Title:High Strength Stress Corrosion Resistant Aluminum Casting Alloys
Abstract:The approach selected to address the development of High Strength Stress Corrosion Resistant Aluminum Casting Alloys is to use A201 and AA2139 as the base alloy and modify/optimize the composition use thermodynamic modeling . Reducing the susceptibility to hot-tearing will be achieved through the use incorporation of grain refiners such as dispersoid forming elements to control the dispersoid/dendrite precipitation characteristics and to improve fluidity. Appropriate precipitation, strength, and solidification simulations will be performed to support alloy design and production. Alloys will be produced and tested to determine the microstructures, mechanical properties, and resistance to stress-corrosion cracking. Results of this effort will be included in a thermodynamic database. The EFV water jet inlet housing or steering bucket will be produced using an alloy developed on this program.

Title:High Strength Cast Aluminum Alloys
Abstract:ORBITEC proposes to develop high strength cast aluminum alloys for use in Expeditionary Fighting Vehicle (EFV) structures. Using a new casting technique developed by MSOE, the cast alloys HPAC structures will achieve material properties similar to those of forged structures. The casting process is well suited to the fabrication of components from existing metallic alloys and also facilitates the use of new cast alloys, particle and fiber reinforcements to create metal matrix composites to tailor the mechanical properties of the materials. In addition, designers will have the ability to optimize the alloys composition and properties at different points within the structures. The mature alloys are expected to offer low cost, high strength, aluminum castings that will allow for more efficient manufacturing of Navy EFV components. The Phase I effort will involve the selection of candidate materials and manufacturing techniques, the fabrication of material specimens for nondestructive and mechanical testing, the analysis of the material composition and test results, and the development of Phase II fabrication, test, and analysis plans.

Title:High Strength Stress Corrosion Resistant Aluminum Casting Alloys
Abstract:The United States Marine Corps (USMC) is pursuing high-performance aluminum castings for structural components of the Expeditionary Fighting Vehicle (EFV). Aluminum alloy A206 has been considered for these applications; however, this alloy is susceptible to hot tearing during casting, and has inferior stress-corrosion cracking (SCC) resistance. Under this proposed SBIR program, QuesTek Innovations LLC, a leader in the field of computational materials design, will design and develop a new high-strength SCC-resistant castable aluminum alloy for the waterjet inlet housing and/or steering bucket applications. The Materials by Design® framework will use QuesTek’s state-of-the-art computational design tools for aluminum alloys, including custom thermodynamic and kinetic databases, microstructural evolution models, physics-based strength models, solidification and inoculation process simulations, and stress-corrosion cracking models. Our Phase I collaborators, Material Strategies, Inc. and Eck Industries, Inc. will assist QuesTek in Phase I alloy fabrication, castability testing and will provide process-related design expertise. In the program QuesTek will also partner with OEMs who will help define the material and process requirement matrix, and ultimately lead the alloy implementation. Concept feasibility will be demonstrated on model alloys fabricated in the Phase I program. Production-scale fabrication of the designed alloy will be demonstrated in Phase II.

Title:Autonomous Maintenance and Health Monitoring of Rechargeable Batteries
Abstract:InScope Solutions proposes to develop an intelligent battery management system for the Marine Corps that is capable of fully autonomous maintenance, management, charging and testing of rechargeable batteries. Two derivatives of this system are proposed, one designed for maintenance only functions for use in storage facilities and one with bulk charging, testing and catastrophic battery fault handling capabilities suitable for ship-board or similarly vital environments. Both derivatives share a common system architecture as well as a commonality of electrical circuitry and software. The use of Artificial Intelligence algorithms within the battery management system eliminates the need for trained personnel to supervise battery charging, and dramatically reduces the manpower required to operate the system. Extensive data communications capabilities permits remote management of the system as well as generation of notification messages by the system should any fault be detected. Beyond these hardware systems, InScope Solutions proposes to create a battery database system to decrease the logistical issues associated with tracking and managing a large inventory of batteries, and to provide an extensive data analysis and reporting capability.

Title:Wireless Intelligent Battery Monitoring and Maintenance System
Abstract:The address the Navy’s need for autonomous maintenance and health monitoring of rechargeable batteries, Physical Optics Corporation (POC) proposes to develop a new Wireless Intelligent Battery Monitoring and Maintenance (WIBAMM) system. The proposed system is based on a dense sensor network that both wirelessly monitors individual battery status (i.e., voltage, charge status, and temperature) and performs lower-power recharging to combat the effects of self-discharge during long-term storage aboard Navy vessels and at ground-based storage facilities. The innovative Intelligent Battery Monitor (IBM) sensor retrofits to any rechargeable cell and enables the Navy to easily monitor and rapidly determine the health of large quantities of batteries (over 16 million). As a result the WIBAMM system can also eliminate the danger of thermal runaway events and frequent faulty battery delivery to operators, both of which are major problems for the modern Navy. In Phase I, POC will demonstrate WIBAMM feasibility on multiple standard military batteries with a system design that provides the best value for the government with a small TOC and a ROI approaching 10x. In Phase II, WIBAMM will be ready for full-scale application by the Navy for batteries stored aboard Amphibs and MPF ships, and at ground-based storage facilities.

Title:Autonomous Maintenance and Health Monitoring of Rechargeable Batteries
Abstract:Reduce the logistical costs associated with the deleterious effects of long term storage of rechargeable lithium based batteries. The self discharge characteristics of rechargeable batteries necessitates monitoring to prevent permanent damage and attendant replacement cost. Utilize RFID technology to build a wireless system to monitor individual battery’s charge condition. Develop a portable integrated storage system that provides inductive battery charging capability, controlled by a software application utilizing a database of battery specific charge, temperature and voltage limitations. This system would raise the stored batteries from an as delivered 50% charge capacity, to 100% charge in preparation for delivery to users. Integrate the storage system into cargo shipping container that provides physical security and integrity in the event of an overcharge condition and power to the storage system.

Title:Autonomous Maintenance and Monitoring of Rechargeable Batteries
Abstract:A system is proposed that will enable large quantities (thousands) of batteries of various configurations to be transported, stored, maintained, monitored, and tracked by a single central control station. The wireless data transfer will enable monitoring of the status of these batteries by a local site representative or remote monitoring from any location or both. In addition, the system will also include provisions for maintaining, in like-new condition, large quantities of embedded batteries that would be prohibitive to replace or service in the field. The system will include innovative user friendly packaging that will not only save time during deployment, but will greatly reduce manpower required to distribute the batteries at the point of deployment. All of these features will be packaged in a standard transportable container that will serve as the central shop or service center when deployed. This structure will be a shelter that will be compatible with shore or shipboard power and be equipped with all required attachment points and fittings to comply with military as well as civilian transport.

Title:Lightweight Self-sealing Fuel Tank with Hydraulic Ram Mitigation
Abstract:The Expeditionary Fighting Vehicle (EFV) has two external fuel tanks that have a total capacity of 238 gallons, and weigh nearly 500 lbs each. The US Marines seek to reduce the weight of each external tank by 40% to 310 lbs, while not compromising survivability or capacity. Self-sealing coating technologies such as polyurea are desired; however, the added weight of this feature may present an integration challenge. The competing requirements of ballistic protection, fuel containment, and vehicle weight present a significant engineering challenge in this application. Innovative solutions that balance these performance traits are required, particularly strategies to achieve compact, low surface area fuel tanks that enable the full thickness of a polyurea coating necessary for self-sealing.

Title:Modular Lightweight External Fuel Tank System
Abstract:METSS proposes to develop a lightweight, low cost, modular self-sealing fuel tank system for use on the EFV. METSS will show that existing materials can be combined in a multi- layer, integrated, multicomponent, unibody structure to produce a fuel tank system that is stable to JP-8 fuel, impact and hydrodynamic ram resistant, and will self-seal upon impact from a 14.5 mm projectile. METSS has demonstrated this in a previous SBIR program for the Army. This modular tank construction will not be damaged by the hydrodynamic ram effect from a 14.5 mm strike, nor be subject to the initiation of a fire. The proposed tank system will be considerably lighter in weight than the existing system, and meet the Marine’s weight targets, based on light-weight fuel tank technology developed by METSS in a previous, directly related, fuel tank weight reduction program. This modular tank construction will exhibit durability to dust and sand, temperatures between -25ºF and +125ºF, and be resistant to chemicals that the tank may be exposed to.

Title:Expeditionary Matting/Soil Stabilization System (EMS3)
Abstract:Soil stabilization matting is used to provide a temporary roadway for wheeled vehicles in areas otherwise rendered impassable due to soil conditions. As vehicles traverse unimproved terrain the travel conditions quickly degrade as each vehicle digs deeper trenches in soft soil. The problems with current matting systems are the lack of strength to support the loads imposed by military equipment, failure to meet the required rates of roadway deployment and they exceed logistic system weight/volume limitations. Through an understanding of the behavior of the subsoil and the subsoil/matt interaction, TRI/Austin will design three alternative matt systems that will be easy to install, are relatively inexpensive, will permit significant large mass traffic, and that will be logistically efficient. All of these systems will be based on existing technology and commercial-off-the-shelf materials. The three alternative matt systems will be evaluated mechanically in the laboratory and with drive- over tests. The alternatives will be ranked for performance, cost, weight, volume, and ease of installation. The results of the matt development and evaluation effort will be presented to the U.S.M.C. technical representatives with recommendations for system selection and a detailed transition plan delineating the development efforts needed to get the selected system to TRL 8.

Title:Durable, Low Cost Soil Stabilization Mat Optimized for Automated Pultrusion Manufacturing
Abstract:XCraft, along with its team partner KaZaK Composites, propose to develop and produce an innovative, low cost, pultrusion-based matting for soil stabilization applications. Developmental impetus for these novel mat structures is based on a need for improved mobility of heavy tracked and wheeled vehicles over soft expeditionary terrain. Proposed improvements are focused on exceeding the current paradigm of soft soil matting technology in terms of soil stabilization performance, cost, durability and implementation expediency. Working with KaZaK, XCraft will develop and analyze several innovative matting technology candidates based on the application of advanced embedded and non-embedded textile composite structures, utilizing novel matrix and reinforcing materials such as carbon and glass fiber. Composite materials offer enormous flexibility in constituency, allowing optimization of mechanical, physical and chemical performance requirements using material and manufacturing cost as a design variable. Pultrusion will be employed to ultimately produce matting at anomalously high through-put and acceptable low cost. Optimizing each candidate concept for automated production via pultrusion will ensure low cost in production. XCraft and KaZaK have significant experience working together to develop novel composite systems for harsh military environments. Phase I will include both analysis and hardware demonstration.

Title:Advanced Refrigeration System for Non-Lethal Direct Energy Weapon System
Abstract:The Non-Lethal Direct Energy Weapon (NLDEW) system, including ADT and RF Vehicle Stopper, has significant cooling requirements that can be addressed by mechanical refrigeration systems. These include cooling of various high powered ADT solid state array or RF vehicle stopper vacuum microwave power electronics during short period of “ON” time, as well as long duration of “standby” cooling. The proposed “Advanced Refrigeration System for Non-Lethal Direct Energy Weapon System” uses a design similar to flat plate heat exchanger to offer an innovative and reliable technology to reduce the weight and volume of NLDEW, while providing improved performance, reliability and maintainability. In the proposed project, Advanced Cooling Technologies, Inc., supported by Villanova University, will develop an advanced vapor compression refrigeration system consisting of two key components: a load leveling heat exchanger with high thermal conductive Phase Change Material embedded with Graphite Nanofibers, and a highly integrated heat exchanger combining the evaporator, condenser and subcooler, to meet NLDEW cooling requirements. Phase I will demonstrate the feasibility of the concept through system trades, integration study and preliminary prototype testing. Phase II will design, build and test a full scale system, and demonstrate its ability to support NLDEW cooling requirements.

Title:Compact, Low Mass and Very Low Maintenance TMS for High Power Directed Energy Systems
Abstract:High capacity Thermal Management System (TMS) systems that can rapidly absorb peak waste heat using phase change, liquid to vapor, dissipating it gradually during normal operation, are the most ideal and most compact TMS possible for advanced weapon systems. These systems e.g. high power ADT/RF, are typically powered cyclically and intermittently with peak requirement reaching upwards to 200 kW per system; with substantially lower average thermal dissipation requirement during normal operation. Water and ammonia offer highest latent heat of vaporization of all liquid candidates; as well as providing high thermal storage density. Furthermore, their near isothermal characteristics during the phase- change and re-constitution processes are perfectly compatible with advanced micro- electronic systems that need to operate within a very narrow temperature range in order to achieve the optimal performance. TMS approach is proposed for evaluation, which uses different fluids to accommodate specific system cooling temperatures. A successful demonstration of the proposed technology will lead to full scale development and demonstration for a real system in Phase II.

Title:Compact, Lightweight and Low Cost Thermal Management System for Active Denial Technology (ADT) and High Power Radio Frequency Vehicle Stopper (RF) Sys
Abstract:Active Denial Technology (ADT) and RF Vehicle Stopper devices need compact, light weight and low cost thermal management systems to meet mission goals. Heat exchangers strongly contribute to system volume, weight and cost. Innovative heat exchanger concepts have been identified that can reduce volume, weight and cost by over 60%, 80% and 50%, respectively, thereby helping to meet the system goal of a factor of two reduction in volume, weight and cost. Under the proposed project, the innovative heat exchanger technologies will be integrated into a next generation thermal management system for ADT and RF Vehicle Stopper devices and the design will be analyzed to show that steady and transient system performance meets Navy requirements for performance, volume, weight and costs. In addition, the heat exchangers will be tested with phase change materials to evaluate performance augmentation. While meeting ADT and RF Vehicle Stopper device requirements, the thermal management system approach will also be viable for other directed energy weapons, as well as civilian applications.

Abstract:Mezzo Technologies fabricates high performance micro channel radiators, condensers, evaporators and Phase Change Material (PCM) heat exchangers. The attributes of Mezzo's products include high heat transfer/volume, heat transfer/weight, heat transfer/air side pressure drop, and unique geometry options. Directed Energy cooling systems can utilize a variety of heat exchange components, including radiators, condensers, and PCM heat exchangers. By using Mezzo's micro channel products, the size and weight of these systems can be dramatically decreased. The Phase I effort will develop designs that quantify the expected savings. The expectation exists that factor of 2 reduction in size and weight will be acheived by using Mezzo-designed products (condensers, PCM heat exchanger, and radiator).

Title:Ground Tactical Vehicle Prognostics and Health Management
Abstract:A practical and efficient solution for PHM in Military’s Ground Tactical Vehicles can be realized via combining data-driven prognostic/forecasting and analytic techniques with a dependency model-based HM scheme. QSI proposes a PHM process that is generic and repeatable across application domains in conjunction with a unified prognostics modeling framework for developing PHM solution for complex engineering systems. This approach facilitates development and customization of PHM solution in a modular fashion. Thus large parts of a solution developed for one system/platform can be reused for a similar system/platform. Utilization of dependency model-based HM techniques enables the solution to perform efficient “root cause identification”, and thereby forecast component/hardware level failures with minimal ambiguity. A notable capability of the scheme is estimation and forecasting of mission success probability for individual vehicular systems and the platform. The approach leverages prognostic outcomes in providing HM decision support in the areas of inspection and maintenance scheduling, parts and spares provisioning, and guided troubleshooting. A self-evolving knowledge-base will be incorporated in the solution for its automatic maturation and adaptation. Such capabilities make the solution an enabler of Autonomic Logistics and CBM+ objectives. The envisioned PHM solution will be implemented on QSI’s TEAMS diagnostic design and analytic platform.

Abstract:This proposal aims to develop a comprehensive, dynamic, web-based Prognostics and Health Management (PHM) framework for data mining, diagnostics, prognostics and maintenance trends. This framework will translate the data into information and will integrate and combine information from multiple models and model types (e.g., physics-based, probability-based, reliability-based, and data-driven) to exploit the specific advantages of each type. The proposed innovative idea for achieving this integrated system is to develop a comprehensive web-based application that interfaces with the vehicle sensor network (Embedded Platform Logistics System) and United States Marine Corps’ various data management systems to provide near real-time life monitoring of the vehicle components. State-of-the-art models for data preprocessing, health assessment and diagnostics, reasoning, prognostics and maintenance trends with application to the ground tactical vehicles will be reviewed. An architecture for a prototype user-friendly web application that incorporates all the toolboxes will be developed.

Title:SiCp/Al MMC Bearing Liners
Abstract:DWA Aluminum Composites proposes the use of powder-metallurgy based, silicon carbide particulate (SiCp) reinforced aluminum Metal-Matrix-Composites (MMCs) for the replacement of 4320 steel alloy bearing liners to achieve weight reduction in the gearboxes of the CH-53K helicopter. Ceramic particulate reinforced aluminum MMCs possess the properties of interest to the Navy, including 1) density on par with monolithic aluminum alloys, 2) increased tensile and compressive strength, 3) increased tensile and compressive modulus, 4) improved wear resistance, and 5) gearbox environmental compatibility. The Phase I program will concentrate on mechanical and wear screening tests for conventionally sized SiCp reinforcement and “ultra-fine” SiCp reinforcement in moderate and high strength alloys in simple extrusions. The primary questions the Phase I program will seek to answer are 1) what are the effects of SiCp size and matrix alloy composition on strength and wear properties and 2) are the strength and wear properties obtained sufficient for application to bearing liners. If the Phase I program is successful, it will help to establish lightweight MMC bearing liners with 1/3 the density of 4320 steel that can be mass produced using conventional thermo-mechanical processing of ring structures over a broad range of diameters, large and small.

Title:Large Diameter, Light Weight Bearing Liners
Abstract:The use of materials other than steel in bearing liners lead to many problems associated with variations in thermal expansion coefficients. The use of an aluminum matrix composite minimized this problem because adding ceramic reinforcements to the aluminum matrix reduces the expansion coefficient to that of the steel. In addition, the ceramic increases the elastic modulus and increases the wear resistance. This proposal uses a new spherical alumina as the reinforcement for ease of machining in addition to the other properties.

Title:Innovative Capability to Quantify Fatigue Damage and Assessment of Endurance Limit in Spectrum Load Histories
Abstract:Flight-critical components in aircraft and helicopters experience complex service and loading conditions comprising of spectrum (variable amplitude) loading during their lifetime. Due to complex interaction of several life-limiting factors during spectrum loading, particularly, multiple fatigue damage mechanisms and microstructure sensitivity, development of analytical models to accurately predict fatigue damage and service life of the material/component in spectrum loading has been difficult. Additionally, highly conservative recommendations for component inspection and retirement schedule are subsequently adopted. In this effort, QuesTek proposes to combine its expertise in microstructure-sensitive fatigue modeling with Professor James Newman's expertise in fatigue crack growth and FASTRAN software development, to apply an innovative modeling scheme to accurately predict fatigue damage and service life during spectrum loading histories. The modeling strategies will be based on the mechanisms of small/short crack growth, with consideration of relevant microstructure features, during low amplitude cycles integrated with the well- established long crack growth law. The models will be integrated into FASTRAN to enable rapid transition into Navy applications. QuesTek intends to demonstrate the feasibility of this approach in Phase I through modeling and validation against existing data, and further refine and improve the analytical models utilizing a combined experimentation and numerical simulations in Phase II.

Title:Innovative Capability to Quantify Fatigue Damage and Assessment of Endurance Limit in Spectrum Load Histories
Abstract:Analysis methods are not available to predict the life of structures exposed to spectral loads containing large cycles of low amplitude loads. The challenge is developing a computational technique to predict damage accumulation in the ultra high cycle fatigue (UHCF) regime and then integrate that into a spectral loading capability. By its very nature, all UHCF damage growth rates are small at 10E-10 m/cycle. This damage is on a size scale such that the local material microstructural features and the random nature of the size, strength and location of these features causes large scatter in the damage accumulation rates. The objective of Phase I is to demonstrate the feasibility of applying a probabilistic micromechanics approach to UHCF durability prediction. VEXTEC will extend its current HCF predictive capabilities into the UHCF regime. The approach will evaluate common aerospace materials: aluminum, titanium, and steel. The program will evaluate each material system in terms of the UHCF failure modes and mechanisms and apply that knowledge into a micromechanics based spectral fatigue durability simulation. VEXTEC will build on its vast experience in the field of damage micro-mechanics and reliability to develop a demonstrator Fatigue Simulator Tool.

Title:Thermoelectric Integrated Heat Exchanger for E-2D Advanced Hawkeye
Abstract:Advanced Cooling Technologies, Inc. (ACT) proposes an innovative heat exchanger integrated with thermoelectric devices to achieve 10-15 kW additional cooling capacity to the current Liquid Cooling System (LCS) aboard the E2-D Advanced Hawkeye. The proposed heat exchanger will reduce the cold side temperature of the LCS by 3-5°F and reject the waste heat to the hot side of the LCS using thermoelectric devices to pump heat against the thermal gradient. By raising the hot side temperature of the LCS, the ultimate heat sink (ram air heat exchanger) will be able to handle the additional heat load without size increase. The proposed heat exchanger will replace existing sections of LCS plumbing, providing a design that has minimal impact on size and pressure drop. Additional innovations in the heat exchanger design will improve efficiency and mechanical reliability by allowing direct convection heat transfer to remove heat from the hot side of the thermoelectric modules. ACT has secured the support for this project from Northrop Grumman Aerospace Systems, the manufacturer of the E-2D Hawkeye. Northrop Grumman will provide design requirements and guide the development efforts in the Phase I and II and eventually become an integrator of the technology in actual aircraft.

Title:Compact Thermoelectric-based Pre-Cooling Assembly for the E-2D Liquid Cooling System
Abstract:A 5 degree farenheit decrease in cooling temperature within the E-2D Liquid Cooling System (LCS) would translate to an additional 15 kW capacity to remove electronic waste heat. For this, thermoelectric cooling represents a compact, minimally intrusive method for achieving the desired augmentation while meeting all system constraints. However, a major disadvantage to thermoelectric cooling is the energy penalty associated, with a coefficient of performance (COP) on the order of 0.5 typical, compared to vapor-compression refrigeration cycles with COP of 3 typical. For thermoelectric cooling, the COP is directly dependent upon the packaging of the thermoelectric modules and the overall thermal resistance between the heat source and heat sink. For the E-2D LCS, Mainstream has designed a pre- cooler assembly utilizing commercial-off-the-shelf thermoelectric coolers and advanced heat exchanger designs to yield 5 „aF of pre-cooling during ground operations and 8 degree farenheit of pre-cooling during flight operations with an overall COP of 0.6 and 0.9, respectively. Due to Mainstream¡¦s extensive history with custom heat exchanger designs, the Phase I effort will focus on fabrication and demonstration of the pre-cooler at a 1:13 scale. The Phase II effort will result in full-scale demonstration units for field-testing.

Title:Advanced Liquid Cooling System
Abstract:To address the U.S. Navy’s need for innovative thermoelectric cooling augmentation for the E 2D liquid cooling system, Physical Optics Corporation (POC) proposes to develop a solid-state Advanced Liquid Cooling System augmentation module based on TEC and an extended surface liquid heat sink. The design innovations provide an additional PAO temperature drop (delta T = 5°F) upstream of the existing E-2D LCS inlet. This drop results from innovations that significantly reduce parasitic energy losses in a semiconductor structure (up to 75%), optimization of the cooling medium rate in the TEC (25% of total PAO flow), improvements in the thermal performance of the heat sink (62.5% compared with conventional technologies) and a low system turn-on time. The ALCS’s rugged modular design and reliance on mature fabrication technologies offers high reliability with a minimum MTBF of 6,800 hours. In Phase I, POC plans to design this module via CFD modeling and experimental research. A TRL-3 proof-of-concept prototype capable of removing 1,000 Btu/hr of thermal load will be assembled and tested to demonstrate feasibility of the ALCS. Refinement of this design will lead to a TRL 6 13,000 Btu/hr prototype in Phase II capable of accurately regulating the temperatures in the cooling loop

Title:Magnetic Gears for Utility Actuation Gearbox Applications
Abstract:Although published magnetic gear designs have been demonstrated in various and sundry academic settings, none are viable for industrial scale / military applications. Yet the technology remains enticing. The favored solution involves a topology that capitalizes on a cycloidal operation, but with axial flux that allows the objectionable forces to be canceled. This favored topology operates with a single air gap between torque generating MMF sources and allows for a pseudo drive topology using a transverse (i.e., radial) flux operating in the strong normal direction. Note that the novel solution proposed has never appeared in literature and is proprietary to this team. This team has designed and constructed 3 versions of the planetary gear, the topology that has received the greatest attention in the literature. Two weaknesses are inherent to the operating principle. (1) It employs two air gaps, and (2) the central structure must be laminated and sustain torques equal to the sum of those on the high and low speed shafts. This team has just completed the construction of its 2nd generation axial flux cycloid gear. This topology can realize much higher torque ratios without cogging, and can be made to balance the primary forces the bearings.

