Title:Autonomic Logistics Tactical Logistics Data Communcation Network
Abstract:Fortress utilizes its MacroMesh™ technology to create highly dynamic and robust networks with self-forming, self-healing, path-optimizing capabilities that can support thousands of wireless mesh nodes in a highly mobile network. To accomplish this, MacroMesh incorporates both proactive and reactive routing algorithms into a layer 2 meshing protocol that requires less than 5% of the bandwidth for control traffic regardless of the network size. Furthermore, Fortress has implemented FIPS certified Layer 2 AES encryption to protect both the data in transit and the network itself, complying with the various government wireless and security policies. Fortress has implemented these technologies into both wireless infrastructures, such as the ES520. The Fortress ES520 enables organizations to rapidly establish a high-performance wireless mesh network by combining the functions of an access point, switch, wireless bridge and security gateway in a form factor engineered specifically for harsh outdoor environments. The ES520 weighs less than 5 lbs and uses less than 12 watts of power while providing superior performance in distance and throughput. Coupled with industry leading client support, Fortress offers an end-to-end solution that supports robust communications from the vehicle to the Warfighter or first responder under high tempo mobility. Fortress has extensive experience providing tactical wireless solutions that provide broadband quality networking (voice, video and data) in environments where there is little or no centralized control, no available infrastructure and no reliance on aerial relay nodes. Fortress products are currently deployed in many of the world’s most demanding environments. The U.S. Army selected Fortress to protect what is one of today’s largest tactical Wi-Fi installations in Iraq consisting of over 11,000 wireless access points and 8,000 Fortress gateways. The Texas National Guard is relying on next generation “Rapid Response Communications Kits” from Fortress to quickly establish communications in dynamic environments which have no existing infrastructure. Supporting operations in these environments has required an innovative and integrated approach.

Title:Autonomic Logistics Tactical Logistics Data Communcation Network
Abstract:The IEEE 802.15.4 standard specifies a low rate, spread spectrum, wireless sensor networking technology. Many commercial vendors have begun to develop low cost RF transceivers based on this standard, due to its robust, mesh networking capability. Building on this foundation, the ZigBee industry alliance has been working towards dynamic, self-organizing, scalable mesh networking algorithms based on the 802.15.4 transceivers. Leveraging this rapidly emerging commercial technology, Oberon proposes to investigate the use of 802.15.4 standard compliant components to develop autonomic logistics nodes that have the capability for robust, self-organizing, dynamic, scalable communications in a tactical environment. As shall be discussed, the 802.15.4 technology basis is far better suited than 802.11 (Wi-Fi) or 802.16 (Wi-Max) networking technology due to its intrinsic, standards based meshing capability, native low duty cycle synchronization, and superior RF propagation properties. However, opportunities abound to improve an open architecture for node synchronization, node discovery, self- organization, and in-transit visibility of supporting logistics to a central operations vehicle. Oberon proposes to collaborate with researchers from Penn State University’s Department of Supply Chain and Information Systems/ Marine Corps Logistics Education Program to codify specific requirements for the autonomic logistics system, which can leverage advances in commercially based, advanced 802.15.4 transceiver technology.

Title:A Robust, Mobile, Scalable Sensor Networking Communications System
Abstract:On-Ramp Wireless has developing a highly innovative and disruptive new wireless networking technology called Ultra Link Processing (ULP) to address the necessary communications requirements of a wide area mobile networking system. To date, the performance of free spectrum physical layers (PHYs) (e.g., 802.15.4, 802.11x) and proprietary PHY extensions for such networking have not delivered acceptable solutions. This has resulted in fragmented implementations and significant system complexity and cost. A radically different physical layer and modem signal processing architecture is proposed to address flexible networking with superior performance in challenging radio environments and large geographic areas. In particular, the wireless requirements of the Autonomic Logistics program are well satisfied by this technology. Key features include: reliable communication in a urban environment of 2-3 miles in the 2.4 GHz frequency band, a 25-fold advantage in range over existing protocols; highly robust in high multi-path environments and highly jam-resistant; 25x capacity advantage over other protocols due to simultaneous link demodulation enabling thousands of nodes and efficient use of spectrum; and efficient new mesh networking protocol that can support 100s of network hops - link budget edge plus simultaneous signal demodulation, decreasing coordination requirements.

Title:Engineered Controlled Permeability Fibrous Membrane composite with Active Chemical Biological Deactivation Finish and No Melt No Drip F/R Fabric Liner
Abstract:Single Layer Non-Woven Material with desired functionalities of Chemical and Biological, Thermal Protection, Water Repellency, and Durability would be similar to NST funded research material integrated with archaic Activated Carbon Fiber technology. EYT contends a lightweight composite material can be achieved by integrating, adapting functional components with low risk and desired functionalities for Uniform Combat Material. Although Nonwovens provide correct guidance, there are some fundamental issues: Not Quiet, Poor CD Strength, Poor Hand, cannot be Post Treated and do not yield to body movements. Activated Carbon technology is deficient technology for CB protection - absorption of environment pollutant irrespective of CB threat). EYT proposes to develop and demonstrate the following technologies to generate a multi-layer composite that has: o CB Protection through Controlled Air Permeable Fibrous Electro-Spun and Melt Blown Fibrous Membranes o Application and Integration of Reactive Nanoparticle Chemical Treatments for Neutralizing CB Warfare Agents o Bi-Layer no Melt No Drip fabrics for Fire and Thermal Protection o Superhydrophobicity - grafting low surface tension chemicals EYT has teamed with leading academic (UMass, UTK, MIT) and Industrial partners (Polartec, BlackDiamond) for this effort integrating Reactive Nanoparticles for CB Neutralization, controlled airpermeable fibrous membranes and No Melt No Drip F/R fabrics.

Title:Development of Single-Layer Universal Combat Uniform Material
Abstract:A single layer Universal Combat Uniform offering FR, CB, and WR protection would be extremely advantageous on the battlefield allowing for rapid deployment, ease of use and comfort of wear. Nanosyntex’s approach will be to produce a single layered nonwoven fabric via its patented multi-tiered composite technology using high performance inherently FR fibers having excellent flame and thermal resistance on the inner and outer surfaces with a layer of CB protective substrate inserted into the middle of the structure. This unique multi-tiered composite will be hydroentangled via a spunlace process to produce a fabric with good breathability, comfort and hand. The fabric will then be post-treated using NST's proprietary treatments to provide durability and water repellant characteristics. Using this approach, the outside of the fabric can be designed with a tough outer shell offering good thermal, flame and abrasion resistance. The middle layer will consist of a CB protective substrate such as activated carbon, carbon nanotubes or alternate substrate. And the inner layer will be comprised of fibers offering good thermal protection while providing excellent softness and comfort. NST demonstrated the ability to produce this type structure in earlier SBIR work and plans to build on that innovation.

Title:Development of Single-Layer Universal Combat Uniform Material
Abstract:Protective garments such as the current (JSLIST) commonly use double layer construction consisting of outer shell and inner liner that provides CB protection. The ultimate uniform is bulky, heavy and very expensive due to this design. This SBIR offers an integrated single layer lightweight laminate incorporating CB, WR and FR protection. FR protection would be equivalent or better than existing systems. CB protection would be as outlined in the solicitation and water repellence would be augmented. The laminate from this SBIR would be taken forward in to uniform manufacture. The key challenges to providing a universal garment system lie in addressing the major contributing factor to bulk and weight, the CBRN package. This is currently carbon based with the added disadvantage of being time lined in its performance leading to increased cost overall. This SBIR will develop and use unique and novel membrane laminates to replace the carbon whilst maintaining a high degree of breathability and comfort. The end garments will be significantly lighter. The lightweight FR fabric will offer enhanced FR and WR provided by unique and novel polymer coatings. Any enhancement would be durable and highly water repellent

Title:Efficient, Low Emission Generator
Abstract:Small diesel gensets (less than 5 kW) used by the military are often sized for maximum loads, but are run usually run at only partial load. This leads to poor fuel economy, wet- stacking, and the reliability problems associated with it. Aspen Products Group, Inc. proposes to eliminate the problem of wet-stacking by co-firing the diesel engine with a hydrogen-rich syngas to facilitate complete fuel combustion. The syngas will be generated by an onboard reformer add-on that feeds directly into the air intake of the engine.

Title:Turbocharger and Electrically Buffered Control System for Military Generators
Abstract:Diesel generators that operate at partial power can experience wet stacking, low efficiency, and poor exhaust emissions. These problems create excessive maintenance, reduced lifetime, high fuel consumption, and poor air quality. Although exhaust treatment systems can improve air quality, most technologies are impeded and/or damaged by high sulfur fuels used in some areas. The costs associated with these deficiencies are significant. As a result, we propose to develop simple, cost-effective techniques to address these shortfalls. Specifically, we plan to modify existing generator designs to include turbochargers and Electrically Buffered Control Systems (EBCSs). This work will leverage Creare’s extensive experience with turbomachines and thermodynamic systems, and their electronic controls. Our approach utilizes a large number of commercially-available components to minimize cost. We expect savings from reduced maintenance and fuel consumption to exceed the cost of implementing our technology. During Phase I, we will optimize our approach for a specific military generator, quantify its impacts, and estimate implementation costs. We will retrofit several generators with our design features during Phase II and conduct laboratory and field tests.

Title:Efficient, Low Emission Generator
Abstract:This proposed Phase I effort seeks to advance, and demonstrate feasibility of, a patent- pending technology design to address engine-related concerns in small generators as experienced by the Marine Corps and others. The Marine Corps states that small military generators frequently operate at low loads (below maximum mission profile load) and experience wet-stacking and low thermal efficiency. In addition to addressing these issues, the Marine Corps has also expressed its desire to achieve lower emissions and operational capability across a variety of fuels including diesel and JP-8. These areas can be addressed with an innovative concept to modify a 4-cycle engine into a 6-cycle continuous combustion engine. This system uses the piston/cylinder assembly and a unique valve strategy to compress air, transfer air to an insulated combustion chamber, and transfer the high pressure gases back to the piston/cylinder for power extraction. With load following controls, lower emissions, and the complete combustion of fuel inherent within this proposed engine system, Phase I will evaluate the system feasibility through comprehensive thermodynamic analysis, analysis of thermal and pressure losses associated with valve design, and determining design boundaries of the insulated combustion chamber to achieve enhanced combustion without compromising system life or thermal efficiency.

Title:MHD Earth Referenced Azimuth Detector (MERAD)
Abstract:Applied Technology Associates (ATA) proposes to develop a miniature, rapid, non- magnetic azimuth sensor by exploiting innovative magneto-hydrodynamic (MHD) inertial angular rate sensing technology. The proposed solution centers upon use of a spinning MHD sensor that outputs a modulated version of Earth rate and offers means of deriving true azimuth. Inertial rate sensing is employed to link the MHD Earth Rate Azimuth Detector’s (MERAD's) orientation accurately to the vector that defines the rotation of the Earth. This avoids the errors inherent in systems that only use magnetic field information. The MERAD technical approach draws on the high signal-to-noise feature of ATA’s MHD sensor technology. The compute intensive nature of the required mechanism control and signal processing algorithms will be implemented in a processor to ensure meeting size and power goals compatible with the need for a man-portable far-target locator capability.

Title:NOVEL COMPACT HIGH ACCURACY NON-MAGNETIC AZIMUTH SENSOR THAT IS INSENSITIVE TO LOCAL ENVIRONMENT, INTERFERENCE, AND JAMMING
Abstract:The goal of this Phase-I SBIR effort is to establish the feasibility, performance, and advantages of advanced azimuth sensors that are non-magnetic, compact, low power, light weight, rugged, insensitive to magnetic interference and electronic jamming, are not dependent on GPS signals, are readily integrated in laser rangefinders and laser designators, and are useful in Battlefield environments. The Phase-I effort includes design, modeling, and experimental demonstration of the feasibility of the novel azimuth sensor. Extensive interaction is planned with Naval and System Prime personnel to optimize characteristics of the azimuth sensor for military system applications. Finally a Phase-II demonstrator will be pre-designed in an option period allowing for transition to a Phase-II effort in which a high performance azimuth sensor system demonstrator will be built and characterized.

Title:Flexible Body Armor
Abstract:To facilitate combat operations and maintain adequate force protection, there is an immediate need for all-around body armor systems for US military forces. This need has driven advancement in developing, evaluating, modifying, and incorporating new and commercial protective materials and technologies for meeting the goal of flexible, light weight and more effective armor protection systems. Specifically, this project will focus on developing an innovative design that integrates boron carbide (B4C) nanoparticles as reinforcing or filler phases into commercial protective polymeric fabric materials such as Kevlar and ultra high molecular weight polyethylene (UHMWPE) to enhance their strength, toughness and ballistic performance. The innovative design, materials, and fabrication process proposed in this project will substantially improve the durability of soft body armor systems, while reducing the mass and bulk size, covering contoured areas of the body for US service men and women. Similar benefits are expected for law enforcement teams working to strengthen US borders and security. Based on successful demonstration of the feasibility in Phase I, the NanoMech team will optimize the process, develop quality control criteria and explore scale-up of the manufacturing process for its repeatability, reproducibility, and durability for mass production in Phase II.

Title:Wireless Battery Charging Methods for Distributed Soldier Electronic Devices
Abstract:Today’s leading technology for wireless medium power transfer (less than 1kva) from a power transmission station to a load(s) is made possible by means of a magnetically linked resonant power transmission system. This system differs from a magnetically coupled transformer system in that for the magnetically linked resonant system the power transmitter and load(s) are operating at the same center frequency, with a very narrow bandwidth. In the Phase I project, we will demonstrate the ease, reliability and effective range that Eltron’s system has. Eltron’s system design takes full advantage of system impedance matching using a custom, unidirectional power emitter and spherical receiver antenna to maintain system’s frequency and phase lock, producing a power transfer efficiency exceeding 75%. Eltron’s system can be modified to accommodate unattended, untethered automatic recharging of a single cell to multi-celled secondary battery power pack used in portable equipment. The equipment containing the secondary batteries can be placed at a varying distance within two to three meters and at any arbitrary rotation relative to the charging system’s emitter. Internal to the stated equipment will be a smart battery charger that regulates the batteries’ charge, depending on the number of batteries it contains.

Title:Wireless Battery Charging Methods for Distributed Soldier Electronic Devices
Abstract:An inductive power transfer approach is proposed, in which a backpack-deployed central power source will deliver power omni-directionally to battery-powered devices also borne by the Warfighter. Charge will be maintained in batteries without removal from the devices they are powering and without the need for cables and connectors. Phase I will address the major technical challenges, including integration of the transmitter unit into the backpack and the receiver units into the battery holders of battery-powered devices; the tradeoff between device weight and transmission efficiency; and safety and detectability. Tasks during the Phase I base program will include (1) requirements definition for battery charging for a thermal weapon sight and/or other critical items, (2) design and construction of a power transmission prototype suitable for this application, (3) test of the prototype, in order to demonstrate its capability and to identify necessary design modifications, and (4) development of plots clearly presenting the major design tradeoffs. The Phase I Option will develop and document a full-scale design for a specific battery-powered item agreed to with Marine personnel, both with engineering drawings and illustrations and with a physical mockup.

Title:Wireless Battery Charging by Adaptive Inductive Coupling
Abstract:In response to the Navy need for wireless battery charging methods for distributed electronic equipment worn or carried by the soldier, Physical Optics Corporation (POC) proposes to develop a novel wireless battery charging system using inductive coupling. Called the Battery Inductive Coupling Adaptive Recharger (BICAR) system, it incorporates such innovations as adaptive inductive coupling, a magnetomechanical-adaptive receiver module, advanced power management, algorithms, and a graphical user interface to remotely recharge batteries. The GUI profiles a given alternating power source conversion for a given battery, in terms of power and voltage, including its aging stage. The BICAR operates over wide electromagnetic frequency (60-400 Hz) and voltage ranges. It recharges typical Marine Corps devices such as the mounted thermal weapons scope. In Phase I, POC will construct a preliminary BICAR prototype and demonstrate the feasibility of the concept. By the end of Phase II, a BICAR prototype at TRL-5 will be demonstrated to the Navy.

Title:Wireless Battery Charging Methods for Distributed Soldier electronic Devices
Abstract:A problem is endangering American soldiers all over the world. Heavy individual batteries and restrictive cables are known to encumber a soldier’s mobility in combat situations. This project aims to determine the feasibility of a wireless, centralized power system that has the potential to free soldiers from wires and individual batteries, thereby improving their efficacy on the battlefield. A wireless power system designed to supply the electronics carried by a soldier, should have a range of approximately 30cm. Additionally, the system must be cost effective, efficient, lightweight, and reliable. Our company has previously created a wireless power technology that can supply energy to handheld electronics over a short distance. WiPower has spent four years researching the most efficient way to transfer power across a range of less than 1 cm. Current methodologies allow our wireless system to perform similarly to a conventional corded power supply. Our prior research indicates that our technology is a high potential candidate to meet the needs of soldiers. The research conducted during Phase I will determine the feasibility of a 30 cm range for WiPower technology. If this range is achieved, soldiers and vehicles could be equipped with wireless power in the near future.

Title:Wireless Sensor Nodes with Energy Harvesters for Joint Weapons Systems Diagnostics/Prognostics
Abstract:In this SBIR program, Agiltron proposes to develop a new class of wireless sensor nodes with integrated energy harvesters, which will be indefinitely self-powered, for use in Light Armored Vehicle (LAV) environments. The proposed effort leverages on industry- wide development in ultra-low power sensors and low-power wireless sensor network modules (IEEE 1451.5 standard), as well as Agiltron’s recently demonstrated energy harvesting technology. The proposed device and system design would enable high power harvesting efficiencies, superior reliability, a small packaged footprint, and at the same time, manufacturable at low system cost, thereby overcoming major shortcomings of existing technologies. The carefully balanced choice of commercial off-the-shelf (COTS) components and in-house development holds strong promise for near term commercialization. In the Phase I program, sensor nodes with state-of-the-art energy harvesters with ruggedized assembly and packaging that meet the current, voltage, and temperature sensing and wireless transmission requirements in LAV applications will be demonstrated. Fully functional devices will be developed in Phase II.

Title:Wireless Smart Sensor Network for Vehicle Diagnostics and Prognostics
Abstract:Maintenance activities cost DoD $81 billion a year and maintainers have only limited diagnostic capabilities for weapons systems life cycle management. Advances in sensors, embedded systems, and network information systems, make it possible to achieve unprecedented diagnostics. Luna will leverage advanced MEMS and nanotechnology to develop ultra-miniature smart sensors and network nodes for retrofit into existing weapons systems. Ultra-miniature sensing elements that detect a wide variety of parameters and network nodes will enhance diagnostic capability and coverage of vehicle systems. The wireless smart sensor network will monitor, process, and transmit health and usage information to improve accuracy, speed of diagnosis, and visibility at all organizational levels through shared data environments. During the Phase I effort, the smart sensors and network node hardware and software architecture, and communications protocols will be developed. The smart sensing system will be based on the IEEE 1451 family of standards. Luna will design an ultra-low power system with embedded power management that is compatible with a variety of energy scavenging and power storage devices. System requirements for environmental resistance and attachment to weapons systems will be established. The Phase I program will conclude with a demonstration of a breadboard prototype wireless smart sensor network system.

Title:Hollow Fiber Freeze Thaw Filter
Abstract:The Marine Corps currently uses an ultrafiltration device to provide safe drinking water in situations where outside supply is not possible and local water sources are of questionable purity. However, the current device is susceptible to freeze/thaw damage that degrades its filtration capabilities to the point where the user may no longer be protected from endemic biological threats. Under the proposed Phase I SBIR program, METSS plans to use its expertise in testing and polymer chemistry to characterize the current failure mechanism and develop improved porous fibers resistant to freeze/thaw damage while still possessing filtration capabilities that meet the Navy’s requirements. This approach will involve commercial industrial support and thus, if fully successful, have an effective plan to provide the product to the Navy.

Title:Evaluation of the freeze-thaw behavior of polysulfone hollow-fiber membranes
Abstract:The continuous delivery of drinking water to military field personnel presents a serious logistical challenge. Each soldier requires an uninterrupted supply of 1.5 to 3.0 gallons of water per day to prevent dehydration. Local water sources may be available but they may be contaminated with indigenous pathogenic organisms, chemical or biological threat agents. Presently, the military has identified an IWP filter with a low enough pressure drop to allow a soldier to drink directly through a reasonably sized filter without undue effort; however, the present filter can not maintain its initial performance after freezing and thawing cycles. Current research suggests that the mechanism of damage is not rupture due to the expansion of the water as it freezes but mechanical damage done by ice crystal growth. The objective is to evaluate the freeze behavior and confirm the failure mode of an IWP filter subjected to freezing and thawing to develop a “practical” solution. The most successful methods will increase the weight and bulk the least and not require any additional consumables. It will not make the resultant system heavy and bulky as to negate the weight and size advantage of the hollow-fiber filtration media.

Title:Live-Training Objective Performance Measures for After Action Reviews (LOPMAAR)
Abstract:Live training is the United States Marine Corps’ preferred method of training infantry operations. However, such training practices prove difficult in providing detailed assessment of the participants’ performance because of a number of factors including the number of participants and the complexity of the tasks performed. While live exercises provide maximum realism and fidelity for infantry operations, no automated assessment of performance is currently available. Efforts are underway to instrument a number of facilities to capture mission rehearsal performance. However, in order to exploit the data collected, the Navy needs to define performance measures for both teams and individuals in these live-training exercises. By automating the computation of these measures and incorporating them into an effective After Action Review process, the Navy can combine the fidelity of live-training exercises with automated measurement and enhanced feedback.

