Title:Lightweight Materials for the Expeditionary Fuel System (EFS)
Abstract:The Expeditiary Fuel System (EFS) concept was designed to be a modular fuel tank system capable of deployment aboard a multitude of ships, ground vehicles and aircraft. The EFS is comprised of individual tank modules mounted to a unique transport pallet. While the concept was successfully demonstrated in FY 2001, the prototype tanks were too heavy to meet requirements for production. The Marine Corps needs a system comprised of individual tank modules that can break down for transport aboard amphibious ships. The fuel tank modules must be affordable, lighter and more robust than the current aluminum EFS tank modules. Texas Research Institute Austin, Inc. proposes to develop a cost effective, lightweight, durable, modular, composite EFS fuel tank that will be man portable, easy to assemble and disassemble, and corrosion resistant, significantly reducing maintenance and repair costs. The composite EFS tank module will be constructed from composite materials that will meet all U.S. Navy shipboard requirements, operational loads and environmental exposures. The use of composite materials will provide a low cost, lightweight EFS tank module that will have a long, corrosion free, damage tolerant service life.

Title:Affordable Lightweight "Integral" Composite Material Design for The EFS Module (1000-305)
Abstract:Triton Systems Inc. proposes a lightweight, low-cost, composite material design to replace the current heavy aluminum system for the expeditionary fuel system (EFS) module. The composite EFS will be fire- retardant, corrosion resistant, and environmentally friendly. Triton will engineer and optimize the advanced thermoplastic or thermoset polymer matrix composite (PMC) material design for lightweight, rendering the EFS module man-portable. The lightweight EFS module will provide the Marine Corps with capability to efficiently conduct bulk liquid throughput and distribution on the battlefield. With its high strength-to-weight ratio, comparable stiffness, and energy absorption properties, engineered PMC offers significant potential for weight savings (>35%), over the current aluminum design. The composite EFS module will be fabricated using Triton's Controlled Resin Injection Molding Process (CRIMP), a modified version of Vacuum Assisted Resin Infusion Molding (VARIM) process, which is the most cost-effective integral manufacturing process. The process uses closed molds and is thereby environmentally friendly.

Title:Lightweight sandwich composites for improved thermal and acoustic performance
Abstract:In this phase I SBIR program, Advanced Ceramics Research, Inc. (ACR) proposes the development of an innovative, one-step co-curing fabrication process for sandwich composite structures with a flexible insulating material encapsulated by an fiberglass/epoxy face sheet for thermal and acoustic barrier applications. The flexible insulating material has excellent thermal and acoustic properties, is commercially available but its use has been limited due to the lack of structural integrity. The advantage of the proposed method is that in a stitched sandwich construction it can provide exceptional thermal and acoustic properties at half the thickness of current fiberglass/epoxy composites. ACR's patented water soluble tooling material will be used in the fabrication of sandwich panels with complex geometry. This provides the opportunity to make sandwich panels to fit any given profile further reducing size and weight. The composite panels can also be fabricated for modular construction to provide high repair/replaceablity at low cost.

Title:High Attenuation Thermal Barriers for the AAAV (MSC P1B16-327)
Abstract:Structural vibrations and heat produced by high output turbo-machinery can adversely impact the performance of nearby personnel and contribute to costly and premature failure of equipment within the AAAV. The product of the SBIR program outlined in this proposal is a lightweight composite structural enclosure designed to provide maximum acoustic attenuation and thermal shielding. The design concept proposed by Materials Sciences Corporation integrates two synergistic noise control technologies into a sandwich construction in which constituent materials, layering sequences, fiber architectures, and a structural geometry are tailored to maximize thermal shielding and transmission losses at a minimum weight. The feasibility of our integral acoustic attenuation concepts into low thermal conductivity panels will be demonstrated by designing, fabricating and testing five panel configurations to assess their performance relative to the AAAV performance goals.

Title:Passive Acoustic-Thermal Vacuum Insulation System (PATVIS)
Abstract:Performance requirements of the Advanced Amphibious Assault Vehicle (AAAV) have resulted in hot and/or noisy equipment inside the AAAV with sound levels over 120 dBA. Current methods are inadequate to allay these extreme conditions that present physical and operational hazards to Marines engaged in combat maneuvers. TAI is proposing a highly innovative concept to provide a new level of performance in combined thermal insulation and acoustic attenuation. Advances in the areas of thermal insulation and noise suppression are available through the use of vacuum insulation panel (VIP) technology. VIP has exceptionally low thermal conductivity resulting in thermal performance that exceeds AAAV requirements by as much as an order of magnitude. Because vacuum is the ultimate attenuator for sound, VIP provides a great potential for noise reduction. However, no study has been conducted to determine the effectiveness of VIP with respect to passive acoustic attenuation. TAI proposes to conduct such a study in this Phase I effort. Additionally, state-of-the-art viscoelastic materials can be packaged with VIP providing a synergistic combination of properties to achieve a solution for the AAAV.

Title:Holistic Circuit Card Testing using Nanoscale Sensors
Abstract:This proposal describes work efforts culminating in the design and eventual (Phase II) development of a prototype circuit card tester utilizing nanoscale sensors combined with laser and optical techniques to analyze circuit cards as an entire, complete system of components, circuit paths, and connectors rather than the sum of its individual parts. This revolutionary new approach has been made possible through the development of nanotechnology-based devices that can sense characteristics and changes at the molecular level, lending itself to the detection of entire classes of anomalies and failures that are not detectable using currently available automatic or other test equipment currently performing end-to-end diagnostic testing of individual signal parameters. These characteristics include degraded operational performance resulting from the aging of components as well as from corrosion, wear, stress, and other effects that may accumulate in the field. Our approach focuses on the development of a small footprint, man-portable lightweight system capable of being deployed via Humvee or remotely controlled ground or air vehicle to remote locations.

Title:Microscopic Damage Detection and Remaining Life Assessment of Printed Circuit Boards
Abstract:Field inspection of printed circuit boards (PCB), and assessment of their condition is critical for the readiness of military equipment. A new technology is needed that is portable and able to inspect PCBs, yet can perform sophisticated characterization of defects, and predict the remaining life of the electronics. The technology proposed by RMD could revolutionize the nondestructive evaluation (NDE) of PCBs and circuit components using inspection at the microscopic level to predict aging effects in PCBs. The technology is based on the use of a two-dimensional, high density array of microscopic MR (magnetoresistance) sensors for detection and mapping of both induced magnetic fields, and electric currents in PCBs and components. Analysis of the magnetic fields allows detection and imaging, at the microscopic level, of parameters such as electrical continuity, trace thinning, short circuits, and aging effects. The defects will be mapped and imaged in three-dimensional space so that the localized electrical parameters can be correlated with the nature and severity of the defect. RMD has assembled a team with the technical expertise, and experience to successfully develop the proposed technology. When fully realized, the new technology will detect defective circuitry, and analyze the reliability of critical DoD systems.

Title:Demonstration of a Portable Water Purification Device for the USMC
Abstract:A lightweight portable water purification device has been long sought by the US military. Mainstream has been hard at developing such a lightweight purification device since 1989, and has finally developed the configuration for a small portable device that will meet or exceed all the performance requirements of this USMC solicitation. This device, which uses a unique and patent-pending configuration, has already been designed by Mainstream and is discussed in this proposal. At 24 ounces dry-weight, this device can produce 1.5 liters of purified water in as little as 45 seconds. Cleaning is simple and straightforward. Phase I includes the fabrication and demonstration testing of this lightweight water purification device, which includes a 1.5 liter water storage capacity. Mainstream has been developing this technology for many years and we will continue to put our own Internal Research and Development funds into this project, because of the tremendous commercial potential for this technology. Phase I will allow a full demonstration of the concept's feasibility, and provide performance comparisons to alternative approaches. The Phase II effort will address DoD field testing, and prototype refinements for an actual USMC application.

Title:Man Portable Water Purification System
Abstract:In today's military, Marines must be highly mobile and carry all necessary equipment and supplies with them. A major limitation to mobility is the need to carry fresh water. An individual Marine must carry 12 to 24 pounds of water for each day they will be in the field without re-supply. It would be far better to be able to purify locally-available water, but no technology exists that will allow Marines on the battlefield to purify water in every environment. Existing, commercially-available water purification devices can readily handle large particles, bacteria, protozoan cysts and viruses, but currently there are no man portable systems for purifying brackish or salt water. In this proposal TDA Research, Inc. (TDA) will build a portable water purification system that includes desalination. The overall Phase I work plan is to build a prototype system, and then test its desalination capacity. From this prototype system we will be able to identify the advantage of desalination process and address the problems. We will do an engineering analysis to analyze the cost and performance of the system and allow us to design and build improved systems in Phase II.

Title:Arrayed, Wide Bandgap Semiconductor Based High Intensity LED for Area Denial
Abstract:Nanohmics proposes to develop a compact, efficient, high luminous intensity strobe light that emits in the 520 to 550 nm spectral range using gallium nitride (GaN) emitters. The design will be developed around an array of GaN surface mount chips for a 180 degree illumination pattern of light luminous intensities capable of temporarily disabling or disorienting potential adversaries (i.e. flashblinding). Nanohmics will also investigate the use of broad area emission from optically doped aluminum nitride as a down converter to optimize the emission wavelength for optimal eye sensitivity. The system will operate from rechargeable batteries, contain embedded circuits for variable frequency pulse generation, and an integrated radio-frequency link for remote programming and reporting of individual strobe systems. All strobe systems could then be operated from a single control unit for wide area coverage. Systems can be strategically placed to maximize probability of disabling the target(s). In Phase I, Nanohmics will determine optimal device properties and configurations. Based on this study, a prototype design of the system will be generated. During the Phase II, Nanohmics will take the most promising materials system and construct a prototype device optimized for Navy area denial requirements.

Title:Adaptive Noncoherent Dazzler Floodlight
Abstract:A noncoherent source of light is needed as a nonlethal weapon to disable opposing forces with minimal casualties. To address this need, Physical Optics Corporation (POC) proposes to develop a new Adaptive Dazzler Floodlight (ADF), based on a noncoherent compact source and a dazzler. ADF will deter opposing forces at controllable levels varying from repel to incapacitate. Its noncoherent eye-safe illumination will cause no permanent injury to personnel. In the ADF approach, the output power is controlled by switching on a variable number of light emitting diodes (LEDs), the outputs of which are collimated by nonimaging solid collimators. The ADF also includes a xenon arc lamp as a conventional floodlight whose output is collimated by an innovative POC omnidirectional collimator and directed by a conical mirror. The xenon lamp outputs the floodlight beam through the ring-shaped outer area of the ADF aperture, whose central area is occupied by the LED dazzler assembly. In Phase I, POC will demonstrate the feasibility of the ADF technology. In Phase II, an engineering prototype will be developed and tested.

