Title:Field Chemical Analysis Tool
Abstract:Emission spectroscopy based microdischarge sensors will be adapted to a gas chromatography system for the rapid detection of chemical agents in the field. These systems will be tested to determine optimum column length for seperation and integration time. Microdischarge detectors are rapid, real-time sensors, capable of sub-parts per billion detection of a wide range of atomic and molecular species. They are ideal as gas chromatography detectors due to their small size and low flow requirements, a potetial shortcoming of other available technologies. Additionally, these detectors provide a wealth of spectroscopic data, providing for accurate determination of chemicals present in air, with little chance of false alarms. The entire detection system will be self contained, battery operated, and robust enough for field deployment in its final form. Portable chemical analysis in a hand-held, rugged package will provide a safe effective source of chemical agent detection for protection of the warfighter. A portable, hand held, hazardous chemical sensor will also be applicable for hazmat and fire department use, as well as for the screening of mail, luggage, and security monitoring of buildings. Additionally, the technology developed with this project will be applicable to any situation where size and portability requrements are placed on a chemical analysis tool, suchas in environmental survey applications.

Title:Field Portable GC-MS
Abstract:The instrument of choice for identifying low-level amounts of CW agents and other volatile, highly toxic substances is gas chromatography - mass spectrometry (GC-MS). This analytical tool has the sensitivity required for performing such low-level analyses, and the ability to provide irrefutable confirmation of the identity of a volatile or semi-volatile substance, including CW agents. However, commercially available GC-MS instruments that are rugged enough to withstand the extreme conditions of outdoor environments and are able to provide results in a timely manner cannot also provide analytical results of laboratory quality. However, emerging technological improvements in gas chromatography (i.e. "Fast" GC) have greatly reduced analysis time from tens of minutes to 1 or 2 minutes. These improvements include redesign of the oven heaters and the vacuum system. By utilizing both of these new technologies in combination with reliable, commercially available mass spectrometers, it is now possible to construct a portable GC-MS capable of being transported by one person, performing analyses in a matter of minutes, and providing reliable analytical results of laboratory quality. Constellation Technology Corporation (Constellation) proposes the incorporation of these technologies into an already existing portable GC-MS produced and sold exclusively by Constellation as a commercial instrument (CT-1128 Portable GC-MS). The existing Constellation field-portable CT-1128 GC-MS unit weighs 75 pounds and provides reliable data of laboratory quality in approximately 17 minutes. The unit is fully capable of detecting a wide variety of volatile and semi-volatile compounds including, but not limited to, CW agents and their surrogates, controlled substances (i.e. illicit drugs), explosives, and industry-related solvents and chemicals. In addition, the CT-1128 GC-MS is fully compatible with SPME syringes. This research will reduce the weight by 25% and the analysis time by 80%. This will make the field portable GC-MS truly useful for performing on-site analyses for various law enforcement agencies, National Guard, first responders, and the military.

Title:Field Chemical Analysis Tool
Abstract:CyTerra Corporation proposes the development of a new Field Chemical Analysis Tool (FCAT) to meet the increasing chemical analysis needs of a sophisticated and mobile US military force. The key Phase I task will be the development of a re-circulating air oven that will provide temperature programming for GC columns in an oven fabricated from commodity items for low cost. Any commercially available GC column up to a 30-meters in length will be accommodated by the proposed oven design. The overall system is expected to consume 750 watts, weigh 35 lbs and occupy 0.15-m3 volume. The anticipated analysis time is less than 90 seconds, and the overall analytical cycle time (i.e., analysis time + cool-down time) will be less than 10 minutes. This novel low thermal mass heating technology provides the basis for a modular approach to field chemical analysis. In Phase I, a Re-Circ heating oven breadboard will be interfaced to existing SPME and MS detection equipment to validate the FCAT design concept. It is anticipated that FCAT will capable of providing laboratory quality chemical analyses in the field. The overall goal of the proposed project is to develop a modular FCAT with configurable sample introduction and detection modules. Taking advantage of years of experience developing field instruments based on fast gas chromatography (GC), CyTerra Corporation proposes the development of a modular FCAT. The anticipated benefits include meeting the field industrial hygiene analysis needs of a mobile military with a sophisticated chemical analysis tool that has configurable interfaces for both sample introduction and detection. The immediate benefits are providing a compact, low power, high performance chemical analyzer in a package suitable to a mobile, fast-deployed military force. A modular instrument design will be the cornerstone of the FCAT such that field operation is simple, field maintenance is infrequent, and set-up time of 15 minutes. Since the low thermal mass oven design is universal for all commercial GC columns and the instrument design is modular, there is the potential to meet many environmental, industrial hygiene and national security chemical analysis needs such as water and air quality, explosives, drugs of abuse or chemical warfare agents. Additionally, since the oven will be fabricated from existing commodity products, the manufacturing cost will be low. The FCAT system controller will be based on existing powerful computer technology making it a versatile standalone tool.

Title:Field Chemical Analysis Tool
Abstract:The purpose of this Phase I effort is to demonstrate the feasibility of using an integrated field portable instrument for field chemical analysis. Currently, no fieldable chemical analysis technology is available that can provide real-time monitoring of hazardous compounds in complex samples such as ambient air. The proposed field-portable integrated SPME sampling, flash GC, miniature mass spectrometer (MMS) will meet this operational need. The performance and capabilities of the MMS instrument will be best in class by providing a level of selectivity that is unmatched by current fieldable mass spectrometers or ion mobility spectrometers. Development of this system will transform traditional sample-to-lab analysis to lab-to-sample analysis. This concept will provide high-end chemical analysis in the field with the potential to save lives and provide a competitive advantage to U.S. armed forces. The performance specifications of this instrument will be demonstrated in Phase I and a full prototype will be developed during Phase II. The instrument that will be developed as part of this Phase I effort will be able to detect chemical warfare agents in the field, but will also find use in Homeland Security, customs monitoring, airport screening, and environmental protection.

Title:Field Portable Flash Collection Flash SPME-Flash GC-IMS
Abstract:Implant Sciences Corporation (ISC) proposes to create a Field Portable Flash Collection Flash SPME-Flash GC-IMS unit for the detection of trace chemicals in samples or the environment. The unit will incorporate a cyclonic gas collection nozzle with an integrated high-intensity flash lamp, which will allow for the sampling of volatiles and semi-volatiles from as far as 5 inches away from the surface of interest without significant loss of analytes to the surrounding air. The gases collected by the cyclone nozzle will pass over a standard SPME fiber for a predetermined length of time, after which the fiber will be flash desorbed into a flash GC column. The chemical species exiting the flash GC will be detected by a modified, portable IMS unit developed at ISC which has high resolution, unusually high sensitivity, and has a demonstrated capability of detecting ambient explosive vapors at parts-per-trillion concentration levels. Detection of a wide variety of trace chemicals of interest in the areas of national defense; environmental assessment; water quality management; airline, postal, shipping and general security; and the prevention of, or quick response to, terrorist attacks involving the use of chemical and biological weapons or poisons.

Title:GC/TOFMS Field Chemical Analyzer
Abstract:In this SBIR Phase I project we will demonstrate a field-portable chemical analyzer based on a SPME interface to a compact GC/MS system. Syagen has pioneered photoionization mass spectrometry (PI MS) and will use its field-portable PI/QitTof MS as the baseline detector. This system will be modified to meet the requirements of this topic in the following ways: (1) redesigning inlet to accommodate SPME samples, (2) integrating and optimizing a flash GC subassembly, (3) constructing and implementing a dual PI/EI source, (4) developing SPME and direct sampling strategies. The end result of this research will be a feasibility demonstration and definition of a system that will significantly outperform competitive systems with regard to multiple compound detection, sensitivity, speed, and accuracy. Automated field portable detection systems with benchtop performance will have numerous applications, particularly if it combines chemical weapons, drugs, and other illicit chemical detection capabilities. Specific applications include: (1) rapid response alarm monitor for terrorist acts, (2) force protection, (3) preventive medicine, (4) treaty compliance monitoring, (5) general environmental monitoring.

Title:Extending the Life of Biosensors with Dendrimers
Abstract:Echo Technologies, Inc. (ETI) is developing optical biosensors for detection and discrimination of biological warfare agents. The sensors incorporate molecular recognition and fluorescent reporter molecules that are chosen to uniquely detect classes of biological material. Degradation of the fluorescent reporter molecules is one of the important parameters affecting sensor stability and lifetime. Dendrimers are highly branched polymers containing well-defined internal cavities that can therefore function as "host" molecules for one or more "guest" molecules. Preliminary studies suggest that dendrimers could be incorporated to improve sensor properties such as operational or storage lifetime. Echo Technologies proposes to utilize the unique dendrimer characteristics to greatly improve the stability, and operational and storage lifetime of bacterial biosensors. In Phase I the protocols will be developed to incorporate dendrimers of different size and bearing different functional groups into the sensor membrane. The sensors will be tested using aerosolized and waterborne bacterial challenges to demonstrate enhanced performance. In Phase I ETI will team with Michigan Molecular Institute (MMI), a recognized leader in the development and characterization of new dendrimer materials. In Phase II the dendrimer-enhanced biosensors will be more fully characterized and the approach will be extended to biosensors for other Biological Warfare Agents. The proposed use of new dendrimer materials to improve the performance of sensors to detect BWA's will greatly broaden the potential applications for these sensors. The resulting sensors systems will be easier to use, lower cost, and will minimize need for user intervention and logistics requirements. Equally significant is that the proposed approach could be a more generally applicable enabling technology for other optical sensors that contain fluorescent reagents or chromophores. This would include sensors based on antibody/antigen recognition or DNA probes on substrates as diverse as fiber optics to disposable colorimetric "tickets".

Title:Dendrimer Coated Long-Period-Grating (LPG) Biosensor
Abstract:The detection of Biological Warfare agents (BW) is typically conducted using antibody-based techniques. DNA aptomer-based Long Period Grating (LPG) sensors provide the specificity to accurately distinguish the target from potential interference that would produce false positive results. Stability is always a main concern for a sensor-based detection platform. Methods to improve sensor stability have focused on using detergents, salts, protein, and pH. Luna proposes to use dendrimer coating based biosensors to improve stability of BW detectors. This new class of highly branched dendritic macromolecules (dendrimers) has gained attention and is being used to increase the solubility of drugs, produce DNA biosensors, and deliver oligonucleotides to cells. Advantages of dendrimers include structural homogeneity, internal porosity, controllable composition, and multiple homogeneous chain ends. The goal of the proposed program is to enhance the aptomer sensor performance by utilizing dendrimers. Through corporate partnerships and government programs, Luna has successfully demonstrated the detection of protein-protein, DNA-DNA, and DNA-protein interactions with the LPG technology. Improvements in biosensor stability will result in systems that will meet requirements that currently are lacking in BW biosensors.

Title:Enhancing Biosensor Life Using Dendrimers
Abstract:Sensera, Inc. proposes to develop novel biological warfare agent optical sensors based on dendrimers and reporter fluorescent dyes. These generic sensors do not have a biological receptor component and are convenient and cheap to assemble. The long lifetime of the proposed sensors will make them ideal for stand alone detection. During Phase 1, Sensera will develop proof-of-concept bacterial and endospore sensors, which will lay the foundation for a small point detector in Phase 2. During Phase 2, we will also construct actual prototype sensor arrays based on the individual sensors developed in Phase 1. Point detectors consisting of these sensor arrays will monitor both air and water for the presence of bacteria and endospores. Sensera's generic optical sensors will have broad potential markets in homeland defense and environmental monitoring. Due to their low cost and long lifetimes, they will be well suited as continuous monitoring devices and for first responder applications in private and public establishments.

Title:Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Coating
Abstract:This Small Business Innovative Research Phase 1 Project provides a novel approach to the development of a single pack and zero-VOC Topcoat for the Marine Corps' land based equipment. The technical approach involves a comparison of two polymer concepts. One utilizes a water borne acrylic, the other a Moisture Cured Urethane (MCU). These coatings represent the latest in the state of the art materials to meet the durability, performance and application demands that are envisioned by the military for the foreseeable future. The resin synthesis will show the feasibility of combining cost effective polymer processing concepts with the use of an inorganic pore filing media. These features represent significant advances in the science of high performance chemical agent resistant coatings. The work will show the feasibility of supplementing the barrier properties with a mechanism to detoxify any CWA agent that comes into contact with the coating's filler material. Such a feature compliments the polymer's cross-linking, as a means to mitigate chemical agent transport through the film. These formulations will be tested using a screening protocol that will identify the polymer and processing approach. This innovative approach to the design of high performance industrial coatings will have a profound impact on a global market that exceeds 5 billion dollars in annual revenues. There is a keen interest in materials that will meet and/or exceed the EPA requirements. This scientific advance will serve the environmental needs of the planet without a compromise in performance properties. Isotron Corporation is in a unique position to advance this science into a viable coating system and is prepared to make these materials available to the world.

Title:Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Coating
Abstract:Current DOD chemical agent resistant coating (CARC) topcoats are required to provide protection to the substrate from the harsh natural/service-imposed operational environments. Current coating systems are solvent-borne two components that require accurate metering of the components. PolyComp Technologies proposes to develop novel one component, zero VOC, ambient curing CARC topcoats that can be applied by conventional methods. Based on polyurethane building blocks, the coating will develop novel morphology upon cure, creating a water impermeable surface that is stable towards CB decontamination fluids, as well as satisfying the requirements as drop-in replacement for current polyurethane coatings The novel coating system can be used as dorp-in replacements for current topcoats in USMC as well as assets in other Services. The coating can also be used in commercial chemical resistant applications such as chemical plants, and protection for Homeland Defense equipments

Title:Development of a Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Coating
Abstract:Spectrum Coating Laboratories, Inc. proposes to develop a single component, zero VOC topcoat using moisture cured resins and diluents and evaluate the feasibility of these materials for use in chemical agent resistant coatings. Spectrum will synthesize the resins and diluents, conduct a pigment compatibility study and characterize the resultant formulations. The proposed materials and formulations are based on Spectrum's chemical agent resistant topcoats currently in use by the USMC. This approach is expected to reduce the cost of development, and expedite the commercialization of this technology. The coating requires no specialized equipment and allows for rapid change of color in the field. This material can be transitioned into Spectrum's Commercial/Industrial coatings and Maintenance/Architectural coatings to produce single component, zero VOC materials. The result is a series of environmentally friendly coatings for use in a wide variety of applications. These coatings will allow both the federal Government and private industries to meet current and future regulations regarding VOC levels for coating facilities.

Title:Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Coating
Abstract:Topcoats on military vehicles must satisfy stringent requirements, including durability in harsh environments. Chemical agent resistant (CARC) coatings must also meet a requirement for low permeation of chemical agents into the coating. Topcoats for these applications were originally two-component (2K) solvent-based polyurethanes, and more recently single-component (1K) solvent-based and 2K waterborne polyurethanes. Single-component coatings have a distinct advantage in ease of use, and in avoiding mixing errors during application that can lead to unacceptable performance in the field. CARC coatings must also meet state and local limits on emission of volatile organic compounds (VOCs). The ideal CARC topcoat would be a single-component coating with zero VOCs. Unfortunately, no such coating is now available. TDA Research, Inc. (TDA) proposes to develop such a zero-VOC 1K CARC topcoat. In Phase I TDA will modify the resin system to achieve satisfactory viscosity for application by spray, brush or roller. We will test film formation and coating performance, and assess formulation stability through accelerated testing. We will evaluate coating resistance to solvents, DS2 decontamination solution, and in the CARC test against live agent. In Phase II we will complete development and testing of the coating, including field tests and long-term durability studies. Single-component polyurethane coatings offer simple application and reliable performance. As environmental standards for VOC emissions on coatings tighten with improvements in technology, zero-VOC systems become more desirable. The system we propose to develop will be used not only by the U.S. military, but will also find wide use in architectural, industrial maintenance and transportation coatings where high chemical and weathering resistance is required, and where application with standard equipment and ambient curing is desired.

Title:Integrated System for AAAV Seals
Abstract:Cornerstone Research Group Inc. (CRG) proposes to design and evaluate the components of an integrated seal design. Advanced Amphibious Assault Vehicles (AAAV) have multiple armor and hatch seals. The primary function of these seals is to ensure watertight integrity and EMI protection. The current sealing system design uses two independent seals to simultaneously achieve the necessary level of EMI protection and watertight integrity. Integration these the two seals into one seal would simplify the seal installation and removal procedure while improving critical physical and materials properties. In addition to the materials and geometric design of the integrated seal, other components of the sealing system should be evaluated. By designing and evaluating the system as a whole, rather than improving each component individually, a new system design can exceed the performance of system that was designed as individual components. The integrated seal system that will be designed and evaluated in this program offers improved EMI protection and watertight integrity in one integrated sealing system. The components of this system, which individually and collectively must meet these stringent properties, will exhibit increased electrical conductivity and increased resistance to environmental exposure. The development of materials with these improved properties, could lead to commercialization of the both the seal system as a whole, or to the commercialization of each component independently.

Title:Lightweight, inexpensive, corrosion inhibiting integral and/or multi-component ElectroMagnetic Interference (EMI) and environmental seals for Advanced
Abstract:The Navy seeks a sealing system that provides air and water tight sealing for egress/ingress sites and other hatches and access panels on the Advanced Amphibious Assault Vehicle. This sealing system must also provide corrosion resistance and the maintenance of EMI shielding between sealed interfaces. METSS proposes to develop an elastomer based sealing system that provides durable air and water tightness by virtue of the compressive properties and chemical resistance of the elastomer seal. EMI shielding will result from making the elastomer suitably conductive to electrically bridge the gap being sealed. Corrosion resistance will come from a combination of the chemical resistance and electrical conductivity of the elastomer. METSS will provide the Navy with design information related to constructing and applying the seal to pertinent interfaces, as well as critical information related to the degree of compressibility required to maintain an air- and water-tight seal. The key element in this proposal is the approach taken to induce electrical conductivity. The proposed approach minimizes the amount conductive additive required to support EMI performance such that the chemical and mechanical resilience properties of the seal material are maintained. A wide variety of commercial and industrial applications require corrosion resistant, air- and water-tight seals. Among these applications are boats and land vehicles. Moreover, EMI shielding seals are required in aircraft, computer housings, and vehicle control systems. Almost all machinery can benefit from improved seals. The combination need for EMI shielding in seals and gaskets is growing as the use of electronically controlled equipment accelerates.

Title:Integrated Multi-Functional Seals for AAAV
Abstract:Triton Systems proposes to develop an integrated multi-functional seal (TIMS) that is lightweight, corrosion resistant, electromagnetic interference (EMI) shielded, chem-bio protective, and environmentally stable for the Advanced Amphibious Assault Vehicle (AAAV). This will be accomplished by combining innovative additives in an elastomeric base (EPDM/Neoprene or like), using Triton's extensive experience in the field of EMI shielding, corrosion protection and nano-technology. For this effort, Triton will adapt its InstaShiel(tm) conductive polymer technology to elastomeric seals for EMI shielding. A metal oxide-conductive polymer (MO-CP) approach will be included for corrosion resistance. Triton's ORMLAS(tm)(Organically Modified Layered Alumino Silicate) nano-technology will be used for chem-bio and barrier protection of the proposed multi-functional seal. In traditional silver and nickel filled silicone gaskets, the metal fillers oxidize over time and demonstrate significant degradation in conducting and EM shielding capabilities. Triton's innovative approach will yield a gasket material that is stable chemically and physically both on the land and sea and offers sustained EM shielding performance. Along with AAAV applications, the proposed technology can be applied to tactical composite shelters. Other opportunities for these EMI shielding gasket materials exist in such applications as shelter systems for military command/control/communications electronics, ground based mobile missile control centers, new and future generation aircraft electronic enclosures, surface and air launched missiles and weapons systems, and ground, sea and air stealth systems.

Title:Multi-component seals for AAAV vehicle
Abstract:Because the AAAV operates within a particularly harsh environment, EMI seals must perform to an exceptional degree of efficiency. The access ports of the AAAV must contain the highest level of EMI protection while demonstrating outstanding sealing and anti-corrosive capabilities. Seal durability and chemical/steam resistance is an important consideration for any material selection in this program. The design concepts Unitech will explore and develop in Phase I and II of this program will continually address these important issues. Corrosion testing and EMI shielding, as well as, seal integrity will be central to all design formats. Although cost and attachment will also be important considerations in Phase I, primary emphases will center on designing the most efficient possible. Phase I efforts will also include a spray system of fabrication that has proved successful in ongoing aerospace program production. This allows layering of materials to tailor the seal's cross-section for optimal performance. Unitech will select several matrix candidates in three material categories noted for their sealing ability and strength. A silicon (RTV) currently approved and used in the F22 program will be specifically examined due to its unique properties demonstrated in 3 year R&D program. It is available commercially and can be post treated to achieve much higher levels of performance than initially advertised. UniShield fill materials (used in commercially available coatings) are already established as some of the highest performance EMI shielding materials ever tested. Listed in the National Security Agency (NSA) databases and currently used by Department of Defense (DOD) for several ongoing applications. We will also investigate several other fill materials that are highly regarded for shielding effectiveness and compatibility. We are confident an exceptional EMI seal system will result in combining these material formulations. It is expected the principle immediate usage for this type technology would be within the Department of Defense. Initial effects would concentrate on making it available for DOD's internal use, with sales to the private sector of secondary importance. Private sector use is anticipated eventually because of the continuing emphases being placed on protection of financial data and propriety industrial trade secrets. Current EMI gasket materials may not provide all the necessary environmental protection in efforts to contain data and protect equipment.

Title:Polymer-Cased Ammunition for Small Arms and Cannon Ammunition
Abstract:Mississippi Polymer Technologies Inc. (MPT) proposes to develop a new generation of polymeric lightweight ammunition for the use by the services. Previous efforts to develop polymer cased ammunition have failed primarily because of problems associated with choice of case materials. During Phase I, MPT will execute a thorough survey of the available polymers and processing techniques, followed by the development of a comprehensive and rational development plan for implementation during Phase II. During Phase I, in addition to its core material science expertise, MPT will utilize a first Finite Element Analysis (FEA) material model of the cartridge case, developed exclusively for MPT, as well as its exclusive access to its proprietary, revolutionary Parmaxr Self Reinforced Polymers. At the conclusion of Phase I effort, MPT will deliver, in addition to the comprehensive ammunition development plan, three (3) prototypes in specified materials for the Navy testing. MPT was incorporated in January, 2000, its first employees started in June, 2000, and MPT moved into its R&D/Pilot Plant facilities in March, 2002. Since that time MPT has executed projects for the Air Force (high performance structural foams), the Army (lightweight ammunition), the NSF (rapid prototyping), and the Navy (lightweight scuttles and hatches for shipboard use). MPT has received two (2) Phase I SBIR contracts, but no Phase II contracts. Accordingly, there has been little basis for commercializing the results of previous SBIR awards. Nonetheless, MPT is making good progress in commercializing its Parmaxr Self-Reinforced Polymer technology. As one result of its R&D, MPT already has entered into a licensing deal regarding the use of Parmaxr SRPs for coating applications, a deal that included substantial up-front payments to MPT. MPT has grown to twenty-five (25) employees, developed a full pilot plant for Parmaxr SRP resins, and is engaged in advanced process development in preparation for full-scale production of Parmaxr SRP resins for commercial sales. Success in the proposed effort will be instrumental in creating commercialization opportunities for Parmaxr SRP resins. With the anticipated availability of sufficient Parmaxr SRP resin production capacity, MPT will be well poised to provide the materials needed for a wide range of commercial, value-added, Parmaxr SRP applications, including as proposed herein.

Title:Polymer-Cased Ammunition for Small Arms and Cannon Ammunition
Abstract:Replacement of gun ammunition cartridge cases made of brass with cases made of an advanced polymer material would alleviate a portion of the weight burden for Marines and air vehicles caused by the need to carry additional gear and high-tech equipment. The replacement of brass with a high-performance plastic will be investigated for the 0.50 caliber system initially, and if successful, the technology may be transferred to 7.62-mm and 5.56-mm ammunition. 0.50 caliber guns are normally used as armament for helicopters, the Marine V-22 air vehicle, some land vehicles, and the standard Marine rifle platoon, which also has smaller caliber guns in their complement of weapons. The use of plastic cases in all of these weapons can provide a significant weight reduction benefit throughout the logistics train and especially to the end user, the Marines. The proposed program will develop and investigate the feasibility of a polymer case design(s) based on structural, mechanical, thermal and interior ballistic analyses and simulations, properties of candidate high-performance polymers, and manufacturing processes required to produce polymer cases. A search and evaluation study will be performed to identify candidate polymers; subsequently, at least one polymer and case design will be selected for Phase II experimental development, evaluation and demonstration. The successful development of plastic-cased ammunition should result in a weight reduction benefit throughout the logistics train and to the Marine and Army end users. Successful implementation into the U.S. military forces should create opportunities for foreign sales and, if the cost is suitable, for commercial sales in the civilian market.

Title:Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Primer
Abstract:This Small Business Innovative Research Phase 1 Project provides a novel approach to the development of a single pack and zero-VOC primer for the Marine Corps' land based equipment. The technical approach to this primer involves comparison of three polymer concepts (i.e. water borne acrylic, epoxy-ketamine, and moisture cured urethane (MCU). All will utilize VOC exempt solvents. The formulations may incorporate a nanotechnology based filler system. These coatings incorporate state of the art materials to meet the durability, performance and application demands envisioned by the military for the foreseeable future. Functionalized inorganic metal oxide nanoparticles provide a means to enhance the film's barrier properties and to detoxify any CWA agent that comes into contact with the nano-filler material. This feature reduces the demand for cross-linking as a means to mitigate chemical agent transport through the film. The development will consider the synthesis techniques that provide the best overall life cycle cost. These formulations will be tested using a simplified screening protocol that will quickly identify the candidate that has the best prospect for delivering the requisite performance. This innovative approach to the design of high performance industrial coatings will have a profound impact on a global market that exceeds 5 billion dollars in annual revenues. There is a keen interest in materials that will meet and/or exceed the EPA requirements. This scientific advance will serve the environmental needs of the planet without a compromise in performance properties. Isotron Corporation is in a unique position to advance this science into a viable coating system and is prepared to make these materials available to the world.

Title:Development of a Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Primer
Abstract:Spectrum Coating Laboratories, Inc. proposes to develop a single component, zero VOC primer using moisture cured resins and diluents and evaluate the feasibility of these materials for use as primers chemical agent resistant coatings systems. Spectrum will synthesize the resins and diluents, conduct a pigment compatibility study and characterize the resultant formulations. The proposed materials and formulations are based on Spectrum's chemical agent resistant primers currently in use by the USMC. This approach is expected to reduce the cost of development, and expedite the commercialization of this technology. The primer requires no specialized equipment and allows for rapid change of color in the field This material can be transitioned into Spectrum's Commercial/Industrial coatings and Maintenance/Architectural coatings to produce single component, zero VOC materials. The result is a series of environmentally friendly coatings for use in a wide variety of applications. These coatings will allow both the federal Government and private industries to meet current and future regulations regarding VOC levels for coating facilities.

Title:Single Component, Zero Volatile Organic Compound, Chemical Agent Resistant Primer
Abstract:Current chemical and corrosion resistant primers for land and amphibious military vehicles are two component solvent or waterborne epoxy coatings. Unfortunately, problems with component mixing and concentration errors with these multi-component paints often compromise coating performance in the field. Therefore, TDA Research, Inc. (TDA) proposes to develop a zero volatile organic compound, waterborne, single component, chemical agent resistant (1K Z-VOC) primer that will eliminate the need for mixing to ensure consistent coating performance and have no impact on air quality. In Phase I TDA will develop the resin system, which achieves satisfactory viscosity for application by spray, brush or roller. We will make clear coats to demonstrate the curing chemistry and we will test film formation and coating performance. In Phase II we complete development and testing of the coating, including field test and long-term durability studies. Single-component coatings offer simple application and reliable performance. They offer ease of use and eliminate the problem of mixing errors during application that can compromise performance in the field. Additionally, as environmental standards for VOC emissions on coating become increasing more stringent, zero-VOC systems become more desirable. The single-component zero-VOC epoxy system we propose to develop will be used not only by the U.S. military, but will also find wide use in architectural, industrial maintenance and transportation coatings where high chemical and weathering resistance is required, and where application with standard equipment and ambient curing is desired.

Abstract:Our main objective will be to develop a single component chemical agent resistant primer which has performance suitable for U.S. Marine Corps (USMC) land based equipment as a drop-in replacement for the current exterior primers while having zero volatile organic compounds (VOCs). UDC will formulate environmentally friendly, chemical agent resistant latex with coupling agents. This material will be compatible with brush and conventional air-atomized spray application methods. Full cured performance of the final primer formulation will be obtainable at ambient room temperature conditions within 2 to 3 days. These primers will be applied on aluminum 2024T3 and steel 1010 substrates for lab testing. The primed substrates will be tested for chemical agent resistance, bond strength, corrosion protection and abrasion resistance. At the end of Phase I, we will provide a report with results and conclusions Phase II plan and cost estimate. This program will provide a single component environmentally friendly chemical agent resistant primer. This technology will be utilized by the architectural, industrial maintenance, and transportation industries for the painting of equipment requiring high chemical and weathering resistance, particularly where ambient curing and the use of standard application equipment is desired.

Title:Improved Propeller De-Icing Systems
Abstract:The de-icing systems for propellers on Navy aircraft can be improved by using electrical sliding fiber contacts and an integrated electrical contact ring assembly. The electrical sliding contacts proposed will be fiber brushes rather than solid monolithic contacts. These contacts have demonstrated the ability to carry large currents at high speed in contaminated environments of oil and dirt. The brush will be designed along with its holder to minimize losses, reduce wear, improve reliability and simplify maintenance. The fiber diameter and length will be determined to meet design goals as well as selecting the fiber material itself and its fabrication process. The slip ring electrical contact assembly will be designed using filament winding techniques to produce an integrated assembly capable of with standing expected temperature gradients, vibration and electrical heating without performance degradation of assembly failure. The best metal surface treatment of the slip rings will be determined to minimize wear and extend life. The feasibility of using an inductively coupled heater, which eliminates the sliding contracts, will be determined including its ability to meet Navy EMI requirements. The Phase I option program will fabricate a sample brush and holder designed in the base program to show feasibility. A sub scale slip ring assembly will also be constructed with one copper slip ring to demonstrate fabrication techniques. A test apparatus will be designed to simulate operating conditions for the complete de-icing systems in preparation for laboratory testing in Phase II. The proposed electrical sliding contacts and slip ring assembly will eliminate assembly failure by using advanced composite design and fabrication techniques. The use of fiber brushes will reduce wear and electrical losses while having the ability to function in adverse environments and oil contaminations. Maintenance will be a minimum with the expected time intervals of much more than 1000 hrs.

Title:Passive Rocket Motor Identification
Abstract:We are proposing to develop unique and innovative Passive Missile Warning signature processing algorithms to meet threat identification needs and optimize IRCM protection for today''s military and civilian aircraft from the early generation AND today''s advanced IR missile threats. Our missile identification algorithm concepts concentrate on real time situational awareness processing of rocket motor radiated emissions, flight profiles kinematic characteristics and aircraft flight computer data to downsize the potential threat list to smaller more manageable lists for optimized tactical IRCM initiation. As the IR threat technologies advance, they also become more difficult to defeat from an IRCM perspective. It would be invaluable to know the type of missile being launched in terms of being able to narrow down the list of countermeasure techniques needed to be implemented to achieve the required aircraft protection levels. Commercialization of the rocket motor identification technology will involve product development, marketing and distribution of the associated MWS upgrades for both military and commercial IRCM applications. Primary candidates for commercialization of our MWS upgrade technology is for commercial aircraft, executive jets and Head of State IRCM applications.

Title:A Spectral-Temporal Sensor for Rocket Motor ID
Abstract:We propose to design a unique sensor that will be capable of providing detection and real-time classification of rocket-propelled and explosive projectile threats from airborne platforms. The approach will take advantage of the simultaneous temporal and spectral signature data already acquired using an existing chromotomographic hyperspectral imaging sensor to identify and exploit relevant spectral-temporal discriminants for real-time rocket motor identification. The new sensor will be designed to unambiguously acquire the spectral-temporal signature of rocket motors for use as the input to current classification algorithms, and be configured for optimal spectral resolution around the phenomenologically important spectral regions identified during the analysis of existing data. The sensor will also be able to passively locate and track the projectile threat throughout its flight from launch inception. It will have no moving parts and a small physical form factor. The design and development of this sensor represents a unique opportunity in spectral-temporal sensing. This effort will benefit the development of compact sensors for exploiting time-evolving spectral signatures of point-like events. This spectral imager will be able to sample the data at rates in excess of 200 spectral signatures per second for un-cued events within a wide field of view. The proposed sensor will be capable of extracting the spectral-temporal signatures for a wide range of dynamic events due to the simple opto-mechanical design and optimization in phenomenologically rich spectral bands. In addition to tactical defense against explosive projectile threats to aircraft, this technology will lead to advancements in strategic missile threat warning, directed energy detection and warning, bomb damage assessment, and automatic location and identification of artillery and small-arms fire. The ability of the new sensor concept to rapidly acquire spectral signatures should provide an unprecedented opportunity to further investigate algorithms for dynamic event classification based on spectral-temporal signatures. In addition, the small physical size of the sensor will demonstrate the possibility of placing an advanced spectral-temporal sensing capability in unconventional vehicles and locations, thus providing tactical missile tail warning for both military and commercial aircraft. It is further anticipated that the new sensor will find utility in bomb damage assessment and situational awareness of battlespace dynamic events.

Title:Ultrapure, Spherical, Monodisperse, Unagglomerated Nanopowders for Infrared Window Materials
Abstract:The objective of this Small Business Innovation Research Phase I project is to develop a novel process for fabricating nanocrystalline ceramic powders for infrared windows. Nano-grained ceramic materials are expected to have sufficient mechanical properties to operate efficiently under the harsh operational environments experienced by infrared window materials on aircraft and missiles. In our proposed work, we will use an innovative method to fabricate nanocrystalline yttria powders for infrared window materials. High quality nano-yttria powder will be synthesized using a chemical precipitation route. The precipitate will undergo a series of agglomerate-reduction steps to yield a high purity, monodisperse, agglomerate-free powder. A very low temperature crystallization process is proposed instead of a conventional solid-state calcination step. This low temperature step is the key to obtaining agglomerate-free powder with final particle size of less than 25 nm. A narrow particle size distribution and high purity are some of the other benefits of the proposed process. Successful completion of Phases I and II of the proposed project will result in an alternate synthesis method for manufacturing nano-powders for infrared windows and other advanced ceramic applications. The market for nano-ceramic powders is projected to reach $156 million by 2003. When this exploding market opportunity is coupled with the defense (industry and government) and commercial market needs for more durable infrared materials, a significant commercial opportunity for these products is expected to develop in the near future. There are three distinct components to our commercialization strategy: (1) fabrication of nano-powders for Government agencies, (2) fabrication of nano-powders for captive use and for sale to other manufacturers, and (3) fabrication of near net shape end products using nano-powders.

Abstract:The proposed program will demonstrate the feasibility of a novel process to synthesize ultrapure, spherical, monodispersed, unagglomerated yttrium oxide nanopowders. These nanopowders will facilitate the fabrication of fully dense infrared windows. Yttrium oxide nanopowders will be made by sonochemical method. The starting materials to be used are pure yttrium nitrate or yttrium chloride or yttrium acetate, suitable solvent and surfactant to keep the particles separated. The effect of various solvents and surfactants will be studied as well as different parameters for sonication such as sonication time and frequency that will be optimized to make monodispersed, unagglomerated nanopowders with diameters less than 25 nanometers. These nanopowders will be characterized for their phase purity, particle size distribution and chemical composition. This process is scalable for larger and more economical quantities of powder.

Title:An economical and environmentally acceptable process for high quality nanopowders of Magnesium Fluoride (and related fluorides)
Abstract:Building upon our newly developed chemical synthesis process, which is now being used to produce oxide nanopowders with exceptional particle characteristics, we propose to develop an economical and environmentally acceptable process for producing high quality sinterable nanopowders of fluoride compounds (e.g. MgF2 and CaF2) that can be consolidated into fully dense and transparent infrared transparent windows and domes. The impetus for nanopowders as starting material is that the potential exists for consolidating them into ultrafine grained components with mechanical properties far superior to their coarse grained counterparts, and possibly sapphire, which is the benchmark material. In keeping with this objective, we will demonstrate the feasibility of producing nanopowders of MgF2. As synthesized powders will be characterized by an array of analytical techniques, and test quantities of nanopowders will be provided to the Navy by the end of the Phase I program for further testing. Additionally, the sinterability of the nanopowders will be demonstrated. The synthesis process will be optimized and scaled in Phase II, and nanopowders will be provided to manufacturers of IR windows and domes. We anticipate the nanopowders developed in this program to become one of our growing product lines beginning toward the end of Phase II and into Phase III. MgF2 and related compounds fall into a category of materials generally referred to as specialty materials, as opposed to commodity powders such as silica, alumina, and titania. The number of suppliers as well as users of specialty powders is restricted to a few companies. For a variety of reasons, for certain materials, there is either only one, or in some cases, no US manufacturer. This creates a commercial opportunity for a small US based company such as ours. The market size for specialty materials, even if relatively small, is still in the several hundreds of millions of dollars.

Title:Ultrapure, Spherical, Monodisperse, Unagglomerated Nanopowders for Infrared Window Materials
Abstract:Physical Sciences Inc. (PSI) proposes to fabricate high quality ceramic nanoparticles using an electrostatically controlled spray process. Although the commercial production of nanoparticles has steadily increased over the last several years, the use of nanoparticles for optical ceramic fabrication has been limited. Theoretical expectations have not been met with existing methods due to particle impurities, broad size distributions, and shape anomalies. In the proposed process, cost-effective ultra-high purity reagents and streamlined handling methods will be used to synthesize the materials. The integration of electrostatic control during the formation, transportation, and collection of the particles will be used to assure high quality and efficiency is maintained. At the point of particle formation the development of a multi-element array will increase product throughput to reach suggested manufacturing levels. Successful completion of the Phase 1 program will demonstrate the production of monodisperse, sub-25 nm, high-purity ceramic nanoparticles meeting the need for improved ceramic materials. The total world market for nanoparticulate materials reached $492.5 million in 2000 and is expected to grow at an average annual rate of 12.8% over the next 5 years. Consumers include both commercial and military companies. A partial list of applications for ceramic nanomaterials currently includes uses as abrasives, phosphors, fuel cells, cosmetics, and hard coatings. Success of the proposed technology will allow the nanopowders produced to gain immediate acceptance into existing markets. Additionally, new markets within the areas of structural ceramics and optics will be formed.

Title:Non-Polymer Optical Fiber Coatings
Abstract:The objective of the project is to evaluate and to apply a newly developed nano-particale material (NPM) as an attractive substitute for polymer coatings of optical glass fibers. The NPM is both hermetic and low modulus and possesses several additional marits: immunity to corrosion, good adhesion to the adjacent materials,hydrophobicity, practically infinite lifetime, "self-healing" ability, etc. The NPM application will enable one to reduce considerably the outer diameter of the coated fiber and to make the fiber highly mecanically reliable, environmentally duarable and extremely cost effective. The preliminary test data are very encouraging. The new coating design will be very attractive to both leading (large) optical fiber manufacturers, as well as to small companies. No significant changes in the existing drawing equipment are necessary. The application of the proposed design will result in higher quality and lower cost of the photonics products employing silica opticalc fibers.

Title:Dual Hybrid Glass Non-Polymer Coatings for Optical Fibers
Abstract:Hybrid Glass Technologies Inc.(HGT) proposes to develop novel, hybrid glass based protective coatings for optical fibers. These dual layer coatings not swellable by water or organic solvents will possess the hermetic properties that eliminate water corrosion of the fiber, provide mechanical protection, significantly reduce the diameter of the coated fiber and substantially improve the fiber lifetime and reliability performance. The hybrid glass formulation is either heat or UV-curable and will be fully compatible with current coating techniques and systems. Due to the hybrid material viscoelastic properties and its ability to form strong chemical bonds with the glass surface, the novel coatings will eliminate the problems with fiber terminations and splicing and reduce microbending losses of the fiber. The coating components will be synthesized by a well controlled, cost effective, environmentally benign modified sol-gel process. The formulations for the hybrid glass coatings will be low viscosity, solvent free clear liquids, stabilized to achieve a long shelf life. They will be able to cure rapidly and therefore be applied on-line during fiber drawing. The planned process will produce a class of inorganic-organic hybrid glass formulations yielding superadherent, hermetic coatings with tailored hardness and of excellent mechanical, chemical and environmental stability. While the most immediate applications of the non-polymer hybrid coatings being developed under this phase I SBIR project, are targeted to optical fibers in adverse military environment, all of today's commercial telecom fibers as well as photonic components can potentially be impacted by the proposed HGT effort. More than 99% of all current optical fibers employ UV-cured polymer coatings that make them vulnerable to significant strength reduction and eventual failure in the field. This is clearly a dual use materials technology that is being proposed. Major fiber manufacturers such as Corning Incorporated, OFS-Fitel and Alcatel are potential licensees of a next generation optical fiber coatings. In addition, low cost hermetic packaging technology for electronic and optoelectronic circuity might also benefit from this R&D effort. Emerging civilian markets for next generation optical fibers will include a diversity of applications including fiber to home(FTTH), intelligent infrastracture, environmental monitoring, biomedical imaging, automative sensing and smart packaging.

Title:Nanocomposite Coatings for Optical Fibers
Abstract:Fiber-optic technology is finding increasing importance in a wide range of applications within the navy, such as in structural health monitoring of warships, high-resolution image transmission, guided weapons, gyros and optical motherboards for computers. Optical fibers are typically enclosed in a hermetic layer over the cladding that protects the core and the cladding from mechanical, thermal and chemical damage. Various polymeric materials are applied on the surface of the glass fiber to protect it from the harsh environment. Polymers, however, absorb moisture; as a result, long-term mechanical reliability of polymer-coated fibers might be not as high as necessary. An alternative effective coating material that possesses the merits of organic polymers and carbon/metallic hermetic coating, without the drawbacks of these materials, is proposed in this phase I proposal. Apart from use in the navy for fabrication of high-security, high-performance communication networks, the optical fibers developed will also find use in a plethora of civilian applications that involve optical communication.

Title:Air Antisubmarine Warfare Environmental Characterization Using Existing Tactical Sensors
Abstract:Air ASW search rates are critically dependent upon source-receiver separations, which are in turn driven by acoustic propagation and noise characteristics. To optimize the search rate, an accurate environmental assessment must be performed. The current techniques of using monostatic reverberation to invert for scattering strength and geo-acoustic parameters is fundamentally limited by the fact that all reverberant energy must propagate from the source to the bottom and then back to the receiver. A technique is proposed to simultaneously invert monostatic reverberation and direct blast propagation recordings using existing sources and sonobuoys. A physically consistent sediment model is used to permit extrapolation of acoustic predictions in frequency or source/receiver depths. ORINCON proposes to couple this environmental characterization with the development of a search-update algorithm to permit the optimization of air ASW search rates via the incorporation of tactical acoustic data taken while conducting the search, rather than during a preflight environmental characterization. In Phase I of this research, the self-consistent inversion approach, using tactical data and the search-update rule set, will be developed. These will be incorporated into the Geo-Acoustic Inversion Toolbox (GAIT) program of SPAWAR PMW-155 during Phase II and demonstrated at-sea, in real time, using existing tactical sensors. Optimal deployment of current Navy air-deployed ASW systems in the littoral is limited by the sensitivity of acoustic propagation to environmental parameters. A hybrid approach is presented which utilizes acoustic information taken during a submarine search to update the search pattern and therefore optimize search rates. Within the Navy, there is a wide base of customers with interest in technology that can characterize an environment concurrent with the conduct of an active acoustic ASW search. The technique proposed can be extended to other active acoustic environmental applications, such as oil exploration, marine mammal mitigation studies, and ocean acoustic tomography.

