Title:Microchannel Heat Exchangers for Aircraft Thermal Management
Abstract:Thermal loads from electronics and advanced weapons systems have increased the cooling required from environmental control systems (ECS) in state of the art fighter aircraft. Future aircraft will require advanced heat exchanger technology to minimize the size and weight of the ECS. Microchannels offer improved heat transfer/pressure drop characteristics compared to plate fin heat exchangers, but the expense of manufacturing microchannel heat exchangers is prohibitive. We propose a microchannel heat exchanger that uses low cost manufacturing methods. In Phase I we will develop generalized design methods for microchannel heat exchangers, use these methods to assess the heat exchangers in the F 35 Joint Strike Fighter ECS, and identify the heat exchangers that will benefit most from our microchannel technology. We will design a full size prototype heat exchanger core using the microchannel approach and estimate its performance and production costs. Finally, we will prove the feasibility of our approach by fabricating and testing a proof of concept, microchannel heat exchanger using prototypical, low cost fabrication methods. In Phase II we will design, build, and test a full size prototype heat exchanger under conditions that simulate operation in the F 35 ECS.

Title:Lightweight Compact Micro-Channel Heat Exchangers
Abstract:Mezzo Technologies is currently developing an extremely compact, sturdy cross flow heat exchanger that is particularly effective in a variety of applications. The goal of this project is to optimize current panel design and configuration technology for use on the F-35/JSF aircraft, and examine the overall weight and volume gains by replacing plate fin heat exchangers currently used with Mezzo's cross flow heat exchangers. Mezzo will design four heat exchangers that will satisfy the conditions faced by the aircraft cooling systems. One of the designs will be selected and tested against its modeled predictions. The technology incorporates the use of panels with micro-channel air passages to enhance heat transfer. These panels can be oriented in various configurations to fit specified design envelopes. The designed core will be smaller, lighter, and have reduced pressure drop through both the air and coolant sides. This proposed heat exchanger design would significantly increase the performance of the aircraft cooling systems.

Title:Gas Turbine Engine Noise Modeling
Abstract:Jet noise mitigation techniques are currently under evaluation by CRAFT Tech and NCPA for application to the F/A-18 E/F aircraft. Varied passive technologies, e.g. microjet blowing, corrugations, etc. analyzed at 1/10th scale culminated in full-scale propulsion stand tests of a F404-400 engine during Summer 2004. Under this proposed SBIR, an "End-to-End" Aircraft Noise Footprint Model will be developed for application to military gas turbine engines. The model interfaces CRAFT Tech' state-of-the-art aircraft plume CFD modeling with well-validated, systems level farfield noise propagation modeling to create a high-fidelity capability for evaluating environmental impact of noise emissions from military gas turbine engines and to enable analysis of potential noise reduction technologies, as well as operational changes. The proposed modeling will integrate noise propagation with topographical data to enable the Navy to generate noise contour maps around naval facilities that are intended to receive the Joint Strike Fighter (JSF). The Phase I effort will provide a demonstration of the model for JSF, as well as its demonstration for evaluating design/operational changes consistent with the requirements of military gas turbine engines. A detailed sub-scale test plan will also be developed for obtaining relevant noise data during Phase II to support model validation and refinement.

Title:A High-Fidelity Software Tool for Gas Turbine Engine Noise Prediction
Abstract:Aerodynamically-generated noise from aircraft is a critical factor in the continuing development of aviation, as community noise concerns and the associated regulatory requirements constrain the design of new airplanes. In particular, supersonic jets are known to produce broadband and narrow-band (screech tones) noise, which contributes to structural fatigue, in addition to the strong environmental noise pollution. The ability to accurately predict noise mechanisms in gas turbine engines will therefore constitute an essential component of any program aimed at producing aircraft engines with low jet noise emissions. Thaerocomp Technical Corp. (TTC) is proposing to develop a high-fidelity CFD-based software tool for accurate, affordable, and reliable prediction of jet noise at all speeds (subsonic, transonic, supersonic, and hypersonic) under realistic flight conditions. The bottlenecks that currently prevent the availability of such a tool are identified and the innovative research required to remove them are proposed. The proposed tool considerably simplifies the procedure of specifying boundary conditions and suggests a better way to calculate turbulence-generated noise. The new procedure will also identify the best approach to compute the propagation of noise far-field from the point of generation. One of the objectives of the proposed research is to obtain highly accurate noise prediction results for high speed jets. Procedures to establish the feasibility of the Phase I research are proposed.

Title:Innovative Materials/Concepts for Grease Lubricated Bearings
Abstract:Grease lubricated bearings are widely used in aircraft for driveshaft support, fans, and accessories. These components are a maintenance intensive item requiring regular replenishment or replacement. In addition, occasional failures occur and have resulted in loss of aircraft. Sentient Corporation, in collaboration with SKF/MRC bearings and Sikorsky Aircraft, will study and address the dominant failure causes in aircraft grease lubricated bearings. Leveraging sophisticated in-house test capabilities and extensive prior research into bearing failure modes, Sentient will evaluate existing state-of-the-art bearing technologies and innovative new approaches to identify the most promising avenues for substantially extending life without relubrication. Technologies will be evaluated as a package including design modifications, bearing materials, and lubricants. Sentient will collaborate with MRC and Sikorsky throughout the project to ensure that these technologies are practical and affordable to implement, and to commercialize the improved bearing designs. Phase I will include test and evaluation of prototype bearings equipped with the proposed modifications.

Title:Innovative Materials/Concepts for Grease Lubricated Bearings
Abstract:The U.S. Navy is seeking innovative concepts to substantially improve life of grease-packed hanger bearings on the tilt-rotor V-22 Osprey aircraft. Hanger bearings are especially maintenance-intensive and short-lived. Extending maintenance intervals and increasing bearing life several-fold are goals to be met. Our approach will provide a novel grease that reduces bearing wear many-fold and has extraordinary resistance to oil breakdown. Our grease will not only achieve these goals, but will provide dramatically lower friction. Frictional heat currently prevents bearings from running at desired optimal speeds. Surfaces Research proposes a novel materials approach to address all of these bearing issues as well as provide the Navy with new cutting-edge technology. We propose our innovative grease to lubricate ceramic (silicon nitride) hybrid bearings. Bell Helicopter Textron Inc will partner to provide detailed specifics on bearing performance and hanger bearings. Bell will evaluate Surfaces Research greases in stainless steel and hybrid bearings in their hanger bearing test rig. Our approach will resolve V-22 hanger bearing issues, and will also find numerous related applications.

Title:Automated Creation, Self-Organization, and Adaptation of Multi-Media Tactical System Training Material for Anywhere/Anytime Delivery
Abstract:To reduce the effort of ensuring that multi-media training reflects tactical system operation and actual Fleet use, we propose innovative technology to help automate production of training material, based on emerging standards (Sharable Content Object Reference Model [SCORM], User Interface Markup Language [UIML]). Compared to today's rigid computer-based training, we improve learning effectiveness by dynamically self-organizing a muti-media training sequence to fit the student's knowledge, skills, abilities, past training, role, current demonstrated proficiency, and mission- or doctrine-induced changes to tasks, conditions, and standards. This adaptation incorporates proficiency demonstrated while taking the course, using feedback from online student assessment, student keystroke analysis, and optionally eye tracking. Our architecture is based on lessons learned from our work as a subcontractor on the $100M Army Training Information Architecture-Migrated (ATIA-M) project. We make training interfaces adaptable to display device characteristics - using reverse/forward engineering and transformation technology we developed to deliver U.S. Army Reimer Digital Library documents to handheld devices - and to network bandwidth to deliver courses anytime/anywhere. Our proposed technology integrates with learning content and learning management systems to leverage existing Navy investment, which will be demonstrated live with SAIC's ATIA-M enterprise facility used to host U.S. Army and Department of Homeland Security training.

Title:Handling Qualities Specification Requirements for Maritime Rotorcraft, Vertical Takeoff/Landing (VTOL) Unmanned Aerial Vehicles (UAVs), and Heavy Lift Helicopters
Abstract:ART proposes to develop a technical basis for augmenting the current ADS-33E-PRF to accommodate the needs of improving its applicability to shipboard rotorcraft and heavy lift helicopter flying qualities specifications. The research effort will emphasize the new criteria development, the evaluation methodology formulation, and the analytical simulation toolkit integration. The detailed Phase I objectives are to (1) accomplish a thorough review of the current ADS-33E-PRF and conduct a comprehensive investigation of existing flight test and simulation data to identify areas which need improvement; (2) investigate and evaluate land-and sea-based rotorcraft operational differences and propose new specification criteria for shipboard rotorcraft operations; (3) develop methods for simulation and/or flight test evaluation of the new specification criteria; (4) prototype a new handling qualities evaluation toolkit for shipboard rotorcraft operations that is compatible with industry standard simulation programs, such as FLIGHTLAB or MATLAB/Simulink; and (5) prototype the new toolkit by integrating it with FLIGHTLAB to demonstrate the functionality.

Title:ADS-33 Software Application Package (ASAP) for Naval Rotorcraft Handling Qualities Specification Requirements
Abstract:The U.S. Army Aeronautical Design Standard for rotorcraft handling qualities (ADS-33E-PRF) and its methodologies to define handling qualities criteria have been accepted around the world both as a specification and as design guidance for rotorcraft handling qualities. There are gaps in the coverage of helicopter missions and criteria. These gaps consist of criteria and mission-task-elements related to maritime missions, very large cargo helicopters, handling with external loads, and handling qualities of unmanned aerial vehicles. The original authors of ADS-33E-PRF propose to develop criteria and MTEs to resolve these shortcomings. This work will also result in an ADS-33 Software Applications Package (ASAP). This software will provide a rapid comparison of a helicopter with the new ADS-33 criteria. The helicopter and flight control system may be defined with models in Simulink or Flightlab, or by using transfer function or state space representations. ASAP will show specification compliance graphically, define the response-type, and highlight any unusual aircraft characteristics that should be considered when deriving handling qualities criteria (such as rotor modes at low frequency). The version of ASAP resulting from this work will emphasize maritime missions, and will be upgradeable to include all missions.

Title:Carbon Composites with Improved EMI Shielding
Abstract:The conversion of metal components on aircraft to polymer reinforced composites allows up to 50% weight savings over metal structures. This reduction in weight will enable significant gains in performance (increased range, payload, velocities), and lowering of costs. Composites also provide further advantages of low maintenance and corrosion resistance. One of the obstacles with the use of composites is the lack of electrical and thermal conductivity achieved by their metal counterparts. In particular, the Faraday cage, which protects electronic components on the aircraft from electromagnetic interference (EMI), is lost with the use of insulating polymer resins. On this program, Luna will develop highly conductive resins, adhesives, and gap fillers with the use of single walled carbon nanotubes (SWNT) in conjunction with improved carbon composite fabrication techniques. The resultant composites will achieve up to 80 dB level of EMI shielding required for high power electronic enclosures.

Title:Multifunctional Lightweight Electromagnetically Shielded Enclosure Technology Using Affordable Hybrid Carbon Composite Production Processes
Abstract:The objective of this proposal is to establish a robust EMI coating and shielding methodology integrated onto an advanced hybrid composite electronic enclosure. The hybrid enclosure utilizes a hybrid of high thermal conductivity graphite fibers/foams, structural composite fibers, and metallic materials. The proposed activity herein will promote novel EMI coatings combined with pitch-based thermally conductive graphite fiber composites. Properties of candidate fibers typically range from less than 3.0 micro ohm-m in electrical resistance with thermal performance exceeding 500 W/mK. The Phase 1 effort will integrate and demonstrate a cost effective EMI coating solution that is partnered with the aforementioned pitch based composite materials. The proposed solution will meet the requirements associated with electromagnetic environmental effects (EEE), shielding, corrosion resistance, and allow for maximum thermal performance. In terms of EMI shielding and ESD grounding of the hybrid enclosure, performance is expected to meet or exceed that of the current aluminum chassis baseline design. Key technologies including coatings, materials, and processes will be demonstrated in Phase 1. The application of EMI coatings will apply to a wide array of DOD and commercial applications. This opportunity will lead to manufacture of a qualifiable working enclosure in Phase 2.

Title:Prognostic Methods for Service Life Management of Digital Electronics
Abstract:We will provide an automated, prognostic decision making tool supporting Autonomic Logistics that predicts when digital electronics will fail to meet service requirements. Incipient fault-to-failure progression characteristics will be identified at the component and subsystem level to develop verifiable prognostic models driven by existing parameters and measurands. We will distinguish between normal equipment aging and slow failure modes. Accurate remaining useful life predictions will be facilitated and enhanced by our modular, open architecture that encourages use of multiple prediction and detection models, yielding highly accurate, timely, extensible, and flexible real-time PHM solutions. False alarms will be reduced significantly using our patented mode partitioning which recognizes distinct operating states and does not alarm when changing between modes. In Phase I, we will develop self-calibrating fault detection models that update dynamically and continuously to individual assets and to changes in individual assets over time. Useful life models and feasibility demonstration prototypes will be developed in the Option Phase with feedback provided by a top-tier JSF contractor. Proven software, system knowledge, and data gained from prior successful PHM USAF SBIR work will enhance and expedite our performance on this NAVAIR project. Self-funded, cost-sharing participation from an industry-leading electronics provider will enhance project success.

