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

Title:AN/ASQ-233 Magnetic Anomaly Detection (MAD) Light Weight Towing System for Light Weight Helicopters and Small, Vertical Take Off Unmanned Aerial Vehicles (UAVs)
Abstract:This SBIR Phase I proposal describes the development of a conceptual design for the Light Weight Towing System (LWTS). Polatomic and Meggitt Defense Systems, Inc. will join their respective magnetic sensor and reel-in/reel-out towing system expertise and experience to develop the requirements for an affordable light weight ASQ-233 MAD towing system for light weight helicopter and small UAV applications. The design objectives will be to develop a design for a self contained very light weight universal towing system that will support multiple platforms. The towing system will consist of a non-magnetic stable tow vehicle, non-magnetic tow cable and a light weight reeling machine that can deploy, tow and retrieve the ASQ-233 MAD sensor. Tradeoff studies will be performed during the Phase I contract regarding system weight, aerodynamic requirements, towing speeds, cable characteristics, towed body design, and platform interchangeability.

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

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

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

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

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

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

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

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

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

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

Title:Rotary Wing Dynamic Component Structural Life Tracking with Self-Powered Wireless Sensors
Abstract:KCF Technologies is proposing to develop a novel tool for tracking the fatigue life of rotorcraft components. The tool will consist of a suite of wireless data acquisition sensors, diagnostic and prognostic fatigue life algorithms, and a data management system for storing and accessing component status and projected life. Environmental and usability factors for the sensor system necessitate wireless communication to the nodes. An essential part of enabling such a system is piezoelectric power harvesting. In Phase I, KCF will carry out preliminary hardware demonstrations showing the feasibility of implementing an autonomous sensor system for storing component fatigue life data, evaluate and propose updates to current HUMS diagnostic and prognostic algorithms, and assess the feasibly of implementing a global data management system.

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

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

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

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

The sensor system will comprise an expendable buoy with a total-field magnetometer that will be deployed by the ASW aircraft immediately prior to the localization phase of the mission. Various suspension systems and deployment schemes will be studied to determine the optimum configuration for this application. The performance enhancement will be validated for various geometries, search platforms, targets, geomagnetic-noise levels, and geology-noise levels.

Title:Geomagnetic Reference Sensor System (GRSS) for Air Anti-Submarine Warfare (ASW)
Abstract:This SBIR Phase I proposal describes the development of a conceptual design for the Geomagnetic Reference Sensor System (GRSS). Polatomic and USSI have joined their respective magnetic sensor and buoy building expertise and experience to develop an affordable sea deployable geomagnetic reference buoy to reduce the geomagnetic noise on airborne MAD systems. The sensor is a miniature high- sensitivity scalar laser magnetometer derived from the ONR sponsored Miniature Broadband Laser Magnetometer (MBLM) Phase II Program. It is designed to sell for less than $3000.00 in volume production. The MBLM offers a state-of-the-art capability for measuring scalar geomagnetic fields with sensitivity better than 1.0 pT/ãHz from 0.01 Hz to 30 Hz. The MBLM design is based on four innovations: 1) Optically-driven Spin Precession (OSP) locked-oscillator He4 mode for the observation of the magnetic signals, 2) miniature helium-4 cells, 3) fiber-coupled laser pump source for optically pumping helium isotopes, and 4) miniature omni- directional sensor having full sensitivity on all headings. In Phase I, the anticipated noise sources for the geomagnetic buoy will be characterized and ancillary sensors and suspension systems will be added to the buoy to allow mitigation of motion and ocean wave noise.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

YTP, in collaboration with the University of Rhode Island, has been working on the development of innovative technologies that should result in durable, lightweight, Li-Ion batteries with significantly increased life performance at elevated temperatures. YTP proposes to take the innovations and concepts in this proposal (cathode type, stabilized electrolyte, binder solubility, stabilized surface coated cathodes, etc) and demonstrate that the combined enhancements will significantly improve the upper operating temperature. These improvements will also result in an ability to operate at higher voltages which, when combined with lightweight aluminum hardware, would result in significant increases in energy density and specific energy.

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

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

The Phase I program will demonstrate the performance of the wideband conformal array through state-of-the-art modeling and simulation. The follow-on Phase II program will refine the design and develop a wideband high power transmitter array prototype. Testing of the prototype will validate the simulation and the conformal array transmitter performance capabilities.

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

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

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

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

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

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

Title:Combined Analytical and Experimental Approaches to Rotor and Dynamic Component Stress Predictions
Abstract:The accurate prediction of rotor and dynamic component stresses remains an elusive goal. Despite major advancements in computational fluid dynamics techniques, prediction of the unsteady aerodynamic loads acting on the blades continues to be a formidable computational task, and the accuracy of these predictions remains problematic. Techno-Sciences, Inc. (TSi), in collaboration with the Alfred Gessow Rotorcraft Center at the University of Maryland (UMD), proposes to develop an Advanced Rotorcraft Load Prediction (ARLP) tool for rotor and dynamic components that features the combined analytical and experimental approaches. This ARLAS system will exploit the CFD/CSD coupled rotorcraft analytical framework with the experimental measurements (stress, acceleration, loads, etc.) to constantly improve the analytical predictions via an integrated optimization scheme. UMD has enhanced the features of University of Maryland Advanced Rotorcraft Code (UMARC) with CFD/CSD coupled model.