Title:Pericyclic Magnetic Continuously Adjustable Transmission
Abstract:To address the Navy’s need to demonstrate the feasibility of developing a flightworthy magnetic-based transmission for utility winch and reeling applications, Physical Optics Corporation (POC) proposes to develop a new Pericyclic Magnetic Continuously Adjustable Transmission (PM-CAT). This proposed magnetic gearbox design is based on pericyclic motion with direct magnetic coupling. The innovative torque-speed governor mechanism in PM-CAT will enable the device to operate as a variable transmission with a forward/reverse direction coupling. This device offers stepless torque-speed conversion and is a noncontact gear mechanism without lubrication. It is a compact and reliable solution that directly addresses the H-60/53 helicopter program requirement to increase service availability for mission-critical applications. In Phase I, POC will analyze the proposed gear, and demonstrate the feasibility of the PM-CAT in a simulated environment. We will then build a laboratory-scale prototype to verify the design principle with respect to volume, weight, and performance metrics such as stiffness, magnetic hysteresis, gear ratio, efficiency, and torque density. In Phase II, POC will fabricate a proof-of-concept prototype, perform qualification-type testing, and further optimize the design based on additional objective metrics such as vibration, torque ripple, and overall cost.

Title:Magnetic Gears for Utility Actuation Gearbox Applications
Abstract:Modern rotary wing naval aircraft posses numerous winching and reeling systems to handle cargo, rescue operations, and sensors such as ASW devices. These systems require maintenance & lubrication, and may break down or degrade with age due to mechanical gear tooth wear – This can have severe impacts on mission availability, reliability, maintenance, and logistics. Magnetic gears and couplings offer the promise of low maintenance, low friction, high efficiency, zero wear, and now with new magnet technology, high torque densities. The basic principles and allure of magnetic gears goes back at least 70 if not over 100 years! However now, with the advent of modern high strength magnets, and innovative topologies that take full advantage of them, the promise highly efficient magnetic gearing is becoming a reality. Trex Enterprises proposes to design, develop, and test an airworthy magnetic gear based gearbox for utility actuation gearbox applications.

Title:Geospecific Displacement Maps for Real Time, Stereoscopic Training Simulation
Abstract:Displacement mapping is a rendering technique which allows small details, represented as height displacements (often in the form of a texture map), to be applied to a polygonal mesh. The objective of the proposed effort is to develop an innovative automated process that unlocks the advantages of real-time displacement maps (and related technologies), combined with geo-specific two and three dimensional source imagery, for providing highly- complex terrain surface regions in virtual environments for real-time training simulators. In Phase I, we will work to develop an innovative approach to incorporating displacement mapping and related techniques into a real-time visual system. The goal of this approach will be to provide an automated capability, requiring little or no manual database generation effort. A procedure for generating the displacement map from mono and stereo imagery will be developed. Existing published research in these areas will be leveraged, but with a specific focus on techniques that can be performed “on-the-fly”, in real-time. Challenges which will be addressed in Phase I include any impediments to a complete end-to-end solution, sensor simulation issues, patch insertion issues, occulted data hole issues, multiple source data issues, modeler time and skill issues, as well as compatibility issues with other simulation systems.

Title:Geospecific Displacement Maps for Real Time, Stereoscopic Training Simulation
Abstract:JRM proposes a new 3D material-classified displacement-map (MCDM) approach with associated automated algorithms for rapid terrain database generation directly from geo- specific source data. The MCDMs will exploit the latest nVidia GPU displacement map shader technology for highly-realistic real-time physics-based visible/sensor simulation of high-resolution terrain insets. At the conclusion of a successful Phase II, JRM anticipates a prototype DBGS and real-time rendering system capable of supporting rapid mission planning and rehearsal requirements -- from raw satellite/GIS data sources into high-fidelity visible/sensor simulation -- in one day or less. In the phase I, JRM proposes four tasks: (1) Investigation and design of a GPU-compatible 3D MCDM data model and format; (2) Design studies of 2D/3D image/data-processing algorithms for automated production of MCDMs, and assessment/incorporation of already-available off-the-shelf tools for handling some of these tasks; (3) Design studies of stereoscopic GPU shader techniques for physics-based rendering of databases based on 3D MCDM, and (4) a Proof-of-concept Demonstration, involving automated MCDM generation of a high-res inset from 2D and 3D satellite source data, and real-time simulation of notional SAR, visible CCD, near-IR, MWIR and LWIR from that MCDM.

Title:Sentient Adaptive Respone Cruise Harness (SeARCH) for Autonomous Sonobuoy Gliding & Navigation
Abstract:Barron Associates, Inc. has proposed a unique and innovative design for precision-guided sonobuoy delivery. The basic glide harness design uses a novel split wing design that maximizes both wing area and span in a concise package, thus greatly improving the aerodynamic performance and range capability of the vehicle. The wings are designed to minimize the impact on the interior sonobuoy volume. Furthermore, the deployment of the wings and control surfaces is accomplished using the drag force of the sonobuoy parachute, thus removing the need for any active or passive actuation components on the sonobuoy. After the wings and control surfaces are deployed, Barron Associates’ adaptive guidance routines will control the vehicle, bringing it to an accurate final position for sonobuoy release. The guidance algorithm being proposed here (LOER) has already been developed by Barron for several other government projects and is well suited to the task of guiding a glide- capability sonobuoy. The proposed Phase I effort will consist of both vehicle design and the building and flight testing of a prototype vehicle. The prototype vehicle will be used both for wind tunnel testing, and as a flight demonstration of the basic vehicle concept and the installed software.

Title:Glide Away Precision Sonobuoy
Abstract:STARA Technologies is the leading developer of miniature guided parachutes. Over the past ten years STARA has fabricated light weight guided parachute systems for the US Army, Department of Defense, Department of Energy and other Federal Agencies to precisely deliver light weight payloads, such as, Provider Resupply Pods deployed from an unmanned aerial vehicle (UAV), communications relays, medical supplies, intelligent munitions, and sensors of various kinds. In related work, guided parachutes were used to deliver cylindrical payloads (5 inch diameter, 30 inch length, 40 pound weight) dropped from an UAV to a landing accuracy of 50 meters CEP (circular error probability). The parachute and guidance unit used for cylindrical payloads are housed in a 5 inch diameter, 12 inch length fiberglass tube. A natural extension of the guided parachute aerial delivery system will satisfy requirements of SBIR Topic N102-117, Glide Away Precision Sonobuoy with low risk. Using the same guided parachute system components, matched to a rectangular payload, bundles were dropped from 25,000 feet with a landing accuracy of 36 meter CEP. Using a 6:1 glide parachute, dropped from 25,000 feet will glide 25 NM and place a 40 pound sonobuoy within 50 meter CEP of the intended impact point.

Title:Glide Away Precision Sonobuoy
Abstract:The P-8 Poseidon Maritime Patrol Aircraft will soon be replacing the P-3 Orion. The P-8 flies at a much higher altitude than the P-3, and needs a new sonobuoy guidance system to allow sonobuoys to be placed accurately without the aircraft having to descend. This multi- phase SBIR project will develop the “Glide Away Precision Sonobuoy” (GAPS), a high- aspect-ratio parachute and navigation system that will fly a sonobuoy from 25,000 feet to a target area 25 nm away, with sub-50-yard accuracy. GAPS will be compatible with existing sonobuoy deployment systems and will require minimal changes to existing sonobuoys. When manufactured in quantity, GAPS will cost less than $1000 per sonobuoy. By enabling allow aircraft to deliver sonobuoys accurately from altitude, GAPS yields significant fuel savings, hence the Navy will realize a quick Return On Investment. Phase I will design the key elements of GAPS, followed by component construction and testing in the Option. Phase II will develop and test a complete prototype program. We will develop a full-scale version of GAPS and integrate it with a sonobuoy to for field-testing under realistic conditions. Phase III will include testing on Navy aircraft and the commencement of production and sales.

Abstract:In this NAVY SBIR Phase I program, we propose a radio frequency (RF) direction finding sensor for low probability of intercept (LPI) RF radar system. This sensor consists of a dielectric fisheye lenses and an innovative focus plane detector array (FPDA). The fisheye lenses, as a RF antenna, have been broadly used in camera and electronic-optical systems (from visible to infrared wavelength). In this program, using dielectric materials such as teflon or sapphire, we will fabricate fisheye lenses operable in RF/millimeter wave regions. The lenses can project the RF signal over a semi-sphere onto its focus plane. A novel FPDA based on emerging spintronic devices, with each element being much smaller than 0.1 mm, will accurately detect the diffracted field distribution produced by the lenses. The center of the distribution is related to the direction of the incident waves. The direction can thus be extracted from the position of the distribution in the focus plane and parameters of the fisheye lenses.

Title:Miniature Portable Ultra-Cold Atom Source without Active Pumps
Abstract:Research centers on the development of a purely passively pumped miniature ultrahigh vacuum system capable of producing Bose-Einstein condensates and related forms of ultracold matter. The approach is based on a double-MOT system incorporating an atom chip. Key issues concern the management of the excess thermal component of the cooled alkali metal species as well as the elimination of trace impurity gases. Experimental work concentrates on investigation of candidate getter elements and demonstration of getter technology. Efficacy of the approach is to be established in a proof-of-principle demonstration achieving nanotorr vacuum levels in the atom chip section of the system while it is also subject to the high thermal background load of alkali metal vapor. Design work centers on new vacuum cell fabrication techniques and integration of the passive pump elements to complete the miniature cell system design having a volume of less than 100 cc.

Title:Miniature Ultracold Atom Chamber
Abstract:Cold atom sensors have a variety of uses as next-generation precision measurement devices for geolocation, sensing, and timekeeping. Sensors such as accelerometers, clocks, magnetometers, and gravity gradiometers have been developed using cold or ultracold atomic systems. While some of these sensors require the preparation of cold (temperature ~ìK) atoms in a Magneto-Optical Trap (MOT), many require an additional step of cooling to reach the ultracold temperatures (temperature ~nK) attained in a Bose-Einstein Condensate (BEC). Although the physical configuration of these sensors may be different, all the sensors in this suite share a common set of required instrumentation. The proposed work will develop a critical component common to all practical, fieldable cold atom sensors: a miniature, portable, ultracold atom chamber. The atom chamber consists of a glass cell, an alkali atom dispenser, and a Non-Evaporable Getter (NEG) pump. The proposed work will result in a miniature Ultra-High Vacuum (UHV) chamber without an active pump that will enable the next generation of compact and portable cold atom sensors.

Abstract:A vacuum system with pressures typically below about 10-9 torr is required to mitigate thermal background collisions when producing Bose-Einstein condensates (BEC) and other forms of ultracold matter. Traditional setups contain multiple vacuum chambers, often employ the use of large ion pumps, and take up significant space on a full-sized optical table. While ultracold matter has great potential in advanced applications, these large vacuum chambers and complex setups are considered a serious impediment to application development. In performing this project, Triad Technology will produce a vacuum chamber smaller than 5cm by 5cm by 5cm in size for use as a source of ultracold matter. The chamber will meet the necessary vacuum level requirements using a unique geometry that takes advantage of a novel processing and pumping techniques.

Title:Inherent Electrical Conductivity in Qualified Aircraft Transparency Materials
Abstract:This program seeks to impart P-static control and EMI protection within current aircraft transparencies. This will be accomplished by using multiple carbon nanotube based composite layers to impart electrical conductivity to materials used in the manufacture of F- 18 canopies. Eikos, along with teaming partners proposes to layers of CNT composited with polycarbonate and/or acrylic to reach the desired combination of properties called for in this program. The result of this work is a subscale demonstration of this nanocomposite that strongly indicates the potential to provide a full range of protection to environmental and operational conditions. The composite part should form a highly durable transparent and conductive shield useful on all types of transparencies. The overall goal is to apply Eikos Invisicon® technology to layered polycarbonate substrate for optimal EMI protection and within the protective acrylic top coat for improved ESD mitigation for F-18 canopies. The proposed approach allows deposition by common atmospheric processing methods that are scalable to protect large areas and complex curvature.

Title:Highly Conductive and Transparent Graphene Filled Acrylic
Abstract:Graphene nanoparticles (platelets) exhibit extremely high conductivity and transparency, excellent mechanical properties, and facile processability that can be supplied at much lower cost than other carbon forms like nanotubes. Graphene also features tailored chemical functionality, which allows uniform dispersion of graphene platelets within a host polymer like acrylic. We will formulate Graphene-filled Acrylic (GFA) by developing graphene platelets in suitable liquid dispersions which are then used directly to produce PMMA acrylic plate. This provides a percolative or conductive network of graphene particles within the acrylic matrix at low graphene loadings, which is important for good optical properties. GDL and our program Team members each provide the necessary expertise to perform this work. This includes several leading graphene researchers and one of the largest suppliers of cast and cast/stretched acrylic to the requirements of MIL-PRF-8184 and MIL-PRF-25690 and a leading supplier of aircraft transparency material for many years. GFA samples will be produced and electrical, optical and mechanical tests performed to assess performance against established material requirements.

Abstract:This Small Business Innovation Research (SBIR) Phase I project proposal to the U.S. Department of Defense (DoD), Navy, requests funding for Innova Dynamics, Inc. to enable innovative manufacturing of robust, non-delaminating, highly conductive aircraft transparency materials through Innlay™ surface-embedding of military-spec polycarbonate and acrylic. The proposal addresses known challenges with existing conductive aircraft transparency technologies, such as the problematic issue of coating delamination, leading to negative optical properties and high repair and replacement costs, as well problems associated with under-performing conductive transparency materials, such as inadequate charge dissipation and inadequate electromagnetic interference shielding. The primary innovation of the current proposal is to use Inlay™ surface-embedding to develop an inherently conductive aircraft transparency based on currently qualified transparency structural materials wherein the conductive properties are "built-in" through Innlay™ as opposed to applied via coatings to overcome the above challenges. Sheet resistance of 80% are expected, along with optical and mechanical properties meeting appropriate military specifications.

Abstract:Long CNT arrays are important to develop high performance material for coaxial cable. Long nanotubes reduce the number of junctions and twist angle in CNT yarn, resulting in increased mechanical, electrical, and thermal properties. General Nano, LLC (GN), the lead applicant and University of Cincinnati (UC) spin off company, owns the exclusive license for the catalyst that has grown the longest CNTs (22mm) ever recorded. GN's long CNT arrays can be spun into CNT yarns and ribbons for applications such as coaxial transmission lines. GN and UC partnered with General Cable (GC) to accelerate commercialization. GC has supplied coaxial cable to the commercial and military markets for more than 20 years. GN and GC forged a relationship in 2009 and identified CNT coaxial cable as its top priority application prior to the Navy’s SBIR solicitation. In May 2010, GN applied CNT yarns and ribbon to GC coax for initial testing. Results are forthcoming. In the SBIR Ph I, the team will demonstrate the benefits of long CNTs spun into yarns and/or braided materials compared to conventional coax. GN will manufacture and characterize the CNT materials, UC will provide quality control, and GC will perform the comparative analysis.

Title:Carbon Nanotube Coaxial Transmission Lines
Abstract:A key technology enabler for next generation ISR systems is low loss, lightweight, flexible wire and cable, particularly the RF power routing from the fuselage to the rotodome in the E- 2 Hawkeye airborne early warning aircraft, which requires specially designed copper based coax Aircraft Transmission Lines (ATL). Copper is the established choice of conductive material for these ATLs, but copper’s susceptibility to flex failure and increased insertion loss with heating and frequency in the E-2 platform limits ATL performance and often requires phase compensation. As an alternative to copper, lightweight and low resistance carbon nanotube (CNT) based conductors can be considered for use in advanced ATL designs. We propose to design a CNT-based coaxial cable, utilizing our CNT wires and tapes, for high power, high frequency applications, which can withstand the temperature extremes, very high electrical current, mechanical stress and vibration that current ATL cables are subjected to. The aim of Phase I is to develop the models and materials properties necessary for the cable design, which will be done during the Option. Phase II will consist of constructing and testing the ATL cable in preparation for qualification and insertion into next generation ISR systems.

Title:Gear Hobbing Predictive Model
Abstract:Hobbing is one of the most efficient and often used machining process to manufacture helical and spur gears. Hobbing process is a widely preferred to make gears as it can achieve near net shape with excellent tolerances and good surface finish at faster production rates. Gear hobbing is a complex machining process which requires a detailed understanding of the interaction of processing variables, the hobbing tool design and the material removal mechanisms. A clear understanding of the cutting forces and the temperature at the interface of the hobbing tool and gear blank workpiece interface is essential to predict the cutting induced residual stresses. The hobbing tool geometry along with the axial feed rate and the rotation speed of the tool dictates the chip shape. Because of the nature of the gear hobbing process which involves progressive cuts and varying material removal rates at the entry and exit of the cutting zone, the hobbing tool typically experiences non-uniform tool wear. Hobbing tools are expensive and excessive tool wear impacts increased tool interface temperature, chip shape and the gear surface finish quality. Industry needs a finite element method process modeling system to simulate the gear hobbing process to predict the chip shape, cutting load, temperature at the interface, tool wear and the cutting induced residual stresses. Commercially available, finite element method based process modeling system, DEFORM is widely used to model machining processes as well as material deformation and heat treatment processes. At the end of phase I base part of this project, we propose to demonstrate a proof of concept predictive models for analyzing forces, temperatures and residual stresses encountered during a typical gear hobbing process. In addition, it is also proposed that we will complete a typical heat treatment process model for a gear to demonstrate the capability with in DEFORM to model diffusion based carburization process to predict case depth, phase transformation during the quenching process to predict marternsitic volume fraction and any retained austenite in the gear as well as the residual stress distribution in the gear due to the heat treatment process. At the end of phase I option part of this project, we propose to investigate tool wear models, study the suitability of application of inverse methods to calculate material flow stress data at the high strain rates and evaluate options to improve computational efficiency of the machining processes.

Title:Gear Hobbing Predictive Model
Abstract:This program will demonstrate the feasibility of innovative physics-based modeling of gear hobbing to predict and improve residual stresses and heat treat distortions while reducing production cycle times and costs of transmission gears. TWS will develop a general, validated, physics-based modeling capability for the gear hobbing process, resulting in detailed chip formation and residual stress prediction. This will be achieved through both a detailed finite element modeling of tool-workpiece interaction, and CNC toolpath-level analysis. The combined outputs of these comprehensive models will provide the ability to predict machining-induced residual stresses and their effects on distortion from subsequent heat treatment, and determine interactions between machining process changes and cost, cycle time and workpiece characteristics. Feasibility will be demonstrated by: 1) advancing physics-based machining modeling for gear hobbing processes, 2) developing physics- based gear hobbing predictive models based on finite element modeling, and 3) validating these physics-based models against machining experiments. Anticipated results results of the program will: (1) predict residual stresses, forces, temperatures, and tooling performance for hobbing; (2) improve fatigue life of gear components through residual stress management while reducing cycle times and cost; and (3) advance knowledge of material removal mechanisms in gear hobbing and their effects on post-machining operations.

Abstract:Optical CDMA is most suitable to be applied to high speed LAN to achieve contention-free, zero delay access, where traffic tends to be bursty rather than continuous. Channel assignment is much easier with CDMA. CDMA isolates irregular channels so that they do not influence other channels, CDMA can be efficiently used in conjunction with TDMA and WDMA on multimedia communication networks where multiple services with different traffic requirements are to be integrated.

Title:Integrated Optoelectronics for Optical CDMA
Abstract:CDMA is a successful network technology for the wireless industry which relies totally on conventional integrated circuits. The same architecture is equally appealing for telecommunications and is considered an optimum choice for next generation FTTH networks if only low cost implementations were available. The persistent high costs are driven by disparity between optical and electrical components which include WDM capability on the one hand and digital processing on the other. What is required is the ability to merge these onto a single integrated platform so that signals could remain optical at high speeds right to the point that OE conversion was essential. With both capabilities on one die, cost goes down and performance goes up. These same attributes apply to airborne communications. The security enabled is a key aspect and thus multiple recent efforts have focused on the addition of existing PIC devices to a standard CMOS platform. ODIS offers a different solution in the form of POET, a III-V complementary HFET technology on the same integrated circuit as the wavelength division components for OCDMA. This approach achieves the goal and has already solved the main issue of technology compatibility. In this SBIR , POET will be demonstrated for OCDMA.

Title:Affordable, Reconfigurable Aerial Refueling Part-Task Trainer
Abstract:This project will develop innovative part-task trainer (PTT) concepts for a new generation PTT that is affordable due to application and integration of COTS simulation components utilizing recent hardware and software technology advances. Navy aerial refueling (AR) receiver aircraft are equipped with a probe that plugs a fuel receptacle encircled by a basket attached to a tanker aircraft hose. The common aerial refueling task for all combinations of receiver aircraft and tankers is “plugging the basket and safely receiving fuel”. This task is performed on calm clear days, but also during a large variety of environmental and time-of- day conditions and during risky malfunctions and emergency conditions. A simulator allows practice until proficiency is achieved without waiting for a real world bad weather or emergency condition. A dedicated PTT for AR training creates an opportunity to assemble the best simulation technology available while achieving “affordability” by not making performance or cost compromises for other training tasks. AVT Simulation has experience in development and fielding of affordable reconfigurable PTT. They are based on AVT’s Modular Simulation Architecture. AVT has several years of experience with simulation of the aerial refueling process through participation in USAF and Air National Guard aerial refueling simulator upgrades.

Title:Affordable, Reconfigurable Aerial Refueling Part-Task Trainer
Abstract:We propose to research and develop refueling training for aircraft (including fixed wing, helicopter and tilt rotor) using the probe and drogue refueling system. We will train the pilots of the receiver aircraft; the refueling aircraft will be automatically simulated. We will compare three visual technologies: Two-dimensional large field-of-view projection; Three- dimensional large field-of-view projection; and Three-dimensional head-mounted displays. One of these technologies will be selected for development. The training will take place only in the air, that is training sessions will start with initial conditions of both refueling and receiver aircraft already flying at approximately the same altitude. The trainer will accommodate the simulation of challenging environments including night, high turbulence and crowded airspace conditions. Flight controls and displays of the receiver aircraft will be limited to those necessary to perform pre-refuel positioning, approach, contact, refueling and termination of refueling mission. Within the flight envelope determined by these maneuvers, the control response of the receiver in the developed trainer must be correct and precise. The research shall focus on providing an integrated set of visual and kinesthetic cues that affect aerial refueling performance. In Phase I we will show the technical feasibility of this type of trainer.

Title:Affordable, Reconfigurable Aerial Refueling Part-Task Trainer
Abstract:Aerial refueling (AR) is a critical component to the success of the Navy’s air military operations, enabling modern combat aircraft to greatly maximize their mission capabilities. The Navy’s use of a probe for AR allows refueling from a wide variety of tanker aircraft, yet this type of refueling does place the burden of establishing a contact squarely on the receiver pilot. Flight simulator time is limited, so using a full flight simulator to practice in-flight refueling is often not the most efficient use of resources. The performance requirements associated with a full flight simulator are not tailored to support the unique requirements of the aerial refueling mission. Limited field of view, inability to accurately display objects close to the aircraft, and simplified tanker flow field modeling are some of the major factors that affect the quality of training. A Part Task Trainer (PTT) designed to support aerial refueling mission requirements would supplement this critical training. By optimizing the performance of the Part Task Trainer to support the unique requirements of the AR mission, the simulator can provide more effective training at lower overall cost.