Title:Collaborative Multidiscipline Digital Circuit Board Prognostics and Health Management
Abstract:This proposal explores new methods that can improve the ability to accurately predict the useful life remaining for individual digital circuit boards at any particular point in time. The capability proposed herein will improve the system maintainers' ability to identify marginal circuit boards and components, and to replace them prior to their actual failure to ensure their mission is not compromised. Our approach to fulfill this opportunity encompasses new technology that will enable maintainers to visualize both electrical and physical changes within these digital circuit boards that are indicative of pending failure, long before their actual failure in the field. This approach utilizes imaging techniques that span the DC to the EHz range of the electromagnetic spectrum to provide insight into phenomena that can neither be detected nor modeled using today's conventional test program set (TPS) and automatic test equipment (ATE) technology. This technology is highly scaleable and can support extremely complex, densely populated digital circuit boards, and can easily be added to existing and newly developed TPSs and ATE to provide such capabilities in the future.

Title:Prognostics and Health Management (PHM) for Digital Electronics Using Existing Parameters and Measurands
Abstract:In response to SBIR topic N05-093, Impact Technologies proposes to develop and demonstrate an onboard integrated prognostics and health management (PHM) system for aircraft digital electronic boards. The proposed non-invasive PHM system, consisting primarily of advanced software and a minimal sensor array, will be capable of detecting incipient faults, predicting the remaining useful life of critical components, and recommending corrective maintenance actions. This system will integrate collaborative diagnostic and prognostic techniques from engineering disciplines including statistical reliability modeling, damage accumulation models, physics of failure modeling, signal processing and feature extraction, and automated reasoning algorithms. In this approach, cradle-to-grave health state awareness is achieved through the use of model-based assessments in the absence of fault indications, and by updating these model-based assessments with sensed information when it becomes available. Based on this solid foundation of health state information, complementary prognostic techniques including analysis of projected operating conditions by physics-based component damage accumulation/aging models, empirical (trending) models, and system-level failure progression models will be used to develop verifiable prognostic algorithms. The proposed approach, diagnostic techniques, and prognostic models will be demonstrated through seeded fault testing on a relevant commercially available digital electronic board. Only through the utilization of all of these sources of engineering information can the Navy fully realize the PHM concept for digital electronic boards on the JSF.

Title:Enhanced Prognostic Model for Digital Electronics
Abstract:The ability to predict failures in aircraft electronic boards, their digital component elements and devices have the potential to reduce the risks of unanticipated failures while significantly reduce support costs. In this proposal, Intelligent Automation, Inc. (IAI) and Computer Aided Life Cycle Engineering (CALCE) Electronic Products and Systems Center (EPSC) at the University of Maryland propose an enhanced life consumption monitoring methodology for digital electronic boards and their components. Our approach involves a novel process to conduct Life Consumption Monitoring (LCM), including failure modes and mechanisms analysis (FMMA), virtual reliability assessment, sensor data pre-processing/feature selection, fault detection/identification/isolation, stress and damage accumulation analysis, and remaining life estimation. Meanwhile, the prediction output will be associated with a confidence distribution and adjusted by Support Vector Machine (SVM) and Confidence Prediction Neural Network (CPNN). Key advantages include better prediction of Remaining Useful Life than conventional methods, better prediction of some key parameters (thermal cycles and vibration loads) into the future so that prognostics information can be improved, incorporation of a simplified model that can provide "what if" predictions, and a data driven approach to improve the confidence of the overall predictions.

Title:Prognostics and Health Management (PHM) for Digital Electronics Using Existing Parameters and Measurands
Abstract:The identification and development of sensors for monitoring environmental conditions, for detecting incipient faults, and for detecting precursor-to-failure trigger points is one aspect of Prognostic Health Management (PHM) for the Joint Strike Fighter (JSF). Another important aspect is to collect the set of sensor output data and to analyze that set of data using realistic and verifiable prognostic models to arrive at a reliability prediction that can be accurately related to the Remaining Useful Life (RUL) of a part, component, sub-assembly or assembly, such as those found on a Joint Strike Fighter. The objectives of this SBIR are to define techniques and processes to relate RUL predictions to detectable fault conditions; determine the feasibility of developing advanced models and statistical techniques; develop a prototype model/programs for a specific JSF subsystem application and its electronic boards; develop an initial list of required available inputs to the models; outline a method of extracting inputs from a particular subsystem and board; and define user interfaces.

Title:Digital Electronics Health Prognosis
Abstract:Electronic digital circuit boards are composites of organic or inorganic materials with external and internal wiring designed to electrically interconnect and mechanically support all of the components and dissipate heat. Digital electronic circuit failure is ultimately a material failure at either the board, interconnect or component level. VEXTEC proposes to extend JSF prognosis to digital electronics using a physics of failure and material microstructural modeling approach. This project will consider digital circuit failure due to lead-free solder fatigue, board delamination, and individual component failure. The proposed project will develop an innovative, diagnostic/prognostic life prediction methodology for JSF application using currently planned onboard sensed data as modeling input. Phase I will show concept feasibility through a remote input output (RIO) circuit board prognosis demonstration. This system represents an excellent example for the prognosis need given there are ten RIOs at various locations on the JSF aircraft. These ten RIO's represent a system of like components exposed to different environments within the aircraft. Also sensors are currently available to measure temperatures and vibration at each of the ten locations.

Title:Model-based CAHM Software for Dynamic Self-Test of Propulsion Control System Actuators
Abstract:Impact Technologies, in collaboration with our F-35 partners, proposes to develop an embedded health monitoring software package for prognostics and health management (PHM) of propulsion control system actuators using a model-based approach. This approach will feature a detailed dynamic model of the actuator and it's components to detect impending actuation system degradation and faults. The model will be coupled with failure mode diagnostics, advanced knowledge fusion, and failure mode progression (prognostic) algorithms in a probabilistic framework. These proven approaches, along with novel tracking methods, will be developed using available JSF actuator failure mode information and test stand data. In addition, data driven or analytical techniques will also be considered to complement the model-based approach. Model order reduction will be addressed to facilitate on-board implementation and design trade-offs will be evaluated with respect to technical accuracy, required processing, and effects on life-cycle costs. Phase II will strive to the validate the developed software package on available propulsion control actuator data and demonstrate the developed embedded technologies on a JSF test platform through existing contacts. The resulting software will allow dynamic self-test of the actuators to detect incipient degradation in dynamic response of the components.

Title:Embedded Health Monitoring for Propulsion Control System Actuators
Abstract:The latent degradation of precision control system actuators affects dynamic performance and can push the performance characteristics of the actuator out of the regime needed for stable operation of the aircraft control system. Current system-level methods are not sensitive enough to actuator degradation and have no ability to isolate the fault to a specific sub-component or provide an estimate of capability. Sentient Corporation, in cooperation with Pratt & Whitney, will apply subsystem-level performance and fault models to improve fault detection, isolation, and sensitivity for propulsion system actuators. Uncertainty in actuator loading will be reduced by utilizing a load estimator based on engine performance models and augmented with online adaptation algorithms leveraged from the DARPA prognosis program. Phase I will focus on development and demonstration of improved actuator fault and load models. By the end of Phase II, a functional prototype health monitoring system will be demonstrated for a selected JSF propulsion system actuator.

Title:Dynamic Identification of Actuator Frequency Response using Wavelets
Abstract:Current techniques for monitoring actuator performance are inferential, that is, implied via indirect system diagnostics. Results of such methods are neither easily nor accurately interpreted into metrics that can monitor precision and stability of the actuator response. The approach proposed herein identifies the frequency response of an actuator with the Wavelet Eigensystem Realization Algorithm (WERA) method. This proposed technique, originally developed by STI for aeroservoelastic system identification, will use the input and output signals from the actuator, thus offering direct information on its status relative to design specifications and maintenance limits. The technique employs discrete wavelet transforms to compute the impulse response (Markov parameters) of the estimated actuator system. This is then used in the Eigensystem Realization Algorithm to compute the discretized state-space matrices. Metrics are generated assessing the validity of the identified system. Computation is conducted in near real time. The application of the WERA technique will first be assessed via simulation analysis conducted using nominal and off-nominal model representations for propulsion and flight control actuators. A laboratory demonstration of the system identification capabilities will be conducted with exemplar hardware in the loop to evaluate the feasibility of a WERA-based software approach to actuator health monitoring.

Title:Advanced Audio Technologies for Extreme Hearing Protection
Abstract:High noise environments increase the difficulty of face-to-face communication, with or without the use of hearing protection. Further, understanding the sound signals that are available in the environment for maintaining situational awareness becomes more difficult as background noise level increases. It is imperative to provide high-performing hearing protection devices for use in these high levels of noise. Therefore, methods are needed such that face-to-face communications and situational awareness can be restored to the user without causing further increases in the sound power reaching the outer ear. The proposed Phase I program relies on certain features of newly designed hearing protection devices that are reaching final stages of development. Transducers that are capable of offering high speech-to-noise ratios will be used to develop effective means for face-to-face communication between HPD users who are not equipped with radio communications. Specific hardware and algorithm approaches will be selected such that it is possible to monitor safe levels of voice communications and sound source localization delivered inside the HPD. The Phase I program will leverage existing ATI products that already incorporate means for logic decisions and advanced signal processing algorithms.

Title:Hearing Protection Device with Communication for Aviation
Abstract:The military aviation environment experiences very high noise levels often reaching 150 dB. Hearing protection devices for support and maintenance personnel provide inadequate noise protect. In addition, ground personnel usually lack any means of communication other than human voice (shouting). Operational safety is dependent upon flight line crew communication and situational awareness. High noise levels degrade this awareness and affect hearing health which can degrade mission capabilities. Advanced Hearing Products, Inc. (AHP) proposes an innovative approach to protecting personnel from hearing damage while enabling effective voice communications and situational awareness. This Hearing Protection Device with Communication solution is an effective hearing protection headset that compresses high noise to acceptable levels while transmitting voice and environment sound at adjustable amplified levels. Noise exposure levels are recorded and users are passively alerted when daily allowed noise doses are exceeded. The Phase I technical objective is to determine the feasibility of developing the AHP approach for hearing protection in the military aviation environment. AHP will utilize its extensive experience in hearing protection technology and devices to develop the innovative product. AHP has developed and manufactures several hearing protection products with talk-through capability for use in high-noise environments.

Title:Talk Through Noise and Dosimetry System for Carrier Deck Crews
Abstract:Face-to-face communication between crew members launching and recovering aircraft on a carrier deck is impaired by the high-noise environment. High-noise levels also mask the various audio cues that provide situational awareness. Yet effective communication and good situational awareness are key to safe and efficient operations. Current attempts to communicate involve shouting, gesturing, and often lead crewmembers to compromise their hearing protection. Creare proposes a Talk Through Noise (TTN) system that will improve face-to-face communications between crew members wearing hearing protection in high-noise environments, while maintaining the audio cues necessary for situational awareness without degrading their hearing protection. The system also includes a module for speech enhancement that enables communication in very high noise (greater than 110 dB), and a dosimetry module that will allow crew chiefs to effectively manage the exposure of their crews. In Phase I, we will prove the feasibility of our approach through evaluations of potential system components, integration of selected components into a benchtop demonstration, and testing of this system with human subjects in a representative noise field. Prototype systems will then be fabricated and tested in Phase II of the project.

Title:Low Cost Net-to-Shape Fiber Preforms for Complex-Shaped CMCs.
Abstract:As described in Navy SBIR Solicitation N05-096, there exists today a strong need for advanced preforming approaches to produce complex-shaped CMC cooled-turbine components for military engines. MATECH/GSM proposes to address this need by employing innovative low-cost preforming approaches using ""Net-to-Shape""TM non-woven architectures for those CMC components that require high structural performance as well as complex shape formability, such as turbines vanes, blades, and shrouds. MATECH proposes to demonstrate that both requirements can be achieved by the use of non-woven preforming approaches using MATECH's high-performance SiNC fibers combined with MATECH's "Net-to-Shape"TM fiber perform process. These non-woven methods will be demonstrated in CMC preforms and components using MATECH's high-performance Si-doped BN fiber coatings and MATECH's high-performance matrices formed by infiltration and pyrolysis of MATECH's SiNC matrix polymers.

Title:Advanced Preform Technology for Complex-Shaped CMC Cooled Turbine Components
Abstract:CMC components can provide substantial increase in turbine engine performance and fuel economy. However, the current ceramic fibers are not suitable to produce small, intricate shaped reinforcement preforms for turbine components of interest. Reinforcement preform technology has thus become a key bottleneck for development of CMC turbine engine components. This program will demonstrate an affordable technology to produce reinforcement preforms for components such as turbine vane with integral bands. Phase I work will involve fabrication and testing of specimens and a representative turbine demonstration article; to assess feasibility of the proposed technology. Surmet has teamed with a major turbine engine producer. The follow-on Phase II program will refine the reinforcement preform technology and prove repeatability in performance. The Phase II program will also implement this technology in a representative full-scale turbine engine component. The follow-on Phase III program will start activities for insertion of CMC components in military turbine engines.

