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:Fiber Optic Splice
Abstract:We propose to develop a new fiber optic splice that is designed for military and aerospace avionic applications. The purpose of the Phase I program is to demonstrate the feasibility of our proposed approach. The new fiber optic splice is intended to meet stringent military and avionic requirements and provide long-term, reliable optical connectivity for repaired fiber optic cables. The new splice will meet or exceed these technical requirements: a) wide operating temperature range (-75 to +200 C or -40 to +120 C), b) low optical insertion loss (< 0.5 dB), c) high mechanical strength, d) small splicing equipment foot print, and e) elimination of spark hazards associated with splicing equipment. Emphasis will be placed on developing a thermally balanced splice that can maintain a low insertion loss in a temperature-cycled environment.

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 -40C to 100C. 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.

Title:Superlens Integrated Packaging for Ruggedized Laser Diode Module in Wavelength Division Multiplexed Networks
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.

Abstract:Alpha Omega Electromagnetics LLC. has proposed a novel, bandwidth-tunable array radiating element architecture. This technology will support advanced technology multi-octave dual-polarized radar or electronic warefare-based phased array radiating apertures. In this SBIR program, it is our objective to demonstrate the viability of this concept through an electromagnetic-simulation based investigation using AOE's proprietary 3D infinite scanning array FEM field solver software. Upon selecting the most promising element topology, we will perform a baseline radiating element design and through electromagnetic simulations characterize its radiation bandwidth, scan and polarization performance in the array environment, thereby demonstrating the merits of the newly proposed radiating element architecture.

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.

Title:Wide-band 2-D Electronically Beam-Steering Radiating Aperture
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 200C 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.

Title:Small Multi-Decade Communication Antenna
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:Noncooperative Tracking of Underwater Vehicle
Abstract:A novel non-acoustic shallow-water tracking concept for underwater vehicles currently under development is further refined to the point where system performance capabilities and limitations can be reasonably predicted and system design tradeoffs quantified. The method consists of unique polymer composite micro particles that are activated by the vehicle's wake and mark it's track on the water surface. Airborne optical sensors subsequently detect the marked track. The proposed work will extend this concept from feasibility in a laboratory environment to practical field application.

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.

Title:Continuous Active M-sequence Sonar (CAMS)
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.

Title:Improved Crashworthy Seating for Naval Helicopters
Abstract:This Phase I program would examine the feasibility of developing a lightweight energy-attenuating troop seating system 10 pounds or less that meets naval injury tolerance standard. The effort will focus on designing and examining the major load-bearing components of the seat to determine which components might be optimized through the use of lightweight materials. Also, ArmorWorks will develop and evaluate differnet energy absorbing concepts that have been suggested and developed to provide the best possible crash protection to occupants weighting 140-240 pounds. Emphasis will be placed on efficient energy attenuation processes requiring possible shorter strokes, and keeping weight of energy absorber system to a minimum to protect all troop population. This SBIR Phase I will yield a quantitative set of seat design guidelines and models that can be implemented to military helicopter and civil rotorcraft. Later, Phase II studies could include more engineering development, prototype seat static, and dynamic crash impact tests.

Title:Architecture and Tool for Self-Evolving Maintenance and Operations Reasoning
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.

Title:Distributed Ontogenetic Reasoning System
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.

Title:Self-Evolving Maintenance Knowledge Bases
Abstract:Intelligent Automation Systems, in collaboration with the Georgia Institute of Technology proposes the development of Self-Evolving Knowledge Base architecture. Specifically, this project will consist of 1) Analysis to identify maintenance related issues such as failure modes, criticality, etc for a selected test bed that will comprise of a critical subsystem or component; 2) Systematic knowledge engineering steps to characterize the maintenance, logistics, and inventory related issues, and to elicit domain as well as control knowledge; 3) Development of a novel architecture and algorithms for the integration of the control knowledge of self-evolution for a continuous improvement process in a feedback manner; 4) Development of testing plan to validate and verify the self-evolving architecture on a subsystem or component; and 5) Software demonstration of the framework. This proposal involves a novel artificial intelligence technique of reasoning and learning in episodic manner. This methodology forms the core of what is presented as a comprehensive CATER (CAse-based TEmporal Reasning) solution that will exhibit self-evolution process by improving the performance of knowledge-base by observing the feedback generated from multiple sources, such as maintenance logs, IETMs, inventory footprint, component statistics, etc. The solution has a built in capacity to reduce the uncertainty that is inherent in the PHM and maintenance processes.

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.

Abstract:We propose "Airplane in a Tube" - an unmanned aerial vehicle with folding wings, capable of being launched from a sonobuoy dispensor from any altitude. Using GPS navigation and dead reckoning when GPS is denied, it can glide to a destination, release payload, then using an electric motor and LiOn batteries travel several additional miles before ditching. The airframe is based on Swift, which has successfully flown under electric power after launch from a mortar tube.

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.

Title:Intelligent Data Retrieval and Analysis Tool for the Testing and Evaluation of Aircraft and Rotorcraft in Proximity to Ships
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.

Title:Design and Life Prediction Methodologies for Weight Efficient Ceramic Matrix Composite (CMC) Propulsion Components
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. The Phase Average Stress theory computes average stresses in the fibers, interface, and matrix, which can be related to microcracking, diffusion, reaction, and degradation of constituent properties. This approach has proven successful in metal matrix composites, for example, where the composite properties are controlled by the history and temperature dependent, plastic behavior of the matrix. The experimental effort will address multiple environmental variables including temperature (e.g. 75F, 1500F, 2000F), stress level (e.g. above and below matrix cracking stress), load (e.g. mechanical, thermal, static, cyclic), atmosphere (e.g. air, humidity, salt fog), and time (e.g. 10, 100, 1000, 2500 hours). The Phase I test plan will assess a subset of these environmental variables to both address critical environments and remain within the funding guidelines of the Phase I SBIR program. Tests will be performed on both fiber-dominated and matrix-dominated properties. In addition to providing data to assess the micromechanical model, the test data will augment the existing database and assist on-going nozzle design projects. The comparison between model predictions and experimental results will assess the feasibility of the theoretical approach and provide a logical milestone for transition to a Phase II effort.

Title:Damping Coatings for Gas Turbine Compression System Airfoils
Abstract:New concepts and processing methods are needed to minimize high cycle fatigue and improve the damping behavior of monolithic titanium blades, vanes, and stators in high performance aircraft engines. Ceramic coatings applied by the plasma spray process have the potential to achieve the required damping characteristics. The proposed Phase I project will determine the feasibility of the plasma spray process to produce thin, integrally bonded single and multi-layer metal/ceramic coatings to the surfaces of the airfoils subject to airfoil flutter and resonant stress while maintaining the airfoil's inherent mechanical properties. Secondly, parallel studies will be made to add materials with high damping capacity to the plasma sprayed ceramic coatings. The plasma spray process conditions will then be further refined to optimize the final coating systems for damping effectiveness, resistance to material fatigue, and erosion resistance.

Title:Free Layer Blade Damper By Magneto-mechanical Coating
Abstract:To prevent blade failure, the excited resonant response needs to be attenuated to an acceptable level. Several investigators have presented approaches to suppress blade vibration by providing additional damping through blade dampers. Among them, a surface high-damping magneto-mechanical coating layer, so-called free layer damper developed by the PI, is likely to be more practical. The proposed Phase I efforts include: (1) characterization and identification of magneto-mechanical coating stress/strain dependent nature associated with the damping mechanism at various temperature levels (room-1500 F), (2) development of a vibration testing procedure to characterize the dynamic properties of uncoated and coated beams at various temperature levels (room-1500F), (3) a framework will be developed for the estimation of the effect of static mean stress on damping properties of the coating, and (4) developing an analytical approach for predicting the dynamic performance and the nonlinear behavior of the beams and blades coated with a thin layer coating with thickness < 0.005 inch. In Phase I option, assessment of total fatigue life of the coating materials under bending condition will be conducted. In addition, the corrosion of the coating material will be examined thoroughly. Finally, a new nanotechnology will be developed to systematically organize and manipulate stress-induced irreversible movement of the coating magnetic atom domain walls to achieve high damping and damage resistance.

Title:Composite Lift Fan Driveshaft (CLD)
Abstract:The titanium JSF Lift Fan driveshaft is highly loaded, experiences significant fatigue loads and is carefully designed to dynamic requirements. The Composite Lift Fan Driveshaft (CLD) developed in this program offers significant weight savings and fatigue performance benefits. Two processes are particularly suited to this application - automated braiding and Ultrasonic Tape Lamination (UTL). NAVAIR is applying automated prepreg braiding to F/A-18 E/F airframe production, including a material qualification property database. This substantially reduces risk and cost for the CLD described herein. UTL is used in highly loaded composite driveshafts for a large Navy motor using a novel end fitting attachment featuring a crenulated tooth design. Joint load capacity 28 percent higher than required in the CLD has been demonstrated. In other composite tubular structure, end fitting joints and tubes have been successfully tested to loads up to 1.9 million lb. In this program design trades and structural analyses shall be performed after definition of detailed requirements. Particular design attention is focused on an efficient and lightweight crenulated joint. Tube sections shall be fabricated and structurally tested to validate design and process details. Rolls Royce will collaborate on this effort to maximize opportunities for technology insertion on the JSF. (P-040184)

Title:Innovative Materials and Designs for Joint Strike Fighter Lift Fan Drive Shaft (MSC P1A12-401)
Abstract:The goal of this SBIR project is to develop and demonstrate lightweight, low cost, drive shaft concepts for use in high performance rotating engine drive systems, with specific focus on the STOVL lift fan system. The product of Phase I of the SBIR program outlined in this proposal will be a lightweight graphite fiber reinforced composite drive shaft and end fitting design that meets the structural requirements of the JSF STOVL system. A proof-of-concept prototype tube will be fabricated during Phase I to establish manufacturing feasibility, verify weight estimates and support cost studies. The design concept and manufacturing approach builds on previous research that successfully demonstrated the structural robustness and weight and cost competitiveness of a Materials Sciences Corporation design developed for the V-22 Osprey wing drive system.

Title:High Performance Composite Drive Shaft for JSF STOVL Lift Fan System (1000-414)
Abstract:Triton Systems, Inc proposes to develop a Polymer Matrix Composite (PMC) drive shaft for the lift fan of the Joint Strike Fighter (JSF) Short Take-Off Vertical Landing (STOVL) system. The Composite Lift Fan Drive Shaft (CLFDS) will provide increased fatigue life and a significant weight reduction over the current titanium design. The PMC shaft will meet or exceed the requirements of the US Navy by utilizing the low density, high strength and directional mechanical property control of Carbon Fiber Reinforced Plastic (CFRP), to tailor the performance of the shaft to the specific operational loads. The high stiffness of CFRP can allow the shaft to run longer unsupported distances, reducing the number of bearings required for the system and thereby reducing the weight of the overall drive system. CFRP also has excellent damping capabilities, which can help minimize wear at bearing supports.

Title:Multiplexed Spectroscopy Sensor for Assessing Combustion Instabilities in Jet Engine Augmenters
Abstract:Recent issues with augmenter performance tests including blow-off and intense combustion dynamics that drive strong acoustic waves have necessitated new augmenter designs. In order to validate new concepts, quantitative combustion diagnostics will be required to assess the effect of design alterations. Zolo Technologies, Inc., cooperating with Professor Ron Hanson's group in the High Temperature Gasdynamics Laboratory at Stanford University, proposes a combustion diagnostic sensor system that will be capable of providing the necessary data to validate new augmenter design concepts. The multiplexed spectroscopy sensor (MSS) can monitor combustion parameters such as temperature, temperature non-uniformity, flow velocity, CO2, CO, H2O, O2, and unburned fuel concentration using a fiber-coupled tunable diode laser (TDLAS) system at data acquisition rates of, at least, 100 kHz. The proposed sensor is similar in concept to, but substantively different from, MSS sensors that Zolo and Stanford have demonstrated for SCRAMJET diagnostics at the Wright-Patterson AFB and for application to combustion optimization at coal-fired electric utility boilers.

Abstract:Metron proposes to develop the mathematical theory and associated algorithms for combining multi-sensor data fusion based on Likelihood Ratio Tracking (LRT) with search optimization based on dynamic stochastic programming. We draw on extensive experience in using LRT in various, successful Anti-Submarine Warfare (ASW) applications and search path optimization for controlling a fleet of autonomous unmanned aerial vehicles (UAVs). The coupling of these two methods presents an excellent opportunity for allowing the joint properties of multiple sensors to drive the search planning, and for allowing the physical constraints of the search, as well as real-time sensor reports, to drive the deployment and use of various sensors.

Title:Airborne and Air-Deployed Multi-Sensor Search Optimization
Abstract:Since the Second World War, increased performance has been acquired by investing heavily in expensive new sensor hardware, at the near exclusion of developing new algorithms and tactics to optimize use of sensors in complex environments. The shift toward threats in just such hostile areas demands a more synergistic approach wherein new sensors breed new tactics, and possibly vice versa. The optimization strategies to date either provide precise answers to sensor usage, but too slowly to be tactically useful, or quick answers that are at best suggestive of the proper strategy. SCOUT (Sensor Coordination for Optimal Utilization and Tactics) is a novel approach which combines the best aspects of the most promising methods, and approaches the solution process in a sufficiently general way that its capabilities will be useful for land-based, sea-based, air-based sensors, platforms, and searches, and the much more difficult problem of mixed-environment missions (such as a beachhead invasion). SCOUT adapts previous work with genetic and Bayesian solutions to solve the specific problem of optimally choosing aircraft sensors and flight paths to maximize overall mission performance, while minimizing vulnerability.

Title:Search Optimization for Multiple Airborne and Air-Deployed Sensors using the Adaptive Simulated Annealing (ASA) Algorithm
Abstract:The challenge presented in this SBIR topic is to create a tool that allows an operator to create near-optimal search plans for a given environment, suite of sensors and threat types. Sensor performance, often expressed in terms of a probability of detection, for each sensor type is predicted using the sensor's own tactical decision aid (TDA). This SBIR proposal does not recommend building additional TDAs for various sensors. The primary goals of the proposed work plan are the development of a technique to accurately sum the probabilities of detection from a heterogeneous set of sensors and the application of Adaptive Simulated Annealing (ASA) algorithm to solve the problem of determining near optimal search plans using a user selectable measure of effectiveness. A key strength of this approach is that it can be applied to both over-water and over-land searches. The approach uses the predictions of each sensor's TDA and therefore can be applied to both acoustic sensors and non-acoustic sensors (electromagnetic, electro-optic/infrared, radar and magnetic anomaly detection). The resulting product will generate near-optimal search plans to the mission planner for the predicted distribution of threats, the operating environment, suite of sensors available and user selected measure of effectiveness.

Abstract:Scientific Systems Company, Inc. (SSCI) and Lockheed Martin Maritime Systems and Sensors (MS2) propose to to design, implement, and validate "SPA: Search Planning for ASW", a system that exploits environmental, sensor, and threat information to make maximal use of available sensors for ASW mission effectiveness. This system will account for (1) a variety of acoustic and nonacoustic sensors using real environmental data under a variety of flight conditions (altitude, airspeed, etc.) (2) mutual interference problems when sensors operate simultaneously (3) platform location, capability (speed, ability to turn, sensors carried, etc.), and availability (e.g., deployable sensors such as sonobuoys are limited to storage capacity) (4) a measure effectiveness (MOE) that will include maximized cumulative probability of detection, minimized time elapsed to meet a detection probability threshold, maximized probability of survival, etc. and combinations thereof) and tailor to suit present needs. The Phase I will simulate sets of controlled, but realistic, sensor performance data and evaluate the validity of the proposed concept and will show the value of optimal search planning and the need for joint sensor usage. The Phase II will build a prototype tactical decision aid system. For Phase III, this team will work with the Navy to transition and integrate this system in MMA.

Title:Kinetic Metallization - A Repair Process for Ion Vapor Deposition (IVD) Aluminum
Abstract:Repairs of IVD aluminum coatings are generally not possible because the weak-plasma deposition process requires parts to be coated in a vacuum. Until recent development of the low-temperature Kinetic Metallization (KM) spray process the only metallic processes being evaluated for aluminum coatings on steel have been oxygen-free organic plating (AlumiplateT?), Al-Mn molten salt bath electroplating, and Ion Vapor Deposition (IVD) aluminum. Inovati developed a corrosion protective aluminum composite (AlTransT?) coating that is currently applied to carbon steel racks using the KM powder spray process. It is anticipated that the environmentally acceptable KM process can be used to economically repair IVD aluminum coatings on aircraft components using various nonhazardous powder feedstock materials including a composite blend of aluminum with a transition metal called AlTransT?. The object of the Phase I research is to develop one or more nonhazardous coating formulations using the low-temperature KM spraying process as a means of depositing an economical and high-quality corrosion-resistant metallic coating on high-strength steels. This environmentally compliant coating will be used as a replacement coating for cadmium brush plating currently used to repair IVD coatings on military aircraft.

Title:Plasma Processing for Repair of Ion Vapor Deposited (IVD) Aluminum Coating
Abstract:Ion vapor deposited (IVD) aluminum coatings on aircraft and navy ship board components inevitably get damaged and require repair. A nonhazardous repair to brush cadmium plating is required that meets performance requirements of the IVD aluminum. A unique plasma energy source process that does not require any solutions can apply adherent pure aluminum as well as aluminum base alloy repair coatings to damaged IVD aluminum without melting or adversely affecting the IVD aluminum coating. The process has been cursory demonstrated and can be automated such that highly skilled specialty trained operators are not required for field repair. The process will be further developed in Phase I along with composition optimization of the pure or alloy repair coating, coated specimens corrosion and other screen tested, and sample coated specimens provided to the navy. An automated design for coating repair will be produced in Phase I for construction and demonstration in Phase II.

Title:Method for Repairing Damaged Ion Vapor Deposition (IVD) Aluminum Coatings
Abstract:This Phase I effort will try to develop a method for repairing damaged IVD aluminum coatings instead of the brush cadmium plating currently used by Navy. Due to the toxic nature of cadmium, the new method with non-hazardous operation procedures mainly consists of cold spraying and shotpeening (CSS) by using aluminum as the coating material, which includes the steps of: (1) damaged area cleaning by sandblasting; (2) coating preparation by cold spraying specially processed aluminum powders; (3) shotpeening the coated area to densify the coating; (4) thickness correction and chromate conversion coating if necessary. The new coating will meet or exceed the performance of the coating it repairs, and has a good bonding strength with the substrate and adjacent material, and also provide an adhesive base for subsequent organic coatings. In order to realize this method, an apparatus will be designed and fabricated during this Phase I project. The apparatus is a compact and integration system, containing three functions: sandblasting cleaning, cold spraying and coating densification. It is also lightweight and easy to transport to any place where the repair is needed. The whole repair process will be done in a few minutes, depending on the size of the damaged area.

Title:Lease Based Mobile Authentication
Abstract:The Navy seeks to increase the authentication of mobile communicating nodes such as war fighting ships and aircraft. BCI proposes a novel Lease Based Mobile Authentication scheme that requires two authentication steps before permitting new entities to join a network, or existing entities to renew their membership. The Local Authentication step involves challenges by nodes co-located with the entering node to verify its identity and position. This is followed by Network Authentication that uses the approximate location information of the entering node as one factor in a decision to accept or reject the request to join the network. Following Network Authentication, a temporary lease is granted to the node to allow it to communicate. The overall result is highly secure authentication, without a dependence on GPS positioning information, or any centralized decision-making authority. The overall goal of this project is to demonstrate the performance and potential of the proposed Lease Based Mobile Authentication technology.

Title:Strong Location-Specific Authentication for Mobile Users and Devices
Abstract:The effort proposed here by the DAT team will investigate and quantify the use of DAT's strong authentication system for the control of access to wireless networks. The DAT system fuses 7 different credentials into an incalculable and continually dynamic authentication system. Although the specific operation of the system in the wireless environment will developed in the course of the proposed SBIR Phase I task, a preview of the specific credentials that must all be co-resident before access is authenticated can be prepared from the working DISA system. These credentials and their use (described below in further detail) include: 1. User specific information, such as biometrics. 2. The processor ID number on the user's authorized computer. 3. The volume ID number on the user's authorized ID number. 4. The DAT electronics ID number. 5. The LSDFTM historical table of physics based secrets (captured in the past by the user each time he logged in.) 6. The user's location, based on the use of the location awareness component of the DAT system to determine whether or not the user resides at a pre-approved location. 7. The correct sliding port target for access. DAT believes that a physics based authentication system is ideally suited to an immediate, revolutionary and significant strengthening of wireless network systems with minimal impact on costs and current method of operation.

Title:Multipath Encryption and Authentication System
Abstract:We propose to develop a novel, fail-proof method by which wireless users' will be able to verify each others identity based on details of the physical environment only accessible to those users. The approach allows fairly non-complex and compact hardware apart from the radios. It is based on the fundamental property of RF waves that RF waves are invariant under time reversal. The idea is most easily explored with impulse radio (Ultra Wide Band, or UWB), but also extends to conventional narrowband communications. IAI has extensive experience with the characterization of UWB multipath signals. This proposal explains some preliminary experiments that demonstrate this idea. During our Phase I effort, we will measure UWB multipath signals by using UWB radios in scanning receiver mode and develop a thorough characterization of multipath signals for some environments of interest. After developing algorithms to distill a robust (under small experimental variations of the signal) password from the multipath signal, we will incorporate these algorithms with the radios' own algorithms. By the end of phase I, we will demonstrate our complete hardware and software for this application.

Title:Laser Repair of Compressor Blades
Abstract:Modern aircraft are constantly required to operate in harsh conditions, which result in accelerated turbine engine compressor blades damage by erosion or by foreign object debris. This damage causes loss of engine performance, increased fuel consumption, and damaged compressor hardware, resulting in decreased safety and mission performance. A significant effort is being made to find a cost effective and structurally sound method of blade repair. Conventional repair methods, such as tungsten inert gas welding (TIG) or laser powder deposition processes produce excessive heat input creating an excessive porosity between the build-up passes, degrade original parent metal properties and results in costly rejects and scrapping of components. The proposed advanced manufacturing process offers a low heat input metal deposition with a reliable metallurgical bond, while combining pre-and post-deposition machining operations in one automated repair process and machine. This promises to revolutionize the cost and time of repair of these complex geometry components. Recent advances with PMDT low heat input flat wire metal deposition encompasses the metal deposition and pre-and post machining of components into one integrated system. Implementation of this technology would have significant technical and economic value for a myriad of US Government and commercial industrial applications.

Accompanying processes such as finishing will be assessed. A cost model will be developed, and manufacturing plans established, such that a business case can be made to proceed to Phase II. The outcome will be an assessment of the process relative to traditional means, and an identification of methods to successfully develop and introduce the technology to the Navy.

Title:Next-Generation Catapult Slot Width Measuring System
Abstract:Aircraft carrier catapults must be routinely inspected to ensure the safety of the aircraft being launched and the ship itself. One of the key inspection parameters is the slot width ( 1.4") in each of the two steam driven piston cylinders, which must be measured to an accuracy of better than A0.001" over the 350 foot length of each tube. We propose to develop a next-generation catapult slot width measuring system that uses wireless operation and a non-contract slot width measurement to minimize size, weight, and complexity while maintaining reliability and accuracy. We will base our design on commercial off-the shelf (COTS) components to facilitate future changes and enhancements, and the proposed system will fit within a single carrying case. It will be easy to set up and use since it will not utilize any cable reels and will employ a modern user-friendly software interface. In Phase I, we will prove the feasibility of our approach by demonstrating key aspects (e.g., accuracy and wireless operation) under prototypical conditions. In Phase II, we will construct a complete prototype and conduct field tests on actual catapults.

Title:An Innovative Approach to Cylinder Slot Gap Measurement for Aircraft Carriers
Abstract:Foster Miller's Slot Measurement System (SMS) is a rugged, reliable, accurate and easy to use system for aircraft carrier catapult cylinder slot measurement. This system will combine Foster Miller's proven robotic technology experience with its carrier catapult design experience to achieve the optimal system for use by carrier personnel. The system consists of three major subcomponents; the vehicle (including measuring system), the base controller (including the Human Machine Interface or HMI) and the tether. The drive section uses the slot of the cylinder itself for traction and pulls the measurement device with it through the slot. The measuring device will employ a modified pin-gauge tool combined with an LVDT (linear variable differential transducer) or similar sensor inside to achieve the measurement accuracy required for this application. A microcontroller on the vehicle will control motion and continually monitor the gap distance. The HMI will employ a PDA allowing the operator to monitor the vehicle and gap information in real-time and store that data. A microcontroller on the vehicle will control motion and continually monitor the gap distance. (P-040200)

Current equipment is unreliable, bulky, difficult to use and maintain, and prone to measurement errors and frequent failures. PSI has recently developed a "Gap Gear" prototype under an internally funded research and development (IR&D) program that was completed in the fall of 2003. The design incorporates advanced features and capabilities that were identified during discussions with fleet operators and technical experts interviewed aboard the USS Kennedy in the summer of 2003. Through its IR&D program, PSI has developed and demonstrated an innovative design based on proven COTS technologies and has fabricated and tested a prototype catapult gap measurement system that affordably addresses the key system shortcomings observed in the current instrumentation. In the proposed Phase I and subsequent Phase II SBIR programs, PSI shall leverage the results of its IR&D effort, and will fully develop an aircraft launch catapult gap measurement system to meet the catapult gap measurement requirements of the US Navy Catapult preventative maintenance programs.

Title:A Fidelity Analysis Tool for F-35 Joint Strike Fighter Training Systems
Abstract:In many cases, flight simulator quality is equated to the physical characteristics of hardware/software contained within a system. In conjunction with this practice; the term .fidelity" is often used to express the compiled performance of various simulator components. In view of these comparisons between mechanical parameters and software performance (for determination of simulator quality) it|s not unusual that fidelity requirements are often based upon how much technology an organization can afford, instead of assessing the level of technology needed for an optimal training experience (Roza, 1999). Rather than base fidelity requirements solely upon inanimate parameters (optical, mechanical, and piezoelectric) SDS proposes development of objective human compatibility (bioengineering) standards for a more insightful definition of simulator fidelity. To achieve this goal, specific aeromedical parameters will be integrated into bioengineering standards that define the level of compatibility between inanimate simulator components and human perceptual-cognition systems. Specifically, SDS proposes development of simulator fidelity standards based upon known bandwidths of aviation biometrics that are related to sensory and cognitive functions. Among the variables planned for testing are aviation-sensory-spatial-reflexes (e.g., opto-kinetic cervical reflex, torsional opto-kinetic nystagmus, and vestibular ocular reflex shifts) and stick control bandwidths defined by the frequency weighted task complexity index.