Title:Objective Live-Training Infantry Performance Metrics for Automated After Action Review
Abstract:To conduct effective after-action reviews (AARs) for United States Marine Corps (USMC) live training exercises, instructors need to automate the analysis of captured data and minimize their level of effort. In partnership with ScenPro and Cubic Defense Applications, Primordial proposes Overlord, software that automatically tags relevant events buried in mountains of raw data captured during training, allowing USMC instructors to efficiently evaluate trainees against their expert counterparts. Overlord is based on the ViSSA (Virtual Soldier Skills Assessment) software which ScenPro developed under a phase II Small Business Research and Development (SBIR) contract in 2005. ViSSA automatically detects significant events in a Distributed Interactive Simulation (DIS)/High-Level Architecture (HLA)-based virtual environment. Overlord will interface with live instrumented training ranges such as Cubic’s Advanced Systems Architecture for Urban Live Training (ASAULT). Cubic is a world leader in instrumented live training. Composed entirely of commercial off-the-shelf (COTS) hardware, ASAULT provides a state of the art position tracking system that reports trainee positions seamlessly between indoor and outdoor environments. ASAULT ranges use industry-standard data formats such as DIS, HLA, and the Test and Training Enabling Architecture (TENA). Overlord will be capable of analyzing object data captured in all of these formats.

Title:New Composite Boron Doped Diamond Coatings for Electrochemcial Oxidation
Abstract:This project will result in new, composite boron doped diamond (BDD) coatings for inexpensive metal substrates that will provide superior electrodes with improved water purification properties as well as excellent adherence and corrosion-resistance. Eltron’s composite BDD coatings contain no organic binders or materials that will be susceptible to attack by the extremely powerful reactive oxygen species (ROS) generated by a salt- free electrochemical (EC) oxidation. The coatings cure at low temperatures, eliminating the coefficient of thermal expansion (CTE) mismatch problems seen between other BDD coatings and substrates. In other applications, the coatings have shown conductivity that can be precisely tuned for specific applications. In addition, the coatings have been shown to be extremely adherent to metal, ceramic, and plastic substrates, providing good contact and a rugged electrode. The use of BDD coated electrodes will enable a salt-free EC oxidation process that reduces consumables and improves stability and ruggedness. The BDD coatings will allow sturdy electrodes and easy electrical connection to the EC system in a rugged way, suitable for military field use.

Title:Boron Doped Diamond Electrodes for an Electrochemical Oxidation Treatment to Disinfect Potable Water Sources
Abstract:Electrochemical oxidation technologies are frequently used by military forces to create disinfectant solutions for individual use water treatment. However, current technologies suffer from degradation of system components because of the added salt required for the oxidation processes. Further, over time, high overpotentials result in the slow oxidation of the DSA electrodes reducing system efficiency. Certain impurities in the feed stock salt can also complex with and degrade the DSA electrodes. To solve these issues, the Luna team proposes the use of high performance electrode (HPE) materials to create oxidizing solutions without the use of feed stock salt. The creation of ozone and hydroxyl free radicals will be facilitated by the use of boron doped diamond (BDD) electrodes. The efficiency in the reduction of harmful microbial species will be increased by exploring methods to enhance the electrode area per unit volume of solution for a given nominal surface dimension. The maximization of electrode efficiency will reduce interaction times required between source water and the electrode to achieve the specified log reduction of microbiological species and thus reduce power and size specifications for the final device. The end result will be a small, portable, and cost effective device to disinfect potable water.

Title:Novel Carbon Foam Electrodes for Electrochemical Oxidation and Capacitive Deionization
Abstract:The novel staged electrochemical oxidation/ capacitive deionization (EO/CDI) treatment system proposed here is based upon a multi-stage treatment approach using: (1) physical filtration to remove macroscopic solid particles, followed by (2) capacitive deionization (CDI) with a novel activated mesocarbon foam, (3) a unique flow-through electrochemical oxidation cell which both promotes direct oxidation at the electrode surface while producing soluble oxidizing compounds (e.g. ozone, hydroxyl radicals, hydrogen peroxide and solvated electrons) in situ, and (4) a second CDI stage to remove by products produced during oxidation and/or salts. For the current solicitation, probably the most important novel feature of the EO/CDI process is its effectiveness in simultaneously oxidizing chemical contaminants, capturing metal ions, inactivating bacteria, viruses, and other water-borne microorganisms with a low power input and a low pressure drop. The EO/CDI technology, if successful, would allow the point-of-use treatment of available water supplies. It has the capability for use in individual units while retaining the ability for scale-up to small stationary water treatment plants. The electrode materials are effective and inexpensive. EO/CDI could provide protection from inorganic and organic compounds in water while minimizing the potential for producing disinfection by-products (DBP’s), sludges, and harmful residues.

Title:Faradayic Bulk Anodizing of Aluminum Parts for Small Arms
Abstract:This SBIR program addresses the need for an innovative manufacturing process for bulk anodizing of a large number of small aluminum alloy parts, by cominbing bulk anodizing with a sophisticated electrochemical anodization technique and an innovative cell design. The anticipated results in this Phase I SBIR program include (1) development of a Faradayic anodizing process that meets the need for anodized layer thicknesses of 0.001 to 0.002 inches without deleterious surface problems, 2) process enhancement by combination with a hydrodynamic flow scheme that improves uniformity over current practices, 3) conceptual design of pilot-scale hardware that would be built in Phase II, 4) identification of a range of parts that would be investigated in Phase II, and 5) a detailed commercialization strategy for initially meeting the military need and then transitioning to a commercial need. Phase II will extend the development and validation program for both the parts of interest to the U.S. Air Force and the manufacturing process, with an extensive testing program. At the successful completion of the Phase I and II programs, our technology team will have demonstrated the novel bulk anodizing process and the associated enabling hardware at a Manufacturing Readiness Level of ~5.

Title:A Unique Process for the Bulk Anodizing of Small Aluminum Parts
Abstract:Currently, small aluminum parts are racked on aluminum prongs for anodizing which is time consuming, ineffective and costly. Bulk anodizing of small parts without the need for individual racking of parts has become a necessity for anodizing small arms parts to reduce cost, and enhance performance and reliability including uniformity of the anodized layer. Barrel type anodizing in state-of-the-art acid solutions is not effective due to the intermediate and poor anodic electrical contact. A different green manufacturing approach not involving solutions that achieves a conductive medium orders of magnitude more conductive than acid anodizing solutions permits bulk barrel type processing to achieve a uniform anodic oxide conversion coating on small aluminum parts at a foster rate. A small scale system will be fabricated without the need for individual racking of parts and bulk processing demonstrated to produce uniform oxide conversion layers/anodization on several aluminum alloys which will be characterized and compared to state-of-the-art anodizing processes. A conceptional pilot design for bulk anodizing will be prepared.

Title:Anodizing of Aluminum Parts for Small Arms
Abstract:Individual racking of parts during anodization processes is time consuming and inefficient. The objective of this proposed effort is to develop a process that can anodize large number of small parts, fabricated from aluminum alloys, using a non-racking approach while maintaining high surface quality to meet military standards. Two fixture design concepts, batch process and a non-racking fixture, are proposed. In the batch fixture design, ballasts made of porous metal foam are employed to eliminate surface defects due to contacting aluminum parts. The non-racking fixture utilizes highly porous metal foam as the electrical contact to allow maximum electrolyte diffusion, and minimize contact marks. Fixtures are attached to a vibrating axel for maximum agitation, and pulse anodizing methods are applied to achieve better surface finish quality. TRI/Austin will be teaming with two companies to assist in the development of anodizing fixtures and processes. Analytical tests will be conducted to evaluate the anodic film properties including visual appearance, film thickness, Rockwell hardness, abrasion, and corrosion resistance. The results of this research will be an efficient bulk anodizing process that is capable of high volume yield and outstanding surface finish quality.

Title:Low Bend Loss and Rugged Graded Index Multimode Fiber for Ribbon Cable Application
Abstract:Agiltron and StockerYale team proposes to develop a new class of multimode fiber that is more durable, reliable, and tight-bending to replace the current mil-spec qualified fibers used in aerospace. Our approach is a combination of a proven trench assistant design principle optimization and effective carbon coating. The new class of multimode fiber has attributes that is 100 times more bendable than standard 50/125 graded index multimode fiber, fully compatible with Gigabit Ethernet Standard, has low splice loss with conventional 50/125 multimode fiber, can withstand more fatigue with a large stress corrosion factor, and is amendable to be produced by matured optical fiber processes. In this Phase-I program, the basic concept will be modeled and the proof-of-concept fiber samples will be purchased and tested, to demonstrate the feasibility of the technology, and to finalize the fiber perform design and establish the performance characteristics of the product in Phase-II.

Title:Rugged and Durable Fiber Optic Replacement
Abstract:Hybrid Glass Technologies, Inc. (HGT) proposes to design and develop a rugged and durable drop-in fiber replacement that would provide a versatile platform for a number of photonic network-centric military avionic network applications. The key improvement over the currently used technology will be provided by the fiber coating material called hybrid glass that meets the military adverse environmental conditions. Specifically the hybrid glass coating will provide the fibers with enhanced bending strength, robustness, high temperature and environmental durability. Additional benefits include small fiber diameter, minimal bend radius, and ease of termination. The hybrid glass coating has already proven to provide the fiber with higher strength characteristics and the resistance to breaks during bending and handling therefore will require less cable protection than the current silica-based fiber optic material. The hybrid glass coating will be applied on 50 micron core graded index multimode fiber and 9 micron mode field diameter bend- insensitive single-mode fibers to provide -55 to +165 ºC operation over a 100 meter transmission distance. In addition, we propose to develop a strippable coating and to design a drop-in cable plant replacement incorporating hybrid glass coated fibers into improved cable, fiber ribbon using epoxy-free connectors.

Title:Rugged and Durable Fiber Optic Replacement
Abstract:Optical fibers are extensively used in military aircraft, both as interconnects in electronic cards and as interconnects in aircraft frames. Fiber ribbons used in computer cards suffer significant breakage failures, usually close to the connectors and at points where they have been tacked to prevent movement. Fiber cables suffer “maintenance induced breaks” when, for example, a heavy object falls on them or they are bent sharply at an anchor point. Both these situations would benefit from development of a rugged, durable optical replacement fiber. Ideally it should be a drop-in replacement for currently used fiber. Linden proposes the use of a new class of materials for use as extruded optical fiber buffer. The new materials will have high strength, low cold creep, high flexibility and kink resistant. Fibers using the new buffer can be used in both ribbon and cable constructions. The fibers will be a drop in replacement and compatible with MT and 29504 type connector.

Abstract:The Navy desires an Open Data Distribution Service (DDS) that is suitable for use in a distributed simulation laboratory environment. The implementation of a distributed simulation environment places heavy demands on technology to provide a valid and accurate simulation capability that is flexible and open. Simulation tools must be capable of supporting extremely short response times and data refresh periodicities, with timelines often measured in milliseconds. At the same time, it is important that these tools be designed with an Open Architecture approach to facilitate interoperability, extensibility, and maintainability.

Title:Rapid Tactics Development Using Existing, Low-Cost Virtual Environments
Abstract:A tremendous need exists for intelligent agents that can be created and edited without resorting to intensive knowledge engineering and programming, and which exhibit believable and variable behavior in the training contexts in which they are deployed. This proposal describes a novel method for creating and editing intelligent agents’ behavior based on using instance-based modeling and statistical learning methods that learn from the example of a person interacting in a virtual environment. These methods, which leverage structured knowledge in a hybrid symbolic-subsymbolic approach, support automatic incorporation of assessment feedback directly from the interface into an agent, allowing a domain expert to interact with an agent in a closed feedback loop through a participation in a virtual environment, instead of through lengthy reprogramming by a knowledge engineering expert.

Title:Rapid Tactics Development Using Existing, Low-Cost Virtual Environments
Abstract:It is imperative that we enable our training capabilities to evolve rapidly to support changing training needs. This, in turn, requires the capability to rapidly adjust and modify behavior models in an unprecedented manner. This capability is needed in all domains, including air, ground, surface, and subsurface, in both urban and more conventional warfare environments. The Toolkit for Rapid Behavior Modeling (TRBM) will overcome these limitations by enabling constructive behavior models to be developed rapidly and cost effectively. TRBM’s key innovation is its focus on empowering Subject Matter Experts (SMEs) and warfighters to define and modify behavior models on their own. TRBM enables them to accelerate the model development process by executing a new behavior in an existing virtual environment and capturing it for use as a starting point in development of the behavior model. TRBM also uses a simulation-independent representation for its behavior models, which eliminates the need for software engineers or a software development lifecycle in the behavior development process. This will reduce the time, effort, and cost associated with developing new behavior models.

Title:HBM DEPOT
Abstract:Current military M&S systems for training and experimentation rely on encoded human behavior models (HBMs) that must be produced and maintained by teams of subject matter experts (SMEs) and professional knowledge engineers (KEs) in an arrangement that can be time-consuming and expensive. The programming by demonstration (PBD) and machine learning paradigms offer solutions, but are not without challenges, typically producing behaviors that are too simple for operational use, require extensive supplementation by a KE and/or require large sets of examples. Soar Technology has formed a team rich in experience with Navy modeling and simulation, HBM development, artificial intelligence, and serious games for training to propose HBM DEPOT, a tool that supplements simulation-based demonstrations with a novel and intuitive guided after- action whiteboarding session based on existing research and tools. This will result in a system that captures demonstrations of Navy Aviation tactics using a low-cost Delta 3D Navy flight simulator and supplements them with an easy to use diagrammatic representation (pre-loaded with Navy Aviation general domain knowledge) and learning algorithm to generate high-quality HBMs. The HBMs will be suitable for use in any virtual environment where intelligent computer generated forces (CGFs) or non-player characters (NPCs) such as a wingman or sophisticated OPFOR are required.

Title:A Nonlinear Reduced Order Method with Overset Adaptive Cartesian/Unstructured Grid for Moving Body Simulations
Abstract:An innovative hybrid nonlinear reduced order method (ROM) for deforming unstructured mesh and overset Cartesian grid for moving body problems is proposed. Utilizing the properties of a maximum 6 degrees of freedom (DOF) of a moving body, the proposed method computes the grid deformation using nonlinear large deformation theory to preserve the original grid quality under each DOF, so that no extra computations are required during the unsteady motion, just matrix-vector multiplications. The introduction of the overset Cartesian method will provide the flexibility when dealing with extremely large deformations and deterioration of grid quality. The present method has the merits of reduced grid distortion, minimum modification to an existing code, efficient moving grid methodology with simple matrix multiplication, and minimized needs of hole-cutting and donor cell searching of overset grid. The Phase I effort is on the testing of each individual components of the method, including nonlinear ROM for unstructured deformation; overset Cartesian grid for coupling with an unstructured grid; a controlling strategy and criteria to switch between the two methods; and the successful demonstration. In Phase II, an API will be developed so that the proposed methodology is generic enough to be utilized by a variety of solvers and flow functions. The technology will be demonstrated on USM3D solver.

Title:An Efficient CFD Algorithm for Store Separation Prediction
Abstract:This SBIR Phase I project proposes to develop an efficient Computational Fluid Dynamics algorithm for store separation prediction. Compared with overset grid approach, the proposed approach avoids the tedious process for fixing the so-called “orphan points”, the failed interpolation grid points. Compared with dynamic unstructured grid approach which requires updating the CFD volume grid at each time step, the proposed approach only needs to update the so-called gridless shape functions according to the instantaneous CFD surface grid and therefore is more efficient and robust. While our ultimate goal for this SBIR effort is to develop an efficient viscous CFD algorithm for store separation prediction, due to the time limitation, our technical objective for Phase I work is to develop an efficient Euler solver for store separation prediction. As a feasibility study, the Phase I outcome will ensure the validity of the proposed approach for fast carriage load prediction. Therefore, it is meaningful to further extend the approach to viscous flow simulation in Phase II.

Title:Development of Methodology for Moving Body Simulation Based on Computational Fluid Dynamics
Abstract:For moving body problems with complex geometries, a robust and reliable approach to constructing computational domains is needed. Based upon our extensive engineering experience with overset grid methods, Digital Fusion Solutions, Inc. (DFSI) proposes to implement new and transfer existing technologies to alleviate the challenges facing unstructured overset grids. The techniques to be implemented are: 1) an innovative hole- cutting technique based on the solution of Green’s Function, 2) a general finite-volume flux reconstruction approach for boundary cells, and 3) an optimized, or minimum, overlap algorithm to ensure that the global solution is computed on only the best cells. Unstructured overset methods show great potential for moving body problems particularly in automated grid generation. The current trend is to apply structured overset grid techniques to unstructured grids, where long standing issues related to orphan points, interpolation inaccuracies, and searching inefficiencies are still not adequately addressed. For moving body problems, a generalized overset capability is highly desirable, to avoid methods that require grid stretching, regridding, and interpolation. Under this SBIR we will implement these new techniques for two-dimensional problems using an open-source flow solver. Phase II will extend the methods to three-dimensions, and transfer the technology to the engineering analysis environment.

Title:Innovative Concepts for Ultra-light and Reliable Hydraulic Actuators
Abstract:It is proposed to initiate a research program to design and manufacture a composite housing gear system for the next generation of NAVY F/A-18 and F-35 aircrafts. The present systems use steel housing which lack the low weight requirements for the design of the Wing Fold Transmission systems. The proposed effort relies on replacing the current steel made Ring Gear Housing System with the Carbon Reinforced Composite Materials. The application of composite materials in aerospace and automobile as structural materials is expanding primarily because its properties match high strength steel alloys with large savings in weight. Although there are many advantages in the use of these composites, there are many issues in the fatigue life, corrosion and other mechanical properties that need to be considered in the use of these composites in corrosive environments. One solution to address the corrosion and environmental issues is the use of proper coating systems for the final composite product. We propose to develop the composite and coating system and test them for their life, corrosion and other mechanical properties. The result of this work would provide a complete system that can meet all the design requirements by the NAVY.

Abstract:Integran Technologies USA Inc. (Pittsburgh, PA) is pleased to provide this proposal in response to the Navy Small Business Innovation Research (SBIR) Request for Proposal (RFP) “NAVY 08-119: Innovative Concepts for Ultra-light and Reliable Hydraulic Actuators”, to investigate the use of a novel high strength nanostructured metal (Nanovate™) as a thin structural reinforcing shell on ultra-lightweight carbon fiber reinforced plastic (CFRP) actuator rods and cylinders. In the proposed project, Integran seeks to address the intrinsic deficiencies of CFRP by applying nanometal to the working surface of the CFRP actuator rods and cylinders to provide increased surface durability, wear resistance and specific strength/stiffness of the CFRP substructure at ambient and elevated temperatures, thereby enabling the use of CFRP for ultra-lightweight actuators. The high strength of the nanostructured material will allow a thin structural reinforcing coating, thus maintaining the overall lightweight nature of the component. The successful execution of this project will provide a proof-of-concept demonstration as well as baseline mechanical property data for nanometal/composite hybrid structures at a range of temperatures, thereby allowing engineering designers to incorporate the use of these structures into advanced engineering components, including lightweight actuators.

Title:Smart Gasket for Catapult Low Loss Launch Valve (LLLV)
Abstract:Availability and operation of all four steam catapults is vital to carrier flight operations. The valve directing steam to the catapult cylinders employs gaskets that fail unexpectedly due to degradation of filler preload. The gasket condition affects launch valve performance and eventually necessitates replacement of the launch valve assembly to restore performance. The gasket failure and lengthy valve repair process are detrimental to carrier readiness and increase maintenance costs. Currently, maintainers are unable to monitor gasket condition or predict gasket remaining useful life. To address this critical need, Luna Innovations will leverage its non-destructive evaluation and health monitoring expertise to develop a retrofit system for detecting gasket integrity using ultrasonic transducers mounted to the valve exterior. Key advantages of this approach are: 1) no valve design changes, 2) no gasket modifications, and 3) the external monitoring system can be directly wired to catapult systems. This approach supports rapid integration and is a more reliable alternative to wireless/energy scavenging approaches. The Phase I effort focuses on demonstrating ultrasonic measurement sensitivity to gasket load and damage state using representative housing and gasket geometries and materials. The hardware and software to support a gasket diagnostic and prognostic health monitoring system will be established.

Title:Weapon System Performance in Complex Radio Frequency (RF) Environments
Abstract:Many highly accurate electromagnetic solvers have been developed based on a variety of full-wave and asymptotic algorithms. The tools provide cost effective insight into electromagnetic phenomena and allow analysts to perform trade studies while reducing expensive measurements. By itself, a well-developed EM analysis tool is not sufficient to produce accurate results; accurate results require an accurate input geometry model that is designed to meet the EM solver’s requirements. The development of an accurate CAD model and associated mesh of a particular platform can be a labor intensive task. We propose to develop a graphical software tool that will greatly reduce the amount of time spent on preparing meshes and/or surface models for use with EM solvers. The tool’s inputs and outputs will include both triangular and NURBS asymptotic models as well as triangular and quadrilateral full-wave meshes. The tool will allow analysts to automatically identify problems with existing meshes based upon user specified criteria related to edge length, aspect ratio, connectivity, etc. Our approach will address the healing of existing models and meshes, the conversion between quadrilateral and triangular meshes, conversion between asymptotic and full-wave meshes, and the conversion between meshes and NURBS models.

