| 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. |

| 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. |

| 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. |

| 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. |

| 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. |

| 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. |

| 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. |

| 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)." |

| 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. |

| 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. |

A considerable amount of hardware fabrication and testing will be conducted at in-house facilities of KaZaK and Pall.

| 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. |