Title:A Fidelity Analysis Tool for F-35 Joint Strike Fighter Training Systems
Abstract:The F-35 presents many training challenges for both aircrew and maintenance due to its new and unique systems as well as multiple configurations. The F-35 Integrated Product Team is looking for innovative procedures and software tools that will aid in the Instructional System Design (ISD) of training devices to include the selection of the most appropriate levels of fidelity and the process by which the specifications will be developed. Based on its extensive experience VSAT is proposing an automated Fidelity Identification and Specification Development Process that begins with outputs of the ISD Process and descriptions of aircraft subsystems. The importance of the subsystems to each task along with the subsystem fidelity required for that task will be identified. Initially this will be based on interviews with aircraft operators and simulation experts, but full automation will be investigated in Phase I. This data will result in a preliminary fidelity baseline that prioritizes detailed requirements development. Detailed specification and verification requirements will be derived from the baseline through an automated process assisted by an interactive relational database. The process determines the optimum requirements based on cost, training objectives as well as the overall F-35 configuration.

Title:Advanced Techniques for Verification and Validation of Prognostic and Health Management (PHM) Capabilities
Abstract:Impact Technologies, in collaboration with the Georgia Institute of Technology, propose to develop and implement an advanced, open-systems (OSA-CBM) software simulation environment for Verification and Validation (V&V) of prognostics and health management (PHM) technologies for the F-35 (JSF). The PHM V&V testing environment will include the capability to model sensor signals, fault detection and prediction algorithms, as well as reasoner technologies directly within a dynamic simulation software application. Through the open-systems ability to "plug-`n play" various PHM algorithms into a dynamic simulation environment, the PHM application system under test can be comprehensively analyzed with specific prognostic metrics developed to support PHM maturation and validation over the system's life cycle. A key aspect of the V&V approach is that it will be implemented with the COTS Simulink environment so that all PHM system suppliers will have the capability to access, integrate, test and validate their models and PHM technologies. Specifically, the core innovations of this project include: 1) Developing an open-systems test bench to enable "plug `n play" PHM module integration; 2) Developing performance and effectiveness metrics for fault diagnosis, prognosis and reasoning; and 3) Developing a full dynamic validation of PHM capabilities using statistical techniques, intuitive visualization and animation. By the end of Phase I, Impact will demonstrate the advanced V&V technologies using PHM software provided by JSF subsystem suppliers.

Title:Modeling, Simulation, and Other Techniques to Verify and Validate Prognostic and Health Maintenance (PHM) Capabilities
Abstract:Scientific Monitoring, Inc. (SMI) proposes to develop and mature an advanced modeling and simulation technology for verifying and validating (V&V) system/vehicle health management (S/VHM) capability. The technology is intended to provide an effective, affordable, flexible demonstration and evaluation environment to mature Prognostics and Health Management/Maintenance (PHM) as well as integrated control and PHM software throughout their product life cycles. The research addresses the following needs: 1) Advanced flight-worthy software such as the PHM or Integrated Vehicle Health Management (IVHM) software are being developed for advanced vehicles like the Joint Strike Fighter (JSF), there is a need to V&V advanced software and continue to mature (improve and update) the software even after it is fielded. 2) V&V is typically the most costly and time-consuming step in the development of flight-critical software due to rigorous safety requirements. Technologies that make V&V more affordable are desired. 3) Traditional V&V is a process that occurs throughout System Design (design-time techniques). Although limited run-time assurance methods, such as the built-in-test (BIT), are used, the risk of the software is high. An integrated design-time and run-time assurance technique is needed to systematically reduce complexity and risk of software development as well as maintain or increase safety margins.

Title:Validation Tools and Data for PHM Technologies
Abstract:Emerging prognostics and health management (PHM) technologies will reduce maintenance costs for military aircraft while improving safety and availability. On the Joint Strike Fighter, software modules supplied by multiple vendors will be assembled into PHM area reasoners. System integrators will need tools and data for evaluation, selection, and testing of these modules. Sentient Corporation, in cooperation with Pratt & Whitney and Purdue University, will develop a PHM V&V toolset for efficient and effective testing using proven methodologies for diagnostic validation along with innovative metrics for assessing the accuracy and uncertainty of predictive prognostics. Ground truth data is also essential to any V&V capability. To maximize access to and utility of existing data, the new toolset will include powerful functions for secure distributed access to archival data. Finally, a Virtual Bearing Simulator will be created that combines general bearing dynamics and fault progression models with application specific finite element transfer function analyses to generate realistic fault vibration signatures and failure progressions. These signatures will allow PHM development to begin at the design stage for new platforms, and will augment operational validation data for deployed platforms. This project will leverage an existing program to develop fault-to-failure progression models that includes a large experimental study of bearing fault signatures and failure trajectories.

Title:Assessing Useful Remaining Life of Lithium (Li)-Ion Batteries After Deep Discharges
Abstract:Global Technology Connection with its industrial/university partners (SAFT, Smiths Aerospace, Penn State University) proposes to develop the algorithms to determine the useful remaining life of lithium-ion batteries after a deeper than nominal discharge Working closely with cognizant JSF office and our industrial partners, feasibility study on whether remaining useful life algorithms can be augmented by accounting for depth and duration of discharges beyond normal ranges will be performed in Phase I. The prototype remaining useful life model parameters necessary to re-characterize current battery health assessments as well as future health predictions based upon depth and duration of discharges experienced during shipping, storage, or abnormal operating conditions will be enumerated. Strategy for collecting information required to update battery health status after deep and lengthy discharges during normal or abnormal operating conditions will be presented. This concept will be further characterized with the data furnished by our industrial partners/customer to demonstrate the feasibility of this concept. In Phase II, we will develop the detailed remaining useful life models to account for depth and duration of discharge beyond nominal levels. Cycle testing of representative cells or batteries to determine remaining useful life as a function of depth and duration of discharges beyond nominal will be conducted. Verification of the data collection strategy will be implemented and that data can be applied to update battery health status within the overall JSF architecture. In phase III, we will implement updated remaining useful life algorithms that address abnormal discharges by making any necessary modifications to software modules within existing PHM/CBM architecture.

Title:Heat Recovery System for Discharged Hot Water into the Sewer System
Abstract:Water heating accounts for approximately 16% of primary residential energy consumption in the U.S. Some water heating energy can be recaptured from the drain water system, but costs and space requirements limit the marketability of existing products. The subject of this proposal is a more compact, lower- cost drain water heat recovery (DHR) device that expands DHR market potential. The technology can include a heat storage capability to recover heat from fixtures that fill and drain asynchronously, such as dishwashers and clotheswashers. Preliminary analysis suggests that an advanced unit can be manufactured with installed costs of $190 to $225 in preferred applications, and can achieve performance that will yield payback periods under three years when paired with electric resistance water heaters. The proposed project is structured to maximize system performance and market potential through analytical studies, engineering design, and product cost reduction. Phase I work will create a sound foundation for subsequent development work by verifying the viability of the design concept, identifying preferred applications and their impact on the design, and providing more detailed evaluations of economic viability.

Title:Innovative Methods for Optimally Mixing a Diverse Suite of Control Effectors for Marine Vehicles
Abstract:As the Navy expands its presence in shallow coastal waters, new technologies are required to address the precise and aggressive maneuvering desirable for many littoral mission scenarios. This translates directly to higher performance requirements for a ship's guidance, navigation, and control system. Current generation control systems for marine applications are characterized by independent control loops designed to use a specific effector/actuator set to achieve maneuvering in a single axis. The aggressive maneuvering required in littoral regions can violate axis- and frequency-separation assumptions inherent in the baseline controller, resulting in cross coupling, undesirable handling qualities, and, in extreme cases, instability. This proposal presents a novel control system architecture to optimally mix the diverse complement of control effectors/actuators available on marine vehicles. The challenges associated with mixing such a diverse set of effectors are addressed through a combination of model predictive control and control allocation techniques developed for aerospace applications. In this approach, commands are found that effectively blend actuators with very different bandwidths while minimizing any cross coupling effects typically seen during aggressive multi-axis maneuvering.

Abstract:A design concept will be produced for controlling the depth of fatline-towed arrays independent of boat speed and tow scope. The system will utilize existing TB-16 modules, and only add to or replace some array components. Depth excursions will be maximized through a combination of lift, weight reduction, and buoyancy addition. The updated system will utilize existing SSN array elements for flushing and retrieval, thru-hull seals, and deck storage hardware. The delivered design package will include concept drawings; component hardware and software specifications, and overall system performance requirements. An optional task is included to generate performance predictions using advanced flow and acoustic computational methods. Array forces, trajectories, vibrations, acoustic sources, and fatigue life will be quantified, and used to insure the concept design meets expectations prior to starting Phase II work.

Title:Depth Control System for Fatline Towed Arrays
Abstract:The ability to control the depth of submarine towed arrays is a tactically desirable capability needed to place the array in the optimum acoustic layer. Discounting submarine maneuvers, there are three basic ways to implement array depth control: control array buoyancy, control tow cable catenary shape (via cable density variations and/or properly oriented lateral force devices), and/or fly the array via a depressor or winged appendages. The Phase I effort will consist of conceptual design and analysis of the two most feasible approaches: 1) controlling cable density, and 2) flyable approach, emphasizing the anticipated towing profile, practical limitations for typical fleet operations, cable termination designs, system reliability, low cost, and manufacturability of each. An overall performance and relative cost matrix will be developed that will identify the best near-term and long-term design approaches. The immediate near-term solution proposed for shallow water operations is a variable density cable consisting of a lightweight (LW) section near the array, preceded by a heavyweight (HW) section. The long-term "flyable" solution proposed uses the aforementioned LW cable to tow the array, which will include deployable, winged lifting surface devices with active controls yielding a completely flyable system with absolute +/- depth control.

Title:Advanced Composite Mast (ACM) for UMM
Abstract:The Advanced Composite Mast (ACM) comprises the Guide Trunk and Fairing Assembly of the Universal Modular Mast. These components comprise 80% of UMM weight and are excellent candidates for composite part replacement. By converting both parts from duplex stainless steel weldments to composite designs, 900 pounds or 20% of the total UMM system weight can be eliminated. Design concepts shall be developed and sized for applied loads and stiffness requirements. Trade studies of weight, cost and manufacturing methods shall be performed such that optimized designs for both components shall be selected and defined in detail. Reliable weight and cost estimates shall then be prepared. A key feature in both components are linear bearings riding in precision slide tracks to guide the double-acting telescoping elements of the UMM. The ability of a molded composite part to achieve necessary dimensional tolerances, surface finish and cycle life (wear) in UMM operations shall be demonstrated via representative test articles with internal molded slide tracks. By molding these features (versus machined in the stainless parts), considerable machining cost can be eliminated, enhancing ACM affordability. KCI shall apply its considerable expertise developing similar, related composite parts for defense and marine applications.

Title:High Fidelity Data Management and Access
Abstract:Advances in submarine tactical systems have led to an exponential increase in archived data from these systems. This data represents a significant opportunity for sailors and decision makers to gain a complete historical record of submarine tactical operations which could prove invaluable for evaluation, reconstruction and training. BKA proposes to conduct research, leveraging advances in grid computing and data warehousing technology, to develop a set of design processes that will lead to building a submarine tactical data warehouse that is scalable and will support large, multi-petabyte databases. Our research approach will focus on developing advances in data warehousing techniques and processes while attempting to leverage existing hardware investments by the Navy. The results of Phase I will be a set of design processes, validated against a test system using a small, representative subset of data, which will be applied in the construction of a prototype data warehouse in Phase II.

Title:High Fidelity Data Management and Access
Abstract:Data collected from modern naval combat systems is increasing at an exponential rate. While these data rates are expected to peak within this decade, the shore infrastructure is ill-prepared to catalog, store, extract, query, or in general to manage this volume of data. Progeny will evaluate applicability of digital archival approaches used in enterprise data warehouses and digital libraries. Arguably, higher media longevity is of low value because current media outlasts the software and devices needed to read the data. While the Navy has expended significant effort to collect tactical data, modern data quality assurance techniques have not yet been employed within these systems to guarantee or even characterize the quality/integrity of the recorded data. Progeny will evaluate modern digital library and E-Commerce approaches to data quality/integrity management to ensure accurate transcription of archived information. Progeny will develop cost effective, executable recommendations to address media and data life issues in the context of this application, design approaches to data cataloging and indexing, and develop in-situ statistical tools to monitor and quantify data loss and/or degradation of data integrity.

Title:A Scalable Real-time Data Management System
Abstract:Current Navy initiatives such as a standard sonar system (TB-29 towed array) for all submarine classes, Integrated Undersea Surveillance Systems and SURTASS ships, and continued development and installation of Acoustic Rapid COTS Insertion sonar systems are increasing the size of archived acoustic data at an exponential rate. This petabyte size growth will further exasperate the usability of the current tape based archives by the community of users in the Navy. Fortunately, as the cost of disk storage declines and clustering technology matures, there is an opportunity to build disk based digital archive systems that are 100 per cent online, thus offering Naval operational benefits such as faster tactical response to intelligence requests, analyst access to data without temporal linear access delays and real time tape data transfer delays. Here, we propose to develop a scalable real-time data management system (SRDMS) for Navy sonar processing applications. Our solution is built upon our scalable disk based distributed Linux cluster archive storage management system technology - Archivas. SRDMS will seamlessly integrate with existing ONI Common Acoustic Sensor Data Exchange. SRDMS will enable the data collected by submarines and their off-board sensors to be available to joint forces and national agencies.

Title:New Approaches for Reducing Helmholtz Resonance in Submarine Structures.
Abstract:A program to demonstrate a Computational Fluid Dynamics (CFD) technology for the prediction of Helmholtz resonance in openings on submarine hull structures is proposed. The program seeks to build upon established technology developed under funding from the US Navy for the modeling and study of cavity flow fields and underwater submarine flows. In the Phase I of the proposed program, technology demonstration and system characterization exercises are proposed, leading to controller development and experimental demonstrations in a water tunnel during Phase II. The computational tools will be demonstrated by validation against experimental data for candidate configurations of interest to the Navy. Computational system characterization leading to controller identification will lead to a Phase II program, which will combine experimental and computational techniques for controller development and technology realization. The proposed technology will enable the prediction of Helmholtz resonance during design phase of new systems as well as aid in the development of controllers for existing configurations. The proposed program combines the expertise of CRAFT Tech in computational disciplines with the pioneering expertise of Dr. Donald Rockwell in the areas of experimental cavity research.

Title:Broad Band Acoustic Modeling of Reverberation for Torpedo Simulators
Abstract:Current torpedo active search and homing performance in shallow littoral regions can be severely degraded by reverberation. Meaningful testing and evaluation of performance in such reverberant environments is best done by high fidelity simulation. This is not only a question of the high cost of in-water testing. Such simulations can provide situations and environments that can be easily changed, a capability that would be essentially impossible for in-water testing. This proposal describes a study with the goal of providing a realistic model of reverberation for torpedo simulators. The aim is to develop a processor that has the potential of providing time series that faithfully and accurately represent the outputs of the individual hydrophones for a multi-beam torpedo sonar receiver. The input to this processor will be a simulation of the acoustic field at the receiver array, as provided by a propagation model such as that in the NUWC WAF (Weapon Analysis Facility). Furthermore, the processor will not be model dependent, in the sense that new and upgraded propagation models will be able to be implemented without overreaching or exceeding the capabilities of the processor.

Title:Parametric Sonar to Enhance Torpedo Performance
Abstract:Navies of the world have recognized the issues of conducting Anti-Submarine Warfare (ASW) in littoral regions since the Falkland Island war (1982). Since that time, the U.S. Navy has aggressively pursued efforts to achieve dominance in the littorals in time of war. Ongoing R&D efforts for torpedos have concentrated on reducing vehicle self-noise, improved tactics, guidance, and control, and improved active and passive sonar. Parametric sonar has never been employed on a torpedo. Advances in array manufacture and supporting electronics now make a multi-modal torpedo sonar that includes a parametric mode realizable. Proposed is an effort to determine how to employ a parametric mode in torpedo sonar using existing torpedo transduction, and determining what changes could be made to baseline arrays to improve the parametric performance. Our approach develops a proof-of-concept for narrow beam parametric sonar that can be used in conjunction with the existing linear sonar systems onboard the torpedo. Because of the unique capabilities that are characteristic of parametric sonar, the steerable parametric beam that we will develop will significantly reduce reverberation, operate in the high noise littoral environment, and improve the ability of the torpedo tactical processor to make correct decisions while seeking a target.

Title:Novel Electric Direct-Drive Actuator for the Universal Modular Mast
Abstract:Existing submarines rely on hydraulic cylinders to actuate masts. For the next generation Universal Modular Mast (UMM), all-electric actuation is desired to reduce system complexity and weight, and reduce costs. A direct-drive solution is especially desirable to avoid backlash, gear noise, and wear, and to be robust under shock-loading conditions. Under a separate program with the Navy, Foster-Miller has demonstrated a novel motor principle which provides 50 times greater torque or force density than existing state-of-the art motors at comparable levels of power dissipation. For the UMM application, Foster-Miller has already produced a preliminary design of a direct-drive linear motor that meets the UMM thrust and stroke requirements and fits within the size envelope of the current hydraulic mast actuator. In Phase I, Foster-Miller would work with the Navy and Calzoni to optimize electromagnetic design, develop preliminary designs for the brake, sensors, pressure-compensation, power electronic and control systems, and prepare a preliminary manufacturing plan. Also in Phase I, Foster-Miller and Calzoni would demonstrate a critical manufacturing step for one of the actuator's components. In Phase II, Foster-Miller and Calzoni will produce a reduced stroke, full-force prototype, and demonstrate smooth, closed loop control of position and velocity. (P-040114)

Title:Shipboard Electrical Energy Management System
Abstract:Upgrading the war-fighting capability of the surface fleet appears to increase electrical load at nearly 2 percent per year. The CV 67 designed generating reserve is nearly consumed now, and could become insufficient in the near future. Adding capacity to the ship now, to meet expanding load demands, can significantly affect cost and readiness. Foster-Miller proposes to make more efficient use of the existing generation capacity, provide an estimated power saving of as much as 20 percent and allow addition of an additional generator to be delayed by improving the individual power equipment efficiency with energy conservation devices and improving overall power system efficiency with a ship-wide power monitoring and advisory system. Foster-Miller's commercialized noninvasive power monitoring system coupled with COTS energy conservation devices provides a solution that can be implemented by ShipAlt/MachAlt procedures. Foster Miller's innovative power system technologies research and JJMA's shipboard system design experience put this team in a unique position to provide a Shipboard Electrical Energy Management System (SEEMS) that can economically resolve the power shortage problem in the CV-67 and be applicable other legacy ships. A study of adding a generator vs. implementing a SEEMS will be performed as part of this SBIR. (P-040100)

Title:Composite Shipboard Ladder (CSL)
Abstract:The Composite Shipboard Ladder (CSL) provides both weight saving and fire resistance for ship Inclined Ladder applications. Composites are used on Navy ship structure like DDX and a significant fire performance database has been developed on these materials. CSL fire resistance is achieved through an innovative construction demonstrated under the Navy Hatch retrofit program. Stringers and treads are made by Pultrusion, the lowest cost manufacturing process for structural composites. Pultrusion continuously produces constant section lineal shapes and is ideally suited to making tread and stringer parts. Two major shipyards have agreed to participate in the program. After detail requirements are defined, design, structural analysis, thermal (fire) analysis, weight estimate and production cost estimates shall be performed. Specific design performance will be a trade between weight and fire survival time. Test panels representative of the tread and stringer construction shall be fabricated for fire testing per UL-1709. Panel stiffness and thermal profile shall be monitored on loaded test articles as fire exposure progresses to determine the useable life of the part in fire conditions. This precious time can substantially enhance crew survivability.

Title:Lightweight FRP Composite Ladders
Abstract:Luna Innovations will be developing lightweight, flame retardant composite inclined ladders for use aboard naval vessels. The proposed program involves 1) designing composite based ladders meeting Navy specifications for shipboard use, 2) producing environmentally sound flame retardant, fiber reinforced polymer (FRP) composites for use as inclined ladders, and 3) making FRP composite parts proving the proposed composite materials have mechanical and fire retardant properties suitable for use in the designed ladders. The flame retardant FRP composites of this proposal are based on a novel method of imparting fire resistance, and the proposed FRP resins have been shown to be self-extinguishing in preliminary tests. The proposed flame retardant offers advantages of being environmentally sound with minimal off-gassing of toxic compounds during combustion. In addition, the proposed flame retardant resins are expected to have comparable mechanical properties with potential improvements in toughness compared with commercial non-flame retardant resins. Luna has also identified a thermoset resin with thermal stability to meet high temperature load requirements. This development will contribute to the Navy's goal of improving shipboard safety while reducing load weight and cost.

Title:Airdroppable High Speed, Low Signature Craft
Abstract:Stationary sensors are deployed in the ocean to provide situational awareness. Although the sensors provide valuable data, they cannot be repositioned as the situation changes. Increased capabilities of unmanned vehicles offer the potential to combine the sensors with the unmanned vehicle to produce a sensor that can be repositioned by the operational commander. In addition, it is desirable to deploy the unmanned vessel from an aircraft, for the vessel to reposition itself at high speed and for the vessel to project low or no signature. This proposal identifies the approach to develop the unmanned vessel from operationally important mission scenarios, to down select to a specific hull design and to define the provisions necessary for the vessel to survive the air deployment.

Title:Bore Insulator Materials for a Naval Electromagnetic Launcher
Abstract:Electromagnetic rail launchers are being designed for future long range naval surface fire support. These projectile launchers operate due to the interaction between the magnetic field and current flow between parallel conductive rails. An electric current accelerates a projectile down the barrel at hypersonic velocities. A high strength insulator is required to separate the energized launcher rails and keep them in position while being subjected to the large temperature fluctuations and mechanical forces. Current laboratory EM launcher insulator materials fail due to inadequate toughness, temperature capability, and wear resistance. Not only are materials required that demonstrate the necessary performance in this unique environment, they also must be manufactured in the necessary size for the application. FMI, with support from Lockheed Martin Missiles and Fire Control-Dallas, proposes to develop a new material capable of being produced as large composite bore insulators, with properties sufficient to withstand the electrical, thermal, and mechanical load expected during use. The composite material will utilize a silica pierced fabric preform partially densified via impregnation with colloidal silica, SiO2. After multiple impregnations with the silica, a high temperature polymer (Tg >500 C) will complete the densification and close off any remaining open porosity.

Title:Mullite Coated Silicon Carbide Fiber Reinforced Alumina-Zirconia Ceramic Composite Bore Insulator Materials for a Naval Electromagnetic Launcher
Abstract:The US Navy seeks high performance toughened electrically insulative bore materials of significant lengths used to separate copper conducting rails in an electromagnetic launcher (EML) for long range naval surface fire support. An EML consists of two electrical conductor rails, a moving element, and an armature. The rails of an EML are supported a certain distance apart from each other by a pair of perpendicular electrically insulative bore pieces. Insulator materials need to be capable of withstanding the severe mechanical, electrical, and thermal environment during launching, thus needs to be tough, have a high compressive strength, minimize thermal expansion, and capable of withstanding sliding contact aluminum and nylon at velocities up to 2.5 km/sec. Inframat proposes to demonstrate the feasibility of exploiting a mullite coated silicon nitride fiber reinforced alumina-zirconia ceramic composite as the bore insulator materials for Navy's EML applications. In this approach, particulate reinforcement toughening induced by nanostructured zirconia, phase, combined with the silicon carbide fiber reinforcement, will significantly improve the fracture toughness and promote the resistance to thermal shock and erosion for the alumina ceramics. The silicon carbide fiber will be coated with a mullite layer to ensure high electrical resistance.

Title:Fiber Optic Detachable Adjustable Power Meter
Abstract:To address the U.S. Navy need for a detachable fiber optic power meter, Physical Optics Corporation (POC) proposes to develop a new Fiber Optic detachable Adjustable power Meter (FOAM), with a detachable optical probe electrically connected to a compact indicator panel. The probe includes a focusing optical element insertable into the adapter/contacting optical connector, and an integrated photodetector. This probe includes a mechanism to adjust to all sizes of Navy optical termini. The indicator panel electronics convert the signal from the photodetector into digital signals for display on an LCD that can be strapped on the wrist or arm. The FOAM will be compact and low-cost, with low optical insertion losses, high accuracy, and mechanical and environmental stability. FOAM is far superior to current meters in functionality, as its probe can work inside interconnection boxes. In Phase I, POC will fabricate a FOAM to demonstrate concept feasibility, test it, and establish performance specifications based on the testing. Anticipated specifications include 0.8 - 1.55 micron wavelength range, operation without jumper fiber cable, power range -80 to 10 dBm, and compatibility with ST, SC, LC, and M29504 termini. In Phase II, POC will develop an engineering prototype that can adjust automatically.

Title:Fiber optic power meter with optical detector in a detachable probe.
Abstract:The US Navy has an immediate and compelling need for a handheld, battery powered, fiber optic power meter with a remote optical detector. Existing handheld meters have the optical detector mounted on the main unit. Such meters often do not fit in the tight spaces found in ships, planes, and other vehicles. A novel fiber optic power meter design with a remote optical detector probe is proposed for use in these tight spaces. This design will address and correct the shortcomings of every other handheld fiberoptic power meter currently available. The detector will employ a universal fiberoptic adapter. This will allow it to couple to any fiberoptic connector. This meter will determine the wavelength and set itself accordingly, eliminating this issue as a potential for measurement error. The detector will be attached to the main meter unit by a flexible, pliable, conduit similar to that used on a gooseneck lamp. Combined with a base that firmly attaches to almost any surface, the detector is easily positioned, and stays in place. The unit will be waterproof and impact resistant. The proposed unit addresses all the current US Navy requirements for a Fiber Optic Power Meter.

Title:Air-cooled High-power Blue-Green Laser
Abstract:CTI's extensive experience with high energy, mil-spec laser systems makes us keenly aware that the environmental controls for such lasers can be larger, heavier, and more power-hungry than the lasers themselves. The next generation of airborne lasers must address this situation head-on in order for dramatic advances in laser technology to achieve widespread utilization. CTI proposes a fresh look at high power green lasers by seeking to remove temperature control requirements from three key subsystems - pump lasers, laser crystal, and doubling crystal. Diode lasers are used as the pump source to obtain the efficiencies necessary in power-limited platforms such as UAVs. Our design process is prioritized by the weight and power consumption goals of the Navy, and utilizes several recently demonstrated innovative CTI technologies that enable compact, high beam-quality, high energy output. Phase I will provide a detailed laser design and critical validation demonstrations. Phase II will design, develop, test, optimize, and deliver a breadboard transmitter for further Navy laboratory testing. The effort will extensively leverage multiple existing CTI programs, including a MARCOR SYSCOM program for surf zone mine detection, that are developing these technologies.

The technical approach to be investigated incorporates novel high-gain laser pump modules in an oscillator-amplifier configuration to produce tens of Watts average power output at 532 nm. Air cooling eliminates the use of liquid cooling fluids in the laser transmitter. This feature results in significant increase in efficiency and reliability and savings in size and weight.