Title:Uniform Fiber Dispersion Preforming for CMC Turbine Components (1000-734)
Abstract:Triton Systems Inc. (Triton) proposes to demonstrate a solution to practical limitations in available fiber sizes and weave constructions that inhibit effective reinforcement of tight corner and bend radii prevalent in gas turbine hot section components. Through development of silicon carbide fiber molding compounds, engine hardware will have continuous reinforcements that enable reinforcement of thin wall fine geometric details. During the Phase I effort, Triton will define and evaluate molding compound formulations that fulfill mechanical performance requirements while permitting reinforcement of small design features intrinsic to turbine engine hardware. Evaluation will also include densification process development to yield low porosity CMC's. The ability to efficiently reinforce a turbine vane design feature will be included. Projections will be established for manufacturing costs based upon information used and developed in the Phase I. In a Phase II award, Triton will begin the Phase I Option by obtaining high temperature material properties. Also, constituent materials and fabrication processes will be documented to expedite a swift transition towards production. The Phase II activity will select a demonstration component with our engine partner to be fabricated, coated and tested in a realistic engine environment.

Title:Complex-Shaped SiC/SiC Ceramic Matrix Composites via Novel, Non-Woven Preforming
Abstract:The use of ceramic matrix composites (CMCs) has the potential to increase the life and operating envelope of turbine engines. While great strides have been made in mechanical properties, CMCs still suffer from limitations in terms of shape capability, especially with complex-shaped parts such as turbine blades. Using high-strength fibers that have been woven into a fabric causes problems due to the nature of the fabric. The issues of greatest concern with regard to the preform are joining structures perpendicularly to other structures, poor interlaminar shear strength, and creating features with small characteristic dimensions such as wall thickness and radius of curvature. In this project, Ultramet will demonstrate the fabrication of complex-shaped silicon carbide-reinforced silicon carbide matrix (SiC/SiC) CMCs using a novel, non-woven preforming technique. This technique, which will overcome all of the hurdles noted above, will yield near-net shape CMCs with isotropic properties. Mechanical testing of CMCs made from this process will be performed.

Title:Scalable System Approaches to Unmanned Aerial Vehicle Upset Prevention and Recovery
Abstract:Wind shear, icing, wake vortices from ship superstructures or other aircraft, actuator malfunctions, or component failures can all contribute to upset conditions. For piloted aircraft, prevention of or recovery from these events is challenging because of the nonlinear dynamics encountered at angles of attack and sideslip outside of the normal flight envelope. The problems are magnified for unmanned aircraft given typical vehicle sizes, actuator bandwidth, and the absence of a pilot. The goal of our research is to develop the control technologies that enable unmanned aerial vehicles to perform flight-envelope protection and upset recovery autonomously. Reinforcement learning control is a core technology to design outer-loop controllers that affect situation-appropriate recovery within the problem constraints (structural loads, for example). Manual recovery practices and NATOPS procedures are also encoded in the design. Novel control devices can make air vehicles more resistant to departure by postponing the onset of flow separation at high angles of attack. Thus, we address the role of add-on actuators in the recovery control-system framework. These range from a flip-tail for a flight-test UAV to arrays of synthetic jets for a tailless UCAV. High-fidelity simulations of two dynamically dissimilar models are used to develop the technology in Phase I.

Title:Control System Approaches and Experimental Techniques for Unmanned Aerial Vehicle (UAV) Upset Recovery
Abstract:Bihrle Applied Research (Bihrle) has proposed the development of a System for Autonomous Vehicle Recovery (SAVeR) to enhance survivability of unmanned aerial vehicles (UAV). This system will be based on a robust strategy for detecting and suppressing out-of-control motions and implemented using modern control techniques. To accomplish this goal Bihrle will conduct research to assess candidate suppression strategies and control-law schemes. Work in Phase I will also identify and design tools and processes needed to implement and deploy the controller on a modern UAV system. Phase I option efforts will result in a detailed design of the SAVeR prototype to be implemented on a test platform and flown during Phase II. Work during the Phase I option will also yield an engineering simulation of the test platform and systems to be used for further research and development in Phase II.

Title:A Novel Software and Hardware Based UAV Upset Recovery Control System
Abstract:This proposal provides research and development of an autonomous UAV upset recovery control system to enhance survivability during operations outside the normal flight envelope. Unmanned aircraft, like manned aircraft, are susceptible to upsets resulting from aerodynamic disturbances, icing, equipment failures, and/or extreme attitudes due to maneuvering. A novel control architecture for UAV platforms is proposed for development that mimics the response actions of a human operator during a potential upset condition. This outer-loop control combines fault detection algorithms to identify the upset condition with optimal and near-optimal control responses. For cases where sufficient control authority is not available for recovery, innovative shape memory alloy actuators will be developed and integrated into the UAV upset recovery control system. Software tools and test techniques will also be developed during this program to support the design, evaluation, and implementation of the recovery system. For Phase I, initial development of the outer-loop control architecture will be performed and demonstrated through simulation and reduced degree-of-freedom wind tunnel testing. This work will form the foundation for subsequent development, implementation, and evaluation on a generic fixed-wing UAV during the Phase II program.

Title:Low Cost 2D Laminated Ceramic Composites with Improved Interlaminar Strength
Abstract:The objective of this proposed effort is to demonstrate a ceramic composite material having improved interlaminar properties over typical fabric laminates using a commercially available textile process. Affordable fiber preforms using multiple plies of woven CG-Nicalon fabric will be dry-laminated and compacted in a perforated tooling fixture to the requisite fiber volume fraction. The preforms will undergo a thru-thickness needle punching process where a barbed needle will be used to pierce, draw and reorient a small fraction of the fiber in the out-of-plane, "z" direction while serving to mechanically interlock the layers of fabric within the laminate. Needle punching corresponds to the pattern of perforated holes in the preform tooling fixture. The density, or fraction of fiber reoriented in the "z" direction is therefore dependent on the pitch or spacing of these holes where the barbed needle passes. Several laminated preforms will be produced with increasing thru-thickness needling (increasing fractions of "z" fiber reinforcement) and then densified with silicon carbide produced by CVI. Coupon specimens from the various composite systems produced will be evaluated to determine their respective in-plane and interlaminar mechanical properties. These results will be compared to a "baseline" un-needled fabric laminated composite system to establish the overall viability of the proposed approach.

Title:Innovative 2D Ceramic Matrix Composites for Improved Interlaminar Strengths
Abstract:The performance of the JSF can be improved through the use of CMCs because they offer lower weight, improved high temperature strengths, and better performance than existing metal components. Recent tests of CMC components have identified COI's S200 CMC as an attractive material for gas turbine applications. Flight tests of F-16 nozzle components have demonstrated better performance than metal parts. They have also shown that the life of the CMC is limited by the interlaminar strengths. The proposed effort seeks to improve these strengths by assessing three innovative techniques that include 1) an alternate matrix material, 2) stretch broken yarns, and 3) needled preforms. Each of these techniques shows promise based on examination of existing high temperature composite data, which suggest potential strength improvements ranging from two to five times nominal strengths. The proposed Phase I program will be performed by a team of MR&D, Intermat, TEAM, COI Ceramics, and SoRI. MR&D will design the materials, and manage the project. Intermat will stretch break the Nicalon yarns. TEAM will weave the stretch broken fabric and fabricate the needled preform. COI Ceramics will densify three CMCs made with a) alternate matrix materials, b) stretch broken yarns, and c) needled preforms. SoRI will measure the interlaminar shear and inplane tensile properties of each material.

Abstract:3D reinforcement of ceramic matrix composites may have the potential to improve inter-laminar mechanical properties of CMCs, however, the impact on cost to implement the use of 3D woven performs may be high. A novel approach will be taken that will permit the continued use of 2D fabric and standard autoclave molding conditions of a reinforced pre-ceramic polymer matrix. A modified pre-ceramic polymer will be used to prepare composites in this feasibility demonstration. Flexural and shear tests will be run on both enhanced 2D and conventional 2D composites to discern differences in mechanical properties.

Title:Exploration and Evaluation of RTT, TTT, and Hybrid Fusion Architectures
Abstract:In this SBIR Phase I proposal, CleverSet (Prime Contractor and BAESystems (Subcontractor) propose to study Report-to-Track (RTT) and Track-to-Track (TTT) fusion tradeoffs in the context of tactical systems, such as the E-2 and JSF, by developing a testbed for BAE Systems' All-Source Track and ID Fuser (ATIF). The tradeoffs between RTT and TTT fusion are not well understood, and track-to-track fusion systems are generally considered sub-optimal due to the information loss involved in track formation. The proposed work will enable the development of improved RTT and hybrid RTT / TTT fusion algorithms. This will in turn enable more efficient processing and improved performance. Results of the Phase I effort will include an instrumented testbed for controlled experimentation with alternate fusion architectures, an unclassified test-data-suite designed to match the parameters of situations of interest, and initial single-radar study results. Additional results will include a plan for scaling up to more comprehensive, multi-radar and multiple sensor-type experiments, together with a plan for development of optimized algorithms based on the information obtained in these experiments.

Title:Report-to-Track Data Fusion
Abstract:Though data fusion technology has made significant strides in the last few years, combat systems still need a more reliable way to combine and resolve target data from multiple onboard and off-board sensors. Users of data fusion need a way to select among competing data fusion technologies. Additionally, a data fusion algorithm that was developed for a specific problem space may have broader applicability that is difficult to uncover using traditional "solve the problem at hand" acquisition processes. There is no convenient way for customers to evaluate data fusion algorithms from a variety of suppliers or to evaluate data fusion algorithms designed for one environment against a different environment. There is no way to objectively determine "best of breed" across multiple domains. SimVentions proposes the establishment of a Data Fusion Algorithm Simulation, Stimulation, and Evaluation Tool (DF-ASSET) that provides a realistic, repeatable, verified, and validated source of sensor reports to data fusion algorithm(s), and then computes metrics to measure the correctness and performance of the algorithm(s) against ground truth and each other. DF-ASSET is a modular, open, component-based test bed that generates representative sensor data from predefined scenarios, feeding data to a component containing "data fusion algorithm(s)."

Title:Report-to-Track Data Fusion
Abstract:Multisensor data fusion is a critical technology for many Navy missions and platforms. Platforms such as the E-2C, JSF and others require highly reliable tracking and classification of air platforms and ground targets within a tactical region. One critical design decision is the use of report-to-track vs. track-to-track fusion algorithms. In order to evaluate and compare these types of algorithm for varying sensor combinations, a simulation testbed that can readily adapt to different sensor, single-sensor tracker, and sensor fusion models is required. This simulation testbed will be built, using an existing tool, Simulation Framework, and adapting existing models of airborne radar, single-sensor trackers, and sensor-fusion algorithms. This testbed provides the user with a system that is: open architecture, object-oriented, message-based, distributed, reconfigurable, repeatable and expandable.

Title:In-process airflow control of Laser Drilled Small Holes (1000-732)
Abstract:Triton Systems, Inc., in partnership with the General Electric Company's Laser Laboratory and Quality Vision International Inc.'s Optical Gaging Products Division, proposes the concurrent use of multiple sensor types to collect data, which are then processed by an integrated control system to generate a corrective, real-time adjustment to the laser cooling hole drilling process for gas turbine components. The control system will collect data from acoustic, optical, spectral, thermal and positional sensors and imaging devices related to the laser pulse and plasma plume, as well as the cooling hole size, shape and positional coordinates. It will then process and compare the collected data to a data base previously characterized and correlated to targeted airflow values for the turbine component. The comparison will drive an appropriate compensating change in the process parameters to more closely control hole geometry and thus cooling airflow. Tighter control of airflow will result in longer turbine component life, reduced overall production cycle times and costs and gas turbine efficiencies.

Abstract:Beltran proposes an innovative concept for a lightweight, low cost system for effective inlet air filtration or the US Navy's H60 Helicopter. The concetp combines both the inertial and electrostatic particle separation. Electrostatic agglomeration and precipitation is an efficient process for the collection of fine particles and requires low energy consumption for the operation and low pressure loss through the Inlet Filtration System. Our effort will concentrate on development of an electrostatic field in the air inlet, which will enhance the inertial separation of the commonly used Inlet Particle Separators. After mock-up test and evaluation, the most efficient approach will be combined into a final concept design and will be demonstrated.

Abstract:KaZaK Composites will work with Pall Aeropower, a worldwide leader in aircraft filters, to develop and demonstrate next generation helicopter filtration systems that incorporate a new lightweight, low cost, damage-resistant structure in combination with advanced approaches to particulate removal. This team will apply leading edge technology to solve the specific filtration problems outlined in the SBIR solicitation. Phase I will initiate with a careful compilation and evaluation of the military's objectives and requirements for the new filtration system. We will then develop several design approaches that combine different material, configuration and manufacturing technology alternatives, and trade these alternatives against requirements to select an optimal approach. Analytically determined weight and performance predictions will be verified in both the basic and option portions of Phase I. A considerable amount of hardware fabrication and testing will be conducted at in-house facilities of KaZaK and Pall. Phase I will conclude with verified prototype hardware that should provide the government with sufficient confidence in the design to move forward into Phase II. In Phase II the KaZaK team will finalize system designs based on Phase I experience and military comment, and then proceed to fabricate and test full scale hardware.

