| Title: | Chrome-Free Room Temperature Curing Fuel Tank Coating |
| Abstract: | The Phase I approach to a non-chrome, room temperature curing fuel tank coating is based on using an epoxy-polyisocyanate resin system in combination with patent pending, non-chrome corrosion inhibitors. The resin system has demonstrated the ability to meet the requirements of AMS-C-27725 when pigmented with strontium chromate. The non-chrome inhibitve pigments have demonstrated salt spray resistance equivalent to strontium chromate pigmented, epoxy polyamide coatings qualified to MIL-PRF-85582. Preliminary testing has demonstrated the feasibility of achieving corrosion resistance with the non-chrome pigmentation in the epoxy-polyisocyanate matrix. Experimental variables to be explored are inhibitive pigment type, extender pigment type, inhibitive pigment-extender pigment ratio and pigment volume concentration. |

| Title: | Chromate-Free, Room-Temperature Cure Fuel Tank Coating |
| Abstract: | The objective of the program is to demonstrate through the use of novel corrosion inhibitors and coating formulation a chromate-free, room temperature curing, environmentally acceptable fuel tank coating that meets the performance requirements of SAE AMS-C-27725. Luna Innovations, Inc. will formulate and evaluate novel coating formulations specifically engineered to inhibit corrosion and microbial growth, resist environmental degradation while maintaining compatibility with existing aircraft materials and structures. Accelerated development of the new coating system will be achieved through the use of proven resin systems modified with corrosion inhibitors and other additives to produce a tack-free coating with excellent physical and barrier properties that remains suitable for spray applications. Excellent corrosion protection will be achieved with low-cost, environmentally acceptable inhibitors, including plant-based extracts and novel high-performance chrome-free pigments. Luna will demonstrate the performance properties of the coating system through the appropriate test methods and in direct comparison to a chromate-bearing military qualified product. Substantial cost and performance benefits with concomitant decreased environmental impact will be realized from the novel high performance system formulated to conform to existing logistical and operational requirements. |

| Title: | Chromate Free Polyurethane Fuel Tank Coating |
| Abstract: | Current aircraft fuel tank coatings contain chromates that provide excellent corrosion protection. Unfortunately, these hexavalent chromates are known carcinogens and their use and disposal is strictly regulated. In fact, in much of the developed world, their use and disposal are being banned outright. An ideal aircraft fuel tank coating would provide effective corrosion protection without the use of chromates. In this Phase I proposal TDA will develop a chromate free, room temperature curing fuel tank primer using nanoparticle additives which contain releasable corrosion inhibitors. |

| Title: | High Reliability Mechanical Fiber Optic Splice |
| Abstract: | The proposed approach provides a high performance mechanical optical fiber splice of single piece construction. Leveraging on advanced glass and polymer material processing technologies, the new splice design offers advantageous attributes of compactness for use with minimum space intrusion, passive self-alignment of the fiber core in all directions, easy guided fiber insertion, quick action, and a built-in cable retention nozzle that also alleviates the cable strip and fiber tip cleave requirement. Moreover, the approach is based on fiber optic packaging processes that are proven as the most cost effective and highest reliability in the optical fiber component industry. The design intrinsically eliminates damaging thermal cycling stress, providing excellent temperature stability and longevity. The all-glass sealed splice enclosure and its polymer alternative are also particularly well suited to withstand severe environmental conditions. The feasibility of the glass mechanical optical fiber splice has been successfully demonstrated. In this Phase I program, state-of-the-art ruggedized fiber splices that meet the low loss and reliable operational requirement in military/aerospace avionics fiber-optic network environments (including the extreme ?75 to +200 degree C range) will be further developed and demonstrated. |

| Title: | All Silica, Low Energy Mechanical Fiber Splice for Fusion Replacement |
| Abstract: | Optical Fiber has revolutionized the communication industry in the last few decades. However, fiber to fiber connection technology still lags behind copper in both ease of reconnection and signal loss. Fusion of the fiber with active alignment is the most widely used technique for making fiber to fiber connection with the least amount of signal loss. However, all of the fusion methods utilize high energy methods to melt the glass to fuse the fibers together. A new technology is required for performing splices on aircraft such as the F-18 and new JSF in the presence of jet fuel and in the limited space available. Luna Innovations is proposing a low energy, chemical method of constructing an all silica splice for optical fibers. Luna will build prototype splices to demonstrate the key technology during Phase I and compare the performance to existing splice methods, mechanical and fusion, for volume required for splice construction, tensile strength, optical loss, and thermal cycle performance. A splicing system utilizing the chemical glass bond will be designed in Phase I and fully developed in Phase II. Prototype splices will be constructed and fully characterized and proven to meet the Navy's needs during Phase II. |