Title:Air Antisubmarine Warfare (ASW) Environmental Characterization using Existing Tactical Sensors
Abstract:New ways are sought to improve air ASW search performance by estimating acoustic environmental parameters using existing Fleet assets. Successful ASW missions require characterization of the environment that is accurate, current, and local. Current techniques include pre-mission planning efforts using historical databases, and in-situ mission updates using BT and future TAM buoys. Using existing Fleet assets to accurately estimate environmental parameters provides real opportunities to augment these efforts, increase ASW search rate performance, and improve mission effectiveness. RDA proposes using tactical sensors to characterize the environment continuously and in real-time. Robust methods to measure ambient noise and reverberation levels are outlined using standard air Navy sensors including DIFAR and ADAR receiver buoys. Using solutions outlined for saturation and clipping effects, the transmission loss can also be measured. Bottom-loss and bottom-scattering strength are estimated using an iterative technique based on genetic algorithms and simulated annealing. RDA provides broad experience in air Navy ASW operations including design and development of source and receiver buoys, in-buoy signal processing, RF links, digital signal processing, and real-time systems. A number of benefits are expected from the work and efforts of this SBIR. First is the ability to provide to the Navy operator an accurate, real-time characterization of the operating environment during the mission search phase. Second is immediate feedback of mission performance, with direction to improve the performance. Third is an improved ASW search rate. Additional benefits include an inexpensive yet effective method for environmental characterization that finds broad application in military, coast guard, weather watch, environment monitoring, and wildlife protection efforts.

Title:Environmental Characterization using Tactical Sensors
Abstract:Environmental information is critical to successful littoral Air ASW multistatic search operations. Environmental information is used to optimize buoy field spacing, frequency band selection, and classifier parameters in systems such as Improved Extended Echo Ranging (IEER) and Distant Thunder. In littoral ASW, tactically important environmental parameters are local, time-varying and require `in-situ' measurements. Signal Systems Corporations, with its teammate The University of Washington - Applied Physics Laboratory, will examine alternatives to developing a new tactical acoustic measurement buoy. We will focus on using existing fleet assets with small modifications to buoys and aircraft. Our concepts come from developments in the Beartrap Environmental Characterization, and Non-Traditional Acoustic Processing programs. Environmental Characterization using Tactical Sensors (ECTS) can utilize a ping-while-drop deployment to obtain environmental information during the search operation itself. Because of the difficulties in saturation effects, we will examine the use of extended dynamic range buoys to provide bottom parameter extraction results, and to estimate ambient noise levels. Existing sonobuoys would be used for sound speed profile estimation. In Phase I, we will examine bottom parameter and ambient noise estimation using extended dynamic range ADAR sonobuoys. We will also develop a concept of operations that merges tactical search and ECTS. If this innovative approach shows feasibility, the resulting ECTS capability offers lower cost and reduced logistics demands for in-situ enviornmental characterization. Reduced time to an operational capability is also anticipated.

Title:Low-Cost Optical Air Data System for Weapon Applications
Abstract:Abstract: Currently, there is a lack of proven sensors that can provide winds and density ahead of a weapon system, while still meeting the requirements of low observability/size/weight/power/cost and high reliability. Guidance of a weapon system would benefit greatly with air data knowledge, particularly during the terminal phase when sub-munitions are released. Michigan Aerospace Corporation proposes to investigate the application of its Molecular Optical Air Data System (MOADS) technology for use on a glide weapon system. Preliminary requirements indicate the need for an instrument that will measure wind speed and density ahead of the weapon during its release, glide and terminal phases. Michigan Aerospace has been developing LIDAR (Light Detection and Ranging) and air data system technology that can potentially meet these needs. Based on recent technical and cost studies, Michigan Aerospace determined that a low-cost instrument based on MOADS will meet most of the threshold requirements and many of the objective requirements of a glide weapon system. This proposed Phase I effort will include improvements to the concept design, laboratory testing of the concept and refinement of the production cost estimates A low-cost air data system has significant commercial potential for the intended application, glide weapon systems, especially in light of current events. It also has application to a number of other government and civilian program areas, including stealth aircraft air data systems, turbulence detection, UAV-based wind measurement, ground-based Doppler LIDAR, and space-based LIDAR systems.

The sensor involves a fully fiber-optic LIDAR (laser radar) design, which allows the system to be lightweight, compact and rugged. The technology developed in this project will have applications well beyond the scope of this specific project, and will apply to both the military and commercial markets. Specific techniques developed in this effort will further advance the state-of-the-art in both the atmospheric sensing and fiber-optic disciplines, and greatly enhance the current knowledge of optical and remote sensing.

Title:Intelligent Object Oriented Software Testing Technology
Abstract:The objective of this SBIR project is to develop an Intelligent Object Oriented Software Testing Scheme for conducting software tests, with emphasis on integration and regression testing of complex systems such as the Tactical Tomahawk Weapons Control System (TTWCS). SSCI and our partners (Boeing Mission Planning Systems and Prof. Daniel Jackson at MIT) propose to develop this novel scheme using object-oriented testcase design, machine readable XML technology, data-mining of test results, iterative software testing methodology, and specification and requirement analysis. The proposed scheme will significantly automate the software testing process, as well as the analysis of test results, and lead to higher software reliability and lower testing cost. The Phase I effort will produce a software library in an object-oriented language, which allows test engineers to conduct iterative testing of complex, distributed and data driven software systems in an efficient manner, and a tool to compare and manage the log files. Phase II will focus on developing test result analysis tools using XML and data-mining technologies, as well as a simple, intuitive user interface for the test analysts with the ability to make complex queries of the test data. Boeing MPS has extensive experience in the development, testing, and integration of the Tomahawk Mission Planning System, and will partner as a subcontractor to SSCI in the development of various components in the proposed testing scheme. Professor Jackson from MIT will provide consulting support in the areas of software specification analysis and testing methods. Though our proposed software testing scheme is focused on integration testing of TTWCS, it is general enough for testing a wide variety of software systems, such as commercial vehicle control systems, financial software, and medical diagnostic systems. Given the ubiquitous nature of software systems in this technology-intensive age, and the increasing demand for higher reliability of such systems, the proposed scheme has enormous commercial potential, in both public and private sectors.

Title:Intelligent Test Data Analysis Technology (IT-DAT)
Abstract:Modern weapon and aircraft control systems are software intensive, containing many complex internal and external interfaces. Accurate testing is vital to ensure that the system is functioning properly and will meet all operational requirements. For the most part, current testing focuses on components and subsystems; it is labor intensive and relies heavily on the subjective judgment of expert personnel for an overall system perspective. There are few automated systems to aid in the collection and interpretation of software data, and the few systems that do exist still rely on the interpretation of data by system experts. This project will develop a more-thorough test and evaluation process, which will also be more efficient. The project will utilize the latest in artificial intelligence techniques to automatically analyze data collected during testing, thereby reducing reliance on error-prone manual data analysis. The project will incorporate a database archiving all test related data and system artifacts, providing a query capability for data analysts to review system requirements, identify trends in data, and compare test collected data against historical data. The project will use proven technologies in the collection and archiving of data, leveraging existing tools such as the SEA CORP SEAHAWK, TOWERS, and ADCAS tools. Intelligent Test Data Analysis Technology will improve the fidelity of the testing of complex systems. Through increased automation, this technology will also reduce manpower requirements and shorten the time required for testing resulting in savings and improved operational turnaround times. Concentrating first on complex weapon and aircraft control systems, the application of this technology has great spillover potential in the commercial market. As the reliance on software and external and internal interface becomes more pervasive in manufacturing, engineering, financial and other sectors, the demand for expert system test methods will increase as well.

Title:Automated Generation of Usability Prototypes and Tactical Software
Abstract:Currently available rapid prototyping tools provide limited support in developing well designed interactive, software. The objective of this proposal is to build a user interface design environment for user interface designers in The Discovery MachineT with the following features: ˙ Link all phases and products of the design process through common representational formalisms, ˙ Automate user interface evaluation through the use of design critics, ˙ Modify visual and functional aspects of the design quickly and graphically while still creating a functional prototype, ˙ Expedite the generation of a user interface satisfying requirements through more efficient and productive design, test, re-design cycles, and, ˙ Automate the generation of object models and software interfaces to be accessed by application software components. Here we propose a user interface design environment which involves building on existing knowledge capture and problem solving tool called The Discovery Machine. The Discovery Machine provides design experts with a way to describe an interface that is natural and does not require detailed knowledge of abstract cognitive concepts or complicated programming syntax. The user interface design environment we propose will establish the framework for end-to-end user interface design without writing code. The most significant development within the target business sector is the explosion in amount and complexity of data and the subsequent need for computational power to utilize this data. Programmers, SMEs, and Decision Makers all need more effective tools for communicating to each other and for leveraging this information. The Discovery Machine provides both a vehicle for developing software for communicating, modeling, and analyzing complex processes and the information and objects flowing through that processes. The commercial market opportunity for more effective utilization of data and the scientists, researchers, and analysts who interpret and use that data is extraordinary, particularly given the explosion in data collection and warehousing and the scarcity of skilled experts who can make use of that data. The key target market for Discovery Machine is data-intensive segments in the defense and systems engineering/design sectors. They have a particular need for more effective formalized software development tools, and this has already been validated by over 50 interviews with potential customers and partners.

Title:Using UIML to Automate Generation of Usability Prototypes and Tactical Software
Abstract:Harmonia proposes a novel approach to automatically generating tactical human/computer interface (HCI) code and object design data from the user interface design developed through usability prototyping. This approach uses the User Interface Markup Language (UIML), an open specification language being standardized by OASIS, as a user interface design language that can be rendered to usability prototypes, tactical HCI code, and object model representations. The proposed approach centers on defining an enhanced, UIML-based user interface design process, and then defining tool support needs for this process. The intent is to span the gap between usability and object-oriented software engineering by supporting rapid prototyping of user interfaces for usability engineering, while providing the ability to generate object design data for the overall system's object model and tactical HCI code for deployment. UIML and its associated tools form a bridge between the user interface designer and the application modeler, allowing early and frequent integration of the user interface design process and the application development life cycle. Bridging the gap between usability and software engineering is expected to save considerable effort by eliminating the manual work currently required to move from usability prototype to tactical HCI software. Potential commercial applications are with any software development activity that includes a human/computer interface.

Title:Real Time, Handheld Ultrasound Camera For Inspecting Inner Pipe and Tubing Surfaces
Abstract:Piping and tubing represent a particularly difficult inspection challenge in industry. With access limited to the outside surface of a target, conventional A-scan ultrasonics is usually the inspection technique of choice. However, this A-scan technology is very tedious and difficult to interpret. We propose developing a real time high resolution ultrasound camera for this problem. The ultrasound camera represents an approach whereby an inspector could place a probe up to a tube, such as an aircraft tail hook, and get instant imagery of subsurface faults. The lens based system is analogous to conventional camcorders which are sensitive to visible light. The basis of the technology is a two-dimensional array of pixels, each element being sensitive to ultrasound. This technology can be pervasive over a wide range of industrial and medical applications. Piping and tubing is a very large industry which could greatly benefit from a real time ultrasound camera system. The chemical and petrochemical industries are among the many users of such a device. The low cost (under $10,000) production unit price will allow a high level of market penetration. This same production system could be adapted for the aerospace, medical, and food and beverage industries.

Title:Portable, Hand-Held Inspection System for Aircraft Components
Abstract:New technology is needed for the nondestructive detection and characterization of defects in aerospace structures, particularly those with complex shapes, that are used in high stress environments that accelerate degradation. Existing nondestructive evaluation (NDE) techniques, based on ultrasonics, eddy-currents, and x-radiography do not have the capabilities needed for real-time defect detection and imaging using highly portable instrumentation. RMD proposes an NDE instrument based on an array of magnetoresistive (MR) sensor elements used to produce real-time images of induced magnetic fields within tubular structures. Recent advances indicate that both linear and 2-D MR sensor arrays can be fabricated with sensor dimensions less than 1 mil. A sensor array containing minute sensor elements could provide high spatial resolution images of induced magnetic fields that are perturbed by small defects. Correlating the magnetic field properties at many points, with the positions where the measurements are made, allows the generation of real-time, 3-D images of defects. The sensitivity of a coil is limited to approximately 2.50 x 10-4 T/?Hz while MR sensors have achieved sensitivity of approximately 1.0 x 10-11 T/?Hz. MR sensors have bandwidth greater than 1 GHz, they can withstand forces of 100,000g, and temperatures over 2000C. The PI and his collaborators have been able to develop MR sensor systems for recovering data on obsolete or damaged magnetic tapes, and for detecting cracks and corrosion in sheet metal. Recent advances in sensor design and addressing suggest that a linear array for imaging defects in metals should now be feasible. The new inspection and imaging technology will find a number of markets in nondestructive evaluation (NDE) including the aircraft, electronics, automotive, chemical, and power industries. It will be give inspectors a major new technology for ensuring the condition and safety of aircraft, pipelines, transportation vehicles, and power plants.

Title:Real-Time Ultrasound Camera Inspection of Fasteners in Aerospace Structures
Abstract:While ultrasound is the benchmark technique for inspecting flaws in aging aerospace structures, it is a slow and difficult technique to utilize. To address this need, Imperium proposes to utilize a novel ultrasound camera to instantly inspect cracks and corrosion under fasteners. The system will provide a real time, subsurface view of faults in structures while generating a live video output to an inspector. For example, this handheld ultrasound camera can replace complex gantry squirter systems and scanning systems. The intituitive imagery requires less training than conventional ultrasound systems. While this topic is focused on finding faults around fasteners, a variety of additional applications can be address with this technology with little modifications. Corrosion, delaminations, voids and other faults can also be immediately imaged and quantified. This Phase I program will investigate the feasibility of adapting the ultrasound camera for the real time inspection of fasteners through different shear wave and longitudinal implementations of the system. Commercial, small, lightweight easily used ultrasound cameras could find wide application in both military and commercial sectors. Their use could extend from the inspection of aging military and commercial aircraft to a variety of other applications such as looking at cracks in welds. Furthermore, this same type of camera could be used in a medical application to inspect beneath a person's skin for soft tissue conditions such as cancerous tumors.

Title:Field Portable System for Electromagnetic Imaging of Damage Under Fasteners
Abstract:The proposed effort addresses the need for a hand-held field portable system, including a "shoulder-mounted" instrument, for rapid inspection under fastener heads for corrosion and cracks. The focus is on detection of small corner cracks and corrosion under ferrous and nonferrous fasteners with inspection time well under 30 seconds for real-time decision support. This effort is complementary to JENTEK's ongoing efforts to deliver eddy current array sensor and system solutions to the Navy for field, depot, and production use. Successful completion of this program will meet the need from JENTEK's DoD and non-government customers for a portable low-cost system for field inspections and enhanced capabilities for detection of cracks under fasteners. In Phase I, JENTEK will evaluate performance tradeoffs resulting from miniaturization, design a small portable unit for detecting cracks and corrosion under fasteners for specific NAVAIR applications, adapt our 7-channel probe and calibration and measurement procedures for detection of cracks under both aluminum and steel fastener heads in aluminum skins, and demonstrate capability on representative specimens. In Phase II, JENTEK will "optimize" the system for portability, fabricate a portable instrument prototype, run depot tests, and work with NAVAIR to accommodate form and function requests for final commercial systems. Successful completion of the Phase I and Phase II effort will provide the Navy with a real-time portable inspection system solution for detection of cracks under fasteners. This system will provide rapid inspection of fasteners with a low level of false indications and a high POD for detection of small corner cracks under fasteners. Furthermore, it will support detection and imaging of corrosion under fasteners. The availability of a low cost portable MWM-Array system that supports both scanning and embedded MWM-Array sensors should provide the Navy with a substantial improvement in field inspection capability with a high return on investment. The addition of a low cost portable MWM-Array system is also a key component of JENTEK's long term commercialization strategy.

Title:Real-Time Inspection of Fasteners in Aerospace Structures
Abstract:As military aircraft limits are continuously extended, there is an equivalent need to develop improved and more effective non-destructive evaluation (NDE) techniques for detection of flaws. This especially applies to the development of NDE techniques, which are capable of rapidly detect and visualize flaws, defects and discontinuities in aircraft fasteners. TPL has been developing a new NDE technology based on giant magnetoresistive (GMR) sensors. Such sensors are ultrasensitive to magnetic fields and are highly effective in locating defects and quantifying their magnitude. Sensor arrays can be established on handheld devices for a rapid and accurate detection and visualization of hidden flaws in fasteners. In Phase I a prototype GMR based NDE imaging system will be developed. To prove the feasibility of the system, it will be used to scan a sample surface with irregularities (steps), mimicking the aircraft fastener-skin interface. The resolution and the scanning time will be assessed and compared with the ones prescribed by the Navy. TPL is a leader in the development of GMR-NDE technology. The principal investigator has extensive experience in magnetic field sensors. The major commercial benefit of the GMR based NDE imaging system proposed will be the development of a technology for rapid detection of flaws in conductive materials with non-uniform surfaces. This applies especially to commercial aircraft NDE techniques for non-destructive detection and imaging of flaws, defects and discontinuities in fasteners and similar parts and surfaces. This technology could also be successfully used for flaws detection and imaging of various industrial equipment containing flanges. Such an example would be industrial reaction vessels under pressure.

Title:Localized Reinforcement of Navy Helicopter Transmission Housings
Abstract:A magnesium alloy is used for many Navy helicopter gearbox and main transmission housings. There are two durability related concerns for these components: 1) housing service life is currently limited due to fretting fatigue and corrosion problems; and 2) several heavily loaded points in the housing (e.g., linkage/actuator attachment) will experience even more severe damage. Foster-Miller's approach to resolve this problem is to selectively reinforce the highly loaded regions of the magnesium casting with a unique metal matrix composite (MMC) insert. Foster-Miller has already demonstrated the use of high strength MMC inserts as localized reinforcement of large aluminum gravity castings. The mechanical performance and environmental resistance of potential MMC insert materials will be studied. The selective reinforcement concept will be demonstrated at a specimen level during the Phase I Base Effort. The Phase II program will involve sub-scale components fabrication and testing. Foster-Miller will work closely with a major military helicopter prime contractor and its foundry suppliers in order to develop a technology with near-term implementation potential. (P-030173) The project will incrementally demonstrate full-scale, production capable technology to produce high durability magnesium alloy castings selectively reinforced with MMC inserts. A clear path to implementation of the technology on Navy helicopters has already been established. The proposed technology has broader applications in replacing certain cast iron, steel, or titanium castings with less expensive and lightweight aluminum/magnesium castings through use of strategically placed MMC inserts. Thus, the technology addresses the overall metal casting industry which is a $29 billion per year industry. Foster-Miller MMC materials could be an attractive alternative for a broad structural (as a light weigh replacement for steels and inexpensive replacement for exotic materials) applications and for specific application where MMCs complex of mechanical, themophysical, and service properties would enable implementation of the materials with unique properties, low cost and versatile fabrication technology.

Title:Novel Main Transmission Design Concepts
Abstract:Rotary aircraft such as the V-22 tilt-rotor and H-53 helicopter use a transmission system to transfer power from the engines to the rotor system. Modern rotary-wing aircraft transmission systems can comprise up to 11% of an aircraft's empty weight. The transmission system gearboxes and rotor brake components are fabricated from relatively heavy metals that are subject to corrosion damage due to the harsh salt-water spray environment experienced by Navy aircraft. These metal housings are also expensive to manufacture due to the nature of the metals used and the fabrication processes required to form the complexly shaped parts. Texas Research Institute Austin, Inc. proposes to develop cost effective, lightweight, damage tolerant polymer composite transmission system component designs to replace currently used metallic components in the V-22 tilt-rotor aircraft. The use of composite materials will reduce the cost and weight of the transmission system while providing a reliable, corrosion free service life with little or no maintenance costs. The use of lighter weight, polymer composite transmission components will increase the power-to-weight ratio of the aircraft and allow for increased aircraft performance or payload. The proposed composite materials will consist of high performance resin systems reinforced with high strength glass and/or carbon fibers. Successful development of lighter weight materials and designs for rotary-wing aircraft transmission systems components that can increase an aircraft's power-to-weight ratio and reduce maintenance costs by eliminating corrosion damage, while increasing durability and reliability, will have immediate military applications in the V-22 tilt-rotor and H-53 helicopter programs. Additional commercial applications can be found in the commercial rotary-wing aircraft and automotive industries where lightweight, low cost, corrosion free transmission components would be desirable.

Title:Rotary Live
Abstract:A rotary amplified liquid proof-mass-damper is proposed. The proposed innovation is based on Bell Helicopter's LIVE, Liquid Inertial Vibration Isolator (LIVE). LIVE is currently installed on the Bell 427 helicopter. The proposed rotary version, thus have legacy and support of a rotary wing aircraft manufacturer. The low-weight, low-cost proposed damper will reduce drive-shaft deflections. In Phase I, Midé will work with Bell Helicopter to ensure that the solution can be installed on legacy aircraft. Active modification of the isolation frequency will also be investigated to allow the solution to be used in non-constant speed shaft applications. This work will build on Bell Helicopter and Midé's Dynamically Tuned Airframe Structures (DTAS) Program. This program was funded by the US Army. In Phase I, Midé will develop and evaluate the effectiveness of the proposed damper to minimize drive-shaft deflections. In addition to the reduction in shaft deflection, Midé will also consider weight, cost, minimal aircraft modifications for installation, and maintainability/repairability. Phase I will also assess the effectiveness of the design on both in-use shafting and supercritical shafting. In Phase II, Midé will develop a prototype and evaluate broadest range of drive-shaft design applications to demonstrate the flexibility of the proposed system. Tests will be used to quantify the effectiveness of damping systems and to improve the damper design. Benefits: A low-cost, low-weight rotary damper will reduce maintenance costs, increase equipment availability, increase safety and reduce structural and human fatigue. Commercial Applications: There is a current and significant interest in the automotive and power transmission industry to reduce vibrations induced by rotary components.

Title:Reduction of Rotary-wing Aircraft Driveshaft Deflection via Damping
Abstract:Prescott Products, as an application for its Composite Building Material CBM(Trademark), is proposing to manufacture composite inserts for rotational tubes that will provide vibration damping and deflection reduction. The development plan is to manufacture cored composite tubes from crosslinked, closed-cell, polyolefin foam. The tube insert will be spiral cut which will allow it to expand and press firmly against the inside wall of a rotating shaft. The thickness, foam charateristics, and carbon/fiberglass/epoxy matrix can be tailored to provide desired levels of vibration and deflection reduction. The development of cored composite tubes has broad military and significant commercial applications. Most every rotary-wing aircraft has hollow rotating shafts. Reduction in vibratory loads and component deflection provides a reduction in required maintenance, improved passenger comfort, and extended life for replacement parts. Development aircraft such as the V-22 Ospray would benefit from CCT technology. Other commercial and military applications could include any hollow rotating shaft.

Title:Automated Interoperability Testing System
Abstract:This proposal intends to show an innovative and iterative approach to solving the large scale federation interoperability problem. Currently large resources including both time and people (and subsequently, dollars), are required to bring a group of disparate federates (models and simulations) together in a joined/interoperable federation. High Level Architecture (HLA) and other standards have helped in making the sum greater than the individual pieces but there are no tools to insure that the rules of HLA as well as data structure are followed. The process is a manual (document) agreement of federation rules that each federate in turn is required to follow. Only when the federation is brought together are these rules "checked". The automated interoperability test tool in this proposal will aid in capturing these rules in an understandable and databased format. The rules will then be used to execute a test federate using COTS and GOTS products that will allow for automated checking of a proposed federate, one that proposes to join the ultimate federation, against the rules and provide reporting on the proposed federates compliance with those rules. The tool will be scalable to include any federation rules that comply with HLA standards. It is anticipated that this effort will allow for a reduction in resources (efficiency and cost savings) necessary for developing and testing large scale federations. The initial beneficiary will be the Department of Defense but the tool will be applicable to any large scale federation whether HLA or not. Transportation models (such as those used for traffic control, aviation or automobile) need large scale distributed simulations that will lend itself to this tool. Models or simulations of manufacturing can also benefit by allowing new plant additions (models) to be tested before being federated with existing simulations.

Title:Automated Interoperability Testing System
Abstract:The advent of the High Level Architecture (HLA) increased the complexity, time, and expense of performing simulation network integration as compared to the previous DIS standard. While DIS was a simple, fixed data protocol running on top of IP/UDP, HLA has many additional complexities, including the Runtime Infrastructure (RTI) and API, unlimited Federation Object Model (FOM) structures, and indeterminate low-level networking configurations. All these new variables have provided additional flexibility in the range of simulation types that HLA can be applied to, however, it has drastically increased the opportunity for network configuration errors, RTI compatibility errors, FOM construction errors, data definition errors, and interaction logic errors. This has drastically increased the amount of time and effort it takes to correctly integrate a new federate into an HLA federation. The need for robust, commercial HLA testing tools is critical. MA,K is proposing a two-prong approach to providing commercial products for HLA testing. MA,K will develop the FOMspy federation analysis tool, and will augment the commercially selling RTIspy product with additional required RTI debugging features. Prototypes will be developed in Phase I for evaluation, and complete implementation of the FOMspy will take place in Phase II. We propose the development of the FOMspy product based on the visual programming paradigm and existing VR-Forces GUI infrastructure. FOMspy would read in the Object Model Template (OMT) file, and the most logical tests would be automatically constructed based on the OMT entries. The user would be provided with two mechanisms for adding custom tests: visual programming through the GUI, and custom programming via a C++ developerâ_Ts toolkit for any new state variables, test conditions, etc. The benefits of the FOMspy are (1) HLA developers would be provided with a great deal of sensible testing capability right out of the box, with the automatic OMT test construction, (2) developers would be able to generate new tests with the GUI programming environment, which can reduce programming errors, (3) the developerâ_Ts API toolkit can provide unlimited extensibility for new tests not represented in the GUI, and (4) by outputting the results to a standard statistical analysis package, all the power of those commercially available tools can be applied to processing the data.

Title:Automated Interoperability Testing System
Abstract:Standardized protocols and technical advances, such as the High Level Architecture (HLA), have made simulation a powerful tool for maintaining military readiness through mission planning and rehearsal, force structure analysis, weapon system acquisition, system testing and evaluation, and training. The HLA provides a standard distributed simulation operating environment that, with federation development and execution expertise, can be used to achieve interoperability among simulations. Key factors for interoperability, such as data model semantics and model behavior are, by design, entirely unaddressed by the HLA standards, so it is necessary to capture them in separate federation agreements. Despite the criticality of federation interoperability to achieving simulation objectives, interoperability testing remains a largely manual and even ad hoc process, and there is no systematic method for capturing and ensuring compliance with federation agreements. Under this SBIR effort Virtual Technology Corporation (VTC) will develop the software architecture, process, and support tools to provide automated testing and verification of candidate federates for acceptance into HLA-based federations. This will enable significantly greater utility from simulation, significantly reduce the time and effort needed for federation integration and testing, and greatly facilitate reuse and composability of simulation elements, benefiting all programs that use distributed simulation. Development of automated interoperability testing tools and technologies will provide a number of benefits for DoD simulation users. This research will significantly improve the efficiency and effectiveness of interoperability testing for simulations, reducing the time and effort (or cost) associated with integration. This will in turn yield greater interoperability and integration of simulations into cohesive federations and will allow greater efforts to be applied toward running the simulations and gaining the desired results from the simulations. This research will also enhance interoperability for simulation components, and thereby increase reuse and composability. Ultimately this will increase the utility of simulation to support DoD requirements for training, analysis, acquisition support, and other applications. This technology can provide significant benefits and return on investment for programs such as Joint Strike Fighter and Navy Aviation Simulation Master Plan that rely heavily on simulation to achieve program objectives.

Title:Wide Field-of-View, Head-Mounted, Visor Optics
Abstract:The Joint Strike Fighter (JSF) program requires industry to design and construct lightweight, head-mounted visor optics to display high-resolution color imagery and symbology for situational awareness and targeting. LSA proposes the AdVOS (Advanced Visor Optic System) to deliver high-resolution, wide field-of-view (FOV) images to immerse the user in a realistic virtual environment while addressing the deficiencies of prior HMDs. The AdVOS minimizes weight and bulkiness, optimizes the display's center-of-gravity, and incorporates flexible optics with curved surface visor display materials that can be integrated into a flight helmet with wide FOV projected out-the-window (OTW) imagery. Our optical system design is revolutionary, focusing the visual information onto the operator's retinas so that relaxed out-the-window viewing is possible. Unlike other head-mounted systems, our system does not require bulky objective and ocular lenses in front of the user's eyes. Our system is more like providing the operators with their own personal wide-screen theater. The AdVOS concept has the added advantage of providing some depth perception by introducing optical parallax to the system. The commercial potential of the AdVOS and its subsystem components is very high. Effective training is significant concern for military operations, so selling to this market will be the first avenue. As the technology matures, it will gain wider acceptance and fuel development of a broad range of new applications in both military and commercial systems. The components of the AdVOS can be used to strengthen and provide enhanced capabilities for all aspects of visual display and virtual reality systems. The system has application in any area that large field-of-view displays could offer significant advantages to the overall experience. Virtual reality technologies such as this will bring major breakthroughs in training, education, entertainment, and many other fields. Entertainment systems, computer, gaming, education, and medicine can all find benefits from incorporation of this technology.

Abstract:The goal of the program is to achieve eye-limited resolution in a head-mounted display with as wide a field of view as possible, a minimized overall weight, and a balanced center of gravity. The optical solutions proposed include options for maximizing performance using current flat panel display device formats, as well as options for future expected flat panel formats. All options will address specifications critical to military helmet display system performance, and will demonstrate dramatic improvements over currently fielded hardware. This phase of the program will develop candidate designs and demonstrate feasibility through analyses. Preliminary mechanical package volume and mass properties will also be estimated. The primary beneficiary of this effort will initially be the government/military sector, including customers involved in training simulation as well as actual military platform users. However, due to the unique low-cost, modular approach offered, there is a substantial potential to breach commercial markets interested in virtual reality equipment.

Title:Compact Waveguide Hologram Projection HMD Visor Optics
Abstract:Physical Optics Corporation (POC) proposes to develop a new compact, lightweight wide-field-of-view visor optics for head (and helmet) mounted displays (HMDs) based on POC's demonstrated aberration-compensated holographic optical element (MAC-HOE) technology. Taking advantage of the flexibility of holography, the HMD optics can be made compact using see-through waveguide image projection conformal to the curved visor substrate, filling a wide field of view (FOV) without bulky optical components. This waveguide projection optics approach would be particularly useful for applications that require see-through capability such as for the Joint Strike Fighter (JSF). Using narrowband red-green-blue MAC-HOEs can significantly reduce the chromatic and geometric aberration introduced by conventional HOEs and refractive optics. This proposal takes on the new challenge of extending the MAC-HOE concept of a full RGB color curved-substrate system combined with unique waveguide image projection for see-through capability. In Phase I, POC will demonstrate the feasibility of the proposed HMD visor optics by computer design and analysis, and by fabricating and demonstrating the key components. The proposed compact, lightweight HMD visor optics will significantly advance head mounted display technology. Applications include virtual environment training, avionics, medicine, education, CAD/CAM, video conferencing, entertainment, and video games.

Title:Motion Imagery Navigation Using Terrain Estimates
Abstract:Air vehicles rely heavily on inertial and satellite sensor feedback for navigation. Sensors such as gyroscopes and global positioning systems can provide accurate vehicle state information, but in many real world situations, these sensors can drift or be jammed, leading to navigation errors that can be especially problematic when operating near terrain features. In this proposal, we present a navigation system capable of estimating a 6-degree of freedom state vector purely from optical sensor input. The system, Motion Imagery Navigation Using Terrain Estimates (MINUTE), is capable of estimating the state (position and orientation) of an unmanned air vehicle (UAV) given a (optional) initial state estimate, an existing terrain elevation map, and an image sequence generated by an onboard sensor. This system first reconstructs a relative terrain map from pairs of images taken by a single camera on the UAV as it flies over terrain. The reconstructed terrain map is then matched against existing elevation data to produce an accurate, geo-referenced estimate of the state of the vehicle. In Phase I, we will design a working MINUTE prototype, study algorithm sensitivity using an existing synthetic data generation package, and address the real-time system requirements. Optical-based navigation state estimation is relevant to any autonomous system moving through a complicated environment. The technology developed could be used for Unmanned Ground Vehicles, Unmanned Aerial Vehicles (e.g., LOCAAS), or observer systems where a human is in the loop controlling the vehicle.

Title:A Robust Image Based Navigation System for an Air Vehicle
Abstract:The objectives of this project (Phase I and II) are to develop an automated, robust, and reliable image based navigation system for an air vehicle. Phase I will (1) develop a mathematical foundation for motion image navigation, (2) formulate the mathematical basis for processing a series of sensed frames to generate the terrain profile and correlating the profile to a pre-defined reference map to provide a positional update (assume robust navigational estimates) (3) formulate the mathematical basis for processing a series of sensed frames to provide a velocity update (assume noisy navigational estimates) (4) define critical camera parameters, air speed, and altitude limitations, (5) estimate navigation accuracy and robustness under varying conditions, and (6) estimate required computing resources to implement this approach in real-time. Phase II will develop and demonstrate a prototype motion image navigator. This demonstration will include a flight test on a Boeing test platform. Phase III will integrate of the motion image navigation technique into an air vehicle. Commercial applications of the approach will also be investigated by SSCI and its subcontractor Boeing during the Phase II and fully developed during the Phase III. The project team consists of Scientific Systems Company Inc. (SSCI) and Boeing Mission Planning System (Boeing MPS). SSCI brings a wealth of expertise in image analysis, computer vision, and guidance, navigation, and controls (GNC) systems. Boeing MPS has expert domain knowledge of the Tomahawk system. Mr. Angelo Corrubia, an expert in Photogrammetry, will support this team as a consultant. The development of the image aided navigation will serve as a foundation for Phase III commercialization. These technologies have a direct market in both military and civilian markets that include unmanned air vehicles.

Title:Imagery Automatic Extraction and Placement System
Abstract:The objective of this project is to develop an imagery automatic extraction and placement system to retrieve and accurately position cultural features on geo-specific terrain. Feature extraction includes noise edge elimination by Gabor filter, edge extraction, polygon simplification by the Hough Transform, and corner extraction. The innovative approach is to utilize Memetic algorithms to group the separate features from stereo pairs in order to recognize and measure cultural feature dimensions and place cultural feature of correct dimensions and texture in terrain databases. Current high-speed digital signal processing (DSP) provides the opportunity for complex image processing and algorithm implementation. The Memetic algorithm presents the statistical confidence of the results. The image-processing tool can be applied to medical diagnosis, automatic image-to map-registration, geodesy and environment monitoring.

Title:Imagery Automatic Extraction/Precision Placement of Cultural Features
Abstract:We propose to design an automated cultural feature extraction and placement system by adding plug-in extensions to an existing COTS package like Imagine, or PCI Geomatica. This system will use sophisticated statistical quality assurance to iteratively refine feature detection and feature extraction. This process will be self adapting to variances in feature properties based on geographic location or time of the year. As an option a fully functional demonstration prototype based on COTS and Vexcel technology will be implemented. This work will to a high degree leverage Vexcel's existing technology for automated 3D mapping and expertise in design and implementation of mapping systems for DOD customers. The proposed automated system would significantly lower the cost speed up production of textured feature databases for government and commercial cliens. Since the system will also support commercial satellite images, it will become possible to create feature databases for international locations, where aerial photography is not available today. With the proposed system in place, Vexcel will be in an excellent position to capture much of this business.

Title:Acoustic Emission Monitor for Drive System Coupling Crack Detection
Abstract:The objective of this Phase I proposal is to present Physical Acoustics Corporation's (PAC) ability to design and develop a reliable, "near" real time monitoring methodology for early detection of cracks in diaphragm-type couplings used in aircraft and engine drive systems. The "near" real time Acoustic Emission (AE) crack detection system is intended to demonstrate the feasibility of using an on-line AE crack detection system to provide suitable advance warning to indicate the presence of cracks and to preclude catastrophic failure. The proposed methodology will tailor PAC's state-of-the-art AE sensing, data acquisition, and Pattern Recognition technique for the development of an on-line AE monitor for drive system coupling crack detection. The development work for Phase I will consist of developing and demonstrating an autonomous adaptive procedure to recognize and classify crack-like AE signals which will simulate cracking in a coupling in the presence of mechanical noise. During the Phase I Option period, the software for Pattern Recognition will be modified to include the calculation for the displacement and velocity metrics that will allow the evaluation of crack growth in the drive system coupling. It is anticipated that the results of this program will lead to the development of a real time AE-based Neural Network Classifier for early detection of cracks in diaphragm-type couplings used in aircraft and engine drive systems. Since the real time crack detection system will provide suitable advance warning to preclude catastrophic failure, it will have applications for many industries beyond the military and could be applied to a broad range of military and commercial aircraft applications.

Title:Increased Impact Protection of the Navy's Aviator Helmets
Abstract:The overall objective of this proposed effort is to develop new energy absorbing liners for Navy aviator helmets providing improved energy absorption properties, equivalent or improved weight, comfort and health characteristics, and that can be manufactured and installed at an acceptable cost. Toward this goal, Dynamic Research, Inc. proposes to collaborate with Brock USA, a manufacturer of innovative energy absorbing materials. A comprehensive analysis of the technical merit of alternative energy absorbing materials would be conducted and candidate materials thus identified. These new materials would be evaluated by physical tests and optimized through the implementation of dynamic finite element models of aviator helmet protective components, and predictive simulation and subsequent verification of ANSI Z90.1 impact tests. Phase I deliverables include a report documenting the results of the material analysis, the test and simulation results of the candidate materials and a preliminary design for new EA liners for the large size helmet. Phase II includes manufacturing and testing a small quantity of prototype liners, additional simulation, and more extensive testing to refine the design as needed. Phase III includes manufacturing a large quantity of EA liners to prove manufacturability, demonstrate durability and ease of replacement, and perform final qualification tests. The primary anticipated outcome of this proposed effort would be a design for improved energy absorbing liners for Navy aviator helmets. This would make it possible for the Navy to upgrade the protective capabilities of its existing HGU-68/P and HGU-84/P aviator helmet inventory at a cost that is less than replacement of complete helmets. Similar liners could have application in other aviator helmets. A second outcome of the proposed effort would be development of a sound technical methodology for designing and evaluating improved head protection equipment using innovative materials. This design methodology could have commercial applications in all areas where improved head protection is required in both the public and private sectors. Design and consultation services and related energy absorbing products could be provided to manufacturers and evaluators of head protection gear. In the private sector this would include manufacturers of recreational helmets intended for use with bicycles, skateboards, inline skates, skiing, climbing, skydiving, motorcycles, and motorsports. Additional manufacturers of head protection related to public and industrial safety (e.g., police, fire, construction) would also benefit from this approach. In the government and military sectors this could also include helmets for, numerous types of aircraft, tanks and other armored vehicles, police riot equipment and other applications.

Title:Increased Impact Protection of the Navy's Aviator Helmets
Abstract:This is a proposal to demonstrate the feasibility of improving impact protection for Navy aviator helmets using SKYDEX patented technology. SKYDEX material absorbs impact through compression of opposed hemispheres formed from durable elastic polymers. Products are custom engineered to meet a customer's specific requirement for shock absorption. SKYDEX technology offers more effective impact protection in less space than traditional cushioning materials like foam or rubber. SKYDEX is involved with several helmet projects. A SKYDEX nape pad for the back of the PASGT infantry helmet was developed for the US Army. In lab testing done at the US Army Aeromedical Research Laboratory at Ft. Rucker, Alabama, the SKYDEX nape pad outperformed the existing nape pad, reducing Peak G scores by over 40%. Field-testing is about to begin. Lab testing done both at Snell Labs in California and BioKinetics in Toronto, Canada also showed SKYDEX materials significantly outperforming current cushioning products. By developing a custom geometry, performing impact testing with different polymers in an aviator helmet, and then refining the geometry and polymer choice based on initial results, we are confident that SKYDEX technology can offer significantly improved impact protection over current Styrofoam liners. SKYDEX technology can improve upon the impact attenuation, heat management and durability offered by current helmet liners. Advances made through this SBIR for aviator helmets can be modified to work with other military helmets as well as products requiring greater impact attenuation. SKYDEX is currently studying "nape" pads for use in paratrooper helmets, boat decking, ejection seat cushions, and padding for the transportation of sensitive military equipment. Helmet linings for cycling, motor sports, football, skiing, skateboarding, hockey, lacrosse etc. could be developed as a result of the knowledge gained from this SBIR. SKYDEX technology has been commercialized to solve problems of impact attenuation in footwear, playground surfaces, and boat decking panels. Several active sports companies (Airwalk skateboard shoes and Burton snowboard boots) are using SKYDEX technology in their midsoles to offer greater protection for landings from high jumps. SKYDEX is selling a safety panel to go under playground surfaces that that offers far greater impact protection than what is currently available. A SKYDEX boat-decking panel is available for both commercial and military boats, which shows great promise for reducing injury to personnel in high-speed, rough water situations. SKYDEX has significant experience in moving products from design, through prototyping to production. Once a final prototype is developed, a production tool can be designed and built in about 3 months. Twin sheet thermoforming production is very efficient and thousands of parts can be produced in a matter of days.

Title:Increased Impact Protection of the Navy's Aviator Helmets
Abstract:Injuries resulting from impacts to the human body, more specifically impacts to the head are a major concern for our society. Up to 2% of the U.S. population lives with disabilities resulting from impacts to the head. A key component in reducing these injuries is managing the momentum exchange between the head and the surface of impact. In this proposal we will determine the feasibility of using a formulation of Team Wendy's ZorbiumTM foam as an improved energy management system for the Navy's HGU-68/P (ejection aircraft) and HGU-84/P (rotary wing aircraft) aviator helmets. Commercially, this technology will be applied to all areas of protective headgear, including action sport headgear, motorcycle helmets, and team sport headgear. It is estimated that information gathered from successful completion of this Phase I proposal may increase sales figures for Team Wendy's current products by up to 30%. Further development using the gathered information will allow Team Wendy to increase its product offerings and engage in private branding and licensing to other protective headgear and body padding manufacturers. Manufacturing and processing issues will be investigated in a subsequent Phase II proposal.

Title:Sonobuoy Launcher
Abstract:The MH-60R multi-mission helicopter as a combat extension of the surface combatant conducts defensive and/or offensive operations in support of the battle group. Time on station is an important factor in successful completion of the helicopter's mission. Reducing the weight of the MH-60R increases it available time on station. The stores launchers onboard are critical mission components that today are separate and add significant weight and volume to the helicopter. A single launcher that can deploy sonobuoys, decoys and chaff would significantly reduce weight and improve stores deployment. Developing a new launcher will also permit new technologies to be added which will provide improved ejection, structural performance, remote function selection and the ability to launch various sized stores. The launcher we propose will be modular in design thus providing a very flexible mission load. The launcher will also be reconfigurable and use state-of-the-art materials that can be molded and sized for the mission load. Innovative mechanisms for the firing devices and launch tubes will be investigated. Reliability, producability and cost are primary drivers in developing the new launcher system. Using a combination of an improved lightweight launcher and lighter sonobuoys, weight savings of up to 500 pounds are projected. Developing a new lightweight, modular, reconfigurable launcher system will greatly enhance the time on station, and thus the operational performance, of the MH-60R helicopter. Use of modern materials such as composites coupled with novel production techniques such as molded tubes will not only significantly reduce cost but also greatly ease the logistics requirements. Eliminating the pneumatic ejection mechanism will enhance the reliability by reducing complexity and safety. In addition to the MH-60R the new launcher will have application with the Coast Guard for drug interdiction, ship acoustic signature collection and smoke marker deployment. Use aboard commercial helicopters will enable oceanographic studies of seismic activities, whale and marine mammal surveys and tracking, and atmospheric and ocean environment sampling. Also, successful development of this launcher will allow for new launcher initiatives in time for incorporation in the Multi-Mission Aircraft (MMA), which would allow for the carriage and launch of a multitude of future sensors and form factors.