Title:Pyrophoric Nanoparticles for IR Decoys
Abstract:Pyrotechnic and pyrophoric IR decoy flares protect military aircraft from IR seeking surface- to-air missiles by closely mimicking the electromagnetic signature of the aircraft in order to divert the missile from its target. Pyrophoric based decoys have advantages over pyrotechnic technology in that they are more covert, are less likely to start fires, and produce a spectral signature that is more effective against dual spectral seeking MANPADs. Here we investigate the use of pyrophoric nanoparticles in IR decoy devices where control over the size, shape, surface, and aggregation state of the nanoparticles is optimized to increase the intensity and tune the spectral signature when exposed to air.

Title:Nanostructured Particles with Designed Mid-Infrared Spectral Emission
Abstract:Infrared flare countermeasures are used for protection of aircraft from IR-seeking surface- to-air missile by providing an intense IR signal, overpowering any other signal and misleading the threat sensor. Recently, advanced threat sensors have begun to monitor multiple optical bands and ignore conventional decoys. More advanced decoy systems have some spectral control over thermal emission, but are still limited. Hence, a critical need exists to develop a next-generation decoy platform that produces sufficient thermal emission in the wavelength regions of choice and is tunable to match the specific spectral thermal emission of particular aircraft. TIAX proposes to demonstrate the power and flexibility of nanostructured particles to meet the demand for these advanced decoy systems.

Title:Cavitation Stripping of Hard Chrome Plate
Abstract:Electroplated hard chrome is used extensively for aerospace and industrial applications because it is wear resistant, corrosion resistant, has a good surface finish and has good adhesion. Naval aircraft use chrome plating on landing gear components because of these characteristics. However these coatings eventually wear and have to be stripped and replaced. Stripping the chrome coating requires the use of acid baths, which generate waste through air borne contaminants, spills, drag-out, and bath fluid disposal after chemical activity is reduced. Naval facilities are faced with increasing costs to comply with regulations concerning these hazardous waste streams. Ormond's proposed solution is to replace these chemical baths with waterjet cavitation stripping which can economically strip hard chrome using only water that can be recycled in a closed loop system. The equipment required is readily available at Navy Repair and Overhaul centers which allows for rapid adoption of the technology at low cost to the government. The process differs from the high pressure waterjet stripping used to remove thermal barrier coatings only in that it uses Ormond's cavitating nozzles to effect rapid coating removal without damage to the substrate. The process will also be applied to HVOF and other candidate chrome replacement coatings.

Title:Liquid-Nitrogen-Infused Stripping Apparatus
Abstract:To address the Navy’s need for nonchemical chrome-stripping technologies, Physical Optics Corporation (POC) proposes to develop a new Liquid-Nitrogen-Infused Stripping Apparatus (LISA). This proposed apparatus is based on application of a highly pressurized liquid nitrogen jet combined with the application of ultrasonic excitation. The innovation in coating removal technology will enable LISA to perform selective stripping of hard chrome plating without damage to the underlying substrate, corner radii, bearing faces, or adjacent critical features. Therefore, this system offers the ability to repair and rework worn and damaged metallic coatings on landing gear and hydraulic actuators for Navy aircraft, such as the F-18, which directly addresses the PMA-265 requirements for hard chrome removal by nonchemical means. In Phase I, POC will demonstrate the feasibility of the LISA process by removing the AMS-2460 compliant hard chrome coating from Navy flat and round test coupons and will prepare a cost analysis on the process. In Phase II, POC plans to develop a prototype of the LISA device to demonstrate the effectiveness of a hand-operated tool that combines the application of liquid nitrogen and ultrasonic vibration to solve the Navy’s problem of hard chrome coating rework for operation in Navy repair and overhaul facilities.

Title:Predictions of the Acoustic Nearfield on a Carrier Deck
Abstract:The noise levels caused by the jet plumes of modern high-performance military jets are a health hazard to nearby service personnel as well as a significant fatigue load. A methodology is proposed to derive source models for supersonic jet engines which can be used to predict propagation into the near- and far-field. Proprietary experimental databases will be used to express the source models as partial fields and wavepackets. Partial fields are calculated in a way that represents as much of the total energy in as few basis functions as possible. The underlying physics are not considered, but this approach is very robust since the capture of the total energy is the goal. Wavepackets have a higher physical relevance and if a deep understanding of the physics is available, predictions of jet noise sources may be made for configurations that have not been explicitly tested. These models will be integrated into a leading commercial vibroacoustic code and the sound will be propagated using the Boundary Element Method (BEM), which can model the effects of reflecting surfaces such as the aircraft carrier deck or jet blast deflectors without the meshing difficulties or extremely high computational expense of the finite element method.

Title:Predictions of the Acoustic Nearfield on a Carrier Deck
Abstract:On a carrier deck, navy personnel operate in close proximity to high-speed jets. They are, therefore, exposed to high intensity jet noise resulting in possible severe loss of hearing. The objective of the project is to develop jet noise prediction capability for quantitative assessment of the acoustic environment on an active carrier deck. Such assessment would allow the identification of noise hot spots to be avoided. Jet noise consists of three principal components; the fine-scale turbulence noise, the large turbulence structures noise and the broadband shock-cell noise. For military jets, the large structures noise is most intense and dominant. It is the focus of this project. Specifically, the aim is to develop a physics-based prediction method. It is known that large turbulence structures are spatially and temporally coherent. The noise is highly direction. The mechanism is Mach wave radiation. All these important characteristics will be incorporated into the model prediction theory. The theory will follow the highly successful Tam and Auriault (1999) fine-scale turbulence noise theory with the characteristics of fine scale turbulence replaced by those of the large turbulence structures. The Green’s function method will be used to propagate noise from source to the near and far field.

Title:Predictions of the Acoustic Nearfield on a Carrier Deck
Abstract:A numerical method for extrapolating jet noise from near-field microphone array to far field points will be developed. This software is needed to provide the source function to enable the Navy to use a commercial acoustic propagation code to predict the noise levels at the crew locations of aircraft carrier decks. The ultimate goal is to determine the benefit of applying noise reduction technology such as chevron nozzles. The nozzles will be tested in acoustic measurement facilities and the results will be transferred to the operating environment using the software. A sophisticated extrapolation model is required because the source of supersonic jet noise is highly extended and coherent, rendering simple point source models invalid. Several groups approach this problem by considering a source distribution on a conical surface surrounding the jet, and making microphone measurements on this surface. In contrast, this effort will consider the source to be within the jet plume, where it actually is, and the microphones outside the flow, where they are. Correct location of the source will simplify the measurements and the numerical effort. A novel technique that has elements in common with near-field acoustic holography and beamforming will be applied.

Abstract:DDC will implement an innovative advanced Bandwidth Enhancement Block to raise sustained data write performance to over 500MB/s. This block adds to an existing architecture (already deployed by the military). The result will be very low SWAP as it is not necessary to run several drives to obtain the required speeds. Within the desired SWAP, the system can scale to well over 1GB/s write speeds, and can support drives in excess of 2TB. The current system will be restructured as an easily expandable rack and backplane solution. This includes an I/O slot that allows for card based support of a wide variety of sensor configurations. The FPGA design also allows for new memory densities to be "plug and play" - a new card can be inserted, without the need to pull the hardware or perform any programming. In that this system is "auto-sense", the inclusion of a front panel OLED will allow for simple and informative field system monitoring. The overall approach allows for rapid configuration of a wide variety of sensor combination, standards, and memory density required by the military. DDC is open to working with the customer for an optimal combination of features.

Abstract:To address the U.S. Navy PMA-265 need for multiprotocol supporting mass-storage aircraft data recorders, Physical Optics Corporation (POC) proposes to develop a new Automatic Real-Time, Reconfigurable interface Generalization Hardware (ARRGH) multiprotocol data recorder. This proposed device is based on dual-step interface transcoding, field- programmable gate arrays (FPGAs), a parallelized SSD disk storage array, and interface specific daughterboards. The innovation in data transcoding directly and efficiently provides transcoding between almost all digital data standards, while the novel data storage solution supports sustained write speeds in excess of 500 MB per second with over 1 TB of data capacity. The unique daughterboard-based hardware design future-proofs the design, while the novel inclusion of interface programming memory on the daughterboard automates the configuration process. When coupled with the ARRGH’s native ability to provide in-situ testing of sensors and cables, the ARRGH directly addresses the PMA-265 need for cross- platform data recording solutions. In Phase I, POC will develop a complete design document and fabricate a limited-capability proof-of-concept prototype that meets the major specifications. In Phase II, POC will optimize the ARRGH software and hardware and fabricate a TRL-6 prototype data recorder sufficient for flight testing and direct transition to Phase III production.

Title:Multi-Polarization Inverse Synthetic-Aperture Radar (ISAR) for Automated Ship and Small Craft Classification
Abstract:RDRTec Inc. and SAIC propose to develop, compare, and test innovative multi-polarization techniques that will both increase the information content in Inverse Synthetic-Aperture Radar (ISAR) images as well as exploit that information to increase the robustness of maritime classification tools that assist sensor operators in rapidly and accurately classifying ships and small boats in the littoral zone. The state of the art in ISAR assisted target recognition uses single polarization image frames. The coherent nature of both SAR and ISAR processing can make it subject to a considerable amount of speckle (or glint of unresolved scatterers) as well as “holes” in the image where the scattering mechanism provides a cross-polarized response to the antenna. Speckle reduction improves the visual quality of SAR and ISAR imagery, and it permits the application of more sophisticated image processing and/or improves the robustness of current feature extraction algorithms. Multiple polarimetric processing techniques have been developed for SAR processing that reduces these problems significantly. If applied to ISAR, these techniques have the potential to significantly improve the quality of the feature extraction and thus classification performance. In addition, different polarization responses are indications of features. For example, if dual circular polarization responses are sampled on receive, resolved scatterers will be separated by channel into even and odd bounce scatterers. This property has the potential to clearly identify the two-bounce scattering at the intersection of the deck and the superstructure from the flat plates of the hull and the superstructure. The proposed work compliments ongoing work being performed by RDRTec and SAIC in the areas of single polarization ISAR and multi-sensor (ISAR and IR) assisted target recognition. Simultaneous dual polarization ISAR data on a small boats and simulated full polarization data will be used in Phase 1 analysis.

Abstract:Extensive research has shown that multi-polarization SAR data improves ship detection over single-polarization data. Via simulation, researchers have shown that polarimetric SAR and ISAR data improves ship classification. User Systems, Incorporated (USI) plans to use the polarization whitening filter (PWF) algorithm for speckle reduction and the Cameron Decomposition algorithm for feature extraction to improve ship and small craft classification using multi-polarization ISAR data. The PWF algorithm adds the polarimetric channels without the loss of resolution. The Cameron algorithm has proven to be effective in relating the polarimetric information to the physical shape of the targets. For the Phase I effort, USI plans to use available polarimetric SAR data with ships to provide preliminary results.

In particular, PRA will leverage its experience in an M-on-N algorithm developed for the U.S. Army under previous SBIR contracts to support interceptor- target assignment in multiple target environments. HETSA will be based upon a heuristic metric where target selection is accomplished to optimize mission success. The algorithm will assign a weighting to the target based upon its assessed value, the number of other missiles in the scene addressing the target, the risk associated with not engaging the target and other missile parameters. PRA will modify its existing M-on-N algorithm for optimized initial target selection for the Harpoon missile system and will adapt the algorithm for changing target priorities and missile engagement parameters. The HETSA approach will provide an autonomous target engagement capability that combines both fire-and-forget with the high-probability of kill of shoot-look-shoot during multiple simultaneous engagements (MSE). PRA plans to team with Boeing in Phase II to implement HETSA into a simulator or simulation in order to demonstrate its performance.

Title:Heat Resistant Visual Landing Aid (VLA) Lighting Fixtures for Ship Flight Decks and Expeditionary Air Field (EAF) Matting
Abstract:Visual Landing Aids are required for visual acuity to safely guide aircraft during night and/or low visibility aircraft operations, for general lighting and navigation. The current generation of VLAs was designed to withstand loads associated with existing aircraft. Future aircraft are expected to generate more severe exhaust loads that could threaten the integrity of these lighting fixtures. Indirect aircraft exhaust temperatures of approximately 350C for long dwell periods as well as near-direct temperatures of approximately 900C for relatively short durations are expected. Such temperatures, in conjunction with the relatively high convective coefficients characteristic of jet flow, have been shown to generate significant temperature gradients in glass windows. The resulting thermal stresses, particularly in conjunction with pressure loads, can lead to window failure. Similarly, internal seals, electronics, and structural components in the VLAs can be compromised by high temperatures or differential thermal expansion. The goal of our Phase I work will be to establish a VLA design that can accommodate all thermal and mechanical loads from future aircraft such as the F35 and be a form, fit and functional replacement of currently fielded VLAs.

Title:Heat Resistant Visual Landing Aid Lighting Fixtures for Ship Flight Decks and Expeditionary Air Field Matting
Abstract:This Phase I investigation seeks to determine the feasibility of developing a VLA landing light capable of withstanding the anticipated increased high-temperature loads of new jet engine technology in the high-shock aircraft carrier environment. The fixture will be a form-fit- function replacement to the legacy fixture but will also explore the possibility of using advanced materials, optics, coatings, light sources and manufacturing methods. The ability to withstand direct jet exhaust up to 1700F will require the development of special sealing and gasketing techniques and the use of metal alloys that will not anneal, harden, or soften under the repeated temperature excursions. Optics and coatings will be developed that can survive for extended periods (thousands of hours) at a sustained 1700F in atmosphere. A detailed design validation plan will ensure that the developed fixture ultimately meets its intended specifications. Small-sample testing will also be performed to validate the performance of the proposed materials and interface methods.

Title:Aeroacoustics of High-Speed Jet Impingement
Abstract:CASCADE Technologies is proposing to use CharLES, its in-house unstructured large eddy simulation technology (LES), to simulate the flow and noise emitted from supersonic impinging jets. This problem is relevant to noise of combat aircrafts designed for Short Takeoff and Vertical landing (STOVL) as well as interaction of propulsive jets with Jet Blast Deflectors (JBD) on an aircraft carrier deck. To demonstrate the prediction capabilities of CharLES, a supersonic jet issuing from nozzle and impinging on a ground plane will be considered in Phase I; LES results will be validated against the experimental measurements of the STOVL supersonic facility at the Florida State University. In addition, a proof of concept LES of JBD interacting with a propulsive high-speed jet will be carried out in Phase I. In the option phase, we will study a heated jet as well as the effect of nozzle distance from the ground. Phase II will focus on further development and demonstration of LES and acoustic prediction tools for impinging jet aeroacoustics with realistic geometry such as twin nozzles, part of airframe, ground plane and jet blast deflector. During this Phase, CASCADE will collaborate with GE on modeling propulsive jet-JBD interaction flow and aeroacoustics.

Title:Aeroacoustics of High-Speed Jet Impingement
Abstract:The noise from the turbulent, hot, supersonic jets at take-offs and landings dominates noise emanating from other powerplant components and has significant safety implications for launch personnel, as well as by the integrity of the structural components of the deck itself. With the impending induction of the JSF/F-35B into the US Navy in the near-future, concerns regarding noise emissions have taken added prominence. Unique to the JSF/F-35B is the requirement for it to operate in short takeoff and vertical landing (STOVL) mode on smaller ships, with the exhaust nozzle being vectored vertically downwards to produce lift. Jet impingement on the deck gives rise to resonant tones that are produced by a powerful acoustic feedback loop formed between the ground plane and trailing edge of the exhaust nozzle via the ambient medium. Similar noise issues also exist with regards to exhaust impingement on the jet blast deflector (JBD) on carriers. CRAFT Tech and Purdue University will extend and demonstrate an innovative high-fidelity LES method towards characterization of the noise sources associated with high-speed impinging jets. The farfield noise emissions will be obtained with integral techniques that will be extended for jet impingement. The model will be validated against laboratory data.

Title:Adaptive, Overset-Mesh Methodology for the Aeroacoustic Prediction of High-Speed Impinging Jets Using Large-Eddy Simulation
Abstract:Impinging supersonic jets can generate intense sound through a resonance phenomena, with tones approaching 15 dB beyond the already-loud baseline noise levels. The source of impinging jet noise, including that created by jet blast deflectors, is broadly the interaction between jet and deflecting plane, which can in certain cases close a resonant feedback loop. Accurate prediction of the noise is necessary for understanding the as-yet unknown detailed source mechanism(s), as well as enabling development of mitigation procedures. We seek to apply our validated LES prediction tool in Phase I to two well-documented cases of under- expanded jets impinging on a ground plane: one case resonates while the other does not. Our objective is to use our existing adjoint-based optimization methodology to highlight flow regions most sensitive to design changes or control strategies to reduce radiated noise. As shown in our previous, validated noise reduction efforts for turbulent jets, the adjoint provides a direct investigation into those areas of the flow, such as at the nozzle exit or ground plane, where a noise reduction strategy can be designed. GE Global Research has confirmed their strong interest in this R&D effort, and has agreed to provide critical guidance and review throughout Phase I.

Title:Localized High Fidelity Aeroacoustics Simulations of High Speed Impinging Jets in Operational Conditions
Abstract:Prediction of the noise from impinging turbulent, hot, supersonic jets from real flight systems in an operational environment is an extremely challenging problem. The broad ranges of both temporal and spatial scales that affect the results make a conventional large eddy simulation impractical. To address this issue, a technique is proposed which makes use of localized high-fidelity simulations, while taking into account the conditions in the wider domain. In this manner, practical solutions for jet impingement problems involving full-scale flight hardware can be obtained.

Title:Low-Cost Total Field Magnetometer based on Optically-Pumped Alkali Atoms
Abstract:Physical Sciences Inc. (PSI) proposes to develop a compact low-cost magnetometer for use in airborne and in-water ASW. The novel sensor will combine optical pumping of alkali atoms with sensitive balanced ratiometric detection and frequency counting electronics. PSI has successfully demonstrated sensitive magnetic field detection using the proposed approach in previous programs. During the proposed Phase I program, PSI will design a sensor measurement head and control unit in a low-cost package with size, weight, and power specifications that meet Navy requirements for use on unmanned aerial vehicles, buoys, and torpedo platforms. Critical electronic subcomponents will be fabricated and demonstrated in Phase I. The compact electronics will be combined with a laboratory measurement head during the Phase I Option program to demonstrate sensitive magnetic field detection. During the subsequent Phase II program, two fully operational prototype magnetometer systems will be fabricated and tested to verify operation and performance under representative measurement conditions. PSI has extensive experience applying its successful line of commercial absorption spectroscopy hardware and software to demonstrate sensitive magnetometers. This expertise will be used to transition the proposed magnetometer to volume manufacturing in Phase III.

Title:Low-Cost Compact Magnetometers for Air and In-Water Anti Submarine Warfare (ASW)
Abstract:Magnetic anomaly detection (MAD) is an important component of anti-submarine warfare. This Phase I SBIR project will investigate a low-cost, high sensitivity sensor for both sea and airborne antisubmarine warfare. We recently demonstrated high sensitivity using magnetometers based on nonlinear magneto-optical rotation of the polarization of a laser as it propagates through an atomic vapor. By adopting less-expensive components it is possible to substantially reduce the cost of the sensor, but this requires changing the operating principles. The performance of critical sub-assemblies will be tested to determine if the magnetic sensitivity is maintained. An estimate of the size, weight, power, performance and cost of a fully engineered device will be made based on the results of the Phase I investigation. In the Phase I Option, a method will be devised and tested for constructing the magnetometer to avoid any dead zone.

Title:A Compact, Low-Cost, Isotropic Atomic Magnetometer
Abstract:Modern atomic magnetometer technology is poised to deliver total magnetic field measurements in a sensor that is dramatically less expensive, smaller, and lower-power relative to currently-available sensor systems. Using a combination of technologies that have emerged recently, we propose to develop a scalar atomic magnetometer with sensitivity of 1 pT/Hz^1/2 featuring suppressed heading error and no dead zone that can meet a cost objective of $2,000 in quantities of 500. Existing magnetic anomaly detection (MAD) for anti- submarine warfare (ASW) is performed by sensors in the unique tail section of the P-3 aircraft. With the retirement of the P-3 and the transition to the new P-8 platform, anti- submarine warfare stands to lose onboard MAD which has traditionally provided an important verification of target location. The low cost of the proposed sensor uniquely enables planners to consider new usage scenarios including UAVs where magnetometers may be lost or destroyed after completing a mission.

Title:Rain Repellency for Shipboard Aircraft Transparency
Abstract:GVD Corporation (GVD) proposes to develop permanent, rain-repellent aircraft canopy coatings based on its novel, solvent-free PTFE (polytetrafluoroethylene) technology. Commercial off-the-shelf rain repellents possess neither the required durability nor the needed uniformity for use on high speed aircraft. In addition to its well-known water-shedding capabilities, PTFE exhibits exceptional chemical resistance and temperature stability, both of which are required for successful canopy coatings. Notably, GVD’s PTFE coatings are also optically-transparent, chemically-pure, and well-adhered, and can be deposited uniformly from the vapor phase. Unlike conventional PTFE coatings, GVD’s PTFE coatings require no post-processing (e.g., high-temperature sintering), and are immediately ready to use. In Phase I, GVD will screen multiple PTFE coating formulations using a series of tests designed to simulate environmental exposure. Promising coatings will be downselected for rain erosion and other advanced testing. The most promising coatings will then be further developed in Phase II with an eye toward coating scale-up and manufacturing.

Title:Durable Rain Repellent Coatings for Aircraft Transparencies
Abstract:Maintaining a high level of visibility in aircraft transparencies and other optical equipment is very difficult under inclement operational conditions. There have been significant efforts in the development of hydrophobic and superhydrophobic coatings that will shed water quickly off of surfaces. Whereas many technologies and coatings have demonstrated the primary goal of achieving watershedding properties, they have lacked mechanical and environmental durability, or have been difficult or expensive to apply. Luna Innovations is developing a class of highly durable watershedding coatings, titled HARSH (Hard Abrasion Resistant Superhydrophobic), which can be achieved through controlled surface morphology. Luna proposes to utilize this transparent, superhydrophobic, abrasion resistant coating developed in our laboratories for use on aircraft windscreens and canopies. The technology developed on this program will decrease life cycle costs, reduce maintenance, and increase the safety of Navy equipment and personnel.

Title:Rain Repellency for Shipboard Aircraft Transparency
Abstract:Navy aircraft often have to taxi, take-off, and land during conditions of differing amounts of rain. While performing taxi and take-off operations the pilot must be able to clearly see ground crew directions. During landing, the pilot must be able to clearly see landing strip lights, and for carrier landings, the Optical Landing System (OLS). As a consequence, maintaining visibility during inclement weather is critical to flight crew operations. This can be a difficult task as aircraft transparency materials are not inherently water repellent and there are no mechanical means of maintaining viability. To address this issue, the Navy is interested in the development of innovative methods to promote water shedding during ground and low speed operations. Under the proposed program, METSS will address this issue by using a proprietary process to permanently treat the surface of existing aircraft transparency topcoat materials with an appropriate level of short chain hydrophobic polymers to create a highly rain repellent surface. The hydrophobic materials will remain permanently anchored into the surface of the topcoat via polymer chain entanglement networks or, alternatively, cross-linked into the polyurethane coating, essentially forming an interpenetrating polymer network (IPN). The significant advantage of the proposed process is that the bulk properties of the aircraft transparency topcoat will not be measurably altered by the surface treatment process as the amount of materials infused into the surface of the topcoat will be quantified at molecular levels. Critical performance testing will be conducted to demonstrate rain repellency while maintaining strict adherence to optical property requirements and service life performance in an aggressive marine aviation environment.

Title:High-Strength Steel Component Inspection for Sustained Stresses Using Magnetic Property Sensing
Abstract:A method for nondestructive measurement, characterization, and mapping of sustained stresses in high-strength steel components, using magnetic stress gages (MSG), is proposed. The goal is to provide a nondestructive inspection (NDI) tool for locating specific areas within the components, where high tensile sustained stresses exist making them susceptible to environmentally assisted cracking. This NDI tool will take advantage of the unique capabilities of model-based stress gages such as scanning MWM-Array sensors. In Phase I, JENTEK will perform measurements with the MSG sensors on two types of coupons (in the Base Effort) and on component samples (in the Option Effort) to determine feasibility of measuring the state and magnitude of sustained stresses in primary aircraft structure steel components. JENTEK will perform measurements in two modes: stationary and scanning, in two orientations. In the stationary mode, we will measure on a coupon to demonstrate sensitivity to various levels of sustained stresses and to determine the correlation between the magnetic permeability and stresses for the selected material. In the scanning mode, we will generate maps revealing the residual stress distribution. This latter mode is to be used ultimately on actual rotorcraft components, particularly at the locations where high tensile sustained stresses are likely.