Title:Air-cooled High-power Blue-Green Laser
Abstract:The United States Navy currently is developing airborne mine detection systems (AN/AES-1) that use laser illumination coupled with sensitive electro-optic receivers to find mines in the upper part of the water column. Although the equipment is intended for operation from a manned helicopter, the next generation of such equipment is expected to operate from unmanned aerial vehicles (UAVs). Such platforms are anticipated to provide less payload and power than is available from the current helicopter platform. The single biggest subsystem in terms of weight and power consumption in the current system is the laser and its associated environmental conditioning equipment (ECS). Therefore, we propose to evaluate novel laser design concepts that incorporate: a high-temperature diode pumping (optimized for 50 degrees C or more); an efficient pump head design with optimum coupling to the matching solid-state laser media; distributed thermal load design; efficient and high beam quality cavity; and solid-state frequency doubling to produce 500-540 nm blue-green laser output. The theoretical design including distributed thermal management and the blue-green laser output performance will be predicted using commercially proven modeling software. During Phase I, based on the theoretical modeling, we propose to design, develop and test a proof-of-principle high-temperature, limited energy diode-pumped solid-state laser oscillator head, a scaled down thermoelectric (TE) cooling array, an optimized fin air-to-air heat exchanger platform for the limited energy oscillator as well as scaled down water-to-air heat exchanger and heat distributor/regulator subassemblies. The test data collected will allow fine tuning of the theoretical software models and will assure the scalability of the Phase I design models to support Phase II and Phase III laser system requirements. The finalized Phase I design concept and the theoretical modeling will first support the design, development and production of the Phase II prototype laser system. Phase I program results and validated theoretical modeling for the design should allow the Phase II laser system to have at least 4 watts of 500-540 nm output, at a pulse repetition rate suitable for meeting present AN/AES-1 technology insertion requirements of 100-400 Hz. Additionally, the Phase II laser system will meet all safety criteria established in ANSI Z136.1-2000 for military exempt lasers. Laboratory demonstration of this complete laser system will be structured to demonstrate full functionality over the intended temperature range of 0-120 degrees F (-18 to 49 degrees C). During Phase I and Phase II, additional theoretical software models will be developed for the design and development of a larger scale amplifier network which will show how the developed technology can be scaled to 40 watts of blue-green output at higher pulse repetition rates of up to 400 Hz, suitable for meeting AN/AES-1 technology insertion requirements. Although diode-pumped lasers with the properties described above have been demonstrated for R&D and limited commercial applications, considerable development is especially required to build the robust systems that would be needed for the Phase III effort to include the laser as a P3I replacement for the current laser in the AN/AES-1, and/or for the follow-on program for operating an AN/AES-1 capability from a UAV. Our SBIR Phase I proposal incorporates all state-of-the art laser and thermal management technologies and it is intended for design, development and production of a solid-state blue-green laser that can meet the needs of such air-cooled blue-green laser system requirements of the United States Navy.

Title:Advanced Forward Looking Sonar for Unmanned Vehicles
Abstract:This Phase I proposal is to establish the feasibility of developing an advanced technology forward looking sonar to enhance the intelligence, surveillance and reconnaissance (ISR) mission capabilities for unmanned underwater vehicles. The proposed approach will combine a proven model-based array signal processing technique along with an innovative, flexible, array-based sonar electronics architecture to provide an FLS core technology capable of providing wide field-of-view, three-dimensional acoustic images of the seafloor and water column while consuming less power and physical space than existing 2D obstacle avoidance sonars. The approach will use spatial modeling to construct an image by explicitly computing plane wave arrival angles and amplitudes as a function of range from the sonar, thus enabling the computation of the vertical location of received echoes. During Phase I we will conceptually design an FLS sonar to the unmanned vehicle requirements, use theoretical analysis aided by experiments to validate the concept, identify the performance limitations, and specify a prototype to be developed in Phase II. The anticipated benefits of the Phase I and II development is availability of a prototype sonar practical for use on unmanned vehicle platforms to enhance their ISR mission requirements. The prototype will also serve as a versatile core platform that can be used in a broad variety of other underwater vehicle imaging applications. Potential applications include use on a wide range of commercial and military UUV's and ROV's involved in obstacle avoidance and/or bathymetric mapping/charting.

Title:Advanced Forward Looking Sonar for Unmanned Vehicles
Abstract:The Remote Minehunting System (RMS) AN/WLD-1(V)1 vehicle (RMV) currently does not have a forward-looking sonar (FLS), or any other underwater obstacle avoidance sensor. This means that the RMV itself, while towing a sonar array, will be "flying blind" in littoral environments that are expected to have mines and other obstacles. Operating without an FLS poses a significant risk to the vehicle, and therefore to the RMS mission. The addition of an FLS to the RMV will eliminate this risk. Sonatech is in a unique position to rapidly develop a design for an FLS for the RMS application that incorporates state-of-the-art technology and features and that can be produced with low risk. This is because Sonatech has extensive experience in high-performance FLS design and has previously developed a design concept proposed for the RMV FLS. Using a combination of existing design and technology along with development of new and modified transducer array designs, Sonatech can produce an FLS with the performance capabilities desired for the RMS, compatible with installation on the RMV.

Title:Expendable Array Installation System
Abstract:Rapidly deployable acoustic surveillance in the form of the Littoral Combat Ship (LCS) mission modules will significantly extend the tactical horizon of tactical platforms. This will be accomplished with wireless connectivity to the off-board sensor. The Advanced Deployable System is on the brink of providing this capability but is in need of an expendable installation system for deploying an underwater acoustic array. Progeny is teaming up with Ocean System Inc (OSI) to provide a Wet-end Installation System Element (WISE) and a Low Cost Array Installation Vehicle (LCAIV) to perform this mission. Our phase I effort includes the performance of functional and physical trade-studies to provide a preliminary design of the LCAIV and WISE components. Our team's innovative approach for the WISE is a launch-and-forget "bullet" that includes the array(s), power, processing, buoy and the vehicle. The LCAIV is novel with low-cost horizontal and vertical thrusters and advanced navigational capabilities to ensure that the array is laid straight. Progeny's experience in deployable sensors coupled with OSI's expertise in low cost unmanned underwater vehicles will enable our team to provide a capability to the Navy that will transform the way that ASW is performed in the littorals.

Title:Advanced Pressure-Tolerant UUV Batteries for Fleet Use
Abstract:In the proposed Phase I program, Bluefin will prepare and submit a safety data package for high cycle-life, long shelf-life, advanced pressure tolerant lithium polymer ("Li-poly") batteries for use in, and from the host vehicles of, the AN/BLQ-11 Long Term Mine Reconnaissance System ("An/BLQ-11") through provisional safety approval from NAVSEA's Carderock Division under NAVSEA Technical Manual S9310-AQ-SAF-010 ("S9310"). In addition to the benefits of high-cycle life and long shelf life, pressure tolerant Li-poly batteries would be superior to alternative energy sources for unmanned underwater vehicles because they are robust, safe, do not require failure-prone, heavy pressure housings, and are orientation agnostic. Advanced pressure tolerant batteries are not currently available because of issues with basic battery chemistry, non-standardized manufacturing methods, undiagnosed failure modes, and the absence of lightweight durable packaging. Leveraging U.S. Navy SBIR funding with Bluefin's development efforts, we propose an innovative solution for UUV batteries using commercial Li-poly cells with safe, lightweight packaging and safe "smart battery" electronics.

Title:Multiple Secure Level Simulation Federation Technology
Abstract:To date, a brute-force approach has been taken on handling security within HLA. In particular, a federation typical operates in a "system high" security mode. This approach can be costly and might require security upgrades to some federates, and/or limiting participation by individuals who are not cleared to higher levels. A preferred approach is to enhance the HLA, and supporting infrastructure, so that it can allow operation in a multi-level secure (MLS) mode. The fundamental missing capability is an RTI capable of enforcing mandatory access controls over labeled objects and attributes. This effort will develop such an enhanced MLS RTI and develop a tool for adding security level information to the FED files that define federations within the HLA architecture MK, the leading supplier of a COTS RTI, will leverage their products and expertise to create an MLS RTI and a tool for establishing the security levels and compartments of federation data, to the granularity of individual object attributes. MK will take advantage of current COTS efforts to handle the protection of labeled data - by building the MLS RTI on top of a "trusted computing base" capable of enforcing mandatory access controls, and CCEVS validated network security devices.

Title:Simulation Gateway (SG)
Abstract:Increasingly, national and international organizations are relying on a standards-based simulation infrastructure to interconnect simulation capabilities, to increase simulation interoperability and control modeling and simulation (M&S) costs. The High Level Architecture (HLA) has emerged as the Department of Defense (DoD) and multinational standard of choice for simulation infrastructure The HLA however, does not provide for federations of simulations operating at different security levels. A clear need exists for multi-security-level (MSL), HLA-complaint infrastructure components that will allow for simulations of a federation to operate at different security levels. Trident Systems proposes to develop a MSL simulation capability based on Trident's MSL Collaboration Gateway and the NSA-certified ISSE Guard. We will develop the Simulation Gateway (SG) architecture to support multi-security level simulation federations of combat systems. In developing the SG architecture, we will rely on our experience and expertise and build upon our current efforts in which we are developing a MSL text chat capability. We will also leverage our research into HLA configuration management of simulations using Trident InterchangeSE to address interoperability issues between multi-national federations.

Abstract:A method of determining electromagnetic susceptibility thresholds for chaotic and non-chaotic field environments is proposed. Field sets and coupled current sets are decomposed into non-chaotic and chaotic components via projection onto deterministic models of the coupled structures. Rather than assume field distributions a priori, ensembles of field data are generated from which statistical properties (when present) can be inferred.

Title:Electro Magnetic Probability of Effect (EMPE)
Abstract:The Navy is required to demonstrate the immunity of its ordnance and electronic systems to electromagnetic threats. Simple pass/fail testing is no longer adequate for demonstrating compliance in a field environment increasingly characterized by high power transmission. The Electro-Magnetic Probability of Effect (EMPE) tools proposed in this SBIR will enable the Navy to design new systems and assess their electro-magnetic vulnerability based on statistical characterization. EMPE offers the ability to quantify system hardness, margin of safety, and to extrapolate likelihood of failure under severe electromagnetic exposure without resorting to simplistic, expensive, and hazardous tests. The intent of this SBIR is to support the development of a methodology for assessing the probability of effect (PE) or failure of subsystems/components when used in a variety of systems at different EM stress levels. This methodology removes the requirement for testing using exact simulations of the specified EME. In addition, it provides procedures for addressing the impact of system configuration and EME changes. The methodology is comprised of two elements, which when combined provide a prescription for estimating the PE of the subsystem/components located in a system when subjected to a specified EM level.

Title:High Power Phase Shifters
Abstract:Recent advent, and significant progress made in the wide-band-gap semiconductor technology offer today a promise for a superior high power phase shifter. More specifically, emerging Gallium Nitrate (GaN) HEMT devices are shown to operate in extreme temperatures (~600C), exhibiting high breakdown voltages (~100V) and high current densities (~1.5A/mm). In order to meet these challenging technical requirements in a cost effective manner, F&H proposes to develop a GaN HEMT based MMIC high power phase shifter. During the Phase I of this program GaN HEMT device switch characteristics will be measured and modeled. Models derived will be synthesized with appropriate phase shift elements, and overall performance will be optimized in S-Band. The results will be empirically verified using discrete GaN HEMT devices in lumped element phase shifter circuits. Ultimately, the feasibility of a GaN HEMT based high power phase shifter will be determined. In addition to meeting Navy requirements for shipboard radar, cost effective MMIC high power phase shifters will enable migration of many fixed antennae to beam steered versions to include LMDS, cellular (3G & 4G) and satellite applications. Vast markets associated with these applications will naturally lead to economy of scale pricing, in line with Navy objectives.

Title:High Power Phase Shifters
Abstract:This proposal addresses SBIR solicitation number N04-057 entitled "High Power Phase Shifters". The phase shifter is a critical component that enables array antennas to provide beam shaping, pointing and nulling. This SBIR calls for the investigation of the use of new wideband gap semiconductor materials to replace current ferrite phase shifter technology. Important performance characteristics to consider include power handling, insertion loss, switching speed, operating frequency (S-band), bandwidth and cost. Hittite proposes both innovative technology and circuit techniques to address the SBIR goals. Currently the dominant high power solid-state control component technologies include Silicon and AlGaAs PIN devices. Supported by new government programs wideband gap technologies such as SiC and GaN are experiencing rapid development for application to microwave power amplification. These developments will ultimately result in GaN and SiC, FET and PIN devices suitable for high power control applications. Herein we present some early results of a SiC PIN device under development at Cree. Phase I activity will include continued surveying of progress in the wideband gap area and characterizing devices that become available. A variety of analog and digital phase shifter topologies will be investigated and a trade study of MMIC versus hybrid implementation will be carried out.

Title:Flywheel ACS for long Range Projectiles
Abstract:The Navy has identified a need for a very compact and rugged attitude control system to maintain "nose first" attitude for projectiles that travel outside the atmosphere. This solicitation specifically addresses an attitude control system design sized to provide torque sufficient to rotate a 100 kg projectile with an angular moment of inertia of 4.42 kg m^2, 90 degrees on its pitch axis in 270 seconds and then reduce the pitch rate to the needed reentry rate to a tolerance of 0.3 degrees/second and achieve a zero-degree reentry angle of attack within 3 degrees. The system design must be suitable for gun launch at 12,000 G,s. Quoin has developed a highly effective means of providing attitude control torques with flywheels. We can provide continuous pitch and yaw torque in a spinning vehicle in a very small package. This innovation can be used in future Navy gun and electro magnetic (EM) launched projectiles and in exo-atmospheric missiles. Quoin will demonstrate functionality of Flywheel ACS through analysis and simulation using 3-DOF Simulink models. The simulations will be validated through hardware testing. Perform ACS design studies. We will build and test a single-axis integrating module to demonstrate high torque Flywheel ACS concepts.

Title:Automated Situational Awareness Technology for Collision Avoidance
Abstract:The primary sensor used by a submerged submarine for target detection, tracking and collision avoidance is passive SONAR. Modern SONARS have evolved to a point where contacts can be detected and tracked with a high degree of accuracy. There are situations however, when contacts are not detected or trackers become unstable due to acoustic conditions or relative position of the contact to the submarine. This can result in a close encounter or even more disastrous, a collision. All vessels emanate horizontal electric dipole (HED) and extremely low frequency electromagnetic signals (ELFE) caused by permanent galvanic corrosion currents on the hull of the vessel, which leak into the surrounding conducting seawater. These signals have been detected at ranges to 2000 meters. E-field sensors have specific advantages over acoustic sensors because they are not affected by acoustic conditions and are most effective inside SONAR near field ranges. An array of E-Field sensors on the submarine hull can provide enhanced short-range localization. Acoustic and E-Field signal detections can be fused to provide an alert to the submarine Commander of contacts "close aboard" therefore improving situational awareness and avoid disastrous consequences such as a collision at sea.

Title:In-Harbor/At-Sea Ship Defense with Terahertz Sensors
Abstract:Providing defense to ships against asymmetric threats under all weather and traffic conditions requires both broad spectrum sensing and highly mobile platforms. We propose broad spectral sensing with co-located visible, infrared (IR) and terahertz (THz) sensors that are small, light and low-power enough to be mounted on a unmanned aerial vehicle (UAV). This approach takes advantage of the considerable effort the Navy has already invested in UAVs, and combines it with the high promise of co-located broadband sensor systems. By enabling ultralight low-power sensors that fuse images from three spectral regimes, we offer a new broadly applicable approach to counteracting asymmetric threats.

Abstract:Submarine commanders are currently hamstrung in tactical mission planning due to the limited capability to assess operational options in response to changes in the threat, environment or assigned objectives. Current techniques to evaluate the assigned mission take little advantage of the recent leap in decision support and visualization technology and rely greatly on the manual methodology used during the Cold War. In response to SBIR N04-066, 21st Century Systems, Inc. is pleased to propose researching and developing the Submarine Tactical Planner (SubTaP), an advanced decision support system that will enable the operator to project his ship into the mission area and run sophisticated scenarios over the entire range of expected and unexpected conditions. This tool will have intelligent agent software that can be readily assigned to perform optimization calculations to guide the commander in determining how best to employ his ship in response to a variety of "what if?" situations. The results of this agent-based planning process will be presented to the operator on a 2D/3D display that will clearly allow for visualization of uncertainty as well as the best, average, and worst case over the range of assumptions.

Title:Uniform Abstract Syntax
Abstract:The differences between the abstract syntax (as opposed to the concrete syntax) of programming languages are mostly issues of binding. Architecture Technology Corporation proposes an abstract syntax representation that represents binding explicitly and uniformly for programming languages. The syntax can express differences in variables, scopes, and parameter passing. It can express differences in object systems and module systems. It can express generics and type systems. The abstract syntax has a simple but very expressive semantics based on a typed functional/object calculus. It employs higher-order abstract syntax (as found in lambda-Prolog) to represent binding sites uniformly; and uses explicit staging (as found in MetaML) to represent binding times uniformly. The abstract syntax has an external representation as valid XML documents. The design of transformation and unparsing tools to handle higher-order, multi-stage syntax is considered.

Title:Analytical tool sets with models, metrics, and measurement techniques for System Architecture development.
Abstract:The Department of Defense (DoD) and the commercial sector have become increasingly affordability conscious. In this environment, system architectures have a significant role in developing and maintaining functional performance, affordability and supportability over the life cycle. This SBIR project develops an architecture evaluation framework for analyzing complex, dynamically reconfigurable, net-centric system architectures such as DD(X) to ensure effective system operation and maintenance. ASSETT has previous experience in both DoD and commercial industry in the development of architecture evaluation tools and is partnered with Stevens Institute of Technology to tailor a framework consistent with DoD and commercial industry requirements for this SBIR. Our approach uses systems engineering processes to focus on nine (9) key attributes: deployed operations, functional performance, physical implementation, RMA, expandability, customer?s and developer?s organizational structures, technology, security, and cost. Phase I of this effort produces a lexicon and metrics that allow system architects to assess complex, distributed systems. Our approach establishes a framework that compares the viability of candidate architectures and provides a set of test cases to demonstrate the effectiveness of this architecture evaluation framework. Phase II incorporates guidance from the Navy and focuses on developing and demonstrating the prototype assessment framework via the test cases.

Title:NVision-TM: An Environment for the Analysis and Simulation of Complex Architectures
Abstract:We propose to investigate and design an interactive and practical environment called NVision for modeling, simulation, dynamic reconfiguration, evaluation and visualization of software and system architectures for performance and reliability. NVision will be capable of modeling, simulating, documenting and visualizing the behavior of distributed dynamic systems. NVision will provide interfaces to popular tracing tools for commonly used platforms in order to collect, analyze and import performance data. This will be used to construct software performance models using a popularly used framework and populate model data. In addition to a variety of performance-metric collection and reporting, the simulation engine will support interactive time-based debugging and system inspection, to facilitate insight into the operation of complex protocols and behavior. Standard and programmable plug-in modules will aggregate and propagate key reliability and performance parameters through hierarchy elements for easy visualization and navigation. The standard model can be augmented using a powerful plug-in framework allowing custom definition of (a) components using visual catalogs, (b) component properties using customizable property sheets, and (c) component behavior using an application programming interface in terms of resource-centric operations. NVision will provide a user-friendly environment for independent, hierarchical design, and interactive binding of hardware and software aspects of the system, aiding performance-sizing design decisions. NVision will also offer standard and customizable visualization of results using charts and reports.

Abstract:The development and maintenance of large distributed software systems remains a difficult problem. We propose a targeted effort that will improve system management (such as version control / configuration management) while providing system analysis via task scheduling in a self-consistent manner. Although the approach is high-level in that it is targeted at the ability to handle thousands of software elements deployed onto hundreds of hardware platforms with a generalized inter-network connecting them, it will also be capable of incorporating realistic effects of process activation and communication overhead, resource contention, and other effects in large-scale systems design. The utility will be delivered in the form of net- and web-based tools using a multi-tier web service approach.

Title:Compact Variable Depth Sonar (CVDS)
Abstract:The current tested and proven LBVDS system is limited in the platforms that can host it due to the large volume and weight requirements of the system. Active Signal Technologies proposes to retain the high power density features of the system, but modify it to retain as much performance as feasible in a much smaller package. To achieve this, we will perform a rigorous study of materials, transducers, arrays and deployment systems based on both modeling and the build/test experience we have with several types of each component. At the conclusion of the study, we will generate a design for a system that will exceed 200 dB SL in the 1-7 kHz band, retain directivity, be rapidly deployable, and be small enough in size to be installed on a wide variety of platforms, including unmanned vehicles. The Phase I program will concentrate on the down select of components, and the Option Phase will develop a system design based on the results of Phase I in preparation for prototype system development in Phase II.

Title:Compact Variable Depth Sonar (CVDS)
Abstract:Recent sea tests with a Variable Depth Source (VDS) (e.g. IUSW-21, LBVDS) have demonstrated increased submarine detection capabilities with a broadband active source that provide continuous active acoustic coverage below the layer and along the entire water column. The primary disadvantage of a VDS is the high impact that its launch and recovery system has on ship design. Advanced Acoustic Concepts (AAC) intends to investigate and evaluated key risk areas including automated launch and recovery and tow body design that leads to a small volume, lightweight system deployable from a small onboard handling system. The system proposed will address source levels greater than 200dB//1 uPa at 1 meter and will span a frequency range of 1-7 kHz. AAC's design will be modular, able to fit inside a 30 foot ISO container (30 x 8 x 8.5 feet) to allow for installation on a variety of smaller future vessels and possibly unmanned vehicles. It will also be able to search the water column rapidly, therefore deployment and retrieval speeds will be a consideration. Advanced Acoustic Concepts (AAC) intends to develop a conceptual design of a compact active variable-depth broadband source and perform static acoustic performance modeling for source level, transmit beam coverage, and transmit energy requirements. AAC also intends to define a concept for the associated handling gear.

Title:Dual-Mode Broadband Surface Ship, Hull Mounted, Mine Avoidance Sonar
Abstract:Alaska Native Technologies, LLC (ANT) proposes to develop a hull-mounted sonar system that would be integrated into the DD(X) HF Mine Avoidance Bow Sonar processing chain to provide search and identification of small objects in the water column 60 swaths in front of the vessel. The proposed approach will develop a dual-mode broadband sonar system, capable of operating in either wide-beam or narrow parametric-beam mode. The wide-beam mode will be used for searching. Once detected, the wide-beam mode and parametric mode are used in combination to localize the object of interest. Once localized, the object is tracked in the parametric mode while being interrogated with focused broadband acoustic energy that excites resonances within the object and provides reliable classification. The proposed sonar will be capable of detecting and identifying an underwater object within a minute at ranges up to five kilometers. ANT has previously demonstrated that multiple pings on an object can produce a 10% increase in PCC with a corresponding order of magnitude reduction in PFA. This performance will be validated during Phase I using Probability of Correct Classification (PCC), Probability of Detection (PD) and Probability of False Alarm (PFA) as measures of effectiveness.

Title:Surface Ship, Hull Mounted, Mine Avoidance Sonar
Abstract:Reducing reverberation noise, and increasing resolution drive the ability to detect, and classify underwater mines in a shallow littoral environment. This proposal addresses the problem with an analysis of reverberation noise from recorded sea tests, adaptive beamforming (ABF), and adaptive direction of arrival estimation (ADOA). In the reverberation noise analysis phase, the primary focus will be on the stationarity of the statistics of the noise to determine how quickly the noise statistics change. This will lead to an ABF algorithm requirement that the chosen algorithm adapt as quickly as warranted by the reverberation analysis. Several reduced rank solutions will be tested to determine convergence and array gain. To further improve resolution, several ADOA algorithms will be tested on the real and simulated data. This will lead to high resolution image that can be tested for detection of mine-like features. All this will be performed in software. Timing, and sizing requirements for major software components will be generated in a COTS platform to determine software, and hardware requirements. In the option phase of the proposal, the chosen algorithms will be upgraded to a real time platform.

Title:Enhancing the performance of HF Mine Avoidance Sonar systems
Abstract:Mines pose a significant threat to the US Navy operations. The success in detecting and avoiding mines and mine like objects in the coastal waters all around the world will be crucial for the various US Navy missions in this century. The shallow water environment requires a robust detection system that is capable of detecting various moored and buried mines at a distance against a reverberation limited background while maintaining a high rate of accuracy and low rate of false alarms. Since the sensors ultimately limit the performance of a detection system, in this proposal we are proposing improvement of the existing surface ship mounted sensors used for mine detection and avoidance. It has been shown that broadband sensors will be more suitable for mine detection. Investigations will be made on the usability of different sensor designs and simulations will be conducted to characterize the improvements quantitatively. Materials to be used for sensor domes will be investigated experimentally during the option period. By fusing the analytical results of Phase-I and the experimental data collected during the option period, a detailed array design for the improved in-stride mine avoidance sonar will be done in Phase-II along with prototype development and testing.

Title:Feature selection, adaptive detection/classification, and beam forming for mine avoidance sonar
Abstract:New techniques are proposed for clutter and multipath suppression, reliable adaptive detection/classification, and beam forming. Generalized (multivariate) prediction-subtraction is proposed for clutter reduction. Innovative blind deconvolution algorithms are proposed for multipath suppression. Adaptive maximum likelihood beam forming, beam deconvolution, and parametric sonar are considered for effective beam narrowing. Proposed detection/classification algorithms use "feature-grams," a generalization of time-frequency distributions that includes many range-varying parameter representations, such as incomplete synthetic aperture feature images from forward-looking echo data. A novel, totally automatic method discovers the best features for a reduced-dimensional feature space from observations of design set feature-grams. The resulting feature space data representation is more meaningful to a sonar operator than the usual principal component representation. New feature-grams and associated classification algorithms are demonstrated via single-echo classification of wideband, wide-beam sonar data from targets in clutter. Segmented feature-grams are proposed for extended hidden Markov models that adaptively classify single-echo or multi-echo data. An adaptive classifier learns to improve its performance using unlabeled echoes from mine-like objects and clutter that are not included in the original design set. Reliable adaptive feature extraction and classification are needed for real-world operation against environments and objects that cannot all be included in an initial design set.

Title:Lightweight Composite Shaft Sealing Mechanism
Abstract:Experience has shown that the failure of drive shaft seals at a bulkhead pass through can occur as a result of collision or combat damage. The resulting flooding can quickly threaten ship survivability. KCI, working with Bath Iron Works and Greene Tweed, proposes to design and build a simple, low cost bulkhead shaft seal for damage control use to quickly seal such leaks. The concept proposed is to use a two part thermoplastic seal/bearing that can be easily installed on the shaft. The inner portion rotates with the shaft. The outer portion is connected to the bulkhead and supported by a tailored composite skirt that attaches to a permanently mounted bulkhead clamp. In Phase I KCI will work directly with BIW and Greene Tweed to conceive and iterate various system alternatives, compare them with our baseline system, and discuss the best of the alternative with the Navy. We will also develop test methods, fabricate test specimens and perform experimental studies to determine the effectiveness of our proposed shaft sealing system.

Title:Smart Hydrogel Shaft Sealing System
Abstract:Mid proposes to use its knowledge of hydrogels to develop a bulkhead shaft sealing device. The proposed system will incorporate hydrogel polymer embedded in an open cell foam. This polymer will be in a powder form until in the presence of seawater (i.e. in the case of a damaged bulkhead shaft seal). The influx of seawater will cause the hydrogels to become superabsorbent, and they will swell to many times their volume, blocking the flow of seawater by the damaged seal.The system is designed to allow a small margin of clearance between the foam and the shaft before it is activated, so the hydrogel sealing system can be pre-positioned before a leak occurs. When the foam-hydrogel composition swells, contact forces against the shaft will be small, and the foam material that will contact the shaft is designed to be low-friction, enabling continued use of the shaft even when seals are damaged. The hydogels will be designed to be selective, so only seawater will activate it. Other fluids the system might come in contact with (hydraulic oil, etc.) will not cause a false activation of the superabsorbency of the hydrogel.