Title:Chromate-Free, Zero Volatile Organic Compound Primer for Amphibious Vehicles
Abstract:The objective of the program is to demonstrate through resin synthesis and system formulation a chromate-free, zero volatile organic compound (VOC) primer that meets the corrosion, physical and environmental resistance performance requirements for the exterior surfaces of amphibious assault vehicles. Luna Innovations, Inc. will develop a novel VOC-free binder system consisting of a water-dispersible glycidyl carbamate functional epoxy resin. The crosslink-functional coating will have the excellent physical and barrier properties of a two-component epoxy resin combined with the durability and flexibility of polyurethane. Incorporation of low-cost, environmentally acceptable plant-based extracts that exhibit remarkable corrosion inhibition into the primer system will provide the required corrosion protection. Luna will demonstrate the performance properties of the coating system through the appropriate standardized military tests and in direct comparison to existing chromate-bearing military qualified products. Substantial cost and performance benefits with concomitant decreased environmental impact will be realized from the novel high performance system formulated to conform to existing logistical and operational requirements.

Title:A Low-VOC Chromate-Free Primer
Abstract:The Advanced Amphibious Assault Vehicle (AAAV) is the United States Marine Corps' newest weapon system that moves three times faster and carries greater firepower than the current amphibian vehicle. The spectacular performance of the AAAV is due in part to the structural use of Aluminum alloy 2519-T87. Aluminum alloy 2519 is an Al-Cu alloy developed as a weldable material, and has ballistic penetration resistance superior to the previously used Al-Mg 5xxx series armor alloys, such as 5083. Unfortunately like other Al-Cu alloys (e.g. Al2024-T3 used in aircraft), alloy-2519 is highly susceptible to corrosion. Thus, high levels of corrosion protection are needed in order to minimize general corrosion, largely in the form of pitting and filliform corrosion and thereby minimize the AAAV's operating and support costs. TDA Research, Inc. (TDA) has developed a novel releasable corrosion inhibitor that offers exceptional protection for high strength Al-Cu alloys. TDA will incorporate these new corrosion inhibitors into a low-VOC epoxy and combine their use with the Navy's hexavalent-chromate-free trivalent chromium conversion coating to make a highly effective corrosion protection system.

Title:Non-Woven Textile Technologies
Abstract:The main objective of this proposal is to investigate the use of nonwoven textile composite fabrics in military applications such as battledress uniforms (BDU), chemical and biological agents protective uniforms (CBPU), tents, tarps, coverings, bags and other miscellaneous items where conventional woven and knitted fabrics are currently used. The opportunity is to create innovative and lightweight nonwoven composites that will enhance the functional performance of current military uniforms and other textile applications while retaining properties of wear, durability and printability at improved life cycle cost. The possibility of improving the current design of BDU to incorporate additional protection against chemical and biological agents while reducing the heat stress will also be explored. This phase I proposal will investigate the potential uses of various nonwoven textile technologies such as spunlace, spunbond, melt blown, ultrasonic-bonded and needle-punched for use in the US military. The nonwoven composite fabrics will be tested for functional properties such as durability, air permeability, printability and launderability.

Title:EPIC (Electromagnetic Personnel Interdiction Control)
Abstract:The Marine Corps has a requirement for a non-destructive stun weapon that would render a hostile war fighter ineffective for a period of time. There is significant political and military interest in such a capability. In addition, the ability to remotely incapacitate a human being without permanent damage would be a landmark event in the field of civil law enforcement. The desirability of waging bloodless war to counter threats to national security is virtually limitless since both military and civil authority could determine a priori when and if loss of human life is necessary. IVC proposes to investigate the use of beamed RF energy to excite and interrupt the normal process of human hearing and equilibrium. The focus will be in two areas. (1) Interruption of the mechanical transduction process by which sound and position (relative to gravity) are converted to messages that are processed by the brain. (2) Interruption of the chemical engine which sustains the proper operation of the nerve cells that respond to the mechanical transduction mechanisms referenced in item (1). Interruption of either or both of these processes has been clinically shown to produce complete disorientation and confusion. Second order effects would be extreme motion sickness.

Title:Multi-Band Air Defense/Air Search Radar
Abstract:Multi-band phased array radar systems that contain solid-state transmitter sources and low-noise preamplifiers for transmission and reception are preferred over the conventional airborne radar antennas. The active array radar offers the advantages in the areas of power management and efficiency, reliability, signal reception, beam steering target detection and system performance. The current phased array radar design is narrow-band, very complex, expensive and less efficient. In addition, the size, power dissipation and the weight problems have inhibited the development of multi-band phased array antenna systems so far. This proposal describes the development of multi-band active radar system based on wide-band multi-functional antenna elements and very low loss, wide-band, and high power handling phase control circuits for beam scan. The new phase shifter design is based on micro-strip feed lines perturbed by the proximity of voltage controlled piezoelectric transducer (PET). The insertion loss of phase shifter is less than 1dB up to 20 GHz. The new active array radar design will have significant improvement in performance, size and efficiency.

Title:Multi-Band Air Defense/Air Search Radar
Abstract:Next generation radar systems will be required to perform multiple missions. For example tactical ground based systems will be called upon for supporting air defense with target identification and for air traffic control. Additionally the same system will be required to perform hostile weapons locating together with cueing of friendly weapons. It is essential that all of these missions be accomplished effectively with a high degree of performance and readiness. Providing the ability for the radar system to operate in more than a single frequency band enables realizing optimum multi-mission performance. Lower frequencies generally provide superior long range surveillance capabilities while higher frequencies excel for angular accuracy and target discrimination. Novel implementations for multi-band radar are essential to support system performance growth and system readiness, and to realize attractive total ownership costs. Sensis Corporation proposes to develop the technologies for realizing multi-band active phased array antennas for high mobility multi-mission radar systems. For Phase I of the proposed program, Sensis will leverage our expertise to formulate the dual-band radar system operational concept, architect the active phased array, establish key Transmit/Receive channel requirements, and derive an active array T/R building block concept.

Title:Enhancement and Optimization of a Lobed Mixer for AAAV
Abstract:CFDRC proposes to reduce the thermal and acoustic signatures of the AAAV engine exhaust with a minimal loss in installed engine performance by designing, optimizing and testing a passive, lobed mixer/ejector system. A design, analysis and test cycle based upon accurate and validated Computational Fluid Dynamics analyses, parametric design optimizations and detailed testing is proposed to reduce the detectable thermal and acoustic signatures. During Phase I our efforts will focus on isolated ejector analyses and tests that will be used to assess enhancements to the lobed mixer. This will be expanded during Phase II by optimization of the installed mixer system performance and signature reduction via consideration of flow features upstream and downstream of the mixer for various engine operating conditions and environments. The AAAV design currently incorporates an untested and uncharacterized, passive, lobed mixing device that conditions engine exhaust flow to reduce the thermal and acoustic signatures. The proposed work will characterize the existing system, and at completion of Phase II, result in an optimized design that reduces the thermal and acoustic signatures without significant impact on space, weight and power. CFDRC has applicable experience assisting GDLS in the design and analysis of such systems for other combat vehicles.

Title:Reduction of Ground Vehicle Observables Through Carbon Foam-Based Exhaust Treatment
Abstract:This project addresses the topic of Reduction of Ground Vehicle Observables. The use of carbon foam to reduce engine-related observables will be investigated. Carbon foam offers high specific thermal conductivity while providing better structural properties at elevated temperatures than traditional heat exchanger materials. Carbon foams also resist chemical and environmental corrosion without the need for additional coatings or treatments, making them well suited to abusive environments. Because of the foam's open-celled structure CFOAMr also has the potential to act as a filter for particulate matter. This study will address the reduction of three observables: heat, noise and particulate matter and the impact on cost, weight and performance. The Phase I effort will review design options and analyze their impact on observables, vehicle functionality and performance. Phase II work will construct a prototype to demonstrate the reduction of observables and will address future technological hurdles.

Title:Remote Perimeter Security System
Abstract:This proposal describes the development of an intrusion detection system based on the use of two camera subsystems. The first subsystem, used for basic detection of intruders, is a long wavelength (~8-12um) thermal camera. This camera detects warm objects of any kind, day or night, and constantly monitors a wide field of view (FOV). The second subsystem is automatically activated in response to potential intruders detected by the thermal camera. It consists of two telephoto video cameras capable of imaging detail at large distances to classify the intruder. One camera is primarily for daytime color imaging of the potential intruder. The second camera is Intevac's NightVista intensified low light camera for nighttime classification. An eyesafe parabolic infrared illuminator is used with the NightVista to project focused IR light out to large distances to improve the nighttime image. This system will provide sufficently detailed images such that the software will be able to classify objects as either human or animal.

Title:Remote Perimeter Security System
Abstract:Perimeter surveillance and monitoring is an integral and important aspect of anti-terrorism and force protection. The addition of a large number of sensors to cover the area under surveillance increases the risk of operator inattention and makes cost prohibitive. Current cameras have limited range for object detection or are extremely expensive. Coverage of large areas needs automation to detect intrusions with alarm actions on events.The goal of the proposed work is to build an advanced video imaging based omni-directional perimeter security system. The system will comprise omni-directional cameras and integrated tracking technologies and other sensors, such as slaved Pan/tilt/zoom cameras for target identification. Omni-directional optics to achieve the desired range of detection will also be designed.

Title:Low Cost High Strength High Toughness Corrosion Resistant Materials for Marine Corps Advanced Amphibious Assault Vehicle (AAAV)
Abstract:The Marine Corps Advanced Amphibious Assault Vehicle (AAAV) has a need for low cost titanium alloys for use in major components such as the Hydro-pneumatic Suspension Unit (HSU) and for low cost, high strength, high toughness, corrosion resistant materials for use in other critical components. The Phase I effort will involve trade-off studies on commercial alloys/processes (Ti-6Al-4V investment castings and Custom 465, MP35N, IN718), on near term commercial materials (Ferrium S53) and on far term materials (nanomaterials) to evaluate their applicability for use in selected components for the AAAV. Phase I will also involve testing of the mechanical properties and corrosion resistance of the Ti-6Al-4V castings and the Custom 465 and MP35N and developing preliminary design concepts for the use of these materials in the AAAV. Phase I will provide recommendations of specific materials and/or process substitutions which will achieve cost reduction with equivalent or improved performance over the currently used titanium alloy and steel components. An Option Phase will involve (1) designing the titanium casting process to produce AAAV components and (2) laboratory testing of selected near term commercial materials.