Title:AGILE Sonobuoy Launcher
Abstract:Current helicopter sonobuoy launchers are complex, heavy and will not meet future requirements for mission versatility. Because of the complexity of the launcher and its pneumatic subsystem, the launcher has many points of potential failure; its reliability is poor. Further, as in other pneumatic systems involving stored compressed air, the system is subject to vagaries of pressure which can result in uneven or incomplete expulsion of stores. This project will examine the feasibility of an "AGILE" (Airborne Gas Inflator Lightweight Ejector) launcher which will use COTS automotive airbag inflators as a source of sonobuoy ejection energy, a lightweight, modular structure and intelligent controls. The individual AGILE launcher cells are independent of external energy sources. This permits the consideration of innovative concepts for launcher design and operation. The use of inflators also imparts many other advantages. The AGILE Launcher eliminates virtually all moving parts, thus reducing failures and simplifying logistics and maintenance. The proposed launcher will be extremely reliable, lightweight, versatile and safe, with a lower total ownership cost achieved through reduced maintenance, repair and logistics support requirements. Because of SEA CORP's resident experience with this concept, it will be possible to build and test a single-cell launcher in Phase I. The employment of automotive airbag inflators for launch energy has already been shown to present many advantages for lightweight torpedo launchers on surface ships. There are a number of parallels between surface vessel torpedo tubes and sonobuoy launchers: both comprise tubes as launch containers; both have complex breech mechanisms relying on HP air; both launch a cylindrical body from a platform through the air into the water. The mass, velocity and acceleration merely have to be scaled to the airborne application. Among the benefits of the AGILE-type launcher are reduced maintenance and repair (net reduction in required manpower), improved safety, better operational performance and lower total ownership cost. Further, the versatility offered by the self-contained launch tube allows innovative concepts such as modular, all-up-rounds or clips containing several rounds. Placement of the launcher is also more versatile, since the launcher is not dependent on an HP air source. The inflators themselves have a solid record of reliability and safety based on over thirty years of experience with millions in use. This project is an extension of the concept already shown to have commercial potential as witnessed by the Navy's investment of over $5 million in the torpedo launcher development program. Other potential applications include shipboard countermeasures and decoys.

Title:Mid-Frequency Sonobuoy
Abstract:Active multistatic sonar systems have become the preferred solution for shallow water undersea warfare missions. Most airborne active multistatic systems operate in the low frequency range to provide increased range and reverberation resistance. This works well for large area search and localization missions. However, tactical follow up and target tracking are better accomplished by using higher frequencies, which provide high range resolution and speed computation. Tactical platforms such as the MH-60R multi-mission helicopter conduct tactical defensive and offensive operations in support of the battle group. They operate in a multistatic mode with the high power bow sonar source onboard the surface combatant and with their own onboard variable depth ALFS sonar by deploying sonobuoys to receive and transmit the echoes to the helicopter. These systems operate at a higher frequency than where the current receiving sonobuoys operate. Therefore, to optimally operate in a multistatic mode with these higher frequency sources, a new receiver is required which operates in the mid-frequency range of the ship sonars and ALFS. This new receiver will be compatible with existing digital RF links and employ in-buoy beamforming. This new receiver will be capable of significant increase in weapon system operational performance over today's receivers. Developing a new sonobuoy with substantial noise discrimination capability and high gain at higher frequencies than previously achieved leads to smaller and lighter systems. This type of system capability is of interest to the undersea mapping, exploration, seismology and weather communities. Government agencies such as the National Oceanographic and Atmospheric (NOAA) and the Department of Commerce continually upgrade their measurement and data collection capability. These sensors would fulfill a need to provide in-situ measurements at frequencies not ordinarily measured. Also, their role in bottom mapping makes use of similar sensors that are much larger and costly. By developing reliable, low cost sensor components, we can offer them much more capability and performance.

Title:Mid-Frequency Sonobuoy
Abstract:The Navy requires a new Mid-Frequency acoustic receive array to serve as a multistatic receiver intended for use with the SQS-53C Bow Sonar and the ALFS Dipping Sonar. The SBIR solicitation is very specific in terms of the required array gain, digital uplink format/precision, and dynamic range for the new sensor. While this proposed sensor represents a very strong candidate for meeting the Navy's bistatic active receiver requirements, other sensors or combinations of sensors could potentially meet this need as well. RDA believes the Navy should evaluate a spectrum candidate sensors including one that meets the requirements outlined in this solicitation before committing to a single design. In this SBIR, RDA will not only address the sensor requirements called out in the solicitation but also propose and evaluate some additional innovative sensor designs. Each candidate sensor shall be evaluated in terms of mission effectiveness, cost, deployment weight, logistics and technical feasibility. Our Phase I approach is to first perform an analysis of the candidate sensors identified in this proposal. Next, we plan to perform a performance analysis of a number of innovative array geometries. Finally, we plan to conduct a packaging and feasibility analysis for the leading candidate array configurations. The newly developed search sensor will provide the SQS-53C and ALFS systems with an off-board active receive capability thereby increasing the probability of making aspect-dependent target detections. This capability will not only enhance the search capability of those systems but also provide additional self-defense capability for the battle-group. The goal of this effort is to merge the technology developed in Phases I and II into an SQS-53C or ALFS system planned product improvement program in Phase III. In terms of non-military potential, the proposed sensor could be used for monitoring the migration paths of marine mammals. The new sensor could also be of value to the Coast Guard in both its homeland defense and drug interdiction missions.

Title:Advanced Multi-Aircraft Shipboard Landing Model
Abstract:Progress has been made in modeling and simulation of the shipboard operation cases to support analysis of the single aircraft landing task. However, limitations exist where the analysis does not include the interference arising from simultaneous operation of multiple aircraft on the same ship. To improve all aspects, especially flight safety, of shipboard operations with multiple aircraft, the interaction between the ship and the aircraft, as well as between multiple aircraft, must be addressed. We propose to (1) construct and integrate with FLIGHTLAB a prescribed tip vortex model with vortex decay effect to provide an efficient multi-aircraft wake hazard assessment tool and to support parametric study of the effects of upwind aircraft wake on shipboard aircraft landing. (2) enhance Peters/He's finite state dynamic wake model with a far field wake evolution model including wake distortion and decay to support both real-time and non-real-time multi-aircraft operation modeling and analysis. (3) enhance and fully integrate with FLIGHTLAB the time-accurate free vortex wake model by Bhagwat and Leishman for shipboard multi-aircraft interaction analysis. The enhancement will include a high fidelity vortex evolution model to address the vortex core growth and vortex strength variation due to the vorticity diffusion and dissipation. (4) develop and integrate into FLIGHTLAB a unified formulation to couple the ship motion, ship airwake/turbulence, and multi-aircraft interference models and render an advanced ship/aircraft dynamic interface model. (5) extend the development to commercial applications for air traffic control and terminal area operations. This SBIR could potentially result in various commercial products and create strong interest among ship and aircraft designers, researchers, and manufacturers, the military, the FAA, and commercial airline operators. The multi-aircraft interference model developed will benefit aircraft shipboard operations and support the process of design, training, and planning. It will also benefit commercial airlines for take-off and landing safety and improvement of terminal area operation efficiency.

Title:A Fully Coupled Multi-Aircraft DI Simulation Model
Abstract:Attempts to simulate the dynamic interface (DI) environment of landing aircraft onto Navy ships typically incorporate extensive approximations in both the component aerodynamic models and their interaction. These lower fidelity models are employed in order to achieve real-time throughput speeds required in manned simulation, or may simply result from lack of data or sufficient analytical tools in the models themselves. A novel fully-coupled aerodynamic simulation that includes multiple aircraft simultaneously operating from a ship is proposed for development, that will represent time-accurate couplings between aircraft wakes, ship superstructure, and ship airwake emanating from a moving platform. Various modeling simplifications will then be applied to this simulation and their effects evaluated in order to quantify the level of detail necessary to use this software as a DI testing predictive tool. These simplifications should also enable the development of a networked version of this simulation environment that may ultimately achieve real-time throughput speeds through parallel computation. Extensive use will be made of past and current efforts at CDI in real-time aircraft wake simulation, bluff-body aerodynamic analysis, and hybrid CFD approaches that all address the DI aerodynamic environment. The software end product resulting from Phase I/Phase II research would provide a tool for pre-test prediction of the operational environment anticipated for flight near maritime or ground structures subject to external disturbances and prevailing wind effects. These conditions include landing and launching aircraft from ships, operations from off-shore oil platforms, and use of heliports on top of and adjacent to large buildings. An additional benefit of the software would be an enhanced representation of flight operations in structure-generated turbulence to facilitate pilot training.

Title:Development of a Crack Resistant Durable concrete Repair Material for Navy Concrete Structures
Abstract:A large number of existing Navy concrete structures are in a state of deterioration/distress. It must also be recognized that many repaired concrete structures are severely deteriorated only after a few years having been repaired. How to halt the decay of the Navy's physical infrastructure? The durability of concrete repair must be ensured on a basis of daily practice, from the research, design, material selection through construction practices and quality control. Every means of rendering concrete repair technology more reliable has an enormous engineering and economic signficance. The SBIR Phase I project focuses on one of the critical route-cases of preliminary failure of concrete repairs - cracking of repair materials due to the restrained volume changes. The ultimate goal of the project is to develop durable crack-resistant repair material. The key deliverables under the scope of work in Phase I will be: (1) identification fo short-term material criteria for crack-resistant performance; (2) develop candidate mateiral mixture(s) for compliance with the performance criteria; (3) testing the candidate mixture(s) for compliance with the performance criteria; (4) report. The toll paid for loss of service and annoying repair of repairs amounts for enormous amount of money. The present situation with repaired concrete structures sometimes jeopardizes Naval activities. The low crack-resistance of presently avialable on the market cement-based repair materials is one of the causes of unsatisfactory performance of repair structures. Therefore, the research and development project directed on developing repair material(s) with high crack-resistance characteristics will make a substantial contribution not only for U.S. Navy but fro the entire industry.

Title:Free Piston Pump for Microturbines
Abstract:The Navy needs long-life fuel pumps for Microturbines. We propose to apply our patented Free Piston Pump (FPP) technology to develop a long-life fuel pump for Microturbines to meet the needs of the Navy. We have developed our FPP to meet long-life requirements and stringent cost requirements for high-pressure (for example, 3000 psi) cryogenic LNG systems on heavy vehicles. Our FPP has a long life because it has few moving parts and long-life seals. Our FPP has a low cost because it has a low part count of inexpensive parts. In Phase I, we will design, build, and test a prototype Free Piston fuel Pump (FPP) for Microturbines, and we will determine the economic feasibility of large-scale production of our fuel pump. In Phase II, we will: (1) optimize our FPP to maximize life and minimize costs; (2) build and test the optimized design; (3) use the optimized pump to generate performance maps (data); and (4) develop a fuel-pump package (including performance data) suitable for commercial sale in Phase III. In Phase III, we will enter large-scale production of our pump, and we will mass-market our Free Piston Fuel Pump for Microturbines throughout the Navy and the Commercial Sector. Our Free Piston Pump (FPP) is attractive for many applications that require a long-life, low-cost, high-pressure pump. Some promising commercial applications of our FPP are: fuel pumps for Microturbines; fuel pumps for LNG systems on heavy vehicles (trucks); feedpumps for nuclear powered submarines; pumps for desuperheating water injection for steam power plants; and feedpumps for power generation and cogeneration.

Title:Data Model for Battle Force Interoperability Certification
Abstract:Avineon proposes to develop a model for acquiring, organizing, storing, distributing, and analyzing the combat systems data resulting from interoperability tests, corrective actions, upgrades and modifications, during the D-30 process. The analyses will: (1) assist in the determination of readiness, (2) plan modifications and (3) assigning the plans priorities, based upon available budget and criticality. Avineon will develop the System architecture to implement this model. Object oriented analysis and design methods will be used, following the Rational Unified Process (RUP). Requirements, object models and their interactions will be described using UML and Rose visual models. The primary objective is to develop the architectural components of the system. As part of this process, hardware, network, and COTS product components will be evaluated and selected to develop a recommended architecture for a working system with the required functionality. Heterogeneous data sources have traditionally posed problems for mission critical analysis of combat data, thereby reducing the effectiveness of collecting such data. Since data resides on several disparate systems, real time access to and aggregation of that data is difficult. Traditional Data warehousing solutions are by nature static and inflexible. Avineon's proposed Dimensional Object Model is dynamic and flexible and can evolve with advances in processes, methods, and technology. With the recent advances in technologies such as secure P2P, commercially available publish and subscribe models as well as security advances make it possible to access, aggregate and analyze heterogeneous data repositories quickly and efficiently. Applying this technology to combat data will enable battle readiness assessment in mission critical situations. Since the competitive environments in which most corporations operate also require prompt integration and analysis of data from multiple sources, the research proposed herein also has strong potential for successful commercial application.

Title:Data Model for Battle Force Interoperability Certification
Abstract:The objective of work during Phase I is to develop a prototype to show that a representative sample of source data maintained on a commercial relational database management system can be acquired, objectified, and furnished to a client application for use. Phase I will also demonstrate that the data transfer can occur over a secured data network. Data Process Technologies proposes to develop a system to acquire, store, organize, analyze and distribute Battle Force Interoperability Test (BFIT) data collected during the D-30 process. The goal is to assist in determining readiness, making and prioritizing modifications based on criticality and budget. A systems architecture will be developed including database and application design, with Commercial Off-The-Shelf (COTS) software and hardware (including server, client and network) selected and specified based on evaluation and prototyping. The system will include archival information for analysis of historical data. A working prototype will be constructed and demonstrated using the proposed architecture. The problem of determining the readiness and interoperability extends from Naval task forces to multi-service and multi-country forces engaged in joint and combined operations. The system that is developed under this project is expected to be of interest to The US Joint Chiefs of Staff and NATO. The technologies used in this project such as XML and OLAP, although still considered emerging technologies, are not new to the military or to industry. However, the integration of the disparate parts of the proposed system into a well-defined process has vast commercial potential.

Title:Data Model for Battle Force Interoperability Certification
Abstract:Given the events of the past few years, interoperability between elements of large battle forces or joint operations has become even more vital for risk reduction and mission accomplishment. The ability to determine the degree to which such forces are interoperable prior to deployment is therefore critical as part of the overall readiness assessment. Current interoperability testing and analysis involves the use of multiple legacy data sources operating in a standalone mode. The inefficiencies introduced by such an architecture coupled with the inability to `see' all of the data combine to make the process of interoperability certification difficult at best. Trident Systems proposes to build a comprehensive interoperability data model and system architecture, leveraging on-going work in other areas to mitigate risk. Trident has considerable experience in the area of large data model development and integration with legacy sources. In addition, Trident has developed similar prototype and commercially available architectures for data model deployment and thus has considerable experience in the design, build and deployment of such systems. The proposed Interoperability Certification Data Model (ICeDaM) system will enable a new level of battle force interoperability readiness certification, and will positively impact the mission success of large battle forces. The major anticipated benefit is the ability to more quickly and accurately determine battle force, multi-service force and multi-country battle force interoperability readiness. With the initial focus being naval battle forces, the proposed product of this SBIR will provide a promising foundation for use within other services and joint operations (such as NATO). In addition, the complete system will be applicable to law enforcement and emergency response agencies in multi-jurisdictional environments.

Title:Automatic Real-time Computer Aided IDentification (ARCAID)
Abstract:The AQS-20(A) towed minehunting system incorporates an electro-optic imaging lidar sensor that provides high fidelity 3D imagery crucial for identification of mines. While a real-time algorithm to automatically detect, classify, and identify targets from the image outputs of the EO system is entirely feasible, the current AQS-20(A) system support only a rudimentary Automatic Target Detection (ATD) algorithm that has limited capability to differentiate mine-like objects (MLOs) from clutter. Areté proposes development of an Automatic Real-time Computer Aided IDentification (ARCAID) system that would replace the current ATD and greatly expedite target identification and false alarm rejection during AQS-20(A) missions. The ARCAID system will greatly reduce the amount of post-mission analysis required to positively identify mines and discriminate them from mine-like clutter because the real-time algorithm will provide a high level of identification and clutter discrimination on the fly. Additionally, the ARCAID system will incorporate a 3D data visualization tool for man in-the-loop verification of mine identifications. The tool will enable the operator to optimally exploit the 3D data captured by the system by interactively comparing multiple 3D perspective views of mine-like objects (MLOs) identified by the algorithm with identically scaled models of the suspected mines. Areté sees the ARCAID system as a necessary and integral part of the AQS-20(A) EOID system. Because Areté already has experience developing a baseline algorithm for the ARCAID system, Areté believes that it would be a grave mistake to omit such a capability in the fleet-deployment of the AQS-20(A) system. The ARCAID system will greatly enhance the efficiency and accuracy of the AQS-20 mine-hunting mission, which will provide a huge asset to national defense and to the efficacy of our naval warfare.

Title:Ellipsoidal Basis Functions for Computer Aided Identification of Mines
Abstract:The objective of this proposal is to explore and develop a candidate identification algorithm, the Ellipsoidal Basis Functions method and demonstrate capability for computer-aided mine identification with specific exploitation of 3-D information. Currently, mine identification systems rely on post mission processing to complete mining hunting operations. Real-time computer aided detection and computer aided classification (CAD/CAC) is just now being pursued by many researchers in order to reduce operator workloads. We propose to develop the EBF method, utilizing AQS20(A) and other acoustic and or magnetic sensor data to provide an enhanced target discrimination capability as compared to the standard Bayesian Estimation, Correlation/Matched-Filter, or Energy Classifier methods. We note that a significant feature of the EBF method is that it seamlessly lends itself to fusing data from multiple sensors as discussed below and that the EBF method is a fully data-driven method. The method does not require any physical or environmental models or parameters of the observer system. These can be incorporated in the pre-processor if a prior information is available. Also, the EBF method can readily exploit 3-D data since the data is represented as feature vectors, the dimensionality of the data can be arbitrary. The proposed investigation will provide valuable tools and validation for applications of the Ellipsoidal Basis Functions method to areas other than mine-hunting also such as missile and homeland defense as well as object and face recognition technologies. There currently exist various face recognition technologies that have made way into some applications (e.g. Connecticut DMV, West Virginia Child ID programs). The deployed software is still being tested and refined. Most of the techniques currently use a principal components analysis (PCA) followed by extraction of "eigen-faces." We believe the EBF method will provide improved capability to the commercial face recognition technologies. Also, the EBF method has potential applications to current autonomous target recognition programs such as potentially, The Boeing Company''''s SLAM-ER.

Title:Alternative System for Hangar Bay Access Doors
Abstract:The Hangar Bay Deck Edge and Division doors, on aircraft carriers are in need of modification, in order to minimize maintenance and increase reliability. In both current applications, guide rails are recessed into the deck and collect debris, non-skid grit, and oily dirt. Additionally, the wire rope system for operating the doors jams, sometimes causing the rope to part, resulting in significant down time. The LCE/Curtiss-Wright/Burke team proposes changing the door operation system to include electro magnetic levitation (MAGLEV) to raise the door panels a minimum height to release friction. Two independent magnetic lift systems will be utilized for primary and secondary operation systems. The door will be modified to eliminate the blast guide, which slides in the recessed deck trough. The deck guide trough will be eliminated and replaced with 1-2 inch "speed bump" on which the door will travel, that will be recessed into the bottom of the door panels, providing horizontal structure support. The wire rope system will be replaced with worm gear type linear actuators. A secondary pneumatic actuator will be utilized as the secondary means to operate the doors. A control system will provide operation, alarm signals, system status and self-diagnostics. The development of a reliable, quick acting, easy to maintain fire/blast door system, that is scalable to any application, would be highly valuable to Navy ship design managers charged with designing warships that are more capable, while requiring less manpower. Throughout the modern era the US Navy has realized, on numerous occasions, the benefits of superior damage control and firefighting capabilities. Unfortunately, most of the current capabilities in use today, are manpower intensive, which is a luxury the Navy of today cannot afford. The proposed drive system, will maintain the DC and firefighting capability currently employed in CVN design and operation, while increasing the reliability of this system, decreasing required operation and maintenance manpower and simplifying operations.

Title:A High Reliability, Electric Drive System for Carrier Deck Edge Doors
Abstract:The present deck edge door drive system for aircraft carriers is a complex system of sheaves, wire ropes, and associated equipment that has low reliability and high maintenance cost. The main system attributes that result in this situation are the indirect actuation of the door panels, and the use of a heavily loaded track in the hangar deck floor. SatCon is proposing a development program that will address these two issues, replacing the present system with one that uses direct actuation of the door panels and unloads, and potentially eliminates, the deck track. The SatCon solution will make use of electromagnetic lift mechanisms and linear electric machinery drawing on our experience from programs such as the Electromagnetic Aircraft Launch System (EMALS), and collaborating with established naval equipment manufacturers. The system will be significantly more simple to operate and maintain, and have the potential for significant reductions in the total ownership cost for a hangar door actuation system. This initial development, which is targeted for the carrier deck edge doors, is directly applicable to the interior hanger bay division doors. Similar design elements can also likely be applied to other naval linear electric machinery opportunities such as elevator lifts and munitions/missile/torpedo loading mechanisms. Furthermore, similar technology can be applied to markets in the commercial sector for anything from low load, high precision semiconductor manufacturing equipment to large maglev transportation systems.

Title:Alternative Drive System For Deck Edge Elevator
Abstract:The program is to investigate a new drive system for the Deck Edge Elevators for the Next Generation Aircraft Carrier. This drive system is to be electrical in nature and is to replace the current hydraulic engine and hydraulic system. Jered Industries is in a unique position to conduct this investigation due to the vast experience gained with Deck Edge Elevators. Jered Industries has designed and manufactured most of the Deck Edge Elevators currently in service in the US Navy. In addition, Jered Industries was the prime contractor for the Aircraft Elevators for both the Spanish and French Navies. For this study, Jered Industries has teamed with Power Superconductor Applications, Corp.(PSA). PSA has significant experience in linear electric motor technology that we believe will hold the most promising solution for the alternative drive. By eliminating the hydraulic system the following benefits are to be realized: 1. Reduced maintenance cost 2. Reduced maintenance man-hours 3. Reduced operating personnel 4. Reduced overall weight 5. Lower Life Cycle Cost 6. Overall safety improvement 7. Reduced noise level around equipment 8. Cleaner operating environment around equipment

Title:Alternative Drive System For Deck Edge Elevator
Abstract:The deck edge aircraft elevator (ACE), now in use on all active CVs and CVNs, is based on the system design principles established over 40 years ago. This system, while remaining one of the most reliable in the fleet, can be improved upon by employing new technology in the areas of drive mechanism, automated control, and self-diagnostic maintenance assessments. In addition to the improvements available through technology application, the development of an electro-magnetic drive mechanism would allow for the replacement of the current hydraulic engine, thus removing yet another maintenance intensive hydraulic system from the ship, while dovetailing with the Navy's current efforts to maximize electrical system application. The baseline approach, proposed under this SBIR, will be to utilize the existing roller design and implementation of the elevator, but incorporate the linear motors into the structure to provide the needed lifting forces. The major components of this system will be linear motors, power electronic motor controllers, and a supervisory control system that features intelligent controls and a graphical user interface (GUI) for operation and diagnostic entries to the system. The development of an electro-magnetic drive system for heavy lift elevators can be highly valuable to the US Navy and any commercial entities tasked with moving heavy loads through a vertical lift. Currently, the common method of moving heavy lifts is by the use of large hydraulic engines, which require large amounts of hydraulic fluid and require high-pressure pumps. These systems are used in moving cargo onto and out of cargo ships, within port authorities for storing and transferring, in industrial warehouses for loading/unloading flatbed trucks, in shipyards for the movement of structural modules, and for drawbridge applications. An electromagnetic drive mechanism would allow for greater control of these lifts, thus impacting personnel safety and equipment wear and tear. Additional benefits would include a reduction in the need for hazardous material (hydraulic fluid), and a reduction in the preventive maintenance required to maintain the pumps, reservoirs and cylinders associated with large, high-pressure hydraulic systems. Concurrently, an electromagnetic option could be lighter than the current hydraulic motor and lifting cables, thus assisting in on-going weight reduction efforts for the next generation aircraft carrier. Finally, utilizing the technology being developed under the Electro-Magnetic Aircraft Launch System (EMALS), commonality in maintenance/operation/training of control systems, linear motors and power electronics will reduce the overall ownership cost.

Title:Acoustic and Electro-Optic Data Fusion
Abstract:Historically acoustical sensors have performed the bulk of Mine Countermeasures for the Navy. Electro-Optic Identification (EOID) has recently proven itself as an important technology in the identification of mines. With the AN/AQS-20A adaptation program now providing EOIDs to the fleet, the EOID sensor works simultaneously with four sonars (the EOID replaces the Volume Search Sonar for this configuration). To fully exploit the combined capabilities, sonar and EOID data need to be fused into a larger feature description of the target. Arete will create simulated EO images that correspond to existing AQS20 sonar targets and provide a combined acoustical / EO feature set (expected to be greater that 41 raw features). From this set, an algorithm will be developed to describe the target. The existing acoustical CAD/CAC algorithm will be used to measure the added performance attributable to the fusion process. Phase I will quantify the benefit of the fusion process and pave the way for a Phase II. The following phase will analyze the simultaneous data to be acquired during CT / DTOT testing and the releasing of the algorithm for integration into the the AQS20 system. It is fully intentioned that this work will result in a "fusion CAD/CAC" capability for the AQS20 program by linking with CSS's mine feature database. From a broader sense, this work has application for "n" number of fused sensors, whether they are acoustical, IR, visible, polarimetry, spectral, etc. This will help meet the need for difficult target discrimination suing multiple sensors.

Title:Ellipsoidal Basis Functions for Acoustic and Electro-Optic Data Fusion
Abstract:The objective of this proposal is to correlate and fuse data from electro-optic and AQS20(A) acoustic sensor data and provide a single computer-aided mine identification system thus significantly increasing mine identification capability by utilizing the complementary strengths of both types of sensors. The approach will use 2 levels of fusion. The first level (Lower level fusion) will fuse feature vectors, using the ellipsoidal basis functions (EBF) method, obtained from the two sensor types and provide a single identification, thus utilizing greater information afforded by two sensors as opposed to using single sensor data. The second level (Higher level fusion) will consider the fusion of a candidate complementary algorithm in addition to the EBF method. The idea here, discussed in the literature, is that each algorithm has its strengths in suppression of specific false alarms and thus a fusion of complementary algorithms will provide optimal performance. The proposed investigation will provide valuable tools and validation for applications of the Ellipsoidal Basis Functions method to areas other than mine-hunting also such as missile and homeland defense as well as object and face recognition technologies. There currently exist various face recognition technologies that have made way into some applications (e.g. Connecticut DMV, West Virginia Child ID programs). The deployed software is still being tested and refined. Most of the techniques currently use a principal components analysis (PCA) followed by extraction of "eigen-faces."

Title:Underwater Mine Detection Using Acoustic Gap Filler and Electro-optic Sensor Data
Abstract:Feature-based target detection and identification data fusion algorithms have been shown to be effective in classifying land mines and other objects. Several of these algorithms, namely Dempster-Shafer inference, voting logic fusion, and Bayesian inference, may be particularly applicable to the detection of underwater mines. WaveBand will utilize its extensive experience in applying these techniques for selecting and/or developing data fusion methods that are optimal for the underwater mine detection problem using acoustic gap filler and electro-optic sensor data. Our ability to understand the strengths and limitations of data fusion algorithms and the information required as inputs to the algorithms makes WaveBand the ideal candidate to address this challenge for the Navy. The algorithms cited require expert knowledge or information that is frequently obtained from the results of "offline" experiments. WaveBand has extensive experience in conducting these experiments and analyzing and applying the resulting data to data fusion processing. This project will enable WaveBand to enhance its capability to build and market MMW sensors, which incorporate data fusion processing utilizing other sensor data when they are available. The enhanced images or object classification information achievable with the multi-sensor system will improve upon the state of the art in that objects that may be hidden or have degraded signatures in one sensor's signature domain but may not be hidden in another. Many sensor systems currently under development, which frequently suffer from degraded imagery or target classification ability under limited visibility conditions, can be upgraded using the results of the proposed project.

Title:High Efficiency Mission Performance for Underwater Expendable Countermeasure Devices Commonality Applications
Abstract:Integrated electronics, control, and navigation/propulsion modifications will be investigated to provide 40% improved efficiency for ADC Mk II operations. Leveraging its UUV-development expertise, Nekton will focus on: 1) design of a linear navigational control system to replace existing solenoids, 2) design deployable, recessed, mid-body fins for lift enabling efficient high speed level navigation, and 3) design of FPGA/DSP-based electronics to significantly reduce electronics power and space requirements, which will free-up space for a shallow recess in the outer hull surface to accommodate deployable fins. Phase II will yield a prototype for field tests. ANTICIPATIED BENEFITS: The proposed effort will significantly improve the range and velocity of the Mk II, initial estimates exceed 40%, while also improving its control and eliminating the characteristic (detectable) swimming pattern now employed to accommodate negative buoyancy and lack of lift. Following the Phase I specification and initial design, Phase II will complete design and yield a prototype incorporating the specified enhancements. In addition to providing a low cost reliable solution to the identified deficiency of the Mk II, the proposed effort also addresses technology issues in anticipation of Next Generation Countermeasures development. COMMERCIAL APPLICATIONS: The components developed under this effort are optimized for the military mission but the subassemblies clearly are applicable in UUVs for environmental monitoring or research, as well as tactical oceanography, mine countermeasures, and plume mapping or other toxicant detection missions.

Title:High sensitivity, pressure compensated optical hydrophone
Abstract:Fiber optic sensor systems are a key element in the Navy's plan for meeting cost, reliability and performance objectives for future towed and fixed arrays. A cost effective optical hydrophone that provides performance over the full operating environment is needed to meet future requirements and mitigate technical risk in several ongoing development programs. Multiple candidate designs are presented that overcome limitations in current optical hydrophones with a minimal increase in overall complexity. Additionally, pressure compensated solutions are described which maintain compatibility with thin line towed array design constraints. These candidate implementations will be fully evaluated during phase 1 efforts. Engineering evaluation includes modeling, analysis, prototype fabrication and in water tests to quantify trade offs early in development. Consideration of application specific derived requirements including sensor interrogation methods, optical noise floor performance, durability during handling, insensitivity to vibration and compatibility with automated array manufacturing techniques are also critical to ensure a successful integration into current development projects such as the fiber optic TB-29 thin-line towed array. The range of alternatives identified provides increased sensitivity over the entire range of operating environments resulting in suppression of other noise mechanisms inherent in optical sensor systems. The primary benefit is improved sensor sensitivity resulting in suppression of noise mechanisms that may limit fiber optic sensor performance. This performance benefit is achieved while maintaining compatibility with physical packaging constraints and production cost objectives. The higher sensitivity hydrophone will make all optical interrogation systems more practical and will have application in both towed and fixed arrays used by the Navy and the seismic industry.

Title:Develop and Evaluate Alternative Hullform Technology for the 11 Meter Ridgid Inflatable Boat
Abstract:In consideration of the operational requirements of the US Navy VSW/MCM forces to transport marine mammals, this investigation evaluates alternative hullform and innovative technologies to reduce shock transmission to occupants and mammals. Specifically, this investigation evaluates and compares the vertical accelerations, boat signature, and hull resistance of the air lubricated/supported STOLKRAFT hull to the Naval Special Forces 11 Meter Rigid Inflatable Boat. Improved seakeeping and ride quality have become increasingly important to developers and owners of high speed craft. In adddition, to US Navy applications in the Special Forces arena, certain enterpriese have begun to develop platform, manned and unmanned, to carry personnel and electronic sensors at high speeds and into rough seas. Many of the sophisticated electronics in production and under development have strict requirements on the limitation of vertical accelerations. In addition, civilian commercial applications such as waterborne ambulances and fisheries transport craft have similar requirements to the transport of marine mammals. With the identification of requirements in Phase I, the team will obtain a thorough foundation for the assessment of the Stolkraft as the hullform that will significantly improve performance, reduce vertical accelerations, and minimize slamming loads. The investigation will provide validated data that will be directly useable in the design of vessels for the safe and comfortable transport of marine mammals.

Title:Develop and Evaluate Alternative Hullform Technology for the 11 Meter Ridgid Inflatable Boat
Abstract:This topic was written to improve the ride quality, wake and efficiency of high speed water craft through optimized hullforms. This quest has continued worldwide for almost a century, but nothing has supplanted the deep vee hull for rough water use. Instead of new fiberglass hull shapes, we investigate an `add on' fix, active stabilization with fast moving control surfaces, made practical by new developments in inertial sensing and motion control systems. Ride control systems are common on large fast ferries and military aircraft, but are not currently available for small planing craft. In Phase 1 offshore demonstrations we will quantitatively demonstrate signature, range, and ride quality improvements using transom flaps and more sophisticated submerged foil systems. Long-term potential payoff to the US Navy could include fielding a faster, more efficient and effective combatant craft.

Title:Develop and Evaluate Alternative Hullform Technology for the 11 Meter Ridgid Inflatable Boat
Abstract:Littoral Research Group L.L.C. (LRG) of New Orleans, Louisiana proposes the development of a high-speed, high-lift planing hull form that significantly reduces the environmental signature and shock imparted on the vessel and its occupants. Moreover, they offer the practical implementation of new concepts and design methodologies that focus on hull-form technology for the exploitation of the hydrodynamic/aerodynamic properties as shock mitigation tools. LRG will analyze the 11-meter RIB to establish the analysis benchmark for the sea-keeping characteristics at static, loiter, semi-planing, and planing speed. They will identify and analyze alternative hull forms that hold the potential to improve special operations capabilities, including Mammal and Diver Insertion/Extraction operations of the Very Shallow Water Mine Counter Measures forces (VSW MCM). LRG is prepared to integrate into the new design lift/drag ratio enhancing and shock mitigating devices. The lift/drag ratio enhancing devices could be a set of low profile retractable semi-lift hydrofoils. Because the craft envisioned would be highly focused in design, the larger commercial potential is in high speed personnel transport, like commuting to offshore rigs, a comfortable crossing from Miami to Bimini, or a ferry trip from Seattle to Victoria B.C. Littoral Research Group L.L.C. (LRG) anticipates extending the design developments of the 11-meter RIB's hull geometry to the commercial market segment. Because the craft envisioned would be highly focused in design, the larger commercial potential is in high speed personnel transport to the offshore rigs, a comfortable crossing from Miami to Bimini, or a ferry trip from Seattle to Victoria B.C. Currently the Navy is developing a fleet of Unmanned Surface Vessels (USV) in the support of the Future Naval Capabilities (FNC) mandate. This fleet is being developed from the 7-meter and 11-meter RIB platforms because they have shown the capability to support such operations as mine countermeasures, amphibious warfare support,communi- cation relay with UUVs, and a significant number of other functions. LRG views the research, development, and deployment of the 11-meter RIB as a large step toward a fully autonomous fleet capable of patrol, mine counter measures, communications, and amphibious warfare support. Beginning in the year 2006, marine diesel engines over 37-kW will be required to meet new clean air standards. Recreational marine engines contribute to ozone formation and high PM (particulate matter) levels, especially in marinas, which are often located in areas with air-quality problems. The use of the new hull design technology to assist in meeting the new standards will have a profound positive effect on the air quality in our marinas and National Parks.

Title:Knowledge Gathering Network for BFMIS
Abstract:Avineon proposes to develop an intelligence gathering system to identify and monitor the knowledge gained from the integration of system interoperability management data (Risk analysis, BF Comparisons, Metrics, DMSAR, Program TRs, BF CM data, BF ECM analysis) with mission analysis, system models, requirements, network models, and functional analyses. This effort will also document knowledge management processes that exist or are required for effective utilization of knowledge resulting from a combination of multiple BF systems. Avineon will define a generalized knowledge architecture including the structure of the data warehouse, interfaces to data sources, operational processes, affected user groups, and responsible organizational entities which can be developed into an XML-based data warehouse to serve as the foundation of a knowledge-based system architecture that captures system configuration, certification, operational, and test data along with a description of the organizational groups and processes that utilize this information and data. Object oriented analysis and design methods will be used, following the Rational Unified Process (RUP). Requirements, object models and their interactions will be described using UML and Rose visual models. As part of the process, hardware, network, and COTS product components will be evaluated and selected to suggest a working system representing the selected architecture. The results of this research will enable the BF community to define how the information gained from improved interoperability can be easily and quickly analyzed to provide knowledge that enables decision makers to decide where and how improvements can be made and to determine how the new knowledge can be created or gained in a systematic fashion. Moreover, heterogeneous data sources have traditionally posed problems for mission critical analysis of combat data, thereby reducing the effectiveness of collecting such data. Since data resides on several disparate systems, real time access, and aggregation of that data is difficult. Results of the proposed work will enable the development of knowledge systems with the ability to analyze data and information, pose questions regarding performance and requirements improvements, and recommend where and how efforts can be made to improve overall performance. Applying this technology to combat data will enable battle readiness assessment in mission critical situations. Since the competitive environments in which most corporations operate also require prompt integration and analysis of data from multiple sources, the research proposed herein also has strong potential for successful commercial application.

Title:Knowledge Gathering Network for BFMIS
Abstract:Data Process Technologies proposes to use process modeling, value chain analysis and risk management procedures to help define, manage and develop aircraft carrier battle group (CVBG) interoperability testing processes. This work will provide certification team members with best practices and lessons learned guidance to enhance the CVBG certification process and streamline process activities used to reach critical decision points. Results will be standardized and promulgated using a centralized application, the Rational Unified Process (RUP). A software tool will be developed to help managers navigate the shoals of the certification process. In this manner, the combined knowledge can be used as a tool for risk assessment and mitigation, and to share the knowledge with others. In other words, the goal is to help managers define and share the activities that add value to their process, regardless of the role they play in battle group certification. Improved definition of activities will ensure that deployment critical interoperability milestones are met, while those activities adding little value can be deleted from the certification process. For those activities that have borderline value, risk management techniques can be applied to ensure the best bang for the certification "buck." This will help managers improve their understanding of risk from the holistic view of deploying a carrier battle group. The sharing of knowledge will help standardize the certification process. The net result will be faster, more reliable and complete certification methodologies. There are many opportunities to provide a complete process modeling, analysis, reengineering, risk management and knowledge management solution in the Navy, DoD, in Federal and state government and in the private sector. This need is anticipated to result in additional contracting opportunities for Data Process Technologies. Examples of Navy scenarios where this type of solution may prove beneficial include Administrative Material Inspections (ADMAT), Operational Readiness Evaluations (ORE), Operational Readiness Inspections (ORI), Operational Propulsion Plant Examinations (OPPE), Planned Maintenance System (PMS), Fast Cruises/Dock Trials; i.e. essentially any scenario where complex processes exist. Literature and anecdotal evidence suggest that highly complex tasks lead to an inability to perform them successfully.

Title:Knowledge Gathering Network Assistant (KGNA) for the Navy's BFIMS
Abstract:Battle Force communities face increasingly complex data sources and information overload in their interoperability engineering process. Therefore, interoperable Battle Forces require information support systems with superior knowledge creation, documentation and dissemination features. Improved search, knowledge management, data mining and learning techniques of a new Knowledge Gathering Network Assistant (KGNA) can help create actionable knowledge to improve that Battle Force Interoperability Management System (BFIMS) process. The KGNA can enhance the BF community's: 1) deep discovery of relevant knowledge from external sources; 2) decision-making with timely critical insight for specific tasks, 3) pattern detection from both structured and unstructured sources, and 4) exposure of critical relationships to better measure and improve BFIMS performance. Phase I efforts for KGNA development will help build the foundation for a knowledge system that manages BFIMS interfaces, collects required data and selects proper data mining and decision support tools to embody knowledge creation, documentation, and dissemination with modern associative learning methods. In Phase II and Phase III efforts, a KGNA module will be constructed and tested that can interface with existing computing and network facilities of the BFIMS. Knowledge management via associative learning will help the BF community grasp, solve, formalize, and measure effectiveness of interoperability solutions. Knowledge management processes of the armed services and commercial enterprises can benefit from superior data mining and deep discovery that the KGNA offers. Business intelligence derived from data mining of warehoused information can sustain the competitive advantage for knowledge-centered organizations.

Title:ALSSYST: Multimedia-enabled Advanced Logistics Support System for Shipboard Use
Abstract:The operational nature of submarines causes personnel to heavily rely on the available training and technical documentation for shipboard equipment. These technical documents are currently being converted from paper to a structured publishable data format (XML/SGML) and then loaded in object-oriented databases and the Navy's Content Management System (i.e., Evolution from Outstart). The traditional approach of separating technical documentation and training products is impractical for the COTS based electronics systems being procured today because frequent (annual) system design changes are being introduced to implement performance improvements. What is needed is an integrated technical documentation and training product that is capable of providing interactive system operation requirements and just in time operation and maintenance training for complex COTS based electronic systems. This SBIR will create an advanced logistics support system that exploits state-of-the-art multimedia technologies in support of training and maintenance costs. Rapid cost-effective, training and maintenance of complex equipment through integrated technical instruction and training framework. ALSSYS can be repackaged as a computer-based equipment operation and training product in vertical commercial markets.

Title:Low Cost Submarine UAV Communications and Sensor Data Link
Abstract:The Navy requires a long distance data link between a UAV and a submarine, which supports transfer of both high bandwidth surveillance data, and command /control messages. This data link must employ a highly secure, covert, and cost-effective design. Initial analysis contained in the proposal shows that the central issue in such a design is the balance between surveillance image quality (which requires significant bandwidth), obtainable UAV prime power, and UAV antenna characteristics. Both power and antenna configuration are constrained by other aspects of the UAV design. It is proposed to develop a spread-sheet based tool which will support trade-off analysis among various choices of frequencies, modulation / compression schemes, power requirements and antennas. Using this tool, appropriate parameters values will be selected, major components chosen, and a sample design presented at a block diagram level. Cost, size, weight and power requirements will be estimated for this design. In addition to meeting Navy requirements, the data link which is designed using this tool will have commercial value for UAV-based surveillance by other government agencies, highway traffic observation, for patrolling assets such as high voltage transmission lines and oil pipe lines, and for private security services. The design will comprise a significant improvement over previous systems, in terms of range and image quality vs. cost. At the same time, by limiting power requirements and antenna size, it will be possible to use inexpensive UAVs derived from model airplane practice.

Title:Low Cost Submarine UAV Communications and Sensor Data Link
Abstract:We propose to design and conduct feasibility trade studies for a low-cost communication system and data link for a disposable Unmanned Aerial Vehicle in response to FY2003 SBIR topic N03-047. The key aspect of our approach will be to reduce the lifecycle cost of an airborne line-of-sight TCDL data-link and increase the range of the data link to be limited only by the UAV altitude, up to a distance of 200 miles. The project will accomplish this goal by utilizing a Communication System Pointer based on Ross-Hime Designs, Inc. Omni-Wrist III, a low-cost, lightweight, compact, high dexterity pointing device and a state-of-the-art high gain directional Ku band antenna. The Omni-Wrist III offers hemispherical 2 pi steradians of singularity-free precision movement, low manufacturing costs, and a simple design. The Omni-Wrist III also reduces the complexity of a typical Ku band directional antenna by allowing the RF feed and pointer to be virtually maintenance-free. Ross-Hime Designs, Inc. (RHD) of Minneapolis, Minnesota has over 16 U.S. Patents on robot joints. Lockheed Martin Tactical Systems (LMTS) of Eagan, Minnesota is a prime item integrator for the USN with domain knowledge in C4SI systems development. Benefits expected to arise from the proposed work include: high capacity multimedia data exchange; jam-resistance communication; small transmit/receive aperture; low-power and weight; and resistance to EMI and co-site interference. Potential commercial applications include: high-bandwidth video transmission; long-distance communication links; and remote sensing.