Title:THERSA, THERMOELASTIC RESIDUAL STRESS ANALYSIS SYSTEM
Abstract:To accurately account for effects of environmentally assisted cracking in the overall structural life, quantitative information on the sustained residual stresses needs to be identified. Current methods for residual stress evaluation lack the required level of quantitative accuracy to permit the prognostics efforts pertaining to hydrogen embrittlement and stress corrosion cracking. This lack of accuracy results in i) inaccurate assessment of structure's susceptibility to premature failure, ii) increased maintenance workloads, iii) reduced fleet readiness, and iv) increased safety risks. To avoid these adverse effects, technologies that can accurately quantify the residual stress on aircraft structural components must be developed. In this SBIR program, Materials Technologies Corporation leverages its extensive IR and optical inspection system R&D experience and proposes THERSA, a Thermoelastic Residual Stress Analysis system, based on a novel quantitative infra-red thermography method for nondestructive evaluation and inspection of metal and composite components using thermoelastic stress analysis. During Phase I research, residual stress quantification methods will be established and methodology will be verified through an extensive experimental program. Once feasibility is demonstrated, Phase II program will culminate with the delivery of a prototype THERSA technology to the US Navy.

Title:Phase-Shifting Interferometric Strained-Stress Analyzer
Abstract:To address the Navy’s need for a nondestructive inspection tool to measure strained stresses in metallic components, Physical Optics Corporation (POC) proposes to develop a new nondestructive Phase-Shifting Interferometric Strained-Stress Analyzer (PISSA) system based on absolute optical phase measurements with an electronic speckle pattern interferometer (ESPI). This system can nondestructively and quantitatively measure the state and magnitude of a sustained stress present in a primary aircraft structure and on complex surfaces to assess susceptibility to environmentally assisted cracking in structural components. The PISSA system will improve flight safety and reduce inspection cycles for aircraft during fleet operations and directly addresses the Navy need for a nondestructive depot-level inspection tool. In Phase I, POC will demonstrate PISSA system feasibility by constructing and testing a laboratory prototype and providing diagnostics to determine the potential for crack initiation resulting from hydrogen embrittlement. In Phase II, POC will refine the system design and develop and demonstrate a full-scale PISSA system that can be effectively implemented in an environment equivalent to that of Fleet Readiness Centers (FRCs) without significantly disrupting the workflow or degrading the reliability of the data.

Abstract:Accurate Automation Corporation (AAC) proposes to provide a source that can meet the requirements of this present solicitation using a technical approach based on recent breakthrough technology that has made it possible to design a scalable fiber optic laser that can operate in all of the low loss windows in the eyesafe NIR band. Based on a technique whereby the fiber core is doped by nanoparticles (NP) containing different rare earth ions, a single fiber can be made to behave as an independent amplifier at multiple signal wavelengths within these windows. Hence, a single wavelength band switchable and wavelength tunable source can meet the Phase I, II and III performance requirements. Moreover, the development of practical HEL sources in the NIR is converging on fiber optic lasers, so having a test source that can operate at all of the candidate eyesafe NIR fiber wavelengths is especially appropriate. High output power will be achieved by combining the output of several fiber amplifiers through a passive coherent combining technique.

Title:Low Cost G-cues for Pilot Training Device
Abstract:Pilots of today’s high performance aircraft must simultaneously process not only the ever- changing visual field outside the cockpit and at the controls, but also the fluctuating gravitational vector and the vibrations of the airframe. Flight simulators are critical in preparing pilots to integrate useful sensory input and ignore extraneous cues without the costs and risks of real flight training. As simulation is an essential component of pilot training, an ideal system would be highly realistic and widely available. Currently several flight simulator systems exist, including various seats and full-motion platforms. However, such products are costly and possess limitations that restrict the simulation’s authenticity. As such, there is no single system on the market that can impart both g-cues and vibration to the entire body. Our unique Dynamic Integrated Simulator Cueing (DISC) Suit integrates g-cues and vibration inputs to the whole body. While it thereby provides a highly realistic experience, the suit is also engineered from materials that keep its overall cost low, and it can be used to augment any and all existing flight simulators. The DISC Suit can consequently serves as an ideal option for training our pilots in a highly effective and low- cost solution.

Title:Exploiting Multipath for Efficient Target Classification
Abstract:The objective of this effort is to develop innovative methods to improve the efficiency and accuracy of Radar Cross Section (RCS) based target classification by exploiting naturally occurring multipath signals. Our goal is to develop a mathematical basis of the multipath exploitation concepts to be incorporated into an analytical model which will be used to prove (or reject) the utility of the approach. We are developing promising approaches incorporating multipath isolation processing and compressive sensing techniques to reconstruct the target’s free-space scattering behavior. In addition, we plan to utilize electromagnetic-based multipath modeling as an integral part of our Phase I research. Ultimately, we will use experimentation, in which live data from a controlled multipath environment is collected and processed off-line to develop the RCS signature of an actual target. The techniques to be developed will provide surveillance and tracking radars, or similar radars, improved RCS based target classification by exploiting naturally occurring multipath. Our focus during this Phase I effort will be on low frequency UHF surveillance radar applications.

Title:Exploiting Multipath for Efficient Target Classification
Abstract:Automatic target recognition(ATR) for tactical military targets is a very challenging problem, particularly when the number of observed aspects of a target is subject to the operational constraints of the sensor platform. When the target is situated in the presence of a complicated background medium, such as in urban or hilly settings, the observed signals might be deformed significantly, thus the classification performance suffers. However, it can be proved that the observed signals of a target in the presence of a complicated environment are linear combination of the target’s scattering fields situated in free space. Thus the target is actually observed from multiple aspects for each such measurement. On the other hand, the angle-dependent target responses are typically a smooth function of aspect angles, and therefore are highly compressible. In this Phase I, the concept of in situ compressive sensing (CS) will be employed to exploit the multipath response. ATR can subsequently be performed with a relatively smaller number of observations within compact aspect range. The target RCS/far fields in free space will be simulated via multilevel fast multipole algorithm (MLFMA), and various random projection matrices will be generated to simulate simple and complicated environments, respectively. Sparse Bayesian classifiers will be used to assess the classification performance and efficiency of CS compared with conventional approaches.

Title:Bistatic Radar Receiver/Processor
Abstract:This multi-phase program will develop an accurate automated passive, single-airborne- platform, non-cooperative emitter geolocation capability which utilizes radar transmissions and leverages knowledge-aided techniques. This capability will include the ability to utilize varied information sources, when available, to determine emitter location coordinates within timelines relevant to real-time mission operation. These information sources include, but are not limited to, operator inputs; a-priori emitter surveys; emitter scan parameters and waveform characteristics; and Digital Terrain Elevation Data (DTED) and Land Use and Land Cover (LULC) databases. We will leverage the results and hardware of our recently completed program which built an airborne prototype system capable of synching to a non- cooperative emitter and processing the bistatic radar returns to track illuminated airborne and surface moving targets passively. This system will be the starting point for this effort, providing the synchronization and clutter map data needed to perform automatic emitter geolocation. In addition previous bistatic geolocation IR&D research will be leveraged. The integrated system would be capable of collecting clutter map data that could be used to, within a period of few minutes or less, locate a circularly-scanning surveillance radar to within 1 km or better by correlating with terrain data.

Title:Nondestructive Determination of Case Depth
Abstract:In order to increase wear resistance, many critical components such as shafts and gears are case hardened. Case hardening, such as induction hardening, carburizing or nitiriding, can create a hard wear-resistant surface layer The depth of the case hardened layer must be controlled to achieve optimum in-service performance of the component. There is currently no reliable nondestructive method of determining case depth. Eddy current offers the potential to provide that capability. JENTEK and others have shown correlations between electromagnetic properties, i.e., conductivity and permeability, and steel microstructure. Also, local electromagnetic properties, measured on a cross section, have been correlated with hardness in case hardened samples. In testing for a major automotive manufacturer, JENTEK has shown a preliminary correlation between case depth and magnetic permeability measured from the external surface. In this proposed Phase I program JENTEK will work with Bell Helicopter, Rolls-Royce and Sikorsky to adapt JENTEK’s Meandering Winding Magnetometer (MWM) and model based inverse methods for nondestructive determination of case depth. The MWM and MWM-Array are thin and conformable eddy current sensors that deliver superior materials characterization performance for challenging applications and have a strong potential to provide an effective tool for case depth measurement.

Title:Hand held Eddy Current Tester for Accurate Depth Measurement of Case Hardening in Aerospace Materials
Abstract:New technology is needed for nondestructive inspection (NDI) of the interface depth on case hardened aerospace components such as gears and drive trains. At this time, the standard method of measurement is destructive and sample dependent - cross sectioning and traverse-hardness testing. An NDI technology capable of measuring the core-to-case interface depth on small, geometrically complex areas to high accuracy would be ideal. Existing NDI technologies such as coil eddy current testing are still in the laboratory stage, and are limited to measuring large, homogeneous samples because of the size of coils required for sensitivity. RMD proposes a revolutionary new eddy current technology it has recently patented based on using a microscopic, high sensitivity, solid state AMR sensing element to measure the case hardening interface depth. The 2-D solid-state sensor will allow miniaturizing of the ECT probe so that it can be used on small geometries with accurate results. The proposed NDI system will be portable, versatile, and simple to operate. Through making possible 100% testing of components during fabrication as well as in- the-field testing, the proposed NDI technology will improve aircraft integrity and crew safety, improve readiness, and reduce the cost and complexity of inspections.

Title:Creation of New Robust Liquid Induction Carburization Technology LINCARB for Deep Internal Splines with High Aspect Ratios
Abstract:New, patented highly advanced thermo-chemical processing (LINTERPROCESS™) and heat-treatment (LINHEAT™) technologies were developed by SANOVA to address and solve metal and alloy performance deficiencies. Based on these innovative technologies, SANOVA has designed a treatment process which creates highly durable protective surface layers with strong mechanical properties on outer and inner surfaces of components made from various alloyed, high-strength and corrosion-resistive steels, as well as Ti, Zr and Nb alloys. SANOVA’s LINTERPROCESS™ and LINHEAT™ technologies have a distinct advantage over traditional furnace-based treatment processes due to combination of specially formulated and applied highly effective active media and precise control of treatment parameters, and are able to produce desired microstructure and mechanical properties on the gear teeth and deep internal splines with aspect ratio as high as 5:1 and even higher. LINTERPROCESS™ and LINHEAT™ technologies are unique and highly effective, while simple to implement and maintain, environmentally friendly and cost-efficient. They employ effective high-frequency induction heating and high pressure of the active medium in working chamber to generate highest-quality results in shortest treatment durations.

Title:Improved Gear Carburization Process
Abstract:Carburization of steel alloys is a common practice used to increase the longevity of gear interfaces. By increasing the amount of carbon present in the near surface region of the steel, the hardness of the outer region of the material can be increased while maintaining ductility and toughness within the core of the part. Multiple processes exist for carburizing steel components with gas carburization and vacuum carburization being the most common. Both processes rely on gas circulation to carry carbon to the surface of the work piece. In parts with complex geometry, such as gear teeth or cavities, gas circulation may be restricted which limits the amount of carbon that can be transferred to the workpiece. Therefore, an innovative carburization process is sought that can provide uniform carbon coverage and case hardening depth for parts with complex geometries, such as internal spline gears. In response to Navy SBIR solicitation N102-142, United Protective Technologies, LLC (UPT) proposes the use of a modified plasma assisted chemical vapor deposition technique to provide uniform case hardening depth to parts with complex geometry.

Title:Nondestructive Inspection Technique Capable of Detecting and Characterizing Bridging
Abstract:BERCLI Corp. and partners United Technologies Research Corp. and Marietta NDT Inc. propose an integrated inspection system comprised of custom phased-array probes, self- aligning mechanical fixturing to ensure proper alignment of the probes at all measurement points, a mechanical scanner suitable for use with both manual and automated inspection systems, and an M2M controller that allows the use of advanced phased-array techniques. These advances include flexible probes that conform to contoured surfaces, focal methods for high-resolution imaging and self-adaptive focusing techniques that allow the focal laws to be modified on the fly. The ultimate goal of the project is to deliver a fully integrated, nondestructive inspection (NDI) system for complex structures, including large contoured composite parts with tight radii. The aim of Phase 1 work is to demonstrate the technical feasibility of using advanced phased-array techniques with customized probes to meet the Navy’s specifications for defect detection and sizing, data visualization, and ease of use. For inspection of rotor blades and other composite parts, this requires optimization of the probes and inspection strategy to maximize resolution and maintain consistent resolution throughout the part.

Title:Anomaly Detection in Curved Composites
Abstract:The detection and characterization of strength-reducing features in composite structures such as rotor blades, notably in the H-53 Heavy Lift Helicopter program, is of critical importance to the Navy. Nondestructive inspection of bridging in tight bends of composites in thick sheets of laminates is one area where there is a lack of capability at the right cost. Intelligent Optical Systems (IOS) proposes Anomaly Detection in Curved Composites (ADeCC), based on detecting guided wave ultrasound for detecting and quantifying bridging over relatively large areas to significantly improve quality control of thick composite parts subject to such defects. An affordable, nondestructive tool is proposed using flexible optical fiber transducers for ultrasound collection that will reliably detect bridging in tight radii. The graphite/epoxy and fiberglass/epoxy laminates of geometries and up to 0.75 in. thick will be obtained from the National Composite Center in Kettering, OH for testing in Phase I. The goal is to detect bridging and other materials or obstructions between layers in samples of molded-in metal sections. After demonstration of feasibility, Phase II will focus on delivering a complete single-command operated hardware and software system that includes data analysis, with detection of bridging and a corresponding confidence level metric.

Title:High Corrosion Resistance, Durable, Light Weight Bulkhead/Deck Mounted Hazardous Material Satellite Storage Lockers
Abstract:In an effort to significantly reduce corrosion, maintenance and save weight, the Navy is pursuing development of new Hazardous Material (HM) stowage lockers. There are two types of hazardous material stowage lockers: Flammable Liquid Storage Lockers and Corrosive Liquid Storage lockers. Both are fabricated of steel. In addition to meeting stowage locker requirements, the material selected to fabricate HM cabinets must also meet strict Navy onboard Fire, Smoke and Toxicity (FST) requirements. Steel lockers perform well meeting FST requirements, as well as fire requirements associated with Flammable Liquid Lockers. However, steel corrodes when used as a material for Corrosive Liquid Storage Lockers. In addition, the Navy is investigating lockers specifically designed to store Calcium Hypochlorite. During Phase I, our team will focus on a durable, lightweight and low cost material selection that meets both HM locker requirements and strict shipboard FST requirements. Also under consideration are low cost fabrication processes such as injection molding, extrusion and pultrusion that offer quality products at low cost. If awarded a Phase II, our team will work to conduct FST and liquid stowage locker requirement testing, and apply Phase I work to the fabrication of full scale HM cabinets for prototype testing.

Title:Hazardous Material Satellite Storage Lockers
Abstract:Navy ships require the use of hazardous materials (HM) such as hydraulic fluid, paint, acids, corrosives, etc. for daily operations. Navy safety regulations and HM management procedure (i.e. OPNAVINST 5100.19E and CHRMIP), require designated HM storerooms for bulk storage of flammable and corrosive liquids. These storerooms have dedicated fire protection systems, explosion proof electrical fixtures, and forced ventilation. In order to increase efficiency, NAVSEA approved the use of satellite storage lockers that will be placed in the work centers to store a week supply of daily use HM. The objective of this SBIR effort is to develop satellite storage lockers for the stowage of HM to meet the needs of the Fleet. Such lockers will be designed for high corrosion/fire resistance with excellent durability while satisfying all specified safety and operational requirements for storage lockers. Pacific Engineering Inc. (PEI) has a history of producing fire resistance composite components for Naval ships and submarines. Our composite lockers will be lighter than existing steel lockers that weigh between 60 to 225 pounds. PEI will also design superior protection against corrosions, and fire, smoke and toxicity per DDS 078-1 while meeting shock/vibration loads per MIL-STD-810 and Grade B UNDEX blast shock per MIL- S-901.NAVSEA approved the use of satellite storage lockers, which will be placed in the Ship’s work centers, to store a seven (7) day supply of daily use HM.

Title:Hazardous Material Satellite Storage Lockers
Abstract:U.S. Navy ships require the use of Hazardous Materials (HM) for daily shipboard operations. In order for Ship’s Force to work more efficiently NAVSEA approved the use of satellite storage lockers which are placed in the ship’s work centers, to store a seven day supply of daily use HM. Flammable and corrosive liquid storage lockers are constructed from heavy corrosion prone steel. In addition calcium hypochlorite (CH) is also required for emergency potable water purification. Calcium hypochlorite is currently stowed in modified first-aid lockers which are then mounted to the ship’s bulkheads. The first-aid lockers are constructed of aluminum and due to the oxidizing properties of CH, the lockers deteriorate quickly. The Navy is seeking a lightweight corrosion resistant alternative to aluminum construction for calcium hypochlorite storage lockers, as well as for steel flammable and corrosive liquid storage lockers. This project proposes to develop cost effective, lightweight, corrosion and fire resistant, durable composite satellite storage lockers that will meet all the structural, and environmental exposure design requirements for use onboard Navy ships. The composite lockers will be constructed from composite materials that will meet all Navy design requirements including fire, smoke and toxicity, and all environmental and chemical exposures.

Title:Hazardous Material Satellite Storage Lockers
Abstract:The use of a multi-functional composite material will alleviate the requirements for expensive maintenance or replacement of satellite hazardous material storage lockers on Navy ships without sacrificing excellent fire protection. The composite material storage locker, consisting of a structural material and one or more conditioning materials, will be demonstrated to meet all of the requirements of the National Fire Protection Association Code 30 and MIL-S-901, Grade B. The composite material structural material has been certified for use within the pressure hull of USN submarines. In full production, the composite material storage lockers will be relatively inexpensive because the both the constituent materials and the material consolidation process are inexpensive. The conditioning materials used in the fabrication of the storage locker will be specific to the materials that are to be stored in the lockers. These materials will be demonstrated during the performance of the Phase I Base effort. A prototype composite material satellite hazardous material storage locker will be fabricated as part of the Phase I Base effort and tested as part of the Option effort. The testing will consist of a shock table test and a fire test.

Title:Thermoplastic Composite Lockers for Hazardous Material Storage on Navy Ships
Abstract:Touchstone Research Laboratory, Ltd (Touchstone) is proposing to use a building-block approach to develop an innovative all-composite solution to solve the Calcium Hypochlorite storage locker problem that the Navy is currently facing. An all-composite storage locker will eliminate corrosion maintenance almost entirely, will reduce weight compared to metallic lockers, and can be designed to meet fire and shock requirements. Touchstone proposes utilizing thermoplastic composite materials technology, which, in addition to being lightweight, high in strength, and impact-resistant, offers excellent chemical resistance. Thermoplastic composites, such as Tegris® (made by Milliken & Company), contain polypropylene fibers that reinforce a lower melt temperature polypropylene matrix. Lightweight, high shear strength core materials, such as CFOAM® Carbon Foam (made by Touchstone), may also be utilized in the locker to increase stiffness, minimize weight, and increase fire, smoke and toxicity (FS&T) resistance.

Title:Enabling Netted Sensor Fusion for Anti-Submarine Warfare in Uncertain and Variable Environments
Abstract:Daniel H. Wagner Associates proposes to develop a tool set for object location and classification, and sensor data geo-registration for full distributed platform data fusion and multi-attribute ASW scene generation. The process of accurately locating and identifying tracks and objects using multiple sensors requires that the individual sensor data be properly geo-registered prior to the data fusion, classification, and location refinement processes to avoid false classifications and misidentified threats. Proposed is an innovative method to register multiple sensor data into a high probability scene using a stochastic multi-hypothesis pairwise registration algorithm. The registered data is then post processed using a multi-hypothesis tracker to produce the most likely scenarios. Our approach to advanced geo-registration algorithms to fuse data from multiple platform sensors includes individual sensor performance, multiple attribute, and maximum likelihood optimal assignment. Once a common ASW scene is created we will classify the track with an inferential reasoning engine used to estimate target ID is based on a context dependent Bayesian Network.

Title:Enabling netted sensor fusion for anti-submarine warfare in uncertain and variable environments - MP 60-10
Abstract:This proposal describes an approach for multi-sensor, multi-target SR&G based on theoretically sound Bayesian probability. A key aspect of our approach is employment of a Rao-Blackwell (marginalized) particle filter to "jointly" track all relevant state parameters and their uncertainty. The filter state parameters are sensor biases, navigation, biases, sensing platform kinematics (position and velocity), as well as the state (position, velocity and classification) of tracked targets. Sophisticated filtering algorithms are required since the bias and measurement uncertainties impact the system dynamics in complicated, nonlinear ways: hence, traditional Kalman filters are inappropriate. A particle filter represents an arbitrary state probability distribution and does not require a linear system model. Particle filtering methods are ideal for systems with highly nonlinear dynamics and high levels of uncertainty. Furthermore, particle filters are readily extensible to discrete and categorical parameters such as class labels.A second key innovation is the use of target feature information and classification information as well as kinematic information to perform the track-to-system data association. The MAP association over all particles will feed forward/backward to the joint particle filter to perform joint target/bias tracking.

Title:MOSAIC: Measurement of Simultaneous Actions and Integrated Contexts
Abstract:The U.S. Navy is filled with multi-tasking environments (e.g., Combat Information Center, Unmanned Systems, Naval aviation). Multi-tasking requirements continue to grow over time due to an increase in the number and complexity of mission sets, an unprecedented volume of available information, and the Navy’s initiative to reduce manning requirements for effective cost management. While research on multi-tasking is plentiful, measures generalizable to multiple contexts and domains are lacking. To meet this need, we propose MOSAIC: Measurement Of Simultaneous Actions and Integrated Contexts. The goal of MOSAIC is to develop a system that facilitates rigorous evaluation of multi-tasking performance within human-centered systems. The resulting product will have three components: (1) MOSAIC Framework, a multidisciplinary theoretically-based measurement framework of multi-tasking; (2) MOSAIC Measurement Toolset, a set of validated measurement tools that facilitate a multi-method collection of multi-tasking performance; and (3) MOSAIC Analytics Tool, an analysis tool providing an integrated picture of human multi-tasking performance based on the measures and framework. MOSAIC will provide theoretical underpinnings to relevant measures of multi-tasking performance that are implemented in a set of measurement and analysis tools that can rapidly and consistently identify risks and support decisions on mitigation strategies across a range of Navy environments.

Title:Low-cost Polybenzoxazene Composites for High Performance Shipboard Radomes
Abstract:Radomes are key components of future Air and Missile Defense Radar (AMDR) systems and are aboard almost every surface vessel in the Navy. These structures provide protection for the radar face, but the long-term instability of existing radome materials can interfere with the transmission and reception of radar signals. In particular, changes in temperature, moisture absorption, and incident radiation (RF, UV, IR, etc.) can all induce changes into the radome and thereby decrease the performance of the radar system. The objective of this work is to demonstrate the feasibility of producing radomes using low-cost benzoxazine materials. Benzoxazines exhibit good moisture resistance and thermal stability as compared to the epoxies and vinyl esters currently used in radome construction. The results of this work are expected to provide the Navy with a cost-effective means of improving radome performance, while also extending the operational lifetime of these components.