To perform successfully, the material from which these structural components are fabricated must have a balance of properties, including high-strength, high-toughness, good wear resistance, and good corrosion resistance. The best material solutions currently available are either Ti alloys, such as Ti-6-4, or proprietary stainless steel alloys. Ti-6-4 is an expensive material, and a significant goal of this project is the reduction of material and machining costs without sacrificing performance. A well-developed set of computational design tools has already been applied to the design of new stainless steels for aerospace landing gear applications. Under this proposed Phase I SBIR, a series of microstructural toughening strategies will be theoretically assessed to devise stainless steel compositions matching the more rigid corrosion resistance, strength, and toughness properties needed for structural components of the AAAV. A new high strength, high toughness stainless alloy would have dual-use application potential for commercial aircraft and other commercial markets such as marine equipment.

Title:Laser Deposition for Manufacture of Titanium Cast Parts
Abstract:Optomec proposes to develop the capability to use the laser deposition process to provide an alternative for investment casting for aerospace-grade Ti-6-4 components. Previous data suggests that laser deposition can be a viable manufacturing route for these components. We will investigate the mechanical properties of laser-deposited material in thick sections, to determine whether laser deposition can be used for large components. We will use the feedback control sensors of the process to understand defect formation, and determine whether real-time process checks can be used to eliminate defects. We will evaluate the microstructural and chemical properties to ensure compliance with the relevant standards, and we will evaluate non-destructive testing techniques to determine whether they can adequately screen laser-deposited material. The outcome will be an assessment of the process relative to casting, and an identification of components and methods to successfully develop and introduce the technology to the Navy.

Title:Affordable Titanium Structures Using Innovative Casting Technologies
Abstract:This SBIR Phase I effort proposes to develop an innovative, more affordable titanium casting technology based on rammed graphite and hybrid molding technologies. Rammed graphite molding is a lower-cost casting process not traditionally used to manufacture aerospace titanium components, while hybrid molds are a combination of two or more non-traditional molding technologies. This processing approach consists of casting technique of using rammed graphite mold combined with other molding materials to achieve near net shape titanium structures at a lower cost than by conventional investment casting for certain classes of aerospace components. The new process is expected to yield sufficient microstructure, mechanical properties as compared with the current investment casting method, with sufficient part geometrical complexity capability and surface finish when supplemented with added-value fabrication methods.

Title:Incorporation of Analysis Enhancements of a p-Element Analysis Code Required for Implementing the Strain Invariant Failure Theory
Abstract:Historically, the correlation between predicted failure and actual failure of composite aircraft structures has left much to be desired. Current analytical prediction methods often over estimate or under estimate the failure load by 25% or more. Compounding the problem is that the failure location is not consistently identified by the analytical method. The inability to accurately model and predict failure of composite structure has led to a lengthy and costly, test-based certification process. A relatively new failure theory for composites, the Strain Invariant Failure Theory (SIFT), is proving to be far more accurate at predicting failure. SIFT in conjunction with a robust finite element analysis (FEA) tool offer an efficient method aimed at streamlining the design certification process for laminated composite structures. Phase I activities address the necessary enhancements to StressCheckr, a parametric p-version FEA tool, to facilitate the use of SIFT methodology during post-processing. Enhancements include: 1) Add a General Shell element and a Transition element that will enable the connection of a shell to a 3D solid element. 2) Add laminated orthotropic material properties that follow the general curvature of a shell or solid element. 3) Add a Contact element and 3D Fastener element with clamp-up simulation.

Title:Low-VOC, Self-Priming Conformal Coatings
Abstract:Electrically insulating conformal coatings are used to protect electronic components including antennas from corrosion. A low VOC, non-chromated flexible coating is proposed for protecting aircraft antenna components in the corrosive marine environment. Novel elastomeric resins having inherent corrosion inhibiting qualities will be formulated with non-metallic anticorrosive agents to yield self-priming coatings with excellent adhesion to antenna structures, flexibility and high durability. The proposed research seeks to apply a proprietary chemical technology to the formulation of low VOC, non-chromate conformal coating systems that meet the current MIL-I-46058C specification. The proposed anticorrosion formulations will readily form low permeability, conformal films that adhere strongly without the need for priming. The development of new multi-function polymeric additives should significantly improve the formulation properties and allow conventional spray application of the primerless coatings. The new conformal coatings will be tested against conventional solventborne systems for adhesion, electrical insulation and corrosion inhibition. The ability to form adherent, highly flexible and durable barrier coatings over non-ferrous metals and cross polarizer materials without primers would represent a significant advancement in corrosion engineering and aerospace maintenance technology. The new coatings will be thoroughly screened for corrosion prevention, electrical insulation properties, and adhesion according to standard methods.

Title:Environmentally Benign Polymer Coatings for Enhanced Corrosion Protection
Abstract:Aircraft radar antenna systems pose unique challenges to protective coatings. Coatings must not interfere with radar operation, must provide a high level of corrosion protection, and not adversely affect the environment. We propose to develop a novel polymer coating system that simultaneously satisfies these requirements and also provides improved convenience for the application process. The coating will provide additional benefits in corrosion protection of marine equipment, bridges, automobiles, and industrial chemical processing equipment and storage tanks. In Phase I, we will demonstrate the feasibility of the polymer coating system by developing a preliminary coating formulation and demonstrating its ability to provide improved corrosion protection, in addition to its suitability for radar antenna applications. In Phase II, we will optimize the coating formulation and perform field testing.

Abstract:The objective of the program is to demonstrate through resin synthesis and system formulation a single-coat, chromate-free, low or zero volatile organic compound (ZVOC) conformal coating that meets the performance requirements for radar antenna systems. Luna Innovations, Inc. will synthesis novel autoxidative water-based polyurethane dispersions that will facilitate formulation of an air-cured single-component, ZVOC primer. Incorporation of low-cost, environmentally acceptable plant-based extracts that exhibit remarkable corrosion inhibition into the coating system will provide enhanced corrosion protection to facilitate elimination of the primer thus achieving the desired single coat system. Luna will demonstrate the required performance properties of the coating system through the appropriate standardized military tests and in direct comparison to existing military specified products. Particular emphasis will be given to the dielectric properties and corrosion performance of the coating. Substantial cost and performance benefits with concomitant decreased environmental impact will be realized from the novel high performance system formulated to conform to existing logistical and operational requirements.

Title:Very Low Volatile Organic Compound (VOC) Spray Application Process for Iron Filled Elastomeric (IFE) Coatings
Abstract:This Small Business Innovation Research Phase 1 project will demonstrate the feasibility of a new method for spraying high viscosity IFE MagRAM coatings. This new method of forming sprays uses very little VOC solvents (estimated to be 5% by weight or less), and has two distinguishing features: (1) The application of effervescent atomization for producing droplets independent of the fluid viscosity, and (2) a perforated aerator tube insert to control both the Sauter mean diameter (SMD, or D32) and the distribution of drop sizes. These features allow for the reduction (elimination in certain applications) of VOC carrier liquids that are required with current conventional spray nozzles. The three key tasks of the Phase I project are: (1) to design and fabricate an effervescent atomizer to spray solids filled polymeric liquids with viscosities ranging up to 120 KU, (2) to evaluate the effervescent atomizer with coatings having a range of VOCs to assure that acceptable drop size and distribution performance is achieved with low concentrations of VOCs, and (3) to evaluate the spray performance and coating characteristics at low VOC concentrations. The anticipated primary result of the Phase I project is the demonstration of successfully spraying high viscosity coatings using effervescent atomization.

Title:Quick Cure Long-Shelf-Life Liquid Shim
Abstract:The Navy and the Air Force currently use epoxy liquid shim materials for aircraft assembly. The two-part epoxy is mixed just prior to the application on airframe components during assembly. However this method is time consuming as excessive labor is required to support mixing, application and cleanup of the excess liquid shim material. This particular process has historically been a schedule driver in the F/A-18 E/F as two part liquid shim materials typically require eight hours or more prior to being able to perform the next assembly process. With the aggressive production rates proposed for the JSF program, optimizing manufacturing throughput is of paramount concern, which means reworking liquid shim practices. In support of this, the Navy is looking for innovative material approaches creating a quick cure (less than two hours), long working life (greater than one hour), and a room temperature shelf life exceeding one year. New shim materials should also remove the liquid shim process from the critical assembly path. Under the proposed program METSS will evaluate single-component anaerobic-curing liquid shim compositions that will eliminate the need for mixing components, provide the required working time for parts assembly, and fully cure within two hours or less. The proposed technology can be rapidly commercialized, thereby offering the Navy potential for a near-term solution to this critical production problem.

Title:Rapid-Cure Liquid Shim
Abstract:The U.S. DoD and several of our allies have designed and developed an advanced military fighter aircraft, the Joint Strike Fighter (JSF). During assembly, a liquid shim epoxy paste is applied before joints are mechanically fastened to make the joined surfaces fit tightly, thereby strengthening the joints and making them more durable. The current liquid shims provide excellent physical properties (particularly adhesive and compressive strength) but typically require 24 hours to develop a suitable handling strength and up to 5-7 days for full cure at ambient temperature. Unfortunately, this long cure time results in a bottleneck for JSF manufacture. To remove the bottleneck, the JSF program requires a new liquid shim material that maintains the excellent properties of the current materials but cures in less than two hours. TDA Research, Inc. (TDA) proposes to adapt our novel epoxy curatives to develop a high-strength, rapid-cure liquid shim. In this project, we will demonstrate feasibility by preparing curatives, formulating them into rapid curing epoxy liquid shim pastes, and testing the shims' mechanical properties in accordance with Aerospace Material Specification 3726.

Title:Multi-Sensor Terrain Fusion
Abstract:The Navy is seeking improved capabilities to generate automatically elevation data products and have updatable and retrievable output via an automated advanced tactical terrain database system, supporting the Tomahawk Cruise Missile Program. The envisioned end-to-end solution must be able to process, manage, and/or fuse a variety of inputs, and these include multi-source imagery as well as existing, new, and non-standard elevation data. Named OmniDEM, we propose the innovative research and development of this new system accordingly. Specifically, highly accurate and robust digital elevation matrices (DEMs) are required to generate reference maps for the Precision Terrain Aided Navigation system. Of prime importance herein are: - A capability to detect change from multiple coincident DEMs; - A capability to determine if additional imagery (e.g., tactical) or data (e.g., updated control) will improve DEM(s) created previously; - A capability to combine or "fuse" surfaces from multiple DEMs; - A method for registering and validating source data; and - Heavy emphasis on leveraging and integrating existing capabilities from GOTS and COTS packages. DEMs are critical for missile navigation. In addition, the commercial and defense mapping marketplaces are demanding solutions of this type as well, which suggests an eventual commercial solution should do well.