Title:High Bandwidth, Hull Mounted Array Telemetry and Display System
Abstract:Driven by the need to operate in acoustically challenging littoral environments, the need for high-channel count, large aperture hull mounted arrays have created a demand for low cost telemetry electronics and operator processing/display aids that are suitable for large sonar arrays. The proposed telemetry approach leverages the existing TAIPT and Total Ship Monitoring telemetry systems to provide low cost electronics suitable for large sonar arrays. This approach continues to use a two-level telemetry architecture that combines a scaleable COTS ATM/SONET network with a simple, high-speed bit serial sensor telemetry. This telemetry approach has demonstrated the ability to synchronize thousands of distributed platform sensors over the same network used to transfer data. This standard network interface simplifies the connection to platform processing resources. The signal and information processing impacts of these voluminous sensors are unavoidable because large number of sensors translates to a large natural beam set (thousands) to form a large search space. While computer resources have increased, operator resources have remained the same. The processing and display system makes best use of computational power, automation technology, and display concepts to achieve desired sensor system performance with available system manning. The high bandwidth, low cost, hull mounted array telemetry developed under this SBIR has direct applications to future submarine sonars including upper, medium and low frequency bow conformal arrays, mine hunting and collision avoidance sonars. Since the proposed telemetry is scaleable over frequency and provides a full duplex uplink and downlink it has the ability to transfer complex shipboard generated waveforms to transducers for transmit and receive arrays. This type of telemetry is directly applicable to seismic survey and reservoir monitoring activities for both land and marine applications. Survey crews typically install a grid of velocity sensors (geophones) in large prearranged fields. A typical field may contain as many as 100,000 channels whose signals are multiplexed together and sent to a recording station via an optical or electrical signal path. The processing and display architecture work under this SBIR is directly applicable to future work in submarine combat systems. The Large Hull Array (LHA) sensor, or similar new concepts are certainly candidates for Advanced Processor Builds (APB) in the medium term. It is expected to use the developed architecture, design and integration concepts for the basis of future functional additions. The tasks under this SBIR have wide applicability to new sensor system like the Navy's DD(X) next generation surface ship, which is expected to include more extensive sonar sensor concepts.

Title:Innovative Display Concepts for Interacting with Large Dimensional Acoustic Arrays
Abstract:To counter the ever-growing trend in submarine quieting, the complexity of detection systems has increased to the point where thousands of display surfaces of raw data would be required if today's method of presenting information to an operator were followed. These new sensors, coming on-line soon, are capable of providing information to an operator not previously available that needs to be exploited to its full extent. Concepts to present the information gathered from these complex sensors must provide the information required by the decision maker without generating an overburdening workload on the analyst. New display formats must be designed and built to provide the analyst with access to the new measurements, and the information must be combined so that an operator need only search a reasonable number of display surfaces. Inherent in all of the combination schemes tried to date, there has been a loss of signal processing gain that the complex sensor was designed to achieve. ORINCON proposes to develop new techniques that use ORINCON's expertise in understanding the total picture (underlying physics, automation, automatic signal detection, identification, correlation and tracking) to assemble a view that contains only the detected signals. An automated drill-down capability would be included to expose the hidden dimensions. ORINCON's concepts will permit analysts to rapidly scan the outputs of the new larger dimensional arrays to gain a rapid grasp of the new features available with less loss of weak signals from the new complex sensors. This would allow human analysts to take maximum advantage of the new capabilities to detect weak signals as if they were searching through a vastly larger number of display surfaces.

Title:A Low cost High-performance Data Network for Large Acoustic Arrays
Abstract:Rydal Research proposes to research and demonstrate the feasibility of developing a low cost high-performance data network that will support the size and speed requirements of the next generation of large hull-mounted acoustic arrays. The network will be based on a number of novel low cost high-speed electrical and optical networking components and an efficient low-latency open protocol standard. The network will provide data rates in the 10 Gb/s range with latencies in the range of a few hundred nanoseconds. The network will also be used to implement a high performance real-time distributed processing system. Feasibility will be demonstrated by modeling and simulation and demonstration of small network prototype in Phase I. The development of this technology will benefit the Navy in a number of ways. It will dramatically reduce the cost and improve the performance, reliability, and insertion time of large acoustic arrays. The processing system based on these components will provide more than an order of magnitude improvement in processing throughput. Since the same protocol will be used for both data distribution and processing, the resulting flat architecture and simplified programming model will further contribute to lower cost. Finally, the development of low-cost components enabling economical high-performance computing and signal processing will spur commercial and academic research and development in operating systems, algorithms, and software development tools based on them. This research and development will further reduce the cost and improve performance of future Navy systems.

Title:Autonomous Damage Controls of Submarine HM&E Systems
Abstract:Achieving reduced manning and lower O&M cost for the Virginia class submarine depends upon successful automation of labor intensive functions. Previous attempts have not produced the desired reduction because potential manning reductions achieved through automation were negated by battle damage control manning needs. Successful manning reduction requires automation of previously manual damage control functions and is achievable through autonomous distributed HM&E operational controls. Foster-Miller has developed a component-level distributed control system (CLIDICS) for the control of shipboard electrical power grids (under Navy Project N00014- 98-C-0229). The system model developed identifies system faults by a reasoning process that detects abnormal operation and determines the root cause. It also reacts faster than humans and identifies the optimum work-around reconfiguration. Applying the underlying design process, component level specifications can be developed for any of the HM&E systems for autonomous battle damage detection and system reconfiguration as well as performing normal system function verification. The Trim and Drain System was selected for the proposed development of damage detection and reconfiguration algorithms, and selection of suitable COTS hardware for the shipboard system. The CLIDICS based autonomous control system design specification will have sufficient detail to allow building a prototype system in Phase II. (P-030192) American industry's need to improve productivity and reduce the labor content of products has been dictated by the pressures of global competition. Although process automation has made progress, it has been ultimately limited by the realities of process machinery faults and required maintenance manning. The lack of reliable early machinery fault detection, prognosis and good autonomous process reconfiguration has reduced the effectiveness of process automation in much the same way that the battle damage manning issue has affected the Navy's attempts to reduce manning. The success of this current project can have a very positive effect on American industry's success in meeting the current and future challenges of global competition. The dual use technology insertion from this project will provide industry with the technology and design process needed to enhance the economic performance of previously introduced process automation. In addition, component-level control functions and devices developed under this project could be used in applications where short reaction time and high survivability are required such as commercial ship HM&E systems, passenger aircraft, and nuclear power plants.

Title:System Automation That Will Support Reduced Manning On Submarines (Component-Level Distributed Control System Technology)
Abstract:An engineering focus on alternative approaches to the unique aspects of shipboard damage control and maintenance that require significantly higher levels of manning. The ideal solution for low cost wireless shipboard automation is comprised of: current wireless Local Area Network (LAN) technology; handheld or wearable personal computers; networked IEEE 1451 "plug and play" sensors; and accessibility to current application software coupled to Human-Machine Cognition features. Protecting an investment in this arena means making use of well-established industry standards for wireless computing, connectivity, and alliances with proven vendors. The proposed approach is to develop technology solutions from near term products and technologies to provide the Submarine Force with the tools it needs to increase productivity while reducing manning The thrust of this effort is the embodiment of the concept of "pervasive computing", which by its nature makes the computer invisible to human interaction. Pervasive computing implies the computer has the capability to obtain the information from the environment in which it is embedded and utilize it to dynamically build models of computing. The process is reciprocal: the environment can and should also become "intelligent" in that it also has a capability to detect other computing devices entering it. To provide the needed data input a distributed, "embedded plug and play" networked sensor system is incorporated into the concept to achieve and more complete solution. The development of this set of interconnected technologies would have the same effect, reduced staffing with increased operational efficiency and effectiveness. This set of technologies could be applied to almost any complex industrial or commercial process witht the same positive impact on the bottom line, reduced costs through personnel cost reductions.

Title:Spot Cooling Mini-Loop Heat Pipes
Abstract:TA&T, in collaboration with Swales Aerospace, proposes to develop a novel modular, spot-cooling (two-phase) miniature loop heat pipe (mini-LHP) thermal transport system consisting of distributed flat-plate ceramic evaporator modules tied to a central condenser system. The use of a two-phase mini-LHP thermal transport system represents a zero-noise/zero power thermal solution for cooling COTS electronic components/computers in a high temperature environment. The modular approach will allow flexible expansion or contraction of the system capacity without significant system redesign. This approach will allow retrofitting of existing electronics with the compact ceramic evaporators with only minor modification to the component housing. For new electronic components, the approach will allow integration of the evaporator modules during printed circuit board assembly for the optimum packaging efficiency. The Phase I effort will assess the electronic systems in need of cooling and design a loop heat pipe system based on the thermal requirements of those components. The feasibility of fabricating the novel ceramic evaporators will also be demonstrated and testing will be performed to verify performance. This work will serve as the basis for Phase II in which a complete prototype system will be fabricated and tested. The proposed approach will have high applicability to a variety of DOD, NASA and consumer electronics where compact, reliable, zero-power cooling is required. Primary consumer applications will be in laptop as well as desktop computers.

Title:Low Cost Non-Explosive Shock Qualification Testing
Abstract:We propose to development of a relatively low cost, flexible, and environmentally sensitive means for shock qualification testing major shipboard systems using a non-explosive energetic source to generate the dynamic time-history environment representative of UNDEX situations. The key aspects of this system are 1) elimination of the use of energetic sources with a DoD Hazard/Classification 1.1, 1.2 or 1.3 materials that require handling by qualified EOD personnel plus storage under Quantity Distance (Q-D) requirements; 2) Portability to a variety of locations/environments; and 3) causes a minimizes the impact on the environment.The proposed method utilizes combustible gases (e. g., acetylene) under high pressure conditions and forced to detonate by a "hard" ignition source. In addition, geometric shields are configured to direct shock and tailor resulting cavitations and late-time bubble formation to be representative of known UNDEX consequences.Phase I will be conducted using a proven approach combining CFD modeling with table-top scale experiments to show the feasibility of the proposed system. The system to be developed here will have immediate application in various commercial industries. Qualification of ships and shipboard systems under a variety of extreme environmental conditions (storm generated waves, vessel impact, etc.) is an immediate application. Further, the system can be modified to address other offshore and dockside facilities such as petroleum rigs, floating production and refining ships, nuclear plant facilities, and sub-sea pipelines.

Title:Development of a Non-Explosive Ship Shock Testing System
Abstract:Presently, at-sea ship shock tests subject the vessel to high-pressure pulses created by detonating large explosive charges in the open ocean. The process is highly disturbing to the environment and subject to a variety of operational restrictions. The results are severe costs and scheduling constraints. Legal challenges due to increasing environmental concerns are driving costs upward and may potentially prevent the Navy from performing this vital testing. DYNAFLOW INC., teamed with APTI and Anteon Corporation proposes to leverage previous research efforts to develop a completely non-explosive technology that will enable `in-situ' shock testing in an enclosed facility such as a dry-dock or wet slip. This technology can also be applied to an open water near shore environment through the use of appropriate pressure mitigation techniques. The concept, "DockShock", involves employing an array of proprietary electrically initiated pressure sources that produce pressure pulses sufficient for full ship shock testing. Because these pulses are directed, only a small fraction of the open ocean energy is necessary to deliver the equivalent shock impulse. Consequently, an enclosed facility can be modified with protective measures to insure that the dock or surrounding structures are not damaged. The benefits include: ˙ Environmental - eliminates unnecessary damage to ocean wildlife. ˙ Cost - substantial savings achieved by eliminating at sea costs and time. ˙ Flexibility - testing schedule no longer driven by weather and seasons.

Title:Low Cost Non-Explosive Shock Qualification Testing
Abstract:The non-explosive shock testing of naval vessels and shipboard equipment project rapidly integrates a COTS technology currently used in commercial oil exploration, tailors the technology to meet Navy's LFT&E technical and environmental challenges, and provides the resulting package to the US Navy. The project provides a process and system by which the US Navy can avoid the severe environmental problems that have plagued naval shock testing in recent years. The process is safer and environmental benefits are significant compared to testing naval vessels and shipboard equipment with shocks generated by explosives. Seabed disturbance is minimal, fish kill is virtually eradicated, there are no chemical by-products and no residues are left at the test location. The absence of explosives means that shock testing can be carried out in virtually any location. This saves time occupying a warship on transit to a range. It also means testing is no longer dependent on range availability and a faster turnaround time between tests means better use of test dollars. The resulting capability will support the US Navy by providing a low cost, environmentally benign approach to developing necessary test data insuring reliability shipboard systems subjected to underwater shock loads. The Navy currently lacks a cost effective, environmentally sound approach to generate test data for qualification of ships, submarines and shipboard equipment for shock, vibration and LFT&E requirements. The resulting capability will support the US Navy by providing a low cost, environmentally benign approach to developing necessary test data insuring reliability shipboard systems subjected to underwater shock loads. The proposed system will also be useful in crew training scenarios as it can provide multiple underwater shock loadings to ships during training exercises. This is especially important in reduced manning environments that are responsible for much of the cost savings in naval surface combatants of the future.

Title:Failure Mode Maps for Marine Composite Structures Subjected to Blast and Ballistic Impact
Abstract:A methodology for determining the failure mode and failure conditions of marine composite structures subjected to blast and ballistic impact will be developed. Analytical expressions characterizing the various failure modes will be derived. These expressions will include the effects of ballistic damage. Using these expressions failure mode maps will be generated. These maps will allow Navy ship designers to quickly and easily assess the failure modes and failure conditions of marine composite structures subjected to blast and ballistic impact. This research and the resulting analysis tool will expedite the implementation of composite structures in Navy ships by allowing the blast and ballistic resistance of these structures to be quickly and easily assessed. It also provides a framework for development of cost-effective test programs and interpretation of the test results.

Title:Blast and Ballistic Response of Advanced Composite Structures
Abstract:KCI will develop a dynamic, nonlinear FEA methodology for evaluation and/or optimization of marine composite structures subjected to conventional weapon external and internal blast and ballistic threats. LS-DYNA3D will be extended via user defined material models. Phase I will concentrate on sandwich panel structures, stiffened sandwich panels, and joining sandwich panels. The KCI team has years of experience in design, optimization, and construction of stiffened composite sandwich panel structures for use in blast-hardened military C3I shelters. Important aspects of the analysis methodology are the elements and material models used for accurately and efficiently representing deformation and damage in composite face sheets, core, and structural connections. Practical models used must employ parameters whose values are readily available or easily measured. A test program for supplying these parameters will be proposed. Initial development of FEA methodology will use prototypical blast and impact validation problems, designed to exhibit significant damage modes, such as face sheet tensile, compressive, or wrinkling failures, core shear/compression failure, delamination, panel buckling, and failure of structural connections. A set of guidelines for accurate and efficient analysis of marine composite sandwich structures will be developed. Key to this effort is an understanding of the needs of the designer. In addition to serving the specific needs expressed in the solicitation, KCI anticipates that the developed finite element analysis methodology will be applicable to the design and optimization of a wide variety of other military and civilian systems. For example, terrorist threats have provided motivation to evaluate new and existing structures for their ability to withstand blast and/or ballistic impact loading. The modeling methods developed and demonstrated in the proposed software development and demonstration will allow designers to more accurately and efficiently capture the failure mechanisms that are unique to composite sandwich structure.

This tool will have direct applicability in the design of marine composite structures with enhanced survivability under blast/ballistic threats. Previous research work performed at Materials Sciences Corporation (MSC) has successfully demonstrated the integration of advanced composite progressive failure models into LS-DYNA for accurate prediction of deformation and failure of various composite structures subjected to ballistic and blast impacts. The approach proposed herein will leverage this simulation data as a foundation to guide the development of robust material/structural element models for assessing the blast/ballistic performance of marine composite structural components. Simple ballistic and blast structural element models will be developed to efficiently capture composite structural failure modes and dynamic damage propagation for composite structures subjected to fragment impact and blast loading. The developed material models will be critically evaluated and calibrated by correlating with simulation results as well test data provided by the Navy. This program will develop a design tool that has direct insertion potential for all Defense contractors (Navy, Army, and aerospace) for survivability design of various composite structures. Application will include both military and civil markets such as aircraft, armored vehicles, surface marine craft and submarines and blast resistant structures.

Title:Thermo-Electric-Powered Thin Film Evaporators For Cooling Power Electronics
Abstract:We propose developing "spot cooling" devices for the high heat flux electronic components in the Navy's shipboard electronic cabinets. Our spot cooling devices will incorporate a combination of thin film evaporators and thermo-electric power generators. Our thin film evaporators are expected to achieve the high heat removal capacities that will be required for new Integrated Power Systems (IPS), electromagnetic weapons (EMW), and high power radar electronics. The thermo-electric power generators will be used to power locally the thin film evaporators and the micropumps that may be required to return the thermal fluid to the evaporators. This local utilization of the power from a thermo-electric device maximizes the advantage of incorporating such devices in a thermal management system. Our complete cooling system will drastically reduce the waste heat that is entering the air-space of the cabinets, remove heat at a sufficient temperature to allow its removal from the working fluid via compact cooling water heat exchangers mounted on the outside of the cabinets, and maintain the electronic components at a reduced temperature despite their high heat fluxes, which will increase their reliability. Our thin-film evaporators will be able to remove a large amount of heat from high power electronics, so these electronic components (power modules, radar T/R modules, and solid-state lasers) will operate at a reduced temperature, which will increase their reliability. Our use of a two-phase working fluid system will allow the efficient removal of this heat from the electronic cabinets that house these components. One of the benefits of our thin film evaporator technology is that it reduces the size of the overall cooling system, since it requires only a fraction of the amount of fluid used in spray or jet cooling systems and fewer ancillary components. Analogous cabinet cooling systems with "spot cooling" thin film evaporators mounted on the major high-heat flux components could be designed for commercial electronic equipment, such as rack-mounted network servers in data centers. ATEC is currently working on developing a potentially high volume electronic cooling product utilizing our thin-film evaporator technology.

Title:Chiller for Direct Conversion of Waste Heat to Cooling for Power Electronics
Abstract:The Navy needs Advanced Thermal Management technologies to remove high heat fluxes from power electronics, and Waste Heat Conversion technologies to use the removed heat for space cooling on Navy ships. We propose to develop a system that converts the waste heat into space cooling directly (our system requires no intermediate conversion of heat into electricity). We propose to develop: (1) an Impingement Evaporator, which will remove high heat fluxes from power electronics; and (2) an Absorption Chiller, which will directly use the removed heat for space cooling. This proposal focuses on development of the Absorption Chiller. In Phase I, we will design, build, and test a breadboard Absorption Chiller that converts 3kW of heat from vapor below 125 C into chilling power. The Phase I work will involve selecting non-hazardous fluids that can be used in an absorption chiller driven by vapor below 125 C. We will also analyze costs for fleet insertion. In Phase II, we will: (1) optimize the design of our Absorption Chiller (consistent with Navy performance standards); (2) build the optimized Absorption Chiller; and (3) test the Absorption Chiller with a 250 kW prototype power module that generates approximately 3 kW of waste heat. In Phase III, we will build and sell our Absorption Chiller for many Navy ship-based and land-based applications, as well as private-sector applications. Our Advanced Thermal Management + Waste Heat Conversion system (which includes our Absorption Chiller) will benefit a wide range of applications in the federal government and the private sector. Promising markets include power electronics; computers (ranging in size from mainframes to laptop PCs); cogeneration systems; and simultaneous cooling of high-heat-flux components and cabin cooling or heating in automobiles and commercial aircraft.

Title:Gas Cycle Micro Device for Conversion of Waste Heat to Electrical Energy
Abstract:A micro device designed for low cost mass production and replication for system level applications is proposed for converting waste heat to electricity. The device operation is based on fundamental gas thermodynamics, and leverages MEMS/microsystem fabrication technology to achieve high efficiency conversion in a footprint compatible with electronic packaging. The proposed concept provides both thermal management of electronic systems, and auxiliary power from waste heat. The resulting electrical power can be conditioned and used as a DC power source; or can be used to charge a battery, fuel cell, or similar electrical energy storage device. An efficient technology for achieving the conversion of heat to electric energy for electronic systems will have broad application, ranging from power electronics to a host of other electronic applications in both commercial and military markets. The proposed concept would augment power sources for systems as varied as all-electric military ships and aircraft to portable electronic devices. State-of-the art competing technologies suffer from low efficiency and/or the inability to be effectively integrated at the electronic system level.

Title:Nanowire Heat Pipes for Electronics Thermal Management
Abstract:A nanostructured materials heat pipe technology is proposed. The high capillary pressure and moderate flow resistance predicted for the proposed nanowire wick material makes it ideally suited for high heat flux (> 300 W/cm2) applications. The nanowire wick is created using cost-effective chemical manufacturing techniques suitable for large-scale manufacture. The process will enable thin profile devices to be built that can be directly incorporated into electronic device packages, eliminating the thermal barrier presented by conventional packaging materials. The Phase I project will determine the suitability of nanowire heat pipe wicks for high heat flux applications by building copper nanowire arrays on copper substrates and testing the ability of the wick to remove heat fluxes up to 1000 W/cm2 using water as a working fluid. The Phase II project will construct complete heat pipe devices and demonstrate effective thermal management of power electronics systems. Successful demonstration of a nanowire wick heat pipe capable of removing high heat fluxes will enable effective thermal management of next generation of high power density microprocessors for portable applications, laser diode arrays in communications systems and power thryistors for power conditioning. The nanowire heat pipes are an enabling technology that can effectively remove heat from within the electronics package and enable system size to shrink while performance continues to increase.

Title:Nanocrystalline Materials to improve Thermoconductivity of Heat Pipes
Abstract:The solid state power conversion inherent in the Navy's Integrated Power System (IPS) produces heat loads beyond those in today's shipboard electrical distribution systems. The introduction of additional high power systems such as electromagnetic weapons (EMW) and high power radar, together with the heat loads associated with the IPS, will produce heat loads in working spaces approximately 700% greater than those of DDG 51 class ships. In large part, the waste heat is generated in the power semiconductors contained in the power electronics components whose power densities will eventually surpass 1000 W/cm2. Through the development of an advanced coolant with enhanced conductivity and an integrated suspension of phase-change particles, combined with the use of a high performance packaging material, k technology Corporation and Primet Precision MaterialsO propose to develop a solution compatible with current systems and procedures. Through the fabrication and evaluation of a demonstration system, the team will characterize the performance gains. Evaluation materials will also be manufactured and evaluated for thermal conductivity, mass density, and flow characteristics. Heat pipes work on the concept of having a fluid absorb heat through vaporization and then transfer it by condensation to a heat sink. These traditional heat pipes are effective, however they are limited by how much heat the working fluid can carry. Heat pipes using nano-technology phase change fluids combined with the high conductivity composite material k-CoreTM can transport many times the amount of heat as current techniques. In addition, these materials are compatible with current packaging formats. The combined nano-fluid and high conductivity materials represent an enabling technology for high power electronics imperative for the Integrated Power Systems required for emerging naval electric drive systems and electromagnetic launch and recovery systems.

Title:Fabrication of High Conductivity Heat Pipes using Multi-Walled Carbon Nanotubes
Abstract:This proposal will demonstrate the development of a composite material containing aligned carbon nanotubes with thermal conductivity far in excess of traditional copper or aluminum. A unique process for easily fabricating the aligned carbon nanotubes will be demonstrated in Phase I. This aligned Carbon Nanotube Composite (CNC) will be fabricated into a heat pipe in Phase I and demonstrated. In addition to the potential for a thermal conductivity that approaches graphite (6600 W/mK, compared to 390 W/mK for copper), the CNC heat pipe is ideal for direct chemical bonding to solid-state electronic devices, thereby eliminating interfacial thermal resistance. While existing hardware is limited to cooling heat fluxes of approximately 100 W/cm2, Mainstream has already demonstrated that technology exists to push this capability to 1,000 W/cm2 using microchannels or spray cooling, however heat pipe systems would be clearly simpler and more reliable. This Phase I effort will demonstrate the potential for a high heat flux, heat spreading, heat pipe to transfer waste heat generated in the semiconductor junction to a secondary cooling source such as sea water, while maintaining a low junction temperature. Phase I will demonstrate a high thermal conductivity composite composed of aligned carbon nanotubes with enhanced thermal conductivity. Phase I will demonstrate the capability of this heat pipe to remove heat fluxes in excess of 300 W/cm2. Phase I will include manufacturing techniques, design specifications, experimental data and cost analysis. This effort will experimentally demonstrate the performance of a simple but innovative high performance heat pipe with heat flux capability that far exceeds traditional copper or aluminum heat pipes. The proposed material would be applicable to all types of heat pipes and compatible with essentially all working fluids. In addition to the Navy applications, other potential applications include passive small-satellite thermal control, hardened radiator systems, and commercial or military electronics cooling (high-power electronics, supercomputers, electronic switch gear, and avionics ). Mainstream has performed a commercialization study and the commercial potential is tremendous.

Title:High Performance Heat Spreaders for High Heat Flux Power Electronic Modules
Abstract:The proposed Navy SBIR program will develop a high performance heat spreader technology that can be integrated into power semiconductor die packages to acquire and spread high heat fluxes exceeding 1,000W/cm2. The heat spreader will also interface with other parts of the thermal management system to effectively transport and dissipate the large heat loads to maintain the safe operating temperature of the semiconductor. The Phase I objective is to verify the feasibility of integrating the proposed concept in a shipboard environment. Design feasibility studies will be performed to assess the system benefits of the proposed integration schemes and generate feasible component designs for the Phase II prototype demonstration. The Phase I results will bring the proposed concept to the DOD defined Technology Readiness Level (TRL) 3: Characteristic proof of concept. The Phase II program will focus on upgrading the technology to TRL 6 (prototype demonstration in a relevant environment) by integrating and testing a prototype heat spreader in a 250kWe power module. The follow-on Phase III program will further upgrade the technology to TRL 8 (actual system completed and qualified through test and demonstration) through full-scale integration and testing under actual conditions. While the proposal focuses on thermal management of solid state power conversion modules, the proposed heat spreader technology are also applicable to other military high heat flux applications such as solid state diode lasers, a critical technology for Directed Energy Weapons and High Power Radars. In addition to military and aerospace applications, there are numerous commercial applications for the proposed technology, including cooling of high-end workstations and servers, power electronics for electric and hybrid vehicles, and optoelectronics such as laser diodes for telecommunication. These markets are synergistic in that technical development in one aid all, and commercial progress in one will increase the production base and reduce unit costs for all. The technology developed through this Navy SBIR program will provide the market with a higher performance alternative to the existing heat spreading technologies and products (e.g. vapor chamber heat pipes, diamond spreaders, and high-conductivity interface and composite materials).

Title:Two-Phase, Vibration-Induced Droplet Atomization (VIDA) Thermal Management of High Heat Flux Power Electronic Modules
Abstract:Vibration-Induced Droplet Atomization, or VIDA, is a thin-film spray cooling technology developed at Georgia Tech with tremendous potential for the thermal management of Power Conversion Modules for Configurable Zonal Systems (CZS). The patented VIDA technique uses a vibrating piezo driver in a self-contained cell to deliver a highly controllable, rapid-response, on-demand aerosol-sized water spray to hot electronic components. Vapor evaporated from the hot surface condenses on a secondary cooling loop, thus enabling efficient heat removal. Results show that a small charge can effectively manage high power densities with an extremely low ratio of power consumed to power removed and with very low flow rates. Through use of a small piezo pump, the system can be made orientation-independent. Cooling rates in excess of 100W/cm2 have been measured while keeping devices below 125C. It is anticipated the technique can be developed to deliver up to 1000 W/cm2 with optimizations described herein. The VIDA technology has the potential for delivering a method of high power-density thermal management in a relatively simple, low-cost configuration, in a low-profile form factor. Applications include cooling of military electronics, including lasers and radar components; high-power rack mount and blade servers and high-temperature "under-the-hood electronics."

Title:High Heat Flux Cooling of Power Electronics
Abstract:This Small Business Innovation Research project addresses the development of high heat flux thermal management technology for cooling solid-state power conversion devices on board Navy ships. It is anticipated that the drive towards smaller electronic components and faster switching speeds will require a cooling technology that can dissipate in excess of 1,000 W/cm2 while maintaining junction temperatures below 125 °C. We propose to develop a liquid cooled heat sink that has the potential to achieve a thermal resistance of 0.03 K/(W/cm2). This heat sink could provide cooling at 1,000 W/cm2 with only a 30 °C approach temperature difference, leaving substantial temperature margin for the internal resistance of the electronic device and the heat transfer to the zonal heat exchanger. We have experimentally demonstrated, to date, a thermal resistance of 0.075 K/(W/cm2) using this heat sink technology. Design calculations indicate that it is feasible to further reduce the thermal resistance by a factor of two or more. In Phase I we will design, fabricate, and test a 1 cm2 heat sink to demonstrate the feasibility and performance potential of the proposed cooling technology. We will also develop, in collaboration with the Navy, a preliminary design of a full-scale prototype to be developed and demonstrated in Phase II. The proposed heat sink technology would have widespread application in the rapidly growing market of high power, solid-state energy conversion systems. In parallel with the Navy's drive towards a more electric ship, the Air Force is also engaged in similar effort. Civilian applications include power conditioning for industrial equipment, electric drives in rail systems, and in hybrid drive automobiles, to name a few. Other applications, such as, solid-state power lasers and high-end microprocessors, would also benefit from improved high heat flux cooling technology.

Title:Development of an Innovative Active Cooling System for High Heat Flux Electronics
Abstract:Many military electronic applications require cooling that is beyond the capabilities of both passive and active conventional cooling techniques. A need exists for cooling technologies that can reach and exceed 1000 W/cm2. Recently, direct spray cooling has been investigated as a means to remove high heat fluxes from electronic chips. In this approach the coolant, water or dielectric fluid, directly impinges upon the surface of the electronic chips and rapidly vaporizes to remove heat. However, direct spray cooling of a chip has severe disadvantages. In this program we will investigate a novel approach to electronic chip cooling that will allow heat flux removal rates of 1000W/cm2 and beyond, using a system that is easier to implement and less complicated than direct spray cooling of the chip surface. Spray cooling will be accomplished on the backside of an advanced heat spreader in a completely self contained system that is separate from the electronics, which will be relatively simple to attach to an electronic chip. A high performance thermal interface material will be utilized to minimize the interface resistance between the advanced cooling system and heat generating chip. The cooling system concepts developed in this program may be useful for numerous military and commercial packaging applications where devices are thermally constrained, and conventional cooling techniques are inadequate. Potential applications include radar T/R modules, power conditioning electronics, commercial and military hybrid electric vehicles, high power laser diodes, and military pulsed power systems.

Title:Low Cost Composite Reconfigurable Stern Launch/Recovery System
Abstract:KaZaK Composites will conduct design, materials, manufacturing, and experimental studies supporting the eventual production of a reconfigurable stern ramp that allows a single system to be quickly and automatically adapted to launch and recovery of an extremely wide range of vessels. KCI's composite material design will be optimized for low cost production using pultrusion-based processing technology. Research will extend and apply KCI's work with a unique flexible macro-composites composite laminate architecture and active control of ramp end depth. KCI will work closely with Bath Iron Works to ensure that the system solution evolved during Phase I and II is compatible with demanding and diverse needs associated with Naval operations in Sea State 5. Phase I work falls into five general categories: 1) Development of alternative system design concepts meeting weight, cost and performance requirements, 2) Identification of composite materials compatible with goals for cost, structural requirements and low cost production, 3) Design refinement and verification using 3D CAD and finite element analysis, 4) Fabrication and testing macro-composite samples to measure relative axial and torsional stiffness and demonstrate reconfigurability, and 5) Projection of cost and weight of the proposed RO/RO ramp system. A wide variety of commercial and military vessels launch and recover smaller utility and support craft. Once proven in this SBIR, the technology to be developed here should be generally applicable to a very wide range of situations. Initial sales will probably be to military vessels. However, there will also be a market with commercial fishing and other working vessels, as well as pleasure craft. A rapidly reconfigurable ramp could also serve as a defensive "drawbridge" to help secure buildings and other facilities from terrorist assaults by automatically changing shape of an entrance ramp to prevent vehicle passage, or even trap unapproved vehicles.

Title:Robust Open Systems Architecture Surface and Underwater Vehicles Stern Launch/Recovery System
Abstract:Conventional Launch and Recovery systems do not function automatically, at high ship speeds and in moderate sea states. The proposed system utilizes a unique concept of a deployable, largely open, flexible, "belt" conveyor ramp that can operate through and below the water surface in the wake of the ship with minimal drag. The open belt will allow both manned and unmanned, surface and subsurface craft to drive onto the moving conveyor with a soft landing and be transported up the sloping conveyor system out of the water and onto the cargo deck. The "belt" material and degree of tension to be utilized will affect the softness of the landing, the automatic centering and the traction for hauling the vehicle from the water. No special adaptations should be required for the various vessel types being launched and recovered. The powered conveyor ramp slope control will allow partially lifting the vehicle once it has landed on the moving surface, reducing the slope of the ramp. Projections from the vehicles, if any, will catch in the belt to provide more positive hauling forces. The hauling process can be readily reversed to launch vehicles of any size within the weight capability of the system. A robust yet simple launch and recovery system will be of great use for the deployment and retrieval of special forces craft in adverse sea states and at higher speeds than now possible, thus increasing safety and mission effectiveness. Additional users of this technology will include research vehicle teams, the off shore industry and salvage operators that have a need to safely deploy and recover surface craft in moderate sea states. The system can also be used to retrieve disabled surface(d) vehicles divers/seals and man overboard-downed pilots by backing the host ship to the vehicle or person and then hauling it/them on the moving conveyor surface. The combination of a "soft landing" and use at moderate ship speeds, in principle to greater than 20 knots, should make this relatively simple concept just what the Navy and marine industry currently need to safely launch and recover a diverse range of vehicles with minimal manning requirements.

Title:A Hybrid Robotic Vehicle and Mechanized Stowage System for OOVs
Abstract:Intelligent Auotmation, Inc. (IAI) proposes to design an integrated OOV handling system consisting of robotic transport vehicle and a mechanized stowage system. For the transporter, we will evaluate a design for a Hybrid Hexapod Robotic Vehicle (HHRV) for use as a heavy-lift, stable, reconfigurable, omni directional, transport mechanism. The HHRV is a hybrid vehicle integrating features of both wheeled and legged mechanisms. It offers the ability to lift legs and step over obstacles. The concept proposed offers maneuverability in confined spaces both above and possibly below deck. It also offers lifting and positioning capability to present and retrieve OOVs to the launch and storage systems. The orientation capability also assists with loading and unloading. The OOV could also carry a manipulator arm to perform automated load/unloading. We also propose the use of a mechanized stowage system consisting of horizontal and vertical elevators of custom design to accommodate OOVs of varying size and shape. In Phase I, we will address the issues related to movement of OOVs through the ship, storage of OOVs within ship, and electronic tracking of OOVs. Each of these issues is central to the long-term objective of autonomous launch, retrieval, and storage. Mobile robot sales are expected to soar from $665 million in the year 2001 to more than $17 billion by 2005. The applications in which growth for mobile robots is expected include: space, industrial service, medical and healthcare, transportation (automotive), agricultural, construction, mining, household service, educational, toys and entertainment.

Title:Trackless, Vacuum Secured Organic Offboard Vehicle Handling System
Abstract:The Navy is rapidly committing to widespread use of unmanned vehicles to provide critical functions in support of fleet operations. These offboard organic vehicles (OOV) include air, surface and undersea-unmanned vehicles. Current systems for onboard handling of these vehicles are labor intensive and require disparate pieces of equipment. KCI, working with Bath Iron Works, proposes to design and build a new OOV handling system that provides for movement of OOVs from stowage to launch area, and then automates returning it to stowage upon mission completion. The key to this system is a modular transporter system that is self-guiding and self-securing using vacuum technology. The transporter cart will be made from a combination of stainless steel and pultruded composite structural elements fabricated by KCI. We will draw heavily on experience gained in the design and fabrication of a similar multifunctional computer-vision, vacuum secured system for the Air Force. In Phase I KCI will conceive and iterate various system alternatives, compare them with our baseline, and discuss the best of the alternatives with the Navy. We will also develop test methods, fabricate test specimens and perform experimental studies to validate the performance of key components of the handling system. KCI's proposed solution for an OOV handling system makes use of an autonomous or semi-autonomous modular approach to ensure flexibility in meeting current and future OOV handling requirements at minimal cost, minimal ship impact and significantly reduced program risk. The successful demonstration and acceptance of autonomous vehicles with the capabilities proposed for this Naval SBIR application are generically applicable to a wide range of future military and civilian applications. For example, with the same guidance technology, vehicles could be used to automate the delivery of critical supplies to troops operating in a hostile military environment. Commercial adaptations could be used to move warehoused items, reducing manpower needs associated with shipping and handling.

Title:Compact and Intelligent Robotic System
Abstract:Physical Optics Corporation (POC) proposes to develop an innovative, affordable compact and intelligent robotic system with an open system architecture for automated shipboard handling and stowage of organic offboard vehicles on DD(X) and other U.S. Navy ships. The proposed Compact and Intelligent Robotic System (CIROS) will minimize damage to ships and injury to crew by bringing the intelligence-programming the robot with planning and operation sequence algorithms, dexterity-dual-arm robotic operation, and performance-optimizing operation sequences to current and future robotics technologies. CIROS offers a major innovation in robotics, fast and efficient inverse kinematics for a high-degree-of-freedom manipulator and collision detection and avoidance for manipulator operation. POC's innovative real-time inverse kinematics, with broad applicability across the field of robotics, will bring the safest and the most flexible robotic operation to a shipboard environment, and our proprietary collision detection and avoidance algorithm for operation of manipulators will bring the safest and the fastest manipulator operations to at-sea operation. The CIROS will be a universal autonomous robot that can handle many types and shapes of objects, and will be reconfigurable for other applications such as weapon handling, manned aircraft handling, and material transfer in addition to organic offboard vehicle handling. POC's proposed CIROS will strongly benefit many commercial operations, including factory automation, hazardous area assessment such as in nuclear power plants and under sea, and robotic surgery. It will also advance shipping and stowing functions performed at shipping companies such as UPS and FedEx, as well as factory automation for operations not normally performed by robots such as safety inspections and flexible assembly line operations.

Title:Advanced Ship/Fixed-wing UAV Recovery Interface
Abstract:The Leaning Airbeam Shipboard Arrestment System (LASARST) is a radically different type of UAV recovery system for shipboard and unprepared land based operations. Although LASARST can also be used with LPD class vessels and small land based recovery areas, it is designed specifically for those vessels that have too small a deck area to capture the UAV in the `conventional' or current method (i.e. SPARS). Where it differs radically from the present system is that it provides a much greater area of capture with a greatly reduced footprint from the present SPARS and is automatically self deploying. Therefore it can be mounted on much smaller vessels and can yet capture UAVs that at present are not considered possible solutions to Naval and Marine Operations. LASARS can open up UAV operations to vessels such as DDG Class Guided Missile Destroyers (66ft Beam width) and FFG Class Frigates (45ft Beam width) which presently have insufficient beam width at the aft end for SPARS recovery of a 450-500lb UAV landing at speeds up to 70mph. At the completion of Phase I, airBeams LLC will have a preliminary system design and model completed of a conceptual LASARSTM. In Phase II airBeams LLC will refine the design and model to a point where it can be utilized as the basis for a model LASARST for testing. The prime commercialization prospect is the UAV user community (DOD, DEA, INS, Department of Homeland Security, etc.) in particular the US DOD. UAVs are now being used for many civilian applications from photography to seismic soundings for oil companies. Most usually, the latter in particular, operate with small drones from rough territory or from the sea and they do not have the luxury of LPD Class vessels on which to land the UAV. The potential commercial market will expand considerably as the sophistication and reliability of the UAVs is improved because of the military requirements. This will drive down costs, increasing the potential market for LASARST.

Title:UAV Recovery System
Abstract:Navy surface combatants will employ more unmanned autonomous vehicles in future operations. In addition future ships (DD(X), CG(X), and LCS) will be designed for reduced manning thus future Unmanned Aerial Vehicles (UAV) recovery systems must be unmanned or at least minimally manned. The majority of existing and projected future UAVs are fixed-wing aircraft with no capability for vertical launch and recovery. There are currently no safe and accurate methods for ship board recovery of fixed-wing UAVs. The Navy has the need for a lightweight inexpensive automated system for recovering and securing multiple types of fixed wing UAVs. These devices should require minimal manpower requirements and should be capable of operating in sea states 4 and 5. A phase I program is proposed to develop recovery system which utilizes a Homing system to guide the UAV into a Docking system which will capture the UAV, decelerate the UAV to a stop and then secure the UAV to the deck. A conceptual system design will be developed in Phase I, a prototype developed in phase II and shipboard evaluation will be completed in Phase III. The proposed homing system has could be used to guide any vehicle to the docking station. (P-030217) The successful development of the proposed recovery system will provide the Navy with UAV recovery system that will accommodate a variety of fixed wing aircraft. The system will capture, decelerate and secure the UAV with a minimum of ship's force. Features of the docking station will be adaptable to rotary winged air craft as well. The homing system will be able to guide any UAV, UUV, USV or a manned vehicle to the ship.

Title:An Autonomous Fixed-Wing UAV Shipboard Recovery System
Abstract:Among the many autonomous guidance and control challenges facing DoD and industry today is the safe, reliable shipboard recovery of fixed wing UAVs. Leveraging our autonomous landing research conducted for the Air Force Research Laboratory, Geneva Aerospace proposes an autonomous shipboard recovery solution using a hybrid control system structure that combines trajectory synthesis guidance with line-of-sight rate guidance to provide precision control to recovery using an integrated GPS aided relative navigation solution. Employing the principals of terminal homing guidance, the design is ideally suited to facilitate recovery on a moving ship deck. The concept will take advantage of the precision positioning offered by the relative navigation solution and precision path regulation offered by the hybrid control system to capture the UAV via a mechanically simple cable arresting system, enabling recovery on very small deck platforms. We will demonstrate that the recent technology advances in miniaturized GPS receivers, micro-electromechanical sensors (MEMS), spread-spectrum communications transceivers, and single-board computers all combine to offer a small, light-weight, robust, and affordable hardware architecture to address the shipboard recovery problem. When integrated with the proposed guidance, navigation, and control software, this hardware architecture will provide an excellent integrated system solution with a very small logistics footprint. According to the Office of the Secretary of Defense (OSD) UAV roadmap, the US DoD will invest over $4 billion in UAVs over the next decade. This will include a substantial investment in autonomous control systems technologies that significantly enhance the operational utility of UAVs by allowing a few, or even a single, operator(s) with minimal training to effectively manage and control groups of vehicles. The introduction of a lightweight, safe, and robust precision shipboard recovery system for fixed wing UAVs will provide a much needed capability that will enable the US maritime forces to take advantage of the many systems that will be introduced over the next decade. Proven, reliable autonomous landing technologies could also benefit the general aviation industry.

Title:Simplified, Low Cost, Fixed Wing Unmanned Aerial Vehicle (FWUAV) Recovery System
Abstract:KaZaK Composites Incorporated and our program partner Bath Iron Works propose to design and develop a simple, easily deployable and stowable system for capturing UAVs in flight and returning them to a ship. The proposed system features an innovative capture mechanism, and provides the following features and benefits: " Safety of personnel, ship and FWUAV are inherent in the design. " Little weight increase to the aircraft. " Aircraft deceleration g-loads are low. " Composite capture system is lightweight, easily moveable, and corrosion resistant. " System length allows it to store in part of a 20-foot ISO container for shipping. " Transport of the composite capture system requires only one person. " Interchangeability between FWUAV's is inherent in the proposed design. " Interchangeability between ship classes is also inherent in the proposed design. " Entire system is exceedingly simple, maintainable, repairable and operator friendly. " Minimal impact on the FWUAV. " Navy environment will not adversely impact structural components in the system. In Phase I KCI will develop a complete system design, project costs and perform lab tests of key features of the proposed system, including the basic capture mechanism. A likely commercialization path would include a Phase III purchase of a quantity of capture systems by the Navy for sea trials. Other applications for the simple, low cost capture system will develop both in DoD and the commercial UAV market once the Navy certifies the acceptability of the system for use on Naval vessels. In the Armed Services alone, the market for capture systems is significant. With increasing use of UAV's in all aspects of warfare, viable capture systems that are easily deployed in a variety of harsh environments and restricted locations will be required. The commercial market for UAV's is growing. Operators of these systems will also be potential customers for KCI's small platform UAV capture systems.