Title:Weapon System Performance in Complex Radio Frequency (RF) Environments
Abstract:In this proposed effort we seek to develop mesh repair algorithms that optimize preexisting meshes for CEM full wave solvers. We will investigate automated methods for converting asymptotic meshes to full wave CEM solver meshes. Mesh repair modules will implemented and accessed from a stand-alone tool with 3-D visualization capabilities or via C++ libraries that may be added to existing codes. The modules will include mesh resolution and quality repair capabilties using smoothing and mesh regeneration techniques. Mesh connectivity repair will be provided by a method that performs automatic restitching of the mesh across unconnected mesh boundaries. Procedures for converting asymptotic meshes to four sided surfaces, such that new fully connected mesh may be generated, will be implemented and tested. HyPerComp's many years of experience with grid generation technologies makes it well positioned to successfully implement the proposed techologies and provide greater usefullness for preexisting meshes, which can be very time consuming to create.

Title:Advanced Intelligent Web-Based Options to Acquire and Analyze Aircraft Health and Test Data
Abstract:Automated assessment and forecasting of aircraft health status has become a prime requirement for safety, reliability, and cost streamlining for 21st century’s aviation sector. Presently, a variety of flight data, functionality, performance, and maintenance information are being collected and some are stored in databases, but an integrated health management (HM) system that utilizes all these information is virtually nonexistent. Qualtech Systems, Inc. in collaboration with Aptima, Inc. proposes developing an integrated multi-source data acquisition and analytic solution for facilitating diagnostics and prognostics, and providing decision support for operations, maintenance, logistics, supply chain, and military flight quality assurance related processes. Intelligent agent- based techniques will be used for gathering data from heterogeneous sources. Multi- disciplinary analytic techniques including signal processing, time-series-analysis, multivariate statistics, and probabilistic decision fusion, coupled with dependency model- based techniques are envisaged for the HM solution. An optimal decision-oriented user interface will satisfy information dissemination and visualization requirements. Preliminary theoretical development will involve a limited number of simulated data sources from a target naval aircraft. Software implementation and deployment of the solution on the target platform will be performed in subsequent phases of the work. The resultant integrated and flexible HM solution will have applicability across various military and commercial platforms.

Title:Advanced Intelligent Web-Based Options to Acquire and Analyze Aircraft Health and Test Data
Abstract:Topic Synopsis: Current aircraft disposition tools are not designed to take advantage of predictive prognostic information that will be available on new systems such as the F-35 PHM system or the proposed Maintenance and Monitoring system for the E-2D Hawkeye. The central challenges in this topic are to (1) develop automated reasoner technologies to distill large volumes of PHM data into actionable information, and (2) allow secure web- based access by commanders and maintainers so that multiple users can take advantage of the new knowledge provided by PHM to more efficiently disposition their aircraft regardless of their location. Proposal Prognostic health management (PHM) systems generate volumes of data on component health. Web-based tools are needed to automatically assimilate and analyze this data, and present findings and recommended actions to the user, regardless of the user’s location. Automated reasoner tools are necessary to ensure that PHM data is utilized for maximum benefit, allowing maintainers to focus on maintenance rather than data interpretation, and to present capability and readiness information to commanders and decision makers. Sentient Corporation will leverage its prototype AutoReasoner, including its defined automated reasoner algorithms and software tools for fusing PHM data into current and predicted capability information, to create a web-based interface for accessing and analyzing PHM data. Phase I activities will include research on migration of the existing demonstrated prototype to a web-based format and a demonstration of Sentient’s novel model-based prognostic data fusion technique, a fuzzy expert system for interpretation, via a web-based user interface. Phase I will utilize Sentient’s extensive data drawn from the CH-53 E HUMS database and will include multiple realistic maintenance scenarios. Phase II will include further development and web-based access. NOTE: We would be happy to provide additional detail on our approach if desired. Partnering: If awarded this project, Sentient Corporation would like to partner with one or more E-2D OEMs to gather information on available PHM data, learn about potential ground station software tools, and discuss database interfacing standards. Sentient has successfully partnered with multiple OEMs in the past. Sentient will leverage its access to the Goodrich HUMS and MDAT systems for this project. We would also like the OEM to critique our ideas for the reasoner system and data presentation. It is likely that a meeting at the OEM’s facility could be arranged during Phase I. We are open to a subcontracting arrangement to help the OEM cover the cost of their time. Sentient Corporation has an outstanding record of winning SBIRs in the PHM area. We are the largest SBIR contractor in Idaho even though we focus exclusively on PHM. Sentient has a reputation for doing excellent work and has been awarded over 8 Phase II contracts to date. In addition, Sentient actively works to transition successful projects to the field. For example, our bearing prognostic modeling software that was developed for the DARPA Prognosis Program has already been licensed to an engine OEM.

Title:Advanced Intelligent Web-Based Options to Acquire and Analyze Aircraft Health and Test Data
Abstract:This proposal focuses on the development of an innovative, web-based application to help solve one of the fundamental problems facing aircraft management today: data management. This problem is outlined as follows. Aircraft health management is data- driven. A broad range of disparate data sources exist, many of which are essential for accurate, near real-time aircraft health monitoring and maintenance. These data sources are often incompatible with each other, in terms of source (measured aircraft response, maintenance data, analytical models, etc.), storage (different computer systems), format (paper, electronic: ASCII, binary, spreadsheet, warehoused in relational database), architecture (procedural, object-relational, object-oriented), and design (open source, proprietary or unique design). A solution must address the following five (5) key issues: 1. Acquisition – pulling data from all required sources, 2. Integration – tying all meaningful information together into one aircraft “entity”, 3. Analysis – turning data into decision, 4. Exchange – sharing within the larger community and promoting collaboration, and 5. Data advancement – pushing data downstream for further use and innovation.

Title:Automated Characterization of Communications, Electronic Attack, Radar, and Navigation Systems
Abstract:One of the most important problems encountered in an electromagnetic environment is that of providing compatibility between radiating and receiving RF equipment within the environment. This problem is a type of electromagnetic interference and the goal of RF system designers and analysts is to achieve electromagnetic compatibility where no interference problems exist between the various RF systems. As an increasing number of RF systems are installed on Navy aircraft, the cosite interference problem becomes more and more challenging. To further complicate matters, modern RF systems are often capable of operating over many channels and thus the operating frequency range of a single system can be very large. Also, a modern RF system may be capable of supporting multiple modulation schemes and modalities. These factors represent a major challenge to analysts who wish to simulate cosite interference problems since RF system models are not readily available. Our team proposes to develop an automated measurement system (AMS) that will aid in the development of both low fidelity (spectrum) and high fidelity (behavioral) models for use with cosite analysis software. The AMS will automatically and non-invasively extract performance parameters and characterize subsystem components of transmitters and receivers while minimizing human interaction.

Title:Antenna Array and Beamformers to Support Ka-Band Brownout Radar Systems
Abstract:BCO’s Phase I goal is to design an Antenna Array and Beamformer for rotorcraft to adapt to a rugged COTS radar module that is in production in lots of 10,000 for use on automobiles. This automotive radar is a K-Band unit with a phased-array antenna that can be stepped through 140 degrees in azimuth and which provides 20-inch range resolution. A chain of nine of the radar modules is capable of providing the hemispheric coverage sought for the Beamformer. The projected selling price for BCO’s design is well within the $10,000 target. There is a tradeoff between range and update rate. When scanning out to 80 feet the hemisphere can be scanned at up to 125 times per second. With update rates of up to 3 times per second scanning out to 490 feet is achievable. Within our design we will develop a sidelobe blanking algorithm to reduce clutter, and extend range and coverage of beam thru broad/fan beam lens designs. Our effort will include aperture placement analysis and simulation as well as polarimetric tradeoff analysis. The success of the program will be enhanced with machine prototyping of lenses and lab testing in Phase I.

Title:Brownout Radar Beamforming Using Electronically Reconfigurable Apertures
Abstract:In a number of arid regions of the world, recirculation of dust by the rotorwash of helicopters results in the loss of visual cues during helicopter approach and landing. This condition is typically referred to as brownout. This is a serious problem for all services and leads to numerous aircraft and personnel losses in Afghanistan and Iraq. The effectiveness of the conventional approach of using spotters positioned in aircraft doorways to call out and maintain clearance from obstacles has obvious limitations, especially in the most degraded visual environments. An “Electronic Bumper” system would detect and track major obstacles including other aircraft in flight during brownout and virtually all low/no visibility approach and landing. An active RF system is preferred, one operating at high-enough frequency and bandwidth to provide the needed system resolution. SNC’s electronically reconfigurable aperture (ERA) technology is ideally suited to this task. ERA is a patented electronically steerable array technology that has been demonstrated at across the range of frequencies of interest. This proposal describes the development of an antenna and beamformer architecture that provides functionality required for use in brownout radar systems.

Title:Automated Maximum Density Analysis Tool for Spot Factor Generation
Abstract:The development and introduction of new aircraft for the Fleet, or the deployment of existing aircraft on a new carrier, requires knowledge of the deck area, or “spot factor,” that characterizes the particular aircraft type. Currently, aircraft spot factors are obtained by iterative, manual methods that are very time consuming. NAVAIR is seeking the creation of a software tool to automatically perform these calculations and free manpower for other duties. The problem of maximum density packing of airplanes in available deck space is largely equivalent to that of reducing material wastage in stamping and cutting operations in the metal-fabricating, textile, and leather industries, where it is called nesting. Optimation is a leading U.S. provider of nesting software to the metal- forming and textile industries, with more than 500 customers worldwide. To meet NAVAIR’s needs for an automatic spot factor tool, Optimation proposes to expand and customize its AxiomVE nesting software and its accompanying user interface (UI). Man- decades have gone into the development and testing of AxiomVE to make it versatile and robust. The Navy will receive the benefit of this previous development effort, and it will be leveraged by Optimation to develop the high-capability software that meets NAVAIR’s spot-factor-calculation needs.

Title:Automated Maximum Density Analysis Tool for Spot Factor Generation
Abstract:Setting and evaluating spot factor requirements are key steps in the delivery of ship- compatible aircraft to the Navy. However, the current process of generating spot factor results is labor intensive. Templeman Automation LLC (TALLC), in cooperation with Magestic Systems Incorporated (MSI), proposes an automated solution to spot factor and maximum density calculations optimizing the effectiveness of the algorithms employed to identify globally optimum packing solutions and the responsiveness of the system to imposed geometry constraints. MSI’s has over 30 years of experience developing packing and nesting software, with products and services that are used in the United States and throughout the world. TALLC’s staff brings over a decade of experience in Navy system design, shipboard graphical interfaces, Mil-Spec manual development, and Navy computer-based training materials. With the proposed software tool, “TruPlanePack”, nesting can be done both dynamically and in batch mode. All software capabilities will be accessed and controlled using an intuitive Windows GUI for maximum efficiency and usability. Input and output of aircraft packing data will be made available in numerous formats including AutoCad 2006, as well as TALLC’s 3-D flightdeck visualization and simulation environment for realistic imaging of the resultant aircraft spotting.

Title:Sensor Fusion and Display for Degraded Visual Environment (DVE)
Abstract:Brownout is the number one operational problem facing military rotorcraft today. Visual obscuration, combined with nose-up attitude during landing, make identification of landing area hazards difficult or impossible. To address this problem, CG2 is proposing a system that combines data from a LIDAR sensor and CCD or IR cameras mounted on the rotorcraft with telemetry to produce a synthetic vision display that allows the helicopter to land safely. The system will generate a virtual scene using geometry extracted from the LIDAR data combined with correlated camera imagery so that objects may be identified more easily. The rotorcraft telemetry will be used to render a real-time scene that accurately depicts the position and orientation of theship relative to the terrain, with a choice of viewpoints. The solution will be validated in a simulation environment as well as with real sensors, and be capable of running on ruggedized, embedded hardware.

Title:Sensor Fusion and Display for Degraded Visual Environment (DVE)
Abstract:A joint venture team consisting of three small businesses, Monterey Technologies, Inc. (MTI), xVS and Aireyes will perform this work. The ultimate goal of the team is to produce a functional, Fused Sensor Image Display System (FSIDS) that merges information from multiple sensors such as radar, LADAR, IR, and other sensors with a terrain data base to produce a synthetic image of a helicopter landing area on a panel-mounted display. The inclusion of multiple sensor information in the FSIDS display compensates for the inability of a Synthetic Vision Systems (SVS) to display detailed, current obstacle information relevant to Navy helicopter approach and landing maneuvers, e.g., trees, brush, boulders, ditches and debris. The team has already developed an Integrated Multisensor Imaging System (IMSIS) for the Army the provides a fused image of multiple sensors and an SVS for flight and navigation. Using IMSIS as a starting point, this work will concentrate on the sensor requirements and software for creating a detailed, synthetic rendering of a limited landing area, and the addition of appropriate display symbology. The Phase I work will produce one or more animated displays illustrating the FSIDS design to demonstrate the capability to present, and the effectiveness of, imagery for approach and landing. The design goal is a rotorcraft display to allow the pilot to easily interpret landing area terrain and avoid obstacles and hazards in zero visibility conditions.

Title:Sensor-Fusion Landing Augmentation Three-Dimensional Display System
Abstract:In response to Navy needs for a real-time rotorcraft display that depicts a landing site area using fused sensor data while an aircraft approaches and descends into a landing zone, and helps helicopter pilots to land in degraded visual environments, POC proposes to develop a new real time Sensor-fusion Landing Augmentation Three-Dimensional (SLATD) display system based on augmented fusion display of 3D information acquired from the multiple imaging sensors in real time. The SLATD system can present real-time landing zone imagery based on the fusing of sensor data, thus enabling rotorcraft pilots to see nearby objects/obstacles for the control and safe descending of the aircraft in brownout conditions. In Phase I, POC will prove the feasibility of the proposed approach by presenting an analysis along with a hardware demonstration prototype of display technologies that can be used or enhanced for the depiction of a landing site area. In Phase II, POC will finalize a design, build one or more prototype devices to ascertain the automation of the fusing of sensor data, and display in real time a depiction of the landing area and rotorcraft dynamic flight situation during approach and landing.

Title:Non-Contact Cure State Measurement
Abstract:Manufacturing processes are typically delayed from several minutes to several hours while coatings, sealants, and adhesives sufficiently cure to allow subsequent operations. Local environmental conditions can accelerate or decelerate cure depending on the chemistry of the materials, which makes degree of cure a variable over time and ultimately results in built-in down-time to assure sufficient cure is achieved. A technology for determining the relative state of cure for a variety of known coatings, sealants, and adhesives, without compromising the integrity of the applied material, would be a manufacturing enhancement and production time reduction factor. The technology must ultimately be able to accommodate slight variations of chemistry within the chemical classes such as exist among different vendors or due to effects of various fillers and must be measured on substrates consistent with aircraft manufacture. In this SBIR we will develop a design concept for a non-contact cure state measurement instrument that is based on Laser-Induced Fluorescence (LIF) Spectroscopy. Develop a protocol for defining the state of cure for each application category (coating, sealant, adhesive). Demonstrate the proposed approach on the coating (epoxy or urethane), sealant (polythioether or polysulfide), or adhesive (epoxy, acrylic, urethane).

Title:Air Coupled Ultrasonic Guided Waves for Non-Contact Cure Monitoring
Abstract:A diagnostic tool for evaluating relative cure state in adhesives, coatings, and sealant systems would help increase production efficiency by avoiding unnecessary delays between applications while ensuring proper performance based on complete cure of the material system. Luna’s approach leverages ongoing developments of air-coupled ultrasonics and nonlinear acoustics to provide a solution with the potential for low-cost, high inspection efficiency, and ease of operation. The approach is based on monitoring guided wave velocity and attenuation whose equilibrium indicates complete cure. Luna’s line-based measurement approach provides greater flexibility based on inspection time and necessary spatial resolution compared with more common point-based measurements. The anticipated results of the Phase I effort include the development of a numerical model for optimizing sensitivity, proof-of-concept measurements on pertinent material systems deposited on Al 2024-T3 substrates in the based period and extended to composite substrates in the option. The transition to Phase II will include initial electronic design of a prototype device.

Abstract:Physical Sciences Inc. (PSI) proposes to develop and demonstrate a sensor non-contact measurement of the degree of cure of recently applied coatings. The sensor will use recent advances in ultrashort pulsed laser technology to provide an effective and accurate standoff thickness measurement. It will operate at Far-IR wavelengths (THz frequencies) where transmission through commonly used coating materials and adhesives is anticipated. This sensor will have two modes of operation. For materials greater than a few mils thick, time-domain ranging methodology will be combined with the measured Far-IR optical properties of these coatings to determine the overall state of cure of the bulk material. For thinner coatings, the Far-IR optical properties of the surface will be monitored. The Phase I program will demonstrate the feasibility of the approach using an existing laboratory apparatus with some application specific modifications. The Phase II program will develop and demonstrate a prototype sensor.

Title:Aqua-Ionic Detector
Abstract:The U.S. Navy is seeking a compact MEMS-based sensor system to detect and classify surface or subsurface bodies in coastal shallow waters, bays, port areas, and waterways, on the basis of weak electromagnetic (EM) signals or EM field deviations. Available technology is limited to acoustic detectors and magnetometers. To address the Navy need for an underwater EM field detector, Physical Optics Corporation (POC) proposes to develop a new Aqua-Ionic Detector (AID) based on the nonlinear conductivity of solid electrolytes. In contrast to its bio-prototype, the shark, the proposed detector will detect the gradient of an ionic charge even in a static position. The AID will be a low- observable underwater sensor, sensitive to low-frequency distortions of EM fields, meeting the Navy need to detect small and slow moving objects in the cluttered environment of littoral waters. It will include an on-chip array of microfluidic sensor cells, electronics, battery pack, and transceiver for networking the sensor grid nodes. In Phase I, POC will demonstrate the feasibility of the AID approach by fabricating and testing a conceptual prototype. In Phase II, POC plans to develop a series of device prototypes to iteratively improve performance and demonstrate the technology in a realistic tactical environment.

Title:Pulse Power Electrical Energy Storage Device
Abstract:Navy aircraft programs and upgrades will require advanced electrical energy storage devices that provide extraordinary power, for example one that can deliver 1500 W average power for 5 seconds at 1.5 V, be recharged at several hundred amps, then discharged and recharged repeatedly up to 10,000 times. The weight of this storage device should be less than one-half pound. State of the art commercial energy storage devices will not meet theses requirements. We propose to define, design, and construct an advanced electrical energy storage device that will reliably meet there requirements. Our approach is an asymmetric electrochemical capacitor having a lead oxide positive electrode, sulfuric acid electrolyte, and an activated carbon negative electrode. Although optimized for this Navy application, anticipated advances in electrical energy storage technology should assist a broad range of energy harvesting applications including hybrid and electric vehicles, and be suitable for internal combustion engine cranking particularly at low temperatures. Furthermore, the proposed approach should offer substantial cost savings over similar commercial products.

Title:QynCap Energy Storage Device for Airborne Directed Energy Weapons
Abstract:Qynergy proposes to design/build an innovative asymmetric ultracapacitor (QynCap) to provide energy storage for Navy aircraft pulse power applications. These devices will improve the Warfighting ability of fighter aircraft by enabling the use of laser-based weapon systems. The QynCap will contain a nickel oxy-hydroxide cathode and a high surface area carbon anode immersed in an aqueous electrolyte. The use of a battery electrode (nickel oxy-hydroxide) allows for a higher capacitance per weight and volume than traditional ultracapacitors. Ultracapacitors in general and QynCaps specifically are known for their high power density, high cycle life (ability to charge and discharge many times) and fast recharge time. For this application, the QynCap is superior to lithium-ion batteries for a variety of reasons. The QynCap operates well over a wide temperature range (-40°C to +71°C), utilizes environmentally friendly substances (i.e. nickel, carbon, KOH) versus dangerous Li+ ion compounds, is not subject to thermal runaway if overcharged and does not require thermal management. Because the QynCap is an ultracapacitor, it can be charged and discharged over 100,000 times and be properly sized to provide the power required.

Title:Innovative Approaches for the Flaw-Tolerant Design and Certification of Airframe Components
Abstract:Fatigue life of airframe components is greatly influenced by many intrinsic and extrinsic factors. The nature of wide scattering in fatigue life makes it very difficult to design a component against fatigue failure. The huge consequences of life and property loss associated with premature fatigue failure therefore push airframe design toward over conservativeness. It is very desirable for airframe industry to have access to an analysis methodology that accurately and reliably treat material variability in the fatigue crack initiation and growth responses of aerospace structural alloys. The goal of the present SBIR project is to fulfill these critical needs by developing a physics-based computational methodology capable of predicting the stochastic nature of fatigue life in airframe components.

Title:Innovative Approaches for the Flaw-Tolerant Design and Certification of Airframe Components
Abstract:The principal objective of the proposed Phase I SBIR project is the development of a reliable predictive capability for the evaluation of flaw tolerance in metallic and composite airframe components, given part specifications, material properties, initial flaws, such as voids, inclusions, heterogeneous grain structure and design load spectra. The proposed concept is based on the idea that the safe life methodology and the flaw tolerance approaches fit within the same paradigm if we associate failure initiation and crack propagation events with deformation states of representative volume elements. The paradigm applies to metals and composites. The critical values of the deformation states depend on the material systems under consideration. The methodology of verification and validation will be applied, utilizing existing experimental data and the concept of hierarchic multi-scale models already supported by ESRD’s proprietary software StressCheck. Because statistical variations in the manufacture and therefore the mechanical response of structural components are unavoidable, prediction of structural and strength responses must be understood in a statistical sense.