Title:MANET Optimized to Control Power Emissions
Abstract:In this effort we will overcome emissions security and placement issues with current generation wireless networks by implementing adaptive power management into MANET (Mobile Ad hoc Networks) tailored to the Navy's application. Cross-layer protocol optimization in Mantes based on 802.11 x offer the possibility of high bandwidth, low cost partitioned area coverage (i.e. non-line of sight operation through bulkhead partitioned areas), and enhanced digital and signal security. For this effort we will specifically identify and evaluate cross-layer optimization methods that incorporate a distributed model of the effect of power levels on EMCON considerations (as well as the more conventional models that relate power level to transmission error rates and station-to-station message collision for nodes within a shared communications zone). Thus, this network protocol will dynamically set transmitted power levels to meet both EMCOM requirements and network error rate/collision detect minimizing requirements simultaneously. Because most 802.11x transceivers support dynamic power and channel management, this will be possible using COTS network components and open, standards-driven methods.

Title:Wireless LAN Emissions Attenuation Technologies
Abstract:As stated, solicitation N04-076 is requesting a system that violates basic physics. A propagating RF wave attenuates at a rate defined by Maxwell's Equations and without a physical barrier, no additional attenuation can be obtained. Our solution approaches the final goal - how to implement reliable and flexible RF communication throughout a ship without violating EMCON requirements. We do this with a synergistic combination of two technologies, both of which we have been working on for many years. These two innovations are Time Modulated Ultra-wideband (TM-UWB) radio and ad hoc mobile networks. The TM-UWB chip set and operational TM-UWB radios using this chip set are available off the shelf and the software is fully TCP-IPV4 compatible. The ad hoc mobile network technology is also available now, and has already been ported to a commercially available hand held PDA. Together this means that the total system can be tested on a ship during Phase 1. Such a test would demonstrate that robust ship wide communication can be achieved, yet the signals outside the ship meet EMCON requirements. The proposal is very explicit in proving that the required 64 dBs attenuation will be achieved.

Title:Wireless LAN Emissions Attenuation Technologies
Abstract:The Navy desires to use a large number of wireless communications devices on ships with the constraint that communication is assured on board while meeting EMCON conditions. Since EMCON is specified in terms of spatial power density at 1 nautical mile, the emissions of the wireless devices must be attenuated at range. The solution is to employ a methodology of Access Point (AP) deployment which assures communications, defines the RF coverage area precisely where it is needed, and minimizes EIRP on the horizon. A methodology for design and mounting of AP and client antennas permits the transmit power from each to be radically reduced. Shaped beam and multi-beam smart antennas can improve the communication channel where desired, while minimizing power emissions off-board. Polar and spatial antenna diversity can be exploited to provide diversity gain, which improves the communication channel without increasing EIRP. Finally, a power and channel plan is proposed which permits low power, communications assured, non-interfering cells to be used. Oberon proposes to investigate use and applicability of its' integrated shaped and multi-beam antennas, client antennas, antenna diversity technology, and power and channel plans for achieving the desired goal of information assurance on board, while minimizing total RF emissions.

Title:UAV based Network-Centric Communications for Sensors
Abstract:Argon Engineering Associates and Advanced Radio Corporation (ARC) propose a Ku-Band data relay architecture that supports network-centric operations from an Unmanned Aerial Vehicle (UAV). The architecture is comprised of multiple directional, asymmetric links that use efficient Ku-Band up/down converters and exciters, and flexible Field Programmable Gate Arrays (FPGA) operating at baseband to allow different digital modes of signal multiplexing and demultiplexing, with remodulation using any of a set of waveforms, including those that provide Anti-Jam protection. The proposed architecture is intended for Class II and related small UAVs, including the Navy's Vertical Take-Off and Landing (VTOL). Thus, the SBIR focuses on reducing overall system size, weight, and power (SWAP), but maintaining multi-node quality of service from at least 3 Ku-Band remote sensor 10.7 Mbps data links and complementary 200 kbps command and control links. By significantly increasing RF up and down frequency conversion performance and providing the flexibility of digitally combining independent signals, Argon and ARC will provide a unique, multi-band UAV Ku-Band and UHF communications relay system that matches Navy ForceNet objectives.

A specific application would be for the planned Littoral Combat Ship (LCS) missions, although the developed architecture will have broader applications for any surface combatant requiring an Over-the-Horizon (OTH) data link to distributed sensors. A conceptual design for the IP network radio System will be developed, and an optional early demonstration (Phase 1) is proposed as a bridge to more extensive development, testing and demonstration in Phase 2. A successful Phase 1 program will produce a conceptual design for a Navy tactical communications system utilizing a UAV relay that is consistent with FORCENet. A successful Phase 2 program will demonstrate the capability in an ocean environment, using a UAV relay, surface ship and ocean sensors. The results will be significant, and the developed system could be a cornerstone of the future littoral combat communications architecture.

Title:An Integrated Control and Diagnostic System for Marine Diesel Engines
Abstract:A primary obstacle that must be overcome in order for unmanned surface vehicles (USVs) to be able to provide valuable service to the fleet is the need for maintenance personnel onboard the vessel. Failure of a single key component that could easily be replaced or repaired on a manned vessel could cause an USV to have to abort its mission or, perhaps, require a manned vessel to put itself and its crew at risk to retrieve or repair the USV. It is therefore desirable to develop an enhanced automated control system for diesel engines that can perform diagnostics and self-maintenance. Barron Associates, Inc. (BAI) and its subcontractor, Southwest Research Institute (SwRI), propose to develop such an automated system by leveraging BAI's generic diagnostic algorithms and SwRI's marine diesel engine control systems expertise and research facilities. To provide a marine diesel engine system that meets the requirements of this SBIR program, development tasks may be partitioned into three categories: (1) design a diesel engine configuration and control system for high fuel efficiency and durability; (2) incorporate a diagnostic system that can detect and isolate faults and take appropriate action; and (3) extend all scheduled maintenance intervals to at least 1,000 hours.

Title:Control/Diagnostic/Maintenance System for High Speed, High Output Diesel Engines
Abstract:Unmanned surface vehicles have unique requirements for operating reliably during missions of very long time periods without human maintenance. The US Navy has undertaken a R&D initiative to develop and deploy diesel engine powered USVs with advanced technology capabilities. Controls Research, Incorporated in collaboration with Neptune Sciences, Incorporated proposes the development of a novel control, diagnostics and maintenance system for marine diesel engines to support this effort. This control, diagnostic and maintenance system is based on a small but very accurate physics based dynamic model of marine diesel engines. Utilizing this model, synthetic software sensors of the engine speed are formulated, which provide validation checks on the dual hardware engine speed sensors. An extended Kalman filter observer is utilized to filter sensor noise and maintain robust tracking of the engine speed. Diagnostics of engine control functions and engine performance variables are conducted using the engine model to dynamically track and analyze the engine in real time operation. The major benefits of our model based, marine diesel engine control concepts are: 1) Significantly higher reliability and less maintenance requirements than current, state of the art diesel control systems. 2) Flexibility in reconfiguration and adaptability of the control system for use with diesel engines of various sizes and types.

Title:Advanced Control/Diagnostic/Maintenance System for Diesel Engines
Abstract:Impact Technologies, in collaboration with Applied Research Laboratory at Penn State University, propose to develop an Integral Engine Control and Health Management System for Marine Diesel Engines that controls engine operation, monitors engine performance, executes real-time diagnostics and performs engine fault accommodation and self-maintenance functions. Our highly qualified research team will develop an innovative control system design that integrates autonomous health management and adaptive control functions to detect incipient diesel engine faults and provide the ability to reconfigure its control to accommodate for the faults throughout all regimes of engine operation. In addition, once the faults are detected, a self-maintenance component will also be enabled that can extend current practices of periodic maintenance systems already in development in other autonomous vehicle systems. The overall program goal will be accomplished utilizing a hierarchical software architecture that is well suited for adaptive modeling and control, and can simultaneously support real-time embedded code operation. Specifically, through accurate engine regime recognition and the fusion of health management and controls logic, intelligent reasoners will provide automated response analysis to changing environmental and system degradation/failures in real-time. The technologies proposed herein will be developed and tested using data to be acquired from the Diesel Engine Test Bed at the ARL of Penn State.

Abstract:MSI will collaborate with various diesel engine manufacturers to create a Sentient Autonomous Maintainer (SAM) for remote diagnostics, prognostics, and self-maintenance of marine diesel engines for use on Unmanned Surface Vehicles (USVs). This SAM will monitor the engine_s current state, predict the engine_s future state, automatically correct conditions when possible, and report impending or current failures to the remote controller. The SAM will make use of Bayesian based artificial intelligence algorithms to operate as an automated Prognostic Health Management (PHM) system. The PHM system will collect and fuse operations data with performance data and then use Physics of Failure models to 1) estimate the state of sensored and hidden conditions, 2) predict time to transition to future failure states, 3) estimate the degree (probability) of safety and economic risk in the predictions, and 4) provide accurate decision support. PHM has been shown to be valuable in providing advanced warning of conditions that lead to failure of expensive weapon systems so that Condition Based Maintenance can be performed in a timely and effective manner.

Title:High Energy Density Power Sources for Unmanned Surface Vehicle (USV) Sensor Payloads
Abstract:Unmanned Surface Vehicles (USVs) require a low signature power source for on-station operation of sensor payloads. The power source must have a high energy density, be reliable, require low maintenance, and be able to withstand salt spray and heavy seas for a two week mission duration. In addition, the payload duty cycle requires up to 25kW peak loads for ten seconds out of every minute, with constant loads of several kilowatts. For the proposed Phase I effort AeroVironment will investigate the feasibility of using the propulsion diesel engines in hybrid with a lithium battery pack and potentially other power sources. Strategically sizing the battery pack to handle the ten second peak loads and average continuous loads while on station allows the propulsion diesel engines to operate intermittently as an energy storage system charger. Under critical conditions, the battery pack or other power source would be the sole supply of sensor payload power, thus allowing USV silent operation. AeroVironment will overcome project technical challenges using our experience gained developing many hybrid electric vehicle systems. By demonstrating feasibility, we will assist the Navy to develop silent mode, low signature operation of its USV fleet for periods of two weeks.

Title:High Energy Density Power Sources for Unmanned Surface Vehicle (USV) Sensor Payloads
Abstract:Without humans onboard, small unmanned vessels will be capable of remaining on-station for much greater lengths of time than their manned counterparts. This long cycle time puts great demand on the onboard power generation systems, as these systems must be compact and light weight in order to fit into the small mission spaces, yet feature exceptional fuel economy if the vessel is have reasonable time between fuel shuttle visits or return trips to the host vessel for fuel. The result of a fuel-inefficient power generation system would be an increased host ship launching and recovery of fuel shuttles or the craft itself, either of which would hamper the effectiveness of the host ship, which is also attempting to showcase reduced staffing. In this manner, the entire concept of larger LCS-type ship utilizing small USVs relies on a fuel efficient USV power generation system for mission effectiveness. The proposed effort involves researching conventional and unconventional engines, energy storage, and energy conversion devices. Recent advancements will be considered alongside proven technologies in an attempt to evolve an efficient combination that can be utilized to improve the on-station time of USVs, as well as enable high power systems on small manned craft.

Title:Hybridized Magnesium Air Fuel Cell With Ni-Zn Battery or Electrochemical Capacitor as the Ideal Energy Source for USV Sensor Payloads
Abstract:In this SBIR program, a novel hybridized magnesium-air fuel cell and nickel-zinc battery is proposed as the ideal power source for USV sensor payloads. After extensive comparisons between batteries, metal-air fuel cells, and hydrogen fuel cells, it becomes clear that eVionyx's magnesium air fuel cell is the best choice in terms of specific energy, energy density, fuel loss rate, ease of refueling, system cost and overall safety. With the availability of seawater, we found that eVionyx's innovative Magnesium-Air Fuel cell can provide more than 4 times the energy content than the state-of-the-art hydrogen fuel cells. By hybridizing the Mg-Air system (ultra-high energy density) with our Ni-Zn battery (ultra-high power density) or optionally, an electrochemical capacitor, an ideal power source for the Naval USV mission is created that can provide 25 kW pulse power and a duration of more than 14 days. The overall objective for Phase I of this project is to demonstrate that a hybridized Mg-Air fuel cell and Ni-Zn battery (or electrochemical capacitor) is the best choice. In Phase II, a full-scale prototype system will be built and tested according to the USV power profile.

Title:Shipboard Lighting System
Abstract:Future military action may be more covert, which will involve more stealth technology integrated into military hardware. New navy ships are in design with a low profile and sloped sides in order to reflect radar away from hostile receivers. Other ship components will also need to be upgraded. Current light fixtures have geometries that can reflect radar waves back toward hostile receivers. They are also not very efficient and waste much light directed beyond the boundary of the ship. Further, these light systems are not NVD compatible and cause current NVDs to saturate obscuring the users view. Breault Research Organization (BRO) proposes to design a new light system for new navy ships that will maximize light in the illuminate area and minimize the light outside of that area. We will select specific sources to provide sufficient lumens to meet illumination requirements and be NVD compatible. External controls will be design to control optical output power. Our design will be integrated into existing bulkheads in order to take advantage of the ship's reduced RCS. Local source and remote source configurations will be evaluated based on illumination efficiency, coupling efficiency and transmission loss.

Title:Fire-resistant, Spray-on Elastomers for Blast Protection Coatings
Abstract:The development of spray-on, fire-resistant coatings to minimize blast damage and contain fragmentation products from accidental or deliberate shipboard explosions is proposed. The coatings are based on elastomeric polymers containing toughening and fire-retardant additives. In Phase I, several polymer systems will be evaluated with the objective of down-selecting to a coating suitable for scale-up in a Phase II effort. The relative performance of the coatings will be evaluated by ballistic testing (MIL-STD-662F) and by fire retardant and thermal properties measurements using Intermediate Scale Calorimetry (ICAL) ASTM E 1623-01 and ASTM 162-02a flame spread measurements. For these measurements, the coatings will be applied to 3/8" thick DH36 steel plate which is extensively used for internal bulkheads on vessels such as the DDG 51. A Phase I Option for the development of a 100% solids spray-on formulation is also proposed. The Phase II effort would address the refinement of polymer and additive chemistries to optimize blast protection and fire retardant properties, scale-up to large-area coatings, color options and coating repair.

Title:Blast Protection and Damage Mitigation Coatings
Abstract:Large bombs are the weapons of choice for global terrorist networks. Brutal attackers have become dangerously efficient at delivering these explosive devices to their intended targets. Fortification of Navy ships against these deadly explosions would greatly reduce the physical and psychological damage inflicted by these bomb attacks. A unique elastomeric polymer has recently been proven by DoD agencies to mitigate powerful explosions and retain structural fragments that inadvertently become part of the weapon. The material is applied as a lightweight monolithic coating and does not contain volatile organic compounds. Its proliferation for use in Navy ship interior applications has been impeded by its inability to resist fire and by smoke generation during combustion. TRI proposes advancements to the proven polymeric coating by incorporating new chemistries with fire retardant properties. In addition, approved fire retardant additives will be evaluated as synergists to the new polymer system. The new coating will retain the desired blast mitigation properties that have been reported and will meet strict fire resistance standards. TRI will utilize its extensive experience with the coating system and our past successes in the development of fire resistant polymers for demanding DoD applications.

Title:TLS (Thunder and Lightening Shield)
Abstract:Over the last several decades new threats to U.S. Navy ships have emerged, and these threats are difficult to defeat with existing shipboard weapons and countermeasures. Chief among the newer threats are sea skimming cruise missiles and small, fast boats containing explosives. These threats are dangerous because they may get inside of ships' normal defenses, most of which are intended to engage and defeat targets at operationally significant standoff distances. The proposed Thunder & Lightning Shield (TLS) concept is to employ Metal StormT technology as the means of applying concentrated firepower to the threats. Integral to the Metal StormT (Thunder) technology are Foster-Miller's non-lethal (Lightning) payload options against drivers and boats. Incorporating Foster-Miller, Inc StingrayT incapacitation net technology within portions of Metal StormT pods, or as separate non-lethal weapons similar to FMI's BoatTrapT designed as a mortar launched asset. The Metal StormT concept utilizes multiple barrels in aiming "pods" with multiple projectiles per barrel, and electronic firing with no moving parts to achieve extremely high rates of fire over short periods of time. The precision of this firepower can be achieved by proper integration of the Metal StormT aiming pods with shipboard target acquisition and tracking systems. (P-040295)

Title:A Plasma Point Defense
Abstract:Research Support Instruments, Inc. (RSI) proposes to develop an innovative defense technology: a large volume plasma generator configured into a plasma point defense cannon to intercept incoming kinetic threats. RSI has developed a patented device to produce large volume atmospheric pressure plasmas. The design is simple, inexpensive, and reliable, using technology found in commercial and industrial microwave heaters. RSI will modify its existing microwave air plasma generator to produce plasma projectiles that will strike targets with high temperature, ionized air. RSI will optimize the technology for effectiveness and efficiency as a plasma projectile and use its expertise in nonintrusive plasma diagnostics to fully characterize the plasmas. The atmospheric pressure discharge will travel to the region of highest microwave field intensity, thus striking the target that has been tracked by a microwave transmitter array. Phase I will include construction of a transmitter station pair, characterization of the plasmas, and a demonstration of plasma generation. Phase II will involve the construction and test of a phased point defense array.

Title:Passive Dynamic Icephobic Coatings
Abstract:The proposed research investigates the feasibility of developing an innovative icephobic coating that will prevent ice accretion on metallic and composite surfaces via the phenomenon of passive dynamics. The feasibility studies involve designing a surface that stresses the ice-surface interface as the ice forms. A material will be incorporated in the coating formulation which will exist in a passive or dormant state under most environmental conditions, but upon the imposition of ice-forming conditions the material becomes "active". This dynamic action is expected to form a truly icephobic coating. The success of the research program will result in a significant step forward in the state of the art of suppressing ice accretion upon a variety of different surfaces where ice buildup can cause serious problems.

Abstract:The primary means of de-icing steel or aluminum structures on ships today consists of physical removal of the ice by impact with sledgehammers and aluminum baseball bats. Due to the introduction of composite structures on Naval vessals, deicing methods are required that do not result in impact damage to the composite materials. In response to the need for a more advanced de-icing system for shipboard composite structures, the development of a "naturally" heated deicing fluid and a mechanized, lightweight and portable preparation and application device is proposed.

Title:Icephobic Coatings to Reduce Ice Accretion on Composite Structures
Abstract:The accretion of ice in arctic environments is an expensive problem for the power transmission and microwave industries; the military, whether on land, sea, or in the air; and airlines that operate in blizzard-like conditions. Traditional de-icing relies on physically breaking the ice or using chemicals to melt the accreted ice, which are only temporary solutions. Some coatings have been explored that attempt to prevent the formation of ice on a surface, but many of these are also temporary. TPL proposes a durable coating that will significantly delay the formation of ice on a variety of surfaces. The coating is a molecular combination of organic and inorganic constituents specifically designed to be durable and icephobic. The inorganic component will impart hardness and durability, while the organic part will impart flexibility and icephobicity. The wet-chemically derived coating is easy to apply and has excellent adhesion. Proposed coatings will be evaluated for icephobicity by the Army's Cold Region Research and Engineering Laboratory, which is well-known for their abilities in icing research. Mechanical properties will be tested by TPL, whose investigators have extensive experience and resources in wet-chemically derived coating technology.

Title:Lightweight Passive Fire Protection System for Composite Structures
Abstract:MicroPhase Coatings submits this proposal under SBIR Topic N04-085, Lightweight Passive Fire Protection System for Composite Structures. Our solution builds on an innovative, patent-pending Thermal Barrier Coating (TBC) which is under development for non-rotating jet engine parts. TBC is a largely inorganic coating that converts to completely inorganic ceramic after exposure to 900oF. We conduct trade-off analyses, modify the coating with various fillers including nano-clays, and make other adjustments to meet Navy requirements of fire resistance; limiting fire growth; environmental tenability; adhesion in the presence of shock, vibration, and salt fog; durability and maintainability; manufacturability; and affordability. We team with Southwest Research Institute, world leaders in fire testing, to complete Phase I ASTM-E-1354, ASTM-E-162, and small scale fire resistance tests, precursor to full scale UL-1709 tests which we will conduct during Phase II. We team with Goodrich Engineered Polymer Products, providers of composite materials and components for US Navy ship construction. During Phase I we establish a relationship with a shipyard, working through EPP, so that by the end of Phase II, we have a product qualified for use and a plan for integrating the product into ship construction.

Title:Lightweight Passive Fire Protection System for Composite Structures
Abstract:Mississippi Polymer Technologies (MPT) proposes to protect composite ship structures with novel, lightweight flame resistant insulation composed foamed Parmaxr Self-Reinforced Polymers ("SRPs") compounded with carbon fibers. Parmaxr SRPs are extraordinary thermoplastic polymers that do not melt or drip at high temperatures but form a durable, insulative char layer. Parmaxr SRPs have the potential to meet and/or exceed all of the US Navy's surface ship fire safety goals. These impressive polymers do not burn, and the proposed foamed insulation is an ideal choice for limiting fire spread and minimizing fire growth. Additionally, the viability of the surrounding area will be maintained because Parmaxr SRPs are inherently non-toxic and non-fuming when exposed to heat. Application of the proposed fire protection insulation can be easily accomplished by thermoforming the foam to the desired shape then attaching it to the substrate by adhesive or mechanical means.

Title:ENCAPT Passive Fire Protection System for Composite Structures
Abstract:New ship construction will rely more heavily on composite structures, which provide structural strength with light weight, but with increased vulnerability to fire damage. To prevent catastrophic fire damage, Softronics is offering ENCAPT as a lining material for the composite structures to passively protect it from fire damage. ENCAPT was developed and patented by Dr. Benjamin Mosier, Institute for Research, Inc., and Mr. Robert Sternowski, Softronics Ltd., for use as a fireproof insulation panel, and has undergone significant testing in preparation for entering that market. This unique plastic composite material combines a filler with a hybrid phenolic resin to produce a moldable material that has all the key properties for naval use: light weight, Class 1 fireproof (Class 0 with cladding layer), non-flammable, non-toxic, non-corrosive, non-absorbent, and structurally rigid. The material is easily manufactured with a small capital investment, and thus is ideally suited to limited production runs for a small number of trial ship installations.

Title:Lightweight Passive Fire Protection System for Composite Structures
Abstract:Sordal proposes to design a lightweight passive fire protection system that is 200% lighter than current fiberglass or mineral wool products used by US Navy, thermally stable to more than 600F (316C), non-flammable, and non-combustible. It will have an exceptionally high limiting oxygen index (LOI=68%) and will be nontoxic in a fire, yet very strong. This material is designed to pass UL-1709 and ISO-9705 based on previous testing in related standards such as the room scale fire test per Navy Chapter 635 requirement, as well as testing completed by NASA where Sordal's material is a candidate insulation for the next generation space shuttle. Sordal's lightweight insulation can be fabricated as: - Neat foam, open cell (flexible), closed cell (rigid) or combination thereof. - Structural foam barriers (foam-filled honeycomb core or sandwich pins to +1,000 psi loading). - Combined with non-flammable PBO fabric blanket to stop fire spread. - Chalking compound for repairs in-situ (hollow microspheres with proprietary adhesive). Unlike Sordal's proposed system, many commercially available passive fire protective systems fail in an ocean environment due to water regain and retention and cracking during routine thermal cycles. Additionally, Sordal's system doesn't "dust" or release fibers like fiberglass and mineral wools.

Title:Integrated Bridge Sonar Interface and Object Avoidance
Abstract:The objective of this proposal is to demonstrate the feasibility of improving situational awareness and providing automated small object collision avoidance (in-stride mine avoidance) through the integration of real-time sonar data with Electronic Charting and Display Information System - Navy (ECDIS-N). The enhanced ECDIS-N will compute a `safe' route based on mariner-entered parameters, such as cross track error, max and min speed and vessel dynamics, etc. On those ships equipped with Automatic Navigation and Track Keeping Systems (ANTS), the `safe' route can be executed hands-off. For other vessels the route will be followed using traditional helm orders issued by a conning officer. In either case, the ECDIS-N will present the mariner with an integrated picture that graphically identifies the ship's position relative to the known geospatial environment, which will now include sonar identified objects. Integration of sonar data is a natural extension of ECDIS-N. Providing a real-time integrated view of the sub-surface environment ahead of the ship will significantly reduce the human data gathering and analytical aspects of navigation in the littorals, thereby enabling the mariner to focus on higher-level mission objectives. There is also a significant potential to reduce bridge manning levels for some ship evolutions.

Abstract:Daniel H. Wagner Associates, Inc. will develop an Object Avoidance Tactical Decision Aid (OATDA) that processes all available data, dynamically generates a CTP and an object avoidance plan, and displays this information on the ship's navigation system. A key capability provided by OATDA will be the ability to fuse data obtained by off-board systems (e.g., Route Surveys, the AN/WLD-1 Remote Minehunting System (RMS), Long-Term Mine Reconnaissance System (LMRS), dedicated MCM systems, other ship's Kingfisher systems) with ownship data in real-time. In addition, we will utilize the contact data fusion and environmental data fusion algorithms developed in our Commander's Estimate of the Situation Tactical Decision Aid (CESTDA) and Environmental Data Fusion for Mine Countermeasures (EDFMCM) projects for ONR to determine a recommended route for the ship that minimizes ship vulnerability to undetected mines or improvised explosive devices (IEDs). As shown in our Cooperative Organic Mine Defense (COMID) work, the ability to utilize non-ownship data significantly improves the ability of the ship to maneuver around potentially threatening objects and dramatically reduces the number of false alarms. The primary algorithmic techniques that will be utilized in OATDA are non-Gaussian and multiple hypothesis data registration and fusion, non-Gaussian optimization, and Bayesian inferential reasoning.

Title:Configuration Management and Monitoring System for Mission Module Interfaces
Abstract:This SBIR will result in the development of a comprehensive framework for the design and integration of health assessment modules, diagnostic modules, prognostic modules, decision support modules and configuration management modules into ship vehicles and other modular systems. Specifically, WPI proposes an Automated Configuration Management and Monitoring System (ACMMS) of shipboard module interfaces for ship vehicles and other modular systems. Our proposed health monitoring system applies engineering principles toward the diagnosis and correction of system malfunctions. The development of prognostic and health maintenance methodologies coupled with advanced distributed computing technology have facilitated the utilization and implementation of engineering principles and experience into a ship-wide automated maintenance strategy. Our proposed diagnostic and prognostic framework is a system-level health management system that receives inputs from sources such as performance monitoring, built-in tests (BIT), and sensors. The ACMMS will (1) process that data to derive diagnostic and prognostic indications; (2) relate status conditions to the ability to perform specific missions; and (3) relate health and status to required maintenance actions and resources. The proposed ACMMS will be functionally partitioned into discrete scalable, reusable modules consisting of isolated, self-contained functional elements.