Title:Low-Cost Thermal Battery
Abstract:Thermal batteries are often the battery of choice when very long shelf life is needed, and accessibility to the battery is limited. Improvements are sought for achieving improved electrochemical performance, lower cost, and building batteries in conformal shapes. Unfortunately, present manufacturing processes make it difficult to meet these goals. The purpose of this proposed work is to make lower cost, high performance thermal batteries through the use of improved, continuous processing of battery components. Batteries will be made using any of several techniques, including the incorporation of a binder, spray processing, tape-casting, and an innovative lamination process. In doing so, continuous processes will replace the lengthy and costly batch processing presently used to make rigid thermal batteries. All of the processes allow for more optimum sizing of electrodes and other cell components,that will improve performance. Furthermore, batteries will be made that can fit into non-standard spaces, such as curvilinear shapes. Phase I will be devoted to demonstrating high volume, low cost processes, and the demonstration of five cell, 3 Ahr cells, especially their power output throughout an extended discharge. During Phase II, 56 V stacks will be engineered and demonstrated, including battery containers and other associated support components.

Abstract:This proposal provides for the development of low-cost thermal batteries through the use of novel and unconventional methods for electrode fabrication that should drastically reduce the cost of thermal batteries and dramatically improve performance. Preliminary tests have been carried out to show the feasibility of the preparation of the cathode electrode by painting. The capacity of the cell with the painted electrode was better than the standard PP cell. The cell also showed lower polarization during phased transitions due to improved mechanical bonding between cathode particles. The data presented substantiates the contention that painted electrodes offer equivalent performance as standard PP electrodes but at a much lower cost. Work is needed to optimize the spraying conditions to achieve higher throughput and equivalent electrochemical performance in full-sized batteries. Tasks are delineated to achieve these goals.

Abstract:A direct-drive electric linear actuator for raising and lowering the jet blast deflector (JBD) is proposed that achieves the specific force necessary to be a form-fit-function replacement for the existing JBD hydraulic actuators. Moreover, we propose a design that is suited to modularity, allowing the actuator to be readily scaled to meet the requirements for other Navy shipboard applications. Successful replacement of all of these hydraulic actuators with electric actuators would allow the elimination of the entire catapult hydraulic system. A building block actuator and the associated power and control electronics will be designed during Phase I. In addition to the theoretical design work aimed at meeting fundamental performance requirements, attention will be paid to manufacturability, cost, reliability, maintainability, and operational features such as braking and cleanliness. During Phase II, construction and test of a single building block will be followed by prototypes with increasing capability until full-scale performance is achieved. The prototypes will demonstrate performance (force, stroke and speed) as well as maintainability and reliability of the actuator system. The Phase II design will be reworked during Phase III to produce a full-scale system JBD actuator to be installed and tested under realistic environmental and operational scenarios aboard a carrier.

Title:Dynamic Decision Support (D2S) for Real-Time Assessment of System Health and Fault Contingency Planning
Abstract:Impact Technologies, in collaboration with Honeywell Engines and Systems, propose to develop an innovative Dynamic Decision Support (D2S) concept for critical aircraft systems using simulation-based fault classifiers and adaptive contingency management techniques, which will be implemented through a real-time software agent architecture. The significant technology advancement proposed herein is based on using dynamic model simulations in a real-time computing environment to not only diagnose faults, but also to determine "on the fly" how accommodate for them. Current on-board technologies have to map fault conditions to an associated set of pre-determined contingency plans, which can not possibly account for the entire set of fault scenarios that can occur in flight. Hence, the innovations of this project include: 1) Development and demonstration of an agent-based software architecture that is capable of executing simulation models of critical aircraft systems with an adaptive flight control component that performs fault contingency management in real-time; 2) Develop simulation-based fault classification algorithms for the Honeywell Power Thermal Management System (PTMS) with real-time functionality in all system operating modes; 3) Develop contingency management algorithms using dynamic performance assessment calculations and flight control command generation under faulty aircraft system dynamics constraints; and 4) Develop a Simulink-based demonstration of the dynamic contingency management and fault-adaptive control system with application to the Honeywell PTMS.

Abstract:The Joint Strike Fighter (JSF) engine will be capable of performing on-board fault detection, isolation, and prognosis. Current processing relies on BIT codes generated by the engine control system. These BIT codes are derived from steady state engine performance and do not address the prognostics problem.

IAC, with Pratt & Whitney support, proposes to develop a dynamic simulation-based turbine engine model for maintenance decision support. This model-based approach will provide: 1) accurate assessments of gas path rotating machinery deterioration, 2) in-range fault coverage of control system sensors, and 3) a system-wide assessment of engine health status. The fundamental components of the proposed prognostics system are generic. In Phase 1, IAC will specify the requirements for implementing the gas path prognostics system for the F135 application. Given the availability of F135 engine data, the algorithms will be coded and demonstrated in the MATLAB/Simulink environment. In lieu of F135 data, a PW6000 engine will be substituted for the proposed prognostics system demonstration.

Title:Effective Diagnostics for Dynamic Operating Environments
Abstract:Fault detection and isolation algorithms are often developed with data from steady-state tests, and many algorithms perform well under these controlled conditions. However, when diagnostics are used in highly dynamic environments, sensitivities to changing loads or speeds become apparent. Vibration metrics tend to be particularly susceptible to operating condition variations. This sensitivity interferes with effective diagnosis and requires fault thresholds to be increased significantly to avoid false alarms, making the system less sensitive to real problems. Sentient Corporation, in cooperation with Pratt & Whitney, will develop new vibration diagnostics for dynamic environments that leverage existing physics-based models for fault induced vibration. These new algorithms will greatly enhance diagnostic performance in dynamic operating environments and will also improve fault severity indication for steady state applications. These new techniques will be developed for and demonstrated on a highly dynamic F-135 subsystem such as the lift fan drive. During Phase I, a functional proof-of-concept system will be implemented and tested using bearing seeded fault data collected under dynamic conditions.

Title:Low Cost Si-BN interface Coatings for SiC/SiNC CMCs.
Abstract:MATECH GSM proposes to develop a low cost, uniform, reproducible Si-doped BN interface coating process for 3-D and 2-D woven ceramic fiber preforms. Using MATECH's new Reactive Transformation Process (RTP), Si-doped BN interface coatings will be demonstrated on woven SiC ceramic fiber performs without fiber-to-fiber bonding. Key parameters to be investigated will include: 1) Control of interface coating thickness, chemistry, and crystallinity, 2) Uniformity of interface coating thickness and composition, 3) Batch-to-batch reproducibility, 4) Retention of as-received ceramic fiber strength, and 5) Mechanical properties of fully densified SiNC-CMC coupons with RTP-derived Si-doped BN interface coatings. The current "state-of-the-art" process for producing BN inter-phase is chemical vapor infiltration (CVI). One drawback of the CVI BN process is that when a tow (500 to 800 fibers) is formed into a woven fiber preform prior to BN coating, many of the fibers are in contact with each other and therefore do not become completely coated. On subsequent fracture of the composite, those fibers that are in contact with no BN between them tend to fail in a brittle manner, little or no fiber pullout. The RTP coating mitigates these issues.

Title:Low-Cost, Low-Temperature Deposition of Fiber Interface Coatings
Abstract:Conventional fiber-matrix interface coatings applied by chemical vapor infiltration (CVI) are expensive because they require costly, high-temperature equipment and must be applied at a slow rate in order to achieve uniform infiltration across large thermal gradients. In previous work for DoD and NASA, Ultramet developed a rapid, low-cost method of applying oxide and carbide interface coatings to carbon and silicon carbide fibers at low temperature (as low as 100C) through ultraviolet-enhanced chemical vapor deposition (UVCVD). UV energy is used to decompose coating precursor gases at much lower temperatures than when thermal energy is used alone. The low temperature process virtually eliminates the fiber degradation that inherently occurs during conventional high-temperature CVI. Interface coatings have been applied to fiber tows as well as woven and braided structures, and were subsequently infiltrated with various carbide matrix materials through a novel melt-infiltration process. Ceramic matrix materials formed through melt processing do not exhibit the extensive microcracking that is common in most matrix materials. The very low microcracking improves interlaminar shear strength and substantially reduces the transfer of moisture and combustion gases into the composite, thereby further protecting the fiber reinforcement. Composite components in the form of thrust chambers and flat panels have demonstrated good mechanical and chemical survivability during high temperature hot-fire testing. In Phase I, Ultramet will develop UVCVD processing for rapid and low-cost application of a silicon-doped boron nitride coating, similar to that applied at high temperature, to silicon carbide fiber tows and panel preforms. Mechanical testing of composite panels will be performed before and after high-temperature oxidation testing in accordance with requirements defined for the Joint Strike Fighter aircraft. A cost comparison will be established between UVCVD coatings and those produced by conventional CVI. In Phase II, Ultramet will team with Lockheed Martin to establish a melt-infiltrated CMC property database, produce and test subscale components in conjunction with the Navy and Lockheed Martin, and demonstrate scaleup potential.

Abstract:The purpose of this project is to demonstrate the effectiveness of using a conductive, wear resistant coating to improve the lifetime and reliability of slip rings, in particular the slip ring system used in the V-22 Osprey. Acree Technologies Incorporated has developed an innovative, conductive coating that is exceptionally hard, smooth and wear resistant and has a low coefficient of friction. This coating has been shown in previous tests to improve the lifetime of surfaces in sliding contact by greater than five times. Preliminary sliding contact tests have shown that the electrical noise of a coated slip ring is less than 10 mohm, exceeding military specifications.

Title: Innovative and Affordable Materials/Concepts for Improving Rotorcraft Slip Ring Reliability
Abstract:Diamond Antenna proposes to use Roll-Ringr technology and create a form, fit, and function Roll-Ringr replacement for the V22 slip ring. Unlike slip rings with a sliding electrical interface, Roll-Ringsr employ a rolling, non-sliding, electrical interface. The rolling, non-sliding, interface is a non-wearing, metal-to-metal, electrical interface that does not generate wear particles. Because there is virtually no wear, the Roll-Ringr will meet the 10,000-hour operating requirement and the 3000-hour MTBF requirement. Testing to date shows that Roll-Ringsr without maintenance will surpass the V22 life by 40%. In addition, because there is no wear or debris, the Roll-Ringr maintains its electrical characteristics over the life of the product. The Roll-Ringr has the following advantages over slip rings that use brush blocks. 1. No maintenance 2. Long life 3. Consistent electrical parameters throughout the life of the product 4. Low resistance 5. Low noise, i.e. low variation in circuit resistance due to rotation

Title:An Adaptive Geographic Internet Sub-Protocol for Dynamic Wireless Networks
Abstract:In order to seamlessly integrate ad hoc and sensor networks with the Internet, we introduce a novel entity called Internet Sub-protocol Manager (ISM) that serves as the "bridge" between the standard IP and our geographic sub-protocol (SP). The standard IP stack (either IPv4 or IPv6) needs not to be changed. Rather, the ISM will encapsulate the original IP packets within the sub-protocol payload and provide an IP-in-SP tunneling. The sub-protocol exploits the geographical and mobility information available from the GPS equipped communication node and achieves position-based routing that incurs less storage and less processing overhead. The geographic routing provides alternate paths for such wireless nodes. While current geographic routing protocols are impractical, our proposed Cross Link Detection Protocol (CLDP) guarantees that geographic routing between all pairs of nodes will never fail. We have demonstrated that our approach achieves geographic routing correctly on real radio networks. ISM and our geographic routing protocol can be easily configured and we provide an efficient mechanism for wireless routing packet format discovery. In addition, we propose to adaptively manage the routes via proactive prediction of link expiration time and describe a method for differentiating link failure and congestion.

Title:Configurable Internet Sub-Protocol for Sensor Networks and State Space Aware Adaptive Routing
Abstract:The migration of MANET protocols to networks supporting fast movers has been problematic, due to the network dynamics caused by fast moving aircraft in the network. The amount of overhead traffic required to maintain connectivity in these networks is often intolerable. Nova proposes two methods for reducing the network overhead burden. First, a communications extension for efficient distribution of small network packets will be developed under this effort. The protocol will be designed as a portable software module, which is seamlessly inserted between the network routing and wireless interface driver. With this software component, each node will have the capability to dynamically negotiate the use of a subchannel over standard IP, while still retaining full support for the distribution of IPv4/IPv6 messages. To reduce the raw amount of network overhead required, Nova also proposes technologies that will equip each node with a better sense of its location and role in a network. This will be facilitated by the exchange of position, velocity, and time information around the network, and by passive sensing of link quality through advanced cross-layer techniques. Both technologies are proposed as extensions to IETF standard protocols, which will ensure the viability of these technologies' deployment and acceptance.

Title:Adaptive Interface for Management of Bias and Workload Reduction (AMBR)
Abstract:Advances in aircraft performance and weapons capability have led to a dramatic increase in the tempo of tactical situations facing the combat aviator or UAV controller, reducing the operator's available information processing and decision-making time and resources. Furthermore, the technological and information advances of Network Centric Warfare (NCW) have resulted in an explosion in the complexity and sheer quantity of information that is available to the operator. To counter this increasingly complex operational environment, the Navy requires advanced human/system interface concepts that will make optimal use of the operator's cognitive resources and minimize potential for operator error. The adaptive interface should enhance the flow of information and control between the operator and the vehicle to improve the operator's situation awareness (SA) and decision-making performance while alleviating workload and reducing the effects of cognitive biases, and thus improving survivability, lethality, and ultimately, mission effectiveness. To address this need, we propose to develop a prototype Adaptive Interface for Management of Bias and Workload Reduction (AMBR) that uses computational SA models, operator mental and physical state tracking, and cognitive bias tracking to drive the content, format, and modality of military displays for operation of advanced aviation systems.