Title:Ship Motion Effects on Human Performance
Abstract:The Navy need is for design specifications and guidelines which interrelate ship hull form characteristics and onboard human performance in a motion environment. These specifications and guidelines will prevent those motion profiles that exceed human limits for acceptable human performance and safety and must be based on empirical evidence obtained from a ship motion simulator or actual ships. The product of this research will be: (1) specifications of six degree of freedom motions and accelerations that produce degradation of human performance and safety to the point of being unacceptable; (2) the design rules and/or tools to be implemented for other hull types/motion effects to reduce the incidence and impact of performance degradations; (3) guidelines for evaluation of human performance capability and safety in a ship motion environment; and (4) descriptions of new methods to characterize ship motion effects on human performance and safety. The proposed effort will be conducted by Carlow International, a human systems integration research organization, supported by the National Biodynamics Laboratory (NBDL) of the University of New Orleans, a leader in the analysis and research on effects of ship motion on human performance, safety, and quality of life. NBDL has the ship motion simulators that are required to generate data on the effects of specific hull forms on human performance and safety. This effort will provide empirical data on the impact of ship motions associated with ship hull forms on human performance, safety and quality of life. The tool produced in the project will support identification of the effects of ship motion on human performance capability as a function of sea state and tasks to be performed. Potential commercial applications include applications to mitigate the effects of platform motion on human performance for commercial ships, including cruise ships and ferries, maritime and offshore systems, aircraft, both fixed and rotary wing, and virtual environments.

Title:Ship Motion Effects on Human Performance
Abstract:The somatosensory disturbances that cause motion sickness result in degradations of cognition, alertness, mood and motivation. We propose to empirically quantify the duration and extent of these effects and to describe them in a mathematical algorithm. A discrete event simulation tool (Micro Saint) will be used to model the human activity associated with a ship undergoing maneuvers at various speeds, in various sea states over several days. The model will include a range of motion sickness profiles induced by a standard set of ship motion and hull designs estimated from existing data on whole body vibrations through 6 degrees of freedom. The motion sickness algorithm will then be used to degrade the response time and error rate of the simulated crew in accordance with these ranges. Model driven effects on workload and crew effectiveness will then be used to compare a variety of hull designs. The adequacy of the standard hull motion curves for predicting motion sickness will be assessed in Phase I. Phase II will be used to validate the ability of the Micro Saint ship model and the motion sickness algorithm to reliably predict at sea human degradation. The development of a modeling tool that will allow novel, agile hull designs to be rapidly appraised for their effects on motion induced sickness will greatly reduce the costs involved in making and testing prototypes and estimating sea sickness from curves that may not apply to newer designs. The tool we propose uses empirical data to estimate the severity and duration of motion sickness on cognitive performance from novel hull designs in a variety of sea conditions and motions. Faster and more maneuverable ships are expected in many maritime environments from warships to ferry boats. The tool will allow the impact on crew effectiveness and comfort to be estimated early in the development of the ship. We anticipate monetary benefits to the designers and builders and a safer, easier voyage for passengers and crew.

Title:The Identification and Implementation of a Cognitive Metrics Suite for the Evaluation and Design of Tools to Enhance Warfighter Job Performance
Abstract:Naval systems of the future will be more multi-functional resulting in a higher cognitive demand on the operator. Furthermore, future systems will permit dramatic reductions in manpower that will require even more care in function allocation and will further increase cognitive demands on the operator. With highly technological systems implemented to enhance task performance it is essential to evaluate each component of the system for its cognitive requirements so it will accurately aid the operator in their performance. We will test the feasibility of identifying cognitive requirements using Cognitive Task Analysis (CTA). A basis for defining and developing cognitive measurements for technologies will be derived. From this a cognitive metrics suite will be developed to encompass all cognitive requirements for performance. This cognitive metrics suite will provide measurements in aspects of cognitive performance, and will provide an understanding of what tasks can and cannot be automated into systems. Also, with this cognitive metrics suite, new technologies can be designed and evaluated, resulting in innovative and usable technologies that increase warfighter performance, situation awareness, decision making, and timeliness. Through the development and identification of a cognitive metrics suite for the evaluation of technologies, a fundamental basis will be made for the future design of systems that will take human cognitive functions and capabilities into consideration. In this, systems will be more usable, innovative, and will address issues on how to organize and manage manning issues. In understanding decisions, judgments, challenges, and strategies that are needed for job performance, naval systems along with other analogous military systems can be designed and evaluated. Along with this, aircraft systems design and process control facilities would also benefit from having a cognitive metrics suite for the evaluation of systems.

Title:Methods & Metrics to Measure the Impact of Knowledge Superiority Technologies on the Warfighter
Abstract:Many new hardware and software technologies are currently under consideration for improving warfighter situation awareness, task performance, and decision making onboard Navy ships. If successful, these systems have the capability of not only improving the effectiveness of our armed forces, but also aiding in reducing manpower requirements on ships, a current, high priority Navy goal. To achieve this goal, however, requires that the Navy is able to quickly and accurately assess the costs and benefits associated with these new concepts so that worthwhile tools can be incorporated into future system designs and other concepts discarded prior to incurring the extensive development costs associated with such technologies. In this SBIR, we will develop an Automated Measurement Battery that contains a set of human performance evaluation methods and metrics that allow the impact of new technologies on human performance to be assessed in a reliable, valid and consistent manner. The linkage between such human performance measures and resultant shipboard manning requirements will also be provided by the tool. The Automated Measurement Battery developed under this program will have commercialization potential in many different venues where similar challenges exist for evaluating new technologies for human interfaces. First it can be used to guide decision making on future U. S. Navy programs, and on the programs of allied forces (e.g. UK Applied Research Programme). In addition, it is anticipated that the tool would have considerable applicability to similar design decisions for other DOD systems (Air Force, Army, Marines, Coast Guard) and large, complex non-military systems (e.g. NASA, DOE). Private sector applications also have considerable commercialization potential, including manufacturing and power plant operations, air traffic control systems, commercial maritime applications and command and control systems.

Title:Hardware Accelerated RF Modeling of Shipboard Environments
Abstract:In this effort we propose to develop an integrated analysis and design environment for the rigorous electromagnetic analysis and design of complex shipboard RF interactions for low frequencies (30MHz-2GHz). This integrated environment will include the ability to predict the scattering and EMI coupling of RF apertures and include a both a wide variety of antenna types as well as complex topside electromagnetic environments. To this end, we will expand and integrate (1) our novel application specific hardware system capable of performing rigorous electromagnetic simulations in a fraction of the time required by conventional approaches, including high performance computer systems; and (2) our 3D computer aided design (CAD) graphical interface. The ultimate development of this integrated environment is a topside design tool for ship design engineers that can be implemented using an ordinary PC. Commercial applications such as the communications industry will benefit directly from this software module in solving EMI/Coupling problems on a low cost platform.

Title:Simulation of Low Frequency (< 2 GHz) EMI and Coupling in Shipboard Environments
Abstract:In this Phase I Small Business Innovation Research project, we propose to develop a software tool for the modeling of low frequency EMI and coupling in complex shipboard environments. The performance of antenna systems is affected by their mounting platform. In addition, different antenna systems may couple to each other through the free space or their common platform. The coupling effects have to be taken into account in the antenna design process. Rather than costly antenna placement experiments and exorbitant coupling measurements, the proposed software provides a virtual environment for simulation of these effects. A hybrid frequency domain and time domain technique has been proposed for efficient full-wave simulation of large-scale shipboard environments. The Phase I feasibility study will demonstrate the concept of the hybrid technique for coupling of two antennas on a variety of common platforms. The proposed software tool will be used for the design of phased arrays and other shipboard antenna systems. These types of antennas have a variety of applications in both military and civilian communications and sensing systems.

Title:Simulation of Low Frequency (< 2 GHz) EMI and Coupling in Shipboard Environments
Abstract:This Phase I effort will develop accurate and numerically efficient Computational EM techniques for analyzing direct and indirect coupling problems in topside environment, and estimating co-site interference problems in this environment in the VHF to L-band range. We propose two new lines of attack in this effort. First, we will develop novel approaches that would substantially extend the range of applicability of the existing CEM tools, enabling them to be scaled to much larger problems than is currently possible. Second, we propose to develop new methods for hybridizing the MoM with the FDTD, that would take advantage of the salutary features, complement the ranges of applicability of the two (PEC vs. non-PEC structures), and dovetail them in a seamless manner. Our first step would be to develop codes that can predict the performance of antennas of various types operating in the 30 MHz to 2 GHz range and in a complex topside environment, which may either be PEC or non-PEC materials, e.g., absorbers, composites, and combinations thereof. Subsequently, we will extend these capabilities of these codes so that they can simulate the problem of coupling between two radiators that are designed to operate at two different frequencies, in general. Anticipated developments of the novel CEM tools would be of immediate use to several other projects of interest to various DoD agencies, especially the Navy, in connection with EMI analysis of proposed or existing designs, for which no accurate tools are currently available. Commercial organizations, such as government contractors, would also benefit from such tools that would certainly find a plethora of applications in EMI, EMC, RADHAZ, Non-lethal weapon and Security-type problems. RMA has been developing and marketing special-purpose CEM codes for more than 25 years, with a customer base comprising of DoD agencies and their contractors, and commercial code developers in the areas of antennas, MMIC, RFIC and Wireless circuits. RMA is currently offering several CEM codes to DoD contractors for RCS computation, EMI/EMC modeling and antenna design.

Title:High Frequency (> 2 GHz) Inter-Aperture Direct Coupling and Radiation
Abstract:Rigorous modeling of topside ship apertures and finite arrays involving many thousands of array elements is a formidable computational task. The problem is further exacerbated by the presence of several such apertures and their interactions in the presence other ship structures and scattering effects. The concurrent need to model broadband elements, frequency selective surfaces, absorber treatments around the array and the nearby tower surfaces, all add to major modeling challenges. Moreover, rigorous or sufficiently accurate techniques must be used to compute the low level coupling necessary for the design of these topside ship apertures. In this proposal, we bring together methods that have been demonstrated for large complex finite arrays and employ a set of innovative fast techniques to reduce memory and CPU so that evaluations of arrays with many thousands of elements. Another important aspect of this proposal is the introduction of a very unique approach which casts the aperture fields into a minimal set of rays. During Phase I, we will demonstrate the proposed integration of high frequency methods and carry out initial validation. In Phase II, we will fully develop and validate the methods and associated codes for realistic treated structures and develop a graphical interface. Computational tools developed will be applicable to both for antenna performance predictions and also for radar signature calculations. This tool can also be used in commercial aviation, transportation and the security industry. The commercial world will benefit directly from this software module in solving EMI/Coupling problems, e.g., companies in the communication business. Growing applications are also found in medical imaging area.

Title:High Frequency (> 2 GHz) Inter-Aperture Direct Coupling and Radiation
Abstract:This Phase I proposal for research and exploratory development would address the problem of High Frequency (>2 GHz) Inter-aperture Direct Coupling and Radiation in a shipboard environment. Our objective would be to predict the deleterious effects resulting from these couplings-and from extraneous scattering from obstacles such as masts and other structures-on the performance (gain, sidelobe, etc.) of the antennas. Modeling these problems is important for determining their placements in the topside environment, where the EMI and EMC issues are vitally important, as is estimating the biological hazard posed by high power microwave radiation from the radar antennas. We propose to develop a novel approach, based on the newly introduced Characteristic Basis Function Method (CBFM) employed in conjunction with either the CFDTD or an MoM code, that would enable us to handle arbitrarily large phased arrays, even comprising of thousands of elements. Next, we will show how the same approach can be used to address the problem of coupling between two large apertures, not only when the distance between the antennas (or between an antenna and a scatterer) is small, but also when this separation distance falls in the large or intermediate regimes, in a seamless manner. Anticipated developments of the novel CEM tools would be of immediate use to several other projects of interest to various DoD agencies, especially the Navy, in connection with EMI analysis of proposed or existing designs, for which no accurate tools are currently available. Commercial organizations, such as government contractors, would also benefit from such tools that would certainly find a plethora of applications in EMI, EMC, RADHAZ, Non-lethal weapon and Security-type problems.

Extensive plans are also being made to market more advanced versions of the CFDTD code to several DoD contractors engaged in the design of airborne and shipboard antennas, as well as to a number of organizations engaged in EMI and EMC problems

Title:High Frequency (> 2 GHz) Inter-Aperture Direct Coupling and Radiation
Abstract:Existing and future Naval vessels require multiple antenna apertures for applications such as communications, electronic warfare (EW), and electronic sensor measures (ESM) at S-Band and higher frequencies. Since space is limited on a vessel, the radio frequency (RF) apertures are required to operate in close physical proximity to each other and often in-band with other systems. This can result in interference between transmitting and receiving apertures. The objective of this proposal is to develop an integrated, intuitive modeling and simulation tool to accurately analyze RF aperture performance in complex environments in a cost effective manner. This tool will characterize coupling between multiple RF apertures, installed transmit and receive performance of apertures, and radiation hazard (RADHAZ) zones due to RF apertures. The tool will also accurately characterize the effect of structures such as masts, railings, and other antenna structures including radomes composed of frequency selective surface (FSS) materials. The accuracy of the new toolsuite will be thoroughly validated using multiple empirical and deterministic modeling and simulation tools. The resulting RF aperture integrated tool suite will revolutionize the Navy's ability to install new systems on existing vessels and next-generation vessels. The resulting physics-based antenna modeling tool will revolutionize the developer's and the warfighter's ability to maintain effective communication links. This tool will enable the user to perform analysis of extremely diverse environments with multiple systems over wide frequency ranges. Additionally, the analyst and the system designer will be able to use this tool to assess and guide the development of new RF systems with orders of magnitude in improved accuracy and reduction of cost, production, and testing for multiple high frequency systems.

Title:Novel Composite Penetrator/Carrier Round for 5"/62 Naval Gun
Abstract:KaZaK Composites Incorporated (KCI) and its team of ordnance designers proposes to develop a new capability for the EX 172 5" (127 mm) cargo round, analogous to the 105 mm APERS (flechette) rounds deployed by the US Army. The key components of this development include a hybrid metal/composite carrier configurations designed to expel a uniform and lethally dense pattern of KE sub-projectiles, after surviving the launch loads of the Mark 45 Mod 4 gun system. The composite ogive shell can be designed to quickly fragment under internal pressurization, after providing exceptional strength in the setback loads. The KE sub-projectiles may for some targets be the existing 8 grain (MIL-F-48167) and/or 13 grain (MIL-F-48168) steel flechettes, or may be tailored penetrators having size and material dictated by specific target features. Graphite composite and hybrid metal/composite penetrator designs will be developed to optimize lethality against targets of interest within cost and weight boundaries established by the sponsor. One advantage of the composite penetrators is that they may provide sufficiently lethal projectiles at much lower weight than steel or refractory metal penetrators. The KCI team will also develop asymmetric fuzing/expulsion methods to optimize penetrator cloud shape and orientation with respect to the target. The basic composite projectile design concept developed here has near term applicability to APERS rounds for the 120 mm breech loading mortar fire support component of the IAV and FCS vehicle families. Additionally, the KE payload round concept may have superior thin skin target effectiveness for 81 mm and 120 mm drop-fired mortar rounds in the close support role. These applications possess increased urgency with the developing war on terrorism, since they would provide highly effective self-defense mechanisms for light objective force assets in asymmetric tactical situations such as have been experienced (e.g. Mogadishu) and may well be the norm for future force deployments.

Title: Low-Cost Autonomous Kinetic Energy (KE) Penetrator Payload for EX 172 Cargo Round
Abstract:Precision-guided autonomous munitions concepts are immediately adaptable for use in a low-cost kinetic energy penetrator deployed from the EX 172 Cargo Round projectile. Feasibility of implementing an autonomous KE penetrator concept can be demonstrated near-term using gun-hardened micro components developed for exo-atmospheric miniature interceptors. Tanner Research is proposing to integrate MEMS-based spectral seeker and thruster components (using deflagrating energetics) as key enabling technologies to implement an autonomous KE penetrator. The smart KE penetrator is presumably fired from the upgraded 5"/62 Mk 45 Mod 4 gun system in the EX 172 Cargo Round. Our objective is to conclusively demonstrate increased combat effectiveness and lethality of an autonomous KE penetrator by substantially reducing target miss distance. This will be accomplished by dynamically controlling the overall pattern of KE penetrator dispersion. This pattern can be modified for specific tactical target sets by integrating precision guidance, micro thruster-based divert and attitude control system (DACS), and fin stabilization. The seeker will spectrally detect an optical signature of interest in the field of view (FOV), regardless of clutter, and guide the KE penetrator to the center-of-mass. Guidance commands are implemented using the micro thruster DACS to divert into the center-of-mass. Leverage ongoing development of autonomous projectile technologies. Significant cost savings from using low cost mass fabrication techniques developed on other autonomous projectile programs. Use of low-cost GN&C concepts, employing focal plane signal processing to center the target, control smart KE penetrator maneuvering with DACS, assuring enhanced hit-to-kill lethality. The production cost of a smart KE penetrator, leveraging other programs, will be about $100 per rod.

Title:Kinetic Energy Cargo Round
Abstract:Veritay proposes to develop a preliminary design of a kinetic energy (KE) payload and expulsion system for the EX172 Cargo round. The payload will consist of numerous KE penetrators. One of the most important aspects of the design is devising a system for effectively dispensing the payload from inside the round. To be effective, the individual penetrators of the payload must be dispersed in a uniform pattern over a large footprint. Additionally, they must be dispersed at a high-velocity in a controlled manner to ensure maximum penetration. If after dispersal the velocity drops too much or the penetrators begin to tumble, their penetrating capability will be diminished. The specific objectives for the Phase I effort are to: 1) Ascertain appropriate design criteria for the payload and expulsion system, 2) Develop a preliminary design of the payload and expulsion system, and 3) Conduct a limited number of experiments demonstrating the expulsion system. If provided by the Navy, we will use government furnished Cargo hardware (bodies and base plugs) to conduct expulsion tests. The concepts formulated and developed during the proposed program may be incorporated into ammunition designed to provide a high level of lethality while limiting unintended hazards.

Title:Linearly-Graded Ceramic Coating Fabrication Process for Gun Barrels
Abstract:Alameda Applied Sciences Corporation will use its proprietary Coaxial Energetic Deposition process to deposit a linearly-graded ceramic coating on the inside of gun barrels. This coating will transition smoothly from a fully ceramic interior surface, which is exposed to the harsh firing environment, to a fully metallic base, which is directly interfaced with the metal barrel. Analytical tests will be performed to determine the properties of the coatings. It is anticipated that this coating will extend the life of gun barrels, in particular, the barrels of future advanced guns, which are expected to use high-temperature propellants and fire at high rates. In addition to this application area, tests have shown that ceramic coatings deposited using our Coaxial Energetic Deposition process extend the life of olefin production tubes. Alameda Applied Sciences is in negotiations to license this technology for olefin manufacturing.

Title:Hybrid Composite Gun Liner With Ceramic Bore
Abstract:Ceracom, Inc. and our team members will demonstrate methods of designing and fabricating highly integrated, high strength hybrid composite gun barrel liners. These will withstand the extreme environments encountered in advanced, large caliber Navy gun systems, such as the 5" 62 Caliber MK-45 Mod 4. Our hybrid composite structures incorporate a toughened ceramic bore surface that gradually transitions into a supporting metal structure, eliminating discrete interfaces, and making it a fully integrated structural member that bypasses many of the shortfalls previously observed with coatings or monolithic ceramic inserts. Ceracom's hybrid liners will withstand the extreme temperatures, pressures, and chemicals encountered with advanced munitions, e.g., ERGM or Barrage Round. The hybrid gun liners will not only enable increased performance, but their affordable acquisition costs and longer service lives will result in reduced life cycle costs. We will demonstrate the feasibility of fabricating ceramic bore gun liners for major caliber Navy gun systems. We will generate potential liner designs based on significant material testing, analysis and computational models. During the Phase II and III programs we will further develop and apply our materials, structures, design tools, engineering designs, and manufacturing processes to produce components for applicable Navy gun systems. These materials will enable development of major caliber, high performance Navy gun systems such as the 5" 62 Caliber MK45 Mod 4 or the 155mm AGS gun. Ceracom is now working with an industrtial partner to develop these hybrid composites as commercial product, heater substrates

Title:Magnetic Fabrication of a Whisker-Toughened Ceramic Thermal Gradient Gun Barrel
Abstract:This project develops an innovative and efficient ceramic/metal thermal gradient gun barrel which provides a linear gradient in material and density from a fully ceramic interior to a fully metallic exterior. We will develop a barrel insert and magnetic slip casting process to fabricate a material that gradually changes from pure ceramic at the bore, through a mixed ceramic-metal matrix, to a pure metal. This ensures a strong bond between the ceramic and metal while spreading the thermal/ mechanical stresses through the gradient area. The metal outer layer interfaces with a conventional metal or composite barrel. Slip casting of a fine steel whisker-toughened ceramic subjected to centrifugal rotation and magnetic fields produces a linear distribution of the ceramic matrix from a pure ceramic to a sintered metal. The ceramic/metal gradient material can be used for five inch, eight inch or155 millimeter liners. This new barrel reduces life cycle costs by extending barrel life, eliminating spares and decreasing inventories. Theoretical development, solid/fluid modeling and experiments will demonstrate the feasibility of our concept. This new material design technology can be manufactured at costs comparable to materials currently being used and can be retrofitted to existing weapons.

Title:The Development of Gun Barrel Processing That Linearly Gradates From A Ceramic Liner To A Metal Exterior
Abstract:State-of-the-art gun barrels exhibit excessive chemical and mechanical wear when subjected to the advanced requirements of rapid fire with high flame temperature propellants. Ceramic and ceramic based interior liners offer significant potential to meet advanced requirements, but past processing of fitting inside a steel barrel creating an abrupt interface has resulted in an inability of withstanding the mechanical and thermal cyclic loads under virtually all firing scenarios. A smooth and linear gradation from the ceramic face interior to a fully metallic exterior offers an excellent probability such liners can meet advanced requirements for large guns with a greater than five inch bore. This program will investigate monolithic ceramics and ceramic matrix composite, and refractory metal cermets as interior liners utilizing fabrication processing that results in a linear and smooth gradation from the liner composition to a fully metallic exterior of steel. In addition, a high thermal conductivity copper matrix composite with mechanical properties at least equivalent to steel will also be investigated as the barrel structure. The various materials combinations will be fabricated, characterized and down selected for barrel section deliveries in this program and for optimization in Phase II. In addition to gun barrel applications for all gun types from 5.56 mm to 8 inch throughout DoD, materials that grade from a ceramic base to a structural metal have applications in both IC and gas turbine engines, clutches and brakes, energy conversion systems, insulations, and general wear and erosion components.

Title:The Development of an Optimized Unitary Warhead for the ERGM System
Abstract:A unitary warhead concept for the EX 171 Extended Range Guided Munition (ERGM) gun-fired projectile is proposed that incorporates pre-formed fragments in combination with an integrated composite/metallic casing. The use of pre-formed fragments ensures optimal fragment output, while the composite/metallic casing provides the structural support required to survive gun launch. The casing is a combination of a thin inner metallic shell surrounded by pre-formed fragments that are contained within an outer composite structure. In order to minimize weight, the composite structure will be designed to carry a majority of the structural load, with some structural load-bearing capacity also provided by the inner metallic shell. A composite casing will be designed to withstand the large accelerations and bending moments experienced during gun launch. Decoupling the fragments from the structural load-bearing capacity of the casing enables the incorporation of the most lethal fragments for the given target set. The Phase I program will enable an assessment as to the practicality of using the proposed unitary warhead concept for the ERGM system, and for other munition systems currently fielded or in development. The systems could be other gun-fired projectiles and missile systems for all of the DoD services. The primary beneficiary of the Phase II program research is the Department of Defense, especially those agencies utilizing weapon systems with fragmenting warheads. Potential commercial applications include areas where high strength and high temperature composite structures are required. This could include composite over-wrapped pressure vessels (COPVs) for automotive natural-gas vehicle (NGV) tanks, composite risers for offshore oil drilling, integrally wound composite tubes/end fittings for the conversion industry, composite utility poles or lightweight sporting goods.

Title:Pre-fragmented Warhead Plate for EX 171 ERGM
Abstract:In cooperation with Advanced Ordinance Technologies, (AOT), Liquidmetal Technologies will conduct research and development to apply the material properties of amorphous alloys to the design of a pre-fragmented or fragmented plate for a five-inch diameter, forward-firing warhead. Plate design research will focus on capitalizing amorphous alloy's unique strength-to-weight ratio, form-manufacturing ability and fracture (glass-like atomic composition) to meet the Navy's requirements for Naval Surface fire against personnel, vehicles, unarmored equipment and asymmetric ship defense targets such as fast boats. Alternative casting and combining of supplemental fragmentary components will constitute the main line of research, with consideration given to a system cost goal of $500-$1,000 per plate. Successful adaptation of amorphous metal alloys to a pre-fragmented or fragmented plate for Naval Surface munitions will present munitions designers with a much larger trade-space of lethality, range, weight and cost. Alternative uses of amorphous alloys in commercial development might include a number of shock, absorption or controlled energy absorption mechanisms.

Title:Pre-fragmented Warhead Plate for EX 171 ERGM
Abstract:Navy Combat Ships and commercial vessels have experienced major damage and loss of life due to attacks from terrorists using small boats laden with explosives. The attack on the USS Cole caused a loss of over 17 lives and damage to the ship that totaled more than $200 million. Effective weapons against these threats that can be fired from NSFS, MK 45, 5-inch systems are needed. Current gun projectiles are inefficient as warheads because they break into random fragments that are large and irregular in size upon detonation. In this project, a high strength composite warhead plate will be developed to provide the required strength necessary to survive gun launch, yet be pre-fragmented so that the fragment size, shape and pattern can be optimized for maximum lethal effect when used against land based and fast moving sea targets. Results carried out prior to Phase I will be used to determine material conceptual designs for a pre-fragmented plate that is strong enough to survive gun launch. Projectile warhead plate component prototypes will be built along with test articles for laboratory evaluation. A plan for Phase II will be prepared that will include the testing of prototype projectiles. Benefits of the proposed approach will include lower warhead costs, reduction of explosive hazards during submunitions loading and off-loading, and the improvement of projectile handling throughout life cycle. These new warheads will allow surface combatants to play an expanded role in NSFS - guarding harbors - and will provide increased ship self protection in-transit and during re-fueling stops in areas where terrorists cells may be operating. A low cost, high fragmentation warhead is also needed to attack soft targets, i.e. enemy personnel, trucks, and unarmored vehicles/equipment.

Title:Geo-Political Analysis and Modeling Environment (GAME): A Decision Support Tool for U.S. Naval Future Force Architecture Analysis
Abstract:Determining the composition of future naval force architectures has never depended so critically upon understanding the emerging geo-political environment as it does today. At the same time, however, the end of the Cold War and emergence of non-state asymmetric threat entities have removed the key anchor assumptions that guided long-term naval strategic planning for over five decades. Furthermore, an explosion of data as part of the global revolution in information technology has accompanied the rise in uncertainty associated with the on-going geo-strategic paradigm shift. The combination of ambiguous future trends and ubiquitous praecognita electronica have left naval force architecture analysts drowning in data but starving for information that provides fiscally and culturally constrained alternative geo-political contexts. Cyberneutics, Inc. and its subcontractor Veridian Systems Division, Inc. propose to address this situation with the Geo-Political Analysis and Modeling Environment (GAME), a standard methodology and decision support tool to assist long-term context development for force design and planning efforts. GAME will provide an end-to-end environment where analysts making geo-political predictions can build "future worlds" using the best tool for the task of indicator construction from a library of pre-built components, including tools to support tapping external data sources. Once built, GAME will support continuous monitoring of the future world and iterative updating of the underlying assumptions and models. The result of this effort will be Cyberneutics' Geo-Political Analysis and Modeling Environment (GAME) that includes the Future Worlds Builder, the Template Maker, an Indicator Construction Toolkit, the Future Worlds Monitor, and the Worlds Data Manager. In addition to the DoD market where analysts will be able to use this tool directly to make geo-political predictions for force architecture planning, Cyberneutics has identified the global corporate strategic planning sector as a strong market for these capabilities including: investment planning, global security analysis, wholesale distribution, and telecommunications. In addition to the global corporate market, Cyberneutics has identified organizations that are providing international support for a variety of functions that could benefit from being able to generate and evaluate future worlds. These include security (e.g., NATO), health (e.g., the World Health Organization), and environmental planning and humanitarian/disaster relief (e.g., the American Red Cross).

Title:Geo-political Ratings and Indicators for Planning System (GRIPS)
Abstract:Successful long term strategic planning requires a thorough and systematic evaluation of the context, or future conditions, for the plans being developed. We propose to validate and build on the Navy's previous geo-political modeling and estimating efforts to develop the Geo-political Ratings and Indicators for Planning System (GRIPS) to provide military planners with a consistent methodology to evaluate the long-term geo-political contexts for planning future force architecture. A central foundation of the GRIPS methodology will be an estimator aggregation approach that gives planners the ability to quickly and easily visualize the enormous volumes of data pertinent to military planning. GRIPS will ultimately provide automated extraction from data sources and systematic organization and aggregation for rapid communication and understanding of the probable future contexts. GRIPS will also apply data mining and forecasting techniques to the data gathered in order to better anticipate future trends at the aggregate level. The GRIPS World Geo-political Dashboard will provide planners with the ability to quickly visualize future geo-political contexts and drill into the appropriate level of detail in the planning process. The initial focus is on military planning, and we envision that the above benefits will make GRIPS an invaluable tool for the process of military planning. However, we also envision GRIPS as being useful for Homeland Defense analysts in forecasting terrorist activities by predicting "hot spots" for terrorist cells through applying the concepts of aggregated indicators and ratings to the arena of terrorist activity. Furthermore, we anticipate the benefits of GRIPS will produce numerous commercial opportunities. One area of application would be international investment analysis, in which we would envision investment analysts using GRIPS to identify and predict the risks of foreign investments, with the ability to detail the interaction of economic, political, and social implications of the investments. Another area of commercial application would be in planning overseas expansion of multi-national organizations. GRIPS could provide information regarding the political and social stability, risk of expropriation, and composition of the future labor force. In corporate security, GRIPS could be used to identify risk similar to the application for military or anti-terrorism planning. GRIPS would also be valuable for marketing organizations by modifying the aggregation of indicators to focus on rating international markets for a product type, as configured by the user.

Title: Term Geo-Political Context Decision Support Tool
Abstract:We propose to investigate the feasibility of converting our analytic platform to build, test, and distribute computational models. The platform can access existing databases over standard protocols and has these characteristics: . Warehouse data in a proper database instead of spreadsheets. . Run complex models much faster than spreadsheets or other typical languages. . Optimize model parameters over historical data using Genetic Algorithms. . Walk-forward the model's "out-of-sample" in time, to simulate real-time performance. . Retain confidential aspects of the models as the user's private data even if the executable model is distributed. A preliminary version of this tool has been developed for migrating analytic applications in Finance, from Spreadsheets to a more appropriate platform. In its year of operation, the migration has opened unprecedented possibilities for creating, testing vastly more complex models. Mathematicus Labs has extensive experience in the implementation of the intended solution and not merely to provide software tools. We therefore propose to investigate TWO related areas. . We propose to validate and optimize the existing models. Moreover, to investigate additional inputs to these models which may improve their performance. . We aim to investigate a systematic scenario-exploration methodology which will address the current "speculative" approach. As alluded in sections 1.3 and 1.4 of the proposal, a similar version of the proposed product is in existence and has been licensed to clients in finance from which we can show revenue. However, the proposed extensions and revisions makes this product suitable to a much wider audience in the business community as well as virtually any other policy setting organization particularly in the US-government.

Title:Optimal Manning Analysis Tool for Grouped Forces
Abstract:The future Navy's tactical command and control organization and processes will evolve with the Network Centric Warfare concepts. In order to assess the effectiveness of new grouped force organizational structures, we propose to develop a new tool based on the solid principles of modeling and simulation. The proposed tool will be used to generate preliminary quantitative performance predictions for the expected effects of grouped force mission, task, and capability requirements on manpower requirements and cost. The tool will consist of four software modules: 1. A data collection/translation tool will assist users in importing data from other sources and collecting new crew and task data 2. A functional description tool will assist users in performing and documenting a function and task analysis. 3. The simulation development tool will let users build simulation models of combat and non-combat missions. 4. The data analysis tool will have three pieces: - A report generator presents reports and graphs of simulation results. - A task allocator uses clustering techniques to suggest task allocation alternatives to mitigate excessive workload/manhours and risk. - A life cycle cost estimator provides insights to the potential affordability of a system design. The proposed software tool will advance the state of the art in manning evaluation technology. The grouped forces analysis tool described in this proposal is based on a time-proven technique of system analysis (i.e., task network modeling), and also provides a previously unavailable and highly innovative data collection and translation capability. These analytical techniques can be applied to any group of systems and humans that are undergoing an organizational reengineering process.

Title:Optimal Manning Analysis Tool for Grouped Forces
Abstract:From the late 1960s to now, Fleet forces' manpower requirements have been established for ship classes and individual ships (e.g., DDG-51, CG-47, LPD-17, etc.) by Ship Manpower Documents (SMD), aviation activity requirements by Squadron Manpower Documents (SQMD) and Fleet Manpower Documents (FMD) for deploying staffs and other units (e.g., Naval Beach Group elements, Tactical Air Control Squadrons, etc.). These requirements are almost exclusively produced from own-unit workload that takes place within the unit's physical boundaries. There is an urgent need to develop a workload/manpower model that will examine, assess and provide alternatives for workforce optimization or redistribution in Grouped Forces. We propose to incorporate an enhanced modeling architecture into our proven Manpower Analysis and Prediction System (MAPS). MMCI will expand MAPS capabilities to allow the combination of discrete ship elements into a battle force starting at the Simple ARG level ensuring scalability to expand this capability beyond this small demonstration to eventually have the capabilities of modeling a CVBG and beyond. The study will combine the ROC/POE statements for the individual units into a combined database of scenario-based capabilities. These enhancements will enable MAPS to better identify common/duplicated skill capabilities among the Group Force for assessment and optimization. The anticipated benefits of this SBIR research by incorporating enhanced modeling architecture into the current MAPS processes will 1. increase the accuracy, rigor and speed of assessing workload and manpower requirements distribution among the units of Grouped Forces, 2. potentially map manpower to capabilities for a Grouped Force to provide the foundation for mission readiness assessment, and 3. to provide new concept workload/manpower models that could eventually be linked to other Human Systems Integrations (HSI) tools such as the NAVSEA Advanced Ship Systems Engineering Tool (ASSET) or the Navy Total Force Manpower Management System (TFMMS). The potential commercial application of this SBIR research and development in building an integrated workload/manpower/readiness assessment models can be used for: 1. Large, diverse corporate organizations. 2. Large, diverse government organizations. 3. Such things as routine and emergency response capabilities and manpower. (E.g., all of the hospitals, clinics and emergency services in a civic area or region.)

Title:Beam Control (BC) for Ship Self-Defense
Abstract:Under this Phase I SBIR, the Kestrel Corporation proposes to demonstrate the advantages of a novel optical technique for measuring wavefront aberrations under maritime propagation conditions. The proposed technique has been conceptually demonstrated during earlier laboratory experiments where our distorted grating based wavefront sensor reconstructed phase maps under highly scintillated, but non-scattering, conditions that could not accurately be reconstructed using conventional wavefront sensors. The technique also has the potential of overcoming existing shortfalls in wavefront sensing by providing increased accuracy, improved optical efficiency, and relaxed alignment requirements. The basis for our commercialization is an adaptation of the distorted grating wavefront sensor to a medical problem in ophthalmic imaging. The focus of these interests is adapting the novel wavefront sensing research to cornea wavefront measurements and in using the sensor as a replacement for existing wavefront measurement techniques in an adaptive optics enhancement to fundus imaging. The most direct military application of the proposed work is with the Navy's HEL as a wavefront sensor that is better suited to the highly scintillated propagation conditions expected by this weapon system. In this Navy application an ability to provide atmospheric corrections is critical to overall system performance. Intrinsic to being able to make these corrections is knowledge of the current propagation path characteristics. Use in Space Based HEL system, where the laser source is located on the Earth's surface, is a logical extension of the research as are potentials in HEL laser diagnostics. Uses in adaptive optics imaging systems for tactical battlefield employment as a wavefront sensor for adaptive optics use by multiple DoD agencies is projected.

Title:Comprehensive Simulation of Beam Control System for Ship Self-Defense
Abstract:Building upon a well established wave-optics propagation code, we propose to develop a generalized and sophisticated beam-control simulation tool that will predict the performance of a High-Energy Laser (HEL) beam-control system for ship self-defense. During Phase I, we propose to add to the existing code a number of features specific to the ship self-defense problem. These features include: (1) Modeling of near-sea-level atmospheric turbulence. (2) Incorporation of certain optical attenuation and scattering information. (3) Tailoring and exploration of an existing thermal blooming capability. (4) Incorporation of simple target models for targets of interest to shipboard HELs. We propose the use of WaveTrain, a wave-optics simulation tool developed by MZA principally in support of the Air Force's Airborne Laser Program. The basic code is already well developed, but requires additional features specific to the marine environment. We also propose a Phase I Option. During the option period, the objective will be to begin the construction and initial exercise of a prototype system model for overall performance prediction for a shipboard HEL system. This would provide a transition to a Phase II effort, during which we envision a broad elaboration of the prototype system model, incorporation and/or improvements of individual component models, and the exercise of the enhanced system model over a significant range of ship self-defense engagement scenarios. BENEFITS TO THE NAVY: When we complete our proposed work, the ship-board-HEL research community will have its disposal powerful simulation and analysis capabilities which will assist in the design, implementation, and diagnosis of candidate designs and fielded systems. Users will be able to initially evaluate beam control concepts using inexpensive simulations rather than field experiments. Naturally, final real-world confirmation will always be required, but our project will directly assist in reducing the cost, development time, and risk of fielding proposed HEL weapons systems. These reductions in required research and development resources will allow the war fighter to receive more effective weapons in a more timely manner. POTENTIAL COMMERCIAL APPLICATIONS: Potential commercial applications of the adaptive-optics type of beam-control technology exist in at least three sectors. First, some wavefront-sensing and beam-control techniques are beginning to be used in ophthalmology, particularly in conjunction with laser eye surgery. Second, propagation through atmospheric turbulence is involved in the design and construction of "free-space" optical communication networks. Third, imaging for astronomical and remote earth-sensing applications can make use of (and at least for astronomy, is already making use of) beam-control techniques. The first two sectors are evidently the more significant in terms of monetary potential. The business plan that MZA would use to enter these markets is the licensing of our simulation software to firms that have established niches in specific biomedical or telecommunications areas.

Title:Broadband Processing for Mine Warfare Sonar
Abstract:This Phase I proposal presents a unique opportunity to improve active sonar capability for mine detection and classification through the use of robust signal processing of broadband signals. This effort will improve target recognition in environments with strong reverberation and dense multi-path. The current importance of operating in littoral waters, along with an increased noise background and reverberation conditions, and the high importance of mine avoidance, establishes a high priority for improved broadband active sonar performance. Stronger and more complex multipath propagation increases clutter, reduces the probability of detection, impacts target localization, and degrades target classification performance. Often target returns are received using existing signal processing methods, but the target returns are embedded in clutter making target classification difficult. The only way to make a true advance in system performance is not to select a different operating point on a fixed receiver operator characteristics (ROC) curve, but rather to shift the ROC curve itself. The work proposed here has the potential to improve the target minimum detectable level, to achieve processing gains against clutter, and to provide better estimation of contact features by shifting the ROC curve. Completion of this Phase I effort will result in development of technology that provides an improved broadband mine detection and classification capability for the AN/SQQ-32 minehunting sonar system. With appropriate interface modifications, this same capability could be provided to other U.S. Navy sonar systems and commercial systems that use acoustic energy to explore or characterize the ocean.

Title:Strong Torpedo Fiber Optic Communications Link
Abstract:Current wire guided torpedoes rely upon conventional metal conductors for the communications link between the submarine and torpedo. As the range of torpedoes increases, the bandwidth of this link decreases, and the rate of data transmission drops. The use of optical fiber cables in place of the conventional wire promises very significant increases in bandwidth and also a saving in space, since a single fiber can be used in place of the current 2 wires. The need therefore is for a small diameter (0.030") lightweight, low cost optical fiber cable that is sufficiently durable and robust to withstand the stresses associated with torpedo launch and deployment. We propose the use of a novel polymeric coating to produce a tight jacketed fiber optic cable, capable of sustaining loads of up to 30 lbs and with excellent moisture barrier properties. The cable will be manufactured using conventional extrusion techniques and at a cost of less than 20 c per m. Low cost, high tensile strength optical fiber cables have applications not only in wire guided torpedoes and other precision guided munitions, ( including TOW missiles for example ) but also in optical sensor technology and communications systems. The relatively simple construction of the proposed fiber cable, together with its high pull strength and inherent flame retardation characteristics, make it ideal for in building installation. The high temperature performance capabilities of the proposed cable design make it ideal for use in distributed temperature sensors.

Title:Strong, Economical Torpedo Fiber Optic Communications Link
Abstract:An SBIR Phase I program is proposed to research and develop a strong economical fiber optic micro-cable (SEFOMC) for application to a ship-side underwater payout of torpedo communication links. Currently available fiber optic components, micro-cables, ruggedized overcoatings, manufacturing technologies and alternate fiber optic micro-cable (FOMC) designs will be researched. This will be done in order to develop candidate designs for a strong, economical FOMC (SEFOMC) ship-side torpedo mounded dispenser (TMD) with low cost and high reliability. Research will include the fabrication of sample lengths of candidate SEFOMC designs that will be used in laboratory tests of both mechanical and optical characteristics. Preliminary TMD designs and payout coil winding assessments will be addressed in a Phase I option to enable results to be fed back into the candidate SEFOMC design process. A strong economical fiber optic micro-cable has immediate application and benefits to several ongoing or planned DOD programs and civilian industries. Use of torpedo mounted dispensers for underwater payout communication links alone is estimated to be as high as forty million feet yearly. Such a fiber optic communication cable would have immediate application in other areas such as underwater guided vehicles (UGVs), ocean probes or permanent communication links through deep water or other harsh environments including land-based and underground locations. High strength fiber optic payout communication links are currently needed for airborne applications and tethered aerostat based sensors. High reliability fiber optic communication links will be candidates for use in space and high performance aircraft applications. Ruggedized micro-cables have been investigated for application to deep well sensor probes that can be used during drilling operations.

Title:Submarine Emulsified and Mixed Hydraulic Oil Cleaning, Filtration and Reuse Aboard Ship
Abstract:Nelson Engineering proposes to research and develop a commercially-viable lightweight, portable filtration system capable of restoring hydraulic fluid to better than new conditions. Currently, hydraulic fluid is filtered at the 10-micron level. Our system will demonstrate the feasibility and cost-effectiveness of filtering to the sub-micron level with a filtration goal of 0.5 microns with a maximum water retention level of 0.05% saturation. We intend to maximize the use of commercial off the shelf (COTS) components to minimize development costs while maximizing repair parts availability. The incorporation of future technology advances is enhanced by the use of common industry components. Our system will use a number of technologies installed in tandem. This design will allow us to take full advantage of the unique capabilities and strengths of each component. The placement of hydraulic systems throughout the boat requires that the system be lightweight and portable and that the system be powered using standard electrical receptacles. We envision the entire purification system to be the size of a hand dolly. Simplicity, COTS usage, portability, and 120V electrical power all play pivotal roles in allowing for commercial marketing of the system. The market for a portable hydraulic fluid and lube oil purification device is sound. While the project utilizes COTS components that are readily available to many end-users, there is no currently marketed inexpensive, light-weight, portable, modular purification unit. A sizeable market portion is now excluded in small end-users who see no economic advantage in purchasing an expensive purification unit over paying for high recycling costs. Potential commercial clients are shipyards and repair facilities, bulk carriers, marinas, cruise ships, ferries, oil rigs, and other situations involving heavy hydraulic machinery in a marine environment. Military applications include marine avionics, naval surface vessels, coastal air forces, and military construction battalions.