Title:Develop Radar Radome Materials, Processes and Test Methodology
Abstract:The FIRST RF solution proposed for this Phase I program represents a unique utilization of metallic honeycomb structural cell elements to protect the radar system and optimize the RF and RCS performance of the system. The proposed configuration represents an improvement from conventional cascaded-network impedance surface radome designs by using pickup and retransmit radiators with a layer of transition line sandwiched between them. This offers an additional degree of freedom for wideband matching while preventing problems associated with trapped energy associated with conventional approaches. The selection of specific materials and adhesive systems allow for advanced pulltrusion to be utilized for the lamination, eliminating costly and unstable autoclave runs. Test samples will be fabricated and evaluated for RF transmission, structural integrity and Radar Cross Section (RCS) performance. The hardware demonstration during Phase I will demonstrate not only the viability of the technical approach, but also the lost-cost and manufacturable nature of the FIRST RF techniques by completing the demonstration with the limited budget and schedule constraints of a Phase I SBIR.

CDC projectile/warhead fragment materials include tungsten alloys, Hf/Al, W/Al, Al/Boron, Hf/Zn, Zr/Zn, Zr/Al, or Ta/Al, Mo/Al, and select materials with boron, molybdenum oxide and/or sulfur including some polymer matrix composites indicating the potential for process flexibility. Select geometrical shapes such as 1 inch diameter cylinders/disks with 1 inch thickness will be fabricated using the available 300 ton CDC press and existing die/punch assemblies for initial exploration. Compositions will be optimized in consultation with OSD sponsors to obtain varying densities closer (e.g., 7 g/cc or higher). Appropriate experimental process optimization at much higher compaction pressures (e.g., 50 to 150 tsi) will be developed to obtain projectiles of controlled porosities as an integral part of Phase I, Phase I option and Phase II. Key CDC process optimization, suitable as-pressed higher density parts and /or any other less thermal processing sintering/heat treatment responses, net shaped part quality, microstructural/microchemistry properties, and mechanical properties such as hardness and other strength durability properties at room temperature will be evaluated in Phase I. In Phase II, scaling up, materials/manufacturing of advanced projectiles of desirable geometries for reactive fragment warhead components such as multiple-pressing of several pellets, projectile assemblies, spheroidal shaped warheads etc will be planned and the developed CDC parts after optimum processing conditions. One of the potential collaborators in the proposed SBIR is ATK.

Title:High Power, Broad Band Photonic Crystal Fiber Lasers
Abstract:A high power, broad band fiber laser based on sumpercontinuum generation from photonic crystal fiber was proposed. A picosecond fiber Yb doped MOPA is used as pump source; A small core diameter and high air-fill-fraction in the cladding all silica based photonic crystal fiber with zero dispersion wavelength at ~1020 nm is designed to generate broad band supercontinuum; by adding the fiber mode expanded tips and integrate the in-liner polarizer, the thermal damage effect will be reduced and thus output power and laser system stability can be significantly increased. The proposed fiber laser is able to generate high output power (>50W), higher efficiency and wider spectrum bandwidth (500 to 1800 nm). In Phase I, we will fabricate a proof of concept breadboard fiber laser. Full system demonstration will be realized in the Phase II Program.

Title:Broad Band Fiber Lasers (Wavelength of ~500nm to 1800nm)
Abstract:Broad band coherent sources have a number of applications including countermeasures and free-space communications. SA Photonics' Flash system provides a high power, >50W, broad spectrum solution with beam quality better than three times the diffraction limit. The Flash system uses a robust high repetition rate laser to achieve these results, with a small overall form factor. Further, techniques are employed which mitigate the low SRS and SBS limits set in a number of systems. The laser will be able to run continuously for much greater than 10 minutes with no degradation of beam quality or output power. The Flash system architecture requires minimal maintenance, has a long lifetime, and can be ruggedized for operation in a maritime environment.

Title:Innovative Ship/Aircraft Analytic Securing and Positioning Algorithms
Abstract:On-deck positioning and securing is an essential aspect of rotorcraft shipboard operations. The controlled or restrained on-deck positioning of aircraft is a complicated process that is strongly affected by the unsteady ship motion, the turbulent wind condition, and the aircraft and ship flight deck configurations, such as the type of aircraft, the size of flight deck, etc. This SBIR is dedicated to developing innovative ship/aircraft on-deck dynamics and aerodynamics modeling methods and algorithms in support of effective aircraft on-deck positioning and securing operations. The modeling methods and algorithms under development will overcome the major limitations inherent in the current on-deck analysis tools, including the inability to account for unsteady rotor/airframe aerodynamics and mutual dynamic interaction between the aircraft, the securing equipment, the traverse systems, and the moving ship deck. The advanced analytic tool to be developed aims at improving the design of on-deck tie down and securing devices by considering the unsteady ship/aircraft aerodynamics and dynamics under all environmental and operational conditions. The development will provide the designers of ship, aircraft, and deck securing devices with an advanced tool to effectively design the proper configurations and, hence, facilitate the ship/aircraft integration. The analytic tool will also provide simulation support for rotorcraft/ship dynamic interface analysis and testing, which will enhance ship/aircraft integration test productivity, reduce cost, and increase the safety of test operations.

Title:The Securing Equipment Computation Utility for Response Estimation (SECURE) Toolbox
Abstract:An analysis methodology and associated software toolbox is proposed for development that models aircraft/ship securing and deck handling loads in the Dynamic Interface (DI) environment. The software is unique in that it adds both enhanced physical modeling and a novel multibody formulation to the complex computational problem of representing the forces and responses of the aircraft and securing equipment during deck capture, landing and securing operations. The physics models include proper rotor system and fuselage/gear aeromechanical response to ship airwake disturbances and partial ground effects; the multibody formulation uses a unique methodology that results in a reduced number of parameters, thus permitting a wide class of securing systems and constraints to be simulated in real-time; and the toolbox interface provides a 3D interactive environment that allows for user construction of the simulation environment and an immersive mechanism for viewing computational results. The simulation toolbox, hosted under the MATLAB environment, will be validated using data from dynamically scaled models of both rotorcraft and securing systems, tested on an actual ship deck as part of the Phase I program.

Title:Near Field Passive Tracking
Abstract:Over the last decade developments in ASW sensor systems has greatly increased the number and quality of the sensor systems deployed thus increasing the volume of data to be assessed by orders of magnitude. Sonobuoys as acoustic sensors provide the unique quality of being an in-situ sensor in remote environments. Processing of sonobuoy data also presents unique challenges not encountered on more advanced sensors, and this processing has proven resistant to automation. This notwithstanding, the tactical need for remote sensors such as sonobuoys has only grown. New approaches are needed which address the core issues which throttle process automation. The techniques listed in this proposal addresses fundamental issues which have long limited progress in automation of sonobuoy data processing.

Title:High power density power supply for next-generation radar applications utilizing emerging wide-bandap semiconductor devices
Abstract:Present high power density Si-based systems are severely limited by the electrical and thermal performance of active and passive components as well as electronics packaging technology. As a result, the next-generation of radar power supply systems require a new and revolutionary power electronics technology that delivers far superior efficiency, response time, thermal performance, and miniaturization capability. This Small Business Innovation Research project seeks to develop high-voltage (up to 1000 VDC), highly efficient (>90%), and compact (>200 W/in3) next-generation radar power supplies utilizing emerging Wide Band-Gap (WBG) power devices in conjunction with advanced non-linear control and high power density packaging techniques. The new WBG-based radar power supply technology will be capable of fast response time (rise and settling times < 10 µs) and reducing the output stored energy to less than 1 Joule.

Title:Innovative materials/manufacturing for a prototype 600-1000VDC DC/DC Converter for Shipboard Radar
Abstract:Future Navy Active Electronically Steered Array (AESA) radar systems demand higher peak and average power levels requiring development of high power density, isolated DC/DC converters for pulsed current loads. The Navy requires an advanced DC/DC converter design compatible with Transmit/Receive (T/R) Modules utilized in Navy AESA radar systems and compatible with shipboard power requirements. The power systems within AESA radar systems consume significant power, space and thermal management resources. During Phase I, we will identify, model, and develop an innovative converter design incorporating materials, technologies, and manufacturing processes that significantly improve performance and reliability. CME will evaluate components, perform simulations, develop a detailed design, and conduct proof of concept experiments. Our proposal provides specific design approach to the development of the converter to be initiated during Phase I. The objective is a high efficiency, high power density, low noise, 2.5 kW DC/DC converter for insertion into developing Air and Missile Defense Radar (AMDR) systems. Based on the Phase I design and any improvements in materials, technologies, and manufacturing processes developed, we will be ready to build and test a prototype DC/DC converter to support a Navy transition.

Title:Innovative materials/manufacturing for a prototype 600-1000VDC DC/DC Converter for Shipboard Radar
Abstract:The limiting technology for solid-state phased-array radars has been the RF transmit/receive (T/R) modules. As these become mature, a critical supporting technology is the power supply. Subarrays of T/R modules require a power supply that converts an unregulated DC input at 650 V to 28 V with a peak power of 2.5 kW and 30% duty. The supply must have a power density of over 200 W/in3 and efficiency greater than 90%. Such a converter does not currently exist. In this SBIR, DTI proposes to develop a new converter that is substantially more compact and efficient than is available at present. Achieving a high power density requires operation at a high frequency to minimize the size of the capacitors, transformers, and inductors. The trade-off, however, is that the losses – switching losses in the transistors and magnetic core losses – increase with frequency. To minimize these losses and permit operation at high frequency, the converter will be based on state-of-the-art field-effect transistors. These transistors will have low losses because of their fast switching speeds, produced by an innovative gate drive previously developed by DTI.

Title:Multi-level Analysis and Fusion for Under Sea Threat Assessment (MAFUSTA)
Abstract:Officers responsible for anti-submarine (ASW) warfare rely heavily on acoustic sensors to perceive conditions in their area of responsibility (AOR). Current systems require watchstanders to interpret manually the spatial and temporal relationships among contacts, to construct a tactical picture, infer the contacts’ intentions, and assess the threat that each contact poses. The ASW Commander (ASWC) is often required to make time-critical decisions under rapidly evolving conditions and based on (1) brief or intermittent threat detections; (2) detections and track information from disparate types of sensors; (3) ambiguous classification and localization clues; and (4) difficulty in discriminating threat submarines from non-threat contacts in a cluttered and ever-changing tactical picture. We propose a Multi-level Analysis and Fusion for Under Sea Threat Assessment (MAFUSTA) system that analyzes data from multiple sources, and for each contact, answers the following questions: (1) What is the contact? (2) Where is the contact? (3) What is the contact doing? (4) What, if any, threat is posed by the contact? The system then displays the salient information in a way that enables the ASWC to make rapid but correct decisions about ASW threats.

Title:Collaborative Anti-Submarine Warfare (ASW) Threat Assessment
Abstract:In this project, Wagner Associates, with George Mason University and DDL OMNI as subcontractors, will develop the ASW Threat Prioritization System (ATPS). This system will: I. Prioritize targets based on threat potential, combining• Direct Classification Evidence (e.g. feature measurement clues) and • Indirect Classification Evidence (e.g. tactical events and relationship clues).II. Reduce the time to make threat contact engagement decisions. In order to achieve Goal I, we will combine the classification/identification capabilities of Wagner’s Bayesian Inference Engine with the inter-entity reasoning capabilities of GMU’s Multi-Entity Bayesian Networks and Probabilistic Ontologies. This Level 2/3 Data Fusion functionality will be built on top of the existing Level 1 Fusion algorithms (agent-based simulation, Bayesian statistical, and non-Gaussian optimization) currently implemented in the Undersea Warfare Decision Support System (USW-DSS) Data Fusion Engine (DFEN) and Mission Optimization Configuration Item (MOCI).Achieving Goal II requires extracting the knowledge within ATPS and presenting it to the operator in a way that improves his performance. It is critical that the operator be able to “see” into the ATPS reasoning. The criteria used by the system for promoting contacts to a “threat warning” level will require careful development to avoid a system with excessive false alarms.

Title:Towed Array Fishing Net Entanglement Prevention or Damage Reduction
Abstract:Fishing gear continues to become entangled in underwater towed array surveillance equipment causing a variety of damage to the arrays and towing equipment. Adaptive Methods proposes two solutions which should significantly reduce this damage, fishing gear deflection and fishing gear penetration (cutting). The fishing gear deflection concept consists of a bar or bars attached to the tow/leader cable which will deflect the fishing gear down and away from the areas on the towing equipment where nets or other fishing gear become entangled. The deflection bars will have a hard outer surface to resist penetration by hooks and other sharp objects. This concept is low cost and will have a minimum impact to the array system. The fishing gear penetration concept consists of a long bar with powered cutting teeth designed to cut through fishing gear allowing the arrays to pass through without damage. Upon detection of fishing gear, the system would automatically activate, cut through the gear and shut off. This concept is more sophisticated, and would require more modifications to the array system but would probably better protect the array system. These concepts would be safe for the back deck crew and would not interfere with the array performance.

Title:Fishing Net Entanglement Avoidance
Abstract:To address the Navy’s antisubmarine warfare (ASW) need for a solution that can prevent/mitigate twin-lined array (TL-29A) damage from fishing net entanglement, Physical Optics Corporation (POC) proposes to develop a new Fishing Net Entanglement Avoidance (FiNEA) system. FiNEA is based on an innovative design that utilizes custom and commercial components to detect fishing nets and autonomously perform the necessary maneuvering of the towed array to avoid contact between the towed array and fishing net, thus eliminating the possibility of fishing net entanglement. FiNEA can be easily integrated into SURTASS without requiring any modification and does not interfere with the SURTASS performance. In Phase I, POC will construct a CAD model and functioning prototype to show the feasibility of FiNEA. POC will analyze the research and development required to implement FiNEA, and identify how it addresses the Navy’s current towed array system and system requirements. In Phase II, POC plans to implement the Phase I design in an Engineering Development Model (EDM) and test it in sea. The test results will be incorporated into a full system design, and an improved fully functional prototype will be constructed to demonstrate that it has incorporated the test results.

Title:Integrity and Authentication of Real-Time Data in Navy Combat Systems
Abstract:Existing Information Assurance (IA) technologies in use by the Navy for near real-time and deadline-scheduled data are constrained by significant endpoint dependencies, such as proprietary hardware, pre-shared keys, and administrative configuration. The goal of the proposed project is to provide an enhanced IA suite capable of meeting authentication, integrity, provenance, and confidentiality requirements, particularly for near real-time and deadline scheduled data, in a decentralized, heterogeneous, dynamic-topology publication/subscription architecture, based on the Object Management Group’s Data Distribution Service (DDS) standard. The successful design and implementation of a real- time capable Information Assurance framework for DDS will provide interoperability with key standards required by the Department of Defense's Net Centric Warfare objectives, leverage existing open standards and open source software, and ultimately result in a cost- effective, dual-use commercial product. Achieving this objective will enable secure, authenticated interconnectivity among potentially thousands of publish/subscribe participants, and greatly accelerate achievement of the DoD’s Joint Vision 2020 objectives. Concentris will leverage our experience building publish-subscribe distributed systems, and our current SBIR-funded work on a Distributed Services Framework for DDS, to develop a solution we call TRIADS: Total Real-time Information Assurance for DDS.

Title:Integrity and Authentication of Real-Time Data in Navy Combat Systems
Abstract:Real-Time Innovations (RTI) proposes a set of Information Assurance extensions to the DDS standard and the RTI product that provide the necessary support for Authentication, Access Control, Confidentiality, Integrity, and Non-repudiation for all the real-time data sent over DDS. Our approach will enforce Mandatory Access Control (MAC) on all applications that join a DDS Global Data-Space, requiring them to be authenticated and have the necessary credentials. Beyond access to the DDS Global Data Space, our approach will provide fine-grain Role-Based (or more generally, policy-based) Access Control (RBAC) to specific DDS Topics and even to specific fields within DDS Topics. It will ensure confidentiality of the information (via encryption), integrity, pedigree, and non-repudiation (via digital signatures). Finally, we are proposing key innovations in the area of publish- subscribe one-to-many (multicast) distribution of encrypted information; these innovations will be critical to maintain the real-time QoS in the distribution of information to multiple subscribers. The proposed Security Architecture will be configurable via newly added QoS polices, while remaining open and extensible via “plug-in” APIs so that Navy or Navy Primes can integrate with pre-existing Identity Management Mechanisms, Access Control Policy repositories, or cryptographic libraries which might be program or project specific.

Title:Light High-Speed Tracked Amphibious Vehicle
Abstract:Fast Track Amphibian has made a key breakthrough that allows amphibious vehicles to use rubber tracks to provide propulsion during water-mode operations. Without the need to switch drive trains, extremely rapid transitions between water and land-mode operation are now possible, and the weight of the second drive train is eliminated. We have built a 1/5th scale- model and an 18’ manned testbed, the FT1 to research and develop the technology, as well as demonstrating the capability for high-speed operations on land and in the water. In Phase I, we propose to take advantage of these existing platforms by instrumenting them to collect performance data. This data will be used to refine the analytical methodology used to predict vehicle performance. Research testing will also be performed to improving propulsive efficiency of the track. From this, we will characterize a mid-size vehicle that meets the Navy’s stated 1-ton requirement. We propose two alternate options to follow-on the Phase I effort that prepare for a Phase II demonstrator: alternate 1 prepares for enhancing the sub- scale FT1, while alternate 2 prepares for a full-scale development model.

Title:ABIDE: Agent Based Intelligent Decluttering Enhancements
Abstract:The Anti-Submarine Warfare Commander (ASWC) has a crucial responsibility to protect against surface and subsurface threats, which requires keeping track of contacts and making safety-critical decisions. The Undersea Warfare Decision Support System (USW- DSS) supports the ASWC and his team by providing a “Common Tactical Picture” via the Master Tactical Plot (MTP). However, evolving sensor and data fusion capabilities have resulted in a cluttered MTP requiring more time for ASWC decision making. ABIDE, Agent Based Intelligent Decluttering Enhancements, offers an innovative solution that will dynamically adjust the MTP based on the needs of the ASWC. Two key elements form the basis of our approach. The first is an agent framework that allows for flexibility through the addition and augmentation of agents to meet current and future requirements. The is a scientifically grounded strategy for defining, measuring, and refining displays to reduce clutter . Our solution will be designed specifically for use with the USW-DSS Build 3 common architecture for all applications to ensure that our work is compatible with the larger program.

Title:Service for Adaptive Rendering Through Intelligent Situation Assessment Techniques (ARTIST)
Abstract:Anti-Submarine Warfare (ASW) is a vital strategic concern, as adversary submarines can pose considerable danger to U.S. forces and seaborne lines of communication. The undersea environment is complex and variable, and provides advantages to ASW threats. While relevant surface pictures can emerge rapidly, ASW threat information is often intermittent and ambiguous. ASW Commanders (ASWCs) must incorporate both incoming information and meta-information—qualifiers related to contact data, such as ambiguity, timeliness, or localization uncertainty—to maintain the awareness needed to detect and react to easily overlooked ASW threats. Providing better displays requires not only enhancing existing contact visualizations/plots based on a model of the ASWC’s decision process, but also including more advanced displays for visualizing complex information essential to this decision process. To address these requirements, we propose to design and demonstrate the feasibility of a service for Adaptive Rendering Through Intelligent Situation Assessment Techniques (ARTIST). ARTIST uses agent-based reasoning models of the expert ASWC decision process to adaptively drive the display and filtering of essential information and meta-information. Our approach incorporates enhanced contact displays—within the constraints of existing displays—and new, innovative displays for visualizing complex information not currently available to ASWCs but nevertheless essential in their decision process.

Title:Consolidated Apertures with Co-site Interference Reduction in the Frequency Range 2 to 30 MHz
Abstract:Electromagnetic Interference (EMI) is a major concern for all types of communications systems. Cosite EMI, in which collocated systems are the primary source of EMI, demands much consideration because of the high power levels received due to low isolation between the transmit and receive antennas. To compound the problem, there is also a severe lack of available topside real estate on Navy ships. This not only inhibits the possibility of relocating antennas to optimize isolation, but also drives the need for decreasing the number of antennas required for communications. The Radio Frequency Distribution System (RFDS) designed for operating in the High Frequency (HF) band with limited isolation and fewer antennas also aims to increase communications capabilities.

Title:Consolidated Apertures with Co-site Interference Reduction in the Frequency Range 2 to 30 MHz
Abstract:Zeger-Abrams Inc. (ZA) proposes the use of active feedback cancellation in both the shipboard HF (2-30 MHz) transmitter and receiver systems for cosite interference suppression. The proposed approach supplements consolidation of multiple HF transmit (TX) signals onto two existing TX antennas, and multiple HF receivers fed from one existing receive (RX) antenna. ZA’s approach allows for RX sensitivity down the level limited by external quasiminimum noise and intermodulation products produced by “rusty bolts” in the topside ship structure when multiple high-power HF signals are being transmitted. TX output insertion loss will be greatly reduced from that in present systems. System changes required because of changes in TX or RX frequencies will automatically be rapidly accommodated.

Title:Valve Stem Isolation (VSI)
Abstract:Currently the United States Navy fleet consists of thousands of valves per ship. Carriers can have up to 10,000 valves. The valves require routine maintenance to prevent failures that could lead to catastrophes.. Valves typically fail when the packing gland is compromised. This can happen when fluids slowly corrode the stem and cause leaks. The packing gland can be tightened to stop leaks but eventually the valve requires maintenance. Maintenance consists of removing the verdigris from the components, honing each component to like new condition, and replacing the packing gland. Mide has an innovative concept to prevent corrosive fluids from corroding the valve stem and packing gland. Mide proposes to use a rolling diaphragm to prevent fluids from entering the valve stem. Mide’s Valve Stem Isolation design will prevent fluids from entering the valve stem and prolong the life of a valve. A rolling diaphragm will be inserted between the stem and gate and secured at the perimeter of the valve body. By accomplishing this, Mide will increase the life of the valve and increase the time between routine maintenance.

Title:Low Maintenance, Low Cost Valves: Laser Cured Nano-Structured Protective Valve Coatings
Abstract:Visotek proposes to obviate the need for valve stem maintenance while simultaneously reducing associated manhours, and increasing readiness by refining and adapting a nano- structured protective and low friction polymer coating that is chemically bonded to the valve substrate by a high powered diode laser beam. This bonded polymer layer seals the surface of a substrate from corrosive media by the inhibiting action of nano-sized materials included in polymer matrix. The proposed coating deposition will be a flexible, fast, and reliable process that does not require any changes in current valve design such as substrate material or tolerances between components. The deposited layer has the ancillary benefit of greatly reducing friction in assemblies. In previous field testing the Visotek coating showed exceptional adhesion and corrosion resistance improvement by successfully protecting gas refinery waste water pump plungers. The working medium for these plungers is a very aggressive mix of acids, hydrogen sulphide, particulate slurry and water. The Visotek coating achieved a five times longer seal operating life and fifty times longer plunger operating life.

Title:An Energy-Efficient, Ventless Tumbler-Dryer
Abstract:Navy ships need improved laundry dryers that use less energy and operate without air vents. This eliminates the need for very long exhaust ductwork and reduces fire hazards. We propose to develop a reliable, compact, tumble dryer that employs an innovative water separation process that is energy-efficient and does not require an exhaust vent. The water removed in this process is in the liquid phase and thus can be easily drained away, eliminating the need for an air vent. The proposed dryer uses less than half the energy consumed by a conventional dryer. In Phase I, we will prove feasibility by demonstrating the efficient operation of the water separation system, obtaining data to show its water removal rate and power consumption, and designing a ventless dryer prototype. In Phase II, we will build, demonstrate, and deliver a complete prototype ventless dryer to the Navy.

Title:Advanced Recirculation Tumble Dryer
Abstract:Navy shipboard laundry dryers are major sources of shipboard fires because lint can ignite in the exhaust ductwork. Existing ductless tumble dryers are low capacity and energy- inefficient. To address the Navy’s need for an energy-efficient, fire-safe, and ductless tumbler dryer, Physical Optics Corporation (POC) proposes to develop a new Advanced Recirculation Tumble Dryer (ART-Dryer). This proposed machine will be an upgrade of the existing military tumbler-dryer, based on the unique integration of existing technologies in a new design. This innovation in condenser and heater design will enable the ART-Dryer to increase the drying rate and extract water without cooling the entire airflow. As a result, this technology reduces the temperature in the tumbler with significantly improved drying (~30%) and energy efficiency (~40%), and completely eliminates any ductwork, which addresses the NAVSUP requirements for novel shipboard clothes dryers. In Phase I, POC will demonstrate the feasibility of the ART-Dryer by computer-aided modeling and building of a conceptual prototype to determine its ability to meet all Navy requirements. In Phase II, POC plans to collaborate with the prime, EDCO Corp., to develop an ART-Dryer prototype for operational testing and evaluation at the production site with subsequent shipboard trials arranged by the Navy.