Title:Improved Analysis Techniques for Prediction of Avionics Electromagnetic Interference and Vulnerability - IntegratedEMPro System
Abstract:For modern, complex aircraft systems and avionics subsystems, coupling full-wave solutions to the electronic circuitry models is critical in order to accurately predict RF (radio frequency) system-level performance in the presence of electromagnetic signals originating from other avionics on the aircraft, high-power transmitters on other aircraft or ships, or even from microwave weapons. However, the unavailability of the circuitry models at the full vehicle level makes a comprehensive analysis very challenging. Most of the aircraft components such as Line Replaceable Modules (LRMs) are not always available with their full circuit models. However, many LRMs undergo MIL-STD-461 and MIL-STD-464 compliance testing, which provides radiated emissions/susceptibility and conducted emissions/susceptibility data. Therefore, it is important to integrate these data sets and models into a multi-physics based analysis tool to carry out practical system- level EMI analysis of electronic systems inside an aircraft. This proposed effort is to make significant innovative improvements to physics-based electromagnetic interference/vulnerability (EMI/V) tools by incorporating system performance parameters and characterizations of subsystem components within aircraft transmitters and receivers. A detailed description of the information requirements is developed for field- circuit interaction computational engines and multi-physics simulators. A scattering matrix approach is used for combining time and frequency domain analyses of circuits and LRMs, including their physical model library with aircraft radiating components to achieve a seamless integrated-level solution. Consideration is also given to how the overall prediction accuracy degrades as a function of the level of detail associated with the model library. Proof-of-concept validations will to be performed on a variety of canonical problems and limited number of real-world problems.

Title:Improved Analysis Techniques for Prediction of Avionics Electromagnetic Interference and Vulnerability
Abstract:Physics-based modeling and simulation tools for predicting electromagnetic interference (EMI) and vulnerability (EMV) between RF systems are playing an increasingly important role in system level performance predictions. In order to accurately capture all of the complexity associated with RF systems on a modern military platform, very sophisticated multi-physics simulators using models of multiple levels of fidelity are required. In order to instill a high level of confidence in the tool’s predictive capability, analysis improvements based on lessons learned in a complete and careful measurement-based validation on real-world systems is a must. Under the proposed project Delcross Technologies and its team will undertake a comprehensive measurement-based validation of its Electromagnetic Interference Toolkit (EMIT) based at first on a canonical test system and then on a complete modern airborne system involving multiple RF systems. Based on the benchmarking against these systems, enhancements to EMIT’s multi-physics analysis engines and field-circuit interaction module will be identified and implemented. The methodologies used for creating models of RF components to be used by the simulator will also be refined based on the measurements. The ultimate outcome of this project will be an improved and fully-validated multi-fidelity/multi-physics simulation tool for the analysis of cosite and intersystem EMI.

Title:Synergistic Composite Design Data Approaches to Support both Propulsion and Airframe Applications (MSC P8030)
Abstract:Development and use of new (composite) materials is imperative for continued advancement of airframe and engine systems. It is expected that this accelerated insertion of materials can be facilitated through development and validation of analytical models that guide and supplement experimental characterization of new materials to reduce the number of physical tests to the minimum number needed to insure that reliable data exist to support both airframe and engine designer needs. In this proposal, Materials Sciences Corporation outlines a work plan for meeting this objective by assembling and linking multi-scale (i.e., micro and macro) material models, demonstrating techniques for including statistically based properties and automatically providing written and graphical output of data. Initial validation of the analysis toolset will be conducted using polyimide resin carbon fiber prepreg design data provided by Renegade Materials Corporation.

Title:Synergistic Composite Design Data Approaches to Support both Propulsion and Airframe Applications
Abstract:Polymeric composite structures offer the potential for significant weight savings over metallic parts in aerospace applications due to their high strength to weight ratio. In order to design aircraft and engine composite structures, an extensive design database package is required. The generation of this composite database is a time consuming process that can cost up to several million dollars for just one material. In addition, a single design database that can be used for both propulsion systems and airframe structures has never been achieved in the composite industry. The purpose of this Navy Phase I SBIR is to develop innovative methods and analysis techniques that can support both the propulsion and airframe design community to insert high-temperature organic matrix composites into military and commercial platforms. A parallel path approach will be used to experimentally and analytically derive solutions in order to create a single designer database that can be used for allowables. This will provide the existing programs such as JSF as well as future weapon systems with validation and quality assurance of high-temperature composites applied through a database that is common to multiple users, has statistical continuity, and shows reduced testing via use of analytical predictive tools.

Title:Edge Bonding of Infrared Windows
Abstract:Onyx Optics, Inc. proposes to apply its patented AFB® (Adhesive-Free Bond) composites process that has been developed for solid state laser components to the edge bonding fabrication of IR windows. The key process step is to obtain optical contact between the components to be bonded, followed by heat treatment. There are a number of techniques of establishing this optical contact but they all result in an interface that is bonded mainly through Van der Waals forces after at least moderate heat treatment and out-diffusion of volatile species. Van der Waals forces consist of three types: fixed dipole/fixed dipole interactions, fixed dipole/induced dipole interaction, and induced dipole/ induced dipole interactions, respectively. They become prominent when the separation distance between two adjacent solid bodies becomes much smaller than any wavelength of the random dipole field. Lifshitz quantum field theory will be applied to the specific case of composite infrared windows and linked to experimental results. AFB® composites will be characterized and compared with non-composite controls in terms of: Mechanical properties: tensile fracture strength, fracture toughness, elastic modulus, stress birefringence. Optical properties: Transmitted wavefront as function of angle of incidence, refractive index, transmission between visible to far IR.

Title:Innovative Low-cost, In-situ Consolidation Head for Complex Geometry Thermoplastic Fiber Placement
Abstract:Accudyne proposes a SBIR program, endorsed by Sikorsky, Cytec Engineered Materials, and NASA-LaRC, to develop a cost-effective thermoplastic automated tow placement (ATP) process and demonstrate it by fabricating and testing a complex contoured skin (Phase 1) and a CH-53K rotorcraft lower cabin or ramp skin (Phase 2). The process employs in situ consolidation, avoiding the autoclave. The targeted part properties are those measured from autoclave-consolidated laminates. The selected Cytec APC-2 material system features inherent toughness, matching rotorcraft application requirements. For Phase 1, Accudyne will employ their already operating thermoplastic heated head that features full conformable compactors, individual tow-cut-and-add, and creates excellent microstructure. This plan will allow the rapid identification of the challenges to fabricating the complex contoured parts. Following Phase 2, Accudyne will offer an automated fiber placement machine and heated head for sale to the industry that is capable of fabricating the desired parts without using the autoclave.

Title:Innovative Low-cost, In-situ Consolidation Head for Complex Geometry Thermoplastic Fiber Placement
Abstract:xxxIn-situ fiber placement is able to offer a wide and robust processing approach that is well suited for many aerospace structures. Flat, single curvature and large radius complex curvature parts can be effectively handled with the current in-situ techniques. However, there are limitations associated with this process. The use of a rigid metallic consolidation applicator is routinely used in the in-situ process for a few different reasons such as extremely high processing temperatures and the need to evenly distribute the consolidation force across the width of the material. Depending upon material width, thickness, resin system and part curvature the use of a rigid roller to apply effective consolidation force is restricted. Additionally, with some in-situ processing approaches the ability to apply individual tows of material with a single processing head is problematic. Finding a modified or alternative approach to apply a consolidation force that is more conformable and demonstrate individual tow control is a way to make the in-situ process more valuable. Our objective in this Phase 1 SBIR will be to determine the feasibility of a conformable consolidation head, determine suitable evaluation criteria for structures made with a conformable head and design conceptual solutions for the issues at hand

Title:Fail Safe Composite Aircraft Arrestment
Abstract:Navy pilots have landed for years by capturing a heavy steel cable designed to stop them safely on carrier decks. Multiple cable sets strung across the flight deck are responsible for transferring enormous aircraft deceleration loads to below-deck hydraulic arresting engines. Current steel cables are very heavy, and must be changed after a relatively low number of landings. As the highly lubricated cables are continuously tested with 100,000 pounds tensile loading, outer steel wires fail visually, indicating need for replacing the entire cable. Realizing the simplicity and ease of this readily observable failure, KaZaK will develop a new composite/metal hybrid that features both the current visual damage indication and a failsafe construction. This new KaZaKable will have half the weight of the present design, with many times greater operational lifespan. KaZaK proposes to develop and demonstrate an automated pultrusion/braiding technology to manufacture the new cables at very low cost. Scale model cables will be built and tested in Phase I. The fail safe cable system development will be completed in Phase II with a variation of a current KaZaK cable fitting design. Extensive commercialization experience will catalyze KaZaK’s success for the next generation cable insertion into the fleet.

Title:Cure System Equipment Optimization for Rapid Cure Epoxy Coated Fiberglass
Abstract:Based on Agiltron’s extensive experience of design and fabrication of UV LED cure systems that are currently employed in the fiber optics field, we propose to construct a new cost-effective UV LED-based cure system and epoxy resin for the rapid cure epoxy impregnated fiberglass for galvanic barrier ply applications. Our novel optical design enables this UV cure system to deliver sufficient and consistent energy over a long working distance and fully cure epoxy impregnated fiberglass parts over a variety of shapes and sizes without having to individually tailor the cure parameters for each part. The system uses small high-power LED’s in a specialized and unique configuration, as a solid-state source, to provide a very robust and flexible cure system. This design is reconfigurable and can be either a hand-held “UV light brush” powered by a compact battery for small spaces or repair areas, or as part of a larger ‘plug-in’ portable system. The portable system automatically controls exposure and uses minimized floor and storage space. In both configurations the system is energy efficient, low power, light weight, with a very low heat load compared with current lamp technology.. The system is upgradeable and easy to maintain.

Title:UV/Thermal Optimized Rapid Epoxy Curing Source (ORECS)
Abstract:Between any graphite composite part that is in contact with aluminum in typical aerospace structures, there exists a fiberglass corrosion barrier isolation layer. New tighter mating tolerances require a different fabrication process. Current galvanic barrier restoration technology is labor intensive and cost ineffective. Therefore, the DoD requires a new source of radiation for rapid curing of the co-developed novel epoxy that is resistant to standard DoD aircraft fluids and environments. The U.S. Navy issued two solicitations to fulfill this need: one for resin and another for hardware. Responding to the call for hardware, Intelligent Optical Systems (IOS), with our vast experience in successful high- output LED-based systems, proposes to develop the novel UV/Thermal Optimized Rapid Epoxy Curing Source (ORECS). IOS will collaborate on the proposed ORECS project with Spectra Group Limited, Inc, (SGL), co-developer of the epoxy. IOS seeks to develop a superbright radiation source in a modular design. Each ORECS module will contain LED cells and will provide combined UV and thermal radiation for curing. These modules will be attached to each other and controlled so that the maximum range of part configurations and dimensions can be cured in the minimum time, saving time and money for the U.S. Navy.

Title:Cure System Equipment Optimization for Rapid Cure Epoxy Coated Fiberglass
Abstract:Ultraviolet (UV) cure materials and processing equipment have been used extensively in automotive and industrial applications, for decades. Several high-performance UV- curable resins and capital equipment have shown promise for use in military aircraft applications as a composite layer to restore the galvanic barrier, and also as a machining layer to achieve impossible to net-mold composite dimensional tolerances. It is the goal of this program to evaluate a new UV curing resin technology in cooperation with existing and next-generation UV cure lamps, conveyor and robotic curing systems. The use of rapidly cured UV composite materials promises to result in significant savings in fabrication time, cost, and repair of aircraft such as the F35 Lightning JSF. The purpose of this SBIR is to combine the expertise of UV cure equipment technology market-leaders with that of proven aerospace composite product development leaders – to demonstrate, manufacture, and commercialize qualified UV-cure equipment ready for transition to this production platform.

Title:Non-Mechanical LADAR for Improving The Helicopter Pilot’s Situational Awareness in Reduced Visual Cue Environments
Abstract:One of the major technical challenges of modern military and commercial rotary wing aviation is effective instrument aided navigation in brownout or whiteout conditions that can occur during landing or maneuvering in sandy, dusty, snowy or marine environments. Helicopter prop-wash churns up dense clouds of airborne particles that impede visibility. These conditions can escalate into crashing descents, lateral drift rollovers and collisions with ground features or obstacles. According to a recent Aviation Week & Space Technology article, “brownout has been blamed on the loss of more than 20 helicopters and 50 lives since 2001.” This illustrates a compelling need to develop and field in situ situational awareness sensors that can see through dust clouds and generate 3D terrain and obstacle maps of the landing zone in near real-time to provide active visual feedback to pilots during landing in brownout or whiteout conditions. Areté Associates and Vescent Photonics have teamed to provide a state-of-the-art dust penetrating laser radar (DUSPEN) technology to see-through brownout/whiteout conditions. Areté will marry its fiber laser based imaging lidar technology and our extensive experience in developing 3D imaging lidar systems for applications in highly turbid medium with a newly developed non-mechanical beam steering technology pioneered by Vescent Photonics. This combination of technologies and experience should result in a significant advancement in see-through situational awareness sensor technology.

Abstract:Bridger Photonics (BP) and collaborative partner Montana State University (MSU) propose to develop a completely novel, non-mechanical scanning mechanism that will enable a compact, high-resolution, imaging LADAR system for enhanced navigation aid during helicopter brownouts. Such systems are becoming prominent in today’s modernized military especially as the cost in lives and dollars has come to the Navy’s attention. LADAR imaging is needed for increased functionality including enhanced situational awareness, obstacle detection and avoidance during landing. Due to the demanding payload requirements, any enabling technology must be sufficiently rugged, compact and lightweight. BP’s proposed LADAR system will be capable of rapid volumetric scans with resolution up to 1 cm3 over a range of 30 m and a 30º x 60º field-of-view. The system will utilize an ultra-compact laser source, have no moving parts, and take advantage of a unique heterodyne detection technique to reduce receiver electronic bandwidths and processing requirements making the system robust, compact and affordable. The proposed system is based on BP’s recent innovations in controlling frequency-swept optical laser sources and utilizing these sources to provide a unique non-mechanically scanned, wavelength multiplexed imaging system.

Title:Mixed Gas Hypoxia Training in Low Pressure Chambers
Abstract:We must determine if we can incorporate our existing normobaric simulated altitude technology into a hypobaric chamber so that the chamber may first climb to 20,000 feet under normobaric mixed gas conditions, and then climb another 10,000 feet using low pressure, maintaining a steady 30,000 feet. Alternatively, we need to determine if we can we create a modular room adjacent to the hypobaric chamber that will allow students to experience 30,000 feet of simulated normobaric altitude? We believe that the answer to both of these questions is yes, we can. The first approach will require testing new oxygen sensors that can operate with our existing control system in a presurized environment. We will also test hoses, valves and seals that will allow our hypoxic air generators to perform without being damaged by the changes in pressure. In the second approach, we will need to design and develop a satisfactory altitude room that will be sealed sufficiently with an appropriate entry/exit system to allow for climbing to and maintaining 30,000 feet.

This breakthrough thermal image technology potentially offers next generation thermal camera performance attributes of: Large Pixel Array, Uncooled Operation, High Sensitivity, Fast Response and Low Cost. Leveraging this uncooled IR image technology developed in the past 7 years and in collaboration with Prof. Rana Biswas of Iowa State University, we propose a new improvement via incorporating micro-machined photonic crystal structure. This new design will simplify the manufacture process at the same time address the critical requirements of high sensitivity and extremely large dynamic range as well as multiple band operation for may critical military and commercial applications. The proposed imager will feature simultaneous dual-band MWIR/LWIR operation, high sensitivity, large dynamic range, megapixel resolution, uncooled operation, minimized weight, volume, power, and cost. During Phase I, the feasibility of the proposed technique approach will be demonstrated. A fully functional photonic crystal enhanced dual-band MWIR/LWIR imager will be prototyped in Phase II.

Title:Design and Optimization of Radar Systems to Assist Rotorcraft Piloting in Adverse Environments
Abstract:Rotorcraft are increasingly turning toward high-resolution Ka- through W-band radar sensors that can image terrain and obstructions but also see through the particulates that confound infrared and optical sensors, such as sand, ocean spray, and fog. As with any onboard sensor, designers must consider the antenna/platform interaction, and mature tools exist to address this type of problem. However, at these wavelengths, airborne vehicles can span several thousand wavelengths. This is well beyond the capability of any full-wave electromagnetic solver. While asymptotic techniques are practical here, they are powerless to model the antennas, themselves. We propose to investigate two novel techniques for integrating asymptotic and full-wave methods that can solve the end-to-end antenna/platform integration problem. One technique folds physical optics directly into method-of-moments to greatly expand the size of problem it can handle, but without compromising accuracy. The other splits the problem into small (full-wave) and large (asymptotic) regions, the novelty being the ease of integration that allows both solution regimes to fully couple. Phase I will focus on proof-of-concept and comparative evaluation of these two techniques. In Phase II, the more promising technique will be selected for full development, including a commercial-grade GUI.

CRG seeks to eliminate the complexity of current active systems through the use of CRG’s “smart” materials in shape memory polymer (SMP) based material systems. Design tools will be developed to computationally predict performance of morphing resonator concepts and provide a frame work to establish design methods to develop adaptive liners for all Navy aircraft. The morphing resonator concept will reduce broadband noise and tune absorption properties through flight regime changes. CRG will leverage much experience in morphing system design to realize the morphing resonator concept.

Title:Spontaneously Tunable Acoustic Smart Arrays
Abstract:To address the Navy need for an innovative tunable acoustic liner for aircraft engine noise reduction, Physical Optics Corporation (POC) proposes to develop new Spontaneously Tunable Acoustic Smart Arrays (STASA). They are based on a set of smart regulating structures , modifying noise attenuation characteristics according to aircraft flight regimes, takeoff, cruise (low, mid, high speeds), and landing. The innovation in STASA will enable the acoustic liner not only to reduce engine noise by >20 dB in a broadband range down to 1000 Hz, but also to reinforce structure integrity. We will apply POC’s adaptive control algorithms to provide tunable noise attenuation. STASA will be designed to use a low-oxidation material, robustly packaged for a lifetime >25 years and to avoid adverse infrared, fatigue, flutter, or engine performance effects. In Phase I POC will demonstrate the feasibility of STASA through design, simulation, development, and testing of a prototype acoustic liner. We will verify the simulation results and near-field performance. In Phase II, POC plans to develop a fieldable Phase II STASA prototype and demonstrate it in a simulated environment where a representative engine noise environment can be produced, resulting in both experimental evaluation and verification via proven computational methodologies.

Title:Development of a Piezoelectric Active Acoustic Liner for Jet Engine Noise Reduction
Abstract:Acoustic liners are presently used for attenuating combustion and turbine noise radiated from jet engines. Current acoustic liners are passive by nature. This is a drawback because they are only able to absorb acoustic energy over a limited bandwidth. A possible solution to this drawback is the development of an active acoustic liner. The main advantage of this concept is the ability to tune the acoustic impedance for optimal attenuation at variable operating conditions. In this proposal we outline the development of a piezoelectric acoustic liner that is capable of adapting its attenuation characteristics to the various flight regimes, thus making it a candidate for an active acoustic liner. The liner is active because an electrical excitation is applied to the piezoelectric element causing the porous face sheet to vibrate at a prescribed frequency and displacement. Preliminary results have demonstrated that the active liner can improve the absorption characteristics compared to a passive liner. To build upon these results, a computational model will be developed during Phase I to predict the acoustic absorption properties of the piezoelectric actuator and the perforated liner sheet. Then during option portion of Phase I, the computational model will be further developed and experiments will be run to optimize the liner performance.

Title:Metal Air Seawater Battery as the Power Source for High Power Long Endurance Sonobuoy and UAV Sonobuoy Applications
Abstract:After comparing various power sources, including primary lithium battery, metal air seawater battery and hydrogen fuel cell, we come to the conclusion that magnesium air seawater battery is the best choice for the sonobuoy applications in terms of specific energy, energy density, shelf life, system cost, reliability, and safety for personnel and host vehicle. In this SBIR program, leveraging on our technical achievements, metal air seawater battery will be further developed, produced and certified as the expendable power source for long endurance sonobuoy and UAV sonobuoy applications. The initial analysis suggests that this system could provide over 7 times longer running time than current Mg/AgCl activation battery. The objectives of the program is to develop a lightweight, long endurance, high power output, low cost sonobuoy and Unmanned Aerial System (UAS) battery to replace current chemistry and extend the endurance given the volume, weight and safety constraints.

Title:Long Endurance, High Power Battery
Abstract:Maxpower Inc. is proposing the replacement of the present UAV-Sonobouy battery chemistry with a novel high power Lithium Monofluoride[Li/(CF)n] system. Though historically used in low power applications, Maxpower has proven that Li/(CF)n systems can meet high power requirements by combining proprietary thin cathode technology with a highly porous electrospun separator. Projections based upon lab scale tests show that a 20% reduction in volume and a 33% increase in flight time can be achieved with this new system. If implemented, the Li/(CF)n chemistry will eliminate the consumption of silver in the current Magnesium/Silver-Chloride system, offering a significant reduction raw material costs.

Abstract:The purpose of this proposal is to demonstrate the effectiveness of using Acree Technology’s erosion resistant coating to protect large-size turbine engine compressor airfoils for the F-35 Joint Strike Fighter Short Take-Off and Vertical Landing (STOVL) aircraft. The JSF STOVL compressor airfoils for both the LiftFan and the F-135 engine are constructed using integrally bladed rotors that can be over a 1 meter in diameter. Acree’s erosion resistant coating has been extensively tested in previous projects and is currently at Technology Readiness Level (TRL) 6. Acree has large deposition chambers for applying our erosion resistant coating that are well suited for coating the JSF airfoils.

