |

| Title: | Thermally Stable Machine Gun Barrel |
| Abstract: | The proposed project seeks to take advantage of the success of an on-going Air Force Phase II SBIR and leverage the lesson’s learned with medium calibre barrel to apply the new technology to small caliber machine gun barrels. In the previous Phase I and on-going Phase II projects, the feasibility of producing a fully dense, non-micro-cracked Nanostructured cobalt–refractory metal alloy with co-deposited hard ceramic particles was demonstrated. The Nanostructured coating was found to have wear resistance equal to that of hard chrome coatings, but did not suffer from the same micro-cracked structure that chrome possesses, even after thermal cycling to 1832°F. Laser pulse testing simulating the heat input experienced in a 25mm medium caliber gun barrel (M242 with M919 propellant) showed no significant damage or microcracking as seen in hard chrome coatings. The absence of a micro-cracked structure in the Nanostructured coating is expected to result in increased performance over the current hard chrome coatings in the gun-barrel bore due to the lack of a pathway for the hot-erosion combustion gases to attack the base-metal, thus leading to a longer lifetime. Additional benefits of the Nanostructured coating relative to hard chrome include: faster deposition rates, lower power consumption during processing, and elimination of the health risks associated with hexavalent chromium (Cr6+). The specific objectives of the proposed program are to: (1) develop the tooling needed to apply the Nanostructured composite coating to the inner bores of small caliber (5.56mm/M249 or 7.62mm/M240) machine gun barrels (the current on-going Phase II SBIR is specifically investigating 20mm barrels), (2) perform actual field testing to demonstrate and validate the technology, and (3) define all critical technical parameters in a thorough process specification to allow the technology to proceed to facility demonstration/validation activities. Based on the results of these tests a full Implementation Assessment will be performed to determine whether performance and cost will make this a cost-effective solution for the various small caliber platforms used by the Navy. |

| Abstract: | QuesTek Innovations LLC, a leader in the field of computational materials design, proposes to develop a new liner material and manufacturing processes, enabling a fully- lined machine gun barrel system to withstand the extreme conditions of sustained fire. Currently, warfighters must typically carry a minimum of two gun barrels into action due to the poor thermal capability of current machine gun barrels. Thermal breakdown of gun barrels during sustained fire is caused by many mechanisms, but is largely due to degradation of the gun barrel bore during exposure to the high-velocity hot propellant gases. Unprotected steel barrels quickly fail due to the combined effects of oxidation, carburization and high temperature. Current options to protect the bore only protect a portion of the barrel length due to manufacturing limitations or perform poorly under the extreme conditions of sustained fire. QuesTek’s program will involve Marine stakeholders and Army materials experts familiar with gun technologies, ensuring that the solution meets manufacturing, cost and other objectives. The Phase I Base program will demonstrate the capability of Co-alloys for thermally stable machine gun barrels by manufacturing and testing monolithic Co-alloy barrels. Alloys optimized for liner-sleeve barrel manufacturing at reasonable cost will be designed in the Option. |

| Title: | Explosively Clad Liners for Extended Barrel Life |
| Abstract: | Gun barrel life is limited by erosion, heat and wear. Barrel steels and failure mechanisms have changed little since the end of World War II. Performance requirements of modern gun systems continue toward higher velocities, greater rates of fire and longer projectile ranges result in greater in-bore pressures, heat and erosion. A critical need exists to increase barrel life, and therefore, sustainability. Coatings are of limited use for over- heating problems. Thicker liners have been tried, but are problematic when they are not bonded to the barrel. Using a proprietary explosive, TPL developed a unique explosive cladding process to metallurgically bond high-temperature, corrosion-resistant liners to steel or lighter weight barrel materials. TPL has demonstrated that solid liners, thicker than coatings and metallurgically bonded to the barrel, extend barrel life by 5-7 times. TPL will adapt this technology to small caliber machine gun barrels. Phase I Objectives include developing bonding parameters, verifying the metallurgical bond and producing test pieces. Barrel blanks will be clad and tested. Option tasks include cladding, machining and test firing a prototype Commercial support is lined up to help develop and market this technology. TPL has experience in barrel cladding and a site to perform the explosive work. |

| Abstract: | The objective of this Phase I SBIR program is to develop innovative lightweight, ballistic resistant ceramic nanocomposite armor plates that may be used in place of enhanced small arms protective inserts (E-SAPI) within Interceptor Body Armor (IBA) systems. The proposed lightweight ceramic composite inserts will integrate NanoSonic’s pioneering ceramic copolymer materials with shear thickening Kevlar® and Dyneema® fiber reinforced backings to provide protective armor inserts that weigh less than 4.00 lbs, provide enhanced soldier maneuverability and occupy less volume within interceptor vests than E-SAPI plates. This effort will build from NanoSonic’s independently validated hybrid nanocomposite armor materials that have demonstrated 1) V50 values > 4,000 ft/s to 3/8” A36 steel plates (MIL-STD-662F), 2) multiple shot protection from 0.50 cal rounds and 3) exceptional flame resistance (time to ignition > 300 seconds and low toxicity smoke). Through these efforts, researchers will develop an array of lightweight armor inserts capable of fragmenting and catching 5.56 mm, 7.62 mm and AP rounds. The potential technological advantages of NanoSonic’s lightweight, highly flexible body armor plates includes their ability to protect soldiers from multiple threats (ballistic, fragment and flame), long term environmental durability, tailorable weight and ease of integration within commonly employed composite manufacturing techniques. |

| Abstract: | The Navy is interested in developing a high performance analog fiber optics transmitter for high dynamic range RF applications. The interest in fiber optics is to eliminate the current heavy, difficult to install, hard to maintain, Electro Magnetic Interference (EMI) susceptible copper based RF links such as rigid coax or specifically tuned cables with light, flexible, high bandwidth, EMI immune optical fiber cables. Princeton Optronics has developed high performance analog transmitters in the past meeting most of the desired specifications of this SBIR and has developed a mechanical platform which provide the ability for the free space optically coupled components to maintain their optical coupling integrity over Navy temperature range and can withstand the desired shock and vibration. We would use that platform and use the newly available components like high performance lasers and smaller modulators to achieve the desired performance and size for the transmitter. In phase I, we would do the simulations as well as coupling experiments with the laser and the modulator and make a design which would meet all the requirements of this SBIR. In phase II, we would build the transmitter and test it extensively. |

| Title: | Portable Non-Contact Heating and Soldering Tool |
| Abstract: | Currently available soldering and heat gun systems have several significant deficiencies that can result in lower quality repairs and higher maintenance costs. The existing soldering irons naturally lead to cross-contamination between leaded and lead-free solders, resulting in degraded solder joints. The existing heat guns require bulky accessories and/or external electric power, making them unwieldy and causing the repair process to be slower and more difficult. The current battery operated systems are more portable, but they have less heating capability and short operating times. In response to these needs, Accurate Automation Corporation is developing a unique tool that utilizes infrared energy to perform both non-contact soldering and heat shrinking. This innovative product will provide for lower maintenance costs and higher quality repairs by offering improved portability, longer operating time, and multifunctional capability while preventing solder cross contamination. |

| Title: | A Novel Non-Contact Soldering Iron/Heat Gun for Electronics Fabrication |
| Abstract: | While contact-based soldering irons have been sufficient for the Navy’s needs for a number of years, the need to support new lead-free and older leaded solders is impossible with the current soldering irons without the risk of cross-contamination. In addition, the combination of the soldering iron and heat gun into one device would reduce costs and operational constraints. Creare’s innovation is a novel Non-Contact Soldering Iron (NCSI) that can solder electrical connections and also function as a heat gun. The total weight of our battery-powered NCSI is approximately 2.5 lb and is similar to that of a common household flashlight. We have used low cost components such that the final cost of our NCSI will be approximately $95. Thus, our solution is flexible, lightweight, affordable, and portable. Our NCSI combines the benefits of non-contact, radiation-based soldering with the convenience of a hand-held, battery-powered device. In Phase I, we will establish the foundation for further development and technology transfer at the completion of Phase II. Creare will work closely with the U.S. Navy and the program offices during Phases I and II to ensure that we are responsive to the needs of DoD maintenance and flight-line efforts. |