Title:Development of a Supportability Performance Assessment System for Training Systems
Abstract:In order to win the war for recruitment and retention, the CNO has stated that sailors of today and tomorrow must be well trained and equipped. Given the diverse needs of training communities, acquisition managers, and curriculum developers it is ultimately important to provide accountability and ownership in any mechanism or process that intends to enhance performance. This SBIR project will develop an approach for an architecture that is extensible and scalable, and aligns the AN/SQQ-89(V) USW combat system as well as combat systems in the future with Task Force EXCEL objectives. Implementation of a Supportability Performance Assessment System within a tactical system architecture will provide a quantum increase in collaborative training and training evaluation capabilities that have here to for been unobtainable. We propose to illicit stakeholder involvement in development of the SPAS through solicitation of parametric data relationship mappings that will provide quantifiable metric data deemed critical in evaluation of skills application and acquirement of knowledge. Additionally, because some competencies are not directly observable/measurable (behaviors and attitudes for example), the proposed SPAS design and architecture would be sufficiently robust to enable monitoring of user and team action derivatives thereby providing repeatable standards to assess otherwise subjective MOEs. The proposed Supportability Assessment Performance System (SPAS) addresses the challenges presented by decreased time allocated to traditional classroom training and greater emphasis on just-in-time and other computer-delivered training. SPAS provides data gathered in significant enough detail to realistically appraise task performance. The SPAS technology can be a significant enhancement to the existing AAC Learning Management System (LMS), Data Driven Learning System (DDLS), and Knowledge Management System (KMS) suite. SPAS tasks can be loaded, edited, and published as Shareable Content Objects (SCOs), thus fulfilling a requirement of SCORM. This means SPAS is not restricted to AAC-produced LMS, and will therefore have wider appeal where an alternative LMS is already in place. AAC proposes to market the SPAS technology as a component of its current learning tools as well as an enhancement to existing SCORM-compliant learning management systems. AAC expects a broad demand for this unique solution. There is currently no similar system on the market. AAC's proposed SPAS will appeal to knowledge industries such as credit, banking, financial services, utilities, and insurance.

Title:An Intelligent Training Systems Performance Assessor
Abstract:We propose to develop an innovative performance evaluator to enable training developers and instructors to better monitor and assess training lesson and overall curriculum effectiveness. This will be accomplished by adapting our general Intelligent Tutoring system development platform, that already implements intelligent assessment and cognitive learning strategies based on sound pedagogical principles, to create an Intelligent Assessment System. Interfacing the Intelligent Assessment System with current trainers and curriculum, will enable training developers and instructors to better monitor and assess training lesson and overall curriculum effectiveness. The Intelligent Assessment System will be a tool to collect, monitor and analyze human interaction information from a training or tactical system involving individual or coordinated teams. In Phase I, we will determine the requirements and develop a system design for the intelligent assessment system. We will absolutely demonstrate the feasibility of our ideas through the development of a Phase I, proof-of-concept prototype. There are enormous opportunities for both commercial and governmental applications wherever training effectiveness, mentoring or team interaction are involved.

Title:Development of an Advanced Thermoelectric Cooling System for Unmanned Underwater Vehicles (UUVs)
Abstract: New thermoelectric materials with improved figure of merit, Z, are emerging from research laboratories and are soon to be available for applications. The need to conserve energy on UUVs points to the use of the new thermoelectric technology to more efficiently cool critical electrical components. This is an excellent initial cooling application for Hi-Z's multi-layer quantum well (MLQW) thermoelectrics. Hi-Z has already demonstrated representative small-scale couples of MLQW as thermoelectric generators and one of the MLQW materials as a Peltier cooling device. The proposed work will develop designs for practical cooling modules from these MLQW materials that can now be engineered. The development effort will include the electrical, thermal and mechanical means to combine the MLQW films into larger-scale devices. Particular needs of the U S Navy UUVs will be reviewed and application-specific cooling modules will be proposed for the cooling of critical electrical components. Performance predictions can be made based on the material data taken from Hi-Z's experimental work on the DARPA/ONR programs. From this is appears that the efficiency of the cooling function, as measured by COP, can be increased to as much as 4.0 to 6.0. Radm. Michael Sharp, program executive officer for mine and undersea warfare, has been quoted wanting to see "UUVs operate in days rather than hours". Thermoelectric cooling device improvements can be the enabling technology to achieve this goal and to bring UUVs into broad use and utility for the U S Navy. Thermoelecric cooling technology is used in various, limited commercial cooling and refrigeration applications. Improved efficiency, as measured by COP, to values like 4.0 to 6.0 will open many new applications where mechanically-powered vapor compression refrigeration is used today. Thus, MLQW technology holds promise for improved efficiency in electronics cooling and broad areas of refrigeration, such as air conditioning.

Title:Binary Oscillating Thermoelectric Chiller
Abstract:Thermoelectric (TE) Peltier/Seebeck coolers appear to be very attractive for use on unmanned underwater vehicles because of their absence of moving parts. The major problem with the approach is the limited coefficient of performance (COP). As a result, the maximum density of removed heat is less than 100 W/cm2. To address this problem, Physical Optics Corporation (POC) proposes to develop a new structure of cooling system, a novel Binary Oscillating Thermoelectric Chiller (BOTEC) for heat power acquisition and transport. The BOTEC is based on two major innovations: one in the heat-pipe area and the second in the narrow TE area. POC's thermoelectric device will significantly reduce the parasitic energy losses in a semiconductor structure, thus increasing by at least 3.5 times the COP from 0.6 to 2.1 which in turn, makes possible accepting even 1000 W/cm2-power densities. POC's innovative module is based on a combination of a pulsing thermoelectric pump with an array of miniature heat pipes. In Phase I, POC will demonstrate an electrically enforced thermal superconductor for power dissipating devices. In Phase II, an engineering prototype BOTEC will be developed. The proposed Binary Oscillating Thermoelectric Chillers, both thermoelectric and double-phase based, will extend the current field of thermal management and cooling technologies for unmanned underwater vehicles and other compact platforms (missile, UAVs, state wide). They will improve integrated heat transport systems, which are essential for numerous Navy platforms and civilian vehicle applications. BOTEC-based cooling systems also will have numerous applications in computers as well as in control, communication, and measurement devices. They can replace the conventional vapor based heat pumps, and they can be implemented directly on microchips. These thermoelectric coolers will find many applications in the market of commercial refrigerators.

Title:Digital Array Radar Processor (DARP)
Abstract:Coherent Logix, Incorporated (CLX) proposes to develop concepts and design approaches that substantiate an achievable, highly parallel signal processing technology for DAR applications. This will enable the execution of real-time beamforming and pulse compression algorithms. In the Phase I program, CLX will implement real time wideband adaptive beamforming and pulse compression algorithms on it''''s new innovative microprocessor architecture, HyperX. HyperX is a revolutionary new digital signal processing technology based on the culmination of years of research and development in embedded processor architectures and hardware solutions to provide fast parallel processing of imaging and algorithmic data. The HyperX technology provides a dynamically reprogrammable, portable, and extremely power efficient solution. This development will provide the Government with a new signal processing technology that will execute real time wideband digital array radar algorithms. The core signal processor technology is adaptable to all facets of communication and image signal processing. The target market for the algorithms and software/hardware technologies being proposed is initially the Government military. Although the SBIR topic is intended to address the radar needs onboard ships close to shore, there are numerous other military operations where computation intensive algorithms need to be used for target discrimination, target classification and automatic target recognition in an environment with strong land clutter, man-made sources of EMI (other radars, cell phone towers) and jamming signals. We do not know at this time the size of the military market other than that it is significant. Our business development approach will be to team with a strategic partner well established in providing military radar systems and knowledgeable about shipboard requirements. Coherent Logix will focus on developing and manufacturing the digital signal processor, and either develop in-house or team with another company to develop/license the algorithms. Coherent Logix will sell the component assembly to our partner to integrate into the radar electronics. We would most likely need to work through several additional partners in order to address other high resolution, robust radar military applications. The digital signal processor software and hardware that will be developed is also applicable to the commercial markets where there is a predicted explosion of video signal volume over the next decade, including such consumer products as digital broadcasting, personal video recorders, HDTV, advanced medical imaging and video enabled PDAs. Coherent Logix will initially target the digital television market for MPEG processing, image format conversions, and signal processing to address the multi-path and Doppler effects associated with implementing the ATSC 8-VSB demodulation standard.

Title:Advanced Digital Array Radar (DAR) Adaptive Beamformer and Pulse Compression Processor
Abstract:Morpho Technologies proposes a DSP architecture for Advanced Digital Array (DAR) adaptive beamformer and compression processor, based on its novel reconfigurable DSP technology. During phase I of the project the MS1 architecture will be investigated to meet the requirements of the next generation DAR adaptive beamforming will be proposed. This process includes detailed study of the system requirements as compared to the capabilities of the current generation of MS1. Based on this study, changes to the the MS1 architecture will be proposed to efficiently serve the above DAR application. The modifications will be based upon a better processing speed per unit power (GOPS/Watt) while minimizing the chip area. An initial conceptual design of the enhanced MS1 will be presented by end of Phase I, which can be considered as a novel reconfigurable DSP processor platform customized for the next generation DARs. The proposed reconfigurable architecture is an excellent platform for adaptive radar applications as it combines parallel processing cabability (to increase the real time throughput) with reconfigurability. The reconfigurability greatly helps the design as the algorithms can change and dataset size varies depending on the application. In addition the reconfigurable cells (RCs) of the reconfigurable structure can perform pulse compression/decompression at very high processing speeds. Potential commercial applications are the adaptive antenna processing used in next generation cellular (e.g. WCDMA), WLAN, and other wireless technologies. In addition, the reconfigurable nature of MS1 along with its parallel structure makes it a appropriate technology in many wireless applications with soft transition or switching between physical layer applications including Software Defined Radio (SDR).

Title:Advanced Digital Array Radar (DAR) Adaptive Beamformer and Pulse Compression Processor
Abstract:Adaptive Digital Array Radars (DARs) promise significant sensor performance breakthroughs when antenna arrays become sufficiently large to achieve useful gain and directivity. Recent electronics technology advancements have progressed to the point that adaptive DAR sensors will soon support operational requirements for many important US Navy applications. A Reconfigurable DAR Processor (RDP) addresses several DAR-related needs: a test bed for pulse compression (PC) and adaptive beamforming (ABF) algorithm development; field testing of digital array antennas; and a complete space-time adaptive processor (STAP) for first generation adaptive DARs. The proposed design employs a large network of FPGA-based DSP nodes distributed over several line cards interconnected by a full serial mesh backplane. Notional designs at the chassis level, line card level and DSP node level are presented. The design uses two levels of firmwave reconfiguration: system maintenance and functional upgrades; and rapid reconfigurations allowing on-the-fly STAP re-functioning to follow radar mode changes. An efficient firmware development methodology facilitating DSP element re-use is presented. Phase 1 activities: review of PC, ABF and other DAR-related STAP functions; analysis of a calibration concept for non-adaptive beamforming that simultaneously generates accurate ABF steering vectors; RDP requirements definition and system design; development of a DSP firmware design library. The Reconfigurable DAR Processor (RDP) provides a flexible platform that can host a wide range of systems that process high-speed input data streams, generate high-speed output data streams, perform large-scale computational tasks, or any combination thereof. Our plan is to use the RDP on several future R&D efforts primarily for DoD customers, and secondarily for targeted commercial and other-government opportunities (such as telecommunications) arising from our commercialization strategy. One DoD customer has been identified that is interested in providing Phase II Fast Track matching funds.

Title:SE-WAVE: Systems Engineering Wide Area Virtual Environment
Abstract:As Navy systems grow in size and complexity, engineering teams struggle to stay connected to a degree that enables them to share engineering data. It is just not reasonable to force everyone to use the same tool set, yet a common model of the data is essential to uncover problems and inconsistencies early in the development life cycle. The lack of large scale systems engineering ultimately results in battle group interoperability problems. Modus Operandi proposes a Systems Engineering Wide Area Virtual Environment (SE-WAVE) to connect engineering teams and provide a systems engineering point of view over a diverse set of engineering applications. The virtual object-oriented repository connects the applications to provide a common model of the data without requiring engineers to switch to a new tool set, and without disrupting day-to-day operations. This approach also makes it easy to adopt incrementally and to evolve to support new applications. With this seamless integrated view, systems engineering analyses such as traceability and consistency checking become possible on a larger scale. SE-WAVE's human-centric design features make it easy for the users to get full value from this network of integrated information. SE-WAVE benefits the Navy by identifying system problems earlier in the life cycle. Requirements-related problems are increasingly more costly to repair the later in the life cycle they are identified. SE-WAVE enables requirements tracing and consistency checking in situations where the engineering data is not contained within a single integrated tool suite. The SE-WAVE approach is well suited to geographically distributed teams that need to share information from diverse data sources. It can be deployed more quickly, and with lower risk, than solutions that require teams to adopt a whole new set of applications, or that force data into a single repository. In addition to collaborative systems engineering, expected commercial applications of SE-WAVE in the Integrated Workgroup Solutions market include contract performance management with metrics from integrated enterprise data sources, and application of the discipline of requirements management to needs such as workforce training and certification. In the federal marketplace, SE-WAVE technologies can be used to enable sharing of information from diverse multi-agency legacy data sources for homeland security.

Title:Advanced Engineering Application Integration Technologies
Abstract:Major weapons systems as well as civilian manufacturing, transportation, health care, and information management systems continue to increase in both magnitude and complexity. The size and scope of the coming generation "systems of systems" represent an enormous challenge to the capabilities of today's development teams and their methods, processes, and tools. This project proposes to leverage Trident's InterchangeSE technology and advanced research in Java Jini and XML schema for automated discovery of tools/data source data types and capabilities and semi-automated integration of systems engineering information. The significance of such an integration advancement will be demonstrated by dynamically integrating three tools with overlapping data sets - Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) architectures, that are new to the environment with data from three existing tools/domains (requirements, implementation and cost). The common/overlapping architecture data set and corresponding Object Oriented Schema will be based on the C4ISR Core Architecture Data Model (CADM). Successful completion of this project will represent a significant advancement in the integration of engineering applications while improving the performance and overall quality of the systems produced. This approach will go far beyond its existing enterprise application integration technology by providing a much more dynamic, asynchronous, flexible, real-time integration mechanism. This environment will provide an open, ubiquitous, distributed environment that will not only integrate existing and future tools and legacy databases but also provide configuration management, asynchronous integration, advanced analytical and visual capabilities, as well as a flexible scalable environment based on Trident's InterchangeSE product.

Title:Metal Passivization to Resist Corrosion
Abstract:Hydrogen Plasma generated by tap water and sodium bicarbonate is designed to clean metals of oxides and organic contaminants, including paints, leaving the surface passivated against corrosion and with an anchor profile that enhances coating adhesion. The removal of mill scale results in two distinct benefits: a.) enhanced adhesion characteristics and b.) surface passivation against corrosion. Utilizing the same process, conductive metals, such as zinc, zinc/aluminum, copper, copper/nickel, and nickel can be applied to a metal substrate. Theoretically any conductive metal can be applied with the plasma process, however; only the metals listed above have been tested to date. Two key areas have potential benefits from the use of the plasma technology; 1.) metal cleaning which is cost effective, environmentally friendly, creates an active keyed surface and causes passivation against corrosion, 2.) metal coatings, including multi-layered coatings, alloys or combinations of pure metals and alloys. In both of these key benefits areas, all segments of industry, military and private, will benefit and in particular wherever acid is used as the cleaning agent for metals and where there is a need to perserve fresh water. Within the time frame for this Phase I program, several areas of commercial development will be underway. First, wire, rod and capillary tubing; industrial units for this industry will be introduced by the end of the first quarter 2003. Second, narrow width continuous strip cleaning and coating will be in development by the end of the second quarter 2003, along with the cleaning and coating of tubular goods. Third, by the end of the third quarter 2003, the technology will be intorduced into the high-speed strip steel industry for cleaning and coating, including the stainless steel industry.

Title:Metal Passivization to Resist Corrosion
Abstract:Development of new, low-cost, environmentally friendly, anti-corrosion system to provide passive protection of steel structural features is critical for many industries including ship construction. This problem is especially important in case of protection of limited spatial areas associated with manufacturing and repairing processes such as joining, fastening, welding, etc. Currently used shipbuilding preservation systems are based predominantly on polymer coatings. Polymer coatings cause many problems because they perform very poorly when heat is applied. This proposal presents a new technology, still under development, that looks promising to apply high quality, corrosion resistant metal coatings, in limited spatial areas which react to heat much the same as the steel base metal does. The technology is based on using the Cold Spray process avoiding undesired effects inherent to polymer based systems as well as conventional thermal spray methods. A brief summary of the problems associated with existing polymer and thermal spray coating technologies is presented, a new concept of metal passivation based on using the Cold Spray process is described. The ability of Cold Sprayed corrosion resistant coatings for manufacturing and repairing different parts including spraying in field conditions on limited spatial areas would have numerous industry and military applications. Applications where low-cost, high quality, environmentally friendly, corrosion resistant coatings are demanded include aerospace, automotive, transportation, chemical, construction, oil and gas, shipbuilding, and others. Additionally, a market to sell equipment to spray corrosion resistant coatings using the Cold Spray process would emerge to compete with many of the polymer (paint) and thermal spray technologies stimulating the economy.

Title:Metal Passivization to Resist Corrosion
Abstract:Localized corrosion of painted steel structures often initiates manufacturing or maintenance irregularities associated with metal joining, cutting or extreme forming. The restoration or introduction of highly controlled passive protection is viewed as a means of reducing or eliminating maintenance activities associated with painted steel structures. This project proposes the development of a portable, high quality and environmentally friendly system to provide localized laser cleaning, passive corrosion protection through laser cladding, and final polymer coating of steel structural features of limited spatial extent in one operation. This will be achieved by combining and optimizing existing laser-assisted processes to address the issue of metal passivization while controlling the burn-off of painted fabricated structures. A mechanical design for the portable system will be developed with a special emphasis on issues related with the deployment in a shipyard. This system will be benchmarked against currently used coating systems. Besides the manufacturing of new ship structures, the maintenance and repair of the Navy fleet is a well-known critical issue. The existing cooperation between Visotek, Fraunhofer and Bender Shipbuilding in other programs and the network of each of the involved parties, ensures dissemination of the results to other programs and stimulation of future programs. The US Air Force, Marine Corps, Army, NASA, Navy and major defense contractors such as Boeing and Lockheed Martin, shipbuilders including Bender and Northrop Grumman are all major stakeholders in the development of a portable laser system that cleans and provides corrosion resistance. The program, if continued in a Phase II will result in two products that have many derivative applications besides the one described in this proposal. First, the optics combining laser cleaning, laser cladding and sealing builds the base for use in body-in-white assembly and structures in the automotive, construction, aircraft and other military industries. The US Air Force, Marine Corps, Army, NASA, Navy and major defense contractors such as Boeing and Lockheed Martin, shipbuilders including Bender and Northrop Grumman are all major stakeholders in the development of a portable laser system that cleans and provides corrosion resistance. Secondly, the high power diode laser and the fiber laser are advanced laser systems that can either replace existing laser installation or open new markets due to their enhanced performance and low cost of ownership.

Title:High Performance Secure Shpboard Network for Wireless/Wired Connectivity
Abstract:A need exists today in both military and commercial systems for low cost, high performance, secure information processing. Data-intensive communications systems and content-rich commercial wired and wireless products require secure data flow at increasing levels of throughput. Strategic military objectives as well as company-sensitive commercial applications necessitate a design and implementation process that thwarts the compromise of critical wireless information or data, following loss or capture of the system and its components. Both wired and wireless data flows will benefit from a well-planned architecture of security algorithms and data compression, resulting in high-speed communication within the system that is impervious to eavesdropping, external interference, and any other countermeasures short of destruction of the system. The well-planned architecture can withstand an adversary having knowledge of the security and compression algorithms being used, and even possession of the system hardware, yet still the adversary is unable to decode the data that is being securely transferred throughout the system or to reverse-engineer the critical components. Our proposal focuses on the development and optimization of a tamper-proof system that fully integrates advanced encryption, fine-tuned data compression, scalable key management, critical security parameter management, and a high speed standard interface for rapid integration with existing military and commercial systems. Phase I deliverables will serve as a blueprint for development of a state-of-the-art, comprehensive system for secure, reliable, tamper-proof, high-speed data communication. It will be applicable to both military and commercial environments where content-rich data is required to be transferred in a reliable, secure manner. It is expected to have wide application in areas such as Federal office buildings, DoD assets, Force Protection efforts, Homeland Security, operational forces, inter and intra ship communications, hospitals, emergency response centers, space stations, underground command bunkers, nuclear plants, and in other high-value industrial assets and processes. A successful approach will identify and solve the technical challenges faced in making the high-speed encryption/compression solution with advanced cryptographic key management mechanisms viable not only in a ruggedized, secure, tamper-proof solution for Navy shipboard, but also presented in a high-volume solution designed for commercial manufacturing.

Title:High Performance Secure Shipboard Network For Wireless/Wired Connectivity
Abstract:The objective of this research is to develop and demonstrate affordable secure, high performance solutions to enable shipboard use of wireless sensors, computers, devices and applications that transmit data and information via RF/IR over wireless/wired LANs. Our approach is based on recent advances in networking technology such as VPNs, active networking and industry standard protocols. Drawing on these commercially available products and standards, Trident will specify, develop and test an innovative secure environment for use in a shipboard setting. This environment will facilitate the use of wireless sensors, computers, devices and applications, and will enable the Navy to make use of commercial wireless LANs and devices. A secure wireless shipboard environment will provide a powerful medium for using wireless sensors, computers, devices and applications. Given a secure environment, the Navy can use the wireless medium to push/pull data and applications to each sailor, regardless of their physical position in the ship. Applications such as log taking & analysis, maintenance related tasks, safety and damage control evolutions, will all be made easier by the free flow of secure data. Sensors, both equipment monitoring and operational, could take advantage of the secure wireless network to provide real-time data on the state of the ship and its systems.

Title:FIBER REINFORCED CERAMIC RADOME MATERIAL WITH IMPROVED RESISTANCE TO THERMAL SHOCK, HIGH TEMPERATURE, AND EROSION
Abstract:For this research, Advanced Cerametrics, Inc (ACI) proposes to combine its patented viscose suspension spinning process (VSSP) for manufacturing ceramic fiber, with conventional slip casting, to develop a low cost and economically scalable fiber-reinforced ceramic matrix composite (CMC) radome material. The proposed CMC is high-celsian barium aluminosilicate (BAS) matrix reinforced with continuous Si3N4 fibers. Green Si3N4 will be made by VSSP and then made into plate-shaped preforms consisting of unidirectional fibers. The fiber preforms will be infiltrated with the BAS powders by slip casting. The green composite bodies will then be fired to high densities and will consist of high celsian matrices reinforced with continuous Si3N4 fibers. The fibers are expected to impart improved mechanical properties (increased toughness, hardness, low and high temperature strength and wear resistance), while still maintaining the good dielectric and thermal shock resistance of celsian. The mechanical, thermal and dielectric properties will be fully characterized as a function of fiber diameter and volume fraction. Flat plates will be made in Phase I, and prototype cone shaped radomes by the end of Phase II. The Phase I goal will be to demonstrate improved resistance to thermal shock, high temperatures and erosion for the composite versus current monolithic BAS and mainstay ceramic radome materials. ACI intends to apply for the Phase II SBIR Fast Track. In addition to radome applications there are several potential commercial applications in which Si3N4 fiber reinforced BAS could find use. For example due to their expected good high temperature mechanical properties and lower density, these composites can be considered as a replacement material for metallic components in the high temperature sections of gas turbine engines (e.g., in land based turbine power generators, high bypass engines and jet engines for commercial aircraft). Additionally, the electronics industry will benefit from the lower dielectric constant of the proposed composite, which could replace high dielectric alumina in high-heat-load, surface, mount technology electronics.

The proposed ceramic materials will have the improved strength, toughness and thermal shock capabilities required for this application. Additionally, they have been shown to possess a low and thermally stable dielectric constant, high rain erosion resistance and will be fabricated into radome shapes. ACR will develop the processing method for radomes using low-cost processing methods. ACR will also evaluate the infusion of the gelcasting slurries into a fibrous preform. This method is suitable for a number of different applications in propulsion and energy related applications for the fabrication of high-strength ceramic composites.

Title:Cerablak Matrix CMCs for Next Generation Radomes
Abstract:In this Phase I SBIR project, a low-cost oxide-oxide interface coating-free ceramic matrix composite (CMC) will be developed for radomes for next-generation high speed missiles. The innovative and key component of the CMC is a newly patented matrix material (CerablakT) based on aluminum phosphate compositions. The key properties of CerablakT relevant to radome applications is its low dielectric constant (range from 2.98-4 @ 4-13 GHz) and high temperature stability. Cerablak is derived from a low-cost and clear precursor solution with a low viscosity and high yield which is highly beneficial for efficiently fabricating matrices for CMCs. Excellent have been demonstrated for CerablakT matrix CMCs with Nextel 610 and 720 reinforcements. These properties include high composite strength, excellent compatibility with fillers and fibers, and high matrix density. In Phase I, CMC specimens will be fabricated using Cerablak matrices Nextel 720 fabric. Property evaluation will include dielectric constant of composite systems, RT tensile strength, and matrix density. Based on the results, a suitable CMC system will be selected for Phase II effort. In Phase II, ATFI will work with the Navy and prime contractors of radome systems to integrate the CMC technology. Radome materials with improved properties will aid in the development of next-generation high speed missiles. CMCs have applications as structural materials in high temperature corrosive environments. Low dielectric constant materials have many applications in electronics.

Title:Development of RBSN Based Materials for Next Generation Tctical Missile Rdomes
Abstract:Anticipated requirements for the advanced long-range anti-air missile systems require ceramic radome materials with superior mechanical and thermal properties, in addition to low dielectric constants and loss tangents in the appropriate electromagnetic spectrum . The severe environmental conditions generated during hypersonic flights (temperatures as high as 2800°F (1500°C), and extreme rain erosion conditions) place rigorous demands on ceramic radome materials. Under these conditions, current materials (Pyroceram 9606, fused silica, IRBAS etc.) will likely not be adequate. Development of improved RBSN based silicon nitride materials (RBSN+) is proposed to meet the new demands. This proposal addresses the development of new radome material(s) based on silicon nitride that would offer very good thermal, mechanical and rain erosion properties, which could be manufactured to net shape and therefore at significantly lower cost.

Title:Radome Materials & Process for Long Flight Duration-High Speed Missiles
Abstract:Conventional ceramic radomes materials have reached their performance and life limitations, predominantly due to more severe flight environments and targeting requirements for advanced missile systems, and the resultant increase in radomes materials property requirements. This problem has become exacerbated with the phase out of Pyroceram as a commercially available radome material, since alternate ceramics with similar performance capabilities are much more expensive and exhibit performance limitations. Alternate ceramics such as silicon nitride and IRBAS have been considered many times for radome applications; however, the combinations of high dielectric constant, high thermal conductivity, high machining costs, low production yields, and poor rain erosion in half wave configurations have driven the need to continue development of alternate radomes material candidates. This proposal presents a unique opportunity to develop low cost innovative manufacturing processes with the specific goal of applying technology previously developed under SMDC Contract DASG60-98-C-0027, under which Mentis Sciences, Inc. (MSI) developed and evaluated composite radome materials for RF, specifically Ka band applications. The ultimate intent of this effort is to evaluate these materials for X to W-band applications for future high performance missile platforms and offer the community a low cost alternative for these systems. Phase I results are expected to show that the proposed composite radomes can be used both as a replacement for Pyroceram and for advanced systems, with both lower cost and higher performance. Prior technology developments by the research team lead to these expectations.

Title:High Thermal Shock Resistance AIN For Infrared Window Applications
Abstract:A very attractive alternative for an IR sensor is an uncooled IR window, which can operate in the highly aerothermal environment of a surface-to-air missile. This program proposes to develop an uncooled IR window for IR sensors, which can operate in the aerothermal environment of a surface-to-air missile. The mild thermal shock parameter, R?, of aluminum nitride (AlN) is approximately one order of magnitude higher than the other infrared materials. The innovative idea in this program is to use unique powders and a special sintering aid to achieve a nanosized grain microstructure so that true transparency can be achieved. The transparent AlN developed in this program can be used to replace translucent Al2O3 for sodium and halogen lamp applications. It can also be used for IR missile domes, transparent armors, undersea submersibles, supermarket scanners, glass for Xerox copy machines and scanners, and optical lenses. This new material can have significant impact on the optical industry by replacing specialty glass and sapphire.

Title:Improved IR Windows for Severe Aerothermal Environments
Abstract:Current IR window materials, while offering good optical properties are often structurally inadequate in their ability to perform in ever more increasingly hostile environments. Optically transparent, hard ceramic materials such as spinel, ALON and sapphire while expensive to fabricate and finish are considered viable candidates against scratch and rain erosion and severe thermal environments. Pressureless sintering of spinel using little or no additives is being proposed as a low cost approach to producing IR windows and domes with exceptional strength and optical properties. Spinel transmits further into the MWIR than either ALON or sapphire and due to the significantly lower fabrication temperature and processing complexity, can be made at considerably less cost. Careful control of the pressureless sintering schedule allows grain refinement, with improved strength and thermal shock resistance. This research effort will establish a baseline processing protocol for net shape spinel domes and will establish cost estimates for future scale up. It is expected that the proposed pressureless sintering approach for spinel will lead to a significant cost reduction in the fabrication of future IR windows and domes. Conventional ceramic processing technologies such as slip casting may be employed enabling the low cost fabrication of ogives and other complex shapes difficult to fabricate by other low cost processing approaches. Additionally, the very near net shape capability will result in significantly reduced finishing costs over conventional grinding and polishing approaches. Transparent spinel products could become mass produced for such optical applications as fuses, small sensor windows, wear resistant transparent surfaces and thermal inspection IR lens and windows .

Title:Electronic Sensor Precision Feature Extraction Pre-processor
Abstract:With the ever increasing complexity and density of the threat environment anticipated to be encountered by today's and tomorrow's EW systems, the need exists for a reconfigurable and adaptive real-time pulse feature extraction processor with enhanced capabilities beyond that employed in most operational Electronic Support (ES) or Radar Warning Receivers (RWR). Automatic detection, identification, and classification of such systems is desired to ease operator workload in dense signal environments. The employment of a Feature Extraction Pre-Processor can be used to enhance a host Electronic Surveillance System's Emitter Track and ID capabilities using observable intentional modulation on pulse (IMOP) unintentional modulation on pulse (UMOP) features. Techniques employed in the development and integration of detection, measurement, and typing algorithms can be used to develop products to automate air traffic control operations, easing ATC operator burden and increase situational awareness. The anticipated benefits include a low-cost, reconfigurable device based on FPGA based COTS board technology. Other potential applications include, in addition to upgrades to currently fielded and new planned systems, a reduced size version for UAVs. Using the VHDL design code provided on this effort, custom higher gate density FPGAs or even more efficient ASICs could be used to achieve size reduction necessary for UAV ELINT applications. In addition, individual algorithms can be easily modified without entire cardset redesign. Finally, many of the algorithms developed or implemented herein can be readily applied to characterizing the external features of communication signals (e.g. COMEX), or to perhaps characterizing certain wireless or cell phone modulations for the purposes of identification and location to support Homeland Defense initiatives.

Title:Plasma Limiter: RF Mitigation Device for Radar and Electronic Warfare Systems
Abstract:The widespread use of communication devices and radar systems has made our society increasingly vulnerable to disruptive, high-power, short pulse electromagnetic interference (EMI) and high power microwaves (HPM). Significant advances in devices that produce these high-power, short pulses have been made in the US and abroad in the past few decades. As a result, the need for devices that can protect sensitive communications equipment from such disruption is greater than ever. The primary objective of the proposed Phase I program is the development of a S-band plasma limiter to protect RF electronics, specifically within radars and electronic warfare systems. The S-band plasma limiter has target specifications of 10kW power handling, <1 nsec response time, and <.5 dB insertion loss. The limiter will operate on the same principle as our X-band waveguide plasma limiter. The potential commercial market for plasma limiters as RF protection devices is tremendously broad and includes radar systems, telecommunications systems (including mobile phones), and DSTV. In the near term, marketing will be directed immediately towards the military sector to protect all air, land, sea, and space based radars with a focus on Naval high threat radar systems such as the Aegis platform AN/SPY-1 radars. The plasma limiter will be integrated into new radar systems and retrofitted into existing systems. Accurate Automation Corporation will work with leading defense manufacturers to bring to market low cost plasma limiters.

Title:Wideband Limiter Protector for radar and electronic warfare systems
Abstract:Naval vessels today are equipped with a large variety of electronic equipment for radar functions, communications, navigation, countermeasures, and others. Many of those shipboard systems operate with transmitters emitting thousands of watts of power in microwave frequencies, and the presence of high-power transmitters in close proximity to sensitive receivers. This proposal is addressed to the development of broadband microwave limiters using wide band-gap devices of those technologies suitable for applications in microwave frequencies, namely gallium-nitride (GaN). So far, the prospect of high-power microwave amplifiers using GaN devices has been investigated at length, but there has been only a limited study of application of those devices as signal control devices such as switches and attenuators and no reported studies of limiters and LNAs. The proposed program will be focused on development of limiters and LNAs for receiver protection. The Phase 1 effort will lead to a full assessment of capabilities of GaN microwave limiters and LNAs, definition of design goals for broadband limiters, LNAs and design approaches. The ensuing Phase 2 program will be focused on implementation the limiter design and demonstration of its capabilities. Successful implementation of limiters in MMIC form will protect sensitive shipboard receivers against both friendly radar emissions and hostile high-power microwave (HPM) threats. Rugged LNAs will further enhance the survivability of receiver front ends. Ultimately, limiters for receiver protection will find applications in all microwave equipment subject to potentially hazardous radiations, including commercial receivers for wireless communications and satellite receivers. Hittite Microwave Corporation has a history of limiter development of novel circuits for protection applications including stacking FETs in series to withstand high RF voltages, and a method of feed-back controlling attenuators for receiver protection. A method of implementing a MMIC notch filter was also demonstrated to suppress high levels of selected harmful radiation, and the limits of purely passive limiters based on conventional GaAs FET devices were investigated. Recent advances in wide band-gap semiconductors show a promise of devices with a high break-down voltages that may ultimately lead to integration of limiters into MMIC modules. GaN technology is an emerging technology for high power microwave components including amplifier and control components. While most GaN development is currently focused on amplifier components GaN may also prove superior for many control component applications such as high power switches and limiters as well as threat resistant LNAs. These components will find application in cellular base stations and other communications equipment.

Title:X-Band Radar Power Supply
Abstract:In Phase I, Diversified Technologies, Inc. I proposes to design and demonstrate a new flexible, modular multi-phase buck regulator power supply for use in phased array radars. The proposed design is substantially more efficient and reliable than either the transformer-coupled DC-DC converters or conventional buck regulators presently in use. Its use will reduce the converter's cooling requirements and enable the Navy to achieve the desired converter specifications of a power density of over 100 W/in3, efficiency over 90%, and a cost of less than $1 / W. The power converter will be based upon unique DTI high voltage buck regulator technology, demonstrated to be more than 95% efficient. In Phase II, DTI will refine the production design of the prototype Buck Regulator Power Supply and build a representative, subarray sized power supply system capable of providing at least 100 kW of power, at high efficiency, and at significantly reduced size and weight. Higher efficiency lessens the amount of power lost as heat within the converter, so the overall size and weight of the converter can be reduced significantly. For example, increasing the converter efficiency to 95% reduces the cooling load (and the supporting infrastructure) by a factor of more than four. In addition, multi-phase buck regulators can be built at power levels from a few hundred watts, to multi-MWs. There are no single points of failure within this design, so it has very high reliability at any power level. This new design opens a wide range of possibilities for driving solid-state phased array antennas. The converter can be built to drive a single T/R module or a full subarray. It can be located on- or off-array, without compromising system reliability. This flexibility allows examination of the optimal power converter sizing, taking into account size, weight (on- and off-array), efficiency, and cost.

Title:Radar Power Sources and Power Conditioning
Abstract:VPT proposes a high efficiency, high density, power converter that can support the requirements of wide band gap RF devices for Radar applications. The power converter will be modeled after VPT's existing 270V, half brick, 200W, 85% efficient design but will demonstrate significantly higher power density, efficiency, and operating temperature range by employing several new technologies. These include (1) new Silicon Carbide Schottky diodes (2) chip scale, embedded power packaging with advanced thermal management (3) ASIC controller, (4) high frequency magnetics design. In the Phase I research, VPT will perform the following: (1) develop power requirements for the next generation solid state arrays using wide bandgap devices, (2) perform the electrical design of a high frequency power converter with silicon carbide rectifiers that meets the requirements, (3) breadboard the design to verify the electrical performance, (4) perform a preliminary packaging design chip scale embedded power packaging in a full brick form factor, (5) perform a preliminary ASIC controller design. The goal is to obtain a power density of 200W/cubic inch, an efficiency of 92%, and an operating temperature range up to 125C. A 270V, high density, high efficiency, full brick power conveter can be applied to a number of military and commercial aircraft applications

Title:Permanent Magnet Motor Steering Gear
Abstract:The technical objectives of the Phase I effort are to develop two candidate designs for electromechanically driving the rudder on a DDG51 Flt IIA ship using a permanent magnet motor. Each candidate design will be analyzed to assess its feasibility with careful attention to failure modes, redundancies, contingency plans, estimates of mean time between failures and estimates of mean time to repair. Based on the analysis, a recommendation will be formulated regarding the feasibility of electromechanically driving the rudder. Anticipated benefits of using electromechanical steering to replace the existing hydraulic system include a reduction in acoustic noise and the vibrations associated with cavitation due to fluctuating pressures and valve actuations. In addition, system efficiency should be increased to eliminate the need for sea water heat exchangers. Further, improvements are expected in the relatively high maintenance cost of the system, as well as reducing weight and volume of the system.

Title:Permanent Magnet Motor Steering Gear for DDG 51 FLT IIA
Abstract:Permanent Magnet Motor (PMM) technology, already used in demanding applications by the U.S. Navy and by the oil drilling industry, may be expanded to replace electro-hydraulic steering gear on DDG 51 class ships. PMM steering can potentially provide such benefits as improved dynamic performance, reduced noise emissions, lower maintenance, higher reliability, and lower life cycle cost. The challenge in using a PMM as a rudder actuator is the requirement for very high torque at very low rotational speeds. This proposal describes three alternative PMM steering gear configurations that will meet this requirement. Each of these configurations will be evaluated on the following criteria: technical feasibility, dynamic performance, development cost, production cost, environmental standard compliance, power consumption, maintainability, and reliability. This evaluation will lead to recommendation of a PMM steering gear configuration for the DDG 51 FLT IIA. Commercially viable PMM steering gear will be of great interest to commercial and military shipbuilders. This research could also lead to improvements in PMM propulsion systems and other high torque PMM applications.

The project will also investigate a hierarchical fault detection, analysis and notification infrastructure that provides accurate and timely characterizations of faults and damage in complex distributed systems. The anticipated benefits and potential commercial applications include: * Rapid, and accurate, detection and analysis of faults in complex distributed systems. * Fault detection mechanisms that are easy to use and easy to integrate into commercial system management and resource management products. * Fault detection mechanisms for commercial distributed systems, including telecommunications, industrial control and manufacturing, transportation and medical systems. * Rapid, accurate and standards-compliant fault detection mechanisms for the Navy's Open Architecture, as well as for other defense and Government systems.

Title:Rapid Deterministic Fault Detection in Distributed Systems
Abstract:A novel approach to deterministic fault detection is proposed, based on the idea of augmenting component interface contracts with behavioral and timing semantic tags. Since the component interfaces are registered with the middleware infrastructure, violations of the interface contract semantics can be detected and managed by the middleware. The proposed solution integrates the common middleware communications models, including distributed-object, publish-subscribe, and group-ordered communication. It ensures fault-delivery guarantees, such as bounded detection latencies. This fault-detection approach can be integrated with commercially-available system management products to deliver a robust solution that meets a wide range of needs by distributed applications in both the commercial and defense sectors. The proposed effort will characterize faults and isolate contract semantics relevant to fault detection, define an integrated middleware communication model that is cognizant of interface contract semantics, develop techniques for integrating with commercial system-management products, and demonstrate a prototype implementation of the approach for selected fault conditions. The new approach will ensure fault notification guarantees (e.g., bounded detection latencies) previously not possible. Since it incorporates all three communication models, the solution will be able to handle fault situations previously not accessible, while providing an optimized and efficient implementation. In addition, the integrated middleware can keep better track of fault statistics for later analysis and debugging purposes. The integrated middleware will reduce the burden of fault detection on the application programmer by pushing the responsibility of fault detection and notification to the distributed infrastructure. This will free the application designer to instead focus on developing appropriate fault handling and recovery schemes. Furthermore, the faults detection will be easier to evolve and maintain as requirements change. If this work is not done, the current state of affairs with disparate middleware products will continue. Fault detection would not be guaranteed with bounded latencies. Fault semantics will need to be developed on a per application basis by the application programmer. Overlapping middleware semantics with their subtle differences will require careful handling, which lead to greater potential for errors. Opportunities for optimization will be missed, and internal middleware faults status will be made available on an ad-hoc basis. Thus, fault management will remain a thorny issue placing considerable burden on the application programmer and resource management algorithms.

Title:A Systematic Approach towards Detecting, Identifying, and Recovering from Component Failures
Abstract:The capability for recovery from failures is incorporated in almost every computer-based system that exists today. Yet, the design of fault tolerance mechanism for highly available, mission critical weapons systems is difficult, due to lack of coordination between fault tolerance techniques. In some situations the fault tolerance strategies interact with or even interfere with each other, possibly leading to a cascade of failures, resulting in overall system failure. These issues must be addressed when modern weapons systems are created from commercial components. The crux of the issue is identifying the characteristics of a failure - the particular guarantee of service that has not been satisfied. The ability to specify this failure service policy, with defined, documented, and measurable parameters, will enable an analytic approach to the problem. We propose to develop a dependability model for component interactions, along with an API that incorporates failure-relevant QoS parameters and supports implementations of the common failure detection strategies. We will use this model in the context of the Navy Open Architecture to investigate the feasibility of managing real-time, mission-critical applications using commercial enterprise resource management systems within the NOA resource management system. The key benefit of this work will be the reduction in complexity of developing failure management approaches for COTS-based weapons systems, with attendant reductions in time and cost of deployment. As the proposed work is leveraging COTS practice and standards, it will alos apply to commercial situations presenting complex failure management problems, such as digital control systems used in critical infrastructure management, and also large-scale distributed or grid computing activities.

Title:EasiStudioTM: An environment for the synthesis, analysis and verification of real-time systems
Abstract:Construction of real-time systems requires careful consideration to the software architecture at all layers and interfaces. We propose to build a highly usable framework that combines state-of-the-art analytical methods available for real-time system design with widely used commercial approaches to software design. This integrated framework, called EasiStudioTM, shall integrate the modeling, analysis and realization (code generation) of performance critical, object oriented systems. EasiStudio will utilize UML stereotypes and tagged values and allow modeling of components and interfaces augmented with performance specifications. A catalogue facility will enable COTS and custom components/classes to be reused consistently. Using these models, users can generate code targeted towards a supplied library. The library will include standards-based messaging primitives and distributed resource sets for guaranteed and bounded performance. Both the code generation and library will be designed for popular languages and platforms thereby supporting a wide variety of projects. In addition, users will be able to do performance analysis and generate analysis reports characterizing the ability of the system to meet its deadlines. Integration with selected third-party tools will provide both high-level and low-level debugging support. EasiStudio will be scalable to support a large number of components and provide a visual, hierarchical organization facility. In U.S. defense systems, fly-by-wire avionics, process control, nuclear power control, automated manufacturing, air traffic control and medical systems, life-threatening situations can arise if failures occur due to the misuse of reusable object-oriented software. The EasiStudio framework will maintain, model and analyze the timing and reliability properties of software components and enable the disciplined development and reuse of object-oriented components in the design of such systems.