Title:Enhancing Warfighter Performance through Predictive Model-Based Decision Aids and Adaptive Displays
Abstract:The objective of the SBIR topic is the development of adaptive displays and decision aids that optimize operator/team performance by dynamically capturing and using real-world information more accurately. We intend to address this need by applying fuzzy signal detection theory, or FSDT (Hancock, Masalonis, & Parasuraman, 2000) to the domain of adaptive displays and decision aids. We propose in the Phase I research to develop specifications for a prototype system to measure, predict, and enhance pilot performance: the Fuzzy Signal Decision Enhancement System (FEDES). In Phase I, the FEDES will focus on a simulated targeting task, in the context of friend/foe discrimination. FEDES will integrate information regarding multiple dimensions of ongoing mission activity and real-world variables; thus, FEDES will address the effects of multiple factors on performance. Based on ongoing assessment of pilot performance, FEDES will change the organization of the information presented to the pilot to enhance pilot performance. FEDES will track pilot performance over time with high temporal resolution (i.e., over the course of seconds, rather than minutes or hours).

Abstract:This solicitation calls for exploration and development on approaches to find solutions to innovative, high power, short pulsed, low cost W-band transmitters. The approach to be undertaken in this SBIR proposal by InnoSys is to develop a compact, small volume, low-cost, high-power W-band solid state vacuum device (SSVD) transmitter specifically designed for this SBIR program. Design goals include initially developing a compact 50-watt peak radio frequency (RF) output power, chirped solid state vacuum device W-Band pulsed transmitter that matches a 30:1 compressive filter response and can produce chirped pulses of several hundred nanoseconds at a pulse repetition frequency (PRF) of several hundred kilohertz. Later designs and iterations of this SSVD W-band pulsed transmitter should be capable of providing significantly higher peak power levels, PRF and duty cycle operation if needed.

Title:W-Band High-Power Chirped Solid-State Transmitter
Abstract:By capitalizing the high power capability of the W-band series stacked pulsed IMPATT diodes, and a hybrid-coupled combiner, pulse power output greater than 50 watts can be achieved from a transmitter, more than twice the output power currently achieved from a single junction device, but small enough to be gimbal mounted. Injection locking the combiner to the pulsed frequency chirping IMPATT oscillator currently used in HARM development, the high output power will have the necessary pulse compression characteristics of the locking oscillator. The higher power output will enable the HARM to have longer range and more robust performance.

Title:Orientation Invariant Combat Identification
Abstract:A primary mission of Naval air assets is to detect and destroy enemy ground targets. In order to accomplish this mission, the weapon systems must be able to detect and classify potential targets to determine which are valid targets. Traditional combat identification has been performed using all weather sensors and processing algorithms designed specifically for such sensor data. Newer electro-optical (EO) sensors produce a very different type of data that does not lend itself to the traditional combat identification algorithms. Therefore, there is a need for new algorithms to perform combat identification within EO data. Cybernet proposes to leverage our existing pose determination system to create algorithms for performing combat identification of targets within EO sensor data at any orientation. The system uses feature data (typically object edge data) and a target database to determine the 3D position and orientation of the object and the object's identity. The system stores a very compressed representation of the target for comparison purposes. This allows target information to be shared easily of networked resources.

Title:Electro-Optic (EO) Feature-Based Target Combat Identification (CID)
Abstract:We propose to design, develop and evaluate a deterministic approach to combat identification (CID) of stationary and moving objects using a single video stream. From a video containing a moving target, we detect and track the target using an appearance-based tracker. Stationary targets in the video are extracted using a shape-driven operator. Using fingerprints extracted from the segmented target chip and synthesized views of targets generated from a homgraphy derived from the given video sequence, quasi-invariants and a generalized Hausdorff metric, we design a target CID algorithm. A special case of our algorithm handles the target CID problem for stationary targets. Using the results of target segmentation, we will develop an efficient compression scheme for transmitting the target chip over noisy channels. During Phase I, we will assess the potential performance of a stationary and motion-based video CID capability by integrating a suite of algorithms for the tasks mentioned above. The resulting working software prototype will help us to identify challenges to be addressed during Phase II. During Phase II, we will demonstrate and evaluate a prototype system capable of robust verification/identification in video imagery. Our goal is to sue as few a frames as possible in determining CID.

Title:Robust Airborne Combat Identification using Scale-Invariant Spatial and Spectral Electro-Optic Signatures
Abstract:Electro-optic (EO) imagery provides a rich source of information for feature-based target combat identification (CID). Yet, variable operating conditions, including sensor range, depression angle, and angle of approach, as well as target illumination and degree of occlusion, have so far prevented the development and effective deployment of a complete solution for real-time airborne CID. While much attention has been devoted to discovering target features which are invariant to orientation and affine view transformation, the resulting features have proven to be insufficiently discriminatory for large model databases. To address these and other challenges, we propose the use of scale- and affine transformation-invariant spatial and intensity features, combined with color/spectral histogram features, for robust, high-performance CID. Furthermore, we show how real-time airborne processing capability can be achieved through efficient candidate target segmentation followed by a hierarchical classification structure. This framework ensures that the most computationally demanding operations are only performed for a small number of most likely candidate target matches. Throughout, we show how storage and bandwidth requirements can be minimized, to enable deployment of the complete CID system on the F/A-18E/F and a variety of other platforms, leading to reduced operator workload and improved combat effectiveness.

Title:ContentVault T: Methodology and Tools for Securing Training Objects and Records
Abstract:With the need for learning objects to be shared, reused, referenced, and repurposed by a variety of geographically-dispersed stakeholders, it is imperative to provide access control, authentication and identify management services within Learning Management Systems (LMS) and Learning Content Management Systems (LCMS). In particular, these requirements need to be satisfied by the Navy's Integrated Learning Environment (ILE) which comprises both a LMS and a LCMS. The problem today is that introducing authentication and authorization approaches within a single LMS or LCMS product cannot produce a scalable solution that applies to distributed learning environments that typically contain products from multiple vendors. To this end, this project will develop a standard framework that would allow the enterprise authentication management infrastructure (AMI) to be deployed in an efficient fashion to protect training assets and records and facilitate their audit. Phase I of this effort will establish the feasibility of applying standardized tokens to SCORM-compliant training packages and determine the access control and security scripting techniques needed for legacy DoD training programs as well as for new distributed learning programs.

Title:Securing Training Objects and Records Management
Abstract:Delivery of training materials via the Web is rapidly becoming an essential method of delivering training in an efficient and cost-effective manner, both in the military and civilian environments. Widely dispersed training audiences, however, require various levels of access control to training materials, particularly with respect to sensitive training materials or high-stakes testing/training scenarios. Although authentication tokens such as smart cards and biometrics can provide stronger authentication, access control, and audit trail logging, at this point there is no standardized way to integrate strong authentication tokens with the Learning Management Systems that are used to manage, track, and deliver Web-based distributed training. This proposal addresses two challenges of securing Web-based distributed training content: The first is to determine the feasibility of integrating strong authentication and access-control tokens, in a standardized manner, to SCORM-compliant training packages, as launched and tracked by a Learning Management System (LMS). The second challenge is to assess the strong access-control needs of current Department of Defense distributed training programs and thereby determine the access-control requirements for current and future advanced distributed training activities.

Title:Precision Targeting for the Tomahawk Cruise Missile Using Miniature Unmanned Aerial Vehicle (UAV) Sensor Data
Abstract:The use of tactical miniature unmanned aerial vehicles (MAV) is on the rise. MAV systems are typically affordable and small enough so that they can be operated at the platoon level and used to extend a unit's "line-of-sight" to see over/around mountains or into urban canyons. In the near future it is envisioned that the sensor data collected by tactical MAVs will be part of the Navy's FORCEnet intelligence, surveillance, and reconnaissance (ISR) system. Thus, the potential will soon exist to combine the data collected from any number of MAVs to produce accurate targeting information. By combining this network of tactical MAVs and the loiter and in-flight targeting capabilities of the Block IV Tomahawk cruse missile an opportunity exists to develop a new weapon system that combines persistent ISR, targeting, and strike of time critical targets. The ISL/Raytheon team envisions a system for which a user located anywhere in the world can analyze MAV sensor data provided over the FORCEnet to track, identify and strike high value and time critical enemy targets.

Title:Precise Targeting of Tomahawk Cruise Missile Using Low-Cost, Low-Quality Miniature Unmanned Aerial Vehicle (UAV) Sensor Data
Abstract:We propose methodologies for using Miniature unmanned Air Vehicle (MAV) sensor data to enhance Tomahawk Land Attack Missile (TLAM) targeting. Our approach uses 3D contextual information of the area available from existing DOD databases to determine MAV sensor pose. Optimization is performed to refine the camera orientation to improve pose accuracy. For relatively flat targets, the 3D world coordinates of a target selected in the 2D imagery are determined using the projection properties of the sensor. For targets with significant elevation, multi view processing is performed to determine accurate 3D positioning. We demonstrate additional capabilities for accurate targeting without pre-existing 3D models when GPS and IMU data are available. Error bounds relating the required system resolution and control point accuracy to targeting position estimation accuracy will be quantified. During Phase I, we will build on our past work on image to 3D registration to provide reliable targeting from videos acquired by MAVs. Phase II efforts will focus on developing a prototype of the proposed system.

Title:Self-Contained, Miniaturized, Robust, High-Speed Fiber Bragg Grating Sensor Interrogator
Abstract:Safety and reliability of ordnance, such as that in solid rocket motors, requires determination of system integrity. To achieve this, a need exists for embedded sensors to provide real-time high-speed indication of system health. Optical Fiber Bragg Grating (FBG) sensors are the most promising types of sensors for dynamic strain measurements due to their light weight, small size, immunity to electromagnetic interference and multiplexibility. However, commercial FBG sensor interrogators are too heavy and large to be deployed in such applications. Based on years of experience and innovations in FBG sensor systems, IFOS proposes a novel miniaturized FBG sensor interrogator with low power consumption to be incorporated into tactical solid fuel rocket motors. It will be capable of interrogating a single optical fiber containing well over five sensors based on commercially available FBGs, under 0.25 pounds in weight and 5 cubic inches in volume, involving no moving parts. The interrogator will operate over the C (extendable to C+L) wavelength band(s), with resolution of 1 pm, dynamic range of 4000+ microstrain per sensor and speed over 5 kHz per sensor. Implementation will be primarily based on well-tested long-lifetime and highly reliable commercially available components.

Title:Low-Cost Field-Installable Fiber Optic Cable Restoration (post splicing)
Abstract:Splicing of fiber optic cable in military platforms as a means of repair is highly desirable to eliminate the expensive and time-consuming task of cable replacement. Since no qualified splicing device or technique exists today, development activities are ongoing for a field installable fiber optic splice for DoD applications to solve this growing maintenance problem. However, the splice device is only half the solution. Military applications utilize robust cable constructions with multi layers and strong embedded tensile members, such as Kevlar, to protect the fragile fiber. In order to install any splice device, the cable construction is breached and must be repaired. This proposal address a means to restore the fiber cable to an almost virgin state with minimal degradation is it mechanical integrity and at the same time protect the delicate splice. Furthermore, a tool set for installation is proposed such that installation by servicemen is quick and easy to perform in adverse conditions that exist in the field.

Abstract:The operational commitments required of today's Navy as well as the goal to streamline material resources have made it necessary to increase maintenance quality while reducing time spent in its performance. Novel methods are being employed to reduce cost, time, and improve the mission readiness of military aircraft. Commonly, repairs made to the fiber optic networks on Navy aircraft at sea, require for optical cable to be spliced. The ability to mechanically restore the spliced section of cable back to its original specifications will reduce future maintenance costs while improving mission readiness. Luna Innovations is proposing to develop and manufacture low cost, transparent cable restoration devices and tooling that will fully restore the mechanical properties of the cabling after the splicing has been preformed on the optical network. During the first phase of this three phase development program, Luna will design, model, manufacture and test prototype devices to prove design and material feasibility. The Phase II effort will consist of design optimization, extreme environmental testing, and a sound plan for transition to large scale manufacturing. This project will result in a device and its necessary tooling that will meet the needs of the Navy for optical and electrical cable restoration.

Title:Low-Cost Field-Installable Fiber Optic Cable Restoration (post splicing)
Abstract:Fiber optic cables are increasingly being used for advanced avionics on aircraft such as the U.S. Navy and Marine Corps F/A-18E/F Super Hornet. Innovative repair techniques and materials are needed for restoration of fiber optic cables that become fractured or severed during operations. Matching the original strength and durability of the fiber optic cable will be required. This will be achieved through the use of a new class of fluorinated elastomers for encapsulation of the reinforced repair section. Innovative reinforcement materials will also be employed. Current simplex cable jackets are typically composed of fluorinated thermoplastics such as FEP or ETFE, which have outstanding moisture and chemical resistance. The new splice system will be designed to withstand the full range of environmental exposures that are encountered by military aircraft. These include extreme temperature and humidity, salt spray, particulate, and pressure cycling. An additional issue that will be addressed is related to the amount of space that repair technicians are confined to when making repairs. The developed systems will be required to be adaptable to these confined space repair scenarios. Also, no specialized equipment will be appropriate for field repair situations, and this constraint will also be addressed during Phase I.