| Title: | Ruggedized Laser Diode Package for Wavelength Division Multiplexed (WDM) Networks |
| Abstract: | This SBIR project plans to develop a WDM transmitter qualified for the harsh environment of military and aerospace avionics applications. The fiber pigtailed transmitter will employ a Sampled Grating Distributed Bragg Reflector (SGDBR) InP laser to achieve a data rate of 310Gb/s. The laser will be used in conjunction with a wavelength locker to accomplish >80 wavelength channel tunability. A novel approach to the design of wavelength locker based on planar lightwave circuit (PLC) technology is proposed to achieve the low-profile requirement (package height < 0.140"). In addition, latest developments in design of thermoelectric coolers will be utilized to provide stable performance over extended temperature ranges of -40øC to 100øC. In Phase I, the focus will be on design and analysis of the new wavelength locker and high performance thermoelectric cooler. Motivation for this initiative comes from growing demand for high data rate and cost-effective, standardized packaging technology for harsh environments. Traditionally, specialized laser modules have been employed in military networks. Increasing data rates demand use of WDM transmitters. However, custom made products will result in significant cost. Accordingly, there is an interest in developing transmitters manufactured by established processes in telecommunications industry. |

| Abstract: | Diode laser module for wavelength-division-multiplexed networks in rugged military avionic environment must be capable of large operating temperature range from -40C to 85 C and must have an ultra-low profile of <0.14". Typical commercial packaging for optoelectronic devices is not adequate. Here we describe a new packaging platform technology involving our recently-developed integrated miniature precision lens on silicon bench capable of addressing the present limitations. The miniature lens is referred to as "Superlens". In the proposed work, ruggedized laser diode module for military avionic applications will be realized based on our Superlens integrated packaging (SLIP) platform. The powerful SLIP platform has the advantages of: (1) Large Temperature Range; (2) Ultra Low Profile; (3) High Modulation Frequency; (4) In-Module Optical Isolator and Wavelength Locker; (5) High Fiber Coupling Efficiency; (6) High Manufacturability and Component Expandability; (7) Low Optical Packaging Costs via Passive-Alignment; (8) Low Electronics Packaging Costs; (9) Highly Integrated with monolithically integrated Superlens, sensors, heaters, RF lines, and electronic circuits, leading to ruggedized compact laser diode modules with high optical, electrical, thermal, and mechanical performances, as well as high manufacturability and lower costs. |

| Title: | Ruggedized Laser Diode Package for Wavelength Division Multiplexed (WDM) Networks |
| Abstract: | Advanced Navy platforms will need to transfer enormous amounts of data between sensors, data processors, storage systems and users. WDM networks offer the best possible solution to the bandwidth requirement. Tunable laser based WDM networks have many advantages over the fixed wavelength laser based networks which are rapid adaptability of the network resulting in improved efficiency and survivability, in addition to being lower cost. The most critical subsystem in the new generation of WDM networks is the tunable transmitter. Princeton Optronics (PRO) offers to develop rugged low profile tunable transmitters based on Princeton's high performance tunable laser. PRO has the best tunable laser in the industry and this technology will be further developed to build a rugged low profile transmitter for both digital and analog transmission. In Phase I of this program PRO proposes to establish the requirements and develop new technology required for this rugged WDM transmitter and integrate them into a working bench top model. This model will be evaluated through bench top measurement as well as mechanical and thermal simulations to demonstrate the feasibility of building a robust and manufacturable low profile widely tunable WDM transmitter in phase II. |

| Title: | Advanced Radiating Apertures for Reduced Signature Platforms |
| Abstract: | There is a critical need to increase the capability of new apertures and arrays to support electronic attack on advanced airborne reduced signature platforms such as Joint Strike Fighter (JSF). New apertures must have the following characteristics: scalable with high-power capability, ability to handle high power with low observable integration, electronically steerable, provide beam agility, and support bandwidth requirements. FIRST RF is proposing an antenna design that takes advantage of an optimal lattice design. The proposed lattice design provides for an improvement in scanned array bandwidth. The lattice geometry is compatible with signature reduced array techniques. In addition, improved element designs incorporating techniques in miniaturization, broadband matching, and reduced and shared cavities will provide for further bandwidth extension within the scanned array environment. Efficiently extending the bandwidths of the C&D bands of an EA antenna suite may provide for the ability to reduce the total number of EA apertures to three versus the current four. This will provide for less impact on the aircraft signature in installation. A key element design under consideration is a slot-line spiral which has inherent LO characteristics. |

| Abstract: | WaveBand Corporation (WaveBand) proposes to design and build a compact light-weight 2-D wide-band electronically beamsteering radiating aperture for multi-mission high-power electronic attack. The aperture operating at frequencies below 10 GHz is based on a new approach to electronic beam forming developed at WaveBand. The new approach radically differs from existing phased array technology. It promises dramatic cost and weight reduction and environmental stability, while providing digital beam forming that includes steering, tracking, and nulling; individually controlled simultaneous multiple beams; and extremely flexible reconfigurability. The proposed aperture is based on externally controlled active wide-band antenna pixels and consists of several separate linear sub-arrays. In this Phase I project, the feasibility of the approach will be established through a complete design of the whole antenna and through the demonstration of a breadboard prototype. |