Title:Multi-Sensor Terrain Fusion
Abstract:TSC will develop rigorous mathematical techniques to combine digital terrain elevation data from diverse multi-sensor sources to automatically generate a composite Digital Elevation Map (DEM). Sensor sources to be included for Phase I algorithm development and evaluation include existing DEMs, stereo photogrammetry, LIDAR, IFSAR, and stereo SAR. Quality metrics and error models will be developed for input to advanced regridding techniques which are now being used for IFSAR ground processing. These techniques will be modified to fuse diverse sources of terrain height measurements into an optimal composite DEM. TSC will also investigate co-kriging and novel belief propagation techniques, and investigate methods to detect and remove systematic errors, including tilts, shifts and biases which plague many sensor data sources. TSC will then design a preliminary full-scale software architecture that is compatible with both Navy and commercial operations. During Phase I, TSC will utilize GFE or in-house multi-sensor terrain data including aerial photos, X/P-band IFSAR and UHF/VHF stereo SAR to demonstrate the feasibility of these techniques. In Phase II, TSC will extend the most promising techniques to process data from additional sensors, of interest to the Navy, and will develop software algorithms that can be integrated with existing Navy and NIMA DEM generation tools.

Abstract:Vexcel is proposing to develop algorithms for digital elevation model fusion that utilize sensor models, sensor characteristics, and auxiliary platform information to improve the quality of fused digital elevation models. We will utilize our existing, non-sensor-specific DEM fusion prototype as a framework in which to prototype sensor-aware fusion capabilities. Our main thrust will be to develop quality metrics based on innate properties of the DEM production method, that can be used to guide DEM fusion by serving as an indicator of the relative quality of the DEM sources at a post. Our focus of study during the Phase 1 shall be the derivation of quality information for SAR stereo and interferometric SAR. We shall also study, as time permits, the derivation of quality metrics for the newer pushbroom optical sensors, such as Ikonos and Quickbird, which have more complicated sensor models than the traditionally used frame-based airborne EO cameras.

Title:Optimized and Rapid Employment of Loitering Weapons in Response to Fires
Abstract:ALPHATECH proposes to develop a tool addressing the unique planning needs of the tactical Tomahawk weapon system. Using an innovative combination of optimization techniques, this tool will generate cruise missile strike plans - missile trajectories and target coverage schedules - and generate new plans in response to in-flight retargeting needs. We will accomplish this by formulating the flight path construction problem as an approximate dynamic program, incrementally building missile trajectories. The use of a single, global optimization will produce synchronized strike plans which provide maximal target coverage - coverage which is shared across the set of missiles. This initial strike plan will include (1) missile routes, and (2) target feasibility schedules which describe (for each missile) those targets to which a missile may be diverted, and the associated timing constraints. From this plan foundation, we will develop weapon assignment algorithms that optimize the allocation of missiles to targets following a time-critical call for fire, or other retargeting event. Upon the solution of this weapon-target pairing sub-problem, we will re-optimize remaining missile trajectories to reallocate our coverage of any outstanding targets. Implementation of this methodology will provide strike planners with a robust planning and re-planning tool for the tactical Tomahawk weapon system.

Title:Real Time, Neurodynamic Programming Optimization For the Planning of Multi-Missile/Multi-Target Loiter Patterns
Abstract:In support of the Navy's Tactical Tomahawk efforts, a tool is to be designed which will generate optimal missile loiter plans, expediently and autonomously, for examination and utilization by field commanders and operators. The plans will incorporate any known constraints such as no-fly zones, communication coverage zones and mandatory targets as well as preferences such as minimizing time-to-targets, GPS coverage zones and loiter time. The Phase I task will employ simulation and classic Dynamic Programming (DP) to solve a simplified version of the general loiter problem, restricting the number of missiles, targets and constraints. Phase II will build directly on the approach developed and validated in Phase I, employing a Neurodynamic Programming (NDP)/Mixed Integer Linear Programming (MILP) algorithm to allow for generalized scenarios involving multiple missiles and targets and providing a convenient and computationally realizable solution. The resulting loiter plans could be displayed on a geo-spatial map with color-coding representing good-better-best preferred loiter patterns. The field commander/user could then be provided with an interactive device that would allow for easy adjustment of these patterns for constraints that are not known in time to be accounted for during the automated process or which are not formulated in the NDP/MILP algorithm.

Title:Fiberoptic Component Failure Prediction System
Abstract:We propose to develop a sensing system to monitor continuously the health status of aircraft critical mechanical components, including the software necessary for failure diagnosis, and prognosis of the components' remaining life. In order to achieve a low cost, rugged and reliable system, fiberoptic sensors embedded on the critical components are proposed. The fiberoptic solution meets the stated requirements of small size and weight, and particularly extreme reliability because of freedom from electromagnetic interference. The sensors are passive, require no electrical power and are affixed to the exterior of the mechanical components, thus creating negligible interference to the surrounding equipment. The fiberoptic sensors monitor continuously vibration and temperature, and the collected data are then sent to a processing unit on the aircraft that does the diagnosis and the prognosis. The small size of the fibers allows penetration of the bulkhead between the engine nacelle and the cockpit without any weakening of the structure. A unique feature of the proposed fiberoptic sensing system is the elimination of costly electronic switches, scalability, adaptation to a variety of aircraft, and the ability to mesh in directly with both, current copper avionic buses, and future fiberoptic versions..

Title:On-Board Real-Time Generator Component Failure Diagnostics
Abstract:The advent of prognostic health management (PHM) philosophies in condition-based maintenance (CBM) has clear benefits in cost savings and improved readiness. Generator failures in the E2C fleet have been a continuing problem, and this component would benefit from a CBM-PHM approach to maintenance. Since real-time data is needed for PHM models, fiber optic sensors could be used to eliminate the noise associated with electrical sensors inside an electrical generator. Prime Research is working with a major US research university to develop a novel PHM system which incorporates both fiber optic sensors and neural networks to prognosticate reliability and potential failures. The novel predictive system incorporates constantly updated data from design, manufacturing, quality control, and recent operational events into a model with a neural network component that can be `trained' to adjust to current events in any particular generator, and feed that data back into a fleetwide database to immediately update the prediction system of the entire inventory. The proposed Phase I program will demonstrate the feasibility of incorporating fiber optic sensor data into a PHM system for E2C generators, drastically improving remaining life predictions.

To define these requirements, Lakota will examine the services and attributes of current military and commercial middleware products, enterprise and Internet services currently in use within the commercial sector, as well as the design of various NCW applications currently deployed or in development for use aboard the E-2C aircraft.

Title:Global Information Grid (GIG)-Enabling Middleware (MW) Portals
Abstract:To allow affordable technology infusion into the E-2C a GIG middleware portal is required to adapt information semantic meaning and syntactical structure across information producers and consumers. The portal must interface to both commercial and militarized middleware products. Once established, the portal will be used to rapidly increasing operational capability and Fleet deliveries into an E-2C Global Information Grid (GIG)-enabled architecture.Our approach to this problem will provide the ability for new applications to automatically identify and receive the GIG-wide data that they require, to exchange the data that they produce to the rest of the GIG, and be portable to any hardware or operating system, using an innovated application based commercial Web Services, Global Grid Forum and Semantic Web technologies, and the GIG and Joint Battlespace Infosphere (JBI) initiatives within the services. Our proposed research and development effort focuses on solving the root of the problem - exchanging information that is semantically defined different, and structurally incompatible. For the Middleware Portal to be affective, two applications must be able to exchange information about "target tracks", where one calls it a "contact" and the other a "track", where one is a Java object and the other a XML structure.

Title:Communication Link Enhanced GPS/MEMS IMU Navigation System
Abstract:The objective of this SBIR Phase I project is to investigate and demonstrate the feasibility of a Communication Link Enhanced GPS/MEMS IMU Navigation System for low cost and precision guidance for military and commercial platforms, which are currently envisioned as solely relying on GPS for geopositioning. Since GPS signals are transmitted by GPS satellites operating at well-known frequencies with well-defined modulation characteristics and low signal-to-noise ratios, the possibility of enemy Electronic Counter Measures (ECM) attempting to deny reception of GPS satellite signals could be a potential problem for precision guidance. Low cost, miniaturized, reliable MEMS (MicroElectronicMechanicalSystem) inertial sensors and reduced size, weight, and cost communication link (such as Link-16) terminals offer an attractive opportunity to complement those GPS-reliant capabilities to provide full-range navigation information for precision guidance. In this Phase I, an innovative architecture, algorithms, and software to integrate the information from a communication link terminal, GPS chipset, and a MEMS IMU, are developed, analyzed, simulated, and evaluated to demonstrate and quantify the benefit of the proposed approach and algorithms.

Title:Integrated Communication Link and Global Positioning System (GPS) for Enhanced, Robust Position Information
Abstract:Air platform and weapon navigation systems encounter situations where GPS signal reception is deteriorated, making the position and time information less reliable or unavailable. In the event of jamming, GPS can even be totally denied under some conditions which prohibits access to precision positioning data for navigation, guidance or targeting. Future air platforms and weapons will carry next generation communications links designed to provide sensor-to-platform-to-weapon connectivity. The objective of this effort is to develop and demonstrate the ability to augment the GPS-derived navigation solution through "Network-Assistance" from the communication link to enhance the precision and robustness of the positioning information. Under this Phase I effort we will develop a system design for a GPS Network-Assisted Positioning (GPS-NAP) software application that can be transitioned into the Joint Tactical Radio System (JTRS). This will provide precise network time and TDOA observations to an integrated GPS/inertial Kalman Filter for enhanced, robust, position information. We will also investigate alternative JTRS waveforms which could be used for this purpose. Under Phase II, the GPS-NAP test-bed will be used to demonstrate the improved performance of the GPS-NAP solution using a JTRS test-bed, a SAASM GPS and an inertial navigation system to generate an integrated positioning solution.

Title:Miniature Low-Cost Bandwidth Efficient Advanced Modulation (BEAM) Transceiver for Small Uninhabited Aerial Vehicles (UAVs)
Abstract:In this Small Business Innovation Research Phase I project, Efficient Channel Coding (ECC) will validate Hi-BEAM (Highly Integrated Bandwidth Efficient Advanced Modulation), our novel, miniature, low power, and low-cost Bandwidth Efficient Advanced Modulation (BEAM) transceiver designed for integration in Small Uninhabited Aerial Vehicles (UAVs). In addition to exploiting Application Specific Integrated Circuit (ASIC) implementation methods, ECC's approach also exploits link power control. The current BEAM implementation in an ARC-210 radio uses multiple devices to enable the maximum flexibility. ECC asserts that most of the transceiver can be implemented in a custom Hi-BEAM ASIC. This level of integration has dramatic size and power consumption reductions. It is expected that Hi-BEAM ASIC will consume less than 2W of DC power. Thus, with the Hi-BEAM ASIC, the overall Hi-BEAM transceiver can be implemented in a small form factor (less than 50 in2), allowing for flexibility in mounting and integration with the small UA. ECC estimates the Hi-BEAM transceiver will use less than 25 watts of DC power while transmitting at 10 watts. The products developed under this project have a wide range of applications in UAV networks, and low-cost satellite terminals for a range of monitoring, tracking, and control applications.