Title:Fleet-Wide Variability for an Integrated Flight and Propulsion System
Abstract:Impact Technologies, LLC, in collaboration with Pratt & Whitney and Pennsylvania State University proposes the development and validation of a software tool for the analysis of robustness and performance of integrated flight and propulsion control systems. This tool will enable automated analysis of the system along with its parametric and non-parametric variability to quantify system stability margins, as well as time and frequency domain performance. During the analysis, it will quantify and incorporate variability and uncertainty in dynamic performance and control. This uncertainty characterization process will account for variability in the target platform during its useful life and across an entire fleet. This tool will draw upon techniques from multivariable robust controls, nonlinear system analysis, probability and nonlinear programming. It will also characterize the effect of variability on service life and fault progression. It will represent a significant improvement in computational, time and cost saving over more cumbersome and less robust state-of-the-art techniques like Monte Carlo simulation. The primary target platform of this tool is the Joint Strike Fighter (JSF) propulsion system. During Phase I, Impact will work with Pratt & Whitney to develop and demonstrate this tool on a PC in Matlab/Simulink, using a generic engine and engine control model. Impact will also characterize the performance of this tool against state-of-the-art techniques. Phase II will expand this tool to enable analysis on the JSF integrated flight and propulsion control system. Phase III will enable migration to other engines, land based turbines, aeronautic and astronautic platforms.

Title:Fleet-Wide Variability for an Integrated Flight and Propulsion System
Abstract:This Small Business Innovations Research Phase I project proposes a product development effort aimed at establishing procedures and software tools for quantifying the impact of component dynamic performance variability across a fleet of Integrated Flight and Propulsion Control systems (IFPC). We propose a set of innovative tools to guarantee dynamic performance, for full life, across a fleet of aircraft. The innovative feature of the proposed methods is that a few experiments or high-fidelity simulations are carried out on a small subset of a large number of propulsion controllers and the nearby controllers are validated or rejected using much simpler simulations. The performance criteria for variability analysis include thrust, stability margins, and failures. The evaluation will demonstrate the analytical feasibility assessment for a representative complex high bandwidth propulsion control problem. In Phase I, the developed techniques will be applied to a Short Takeoff and Vertical Landing (STOVL) example. Prototype validation algorithms will be developed in an industrial software environment. In Phase II, technology developed at SC Solutions and UCSD will be made into a prototype software product and will be demonstrated on a problem that can be scaled to a full-sized IFPC system. The potential for wide-ranging commercial applications is very significant since we will be developing the first-ever commercially available validation tool.

Title:Radar Centroid Processing Algorithm with Tracker Feedback
Abstract:The raw detection data provided by a radar typically consists of primitive measurements that correspond to discrete range-bearing cells. A single target can generate multiple primitive detections in adjacent range-bearing cells as the radar beam scans across it; the radar system therefore employs a centroid processing algorithm to combine the primitive measurements and form a single merged detection report to pass along to the tracker. However, if multiple targets exist close to one another, this clustering process can produce undesirable results such as track degradation and/or track drop, since the measurements for more than one target may be combined to produce a single report. Here, we propose a method for utilizing feedback from the tracker to produce the appropriate number of centroid estimates in a given area, thus avoiding track drop. Our method is a modification of the Expectation-Maximization algorithm as applied to the Gaussian Mixture Estimation problem; accordingly, we will refer to our algorithm as EMARCT (an Expectation Maximization Algorithm for Radar Centroid processing with Tracker feedback). In Phase I we will develop the algorithm in greater detail, program it in a high-level language such as matlab, and demonstrate its feasibility on simulated data.

Title:Radar Centroid Processing Algorithm with Tracker Feedback
Abstract:In surveillance platforms such as the E-2C and upcoming E-2D, it is essential that the Airborne Early Warning (AEW) radar provide a complete track picture of the surveillance region. To maintain continuous tracks throughout the surveillance region, the radar sensor must be able to produce measurements on all targets. Problems occur when there are closely spaced objects (CSOs). Here, the radar signal processor can combine the returns from the targets to produce a single merged measurement. The objective in the proposed research is to develop a new surveillance radar centroid processing algorithm that has an extended merged measurement capability. The algorithm will "parse" the raw range-bearing cell measurements such that object measurements for each target can be generated. The use of tracker feedback enables the processing algorithm to specify the expected number of objects within the combined cluster of measurement primitives. The work will leverage Numerica's prior experience in radar centroid processing and pixel-cluster decomposition research.

Title:High Altitude Non-Acoustic Antisubmarine Warfare (ASW)
Abstract:Intevac proposes to develop an Intensified Photodiode (IPD) which can be gated on and off very quickly with relatively low voltage. This gated IPD would be an ideal detector for laser pulse reflections from ship or airborne lasers used for probing for objects in sea water. Gating the detector on for only the time periods when reflections could be received from possible objects of interest greatly extends detector lifetime and reduces noise, thus increasing object detectability. Intevac produces an IPD which, as presently designed, cannot be easily gated. We propose to investigate design of an IPD to permit high speed, low voltage gating and extend lifetimes. Phase 1 is a design study of a technical approach which could be successful with minimum additional tube complexity and cost. A Phase 1 Option is the exploration of a grid structure in the IPD if the initial investigation concludes that it is necessary or desirable.

Title:Photonic Crystal Filter for ASW Operations
Abstract:MetroLaser proposes to design and build an innovative ultra-narrow high throughput optical bandpass filter based on the properties of a dielectric photonic crystal structure with a resonant cavity. Such a structure can exhibit an ultra-narrow high-transmission band in the middle of a wide low-transmission stop-band. During Phase I, we will demonstrate experimentally the proof-of-concept for a filter with sub-nm bandpass, high throughput and rejection level in both visible and infrared (IR) regions. We will also develop a complete model of the functional characteristics, based on specific features of photonic crystal structures with a resonant cavity, and develop a strategy for building a prototype of the instrument. The proposed filter is expected to have a bandpass range of 0.1 nm, an acceptance angle of 2,a and an aperture of about 10 inches. During Phase II, a rugged version of the filter will be demonstrated. A compact, low-weight, single-assembly design of the filter will allow it to be retrofitted to existing instruments and provide a stable performance in harsh operating environments.

Title:Wide Field of View Narrowband Holographic Grating Array for Improved Spectral Filtering in High Altitude Antisubmarine Warfare Systems
Abstract:RL Associates Inc. proposes to conduct a feasibility study leading to the development of a narrowband, wide field of view, volume holographic filter for high altitude Light Detection and Ranging (LIDAR) systems used in antisubmarine warfare (ASW). We propose a filter element composed of many individual volume holographic gratings, spatially separated to form an array, and arranged in such a way that their narrow individual fields of view complement each other to produce a wide field of view for the entire element. This new type of spectral filter composed of an array of volume holographic gratings can be tailored to a broad acceptance angle while maintaining extremely narrow spectral bandpass of 1 or less. Diffraction efficiency of greater than 60% has been demonstrated by RL Associates in previous volume holographic filter work.

Title:Nondestructive Measurements of Cold-Working Zones at Fastener Holes
Abstract:In the aerospace industry, a fastener hole is considered as potential crack initiation site for structures that undergo cyclic fatigue loading because of the stress and strain concentration. However, the use of a cold expansion process to introduce a compressive residual stress field in the material surrounding the hole can enhance the service life of stressed aerospace components. Unfortunately, no method exists to quantitatively assess the effectiveness of the process. Use of the wrong expansion tool, out-of-round holes, and other factors can reduce the effectiveness of the process. Luna Innovations will develop a practical portable ultrasonic instrument capable of assessing changes in residual stress near aircraft fastener holes. The device will indicate both stress gradients and direction. This new instrument will be designed for use in the field by qualified inspectors without a high degree of training. The basis of the device is the small change that occurs in sound velocity in a metal under stress. Although this phenomenon has been understood for several decades, no company has achieved a practical device for fastener hole residual stress assessment. Luna has the capability to create such a device that can meet the Navy requirements including that of low cost and portability.

Title:Nondestructive Measurement of Cold-Working Effectiveness at Fastener Holes
Abstract:Fatigue properties of aerospace structures are improved significantly by the application of cold-working processes, which impart favorable compressive residual stresses at and near the surface of the metal. While cold-working production processes are tightly controlled to ensure the effectiveness of the process, human errors are known to occur and the degree of fatigue or damage resistance may be less than the design requirements. Today, no means exists to non-destructively measure the residual stress state of cold-worked fastener holes. Proto has years of experience in measuring the effects of surface enhancement techniques and believes that x-ray diffraction (XRD) technology can provide the NDI capability needed by the USN. Proto intends to prove that XRD is a feasible and cost-effective solution for the challenge posed by cold-worked fastener holes. Proto will perform numerous laboratory measurements on cold-worked coupons in the hoop and radial directions at the surface and subsurface, including the internal diameter of the holes, using its patented XRD tools. Proto will map these RS distributions and correlate that data with FEA and strain gauge data to establish the technical relationships for determining the effectiveness of the cold-working processes. In Phase II, Proto will deliver and demonstrate a rugged, portable XRD NDI system for measuring the effects of cold-working as well as the effectiveness of the cold-working processes. It will support an operational evaluation by trained NAVAIR personnel in a depot quality control environment.

Title:Fatigue Enhanced Cold-worked Hole FECH - Analyzer
Abstract:The Navy routinely uses a structural strengthening technique called cold hole expansion for increasing the fatigue life of primary aircraft structures that are fastened together. This process creates beneficial compressive stresses around the hole. However, variances in the process produce inconsistent results and no means exist to nondestructively quantify the process effectiveness. Resodyn Corporation proposes the development of technology based on a novel eddy current circuit and coil array that will map stress contours around the hole. Fundamentally, the circuit and coil arrangement is designed to be sensitive enough to measure changes in conductivity across the stress field resulting from various stress states around the hole and correlate the conductivity measurements to stress values. This approach has advantages over contemporary methods because it can be readily implemented into a small hand held probe that can provide either quantitative or go / no-go metrics in the field. The team assembled to research this technology includes a scientific consultant who has previously demonstrated feasibility of the proposed approach on a different application, the developer and major supplier of hole expansion tooling, a manufacturer of eddy current equipment, and product development engineers with demonstrated product to market success.

Title:An Accurate, Secure and Low-power Wireless Aircraft Tracking System
Abstract:We propose to design a tracking system for aircraft onboard carriers using a wireless mesh network with a point-to-point ranging capability. The system is formed by many Integrated Communication and Tracking Devices (ICTD) mounted inside the cockpits of aircrafts and in some selected locations of the carriers themselves, such as the island or the ceiling of the hangar bay. The unique strengths of this tracking system are: 1) Highly accurate and precise; 2) Low RF emission; 3) Energy efficient; 4) All-weather and; 5) No multi-path interference. Each ICTD contains four modules ---- a processor, a communication transceiver (CTR), a ranging sensor (RS), and a motion sensor (MS). CTR transmits very low power RF signals to meet the emission control limit and form a wireless multi-hop mesh network. The ranging sensor is capable of measuring the distance between another ranging sensor and itself. This tracking system is able to provide uniform coverage in the flight deck and the hangar bay areas in all weather conditions yet meet the emission control restriction. The accuracy is estimated to be +/- 1 foot for location and +/- 5 degrees or better in heading.

Title:Autonomous Aircraft Tracking Aboard Carriers
Abstract:Multispectral Solutions, Inc. (MSSI) proposes to develop a real-time asset tracking system to be used on an aircraft carrier. The real-time asset tracking system will leverage a commercial product called the Sapphire Digital Active Real-Time Tracking (DART) system developed by MSSI using Ultra Wideband (UWB) radio technology. Key advantages include real-time tracking with localization accuracy less than a foot, small form factor, extended battery life, and operation in severe multipath environments without interference from or to other operating systems onboard the carrier. In Phase I, MSSI will identify the modifications necessary to upgrade the Sapphire DART system for integration into the US Navy's aircraft carrier fleet. MSSI will study and identify how the system can be used to track the location and orientation of aircraft on the aircraft carrier flight deck. This study will examine the number of receivers, necessity of wireless receiver operation, placement of tags on aircraft, etc. Finally, MSSI will examine the current Sapphire design to meet navy environmental requirements. Additionally, MSSI will demonstrate the Sapphire system in operation on an aircraft carrier to track tags, vehicles and aircraft. In the Phase I Option period, MSSI will develop the modifications towards the Phase II system design.