| Title: | Multi-Decade Photonic Band-Gap Antenna |
| Abstract: | Foster-Miller will demonstrate using new electromagnetic materials to implement an innovative miniaturized multi-decade bandwidth antenna for omni-directional broadband communication and electronic countermeasure applications. Liquid crystal polymer (LCP) will be used to make a hermetic radome and support metallization for the ground plane and radiating structure. Single crystal Al2O3 will provide a low loss, high dielectric constant substrate for the wideband antenna. In addition, photonic band gap (PBG) structure will be embedded in the structure of the Al2O3 to mitigate loss within the high electric permeability dielectric. All of the materials and manufacturing steps in this antenna are cost-effective and highly scalable. The single crystal Al2O3 will be made with an innovative process which yields net shape parts which may have arbitrary curvature. The proposed antenna element will provide a large bandwidth with a target operating range that spans 100 MHz to 20 GHz. The metallized LCP radome has a 200øC operational temperature so the antenna can function at higher power than conventional antennas. The combination of frequency agility and power handling capability of the proposed antenna element can be used to make arrays with previously unattainable performance in ground to satellite communications and jamming on the run capabilities.

| Abstract: | A novel anisotropic artificial dielectric material is proposed for integration into airborne antennas to achieve size and weight reduction, along with reduced radar cross section (RCS). Development of the lightweight and low loss material will be based on frequency selective surface technology, where a homogeneous block of dielectric material can be replaced with an electrically equivalent lamination of circuit boards and foam. The material will be incorporated into a spiral antenna to increase the permittivity in the plane of the spiral while maintaining a low permittivity normal to the spiral. The concept will be demonstrated by designing, fabricating, and testing a spiral antenna that operates over a multi-decade bandwidth in the 100-20,000 MHz frequency range and is suitably small and lightweight for integration onto a low-RCS tactical aircraft. |

| Title: | Improved Airborne ASW Localization to Attack Using Continuous Active Sonar |
| Abstract: | The Navy's current airborne ASW active sonar systems rely on pulse type sonars to develop accurate localization to attack solutions. To improve this capability, pulse sonars require: 1) higher source level sonobuoys resulting in larger and heavier sources, 2) higher energy sources that may require battery chemistries that have safety issues and/or high costs, and 3) extensive and costly marine mammal mitigation procedures. The OASIS/BBN team proposes to design and analytically demonstrate a continuous active sonar (CAS) approach that will improve target localization performance using smaller and lighter sources that require significantly less source level thus minimizing the adverse impact of active sonar on marine mammals. We will leverage our state-of-the-art understanding of CAS operation (patent application pending) that overcomes the ambiguity in target range and speed inherent in other CAS systems. Our systematic approach to system design will produce an effective and robust sonobuoy-based target localization to attack solution ready for assembly and demonstration in Phase II. |

| Title: | Continuous Active Sonar Signal Processing |
| Abstract: | Current acoustic localization systems utilize a traditional pulse type sonar approach. A low power alternative, which would be more environmentally friendly toward marine mammals while maintaining required performance, is desired. Continuous wave systems that operate at lower average power could provide a solution to these requirements. Continuous tracking will also be possible, resulting in potentially more accurate localization of the target. Doppler effects can be exploited more completely with continuous active sonar operation. Although continuous wave systems have been used for radar applications, their possible applicability to acoustic localization systems has never been determined. Self-jamming, and blind speeds difficulties must be addressed. High clutter rate continuous tracking must be developed. Signal Systems Corporation's approach is to emphasize the signal processing aspects of continuous active sonar (CAS). This allows us to address, in Phase I, the high-risk elements of self-jamming, blind speed and tracking issues. We will develop waveforms, direct blast cancellation, space-time adaptive, and track-before-detect algorithms for CAS operation. We will extend our existing multistatic simulations to assess the applicability of CAS operation to acoustic localization. We will demonstrate direct blast mitigation techniques in Phase I using air-coupled and underwater data. |

| Abstract: | Both passive and active Sound Navigation and Ranging (SONAR) have reached performance plateaus by fully exploiting time-frequency space coherent processing. Potential exceptions are bi-static and multi-static SONAR using continuously transmitted pulse compression signals. This proposal presents the Continuous Active M-sequence SONAR (CAMS) approach to resolving this issue. The CAMS approach holds promise for extending temporal coherent processing times to achieve gains of as much as 36 dB over conventional 'Ping then Listen' mono-static SONAR. The CAMS signal processing approach is detailed and a work plan that establishes a Figure of Merit (FOM) verses 'Ping then Listen' SONAR, a preliminary tactical Concept of Operations, and optimization of CAMS functional parameters is outlined for the Phase I Base Program. Additionally, a work plan is provided for the Phase I Option Program that includes the development of the CAMS system requirements specification and a preliminary functional design. This Phase I approach is shown to be the building blocks for a follow-on Phase II program that will implement prototype CAMS in the operational environment with the goal of future migration into an anti-submarine warfare (ASW) Fleet asset as well as a commercial commodity. |