Title:Miniature Low-Cost Bandwidth Efficient Advanced Modulation (BEAM) Transceiver for Small Uninhabited Aerial Vehicles (UAVs)
Abstract:Recent advancements in modulation and coding have produced waveforms that are not only both power and bandwidth efficient, but are also well suited for operation with small, highly efficient, non-linear power amplifiers. These new techniques can significantly improve the current throughput of standard 25 KHz UHF channels, thereby enabling a single channel to simultaneously carry digital data, imagery, and control. One attractive application for this technology is to transmit, receive, and relay digital data and imagery to and from uninhabited aerial vehicles (UAV's). The bandwidth efficient advanced modulation (BEAM) developed by Rockwell Collins, has demonstrated 100 Kbps throughput over a standard UHF 25-KHz channel. This program will be to design a miniature low-cost UHF transceiver suitable for use on a UAV that uses the BEAM waveform to efficiently transmit, receive, and relay digital data and images.

Title:Miniature Low-Cost Bandwidth Efficient Advanced Modulation (BEAM) Transceiver for Small Uninhabited Aerial Vehicles (UAVs)
Abstract:Tessera proposes to repackage an existing BEAM radio in a miniature, lightweight form factor. Tessera would use state of the art advanced semiconductor packaging techniques developed by Tessera. A partner with an existing radio design would be selected and advanced 3D packaging technology would be applied to reduce the size and weight to approximately 20% of the existing radio while increasing the reliability and reducing cost. Tessera has contacted a BEAM radio maker about repackaging their existing radio. While an agreement has not been signed, both companies agree in principle on the benefit of such collaboration. The advantage to the Government would be to have a known working radio reduced in size, weight and cost with minimum schedule and minimum risk. Tessera proposes to analyze the radio and partition the functional sections such that miniaturized modules can be designed for each section. The modules will be combined to form the working radio. Tessera proposes to perform the mechanical, thermal, and electrical analysis on the modules. Phase I will result in a design, analysis and report on work completed. Should the Phase I option be granted, the additional funding would be used to complete the detailed design of integrated passive components.

Abstract:Advanced Technologies Group, Inc. proposes a Solid-state, Lightweight, Active-balance-system, Powered-by-light, (SLAP). The SLAP balancer will reduce or eliminate drive shaft vibrations caused by rotational dynamics of the Joint Strike Fighter (JSF) lift fan drive shaft. Reduced shaft vibration will prevent drive shaft maintenance and improve support bearing life while reducing lift fan clutch wear. The innovative SLAP will not produce Electromagnetic interference, has low power consumption and is capable of millisecond response time. During phase I of this effort, Advanced Technologies Group, (ATG) will demonstrate the concept feasibility by performing bench-top rotational dynamics testing. Several applications have been identified for the new technology including commercial aircraft utilizing variable pitch propellers.

Title:Active Balancing for Lift Fan Drive Shaft
Abstract:The F-35 VSTOL configuration includes a lift fan driven by a long, slender hollow shaft that operates at high speeds. The shaft spins whenever the aircraft's engine runs, and transmits considerable horsepower when the lift fan is activated. In addition to being a key element in the aircraft's drive train, shaft maintenance will require engine removal. A device that observes and automatically adjusts imbalance in this shaft to eliminate its vibration would result in significant O&M savings. To address this need, an on-the-fly, self-adjusting balancing device is proposed that utilizes measured vibration to position shaft-mounted balancing disks to minimize shaft imbalance. This active balancing system will reduce or eliminate drive shaft vibrations caused by rotational dynamics to preclude undue maintenance of shaft system components. Based on influence coefficient (IC) methods, feasibility of the rotating balance disk concept will be demonstrated in Phase I by experiment. A system will be designed to perform multiplane balancing on a spinning shaft by properly positioning shaft-mounted adjustable weights. A test rig will be built to demonstrate the system in a single balance plane, and initial on-board mechanical and electronic hardware capable of withstanding the centrifugal loads without contributing to imbalance will be implemented. Performance of a single-plane balance on the test rig will demonstrate feasibility of the proposed approach.

Title:Active Balancing for Lift Fan Drive Shaft
Abstract:This Phase I SBIR Project will develop an Advanced Unbalance Control (AUC) system based on active magnetic bearing (AMB) technology and advanced feedforward control algorithms. The AUC system will offer at least an order of magnitude increase in both response speed and unbalance response reduction as compared to the best available mechanical unbalance cancellation methods. This will be accomplished by developing several key technologies: 1) high specific force AMB actuators; 2) advanced feed-forward controllers; and 3) an optimization procedure to ensure maximum effectiveness of the system in this and other applications. The AUC system will include both the method and hardware for reducing/eliminating unbalance response in many applications. This will be accomplished by using AMB technology in parallel with the current support bearings on the transmission shaft. The AMB will be utilized only as an actuator to apply rotating forces to the shaft for active unbalance force cancellation. The current configuration of support bearings remains the same. A complete test rig design, including design and analysis of the new actuators, and rotordynamics analysis, will be completed in Phase I. The Phase I Option will involve construction and testing of a laboratory scaled version of the F-35 lift fan drive shaft.

Title:High-Temperature Lubricant
Abstract:The Short Take-Off Vertical Landing (STOVL) version of Joint Strike Fighter (JSF) employs a unique propulsion system utilizing a three bearing swivel duct (3BSD) to direct the thrust of the engine exhaust. The 3BSD operates at high temperatures and incorporates large moving parts. The life cycle of the 3BSD depends directly upon the reliability of the lubricant used in the mechanical components. This lubricant will greatly affect how well the 3BSD will be able to perform during operation. The 3BSD requires a lubricant that can endure extreme temperatures and remain chemically stable with no performance degradation for the life of the three-bearing swivel duct, approximately 4,000 hours. The lubricant must also allow easy movement of the 3BSD throughout its full temperature operating range of roughly -40F to +625F. Current lubricants being considered for use in the 3BSD mechanical components can not maintain viscosity throughout the entire range of operation. Under the proposed SBIR program, METSS will develop an advanced lubricant capable of maintaining its properties throughout the wide range of operating temperatures through which the 3BSD is required to operate, thus lengthening the life of the 3BSD and its mechanical components significantly. To meet the performance requirements, METSS will focus on combining thermo-oxidatively stable lubricant basestocks, high temperature thickeners, solid lubricants and other necessary additives to develop a suitable formulation. This proposal clearly defines the tiered testing approach needed to identify the best candidates for subsequent testing and optimization in a subsequent Phase II effort.

Title: "Development of a 4000 Hour Bearing for the F-35B Three Bearing Swivel Duct"
Abstract:This proposal by Powdermet is offered in tandem with a separate proposal by a Wedeven Associates, Powdermet and DuPont Team targeted at developing a lubricated bearing system, incorporating improvements in the friction and wear material as well as the grease. The Tandem Wedeven primed proposal will evaluate improvements to the system including grease improvements, modifications to the surface of the bearing ball and race surfaces and with substitutions in the bearing and race materials. This Phase I SBIR proposal is focused on developing corrosion resistant nickel based thermal spray hardfacing of the bearing ball and race materials, including developing Powdermet nickel coated hardfacing powders, and a High Velocity Oxygen Fuel (HVOF) thermal spray process for depositing the coatings. The anticipated results of this program will be demonstrating improved wear life of the lubricated bearing system using a corrosion resistant nickel/titanium nitride or nickel/silicon nitride thermal spray material that has demonstrated very low wear and friction in other high temperature lubricated / lubrication loss applications being evaluated. The proposal also offers modification to the system including chrome addition to the nickel matrix for increased hardness and corrosion resistance, and solid lubricants to extend life especially the wear after grease lubricant loss.

Title:Ceramic Composite Lift Fan Clutch Plates with Improved Tribological Behavior
Abstract:The STOVL version of the Joint Strike Fighter utilizes a clutch to engage the lift fan. The clutch plates must dissipate large amounts of frictional energy introduced at a very high rate during engagement. Current carbon/carbon clutch plate materials do not possess the desired range of static and dynamic friction coefficients, and require more frequent servicing than other lift fan clutch components. The utilization of a ceramic-carbon hybrid matrix, where the ceramic is selected for improved heat capacity and reduced wear and the carbon constituent is optimized for thermal conductivity utilizes the strengths of all of the constituent materials. The hybrid ceramic-carbon matrix composite is anticipated to have a higher heat capacity, higher thermal conductivity, and result in a lower wear rate and more stable friction coefficient as compared to current materials. Both silicon carbide and boron carbide hybrid matrix composites will be fabricated and their mechanical, thermal, and high energy tribological behavior will be evaluated with respect to the requirements of the JSF lift fan clutch.

Title:Durable, Low-Cost, SiC-Based Ceramic Matrix Composite Lift Fan Clutch Plate
Abstract:Starfire Systems, a developer and supplier of silicon carbide (SiC) pre-ceramic polymer technology, and Goodrich Corporation, a recognized leader in the development and manufacture of friction materials and ceramic composites, will leverage the results of recent ceramic matrix composite (CMC) friction material development programs to support the development of a low cost SiC based CMC friction material for the JSF lift fan clutch plate. The program goal is to develop an SiC clutch plate capable of 4500 engagements (3X improvement) in the JSF lift fan application. The team will leverage experience from aircraft (CCAB) and auto racing programs (Formula 1) to select a minimum of three candidate SiC CMC friction couples for feasibility testing on a screening dynamometer for direct comparison to a carbon-carbon baseline. A base set of CMC friction formulas including modified carbon-carbon, fabric and felt preforms will be evaluated. The SiC matrix will be tailored to achieve maximum durability through variations in processing conditions and the addition of stabilizing elements such as zirconium. To support broader commercialization by accelerating the prototyping process, the team will review historical CMC friction data to create a methodology for rapidly selecting friction material formulas for any generic friction application.

Abstract:The objective of this proposal is to develop a simulation tool capable of accurate predictions of the complex mixing process in gas turbine engine combustors, applicable to complex geometry, multi-physics problems, and combustion in lean and high FAR regions. Because of the importance of the mixing process, the simulation tool will be based on the large-eddy simulation technique. The code will be based on our unstructured LES code CDP, which is a highly specialized and optimized for LES and uses appropriate LES filters and numerical methods. A state-of-the-art combustion model using detailed chemical kinetics for JP-8 fuel will be developed and employed to describe turbulence/chemistry interactions. It is also proposed here to use the simulation tool to gain a better understanding of the interaction of combustion and the mixing process and to enable better control of the burnout of high FAR regions.