| Abstract: | To address the Navy need for a heat gun/soldering iron compatible with leaded and lead- free solders without risk of cross-contamination, and with all approved heat shrink and solder sleeves, for use in a Navy flightline maintenance environment, Physical Optics Corporation (POC) proposes to develop a new MultiFunctional Laser Heat Source (MFLaHS) based on a near-infrared laser diode, beam-shaping optics, laser driver electronics, and a rechargeable power source. The use of a laser ensures compatibility with all types of solder without risk of cross-contamination. The novel MFLaHS design is compact, lightweight, portable, stand-alone, and qualified for flight-line maintenance environments, with a long operating time. Its innovative beam-shaping optics provides optimal working distance with absolute safety for the surrounding materials and staff. These features directly address the PMA-261 and H-53 Helicopters requirements. In Phase I, POC will demonstrate the feasibility of MFLaHS by developing and demonstrating a functional prototype of technology readiness level (TRL)-4. In Phase II, POC plans to develop a TRL-7 prototype and conduct testing to demonstrate the operation of MFLaHS technology in a relevant environment. |

| Title: | Innovative Approaches for Improving Progressive Damage Modeling and Structural Life Prediction of Airframes |
| Abstract: | An automatic software tool for 3D fatigue crack growth prognosis of structural systems under realistic complex loading will be developed by integrating a unified growth model with a mesh independent extended finite element toolkit in ABAQUS. The tool will be able to model arbitrary non-planer crack growth over multiple growth regimes with an arbitrary stress ratio without user intervention or remeshing. GEM has established the business partnership with SIMULIA (ABAQUS) and secured commitments for technical support from Bell Helicopter, who will provide supporting data, information, and expertise. In addition, our consultant, Professor Liu from Clarkson University, will aid in fatigue model development, and provide existing fatigue damage model for the toolkit integration. The multi-faceted feasibility study consists of developing an add-on ABAQUS toolkit that will enable the following: 1) a new unified fatigue crack growth modeling technique that captures the stress ratio effects under both uniaxial and multiaxial load; 2) arbitrary insertion of multiple 3D cracks that are independent of the finite element mesh; 3) characterization of a growing crack using the level set and fast marching method; and 4) demonstration of the applicability and computational efficiency of the developed toolkit at component and structural level. |

| Title: | Innovative Approaches for Improving Progressive Damage Modeling and Structural Life Prediction of Airframes |
| Abstract: | Current damage tolerance analysis methods are often only applicable over a short growth regime and require extensive calibration with test data. A novel methodology proposed by Vasudevan et al, based on a two-parameter method known as the unified crack growth model, improves these shortcomings. The NextGen team seeks to integrate the unified crack growth model with the AeroLabTM advanced CAE software framework to create a robust damage tolerance analysis module. The finite element capabilities of the AeroLabTM system will allow the stress intensity factors for the crack front to be calculated easily for complex crack geometries and complex loadings. The benefit to the user is the ease of creating robust real world solutions that converge with minimal effort within an integrated CAE software environment. |

| Title: | Innovative Approaches for Improving Progressive Damage Modeling and Structural Life Prediction of Airframes |
| Abstract: | Technical Data Analysis, Inc. (TDA) proposes to create a functional link between a finite element solver and UNIGROW, a fatigue and fracture mechanics program implementing the two-parameter approach to fracture mechanics developed by TDA and Dr. Grzegorz Glinka of the University of Waterloo, with support from ONR. This link will enhance the capability of both programs by providing a means of analysis automation for fatigue crack growth. Currently, fracture mechanics analysis relies on simplified models based on empirical rules to determine stress intensity factors. However, the sometimes poor correlation of these models to real structure leads to a large amount of uncertainty in fatigue crack growth calculations. The proposed product will allow any real structure to be analyzed for crack growth using the well established weight function methodology. After creating a component finite element model, a simple linear static analysis will determine stress distributions on any number of user-identified or automatically-identified crack planes. Those stress results will be linked to UNIGROW, which will utilize the weight function approach to determine accurate stress intensity factors and fatigue crack propagation. The end result will be enhanced fracture mechanics analysis capability, leading to safer, more efficient designs. |

| Title: | Beam Director/Expander for High Energy Laser Applications |
| Abstract: | The overall goal of this project is to design, fabricate, and test a compact, low power, aircraft-mounted Beam Director/Expander (BD/E) for High Energy Laser (HEL) Applications. Examples of HEL applications include: (1) directed energy weapons from air- and space-borne sources, and (2) countermeasures for surface-to-air missiles aimed at aircraft. Both applications require high bandwidth and high accuracy to reject structural disturbances (jitter) from the base aircraft and to enable rapid target acquisition and tracking. Tactical beam directors for these applications need to: handle laser power up to 300 kW, have optical throughput greater than 90%, work with wavelengths between 1.0 micron and 1.1 micron, have residual wavefront error less than lambda/8 at 1.06 micron, have residual jitter less than 2 microrad, have slew rates exceeding 2 rad/sec, be capable of slew accelerations greater than 2 rad/sec2, take up less than 0.2 cubic meters, and have mass less than 50 kg. Our proposed Beam Director/Expander combines a unique, optical design; advanced mirror materials; novel actuator technology; and proven gimbal and high-speed control system electronics. During Phase I, we will demonstrate the feasibility of our approach. During Phase II, we will fabricate and test a bench-top BD/E. |

| Title: | Tactical Beam Director for Airborne High Energy Laser Applications |
| Abstract: | Most gimbal systems are designed for maximum stiffness and lowest mass. Gimbal stiffness is generally a principal requirement because the control bandwidth and pointing capability are directly related to the stiffness. Typically, the need to satisfy mass and stiffness requirements forces a compromise between the geometry and the materials. To date, design and development of high performance gimbals have been based on increasing the stiffness to the greatest extent possible and then controlling the gimbal with classical control techniques to the highest bandwidth possible. An alternative approach is to utilize flexible body control techniques with a relatively soft gimbal to enable pointing control beyond its first structural mode. Doing so would enable lightweight, low cost gimbals to be incorporated into airborne platforms. This effort will develop the advanced control techniques needed to effect precision pointing of a lightweight beam director. |

| Abstract: | The objective of this Phase I effort is to develop a new means of detecting undersea targets in the reverberation return as well as in the forward scatter zone. Previous tests regarding Forward Scatter Detection had not been able to establish acceptable False Alarm Rates (FAR), at a sufficiently high Probability of Detection (PD) to warrant further development. However, newer developments using an array of co-located pressure and pressure gradient (i.e. velocity) sensors, showed potential as an undersea target detection mechanism. The proposed effort will follow up on these tests, both from a theoretical and practical measurement sense, to define sonobuoys which are capable of this new detection technique. Potential applications will be to the navy, as well as to homeland security for harbor defense and enemy diver detection. |