Title:Erosion Resistant Coatings for Large Size Gas Turbine Engine Compressor Airfoils
Abstract:Jet engine titanium compressor airfoils are susceptible to erosion damage ranging from a few percent loss in blade chord length in fighter engines to more significant erosion exhibited by helicopter engines operating in desert environments. The application of titanium nitride coatings on individual compressor airfoils have provided significant operational, maintenance and safety benefits for helicopter engines operating in desert environments. Yet, this technology has not been applied on large integrally bladed compressor rotors due to the challenge of coating large parts with diameters greater than 0.4 m and the more subtle erosion characteristic of jet engine compressor airfoils as compared to helicopter engines. However, a few percent chord loss in a titanium, integrally bladed compressor rotor is signicant in that the repair and replacement costs are much more expensive than for individual airfoils. Additionally, a few percent in chord loss decreases compressor performance and increases fuel consumption. The application of erosion resistant coatings on large, titanium compressor integrally bladed rotors via a cathodic arc physical vapor deposition process utilizing machines with sufficient coating capacity could potentially provide the necessary erosion protection within specified fatigue debit limits; hence, increasing the mean-time-between-repair interval, maintaining compressor performance and decreasing fuel consumption.

Title:Development of Multifunctional Erosion-Damping Coating Systems and Application Methods for IBRs and Blisks
Abstract:In this Phase I effort, new advanced multifunctional thin-layered erosion-resistant (ERC) systems and process technologies will be developed. The goal of the research is to develop innovative and advanced multifunctional damping coating systems in thin layer configurations not only to enhance high damping for prevention of HCF but also to significantly improve resistance to erosion. An additional goal is to further enhance fatigue strength of gas turbine compressor IBRs or blisks in harsh sand ingestion and/or combustion gas environments. The advanced multifunctional erosion-resistant damping coating system consists of a duplex coating system which consists of a top coat, a state- of-the-art multi-layered erosion resistant coating and a bond coat, our damping coating system. The damping bond coating can be seen as a soft core supporting a hard outer surface (ERC). The combination of a hard surface and a soft interior has been greatly valued in modern engineering because it can withstand very high stress and fatigue which thus acts as a damage barrier to prevent crack penetration into the substrate from ERC and to arrest cracks initiated from the substrate.

Title:Erosion Resistant and Damping Coating for Large Size Gas Turbine Engine Compressor Airfoil
Abstract:The Joint Strike Fighter Short Take-off and Vertical Landing (STOVL) aircraft will operate in desert environments and ingest abrasive particles during the critical take-off and landing stages of operation. Under such conditions, the compressor airfoils on the JSF STOVL aircraft’s integrally bladed rotors (IBR) for both the lift-fan and cruise engines may get damaged which can lead to poor engine performance and potential failure. Since these IBRs are relatively large, it would be expensive to manufacture and replace. UES, Inc. proposes to develop erosion resistant coatings to maintain IBRs’ performance (efficiency) and to delay its degradation due to sand erosion. The developed coatings will be evaluated in terms of erosion resistance and damping. Based on such evaluations the coatings will be ranked. Highly ranked coatings will be further developed in Phase II.

Title:Relative Ultra Tight IMU/GPS Integration
Abstract:Intelligent Automation Inc. (IAI) proposes a novel ultra tightly integrated IMU/GPS system where two or more integrated IMU/GPS units send their raw observation as well as IMU measurements for relative positioning. In this proposed method we develop a new GPS receiver based on IAI’s Cooperative RAKE receiver that is capable of significantly reducing the effect of multipath induced error by tracking each discernable multipath and line of sight signal on each RAKE finger independently. In addition to this, the integrated IMU/GPS algorithm uses the PLL tracking loop to generate and track GPS signal. Once a GPS satellite (channel) is lost this generated GPS signal will be used as the input to the receiver so that the PLL continuously track the lost channel. This allows a very narrowband filter for the PLL with very fast carrier recovery and tracking when the lost channel is regained. Even in the case of total GPS blackout a high accuracy IMU is used for generating GPS signal for the input of the receiver for an interval of time which depends on the performance of the IMU.

Abstract:The Navy Unmanned Combat Air System (N-UCAS) vision is to develop a weapon delivery system that expands tactical mission options and provides revolutionary new air power and penetrating surveillance capability. Key to the N-UCAS mission is the ability to perform precision autonomous navigation, even in GPS-denied environments. Under a current contract with the Navy, NAVSYS is developing a method of improving the existing Relative Navigation (RELNAV) functionality in Link-16 terminals to operate with near-GPS quality by embedding a virtual atomic reference clock that is common across all “Server” terminals. These Server terminals can then provide Precision-RELNAV (P-RELNAV) services to “Client” terminals in jammed environments. Under this SBIR effort, we propose to develop a P-RELNAV application suitable for use with other tactical data links that will be used by N-UCAS. Leveraging our recent work GPS-NAP and RELNAV work, an integrated GPS/TOA/INS Receiver Autonomous Integrity Monitoring (GTI-RAIM) algorithm and navigation filter will also be developed that will gracefully integrate RELNAV measurements with existing GPS-INS measurements to provide a robust navigation solution.

Title:Cross-Cockpit Collimated Displays for Flight Simulation
Abstract:At present, multi-viewer cockpit displays that provide accurate collimation and consistency of other display characteristics, such as intensity and tint, require expensive projection systems. The capability to accomplishing these functions with PC based software would provide both reduced cost and flexibility. Not only would less expensive projectors be required, such software executed on a PC using a GPU would be able to be tuned to any selected projection systems. The sophistication of GPU based graphics on PCs permits modification of the image input to the projection system such that images by multiple projectors can be made to be collimated, have equal intensity, have equal tint, and in general, proved a seamless combined image. DVC has five years of experience using GPU based software for image generation. This experience will permit DVC to develop software for the control of cross-cockpit displays that permit a seamless display with multiple projectors. In addition, nonlinear optimization techniques provide the capability to obtain both collimation and consistency of color and intensity across the entire scene automatically, that is, rapidly and without human intervention. These optimization methods are well known in both the mathematical and engineering communities

Title:Cross-Cockpit Collimated Displays for Flight Simulation
Abstract:Current simulator cross-cockpit displays offering large field of view, multi-viewer (two or more), collimated displays are expensive and have a number of performance and viewing deficiencies such as irregular geometry, heavy weight, high cost and finally poor vergence and collimation. Some of these problems become apparent in a number of ways such as difficulties in maintenance setup caused by irregularities in the display and color drop off and sometimes even motion sickness and pilot headaches. The optical properties of present day systems work on the ‘assumption‘ that the mirror is perfectly spherical when we know that this is not the case. Working on this erroneous assumption,the shape and size of the back projection screen is calculated. When these two major components ( mirror and back projection screen) are brought together to form the complete optical system the anomalies in the curvature of the mirror become evident in the display by way of edge compression and other visual distortions. Poor system performance can have a detrimental impact on training as is termed ‘negative training’ as it destroys the ‘illusion’ that the training provider is attempting to generate by reminding the pilot that it is ‘only pretend’.

Title:Improved LADAR
Abstract:Visually degraded environment (VDE) conditions pose a threat to Navy and Marine Corps helicopter by dramatically decreasing pilots’ situational awareness. Brownout and whiteout conditions are especially dangerous. Sensors such as laser radar (LADAR) imaging sensors can see through dust, snow and fog by gating past obscurants, but in order to provide the pilot with imagery that most closely resembles what is outside the aircraft, the spatial resolution, range accuracy, and fields of view of existing LADARs must be improved. We will address this by improving an already state-of-the-art real-time flash LADAR system built by Ball Aerospace. We will improve LADAR resolution by fusing its 3D information with 2D information from a high-resolution infrared or visual camera or from an obscurant-penetrating millimeter wave radar, producing resolution on the order of a megapixel visible camera. We will improve range resolution using variable offset delays and intelligent interpolation. We will improve the LADAR’s field of view using wide field- of-view optics and a non-inertial scanning system such as counter-rotating Risley prisms. Our improvements will be applied in real time and produce imagery comparable to what the pilot would see outside the helicopter.

Title:Multi-Sensor Based Superresolution Hyperspectral Imaging Ladar System
Abstract:To address the Navy’s need for an innovative laser radar image and data processing technology for helicopter vertical lift in visually degraded environments (VDEs), Physical Optics Corporation (POC) proposes to develop a new Multisensor-based Superresolution Hyperspectral Imaging Ladar (MSHIL) system. This MSHIL system is based on an innovative sensor fusion of gated laser radar, visual and video sensors for multiband spectral detection, hyperspectral imagery, and multiframe superresolution technologies. This system offers: 1) high image and range resolutions (over 1,024 x 720 pixels and within centimeters for a 100 to 1,000 ft range); 2) wide FOV of over 60 degrees x 120 degrees; 3) real-time operation (over 1,000 image correlations per second); 4) compactness, light weight, and low power consumption; and 5) reliability with over 99% probability of detection. In Phase I POC will demonstrate the feasibility of the MSHIL system by defining system requirements and architecture design, conducting software simulation, and assembling a scaled-down TRL 4 MSHIL system prototype. In Phase II POC will develop a MSHIL engineering prototype system and demonstrate its capability for real-time high-resolution wide-FOV helicopter operations.

Title:Rapid Deposition of Uniform Thickness Fiber Interfaces in Bulk Fabric for CMC Toughening
Abstract:Physical Sciences Inc. will develop a BN/Si3N4 fiber interface coating that can be applied uniformly to fibers in a woven fabric and provide toughening in SiC fiber reinforced ceramic matrix composites (CMCs). Using traditional CVD precursors such as BCl3, NH3, and SiCl4, we will demonstrate a rapid, self-limiting, scalable vapor phase deposition process to create coatings of uniform thickness throughout the tows. Due to the improved uniformity of the fiber coating, the interface thickness can be reduced, increasing the flexibility of the fabric and ease of handling. We will fabricate a CMC plate from the coated fabric, measure the composite strength to verify toughening, and provide a conceptual design for a commercial-scale reactor to coat full bolts of fabric. During Phase II, we will optimize the thickness, composition, and morphology of the coating and will perform more extensive materials testing including stress oxidation. More uniform, thinner interfaces will improve the high temperature performance and reduce the manufacturing costs of CMCs for long-life applications in advanced propulsion components.

Title:Advanced Process Schemes for Improvement of the Dimensional Stability of Ceramic Matrix Composites
Abstract:Ceramic matrix composites (CMC) are being developed for turbine engine exhaust structures on the Joint Strike Fighter (JSF) and other advanced military platforms. One of the primary candidate material systems for manufacturing components in the exhaust structure is a polymer-derived matrix composite that uses a silicon carbide based fiber reinforcement. These CMC components can be complex shapes that require very precise dimensional tolerances. Deviations from as-molded and machined dimensions as a result of thermal excursions during processing can result in rejected parts. The aim of this program is to develop a modified processing scheme that will eliminate this particular problem. In order to achieve this goal, we will focus on the conditioning of the fiber reinforcement. Precise control of the thermal history of the reinforcement will result in improved dimensional stability. As a provider of interface coatings used in this type of ceramic composite, we will also investigate the effects of applying the interface coating before and after conditioning of the fiber reinforcement. The addition of this conditioning process step is expected to both reduce costs (as a result of higher yield) and improve the lifetime of the part.

Title:Variable Speed Speech Synthesis
Abstract:The objective of this proposal is to demonstrate the feasibility of developing variable speed speech synthesis technology. We plan to use open source TTS systems because they often provide flexibility and interoperability, which is essential for research oriented work. To modify speaking speed, we plan to focus on time domain time-scale modification algorithms, which provide good quality with less computational complexity compared to other approaches such as sinusoidal models or vocoder-based approaches. We will test time domain methods including SOLA, PSOLA, and WSOLA. We will apply linear scaling factor, which modifies the duration regardless of whether the speech segment is a silence, a transient or a sustained vowel. We will also apply different scaling factors to different parts of speech segments. During the optional six months, we will focus on creating multiple voices by modifying voice types, gender, dialects (accents), and perceived emotion of the speech. Based on the source-filter models, we will investigate algorithms for modifying source and filter characteristics, from which many different voices can be generated.

Title:APE Segmentation for Variable Speed Speech Synthesis
Abstract:We propose to apply proprietary technology to meet the needs of variable speed speech synthesis. Our approach involves a new method of sound segmentation that provides not only greater control of speech timing, but extensive control and variability of all manner of prosodic features, including intonation and accent, without undue degradation to sound quality and intelligibility. Current systems fail to provide these adequately, because of the methods by which units are selected, stored, and recalled for concatenation; the means by which these units are manipulated; and the absence of requisite markup standards for control of prosody in synthesis. The final deliverable of this project will be a stand-alone software package capable of providing the end-user variable control of speech rate in synthesis, as well as integration of this functionality as a module in a new generation of off-the-shelf speech synthesis engines.

Title:Very Rapid Cure Capable Resin and Optimization for Pre-Preg Process Development of Barrier or Isolation Ply Materials
Abstract:This proposal is for the development of a rapid cure resin system to be used as a galvanic barrier or isolation ply application on carbon fiber composite constructions. The galvanic barrier is composed of a UV curable resin used to make a pre-preg system with E-glass, 108-style fiberglass cloth. A UV cure resin is proposed with the use of high temperature and low dielectric cyanate ester monomers and oligomers. The cyanate esters will be copolymerized with epoxy, epoxy acrylate, novolac and bismaleimide monomers and oligomers to control Tg, viscosity, rate of cure and adhesion to the glass cloth and substrate. The UV catalyst for curing the cyanate ester formulations will be the type that produces a Lewis acid such as a sulfonium or oxonium type. The Tg and cure state of the resins will be evaluated by DSC. The resulting composite will be tested for elastic modulus, tensile strength and resin content.

Title:Very Rapid Cure Capable Resin and Optimization for Pre-Preg Process Development of Barrier or Isolation Ply Materials
Abstract:Ultraviolet (UV) cure materials have been used extensively in automotive and industrial applications, for decades. Several high-performance UV-curable resins have shown promise for use in military aircraft applications as a composite layer to restore the galvanic barrier, and also as a machining layer to achieve impossible to net-mold composite dimensional tolerances. It is the goal of this program to evaluate a new UV curing resin technology. This program will determine baseline properties and allow optimization of the UV resin chemistry to achieve high glass transition (Tg) temperatures and a good balance of mechanical properties. The rapidly cured UV composite materials promise to result in significant savings in fabrication time, cost, and repair of aircraft such as the F35 Lightning JSF. The purpose of this SBIR is to combine the expertise of UV cure researchers with that of proven aerospace composite product development leaders – to demonstrate, manufacture, and commercialize a qualified UV-cure Epoxy-Fiberglass prepreg product for transition to this production platform.

Title:Very Rapid Cure Capable Resin and Optimization for Pre-Preg Process Development of Barrier or Isolation Ply Materials
Abstract:Current production methods for the composite galvanic isolation ply on the F-35 requires too much time for fabrication and are excessively expensive. TRI/Austin proposes to develop and test unique rapidly curing ultraviolet matrix resins producing innovative high performance, ambient storable, prepreg compositions for the F-35 program and ancillary future applications such as aircraft composite repair. A systematic development and testing program will result in a unique prepreg composition that cures within five minutes and produces a very high glass transition temperature composite. Experimental design techniques to be utilized will systematically evaluate formulation and processing components resulting in a low cost, rapid curing, well adhered, environmentally benign, and chemically resistant isolation ply. The effectiveness of our technical approach will be demonstrated in the course of laboratory based testing including glass transition temperature, cure time, resistance to typical aerospace fluids, weight, density, and thickness. This systematic approach has been proven to be the most effective method for the development of new materials and processes. Throughout the Phase I and II, TRI/Austin will work in cooperation with a prepreg manufacturer and the awardees of topic NAVY 08-137. Immediate benefits of this endeavor for the F-35 program are reduced costs, manhours, and increased production.

Title:FindMe™ Radio: Innovative Non-GPS Geolocation System for Sonobuoys
Abstract:The Navy has identified a need for the ability to locate a network of sonobuoy sensors that does not require GPS (Global Positioning System). Commercially, NanoVision Technologies, Inc. is leading efforts to provide geolocation and weather information to aircraft, boats and trucking industries using inexpensive but reliable miniature, extremely low power solutions. NanoVision is developing a new, revolutionary geolocation technology called the FindMe™ Radio. The FindMe™ Radio technology utilizes a combination of several key technologies that overcome the limitations of GPS (Global Positioning System) to achieve geolocation anywhere, indoor or outdoor. We will examine Radio Direction Finding (RDF) / TDOA (Time Difference of Arrival) based approach and contrast this approach with Distance Measuring Radio (DMR) to identify the best possible solution for geolocation of sonobuoys with minimum impact to the current sonobuoy architecture. Current RDF techniques do not have the accuracy to reliably isolate multiple radio transmissions. In contrast, our FindMe™ Radio approach utilizes innovative TDOA technology that overcomes the need for large bandwidth, at least three measurements, and precisely known antenna locations. Likewise, our DMR technology provides superior accuracy using miniature, low-power wideband pulses with low probability of intercept (LPI/D). Under this SBIR, we plan to research each of these approaches to determine the best approach for sonobuoy applications.

Title:Non-GPS Sonobouy Positioning System
Abstract:Quick and accurate sonobuoy location is becoming more critical in the airborne ASW problem as multi-static active search systems and data fusion techniques play more dominant roles. Sonobuoy locations must be determined automatically and constantly updated in order to estimate target locations as soon as target detection clues are available to the acoustic subsystem. Obsolete methods of buoy location such as “Mark- on-Top”, and systems based on assumptions that the target will be held in contact for significant periods will not work. In Phase I, RDA proposes techniques that can be used to automatically locate sonobuoys by extracting information from the sonobuoy signals. Techniques include Angle-of-Arrival (AOA), and Doppler extraction. The AOA approach is applicable to multi-antenna sonobuoy receiving systems, whereas the Doppler extraction approach requires only a single antenna to produce the sonobuoy location. The techniques can also be combined to provide a comprehensive sonobuoy location system. The techniques address the various sonobuoy types and consider the real-world constraints and parameters, and performance is modeled in MATLAB. Preliminary design for a prototype and definition of a transition path to fleet avionics is also part of the Phase I.

Abstract:Areté Associates (Areté) proposes to develop advanced algorithms for landing area characterization from LADAR data for the purpose of assisting helicopter landing during brownout. Our algorithms will discriminate ground from non-ground objects; remove outlier data; identify flat areas/pits/trenches; and characterize level, uncluttered areas suitable for a helicopter landing zone. These processed data can then be distributed to a fleet of helicopters to plan a safe landing for each vehicle.

Title:System for Multi-Ship Brown-Out Helicopter Landings
Abstract:Brownout is the number one operational problem facing military rotorcraft today. Visual obscuration, combined with nose-up attitude during landing, make identification of landing area hazards difficult or impossible. Landing multiple helicopters is even more difficult, since the trailing aircraft must contend with the dust cloud resulting from landing the lead aircraft. To address this problem, CG2 is proposing a system that combines data from a LIDAR sensor and CCD or IR cameras mounted on the lead aircraft with user input regarding the flight profile parameters and telemetry from each of the aircraft in the formation to produce recommended flight profiles and synthetic vision displays that allow all of the aircraft to land safely. The system will generate a virtual scene using geometry extracted from the LIDAR data combined with correlated camera imagery so that objects may be identified more easily. The aircraft telemetry will be used to render a real-time scene that accurately depicts the position and orientation of each ship relative to the terrain, with a choice of viewpoints. The solution will be validated in a simulation environment as well as with real sensors, and be capable of running on ruggedized, embedded hardware.

Title:Dynamic LADAR Terrain Generation System for Multi-ship Rotorcraft Brown-out Landings
Abstract:TerraMetrics, Inc., proposes to demonstrate a key architecture and processing methodology that provides a direct solution for multi-aircraft formation helicopter landings in blinding brown-out conditions. The proposed innovation offers a synthetic vision implementation that self-generates, shares and displays a compact landing zone 3D terrain/obstacle model, and multi-aircraft approach and landing routes using lead-aircraft Laser Detection and Ranging (LADAR) sensor data, and formation aircraft location and motion vector data. Our approach, referred to as TerraBlocks™ Clear-to- Land™/MultiView, builds on our TerraBlocks™ Clear-to-Land™ self-generating dynamic 3D terrain model technology coupled with our TerraBlocks™ synthetic vision (SV) rendering and display engine. The focus is our cloud-to-surface methodology for propagating voluminous LADAR point cloud data into a compact, multi-resolution, real-time- displayable parametric heightfield surface model representation where ground and airborne obstacles are clearly displayed as “no-fly” volume features. The approach improves wire feature discrimination and retention against ground and primary features. Once received by each aircraft in the formation, the terrain/obstacle model and computed route plans, coupled with the continuous position and motion vector data from each aircraft, is displayed using the TerraBlocks™ SV system throughout the formation approach and landing maneuvers, providing all pilots with a robust situational awareness instrument for brown-out landings.

Title:Digital Method for Improved Custom Hearing Protection Equipment
Abstract:The DoD spends over $1 Billion annually on disability payments attributed to hearing loss, yet this can be prevented. Research shows that with proper hearing protection a 19% reduction in hearing loss cases can be expected. Custom ear plugs force the user to wear the devices correctly and to retain hearing protection during activity, thus eliminating improper seating issues as the primary cause of DoD hearing loss cases. Realization of custom ear plugs within the DoD has been slow because current manual/physical ear impression technology is difficult to implement on a large scale therefore a new means of acquiring ear impressions is required. A non-contact digital ear imaging/fabrication device is proposed here which would reduce DoD disability payments by a projected $190 Million per year.