Title:Remote Lighting Flood Light with Double Fresnel Light Shaping Luminaire
Abstract:Because of their restricted placement and imperfect design, existing overhead floodlights create uneven illumination across the flight decks of Air Capable Ships (ACS). To address the U.S. Navy need for improved deck light distribution, Physical Optics Corporation (POC) proposes to develop a new Remote Source Lighting Overhead Flood Light (RESLOF) system, in which the luminaire is switchable between visible light and night vision lighting. In the luminaire, the light is coupled from a xenon lamp to a fiber bundle. The fiber bundle delivers light to a luminaire, which has a nonimaging collimator and special Fresnel structures, which tailor the output, evenly illuminating the flight deck. The RESLOF luminaire, because it is transparent at radar wavelengths, has no radar signature, and it does not require periodic maintenance. In Phase I, POC will develop and test a preliminary RESLOF system to demonstrate the feasibility of the RESLOF approach and produce a design for Phase II implementation that will meet Navy light distribution specifications. In Phase II, an engineering prototype will be developed and tested in a realistic ACS deck illumination scenario.

Title:Advanced Lightweight Ramps for LCAC
Abstract:A feasibility study and preliminary design shall be developed for an Advanced Lightweight Ramp (ALR) for LCAC made from composite materials. These materials and construction forms such as sandwich structure have demonstrated proven weight savings in many applications and will not corrode in a marine environment. The Navy is increasingly moving toward shipboard composite structures on new ships like DDX and LCS based on the need for topside weight and signature reduction. The preferred manufacturing process for such marine applications is VARTM based on the ability to mold very large parts with good mechanical properties, consistency and low cost. The ALR design offers several significant benefits, the most important being estimated LCAC weight saving of 1,575 lb or 25 percent of the present aluminum Bow and Stern ramps. The composite design does not corrode in a marine environment, reducing current maintenance downtime and cost. Made as one molded unit via the VARTM process, the ALR design minimizes parts count, assembly labor and total ramp acquisition cost. Under the program detailed Bow and Stern ramp designs shall be developed, supported by analysis. Weight and cost projections shall be prepared, as well a standard repair method to address likely service damage. (P-040181)

Title:Conformable Lightweight Pultruded Toughened Composite LCAC Ramps
Abstract:KaZaK Composites will work with MacGregor Group, a leading fabricator of marine ramps, to develop new, lightweight, damage resistant composite bow and stern ramps for LCAC. In Phase I we will evaluate competing concepts for composite ramps that are stiff in the ship-to-shore direction, support bending loads with minimal deflection, and simultaneously are torsionally compliant in the athwart-ship direction, allowing the ramp to conform to ground irregularities. The redesigned ramps will not impact LCAC operations or require costly hovercraft modifications. Ramp designs will be optimized for pultrusion fabrication to minimize cost. KCI operates 10-foot wide pultrusion equipment, and has been involved with numerous Navy programs demonstrating application of pultruded composites to low cost, low maintenance, high performance ship structures and systems. VARTM technology will be used as appropriate to supplement pultrusion in ramp fabrication. Full scale prototypes of key composite structures will be built and tested during Phase I to verify design assumptions and FEA predictions. Weight, cost and damage resistance will be projected, and a comparison made to the current aluminum ramp configuration. The next generation ramp will reduce weight by up to 25%, eliminate corrosion, be extremely damage resistant, and provide other advanced design and performance features.

Title:Lightweight and Repairable Welded Thermoplastic Construction for LCAC Ramps(1000-425)
Abstract:Triton Systems Inc. will develop a hybrid composite design and manufacturing process for the LCAC bow and stern ramps combining welded glass- and graphite-thermoplastic components with proprietary fire retardants to produce lightweight, corrosion-resistant, rugged, and repairable assemblies. Compared to the existing Aluminum ramps, the Triton thermoplastic structures will provide reduced life cycle costs, increased time between failures, and easy repair ability. The fabrication cost for these new composite ramps ranges from "comparable to" to "considerably less than" the existing ramps, depending upon weight and material tradeoffs. We can provide costs less than welded 5456 Al for glass-reinforced thermoplastics, or weights considerably less than aluminum for graphite-reinforced composites, but the appropriate combination of glass and graphite reinforcement requires tradeoffs against prioritized requirements during Phase I. Triton will evaluate, in concert with NAVSEA and Textron Marine & Land Systems, the appropriate correspondence between dollars and pounds saved from the existing design. Triton will team with both Textron for design support and St. Gobain/Vetrotex for development of balanced hybrid graphite- and glass-reinforced thermoplastic feedstocks. Subscale thermoplastic composite assemblies will be fabricated and tested to validate material and joining concepts and associated costs.

Title:Passively Stable Towed-platform Interface for Launch and Recovery of Surface and Undersea Unmanned Vehicles
Abstract:The Navy has identified the need for the development and demonstration of an interface for the launch and recovery of unmanned surface and undersea vehicles at stern ramps of small-deck ships. The Navy further emphasizes that no safe and accurate method currently exists for the recovery aboard ship of unmanned surface vehicles and unmanned undersea vehicles. To respond to these challenges, International Scientific, through its Ocean Systems Division, proposes the design, development and implementation of a passively stable, towed-platform interface that will fulfill Navy requirements of mechanical simplicity and modularity and will have low acquisition and life-cycle costs. The proposed Phase I Technical Objectives include the selection and hydrodynamic optimization of candidate modular towed platforms, evaluation of computer-aided designs accommodating a wide range of unmanned surface vehicles and unmanned undersea vehicles, and integration of sub-assemblies based on a comprehensive trade-off evaluation. These three objectives will be followed by a Phase I Option Objective involving establishment of an engineering model through a design review incorporating cost/benefit analysis of materials and components. The research team of International Scientific - Ocean Systems Division and Massachusetts Institute of Technology - Ocean Engineering Department has an unique capability to meet the goals of Navy solicitation Topic N04.1-092 by providing in Phase I a design and optimization, and in Phase II the fabrication and performance evaluation of a passively stable, towed-platform interface for launch and recovery of unmanned vehicles from small-deck Navy ships.

Abstract:KaZaK Composites and our program partner MacGregor Group proposes to develop a conformable unmanned vehicle ramp that will employ COTS equipment for low cost mechanical components and significantly reduced program risk, in combination with highly damage resistant composite structure for light weight and corrosion resistance. The innovative ramp storage concept will compact to preserve critical onboard space during ramp stowage. Proper laminate and system design will provide added ramp support during launching and retrieving. The proposed ramp design will insure the safety of personnel, ship and UUVs; minimize ship impact cost; launch and recover unmanned vehicles from 10 to 36 feet in length and 21 inches to 12 feet in width, and provide safe and efficient operation in a variety of sea states. KCI specializes in development of automated manufacturing technology for advanced composite structures, with particular emphasis on pultrusion. We will develop designs using KCI's unique capability to pultrude damage resistant composite structures, a technology developed to reduce impact damage related maintenance for Navy landing craft and carrier stanchions. A system optimized for pultrusion production will reduce the cost of the system components to an absolute minimum, approaching raw material cost, if sufficient quantities of similar items are purchased.

Title:Integrally 3D Woven/3D Braided Composite Joining Elements For Ship Construction
Abstract:GFRP cored panels are common in current shipboard structure design. Robust and practical means of joining these and other composite materials to one another and to any substructure are critical to forming large structures. 3TEX will develop and test joining methods and materials based on 3WEAVETM, and 3BRAIDTM, formation of integral shaped fabric preforms. "Butt" and "T" joints formed by insertion of panel edges into pockets in, "H", "T", and "double T" union elements. Investigation will examine rigid, pre-impregnated, and dry preforms. Use of the dry preforms allows the easiest storage by employing subsequent infusion of the joint preforms with the panels in-place, to bind all elements together. Variants that provide through-joint holes for fastening to sub-structures will also be examined. Further, composite insert and hard points, which exploit the increased through thickness fiber, and thread strengths of "very" thick single ply fabric preforms will also be demonstrated. The strengths of inter-panel, and hard point joints will be gauged against existing methods. The cost, and practicality of these methods and materials will be assessed. It is expected that these methods will prove both more practical, more robust, and lower cost than current methods.

Abstract:Z-axis stitching offers improved performance and greatly increased damage tolerance for composite to composite joints (CTC). Z-axis stitching is employed in aircraft applications using complex, double-sided stitch machinery developed by NASA. This technology is very expensive, but offers increased damage tolerance to airframe structures. The team has identified stitching technology which could offer similar improvements for large, thick marine composites structures at a fraction of the cost of aerospace double-sided stitching. This technology has benefits for large marine structures compared to conventional double-sided stitching. The team proposes to develop and demonstrate this technology for CTC joints of large marine laminates. The team assembled are experts in their respective fields: SCI-resin infusion manufacturing, MSC- composites design, Dr. Ing. Juergen Wittig- z-axis stitching technology. Furthermore, opportunities exist to combine this technology with CNC gantry/robot systems to make in-mold stitching of large compound curvature structures automated.

Title:Reactive Finish Formulation for Improving Interfacial Bonding in Carbon/Vinyl Ester Composites
Abstract:The interface is often a limiting factor in determining the durability of composite materials used in harsh environments. Attaining a well-bonded interface is particularly difficult with low-temperature curing matrix resin systems. A need exists for a carbon fiber adhesion promoting finish that is compatible with vinyl ester chemistry. Prior work using reactive coupling agent chemistries modified to function with vinyl ester moieties cures showed that the modified reactive finishes allow control of interfacial adhesion in these composite systems. The reactive finishes provide superior interface dominated mechanical properties and are compatible with resin infusion processing. Carbon/vinyl ester composites fabricated with the reactive finishes are also expected to exhibit improved environmental durability due to the improved interfacial bonding. The reactive finishes to date have been applied from organic solvents. Before these chemistries can be applied on a large scale by carbon fiber manufacturers, they must be formulated into water-based systems. Once that is accomplished, then the finish must be optimized for compatibility with vinyl ester resins, resin infusion techniques, and weaving processes. These areas and the development of an extensive composite properties database, including durability testing, are proposed to be addressed.

Title:Vinyl Ester Compatible, High Modulus Fiber System for Composite Laminates
Abstract:Because of their improved corrosion resistance, high strength to weight ratios, high modulus to weight ratios, and low specific gravity compared to those of metallic materials, fiber reinforced polymer matrix composites have emerged as a major class of structural material in aerospace, automotive and other industries. The properties of high performance composites, consisting of carbon fiber in a polymer matrix, are known to be highly dependent on the quality of adhesion between the different components. This bond quality is dependent upon interfacial properties between fiber and matrix resin, which can be influenced by several factors such as yarn sizing, matrix resin plasticization, and impact strength additives. In theory, carbon fiber composites should outperform fiberglass and even aramid composites in critical performance parameters. To date, this has not been attained for the carbon reinforcement of standard marine vinyl ester matrix resin systems. One objective of this project is to focus on achieving the predicted mechanical properties by means of novel chemicals and a novel procedure. The other objective of this program is to evaluate the physical and chemical mechanisms currently thought responsible for adhesion in order to improve the performance of carbon vinyl ester composites.

Title:Improved Interface and Mechanical Properties in High Modulus Carbon Fiber Reinforced Vinyl Ester Composite Laminates
Abstract:The objective of this proposal is to develop and demonstrate the feasibility of high modulus carbon fiber reinforced, VARTM processable vinyl ester laminates with an improved fiber / matrix interface that will provide increased modulus and other mechanical properties. The appropriate choice of resin will also provide composite structures with reduced flammability, smoke and toxicity. The goal is to produce a fiber sizing that will be applied in a conventional carbon fiber manufacturing process and improve adhesion between the high modulus reinforcing fiber and the vinyl ester resin when cured in a VARTM process. We propose to achieve this improvement in interfacial bonding by sizing the fiber with a combination of a polymeric film former and a coupling agent. The degree of adhesion between the fibers and the matrix as well as the nature of the fiber / matrix interphase have a major influence on the mechanical properties and the durability of a composite. Significant interfacial adhesion is required to obtain effective stress transfer from the matrix to the load bearing reinforcing fibers. If the interfacial adhesion between carbon fiber and vinyl ester resin could be improved then the full potential of these advanced composites could be realized.

Title:Innovative Fiber Treatment and Sizing Technology for High Performance Vinyl Ester Matrix Composite Materials
Abstract:A major limitation of vinyl ester resins is their performance with carbon fiber reinforcements. Carbon fiber composites can possess much higher specific stiffness and strength than glass fiber composites, but the laminated composite properties depend on a good mechanical interface between the matrix resin and the fiber. VE resins typically do not exhibit good adhesion to the carbon fibers and results in generally poor composite compression properties, interlaminar shear properties, and fatigue performance. To address these limitations of VE/carbon composites an innovative approach to increase the fiber interfacial adhesion and toughen the interphase region between the carbon fiber surface and the VE matrix will result in realization of the high strength, high stiffness, and lighter weight benefits of high modulus carbon fiber composites. In this proposed research effort Performance Polymer Solutions Inc. will develop an optimized VE-carbon fiber composite as a system utilizing: (1) a state-of-the-art VE resin; (2) an innovative carbon fiber surface modification; (3) advanced modeling and analysis techniques to efficiently optimize the desired characteristics of the resin-fiber interface; and (4) perhaps most importantly, teaming with a carbon fiber manufacturer to ensure that required fiber treatments are developed with production-scale considerations and transitioned to industry for immediate commercialization.

Title:High Temperature, High Power Density Electronic Devices
Abstract:This project is to develop a power module based on emerging SiC semiconductor technologies capable of handling high current and voltage. SiC-based power electronics have the potential for reliable operation at higher junction temperature, higher frequency and higher power density than that can be achieved with silicon (Si) transistor technology, which the SiC technology-based overall system can be made smaller and more efficient. SiC has the potential for up to a 5-fold reduction in converter volume if high temperature, high frequency power electronics can be implemented. Currently, however, SiC switches and diodes typically have a current rating less than 20A. To achieve higher power level, it will be necessary to parallel SiC die within a high temperature power module. One key issue is to optimize the packaging of SiC switches and diode to allow multiple SiC die to be paralleled within a power module. This Phase I will demonstrate the feasibility of the development of a SiC power module to support a 60KW inverter for the Advanced Gun System (AGS) program.

Abstract:The use of batteries to power wireless sensors remains a major maintenance impediment to their use in large numbers. To solve these problems the Navy desires innovative methods to scavenge power from broadcast RF signals to power sensors. Under Phase I of this SBIR, AEPTEC's Team will create a development plan for energy scavenging in two usage modes: (1) for ambient environments, a single small power unit capable of supplying energy for an low power wireless sensor such as a Mote or MEMS chip, and (2) for directed energy sources, a power unit capable of deriving larger quantities of energy from units such as a 802.11 Access Point. To do these technologies, (i) AEPTEC will employ methods for optimizing RF energy transmission to the target scavenging device utilizing a Smart Antenna design combined with (ii) methods for RF energy reclamation using receive antenna device and proprietary microelectromagnetic physical structures and related circuitry that boasts up to 96% conversion efficiency. The developed solution will not interfere with RF data transfer between sensors and wireless access points and will be compatible with industry standard wireless protocols such as the IEEE 802.11 family, IEEE 802.15 family (Bluetooth), and emerging IEEE 1451.5 standard. A report will be provided that details the concept, suggested metrics and estimated life-cycle costs

Title:RF Power Scavenging
Abstract:There is a strong desire within the U.S. Navy to instrument ships with distributed wireless sensors. A significant challenge in this endeavor is supplying power to the sensors. A requirement to regularly change batteries reduces the advantage of the wireless sensors. Luna proposes to solve this problem by capturing stray radio frequency energy from shipboard systems to supply power to the sensors. The concept is to capture the stray energy with an advanced antenna design and store the energy in either a battery or a super-capacitor. As part of the project Luna will design a suite of micro-powered sensors designed to be run off the scavenged power, and the distributed network to allow the sensors to communicate with the shipboard system.

Title:Asbestos Stabilization Foam
Abstract:Asbestos insulation material has been used in shipboard environments for many years. While the material is usually safe when left undisturbed, it becomes a major health hazard during removal. The fine, needle like crystals that can be released into the air during handling are inhaled into the deep parts of the lung where they are known to cause cancer. Current removal procedures require a completely sealed area, using vacuum to prevent any particles from escaping. Personnel must wear heavy protective equipment. Annual asbestos remediation and removal cost estimated for the DoD are in the $150-300 million range. Removal of asbestos covered piping can cost up to $150 per liner foot. The US Navy is interested in a less labor intensive, and therefore less costly, removal method for asbestos. Adherent Technologies, Inc. has developed a series of specialty foams that can be applied to this problem. By impregnating the material with a very slow curing foam system, we can achieve two important protective properties: the material is encapsulated, and, due to the foam, stabilized. This will eliminate any danger of operators being exposed to friable asbestos. Application would require only light protective gear.

Title:Bio-Remediation of Hydrocarbons on Inactive Ships
Abstract:The Navy is seeking a means of removing hydrocarbons from inactive ships prior to ship dismantling or sinking as an artificial reef. Traditional means of separation of oil from aqueous solutions are unreliable in processing emulsified oils and organic chemicals. Filtration, chemical flocculation, and ceramic membranes simply transfer the contaminated waste to one mediumto another. Therefore, a biomechanical separator is best suited to mechanically separate the majority of the phase separated oil from water and then treat the remaining waste with a novel biological treatment system designed to consume the remaining hydrocarbons, and convert them to harmless byproducts. The Phase I program will develop a biological/mechanical separator that will be capable of removing free-phase oil and consuming emulsified oil in wash water to concentrations of 5 ppm or lower. This proposed system will be portable and usable in confined shipboard spaces.

Title:Remediation of Hydrocarbons by Ultimately Controllable Microbial Bio-Films
Abstract:A delivery process and system is proposed to be used in the field to make inactive ships essentially petroleum free prior to ship dismantling or sinking in an artificial reef. The proposed delivery system involves the use of electrostatically charged aerosols using a proprietary system developed by Foster-Miller named Electrostatically Charged Aerosol Decontamination (ECAD). The proposed application method will allow safe bio-remediation in virtually any onboard location. It will be portable and usable in enclosed shipboard compartments, able to be operated by a small number of personnel (one is preferred) who have been trained in its operation, but without the need of further specialized knowledge. The Phase I program involves the preparation of freeze-dried hydrocarbon degrading organisms, evaluation of the viability of individual microbial strains upon the deposition of microbial suspensions by ECAD on contaminated surfaces, and optimization of the nutrient feeding/wetting frequency by ECAD and monitoring of the hydrocarbon biodegradation. Phase I will focus on evaluating technical feasibility of the proposed bio-remediation process as well as confirming its reliability and estimating its costs. At the end of the Phase I program the performance goals will be established and key component technological milestones developed. (P-040174)

Title:In Tank Bio-Remediation of Petroleum Hydrocarbons on Inactive Ships
Abstract:This Phase I project will demonstrate that bioremediation methods can be used to biodegrade ship-based petroleum products that remain as residuals in tanks, piping and bilges of ships that are destined for dismantling or sinking to become artificial reefs. The tests that have been designed for this project will demonstrate that bioremediation can achieve the objective of making inactive ships petroleum-free without the use of any chemicals or process products that will require disposal as an oily waste or hazardous material. It will also be shown that the cost of bioremediation per unit volume of petroleum or petroleum-based waste has a high potential of being less than the cost of conventional methods currently in use. An additional benefit to be demonstrated is that this bioremediation process can be effectively carried out by one person and that process monitoring can be conducted using low-cost hand-held instruments. It is expected that the results of this project will lay a technical foundation for development of a standardized procedure that can be routinely used by the Navy. Lynntech, Inc. has a broad base of technical and scientific expertise within the company to carry out this project in conjunction with an experienced maritime industry consultant.

Title:Explosive Cutting Technologies Applied to Ship Dismantling
Abstract:In this proposal, state-of-the-art demolition techniques based on a newly patented method (US 6,530,325 B2) are applied to ship dismantling to decrease the manpower and time necessary to dismantle a naval vessel. This method utilizes the cutting and breaking capabilities of explosives to create openings in plating, thereby allowing the use of large hydraulic shears as a primary means of ship dismantling. The method has been used successfully for the scrapping of floating structures as large as 210 ft long and 35 ft wide. In addition, a suite of more conventional explosive cutting and explosive shearing techniques used in the explosives demolition industry will be evaluated for its utility in ship dismantling. These include the use of shaped charges for cutting steel support structures, and of explosive shearing charges (similar to those used in explosive bolts) for shearing large items such as shafts.

Title:Automated Polychlorinated Biphenyl (PCB) Analyzer for Solid Waste Material using SPME/GC/MS
Abstract:The main goal of this Phase I SBIR proposal is to demonstrate the feasibility of developing an automated method that can be used in the field to identify and quantify polychlorinated biphenyl compounds (PCBs) present in solid materials felt gasket, faying material, paint, electric power cable insulation and many rubber products. Solid Phase Microextraction (SPME) has been shown to be effective in the determination of the concentration of PCBs in liquids. In this modified SPME technique, new stable fibers with nano particles will be developed for efficient and selective absorption of PCBs. Modified fiber holders will be developed to automate the accurate determination of the presence and concentration of PCB's in solid materials. This will be a quick, reliable, cost effective and portable device that can be operated in the field by a single person with minimum training. The sensitivity reached with this technique is 5-700 parts per trillion ( EPA regulation 50 parts per million) in an extraction time of only 50 minutes. The sensitivity, extraction parameters and time for analysis will be improved in this proposal. This proposal will also enable the separation and quantitation of toxic PCB congeners and highly toxic polychlorodibenzofurans (PCDF) and dioxins produced from PCBs. This proposal combines SPME with portable GC and/or GC/MS for automated PCB analysis.

Title:Onboard PCB Detection using a Portable Raman Analyzer
Abstract:Contractors dismantling ships must ensure personnel are not at risk and no regulated material release occurs. The contractor is unlikely to have preexisting knowledge of toxins; therefore continuous materials analysis is part of the dismantling operation. For example, polychlorinated biphenyl (PCB) was used routinely in ship components ranging from gaskets to paints to power cords. Highly regulated by the EPA today, PCB must be identified and quantified. There is no EPA-approved field method for PCB detection; the resulting laboratory analysis is costly and slows down dismantling. We propose to develop a portable PCB analyzer based upon resonance Raman spectroscopy. Raman spectroscopy allows rapid and unique identification of the desired analyte; resonance enhancement allows low ppm detection. By overlapping the laser with a PCB absorption band, PCB can be selectively enhanced over any complex matrix. Using a compact portable UV echelle spectrograph, fiber optic coupling and a compact UV laser, we will develop a portable unit capable of rapid (<120 s) quantitative PCB identification. We will determine detection limits, reproducibility, calibration accuracy, and absence of potential matrix effects. The system will be turnkey, automated and used in military and commercial applications needed to meet EPA PCB regulations.

Title:Portable SERS Spectrometer for PCB Analysis
Abstract:A portable PCB detection and quantification system is proposed based on Surface Enhanced Raman Scattering (SERS). The system comprises a SERS sensor head and fiber optics interfaced to a commercially available PDA or handheld computer. Surface Enhanced Raman Scattering is capable of detecting molecules at the parts per trillion level and is well-suited to meet the 50 ppm threshold for PCB detection. Since every molecule and isomer has a unique Raman spectrum, it will be possible to determine the composition of PCB mixtures with high accuracy. The phase I program will construct a prototype system using off-the-shelf components and custom analysis software to evaluate the ability of a portable fiber optic system to meet the detection needs of Navy salvage operations. Phase II will refine the prototype system of phase I by upgrading the detection and analysis components and construct a field deployable test system.

Title:MW Class Near Infrared Optics
Abstract:Aiming laser weapons accurately is a difficult task that is made even more difficult if the laser windows and other components steer or distort the beam during thermal transients caused by the laser beam or other sources. Athermal components maintain the direction and wavefront quality of beams even in the presence of temperature gradients. Existing athermal materials do not have the high laser damage threshold and very low absorption of laser light required for future laser weapons. This project will demonstrate the creation of athermal windows and mirrors by combining existing near infrared high power laser component materials (such as fused silica) with other readily available materials (such as calcium fluoride or barium fluoride) that have negative dn/dT coefficients. The combiantion can be made athermal even though each component generally absorbs a different fraction of the laser beam and is heated to a different temperature.

Title:Highly Survivable and Scalable Unmanned-Vehicle Aided Autonomous Networked Systems
Abstract:We propose a paradigm shifting concept to the design, management, control and operation of autonomous intelligent networked C4ISR systems, based on the use of Unmanned Aerial and Ground Vehicles (UAVs and UGVs)). Mobile ad hoc wireless networks are currently generally unable to provide reliable high quality communications networking support to critical realtime flows for operations in a highly fluctuating and hostile environment. To correct this situation, we will develop in Phase I techniques for the dynamic positioning of UAVs and UGVs in multiple hierarchical orbits to best support mobile units during time periods of need. UVs will be positioned rapidly to provide coverage of segments that experience networking deficiencies. We will develop new network state metrics that are continuously monitored and used to rapidly locate UVs in the right place at the right time to maximize network connectivity, capacity and reliability, offering a solution that is adaptively hierarchical and thus highly scalable. We will use our innovative combined simulation/analysis approaches to develop a faster than real time simulator that will be used by military and commercial organizations to optimally and rapidly locate UVs to autonomously resolve network deficiencies and provide quality of service guarantees to multimedia network flows.

Title:SimQoS: A scalable, real-time capability for analysis of dynamic QoS provisioning in autonomous intelligent networked systems
Abstract:The objective of this SBIR effort is to develop a modeling and simulation capability that can be used to demonstrate that distributed, intelligent networked systems can perform cooperatively in very large numbers to satisfy time-varying QoS requirements of a diverse set of military applications. While technology research & development efforts can demonstrate viability of the concepts and technologies at the level of a few tens and even hundreds of elements, it is necessary that these systems scale to the many tens of thousands of nodes (including sensors, relays, transmitters, and receiver nodes) to fulfill the ambitious objectives for which they are being designed. This project will develop the architecture, methodology, models, and analysis capabilities to facilitate such scalability investigations. At the end of Phase I, we will demonstrate the simulation of a QoS network with more than a thousand nodes. This will be used to establish the validity of our approach for eventual development of SimQoS in Phase 2 to scale up to the tens of thousands of nodes. The eventual impact of this project will be to create an extensible framework for accurate & fast comparison of alternative QoS provisioning schemes in large autonomous, intelligent mobile networks.