Title:A Fault-Tolerant Real-Time CORBA Naming Service
Abstract:There is a natural tension between real-time predictability and fault-tolerance capabilities in computing systems. There is a need for both real-time predictability and fault-tolerance in defense systems; they must timely deliver the required functionality in the face of unexpected environments that deliver unpredictable events. As a result, the efficiency of defense systems is often compromised to allow the recovery from faults to be factored directly into the worst case execution time of operations in order to ensure real-time predictability. The Common Object Request Broker Architecture (CORBA) is a widely adopted, effective infrastructure for defense systems. A specification for a real-time variant of CORBA is supported by a number of commercial and open source products. A specification for a fault-tolerant variant of CORBA has been developed that supports strong consistency between replicas of objects. Unfortunately, neither of these specifications address the concerns of the other, so that a CORBA specification that supports both fault-tolerance and real-time is not available. The CORBA Naming Service provides a tractable and well-understood application of CORBA suitable as a candidate for evaluating the practicality of the techniques identified in research that has been directed toward reconciling the tension between real-time and fault-tolerance.

Title:A Fault-Tolerant Real-Time CORBA Naming Service
Abstract:Many mission critical applications are required to meet high degrees of simultaneous dependability and predictability requirements. The OMG's Fault-tolerant (FT) CORBA and Real-time (RT) CORBA help developers to manage applications' dependability and predictability requirements in isolation. It is still not possible to use CORBA to manage applications' FT and RT properties in unison due to contradicting strategies in the support mechanisms. This project will investigate how to reconcile the incompatibilities between the two specifications and to provide a design that simultaneously supports CORBA applications with both FT and RT properties. By developing a fault-tolerant, real-time CORBA Naming Service, we will explore mechanisms for implementing predictable FT mechanisms and evaluate strategies for specifying applications' FT and RT requirements. The Phase~I project will focus on addressing design issues in FT supporting mechanisms to eliminate non-deterministic behaviors, as well as benchmarking their performance with integrated FT/RT supports.

Title:Multifunctional, Low-Cost, Inorganic Seal Coatings for Radomes
Abstract:Barrier coatings to prevent moisture ingress into radome structures of advanced missile systems are a critical need for the Navy. Ingress of moisture during missile storage can degrade the critical sensor and guidance electronic components housed within the missile radome. The US Navy is developing missiles targeted for varying flight conditions which utilize many radome materials. A versatile coating solution is desired that address sealing of polymer and ceramic radomes adequately over the long-term. Inorganic coatings are preferred for this application due to their superior barrier properties, chemical resistance, and thermal performance. However, deposition of suitable inorganic coatings with adequate coverage for barrier performance is a significant challenge. A thin barrier coating based on aluminum phosphate composition is being proposed under this Phase I effort. The coating is derived using a solution-derived process which is low-cost and easy-to-apply and provides excellent adhesion to both polymer and ceramic substrates. Phase I work will include study of deposition, curing, and performance testing for both classes of substrates. The work will be conducted in close collaboration with a defense prime contractor. Phase II effort will be devoted toward prototype demonstration and further optimization of coating properties and development of roadmap for technology transition.

Title:Reduced Moisture vapor transmission coatings for Radomes
Abstract:Modern technology has developed materials that are highly durable and can resist a harsh environment, but one of the most damaging chemicals for electrical components is moisture. Even very low levels of water vapor can be fatal to sensitive equipment, particularly for guidance systems in missiles. The structural components of radomes are either porous fused silica or a variety of polymer matrix composites with glass fibers. The materials provide a level of protection from the environment, but are not adequate by themselves in preventing moisture vapor transmission. Several commercial coatings exist today to mitigate moisture, but these too are insufficient in providing the level of protection and length of service required. A need exists for a coating that will provide moisture barrier performance of 0.02g/m2/day or lower, thermal cycling resistance and resistance to abrasion and scratches during incidental handling of missiles for a period of 10 years. The new hybrid coatings will be both highly resistant to water vapor transmission and abrasion and scratch resistant.

Title:Compact Towed Sonar Array
Abstract:A major challenge facing the U.S. Navy's Anti-Submarine Warfare (ASW) mission area is the ability to effectively detect, classify, localize and neutralize quiet modern submarines in shallow water. To address this challenge requires deployment of distributed network centric sensor systems that provide the search rate needed to leverage the full complement of US Navy war fighting capability. Unmanned Surface Vessels (USV) and Unmanned Underwater Vehicles (UUV) outfitted with compact towed array sensors have the potential to deliver the transformational capability needed to meet operational objectives in the littorals. Current towed array sensors, including TB-23, TB-29A, TB-16 and MFTA, provide desired acoustic performance but are not optimal for deployment from an unmanned vehicle. Compatibility with these platforms requires significant reductions in sensor power, diameter, bend radius and production cost. Maintaining performance comparable to existing Navy tactical towed arrays requires reduced susceptibility to mechanical/vibrational noise and incorporation of directional sensors for left-right contact resolution. Development of next generation reliable compact towed arrays that can be stowed and deployed from unmanned vehicles, surface ships and submarines supports the Sea Shield Pillar of Sea Power 21 while achieving substantial fleet life cycle cost savings.

Abstract:Towed arrays for unmanned U. S. Navy platforms require engineering breakthroughs in a number of critical components due to the demands of reduced stowage volume, 0.5_ OD array diameter, low cost and improved directional and self-noise performance imposed by UUV/USV_s in the performance of their missions. Progeny proposes a system solution based on leveraging new, sufficiently mature sensing, array electro-mechanical, COTS electronics and processing technologies that support a near-term, integrated, open system solution. Key elements of the our approach include: a novel miniaturized vector sensor using single piezocrystal material, an autonomous beamforming and detection processing module being developed for distributed sensor networks, a truly protocol-independent, miniaturized towed array telemetry, and a deployment mechanism capable of handling 0.5_ OD arrays already under development by Progeny for surveillance programs. Our proposed array-related technologies and design approach are compatible with ongoing Navy low-cost towed array manufacturing initiatives. An option is proposed to demonstrate two key component technologies within 3 months of option exercise.

Title:Automated Mine Neutralization Vehicle
Abstract:Recent advances have been made in searching for and locating volume and proud mines in shallow and very shallow water. The procedure for neutralizing mines is still labor intensive, slow, expensive and dangerous. In this SBIR, OASIS and Lockheed Martin-Sippican (LMS) address the need for a ship, air or submarine launched unmanned vehicle to provide automated mine neutralization. The proposed Expendable Mine Automated Neutralizer (EMAN) vehicle will be a variant of the LMS production EMATT (Expendable Mobile Acoustic Training Target). Following the detection and localization by the reconnaissance UUV, an acoustic marker beacon will be placed in the vicinity of the mine and will have precise relative positions between the marker and the target. The EMAN's task is to transit to the beacon location, then transit to the position of the mine and await detonation instructions. The technical challenge to be addressed is the detection of the beacon signal in a noisy, bottom limited, very shallow water and dynamically complex environment, and then to transit to the beacon and the mine. With minor variants to the EMATT in hardware (adding hydrophones) and software, the EMAN system can be in production within the specified cost goals in the NEAR TERM.

Title:Automated Mine Neutralization Vehicle
Abstract:Present mine neutralization vehicles like the AN/SLQ-48 and the AN/ASQ-232 are delivered by much larger manned vehicles into close proximity to the mine. This permits the mine neutralization mechanism itself to be much smaller and less expensive. An unmanned delivery vehicle, the Mine Neutralization Delivery UUV (MNDUUV), for several small automated mine neutralization vehicles is proposed. Such a delivery UUV would permit the neutralization vehicle itself to meet the size (5" to 6" diameter) and cost ($10k to $25k) objectives by moving expensive navigation and transit propulsion capabilities into the delivery vehicle. The MNDUUV is proposed as a reusable UUV that is launched and recovered from a ship. One of the key attributes of the MNDUUV will be its ability to dock with a ship-deployed recovery mechanism. The initial phase of this proposal will focus on the design of UUV and docking drogue functions required to support the critical docking operation.

Title:Artificial Intelligence Techniques for Surface Threat Identification
Abstract:Stottler Henke proposes a software system, the Intelligent Surface Threat Identification System (ISTIS), based on Artificial Intelligence (AI) techniques and our previous work, an existing Navy ID system, the Intelligent Identification Software Module (IISM). ISTIS will automatically analyze the data associated with a track, hypothesize, draw inferences, and make ID related recommendations. These data include the tracks' location and/or velocity reported over time and other ID related reports such as IFF codes, visual ID reports, acoustic signature, specific emitter ID (SEI), ELINT signature, FLIR reports, intelligence reports, communications, etc. The ultimate goal of this proposed effort is to improve the quality and efficiency of the ID process. This improved performance includes better use of scarce ID resources, better ID estimations from available information, sooner ID determinations, prevention of ID "surprises", and operating successfully in more complex environments. The goals of the Phase I research are to understand the current and potential ID environment, especially in littoral areas of interest to the US Navy; elaborate the heuristics, algorithms and techniques for automatic ID analysis; prove the feasibility of the techniques through prototype development; and develop the Phase II system design.

Title:Autonomous Surface Threat Identification
Abstract:The Naval Autonomous Surface Threat Identification system will leverage Augmented Reality technology, advanced sensors and automated threat detection to enable superior surface threat detection aboard the Littoral Combatant Ship. Camera systems will be enhanced with magnification and non-visual optical sensors operating in the low light and infrared spectrums. Visual images of targets will be automatically or on-demand examined by intelligent agents to obtain and analyze threat related clues from the images. Image mapping and correlation to threat data bases will be created, and imported radar tracks will be monitored for clues to hostile intent (course and speed changes, etc.). Monitored track information will be collected and analyzed by a decision support algorithm and operator alerts will be triggered when a possible threat behavior is detected.

Title:A Real-Time Robust Autonomous Surface Threat Identification and Visual Knowledge Discovery System
Abstract:A set of robust software tools for automated identification/classification/recognition and tracking of surface threat among a group of non-threat entities is vital in the development of a good surveillance system. The increase in volumes of imagery data imposes a paradigm shift in the current surveillance systems used primarily only after the fact as forensic tools, to automatic knowledge exploitation tools to discover the relevant knowledge, forecasting the onset of (possibly catastrophic) events prior to their occurrences - such knowledge being critical for preventive actions across a number of government agencies - to detect, track and monitor (suspicious) objects and humans, their patterns of behavior and their associations in order to prevent possible calamities. Currently this capability is not available due to inadequate feature extraction and intelligent analysis tools that can in time communicate critical information collected and analyzed by various sensors. The objective of this project is the feasibility of an innovative Visual-Knowledge-Discovery system (VKD) to robustly and rapidly analyze actionable knowledge from visual data to identify and classify potential threats among a group of non-threat entities. The design and development of the system is based on a hierarchical/multi-resolution scene decomposition scheme to localize, recognize and track movement of objects of interest.

Title:Alternative Methods of Wireless Sensor Power via Novel Piezoelectric Fiber Composites
Abstract:Currently, wireless sensors have been used in variety of applications such as real-time data sharing, surveillance, in-vivo medical devices, condition-based monitoring, etc. that can revolutionize industrial efficiency, health monitoring, and data processing. Maximizing the use of wireless sensors onboard Navy ships will reduce the cost of maintenance and manpower. A state-of-the-art destroyer such as the DD(X), with its cutting edge sensors requires the use of heavy and limited lifespan batteries. To power such sensors, an alternative energy source to produce 10-100 mW continuous power is required. This proposal addresses that need via a novel approach to generate power from ACI's piezoelectric composites. Batteries are heavy with a limited life span, limited temperature range, and often replacing batteries in hard-to-reach locations, makes the use and inspection of wireless sensors much more difficult and perhaps impractical. Installation of power cabling can be expensive and time consuming and the wires add weight to the system. Piezoelectric materials, if devised properly, can convert up to 70 % of the otherwise wasted mechanical energy into electrical energy. Moreover, such a technology provides a low operating cost with little or no maintenance, high reliability, lower weight, and an efficient and permanent source of energy.

Title:Alternative Methods of Wireless Sensor Power
Abstract:The mission of H2Volt is to produce a long lasting fuel cell based mobile power source with a degree of magnitude capacity improvement over today's batteries. H2Volt power system uses patent pending fuel cell system integrated with a replaceable solid chemical fuel cartridge. Dr. Zhou, inventor of the technology, has over 7 year of battery and fuel cell research and development experience. H2Volt proposes to explore and demonstrate the feasibility of a "fuel cell battery" that generates 10-500mW constant power with 10 times energy capacity of alkaline battery, a life of 5+ years, easy integration with wireless sensors, and zero maintenance for the life of the sensor. It will develop a novel method of self-regulating, passive, "air breather" fuel cell that requires no moving parts, but maintains sufficient hydration of the membrane to provide stable and reliable power. The project will perform limited prototyping, testing, structural and finite element analysis simulations to validate the design. Initial commercialization efforts will be through OEMs as a primary power of mobile electronic devices. In military applications, the strengths of solid fuel, increases in energy densities and shelf life, lightweight, safety and environmental benefits will make H2Volt system an ideal solution.