Title:Digital Method for Improved Custom Hearing Protection Equipment
Abstract:Custom fitting hearing protection ear plugs have been shown to provide substantial benefits for personnel working in high noise environments such as around military aircraft and in a range of other war fighter and civilian industrial scenarios. Current manufacturing processes for shaping custom ear plugs require that physical impressions be taken of customers ear canals. Since this involves injecting silicone material directly into the ear, physical impression taking can be uncomfortable for the customer and yield results which will vary with the skill and technique of the practitioner. The focus of this Phase I program is to develop new means, based on Computed Tomography (CT) imaging technology, for capturing ear anatomy information without the need for physical impressions. Eliminating the physical impression will also eliminate the associated discomfort and variability and lead to more satisfied customers getting more reliable hearing protection. This Phase I program will further demonstrate initial feasibility of completing a custom earplug manufacturing process using only digital data, starting from a non-invasive CT scan through production to a finished hearing protector product. A report describing the approach and initial demonstration of the new capabilities will be provided at the conclusion of this work.

Title:Automated System for Digital Measurements of Ear Canal Geometry
Abstract:The widespread incidence of hearing loss in veterans throughout the Armed Forces, coupled with the lack of compliance with earplug usage guidelines for active personnel, necessitates a new approach to hearing protection. When properly fitted and worn, custom earplugs have the potential to provide consistent, reliable hearing protection. Creare proposes to develop a new technological approach that will improve the fit while reducing the logistics burden associated with custom earplugs, and so facilitate the widespread deployment of these earplugs in the Navy. This work will include the development of new techniques for accurately measuring individual ear anatomy; balancing trade-offs between hearing protection and individual comfort levels; creation of a digital database of ear canal geometries to be used to evaluate variation in anatomic shape and its impact on earplug design and effectiveness; and the ability to digitally transmit, archive and retrieve anatomic data. In addition, we will develop methods to quantify changes in aural anatomy that occur over time.

Additionally, the portable MRI device will allow the user to manipulate and manage captured data for archival, adjustment, and statistical study. The portable MRI device will also provide significant improvements to hearing aid manufacturers by reducing the time to manufacture hearing aids, allowing custom adjustments prior to costly fabrication processes, management of patient data without the logistics associated with mold model storage and filing, as well as statistical monitoring of patient physiology.

Abstract:To address the Navy need for a more accurate and robust digital technology for the measurement of ear canal geometry and improvement of the fit and noise attenuation of individual earplugs for flight deck teams, Physical Optics Corporation (POC) proposes to develop a new Digital Ear Canal Scanning Technology (DECST). This non-contact, not ionizing technology is based on en-face Optical Coherent Tomography. The innovations in optical design and image processing algorithms will enable measuring ear canal geometry in less than three minutes with an accuracy better than 0.01 mm, and mapping the underlying tissues. This digital technology will allow improved computer earplug design, easy data dissemination and archiving, and onsite earplug fabrication using already developed digital stereo-lithography. It will greatly reduce the logistic burden associated with equipment maintenance for crew noise protection. In Phase I, POC will demonstrate the DECST feasibility by the design, assembly, and demonstration of operation of the experimental prototype. In Phase II, POC plans to develop an engineering prototype and obtain protocol approval for testing the prototype operation on humans.

Title:A Novel Test Method for Measuring Interlaminar Tensile Strength of Ceramic Matrix Composites at High Temperature
Abstract:The use of ceramic matrix composite (CMC) materials in aero-engine hot-section components has grown substantially over recent decades. Attributes that make these materials attractive to aero-engine designers include their lower specific weight, higher creep resistance, higher thermoshock resistance and higher specific strength over a large temperature range in comparison to superalloys and greater damage tolerance in comparison to monolithic ceramics. However, there remains a great deal of uncertainty regarding the strength properties of CMCs at high temperatures due in large part to a lack of standardized test protocols applicable to high temperatures. In particular, there exists no test method that enables accurate measurements of the interlaminar tesnsile strength of CMC material at high temperatures. To address this shortcoming, Composite Technology Development (CTD) proposes the development of a novel test protocol that enables accurate and reliable measurement of interlaminar tensile strength of CMC material at temperatures up to 2300oF. The proposed test protocol will utilize a non- contact heating method that enables quick and efficient heating up to the target temperature of 2300oF. The proposed test protocol will also allow for test samples to be prepared from existing stock of thin-gage, aero-section-hot-component-relevant CMC material thereby making custom test sample manufacture unnecessary.

Title:Innovative Approaches for Evaluating Interlaminar Tensile Strength of Ceramic Matrix Composites (CMCs) at Elevated Temperatures
Abstract:Hot structures fabricated from CMCs are an attractive design option for specialized components of future military aerospace vehicles and propulsion systems to reduce weight and increase survivability. However, thermal-structural components fabricated from CMCs suffer from inadequate interlaminar strength, thereby increasing their vulnerability to delamination when subjected to high through-thickness thermal gradients, acoustic/high cycle fatigue, impact damage, and/or applied normal loads. Although there are Industry standards for Interlaminar Shear strength testing, no such consensus exists for Interlaminar Tension [ILT] strength testing – particularly at elevated temperatures. Better test methods are needed to characterize the interlaminar strength of CMCs to facilitate the design of efficient structures, reduce the risk of premature hardware failures, and support production Quality Assurance. Hyper-Therm HTC is proposing an innovative approach for measuring the elevated temperature ILT strength of CMCs. The test configuration directly applies an interlaminar tension force to the midplane of the laminate thereby creating a clean, ILT stress state in the specimen that does not require knowledge of the interlaminar properties in order to calculate the failure stress. Specimens can be fabricated inexpensively from flat plate stock, and because the test method does not require adhesive bonding, it can be used at temperatures up to 4000°F.

Title:High-temperature CMC Processing for Ceramic-to-Ceramic Joining and for Interlaminar Strength Evaluation
Abstract:There is a strong need to develop and demonstrate inter-laminar tension test methods for CMC at high temperatures in NAVY JSF Program for aero-engine components. MATECH GSM (MG) proposes to address this need by employing a variety of innovative low-cost pre-ceramic polymer-derived high temperature CMC adhesives between CMC test coupons and push rods. MG’s high-temperature CMC adhesives are designed to facilitate ceramic-to-ceramic joining for the purpose of evaluating high temperature interlaminar strengths. Traditionally, joining adhesives are mainly developed for bonding two dissimilar materials; hence its structural performances, particularly off-axis behaviors accompanied by a necessity of non-brittle failure are mostly neglected. The CMC adhesives proposed here is a ceramic matrix composite that demonstrates graceful failure but is stronger than that of the test-coupons. Due to the two already existing given materials of the test- coupon and fixture, the newly added third material must be as physically close as possible to the other two materials from the beginning. The PIP CMC processing is only one densification method among several ceramic matrix formation routes that meet this first requirement. It is low-cost, a variety of active/non-active fillers can easily be added, and it is capable of forming shapes at low temperatures.

Title:Interlaminar Tensile Strength Testing of CMCs at High Temperatures Enabled by Oxidation Resistant Ceramic Cement Derived from ZrB2-SiC Precursor
Abstract:Continuous fiber reinforced ceramic matrix composites (CMCs) are desired for aerospace applications due to the strength and toughness imparted by incorporation of embedded long fibers of carbon or silicon carbide into a ceramic matrix. Oxidative degradation at high temperature is the predominant factor limiting the use of CMCs in jet engine applications. The components can swell when heated in air, which suggests poor interlaminar tensile (ILT) strength. A method for measurement of ILT strength of CMCs at the high temperatures to which they are exposed (2300 °F) is highly desired by engine developers and the composites R&D community, but extension of the testing standard is not possible without development of an ultrahigh temperature adhesive. This program will utilize a new high-yield ZrB2 ceramic derived from polymer precursor to demonstrate the feasibility of using a ceramic cement to enable ILT strength testing at high temperature in air. Thor Technologies has teamed with the Materials Engineering Group of Southern Research Institute and a provider of SiC test fixtures to plan and execute the following proposed effort, which will combine the new precursor with appropriate additives for surface fluxing, to achieve reactive bonding of the cement to the CMC surface.

Title:Real-time Spectral Band Optimization for Unmanned Aerial Systems (UAS) Hyperspectral Camera
Abstract:To meet the need of the Navy in a hyperspectral imaging system with an automated analysis algorithm for optimum detection of specified target features, Applied Science Innovations, Inc. proposes development of the Coded-Aperture Hyperspectral Imager with Real-time Spectral Band Optimization (CAHIRSO). Communication channels of small tactical unmanned aerial systems (UAS) fall short of the bandwidth requirement of existing hyperspectral imaging systems. Communication hardware with adequate bandwidth exceeds the volume and weight allowance of such UAS. The patent-pending CAHIRSO hyperspectral camera with image formation and spectral selectivity will automatically control the type and amount of data to be transferred to the ground, in near real-time. The complete imaging system will be contained in a 4.75 inch diameter by 12 inch in length cylinder or smaller package. The spectrum coverage will be from 350 nm to 1.7 micron, with automatic gain control, manual gain control (addressable), selectable bandwidth, feature extraction, and low power. Phase I will establish feasibility of the CAHIRSO concept. In Phase II, a functional pre-production CAHIRSO prototype will be developed, demonstrated, and delivered to the Navy for evaluation and use, ready for UAS installation. In Phase III, CAHIRSO design will be further developed for integration on board UAS.

Abstract:This effort develops a design for an integrated near real-time solution capable of determining optimal multi-spectral bands for target detection, storing complete mission data, and parsing resultant data and metadata for transmission of hyperspectral imaging results. This design, referred to as the “Optimized Hyperspectral Camera System” (OHCS), will leverage DSPCon’s new BFX architecture minimizing Size, Weight, and Power (SWAP), with Sarnoff’s world-class, innovative spectral analysis algorithms that can distinguish targets from clutter, even with minimal a priori target information and no a priori clutter information. OHCS will provide an unprecedented combination of performance and minimal SWAP to accommodate demanding Unmanned Aerial System (UAS) constraints. The design resulting from this SBIR will have a combination of performance + "Size, Weight, and Power" (SWAP) which is unachievable using any other standard available in the world today. DSPCon will create the OHCS hardware design with a company-developed architecture standard, called BFX, that is geared toward rapidly implementing systems involving any combination of data acquisition, processing and archiving functions in small form factor, light weight packages. The standard is based on high performance, modular (plug and play), small footprint, rugged, air-cooled or conduction-cooled, function-specific boards that communicate over a high speed serial I/O fabric. This approach enables the design to meet the needs of environments where minimizing SWAP is critical, as is allowing easy upgrades and expansion of system capacity with a plug-and-play structure.

Title:W-Band Power Amplifier Based on Wide Bandgap Technology
Abstract:Battlefield requirements for radar which can see through clouds, fog and smoke can be effectively met by using W-band systems. These systems require high power amplifiers to create the high level RF signal which is transmitted at the target. Current solutions rely on gallium arsenide (GaAs) or indium phosphide (InP) for the high power amplifier (HPA). This is due to the high transition frequency (Ft) of these materials. However, the power density of these materials require the use large device sizes to achieve a desired output power. This results in less efficient HPAs. As a result, these devices do not meet future requirements. Millimeter-wave active antenna arrays and radar transmitters offer superior performance when compared to lower frequency radars such as X-Band The goal of this program is to prove the feasibility of a 94GHz GaN based high power amplifier. Program Technical Goals: • Achieve 4-5 Watts/mm device level power density. • Demonstrate 25% device power added efficiency. • HPA with 5 Watts output power. • HPA with 25dB gain. • HPA with at least 15% PAE. MMICMAN will leverage existing production of S, X and Ka-Band GaN-based MMIC HPAs to achieve this goal.

Abstract:Millimeter-wave radars, operating in W-band centered at the 94 GHz low atmospheric attenuation window, provide advantages of high resolution with small antenna, penetration through fog, clouds, smoke, and dust. This program is aimed at the development of state-of-the-art high power solid-state power amplifiers for use in W- band active antenna arrays and radar transmitters. QuinStar Technology teamed with HRL proposes to develop an SSPA capable of >5W output with >25 dB gain, >15% power added efficiency by utilizing GaN MMIC technology. In Phase I, starting with the W-band MMIC cell device which HRL has demonstrated 2W/mm output power capability, we will investigate the feasibility of achieving >4W/mm power density by optimizing material and device parameters by means of simulation analysis. We will then develop a preliminary MMIC design by combining cells on chip to achieve 1.5W per MMIC chip with reasonable process yield. To achieve >5W output power, we propose to develop an amplifier design with high efficiency (low loss) 4-way combiner, which QuinStar has recently demonstrated <0.2 dB combining loss. The proposed Phase I effort will lead to the development and demonstration of >5W amplifiers in phase II that will enable W-band active array and radar transmitter development.

Title:Helmet Mounted Display (HMD) Symbology for Rotocraft Degraded Visual Environments
Abstract:“Brownout” is a dangerous phenomenon in which a rotorcraft’s downwash creates its own degraded visual environment (DVE) by throwing dust, sand, and other loose debris into the air around the aircraft, severely limiting or obscuring the pilots’ view of the landing environment. During a recent fiscal year, the U.S. Army determined that 75% of aviation Class A mishaps in Operation Iraqi Freedom were attributed to this phenomenon. The objective of this research effort is to determine the feasibility of integrating symbology into a helmet-mounted display (HMD) to aid rotorcraft pilots in day/night brownout/DVE conditions, and identify the steps needed to develop this technology for aviation applications. The feasibility of such an approach depends on the development of effective, intuitive HMD symbology that provides the pilot with the data required to facilitate rotorcraft landing operations. One of the challenges of this development will be determining and mitigating the effects of the expected wide variations in day/night brownout/DVE background condition against which the HMD symbology will be viewed. HMD display symbology for this application must provide high contrast against the background, with low intensity and eye strain, particularly with night vision devices.

Title:Holographic Brownout Condition Adaptive Symbology System for Day/Night HMDs
Abstract:To address the Navy need for an integrated day/night helmet-mounted display (HMD) system that delivers symbology during brownout conditions, Physical Optics Corporation (POC) proposes to develop a new Holographic Brownout Condition Adaptive Symbology (HOBCAS) system for day/night HMDs. This proposed system is based on a unique combination of narrow-band 3-color (RGB) high see-through holographic optics, OLED microdisplays, and symbology imagery display. The innovations in HOBCAS will enable the system to adapt to ambient conditions and allow for a quick clip-on to HMD and night vision goggles (NVGs) with independently controllable symbology imagery and functionality using existing helmet mounts. In Phase I, POC will demonstrate the feasibility of HOBCAS system by designing a breadboard prototype that illustrates see-through, holographic beam combination, and symbol rendering capabilities. HOBCAS system meets the needs of the Navy by providing high-resolution (>800x600) symbology with high luminance (>400 cd/m^2) and color capability. POC will also develop a mechanical means for a clip-on solution to switching from day to night HMDs. In Phase II, POC plans to develop a mature prototype that will allow a pilot to test the system's capabilities and evaluate the symbology.

Title:Eyesafer Fiber Laser Technology for Shipboard Defense
Abstract:This proposal is for the development of a new all fiber single mode Tm3+-doped two micron fiber laser with output power of 5 Kilowatts. This new fiber laser is retina safe, reducing the possibility of eye damage to the operators due to scattering and reflections. The laser wavelength is located in one of atmospheric transmission windows as well. This type of fiber laser can be used in the Navy’s directed energy system for active defense. The lasers can provide an effective “Sea shield” against adversary ballistic or cruise missile attacks, and enable safer operation in the littoral environment. Research will be conducted to study the ultimate limit of continuous wave power for single-fiber, diffraction-limited eyesafe sources. Large core fibers with high order mode suppression will be designed and fabricated for both laser and amplifier fibers. Glass with optimized Tm2O3 doping concentration will be chosen to generate highly efficient laser output. A Master Oscillator Power Amplifier (MOPA) system will be designed to generate 5 KW two micron laser with wavelength control. Spectrum combining can be used for further power scaling up to 10s of KW level.

Title:Eyesafer Fiber Laser Technology for Shipboard Defense
Abstract:Q-Peak has recently developed “eyesafer” high-power, efficient, thulium (Tm)-doped, 2050-nm-wavelength silica fiber (Tm:fiber) lasers that have the potential to scale up to the power levels needed for shipboard defense. The longer wavelength cannot pass through to the retina and hence presents a greatly reduced eye hazard. Requirements for laser beam quality depend on the nature of the threat, but the most challenging threats demand near-diffraction-limited beams. In the work proposed here, we will investigate the fundamental limits to power, with diffraction-limited beam quality, from a single Tm:fiber laser. This will determine the system design architecture for high-power directed-energy systems, particularly how many individual fiber lasers are needed for coherent beam- combined systems.

Title:Micro-optics Lens Array-Based Eyepiece and Objective Lens
Abstract:In response to Navy Naval Special Warfare Visual Augmentation Systems (VAS) Program needs for developing and prototyping microlens array (MLA) optical components such as eyepiece lenses with wide field of view to be used in Night Vision Goggles (NVGs), Physical Optics Corporation (POC) proposes to develop a new Micro Optics Lens Array- based eyepiece and objective lens (MOLA) for NVG with increased field of view (>40 deg) based on a unique combination of coaxially and concentrically arranged MLA to achieve compact form factor and with the eye box size of up to 40 mm. In addition, POC's innovative MLA self-aligned assembly technique by molding, requiring high-precision alignment of these components, can be easily achieved. In Phase I, POC will develop a design of MOLA and prove the feasibility of the proposed approach by demonstrating prototypes of an optical component using commercial-off-the-shelf MLA technology and analyses of performance in comparison to conventional bulk optics for NVGs. In Phase II, POC will finalize the design, development, and evaluation of MOLA prototypes for a traditional NVG device and develop and evaluate a MOLA eyepiece components for a wide horizontal field of view (>80 deg) NVG.

Title:Wide Angle Lens Array Night Vision Optics
Abstract:The Naval Special Warfare Visual Augmentation Systems program has an interest in developing an 80 degree field of view (FOV) aviator night vision system (ANVIS) to more closely match the panoramic viewing capability of the unaided human eye. Standard ANVIS and night vision goggles, which are based on conventional optics, have only a 40° degree FOV. Increasing the FOV using conventional optical techniques would result in large, heavy systems that can cause neck strain in pilots. The Spectral Imaging Laboratory (SPILAB) proposes the development of curved lens array optics as a means of increasing the FOV while decreasing size, weight, and cost. The new lens array optics would have the additional advantage of an infinite depth of field. This could benefit pilots by enabling them to read nearby instrument panels through the optical system without the need to adjust focus when viewing outside the cockpit window.

Title:Wide FOV Foveal Night Vision System
Abstract:In this SBIR proposal, Kent Optronics, Inc. (KOI) proposes to develop a novel foveal night vision system (F-NVS) with wide field-of-view (FOV) for military activities in night and/or low-light-level environments. The critical element is the wide FOV objective subsystem with a passive wavefront compensator for achromatic and polarization insensitive wavefront compensation. The passive wavefront compensator is made special solid- state polymer material in multilayered film format with unique spatial patterns. The resulted F-NVS is compact, lightweight and low cost. Our preliminary design results via model simulation have proven that the F-NVS possesses the foveated imaging feature with the wide FOV to 90o (±45o) and the high resolution >1.6 cycles/mrad. In Phase I, the objective and eyepiece subsystems will be designed. The concept of the foveal NVS will be demonstrated from a demo device through more detailed simulation on the system and the design of the passive wavefront compensator that is included in the system. The Phase I Option will start to develop such a wavefront compensator for the breadboard level demonstration of the F-NVS. Phase II and Phase III will develop and test the prototype of the wide FOV foveal NVS, followed by the product commercialization.

Title:Foveal Imaging Night Vision System
Abstract:Warfighters operating in a night environment are always in search of more situation awareness. For decades, this situation awareness (SA) has been provided at night via monocular (PVS/7 or PVS/14) night vision goggles or binocular (ANVIS) goggles. Although these systems have served our soldiers well with their 40 degree fields of view, warfighters always ask for more field of view for better situation awareness. A number of systems have been fielded which have larger fields of view, but they all require multiple image intensifier tubes and none of these systems are slated for production. SA Photonics has developed the preliminary design for a 80 degree foveated night vision system. By developing a foveated design, one which rolls off resolution and luminance from the center of the field of view to the edge, we ensure that the system will meet the required needs of the warfighter in a package which is neither too heavy nor too large. We feel that the combination of our very promising design, coupled with our expert consultants and our extremely strong record of commercialization will allow NSWC-Crane to field a wide field of view night vision system with tremendous advantages.

Title:Affordable High Yield Photocathodes for FEL Injectors
Abstract:For FEL based systems to become practical as weapons, it is necessary photoinjectors be used to generate the low emittance, high current, high peak charge electrons needed for photon production. Higher overall system reliability can be achieved if the photoemitter operates in the visible wavelength range. Photocathodes are consumables in the operation of an FEL injector gun and are required to be made as reliable, inexpensive and simple to use as possible. Amorphous silicon germanium shows great promise as a negative electron affinity visible wavelength photocathode suitable for FEL gun systems. Advantages of amorphous silicon germanium include a high degree of immunity to charged particle flux, low thermal emittance, bandgap tunability and low production cost. Amorphous silicon germanium can be readily grown on a variety of substrates including those transparent at its bandgap enabling transmission mode as well as reflection mode photocathodes to be fabricated.