| Abstract: | Impact Technologies, with the support of Lockheed Martin, proposes to develop and demonstrate a model-based software for the design and development of a Self-Evolving Maintenance Reasoner for PHM systems. Impact Technologies will develop and demonstrate a web-enabled software tool set, including advanced maintenance reasoning technologies within an open-systems software architecture, to support a comprehensive Self Evolving Maintenance and Operations Reasoner or SEMOR. The development and integration effort will consist of many elements, ranging from model-based reasoning to OSA-CBM interface development, with various sources of data, information and knowledge being considered to obtain a truly intelligent and evolvable maintenance decision support system. One of the key components of the proposed system, consists of the generic reasoning algorithms and Maintenance Integrated Models (MIM) containing PHM, FMECA, sensor, and maintenance information. In addition, the open systems architecture (OSA) and associated software interfaces to existing JSF asset management systems (i.e ALIS) and PHM software containing pertinent maintenance and logistics management information will be addressed. Most importantly, the SEMOR system will employ a combination of case-based and Bayesian processes to evolve the underlying Maintenance Integrated Model (MIM) when given maintainer feedback. The SEMOR system will be demonstrated on one of many JSF PHM applications Impact is involved in including the drivetrain clutch, actuation hardware, and power and thermal management systems. |

| Abstract: | The Joint Strike Fighter Program (JSF) will produce the most sophisticated warfighter in the history of military aviation. JSF is unique as a major weapons system acquisition program in that the economics of system operation, support and maintenance are being developed concurrently with the technology. The JSF Autonomic Logistics (AL) Program aims to minimize operational and support costs by increasing system reliability, reducing maintenance requirements to essential levels. Using Prognostics and Health Management (PHM), materials and maintenance are ordered/performed only when needed, obviating costly routine scheduled maintenance, and reducing aircraft downtime. This vision of efficiency and responsiveness implies real-time communication between the intelligent air vehicle, industrial contractors and their suppliers, and the aircraft maintenance and support team. All of these entities require access to prognostics based on sensor data or life cycle models, and historical information on maintenance to optimized decision making in support of PHM. Here, IAC addresses the need for an intelligent software infrastructure system to manage this complex system. This system features an adaptive knowledge base of maintenance information and distributed intelligent agents which analyze sensor data, PHM model outputs and past behavior to recommend actions under dynamic and uncertain conditions. |

At least one technique will be implemented for a Phase I concept demonstration using a sample/example data set. The Phase I effort will also explore the application of the developed techniques for the update of knowledge models used by QSI's own suite of health inference and diagnostic tools. The requirements developed in Phase I will be used in Phase II for the full-scale development of a software component that can be integrated with an asset readiness management system in Phase III. |

| Title: | Next Generation Data Fusion Architecture |
| Abstract: | The task of defining a data fusion system architecture for real-world use dictates a system engineering approach. It is not enough to simply identify the "most optimal" algorithms for combining the data of interest. Real-world concerns demand a litany of compromises be made, most of which result in the system diverging from its optimal operating point. Equally important is the need to consider the difficulties that will be encountered in the implementation, integration testing, and maintenance phases of the system life-cycle. Too often these tasks are insufficiently addressed in the design phase. This inevitably results in interoperability and software/hardware upgrade issues that render the system performance and/or cost/benefit ratio less optimal than it could have been if these concerns had been accommodated in the system architecture design. A generic system architecture design can ensure a suitably flexible product that addresses the problems encountered in real-world airborne command post systems. Functional allocation and infrastructure design ultimately define the capability of an architecture to adapt to unexpected environments and changing requirements. In addition, such an architecture could be utilized as the starting point for application to virtually any data fusion system. |

| Title: | Next Generation Data Fusion Architecture |
| Abstract: | Combining data from multiple sources into a single coherent "picture" is a fundamental challenge to battlespace management. Today's combat systems are a result of the Department of Defense's historical federated acquisition process. These individual development programs produced individual stovepiped systems, now part of the legacy baseline. Comprising various interfaces, information structure, and data elements, these incompatible systems are difficult to integrate within a Service, and nearly impossible to integrate across Services. This has hindered interoperability within battlespace operations because of the inability to take advantage of intelligence and open sources of information. Next generation architecture should provide real-time fusion performance monitoring capability and algorithm assessment that permits development of an exploration platform to capture algorithm performance information and development of an optimal solution based on actual performance with the system's data.The overall goal of this effort is to produce an efficient and portable data fusion solution for the E-2C. This solution will break down the technical barriers associated with interoperability and will allow legacy and new systems to seamlessly interoperate, while minimizing processing and bandwidth resources to fit within existing system capabilities. |