Title:Advanced CFD Software for Improving Durability of Turbine Inlet Guide Vanes
Abstract:In high F/A military gas turbine combustors such as JSF, localized pockets of carbon monoxide (and perhaps hydrogen) can exit the combustor, causing severe cooling challenges for designers of turbine inlet guide vanes. Instead of cooling the vane, cooling air can actually interact with the hotpath flow to release heat near the vane surface, resulting in catastrophic damage. In this SBIR, we propose to develop innovative 3D CFD software that accurately predicts the effects of heat release and heat transfer into the vane. Current CFD codes are not capable of such analysis. Our software will utilize combustion Large Eddy Simulation (LES) and Reynolds Averaged Navier Stokes (RANS) methods. In Phase I, the overall feasibility of this approach will be demonstrated. Initial work will focus on implementing/validating near wall turbulence models that accurately predict boundary layers in LES calculations without fully resolving the boundary layer. We will then analyze flow past a single vane that mimics the physics seen in the actual JSF application. Our selected subcontractor, University of Cincinnati, will provide test data from a cooled generic vane under fuel-rich conditions. CFD predictions will be compared to measurements of surface temperature and heat flux at the vane surface to assess the analysis capability. In Phase II, model improvements identified in Phase I will be implemented and validated, followed by analysis of JSF vanes and potential design improvements.

Title:Helicopter Operations Aircrew/Crew Chief Trainer
Abstract:Helicopter crew chiefs primarily receive advanced skills training during in-flight training missions. This training methodology is expensive and potentially dangerous. A simulator designed, developed, and produced based on derived skill-based requirements employing innovative virtual technology with tactile interactions would be an excellent training tool. The question remains: Can such a simulator that enables maximum flexibility for varied task training be affordably produced? Helicopter crew chiefs throughout the military perform varied but similar tasks. These tasks principally consist of door gunner engagements, search and rescue (SAR), vertical replenishment (VERTREP), interactions with flight and ground/sea crews, hover control, swimmer deployment/recovery, hoist operations, night searches, mine/Doppler operations, and emergency procedures. The proposed SBIR study will analyze the tasks of the H-60 crew chief, develop training requirements based on those tasks, and present trade-off analysis of technologies that meet those training requirements in a simulator environment. At the completion of Phase I, Binghamton Simulator Company will provide recommendations on the feasibility of developing affordable and effective crew chief training in a simulation environment.

Title:Helicopter Operations Aircrew/Crew Chief Trainer
Abstract:The effectiveness and safety of complex, multi-role helicopter platforms such as the Pave Hawk and Seahawk require that the cabin crew interact seamlessly with the flight crew and a dynamic external environment. Due to physical constraints and fidelity limitations, however, current simulation designs fail to accommodate a wide range of training. The proposal herein introduces a novel and elegant approach to this challenge by employing three proven technologies - live video capture, real-time video editing (blue screen imaging), and virtual environment simulation - thus offering a quantum jump in training realism and capability. Video from the trainee's perspective is sent to a processor that preserves near-space (cabin environment) pixels and makes transparent the far-space (out-the-cabin) pixels using blue screen imaging techniques. This bitmap is overlaid on a virtual environment, and sent to the trainee's helmet mounted display. Thus the user directly views the physical cabin environment, while the simulated outside world serves as a backdrop. Using this technique, a litter that is physically pushed out and lowered from the cabin can be replaced by a virtual surrogate, which proceeds to be lowered into the simulated environment. A motion platform, cabin mock-up, and a speech analyzer comprise the remainder of the trainer.

Title:VOC-Free, Waterborne Flexible Primers for Aircraft Maintenance
Abstract:A VOC-free, non-chromated flexible primer is proposed for protecting highly flexed aluminum aircraft components in the corrosive marine environment. Aqueous dispersions of elastomeric resins stabilized with novel modifiers and pigmented with non-toxic anticorrosive agents will be used to formulate primers with excellent adhesion to aircraft structures, low temperature flexibility and exceptional corrosion inhibition. The proposed research seeks to further develop and refine a novel coating binder technology developed in our laboratory for a VOC-free, non-chromate flexible primer system that meets the current TT-P-2760 specification. The proposed anticorrosion formulations, although waterborne, will readily form low permeability films and adhere strongly without the need for pre-coat priming. The new flexible primers will be designed to allow application with conventional paint spraying equipment. The development of new multi-function polymeric additives should significantly improve the formulation stability and reduce water sensitivity of the resulting primer coatings. The VOC-free coatings will be tested against conventional solventborne flexible primers for adhesion and corrosion inhibition in accordance with TT-P-2760. The ability to form adherent, highly flexible and durable barrier coatings over non-ferrous metals without the need for volatile organic solvent dilution would represent a significant advancement in corrosion engineering and aerospace maintenance technology.

Title:Development of a Novel Flexible VOC-Free Chromate-Free Primer for Navy Aircraft
Abstract:The military currently uses a flexible primer (TT-P-2760) as part of their coating system for many types of aircraft. This primer prevents film cracking and subsequent corrosion, especially at high flexing components and fastener patterns. However, it contains organic solvents (VOCs) and chromate corrosion inhibitors that are now restricted for environmental reasons. Consequently, the Navy is seeking a replacement primer that meets or exceeds the existing primer specifications, but that does not contain chromium or organic solvents. The novel coating system proposed here is comprised primarily of three low-cost, commercially available ingredients selected to provide low-temperature flexibility, excellent substrate and topcoat bonding, and the required mechanical strength. The formulation also includes corrosion inhibitors and minor functional additives. Chromate inhibitors will be replaced by a package of inorganic and organic inhibitors that demonstrate comparable corrosion inhibition of Al 2024-T3 and Al 7075-T6. Inhibitor leaching will be enabled by elevated pH conditions to provide "inhibition-on-demand." In Phase I, primer formulations that exhibit the necessary flexural and corrosion resistant properties will be developed and characterized for flexibility, corrosion resistance, and mechanical properties. Phase II will involve refinement of the primer formulation to meet all relevant Military Specifications, and field-testing. (P-030580)

Title:Non-Chromated Flexible Aircraft Primer Containing Zero Volatile Organic Compounds (VOCs)
Abstract:A 100% solids, corrosion-inhibiting, flexible, and sprayable primer that is free of volatile organic compounds (VOCs) is proposed that will replace the current chromated primers currently in use by the Navy. This unique system differs from others on the market in that it does not require the addition of corrosion inhibitors to perform its task. The resin system itself is inherently corrosion-inhibiting, and onsite corrosion studies at Texas Research Institute Austin have shown excellent results in using these primers on steel and aluminum in a salt-fog chamber. The manufacturer of the base component has logged over 2000 hours of corrosion-free exposure on aluminum panels in a salt fog chamber. This new primer will be tested against federal specification TT-P-2760A to ensure that it meets the performance requirements of the Navy. TRI/Austin will be teaming with the manufacturer of the primer's base component as well as a respected marine coating manufacturer for marketplace transition. A new corrosion-inhibiting primer will have utility outside of naval applications in commercial marine and automobile applications.

Intevac's existing technology for IPD sensors meets the performance requirements for such applications. The proposed sensor optimizes packaging by integrating the high-voltage power supply and output amplification stages into a single compact and rugged sensor unit targeted for 532nm wavelength applications. Program tasks include (i) redesign of the sensor tube component to reduce its size while providing an 8mm diameter optical active area; (ii) integration of an appropriate high-voltage bias supply so that only 24VDC power is required to operate the sensor; and (iii) integration of an appropriate amplification circuit to provide a properly conditioned high-gain low-noise sensor output.

Title:8 mm Diameter Solid State Photodetector at 532 nm
Abstract:We propose to develop a high performance, solid state photodetector with 8 mm diameter. It will use a novel solid state microchannel plate incorporating a proprietary avalanche gain structure. In Phase I, the design concept will be validated experimentally to prove feasibility and scalability. The Phase II activity will build, demonstrate and deliver the photodetector and transimpedance amplifier in a module occupying less than 1 cubic inch. The module at 0 degrees C will simultaneously achieve single-photon sensitivity at 532 nm, 10 bits of dynamic range, GHz bandwidth & pulse-pair resolution, 100% (ungated) duty cycle, and less than fW/Hz^1/2 noise-equivalent power at 40 dB of detector current gain. A typical TIA provides another 20 to 40 dB of current gain at 5 pA/Hz^1/2 (0.5 fA/Hz^1/2 equivalent input noise). The system NEP at 74 degrees C, operating uncooled, is projected to be below 1 fW/Hz^1/2. The proposed solid state detector technology is low voltage, rugged, and cannot be blinded.

Title:Prognostic Health Assessment System for Aircraft Engine Nozzles
Abstract:Impact Technologies, in collaboration with Luna Innovations, proposes to develop and demonstrate a prognostic health assessment system for aircraft engine nozzles and their associated actuation components. Modern aircraft deployed in limited runway situations have specific requirements for Short Takeoff and Vertical Landing capability. The Joint Strike Fighter has an adjustable three-bearing swiveled nozzle at the back end of the engine to generate downward thrust and increasingly forward thrust in flight. The development includes the necessary sensing, incipient fault detection algorithms, fault classification techniques, and advanced prognostic, useful life remaining algorithms. Luna will provide the necessary high-temperature, robust sensing and some signal processing components, and Impact will apply feature-based diagnostics, suitable wear and fatigue failure mode progression algorithms, and advanced knowledge fusion within the nozzle actuation health assessment system. Moreover, Impact will implement its proven probabilistic fusion process to update useful remaining life predictions from the failure progression model with observable diagnostic indicators and material inspections. A verification plan with consideration to the JSF engine and nozzle actuation development and testing programs at Pratt & Whitney and Smiths will also be developed during this effort.

Title:Diagnostic and Health Monitoring Techniques for Engine Nozzle Actuation Hardware
Abstract:The proposed effort emphasizes a systematic process for adding diagnostic and prognostic coverage for monitoring the health of the JSF short takeoff/vertical landing (STOVL) engine exhaust nozzle hardware with the goal of improving reliability and aircraft availability. The process involves the identification of the most significant failures, trading off different prognostic techniques to achieve a cost-effective balance between the cost versus benefit gained, and then developing new sensors and tests and evaluating them in simulation, test stand, and actual flight conditions. The end product of this effort is not just a collection of new tests for early detection of failures in a few degraded components; it is a complete diagnostic and prognostic solution utilizing the sensors and capabilities that already exist to the greatest extent, while identifying new capabilities that can easily be embedded or provided in ground support equipment, to achieve maximum mission reliability within a reasonable cost. On this effort, Qualtech Systems, Inc. will collaborate with HR Textron for design and test data for actuators, for simulation and test-stand facilities, and for commercialization efforts in Phase III. Consultation and cooperation with Pratt & Whitney are also anticipated, particularly in Phases II and III.