| Abstract: | Existing Air ASW multistatic sonar search systems do not fully exploit all of the scattering information available in the acoustic field. This project seeks to further demonstrate that multistatic target echoes affect the acoustic field in a manner that allows one to differentiate target from non-target energy by using vector sensor quantities. During Phase I, we will examine target features using data from new vector sensor target scattering experiments that extends the work of previous research. We will use a signal subspace approach to develop new vector sensor algorithms that improve upon intensity based methods for the detection of forward scatter targets. In addition to the forward scatter cross range intensity phase anomaly feature, we will examine the potential of extracting cross range features in other geometries. During Phase I, we will also reanalyze existing data sets from experiments that contain vector sensors and target scattering to show improved detection and classification performance. In this way, Signal Systems Corporation will demonstrate the proof of concept of new discrimination clues in scattering regimes that have high target strength and a current paucity of physics based features. |

| Title: | Environmentally-Robust Matrices for SiC Composites |
| Abstract: | Ceramic Matrix Composites (CMCs) are emerging as mission-critical materials for a broad range of defense applications and among them, their utility for next-generation aero- turbine components are currently being pursued. SiC-based CMCs are leading candidates for this application due to their high strength, low density, and superior toughness at elevated temperatures. In this Phase I project, a new matrix material is being proposed based on the concerns for the environmental durability of SiC under turbine service conditions. At elevated temperatures, degradation of SiC CMCs due to presence of oxidation, moisture, salt, and CMAS is well known. While barrier coatings deposited on exterior surfaces can mitigate the problem to a certain extent, it is becoming apparent that more robust ceramic matrices need to be developed using low-cost approaches. In this regard, recent advances with preceramic polymer-derived matrices are noteworthy. This Phase I project addresses a unique and innovative matrix material using CMC-compatible processing technique to enhance the durability of SiC CMCs in such harsh environments. Fabrication of CMC samples, exposure tests, and mechanical testing comprise the major tasks in this project. Partnership with a prime defense contractor and manufacturer of CMCs is established for this investigation to provide technical guidance. |

| Abstract: | Kion Defense Technologies, Inc. (KDT) has teamed with a composite manufacturer to develop and demonstrate the effectiveness of a new, integrated matrix system for SiC- based composites for use up to 1300oC (2400oF). KDT will employ its patented polysilazane resin manufacturing process to incorporate B and Zr or Ti heteroatoms into its ceramic precursor (CERASET) resins to produce SiZrBCN or SiTiBCN, ceramics, respectively. These resins will be suitable for CMC matrix PIP processing and fully compatible with the composite matrix precursor for infiltration, pyrolysis, and resultant coefficient of thermal expansion (CTE). The resulting composite microstructure will offer oxidation and corrosion protection as a result of the layered matrix structure. Furthermore, the proposed innovation is an improvement on the already tested and approved composite system, thus will require less testing and qualification than a new materials system and process that starts entirely from scratch. |

| Abstract: | MATECH GSM (MG) proposes demonstrating a low-cost and enhanced-environment- and erosion-resistant CMC material system, ASGMAC (SiC/SiC(N,Me)), by optimizing MG’s low-cycle PIP matrix densification method and by adopting modified (and/or functionally graded) polymer pre-cursor derived matrices for higher erosion and corrosion resistance at elevated temperatures up to ~2700F. The modified and functionally graded matrices are to be functioned for mitigating the current issues of the EBC onto the Si-based CMC substrates, such as poor impact resistance and unstable microstructures of the CMC surface over-coating. MG has successfully demonstrated 5-cycle PIP densifications of 2D / 3D architecture CMC panels using a pre-ceramic Si-based polymer and also has successfully synthesized a variety of Zr- (or Hf-) based ultra-high temperature pre- ceramic polymers for UHT ceramic fibers and matrices. The CMC community is well aware of several issues having to do with the Si-based material systems; one of those is a necessity for significant improvement in moisture and salt-fog corrosion resistance. MG’s objectives are: 1) Tailor the matrix composition rather than using Si-based but other refractory-based ceramic matrix formation, 2) Add second refractory or rare-earth oxide forming element in the current Si-based SiC or SiNC polymer that enhances moisture / salt- fog environmental resistance. |

| Title: | Chemically Modified SiC/SiC for In Situ Growth of Nonvolatile, Environmental Barrier Scale |
| Abstract: | For significant advancements to occur in the implementation of ceramic matrix composites (CMCs) in aeroengine airfoil applications, silicon carbide (SiC) ceramic matrix that forms corrosion resistant scale is needed for the combustion environment. Particularly troublesome is the accelerated surface oxidation and recession that proceeds due to reaction of the native silica scale with steam in the high-temperature turbine environment. As opposed to the more convention application of environmental barrier coatings (EBC) by plasma spray to meet this challenge, the proposed effort will develop an steam-resistant matrix material for use in SiC/SiC CMCs. More specifically, chemically modified SiC-matrix CMC panels will be fabricated by PIP processing using rare earth-doped polymer precursors. Evaluation of the resulting CMCs will proceed by measuring their oxidation resistance under aggressive, accelerated aging conditions (steam + O2 at high temperatures) that simulate harsh aeroturbine environment. A wide variety of materials property testing will be performed to measure the mechanical effects on the effect of doping the matrix both before and after aging of specimens. |

| Abstract: | High performance military aircraft require reliable measurement of critical loads on control surfaces during maneuvering and dynamic events such as wing buffet. Innovative Dynamics proposes to investigate a distributed sensor network to continuously monitor the structural integrity of control surfaces especially when in buffeting or flutter situations. Phase I will design a Buffet Load Measurement System Architecture for application to the JSF control surfaces. This will include the development of patch sensors and electronics for making vibration load measurements including the collection, transmission, and storage of sensor time and feature data. The end goal is the development of a structural diagnostic tool that will integrate with the on-board aircraft HUMS box and display post flight buffet load data along with other key aircraft parameters. This will allow users to determine exactly when and where flutter conditions occur during the flight profile. Phase II will develop the system hardware network for demonstration on an actual control surface in a wind tunnel or vibration table demonstration. Phase III will integrate sensors into manufactured parts using direct write processes. Successful demonstration of the system will lead to development of a HUMS based diagnostic tool for monitoring of critical surfaces on high performance aircraft. |

| Abstract: | Current-art systems cannot meet the requirements for Predictive Health Maintenance tracking of buffet stress/strain caused by disrupted overwing vortices on aircraft control surfaces: high sample rates, effectively zero data loss, and zero-to-minimal weight, wiring, or maintenance requirements. International Electronic Machines Corporation (IEM), a leader in smart sensor technology solutions for transportation safety, will create the Buffet Load Accurate Measurement System (BLAMS) with the support and endorsement of F-35 prime contractor Lockheed-Martin and assistance from Albany Nanotechnology. BLAMS will offer a wireless, non-interfering, high-data-rate, high-sample-rate system for tracking buffet loads across multiple points on an aircraft’s structure while having extremely low SWAP demands and low cost. BLAMS will be composed of simple, self- contained rugged sensor nodes which may be inserted nearly anywhere, affixed with any reasonable method, and store all flight data onboard until interrogated remotely by a system which can process the data locally or interface with other third-party systems (thus preventing any interference with other systems). Requiring virtually no maintenance, incorporating UID capability, adding virtually no weight, and lasting for the lifetime of the target components, BLAMS will make accurate, reliable PHM possible for JSF/F-35 and other aircraft applications, improving safety while significantly reducing maintenance costs. |

| Title: | Control Surface Buffet Load Measurement |
| Abstract: | Structural monitoring of Navy aircraft is of critical importance as the fleet ages. One critical area includes the control surfaces, which are subject to intense, dynamic buffet loading which can lead to structural cracking. The highly transient nature of buffet loading makes it difficult to measure using conventional sensors. We propose to solve this problem by combining a network of time-synchronized wireless load sensors with integrated microelectronics for static and dynamic loads sensing, data recording, communications, and energy harvesting. Our proposed sensors possess major advantages, including: sealed stainless packaging, full calibration prior to installation, rapid installation, and locations which enable a full computation of control surface forces and moments. Embedded firmware at each node will detect when buffet loads occur, and each wireless sensor node will automatically increase its sampling rate for high speed data recording. Data during normal aircraft maneuvers shall also be recorded, at a reduced sample rate. Time stamped, synchronized data will be stored in non-volatile memory and may be downloaded wirelessly at high rates upon receipt of a secure command. The embedded firmware also uses micro-power sleep modes whenever appropriate to enable powering by vibration energy harvesting, which will eliminate the need for battery maintenance. |