| Title: | Next Generation Data Fusion Architecture |
| Abstract: | The potential disinteroperabilities and inefficiencies of current fusion architectures can be mitigated in a number of ways including reduced, coordinated, and standardized coupling of components. This proposal is for an ontology-based fusion architecture that will enable fusion agents to operate in independent, yet coordinated, manners. It is based on recent research in the area of ontology-based fusion in the international fusion community. Yet we will show how the approach is also well-grounded in actual DoD fusion systems and algorithms experience, indeed the idea of an ontology-based fusion resulted from many years of fusion project experience. What is planned for the Phase 1 effort is two parallel tracks, (1) develop the theory of ontology networks as a basis for inference; and (2) proof-of-concept demonstrations of the efficacy of the approach. For the proof-of-concept demonstrations, we plan scaled down experiment to verify the feasibility of independent fusion modules (inferlets) to operate within an spreading activation network based on an ontology. We will use a subset of the C2 Core ontology to support experimentation with already-developed algorithms for, (1) tracking filters, (2) association and assignment, and, if the Phase 1 option is exercised, (3) ESM/ELINT classification and identification. |

| Title: | Sensitive Bearing Diagnostics for Rotorcraft Transmissions |
| Abstract: | Achieving true condition-based maintenance of advanced rotorcraft transmissions will require sensitive monitoring of bearing dynamics to characterize the gradual degradation of their condition. This is particularly difficult for the planetary gear bearings of epicyclic gearing, which can only be "heard" through a gear mesh with potent dynamics of its own. Foster-Miller has a proprietary diagnostic analysis technique, called Dynamical Instruments, which is extremely sensitive to gradual changes in system condition. In the Phase I effort, we will analyze existing seeded-fault data to demonstrate the feasibility of applying the Dynamical Instruments technique to achieve sensitive monitoring of bearing condition in epicyclic gearing. We will also coordinate our plans with advanced rotorcraft transmission development efforts to plan the advanced development work of Phase II. The Phase II effort will involve extensive data collection and analysis to produce a demonstration prognostic system for advanced rotorcraft transmissions. (P-040099) |

| Title: | Fault Detection in Ceramic Hybrid Bearings using ImpactEnergyT |
| Abstract: | Impact Technologies, in cooperation with the Timken Company, proposes the development, implementation and validation of diagnostic and prognostic (D&P) technologies specifically designed for real-time, automated health assessment of ceramic hybrid bearings. Using the team's in-depth knowledge of bearing failure, the optimal set of operating data required for early detection will be determined. Through intelligent fusion of the vibration-based and other health monitoring data with model-based techniques, a comprehensive fault detection capability will be achieved. The vibration monitoring approach will be adapted from the existing ImpactEnergyT processing suite developed by Impact over the past several years. This suite consists of higher frequency bandpass demodulation and sensor resonance processing techniques that have been demonstrated on hundreds of data sets to produce early indicators of bearing component failure. The methods proposed produce indications well in advance of conventional Fast Fourier Transform (FFT) bearing fault detection approaches, which may not "see" the fault until it is near catastrophic failure especially in mechanically complex systems with significant "normal" noise. In addition, up-to-date assessments and predictions of the ceramic bearing's remaining useful life for use in automated maintenance systems will also be pursued through the utilization of these multiple sources of engineering information. |

| Title: | High-Speed Machining of Titanium Alloys Using Indirect Cutting Tool Cooling |
| Abstract: | The complexity of titanium (Ti-6Al-4V) firewalls and bulkheads for the V-22 rotorcraft demand the development of new, innovative fabrication technologies that enable high-speed machining (HSM) for affordability. Creare proposes to develop a novel, indirect cutting tool cooling system that will enable the increase of the material removal rate (MRR) by 500% or more for titanium milling. Such an increase in the MRR dramatically reduces the processing costs. For example, we have projected that our system would save approximately $800,000 per year in manufacturing cost for a titanium rotor yoke. Because our solution prolongs tool life, the resultant use of sharper tools will reduce the induced residual stresses in the machined part, improving fatigue life. Our innovation is readily integrated with existing machine tools, minimizing initial capital costs. Thus, our solution is effective, affordable, flexible, and easily integrated with current manufacturing operations. |

| Title: | A Novel Low Cost Approach to Milling Titanium Firewalls/Bulkheads |
| Abstract: | Titanium is one of the more difficult metals to machine economically because of it's combination of high cutting strength, low thermal conductivity and tendancy to react chemically with the carbide cutting tools. The proposed machining approach side steps these material problems by using abrasive waterjets to perform controlled-depth milling. Waterjets are commonly used to cut through titanium and other materials but milling to a controlled depth is a new process that holds great promise for high material removal rates and very low-cost production. The process is applicable to wide range of alloys and geometry and the goal of the proposed work is to demonstrate that it can be economically applied to the V-22 firewall/bulheads. |