Title:Multiple Target Laser Designator
Abstract:To address the Navy's need for a wide-area beam steering system for simultaneous laser designation of more than four targets, Physical Optics Corporation (POC) proposes to develop a new multiaperture, multiwavelength, Multiple-Target Laser Designator (MTLD). The proposed system is a novel full-scale laser designator system that integrates uniquely designed, aberration-corrected, high-gain multiband holographic telescopic optics (antenna) with an automatic target discrimination and tracking system, signal processing software and hardware, and high-speed data interfaces. The key advantages of this system over current systems include real-time multiwavelength, multiaperture transmit-receive target designation operation without the need for separate units; gain improvement of orders of magnitude, in a small-envelope, lightweight, low-cost system; highly efficient real-time background noise reduction through narrowband filtering of the unique hybrid transmission/reflection holographic antenna element, and camouflage penetration technologies. MTLD has no moving parts, which makes it rugged and particularly well suited to U.S. Navy applications. In Phase I, POC will demonstrate the feasibility of the MTLD by developing a laser designator system for five targets. Phase II will result in practical multi-aperture multiple-target (more than five dynamic targets), field-deployable, coded laser designation system, with performance superior to that of the best current technology.

Title:Rapid Target Designator for Simultaneous Laser Designation of Multiple Targets
Abstract:Small surface craft filled with high explosives and operated by terrorist groups represent a significant threat to docked and slow-moving naval ships. This proposal addresses a concept for a Rapid Target Designator (RTD) which is a single optical tracking/designating system that can effectively track/designate multiple targets simultaneously. This when coupled to one or more munitions platforms in a combined weapon system would potentially provide a timely and cost-effective protection system with an adequate stand-off range. The tracker/designator can be designed to handle at least 5 attacking craft simultaneously. The concept will address issues of (ship) motion stabilization appropriate to realistic sea-state conditions. The compact optical sensors suite/designator will ideally be mounted well above the deck to provide potentially good overall visibility of threatening craft at ranges of up to several kilometers. The sensor suite which utilizes COTS hardware will combine passive optical sensors with fast beam steering and a high repetition rate Q-switched YAG laser to attain the projected performance capabilities.

Title:Multiple Frame Assignment Tracking of Surface Targets
Abstract:Detection, surveillance, and defense against asymmetric threat scenarios such as small surface target swarms is an important area of concern. For homeland security, drug trafficking surveillance, and the protection of Navy assets it is necessary to track these highly maneuverable targets, perhaps in large numbers. This requires a tracking system that provides high-fidelity correlation and state estimation and exhibits graceful degradation in the presence of unique challenges such as limited target resolution, high false alarm rates, and temporal target occlusion. Numerica has developed state-of-the-art tracking systems for air and missile defense based on its Multiple Frame Assignment (MFA) data correlation method. To address the unique challenges of surface target tracking Numerica proposes to develop an advanced MFA multi-sensor surface target tracking system. The proposed Phase I prototype tracker will incorporate data from a suite of sensors such as SSR, IRST, and elevated IR/visible video imagery sensors. In addition novel algorithms will be formulated that significantly enhance surface target tracking performance: (1)fusion node aided signal processing to improve tracking in the presence of closely spaced objects; and (2) target discriminating feature aided tracking to improve data correlation and to discern sea from land targets.

Title:Real-time Multisensor Tracking and Correlation of Surface Targets
Abstract:Toyon Research Corporation proposes to develop a tracking system that is able to accept measurements from radars and EO/IR sensors to track surface targets. Our approach will be to use a Sequential Monte Carlo Technique, sometimes called Particle Filter, to filter measurements and compute association likelihoods. We will use the association likelihoods in an assignment matrix to perform data association using a modified Auction Algorithm. The particle filter will be designed to accept signatures as well as kinematic information, should it be available. We will explore several different options for simulating the motion of objects on the sea surface. This will include the assumption of a flat surface with process noise as well as approaches that seek to estimate the time-varying surface around each target. We will develop a prototype algorithm that we will evaluate and demonstrate using a computer simulation. We will do this in Phase I by making use of existing particle filter software that we have already developed for tracking ground targets. We propose to implement the filter in a Toyon-developed simulation, called SLAMEM, that has models of radars, EO/IR sensors, UAVs, and surface targets.

Title:MIMO Based Eigen-Space Spreading
Abstract:The multiple input multiple output (MIMO) concept applied to wireless data communications has been touted as a wireless revolution. Indeed, since its introduction MIMO communications has taken the commercial world by storm. The application of MIMO to military communications, however, has been lagging. Moreover, the exploitation of the new spatial dimension, to the signalling space that has traditionally consisted of time, frequency, and power, has to date gone untapped. In this work we will investigate means of leveraging the MIMO concept to achieve the ultimate in anti-jamming and low probability of detection/interception (AJ/LPI/LPD) communications. The proposed work is a radical departure from the traditional spread spectrum techniques (DSSS, FHSS, THSS) in that it will randomize the signal in space, as well as time and frequency. Space randomization will be achieved by transmitting on the spatial eigenvectors of the MIMO channel. Combination of this powerful technique with OFDM based modulation and traditional time and frequency spreading techniques results in a revolutionary secure mode of communications. Pulsar Communication Systems is uniquely poised to leverage the extensive MIMO experience existing within its staff and ready access to an existing MIMO OFDM testbed to develop a next generation modem for high threat environments.

Abstract:San Diego Research Center (SDRC) proposes to develop, validate and demonstrate an advanced OFDM Multiple-Input-Multiple-Output (MIMO) architecture for high mobility, military applications. The architecture will cover both PHY and MAC levels to ensure maximum support of multiple modalities on a single platform (i.e. individual communicator, cluster head controller, back-bone communicator, etc). The envisioned PHY will incorporate 30 to 40 dB of degrees of freedom (DOF) supporting multiple antennas to thwart advanced EW threats, while enabling robust, high-data-rate, and mobile tactical communications. The envisioned MAC will be tightly coupled to the PHY to facilitate maximum exploitation of the many PHY DOFs to support mission objectives. The proposed work will strongly leverage MIMO PHY and MAC work that SDRC is performing for other government customers.

Title:Universal MIMO-OFDM SDR for Mobile Autonomous Networks
Abstract:Agility, learning, and adaptability are three main elements for modern military communication systems. These systems must be capable of transparently "morphing" to support a multitude of modalities on a single platform by intelligently adapting to changing requirements such as environment variations and user specifications. Furthermore reliable communication of time-critical information in a robust jam-resistant communication network remains of utmost importance. Such an agile and cognitive wireless system is only possible with the innovative integration of state of the art techniques such as MIMO and OFDM in a highly advanced SDR framework. This versatility is enhanced by combining a programmable RF front-end, digital IF sampling and controllable spectrum selectively via direct digital frequency synthesis (DDFS) to provide an unprecedented degree of carrier frequency agility. Finally, the system must be outfitted with cognitive and cataloguing algorithms to allow it to autonomously learn and adapt to changing radio environments, changing terrain conditions, changing network topology, and changing QoS requirements. Pulsar Communications is uniquely poised to leverage the extensive wireless experience existing within its staff to develop a universal MIMO-OFDM SDR platform for mobile autonomous networks.

Title:Heavy Atom, High Density Polymers for Novel Propellant Binder Materials
Abstract:The development of improved, higher density solid rocket motor (SRM) propellant binders is a continued research goal of the DoD SRM community. Well developed state-of-the-art polyurethane binders have only moderate densities (~1g/cc) and are limited to energetic material loadings of less than 85 percent by volume. Increasing the density of the binder using higher density flouropolymers (up to 2.2g/cc) can significantly increase the performance of plastic bonded explosives (PBX). In an attempt to further increase the density of PBX binder, Foster-Miller proposes to investigate several possible routes to incorporate heavy atoms into the binder. These heavy elements will be added in a variety of positions along the polymer chains. During Phase I, Foster-Miller will demonstrate the feasibility of developing a much higher density (>3g/cc) binder system. Foster-Miller's chemists and consultants Prof. Harry Allcock of Penn State, and Dr. Claire Hartmann-Thomson of Dendritech have extensive experience in synthesizing these polymers. During Phase II, Foster-Miller will develop one of these candidate polymers into a demonstrable high density binder that meets all the high loadings, physical properties and stable lifetime required for an improved propellant binder.

Title:Synthesis of Energetic PrePolymers of Varying BAMO and NMMO or PGN Content and Structure
Abstract:Composite propellants and explosives typically consist of solid oxidizers, metallic fuels, and rubbery binders that provide the needed mechanical properties. Most binder systems are cured by the formation of urethane linkages by the reaction of oligomeric diols with diisocyanates or triisocyanates. A variety of available diols and isocyanates enables the formulation of binders with optimum physical properties for specific systems. New energetic ingredients are being investigated that have chemical properties incompatible with the polyurethane system. An alternative cure system based in the reaction azido-terminated oligomers with polyacetylenes to form polytriazoles has shown potential of stability with these ingredients . The objective of this program is to prepare novel polymer-based polyazides for this application.

Abstract:Physical Sciences Inc. (PSI) proposes to develop new synthetic techniques for end capping oxetane copolymers with BAMO. Our novel approach will utilize the development of a modified BAMO derivative that adds a single molecular unit of BAMO to the end of the polymer chain. By this new method, access to well-defined BAMO blocks of low concentration with excellent molecular control is possible. These blocks are used to crosslink other polymer chains and form a triazole cured polymer which is used as a binder in solid propellants. A series of BAMO and NMMO copolymers of varying polymer structure (random, random and blocked, blocked) and monomer stoichiometry (5/95, 20/80, and 40/60 BAMO to NMMO ratio) will be made in Phase I, using known and novel synthetic methods, to evaluate polymer structure-performance properties of the triazole cured polymers.

Title:Sub-Pixel Super-Resolution ATR
Abstract:It has long been known that (aided) target recognition based on imaging sensors is fundamentally limited by the number of pixels on the target imaged. Very roughly, at least 10 pixels are needed for detection, at least 100 are needed for generic classification, and perhaps 1000 are needed for recognition. While the details of this structure depend on specific sensors, targets, and sensing conditions, this general trend is universally observed in all domains of ATR. Doctrinal requirements of Total Information Dominance thus lead to massive deployment of sensors. How to gather, store, communicate, fuse, and analyze that vast flood of data in (near) real-time is then a formidable technical challenge. Moreover, given the lengthy DoD acquisition cycle, the fielded sensors are always inadequate - the warfighter needs yet more pixels, to see more clearly. Without improving the sensors, there still exists the opportunity to improve their imaging resolution in "software" - e.g., post imaging. The above analysis then points to the dramatic impact that post-imaging resolution enhancement, if available, can have on target recognition downstream. Video image resolution enhancement is the science/art of taking multiple frames from imaging sensor(s) that cover overlapping (but not necessarily identical) scene content, and integrating or merging the content for improved resolution - for scene analysis, surveillance, situation awareness, ATR, and other applications. Fusing images for enhancement from the same sensor (under the same conditions) reduces to the problem of subpixel registration. For successive frames of a video camera in which there is subpixel dislocation of objects in the visual field, due to relative motion (even due to camera jitter), this provides an opportunity to increase resolution. FastVDO has developed advanced superresolution technology, as well as ATR technology, which are ready to use.

Title:An Integrated InGaAs PIN and Bolometer Focal Plane Array for Combined Thermal Imaging and Covert Three Dimensional Imaging
Abstract:Sensors Unlimited, Inc. will develop and deliver a two-color camera featuring simultaneous, coplanar imaging in both the short-wave infrared (SWIR, 0.9 mm - 1.7 mm) and long-wave infrared (LWIR, 8 mm -12 mm) wavelength bands. The camera's focal plane array will combine detection of both spectral regions in the same uncooled monolithic imager with a single readout integrated circuit for snapshot acquisition of all pixels. Each pixel will contain two detectors: an indium gallium arsenide photodiode for SWIR and a microbolometer for LWIR. The integration of the two detector types will be accomplished by fabricating both on the same indium phosphide substrate. This innovation will simplify existing system designs for image fusion by combining the imagers in the same optical plane. To identify the target objects, the same imager can detect reflected light in the SWIR band and use the thermal band for temperature signatures. In addition, the high-speed performance of InGaAs photodiodes enables future enhancement with LADAR. Our unique SWIR/LWIR 128x128x2 element camera will be the final product of Phase III. In Phase I, we will demonstrate a combined single-element SWIR/LWIR detector. In Phase II, we will demonstrate a 16x16x2 combined SWIR/LWIR focal plane array.

Title:Computer Optimized Design of High Performance Vacuum Electronic Devices
Abstract:Development of efficient, complex devices requires consideration of many inter-related parameters. For high power RF devices, electron beams in electrostatic and magnetostatic fields interact with RF fields in resonant cavities or propagating along a slow wave structure. The interaction physics is nonlinear, and time, frequency, material and temperature dependent. In the past, individual components of complex structures were developed independently using manually generated input and relying on the skill and experience of the designers. With increased complexity, the allowable parameter space for the design becomes too large for manual investigation. The development of advanced optimization and tolerance analysis algorithms now facilitate computer optimized design in an efficient, cost effective manner, providing the design codes are modified appropriately. Further, global optimization now becomes possible with several analysis codes linked to share common data. This program will implement advanced computer optimization and statistical tolerance algorithms into computational design codes for developing high performance vacuum electron devices producing RF power. The routines will include consideration for dimensional tolerancing, and material and thermal properties in the design analysis.

Abstract:High performance vacuum electron devices are widely used radar, communications, sensors, and navigation systems, where they provide an efficient and reliable source of microwave power. For many applications it is extremely important that the device be optimized to provide improvements in efficiency, power, and tolerance insensitivity, which significantly impact system performance, lifetime, reliability, and cost. Modern stochastic optimization strategies provide a powerful approach to obtaining an optimal design in a variety of disciplines. To be effective in vacuum electronics design, however, appropriate methods must be identified, supporting technology such as adaptive mesh refinement techniques must be improved, and tools must be better integrated. A prototype design system will be built to address this need and used to study optimization and adaptive mesh refinement methods for application to the CHRISTINE and MICHELLE codes. The system will extend the existing MICHELLE user interface and integrate other existing components to minimize development work, and be applied to the gun and slow-wave circuit of a traveling wave tube. A successful project will establish the viability of the system architecture and develop technical options for optimization and adaptive mesh refinement that will be valuable for the Navy, and be the focus of future research.

Title:Ultra-Low Heat-Leak YBCO Superconducting Leads for Cryoelectronic Applications
Abstract:The overall goal of this project is to develop multiline patterned YBCO leads on commercially available flexible substrates, and show that these leads can be used to deliver the low currents and signals necessary for 4K superconducting electronics to operate with a dramatically reduced thermal load. The project will focus on depositing YBCO thick films on yttria stabilized zirconia flexible sheets that are thin enough to conduct little heat. A key problem to solve is to find a workable diffusion barrier that would allow in-situ reaction of the cuprate material without cross-contamination or excessive heat transport. The method will allow patterning of conductor lines which are size-compatible with conventional PCB technology. Extensive testing will be done at DC and RF frequencies, on a two-stage cryocooler and in vacuum.

Title:Thermal Management Leads
Abstract:In this Navy phase I SBIR effort, Tai-Yang Research Company (TYRC) of Delaware proposes to design, fabricate, and test a prototype high temperature superconducting (HTS) current lead using state-of-the-art second-generation YBCO coated conductor. The proposed YBCO current lead's (4 K) heat load will be over two orders of magnitude SMALLER than any existing commercial HTS current lead based on Ag-Au alloyed Bi-2223 powder-in-tube tape (PIT) or melt-cast Bi-2212 tubes. The proposed YBCO current lead will be compact, flexible, and mechanically robust making it an ideal choice for military applications operating in harsh environments.

Title:Intelligent Acoustic Source Detection/Recognition for Noisy Environments
Abstract:To address the U.S. Navy needs for an intelligent, acoustic recognition system for extremely noisy environments at military installations, on ships, and in vehicles, Physical Optics Corporation (POC) proposes to develop a new intelligent acoustic threat detection/recognition system for extremely-low SNR environments; this system will be based on a neural network source separation structure capable of both robust multiple noise separation and reliability quantification. It will detect threats, separate targets, and quantify confidence by means of a multiple-neural net architecture. In addition to target separation, it will determine high-resolution acoustic source bearing, and information on the location, speed of movement, relevance (direction), and number of sources of each distinct target sound. The proposed technology will be flexibly deployable for data fusion with a hybrid array of hydrophones, vibration sensors and other acoustic transducers. In Phase I POC will demonstrate the feasibility of recognizing discrete sounds at 20 dB more than 95% of the time. In Phase II, POC will optimize a prototype system with a sensor array, and test it in context similar to a military installation or naval base.

Title:Acoustic Security Detection System
Abstract:Acoustic sensors can be a valuable aid to providing security surveillance of military bases, ships, and warehouses. To do so, the sensor system must be able to differentiate between "normal" sounds of nearby activity or the natural environment, and "security-breaching activity." SARA applies an inverse approach to this problem: An acoustic sensor that records and maps the features of every sound heard. After a period of adapting to a new environment, the system will report any new sound types heard. Therefore, any unusual sound triggers an alarm. This approach removes the need for tedious training of many samples of a large library of sounds, and allows the sensor to be deployed to entirely new environments or changing environments, without retraining or study of the acoustic environment. Sounds are characterized by signal features developed for voice recognition, music library searches, even from radar signature identification technology, to select a robust and unambiguous set of features. Operational factors, such as time-of-day and location of sound, are used to further evaluate the alarm condition. The proposed hardware for this sensor system takes advantage of sensor array processing techniques, and SARA's unique all-weather windscreen is used.

Title:Uncertainty Management for Teams
Abstract:One of the largest challenges facing our nation's current and future military systems is how to best make use of the remarkable proliferation of information technologies to support human decision processes. There is a sense of extraordinary potential for advancing our collaborative decision capabilities in particular, given the unparalleled reach and richness of information today. In order to tap the full potential, we need to improve our understanding of how collaborative groups jointly construct and communicate meaning that the individual members derive from the information at their disposal. Existing work on the problem has primarily focused on the information flow of content. Yet, in addition to content, team members also experience and transmit varying degrees of uncertainty with respect to the content. And the ways in which teams manage this flow of uncertainty can have a large impact on how they collaboratively observe, orient, and decide. In the Phase I effort, we will employ CTA methods to develop a model of uncertainty management for teams (UMT). The UMT Model will guide display designs for use with an existing collaborative tool. Concept maps may be especially suited to achieving collaborative understanding and uncertainty reduction.

Title:Shared Intelligence Evaluation VisualizEr (SIEVE): Web-based threat assessment for cross-cultural intelligence analysis
Abstract:Accurate cross-cultural intelligence analysis of rapidly developing threats is extremely difficult when the environment is characterized by dispersed and fragmentary data, cross-cultural differences, and inherent cognitive predispositions to exhibit biased information integration. The objective of this Phase I proposal is to integrate the results and lessons learned from a series of research programs to create a new tool to support cross-cultural intelligence analysis called SIEVE (Shared Intelligence Evaluation VisualizEr). SIEVE integrates notions from these different efforts as well as novel notions for the reduction of decision bias, to create a powerful threat assessment system for cross-cultural intelligence analysis. SIEVE creates a Web-based coordinating representation for analysts' activities populated with seven key design features derived from a cognitive model. These design features specifically address the problems inherent in information integration by physically separated analysts, cross-cultural exchange of meaning, and biased hypothesis exploration and decision making. This proposal lays out the elements of the design of such a system, and it details the tasks necessary to develop a prototype.

Title:Agent-based Simulation of Shipboard Manpower & Personnel (M&P) Behaviors
Abstract:The number of responsibilities a sailor has on a ship is increasing while the amount of time available to complete those tasks is fixed. Continuous overloading of sailors with watchstanding, operations or maintenance duties can lead to degraded performance of both the battlegroups' mission and ship operations, coupled with increasing sailor burnout leading to a decrease in personnel retention. Understanding the effect mission requirements has on the behavior of a sailor and visa-versa how does the sailor behavior impact the mission is of great importance especially given tighter budgets, longer deployments and possibly lower levels of recruitment. The use of computational models that can integrate traditional Operations Research (OR) approaches to ship operations with the sciences of Complex Adaptive Systems (CAS) represents a potentially significant contribution to support the process of shipboard manpower and personnel system planning. Modeling shipboard personnel systems faces significant challenges before its true vision can be fulfilled. A ship is a complex adaptive system; the number, diversity and connectivity of the elements means the ability to predict dynamic structural behavior through the detailed analysis of individual elements is low. A holistic, network-oriented view of the ships operations is necessary.

Title:Personnel Flow Management Toolbox: A Complex Adaptive Systems Approach
Abstract:Every year, billions of dollars are lost to bad decisions. Without the proper tools to analyze and evaluate decisions before implementation, even more money will be lost. Decision problems that must contend with autonomous entities are the areas most subject to erroneous decisions due to the complexity and cost-prohibitive nature of extended simulation and testing of hypothetical decisions. Advances in the area of Complex Adaptive Systems show that simple abstractions of complex phenomena can produce generalized results applicable to broad classes of problems, thus creating opportunities to analyze complex multi-agent problems without full-fidelity simulation. In order to address the need for a multi-agent discrete event simulation tool, with specific applications to the management of shipboard manpower and personnel, Orbital Research, Inc. proposes the development of a graph-theoretic multi-agent simulation tool that will incorporate analysis tools based on Complex Adaptive Systems theory. This Phase I work will: 1. Develop a generic multi-agent simulation tool based on graph-theoretic abstractions of real-world environments. 2. Investigate the applicability of Complex Adaptive Systems theory to the analysis of multi-agent systems. 3. Perform a proof-of-concept simulation of a real-world multi-agent scenario and correlate the data, showing that the abstracted simulation produces the same overall trends.

Title:Toolset for Content-Based Automated Communication Analysis
Abstract:Teams play an increasingly critical role in complex military operations in which technological and information demands require a multi-operator environment. However, verbal communication, which represents a rich source of data on team cognition and collaborative thought, is notoriously difficult to analyze. We propose to develop a set of tools for the automatic analysis of verbal communication data in order to assess and monitor individual and team knowledge. The toolset uses a Latent Semantic Analysis (LSA)-based intelligent software agent for embedding automatic, continuous, and cumulative analysis of oral interactions in individual and team operational environments, It further includes additional statistical measures of sequential team behavior and a running task model of team cognition and process behavior (C3TRACE). In Phase I, the project will identify existing communication analysis techniques, test these techniques on existing communication data and demonstrate and report on their reliability, validity and effectiveness at quantifying aspects of team performance and situation awareness. Phase II and beyond will develop the techniques into a robust system for automatically monitoring and providing feedback on teams and individual performance and test them within operational contexts. The full system provides a complete communication analysis pipeline, automatically converting speech into performance measures in real-time.

Title:Automated Communication Analysis for Interactive Situation Awareness Assessment
Abstract:Military and intelligence operations are highly dependent on the presence of cohesive and effective teams to carry out their missions. In these team operations, rapid and accurate development of a shared, accurate picture of the tactical situation is critical for effective team operations. This Phase I SBIR seeks to employ state of the art techniques in situation awareness theory, cognitive task analysis, communication analysis, and Social Network Analysis (SNA) to develop and validate a computational model of team SA. This computational model can be used to both predict and assess team SA. The Phase 1 program will result in the development of an initial model of the formation of Team SA in a military tactical domain based on SA communication analysis, team member experience and team tasks being performed. This model could eventually be used as a diagnostic tool to predict team SA for a wide variety of teams when considering the impact of changes in the factors in the underlying model.

Abstract:ITN will leverage its patented solid-state flexible thin-film secondary-lithium-battery and photovoltaic (PV) technology to develop enabling innovative integrated power systems for man-portable applications. This power system will provide 50 W for up to 4 hours with solar energy conversion, recharging, power management and power storage. ITN will work with our production battery company, Infinite Power Solutions, and our production thin-film photovoltaic company, Global Solar Energy, to develop an integrated flexible PV/secondary battery power system with very high power to weight and extremely long cycle life. Our thin-film battery is the only technology with the demonstrated 100,000+ full depth of discharge cycle-life needed to last the lifetime of the system. Combined with our thin-film PV, which has the lightweight form factor and high efficiencies needed for portability, ITN will develop a self-recharging power system to operate field equipment such as two-way radios, global positioning systems, computers and field sensors. This revolutionary technology is projected to weigh just 1580 g and is designed to replace or augment the standard non-rechargeable 1240 g BA5590 battery used extensively by our military today. This slight increase in weight is well substantiated when all multifunctional power system factors are considered.

Abstract:This Small Business Innovation Research program is to develop a novel technology for fabricating amalgamated thin-film photovoltaic solar cell/lithium-ion battery energy devices. Such devices involve the development of Reveo's novel thin film solar cells and Reveo's novel thin film lithium-ion batteries. The solar cell and battery are nicely organized together through a novel charging/discharging controller for hybrid systems to function as a single unit for providing power and charging the battery in daylight, while continuing to supply electric power via battery discharging in darkness. The proposed technology takes advantages of dye-sensitized solar cells and overcomes the technical problems associated with thin film dye-sensitized photovoltaics and lithium-ion batteries. The result of the combined systems will be used to power a variety of portable electronic devices. Phase I activities will include designing and fabricating a power supply unit of the hybrid device suitable for portable application. The unit will provide 50 watts power at 28 volts in either the photovoltaic/charging or battery-only mode. The battery should be fully charged within 6 hrs even in cloudy daylight. Phase II activities will involve optimizing and delivering a portable, self-contained power system to operate actual devices comparable to or exceeding conventional batteries.

Title:Optimized, Free-Radical, Large-Batch Synthesis of Microphase-Separated Copolymer Electrolyte
Abstract:Many Naval capabilities are hamstrung by the need for lighter more powerful batteries, particularly propulsion systems of unmanned surface vessels and underwater vehicles. Lithium-ion batteries with specific energy of 115 to 125 Wh/kg have been demonstrated at the 1 and 100 Ah class size, but significant barriers prevent their safe use as power sources for high-energy, large-scale applications. Due to poor stability and low Li transference number, cell power fades under high charge/discharge rates; sometimes leading to thermal runaway and uncontrolled venting of the cell. Lighter, higher voltage batteries could meet these needs if a stable, highly conductive thin film electrolyte could be manufactured, that reduced the amount of electrolyte and spacer materials. This program will capitalize on the recently reported success of block copolymer based solid-state electrolytes to support both liquid-like conductivy and solid-like mechanical behavior, and develop an economical synthesis approach that is amenable to large-scale production of thin film electrolytes. Synthesis routes starting from inexpensive materials are proposed. Their systematic scale up will be achieved stepwise using increasing larger batch reactors and the electrochemical characteristics of the resulting electrolyte films will be investigated in-house using a standard battery cycler and electrochemical impedance analysis. The proposed program will culminate with the production of safe, solvent-free electrolytes with superior conductivity critical to the development of large, safe, economical rechargeable batteries.

Abstract:A novel highly integrated electrically driven propulsor is proposed to increase effectiveness and payload fraction while significantly reducing cost of future Navy and commercial undersea and surface vehicles. High power density is achieved with a rim driven architecture utilizing an advanced motor design and close integration with drive electronics and control. The advantages of this highly integrated package will benefit a variety vessel propulsion configuration such as distributed pump jet and podded propulsion systems. Commercial and military surface transport and supply ships, undersea surveillance and survey vehicles will benefit as well as Navy submarine and surface combat vessel.