Title:Processing Signals In High Density Electromagnetic Environments
Abstract:Legacy approaches to Radar Threat Warning such as SLQ-32 are being completely replaced through modernization programs such as SEWIP Block 2, which will likely replace IFM technology with a channelized receiver approach. In doing this, the benefits of COTS hardware modules can be leveraged, along with the associated Modular Open Systems Architecture (MOSA) concepts. However, the COTS RF receiver modules at the front end and subsequent A/D converters become the vulnerable point in the system, and are susceptible to being saturated by other onboard RF transmissions. In this effort, Azure will develop and validate advanced cancellation algorithms that will extend the usable dynamic range of the receiver front ends, preserving weak threat signals in the presence of powerful onboard interference.

Title:Processing Signals In High Density Electromagnetic Environments
Abstract:Signal detection and measurement of signals of interest in the presence of high power in- band emissions from own-ship emitters using a multi-pronged system approach is proposed versus using one single technique. Due to the large signal levels of on-board emitters and resulting large dynamic range under which low-level signals must be detected while maintaining spectral coverage, RAS proposes a suite of techniques starting with the Electronic Support system front-end to mitigate RF component saturation through the customized signal detection and processing paths. Adaptive signal suppression is incorporated with RF selectable filtering, attenuation, and/or limiting. Signal processing techniques include time-frequency excision of large signals, pulse interference detection and characterization and ICA. Existing RAS FPGA designs and expertise for real-time parameter measurements, advanced techniques for characterizing intentional modulation on pulse, precision parameter measurement, Fourier transforms, and Wigner-Ville / Hough processing will be leveraged. Automatic resource management and knowledge and use of own-ship radar transmission parameters and timing will be included based on SEWIP Block 2 architectures. Requirements and the system architecture will be developed and algorithms characterized using a MATLABTM model. The hardware feasibility study will establish a baseline for Phase II development in open architecture COTS hardware.

Title:LUCID: Limiting Uncertainty in Command Information Displays
Abstract:Modern military systems employ a variety of models to realistically represent warfighting capabilities and the environment in which these capabilities operate. However, these models rarely represent the uncertainty inherent in real-world domains. Further, the systems rarely visualize uncertainty in decision-makers’ command displays. This proposal outlines a research and development program to identify and remedy deficiencies in the portrayal of uncertainty in military decision support systems. Aptima working with its partner, Lockheed Martin, will modify and expand Aptima’s MUSE (Modeling Uncertainty in Shifting Environments) model for Aegis command displays and design visualization techniques for representing individual information reliability and the aggregate uncertainty to the decision maker in an intuitive manner. Further we will conduct assessments of the model and the visualization techniques. LUCID (Limiting Uncertainty in Command Information Displays) will provide the commander of Navy ships greater situational awareness for making decisions.

Title:Tools to Support Understanding of Information Uncertainty in Combat Operations
Abstract:Sonalysts proposes to investigate the field of research associated with uncertainty visualization and utilize this information in conjunction with human systems integration (HSI) design principles and subject matter expertise (SME) to design innovative uncertainty visualization approaches and methods for validating overall approach effectiveness. One of the biggest challenges for today’s war-fighter is the task of making important tactical decisions under stressful conditions based on a potentially large volume of information that has varying levels of uncertainty. In order to accurately interpret uncertain data from various sources effectively, it is important that the decision maker has an adequate understanding of the level of uncertainty associated with any particular data. This requires the employment of a visualization approach that conveys uncertainty in a way that allows the decision maker to associate the appropriate level of confidence in any given data. Sonalysts proposes to leverage its extensive experience with HSI to develop innovative uncertainty visualizations along with metrics and usability tests to quantify the overall effectiveness of new and existing uncertainty visualization strategies. The ability to effectively convey the level of uncertainty associated with tactical data increases the war-fighter’s ability to correctly make critical tactical decisions that achieve mission objectives and saves lives.

Title:WDM Based True Time Delay Array for Advanced RF Beamforming
Abstract:An innovative concept for a scalable true time delay (TTD) array for digital beamforming is proposed. The concept is photonics and fiber optic wavelength division multiplexing (WDM) based and will support transmit/receive applications over the 1 to 20 GHz, extendable up to V bands. The design provides a digitally controlled true time delay array for beamforming effectively adaptive to Navy phased array radars and RF communications in any portion of RF spectral coverage. The Phase I approach will develop the photonic WDM true time delay array and demonstrate the key characteristics followed by a Phase II Program that will optimize the design and demonstrate full functioning 2x4 or 4x4 array of TTD for beamforming. Agiltron is working closely with BAE Systems on this unconventional approach leveraging our recent breakthroughs in manufacturing high performance fiber delay lines and fiber optic WDM technologies. The proposed approach overcomes the deficiencies associated with electronic beam forming components, offering frequency independent performance by controlling the phase and amplitude in a small, lightweight package with minimal power consumption. Our approach provides unprecedented performance in terms of scalability to large array, wide dynamic range, and fast dynamic reconfigurability.

Title:Improved Contact Association
Abstract:The US Navy is developing an Undersea Warfare Decision Support System (USW-DSS), the purpose of which is to provide a net-centric capability to support fleet commanders. A significant advantage the architecture will provide is the integration of the C4I domain and the combat systems. Since many different types of sensors will be integrated, a fundamental need is a robust mechanism for the association and fusion the multi-sensor data and for generating a Common Operational Picture (COP). Classical approaches to association only use kinematic data, and feature data, measured by the individual sensors, may be used to augment the kinematic data to assist in the association problem. The objective of this program is to develop a feature/classification-aided track association algorithm that is compatible with the following: (i) the non-commensurate track and feature data that is common for the sensors expected in the USW-DSS architecture; (ii) the requirements for implementing the COP architecture; (iii) the requirements for implementing multi-hypothesis tracking. The solution will be evaluated using an extensive multi-sensor simulation suite, and a variety of metrics will be applied to assess tracking the communication link load performance.

Title:High Power Density, High Efficiency, Fast Transient Response Silicon Carbide (SiC)-Based Power Supplies For the Next- Generation of Radars
Abstract:Advances in radar systems are pushing the limits of present radar power supply technology. To enable new concepts, such as active array radar systems, significant improvements (i.e., power densities >200 W/in3, efficiency > 90%, transient response < 10 µs, etc.) in radar power supply technology is required. To achieve these goals, the volume of present state-of-the-art silicon-based power electronics systems must be cut in half, while maintaining (and in most cases improving) the efficiency of those systems. Such high power density systems will face tremendous thermal challenges since more power per unit of volume under similar efficiency requirements and electronics packaging technology means higher temperature rise. Present high power density Si-based systems are severely limited by the thermal performance of active and passive components as well as electronics packaging technology, and therefore, the achievement of the target radar power supply goals cannot be attained without a revolutionary change in radar power supply technology. This Small Business Innovation Research Phase I project seeks to develop highly efficient (>94%) and compact (>250 W/in3) next-generation radar power supplies utilizing the now emerging silicon-carbide (SiC) power devices.

Title:RADAR POWER SOURCES AND POWER CONDITIONING
Abstract:Power supplies for future Navy active phased array radar systems require significantly advanced technologies to provide higher power density, faster transient response, lower output capacitance, and lower cost and noise than present commercial technologies. The technical challenges include thickness reduction to less than 10mm, conversion efficiency greater than 90%, and thermal control at base plate temperature 70°C. Custom Manufacturing & Engineering (CME) proposes to design and develop an isolated DC/DC converter for pulsed current loads of 300V input / 28V output, output power greater than 1kW and power density higher than 200W/in3 with response time and settling time each within 10ms, and overshoot less than 4%. To reach these goals, CME will identify new and innovative research and development approaches by theoretical analysis, computer simulations, and sample testing of currently available commercial off-the-shelf (COTS) components that will lead to an effective modified COTS design. CME has a long history and extensive experience in pursuing power supply advance technologies with Navy applications. The company’s design experience includes rugged military power supplies, innovative switching topology, and a digital control loop design that are adaptable for this project.

Title:Innovative Power Amplifier Gate Thermal Management for Active Radar Systems
Abstract:This Phase-I SBIR MDA Proposal proposes the use of a new class of diamond-seeded solid-state material system for the manufacture of virtually all heat-generating solid-state electronics in X-band and Ballistic Missile Defense radar components and systems. In this proposal wherein much preliminary (MDA-funded) work has been demonstrated hitherto by the authors, Gallium Nitride-on-SiC power amplifiers in X-band radar are replaced with GaN-on-Diamond power amplifiers to enable nearly total and immediate heat extraction from the device’s active region. This proposal is specifically focused on exfoliating GaN FET epitaxy from SiC (rather than Si), and attaching the GaN FET to a CVD Diamond substrate. Free-standing polycrystalline CVD diamond – nature’s most efficient thermal conductor – enables nearly perfect heat extraction from a “hot” device, owing to the extreme thermal conductivity of diamond (GaAs, Si, and SiC are 35W/m/K, 150W/m/K and 390W/m/K respectively; diamond ranges from 1200-2000 W/m/K depending on quality). In the proposed scheme, 5+ W/mm of output RF power are expected to be measured from the GaN FET-on-Diamond device while operating at half the temperature of GaN-on-SiC devices. The semiconductor-on-diamond technology proposed here may be applied to Si, GaAs, GaN, SiC, SiGe, etc. at up to 8” in wafer diameter.

Title:GaN on Diamond HEMT for Gate Thermal Management
Abstract:GaN based HEMTs are capable of achieving high power density at high frequency. Thus, solid-state high power amplifiers based on GaN will be smaller and lighter than incumbent technologies. The use of a silicon substrate for GaN HEMTs provides a reliable GaN device which is also economical. Discrete devices and MMICs based on GaN on Si are ideally suited for applications in high power radar modules for electronically scanned arrays (ESAs). The performance and reliability of GaN HEMTs is closely linked to the operating temperature. For this program, we will further develop a novel GaN on diamond HEMT structure with superior thermal conductivity relative to conventional approaches. In addition to significantly improving the thermal resistance, we will develop a novel process pathway that will be inherently manufacturable and cost effective thus enabling the maximum utilization of GaN technology in various military applications. In Phase I, we will demonstrate key features of the material structure and thermal modeling of the concept device design. In Phase II, we will advance the maturity of the concept through optimization of the process and demonstrating a functional GaN on diamond HEMT device tailored for ESA to evaluate the thermal and electrical performance.

Title:Reliable Acoustic Path Vertical Line Array
Abstract:The U.S. Navy has researched the use of various acoustic sensing technologies that exploit the deep water reliable acoustic path (RAP) using vertical line arrays (VLA’s) of vector sensors with success. The buoys used were, however, large, over-the–side deployed, research systems to demonstrate the approach. What is desired is a viable approach that is smaller and can be ideally packaged to facilitate ease of handling for Naval crewmen. Phase I will perform analytical modeling studies of the required system and subsystem components to determine the suitability for RAP VLA operation and do some sensor proof-of-concept evaluations to supplement the modeling. The objective is to establish a cost effective, easily deployable, RAP sensor system that can be prototyped and demonstrated in Phase II. Component level technologies to be evaluated include miniature low noise vector sensors, array electronics and telemetry, DC power generation and distribution, and acoustic communications between the array and a surface platform. System level technologies include end-to-end array design, conventional and advanced signal processing techniques suitable for a deep water vector sensor line array, packaging and deployment concepts, and communication modalities.

Abstract:Inefficiencies in radar transmitters lead to issues with power generation, heat removal, reduced lifetime, and cost of operation. A high power RF amplifier with high efficiency would be very useful in military and commercial applications. Auriga is proposing to investigate two methods for improving the efficiency of S and X-band amplifiers. Gallium Nitride (GaN) devices will be used to satisfy the high power requirement. Its use in high efficiency technologies has been demonstrated by Auriga.

Title:High-Efficiency GaN HEMT SSPAs for S-band Radar
Abstract:S and X-band radars are central to the Air and Missile defense capability of the US ballistic missile defense (BMD) systems. The objective of this Phase I program is to investigate various PA classes of operation and identify approaches with significantly improved efficiency. The strategy proposed in this SBIR Phase I proposal is to combine the benefits of high efficiency switching architectures with the power and bandwidth capability offered by GaN HEMTs. High efficiencies are possible through use of PA classes such as D, E or F that operate the transistor as a switch. Such approaches offer significant promise for high efficiency RF transmitters provided fundamental efforts are expended to overcome the technical challenges in the input and output matching designs posed in such approaches.

Title:Wireless Automated Service Oriented Architecture Capable Traffic Manager
Abstract:The Navy seeks to support development of an automated intelligent network traffic management algorithms and implementations to support OA/SOA network communications over constrained communications channels. Broadata Communications, Inc. (BCI) proposes to develop a new Wireless Automated Service Oriented Architecture Capable Traffic Manager (STM) based on its innovations in incorporating new network measurement technology in middle-box QoS network management. It focuses on providing two imperative features: the automated management of network resources without reconfiguration and the effective utilization and prioritization of Navy services over a network that includes wireless long propagation links. The intelligence of our solution is based on an innovative, network independent and humanly intuitive measurement of available bandwidth, automated bottleneck link bandwidth estimation, traffic differentiation, and traffic forecasting. We propose to put those unique abilities for achieving superior performance for the Navy problem at hand.

Title:Intelligent Network Traffic Management
Abstract:We offer to research, design and prototype portions of an intelligent messaging framework that provides a layered approach to the problem, and leverages and integrates with commercial SOA ESB technologies. The first layer applies content filtering on the producer or consumer side based on network conditions, filter probability and message distribution. The second layer provides state filtering which determines whether the content has changed enough from the last transmission based on consumer constraints. The third layer uses a commercial product, DDS, to apply history, prioritization and queuing QoS. The fourth layer applies transactional filtering which removes elements that have not changed from the last transaction. The fifth layer applies binary compression using the Efficient XML emerging standard. The fifth layer applies network topology aware routing, leveraging MANET developing techniques. In summary, messages are sent based on consumer content and state constraints, reliably delivered using DDS QoS, reduced in size by only sending what changed and compressing the message, and uses knowledge of the network topology to reduce redundant messaging across the same connection. The framework approach is to use JBoss, an Open Source ESB to manage the rules at each layer and the workflow.

Title:Interoperability and compatibility techniques for Counter Radio controlled IED Electronic Warfare (CREW) and other Radio Frequency Communication
Abstract:The simultaneous need for blue force broadband communications link and the proliferation of sensitive SIGINT receivers has created the need for the US Navy to develop a system capable of suppressing broadband interference in close proximity to sensitive receivers. The goal of the current SBIR is to develop a low cost system that will provide the US Navy with the capability to deploy and use a variety of transmitters, communication systems, and SIGINT systems in close proximity without the requirement of connecting the various systems. A wideband interference rejecting antenna system must provide broadband omni-directional coverage when installed on a vehicle and be capable of maximum wideband interference cancellation. The system must operate over a minimum frequency range of today’s existing terrestrial SIGINT and communications systems. Finally, the system must be capable of rejecting both on-vehicle and in-convoy interference sources. The FIRST RF team proposes a new system that combines broadband antenna technology and advanced null forming techniques with state of the art cancellation electronics to provide a wideband wireless cancellation technology to meet the US Navy requirements.

Title:Wideband Conformal Antenna
Abstract:As Joint Counter Radio Frequency IED Electronic Warfare (JCREW) technology becomes increasingly prolific in military applications for ground forces, there is a corresponding requirement to develop antenna systems that accommodate present and foreseeable integration and performance challenges for these systems. While existing antenna systems for JCREW applications have demonstrated the ability to provide acceptable performance on a wide variety of ground mobile platforms, each of these platforms has different impacts on – and experiences effects due to – the desired performance of these systems. In order to achieve more uniform performance and seamless integration for future JCREW systems, the focus of this effort is on conformal vehicle-mounted antennas, as they present the most significant technical challenges to meeting these goals. To overcome these challenges, technological advances must be made to develop antenna hardware that can be readily integrated onto a wide variety of platforms without compromising EW performance or the performance of existing systems. A natural approach to simultaneously addressing these problems is to use conformally-mounted antennas. Specifically, if antennas tailored to JCREW requirements can be mounted on the broad outward-facing surfaces common to military ground vehicles, they will provide techniques for addressing both electrical and mechanical challenges experienced in current systems.

Title:Development of Wideband Conformal IED Jammer Antenna
Abstract:Improvised explosive devices (IEDs) have become a common part of the arsenal used by the enemy against US forces. Current military vehicles use a monopole or whip antenna to radiate jamming signals to mitigate these threats. These antennas have a high profile, which can extend from 2.5 ft to over 5 ft in height, and are easily visible and prone to being damaged or destroyed while on patrol. New technology is needed to reduce the profile of these antennas while maintaining or possibly increasing the operations effectiveness. To address this critical military need, Luna Innovations will leverage its cross disciplinary knowledge in electromagnetics and materials engineering to design a compact broadband antenna capable of omni-directional coverage in azimuth while maintaining a low profile. Luna’s proposed approach features a traditional antenna design and specially engineered materials as the antenna substrate which enables antenna size miniaturization and prevents shorting of the antenna near a metal surface.

Title:Non-Lethal Swimmer Deterrent
Abstract:A non-lethal but effective electrical swimmer barrier is proposed that will take advantage of ocean oil-barrier deployment technology, the conductive properties of near-coast waters, and the physiological sensitivities of human swimmers to electrical shocks. Experimental validation will be made of the use of intermittent, spatially-distributed burst- mode current pulses of short duration to create enhanced deterrence without incurring added risk of lethality. A novel secondary-electrode pulse current distribution system will localize the swimmer interdiction areas and provide the desired effect-free regions close to ships and piers. Feedback control of the deployable power supplies will be used to compensate for temperature changes, variations in salinity, water pollution, ship proximity, and configuration of the area to be protected. To energize the system, either shore or ship’s power can be used; power demand is estimated to be 50 Watts per meter of coverage. The entire electrode set and its power supply will be readily deployable and retrievable by two persons working from a 24- to 28-foot boat. Electrode corrosion will be prevented by electrochemical techniques already proven in DTI’s pulsed-electric-field (PEF) sewage-treatment and food-processing equipment.

Title:Non-Lethal Electrical Swimmer Deterrent System
Abstract:To address the Navy’s need for a nonlethal swimmer deterrent system, Physical Optics Corporation (POC) proposes to develop a new Nonlethal Electrical Swimmer Deterrent (NESD) system. This system is based on an innovative system architect and novel electrode configuration that offers capability to generate electric field of 2 volts/ft within its operating region and delivers a nonlethal shock to the intruder, thereby preventing trespassing or sabotage. The compact, man-portable system can be easily deployed by two personnel on a 24–28 ft boat. The system design introduces electric field gradually to deter marine life thereby avoiding shock, which will facilitate public acceptance of this system and address concerns of wildlife organizations. In addition to this, the NESD design is modular, adaptable, and scalable, allowing multiple electrodes to be attached on to a single electrical controller unit. In Phase I POC will demonstrate the feasibility of NESD system by developing a bench-top, proof-of-concept device with a technology readiness level (TRL) of 3 or greater. In Phase II, we will demonstrate a protective electrical barrier generator for naval security with a TRL 6 or greater.

Title:Autonomous Watercraft Docking and Refueling Architecture (AWDRA)
Abstract:With the increased emphasis in recent years on expanding the Navy’s capabilities in littoral battlespace, there has been an increasing demand for self-sustaining autonomous vehicle networks that can support this expansion. Manned refueling and servicing of surface vehicles is currently possible, but imposes a significant degree of risk on the crew; bringing the autonomous vehicles back to a host ship for refueling and replenishment takes time and effort away from the assigned mission. Michigan Aerospace Corporation proposes to leverage its extensive technical experience in the field of autonomous servicing systems to develop a common, robust, multi-platform- capable refueling system architecture. The Autonomous Watercraft Docking and Refueling Architecture (AWDRA) will provide for a compliant capture system that is used in a bow-to-stern rendezvous and docking operation between an automated surface tender and a target surface vehicle in need of replenishment while both vehicles are moving forward in up to Sea State 3 conditions.

Title:Offboard Refueling Support System for Unmanned Surface Vehicles
Abstract:It is proposed that a new “refueling mission package” capability be developed for the LCS ASW Unmanned Surface Vehicle (USV) to perform function of a refueling tanker for refueling other offboard systems (USVs or unmanned underwater vehicles) without restricting host ship operations. Utilizing the existing ASW USV “hard point” deck sockets and command and control, this refueling mission package will minimize impact on LCS by eliminating the need for another unique USV. The refueling USV objective will be to transit to the watercraft, connect a refueling hose to a common port on the watercraft, refuel the watercraft, detach the refueling hose, and return to the host ship without human intervention. We will leverage Oceaneering's Large Vessel Interface Lift-on/Lift-off Crane (LVI Lo/Lo) Program to develop the motion sensing and compensation refueling effector. We propose to demonstrate concept feasibility by integrating Navatek developed USV-to- USV motion simulations with Oceaneering's LVI Li/Lo Land Based Test Facility.

Title:Monitoring of Arcing Condition in GMAW and Its Variants
Abstract:This SBIR Phase I project is to prove the feasibility of an innovative weld monitoring technology. This innovative technology is characterized by (1) an innovative non- transferred arc sensor which responds to both surface conductivity and sensor-to-joint distance and can be used to monitor the joint geometry and possible surface contamination such as paint, oil, sand, etc. and (2) an innovative mechanism for determining the location of the arc root in relation to the joint geometry based on arc current and voltage waveforms. While the joint geometry and surface condition are the major variables whose deviations affect the arcing condition, the arc root location and arc current can be considered the results of their effects. The proposed monitoring method thus simultaneously monitors both the causes and results of possible arcing condition deviations.