| Title: | High-Speed Machining of Thin-Web, Large-Pocket Ti-6Al-4V Firewalls/Bulkheads |
| Abstract: | High performance aircraft structures have strict requirements regarding weight, strength and fatigue. The unitization of structures provides reduced labor costs, part count and improved quality while achieving desired weight requirements. Since firewalls are not part of the primary structure, they are typically made of built-up assemblies of thin plates, maximizing weight reduction. Chemical milling (CM) is used to create pockets however, this can be expensive, time consuming and environmentally unfriendly. Progress has been made in applying high-speed machining (HSM) techniques to titanium components via dynamic analysis, system stiffening and improved tooling. Yet application to firewalls is challenging since HSM can result in part distortion and unfavorable stresses not alleviated with shot peening. We will apply our innovative, scalable HSM process utilizing proprietary thermal management techniques in combination with machining modeling to V-22 firewalls. Teaming with Bell Helicopter, the monolithic design will result in dramatically reduced cycle time, cost, part count, and reduction or elimination of CM. The design of experiments testing will establish process boundaries and web thickness capabilities. Dynamic response analysis of the machine tool structure will identify appropriate stable process operating windows. Assessment of residual stresses and forces on part distortion will be made via model analysis. |

| Title: | Autonomous Air Vehicle for Remote Standoff Sensor Deployment Capable of Using Sonobuoy Launchers |
| Abstract: | Dara Aviation and subcontractor ILC Dover propose to draw upon their combined expertise in manufacturing small UAV platforms and inflatable wings to develop an integrated air platform for low-observable, remote standoff deployment of sensors. In its stowed configuration, the integrated air platform (dubbed the "Monarch") and sensor package would have the same envelope as a standard A-size sonobuoy, and could be deployed from any existing A-size sonobuoy launcher, such as the launchers installed on many P-3 Orion aircraft and SH-60B Seahawk helicopters. After deployment, the Monarch would sprout inflatable wings and a folding horizontal tail. It would navigate autonomously to its target location, primarily gliding but also relying on a small motor. The Monarch could be used for standoff deployment of standard F, G, or A/2-size sonobuoies, or standoff deployment of other self-contained canisters of the same size carrying other types of sensors. The Monarch would not need to be deployed from sonobuoy launchers either - it could be mounted to the underside of an aircraft or UAV wing and air dropped. By employing an inflatable wing and small motor, the Monarch would autonomously carry a sonobuoy or other sensor suite up to 50 miles away with low observability. |

| Title: | Precision Aerial Delivery of Sonobuoys (PADS) |
| Abstract: | The PADS device couples to an existing A/2-to-G-size sonobuoy to provide significant stand-off delivery range. The combination of PADS and sonobuoy conforms to A-size mass and geometry and permits current ASW hardware and operational concepts to be employed for deployment. When launched from high altitude, PADS deploys wings and control surfaces to become a precision air delivery platform with a stand-off range in excess of 50 nm. At 200 feet above the water, the sonobuoy is jettisoned from PADS and describes a conventional low altitude, parachute assisted water entry, followed by underwater sensor deployment. The PADS air vehicle then enters the water and sinks. Phase I development focuses on design of the delivery vehicle, control system and the interface with the sonobuoy payload. Team member Sparton Electronics shall provide sonobuoy interface and operational expertise for PADS development. Programmable flight path via the GPS driven autopilot permits mission flexibility for maximum covertness. Delivery accuracy of 100 meter CEP is estimated. Flight vehicle hardware, selected for the combination of performance and low unit cost expendability, is derived from extended range, compact carriage technology development programs at KCI for Air Force air deployed munitions, leveraging available Navy R&D funding while minimizing risk. |

| Title: | Multi-Source Vertical Obstruction Generation |
| Abstract: | In support of low flying air vehicle missions, the Navy seeks improved capabilities to detect automatically, geo-locate, and determine the height above ground of vertical obstructions over operational areas. Of importance is the ability to assess the horizontal and vertical accuracy of detection results and detect obstructions above specified heights. The solution must be able to process and fuse various inputs, including multi-source imagery and elevation data. Accordingly, we propose to research and develop an innovative system to perform these functions, tentatively named: "VertiVision"; and particular emphasis is on support to the Tomahawk Cruise Missile Program. Of prime importance are: 1) A mathematically rigorous capability that can detect vertical obstructions, with emphasis on manmade objects such as buildings, towers, and similar features. 2) A capability to ingest and fuse multiple data sources, to include commercial, national, and tactical and leverage sensor model parameters to ensure maximum modeling precision; 3) A capability to accurately determine the height(s) of obstruction(s) as per mission requirements; and 4) A method for geo-locating the obstructions and making such output compatible with Navy mission planning objectives. Commercial and defense marketplaces are demanding solutions of this type, which suggests an eventual marketable solution should do well. |