Title:Dual-Band Electro-Optic (EO)/Infrared (IR) Multifunctional Pod Windows
Abstract:Increasingly missions are turning to EO/IR operation requiring windows with large spectral bandpass. This large bandpass coupled with the size of the required window substrates has necessarily limited the choice of materials. Calcium Flouride is generally chosen, however it has the undesirable property that it tends to scratch quite easily. In this proposal we will discuss a proprietary method of manufacturing large POD windows made from Sapphire Substrates which are much harder while simultaneously offering equivalent or better optical performance. The result of the research discussed here will be the routine production of far superior windows leading to much longer field lifetimes and lower program cost.

Title:Dual-Band Electro-Optic (EO)/Infrared (IR) Multifunctional Pod Windows
Abstract:Aluminum Oxide (sapphire) windows are a critical element Electro Optical (EO) and infrared (IR) imaging systems. As the demand for an increase in the performance of these optical systems rises, so must the quality of the sapphire windows. One of the most technically challenging aspects of producing high quality sapphire optics is achieving the required surface figure while maintaining a stress free optical surface with good surface finish (or micro-roughness). The desired surface figure error is now < 0.03 waves rms as tested at 632.8 nm for a 22" diagonal sapphire window. Even with extremely skilled opticians, the conventional fabrication process to achieve this surface figure on sapphire optics while maintaining tight wedge specifications and high surface quality can be very slow and costly with the quality of the results being unpredictable. The purpose of the research proposed here is to develop a complete fabrication process (from blank to final shape) that will produce high quality sapphire windows by incorporating magnetorheological finishing (MRF) as the final step of the process. The research will show that by combining the MRF process with the proper CNC grinding and pre-polishing processes, low-cost, high-quality sapphire windows can be deterministically fabricated to repeatedly meet the desired specifications. Phase I of the research will include demonstrating the ability of the deterministic MRF process to meet and exceed the surface figure requirement of 0.03 waves rms. Furthermore, MRF may be used to optimize transmitted wavefront of the window, thereby correcting for both surface and substrate errors. The surface quality (micro-roughness and subsurface damage) from different grinding and pre-polishing processes performed by Saint Gobain Abrasives will also be evaluated after final finishing with MRF. Phase II will optimize and scale the fabrication process to produce a 22" diagonal sapphire window to meet the desired specifications.

Title:An Integrated Antenna Set for Software Radios
Abstract:Joint Tactical Radio System (JTRS) is a software radio capable of tuning from 2MHz to 2000MHz. A wideband antenna or a set of antennas are needed to support operation across the entire frequency spectrum of JTRS. To meet this need, Applied EM is proposing an innovative conformal design, which addresses the issues of ultra wide bandwidth, and conformality. The proposed design employs a novel material design to increase the bandwidth of conformal antennas. A set of two antennas, one for the HF band (2-20MHz) and the other for the VHF/UHF bands and above (20-2000MHz) is proposed. For this adaptation, traditional broadband antennas will be optimized using emerging materials and scaling for a design which satisfies the required size restrictions and satisfies gain, pattern, and return loss requirements. Under the proposed effort, we will develop engineering prototype antennas and validate the design through measurements. Development of these ultra wideband antenna designs will provide for robust antenna systems capable of providing interface not only to JTRS, but also to a wide variety of broadband communication equipment.

Title:Reconfigurable Nested Plasma Antennas and Reconfigurable Stacked Plasma Antenna Arrays as Wideband Apertures and Uses in the JTRS
Abstract:In this Phase I SBIR project for the US Navy integrated antenna set for software radios, Haleakala Research and Development, Inc., proposes to analyze, perform experiments on, and build prototypes of a set of wideband apertures that covers 2 to 2000 MHz such that these airworthy apertures can be used in conjunction with the JTRS with applicability. This problem is worth working on because current airborne and ground vehicular antennas do not provide adequate gain to the links provided by the JTRS. Plasma (ionized gas) conducts current like a metal and one can create an antenna from plasma. The advantage of the plasma is that it can be created on demand and one plasma antenna can be reconfigured in time or space to a variety of beam widths, bandwidths, directivities, and radiation patterns. Furthermore plasma antennas and plasma arrays can transmit through one another whereas metal antennas cannot. We will meet the technical challenge by theoretically predicting and experimentally building wideband plasma antennas In Phase II, Haleakala will implement the complete design package produced in Phase I. Our goal in Phase III is develop to provide a flexible single or multi-beam forming plasma antenna for both military and civilian use.

Title:An Integrated Ultra-Wideband Antenna for Software Radios
Abstract:Pharad proposes the design of low profile, conformal, efficient, ultra-wideband antenna platforms that can operate over the entire 2 MHz to 2 GHz frequency band. Such an antenna will be an integral part of the Joint Tactical Radio System. Our innovative approach to achieving such a large operating bandwidth encompasses two key aspects: (i) the implementation of a series of wideband printed diplexers that split this multi-decade bandwidth into more manageable frequency blocks and (ii) our selection of optimal radiating elements, namely Aperture Stacked Patches (ASPs) for frequencies greater than 250 MHz and for the lower frequency range, the use of either existing low frequency aircraft antennas or our proposed novel printed multi-layered spiral antenna. Our proposed ultra-wideband antenna incorporates all the salient attributes of printed circuit technology (low profile, lightweight and low cost). Another feature of our antenna platform is the relative ease with which it can be upgraded to operate at frequencies well beyond 2 GHz, as a result of the low component count. Since our ultra-wideband antenna system is based upon printed circuit technology, we will also conduct material, thermal, vibration, and reliability analyses to ensure it can tolerate the strenuous environmental conditions encountered on an aircraft.

Title:Sensemaking in the Battlespace: An Innovative Human-System Paradigm for Combat Systems
Abstract:The Navy is taking revolutionary actions to redesign itself to take advantage of developments in information technology, such as automated systems. This project will explore the feasibility of developing a tool for enhancing operators' situation assessment in an environment characterized by increased use of automation and reduced manning. Our Phase I effort will provide the functional architecture and initial proof of concept for the design of a management tool that is based on the requirements for a human-machine team player paradigm and the methodology for enhancing operators' situation assessment. Utilizing the Data/Frame model of sensemaking, Klein Associates will design a methodology that formalizes the process by which operators make sense of situations and how they develop situation awareness over time in an SMC environment. Once we have achieved those objectives, we will be ready to iteratively design, develop, and test an interface prototype using our decision-centered design strategy. The outcomes of this project will serve as an exemplar of how to design combat systems on future Navy ships.

Title:Multi-Axis Fiber Optic Strain Sensor and High-Speed Multiplexing System.
Abstract:SPA proposes to develop a real-time vertical launch system environmental monitoring system (VLS-EMS). This open-architecture system will accommodate 48 fiber-Bragg-grating-based tri-axial accelerometers (8 optical channels with 6 accelerometers per channel) to monitor shock and vibration on VLS canisters at speeds of at least 5 kHz. The VLS-EMS also has the ability to expand to include additional sensors, including temperature and humidity sensors, to make it a more comprehensive monitoring system. The Phase I effort involves upgrading our current patented High Speed - Fiber Optic Interrogation System (HS-FOIS). The HS-FOIS already comprises of 8 optical channels that are capable of monitoring 20 sensors each at speeds up to 2 kHz. To increase the speed of the system to 5 kHz per channel, a new CMOS camera will be purchased, the data protocol will be changed from frame grabber to Firewire 800, and a 64-bit data bus will be procured. The other main objective of the Phase I effort involves developing a tri-axial accelerometer from our existing single axial accelerometer design. SPA will manufacture and test several prototype tri-axial accelerometers. The ultimate goal of the Phase I effort is to demonstrate the tri-axial accelerometer design on the newly upgraded, faster HS-FOIS.

Title:Wideband Digital Beamforming and Direction Finding
Abstract:Recent advances in Field Programmable Gate Arrays (FPGA's) and Digital Signal Processing (DSP) devices are providing a means for the development and fielding of wideband digital receiver suites for Electronic Support (ES). Digital processing of these signals can result in significant improvements in parameter measurements such as Direction of Arrival (DOA), frequency measurement, time of arrival and signal amplitude as well as improved envelope and modulation estimation. Use of advanced digital processing also allows for the implementation of modern interference cancellation algorithms to allow processing of today's high density signal environments containing many overlapping signals. The proposed research will study the feasibility and effectiveness of a novel wideband interference cancellation technique for separating overlapped signals. The technique is based on an extension of existing IFM techniques. It makes use of a series of co-variance matrices from which a set of eigenvectors can be found. These eigenvectors are used for signal detection, time up, frequency and angle of arrival measurements. These parameters are then used as components of typical pulse descriptor words that can be fed into existing pulse separation and association processors for further downstream processing. Use of FPGA and high speed DSP chips allows these algorithms to be implemented in real time and in a fieldable form factor and in fact, can be readily inserted into existing systems.

Title:Conformal X-Bank Seeker for Semiactivee Guided Projectile
Abstract:This SBIR Phase I proposal is for the development of a conformal X-band antenna for an interferometric semi-active seeker for a 5 inch projectile. A seeker design based on interferometry is proposed because conventional seekers are difficult to implement on projectiles where high g forces at launch and body shape constraints make gimbals and radomes impractical. Conventional conformal antenna accuracies are susceptible to degradation when the target is off-axis. Interferometry offers more consistent off-axis performance and less sensitivity to antenna variations. The interferometric seeker can be implemented on both spinning and non-spinning projectiles and imposes no timing or special antenna requirements on the illuminator. Interferometry allows a variety of configurations and projectile installation options. The objectives of the proposed effort are to evaluate alternative interferometric antenna configurations,select that with the best performance/cost benefit and to validate its predicted performance by constructing and testing a laboratory prototype. Several configurations are discussed and described including conformal "patch" arrays, waveguide and minimally sized nose cone installed forward looking arrays. A plan is proposed that results in a prototype seeker antenna. An option is proposed that validates interferometric accuracy in a static projectile configuration.

Title:Multiple-Beam Electron Gun for Radar Applications
Abstract:The objective of this program is to develop a multiple electron gun capable of high-repetition rate operation to be employed in high-power broadband multiple beam amplifiers for future radar and communications applications. The performance of these amplifiers depends critically on the quality of the electron beam produced by the electron gun, and thus, the proposed research program is structured to ensure the successful development of a key enabling technology. A particular emphasis of this program will be the design of the gun's beam modulation electrodes to be compatible with existing and planned pulsed power technology. A secondary emphasis will also be placed on the cathode current density to ensure long operational lifetime. State-of-the-art 3-D gun code, MICHELLE, and magnetic code, MAXWELL-3D, will be employed for the gun design in the Phase-I program. The resulting electron gun will be developed and tested in collaboration with our industrial partners during the Phase-II program.