Title:Shipboard Clothes Dryers, “Green Technology”
Abstract:SW Enterprises, LLC has proven its drying technology to the commercial laundry industry. This technology is currently used in a commercial 75# drying system and dries laundry in industry standard times, while requiring no venting and producing less lint. The AdvanceDry75, using this patented heat pump technology, provides warm, dry air to the drying drum by taking the exhaust air, dehumidifying it and reheating it. Using standard components, including a PLC, coil pack, heat plates, and a compressor, this system is adaptable to many sizes and configurations. This proposal is to adapt this technology into a system that will operate aboard a ship in a modular configuration.

Title:High Strength, Optical Quality Spinel
Abstract:Optical quality polycrystalline spinel (MgAl2O4) has been sought as a visible- and infrared- transmitting material since the 1960s because of its potential for transparent armor and durable sensor window. Recently, there have been great strides in the processing of transparent spinel that has shown great promise in optical clarity, however, the improvements in strength of spinel has not been as successful. CeraNova proposes a method to produce a very fine grained transparent spinel in an economic manner that has proven advantageous to increase strengths by multiples in similar materials while maintaining optical clarity.

Abstract:This SBIR Phase I projects will develop magnesium aluminate spinel (MgAl2O4, referred as spinel from here forth) windows with strength of 350 MPa and Weibull modulus higher than 6. To produce the spinel with the strength of 350 MPa, the microstructure of the spinel will be tailored by controlling the processing parameters, such as impurities of spinel powder, agglomerates in spinel powder, amount and types of the sintering aid, and sintering time and temperature. The spinel windows with little residual flux, from the sintering aid or impurities of spinel powder, and no residual strain will be developed.

Title:High Strength Spinel Sensor Windows
Abstract:The Optical Ceramics Division of TA&T proposes to develop fine grained, high strength transparent magnesium aluminate (Spinel) windows for Navy airborne and ship electro- optical sensor hardware A systematic approach based on the latest scientific principles for selecting nano-particulate additives (dopants) that promote grain boundary pinning and retard grain growth is outlined. The approach builds on (1) the recent results of high resolution aberration corrected transmission electron microscopy of doped alumina and the relationship it established between processing conditions and grain boundary atomic structure and (2) the processing know how that TA&T has developed in producing transparent spinel optical windows as large as 11” x 18” and transparent armor windows as large as 15” x 20”. Feedback from optical measurements and microstructural characterization will be used to focus iterative experiments on the nano-particulate dopants, dopant concentrations and processing conditions that appear most promising. Microhardness, fracture toughness, biaxial flexure (tensile) strength and total forward integrated scatter measurements will be made on selected nano-composite spinel samples in order to develop correlations that lead to optimization of processing conditions for scale- up to large size windows in Phase 2.

Abstract:Surmet proposes to scale up its ALON® process for producing high quality window blanks for reconnaissance (Recce) window applications, under this SBIR effort. Surmet routinely produces Recce window quality blanks in 15"x27" size. However, future applications require much larger windows in sizes up to 32"x32". In the proposed Phase I effort, Surmet proposes to scale up its processes to produce half scale windows, 16"x32" in size. Furthermore, these windows will be shown to meet optical requirements for Recce applications. Final scale up to 32"x32" will be achievable through a combination of several ongoing and proposed efforts in conjunction with the Phase II follow on to the proposed Phase I program.

Title:Metrology for Optically Precise Conformal Sensor Window
Abstract:To meet the need of the Navy in fabrication and measurement of conformal windows, such as toroidal made of spinel, to precise optical tolerances, Applied Science Innovations (ASI) proposes development of the improved Asphere Inspection Extreme (AsphInX), building directly on ASI’s successful development of a new tool for metrology on conformal aspheric windows, domes and corrector optics. The proposed improved AsphInX system is a modular attachment for integrating a standard commercial interferometer with an existing optical fabrication tool. The proposed new design will enable measurement of surface shapes of very large and heavy conformal aspheric windows, in a common fabrication process to ensure that the window is finished to specification. Phase I will focus on the design, implementation, and tests of the proposed improved metrology, and on application-specific processing algorithms. In Phase II, the tool will be integrated into a metrology system to be used in production of conformal freeform windows 30 x 30 cm and larger, to reach 50 x 50 cm and larger in Phase III.

Title:Optically Precise Conformal Sensor Window
Abstract:Conformal optics allow for greater versatility in optical design that will give the designer the ability to reduce the number of optics in an assembly and lower the amount of mass and volume required to attain the same optical and functional properties. Currently the design and fabrication of conformal optics are costly due to the difficulties introduced with the fabrication and metrology of these parts. Giving the optical designers realistic constraints for the fabrication of conformal optics is instrumental in developing cost effective systems. Continued improvements in the fabrication and metrology methods will provide a pathway to a more timely process in the production of these optics. OptiPro is well positioned for a successful Phase I effort as they will combine the newly developed “UltraSurf”, 5-axis non- contact metrology system, extensive knowledge of CAD/CAM software and our 5-axis grinding and polishing machines. OptiPro’s technologically advanced fabrication capabilities along with our partnership with the Penn State University Electro Optics Center, the University of Rochester Laboratory for Laser Energetics, and M-Mech Defense (industry experts in piezo-ultrasonic systems) gives us a very strong team and a clear path towards solving the difficult problems associated with grinding and finishing of conformal optics in hard ceramics.

Title:Direct Digital Manufacturing (DDM) of Metallic Components: Controlled Thermal Processing
Abstract:The objective of this Phase I proposal is to demonstrate microstructure modeling and thermal control in order to achieve fatigue properties comparable to wrought material in the Ti-6Al-4V produced by direct digital manufacturing (DDM). The Phase I will begin with selection of a demonstration deposit. A process design will be developed for the deposit by emulating the existing procedure for closed-loop control within the thermo-mechanical process simulation of laser-based DDM. This will provide a measure of non-uniformity of thermal cycling in the deposit. A Ti-6Al-4V microstructure model will be utilized to tailor a thermal cycling path that will result in improved microstructure homogeneity and mechanical properties. The emulation of the closed-loop control will be enhanced to include the thermal cycle induced by the additive material on the previously deposited material. An improved DDM Process Design will be developed in order to match the mean thermal cycling path in the deposit with the path designed using the microstructure model. A fine control of the thermal cycling will be obtained by designing auxiliary devices that act as heat sources or sinks and equalize the thermal cycling. A demonstration deposit will be produced and fatigue testing will be performed on samples located along the direction of deposit and along its two normal directions. During the Phase I Option, the microstructure homogeneity of the deposit will be characterized. In addition, the DDM Process Design procedure will be shown for an electron-beam based DDM process.

Abstract:Stratonics, Inc. proposes to demonstrate the feasibility of measuring critical variable parameters and controlling thermal conditions in direct digital manufacturing (DDM) by developing a multi-sensor/process model-based control system. The innovation combines a multi-view thermal imaging sensor suite, finite element method (FEM) model and real-time software algorithms to control the laser power, deposition position, and powder feed of laser material deposition processes. Stratonics successful development of DDM thermal control will prevent defects/flaws (voids, lack of fusion, porosity because of too cold a process) or inhomogeneous deposits (chemical variation due to excessive melting or vaporization, and variation of microstructure within a part). The imaging sensors will view the melt pool along the laser axis to provide thermal measurements and will also view the deposit from the side. These measurements will be used as input to the FEM process model, which will be accurately calibrated to make intelligent control decisions. DDM System variable parameters will be controlled to produce the required changes in the process to achieve desirable deposit metallurgy. Stratonics has formed a strong team of experts, including Penn and Ohio State Universities and industrial partners, Optomec, Pratt & Whitney and Morris Technologies, all leaders in additive manufacturing technologies.

Title:Advanced ferrite materials for next generation high power microwave (HPM) generation systems
Abstract:Metamagnetics Inc. proposes to leverage its expertise in the development, synthesis and characterization of advanced ferrites for RF, microwave and millimeter-wave applications to identify, analyze and address the ferrite materials challenges pertaining to high power microwave (HPM) generation systems developed in recent years. Measurement techniques that assess the performance of commercially available ferrite materials in HPM applications will be developed during the proposed Phase I effort. These techniques will be utilized to conduct a comprehensive study and identify materials properties responsible for the current limitations in operational capabilities of HPM systems, such as frequency limits of operation, peak power capability, repetition rate, high frequency losses, as well as system size, cost and weight. Theoretical models describing the dynamic saturation processes and magnetic viscosity of ferrite materials under fast rise-time pulse excitations will be developed and predictions compared with experimental data. These experiments will establish a solid foundation for the development of advanced ferrite materials specifically optimized for HPM generation applications in a follow-on Phase II effort. A systematic characterization of ferrite materials in the context of HPM has never been attempted and may prove enabling to the development of next generation systems with enhanced capabilities.

Title:Integrated blade tip lighting system for rotorcraft
Abstract:Aircraft have a variety of lights for collision avoidance and craft-orientation signaling. Rotorcraft are typically affixed with navigation lights on (or near) their main body. This reduces observable distance, and invites obstruction by the body and/or externally-mounted equipment. One obvious solution to is to mount lights at the tip of the rotor’s blades. Synchronizing these lights with respect to the body’s frame of reference creates the illusion of fixed lights. Many approaches have been postulated to accomplish this, but they have not resulted in practical implementations. Diversified Technologies, Inc. (DTI) proposes to build on its existing helicopter blade technology to develop a blade-mounted lighting module which is self powered, and receives information from an off-rotor antenna. In Phase I, DTI (Diversified Technologies, Inc.) will design and realistically test a blade-mounted module, along with the wireless hardware for communicating to it. In Phase II, DTI will further refine its design, and it will test a rugged production-grade article in a spin pit and on an airborne platform. Phase III will be focused on deploying production systems onto a variety of military and civilian crafts, targeting both the retrofit and new-design segments.

Title:Advanced Reference Electrode for Impressed Current Cathodic Protection (ICCP) Systems
Abstract:Unknown amounts of drift in reference cell readings and unforeseen failures of reference cells can disable shipboard Impressed Current Cathodic Protection (ICCP) systems and result in expensive rework and repair. Therefore, the United States Navy has identified the need for robust and reliable reference electrodes for use with shipboard ICCP systems to eliminate nuisance alarms and premature failures. Based on these considerations, Giner, Inc. proposes to design and develop a robust and reliable reference electrode capable of operation in seawater or freshwater, with minimal drift, that could be incorporated into the shipboard ICCP systems. The proposed novel concept will utilize graphite substrates modified with certain metal oxide mixtures in carefully designed ratios, where the novel noble metal oxide will not exceed 2% of the total weight of the graphite. The resulting modified graphite reference electrode will be robust with minimal drift and will be capable of incorporation into shipboard ICCP systems.

Title:Improvement of the Reference Cell for Impressed Current Cathodic Protection
Abstract:Impressed Current Cathodic Protection (ICCP) system is the standard method utilized by the Navy for the corrosion protection of fleet ship hulls in seawater. Long term performance of existing and next generation digital controlled ICCP systems requires a high level of performance from the reference cells. Currently, there is non-optimal operation of the ICCP system due to poor performance of the reference cells. Lynntech proposes the development of reliable, stable advanced reference cells (ARC) by incorporating (i) macro-/micro- structures of the reference material; (ii) simple, cost-effective, non-toxic natural polymeric protective coating; and (iii) self diagnosis tool into digital controlled ICCP system. During the Phase I project, prototype reference cells will be developed and tested, including long term performance evaluation in a laboratory environment simulating Navy operational needs. We will also demonstrate the manufacturability and installation parameters which will lead to consistent, repeatable measurements under realistic conditions. During the Phase II project, ARC prototypes will be designed, fabricated, and tested, and delivered to the Navy. The developed ARC can be applied to a broad range of military and civilian maritime and infrastructure applications where ICCP systems are relied upon for corrosion protection.

The goal of the Phase I work is to build a prototype software and demonstrate its applicability on common mission tasks, such as marching, running, and jumping. This software will utilize state-of-the-art human neck musculoskeletal models combined with whole body level-of-detail models to accurately analyze the muscle and joint forces. To account for fatigue and the onset of potential injury, realistic physiological and physics based muscle fatigue and injury models will be developed and validated. In Phase II, the developed software tool will be used to design an improved helmet system to optimize neck loads over various duration and operational tasks and consequently minimizing fatigue and injury. The final software product will be an easy-to-use and interactive graphics based software tool that can be used by military R&D engineers and acquisition professionals to design and analyze head-supported devices.

Title:Neck Load Simulation During Individual Warfighting Postures and Maneuvers
Abstract:The proposed project focuses on the development of a prototype application to estimate neck load of a dismounted Warfighter engaged in three common mission tasks (i.e. marching, running, and jumping), using an existing verified and validated physics-based computational neck model. In contrast to forward dynamics models (such as that described in (Ryan McCullough)), our physics-based cervical spine finite element model approach includes explicit representations of the head and full cervical column, including all vertebrae, intervertebral discs, ligaments, as well as active muscles, and can compute loads, stresses, and strains in each of these components as well as overall dynamic loading in the neck. Our model has been extensively verified and validated against a suite of quasi-static and dynamic experimental data and has been shown to be highly accurate. By employing a biomechanical component-based approach, where models for each tissue type are treated individually, we not only have a simulation that is more accurate and able to be better validated over a forward dynamics model, but that also results in higher-fidelity simulations able to predict very specific local injuries and overall (global) neck injuries with a high level of accuracy.

Title:An Automated Tool for Predictive Neck Load Simulation During Individual Warfighting Maneuvers
Abstract:As the focus on survivability, injury prevention, armor design, and human centric design increases, more attention must be paid to human modeling, especially with regards to the head and neck, not only for protection against ballistics and impact, but also for biomechanical issues as a result of normal operating conditions. There is a distinct need for an accurate, easy-to-use, modeling and simulation tool that helps design appropriate head gear, including helmet attachments such as night vision equipment and other sensors. Through a balance of advanced research and customer-driven product development, Viz-Tek and the University of Iowa have developed the fundamental capabilities necessary for building a state-of-the-art head-and-neck simulation tool. This tool will provide an intuitive simulation environment, capable of evaluating biomechanical forces on the neck vertebrae, and determining consequent stresses and displacements of the neck muscles. Such a tool can be used to help design equipment through the conduct of tradeoff analysis. When completed, it will provide product designers and analysts with an effective environment for evaluating new designs, modifying existing designs, and analyzing loads placed on the helmet, fit and comfort, protection coverage, and compatibility with other armor configurations in terms of collisions and interference.

Title:Compact Control Module for Short Towed Arrays
Abstract:A Towed Array Control Module (TACM) will be developed to control the configuration of single and multi-line towed arrays by applying the appropriate force vector at the tail end, while reducing drag. The TACM is a streamlined module with some maneuvering ability of its own that can adjust the array’s shape so it remains effective during towing vehicle maneuvers and current shears, as knowing the shape of the array is critical to interpreting its results. The TACM uses buoyancy and hydrodynamic lift, steering and drag forces to position itself and produce the proper tension in the array. Innovative features are an active control system to keep the array in the optimum shape, and position and tension sensors to provide feedback to the control system. An Array Configuration Algorithm will provide the estimated shape of the array to the control system on the towing vehicle to ensure optimum shape of the array. Multi-line arrays (MLTA) can be towed from the same vehicle, as judicious use of the TACMs will enhance performance, facilitate deployment and reduce entanglement. Array gain will be the primary measure used to evaluate the effectiveness of the array configurations that can be achieved using the TACM.

Title:Shape Memory Towed Array Control Module
Abstract:Shape Memory Alloys (SMAs) are ‘smart’ metal alloys (including Nickel-Titanium) that change shape dramatically when heated with electrical current. In wire form, the shape change is a silent, aggressive contraction, and the wire contraction provides usable stroke with very high forces. In fact, SMA has the highest force/weight ratio of any known motor, providing forces up to 350 times the actuator weight. SMA actuators are ideally suited to the operation of control surfaces, where small form factors and very low weight are driving requirements. We propose to develop an SMA driven Towed Array Control Module (SM- TACM) to demonstrate the superior capabilities of SMA devices in Naval applications. The module will employ hydrodynamic lift to control the depth and position of a towed array. The Miga SM-TACM lifting body is designed to be compatible with both buoyant and sinking arrays, and is capable of surface-start on a buoyant array, or vertical (nose-down) start of a negative buoyancy array. Finally, the SM-TACM lifting body acoustic noise will be lower than that of a turbulent, separated drogue system.

Title:Towed Array Control Module (TACM)
Abstract:Progeny Systems teamed with Makai Ocean Engineering will develop a Towed Array Control Module (TACM) which controls the trailing end of short towed arrays using a small module that provides variable buoyancy, variable drag and control surfaces. With this approach depth and tension can be controlled, the trailing end can be prevented from dragging on the sea floor and TACM could yaw to provide control in the horizontal plane. TACM implements an innovative buoyancy engine design that is modular to provide as little or as much buoyancy required depending on the mission and size of the array. TACM is self powered and draws its energy from the water flow which simplifies integration in the operational system. TACM has no pressure vessels and utilizes an advanced composite structure and pressure tolerant electronics to make it as small and light as possible. Shape memory alloys are also included to provide quiet operation of the control surface actuator. A complete dynamic model of the system will be performed utilizing Computational Fluid Dynamics to define the hydrodynamic derivatives and coefficients which are then used to solve the equations of motion in six degrees of freedom.

Title:Demonstration of transition between wing- and thrust-borne flight with the Flexrotor miniature long-range aircraft
Abstract:We envision a class of miniature robotic aircraft dubbed Flexrotors which offer range, endurance, and economy at levels associated with wing-borne flight, together with capability for hover and VTOL. Routine operations of these aircraft will include dynamic transitions between wing- and thrust-borne flight, for launch and retrieval as well as for “hover-and- stare” interludes while underway. We propose to demonstrate transitions in Phase I using Aerovel’s first Flexrotor prototype. In Phase II we would apply our control techniques to a refined long-range Flexrotor, for demonstration of not only transitions, but also precise positioning relative to a small boat in rough conditions.

Title:Advanced Control of Endurance Aircraft Configured for Agile Hover Operations
Abstract:Aircraft with very long endurance and range, but with the ability to perform hover and stare, ship-board recovery, and wind/gust rejection must have special control and dynamics properties that are different than any currently fielded aircraft. Aurora Flight Science will develop Precision Hover Agility (PHA) flight control design methods, and apply them to various configurations developed specifically to meet next-generation Navy needs. Aurora’s vehicle designs and methods take into account the need to provide large disturbance- rejection forces and moments, to detect both vehicle and ship dynamics in new ways, and to track in a predictive manner. Aurora will develop accurate models for a range of aircraft concepts, and test these concepts using advanced flight control methods in relevant gust and ship-deck tracking environments. Thus the Phase I effort will develop and demonstrate a flight control architecture for multi-flight-mode UAVs performing operations requiring precision hover agility. Development will be sufficient to enable Phase II prototype testing, whose set-up will begin during the Phase I option.

The proposed controller architecture will be most appropriate for small rotary-wing VTOL UAVs weighing less than about 70 kg (150 lbs.) and having a hover flight mode in which the rotor(s) primarily produce a lifting force and a forward flight mode where the rotor(s) primarily produce a thrust force.

Title:Advanced Flight Controls for Ultra-agile Small Unmanned Air Vehicles
Abstract:Significant resources are required to ensure precision of flight control laws over the large flight envelope of modern aircraft. This is often compounded, when vehicle parameters change due to payload modifications, system upgrades, and degradation or failure of actuation systems. In the case of a multi-flight-mode aircraft capable of vertical take-off and landing (VTOL) and cruise flight, the vehicle control challenge extends well beyond parameter changes. Although, flight control systems have been successfully designed separately for rotary-wing and fixed-wing application, the conversion phase in which the aircraft operates “in between” helicopter and airplane mode still poses a significant challenge. To close this technological gap, the NextGen team proposes the development of a nonlinear robust (NLR) control framework that utilizes a state predictor capable of emulating the vehicle dynamics in real time. Thus, required fidelity of modeling data, re-study of the algorithm due to payload changes, and risk to the aircraft due to uncertainties within the vehicle’s aerodynamics during conversion can all be significantly reduced. The NextGen team will demonstrate the controller’s expected benefits through a series of simulations in Phase I and flight demonstrations in Phase II using a Spinwing aircraft which is currently developed under NAVY STTR funding.

Title:Fire Simulation and Residual Strength Prediction Tool for Aluminum Ship Structures During and After Fire
Abstract:A fully coupled fire-structure interaction module will be developed and implemented within GEM’s Abaqus Fire Interface Simulator Toolkit (AFIST) for fire response prediction in aluminum ship structures. This enhanced AFIST will be able to characterize a 3D complex geometry where its topology is not in conformation with a rectilinear CFD grid. Given the strong interaction between the local flow environment and the deformed aluminum structure, an immersed boundary method will be implemented within the customized Fire Dynamics Simulator (FDS). A sharp interface characterization of the solid boundary will be created and the mapping of the boundary conditions from the interface to its immersed boundary nodes will be constructed through local interpolation. A kinematic description of the moving boundary will be accomplished via its coupling with Abaqus. GEM has secured commitments for tool validation support from Virginia Tech and application guidance from NGSB and Navy Lab. The multi-faceted feasibility study consists of the implementation of the immersed boundary method in AFIST, verification of the accuracy of the improved coupling method using an existing CFD/Abaqus coupling toolkit, exploration of the effects of structural deformation on the local flow field, and performance of subcomponent level validation using VT’s pool fire data.

Title:Fire Simulation and Residual Strength Prediction Tool for Aluminum Ship Structures During and After Fire
Abstract:A 3D non-linear and rate-dependent constitutive model will be developed and implemented within GEM’s Abaqus Fire Interface Simulator Toolkit (AFIST) to characterize the time-, stress-, and temperature-dependent material response of aluminum alloys. Both the material and geometric non-linearities will be characterized based on Abaqus’ kinematic description, coupled with its user-defined subroutines. The large deformation model will be formulated based on the additive decomposition of the strain rate tensor in elastic, thermal, and viscoplastic parts. To capture the loading and unloading path in an aluminum ship structural component during a fire, a flow rule will be formulated based on a function of the equivalent stress and the deviatoric stress tensor of the temperature field and of a set of internal state variables. Both the steady state and creep test data at coupon level will be collected to quantify the model parameters and the validity of the developed non-linear rate-dependent constitutive model will be examined via its simulation of the transient state tests. A hybrid implicit and explicit integration scheme will be implemented in AFIST to further enhance the solution efficiency and numerical stability. GEM has secured model validation support from VT and application guidance from NGSB and NSWCCD.

ASAP is the most advanced ship survivability simulation in the U.S. Navy. Under development by the Naval Surface Warfare Center (NSWC), Carderock Division, since 1994, ASAP has evolved into a simulation framework for analyzing a wide array of weapon types, including semi-armor-piercing (SAP) warheads, iron bombs, anti-ship cruise missiles, torpedoes, shaped charges, mines, and so forth. ASAP analyzes numerous damage mechanisms, including air blast, mass detonation of munitions, fragment penetration, shaped charge jet penetration, hull whipping, flooding, fire spread, and smoke spread.

Abstract:In this proposal, we will develop and implement general thermal coupling schemes so that thermomechanical structural solvers, specialized fire-dynamics CFD codes and other thermal simulators may be employed in the solution of practical fire mechanics problems of interest to the Navy. This development will enable large-scale and physically accurate simulations of fire, structural degradation due to thermal effects, and fire evolution due to structural failure. The proposed Weidlinger Aluminum Structure Simulation Platform (WASSP) is conceived as an Application Programming Interface (API) which mediates the synchronized transfer of different classes of data between codes. The research that underlies this development is mainly concentrated to developing the appropriate coupling schemes that both respect the numerical performance and stability of the algorithms exchanging data and the realistic physics of the problem, including the orders of magnitude time-scale differences in the evolution of states in different domains.