| Title: | Multi-Source Vertical Obstruction Generation |
| Abstract: | Cultural development often results in features that obstruct visual and RF view sheds and can constitute obstructions to flight paths for airports and operational missions. Tools are needed that provide for rapid assessment of vertical obstructions for operations worldwide. These tools should be capable of extracting data from diverse imagery sources and assimilating the extracted information together with existing geospatial databases to create new vertical obstruction databases. The proposed research will build on prior research into the automated extraction of digital elevation models and three-dimensional cultural feature extraction. This prior research was conducted to support precision-guided munitions mission planning and precision terrain aided navigation (PTAN) and utilized a broad range of imagery sources including digital point position database (DPPDB). New research will also explore the use of multi-spectral to assist in the feature extraction task. Research will be conducted into fusing multiple data geospatial database sources to create the vertical obstruction database. The goal is to create a tool that can ingest imagery and data in industry standard geospatial database formats, automatically extract vertical obstruction data based on operator input parameters, and export this data into formats that can be used by industry standard geospatial database tools. |

| Title: | Multi-Source Vertical Obstruction Generation |
| Abstract: | TSC will develop innovative methods to automatically extract Vertical Obstructions (VOs) from multiple sources of remotely sensed imagery. Initial estimates of the locations and heights of VOs will be extracted from Interferometric SAR (IFSAR) based DSMs using a modified version of TSC's existing Automatic Vertical Obstruction Detection (AVOD) program. The VO locations and heights from AVOD, which can be significantly in error due to the phenomenology associated with IFSAR sensors, will automatically be refined using photogrammetric techniques applied to stereo photography pairs. Attribution of the VOs will also be performed. The resultant VOs are expected to have very accurate horizontal and vertical estimates, and should include all of the VOs visible in an area of interest. TSC will also develop accuracy estimates for the VOs based on the characteristics of the sensors used, and will performed a validation of the VO extraction process using GFE or TSC in-house datasets. Approaches for merging the extracted VOs with existing datasets will also be explored in Phase I. TSC will leverage its experience in photogrammetry, deep understanding of SAR and IFSAR phenomenology and processing from numerous DoD R&D efforts, as well as experience with commercial IFSAR platforms including Star3i and GeoSAR. |

| Title: | An Adaptive Data Fusion and Analysis System |
| Abstract: | This project develops an adaptive data fusion and analysis system to intelligently process, analyze, combine, and abstract useful knowledge from heterogeneous test data sources aboard aircraft/ship by integrating evidence theory, fuzzy logic, plausible reasoning, and dynamic probabilistic networks. Evidence theory serves as a rule induction and knowledge extraction process. A fuzzy clustering procedure extracts information from the original data sources. A plausible reasoning module permits the synthesis of knowledge acquired from different sources and performs causal inference processes to enhance decision aid processes. Dynamic probabilistic networks serve to maintain and update the belief state over time, providing update information for optimal decision making. The proposed intelligent information fusion and analysis system not only takes advantage of innovative individual methodologies but also, more significantly, emphasizes the synergism among all subsystems to assure the overall performance of the information fusion and analysis system. The end product is a commercial software package, An Adaptive Data Fusion and Analysis System, which will dramatically increase the productivity of organizations involved in data management, data mining, data fusion and analysis, and structure and pattern extraction from huge databases of test aboard aircraft/ship. The effectiveness of the proposed techniques is demonstrated on a fully integrated prototype module at the end of Phase I. |

| Abstract: | Testing and Evaluation (T&E) is crucial in determining the operational limits of air vehicles aboard various classes of ships. The cost of conventional testing of air vehicles and ships continues to escalate in a world of tightening project budgets; therefore, the required flight testing time must be decreased by pursuing efforts which optimize the use of existing and future data and that support other approaches such as analytic models and wind tunnel tests. The proposed work will create an intelligent data retrieval and analysis tool which supports real and virtual testing of aircraft and rotorcraft aboard various classes of ships. The tool will assist the T&E engineer in the development and implementation of test plans for the evaluation and certification of aircraft and rotorcraft both in and out of the vicinity of ships. It will operate over a network allowing geographically dispersed test team members access during all test phases, and it will provide access to externally distributed data. The proposed tool will incorporate a knowledge-based system to identify and evaluate relevant data sets pertinent to a specific task, and data query methods will be used for data extraction. |