Title:Interface and Tools to Support Integration of Hard- and Soft-Real-Time Software Components
Abstract:Embedded computer systems play increasingly important roles in supporting the modern war fighter. The software on these systems tends to be organized as hierarchical layers, for which the lowest layers have hard-real-time and demanding throughput requirements. In the highest software layers, the software generally needs to be highly functional and flexible, but usually does not have real-time requirements or severe memory limitations. Intermediate layers in the hierarchy tend to demand intermediate levels of performance and compliance with less demanding levels of real-time, such as soft-real-time or firm-real-time. Between software layers, developers must engineer interfaces that provide efficient communication and coordination without allowing software at one layer from compromising the integrity of software running at other layers. This SBIR proposal addresses issues in the design and implementation of high-performance, secure and portable interfaces between layers of hierarchical software architectures. Based on the results of this research, prototype interfaces and tools to support the verification of compliance with interface requirements will be designed, prototyped, and evaluated. This technology benefits all developers of mission-critical embedded systems, including traditional mil/aero markets, but also automobile control, network infrastructure control and data planes, and rail transport. These technologies are especially valuable to the community because Ada suppliers are phasing out support for their Ada compilers, and the C and C++ languages do not scale as well to large software systems, especially systems that involve the mix of hard-real-time and soft-real-time components.

Title:Practical Test and Verification of Component Behavioral Characteristics
Abstract:While test and certification of current Naval systems based on federated architectures is a well-understood process, existing methodologies will prove inadequate when applied to component-based distributed real-time systems employing dynamic resource management in a heterogeneous environment. This inadequacy in testing and certification can be addressed by the development of testing methodologies that characterize component behavior through specification of assertions on both functional and non-functional behaviors. We propose to investigate extension of the Assertion Definition Language tool to provide verification of non-functional as well as functional behavioral characteristics of a component as the foundation of an assertion-based testing methodology. The existing ADL implementation already has many of the attributes necessary to satisfy a systematic functional verification methodology. We will identify enhancements to the ADL specification language and test generation capability to include metrics for non-functional characteristics as part of the formal grammar that expresses the assertion specification of an interface''s behaviors. Targeted characteristics will focus on hard and soft real-time behaviors such as deadline, latency, throughput, and jitter. This approach will be applicable to multiple system design patterns, is systematic, and provides a high degree of automation making the process auditable and repeatable.

Title:Applying Fine Water Mist (FWM) Technology to DDG 51 Class Ships
Abstract:It is proposed to conduct research to determine optimum mist-delivery/generating technology (i.e. pump, accumulator, hybrid gas generator, or gas pump unit/nozzle type) and system architecture that will afford the requisite fire protection for the current halon protected spaces (machinery, turbine enclosure, and flammable liquid stowage areas). The practicability for replacing existing light-hazard sprinkler systems will be studied within overall water mist fire protection strategy. This proposed contract will develop a cost/benefit analysis depicting affordability, space, an weight impact prior to delivery of final concept design. The Phase I will address the feasibility of determination and development of an affordable implementation of water mist technology. The Phase II will further develop and optimize the prototype of the technology and demonstrate its effectiveness at a land-based facility. During the Phase III Beltran will develop a full-scale system and install it on a DDG 51 Class ship. Beltran proposed to work with Bath Iron Works, a General Dynamics Company, in Phase I, II and III. BIW Advanced Technology Division will support Beltran's fine water mist fire suppression development efforts throughout the SBIR process by providing marine engineering integration expertise and DDG 51 Class Destroyer specific design requirements. The imminent lack of availability of halon fire suppressants has sparked efforts in developing alternative fire fighting agents and delivery systems. Water mist fire suppression systems are potential replacements for Naval fire suppression systems on DDG 51 Class ships, as well as other ships. Also, this technology will have application for other military systems, industrial applications and aviation, such as commercial passenger aircraft.

Abstract:Water mist fire protection systems offer an attractive alternative to halon-proteted shipboard hazards. Well documented performance characteristics, combined with evolving commercial hardware technology, offers the opportunity to develop a retrofit suppression package for Navy ships. This Phase I proposal describes the feasibility study needed to advance this concept to prototype development and ultimate commercialization. Variables to address in the feasibility study include fire extinguishing performance as a function of nozzle design, system pressure flow rate, and actuating mechanism. Shipboard integration requires an architectural assessment of fluid power supplies, agent storage, valving, control systems, and survivability. There is the potential to commercialize a retrofit water mist fire protection package for application to a number of military/government ship platforms.

Title:High-efficiency power amplifier for multipurpose portable radio
Abstract:There is a need for a portable command-post transmitter that can be deployed in an emergency situation. Interoperability among the different military services and civilian agencies is required. Consequently, the transmitter must operate at all frequencies from 200 MHz to 3 GHz. It must also be capable of generating a wide variety of different signals. The proposed phase-I program will investigate the feasibility of a high-efficiency transmitter for this purpose. The proposed transmitter will be based upon a combination of a high-efficiency RF-power amplifier (PA), high-efficiency modulation technique, and electronic tuning. The high-efficiency RF PA ensures the maximum efficiency at peak output, while the modulation technique ensures that efficiency remains high for all signal amplitudes. Electronic tuning allows the transmitter to maintain optimum performance at all frequencies in its band of operation. This technology will enable small, light-weight radios capable of operating over a wide range of frequency and for a long time from a single battery. Military applications include airborne jammers and portable communication transceivers. Similar benefits are possible in a variety of commercial applications. Cellular base stations have similar output power and frequency range, but the average efficiency of current transmitters is no more than 10 percent. Application of this technology can increase the output power by 20 percent and reduce the power consumption by a factor of 4 to 6. The resultant transmitter will not only cost less to buy, but also less to operate. Broadcast transmitters and a variety of communication radios can also benefit from this technology.

Title:Improved Efficiency Broadband Amplifiers
Abstract:Transistor Power Technology, Inc. (TPTI) is proposing a program to develop a cost effective, solid state, linear, 200 watt amplifier, with an instantaneous bandwidth of 200 to 3000 MHz.The proposed amplifier is designed to serve in a military mobile communication environment driven by multi mode transmitters that operate to complex spread spectrum modulation requirements. The broadband capability combined with an efficient design will simplify mobile system logistics. TPTI's proposed low risk solution was structured to maximize the technical milestones in accordance with the allocated schedule. We are confident of achieving the proposed goals because of the vast experience of our technical personnel on similar programs. TPTI is proposing to investigate two parallel approaches that will insure the successful accomplishment of this program. The first uses one gain block. The second multiplexes two gain blocks. Simulated analysis is provided to show feasibility of both approaches. During the first six months of Phase I of this program, TPTI will perform simulation and trade-off analysis and verify performance of the proposed building blocks. TPTI is also proposing, under the option period, to integrate and test a quarter system building block, which will facilitate a smooth and confident transition to Phase II. Broadband communications.

Title:Short-Duration Manually-Driven Electrical Power Sources
Abstract:Typically emergency communications occur under less than ideal conditions such as natural and man-made disasters. Limited power sources, quick response times, and uncertainties as to communications systems encountered (used by other responders and local commercial systems) emphasize the importance of developing and deploying efficient and robust short-duration power sources capable of interfacing with a variety of equipment. This development will provide users a short-term capability to deploy and continue to operate various equipment requiring power sources up to 100 watts. This program will develop a lightweight, compact, short duration, manually charged, electrical power supply which utilizes compressed air as the energy storage medium. This unique approach will provide a very lightweight, compact system, that is extremely portable with a long shelf life (>25yrs) and can easily be expanded to increase its energy storage capacity. The manual generator will find application as an emergency temporary power source. It's compact lightweight design is very portable, and ideally carried by soldiers, emergency workers, on fire trucks, ambulances, airplanes, or wherever emergency equipment is needed. The compact design will make it an important asset to the soldier of the future who is heavily dependent on portable electronic equipment that is useless once the batteries are drained.

Title:High-Output Human-Powered Generator
Abstract:The feasibility of a miniature manually-driven BLDC power system will be investigated. The combination of newly developed high energy density magnetic materials, efficient low gear ratio transmissions, and switching converter electronics will be applied to generate high electrical power. Preliminary results show that 100-200 watts could be generated in a very lightweight unit at controlled output voltages and currents. The power system will be able to safely recharge batteries at high rates, or drive mobile electronic devices directly. A successful result would provide unlimited field electricity to troops engaged in protracted operations in remote locations. No fuels, maintenance, disposal, shelf life, or logistics would be required. High efficiency operation would minimize wasted effort. Troops would retain their mobility and operation of devices like night vision, communications, GPS, laser targeting, and data display/computers. The chargers would also address the $60B commercial battery market. Consumers and civilian emergency workers could manually charge devices like laptop computers, cell phones, GPS, audio/video, radios, flashlights, etc. Commercialization will also improve product quality and lower costs for future military procurements.

Title:Ultra-Wideband Impulse Radiating Antennas and Discones
Abstract:Ultra-Wideband antennas are a critical component of Ultra-Wideband communications and surveillance systems. Such antennas must cover a bandwidth of 20 MHz to 4 GHz, be omnidirectional, and be convenient to transport and deploy. We consider here how to modify existing two antennas, the Impulse Radiating Antenna (IRA) and the discone, to achieve those goals. Commercially available IRAs already have demonstrated effective operation over the entire frequency range. Normally, IRAs are directional antennas, but a circular array of four of these devices will form a single omni-directional antenna. Such devices can be built from small 18-inch diameter umbrella-like reflectors, so the array can be integrated into a small compact package. We will also consider a collapsible loaded discone. Commercially available discones do not cover the needed frequency range and are not portable or deployable. We can improve the low-end response by adding distributed resistive and inductive loading to the antenna. We can improve the high-end response by more carefully manufacturing the apex. We can make the discone convenient to deploy by making it collapsible, either in the form of an umbrella or by using tent-pole assembly. This research will lead to two Ultra-Wideband antennas that operate between 20 MHz and 4 GHz, a circular array of IRAs and a collapsible loaded discone. A prototype design of the circular array of IRAs will be built and tested during Phase I. Design calculations will be performed on the discone during Phase I, and it will be built during Phase II.

Title:Low Profile Wideband Self-Structuring Antenna
Abstract:This proposal requests funds to pursue development and demonstration of a Self-Structuring Antenna (SSA) system to meet Navy requirements for a low-drag mobile wideband antenna. The SSA is an entirely new class of re-configurable antenna that employs advanced search algorithms to assure optimal performance regardless of the environment or signal conditions. The SSA can be constructed on a lightweight, low profile, and flexible material to provide a higher performance alternative to fixed geometry antennas. The adaptable nature of the SSA allows it to operate over a wide frequency range and meet diverse mission requirements without incurring large upfront design costs. The smart algorithms operating in near real time allow the antenna to provide optimal performance even when the antenna has been partially damaged. The ability to reconfigure an antenna in near real time using our Self -Structuring Antenna system will: enhance the likelihood of constant communications between military, commercial and civilian responders using diverse frequency bands in emergency situations; increase likelihood that communications can be maintained if the antenna is damaged by misuse or hostile activity. Potential commercial applications are numerous and include: antennas for automobiles, aircraft, cellular phones, wireless networking, HDTV, satellite radio, personal wireless devices.

Title:Fractal-like Log-periodic Ultra-wideband Antennas
Abstract:WaveBand Corporation (WaveBand) proposes to design and develop for communications applications a new type of ultra-wideband antenna system operating within the frequency range of 20 MHz to 4 GHz. The requirements of both wideband and high-power operation will be satisfied with two modified fractal-like log-periodic antennas integrated into a single system. We expect the antenna to be of excellent radiation efficiency (so it can be used for both transmitting and receiving), of reduced size, thus capable of being mounted on a vehicle, extremely light-weight and compact, easy to manufacture, therefore low in cost. The proposed antenna system will provide a perfect match to communications equipment mounted on a movable platform. Since the required frequency range is extremely broad, a system of two antennas, similar in structure but different in size, operating, respectively, in the low- and high-frequency portions of the range, will be considered as a possible solution. Due to the fact that the radiating elements will be based on self-similar (fractal-like) structures, the size of the antenna can be greatly reduced. Moreover, because the proposed antenna system involves a metal film deposited on a thin dielectric substrate, it can be folded in half, providing for easy storage and deployment. Low cost reduced-size antennas have a large number of civilian and dual-use applications in the realm of RF and microwave antennas, devices, and systems for communications and signal collection needed in the broadband communications market.

Title:Development of New Program-Specific Geometry Models
Abstract:The Real-Time Champ (RTC) infrared (IR) scene generation model created by Kinetics, Inc. has been acknowledged to provide unique technological advancements in IR scene rendering. In this Phase I SBIR proposal, Envisioneering proposes to identify specific aircraft models that are of near-term need by the user community for inclusion in the RTC database, investigate the level of detail required in each model to ensure reasonable computational times without compromising details that might affect the accuracy of model predictions, and review the interfaces of end users to ensure compatibility. Specific areas of investigation will include the aircraft geometric representation, the thermal model, the plume model, optical/IR properties, and validation of the accuracy of the model. There currently are several users of the RTC IR scene generation model. This SBIR study will result in an IR code with additional high-value targets with accurate 3D physical drawings, which will not bog down the processing speed of the hardware-in-the-loop simulator. This increased capability is expected to expand the use of this code among U.S. DoD and NATO agencies, military aircraft designers, and commercial aircraft designers. Envisioneering has been a key member in accomplishing this on other IR modeling codes.

Title:Development of New Program-Specific Geometry Models
Abstract:One of the requirements for evaluation of infrared sensor systems, counter measures and target detection algorithms is rapid and efficient signature generation for target/background scenarios. Fast, accurate simulation codes (Real-Time Champ (RTC)) exist to render target signatures, however development times for computationally efficient, accurate models and input databases to these simulation codes are unnecessarily long. Development times could be shortened if a system were available that could: (1) import 'older' engineering diagrams and new electronc "CAD" formatted files, and (2) allow them to be manipulated, rendered and viewed, providing the analyst the ability to iterate on the model until a satisfactory compromise was made between detail and accuracy. In this effort, Surface Optics Corporation (SOC) proposes to develop this system by integrating RTC with an off-the-shelf commercial CAD package, leveraging off the well-developed capabilities already in the CAD package for manipulating models. SOC will add the ability to: (1) assign appropriate material optical and thermal properties, and (2) by integrating RTC into the design package, allow the analyst to examine the effects to changes in the model on the signature of the vehicle in a matter of seconds without ever leaving the design software. The benefits of this effort would be a significantly enhanced simulation capability for the evaluation of advanced sensor systems and support for hardware in the loop testing. Faster turn-around times would aid in both the quality and breadth of systems to be evaluated.

Title:Easily Retrofitted, Active Noise Cancellation System
Abstract:Foster-Miller proposes to develop an easily retrofitted, Active Noise Cancellation System (ANCS) for reducing the external noise of large transport and multifunction aircraft during takeoff and landing. Billions of dollars have been spent relocating people from around airports in which the average noise level is 65dB or greater (1). Therefore any easily retrofitted improvements that can be made to reduce the external noise footprint during take-off and landing of aircraft, without harming the aircraft performance, will result in large cost savings for the U.S. Navy. Aircraft structural modifications or hushkitted aircraft have been tried with mixed noise abatement results. The Navy has a need to develop a noise reduction system that is cost-effective, easily retrofitted onto the current turboprop and turbofan aircraft, and that is low in weight and power consumption. Foster-Miller proposes to use an active treatment in the shroud of the engine inlet to control the reflected sound emanating from the vanes of the inlet fan. Phase II will focus on conducting a limited field demonstration of prototype. Our team includes experts in acoustic modeling and will include an aircraft engine manufacturer. (P-030132) Successful development of easily retrofitted acoustic noise reduction technology would have broad application to commercial aviation. The implementation of this technology would save billions of dollars that would have been spent relocating people away from the airport's >65dB zone. The development of this technology would also result in greater breadth in determining takeoff and landing profiles. The reduction of noise complaints would improve the public relations between the airport and the surrounding community.

Title:Acoustic noise reduction for large aircraft
Abstract:The feasibility of applying the following five in-house innovative active noise control technologies to suppress turbofan and turboprop engine noise will be investigated: (1) the design of a hybrid active/passive compact active control system, to reduce tonal and broadband noise radiated by rotor/stator interaction in turbofan engines, (2) the design of an active control system to reduce aircraft turbofan engine inlet/exhaust tone noise generated when rotor tip speeds become transonic, (3) to assess the feasibility of installing vane-mounted microphones for reference signal acquisition and quasi-near field duct-wall mounted actuators for anti-sound injection to suppress broadband rotor/stator noise,. (4) to develop active control double degree of freedom acoustic liners and (5) to assess the feasibility of installing active transducers to cancel radiated noise in specified directions to reduce noise footprint area. Development of a feasibile active control strategy to suppress excessive engine noise genrated from naval aircraft offers the opportunity to meet the Navy's target goals to reduce source aircraft noise levels by more than 20dB.

Title:Adaptive Turbofan Noise Active Control
Abstract:To address the U.S. Navy need to reduce turbofan/turboprop noise by more than 20 dB, Physical Optics Corporation (POC) proposes to develop an innovative hybrid active/passive Adaptive Turbofan Noise Active Control (ATNAC) system, consisting of a reactive noise suppression device plus a nonlinear active control module based on cascaded neural networks. By instant nonlinear adaptation to coupled, time-varying fan noise, ATNAC can establish an acoustic radiation model of the turbofan engine noise caused by turbulent flow compression/discharge even in realistic, unpredictable aeroacoustic environments. The nonlinear active control module, based on noise profiles from the acoustic radiation model, will rapidly eliminate engine noise by flexibly controlling multiple hybrid skin-like arrays of active and passive actuators. The ATNAC hybrid skin-like reactive actuator devices will be compact and power efficient. In Phase I, POC will optimize the system configuration and methodology, and will design algorithms and hardware specifications for ATNAC. POC will then demonstrated the feasibility of performing instantaneous, omnidirectional, adaptive time-varying modeling for active noise cancellation by means of hybrid reactive noise suppression actuators. ATNAC technology will have widespread applications in both the government and commercial sectors. It will be a valuable tool for controlling acoustic noise and vibration in a wide variety of platforms and structures. Potential users of this technology include the military, the aerospace industry, structural engineering firms for earthquake protection of buildings and other structures, and precision machinery firms.

Title:Acoustic noise reduction for large aircraft
Abstract:Noise reduction from large military aircraft is significant as airfields encroach on residential areas. Two methods of noise reduction are possible: active and passive. This proposal will outline a tunable, passive method that can stand alone or be used in conjunction with active methods to reduce aircraft engine noise. This proposal will attempt to apply passive methodologies to this noise problem that have been successfully demonstrated in an active DARPA funded Phase 2 effort in Acoustic Bandgap Devices and Materials. Acoustic Bandgap cowel-type enclosures, suitable for aircraft engine shapes and frequencies, have been modeled with predicted results of greater than 20 dB over a wide range of directional angle and frequency. These prototype devices, currently in testing, are surpassing predicted attenuation levels. These device configurations are frequency tunable with changes in geometry (static or dynamic)have substantial potential to passively reduce noise from from both military and commercial aircraft. These acoustic bandgap materials and devices are totally passive and can be tuned to attenuate certain ranges of frequencies. There is no power required and their are no moving parts. These design principles for which models have been devloped can be applied to aircraft engines and airframes in both commercial and military applications.

Title:Modular Composite Roll On/Roll Off Ship Ramp Structures
Abstract:In this Phase I proposal DDL OMNI Engineering proposes to demonstrate the feasibility of an innovative composite Roll-On/Roll-Off (RO/RO) ramp concept that enables in-stream transfer of cargo from logistic supply ships to floating causeway RO/RO discharge facility (RRDF) platforms during sea state 5 (SS5) seaway conditions. The concept is based on the development of modular composite RO/RO ship ramp structures that incorporate several unique design features enabling the structure to respond in an acceptable manner to dynamic seaway conditions. These design features are: (1) a lightweight, high-strength and modular composite structure based upon application of low cost "Cell Core" technology; (2) smart composite manufacturing processes to permit low cost and reliable manufacture of the composite structural elements; and (3) the integration of flexible structural joints with elastomeric bearings and/or flexures (leaf springs) into the ramp support structure to provide supplemental motion compensation and controlled flexibility. Work will include both static and dynamic analyses of the proposed concept to estimate the relative motions between ramp ends and accelerations imparted to vehicles traversing the ramp structure. The concept will be refined during Phase I by using design optimization procedures to conduct performance and cost trade-offs. The proposed concept offers a potential to manufacture affordable composite ramps with a 40-60 % weight reduction compared to conventional steel ramps. The modular fabrication approach provides tremendous flexibility during design and manufacture of composite ramp structures of various dimensions, weight requirements, and rated load capacities. The modular approach enables application across all logistic supply ship classes. Private-sector applications include commercial shipping, high-speed ferries, and automobile carriers.

Title:Advanced Composite RO/RO Ramps with Active Controls for Sea State 5
Abstract:Current Navy Roll-on/Roll-off ramps and RRDF platforms for in the stream cargo transfer are limited to operation in sea state 3. New concepts of Expeditionary Warfare require greater standoff distance, resulting in operational exposure to conditions up to sea state 5. Foster-Miller proposes a system study that incorporates our large composite bridging expertise with the RO/RO experience of MacGregor, Inc, the Class Standard supplier of ramps for the Navy. The composite material will be 25 percent lighter, more corrosion resistant, and have greater overall strength and flexibility. The Foster-Miller system will include active controls to isolate the ramps and cargo from the extreme wave motions and forces. Floating body relative motions will be developed using state of the art software. The key focal points of the program will be sea state 5 capability, weight savings, and operational efficiency. Foster-Miller will team with MacGregor Inc, and also Professor Paul D. Sclavounos, Director of the MIT Laboratory for Ship and Platform flows, a leading expert in relative motion studies. The program will develop concepts that will be risk reduced in Phase II with follow-on model basin testing and commercialization through MacGregor.(P-030205) The development of cargo transfer systems for conditions up to sea state 5 will be a useful technology to the Navy, in sync with the future long term goals of the Military Sealift Command (MSC), and upgrades to the LMSR fleet purchased under the Strategic Sealift Acquisition Program (SSAP). Lighter weight structures with the ability to handle the high relative motions imposed by sea state 5 will enable the greater stand-off distances anticipated by new concepts in Expeditionary Warfare. Many commercial sea cargo companies could benefit from advances in the technology proposed here. Large ocean going vessels could be reliably offloaded or re-stocked without needing to dock in a deep draw harbor, reducing reliance on ports with large vessel capability, and increasing global distribution capability.

Title:Low Cost, Impact Damage Resistant Pultruded Polyurethane Matrix Composite Ship Structure
Abstract:KCI will work with Bath Iron Works to design and produce low cost, highly damage resistant pultruded ship hull structure. While technology is generically applicable, the baseline implementation is the forward hull bottom of LCU 1646. This hull section, currently 1" steel plate, is subjected to severe impact and abrasion during beaching operations. Future Naval doctrine will require hulls to move at much higher speed, so weight reduction will become critical. KCI's proposed solution includes 1) use of >100% strain-to-failure Adiprene polyurethane as a matrix material, 2) use of a macro-composite design approach to achieve an otherwise unobtainable combination of structural stiffness and damage resistance. KCI has previously demonstrated the effectiveness of this material and configuration combination by pultruding damage-resistant steel-replacement CVN stanchions for the Navy and commercial customers, and 3) use of pultrusion processing to make extremely large panel sections at a cost that can be half that of the more widely used VARTM process. KCI has demonstrated this concept by pultruding panels up to 10-feet wide for applications such as a 6"-thick composite Navy pier deck. Phase I will include design, test sample fabrication and testing to validate mechanical, impact and fire properties of candidate designs. The proposed program will demonstrate a generic, cost effective process for making lightweight, highly damage resistant composite ship structures. While the baseline parts for this specific SBIR are relatively small, one attractive feature of the proposed pultrusion process is its ability, using the same approximately 3-foot long die, to make finished composite parts of any manageable length. Since material wetout, consolidation and cure occur in a single, continuous process with no touch labor, finished cost approaches raw material cost. Using KCI's 10-foot wide pultrusion machine, for example, throughput of composite ship structure at rates up to tens of thousands of pounds per hour is possible. This presents an attractive opportunity for making much larger composite ship structures for DDX and CV(x) at a cost that is not significantly higher than steel, and far less than similar VARTM components.

Title:Enabling Hull Structural Innovations for High-Speed Lighters
Abstract:Triton Systems Inc. proposes a novel approach for the development of lightweight, low cost, highly impact resistant and environmental friendly composite hull structural panels for next generation high speed lighters. The approach is based upon engineering of advanced thermoplastic composite (TPC) materials for the transition of metallic structures to cost-effective, structurally-efficient polymer matrix composites. Triton proposes to use its polymer additive, for flame retardancy in the thermoplastic resin system and good impact properties. Triton will re-engineer the current 1" thick mild steel structure and explore a range of composite structural designs that will provide a great level of durability/impact resistance and increased corrosion resistance than the current steel structures using low cost fiber, matrix and core materials and an affordable manufacturing method. Once the material and design is finalized, the selected panels will be fabricated using Triton's innovative continuous thermoforming process (CTP). Composite technologies, resulting from this effort, that provide a cost effective means of delivering a higher strength-to-weight ratio would find myriad uses in both the military and commercial sector. These technologies would be useful in regions with underdeveloped ports where high-speed transport and beaching (or other impact loading) are both desired. In addition, this technology would be applicable to any situation where high speed shuttles and at-sea interoperability are desired like offshore supply vessels and cruise ship shore launches. Other possible applications include substitution of structural and non-structural metal parts in the military and commercial aerospace, marine, construction and automotive sectors where a need exists to reduce the weight and/or signature of an item, eliminate corrosion problems, or improve fuel efficiency.

Title:Affordable Parts Library Catalog System
Abstract:The objective of this proposal is to build a practical, cost-effective and highly flexible parts library catalog system for commercial shipyards. The proposed catalog systems will complement typical medium to small shipyard IT infrastructures and will enable these shipyards to implement and benefit from improved e-commerce and supply chain concepts. Parts Library Catalog Systems are a means to provide parts information for shipyard design, procurement, and planning processes. Parts data are only entered once, then re-used many times in different areas of the shipyard's business. The catalog system can help to reduce the labor content and overall cycle time for all parts related business processes. This proposal will build on Atlantec's Topgallant suite of interoperability products and the architecture and data models developed in the NSRP ISE projects. It will focus on the requirements of small to medium sized shipyards, though. During Phase I of this project Atlantec Enterprise Solutions, Inc. plans to define parts catalog system requirements, to develop product specifications and to prototype an early implementation of the parts catalog system in cooperation with its partners Bender Shipbuilding & Repair Co., Inc.,Kvaerner Philadelphia Shipyard, Inc., Liberty Consulting, Knowledge Based Systems, Inc.. The proposed development will provide an affordable and practical parts catalog system for small to medium U.S. shipyards. This new parts catalog system will enable shipyards to implement and benefit from new e-commerce and supply chain concepts. It will support a seamless flow of information for the complete supply chain, and will streamline and simplify parts related business communication and processes. The parts catalog system can help to reduce the labor content and overall cycle time for parts related business processes. Parts data is entered once then re-used many times in different areas of the shipyard's business. The time required to define and select supplier parts for a specific design can be significantly reduced. Also, the procurement process, i.e. the request for quotation, offer evaluation and the ordering will benefit from a common parts information base at a shipyard. Design changes and rework induced by inconsistent parts information can be eliminated. Also, part equivalency checking can be a big cost saver for the shipyards.

Title:Guided Metal Cutting
Abstract:The NSRP Advanced Shipbuilding Enterprise (ASE) Strategic Investment Plan identifies the major initiatives that are required to promote commercial competitiveness and thereby reduce the cost of military ships. An important research area that is identified in the Strategic Investment Plan is improvement of manufacturing technologies. One of the most basic manufacturing processes is the cutting of metal, which is one of the first steps in transforming a piece of metal into a structure. Current metal cutting imposes the requirement that rough cut edges and dross be machined down to an acceptably smooth surface prior to welding, which significantly adds to the production costs. To reduce or eliminate post-machining, NSRP ASE has been promoting several laser-based cutting strategies that produce cuts that do not require post-machining. Despite this promise, few shipyards in the United States have adopted these practices. High cost and safety issues have prevented at least some shipyards from pursuing this technology. Creare, with the support of two major U.S. shipyards, is proposing a retrofit to standard cutting torches that promises to offer high quality cuts, akin to laser produced cuts, at a fraction of laser cutting capital and operational costs. Shipyards will be able to leverage their existing cutting infrastructure using Creare's innovative technology. As such, high quality cuts produced at low cost will lead to significant production savings for U.S. shipyards. Creare's innovation will also find application in any metal forming industry such as automotive, aerospace, and construction.

Title:Agile, wireless enabled Workflows for Ship Manufacture and repair (AWSM)
Abstract:We propose to develop a new paradigm for ship manufacture that is based on reengineering the processes to take advantage of pervasive computing, ubiquitous pull and push of information and optimal delivery of information to every user, work crew, or process. The focus of the effort is not just to wireless enable manufacturing processes, but to completely re-engineer the processes in which the workload is optimized to take advantage of the flexibility and connectivity of PDA, Tablet PC, and wireless technology. Because of longer horizons for information collection currently there is a perpetual gap between the status of the manufacture facilities and the state represented in information systems. Operators often view plans as some idealized states, which are difficult if not impossible to achieve in reality. The proposed "Agile, wireless enabled Workflows for Ship Manufacturing and repair" (AWSM) addresses this problem by taking advantage of pervasive computing, data collection and display technologies. AWSM will focus on material planning, procurement, kitting, production planning, scheduling, and manufacture. AWSM will build upon and extend the scheduling (WorkShip) and material planning and procurement (MIDAPS) technologies. AWSM will be developed based on modular and customizable concepts so that it can be transitioned to multiple shipyards. The proposed effort will revolutionize the manufacturing and support processes in shipbuilding and help transition to an agile, and lean environment. It will result in orders of magnitude efficiency improvements and bottom-line cost reductions. This is achieved by re-engineering the processes to exploit the wireless connectivity and optimal delivery of information to every user, work crew, or process. The proposed effort will also result in better quality of data in information systems by virtue of making information collection and distribution an integral part of shipyard processes. Direct beneficiaries of the proposed technology will be U.S. shipbuilding and ship repair. The proposed solution will be implemented at Bender. The proposed technology will benefit the U.S. manufacturing and service industry in the long run.

Title:Portable High-Energy Semicoductor Diode Lasers for Interior Ship Coatings Removal
Abstract:The objective of this SBIR is to investigate and develop a portable laser decoating system that has the capability to remove coatings used in the construction of Navy ships. Corrosion control is a major issue in new ship construction as well as in ship repair where significant amount of time is spent in applying and removing paint from the interior of ships for spot decoating. This includes the regular removal of a significant amount of preconstruction primer, and interior epoxy coatings. The present methods of abrasive blasting generates additional waste but more significant is that entire spaces must be masked off for blasting not allowing other trades to operate in or around the space until the operation is completed. A portable, high power, diode laser would be capable of allowing the surface finishing trades to spend minimal time in a space spot decoating, allowing the other trades to start sooner, thus avoiding costly delays in construction. Diode laser decoating has been proven to efficiently remove new coatings such as powder coats being used in shipbuilding, as well as being able to efficiently remove coatings from PCMS, composite, fiberglass, and other "soft" substrates controlled and providing repeatable first time quality. The steps to successful commercialization of this technology are to evaluate and demonstrate the successful application of the technology to a specific area, i.e. shipbuilding/repair, perform the qualification testing, obtain approval, publish and market the results, design and build, and then produce systems. This Phase I project will entail the first steps required for commercial approval, developing a preliminary design and cost analysis, which are critical to implementing the technology. Once the initial steps are performed and passed, Phase II will entail completing the approval process testing, obtaining the formal OEM approvals, establishing environmental technology requirements with the Navy, finalizing the system design, and then producing the prototype and production units. A high power portable laser decoating system would have great demand in the industrial sector, both commercial and government. Being high power, above 1 kilowatt, makes the stripping rates competitive with abrasive blasting, and thus opens the market to the steel structure paint removal industry as well as commercial paint removal, especially lead paint, and as well as shipyards throughout the world. A system like this would have the inherent advantage of being environmentally friendly, having only to deal with a minimal amount of waste, thus avoiding a significant cost to shipbuilding. This technology is also capable of stripping advanced materials such as composites, and can be used on future ships being proposed that will employ more composite technology in construction.

Title:Lightweight, Low Cost, High Quality and User Friendly Fire Zone Bulkhead and Overhead Insulation
Abstract:Containment of the heat in any fire is crucial to reduce the potential for severe damage and loss of life. This is particularly true for any ship at sea. "Fire Zone" bulkheads and overheads, as defined by regulatory requirements, provide this containment. The Navy requirement MIL-PRF-XXX381 corresponds to the commercial H-30 rating, providing 30-minute protection against hydrocarbon fire spread beyond the boundary. NoFire Technologies is developing an H-30 rated insulation that is approximately 30% thinner and 30% lighter than the currently used insulation. It is easier to install and costs less. NoFire will complete the development of H-30 insulation and perform tests to pass MIL-PRF-XXX381 requirements. The shipbuilding industry, both military and commercial will have a product greatly superior to current insulation used to provide H-30 fire zone protection on board ship. Northrop Grumman Ship Systems has expressed interest in this NoFire product and is committed to assisting in this Phase I qualification effort. The potential benefits of this work is a fire zone bulkhead that complies with H-30 (for military applications) or A-60 (for civilian applications) that is lighter, less expensive, easier to handle, and has reduced airborne particulates as compared to current insulation products

Title:A Low Cost, Touchless Tracking Alternative for Welding Ship Panel Stiffeners
Abstract:Ship structures are fabricated from steel plates with thousands of reinforcing stiffeners welded to them. Each stiffener requires a quality weld. Existing welding machinery typically use a mechanical or electronic torch tracking system. Quality welds can be obtained with both systems, but each has drawbacks. The mechanical guidance systems are not capable of tracking all weld joints. Electronic systems command a sizable investment. Electronic guidance system prices can be up to $50,000 per torch. A typical automated stiffener welding machine can contain as many as 8 weld torches, along with 8 guidance systems. Phase 1 of our project is to develop a low cost tracking system with superior tracking and minimal maintenance. The torch tracking will be a "no touch" system that does not require contact with the weld joint and will have no contact parts to wear out or be damaged. Our objective is to show the feasibility of an operational system with high quality characteristics. Existing welding machinery can be retrofitted or upgraded to use this system. Our goal is to provide a touchless tracking system at a significantly lower cost than competitive systems. A Phase 2 prototype will confirm that this price is realistic. Affordable torch tracking systems will increase weld quality while reducing ship construction costs. This system will have widespread use in Naval ship construction and related industries.

Title:FLASH - Fiber beam delivery for Laser Applications in the SHipbuilding industry
Abstract:Current laser metal processing applications in the shipbuilding industry are limited by several factors. Commercial Nd:YAG systems only deliver power up to about 4 kW, and work at a wavelength that requires class A eye protection enclosures. These conditions severely limit Nd:YAG laser use in shipbuilding, since it deals with thicker steel and production operations that are performed on large components that are impractical to fully enclose. CO2 lasers operate at an eye-safe wavelength. However, the absence of a commercial fiber at this wavelength, along with some other factors, has limited CO2 lasers to hard optic systems. This requirement has resulted in CO2 lasers being limited to large gantry style systems with a complex series of bend mirrors. Recent developments in optics have produced new concepts that will allow transmission of relatively high power CO2 laser beams through flexible fibers. High-power beam delivery has been shown to be feasible theoretically. Hollow, flexible photonic bandgap fibers (OmniGuide PBFs) for guiding low power CO2 beams have recently been produced and tested (Nature, Vol. 420, p. 650, 2002). We propose developing OmniGuide PBF to efficiently guide multi-kW CO2 laser beams for power delivery in laser processing applications for shipbuilding. Our solution will reduce cost, simplify maintenance and increase the flexibility of laser systems. The ability to deliver CO2 laser power through a fiber greatly expands the possibilities for laser applications in shipbuilding and other applications. The fiber delivery mechanism will allow existing NC or semi-automatic cutting and welding systems to be easily retrofit with laser capabilities. In metal welding applications, the fiber will facilitate the use of CO2 lasers rather than more expensive Nd:YAG lasers. Both the operating and capital costs of CO2 lasers are 50% below the costs for Nd:YAG lasers at any given output power; furthermore, the eye-safe CO2 laser wavelength reduces the cost for full safety enclosure of Nd:YAG laser stations. The only reason for the success of Nd:YAG lasers in the marketplace is the availability of fiber beam delivery. CO2 lasers with fiber beam delivery should thus be the technology of choice for metal welding, assuming fiber costs are reasonably close to those for Nd:YAG fibers. In sheet metal cutting applications, a fiber will reduce the cost of the CO2 laser beam delivery system and therefore allow simplified and cheaper system designs. The savings should be up to 25% on a typical system.

Title:Machinery Health Monitoring for Shipyard Productivity
Abstract:The team of RLW Inc., Applied Research Lab of Penn State University, and NASSCO (National Steel and Shipbuilding Company) will build and demonstrate a wireless machinery health monitoring system for large rail-mounted shipyard cranes. The demonstration will be designed to show that affordable machinery health monitoring technology can reduce shipbuilding costs by improving the reliability of shipyard cranes while reducing the cost of their maintenance. The system will include algorithms; transducers; and multi-channel, wireless, health monitoring devices as well as the local area network and hand-held devices needed for a complete, functioning system. The system will conform to the Open System Architecture (OSA) protocols. Monitored components will include wheel bearings and motors, a hoist motor, and a diesel generator. The proposed Phase I option will transition the lessons learned to a T-AKE ship crane demo of shipboard machinery health monitoring. The shipyards that build the Navy's ships as well as the Navy-owned yards that repair them can improve the reliability for their production equipment while reducing the cost of maintenance by increasing the use of machinery health monitoring systems. The large shipyard cranes selected for this project offer an excellent target for these technologies due to the very high cost and ripple-effect of a crane component failure. Because of the crane's mobility, the wireless approach is particularly applicable. The technology to be developed and demonstrated will transition readily to shipboard applications including the cranes on the new T-AKE ships. Many paths for commercialization are available for project results: 1) The private yards such as NASSCO; 2) Navy shipyards; 3) Navy ships, including T-AKE ships, other new ships, and the entire legacy fleet; 4) Private ships and oil rigs.

Title:Technology for Shipbuilding Affordability
Abstract:Vexcel Corporation in conjunction with Todd Pacific Shipyard Corporation, propose to develop a 3D measurement system similar in concept to the proven FotoGTM technology but based on a single digital video input stream rather than a set of varying viewpoint digital still images. . Decrease field time Vexcel proposes incorporating a simple accurate control point identification methodology through the use of automatically recognized photogrammetric targets located on reference length elements. These reference length elements would be placed in the scene at the beginning and end of the path captured by the video camera. . Decrease time to CAD model A video stream consists of a sequence of images taken at 1/30th of a second intervals so that there is very significant image overlap between any pair of frames. Given that the images will have a great deal of image overlap, computer vision algorithms (such as those currently imbedded within FotoG), are able to identify common points between two sequential frames and calculate the relative change in camera position. It is these calculated camera positions combined with the calibration of the camera lens/CCD that is used to create 3D measurements. Vexcel Corporation is are particularly interested in this SBIR proposal because of the great commercial potential for the proposed system. Many industries have a growing need for cost effective three-dimensional (3D) models of real world sites or objects, either for engineering applications or for use in virtual reality simulators. Additionally, the significant reduction in on-site labor required to acquire field measurements with this proposed system would dramatically reduce the risk to employees in environmentally hazardous and hostile areas ? a significant driving force to purchase this new technology in many commercial and military applications. Vexcel has been a leading provider of digital photogrammetric modeling systems over the past decade. We have commercialized DARPA, NASA, and DOD SBIR research into a robust photogrammetric application (FotoGTM) that is in use worldwide. Application areas include the aerospace, petrochemical, automotive, nuclear, architectural, and entertainment industries. o NASA uses FotoGTM on the International Space Station and the Space Shuttles, o Ford uses it for 3D modeling for robot simulation, o US, British, and Australian Air Forces use it for modeling aircraft and weapon systems, o Framatome uses it to model entire nuclear power facilities, o Procter & Gamble uses it for modeling entire process facilities Vexcel has extensive experience in the development and commercialization of complex systems for terrestrial, aerial, and space borne photogrammetric and radar applications. Examples include our robust, widely used close-range photogrammetric system (FotoGTM), aerial photogrammetry based 3D city models and line-of-site software system (VexLink), as well as Synthetic Aperture Radar (SAR) processors and ground stations.

Title:Intelligent Shipyard Welding Procedure System
Abstract:Welding is a major shipbuilding activity requiring a large amount of labor-intensive documentation. Not only is the time required for preparing, documenting and validating welding procedures costly, but in many instances improper documentation results in significant delays in the production schedule. Shipbuilders recognize that productivity could be enhanced through computerization of welding procedure information, as demonstrated by letters received from five major U.S. Shipyards which support the proposed effort. WeldWare proposes to develop an Intelligent Shipyard Welding Procedure (ISWP) system to reduce both costs and construction delays which result from improper welding procedure documentation submitted by suppliers. The proposed system meets the needs of the "Technology for Shipbuilding Affordability" topic by: ˙Providing a means for electronic transfer of procedure data within shipyards and throughout the supply chain, ˙Mistake-proofing the welding procedure generation and submittal process, and ˙Reducing non-value added activities by automating the labor-intensive procedure checking process. The Phase 1 work will involve developing a preliminary system design, a demonstration of the technical feasibility of the design, and an estimate of the financial return-on-investment from deploying the system. In Phase 2 a pilot system will be constructed and deployed at Newport News for Aircraft Carrier procedure control. A user-friendly Intelligent Shipyard Welding Procedure (ISWP) system would have an immediate impact to reduce procurement costs throughout the shipyard supply chain. An ISWP system would eliminate significant labor expenditures and production delays which result from the inefficiencies of the current paper-based welding procedure control system. The ISWP would enable shipyards and their suppliers to accurately and quickly prepare procedure qualification records and allow the procedure users (i.e., planners, engineers, production trades) to easily identify the proper procedure for a given application. The following additional benefits would be realized by developing and deploying an ISWP system: ˙Reduced supplier cost by providing an efficient means for procedure development, revision, searching, and submittal, ˙Fewer delays in suppliers obtaining shipyard approval for welding procedures, ˙Fewer shipyard production schedule disruptions due to rejection of supplier procedures, ˙Better accuracy in preparing welding procedures, ˙Automated review of vendor procedures will reduce the shipyard labor cost associated with the current review process, ˙Improved consistency in procedure format between shipbuilders will support the NSRP data-sharing initiatives, ˙Automatic searching for the proper procedure for an application will reduce the risk of selecting the wrong procedure and will provide greater degree of confidence in satisfying specification requirements, ˙Reduce or eliminate need for paper copies of procedures.