| Title: | Control Surface Buffet Load Measurement |
| Abstract: | High performance aircraft experience repeated loads that can vary greatly both in frequency and amplitude depending on such factors as flight condition, maneuvering, and aeroelastic characteristics. Loads are monitored throughout the lifetime of military aircraft and used to estimate remaining structural life. Current airframe sensors are unsuitable for measuring unsteady aerodynamic buffet loads, which can be of significant amplitude and occur at frequencies that excite the aeroelastic dynamics, dramatically decreasing fatigue life. Systems Technology, Inc. and Moog, Inc. propose the Actuator Load Computing System (ALCS), an elegant and logistically attractive solution to this problem that employs onboard flight control actuators as load sensors capable of measuring both high frequency and quasi-steady loads. Since actuators directly measure the forces exerted on a control surface, these loads can be used as a robust reference gauge for what is occurring at the wing or tail surface as a whole. ALCS will leverage a novel frequency response identification technique, Narrowband Signature (NBS), which has proven to be successful with very short duration inputs. Since actuators are employed with all of the control surfaces, ALCS immediately extends itself for use with wings, vertical tails, and horizontal tails without the need for additional hardware. |

| Title: | Advanced Canopy and Window Materials for Improved Helicopter and Aircrew Survivability |
| Abstract: | Radio systems play an increasing role in our military and civilian infrastructure, and many of these systems are vulnerable to accidental and malevolent electromagnetic attack. Malevolent EMI attacks on aircraft are not a new threat, and will probably increase in our society due to wide spread availability of electronic hardware and the increasing use of wireless devices. Protection from laser threats has become increasingly important due to the availability of laser sources (continuous and pulsed) over a broad range of wavelengths. This is particularly the case where table top femtosecond laser pulses (~50femtoseconds) with peak powers reaching the Terawatt scale are commercially available in the visible and near infrared. The military uses many laser systems (e.g., training devices, range finders, target designators, communications devices) that emit potentially eye damaging radiation. Because equipment and personnel risk exposure to these threats, a growing need exists for EMI protection of electrical equipment and eye protection at a variety of wavelengths for both CW and pulsed laser sources. Improving the resistance of helicopter canopies and windows to threats from both radio frequency energy and laser effects while maintaining or improving system functionality can protect equipment and personnel. The objective of this proposal is to develop transparent metallo- dielectric multilayer stacks that functions both as an EMI and a laser eye protection coating. We will design and construct multilayer stacks that provide a high transparency window in the visible spectrum but block both UV and IR light. The coating will have sufficient conductivity to offer EMI control and sufficient optical density to protect the eye from damage by laser radiation in these two spectral regions. As part of the Phase I effort we will build and test these stacks on both rigid and flexible substrates in order to provide a wide variety of protection applications. The Phase I work will also produce a technology development and demonstrate plan for the proposed solution that will be executed in Phase II. |

Eikos proposes the use of new processes, structures, and materials based on low cost coating technology that exploits inherent advantages of carbon nanotube (CNT) transparent conductive coatings to reduce absorb EMI and reflect specific laser energy. Aircraft windows and canopies will be laminated from several plies of CNT coated sheets on polycarbonate so that the CNT provides EMI shielding, as well as ballistics protection. Some of the plies will also contain a mesostructured coating to reject laser light at specific wavelengths. The use of CNT allows this structure to be durable during manufacturing and use due to the unique open structure of the CNT. Furthermore, electrical and optical properties of these layers are tunable to address a wide range of EMI and laser threats. Eikos is partnered with a major air framer and a major canopy manufacturer to assist with the development of application needs and to provide testing. |

| Abstract: | Since the inception of radar over 50 years ago, development of battlefield detection and sensing methods has increased dramatically. All methods of detection and sensing that transmit, distribute, or utilize electrical energy can be sources of EMI. Of these sources of EMI, radio frequency energy can cause significant disruption to the operation and performance of aircraft avionics and pose a potential threat to aircrews of the affected aircraft due to exposure through the aircraft canopy. Another device, the low power laser, also poses an exposure danger. The laser can be targeted at the aircrew through the canopy and be used as a weapon by reducing the vision of the person(s) the laser is directed at. United Protective Technologies (UPT) will address these considerations by using a wealth of experience and a company history of laminate based protection of military windows. UPT will seek to incorporate a cost effective, multiple airframe solution capable of reducing or eliminating the threats posed by EMI and laser interference while maintaining the desired optical properties. UPT currently produces a sacrificial windscreen laminate for erosion protection and has obtained airworthiness on multiple airframes. |

| Title: | High Power Pump Couplers for High Energy Fiber Lasers |
| Abstract: | We propose to develop a novel pump energy coupler for high power fiber lasers. The overall goal of this program is to deliver a multi-kilowatt fiber laser system based on the high efficiency coupling technique. High power diode power injection into the inner cladding of active fibers has been a bottleneck for multi-kilowatt fiber lasers. The new coupler will be compatible with any pumping wavelength. The advantages of the new technique will include high wall-plug pump efficiency, brightness preservation, distributed pump injection and good heat dissipation. This proposed project is a moderate risk and high reward effort. The risk is moderate because detailed demonstration of the concept must be made although the theoretical study and preliminary laboratory research have set in place a significant foundation for the proposed effort. The reward is high because the success of the program will eliminate a major obstacle in current fiber laser development. The enabling technology will also benefit other diode pumped solid-state lasers, and provide couplers for researchers to develop new fiber lasers. |

| Title: | High Power Pump Couplers for High Energy Fiber Lasers |
| Abstract: | Realization of fiber lasers with output power in the multi-kW range critically depends on the development of high power fiber components. This proposal specifically addresses the design, development and manufacture of new, all-fiber pump couplers using large- core, single-mode Chirally-Coupled Core (CCC) fiber, capable of operating at pump powers as high as 2kW or more. To improve the performance of pump combiners, we are proposing a new approach developed by AGT Laser (formerly FG2 Tech) using a specially designed coupling piece between the pump fibers and the signal DCF. This approach is a side-coupler design that allows for the DCF to remain continuous inside the coupler. This novel design eliminates the problem of matching cores when splicing the coupler signal fiber to an additional DCF, as is required in the end-pumping approach. This approach is fundamentally independent of the particular type of DCF and can therefore allow the use of a novel and demonstrated highly-scalable mode area, single-mode optical fiber that can incorporate polarization maintaining performance. |

| Title: | Improved High-Power Pump Couplers |
| Abstract: | Recent advances in fiber lasers have shown their potential for power scaling to Directed Energy (DE) levels. Many of the high-power, cladding-pumped, large-mode-area (LMA) fiber systems demonstrated in the laboratory have employed free-space optics to couple the diode-laser pump power into the pump cladding of the fiber. While the approach is useful for power-scaling demonstrations, it is not practical for operational lasers in terms of both reliability and ruggedness. In the work proposed here, we plan to develop and test high-power, all-fiber pump combiners to replace free-space optics for pump transport and allow construction of “all-glass” fiber lasers. The pump couplers must be compatible with polarization-maintaining (PM) LMA fibers used in the beam-combined systems needed to generate DE power levels. Also, given the interest, for some applications, in “eyesafer” DE systems, the couplers should work with not only Yb-doped fibers, but also with Tm-doped, 2-micron-wavelength fibers. |