| Title: | Low Friction Coefficient Electroplated Solid-Lubricant/(WC)Ni Nanocomposite Coatings for Transmission Gear Surfaces |
| Abstract: | The US Navy seeks none-line-of-sight deposition technologies to produce gear coatings to meet the Navy~{!&~}s loss-of-lubricant requirement. Current rotary platform drive trains, coated with black oxide, barely meet the loss-of-lubricant survivability requirement, and consequently require an expensive auxiliary lubrication system adding additional weight to the drive system. Inframat Corporation proposes to demonstrate the feasibility of generating a high performance nanoparticle strengthened Ni nanocomposite gear lubricant coating which exhibits high lubricity. A solid lubricant consisting of Fe3O4 nanoparticles will be electrochemically co-deposited in a Ni matrix. To further increase the wear resistance of the nanocoatings, a small fraction of WC (5-10%) nanoparticles will be added to this nanocomposite system. The proposed program will (1) prepare colloidal bath compositions containing Fe3O4/(WC) nanoparticles in a nickel solution, (2) deposit Fe3O4(WC)/Ni nanocoatings suitable for low friction coefficient gear surfaces, and (3) conduct tests to evaluate coating feasibility including coating uniformity, adhesion, microstructure, hardness, friction coefficient and wear characteristics under projected gear to gear tooth contact stresses and pitchline velocities. The proposed program builds on Inframat~{!&~}s extensive experience in self lubricant and nanocomposite coatings. The proposed lubricant nanocoating is expected to exhibit high adhesion strength, low friction coefficient, and prolonged service with low maintenance cost. |

| Title: | Trimetasphere Nanomaterials as Friction Coatings |
| Abstract: | Of significant interest to the Navy are low coefficient of friction gear coatings. Certain military platforms have a run dry requirement that covet survivability of gear coatings in lubrication-starved environments. Current material systems (e.g. black oxide coatings) do not meet the loss-of-lubricant survivability requirement and require an expensive auxiliary lubrication system. Desirable properties targeted by Luna's Trimetasphere coatings include non-line-of-sight deposition, excellent adhesion as coated and under stress, low coefficient of friction, and ability to be used on a variety of substrates. The objective of this proposal is to develop an innovative low friction coating that has the capability to continue to provide lubricity for a specified period of time, even if there is no gear fluid lubricant present. In this proposal, Luna will produce, manufacture and characterize our Trimetasphere coatings for use as low coefficient of friction gear coatings. Specifically, Luna will investigate the Trimetasphere coating composition, uniformity, and microstructure as well as assess the Trimetasphere coating physical characteristics (e.g. wear, hardness, adhesion, and thermal stability). As the phase I program progresses, Luna will solicit input from the Navy to assess and determine the applicability of developed Trimetasphere gear coatings for specified naval aircraft applications. |

| Abstract: | It is proposed to apply the capabilities of an award wining integrated life prediction software to a Ceramic Matrix Composite (CMC) nozzle. Previously verified on (CMC) combustor/blade-track, the software will perform: 1) material characterization analysis of 2D/3D CMC architectures at the constituent level to predict suitability of newly available CMC materials to their application, 2) material uncertainty analysis and sensitivities of mechanical properties to show the variation in the intensity of potential failure modes, 3) progressive failure analysis predicting critical damage events, failure modes, inspection points/intervals, fracture paths, and life cycles based on micro-crack damage evolution, and 4) life uncertainty analysis and life extension under all operational conditions including the effects of oxidation, extreme thermal environments, and manufacturing process anomalies/variabilities in voids, defects, textile-architectures, and ply-angles. This life prediction code is capable of evaluating CMC structures under static, dynamic, impact, creep, thermal, low/high cycle fatigue, and random power spectral density loads. The life prediction software will be validated using COIC-Oxide/Oxide, and GEAE-melt-infiltrated SiC/SiC coupon test data, and with documented uncertainties under static, creep, and fatigue load-spectra. Life prediction for nozzle design will reveal: Multi-site damage initiation/propagation locations, residual strength, micro-crack-density, and virtual non-destructive evaluation/inspection monitoring via exhausted energy release rates. |

| Title: | Design and Life Prediction Methodologies for Weight Efficient Ceramic Matrix Composite (CMC) Propulsion Components |
| Abstract: | Ceramic matrix composites (CMCs) are being developed for the exhaust nozzle of the Joint Strike Fighter (JSF) because they offer significant weight reduction and high temperature capability. The use of CMCs in JSF components, however, is hampered by the relative immaturity and unproven nature of design methods and life pre-diction theories. Materials Research & Design (MR&D) is proposing to develop Design and Life Prediction Methods for CMCs as a Phase I SBIR program. The program will initially focus on SiC/SiNC composites and environmental variables representative of flaps and seals on the exhaust nozzle, but the theory will be applicable to other CMC ma-terials and other propulsion components. The proposed program will be performed a team of MR&D, COI Ceram-ics, and Southern Research Institute and will include theoretical and experimental tasks. Phase I will include tasks on micromechanical model development and life prediction, material fabrication and characterization, and compari-sons of predicted and measured lifetimes. A literature review will assess the present state of the art in both modeling methods and properties of degraded CMCs. The micromechanical model will be based upon the Phase Average Stress theory in which the properties of the composite are directly related to the environmentally dependent proper-ties of the fibers, interface, and matrix.