Abstract:The proposed work concentrates on the development of a Constitutive Models and Residual Strength finite element simulation module that would be one module in an overall coupled framework, with other modules resolving the fire dynamics (growth and spread), the heat transfer across materials, pyrolysis, etc. A successful Phase I of the project will assess and demonstrate the feasibility of the proposed approaches for simulation of aluminum panels, decks and/or components subjected to fire as well as mechanical loads at various strain rates. Two alternative tracks: creep description and classical viscoplasticity framework will be tested for accuracy and efficiency. In conjunction with the Navy, both approaches will be validated against GFI experimental test data. Development of a complete structural assessment module for fire effects and residual strength simulation for aluminum ships during and after fire is contemplated for Phase II.

Title:Development and scale-up of very low-cost, light-weight, flexible solar cells
Abstract:This Phase I SBIR will develop a scaleable ambient atmosphere manufacturing process to make durable flexible inorganic CuSnZnS thin film solar cells. The existing nanomaterial film manufacturing techniques to fabricate thin film solar cells are cumbersome and may not be that cost effective. The vacuum material deposition technique on the other hand, is capital intensive and has high operation cost. The solution to these identified problems could be SISOM’s proprietary “Streaming Process for Electroless Electrochemical Deposition” (SPEED) system. SPEED is an electroless aqueous based, low capital cost, low operational cost system capable of large area discrete or roll-to roll deposition of self-assembled nanomaterial based films directly on rigid or flexible substrates. The objectives of this Phase I research are to demonstrate a CuSnZnS solar cell manufactured on 10 cm x 10 cm area foil with at least 10 sub-cells with efficiency of at least 6% using SISOM’s SPEED system. Achieving these results in Phase I will open a path towards increasing the cell efficiency to 10% in Phase II. Sisom will scale the process up to 12” web roll-to-roll production of CuSnZnS solar cells. The results of Phase II will move Sisom closer to commercializing thin film CuSnZnS solar cells.

Title:Development of roll-roll processed, low-cost, and flexible organic solar cells
Abstract:Solar cells based on organic materials, also called organic photovoltaic cells (OPVs), have attracted broad research interest due to their low-cost, flexibility and light weight. However, OPV technology remains in pre-commercial stage primarily due to the lack of manufacturing process. Despite a lot of improvement in efficiency, limited attention has been dedicated to develop production technologies for low-cost and large-scale manufacturing of OPVs. In addition, the lifetime and stability of OPV cells is still questionable. In this proposal, Solarmer Energy proposes a comprehensive research plan which will deal with the challenges of manufacturing OPVs at low-cost and improving stability. The overall goal of this Phase I research project is to demonstrate the feasibility of roll-to-roll production of flexible OPV cells in ambient environment. It is also a goal of this project to demonstrate OPV cells that are stable under continuous incident light. At the end of the proposed project we will demonstrate a flexible, monolithically integrated OPV module with 10 series cells and total module area of 100 cm2, with module efficiency of 5% and T80 lifetime of at least 500 hours under continuous illumination of 1 Sun.

Title:Ultra-Low-Cost and Stable OPV
Abstract:Bulk heterojunction organic photovoltaics (BHJ OPV) are a promising technology for converting sunlight into electricity because, in principle, they can be manufactured by coating a wide range of substrates by various solutions containing the organic (and inorganic) materials. However, current BHJ OPV formation in the laboratory uses a variety of labor- intensive, non-scalable deposition techniques. Moreover, champion devices are inherently unstable and incorporate materials whose manufacture is prohibitively expensive. In this project, we will use an exceedingly low-cost and scalable technique for the ambient atmosphere manufacture of all the layers of BHJ OPV modules on both glass and flexible transparent substrates, focusing exclusively on an entirely air-stable device architecture. The technology developed herein will allow BHJ OPV to realize its promise of low-cost manufacturing while also delivering sufficient stability and efficiency to enable its adoption by both the military and commercial markets.

Title:Concept and Context Bi-Hierarchical Learning
Abstract:Synthesizing a variety of ideas and algorithms from Machine Learning, Kernel methods, Spectral Graph Theory, Diffusion Geometries, Harmonic Analysis and Signal Processing into a single mathematical framework, we propose a data driven processing toolbox capable of generating bi-hierarchical information organization and prediction (models) essential for analytical data organization. The associated empirical models are also complemented by natural extensions of all quantities measured on the known data to new data. This extension methodology leads to automatic invariant feature or language definitions and to regression and analysis of empirical functions on and off the data. These resulting algorithms yield a powerful system for automatic learning and classification that is essentially data agnostic and requires no specific ab initio knowledge.

Title:DMAGs – Diffusion Map Augmented Grammars for High-Dimensional Data Representation, Analysis, and Visualization
Abstract:The Navy and DOD are faced with the mounting problem of analyzing larger and larger corpora of unstructured data. Petabytes of unstructured data are generated from a slew of Navy initiatives (LIDAR images electro-optical videos, sonar images) that are completely intractable to analyze by hand. Ontologies and clustering approaches have been proposed to organize the data and mine it for structure, but hierarchical representations require a lot of human interaction while clustering methods have trouble finding compositional structures in the data. UtopiaCompression’s (UC) diffusion map augmented grammars (DMAGs) solve these problems by automatically organizing the data into a hierarchy of low-dimensional manifolds. DMAGs capture the contextual relationships between subspaces of the data and can identify patterns that would take operators hours or days to find. DMAGs are learned in a statistically rigorous framework (diffusion geometry + minimax entropy) and capture far more variability than diffusion maps alone. Moreover, DMAGs can be used to analyze, visualize, or classify new data at different levels of abstraction. The DMAG approach streamlines Navy and DOD efforts to find patterns in large high-dimensional datasets and leverages a novel knowledge-based hierarchy to quickly and efficiently represent unstructured data from a multitude of different sources.

Title:RDF Entity and Association Disambiguation (READ)
Abstract:To keep abreast of groups and individuals operating in a particular area, US forces gather vast amounts of intelligence. Extracted from this sea of information are the entities that exist in the data. We have made great leaps in entity extraction technology. The next challenge is to overcome entity ambiguity that remains at the end of this processing pipeline. These entities are typically stored as connected graphs in the Resource Description Framework (RDF). Because of ambiguities associated with entities, these data stores become filled with redundant statements, preventing Warfighters from finding everything known about specific entities rapidly and accurately. To address this shortfall, DAC is partnering with Cobham (formerly SPARTA) to bring together best-of-breed technologies for entity disambiguation. Cobham has developed the SPEAR NLP package that performs entity extraction. SPEAR is an end-to-end capability for automated Level 1 fusion of text-based multi-INT data. We build on SPEAR to provide the RDF Entity and Association Disambiguation (READ) capability. READ will provide Entity and Relationship Co-Reference Resolution, RDF Conflict Identification and Resolution, and improved RDF Schema for Context Storage. These capabilities will provide intelligence analysts the necessary tools to rapidly and accurately obtain all of the necessary information about specific entities.

Title:Process Mining for Entity Association Disambiguation (PMEAD)
Abstract:Knowledge-Based Systems, Inc. (KBSI) proposes to design and demonstrate an innovative “Process Mining for Entity Association Disambiguation” (PMEAD) capability in response to the Navy SBIR solicitation titled “Disambiguation of Entity Association Statements.” PMEAD will employ semi-automated provenance generation and process mining to identify rules which can be used to identify redundant and missing statements within entity association RDF graphs. This will improve the quality, fidelity and utility of large-scale RDF graphs derived from real-world data. The PMEAD approach is based on the premise that entities exhibit unique patterns in their behavior and therefore two entities that exhibit the same behavior can be resolved to the same entity with a high degree of certainty. PMEAD automated provenance generation and data mining approach avoids the traditional manually intensive and time-consuming process of developing a rule base for inferring missing relationships and resolving ambiguous entities.

Title:RDF-F3
Abstract:Navy operators are being inundated with intelligence information, especially text. Better methods and tools are needed to help them identify the mission-relevant "needles" within these information "haystacks." Researchers have made progress using ontologies-- represented as RDF triples--to guide text extraction algorithms and as a reference model for transforming extracted information into RDF triples corresponding to the ontology. One of the major hurdles encountered in this research, however, has been identifying and eliminating redundant statements in the knowledge base. Our goal in this Phase I Project is to design a methodology and architecture for preventing the assertion of redundant RDF statements to knowledge bases based on comparing the lexical semantics of RDF statements with the lexical semantics of text statements and preventing redundant assertions to the knowledge base, based on synonymy. The concept of operations can be simplified to three steps: (1) Find mission-relevant information in text, based on ontology semantics; (2) Format the extracted information and RDF triples as lexicalized; and (3) Filter statements by comparing lexicalized triples to lexicalized text, preventing redundant RDF triples from being asserted to the knowledge base. We call this the RDF Redundancy Find, Format, and Filter process, or RDF-F3.

Title:Disambiguation of Entity Association Statements
Abstract:Existing techniques for level 1 fusion of association statements in large RDF data stores have proven inadequate to the challenge of entity disambiguation from multiple intelligence sources. The resulting entity and association uncertainty causes problems of missed associations, redundant RDF statements that limit scalability, and significant limitations on higher level reasoning algorithms. Numerous researchers have established the need for higher level context in addressing this problem, and while necessary, context alone is not sufficient. We propose to leverage an existing software-based characteristic matcher operating in a context-aware framework by using a simulated annealing algorithm to support level 1 fusion of a large RDF data store. We will develop a capability whose goal is to generate a single connected graph from large RDF that contains no redundant entities and no missed connections. Specifically, the algorithm we propose will address (i) entity uncertainty, (ii) entity information from different knowledge bases that results in a contradiction, (iii) creation of statements regarding an entity in a knowledge base or common feature space that do not contradict existing statements on that entity, and (iv) allows for the deletion of an entity or entity statements without breaking other associations that may refer to that entity. The result will be an algorithm that integrates and connects new RDF-expressed sources while preserving the original data and semantics, allowing the expression of a large data corpus as a single connected graph. The Feasibility Criterion for Phase I will be to measure and show clear progress in RDF statement disambiguation against a data store containing tens of thousands of statements.

Title:Natural Language Dialogue for Supervisory Control of Autonomous Ground Vehicles
Abstract:As unmanned ground vehicles (UGVs) gain prominence in Navy applications and across the DoD, solutions are needed to reduce the human operator’s cognitive workload. Unburdening the human operator from all but the executive UGV control duties allows the human to focus on other duties, and therefore improves the human’s situational awareness. On the other hand, techniques that totally unburden the human operator are impractical, resulting in heavy training burdens and high computational overhead. Even interfaces that allow the human to interact with the UGV in a natural way, through gestures and speech, use such constrained syntaxes that the interface increases the operator’s cognitive workload. To meet the Navy’s needs, Infoscitex (IST) is pleased to propose Unstructured Speech And Gesture Evaluation (USAGE) for Heads-up, Hands-free UGV Control. USAGE contains a robust human- machine interface that allows human operators to control UGVs naturally, without additional cognitive workload, and without reduction in situational awareness.

Title:ENLIV-N: Effective Natural Language Interface for Unmanned Vehicle Navigation
Abstract:Scientific Systems Company, Inc. (SSCI), in collaboration with Spatio Systems LLC and Prof. Bennett at Olin College, proposes to design and implement ENLIV-N, an Effective Natural Language Interface for Vehicle Navigation. This multi-modal user interface will translate natural language directions and gesture commands into vehicle waypoints, and coordinate feedback to the operator via video display and synthesized voice. Language understanding will be provided by Spatio's DUNE system, which uses corpora of real-world directions to train a novel phrase-based parsing approach that is uniquely robust to disfluencies. DUNE automatically augments its vocabulary using tagged databases (currently Flickr), and has been tested successfully on two ground robots and an aerial robot in indoor environments. Dr. Hsiao at SSCI will leverage his Ph.D. dissertation work on language-integrated robotic planning systems to provide multimodal integration and planning for the ENLIV-N system. Olin's vehicle from the DARPA Urban Challenge will serve as the autonomous test platform. Phase I work will focus on adapting DUNE in simulation to a mission of operational relevance, while designing the gesture, vehicle, and planning elements. At the end of Phase II, we will demonstrate our approach by commanding a real-world autonomous ground vehicle with waypoint navigation and obstacle avoidance.

Title:Natural Language Dialogue for Supervisory Control of Autonomous Ground Vehicles
Abstract:Unmanned Ground Vehicles (UGVs) currently deployed on the battlefield are driven with Operator Control Units (e.g., joystick or point-and-click interface), which requires the full attention of an operator. This means the operator cannot concentrate on maintaining situational awareness, security, or other tasks. To reduce the burden on the operator, SoarTech with our partner Southwest Research Institute propose to develop a natural dialogue interface for interacting with UGVs, where an operator can interact with a UGV using speech and gesture. The UGV will be capable of taking high-level commands, engaging in dialogue with the user to ensure that the command is clear and providing feedback to the user during task execution. To accomplish this, we will design a multi-modal Smart Interaction Device (SID) for UGV control, based on proven Intelligent User Interface system that we have used for supervisory control of tactical simulation entities. We will extend this prior work to a new input modality (e.g., pointing gestures) and a new plug-in to interface with SwRI’s UGV. This approach will enable supervisory control of one or more UGVs, and greatly reduce the workload of the UGV operator.

Specifically, it will feature dynamically adjustable autonomy due its ability to explicitly represent goals and use reasoning methods to determine necessary actions when the human commander is busy or has high cognitive load. It will allow robots to understand natural spoken instructions and robustly deal with disfluencies and speech errors that are typical for spontaneous speech, also filling in details for instructions that are not explicitly expressed using integrated planning mechanisms. We will also investigate the utility of additional non-linguistic interface mechanisms such as gestures to support natural language interactions for cases where natural language commands are not possible.

Title:Advanced Refrigerator for Cooling Cryo-Electronics
Abstract:Superconducting electronics have the potential to revolutionize digital communications and to improve real-time situational awareness in the battlefield environment, but must operate at cryogenic temperatures. Commercial cryogenic refrigerators are large, inefficient and are unable to meet typical field requirements. Our approach is to utilize a reverse-Brayton cryocooler that is optimized for operation with cryogenic electronics. In particular, the expansion work of the refrigeration cycle, which occurs at cryogenic temperatures, will be utilized directly to power the cryogenic electronics. This new and innovative feature eliminates the losses associated with (1) transferring the expansion work to ambient temperature where it is typically dissipated and (2) the parasitic heat loads from the electrical leads that bring power to the cryogenic electronics from ambient temperature. The net result is an extremely compact and efficient system. During the Phase I project, we will finalize specifications for the refrigeration system through discussions with DoD representatives, perform trades to optimize the operating conditions, develop a preliminary design of the mechanical and electrical components, and perform analyses to support our design.

Title:Combined electricity production and cryocooling
Abstract:Infinia Technology Corporation (ITC) proposes to develop a free-piston Stirling cryocooler with an innovative electrical power generation scheme that is integral with a low-temperature stage of the cooler itself. This Low Temperature Power Production Module (LTPPM) will enable the power to be generated at temperatures relatively close to the use temperature, significantly reducing the parasitic thermal load due to lead losses that provide power to the low-temperature stage of the cryocooler. In this case, only a small temperature difference on the order of 25°C exists across the leads, compared to over 300°C in conventional systems. ITC’s proposed cryocooler has multiple stages at about 70°K for the 1st stage and 20 to 30°K for the 2nd stage, to support a 4°K 3rd stage temperature.

Title:Artificial Tissue Matrices for Bone Repair
Abstract:This Small Business Innovation Research (SBIR) by Mo-Sci Corporation in collaboration with the Indiana University School of Dentistry (IU) and the Missouri University of Science & Technology (Missouri S&T) proposes to use bioactive glass bone scaffolds for bone repair. The objective is to develop a completely artificial bone substitute material that mimics human bone and can replace long bones, facial bones and skull bones. The new bioactive glass scaffolds are biodegradable and biocompatible and are synergistic with the natural bone tissue regeneration process. The scaffolds are manufactured by selective laser sintering (SLS), to mimic the structure and mechanical properties of normal healthy trabecular bone tissue, and with good capability for vascularization. The bioactive glass scaffolds will be tested if can function as carrier for Bone Morphogenic Protein-2 (BMP-2) and induce bone healing in small animals in Phase I. Mo-Sci Corp. will develop the SLS scaffolds as Intellectual Property, then work with the American Medical Association and the Food and Drug Administration (FDA) to gain the necessary approvals to begin making the SLS bone scaffolds available to greater medical community.

Title:Artificial Tissue Matrices for Bone Repair
Abstract:The injuries to warfighters caused by Improved Explosive Devices and snipers are often associated with significant loss of long and/or maxillofacial bones. Effective treatment and recuperation necessitates the replacement of these missing bone structures. We are developing a device which once implanted into the injury defect will strongly stimulate osteogenesis and ultimately be resorbed and replaced by the patient’s own bone over one to four months, depending on the size of the injury. By stimulating de novo bone formation and filling the defect with the patient’s own bone many of the post operative complications associated with current therapies will be overcome. This treatment is currently being developed for flat bones such as cranium and maxillofacial, however it will also be effective in long bone. In addition the bioactive component of this device can be applied to prosthetics to increase osseointegration to increase both the rate and quality of recovery.

Title:Artificial Tissue Matrices for Bone Repair
Abstract:The motivation for this research project is to develop nanocomposite material for biomimetic bone repair material that meets all the requirements of solicitation N102-179. This project will provide the means to produce an advanced composite of materials with known efficacy to leverage the mechanical and physiological properties of each. Once validated, the material will provide a bone repair scaffold with: fabrication with precise porosity; will be biomimetic; durable and capable of surgical manipulation; non-toxic; resorbable; cost effective; and the system will be able to produce large quantities of material. The goal is to develop an innovative material and for a variety of custom implants for a wide range of military and civilian bone injuries due to trauma and/or disease. The scaffold will be unique in its construction as it combines the nanocomposite structure with an ingrowth promotion material.

Title:AIDEN: Analysis of Intelligence Data for Evidence of Networks
Abstract:The goal of intelligence, surveillance, and reconnaissance (ISR) operations is to provide analysts and warfighters with situational awareness information. ISR enterprise systems store data to support these operations, but large volumes make it difficult to locate information of interest, such as key individuals. Current keyword-search approaches fall short because they fail to capture semantics. Social network analysis (SNA) techniques, including group detection and SNA metric-based classification, have been demonstrated to find valuable information in graphs, such as networks of interest and the roles of individuals in those networks. Current natural language processing (NLP) tools extract entities, themes, and relationships from unstructured text. By combining such NLP tools, information in text- based documents can be converted into a graph. The application of SNA techniques to such graphs has the potential to enable analysts and warfighters to efficiently locate actionable intelligence in ISR enterprise datastores. 21st Century Technologies (21CT) proposes Analysis of Unstructured Data for Evidence of Networks (AIDEN), a tool for locating information of interest in large, diverse data sources. Our Phase 1 work will focus on a proof- of-concept for applying SNA on graphs obtained from NLP, and identification of gaps in state-of-the-art NLP that will need to be overcome.

Title:Generalized Ontology Discovery Enabling Semantic Search (GODESS)
Abstract:A central challenge in the intelligence community is managing and effectively integrating large amounts of disparate information sources for concise presentation of knowledge to an analyst. Currently, the high volume of near-constant incoming intelligence imposes a substantial burden on the analyst to review and digest the raw intelligence, causing analyst overload and fatigue that could lead to missed intelligence. Generalized Ontology Discovery Enabling Semantic Search (GODESS) addresses this urgent need by analyzing the data’s structure and the analyst’s information needs to provide customized, data- and goal-driven knowledge extracted from disparate, multi-modal document stores. GODESS automatically discovers systems of related concepts structured in the data to learn ontologies that are optimal for representing the knowledge encapsulated in the database – relearning them as new data sources become available, making the approach tractable for environments with continuous, high-volume information flow. In addition to automatically optimizing semantic search based on the data, GODESS optimizes on the user, returning a dynamic semantic network that targets the user’s specific search needs, conditioned on their queries and information objectives. The returned network is a granular graph representation of relevant knowledge, fused at the datastore level, capturing semantic distance between entities providing concise, relevant results across disparate datastores.

Title:Elevating Semantic Search by Marrying Social Network and Content Analysis Techniques
Abstract:The military’s ability to exploit streams of heterogeneous information sources has not kept pace with the enterprise’s ability to generate them. In order to make substantial progress in enhancing the warfighters’ situational awareness, new approaches are required to automatically link related information. We propose to develop this capability by tapping the synergy between existing text analysis and Social Network Analysis (SNA) techniques. Our overall approach can be viewed as “pearl-culturing”, in which our system will first utilize an ensemble of existing text analytics tools to identify clusters of strongly related documents. These tools will include (among others) our own proven technology for identifying documents that were either derived from a common information source or provide details regarding the same event. Our system will then employ ontology-based extraction tools to extract entities and relations from these tight clusters (treating them as if they were a single document). This approach will allow us to utilize existing technology to create more complete entity profiles than has been previously possible. Finally, SNA metrics will be used to quantify and qualify the relationships among documents, entities, and concepts. Ultimately this technology will support improved semantic search as well as SNA across the enterprise.

Title:Acoustic Vector Projector Technology
Abstract:Etrema proposes to develop a modified acoustic projector design that provides broad bandwidth, high source level, directional output, high duty cycle, and high reliability in a compact package. The design will target the same acoustic source levels as the baseline Vector Projector with higher duty cycle, lower frequency bandwidth, and a smaller package size. Specific objectives of the effort are: identify specific improvements to the existing Vector Projector to improve source level and duty cycle; develop a notional projector design by performing a trade-off analysis of different projector designs; and, in the Option, develop a proof-of-concept design that demonstrates the performance goals. Technical feasibility of the projector will be demonstrated by using a combination of equivalent circuit-based models and finite element models to develop a design that meets the performance goals. Long-term performance and reliability will be assessed by identifying areas of greatest risk in the design and developing mitigation plans to address them. Etrema plans to partner with Ultra Electronics Ocean Systems in the development of the Vector Projector. Advantages of the proposed work will be an improved design that meets requirements for ASW and CTDCL missions.

We describe here an innovative approach that provides a lower resonant frequency than in the current design and allows greater output through leveraging action. The approach allows the formation of incrementally scanning using beams developed through a modal approach. These beams can exhibit a constant beam width over the band of interest with minimized radiation toward the host vessel and, most importantly, allow significantly reduced power to attain the desired source level.

Title:Acoustic Vector Projector Technology
Abstract:Although the performance of naval systems for Anti-Submarine Warfare and Counter- Torpedo Detection, Classification, and Localization systems are presently adequate for current missions they are limited by the size, power and detection range of the associated sonar transducer arrays. What is required for the emerging missions are approaches that will reduce the volume and weight of present arrays while improving the pulse duration, high power duty cycle reliability and bandwidth with the ease of transmit beam steering. The Phase I approach will identify and model new materials and / or approaches that will produce the desired high power, bandwidth and directional sound transmission at high duty cycle and pulse duration. This baseline will be sufficient for validation in a Phase II program by fabricating and testing viable transducer prototypes and a full transducer array. The Phase I baseline will also be evaluated for any potential shortfalls in the transducer / array selected with special attention on thermal analysis modeling to predict service life, reliability and development risk in addition to establishing a low manufacturing cost. LewTech Company has teamed with Ultra Electronics - UnderSea Sensor Systems, a major supplier of ocean deployed sensors, to enhance the study approach and product commercialization.

Title:Compact, lightweight Autonomous Underwater Vehicle (AUV) with robust navigation and range for riverine reconnaissance
Abstract:The objective of this Phase I SBIR project is to develop an Autonomous Underwater Vehicle (AUV) with integrated sensing system for efficient and accurate spatial sampling for robust navigation, bathymetric SLAM, and current surveys in riverine environments. The proposed AUV system utilizes innovative propulsion, power harvesting, power management, hull design, and energy-efficient planning and control concepts to achieve a compact vehicle with extended upstream range. The system integrates a suite of intelligent mapping, localization, and navigation algorithms to reliably operate in incompletely known riverine environments with intermittent GPS availability. The proposed project addresses the development of a system-level architecture, designs of the physical AUV devices and accompanying algorithms, trade-off analyses, and analytical and simulation-based validation studies to estimate performance capabilities of the proposed system. This will provide a solid foundation for the Phase II effort, which will address the complete hardware and software implementation of the proposed integrated system and extensive experimental validation of the system capabilities. The system design addresses the desirable characteristics of low-cost and compact design, high endurance, extensibility for various mission scenarios, effective control actuators and control algorithms, and effective autonomous mapping capabilities in GPS-intermittent and GPS-denied environments.