| Title: | Development of Optimizer for Noise Reduction for Military Airfields and Surrounding Areas |
| Abstract: | Emerging new military high-performance aircraft and most current fighter aircraft generate community noise footprints that are in many cases 10 times or larger in size than current transport commercial aircraft. These higher levels lead to community annoyance, expensive and restrictive noise mitigation, and restriction of operations. Noise reduction technologies have been developed and employed on commercial aircraft engines giving significant reductions in community noise. However, few, if any, of these technologies have direct application to military high-performance jet engines. DoD is funding research to develop advanced modeling tools for community noise exposure and for noise reduction techniques. These tools are being developed to improve the military’s capabilities to assess and to potentially reduce its operational noise. However, for these tools to achieve their full potential, a system needs to be developed to optimize operational flight procedures that reduce community noise exposure while minimizing nonstandard flight procedures. This optimization system will provide the most cost effective near-term solution for jet noise reduction for the military that can be applied to any military aircraft at any airfield for relatively small incremental costs. The initial localized noise reduction expected from operational modifications is expected to be approximately 3 to 6 dB DNL. |

| Title: | Mission Impact and Readiness Assessment Tool for Critical Transmission Assemblies |
| Abstract: | Impact Technologies with its OEM partner Boeing, proposes to use a combination of newly developed technologies and leverage existing technologies to develop a comprehensive software suite that will assist the Navy personnel in accurately and quickly assessing the impact of actual aircraft usage on critical transmission components and therefore, on overall reliability and mission readiness. It is not uncommon to have the aircraft experience the mission mix in actual use that is significantly different from the mission mix anticipated during the design stage. A different mission mix would therefore mean a potentially lower reliability and mission readiness at any given time. It is critical that tools are available than can accurately assess effects of such deviations on individual tail-number basis as well as at the fleet level. The innovations in this proposed effort will include: a) A graphical drag-and-drop system-level modeling tool to represent multiple failure modes for multiple components in complex transmission systems, b) Computation of individual component damage rates and therefore associated reliability using system level inputs such as the flight regime definitions, c) A reliability roll-up of different components in a “transmission chain” with due consideration to serial and parallel paths and interdependencies. |

| Title: | Gearbox Load and Life Simulation Software |
| Abstract: | Gear tooth surface fatigue (pitting) is common precursor failure mode that leads to excessive gear vibration, liberation of debris particles that damage ancillary components (e.g. bearings), and serves as crack initiation sites that lead to eventual catastrophic tooth failure. Current gearbox life estimation techniques commonly underplay the significance of gear tooth surface fatigue due to the complexity of the phenomenon involved. In this Phase I program, technologies necessary for rigorous inclusion of surface fatigue failure will be developed to provide a better estimation of gearbox life for a given set of experienced (past) and anticipated (future) mission profiles. Finite element analysis will be coupled with a detailed mixed-elastohydrodynamic lubrication model and continuum damage mechanics approaches to predict damage accumulation rates in the material microstructure. Estimations of dynamic loading will be obtained through lumped-parameter analysis of the gearbox system. The completed software will provide analysts with a tool to predict the current damage state in helicopter gearboxes and evaluate remaining useful life for anticipated mission profiles. |

| Abstract: | The overall objective of the proposed effort is to build a methodology and the associated computational tools that predict component life for rotor wing drive systems. This will be achieved by adding mission load variability to VEXTEC’s existing gear component life prediction tool. The goal is a framework that accounts for mission variability and gear fatigue damage and produces a comprehensive assessment of drive system performance in an operational environment. This framework will incorporate the use of both high and low fidelity models to predict component performance, and will be based on existing VEXTEC durability prediction software used for Army land vehicles. This software accounts for each component in a complex system to produce an overall drive system life prediction. The tool will be developed in Phase I for a simplified H60 helicopter gearbox system. The tool will be used to predict the system’s performance based on component material and loading, system design, and mission load variability. The successful prediction of system performance will be used to demonstrate conceptual feasibility of implementing the component life prediction tool. |

| Title: | Pilot Physiologic Assessment System |
| Abstract: | The proposed Pilot Physiologic Assessment System is a comprehensive medical monitoring system capable of measuring standard medical indexes such as heart rate, oxygen saturation, respiration rate, oxygen consumption, carbon dioxide production, and nitrogen levels. PPAS will be capable of both monitoring physiologic conditions and warning individuals of potential hypoxic state to aviators or persons conducting missions above 10,000 feet. The approach of the Pilot Physiologic Assessment System will be to use measured physiologic, metabolic and ambient values to create safe boundary limits during hypoxic exposure and allow for warning signals to be presented. Orbital Research (Cleveland, Ohio) with partners at NASA Glenn Research Center will develop a wearable sensor suite to monitor physiologic metrics of aircrews. The acquired indexes will allow physiologic changes to be tracked, warning signals to be generated, and hazards of hypoxia to be mitigated. Accurate prediction of deleterious changes from hypoxic exposure requires first accurate sensors. This Phase I program will focus on developing a non-invasive, pilot worn sensor suite capable of monitoring physiologic metrics to accurately predict and issue a warning of a hypoxic state to the user. |

| Title: | High Reliability, Miniature Personal Hypoxia Monitoring System |
| Abstract: | Accidental reduction in the oxygen available to a fighter pilot at high altitudes can lead to insidious hypoxia, where symptoms are almost unnoticeable before loss of consciousness in less than a minute. Under such situations, an accurate hypoxia monitoring unit that can predict the early onset of hypoxia – leaving sufficient time for the pilot to take remedial action – is essential. The existing commercially available technique for hypoxia monitoring, pulse oximetry, measures arterial hemoglobin oxygen saturation (SO2), but has been proven an unreliable technique for the monitoring of in-flight hypoxia. Radiation Monitoring Devices (RMD) proposes to develop a real-time, versatile near infrared spectroscopic (NIRS) instrument that can detect the onset of hypoxia with minimal false positive and false negative rates. The NIRS instrument will simultaneously measure multiple physiological parameters apart from the blood oxygen saturation, in order to infer the onset of hypoxia with no false negative rates. The instrument will also have no false positives that can cause unnecessary distraction to the pilot during crucial situations. For comfort and safety reasons, the instrument will be made highly compact and non-invasive, and will not interfere with any of the numerous life supporting equipment worn by the pilot. Additionally, the monitor will take into account the statistical variation in an individual’s response to altitude and reduced pressure, to improve its accuracy and make it more universal. The Phase II prototype will be tested in hypobaric chambers used for pilot training at the end of the program. |

| Title: | The HAWK™ Hypoxia Detection and Alerting System for Military Pilots |
| Abstract: | Military aircraft that fly at high altitudes and/or conduct high-g maneuvers require sophisticated safety systems to prevent the pilot from becoming susceptible to the negative effects of hypoxia and gravitational loss of consciousness. Pressure breathing and g-suits help to address these issues; however, a noninvasive warning system is required to alert the pilot to physiologic conditions signaling a hypoxic condition. This is complicated by the highly dynamic environment (pressure breathing, g-loading, pilot movement, irregular breathing, anti-g straining, mask seepage, hypoxia tolerance variation) and that the system must be adaptable to existing systems without modification by the component/system vendor. Safe, Inc. has conceived of a self-powered/low- power wireless noninvasive hypoxia sensor suite that offers ultra-high accuracy measurement (>99%) of blood/breathe oxygenation status with the superior fault- mitigation technology and near real-time responsiveness of hypoxia sensing. Fault mitigation and measurement accuracy is afforded by multi-modal sensors that assess O2 and CO2 metabolism as well as blood oxygenation. Advanced algorithms are employed to account for pilot movement and low blood perfusion. Sensors are mask-mounted and communicate wirelessly to a fore-arm mounted alerting system. |

| Abstract: | Information Systems Laboratories, Inc. (ISL) proposes to team with Applied Physical Sciences Corp.