Abstract:Triton Systems, Inc. proposes to develop a Laser Hybrid Welding (LHW) capability with an associated thermal image and gas shielding control system, for high quality and cost-effective joining of large titanium structures. The LHW is a recently developed technology to weld large metal and alloy structures in which the combination of a laser beam and arc welding enables the joining of large scaled complex structures. The proposed capability will allow the Navy to efficiently use affordable large titanium structures for aircraft, ground vehicles, ships and submarines. Triton's innovative LHW system will comprise a laser, an arc welder, and a closely monitored and feedback controllable thermal image and gas shielding system. The laser offers a deep penetration in the joined work piece with a small Heat Affected Zone (HAZ). The arc provides enhanced capability for welding complex joint configurations and further penetration at high tolerances. This combined welding process is believed to be the leading technology in the future for the joining of large titanium and other alloy structures.

Title:Development of Flux-Core Electrodes for Welding Large Titanium Structures
Abstract:Arc Welding of titanium has always been a challenging engineering problem, requiring shielding from atmospheric contamination (e.g., oxygen and nitrogen) until the metal is below approximately 400oC. Small titanium weldments are typically welded in inert gas chambers. However chambers are impractical for welding large structures. Instead, auxiliary shielding devices (e.g., trail- and back-side shields) must be provided, which result in significantly higher costs, and require a high level of skill. Thus, developing a method of producing high-quality titanium welds, without the need for auxiliary shielding devices, would provide a significant cost benefit for fabricating large titanium structures. One potential method of eliminating the need for auxiliary shielding devices is to develop a flux-cored consumable to shield the weld metal with a blanket of slag. WeldQC, Inc. proposes to evaluate the feasibility of developing flux-cored consumables for welding titanium using the GTAW and FCAW processes. The proposed effort will address the needs of the SBIR Topic No. N04-124 "Joining Methodologies for Titanium Alloys" by developing a cost-effective method of welding large-scale titanium weldments, which have acceptable levels of interstitial elements and mechanical properties. WeldQC, Inc. has formed a team with Colorado School of Mines (CSM), The Stoody Company, and Ingalls Shipbuilding.

Title:High Power Density, Thermally Controlled Capacitors for Power Electronics Applications
Abstract:The Navy is moving forward with all-electric hybrid ship and vehicle propulsion systems, rail guns, directed energy weapons, and electromagnetic launchers and sensors. Cryogenically cooling the power electronics in these systems will facilitate the transition to these new technologies, providing exceptional performance and efficiency, even when the refrigeration penalty is taken into consideration. Significant reductions in size and weight can come from the use of cryogenic capacitor banks, which could offer up to a 75% decrease in size and weight over conventional capacitors. Cryogenic capacitors also promise extremely low losses, possibly well below 1%. Such a system could also be configured to operate in environments with ambient temperatures of up to 200C, while still allowing for the use of superconducting buss work. MTECH Laboratories, a pioneer in Cryogenic Power Electronics, is uniquely qualified to develop these advanced capacitors. The Phase I effort will consist of a feasibility study and design work, to be followed by a prototype demonstration in Phase II.

Title:Composites of Phase Change Dielectrics and Glass-ceramic for High Power Density Capacitors
Abstract:High-temperature, high-energy density capacitors are essential for state-of-the-art all-electric equipment including rail guns and other weapons, electromagnetic launchers, sensors, vehicles, and ships. High energy density capacitors can only be achieved using materials with both high dielectric permittivities and high dielectric breakdown strengths. In this program TRS Technologies and The Pennsylvania State University propose to develop high-temperature capacitors exhibiting high-energy storage using on phase change dielectric ceramics that have been demonstrated to exhibit energy densities on the order of 20 J/cm3 and using glass ceramics in conjunction with hot isostatic pressing technology (HIP). Defect free antiferroelectric-to-ferroelectric phase-change materials containing 10 ~ 40% glass-ceramics are projected to have dielectric constants of ~1000 and dielectric breakdown strengths on the order of 1000kV/cm, resulting in energy densities as high as 40J/cm3. Considering factors such as packaging losses, practical energy densities of ~12J/cm3 are projected for capacitors operating at about half of the dielectric breakdown strength. Hot isostatic pressing will be used to fabricate the nearly flaw-free ceramic ?glass-ceramic 3-3 composites required to realize these energy storage levels.

Title:Active Control of Lean Blowout Using an ANN-Based On-Line Direct Controller
Abstract:Combustor Lean Blowout (LBO) is a significant challenge in modern military gas turbine combustors. LBO can occur either during rapid engine deceleration or during operation at idle conditions with water/steam ingestion. Current practice is to design adequate safety margins to avoid the onset of blowout. However, significant engine performance improvements can be realized though the development of a system that identifies and prevents blowout. Such a closed-loop, active control system is proposed for development in this SBIR. In Phase I, we will focus on sensing LBO and its precursors. Detailed experiments will be conducted to identify chemiluminescence and pressure signal characteristics that precede blowout. A prototype gas turbine injector being developed for JSF application under Navy sponsorship will be used to provide a realistic and representative test environment. In Phase II, the complete system will be developed and demonstrated. A novel Artificial Neural Network (ANN) on-line direct controller will be developed to identify LBO precursors in real time and control the fuel injector response. An ANN-based direct controller does not require a system model and the controller automatically adjusts to changing dynamic system conditions. For LBO control, an innovative plasma-based flame stabilization system will be incorporated into the fuel injector and used to stabilize the flame beyond the lean blowout limits by introducing a corona discharge at the injector exit.

Title:Precursor Detection of Combustion Instability
Abstract:Combustor blowout instability develops under lean operating conditions displaying complex, low frequency thermo-acoustic fluctuations. In thermal pulse combustors, these oscillations can become chaotic. Detecting these changes in combustion dynamics prior to blowout has the potential to yield useful monitoring information and feedback for active control of instability. As the fuel/air ratio at which blowout occurs is uncertain, understanding how these precursors to combustion instability change with fuel composition, ambient conditions, pulsation amplitude, and combustor age is of fundamental performance. The traditional approach taken by combustor designers is to build sufficient margin into the design to prevent blowout under worst case operating conditions. Rather than suppress or avoid possible nonlinear behavior, we will investigate the possibility of exploiting the nonlinear nature of the combustion around blowout to reduce operating margins while maintaining stability or extend the limit of lean operability. Recent advances in nonlinear dynamics have led to the development of analysis techniques that are useful for gaining insight into the behavior of complex physical processes. These techniques will be used to analyze acoustic, chemiluminescence, and temperature oscillations measured in a thermal pulse combustor and identify precursors of combustion instability. Precursors would be identified by searching for qualitative changes in statistical behavior of combustion dynamics reconstructed from experimental data using time delay embedding. Nonlinear signal processing technique suitable for nonlinear and nonstationary processes will also be used to isolate intermittent and transient precursor signals in noise.

Title:Automated Launch and Recovery of Un-tethered, Mini-Unmanned Underwater Vehicles from Unmanned Surface Vehicles
Abstract:Unmanned Underwater Vehicles (UUVs) are being developed for mine hunting operations to provide more effective mine detection and neutralization at lower risk to than conventional mine hunting methods. Although UUVs show promise, they must be small and highly maneuverable, which limits their range and mission duration. An Unmanned Surface Vehicle (USV) can carry several mini-UUVs into an area of operations, thereby significantly increasing the on-station time of the UUV by eliminating the requirement to expend power to travel to the operational area. The USV can also provide an on-site station for recharging batteries. Bluefin Robotics Corp. intends to partner with Brooke Ocean Technology Ltd. (BOT) and proposes to develop a system capable of automated launch, recovery, recharging, and data transfer for small UUVs that are deployed from USVs. Bluefin's expertise with UUVs, including mini-UUVs, vehicle guidance and docking systems and BOT's expertise with UUV/USV launch and recovery and automation creates a team that is well qualified to complete this project.

Title:Automated Launch and Recovery of Un-tethered, Mini-Unmanned Underwater Vehicles from Unmanned Surface Vehicles
Abstract:Current development of Unmanned Surface Vehicles (USVs) includes the exploration of various mission capabilities. One mission capability desired of future USVs is mine hunting, using Unmanned Underwater Vehicles (UUVs) to perform this task. Candidate USV/UUV future platforms to perform completely unmanned UUV launch, recovery, battery recharge, and data extraction of mine hunting include the Spartan USV and the REMUS UUV. REMUS UUV R&D test deployments to date have been from manned vessels. Similarly, USV R&D test deployments of the Spartan have not yet completely demonstrated the autonomous launch and recovery of a UUV, such as REMUS. SEA CORP will investigate the application of innovative technologies to perform the completely autonomous launch and recovery of a UUV from a USV. The SEA CORP solution will address four specific UUV processes required: Launch, Recovery, Data Extraction, and Make Ready. Reliability, cost, and producibility are key factors that will be investigated for this application.

Title:Unmanned Surface Vehicle Stabilization, Navigation and Collision Avoidance
Abstract:A system to facilitate navigation of a USV (Unmanned Surface Vehicle) in a maritime seaway is proposed. The system will provide 3 functions: 1. Stabilization of the hull to prevent excessive deck motion or capsizing, 2. Determination of optimal course and speed for the given wave, wind, and current environment, 3. Avoidance of Collisions with flotsam or other vessels. The system processes radar and deck motion data as sensed by an Inertial Reference Unit (IRU) and commands the ships attitude control and propulsion devices. The proposed research builds on previous work by the investigators in researching deck motion prediction systems for shipboard helicopter landing, and developing navigation and stabilization systems for autonomous helicopters and AUVs (Autonomous Underwater Vehicles.

Title:Unmanned Surface Vehicle Autonomous Maritime Seaway Navigation
Abstract:The U.S. Navy is developing unmanned vehicle technologies for air, sea and undersea applications. Many technologies will have to be developed to replace functions that are now performed by human operators. Additional sensors will be required to provide the vehicle controller with information that a human would have sensed, and algorithms will have to be developed to react to the sensed information. One of the primary limitations of a manned vessel that will not exist on an unmanned vessel is motion sickness incidence of the crew. The discussion changes from needing to ensure that the crew can perform their duties and remain healthy in heavy seas, to ensuring that the unmanned vessel can maintain structural integrity, hydrodynamic stability, and directional control in a seaway. Beyond simply slowing the vehicle to reduce accelerations in heavy seas, the unmanned vessel will have to determine how to manage the trade off between efficiency and speed to achieve its destination.

Title:Near-Wall Turbulence and Skin Friction Measurements Using Ionic Polymer Sensors
Abstract:The purpose of this proposal is to demonstrate the feasibility of using novel ionic polymer sensors to measure flow-induced skin friction. Knowledge of the skin friction at the hull / water interface is critical to propeller and propulsion system design. Also, knowledge of the mean and fluctuating wall shear stress is important for understanding the details of flow separation and flow-induced noise. More importantly, a robust technique for measuring wall shear stress is needed to assess the effectiveness of new friction-reducing techniques, including the use of lubricants and micro-bubble injection. Current techniques to measure skin friction are hindered by several key limitations, including high cost, difficulty of implementation, and susceptibility to seawater corrosion. By contrast, ionic polymer sensors are low cost, thin flexible polymer membranes that can be affixed directly to the surface of a vessel with no modifications. Furthermore, they respond directly to flow-induced shear, thus making them ideal candidates for analyzing the effectiveness of friction-reducing treatments. Initial results with ionic polymer sensors reveal that the sensor output shows excellent correlation to theoretical predictions of skin friction. The Phase I effort will expand on this work by validating ionic polymer skin friction sensors using particle image velocimetry.

Abstract:With the development of a portable multi-wavelength laser processing system, cleaning, cutting, joining, polishing, and cladding processes as well as the capability to produce unique surface coatings with ultra hard and ultra tough characteristics in a single portable unit become possible. These processes can be done in a quick, reliable, and economical manner. This system will include multiple lasers of different wavelengths ranging from the UV to the IR. The specific wavelengths will be based upon Turchan's QQC division's patented multiplexed laser synthesis technology. In Phase I of the development, Turchan Technologies will configure, integrate and demonstrate a single wavelength system capable of significantly modifying the characteristics of a steel coupon or sample part as well as a plan for condensing that system into a portable unit. There is no doubt that this technology would be invaluable to the DoD to enhance the properties of components such as gears, bearings, turbines, etc. on many of their ships and vehicles as well as other machinery.

Title:Radar Detection Performance Model For Low RCS Maritime Targets
Abstract:Threat maritime surveillance radars provide an all-weather, day/night performance capability to detect and track US ships, and hence can adversely affect the Navy's Littoral Warfare capability. To help mitigate this threat, it is desirable to design US vessels with reduced radar cross-section (RCS) to minimize their signature. However, current maritime surveillance radar models are not accurate enough to quantitatively assess the tradeoffs between the complexity and cost associated with reducing ship free-space RCS and its associated measure of effectiveness, i.e., its benefit in terms of reducing ship detectability by threat radars. Dynamics Technology, Inc. (DTI) will develop a high fidelity radar performance simulation that accurately predicts detectability of small RCS ships and craft on the ocean surface. In Phase I, we will define the requirements and design of the simulation, adapt DTI's existing methodology within our validated Periscope Detection Radar Model to the low RCS surface target domain, and build a prototype performance simulation to elicit feedback and guide Phase II simulation development.

Title:Detectability of Low Radar Cross-Section (RCS) Targets at Sea
Abstract:Future Navy ships operating in littoral waters must have low radar cross-section (RCS). Defining these requirements demands an accurate radar detectability model to give ship designers the tools to make appropriate trade-offs. The key to assessing the detectability of ships is to accurately model site-specific clutter and derive detection statistics from an accurate interference and signal model. Information Systems Laboratories, (ISL) proposes to integrate a Navy-developed ducting model into its Splatter, Clutter, And Target Signal (SCATST) model to predict site-specific clutter with high fidelity and apply the results to the problem of accurate ship detectability. The SCATST model is a fully polarametric radar phenomenology model which takes into account the complete scattering environment including multipath, bistatic scattering, and off-axis components over both land and sea. In this Phase I program, a ducting model will be integrated and the resulting product assessed for sensitivity to choice of environmental parameters. This effort will establish the feasibility of the approach for achieving the accuracy required.

Title:Energy Finite Element Analysis System
Abstract:The U. S. Navy has identified the need to develop accurate noise and vibration prediction methods for ship structures. Since testing at the prototype level is time-consuming and expensive, analytical modeling is used to reduce the need for physical testing. It is critical that the analytical predictions be both accurate and timely to avoid the need for redesign, which can be even more costly. Therefore any improvements to existing modeling and prediction capabilities that would increase accuracy or improve ease-of-use would result in large cost savings for the Navy. Cambridge Collaborative proposes to develop an Energy Finite Element Analysis (EFEA) software package that provides 1) accurate predictions of energy distribution across structural subsystems, 2) radiated noise signatures, and 3) interior noise predictions. Our proposed EFEA software will be integrally linked to our existing statistical energy analysis (SEA) commercial software package, and will be able to integrate with finite element, boundary element, and other Navy ship design software products. It will take advantage of our existing graphical user interface with 3D design and presentation capabilities. It will also incorporate innovative research performed under this proposal in the areas of partial fluid loading, mixed phase materials, and free surface radiation effects.

Title:Energy Finite Element Analysis System
Abstract:New Naval initiatives, like the DD(X) program, impose stringent noise and vibration targets, and require assessment and reduction of noise due to machinery, flow, and propulsion. A typical surface ship structure exhibits thousands of normal modes below 30Hz. Thus, the frequency range of interest from signature and hull vibration objectives extends far beyond what existing finite element based methods can predict. High noise levels in living quarters and in working spaces due to acoustic emissions from machinery and operating aircraft creates habitability concerns which must also be addressed in new surface ship designs. Recently, an Energy Finite Element Analysis (EFEA) and an Energy Boundary Element Analysis (EBEA) formulation have been developed by the PI of the proposed project, and they have been applied for computing the vibration of submersible vehicles and the associated radiated noise at frequencies beyond the limits of conventional finite element methods. In addition to the Naval applications the EFEA and EBEA methods have been applied successfully in predicting vibration and acoustic fields in aerospace and automotive applications. The proposed project will lead to the development of an EFEA and EBEA system for the analysis of full scale surface ships and submarines in a robust and user friendly manner.

Title:Modeling the Detectability of Small Targets at Sea
Abstract:Search and target acquisition models are essential tools for designing imaging sensors and systems such as small sea craft. They also form the core of modern, system level, force-on-force simulations, commonly called "wargames." Where engineering models seek to calculate target detectability to a high degree of certainty, wargaming models are much more centered on the search process. In a process known as Simulation Based Acquisition, wargames provide quantitative measures of the military utility of a future system. However, the target acquisition models within wargames are inaccurate when considering modern imaging sensors and targets with reduced signature, due to the lack of detail in describing the sensor, the target, the background and the environment, and to the relatively simplistic algorithms typical of these simulations. This effort proposes an approach for greatly increasing the accuracy of the target acquisition module applied to force-on-force simulations. We will expand the data fidelity of all aspects of target acquisition and update the algorithms to make best use of these new data. The principle challenges are defining datasets that may be reasonably available and designing and ensuring that the algorithms remain sufficiently fast for real-time wargame operations.

Abstract:JRM Technologies proposes to develop innovative new vision- and figure-of-merit-based models for search and target acquisition performance prediction of EO-IR sensors against small tactical sea-based targets. These models will directly address the limitations of traditional land-based models like the US Army NVTHERM model based on the 1950's Johnson-Criteria. The Phase I effort will design algorithms with government-oversight that are most suitable for implementation in a Phase II effort. The Phase I design effort will specifically address: (1) Transient as well as stationary sea-based EO and IR clutter; (2) Image-based models - like JRM's Target Acquisition Agent - designed to operate on radiometrically correct synthetic sensor imagery to predict both realistic detections and false alarms; (3) Advanced EO-IR sensor effects modeling to account for the effects of MTF and detector noise in both FOM and vision-based models;

Title:Recovery Algorithms for Ship Survivability
Abstract:The proposed work will evaluate use of a Reference Model Based System (RMBS) integrated analysis and information management approach, originally developed for the power utility industry, for use in shipboard system recovery analysis and survivability management. The approach derives spatial and functional interdependency information directly from digitally displayed system diagrams and then uses that information to structure integrated: (1) Linear graph theory based generic first principles analysis, (2) Topology based optimal reconfiguration and system wide reliability analysis, which could later be extended to perform "Total Ship" survivability analysis, and (3) Component level discrete control and switching simulation. Phase I work will be based on modification and extension of existing RMBS software developed by EDD for EPRI. Work will include development of a demonstration model that includes AC and DC electrical distribution, power converter cooling, chill water, firemain and compartmentation. Example recovery analysis and control simulation will be performed for several damage scenarios with varying ship mission priorities. Damage will include standard damage control and casualty control exercise scenarios, and include a total ship survivability exercise that includes simultaneous casualties to multiple systems and multiple compartments.

Title:High Performance Fuel Based on Nanoparticulate-Hydrocarbon Hybrids
Abstract:This proposed Small Business Innovative Research (SBIR) Phase I addresses the development of advanced hybrid fuels and determination of their suitability for selected high thrust propulsion applications. The hybrid fuels will consist of metal oxide coated metal nanoparticles suspended in hydrocarbon fuel. Similar propellants have been utilized in rocket and missile propulsion systems as gels. These formulations enhance the density and specific impulse of the base propellant and also impart the desirable properties of gels to fuels. In the proposed Phase I, fuels for various high thrust applications (e.g., gas turbine, automobiles, generators, auxiliary power units) are sought. Such fuels will improve energy density and enable reduction in fuel weight and combustion chamber size. Phase I will consider a matrix of formulations drawn from various metal nano-particulate species. Initial testing of preferred fuels will be conducted. Properties of candidate formulations will be calculated and fuels with the desired properties prepared and initial properties measurements and combustion experiments performed. Rheology of fuels will be determined and fluid properties of candidate formulations evaluated. During Phase II the scaled-up synthesis of preferred hybrid fuels will be performed and more extensive testing of properties (rheological and combustion) of preferred formulations conducted.

Title:Soluble Nano-Catalysts for High Performance Fuels
Abstract:Currently there is a strong interest in developing new weapons systems that increase the vehicle's speed and range. Several types of advanced propulsion systems could be considered for this purpose, including high-speed turbines, ramjets, scramjet, and pulse detonation engines (PDE). However, maintaining stable fuel combustion in these high performance engines is a significant challenge. At the highest air velocities, the ignition of the fuel and air mixture must occur within milliseconds. Although increasing the pressure in the combustor inlet reduces ignition delay, the engine cycle is severely penalized. Thus methods to reduce ignition delay are needed. In this Phase I project, TDA Research, Inc. (TDA) proposes to investigate the use of soluble nano-scale combustion catalysts to enhance the ignition characteristics of jet fuel in difficult combustion environments. The presence of a catalyst will allow the combustion reaction and accompanying heat release to begin at a lower temperature, effectively reducing the auto ignition time. We will prepare the nano-scale catalysts, characterize the size of the particles after they are combined with the fuel, and finally measure the effect they have on the rate of combustion. Success in this research could greatly improve the performance of high-speed engines.

Title:Model-Based Adaptation for Performance Assured Control of a High-Speed Supercavitating Torpedo
Abstract:Supercavitation is a state in which a gas cavity substantially encompasses a body immersed in a liquid. The consequence for underwater bodies is that drag over the non-wetted surface is drastically reduced, and this can be exploited to develop rapid reaction defensive weapons for submarines. In addition to propulsion and active flow control requirements to initiate and maintain the supercavity, guidance and control systems are needed to provide the agility for close aboard engagements. An adaptive control design is proposed to assure performance for the inherent nonlinear dynamics of the free surface flow, the interactions between flow, cavity, and afterbody, and the diverse launch conditions and terminal states demanded by the problem. A model-based framework is chosen in which neural network characterizations of the nonlinear dynamics are used in an online control design. Parameter identification and provably stable update laws are then added to adapt the models used for control decision to account for plant uncertainties, and lastly, a composite error control approach is incorporated to adaptively cancel unwanted nonlinearities in the responses. Phase I uses a medium fidelity simulation for controller design and a higher fidelity model for evaluation to further demonstrate the benefits of our adaptive control architecture.

Title:Micro-Hydraulic Pump for Supercavitating Vehicle Control
Abstract:The US Navy has recently become interested in the development of supercavitating vehicles for many missions. High-speed supercavitating vehicles (HSSV) typically travel underwater at speeds above 150 knots in a cavity that covers most of the body, produced by the dynamic action of the fluid, or more commonly, by exhausting ventilation gas over the body. If the vehicle is designed correctly, there is significant drag reduction since only small regions at the nose and afterbody contact the water. The small water/body contact however limits the options for controlling the vehicle. Development of highly maneuverable supercavitating vehicles requires small high performance actuation systems. NextGenAero proposes to use its expertise in adaptive structures and micro actuation to design a fin control system to command both the fin's angle-of-attack and sweep in a compact form that can fit at its base. The compact control system will use a piezehydraulic pump, which NextGen has been using, and further developing, for other actuation programs, and has demonstrated superior power density. The research team will also include the Penn State Applied Research Lab, which is responsible for the control subsystem of the Supercavitating Test Bed program, providing supercavitating vehicle requirement expertise and testing capabilities.

Title:Probabilistic Error Estimation In Model-Based Predictions
Abstract:A software product will be developed that will enhance common engineering analysis tools with a probabilistic capability. This capability will involve the probabilistic quantification and management of confidence in the model-based predictions. The quantification of the confidence will be achieved by relying on Polynomial Chaos representations of stochastic variables and fields. This will permit the development of the software product as a library that integrates, with the least amount of intrusion, with existing software packages. In addition to characterizing the probabilistic content of the predictions, this formulation also permits the computation of the sensitivity of the probabilistic statements regarding the predictions with respect to probabilistic statements on the random data. This information can be used either to identify those probabilistic statements that are consistent with available information, or to design data acquisition efforts aimed at achieving a target confidence in the predictions,

Title:Probabilistic Error Estimation In Model-Based Predictions
Abstract:Modern ship designs can only be successful if the ship can survive in a hostile environment. External threats for a ship can originate from underwater detonations, anti-ship missiles, and even low tech weapons like in the terrorist attack of USS Cole. These threats become even more important as the focal point for naval operations has shifted towards littoral areas, where ships are exposed to a higher risk. Current analysis methods do not provide high level of confidence and large structural design safety factors are used. Thus, ships are heavier and more expensive to construct and maintain than may actually be required. Models that quantify the level of confidence are required in order to provide meaningful and reliable information during the ship design stage. The proposed project will develop a system for probabilistic Error Estimation in model based predictions. It will utilize commercially available non-linear codes for shock analysis (LS-DYNA, ABAQUS, LS-DYNA/USA, etc.), a limited amount of test data, the level of uncertainty in model parameters and in the test data. Based on this information it will update the numerical model for improved probabilistic correlation to the test data and it will provide a probabilistic error estimate for the numerical results.

Abstract:ResearchSouth will develop a software product for error estimation and uncertainty analysis of computational mechanics code predictions. We will develop methodologies for at least the following methods: interval analysis, sensitivity derivatives, Monte Carlo methods, moment methods and polynomial chaos. An existing and proven fluid-structure interaction code will be used to model many design points by running cases in parallel on information grids. The design points will be set up automatically by perturbation from nominal conditions. This large database will be reduced through an uncertainty analysis using both probabilistic and deterministic uncertainty methods. We will compute test cases for validation including a fluid-structure interaction case on a generic ship hull and compute error bands on the computations. Based on the computational results, the most promising methodologies will be selected for implementation. The Phase I plan is to continue our on-going literature survey on recent developments in stochastic finite elements, formulate the deterministic and probabilistic models for uncertainty, code a new module to implement these formulations, use our existing fluid-structure interaction software for testing the algorithms, validate the solutions, reach conclusions on feasibility and accuracy, formulate a plan for implementing them into commercial codes, and document the Phase I project.

At the conclusion of a successful Phase I effort we will provide the Navy with a design and laboratory demonstration system with associated sensors and sampling times that are synchronized within the time stamp the defined time stamp resolution. Specifically, 3 Phoenix will work with Navy to identify candidate systems that will benefit from synchronous sampling and fusion; demonstrate real time data fusion and time synchronous sampling; and, provide a detailed technical and performance tradeoff.

Abstract:Los Gatos Research, Inc.

The prototype will be rack mountable for use on research aircraft or ships, compact, robust, and capable of simultaneously measuring aerosol extinction and scattering coefficients to 0.1 Mm-1 at three wavelengths with a 1 second sampling rate. This highly innovative and unique instrument, based on cavity-enhanced laser spectroscopy, will operate autonomously and continuously stream data for storage or downlink. By significantly increasing the speed, sensitivity, and accuracy of in situ aerosol optical property measurements, this instrument will enhance studies of atmospheric aerosols and provide valuable data critical to the elucidation of aerosol effects on the radiative balance of Earth's atmosphere. This instrument will also provide information which will aid in the interpretation of data acquired by existing methods such as lidars, radiometers, and laser scatter probes. Data from this instrument will also be of great use in determining how in situ measurements compare to remote sensing measurements.