Title:AUV for Sustained Riverine and Littoral Assessments
Abstract:The current proposal addresses the design and fabrication of a rapidly deployable, autonomous underwater vehicle (AUV) suitable for operation within littorals and riverine environments. The proposed platform brings together current state of the art technologies in the areas of doppler sonar, power generation, on-board navigation and system optimization. These technologies will be evaluated, collectively modeled and optimized in the Phase I effort to establish a comprehensive prototype design. The overall objectives for the design will be based on Navy requirements and the specific mission and power draw projected for on-board systems over the proposed mission duration. Initial assessment of the requirements indicate that in order to achieve the duration and projected power draw to achieve a robust navigation solution within the GPS denied environment, an additional power generation solution must be employed. The proposed platform incorporates a hydrokinematic power generation technique to periodically recharge the power supply. Power management and navigation will be managed through an intelligent on-board processor that will be used to optimize the various system parameters to achieve the desired mission objectives.

Title:Compact, lightweight Autonomous Underwater Vehicle (AUV) with robust navigation and range for riverine reconnaissance
Abstract:OceanServer proposes to build on our experiences in the commercial marketplace with the existing Iver2-580 AUV, and to build on the Navy-specific attributes that have been developed or are in development to meet Navy requirements already documented for bathymetric survey, current profiling, obstacle detection and identification, and subsequent in-stride data analysis and presentation. The new research will focus on shrinking the physical size of the existing Iver AUV with its organic sensors, improving power generation and management, and more effectively coupling the vehicle to advanced behavioral software methods of improving navigational accuracy and collecting bathymetric and current profiling data. OceanServer has a 4.5” diameter AUV (Iver2-450) that has been operating as a development platform for 18 months. This vehicle is fully functional, but is limited by the availability of sensors small enough for integration. The research will identify sensor attributes and appropriate vendors to collaborate with in developing these required small sensors. We believe this first step can create a vehicle with an appropriate imaging and sensor package that weighs 35 lbs. with minimal technical risk. Our analysis will then identify technologies and methods to reduce the weight of this vehicle to about 25 lbs. As a final step, the phase 1 research will document and analyze further technologies and methods to create a 3.8” diameter AUV (Iver2-380), with minimal but appropriate sensors that will weigh 16-10 lbs.

Title:Compact, lightweight Autonomous Underwater Vehicle (AUV) with robust navigation and range for riverine reconnaissance
Abstract:An on-going need exists for a small lightweight Autonomous Underwater Vehicle capable of traversing, mapping and reporting data for shallow or remote waterways with difficult access. This bathymetry information must be referenced to above-water features such as obstructions, embankments, or waterway shape. SeaLandAire has partnered with BlueView Technologies and Cybernet Systems Corporation to develop a battery-powered miniature UUV with on-board sensing, intelligent navigation and communication capabilities which can operate in currents up to several knots and adapt its performance to achieve maximum range on the order of 50km. Less efficient speeds can also be used to reduce the overall reconnaissance mission duration. The AUV system includes a novel variable-orientation forward looking sonar from BlueView Technologies to provide multi-use functionality without adding volume, weight, or power consumption to the system. The sonar will provide high- resolution horizontal and vertical obstacle avoidance, bottom tracking using optical flow processing to reduce position error accumulation due to current, and Simultaneous Localization and Mapping (SLAM) based on fusion of in situ bathymetry with a priori GIS data. The design is an extension of prior design programs for autonomous or unmanned riverine and station-keeping vehicles.

Title:Scalable Dynamic Matrix Completion for Information Processing and Link Discovery
Abstract:Recent study by Candes et al. proves that that matrix completion is able to recover the missing entries from a surprising small fraction of random known entries if the matrix admits certain properties. The theoretical advance of the matrix recovery fosters a number of applications such as collaborative filtering, machine learning, and high-dimensional data process. In this project, explore Near-Optimal Matrix Completion (NOMC) for information processing and link discovery in the intelligent communication networks and sensor networks. NOMC advocates matrix completions for Intelligent Link Discovery (ILD) and High-dimensional Object Localization and Tracking (HOLT). Matrix completion for ILD is to predict the subcarrier performance quality from a few observed subcarriers, resulting in high quality link for CR/SDR communications. Due to only sparse subcarrier monitor is required for subcarrier quality prediction, ILD greatly reduces the network communication overhead while other approaches require intensive and continuous subcarrier monitor and data fusion. On the other hand, the matrix completion for HOLT can localize a large number of moving objects and sensors by using a small fraction of sensor location information. This essentially reduces the communication overhead for locating the objects while increasing information values for national security.

Title:Mathematical and Computational Framework for Matrix Completion with Nonuniform Sampling in Resource Constrained Environments
Abstract:Matrix completion (MC) concerns the problem of recovering a low rank matrix from a given small fraction of its entries. It is a recurring problem in collaborative filtering, dimensionality reduction, and multi-class learning and has a long history in mathematics. While the general problem of finding the lowest rank matrix satisfying a set of equality constraints is NP-hard, there are quite general settings where it is possible to perfectly recover all of the missing entries of a low-rank matrix by solving a convex optimization problem. One of our team (Recht) has shown how this convex programming heuristic can be used to reconstruct most n x n matrices of rank r from most collections of entries, provided that the number of entries exceeds C n r log2n for some small, positive numerical constant C. This work extended mathematical results from compressive sensing, in particular building upon its geometric ideas. We propose a nine month research program with three lines of investigation: (i) extend current MC approaches to incorporate nonuniform sampling matrices and resource constraints; (ii) implementation of on-line MC algorithms; and (iii) extend current MC approaches to incorporate regularization schemes beyond rank and sparsity.

Title:A Novel and Fast Approach for Scalable Matrix Completion
Abstract:Matrix completion has many applications such as link recovery, data mining, image reconstruction, etc. We propose a novel algorithm to solve the above mentioned matrix completion problem. In particular, we have derived a novel framework to approximate the rank by another function. This novel framework not only leads to state of the art results in reconstructing missing entries in data matrices, it also can be generalized to find missing values in tensor data which is considered to be significantly harder than the matrix case due to the complexity in its structure and which are unable to solve by previous approaches. Moreover, our new framework can easily deal with noisy measurements. We have proven two theorems to provide theoretical guarantees for convergence of solutions. Finally, we also have efficient implementation of our framework. Preliminary comparative studies with several recent algorithms in matrix completion have demonstrated that our algorithm achieves comparable approximation performance of the best algorithm in the literature and yet only requires 1% of the computations. The matrix dimension was several thousands. This means our algorithm is suitable for real-time matrix and tensor completion of large scale applications.

Abstract:Our project addresses the problem of simultaneous achievement of safety, security, and performance. The study we propose will elicit a better understanding of the implicit trade-offs between the three and explore a promising path forward to optimize all three on a modern computer platform. Our approach is an implementation of the ARINC 653 software partitioning standard as our separation kernel, developed using the open source virtualization technology of the Xen hypervisor and a Linux-based privileged domain 0. For the feasibility study of Phase 1, we target a core set of features (an Agile story) encompassing the CPU scheduler as a key part of the separation kernel. This feature set is analyzed using formal methods with the Isabelle proof assistant. Security is evaluated under the rigor of the Common Criteria, while the safety assurance of this approach is evaluated through a rigorous audit under the DO-178B flight certification standard (with an actual FAA Designated Engineering Representative). In addition, performance is assessed through a hybrid HW/SW measurement technique.

Title:Isolation Techniques for Untrusted Software
Abstract:Open source software is built through collaboration and sharing by a large community of programmers and has wide acceptance in industry and government. Open source software provides considerable benefits of cost and technical innovation which can be prohibitive to duplicate. Unfortunately, open source software used in an embedded system could contain hidden malware which could be activated by triggers to the detriment of a warfighter. PRO-telligent proposes isolating untrusted software in guarded virtual machines. The virtual machine guard will be based on recent extrusion detection research which asserts that process activity occurring independent of human activity on the computer/system is suspect. The guard would be designed using virtual machine introspection to make the guard secure and fast. We believe this approach will protect the warfighter against the potential of embedded malware.

Title:Augur
Abstract:History is replete with “intelligence failures” that were not intelligence weaknesses at all, but an inability to "put the pieces together" in time. Quintessentially, the 9/11 attack is an example, but it is merely the one most remembered. Pieces of intelligence were collected, like so many keys in a jar; but, without the validity and contextual issues resolved, the larger situations went unrecognized. Similarly, the validation and analysis of HUMINT reports is largely a manual process, tedious and burdensome, significantly delaying actionable information getting into the hands of the right person. The Navy can’t afford to continue to allow opportunities to be missed and ineffectual decisions to be made. 21st Century Systems, Inc. is pleased to propose to research and develop Augur, an intelligent HUMINT- processing capability. Augur will permit HUMINT collections to be rapidly corroborated and placed into context, creating opportunities and improving decisions through actionable intelligence.

Title:HUMINT Fusion without Coding (HFWC): An Automated HUMINT to Multi-INT Analytic Tool and Scalable Architecture to Support Navy Intelligence Analysts
Abstract:HUMINT includes text based message traffic, other text document sources composed by humans, particularly the free-form prose text of these messages/documents that can be processed to produce information of value, and other human-produced media types (e.g., video, pictures). Harmonia proposes a new tool, called HFWC ¡V HUMINT Fusion without Coding ¡V that allows analysts to design custom fusion workflows without coding or the need for a programmer to code algorithms to exploit collected, processed, and stored information. HFWC introduces a net-centric data store in a certain format that facilitates the transformation from human analysis to machine-processing, thus providing the essential link between HUMINT and fusion with Multi-INT. Harmonia¡¦s solution also allows an analyst to define small reusable analysis apps, which we call iTel apps, for the intelligence community to rapidly disseminate and share new analysis methods to analysts, form a library of them, and automatically execute them to facilitate HUMINT„_Multi-INT Fusion. A facility to create a corporate memory of analysis methods to additionally accelerate the work of all analysts will be included. The final solution will operate in a cross-domain environment to fuse unclassified data with classified data without compromising security.

Title:STAFF: Semantic Targeting and All-source Fusion Framework
Abstract:Modus Operandi proposes the development of a Semantic Targeting and All-source Fusion Framework (STAFF), an innovative, net-centric framework for fusing human intelligence (HUMINT), signals intelligence (SIGINT), full motion video (FMV) and moving target indicator (MTI) data. STAFF leverages text analytics and semantic technologies to identify, extract and model relationships between entities, activities and events depicted in dynamic HUMINT and multi-INT information. These relationships representing the fused information are made available locally and across the enterprise through the Distributed Common Ground System (DCGS) Integration Backbone (DIB). A feature-rich counterinsurgent (COIN) targeting tool is also proposed that uses STAFF web services to produce superior targeting of threats afloat and ashore. STAFF and the targeting tool will significantly reduce intelligence analyst workload and improve tipping and targeting effectiveness within the DCGS-N Program of Record.

Title:Wideband Low-loss Tunable Band-Pass Filter (BPF)
Abstract:The continued frequency spectrum expansion of software defined radio (SDR) applications combined with the need to simultaneously transmit and receive through a common antenna in smaller form-factors, requires the development of dramatically improved tunable band-pass filter technology. These filters must be able to cover the entire frequency band of operation for both current and future SDR applications with minimal insertion loss, handle the transmit output power in a thermally efficient design, and be integrated into a small form-factor drop- in module. To address the problems faced by modern SDR platforms and the short-comings of currently available filtering solutions, Omega Micro Technologies, Inc. (OMT) intends to capitalize upon their expertise in the fields of Low Temperature Co-fired Ceramic (LTCC) substrate design and fabrication, vertical integration techniques, and embedded filter design to develop a broadband, low-loss tunable filter module in partnership with Rockwell Collins. The developed broadband tunable low-loss band-pass filter module will be directly applicable to either lower power transmit applications as well as receiver front-end applications.

Abstract:To address the Navy’s need for an improved, high-performance passband filter, Physical Optics Corporation (POC) proposes to develop a new Software-Defined Radio (SDR) Colocated Agile Bandpass (SCAB) filter. This proposed device is based on a hybrid filter design utilizing MEMS voltage-tunable capacitors, lumped elements, and innovative microstrip designs to cover the large bandwidth. SCAB will consist of three primary components: (1) a lumped element filter that can tune from 20 MHz to 400 MHz; (2) a microstrip filter that can tune from 400 MHz to more than 2 GHz; and (3) a high-speed voltage controller that can communicate with SDR systems, which frequency hop. The innovation in the filter design will enable the device to provide improved bandpass performance. As a result, this device offers large tuning range from 20 MHz to >2 GHz, Q of >10, and low insertion loss of

Title:Spectrum Fragmentation of Networking Waveforms with Distributed Network Control
Abstract:The DataSoft Spectrum Fragmentation of Network Waveforms with Distributed Network solution identifies several candidate approaches for efficiently fragmenting and reconstituting spectrum using adaptive network control for enhanced MANET spectrum flexibility. Our candidate approaches respond to regulations on bandwidth limits and spectrum availability, as well as to local spectrum disturbances. Static fragmentation, Dynamic/Opportunistic fragmentation, and MANET simulations for spectrum reshaping and adaptive net control are developed to synthesize candidate approaches via iterative simulation and refinement. Performance metrics that quantify the technical, risk, complexity, compatibility, and ease of implementation benefits are defined and applied to rank order the candidates. The credibility of our chosen solution is supported by this broad based evaluation criteria used to rank order each candidate approach.

Title:Waveform Agile Radio Paradigm (WARP) for Frequency Opportunism in Tactical MANET
Abstract:Mayflower Communication Company, Inc. (Mayflower) proposes a novel technology, Waveform Agile Radio Paradigm (WARP), to meet the Navy objective, namely, to develop distributed algorithms and protocols for fragmenting single-carrier spectrum in response to spectrum constraints. WARP is an optimal approach to distributed spectrum fragmentation and recovery for frequency opportunism in MANET communication. WARP will be implemented as a cross-layer optimized waveform solution that performs spectrum fragmentation and recovery with minimal signal degradation and low distributed coordination overhead. WARP approach is designed in a waveform-agnostic manner in order to be applicable for a wide variety of waveforms, including SRW and WNW. WARP will greatly enhance the flexibility of such wideband waveforms and can be incorporated in a variety of platforms, including JTRS HMS and GMR platforms. The WARP solution, when proven feasible in the Phase I study for the Navy application, has enormous potential for military and commercial applications. Mayflower will develop a prototype WARP system in Phase I and II, and ensure its commercialization in Phase III and beyond.

Abstract:The proliferation of Unmanned Aerial Systems (UAS) and the fielding of the Joint Tactical Radio System (JTRS) over the last decade have greatly increased deployment of Military Wireless Mobile Ad-hoc Networks (MANETs). These wireless MANETs have tremendous potential to address the continuous demand for increased available bandwidth of real-time battlefield networking and multi-sensor data fusion. In addition, MANETs have evolved considerably over the two decades since their inception and although the technology was confined to DOD applications until recently, it is currently gaining considerable traction in the commercial market with the advent of new wireless standards such as IEEE 802.16e and IEEE 802.22.

Title:Network Manager Capability Enhancement
Abstract:Mobile Ad-hoc Networking is the central concept employed in the JTRS waveforms, especially the WNW waveform. Due to the cross-layered nature of MANETs, the performance of the WNW network is greatly influenced by the network configuration settings (IP subnet schema, radio channel bandwidth, and waveform configuration parameters). Currently for WNW, the network operator makes the all the decisions for network planning and online re-configuration via the JTRS WNW Network Manager software. Considering the complexity of the waveform, there is no guarantee that the decisions made by the operator based on experiences and intuition will lead to optimal performance. Hence the need for an enhanced network management capability for the JWNM that can continually provide timely, optimized and well-evaluated network configuration during mission planning as well as execution. To achieve this, the combined SNT and Telcordia team proposes to build a ‘Simulation Assisted Network-Management Enhancement’ (SANE) module that combines cutting-edge network optimization techniques and high fidelity ‘faster than real-time’ network simulation. In Phase 1 of this effort, we will focus on developing innovative optimization techniques for SANE that use the concept of ‘simulation-assisted’ search for subnet design, spectrum allocation and waveform parameter optimization.

Title:Reactive Planning and Management Architecture for MANET
Abstract:MANET Management to provide efficient on-demand data transportation can tremendously benefit tactical operations. Most current MANET management tools reply heavily on expert intervention to address dynamic nature of MANET. Absence of automatic optimization and reconfiguration for MANET results in stability problem and underutilization of the network resources. We propose a Reactive Planning and Management Architecture for the capability enhancement of MANET manager, which combines the benefits of black-box optimization and design of experiment to automate the network optimization, reconfiguration, and on-line simulation. Our proposed approach is applicable to optimization of many different network elements, which is very difficult by using specialized computations. The proposed solution also utilizes mission information from a network planning stage to improve deployment conditions and provide useful guidance during a MANET life span. A state-of-art network simulator is a part of the solution to find good set of configuration parameters in much shorter duration. Realistic mobile network scenarios are chosen for experimental study in this project. The effort of Phase I and Options will include evaluation and development of the proposed Reactive Planning and Management.

Title:Advanced Reconfigurable Communications Components
Abstract:Exponential growth in cost, schedule, and risk of satellite communications programs is largely attributable to reliance on space-qualified digital ASICs. This trend is driving an industry need for space-qualified reconfigurable hardware solutions and the efficient signal processing “gateware” that can fully exploit them. One of the key signal processing functions needed for a Software Reconfigurable Payload is a flexible and efficient Sampled IF Filter. Escape Communications specializes in configurable and flexible communication architectures and products. Escape has experience developing and implementing efficient flexible signal processing algorithms and developing path-to-flight hardware for Software Reconfigurable Payloads with proven on-orbit success. The goal of Escape’s Phase 1 proposal is to derive the key SIF filter requirements, define candidate signal processing algorithms to meet these requirements, and analyze the algorithm implementation architectures against known SIRF-based payload resources. The Phase 1 Option will define the work plan necessary to implement and demonstrate a flexible Sampled IF Filter on flight or path-to-flight hardware in Phase 2.

Title:Advanced Reconfigurable Communications Components
Abstract:Space Micro will develop an electrically reprogrammable, Radiation Hardened Sampled IF Filter (RH-SIF) for use in space-based reconfigurable RF/microwave SATCOM subsystems. This technology aims to exceed the capability of traditional tunable filter technology. A programmable radio system must have the ability to program the hardware bandwidth. The RH-SIF exceeds the capabilities of active analog filters in terms of linear phase without sacrificing rejection, simple tuning scheme by varying the sample rate, and potential for high dynamic range with lower power consumption. The RH-SIF takes advantage of signal processing concepts used in finite impulse response (FIR) filter design. A radiation hardened sampled IF filter will be designed and manufactured in commercially available CMOS or SiGe ASIC processes.

Title:Advanced Reconfigurable Communications Components
Abstract:Future fielded Naval space communication payloads require a reconfigurable sampling Intermediate Frequency (SIF) filter capability to easily adapt to rapidly changing Navy space communications needs. Our approach for the SIF leverages Trident’s extensive embedded programmable DSP processor heritage using FPGAs to meet these requirements and utilizes our proven avionics digital technology and strong space environmental experience to design a SIF that will support a broad range of legacy narrow and future wide bandwidth space communications systems such as the Mobile User Objective System (MUOS) in addition to having extensibility to other payload systems. Our approach includes immunity to destructive single event latch up (SEL), and total ionizing dose tolerance in the 100 krad (Si) and includes SEU mitigation to allow autonomous recovery from SEU induced bit flips. Furthermore, our approach considers the reliability required for the longer-term space geosynchronous missions and entails a full hardware reliability prediction for our system to support single or multiple string spacecraft implementations. The Phase I effort will complete our SIF design with modeling and simulation used to verify unit and system level performance against Navy space applications with the Phase I option proposed to solidify the SIF Phase II unit build and test approach.

Title:Multipaction Resistant RF Components for Satellites
Abstract:Satellite RF components suffer from an additional design limitation that does not concern their terrestrial counterparts: multipaction, an electron avalanche effect that can reduce performance or permanently damage devices under certain conditions. To avoid the onset of this effect, the traditional options are increasing the component size (more specifically, gap widths) or reducing operating power. Given the cost per weight to deploy satellite systems, both of these options result in exponential increases in the price per watt of transmission. Nokomis proposes to develop technology for multipactor-resistant components, allowing for increased power handling and performance with improved reliability. The key is that the multipactor mitigation technology utilized will allow for this component performance improvement in a smaller form factor device, enabling the realization of industry-wide performance gains.

Title:Active Mitigation of Multipaction Discharge Using Magnetic Isolation Technique
Abstract:Multipaction is one of the most significant limiting factors to the dynamic range and utility of the vacuum-based radio frequency (RF) devices. If not mitigated, multipaction leads to operational impairments or even permanent damage to the exposed components. RadiaBeam Technologies proposes to utilize a magnetic isolation approach to reduce or eliminate multipaction in critical system components. This approach is based on the recent work at Brookhaven National Laboratory and Fermilab to reduce multipaction by applying a tangential magnetic field to the RF surface, thus forcing the emitted electrons to return to the surface before gaining enough energy to stimulate emission of secondary electrons.

Title:Internal Combustion Battery (ICB)
Abstract:The Internal Combustion Battery (ICB) is a new type of fueled-based power source designed for applications in portable electronics. The ICB combusts liquid hydrocarbon fuels to produce heat and generates electrical power by thermoelectric conversion. An initial estimate of the ICB designed for Software Defined Radio (SDR) application shows that a weight reduction of approximately 2.2 times is achievable as compared to Lithium-ion battery. Further design optimization will yield even higher weight savings. The ICB can be configured in two design approaches: a modular design that incorporates miniature COTS components and a chip-scale design that uses planer processing technology. The projected performance of the ICB is about 300 W-hr/Kg (average) or about 2 times higher than the Lithium-ion battery used currently by the Air Force today for the SDR. Increasing the mission duration from 10 hours to 20 hours would lead to a ICB design with 520 W-hr/Kg (average). Due to its small mass, the chip-scale ICB technology would yield energy density over 1000 W-hr/Kg. In the Phase I ISC proposes to develop a baseline ICB system design and conduct detailed designs and analyses of the major components, such as the micro combustor, heat exchanger and thermoelectric generator.

This innovation will yield high-energy and high-power-density Li-ion batteries with long cycling and shelf life, which cannot be equaled by other technologies.

POC also will evaluate the relevant parameters of NOLIMITS using modeling and small subsystems demonstration. In Phase II, POC will finalize Phase I design concept and demonstrate the technology by testing a prototype to show its potential to meet Navy JPEO JTRS needs.

Title:Inertial Accelerometer Using Cold Atom Interferometry
Abstract:To improve targeting accuracy, Submersible Ship Ballistic Nuclear (SSBN) submarine strategic weapon systems depend on high accuracy inertial sensors in order to precisely determine initial launch coordinates in very dynamic environments. These systems require absolute acceleration accuracy better than 1x10-9 g/¡ÔHz (=1 ƒÝGal/¡ÔHz). Conventional accelerometers based on both macro- and micro-scopic (MEMS) spring mass systems struggle to achieve this accuracy and suffer from bias and scale factor stability. To address this fundamental sensor need, Physical Sciences Inc. (PSI) proposes to develop a precision inertial accelerometer based on cold atom interferometry. In phase I PSI will construct a complete design for a single axis accelerometer to be constructed in phase II. This experimental prototype will demonstrate the required 1x10-9 g/¡ÔHz sensitivity while at the same time incorporating enough flexibility to explore the sensor design space sufficiently to establish the key design criteria that can guide the process of incorporating this technology into current military systems.