APS is a recognized leader in the development of advanced acoustic sensors and signal processing. ERAPSCO is a joint venture of USSI and Sparton, the world''''''''''''''''s leading sonobuoy manufacturers. Exploitation of both acoustic and electromagnetic signals emitted by submarines offers new possibilities for sensor queuing and data fusion to reduce false alarms.

We will develop appropriate signal and information processing algorithms to provide a robust multi-modal solution that improves initial detection performance (PD/PFA), target kinematic predictions (tracks), and target identification (target/on-target) based on features in both measurement domains. Data will be collected in Phase I to validate sensor and noise models and to make recommendations for an engineering prototype of a compact sensor package. This information will be used in Phase II to develop and test prototype a sensor with the support of ERAPSCO. |

| Title: | Combined Acoustic and Electric Field Sensing Buoy for Marine Surveillance |
| Abstract: | Buoys for marine surveillance typically employ acoustic sensors for target detection and classification. A wide variety of sonobuoys have been developed for this application. However there are situations, particularly in littoral environments, in which the efficacy of acoustic sensors can be significantly compromised. In these instances, some level of performance enhancement may be possible by using supplementary sensing techniques. One option is the use of underwater electric field (E-field) sensors to detect electromagnetic fields generated by the cathodic corrosion protection systems typically employed on marine vessels. A buoy capable of detecting these signatures in addition to the traditional acoustic signatures could offer significant advantages, particularly in environments in which the quality of the acoustic data is compromised. QUASAR Federal Systems, a world leader in EM technology, proposes to develop underwater E-field sensors appropriate for integration into a combined acoustic/E-field sensing marine surveillance buoy. Working with Ultra Electronics Undersea Sensor Systems. Inc. (USSI) we will also generate a conceptual system design for a combined sensor buoy. In addition, we will partner with Applied Signal Technology (AST) to develop algorithms to fuse the acoustic data with E-field data and characterize the resulting performance. |

| Title: | Data Fusion of Electric Field and Acoustic Data |
| Abstract: | Conventional acoustic ASW methods are limited in littoral regions, where multipath caused by widely varying sound speed profiles and cluttered boundary conditions is concurrent with high ambient noise. For this reason additional detection methods are desirable. Many potential targets of interest generate incidental electric fields from the galvanic potential field generated by dissimilar metals in contact with seawater. Ultimately, these low- frequency e-fields propagate through the water and can be detected at a moderate distance with e-field sensors; when combined with the acoustic data, the fused data can provide additional performance in terms of reduced false alarm rates, tracking, and classification. The opportunity, then, is to develop a tactically deployable, hybrid e-field and acoustic buoy that can support a multilayered data fusion approach to improve airborne ASW capability in cluttered littoral regions. This program will develop a conceptual buoy design that incorporates both the acoustic sensor and the e-field sensor for tactical surveillance and classification of marine vessels. The design will include in- buoy signal processing algorithms for data fusion of the e-field and acoustic sensors to increase probability of detection. System performance metrics will be predicted through simulation. |

| Title: | Enhanced CMC Performance Via Sealant Application |
| Abstract: | High cost and poor environmental performance of CMCs are limiting their deployment in many defense applications. In particular, the JSF platform requires improved durability for a targeted CMC system which is already qualified and in production. Primary motivation for this Phase I effort is to reduce cost. CMCs, although known for their benefits of lightweight and better performance at elevated temperatures, their costs are relatively high compared to metallic counterparts. Cost reduction can be achieved through improved durability or reducing processing steps. Durability is a concern due to high temperature service and harsh environments. Degradation of these CMCs in humid/salt environments is of significant concern to the Navy and this need to be addressed urgently as JSF program advances toward production. In this Phase I project, a sealant application is being proposed to provide protection against pest oxidation at intermediate temperatures during service. The work will be conducted in close collaboration with a defense prime contractor along with other partners for mechanical testing, oxidation modeling, and material suppliers. Critical technical objectives to be addressed in this Phase I project include optimization of the CMC surfaces for better environmental performance and improved reliability along with potentially lowering cost. |

| Title: | Environmentally Protective Coatings for Ceramic Matrix Composites |
| Abstract: | In order to make ceramic matrix composites (CMCs) into a useful class of materials for fabricating aerospace structures, there are several key issues that need to be resolved. One of these issues concerns the performance of CMC at intermediate-high temperatures. Oxidation of the interface coating used to control the crack deflection properties and other serious issues related to the ingress of moisture can significantly impact the long-term reliability of CMCs. The goal of this program is to develop a low cost, easily applied two-part coating system to both reduce the open porosity and provide an effective oxidation barrier. A simple external sealant is unlikely to provide the long-term protection required for CMCs in operational use. There are a number of issues to be overcome in order for any coating system to be effective. This proposal identifies some of those issues and details an approach for overcoming them. |

| Abstract: | Techniques to retrieve militarily relevant parameters of the nearshore region using panchromatic or single-channel electro-optical (EO) data have been demonstrated. However, airborne sensors are being developed and fielded that collect multi-spectral data and the present-day methods do not take advantage of the added information contained in the multi-channel data. In addition, EO systems are restricted to daylight operations; a limitation overcome by infrared (IR) systems. Therefore, under this Phase I effort, existing data of the littoral zone from multi-spectral and IR imagers will be used to study the improvements for bathymetry and current retrievals using multi-spectral and IR processing compared to results obtained using panchromatic, EO imagery. In addition, a state-of-the art ocean-imaging model will be exercised to determine the expected SNR from observing the ocean surface with a multi-spectral imaging system. The overall objective of this SBIR program is to develop algorithms that utilize multi-spectral and / or IR imagery for enhanced ISR products in the littoral zone. |

We propose to investigate the use of existing Navy turret based sensors to supply the needed infrared and multi-spectral data for these missions. We will determine the basic requirements and the utility of several turret based sensors. Then we will determine the feasibility of processing the data with near-shore characterization algorithms. The goal is an operational capability for the navy to support military operations in the near shore and surf zone. |

| Title: | Novel techniques for multipath mitigation for airborne Global Positioning System (GPS) receivers |
| Abstract: | US Department of Defense is heavily dependent on the Global Positioning System (GPS) for geolocation, navigation, timekeeping and other military operations. Multipath due to the structure (platform on which the GPS receiver is mounted) scattering can degrade the accuracy of GPS measurements (code and carrier phase) by tens of centimeters. For an airborne platform, reflection or diffraction of the satellite signal from wings, tail, stabilizers or any other large appendage of the aircraft fuselage leads to signal multipath, and these multipath cause biases in code and carrier phase measurements. During this project, we propose to study the performance of two novel adaptive weighting algorithms in the presence of platform generated multipaths. The adaptive weighting algorithms are designed for GPS anti-jam antennas (CRPAs) to null the interfering signals without distorting the satellite signals. We will investigate the performance of the two weighting algorithms in simultaneous nulling of the interfering signals and mitigation of the platform generated multipath. The two weighting algorithms use the knowledge of the in situ antenna manifolds to minimize the distortion of the satellite signals. The sensitivity of the two algorithms to errors in antenna manifold will also be investigated. Our investigation will also include reduced size CRPAs whose foot print is limited to 5" in diameter. |