Title:Advanced Oil Viscosity Measurement Technique
Abstract:A micro electro mechanical system (MEMS) based sensor is proposed for measuring the viscosity and density of oil. Sensor attributes, which include small sample size (<1ul), fast readout (seconds), and low power consumption (<1 Watt), make it attractive for portable applications, online deployment, and applications that are sensitive to particle generation. Preliminary lab data taken with a prototype sensor over temperature using COTS motor oil indicates that the sensor's dynamic range and sensitivity meet the requirements of this application. During Phase I, sensor performance will be assessed with clean and contaminated commercially available samples that simulate field conditions of the sponsor's application. The goals of the program are to achieve 1% accuracy over a dynamic range of at least 90-308 cSt within a measurement time of less than 1 minute.

Title:Low Cost, Integrated Viscosity Measurement System for the Portable Fluid Analyzer and Total Oil Monitoring System
Abstract:Foster-Miller, Inc. proposes to develop and deliver a viscosity sensing capability for the Portable Fluid Analyzer (PFA) and Total Oil Monitoring System (TOMS) which utilizes both existing infrared spectra gathered by these instruments and flow hardware to report an accurate measurement of viscosity in diesel and other lubes. The proposed system will have the capability of measuring viscosity over a wide range of values (1-500 cSt at 40oC) in a variety of lubes at very low flow rates. As the developer of the infrared spectrometer used by the TOMS and PFA systems and derived oil condition algorithms, Foster-Miller is uniquely poised to deliver an infrared-based viscosity prediction system to the US Navy for these and related applications. The Phase I program will evaluate the infrared spectra and viscosity of a set of calibrated and field-degraded MIL-L-9000 lubes from which viscosity prediction based on the infrared spectra will be produced and verified through blind testing. In addition, a direct microfluidic-based viscosity measurement which utilizes existing flow sensing hardware contained within the infrared spectrometer will be developed and evaluated. Phase II will incorporate the system optimized during the initial effort into the existing PFA and TOMS systems for US Navy validation. (P-040121)

Title:Advanced Infrared Oil Viscometer
Abstract:To address U.S. Navy needs for advanced oil viscosity monitoring instrumentation based on infrared spectroscopy and/or other optical means, Physical Optics Corporation (POC) proposes to develop a new Infrared Viscometer (INVISCO) system. This proposed system integrates a multiband infrared spectral module with a neural network processor to infer engine oil viscosity. INVISCO can directly and accurately measure diesel engine lubricant viscosity from infrared measurements. It also points to the causes of viscosity changes. Fast processing allows rapid sampling of viscosity, making it suitable for in-line fluid monitoring. In Phase I, POC will assemble a breadboard INVISCO system and conduct preliminary experiments to prove the advantages of the INVISCO technology by comparison with commercially available viscosity measurement instrumentation. In Phase II, POC will assemble an advanced INVISCO prototype based on the specifications of two infrared measurement instruments provided by the Navy. The advanced prototype will be designed to be integrated into existing optical instruments such as the Portable Fluid Analyzer (PFA) to meet the needs of the U.S. Navy. INVISCO technology will transition into the commercial sector for integration into current and future DoD fluid analysis systems.

Title:Littoral Geoacoustic Surveys Using an Adaptive Network of Gliders
Abstract:Acoustic sensor systems are the backbone of both anti-submarine (ASW) and mine-countermeasure (MCM) systems. Inadequate knowledge of the acoustic environment, especially in denied areas, results from a lack of survey equipment, funding, and access to areas of tactical interest. Moreover, the acoustic environment can change substantially depending on conditions such as sound speed, water depth, and surface conditions. Predictability of specific acoustic conditions has proven difficult. Only the roughest estimates, by definition incorrect, are available to today's warfighter. The ability to measure the acoustic environment directly is essential. Of the many measurements possible the most useful to the warfighter are the sound velocity profile, bottom loss, and bottom reverberation. This proposal will design a system for determining bottom loss and bottom reverberation characteristics with an active acoustic source and distributed receivers. The proposed system will be suitable for deployment on autonomous underwater gliders, allowing investigation of denied areas. Multiple gliders may be driven by a detected "source" to adaptively move and reconfigure to achieve array gain as required.

Title:Magnetoelectric Sensors for Detection and Mapping Applications with UUVs
Abstract:In support of the Navy's expanding role for UUVs, NanoSonic will demonstrate a unique, magnetoelectric sensor and its integration with an ONR sponsored UUV. The local magnetic field within the undersea environment holds particular interest to the Navy in multiple applications including unexploded ordinance detection, navigation, and detection and tracking of undersea vehicle threats. In recognition of this need, NanoSonic will assist the development of an ONR UUV project by integrating a sensor package designed for magnetic field detection. NanoSonic proposes a small, room temperature, lightweight, low power and inexpensive magnetic field detection system; a three-axis version will provide direction finding ability and allow effective signal processing and background interference rejection. The current device has a higher sensitivity than common magnetometers and is expected to exceed that of SQUIDs. NanoSonic will work with university researchers who have specific experience with small, inexpensive UUVs and their cooperative networks. In addition to working with our university partner, NanoSonic will work with its transition partner, a major defense contractor for underwater systems. The NanoSonic PI has direct experience in the defense industry on sensor, propagation and cooperative identification problems through unclassified and classified efforts.

Title:Surf Zone (SZ) Mapping and Sensor System
Abstract:The importance of Very Shallow Water (VSW) and the Surf Zone (SZ), VSW/SZ, for littoral operations is well known. Both ocean dynamic conditions and bathymetry may vary significantly in space and time. The harsh SZ environment (mainly due to currents, waves, and surf) makes data collection using in-situ sensors or Autonomous Underwater Vehicles (AUVs) difficult especially for a mobile sensor system to be used where needed. An innovative bottom drifting sensor system is proposed to measure oceanographic variables, including bathymetry, in 3-D space and time in the SZ and extending into the VSW region. A drifter would be relatively invulnerable to breaking waves and would utilize near bottom currents to provide drifter locomotion without using its own power. While bottom drifters would be miniaturized, they could be large enough to accommodate several sensors to measure bathymetry, waves, surf, and other data. Several deployed drifters would constitute a mobile SZ measurement and mapping system. Techniques will be investigated and developed to track drifters recognizing SZ acoustic limitations. Because of SZ currents (e.g. undertow and rip currents), drifters will generally be transported outside of the SZ where, particularly for scientific experiments, they could return to the surface for reuse.

Title:Integrated Inherent Optical Property Sensor for AUVs
Abstract:The objective of the proposed work is to design, fabricate, and test an AUV-compatible sensor for determining the fundamental Inherent Optical Properties (IOPs) of seawater: beam attenuation (c), total scattering (b), total absorption (a), and backscattering (bb). The work builds on our recent SBIR success in developing an AUV-compatible beam attenuation meter and backscattering sensor, which have now been deployed on multiple occasions on several AUVs, including a Slocum glider. With these recent technological advances in hand, the primary new innovation is a methodology for determining total scattering with a low-power/volume/cost sensor. Since c = a + b, and c and b will both be directly measured, a can be derived by difference. These techniques will thus allow simultaneous measurement of the fundamental IOP suite (c, b, a, and bb) with a hydrodynamic sensor only several centimeters in length.

Title:Laser Plate Butt Welding Project
Abstract:The proposed project addresses the Navy's need to reduce shipbuilding costs and improve delivery schedules by developing equipment and methods to dramatically improve the welding of plate panel butt joints. Comprising the outer hull, decks, and bulkheads of ships, these panels remain one of the highest-cost welding and inspection operations in shipbuilding. In addition to welding and inspection costs, traditional welding processes cause significant warpage, requiring expensive and time consuming downstream rework, in straightening and/or adding of fillers and levelers. Fillers provide no structural benefit, but increase vessel weight and compromise stability. This proposed SBIR project will demonstrate that using hybrid Laser-assisted Gas Metal Arc Welding (LGMAW), weld joints can be made in less time, at higher quality, and with less distortion than with traditional methods. In addition, plate preparation and handling costs will be reduced, since the hybrid-LGMAW process can work with plates directly from the cutting process, and can be welded from one side. The hybrid-LGMAW process will reduce panel line cycle times, reduce downstream rework, while at the same time providing improved base metal properties by virtue of its lower heat input.

Abstract:The objective of this proposal is to build a cost-effective and flexible paint planning and estimating system to enhance the surface coating processes of U.S. shipyards. Utilizing parts and product information from the shipyards product model environment, the proposed paint planning system will calculate surface areas of parts and assemblies that require painting. Information management functions will provide the appropriate information for paint shop bidding, estimating, and procurement processes. This proposal will build on Atlantec's TopgallantT suite of interoperability products and the architecture and data models developed in the NSRP ISE projects. The goals of our proposal are to provide advanced paint planning and estimating functions, and to streamline and optimize the surface coating business processes through information management functions. Advanced paint planning processes have the potential to improve the productivity and execution of surface coating operation in shipbuilding significantly.

Title:On-Demand Release, Structural Adhesives for Rapid Assembly/Disassembly in Shipbuilding Operations
Abstract:Advanced high-strength epoxy adhesives are proposed for ship building operations. These adhesives possess the remarkable ability of rapidly releasing when treated with a low power current (d.c.). The adhesives can be used to make temporary high strength attachments to both metal and composite substrates during the performance of construction tasks. These attachments can then be removed with minimal time and effort, allowing the bonded substrates to be easily restored to a pristine condition. When used to form permanent bonds during ship construction, this high added value technology permits structures to be rapidly disassembled for repair and refurbishment operations. This technology will provide substantial time and cost savings in virtually all areas of ship construction. These savings will multiply with the increasing use of composites in ship construction. During the proposed research, personnel from Bath Iron Works will use electrically releasing adhesives in the performance of two non-safety critical shipbuilding tasks. This demonstration will permit development of application techniques and guidelines for use of the adhesive in the shipbuilding environment and will promote the expansion of this technology to the broader range of shipbuilding activities

Abstract:This project will evaluate the feasibility of developing software to address the following problems: (1) analysis, simulation, design and planning of surface preparation and coating of ships, (2) integrating statistical accuracy and distortion prediction into the design and planning process, (3) automatic extraction of weld planning data from CAD databases, and (4) integration of automatic planning and design tools with the popular ShipConstructor package. The tools are intended to generate accurate coating material and labor estimates and will interface with existing systems for estimating, material ordering, and scheduling. An existing automatic planning and design for producability tool, SmartPlan-ShipsT, will be used as the framework for development of this new software capability. To address the needs of a number of U.S. shipyards, an interface will be designed to allow the SmartPlan-ShipsT automatic design and planning software tools to interoperate with the ShipConstructor software package. A working prototype will be developed in Phase I for piping.

Title:Laser Ultrasonic Shipbuilding Weld Inspection and Monitoring System (Laser SWIMS)
Abstract:This Small Business Innovation Research Phase I project will determine the feasibility of using laser ultrasonics as a cost-effective technique for in-process inspection of automated welds used in the shipbuilding industry. Laser ultrasonics is a technique for performing ultrasonic inspection using a pulsed laser to generate the ultrasound and a separate cw laser interferometer to detect the ultrasound at the point of interrogation. Laser ultrasonics offers several attractive features for the automated inspection of welds: (1) its remote nature allows the interrogation of hot surfaces in the production environment, (2) the capability of scanning allows the gathering of data at a high rate, (3) advanced, compensated receivers allows the interrogation of rough surfaces moving at high speeds and (4) its high bandwidth provides significant information for signal processing and interpretation. Our approach during Phase I will be to optimize the laser generation and detection process, determine the best beam configuration and develop robust signal processing techniques. We will then build a laboratory breadboard for testing of samples provided by end users. Lasson will team with a shipbuilding company and a supplier of welded components, who will provide guidance on user needs and supply samples for testing. In Phase II a prototype field inspection system will be developed and tested at an end user site.

Title:Development of Double-sided Arc Welding for Shipbuilding
Abstract:Double-sided arc welding is a novel process recently developed at the University of Kentucky. The current procedure for ship hull joining involves bevel preparation, root pass welding, second side joint preparation, multiple fill passes, associated equipment set-up for each pass, cleaning following each pass,and costly/time-consuming correction of workpiece distortion.The double-sided arc welding process has the potential to reduce the current procedure to a single pass for typical 1/2" ship hulls while eliminating bevel preparation (both sides).Hull plate distortion is minimized by eliminating multiple passes and the deep narrow penetration typical of the double-sided process, with its symmetrical heating mechanism and resultant narrow symmetrical weld bead. However,to allow use in a shipyard environment,the current laboratory version requires further development and several innovations. This SBIR Phase 1 project focuses on proving the feasibility of several proposed innovations which are critical to improving the suitability of DSAW for a shipyard environment.These include the concept of using a single power supply; using feedback control to improve the process's robustness with respect to variations in manufacturing conditions such as fit-up gap;using back-side modules to simplify system setup; and on finding more economic filler metals.

Title:Remote Thermal Imaging for Reliable Deception Detection
Abstract:Thermal imaging of the face and head for the purpose of deception detection has shown significant promise in recent studies. This technique could be used to enhance polygraph examinations and, because it is noninvasive, could also potentially be used for mass screening at critical security checkpoints. The primary technical obstacles that must be overcome in order to realize a system suitable for these applications are: (1) achievement of adequate thermal resolution to detect the signals of interest, (2) localization of the appropriate target area at a distance, and (3) realization of automated signal processing software. Barron Associates, Inc. (BAI) has teamed with Mayo Clinic to propose a research program that will enhance the understanding of the physiology of deception and will produce a system targeted for employment in mass screening applications. The Mayo Clinic will perform clinical experiments using its system for thermal imaging of the face (STIF) to capture the transient thermal responses associated with deception. BAI will implement invariant feature extraction algorithms, apply these algorithms to the captured thermal image sequences, and use these invariant features as input to its GNOSIS neural network synthesis software to synthesize automated classification networks that can be used for real-time deception detection.

Title:A Novel Integrated Deception Recognition System Using Thermal and 3D/2D Imaging Analysis
Abstract:Genex Technologies, Inc, in collaboration with Walter Reed Army Institute of Research (WRAIR) and University of Maryland (College Park), proposes herein an innovative three-dimensional (3D) thermal imaging system that is able to acquire multi-modality facial/head images and perform image analysis for the detection and recognition of thermal brain activity emanating from the skull over particular cortical regions related to concealed intent of the subjects. The unique design of our 3D thermal camera allows it to acquire co-registered dynamic facial images with three independent imaging modalities: 2D texture, 3D geometry, and thermal distribution. We therefore can obtain high-resolution "geo-thermal" images (containing co-registered 3 imaging modalities) in real-time. This unprecedented real-time multi-modality imaging sensing capability provides a rich set of information that could lead to a reliable, practical, and remotely operational sensor system for concealed intend detection and identification.

Title:Thermal Imaging of the Head for the Sensing and Identification of Concealed Intent
Abstract:There are immediate needs for fast and cost-effective detection of concealed information or intent in homeline security applications such as border control, critical facility access. Unfortunately, traditional polygraph is not suited for this type of fast screening applications because it requires invasive contacts and extra time to administer. To meet today demand, new modalities have to be studied and examined for their potential efficacy in deception intent detection. Preliminary experiments showed that infrared image of face, or facial thermography, was a solution with promise. However, systematic studies are needed before it can be utilized in real applications. In this phase I project, we will address facial thermography problem in the following aspects: Guilty Knowledge Test (GKT) model design, data collection and verification, thermal feature selection and automatic recognition algorithm. GKT experiment is designed based on real world, personal experience and knowledge. The thermal data collected are compared and cross-validated against proven modality of brain activities as reflected in the P3 component of EEG in event-related potentials (ERP). The relevant facial thermagraphy features are selected through signal and statistical analysis. These features will be used in a dynamic pattern recognition scheme for fast and effective detection of deceptive intent. It is our objective that through our systematic and scientific research, the end results of this project will answer the following questions: which and how thermal facial features are related to brain activities resulted from deception related events; what is the range and limitation of these features; how effective they are in detecting deception.

Title:Deployable Micro Weather Sensor
Abstract:Real-time meteorological data is becoming ever more critical to military operations. Such data should be available from as many locations around a theater of operation as possible. To that end, there is a need for compact weather sensors that can be quickly deployed by a wide variety of methods, ranging from high-performance aircraft to infantry soldiers. The resulting local weather data will be of use in many ways, such as the planning of sensor and weapon mixes, prediction of sensor performance, personnel preparation for operations, and in predicting the dispersion and lifetime of chemical and biological weapons. A unique micro weather sensor will be developed that is built around a patent-pending anemometer system. This anemometer system offers several very unique features that will not only allow the anemometer to function in environments that would prohibit the function of standard anemometers, but will also allow it to deliver additional meteorological data products. This anemometer is the heart of the proposed system, and Phase I development work will focus extensively on the miniaturization of this technology. The technology is also expected to have substantial commercial potential; the miniaturized form will expand these markets and open new possibilities for the technology.

Title:Deployable Micro Weather Sensor
Abstract:In order to develop a realistic common operating environment for both mission planning and operations, timely weather information is critical. Weather is a critical factor to mission success in our high tech era where the warfighter relies upon ever increasingly sensitive optical systems. Real time knowledge of the 3-D atmospheric cube in the battle space can lead to safer, more efficient operations. Numerical Weather Prediction models used to support in-theater operations require higher resolution meteorological observations to set their initial conditions. The more frequently and accurately these initial conditions can be acquired the more accurate forecasts will become. We describe a Deployable Micro Weather Station, that acquires basic surface weather parameters and feeds data into forecast models via satellite data links. It is designed for mission flexibility and can be hand emplaced or air-dropped. In the latter application, 4D weather data are acquired on the way down, enhancing its capabilities. Our approach leverages proven commercial off the shelf sensor and communications technologies as much as possible in order to minimize risk and ensure long term component availability at the lowest cost.

Title:Dynamically Configurable Antenna
Abstract:Current shipboard antennas create a virtual "antenna farm" on the decks and superstructures of most Navy ships. A flexible solution is required to reduce the number of antennas, integrate them into the hull form and ultimately produce a single antenna capable of operations over needed frequency bands. To this end, an antenna capable of operation across multiple bands dynamically reconfigurable in bandwidth, beamwidth, gain and directionality that can be designed into any type shape or style would be highly desirable. Malibu Research's plasma antenna concepts may be a potential solution to the development of a new class of antenna architectures with the inherent features of: (a) reduced RCS, (b) flexibility, (c) "reconfigurability on the fly," and (e) conformability with the added feature of EMI/EMC mitigation. In addition they can be made low cost and light weight.

Title:RF Solution to Narrow In-Band Interference in UHF SATCOM Channels
Abstract:UHF MILSATCOM channel availability is limited by sporadic narrowband interference. When frequency separation between the interferer and signal-of-interest is insufficient, use of conventional fixed-frequency filtering will result in unacceptable distortion to the signal-of-interest. In this Phase I project, GIRD Systems proposes novel algorithms and approaches for detection and excision of interference from an in-channel desired signal. The proposed algorithms will be analyzed and evaluated with respect to customer-identified typical channel conditions. The algorithms demonstrating the greatest interference mitigation potential will be identified and extended to the multi-interferer, multi-channel case. Finally, preliminary hardware design will be performed. In Phase II, GIRD Systems will develop and deliver to the Navy prototype interference excision hardware.

Title:Interference Rejecting Receiver for SATCOM Systems (IRRSS)
Abstract:There are many papers and articles written describing receiver design methods for many radios using closely spaced channels and large differences in signal levels. The receiver design is usually centered around filtering out adjacent signals and having a `linear' enough design so that Intermodulation Distortion (IMD) products don't degrade the receiver performance. Neither of these methods addresses interference in the desired receive channel, and if that is the case then usually the channel is avoided or categorized as a degraded channel. A problem with this approach is that if the interference is not constant, or comes and goes, then a potentially usable channel is labeled unusable and the overall system performance is compromised. The problem only becomes worse when there are potentially multiple signals that are in band.

These practices have allowed for frequent hardware technology insertions while maintaining full reuse of a single software baseline across platforms. Electronic Attack (EA) systems being fielded today have not yet adopted these architectural principals. Instead, they are characterized by long-lead, purpose-built hardware and software. The objectives of this Command and Control Communications Systems Denial proposal are formulate an EA appliqu design that fits within these emerging ES systems, and to formulate the weapon control mechanisms needed to allow complex target signal activity to be observed and attacked with precision. This last step is key to giving the IO weapon operator the ability to achieve specific effects ranging from denial of an entire class of activity to deception of a specific entity during a specific phase of military activity.

Title:Command and Control Communications System Denial
Abstract:Disrupting enemy command and control networks is a powerful capability for protecting friendly forces during offensive or defensive operations. Tactical military deception of the enemy's abilty to detect, locate and engage friendly forces and denying this information to the command and control structure can allow for rapid defeat of hostile forces. The enemy exploits the RF spectrum in the form of radio communications and radar to form situational awareness accross the command and control network and to engage hostile targets. This proposal describes the development of an electronic Military Deception (MILDEC) capability that can potentially provide ground based or airborne friendly forces with the capability to disrupt the abilty to detect, locate and engage these forces. The use of high speed RF memory, signal processing and special purpose algorithms can replace more traditional means of deceptions and self protection.

Title:Command and Control Communications System Denial
Abstract:Commercial communications methods, particularly direct-to-user satellite communications and terrestrial wireless networks, offer hostile forces and terrorist organizations a simple, inexpensive, and reliable means to establish tactical command and control communications links. In this paper, we propose to capitalize on our work in special signal communications intercept to study the prominent commercial services for vulnerabilities, and analyze the present shipboard RF configurations to suggest a series of techniques that could be used for denial, deception, and interception of enemy command and control communications.

Title:Radio Room RF Integrated Switching Matrix Based on Second-Generation RF MEMS
Abstract:MEMS technology has the potential to provide RF switching matrices of extremely compact size, low power, and improved reliability. The main challenge lies in improving the power handling of MEMS switches. MicroAssembly Technologies has demonstrated experimental switches at up to 3,200W. Currently, the company is developing a high-reliability switch, which may enable more immediate application at 50W or higher.

Title:Breatheable Ablator Concept for Extended Flight/Maneuvering Navy Strategic Reentry Bodies
Abstract:The proposed program will develop a breathable ablator concept for application to Navy extended flight or maneuverable reentry vehicles. The breathable ablator concept will consist of a high-density, carbon-carbon outer shell over a charring ablator. This material configuration provides a greater resistance to ablation over longer flight times, where conventional materials would typically burn through, while utilizing the known insulative performance of charring ablators. A stack-up configuration of these materials will be developed in this program to allow the charring ablator to breathe during reentry through the carbon-carbon shell. A Test specimen configuration will be designed to integrate with the current Navy arc testing program, as well as a series of test conditions to evaluate these extended flight scenarios. Finally, Phase I will produce a plan for Phase II that will evaluate the thermomechanical properties of these breathable ablator materials and develop additional concepts to verify performance levels.

Title:Development of Nuclear Event Detection and Circumvention Controller Technology
Abstract:In this proposal we discuss several potential approaches to solutions of the current problems associated with transient gamma radiation circumvention in US Navy electronic systems. AET, Inc. proposes a comprehensive and cost-effective solution to the nuclear event circumvention problem, with wide application in US Navy strategic systems. Three options will be considered as solutions to the radiation circumvention problem. The first approach includes a radiation detector and a circumvention chip that controls the circumvention sequence for the entire system. The second approach provides each integrated circuit (IC) with an individual circumvention chip with onboard radiation detector and control electronics. The third approach integrates a radiation detector and control electronics on each IC chip. AET, Inc. engineers will develop the technology and will employ consultants and design/fabrication capabilities as needed. AET, Inc. is uniquely qualified to perform this work because of the long experience that its engineers and consultants have in radiation effects on integrated circuits. In addition, the AET, Inc. team has strong experience in modeling and design of integrated circuits for military applications. The AET, Inc. engineers as well as all of its consultants presently have SECRET security clearances.

Title:Ultra Fast Nuclear Event Detection and Circumvention System
Abstract:Since modern microelectronics are capable of responding in times comparable to gamma pulse risetimes, it is critical to have circumvention techniques that offer protection against the upsets in the same time frames. In the proposed effort our team, Nu-Trek, Titan/Jaycor, and Space Micro, will couple Nu-Trek's ultra fast GaAs Photoconductive detector (PCD) technology (< 30 ps response time already demonstrated) with Titan/Jaycor's System Hardening Upset Recovery (SHUR) technology for a sub-nanosecond nuclear event detector and circumvention system, UF-SHUR. Additional features include false-write protection, prompt immune signal pass-through, hardened clock generation circuitry, multiple fault masking, off-line timer, and hardened recall registers. Engagement levels will be adjustable between E6-E10 rad(Si)/s. UF-SHUR will also significantly improve response time to protect against upsets and faults. In Phase II the technology will be applied to a specific Navy system and demonstrated. An Ultra Fast Nuclear Event Detector (UF-NED) will also be spun off as a commercial product. SHUR is a macro cell library sponsored by DTRA available to all government contractors for use in their designs and UF-SHUR will be offered as an upgrade to SHUR.

Title:Advanced Shipboard Electrical Control and Monitoring
Abstract:Examine the electrical power system of the USS JOHN F. KENNEDY (CV-67) and identify ways to reduce power demand. We will investigate adapting some proven land-based technologies to the warship environment, as well as some bleeding-edge initiatives, including capacitors to correct Power Factor, Variable Frequency Drives to reduce power demand by operating selected motors at slower speed when possible, and Smart Motor Controllers to reduce transient peak startup demand on selected motors. We shall investigate Demand Management Systems to continuously monitor sources and demands and mitigate the severity of cascading electrical system casualties by enacting priority load-shedding. Perhaps most innovatively, we shall investigate the potential energy savings to be obtained through the implementation of Intelligent Agents, a network of discrete digital sensor/actuators which constitute a distributed artificial intelligence capability, in their capacity to monitor, manage, and optimize the performance of a single distributed ship system. We intend to apply for the SBIR Fast Track. In the Phase I Option effort, we shall investigate the potential energy savings from implementing high-efficiency motors, high-efficiency lighting, and extending the Intelligent Agent technology to monitor, manage, and optimize the performance of the system of systems which make up a modern warship.

Title:Electromagnetic Pulse Protection For Distributed, Shipboard Transducer-bus Networks
Abstract:The program objective is to develop and evaluate a distributed shipboard transducer-bus network that is immune to high levels of EMP (electromagnetic pulse). The task involve designing a network that is compatible with open architecture standards such as the IEEE 1451, and existing commercial and military standards. Investigation into network types that are effective for transducer-bus networks and protection technologies. It will also consider the protection of the transducer power supply lines, so that even if an EMP strike does cause a failure in a smart sensor or NCAP that will not affect the remaining sensors on the network or itself. The proposal plans to 1) determine what is known of a quantifiable nature on EMP so that it's potential effects on a protected network can be assessed, 2) evaluate types of protection that can be applied to protect networks, 3) evaluate the types of network implementations, including the IEEE 1451 standards, that can be applied to transducer-bus networks and how available protections can be applied, including protection for wire based networks and inherently EMP proof fiber optic implementations 4) Propose a transducer-bus network such as a fiber optic Ethernet based network, 5) develop the plan a demonstration transducer-bus network.