Title:Alternative Methods of Wireless Sensor Power
Abstract:Hi-Technology, Inc. (Hi-Z) proposes to use thermoelectric devices in developing an alternate method of providing power for wireless sensors. A thermoelctric gneator (TEG) converts heat directly to electicity in a compact, reliable, robust, solid-state module. Hi-Z has developed thermoelectric module technology that is well suited for this Navy application. Using the experience gained in the current Phase II SBIR where a small power-harvesting TEG is being designed and fabricated for Navy wireless sensors, Hi-Z is planning to examine all potential heat sources and select the best one for the conceptual design of a TEG for this application generating 10-100mW constant power and having a minimum life of 4 years. In the Phase II SBIR, Hi-Z is designing a TEG that utilizes the heat transfer between shipboard waste heat sources and the ambient air to generate electricity for wireless sensor. In two prior Navy applications Hi-Z designed TEGs for senors wih the one installed on USS Monterrey (CG61) operating on just a 5C difference between the temperature of the space inside the ship and the ships hull. In order to satisfy the desired small form factor for the alternate power source, Hi-Z proposes to apply its innovative Quantum Well thermoelectric technology that has four times higher conversion efficiency than SOTA bulk thermoelectrics.

Title:Integrated Shipboard Multi-function Surveillance System
Abstract:Around-the-clock vigilance of valuable military assets, even in an ostensibly secure setting, requires substantial human effort and even the slightest error can result in disastrous consequences. MaXentric is proposing ISWAS, an Integrated Shipboard Wireless Autonomous Surveillance system, to reduce the probability of error and allow trained personnel to perform other critical tasks. ISWAS is a comprehensive solution, covering, sensor interface, wireless transport network, and data interface. ISWAS utilizes open standard architectures such as OSGi and allows multiple operators to utilize the same sensor network for different tasks. ISWAS combines Commercial Off The Shelf (COTS) wireless networking components with a hardware adapter that uses innovative yet proven technology in order to create a jam-free, secure, and robust wireless sensor network. The control modules for COTS sensors are rapidly deployable plug-and-play modules that support multiple sensor types, and the Fuzzy Logic user interface allows the operator to set criteria for intelligent autonomous surveillance.

Title:Integrated Shipboard Multi-function Surveillance System
Abstract:Williams-Pyro, Inc. proposes to develop a plug-and-play, distributed surveillance system called Wireless Energy-efficient Surveillance System - Open Architecture (WESS-OA) that integrates and automates full perimeter ship security to reduce workload. WESS-OA uses Wireless Intelligent Nodes (WIN) that collect and process data from sensors, such as standard video, low-light video, infra-red and optical-based sensors. In addition to visual information processing, the WESS-OA allows other sensory input data such as those from audio, vibration, chemical detection, ultrasound, and other RF-based sensors. WESS-OA is based on proven concepts such as (1) collaborative sensing and distributed processing involving sensors and WINs, (2) pervasive computing and central processing involving workstations and handheld units, (3) software radio technologies for dynamically reconfigurable wireless links. Each WIN uses standard low-power processors/hardware, communication protocols, interfaces, and energy-efficient data processing algorithms. The WINs continuously collect sensor data, collaborating to assemble a complete interpretation of the environment. Sensors monitoring the same area are connected to the same WIN, which tracks objects in that area. The WIN also pre-processes data if intelligent sensors are not available. In particular, WINs run the algorithms to pre-process the data (through change detection) from each video source.

Title:Autonomous Sensor Health Monitoring for Modern Shipboard Control Systems
Abstract:Next generation U.S. Navy shipboard control systems are being designed to provide much higher levels of machinery automation than their predecessors. The U.S. Navy is investing in these sophisticated systems with expectations of improved system performance and reliability. Moreover, reductions in the number of shipboard personnel required to operate the engineering plant may result in lower total ownership costs for these modern ships. Sensors distributed throughout the ship, numbering in the thousands, provide the required inputs to the automated ship control system. The cost in labor and materials to maintain and calibrate these sensors presents a risk to the anticipated cost savings. Furthermore, untimely sensor failures could cause the crew to lose confidence in the machinery control system. Barron Associates, Inc. (BAI) and its partner, Sperry Marine, a Unit of Northrop Grumman Systems Corporation, propose to develop an autonomous sensor health monitoring system that will leverage BAI's proven diagnostic techniques and Sperry's shipboard control system application expertise and development facilities. The development of a comprehensive fault and failure anomaly detection and isolation system will bring together flight-tested algorithms developed by BAI for online, real-time parameter identification and generic algorithms developed by BAI for sensor monitoring in any complex dynamical system.

Title:Autonomous Monitoring and Assessment of Sensor Data in Support of Calibration and CBM
Abstract:Impact Technologies, in cooperation with Northrop Grumman Ship Systems, propose to develop and demonstrate a comprehensive sensor health assessment software product that is capable of detecting sensor faults and isolating corrupt data acquired from critical ship systems. The proposed concept is innovative in the fact that it is based on a data-driven modeling methodology, which has generic application to both high and low bandwidth signals, and is capable of detecting subtle changes in signals resulting from calibration or sensor drift issues. In addition, based on the fact that the approach is highly scalable (not limited to the number of sensors), it can be applied across any ship system and readily support the condition-based maintenance (CBM) and mission readiness philosophies expressed in the DD(X) program. The signal health software modules, will not only be capable of real-time sensor fault detection (wired or wireless), but it can also recover from the sensor faults using the signal's predicted value until the sensor is repaired or replaced. This will allow the ship systems being monitored to continue to operate as normal without the need for abrupt maintenance actions that are costly to mission readiness and effective operations. Finally, the signal monitoring modules will operate in both transient and steady-state modes and will be implemented within an open-systems, modular software architecture suitable for any 3rd party system integration. Well-documented, dynamic link library (DLL) modules will be tested on selected NG systems relevant to DD(X) and delivered during Phase I for assessment into existing modular architectures such as the Navy's ICAS.

Title:Advanced Structural Watertight Door System
Abstract:Navy doors have been essentially built the same way for sixty years. The design has been proven in battle and sea use, but it also has been the source of significant maintenance and some safety concerns. Excessive weight and corrosion are the source of the continual maintenance. Door systems that solve the maintenance problems can be formed by a proprietary super plastic forming process. This process is capable of forming door systems that meet operational and pressure requirements while reducing door weight by almost 50% and eliminating corrosion. The process is also flexible enough to allow modifications to door stiffness and to accommodate door designs that are compatible with current ship bulkhead configurations. In Phase I, we will demonstrate that our approach is feasible through experimental validation and produce a preliminary concept design and associated component validation plan. In the Option Phase, we will develop and produce the designs for the super plastic forming tools.

Title:Advanced Structural Watertight Door System
Abstract:New naval ship designs will result in faster & lighter vessels manned by fewer sailors. These design changes necessitate weight savings, reduced maintenance time, and life cycle cost reductions in all shipboard components. The objective of this project is to develop a new and improved watertight door system for future and existing ships that meet these requirements. Juniper Industries has been a primary supplier of standard navy watertight doors for several decades. Here, we propose to team with Walz & Krenzer, Inc. to focus on improving the primary areas of concern on all existing standard navy watertight doors, namely the the weight, the dogging system, the sealing system, the hinging system, and the life-cycle costs. The result will be watertight doors that are lighter, more durable, require less maintenance,and that are fully watertight. In addition, it is anticipated that the new door system will have the capacity to be used with a variety of panel materials, increasing the potential for both navy and commercial watertight door applications. Phase 1 research will demonstrate the economic and technical feasibility of two new dogging, hinging, and sealing systems, as well as investigating the use of composite door panels.

Title:Advanced Structural Watertight Door System
Abstract:U.S. Navy quick acting interior watertight door systems currently in service are heavy, unreliable and very expensive to maintain over the life cycle of the ship. The current Navy standard door system design is over 50 years old and suffers from a number of design deficiencies including the use of heavy corrosion prone materials, excessive number of penetrations, excessive number of parts and metal-on-metal contact during dogging operations. The complex dogging system consisting of rotating metal dogs and numerous tie bars with rotating joints require constant maintenance to keep the frictional parts lubricated and to keep all the components adjusted properly. Corrosion and metal-on-metal friction causes these parts to rapidly wear out and fail, ultimately requiring replacement and repair, resulting in high life cycle costs. This project will develop an innovative, cost effective, lightweight, corrosion and fire resistant, durable, quick acting composite interior watertight door (CIWD) system that will meet the structural load and environmental exposure design requirements for Navy interior watertight door systems. The lightweight CIWD system will significantly reduce life cycle costs by reducing the number parts and door penetrations, eliminating metal-on-metal contact and corrosion of locking mechanism parts, and the need for lubrication of moving parts.

Based entirely on Commercial-Off-The-Shelf (COTS) hardware and software, DDL OMNI proposes to instrument a system to quantifying the performance of sensors to NIST traceable standards. The proposed device is a self-contained calibration test standard housing a commercial Pentium processor and interface cards capable of simultaneous multi-channel source output and measurement input. Combined with tailored application software the design is modular, scaleable, extensible, traceable and consistent with commercial development trends. Designed to meet open architecture tenets, protocols and communications, the device ensures interoperability with multi-vendor equipment and future sensor developments. The resulting device is capable of performing a wide array of simulation/stimulation output, measuring and quantifying the sensor/system response output, and providing simultaneous monitored control of the output source signal. The packaged system provides comprehensive automated closed-loop calibration and monitoring with operator intuitive displays and indicators for rapid status assessments. Further, once implemented, the device can analyze historical sensor performance trends for the development of condition-based calibration requirements.

Abstract:IAC proposes to design a portable platform that will implement NIST (National Institute of Standards and Technology) traceability standards for calibrating shipboard and industrial sensors. This platform will enable a single individual to perform automated closed loop calibration, thereby helping the Navy achieve its goal of reducing crew size requirements for the maintenance of large sensor networks. The use of remote desktop technology and remotely-controlled circuitry will allow a single maintainer to possess the controllability and observability required in order to perform sensor calibration procedures that presently require at least two maintainers. In addition, IAC will develop circuitry that meets the accuracy and stability levels required to maintain NIST traceable calibration standards. The protocols in the proposed concept platform will be based upon open standards and will strive towards compatibility with products from other vendors who may play critical technology roles in the overall solution that the Navy seeks. This circuitry and systems developed in this effort will support Navy documentation process for compliance to NIST traceability.

Title:Portable Calibration Standards for Traceability
Abstract:The problem: Navy technicians spend hundreds of hours each year calibrating thousands of ship sensors on a fixed schedule. Figuring 15 minutes of labor for manually calibrating a single sensor, a facility with 100 sensors could spend 300 man-hours or more every year for monthly calibrations, easily reaching a $15,000 annual budget. Within Navy ships, this annual estimated budget would nearly triple, as Navy vessels such as the DDG-51 have nearly 2,700 sensors that need calibrating. Our solution: To decrease the time that Navy technicians spend calibrating sensors by over 75%, Williams-Pyro, Inc. proposes to develop the Accurate Sensor Analysis and Calibrating Tool (AccuSACT). AccuSACT will be a portable device approximately the size of a briefcase that will perform two functions: (1) accurately identify drifts in sensor readings from the standard reading and (2) indicate when and how technicians should calibrate the sensors. Once AccuSACT identifies a faulty sensor, the device will show test methods, criteria, and protocols defined by the Standard Reference Material distributed by the National Institute of Standards and Technology. In addition, AccuSACT hosts the Navy's Interactive Electronic Technical Manuals to provide technicians with additional instructions concerning sensor troubleshooting, calibration, and configuration management.

Title:Textile for Under Armor Blast Protection
Abstract:A fabric layer that provides shock absorption and energy dissipation functions is proposed to provide improved blast protection. Made from piezoelectric materials, the fibers convert the kinetic energy of mechanical impact into an electrical signal that is dissipated by the fabric. Piezoelectric fabrics can potentially address all of the stated solicitation requirements: Provide protection against pressure waves and fragmentation caused by detonation of IED's and other explosives; small, lightweight, flexible, breathable and able to be integrated into soldier clothing and other wearable gear; does not interfere with soldier mobility, increase thermal signature or induce fatigue. The applicant has conducted previous SBIR work to evaluate piezoelectric materials' effectiveness in wearable applications to damp vibrations, as well as to develop and characterize piezoelectric fabrics for use as portable and/or wearable power sources. That work provides a solid foundation to address the current solicitation. While still in the development stage, the piezoelectric fabric prototypes (see Section D) were produced on a commercial pilot production line. There is therefore a clear path to scale-up any results to production should the current project prove successful.

Title:Exoskeleton Blast Protection for IED
Abstract:Warwick's expertise with high-performance, protective textiles has led to the development of innovative solutions, including new body armor systems for multiple threats and the protective crash bag material used to land NASA's Spirit and Opportunity Mars rovers. We propose to create a lightweight, flexible, multi-layered system that will effectively mitigate the powerful forces of tension and compression that can cause traumatic limb separation caused by IED blast. Most existing body armor systems use a hard plate to protect against ballistic threats to the torso, and some also contain a softer fabric system to provide protection from fragmentation, but there is nothing available to today's warfighters that addresses issues of limb separation. This lack of protection leaves the wearer's extremities vulnerable to severe, often fatal, injuries caused by blast overpressure. Our research efforts will seek to achieve an optimal material combination that can absorb and dissipate energy from overpressure and can also withstand fragmentation of 0.100-1.2g. Proper selection of materials is vital, as each component will provide a critical level of protection. Furthermore, materials chosen must also be pliable enough so that end products meet dexterity, agility, and flexibility needs, especially when worn in combination with traditional hard-round ballistic body armor.