| Title: | Innovative Adaptive Algorithms for Multipath Mitigation and Interference Suppression for GPS Receivers |
| Abstract: | The satellite-based GPS systems are vulnerable to intentional and unintentional interferences. Much work has been done on the development of anti-jam techniques using adaptive arrays for GPS receivers. Almost all of the anti-jam techniques proposed are based on the standard Capon beamformer or its robust variations. To improve the interference suppression performance of broadband jammers and to increase the number of narrowband jammers that can be suppressed, STAP and the related SFAP techniques have been used with beam forming/null steering. Multipath mitigation is another important challenge for GPS receivers. If the multipath time delays are small, the direct and the reflected paths are highly correlated and the multipath can affect the accuracy of the GPS receiver significantly. However, none of the aforementioned adaptive array techniques can work well when the desired signal is highly correlated with its multipath signals. The main objective of this program is to develop innovative techniques for the effective mitigation of multipath effects on airborne anti-jam GPS adaptive antennas. The secondary objective is to develop, test and deliver a software-based simulation capability that realistically simulates a GPS receiver equipped with a small anti-jam GPS antenna array operating in a multipath and interference environment. |

| Title: | Assessing Electromagnetic Scattering Properties of Small Boats in Littoral Environments Using Hardware Accelerated Computing |
| Abstract: | The goal of this effort is to provide electromagnetic scattering tools (radar cross section/RCS codes) for small boats in littoral and deep ocean environments. This goal is within the larger scope of developing electromagnetic (EM) modeling and simulation (EMMS) tools for large scale simulations as is the case with boats within their innate environment (a sizeable patch of the surrounding ocean). The major challenge is the numerical size of the problem at hand, and the difficulty of incorporating rough sea effects. Applied EM is proposing state of the art computational tools, incorporating full wave and hybrid techniques that exploit hardware accelerated algorithms. Our approach is to develop a toolset of hybrid (moment method-high frequency) methodologies that function on the latest general purpose graphical processing units (GPGPU) boasting computational speed of 4TeraFlops. This speed has the potential to carry out in core computations for large dense matrices modeling realistic structures by exploiting GPGPU’s parallel architecture. When combined with recent CPU speeds and memory growth, this approach can bring a paradigm change in computational EM (CEM) codes and their utility for design applications. |

| Title: | ACCESS - ACCelerator for Electromagnetic Scattering Simulations |
| Abstract: | Determining the scattering properties of small boats on a rough sea surface is a problem of high importance to the Navy. The resulting simulations require large amounts of compute time and mechanisms are sought to accelerate them. The demand for highly realistic graphics has pushed graphics processing units (GPU) on video cards to the point where they easily outperform general purpose processors for floating-point operations. The goal of this project is to develop a GPU-based system to accelerate widely used electromagnetic modeling tools. During the Phase I, we will accelerate an out-of-core solver for linear equations on GPUs. We will test this implementation by comparing the results to a trusted simulation code. In addition, we will perform parallel scaling studies, develop a performance model and design a hardware configuration that will enable simulations of interest to the Navy within reasonable time. During the Phase I Option period, we will tune these prototypes and accelerate a parallel iterative solver on GPUs. The goal of the Phase II project is then to tune these algorithms and incorporate them into commercial electromagnetic simulation codes. We will also implement solvers with higher precision in order to accelerate simulations with demand for high accuracy. |

| Title: | Hardware Acceleration of Method of Moments (MoM) for Large-Scale EM Scattering Computations |
| Abstract: | Virtual EM is proposing to build a cluster utilizing a commercially available special purpose processor. The proposed system will offer a performance-to-price ratio, which is “five times” better than the leading commercial clusters. Using this cluster and Virtual EM’s 3D Method of Moments simulator, one will be able to accurately model small boats (including the surrounding patch of sea) within a reasonable simulation time and budget. The (performance-to-price) ratio will increase as the number of nodes in the cluster grows due to linear speed-up and the unit price dropping. Phase I will establish benchmarks using a one-node system, and a 10-node prototype cluster will be built in Phase II for modeling realistic targets. |

| Title: | Improved Close Air Support Effectiveness Through a Noise Cancellation Device |
| Abstract: | The rejection of transient and broadband gunshot noise signals in the presence of speech has the problem that speech is also transient and broadband. Although adaptive filtering and/or matched filter rejection will have some application, additional characteristics that separate gunfire from speech are needed for optimal noise cancellation. This proposal is based on those two features – the difference in directions of gunfire and the talker relative to the handset microphone, and on the closer proximity of the talker relative to the sources of gunfire. These additional features are basic to the proposed approach that uses new, patented technology. This new technology, termed PrivacyFone, employs a small microphone array that emphasizes the talker’s voice signal by taking advantage of the fact that the array is in the near field (acoustic induction field) of the speech and not in the near field of the gunfire. The same array also rejects signals from directions associated with the gunfire. These features, basic to PrivacyFone, provide a way to discriminate against gunfire and enhance the speech signal. Any remnant of environmental noise that remains in the transmitted signal is then further rejected by an adaptive filtering scheme. |

| Title: | Improve Close Air Support (CAS) Effectiveness Through Noise Cancellation Device (NCD) |
| Abstract: | The objective of this proposal is to present a novel and promising solution for a noise cancellation device (NCD) that could be easily mounted on the top of military radio’s handsets used by the Joint Terminal Attach Controller/Forward Air Controller (JTAC/FAC) personnel and effectively filter out noise resulting from artillery fire and transmit voice only. To ensure the quality, the proposed device has three noise reduction and cancellation modules. The first one is a microphone array with adaptive beam-forming which utilizes the spatial domain information for noise reduction. The second one is a noise cancellation unit which utilizes the tempore domain information and adaptive filtering technology. The last one is an intelligent noise reduction system especially for military sound reduction which utilizes our speech recognition technology. Since the company has developed three microphone arrays products with noise reduction and cancellation, many of our existing technology, algorithms, software tools, and hardware platforms can be used to this project directly to ensure the success and quick deployment. |

| Title: | A Novel and High Performance Noise Cancellation Device for Battlefield Applications |
| Abstract: | We propose a novel, high performance, and standalone system for improving close air support (CAS) effectiveness. First, we propose a standalone noise cancellation device (NCD) that can be inserted between the handset and the transceiver. As a result, there is no change to the existing communication system. The NCD is self-powered from its own battery and equipped with a microphone and a digital signal processing (DSP) chip to process the signals from the handset mic and the mic in the NCD. Second, in the NCD, we propose to apply blind source separation (BSS) algorithms to untangle speech from background noises. One BSS method is the Independent Component Analysis (ICA) and another method is known as Adaptive Decorrelation Filter (ADF). Our team has applied both ICA and ADF to various applications. Third, since there may still be residual noise after the BSS stage, we propose to apply a fast convergence adaptive filter to further eliminate the residual background noise. The particular adaptive filter was developed by this team some time ago and can at least double the speed of convergence as compared to a conventional adaptive scheme. The proposed algorithms will be implemented in DSP in Phase 2. |

| Title: | RFID Based Composite Smart Patches Using Direct Print Strain Sensors |
| Abstract: | Composite patch repair systems have become increasingly relevant to modern military and commercial aviation for repairs of structural damage to aircraft surfaces and structures. A technique is needed to monitor the structural health of these composite patches to ensure structural integrity and safety of the repair without compromising structural performance of the patches. In order to monitor the boding state of the patches throughout their lifetime a method for embedding strain sensing elements directly onto the composite ply used in these patch repairs is sought. Luna, along with teeming partner Robocasting Enterprises LLC, proposes to develop a direct-write process for embedding strain sensors in composite repair patches using conductive inks. A RFID based transducer interface will also be developed and combined with these novel strain transducers to create a Smart Patch platform which enables maintainers to easily read and track the health of composite patch repairs on aircraft structures. Luna has developed extensive expertise in composites, embedded sensing, transducer development, conductive polymers, and integrated structural health monitoring (ISHM) and will leverage this experience to successfully develop the propose Smart Patch system. |