Title:High Performance Quantum Cascade Lasers for Free Space Communications
Abstract:In this Phase I effort, Maxion will assess the feasibility of developing a high-operating-temperature, high average power, quantum cascade laser emitting in the 9-10 micron wavelength region for application in free space communications. The effort will focus on laser design and fabrication methodologies that lead to low threshold current density and effective heat removal from the device's active region, enabling the necessary performance at high operating temperatures. Devices will be fabricated in an epi-side-up geometry in a manner that incorporates an effective lateral heat conduction path, promoting two dimensional heat conduction. Additionally, active region design will incorporate features that minimize transparency current and reduce threshold currents. The demonstrated quantum cascade lasers will be thoroughly tested and their performance characteristics will be compared to those of the free space optical communication application. The performance requirements of the free space application will be determined using reasonable optical link parameters and power level budgets. Necessary improvements to device performance characteristics will be identified and addressed. If successful, this project will lead to quantum cascade lasers that operate in the 9-10 micron region at high temperatures under cw conditions and with high average powers at room temperature. The device design and fabrication principles that enable this performance level can then be used to extend the wavelength range where high performance is available. The resulting quantum cascade lasers can then be used in a variety of application areas in addition to free space communications. Applications areas of importance include the trace level sensing of a wide variety of chemicals in diverse fields including pollution monitoring, industrial process controls, medical diagnostics and therapeutics, and explosives detection.

Title:Development of Quantum Cascade Laser Heterostructures for Mid-Infrared (4-5 Micron) Atmospheric Transmission
Abstract:This proposal will demonstrate the feasibility and design of quantum cascade lasers for ambient temperature free-space communication in the mid-infrared (4-5 microns). An ideal system would include an uncooled, compact, and durable source of laser radiation in this wavelength range. Conventional semiconductor laser technology has so far been unable to produce high power lasers in this wavelength range without optical pumping and/or cryogenic cooling. The quantum cascade laser, while demonstrating excellent performance for lambda >5 microns, is relatively undeveloped in the 4-5 micron wavelength range, which is suitable for free space communication. This is due, in part, to the necessary use of highly mismatched materials in a strain-balanced configuration. In Phase I, determination of the output power and duty cycle required for free-space communication will be investigated. A systematic approach to optimizing the high duty cycle performance of a highly strain-compensated quantum cascade laser will then be undertaken, focusing on material growth, doping distribution, material characterization, and room temperature, high-duty cycle, testing data. Current free space optical systems are hindered by scattering elements (such as fog or smoke) and scintillation effects. Both act to shorten or completely sever a free space optical link. As predicted by scattering and scintillation theory, a mid-infrared laser source should have superior transmission through a non-ideal atmosphere as compared to a commercially available near-infrared source. This significant performance boost is especially noticeable in a somewhat dense smoke or fog condition, which is one of many likely atmospheric conditions on a battlefield. As it is most important to maintain contact in precisely these conditions, the development of a longer wavelength optical link can potentially save many lives due to uninterrupted intelligence. A secondary benefit of this work is the eventual development of a high power laser module for potential use in other areas, such as remote chemical sensing or infrared countermeasures, both of which are extremely important in the commercial and/or military arena.

Title:Novel miniature RF Filter fabricated on ferroelectric substrate
Abstract:Recently, expanding wireless, cellular and other mobile communication systems have presented new challenges to design and produce high quality miniature filters with low cost. Currently the RF filter is by far the largest element in some subsystems of wireless communications. Dymas Research proposes a novel RF filter fabricated on dielectric substrate covered by low loss thick BST film on its both sides. The dielectric constant of BST film are very high, therefore we can design the RF filter in a smaller size. Dymas Research proposes to fabricate novel miniature RF filters on high quality low-loss thick Ba0.5Sr0.5TiO3(BST) film on a LaAlO3 substrate. The configuration of planar circuit filter will be used to design the proposed filter. Planar circuit filter have the advantages of small size, lightweight, low cost, and compatible to monolithic substrate technology. Ferroelectric /dielectric/ferroelectric structure substrate also provide electric tunability for adaptive microwave devices. This tunable microwave device has the advantage of achieving frequency or phase tunability. Success in the Phase I effort will lead to the commercial fabrication of new generation of tunable miniature RF filters. This advanced device will offer the potential for significant performance improvements in military and commercial applications. The development of a materials technology that reduces effective loss tangent is expected to benefit all electrically tunable microwave devices that could utilize low insertion loss or high quality factor.

Title:Single Channel Ground Moving Target Indication (GMTI)
Abstract:CAE Soft Corporation proposes to demonstrate the feasibility of an innovative approach to simultaneous detect, track and geo-locate both moving and stationary targets in a manner that can be readily implemented in the single channel APS-137 radar.The Single Channel Moving Target Indication (SC-MTI) mode when used simultaneous with the SAR mode will provide the APS-137 the ability to continuously and simultaneously detect, maintain track, and geo-locate ground moving as well as stationary targets though all phases of their movement history. This ability to continuously track Ground Moving Targets (GMTs) that repeatedly move, stop, and move in a dense moving object environment would significantly improve the APS-137's capability in the critical areas of dominance in the military theater and tracking and targeting of time critical targets. The anticipated benefits are the development of a specific Single Channel GMTI mode but the methodology of the development will extend to both military and commercial applications. Potential civilian applications include airport surveillance radars and multi-function radars for commercial aviation that simultaneously perform wind shear detection and landing assistance displays as well as remote sensing for earth resources. The most applicable for this technique if for earth resources remote sensing function which requires the removal of stationary and moving man-made objects from the data so that the background soils and crops can be examined.

Title:Single Channel Ground Moving Target Indication (GMTI)
Abstract:DSR proposes to develop and evaluate radar waveform and processing techniques that can provide integrated Synthetic Aperture Radar/Ground Moving Target Indication (SAR/GMTI) air-to-ground search and track functions for application to single-channel, single aperture radar sensors. Integral to the development objective is the continued dominance during both air-to-air and air-to-ground missions carried out by manned fighter/attack and unmanned air vehicles (UAVs) for which available radar aperture space is limited. The proposed approach develops single-channel multiple-frequency concepts that will provide GMTI performance consistent with the capabilities of multiple-aperture/multiple phase center systems. A single-channel SAR/GMTI capability is envisioned for single-dwell detection of ground targets at medium and long ranges. Scan-to-scan track detection in a Doppler Beam Sharpening (DBS) mode is envisioned for short range GMTI. Coherent and non-coherent sub-beam processing and range/azimuth track analysis will be investigated for moving-target detection and location. Sub-beam correlation methods will be investigated to improve signal-to-clutter discrimination for slow-target detection. System analysis and modeling will evaluate GMTI applications for radar systems that include mechanically or electronically scanned antennas. Resource-allocation for simultaneous air-to-ground and air-to-air functions will be demonstrated using a DSR developed radar simulation and scenario model. Anticipated Benefits/Potential Commercial Applications of the Research or Development:This work could be applied to applications suitable for other military surveillance and identification requirements along with government, law enforcement and commercial recognition/identification needs such as airline surveillance and ground traffic control, border and coastal waters surveillance, drug interdiction and commercial vehicle location and tracking, geological and forestation surveys and mapping.

Title:Sensor Independent EW Functionality Interface
Abstract:The threats countered by Electronic Warfare (EW) systems are continually evolving, necessitating that EW sensor subsystems evolve to keep pace with the threats. To create the best possible EW system, the EW system needs to be designed with sensor subsystem flexibility in mind. An EW system designed with sensor subsystem flexibility can adapt to existing and new sensor subsystems, creating a combined situational awareness picture using information from all its sensor subsystems. In additional to sensor subsystems under development, several sensor subsystems are currently available for incorporation into surface ship EW systems. The Naval Research Laboratory (NRL) has developed numerous sensor subsystems to add new EW capabilities, including new High Gain High Sensitivity (HGHS) functionality, Specific Emitter Identification (SEI) functionality, and Advanced Multi-Function Radio Frequency (AMRF) common phased array sensor functionality. EW systems should also be able to take advantage of sensor subsystems already fielded, like the existing SLQ-32 Electronic Support Enhancements (ESE) sensor subsystem, the Light-Airborne Multipurpose System (LAMPS) helicopter sensor subsystem, and other commercially available sensor subsystems. To this end, PMS473 commissioned a study, "Block 2 ES Needs and Options Assessment" , to study existing sensor subsystems architectures and assess their performance advantages and disadvantages. Designing a sensor independent EW subsystem will be applicable to commercial opportunities involving sensor subsystems. These opportunities include security and homeland defense applications, and geophysical exploration and seismic applications as well.

Title:Laser Beamrider Optical Countermeasures
Abstract:Today's military aircraft require protection against a new generation of laser beamrider (LBR) threats that are more capable and difficult to defeat. In many cases, high levels of disruptive Optical Countermeasures (OCM) jamming energy must be directed at the LBR operator to temporarily dazzle his optical tracking system (human eye or EO camera/video) to prevent him from maintaining a steady lock and track on the target aircraft. We are proposing to develop a unique and innovative concept to meet these protection needs for DOD military aircraft from the LBR threat. Our LBR-OCM concept concentrates on using low cost high brightness expendables to disrupt or dazzle the LBR tracker (human or electro-optical). Our LBR-OCM expendable will be eye safe in its intended use and deployment. The primary benefit of this work is to provide a low cost, robust countermeasure against laser beamrider threats to aircraft. Commercialization of the expendable technology will involve product development, marketing and distribution of the system to three specific markets: military platform defense, antiterrorism and border surveillance, and civil defense. A primary candidate for commercialization of our LBR-OCM technology is for police SWAT and riot control teams to effectively diffuse unruly mobs and accomplish surprise interdictions with minimal threats.

Title:Laser Beamrider Optical Countermeasures
Abstract:Laser Beamrider weapons are extremely difficult to countermeasure since the missile data acquisition sensors face away from the attacked target, making it impossible to disrupt from the target angle. Weapon guidance and discrimination is the guiding human, usually with gain optics. To effectively countermeasure the weapon system, the human must be fooled, momentarily distracted, or momentarily blinded. If a momentary blinding approach is taken, care must be taken not to blind the pilot or a wingman of an adjacent friendly aircraft, thus the blinding energy must be directional. The countermeasure must also be difficult to countercountermeasure. SPEC's countermeasure approach allows a short duration, directed beam of broadband light to be fired at the weapon-guiding human. The beam is directed to the coordinates obtained from the Laser Warning Receiver. The minimum radiation intensity directed at the observer is approximately the same as a camera photoflash at 1-2' range. Even in ambient daylight, this creates a disrupted vision for 3-5 seconds. The broadband character of the light makes bandpass filters ineffective as a CCM tactic. The key breakthrough features of the device are ultra capacitor storage device, short arc high-pressure Xenon lamp, and flush mount, millisecond response time, directional beam pointer. Beyond the benefits of a successful countermeasure unit for laser beam rider weapons, the technology proposed can also be implemented where ultra high energy, quick discharge power storage units are needed, and where ultra high flash light outputs are needed. For crowd control and other police work, a hand held unit could temporarily blind, daze and confuse the targeted individuals. It could also be used as a reusable stun grenade or flash unit to neutralize/disrupt the targeting ability of a sniper/assassin, provision of cover for personnel movement during barricaded suspect situations, distraction of defender during drug warrant service, and disruption of criminal activity during robberies, are but a few possible instances of civilian law enforcement use. The energy storage device could pave the way for high-energy lasers, N-ray tubes or superconductor magnet charging. For example, 10Kjoules in a fast discharge, packaged in a less than 3-pound unit, opens uses deemed impractical in the past.

Title:Multi-National Cultural Difference Modeling
Abstract:As demonstrated with recent engagements, US forces will not go into combat alone. Multinational coalition forces will be the norm and our forces must flexibly adapt to the command and control (C2) environment with the newly formed team. Whether a neighbor or long time ally with similar but distinctly separate C2 styles or a geographically separated ally with little common C2 techniques, the end product must be the same; a seamless C2 system capable of allowing the decision maker to correctly assess the situation via sensors and to relay his intentions to the shooter in a timely and correct fashion. The presence of multinational cultural differences presents barriers to successful coalition command and control. These cultural differences must be understood, modeled, and simulated to provide an effective decision support system that can be utilized in a multinational coalition environment. 21st Century Systems, Inc teaming with the University of Hawai`i are proposing to extend the realtime tactical decision support capability inherent in the AEDGETM family of products by including modeling and simulation of cultural differences. Once implemented, the Multinational Cultural Differences Modeling could easily assist Operational, Theater or Tactical decision making in a number of environments being supported by coalition forces. The military applicability for the Multinational Cultural Difference Modeling is likely to be wide and far reaching. Operating in a multinational coalition environment will be the norm not the exception. Specifically, the benefit would be derived from knowing the culturally-based actions and reactions of coalition and enemy forces during one-on-one or many-on-many engagements. The need for Multinational Cultural Difference Modeling in the commercial global economy is dramatic. The capability to provide decision support and modeling for either the multinational economic, financial, or business markets would prove invaluable. This capability is would be the discriminator that would enable the financial or business success of entities that employ its cultural difference modeling.

Title:Modeling and Simulation of Cultural Differences in Human Decision-Making
Abstract:The main objective of Phase I is to produce specifications for a system with the capability of simulating individual and group decision making in contexts that are (a) collaborative, (b) multi-cultural, (c) uncertain, and (d) time stressed. The main technical goals are testing the feasibility of generalizing a method for eliciting and representing knowledge to the representation of transaction mental models and interaction strategies in a cross-cultural context, to extend and generalize algorithms for strategy selection to the selection of interactive strategies, and to model the results in a rapid, parallel computational environment. In Phase I, we will lay the groundwork for the construction and validation of a prototype system in Phase II. TBD

Title:Modeling and Simulation of Cultural Differences in Human Decision-Making
Abstract:While much research has been completed on the different elements of human decision-making, Pacific Science and Engineering is in the unique position to develop a model that incorporates variables from three components: culture, organization, and individual cognitive processes. The model will create a decision space where the three components interact. The decision space will include the decision process, with its required nodes and decision-maker roles. Each decision node will be populated with a decision-maker filling a particular role. Each decision maker will have decision heuristics and information processing patterns, based on prior experience and training. Cultural background, organizational culture, and external stresses and time pressures will be combined in the decision space to influence performance outcomes. Thus, the model will represent the interaction of variables from the three component models and will allow their effects to be anticipated. The Phase I technical objective is to develop a model that will identify how variables from the background culture, organizational process, and individual experience component models impact the decision-making process. This will allow the evaluation of alternative task assignments and operating conditions in order to reach the most effective blend. Ultimately, this model will allow military planners to forecast decisions and task outcomes of multi-national coalitions. The output of this research is a system that can be used to evaluate the performance of a decision-maker or a decision process under multiple cultural, organizational, and personal biases. Such a system has significant potential commercial value in both the DoD and private sector. In the DoD, for example, standard organizational structures exist for coalition operations, both for U.S.-led operations and for partner-led operations. During the planning cycle for the coalition, a structure is adopted and the different coalition partner decision-makers are fit into that structure. This system would allow an evaluation of the coalition partner decision-makers during the planning cycle and allow modification to an existing structure or to design a new structure that maximized the decision process outcomes, based on the cultural and individual biases of the coalition partners. The simulations can be used iteratively until the desired combination of decision structure and decision process is achieved. A precursor tool, developed by PSE under the DSSCO program, is already in regular use at PACOM and has received enthusiastic support from an influential multinational coalition working group (MPAT). Thus, an existing military ?customer base? already exists for this model. In the private sector, multinational organizations have long struggled with the ability to understand the decision-making styles of various national employees. Indeed, Hofstede?s original study was conducted by IBM to understand why motivators for their U.S. employees did not seem to work overseas. This system could be used by international organizations to mitigate the factors that cause problems between multi-national decision-makers. For example, if a multi-national manager wanted to proactively lessen deleterious effects on a decision process of a specific decision-maker who is prone to hyper-vigilance, the system would evaluate how to provide information to that decision-maker so that hyper-vigilance is avoided or its effect on the overall decision processes minimized. Even within a national organization, certain decision-makers may be identified as deadlocks in a decision or negotiation process. The system could be used, for example, to accelerate the process by providing feedback in order to reduce uncertainty associated with expected outcomes, reducing the number of options considered provided the options are similar to prior successful choices, and by providing options that are consistent with known expectations. In summary, this system, which provides general models of decision-making structures and processes, can help both national and international teams whether military, government, business, or even research, work together better. The commercialization strategy for this model is flexible due to the system architecture proposed by PSE. The knowledge bases and model could be fully incorporated into a large-scale system, such as GCCS-M or GENOA. It could also easily be distributed as a stand-alone software product, as PSE has been doing with its DSSCO tool. The most promising commercialization strategy for this system, however, appears to be via a web-based application. Users could purchase a subscription to access the system, which PSE could continue to update, maintain, and expand.

Abstract:Cermet, in collaboration with the Palo Alto Research Center, will fabricate and test a ZnO based semiconductor laser diode. Using Cermet's in house grown ZnO single crystal wafers, homoepitaxial films and epiwafers will be grown and characterized. A laser diode will be designed with a prototype fabricated at the end of Phase II. The applications for a room temperature, ZnO p-n junctions, LEDs and laser diodes are vast. A transparent p-type conductor would be available to increase the efficiency of established emitter and detector applications, including light emitting diodes, laser diodes, sensors / photodetectors, and photovoltaics. Additionally, a new family of transparent ZnO-based devices could be developed, including efficient UV/blue light emitting diodes, sensors / photodetectors, and laser diodes.

Title:Zinc Oxide Based Photonics Devices
Abstract:Recent experimental data indicate ZnO-based photonics devices such as light emitting diodes (LEDs) and laser diodes (LDs) that use arsenic doped p-type ZnO would have technical and operational advantages to those based on GaN. Principal advantages include ease of film growth at lower cost, larger exciton binding energy to give higher brightness in emisson and sensitivity in detection, the availability of single crystal ZnO substrates to reduce defect densities, and existence of wet chemical etching processes for use in the fabrication process. A shallow acceptor level increases the hole carrier activation ratio. Room temperature device operation should show higher efficiency, higher powers, and longer lifetimes. In Phase I, ZnO multilayer PN and PIN structure devices for UV light emitting and receiving applications will be fabricated using a new film growth technique that provides high quality films. Film materials will be characterized. Devices will be demonstrated and tested, and an optimization analysis will be made for output power performance, lifetime, gain-bandwidth product, excess noise and stability. Using these simple structures, feasibility for construction of multiquantum well structured devices will be made. Fabrication of ZnO quantum-well photonic devices will be undertaken in Phase II efforts. Device applications include opto-electrical communication from ship-to-ship, ship-to-submarine, or soldier-to-soldier; optical sensors such as UV detectors for missile plumes; civilian applications such as full-colored displays, DVDs, and high-power, high-efficiency white lighting; NASA space applications requiring lightweight, compact devices strongly resistive to high-energy radiation; and global air-pollution monitoring by UV, or cosmic radiation detection.

Title:Tools for Simulating Terrain Data
Abstract:Tactical decision aids provide commanders with the tools necessary to successfully operate in an environment flooded with massive amounts of data obtained from multiple sources. An important input to many decision aids is the terrain data that is used by processing algorithms to identify and remove errors in other sensor data, and estimate environmental effects on military systems. The use of high quality digital terrain data enables the employment of powerful algorithms for automated exploitation of sensor data in tactical decision aids. But the use of digital terrain data also poses little understood pitfalls when simulation is used in the development of these systems. Information Extraction and Transport, Inc. (IET) proposes to develop methodologies for generating realistic simulated terrain from a set of attribute specifications, where the attributes may be geographic attributes (elevation, slope, roughness, features, etc.) or terrain data quality specifications (accuracy, resolution, completeness, currency, etc.). These methodologies will provide the functionality for a terrain product simulator that can generate simulated terrain products with known departures from ground "truth" terrain, or realistic simulated terrain data according to geographic specifications. IET's use of probabilistic models ensure that there are realistic relationships between features and between attributes of related features in the simulated data. Information Extraction and Transport, Inc.'s successful completion of the Phase I research will generate the following results: 1) a knowledge base of Bayesian Network models that describe the relationships between geographic variables and Bayesian Network or graphical data quality models that quantify the differences between real world terrain variables and the representations coded in standard terrain data products; 2) algorithms for exploiting the knowledge base, that can simulate the information content of standard terrain data products with user specified errors or uncertainty. The algorithms will include implementations in a high level language like Mathematica, Matlab or IET's JSPI script; 3) a high level functional design for a terrain product simulator; and 4) a concept for the use of the terrain product simulator, for evaluating the impact of terrain data quality on the performance of decision support systems. These results will lay the groundwork for a capability that is not currently available, developers of decision making systems, as well as terrain data producers, that will allow them to scientifically evaluate the impact of terrain data quality on decision support systems. One path to commercialization for the methodology proposed lies with commercial mapping software vendors such as ERDAS, ESRI, and Laser-Scan. For example, IET could provide an add-on package to existing GIS software, accessible through their APIs, that would generate simulated content. In that case, some large segment of their current customer base would be an instant market. At the appropriate time in the commercialization plan, IET will approach vendors to form partnerships and licensing agreements.

Title:Synthetic Terrain Generation Employing Wavelet Based Multi-Resolution Polygon Meshes
Abstract:The U.S. Navy needs systems that generate highly realistic, fully and partially synthetic terrain data for training, simulation, and the evaluation of various terrain sensors. Synthetic terrain data is required to simulate areas for which high-resolution data cannot be extracted for political or practical reasons. This system must be able to export the information in a variety of standard formats, including SEDRIS and SDTS. In response to this need, Physical Optics Corporation (POC) proposes to develop a new Fractal Extrapolation Wavelet Synthetic Terrain Application Recursive (FEW-STAR) system. FEW-STAR will employ wavelet-based, polygon-mesh, surface representations coupled with a database containing the statistics of similar terrain types to add detail via wavelet interpolation that incorporates appropriately tailored random functions providing the detail coefficients. FEW-STAR will repeat this process recursively for each resolution level. Rivers and other large-scale natural and man-made structures will be added to the map by a global monitoring module that controls overall connectivity and orientation of features. This module will be augmented by an expert system that employs fuzzy logic to place discrete foliage and man-made artifacts. In Phase I, these tools will be integrated into a prototype that facilitates the interactive specification of the desired terrain. The generation of realistic high-resolution terrain data is increasingly essential for the fields of simulation, computer generated imagery, and electronic games. The capacity of the proposed FEW-STARS to generate arbitrarily detailed terrain in a semi-autonomous manner or add synthetic detail to existing data will be of immense utility to interactive game development and computer generated graphics for film and high-definition television. Additional commercial applications include videography, remote sensing, mapping, and GIS.

Title:Multifunction, High Resolution, High Frame Rate Infrared Sensor
Abstract:Infrared sensor technology has proven to be a key component in the development of advanced systems for target acquisition, tracking, interception, and destruction. These systems require advanced infrared sensors with 640 by 512 or greater spatial resolution, with simultaneous integration (snapshot), and readout rates of 400 frames per second or greater, including high speed windowing mode capability. Sensors of this type are not currently commercially available. Innovations in high-speed multiplexing and low power design are essential to realize these devices. Two key subcomponents are proposed to be developed for the high-frame rate infrared focal plane array (HF-FPA); these are the readout integrated circuit (ROIC), and the infrared detector (InSb or InGaAs). Indigo proposes to extend its family of high performance focal plane arrays by developing a large format, high speed, multiple output, sensor. During the Phase I Indigo will perform a trade study to establish the specification, architecture, windowing modes and demonstrate feasibility and performance of the HF-FPA. The Phase II is divided into nine major tasks: preliminary design, critical design, ROIC fabrication, ROIC characterization, wafer test, detector material, detector processing, hybridization, and HF-FPA testing. High-performance and high-resolution infrared focal plane arrays (IR-FPAs) with 640x512 or greater spatial resolution, with simultaneous integration, and readout rates of 400 frames per second or greater are not currently commercially available for target tracking and range applications. Indigo Systems Corporation proposes to develop large format sensor implementing innovative high-speed multiplexing architecture with low power design and multiple outputs for high-speed IR-FPA system applications.

Title:Multifunction, High Resolution, High Frame Rate Infrared Sensor
Abstract:A program to develop an advanced multifunction, high resolution, high speed sensor capable of operating in the MWIR or LWIR bands is proposed. The proposed system builds upon Surface Optics? real-time hyperspectral imaging activities, modifying the high-speed camera electronics developed for the real-time hyperspectral imagers, and integrating them with Rockwell Scientific?s brand new TCM6504 high-speed 512x640 FPA. Capable of 200 frames-per-second (fps) operation at 512 x 512 resolution, and 50,000 fps when windowed down to 32 x 32 resolution, the proposed imager is ideal for a wide variety of applications, including detection and tracking. As part of the phase I effort, inclusion of super framing (variable integration time for increasing intra-scene dynamic range) and multispectral capability based on current work at Surface Optics will also be investigated. Leveraging proven electronics and an existing focal plane rather than developing new electronics and a new focal plane ensures that this effort will produce a high performance imager by the end of the anticipated Phase II effort. By building on Surface Optics Corporation?s and Rockwell Scientific?s combined decades experience in high-speed imaging system development, sensor development, and algorithm development, the proposed program will produce a new High-Speed IR (HiSIR) imager of unsurpassed capability, with varied military and commercial applications. By developing a new high-speed, high-resolution MWIR/LWIR imager, potentially with multi-spectral capability, the proposed effort will dramatically increase the military?s ability to perform real-time passive and active detection and tracking. Using the system?s integration time synchronization will also enable high-speed ranging, making HiSIRs ideal for targeting and seeker applications. Potential non-threat sensing applications include remote sensing, surveillance, pollution monitoring, plume analysis, medical diagnostics, and industrial production control.

Title:A Versatile Droplet Sizing Spectrometer for Aerosol Hygroscopic Growth Measurements from Research Aircraft
Abstract: There are currently no viable techniques for airborne observations of the size-resolved hygroscopic growth properties of ambient aerosols. The change in size of ambient particles with relative humidity significantly impacts the global atmospheric radiation budget, regional visibility and wet deposition of pollutants. This work focuses on the development of a new method to measure size-resolved water uptake by aerosols that employs differential mobility analysis in-concert with multiple humidification and optical sizing steps. The particle size range and relative humidity limitations of current techniques are addressed by allowing a much broader size range and multiple humidities to be explored over timescales relevant for aircraft sampling. The new instrument system will be designed to operate in a fully automated fashion for field-deployment on the Navy CIRPAS Twin Otter. The measurements will allow local vertical profiles to be made to investigate the role of particle-bound water in determining column radiative properties and for intercomparisons with satellite-derived optical depths. Overall, the new technique will provide results relevant to improving understanding of the impacts of ambient particle hygroscopic growth on radiative transfer, cloud droplet formation, and to validate new aerosol thermodynamic models. The results from the proposed measurements will help validate satellite retrievals of aerosol optical properties. Given the complex relationship that has been observed between ambient particle size, composition and hygroscopicity, direct measurements of water uptake as proposed here are needed. Humankind's activities may be perturbing cloud properties through changes in the ambient aerosol that serve as CCN. Results from the proposed measurements would provide direct input to models attempting to simulate cloud droplet growth and activation for a variety of ambient aerosols. Furthermore, many of the problems associated with existing hygroscopic growth measurement techniques are alleviated by design innovations in the new system proposed here. Numerous research groups in the US and Europe are potential purchasers of the new water uptake measurement technology. NSF, DOE and NOAA operate research aircraft with state-of-the-art aerosol instrumentation and would be potential customers. Future versions of the instrument could be miniaturized for autonomous operation on small remotely piloted aircraft and drones. The smaller device could find extensive use in DOE Atmospheric Radiation Measurement (ARM) program field studies and other remote applications. Although the new technology will be geared toward aircraft measurements, the system will also be capable of ground-based operation. As the EPA promulgates new standards for ambient particulate matter loading, new techniques for understanding the properties of ambient aerosols will be required. The new EPA standards are being driven primarily by the health effects of ambient particles, although visibility reduction is another key issue. The proposed autonomous water-uptake measurement technology is pertinent to both health and visibility impacts of ambient aerosols, and there may be opportunities for large commercial markets that include municipalities and regional air quality monitoring districts. Future, lower-cost versions of the technology could be optimized for ground-based monitoring applications. In the wake of September 11th, the need for new technologies to address bio-warfare aerosols has increased. The new water-uptake measurement system has numerous potential applications including laboratory studies to understand how biological agents respond to increased RH so that atmospheric transport and deposition of these compounds within human airways can be properly modeled under various release scenarios. The current water uptake system design could be adapted for application in the area of bio-aerosol detection by comparing simultaneous ambient number size distribution and hygroscopic growth measurement results to known hygroscopic response and size characteristics of bio-agents studied in the laboratory. Pharmaceutical companies could also use the technology to gauge the human-airway deposition efficiency and deep-lung dose delivery effectiveness of an aerosolized drug-delivery system. Although the system proposed here does not have integrated chemical composition measurement capabilities, BMI is working on a new technique for on-line composition measurements that could be integrated with the proposed water-uptake system in the near future.

Title:Micro Air-launched Expendable Meteorological Sonde (MAXMS) with Selective Availability Anti Spoofing Module (SAASM)-compatible GPS
Abstract:Phase I research will be conducted to prove the feasibility of developing a Micro-sized Air-launched Expendable Meteorological Sonde (MAXMS) for both military and research purposes. The proposed research will investigate unique meteorological measurement requirements and engineering solutions and quantify the accuracy that can be obtained using Micro-sized form factors. The work will include investigation of newly developed miniature GPS technology capable of providing DOD approved Precision Positioning Service (PPS) security. A preliminary design will be developed for an instrument that can be launched from standard aircraft countermeasures dispensers and that can achieve the required measurement accuracy. Optional work will validate conceptual designs to speed development of prototypes during Phase II. By deployments from Unmanned Aerial Vehicles (UAVs), and optionally from manned aircraft, using existing Military dispenser technologies, MAXMS will enable four-dimensional (4-D) measurement and mapping of meteorological parameters in the atmosphere. This can be done spatially in three-dimensional (3-D) space through deployment of MAXMS that measure as they descend at different deployment locations and temporally (now 4-D) through deployment of MAXMS at different times. Atmospheric meteorological conditions (temperature, humidity, wind speed and direction) affect numerous types of military activities. These include: (1) operations with surface watercraft (near surface weather conditions), (2) low and high altitude fixed and rotary wing aircraft operations (4) aerial and satellite reconnaissance, (5) use of guided weapons and countermeasures systems deployed from high altitudes, (6) use of search and fire control radar by ships and aircraft and (7) precision air drop of personnel, equipment, supplies and unattended ground sensors. There are significant non-military research, scientific, and environmental monitoring applications for an MAXMS. Use of an MAXMS deployed from manned or unmanned aircraft can provide academia and agencies such as the Environmental Protection Agency (EPA) an important means of measuring and modeling atmospheric conditions related to movement and dispersion of pollutants. Industry can use MAXMS's to predict dispersal and transport of accidental chemical releases into the atmosphere and aid in determining mitigation methods. These applications indicate a potentially large market for future variants of the MAXMS designed for civilian use . The measurements would also be employed scientifically for collection of research data and predictive model development and validations.

Title:A Temperature Sensor Array for the Determination of Sound Velocity
Abstract:Areté Associates proposes to develop a 24-point array of temperature or temperature/conductivity sensors for use in the Tactical Acoustic Measurements and Decision Aid Environmental Sonobuoy Program (TAMDA) sonobuoy. The pre-deployed array nests in a 2"D X 10" cylinder residing in the TAMDA sonobuoy. The array deploys to a maximum depth of 300 meters, and will measure continuously for a three-day period. The development of this environmental measurements array satisfies the requirements of the Advanced Estimation of Sensor Performance and Multistatic Active Systems projects under the LASW FNC, as outlined in the SBIR solicitation topic N03-117. The measurement system employs unique deployment, communication, and power bus schemes. The system will use little power, and it will integrate into the TAMDA buoy acquisition system via a Control Unit that remains with the deployment canister. Under Phase I, Areté Associates will verify the feasibility of the conceptual design for a 24-element temperature array and will breadboard and test the sensor and control-unit circuitry. For the Phase I option the addition of a conductivity sensor will be investigated and conceptually designed. The goal of Phase II will be the limited production and testing of a small number of the actual measurement arrays. Areté Associates will transition the sensor system to the existing US Navy TAMDA sonobuoy program. Therefore the commercialization strategy is to integrate Areté's developed technology into that community. Areté's unique communications and power bus approach within the array appears to have applications outside of the development of the particular array. All varieties of expendable hydrographic sensors with either military or commercial use could be made less expensive as a result of the bus scheme to be developed under this proposed effort.

Title:Development of Sound Velocity Profiling LIDAR
Abstract:This proposal by EOO, Inc addresses the development of a remote optical sensor that directly measures profiles of sound velocity in water along its line of sight. With scanning of the sensor's line of sight, a 3-dimensional mapping of the sound velocity in the water volume can be obtained. The sensor proposed for development is laser induced Brillouin scattering, a technique that uses Doppler frequency analysis of the Brillouin backscatter. The general technical objective of our proposal is to greatly increase the Technology Readiness Level of remote 3-dimensional mapping of underwater sound velocity to support anti-submarine warfare (ASW) sensor systems. Specific objectives of Phase I are: (1) Review the concept in the context of currently available technology; (2) Define critical technology that will enable or enhance sensor performance; (3) Develop a physics based model and a conceptual sensor design that optimizes performance for platform imposed constraints using currently available technology; (4) Create an implementation plan for Phase II that will result in the fabrication and testing of a breadboard prototype instrument; (5) document the value for ASW sensor performance. The breadboard prototype resulting from this effort is expected to lead to early operational utility demonstrations aboard Virginia class submarines.

Title:Scene Model For Low Observable Infrared Surface Combatants
Abstract:The next generation of surface combatants will be designed with stringent requirements on efficiency, performance, and survivability. Their development requires innovative technology and capable virtual design tools. ThermoAnalytics proposes to create a virtual prototyping thermal design and infrared scene rendering tool by building on the U.S. Army standard infrared analysis code MuSES (Multi-Service Electro-optic Signature) and commercial thermal analysis tool RadTherm. This innovative tool will support signature treatments including water wash systems, exhaust suppression, special coatings and others. The tool will include options to incorporate CFD results for accurate modeling of convection off exterior ship surfaces as well as verified convection correlations tailored for ship modeling. Since plume modeling is an important factor in infrared signature management, ThermoAnalytics will create a streamlined CFD (computational fluid dynamics) interface with its state-of-the-art thermal solver. To accurately model the sea surface, a ship wake model will be integrated with Cox-Munk sea surface and structured sky models. Both the target model and sea surface will be rendered using a multi-bounce ray tracer that supports multi-lobe and anisotropic BRDF (bidirectional reflectance distribution function) models. The proposed modeling and simulation tool will be reliable, portable, modular, and physically accurate enough to achieve LO design levels. The proposed engineering tool can be applied to the design of both new vehicles and retrofits of existing vehicles. This innovative tool, tailored to meet the design needs of the Navy's next generation of surface combatants, can be used for vehicle subsystem design, thermal management, propulsion system development, infrared and visual signature prediction, and to analyze the cost and signature impacts of design decisions. With its ability to model the whole environment and its impact on vehicle performance through its natural environment models and integrated CFD, the tool can assess how a vehicle will perform under differing climates, weather, and operating conditions. Properly designed thermal and signature management increases the performance, survivability, and reliability of surface combatants. Additional military benefits include mission planning, threat assessment, and signature reduction due to efficient cooling system design and exhaust suppression. Commercial benefits include the application for automotive applications that must be designed for increased efficiency and performance under a wide range of real-world environmental conditions. The code can also be applied to other disciplines including electronics cooling, building ventilation, cooling systems, and aircraft.

Title:Hybrid electric drive for small craft
Abstract:Littoral Research Group L.L.C. (LRG) of New Orleans, Louisiana has teamed with Kinetic Art and Technology (KAT) and its commercialization arm Lynx Motion Technology Corporation to offer a dynamic partnership that integrates world-class naval architecture services with cutting edge, award winning, electrical engineering and design. LRG will use their hydrodynamic planing codes to analyze the sea-keeping and powering performance of the 7-meter RHIB, to determine the final system requirements, and to determine location of all major equipment in order to optimize the sea-keeping and powering efficiency of the 7-meter hybrid electric RHIB. KAT/Lynx brings their patented SEMA motor technology that offers efficiencies up to 99% at loiter speeds along with their expertise in system controls. LRG will review all major components, engine, gear, sterndrive/outdrive, and propeller and make recommendation for replacement, redesign and integration as an integral system. Currently, the Navy is developing a fleet of Unmanned Surface Vessels (USV) in the support of the Future Naval Capabilities (FNC) mandate. This fleet is being developed from the 7-meter and 11-meter RHIBs because they have shown the capability to support such operations as mine countermeasures, amphibious warfare support, communication relay with UUVs, and a significant number of other functions. LRG views the research, development, and deployment of the hybrid electric 7-meter RHIB as a large step toward a fully electric, fully autonomous fleet capable of amphibious warfare support. Beginning in the year 2006, marine diesel engines over 37-kW will be required to meet new clean air standards. Recreational marine engines contribute to ozone formation and high PM (particulate matter) levels, especially in marinas, which are often located in areas with air-quality problems. The use of the hybrid electric technology to assist in meeting the new standards will have a profound positive effect on the air quality in our marinas and National Parks. One commercial application of an electric propulsion system is a "pontoon boat". The pontoon boat has several advantages over conventional hulls with respect to electric propulsion: 1) The benefit of a sizeable deck area that can accommodate a large number of low profile batteries stored under-deck, 2) The builder will have the option to install multiple electric motors in the pontoons or a single one on centerline, and 3) The design flexibility that is afforded by a diesel engine/generator will allow the builders to move toward a more modern and open architecture. In addition to the commercial applications, there are military applications for pontoon type vessels. One such example would be in mine countermeasures where sizable deck area would provide a large stable platform that would easily conform to modularity requirements and where the long slender pontoons provide unmatched form efficiency that is inexpensive to construct, easy to store, and potentially "stackable".

Title:Hybrid electric drive for small craft
Abstract:The Navy's small craft spend the majority of their operating hours at either idle or full power. The form of hybrid drive proposed for the 7-meter RHIB is tailored to these operating characteristics while preserving present speed and range capabilities. This type of drive is characterized as a parallel hybrid drive with a large engine and small battery. Other Naval ships and craft may warrant other hybrid electric drive train choices. We have specifically postulated a need for a low-speed (5 knot) range of 10 miles under electric propulsion. We have sized the battery pack at 12 kilowatt hours to provide the required speed and endurance with a 20% margin for wind and wave effects. The proposed battery is a Lithium Ion high-energy pack, includes a thermal and charge management system, and is packaged in a composite container with a total weight of 135 kilograms. Fuel savings are achieved in the present design by operating at low speeds over modest distances without the engine. Low speed operation of the engine is the least efficient part of the engine's operating envelope and significant fuel is burned at these low speeds. Signature implications of this operating mode are obvious. A more efficient propulsion system that will lead to lower operating costs of the 7-meter RHIB. Mission capabilities can be expanded with the silent mode of operation.

Title:Hybrid electric drive for small craft
Abstract:Hybrid electric drive has evolved into an attractive propulsion architecture for many different military applications. It provides these vehicles with improved fuel economy, reduced signatures (audible, thermal and electromagnetic), increases on-board electrical power, and enables design flexibility that is not possible with diesel engine-driven vehicles. UQM has demonstrated these advantages within military vehicles (e.g., Army HMMWV, Air Force ground support, and Unmanned Ground Vehicles) and within commercial vehicles (GM Precept, UPS delivery trucks, John Deere tractors). This diverse hybrid electric vehicle experience provides the knowledge and expertise required to transfer the technology into the 7-meter RHIB Naval platform. UQM proposes to develop a conceptual design during the Phase I program that consists of an off-the-shelf engine mounted to an existing generator, an existing dual propulsion motor, a high voltage battery pack (exceeding 320 VDC), battery management, and power management system. This configuration will enable reduced fuel consumption, reduced signatures, increased electrical power without the need for a separate generator set, and design flexibility due to the small size, light weight, and forward/reverse capability of the electric propulsion system. Hybrid electric drive is an advantageous architecture for the majority of military and commercial boat applications. By focusing this effort on existing technologies and products, the production cost of the system can be minimized to attract commercial attention. For this reason, and because UQM understands procurement cost issues, all tradeoffs performed during the development program will consider cost as the first figure of merit. UQM has established relationships with watercraft and marine engine companies.

Title:New Low Cost Resins Systems
Abstract:Future composite applications for Navy submarines and surface ships requires advanced polymeric matrices that have improved fire, smoke, and toxicity (FST) as compared to the present state of the art composite matrix resins of today. These matrix characteristics, along with the requirement of low cost composite manufacturing, provides a challenge for new resin development. As a first step in the development of matrix resins that meet the goal of Navy FST, is to develop a non-halogenated resin that is capable of vacuum assisted resin transfer molding (VARTM), and has the same or better FST performance when compared to Derakane 510A, a halogenated vinyl ester resin. To develop matrix resins with improved FST characteristics, and capable of VARTM processing, new approaches must be taken in parallel with new materials and formulations. API proposes to focus primarily on epoxy chemistry, and modify these systems using a combination of reactive phosphorous and new compatible silicone compounds. A synergistic effect has been shown for reducing FST properties when both organophosphorous and silicone materials are used in combination. Upon successful completion of this Phase I effort, the low visosity reactive phosphorous and silicone materials synthesized will give the necessary formulating tools too improve both fire and mechanical properties of current F.R. epoxy technology. Proposed technology will offer the following marketing improvements over Derakane 510A vinylester.1)Low emmisions 2)Less smoke generation 3)Less toxic gases during fire 4)Low shrinkage 5)More damage tolerant. Potential commercial applications include: high speed water craft, passanger rail transport, oil rig crew compartments, oil drilling pipe,non-halogenated circuit boards,and earthquake retrofitting of hospitals and government buildings.

Title:New Low Cost Resins Systems
Abstract:There is great anticipation and an urgent need to develop a low viscosity, affordable, non-styrene based, flame resistant resin system similar to the vinyl ester Derekane 510A and curable at room temperature. This resin system, compliments of Dow Chemical, is a Brominated bisphenol and has work quite well relative to confined place. There is a need to find an alternate material that will produce non-toxic gaseous material when subjected to flame. The current halogenated resin has a tendency to breakdown and form acidic fumes which are more dangerous in most cases than the fire itself. The objective of this proposal is to develop a resin system similar to Derekane 510A in every respect except for that fact that it will be non-styrene based and laden with halides. The commercialization strategy of moving the result of this invention to the market is quite straightforward. The strategy will involve forming an Integrated Product Team (IPT). As a matter of fact the members of the team will include DuPont Electronic Technologies, whose main market objective is to service the electronics industry with highly branched, low metal polymers with photo-resist capability. Following a successful development of the base material in Phase I, DuPont will play a significant role in Phase II of the project. It will be an easy selection process for DuPont to select an end user of the product from their impressive customer list. DuPont also has ISO 9000 certified manufacture plant in Dayton, Ohio to scale up whatever material is developed through this effort. To date, more than nine resins have been commercialized by A.T.A.R.D. Laboratories. The success and experience gained in establishing a commercial base for former products will enable us to transition the technology into a commercialized product.

Title:New Low Cost Resins Systems
Abstract:Develop and test unsaturated resins that incorporate unique low cost chemistries that provide for greatly improved fire performance without the use of halogens or bromines. These resin systems are to be compatible with traditional open mold manufacturing processes and closed processes including vacuum infusion. These systems would be low cost alternatives to phenolics and epoxies with reduced processing costs. The commercial applications would range from public transportation and industrial applications to aviation applications for commercial aircraft interior components.

Title:Non-Intrusive Underwater Pressure Sensor (NUPS)
Abstract:Underwater pressure measurements on submarines, weapons, and propulsors are important for performance and acoustic analysis. Many current pressure measurement solutions are intrusive (i.e. disruptive to the flow field) and/or expensive. Midé proposes to make modifications to a commercial, of the shelf, (COTS) system which will provide an inexpensive solution with an extremely thin (0.007") and conformable profile. The system, based on a pressure sensitive ink, has a matrix of sensing elements, with a spatial density as high at 62/cm^2, and encpsulated in flexible poyester film for protection. Specific spatial densities and measurement ranges can be changed by selecting between different available sensors. Phase I work involves ru