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

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

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

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

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

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

Abstract:Impact Technologies, with support from the prime JSF manufacturer, Lockheed Martin Aeronautics Company, proposes to develop and demonstrate a system for in-situ calibration of strain sensors on in- service fleet aircraft that are used for structural life tracking. Key tasks in Phase I include: 1) Full definition of the performance specifications and constraints (e.g. safety) that the calibration technology must meet; 2) Selection of potential dynamic input technologies to test - this will include response to low levels of localized periodic forcing functions and controlled impact events; 3) Design and manufacture of test fixtures that adequately reproduce key aircraft structures found where strain gages would be placed in the target aircraft; 4) Creation of an analytical model of the structure to understand the fundamental physics involved and estimate the system’s sensitivity to changes in various input parameters; 5) Testing of the various dynamic calibration technologies by comparing the dynamic response features to response to static loads (i.e. the known baseline); 6) Demonstration of the ability of the techniques and calculation of accuracy in ‘blind’ tests for the Navy; and 7) Analyzing the potential of the technology to meet Navy goals in Phase II and beyond.

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

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

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

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

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

Title:Unique Reactive Material Liners for Shaped Charge Jets against Fortified Structures
Abstract:This proposal addresses the use of reactive materials in a tandem warhead system to enhance wall-breaching capability for targets of concrete and rock. In the system, a precursor shaped charge jet contains reactive material that conditions the target during the penetration process so that the follow-through warhead can push through the target. To maximize effects, the research develops a process used to select reactive materials and/or establishes requirements upon which advanced reactive materials can be based, including base line materials, mixtures variations, as well as new promising combinations. As a means to utilize reactive armors in shaped charge liners, high-strain-rate and equation-of-state properties of selected reactive materials will be characterized. These descriptions will be incorporated within hydrocodes such as CALE and CTH to examine methods to accelerate liners and form jets using reactive materials and penetration dynamics into targets. Phase I will select reactive material candidates, develop several scale-model shaped charge designs, and establish improvements in target perforation relative to a base-line aluminum liners. Phase II will further improve first order HSR and EOS models, refine the selection and design process, fabricate shaped charge liners at scale model size, test liners using flash x-ray coverage and assess wall-breaching capabilities.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Abstract:In this program, Spectra Research will investigate issues related to the design and development of aircraft-mounted communication antennas that do not cause significant aerodynamic drag and do not require structural penetration of the aircraft hull, while providing vertically polarized coverage to the horizon and circular polarization the zenith within a frequency band of 30-2000MHz. Concepts will be explored that can be utilized for conformal application of new antennas onto curved surfaces. As a consequence, new antenna concepts that will provide for multiple functions in a common pliable aperture will be explored and optimized. When antennas are being designed around these new concepts, advanced tools and techniques are required to accurately simulate the antenna structure and optimize the antenna performance, while exploiting the advantages of a complicated electromagnetic environment that may include custom materials such as metamaterials (including electronic bandgap structures) as well as artificial dielectrics and artificial magnetics. The objective of the proposed research program is to demonstrate new computational tools and design methodologies for optimizing antenna performance while demonstrating advanced antenna constructs that may be utilized to reduce antenna profile and size, and to increase radiation efficiency in an ultra broadband, common aperture configuration.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Abstract:As the Navy moves forward with plans to augment the conventional assets with unmanned sensor vehicles, standoff weapons, and intelligent command and control (C2) systems we find more data will be available from these remote assets that is needed to maintain an accurate, complete, and consistent Common Tactical Picture (CTP). Design considerations for multi-platform, multi-layer data fusion are discussed relative to the solicitation requirements. Bandwidth limitations, correlated (redundant) data considerations, fault tolerance issues, distributed/decentralized design concepts, and network topology impacts are summarized with respect to alternative architectures. A multi-layer fusion architecture robust against the issues is presented. The generalized and novel application of correlated data management and optimum bandwidth utilization is presented with detailed descriptions of benefits. Alternate commercialization markets such as border security, port and physical plant security, air traffic control, and others are presented.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Phase one will research the core concepts and a design for their integration with existing training systems. The ALLIVE effort will develop designs to address improved “Kinesthetic feedback”, to help the soldiers retain their lessons from either LF or VE. It will advance the technology for improved sniper/counter sniper training better incorporating non-line of site kills and weapons ballistics. It will examine solutions for rapidly deployable indoor/outdoor/urban position tracking to allow insertion of LF items into VE training.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Abstract:The Software Communications Architecture (SCA) builds upon the Common Object Request Broker Architecture (CORBA), a powerful middleware standard that enables the development of platform- independent, dynamically loadable object-oriented software components.

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

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

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

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

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

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

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

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

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

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

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

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