| Title: | Innovation in Strain Sensing and Damage Detection in Composite Repairs using Printed Gages |
| Abstract: | Smart composite repair patches, capable of detecting static strain, is a coveted technology for enhancing the fidelity and cost-effectiveness of composite repairs. Direct Write thermal spray (DWTS) is proposed as an innovative approach for fabricating and embedding strain sensors within multifunctional composites. As a novel processing technology platform, DWTS enables low profile, fine feature patterns, such as strain gages, thermocouples, and crack sensors, to be deposited onto composite laminates and embedded within multilayered structures. These unique features render DWTS highly applicable to providing the necessary strain sensing capabilities for integration with composite repairs. The main objectives during the Phase I and Phase I option are to embed strain sensors within composite layups, and demonstrate their functionality and durability through performance testing. Complementary modeling efforts will focus on optimizing sensor integration with composites. Data acquisition and interrogation solutions will also be identified early-on in the technology development process to further drive the Technology Readiness Level beyond a TRL-5 by completion of the Phase II. |

| Abstract: | In this Phase I program, Triton and its team members are proposing the development of a wireless technique for the health monitoring of composite repair panels as well as other composite structures. A wireless approach is much more compatible with the composite fabrication process, and greatly simplifies the interrogation of a fielded component. This technique can be used to monitor the integrity of a structural component, either manually during routine maintenance, or continually during operation. |

| Title: | Hyper-Elevation Modeling of Terrain, Topography, and Urban Environments |
| Abstract: | Recent advances in technology have exposed enough computing power in easily available hardware that geometry synthesis algorithms that we were previously prohibitively compute-intensive are now a possibility. There is significant untapped potential in this area that has gone underutilized in existing simulation systems. Increasing the realism and accuracy of synthetic environments has become a priority, but current methods of simulating complex terrain features requires manual, labor-intensive systems to generate certain complex terrain features accurately. In this effort, Cognitics proposes to research and define new techniques, algorithms, and methods to simulate complex terrain features and urban environments, and use these techniques to extend existing real-time simulation systems to make them capable of real-time modeling, integration, and interaction with complex terrain features. Cognitics has proven experience working with and developing software for the storage and analysis of geospatial data, computational geometry and 3D visualization systems. Notably, the Principal Investigator for this proposal, Kevin Bentley, is the software architect that designed the Master Database (MDB), currently used by SE Core. In this effort, Cognitics will partner with CAE to enhance the Run Time Publisher (RTP) system allowing it to provide complex terrain models in real-time. |

| Title: | Hyper-Elevation Modeling of Terrain, Topography, and Urban Environments |
| Abstract: | Image Generation systems today currently can not easily represent Digital Elevation Models (DEMs) with unique but important topographical features such as tunnels, overhangs, multi-level highways, etc. These types of features must be hand-crafted in an off-line process with the final static implementation loaded at run-time. All abstract information defining the feature as well as scalability is lost with this approach. In this SBIR, we propose a new approach where the abstraction of this feature data is preserved by creating the scene directly from the abstraction data itself. We will load this topographical feature source data during run-time along with the other source data directly to the scene. This underlying scene will be updated to allow dynamic interaction with these features during a training simulation exercise. We will use an XML-based approach to assemble various types of feature data that is loaded upon at run-time. This XML-based approach will be extended to support the existing military database re-use initiatives, such as NPSI, MSB, CDB and SE Core. This approach allows topographical feature source data to be changed and then re-visualized with no intermediate processing steps. |

| Title: | Underwater Vertical Electric Field Detection |
| Abstract: | Underwater electric field detection in the vertical (Z-component) direction is becoming more important in anti-submarine warfare (ASW) to detect and classify marine vessels in addition to the horizontal (X and Y component) plane. Leveraging on our extensive experience on photonic approaches for electric field sensing and RF photonics, AGILTRON proposes to realize a feasible class of vertical electric field detectors under water using Brag gratings, PZT electronic optical materials and other WDM technology. This sensor is passive and compact with a meter-size antenna. Because of the intrinsic electromagnetic immunity of optical fiber, the detected signal can be sent to a distanced center processing terminal insulated from the static electric and electromagnetic fields. In the proposed sensor, the DC and extremely low frequency electromagnetic (ELFE) signals are converted into AC signals. So the sensitivity of the DC and ELFE signals can be improved in this sensor by avoiding 1/f noise. In the Phase I program, we will build a model to simulate the performance of the proposed sensor. At same time, a prototype will be set up to demonstrate its functionality in detecting electric fields. Then a design with its preliminary performance based on ASW requirements will be presented for the Phase II Program. |

| Title: | Underwater Vertical Electric Field Detection |
| Abstract: | Information System Laboratories, Inc. (ISL) proposes to team with ERAPSCO, a joint venture of USSI and Sparton, the world''''s leading sonobuoy manufacturers, to develop a low-cost underwater E-field sensor capable of collecting all electric field signals emanating from submarines. In particular, a sensor capable of measuring the vertical component of the field in addition to the horizontal components will be developed. This will enable exploitation of all low-frequency electric field signals emitted by submarines and offers new detection modalities that will facilitate vessel classification, discrimination from surface vessel track, and data fusion with acoustic sensors. Data will be collected in Phase I for various floating and on-bottom configurations to validate sensor and noise models and will be used to determine the optimal aperture size and electrode location and make recommendations for an engineering prototype of a compact low-cost three-axis electric field sensor. This information will be used in Phase II to develop and test a prototype sensor with the support of ERAPSCO. |

| Title: | Underwater Vertical Electric Field Detection |
| Abstract: | Acoustic sensing based sonobuoys are used in surveillance for detection and classification of marine vessels. However, there are situations, particularly in littoral environments, where the efficacy of acoustic sensors can be significantly compromised. In these instances, supplementary sensing techniques can provide performance enhancement. Passive electric field (E-field) sensors have the potential to provide useful information for tactical surveillance and classification of marine vessels, but current marine E-field sensors collect only horizontal E-field measurements. A sonobuoy capable of collecting vertical E-field in addition to horizontal components would enable exploitation of all E-field signals emanating from a submerged vessel. QUASAR Federal Systems proposes to develop an innovative underwater E-field sensor appropriate for collecting vertical E-field measurements over a large effective aperture that can be integrated with sensors that measure the horizontal E-field components. The vertical E-field sensor will be a low-cost design suitable for scale-up to mass production. The E-field sensors developed in the present program will be integrated into a standard sonobuoy in Phase II in collaboration with Ultra Electronics Undersea Sensor Systems Inc. (Ultra-USSI). We will also partner with Applied Signal Technology in the present effort to develop algorithms to model the proposed sensor and predict the resulting performance. |

| Title: | Optical Coatings for Deep Concave Surface |
| Abstract: | The objective of this SBIR topic is to develop methods to apply robust, high operating temperature anti-reflective coatings, over the wavelength range 3 to 5 microns, to the inside of deep concave surfaces, including a tangent ogive infrared dome. In Phase 1 we will develop methods which control the coating thickness across the interior surface of the dome such that the coating performance is optimized over a wide range of look angles for an IR seeker positioned inside the dome itself. We propose to solve the thickness control challenges by using shadow masking techniques to control uniformity, coupled with 3 dimensional mathematical modeling to predict deterministically the shape of the shadow mask. This approach will save considerable time and expense. We will use Ion Beam Sputtering (IBS) technology to deposit the Anti-Reflective coating on the interior of the dome, (in Phase 1 option and in Phase 2), thereby gaining the benefits of the high energy IBS deposition process. Those benefits include: Amorphous film structure, near bulk density, improved film adhesion, automated deposition process, and environmental stability. |