The primary objective of this proposal is to demonstrate the feasibility of developing a Micro AUV Ready Chemical (MARCHEM) Analyzer. This device will be capable of performing real-time, rapid response measurements of trace chemicals in marine waters. This sensor will use specialized low-power, miniature, electro-fluidic and optical detection devices to accomplish the chemical analysis.

SubChem Systems is working closely with the Navy to ensure that the technologies meet service needs and will be adopted by end-users. Further, we are working with the manufacturers of AUVs to ensure a pathway to commercialization and marketing.

Abstract:The objective of this proposal is to demonstrate the feasibility of developing a compact, low power, autonomous, scalable, bottom-up profiling system for long-term (up to 6 months) deployments. This Miniaturized, Autononomous, Moored Profiler (Mini AMP) will contain a suite of environmental sensors, an integrated data control system, and a telemetry unit as a part of a modular, winch-driven profiling platform. The compact, hydrodynamic, low power design of the Mini AMP system will support a variety of long-term applications, where real-time, high vertical resolution physical and bio-optical data are required. The overall goal of this research will be to design a MINI AMP system that offers the consumer a high level of flexibility in sensing parameters, data telemetry and data control, while maintaining a high level of performance, reliability, accuracy, and ease of use thereby making the system inherently scalable. The prototype design to be developed in this Phase I research will be based on a multi-parameter sensor suite including an optical scattering detector, chlorophyll and colored DOM fluorometers, a spectral attenuation meter, a spectral irradiance sensor, and a CTD. The telemetry unit, an Iridium-based communication link, will provide bi-directional communications for profile scheduling and data retrieval capabilities from remote locations.

Title:Communication Links for Spatially Distributed ASW Sensor Systems
Abstract:The Navy intends to develop distributed fields of underwater sensors devoted primarily to ASW, but possibly having extensions to a variety of disparate applications, such as environmental sampling. These fields may include stationary nodes, mobile nodes, or combinations of the two. The two features common to all are the need to move data among the nodes of the field, and to autonomously reconfigure the (ASW) focus of the system to respond to an evolving threat situation. It is anticipated that the ability of an individual sensor to perform the mission will be extremely limited, thus necessitating cooperative interactions among multiple sensors, and information fusing across the field. This, in turn, suggests that the sensors may have to be physically close, implying that large numbers of sensors will be required. There are instances in which the requisite network connectivity can be accomplished with hard-wired links, but in the majority of cases, acoustic communications (acomms) will be the preferred method. Although the acoustic channel is in a medium that often does not support rapid data transfers without excessive transmitter power, or which limits signaling to very short ranges, in this instance the acomms channel appears well matched to the short range separation among sensors. The Navy has, over many years, investigated the utility of many types of sensors for ASW purposes, including passive and active sonar, magnetics, and optics, among others. The Navy has also investigated many techniques for signal and data processing and analysis. Most have shown value under some circumstances, but not in others. Probably the most reliable, certainly the least difficult to use, is passive acoustics. This is also an undetectable approach which advances consideration of covert operation of the network. The preferred approach, however, is to develop both nodes and networks capable of supporting a variety of sensor and processing types. The problem we wish to address with this proposal is the development of low cost sensor nodes, each providing modest ASW performance within a limited physical range, with reliance on the network to refine the performance. We will describe a system in which the nodes may contain a variety of sensor types, with the nodes linked together by robust, clandestine acoustic communications supporting directed response to potential targets, with network-wide data fusion and transmission to an end-user. We anticipate that some portion of the work will be classified.

Title:A New Computing Paradigm for Energy-Efficient Collaboration in Underwater Sensor Networks
Abstract:In this proposal, Intelligent Automation, Inc. (IAI) and its subtractor, Prof. Hairong Qi of the University of Tennessee at Knoxville, propose a novel mobile-agent-based computing paradigm for collaborative information exchange among distributed sensor nodes. Unlike the traditional client/server-based method, the proposed mobile-agent-based approach transfers the partially integrated results and executable code from one node to another and the processing can be done locally on the sensor nodes. The proposed approach consists of two levels: (1) mobile-agent-based computing for collaborative processing among multiple sensor nodes and (2) data processing and fusion at the local nodes. The proposed mobile-agent-based computing model provides a nice balance between energy efficiency and fault tolerance. It presents a framework for efficient usage of energy and bandwidth, scalable computing, reliable and fault-tolerant decision making, as well as supports intermediate results with progressive accuracy. The collaborative data processing and fusion algorithms use the information from multiple sensors. We develop both simulators to study the performance between the mobile-agent-based collaborative processing and the client/server-based centralized processing based on compression algorithms providing a compression ratio.

Title:Autonomous Underwater X-ray (AUXRAY)
Abstract:Nomadics proposes the development of an x-ray system for use underwater. The proposed sensor is similar to a raster or "flying spot" backscatter imager. These systems operate by scanning an x-ray beam across a surface and monitoring the backscattered energy. There are two significant challenges to this process, first the system has to operate in an incredibly attenuating environment; second, that environment scatters a large portion of the incident energy before it ever reaches the target. With these two design limitations, Nomadics' believes that the key to building a successful Autonomous Underwater X-Ray system (AUXRAY) is to have a large detector area for sensitivity and separation between the source and detector to reject signal from the transiting x-ray beam.

Title:Lobster Eye X-Ray Imaging Underwater Scatterometer
Abstract:The Office of Naval Research (ONR) needs an underwater x-ray imager/scatterometer system for high-quality imaging of mines and other objects buried in sediment, and to analyze the porosity and structure of the sediment itself. The system is to be based on backscattering x-ray technology and be mounted on small underwater vehicles, including remotely operated vehicles and autonomous underwater vehicles. Sonar detectors can sense underwater mines even in dark, opaque water, but cannot detect buried mines. To meet the Navy need, Physical Optics Corporation (POC) proposes to develop a new Lobster Eye X-Ray Imaging Underwater Scatterometer (LEXIUS) that enables focusing hard x-rays and discriminating mines from similar objects. Another advantage of LEXIUS is that it can collect vital information on buried mines in real time. The proposed LEXIUS images mines and other buried objects by means of Compton backscattering. It will operate in the x-ray energy range 40 to 60 keV, at a rate of at least thirty frames per second. LEXIUS provides enhancements in both resolution and signal-to-noise ratio due to the use of true focusing capabilities of POC's proprietary Lobster Eye x-ray optics.

Title:Anti-Torpedo Data Fusion and Optimization System (ATDOS)
Abstract:Daniel H. Wagner Associates, Inc. will develop an Anti-Torpedo Data Fusion and Optimization System (ATDOS) which will fuse all available data using multiple hypothesis association, Gaussian sum and non-Gaussian tracking, and Bayesian inferential reasoning techniques to produce a torpedo defense Tactical Picture (TP). Given this TP, ATDOS will optimize the utilization of all available anti-torpedo sensors, especially any active sensors, using non-Gaussian optimization algorithms. Although our initial focus will be on generating the torpedo defense TP and optimizing sensor utilization, in Phase III we may potentially optimize weapon employment as well. This use of advanced data fusion and optimization algorithms is critical for the success of an anti-torpedo system, since even the new passive and active sensors and their associated signal processing algorithms that are currently being developed will produce large numbers of both persistent false contacts (primarily from contacts on surface ships, although air and land targets will also be detected) and non-persistent false contacts. Thus it is critical to develop a sophisticated data fusion system that can process all of the available information concerning targets of interest, taking advantage of all of the detection and non-detection information produced by passive acoustic, active acoustic, and non-acoustic sensors.

It appears that LRT is a promising method of addressing the false alarm problem, but efforts to use LRT have been hampered by our inability to obtain accurate predictions of sensor performance, particularly probability of detection as a function of target state. Using an inaccurate prediction of sensor performance in the likelihood functions employed by LRT can provide misleading results and degrade the performance of LRT. Metron proposes to extend the state space of LRT to include a random variable that represents the prediction error in mean signal excess so that we can incorporate performance prediction into LRT in a way that accounts for the uncertainties in the predictions. This will allow us to improve its detection and false alarm rejection capabilities for multistatic active systems such as EER, IEER, and Distant Thunder. In doing this Metron will be assisted by Signal Systems Incorporated (SSC) who will help to develop the detection models used in this extension of LRT.

Title:Coherent Multi-Static Active Sonar LRT
Abstract:Multistatic sonar technologies are emerging as an important strategy for addressing passive ASW sonar-performance shortfalls. Multistatic operations can potentially improve ASW effectiveness in challenging shallow-water environments while allowing critical assets to remain acoustically covert or at a safe standoff distance. The Navy uses multistatic acoustic sensor systems with aircraft and surface ships, in a networked-centric ASW search and surveillance missions. Current incoherent systems suffer from high false alarm rates when operating in shallow water and potentially alert the target by using explosive sources. A method of reducing false alarms and not unnecessarily alerting our adversaries is needed. Coherent active sonar systems offer greater duty cycles, are not confused with weapons deployment when transmitting, and enable Doppler processing. The combination of higher duty cycles and controllable waveforms hold the potential for reducing false alarms. SSC and its teammate, Metron Inc., proposes to utilize Likelihood Ratio Tracking (LRT) to optimally combine multiple echoes, detect and track multiple targets using low signal to noise (SNR) threshold detections to form consistent target tracks over space and time. Extensions to LRT using Doppler information will be developed. This technique has been used successfully in incoherent multistatic active sonar systems and in passive sonar.

Title:Aerosol Mass Spectrometer for Aircraft Sampling using Time-of-Flight Mass Spectrometry
Abstract:Aerosol particles play an important role in visibility, acid deposition, climate, and human health, although large uncertainties remain in quantifying their impacts which depend on their chemical composition and atmospheric transformations. An innovative aerosol mass spectrometer has been recently designed to fill a critical need for size-resolved, quantitative chemical composition data on aerosol particles. An aircraft version of this instrument that meets the size, weight, ruggedness, and time resolution requirements for aircraft operation has been deployed aboard ONR's CIRPAS Twin Otter research aircraft. We propose to upgrade this instrument in order to improve detection sensitivity which is critical for aircraft measurements in clean environments. This includes hardware and software developments to improve autonomous aircraft operation. The ultimate goal is to incorporate a time of flight mass spectrometer which will dramatically improve the detection and characterization of specific chemical species, and will enable chemical composition measurements on an individual particle by particle basis.