Abstract:In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma emission lines to enhance the system sensitivity, and d) the development and application of a Continuous Wavelet Transform (CWT) based peak detection algorithm to enhance the sensor sensitivity, and to reveal plasma emission signatures associated with contaminations. With these innovations, we expect that the final product of this proposal will be a compact (~4x4x2 inches), light weight (~1lb), low cost (<$1K/ unit if produced in small volume), and wearable sensor.

Title:Robust Deployable Superstructure Enclosure System
Abstract:The U.S. shipbuilding industry has fallen behind the global industry in terms of meeting “World Class” commercial best manufacturing practices. The U.S. shipbuilding industry desires to recover our status as a world leader in this area. One step along the path of upgrading our infrastructure to world class manufacturing quality and standards is to utilize enclosure systems during ship maintenance and surface preparation and coatings work. Currently this type of work is often performed in an open air environment which, decreases productivity, reduces efficiency and allows release of regulated air emissions into the environment. An enclosure system that is easy to use, easy to relocated from one work location to the next, easily maintained, storable within a small cube, and robust is desired. Finally, it is desirable that these structures are able to function on a ship’s superstructures and around complicated geometries. Enclosures of this type will increase productivity, by decreasing down time (allowing work to continue during inclement weather), allow capture of regulated air emissions (VOC’s), and ultimately increase worker efficiency, comfort, and safety. Federal Fabrics-Fibers (FFF) proposes an AirBeam Supported Enclosure System (ABSES) solution. This enclosure will be supported using our AirBeam and AirFrame technology. FFF has considerable experience in designing and manufacturing custom AirBeam supported shelters, i.e. tents and enclosures. Due to the nature of the AirBeam and AirFrame technology this system lends itself to easily be adapted to different configurations and sizes. For example FFF has produced “enclosures” ranging from 15 ft spans × 15 ft long to 30ft spans by potentially unlimited lengths. In addition, AirBeams with spans of over 80 ft have been produced here at FFF and adding a skin to make a relatively large enclosure is a simple task.

Title:Tough Reconfigurable Topside Shipbuilding Manufacturing Structure
Abstract:Military and emergency civilian shelters are typically designed for mobile operations with relatively short set-up/strike cycles. Durability with minimal maintenance and logistical support are then essential. These characteristics also hold true for shipyard construction and environmental structures. However unlike military and civilian structures, topside shipyard structures must withstand grinding, hot work and day to day use in a manufacturing environment. In addition ship topside structures vary in geometric complexity, material and accessibility. The shelter system must also be designed to withstand high winds, ice and snow loads. KaZaK’s Phase I efforts will work with shipyards to define shelter requirements, then further refine/develop proposed innovations through analysis and scaled prototype models, while refining designs and full scale testing during Phase II. KaZaK will investigate a novel composite material construction in combination with a highly automated panel production process that has been used with great success in other structural design problems that required a balance between deployed stiffness, durability and low cost. Full scale Navy/shipyard prototype fabrication/assembly and shelter testing is anticipated by the end of Phase II.

Title:Rapid Low Cost Application of Adhesive Tangs for Support of Shipboard Fire Protection Materials
Abstract:The next generation of U.S. Navy combatants is currently under design with topside structures considering composite materials. Composite topside structures will reduce weight, provide significantly reduced RCS signatures and assist the Navy to meet performance goals. Development of Navy topside structures has evolved based on prior experience which has included the design and construction of the AMES Mast, Forward Director Room (first article) and more recently the extensive research and development to qualify the design of the DDG Composite Helicopter Hangar. Several current composite programs, the design and manufacture of the DDG 1000 topside structure and NSRP’s Improved Affordability for Composite Structure are working to reduce cost, weight and manufacturing complexity. An adhesive tang system that supports shipboard passive fire protection is another step to outfitting a composite topside structure. KaZaK’s Phase I efforts will work with a shipyard to define system requirements, further refine/develop its proposed innovations through analysis and fire, smoke and toxicity testing (FST), while refining designs and laboratory qualification testing during Phase II. KaZaK will investigate a novel material construction that has been used with great success in other design problems that required a balance between FST requirements, adhesion and structural support at low cost.

Title:Adhesives for Rapid Outfitting and Insulation Attachment
Abstract:There is an ongoing requirement to reduce the cost and time associated with insulation attachment during outfitting and new construction on naval vessels. Currently, the primary method of attaching insulation on metal surfaces is through the used of welded studs. These studs are attached to decks and bulkheads early in the construction process and are often damaged before the construction process is complete. Any changes or additions late in the construction process require additional “hot-work” which can be expensive to arrange and may damage existing finishes. In addition, welded studs are not an acceptable method for attachment on composite bulkheads. The objective of this proposal is to utilize the epoxy/urethane/acrylate hybrid resins that have been commercialized by Triangle Polymer Technologies to develop a strong, safe, fast curing adhesive material that has the physical and mechanical properties conducive to operation above 300F and under extreme conditions can be easily used in confined shipboard spaces. Our novel hybrid resins have proven adhesion to a wide variety of surfaces and the set time can be altered from under 1 minute to over 1 hour without a change in performance properties. This will produce a dramatic increase in operational effectiveness of all military operations.

In this SBIR, DTI proposes to apply and extend its power supply and switching technologies to develop high voltage / high power converters that will meet the requirements of this SBIR, using combinations of power converter modules based on commercially available devices to accommodate input prime power at 4160 to 13.8 kV AC or 6 kV DC at multi-MW power levels. Under this SBIR effort, DTI proposes to analyze several candidate architectures to achieve this goal, and characterize one or more of these architectures. Approaches to maximize power conversion efficiency while minimizing weight and volume will be investigated. In Phase I, DTI will investigate various architectures to achieve the power conversion goals of this topic, and provide analytical and experimental data to support further architectural optimization.

Title:High Efficiency and High Power Quality Electrical Power Conversion
Abstract:The proposed shipboard medium voltage AC to DC converter system will allow for various input and output levels based on a power dense, efficient, low cost, high quality output, and modular design expandable up to 6MW. A 450kW power conversion module uses advanced power switching devices and a uniquely designed isolation transformer. The 13.8kV module front-end is connected across a series cascade of H-Bridges that are switched at a low frequency to reduce losses, synthesize a high quality sine wave, operate at unity power factor, and meet low current distortion per MIL-STD-1399-680. Each DC output of the H-Bridge section acts as an input for a Series Loaded Resonant DC/DC converter that includes high frequency transformer isolation. The SLR converter uses Super Gate Turn Off devices from Silicon Power Corporation operating at a high frequency to minimize the transformer. Low output DC ripple is realized by full wave rectifying and interleaving each SLR output to form a single DC output. Multiple paralleled modules combine to achieve a ripple voltage of 0.1% rated up to 6MW. Each module output is regulated to handle transient load conditions and can be adjusted between 800- to-1000V as influenced by the transformer turns ration.

Title:Distributed Sensor Network for Autonomous Hull Monitoring
Abstract:Maintenance of naval ship hulls is important for a number of reasons. The current techniques of hull husbandry, the periodic inspection of the hulls and taking corrective actions, is a very time consuming and labor intensive process. In order to simplify planning for such a task and to reduce uncertainties during the drydock periods, PSI is offering a solution that is based on a sensor network mounted inside the hull of the ships. The sensors will be able to collect information on various hull conditions. The information will be stored in a database for detecting anomalies and will draw the attention of an operator to areas where a detailed look is warranted. The advantages include improvement in the quality of the ship hull inspections, reduction in personnel time and reduced life cycle costs for the new Littoral Combat Ships.

Title:Autonomous Hull Inspection
Abstract:This proposal meets the goals of the solicitation topic NAVY 08-182 through the leveraging of technology already developed with funding from the ONR and direction of the NAVSEA Carderock Division Naval Surface Warfare Center. Through the use of the existing HullBUG platform combined with third party sensor systems, a comprehensive autonomous inspection system may be developed in a relatively short period of time that is cost effective. The HullBUG vehicle is a small (<30kg) tethered or tetherless vehicle that crawls on the underwater surface of a ship. The vehicle stays attached to the ship using a patented non-contact negative pressure device and uses soft rubber tires that do not mar or scratch the hull coating. Ship hull inspection with the HullBUG and the sensor suite allows for the assessment of the hull structure, investigation into corrosion, determination of the level of biofouling and the discovery of objects or threats that may have been attached to the hull by hostile parties. The system proposed herein provides the platform and the sensing technologies for accomplishing inspections while at sea or while moored in port.

Title:Autonomous Hull Inspection
Abstract:Ships and submarines require periodic inspections of their hulls for two reasons: in order to detect and locate potential threats to the ship as well as the identification and quantification of a variety of factors relating to the material condition of the ship. These include the existence of threats such as limpet mines, and the condition and fitness for service of both the freeboard and underwater hull paint system, the presence of corrosion and the condition of the antifouling coatings, and the running gear of the ship (propellers, rudders, shafts, struts, suctions and anodes). Threat detection and neutralization is a primary function of keeping the Navy fleet safe and ready to serve, and the acquisition of maintenance related information will assist maintenance planners, port engineers and type commanders in executing maintenance at the required periodicity and at the lowest possible cost. Our eventual goal is to develop and demonstrate a prototype autonomous hull inspection system for both force protection and maintenance evaluation. The objective of Phase I is to demonstrate the feasibility of such a system. This will include generation of a concept of operations projecting the capabilities of the system, detailed technical descriptions of major components and subsystems, descriptions of interface requirements, and concept drawings.

Title:Automated System (H/W & S/W) Test and Repair Tool
Abstract:The growing complexity of distributed submarine combat systems has limited the Navy’s capability to test and repair software and hardware under a wide range of fault scenarios. As a result, the potential for mission failure due to system faults has risen to an unsatisfactory level. We propose to develop an Automated System Test and Repairer (A-STAR) to simplify the setup and execution of system tests and continually monitor the integrity of combat systems.A-STAR will run as a background process and detect software & hardware faults. A Performance Analysis & Measurement system (PAM) will visualize the real time data like a global Task Manager. The A-STAR program will generate a log identifying any detected problems. An automated trend analysis procedure will mine the event logs and compare attributes like fail states, operating time, processor usage, and others. The key innovations of A-STAR are its integrated monitoring and analysis environment and test scenario generation capability. A-STAR will allow the Non-SME to create a range of simple to complex test scenarios to evaluate the Navy system. A-STAR will then inject appropriate events to simulate system faults, provide real-time monitors of the system, and produce overall mission status reports.

Title:System for Automated Test and Integrity Verification (SAT-IV)
Abstract:In response to SBIR topic NAVY 08-184, Impact Technologies proposes to develop and demonstrate an automated monitoring system with the ability to detect, identifying, and repair performance problems within a widely distributed submarine combat system. The proposed non-invasive Prognostic and Health management (PHM) system, consisting of layered software applications and selectively chosen hardware signal interfaces, will be capable of identifying anomalous system behavior, interpreting the variety and location of the symptom’s cause, and automatically making necessary corrective actions when human input is not required. In this approach, real-time parametric system characterization will accumulate necessary features to facilitate a dynamic learning ability, thereby increasing prediction level confidence. An automated system detection tool will have the ability to integrate new system components into the prediction models, while automated monitoring tools provide the signals necessary to determine system health through a refined proprietary signal verification and validation application. Integrated logistics and maintenance support will allow even the most basically trained crew member to preserve expected system performance. In order to provide next generation submerged vessels the ability to perform their intended missions, these abilities are necessary to ensure peak system performance during combat scenarios.

Title:All Optical Tank Level Indicator System
Abstract:This Small Business Innovation Research Phase I project will combine optically-based measurements of pressure and the mature fiber optic networking technology used by the telecommunication and cable television industries to design and demonstrate an innovative All Optical Tank Level Indicator (TLI) System for VIRGINIA Class submarines and Navy fleet applications. Current TLI systems on submarines are expensive and time consuming to install and maintain due to their complicated design, large number of inventoried parts and their susceptibility to failure in the extreme and varied environments encountered within submarine tanks. PSI will evaluate two distinct optical pressure measurement techniques that may be coupled to a remotely located, ultra-sensitive, commercially available sensor control unit. The pressure measurements will be combined with tank engineering design data to determine the tank liquid level. One technique will be selected to for a distributed sensor system design that will be fabricated and tested during the Phase II program. The proposed innovative TLI system will be applicable to all tank sizes and geometries, reducing required part inventories and providing a robust, universal measurement solution. The proposed effort leverages PSI’s extensive and successful experience developing and delivering optically based sensor solutions for commercial and Navy Mil-Spec applications.

Title:Sensitive Passive Radio Frequency Identification (RFID) Tag Development
Abstract:Passive radio frequency identification (pRFID) transponders (tags) are relatively less expensive than active RFID (aRFID) tags, and the absence of a battery makes them attractive for applications where very long life is important. Passive tags derive their power from the RF field, and this power diversion significantly reduces the power received by the interrogator (reader), rendering this tag type the last choice when reader power is limited and the required range is large. In these cases, an alternative to a battery-powered tag that has mostly been confined to research environments is to power it with an external energy source such as light, magnetic fields, or acoustic energy. In the case of tagging ordnance, the acoustic and inductive powering are not attractive because the high amount of power required is unsafe. Light powered tags, on the other hand, have the potential to safely power the tag. Such a tag would contain, in addition to the circuitry and antenna, a solar cell to harness power from ambient light sources. This research program will examine the feasibility of this approach to making pRFID tags to be used for Naval ordnance.

Title:Sensitive Passive Radio Frequency Identification (RFID) Tag Development
Abstract:This is a Small Business innovation Research (SBIR) Phase I proposal to the Department of Defense (DoD) requests $100,000 support for Quintech Electronics and Communications, Inc. to demonstrate the feasibility of developing a Sensitive Passive Radio Frequency Identification (pRFID) tag that will meet the HERO requirement. This proposal responds to Navy topic number NAVY 08-186, “Sensitive Passive Radio Frequency Identification (RFID) Tag Development”. The significance of the HERO level tag being proposed here is that, the problem of tagging ordnances below deck on board a naval vessel will no longer be an issue of concern in terms of hazardous radiations. Because this tag will operated within the specified low power level, readers can be designed to radiate low power RF signal within the HERO specifications and still be able to read the tags. The innovation in this research is to create a switching effect that generates frequency to feed the input of an amplifier using energy harvested from HERO level radiation to power the logic circuit of the tag. Phase I activities will involve feasibility of using a proprietary switching device to create the alternating input to amplifier using ambient energy on board the vessel without external source.

Title:Cyanate Ester-based Pressure-sensitive Adhesive
Abstract:The aerospace industry needs an innovative pressure sensitive adhesive (PSA) to increase the performance of new aircraft paint-replacement coatings for both rotorcraft and fixed-winged platforms. The PSA will be used to adhere existing polymeric appliqué film materials to the current polyurethane-based aircraft body primers. Currently, existing PSAs cannot provide mechanical performance and solvent resistance in a broad temperature range while maintaining cost-effective processability and simple removal. The cyanate ester PSA offers many benefits over existing PSA systems, such as higher thermal stability and enhanced solvent resistance. The high tensile strength and modulus prevent weakening or fracture under stress and ensure adhesive failure upon removal without leaving residue. Once developed, the one-time use appliqué will be repositionable upon application and removable with minimal heat or tools involved. This PSA will use roll- to-roll web processing. This state-of-the-art PSA will transform the world of coatings for aircraft, broadening application areas, facilitating processing, and yielding higher quality mass production.

Title:Pressure Sensitive Adhesive (PSA) Development
Abstract:Applique films are under consideration as replacements for traditional paint based coating systems in newer military aircraft. Despite advantages in decreased corrosion, their practical use for this application has been hindered due to poor adhesion, particularly at extreme temperatures. To enable this promising technology, revolutionary developments in new pressure sensitive adhesive (PSA) systems must be accomplished to achieve excellent peel strength (2-8 lbs) at the temperatures to which the surface of the aircraft will be exposed (-55 to 140°C). Luna proposes a novel polymeric system based on our current developments that will surpass these requirements with excellent adhesion to a wide range of materials within this temperature range. This program will produce a new class of low volatile organic compound (VOC) adhesives that will demonstrate superior adhesion to polyurethane, nylon, polyimide, and fluoropolymer films, as well as to metal and composite substrates.

Title:Tacky, Polar Poly(organosiloxane) PSAs for Elegantly Tailored High Performance Adhesion
Abstract:NanoSonic would optimize our novel polyorganosiloxane and siloxane-urethane copolymers as high performance, residue free, pressure sensitive adhesives (PSAs) that would promote simple appliqué films repositioning/removal from NAVAIR rotorcraft and fixed-wing surfaces. The proposed PSAs offer excellent adhesion (50 – 250 N/m as a function of crosslink density per ASTM D 903 180° peel tests with adhesive failure, hence, residue free) over a temperature range of -120°C to > 350°C. While acrylic PSAs offer good adhesion, the proposed copolymers offered herein are synthetically engineered to provide service over a wider thermal range with enhanced solvent resistance (sea water, jet fuel and solvents) and weatherability against UV and ozone. During Phase I, accelerated ageing studies will be carried out to verify peel and lap shear adhesion of > 5psi up to 1,000 hours. Additional ageing studies shall be carried out under cryogenic and elevated temperatures (-65ºF to 285ºF) and after soaking metal-to-applique peel specimens in boiling water and heated solvents. NanoSonic currently offers specialty adhesives in volumes up to 55 gallon drums and shall work with our defense prime partner to increase the TRL from 5 - 8 of our cost effective, roll-to-roll compatible PSAs for appliqué films during Phase I and II.

Title:Pressure Sensitive Adhesive (PSA) Development
Abstract:In this Phase I, SciGenesis is adapting adhesive materials and techniques from our current adhesive projects to the development of a pressure sensitive adhesive that will meet rigorous NAVAIR requirements for military appliqué coatings. Our group has successfully incorporated stimuli-responsive characteristics to adhesive films, and when adapted to the proposed SBIR project will allow for the advanced performance high tack, peel, and shear strengths required for military applications, and facilitate easy removal when desired. The technical effort includes the synthesis, characterization, formulation, and testing of new PSA polymers. Materials are characterized using ASTM adhesive testing methods under aggressive environmental conditions designed to assess the thermal stability, chemical resistance, and shear strength of the samples. Successful polymer compositions must meet NAVAIR flight qualifications, and all testing equipment is available through the PIs research labs, the University of Southern Mississippi coatings labs and analytical services, or through collaborating commercial labs. SciGenesis will demonstrate the feasibility of incorporating an easy-release mechanism into preferred adhesive formulations, and characterize the rate of adhesive loss, release mechanism, and mode of adhesive failure. Adhesive formulations produced during this program will find immediate application as aircraft appliqué adhesive components and address other needs within the commercial aviation market.

Title:Pressure Sensitive Adhesive (PSA) Development
Abstract:The main thrust of the proposed research is to develop a new class of high-performance pressure-sensitive adhesives for use with aircraft appliqué films. Our approach merges the conventional pressure-sensitive adhesives technology with recent advances towards development of dry adhesives inspired by the nano-fibrillar structure of gecko- foot. Nano-texturing of pressure-sensitive adhesives is proposed here as a means of producing conformable surfaces which can establish thorough intermolecular contacts with rough substrates under pressure without requiring a liquid-type fluidity. The merger of the two (pressure-induced) adhesion mechanisms would complement the powerful and highly versatile contact mechanics of nano-fibrillar structures with the high adhesion energy and peel resistance of pressure-sensitive adhesives associated with their cavitation/fibrillation during debonding. The conformable nano-textured surfaces would remove a major constraint (the need for liquid-type fluidity) against optimum formulation and processing of pressure-sensitive adhesives with a desirable balance of peel and shear resistance, thermal and chemical stability, and repositionability and removability for use with aircraft applique films. The proposed Phase I research will verify the benefits of nano-texturing to pressure-sensitive adhesives, and will demonstrate the potential to refine the formulations and processing conditions of nano-textured pressure-sensitive adhesives to suit aircraft appliqué film applications.

Title:Aerogel Augmented Thermal Protection for Divers' Hands
Abstract:A diver's ability to perform dexterity work is greatly diminished in long duration missions if his hands are cold. Research has demonstrated that protecting a diver’s torso, arms, and legs in cold water diving without simultaneously providing adequate thermal protection to the hands proves futile in maintaining an adequate core body temperature in long duration cold water dives. In extremely cold water diving conventional foam neoprene glove are inadequate for protecting the diver and enabling his mission. These gloves have poor thermal performance, are bulky, buoyant, inhibit dexterity and tactile sensitivity, and are difficult to maintain waterproof. The proposed study will develop a multifunctional passive thermal protection solution for diver’s hands featuring augmented aerogel with impressive thermal performance. Using a new infiltration process, Aspen will transform conventionally engineered liners into augmented aerogel super insulating gloves with outstanding dexterity and durability. Phase II will continue refining the work on the superinsulating flexible glove and will provide development on the system design for additional thermal protection and hand warm-up.

Title:Lightweight, Compact, Heated Glove Insert for Diver Hand Protection
Abstract:Navy divers require thermal protection for their hands in cold water to extend dive durations and to improve manual dexterity. Creare proposes to develop an innovative heated glove insert to improve hand dexterity. The proposed technology uses a very thin glove insert with a high distributed heating power to enhance thermal protection for the hands and fingers, keeping them at a comfortable temperature even in very cold water. Our approach employs a lightweight chemical heater with a very high energy density to provide heat and an innovative heat distribution system to deliver the heat to the hands and fingers. The chemical heater will self-regulate its heating temperature for optimal comfort and safety. The consumable material used in the heater will weigh less than 1 oz. for four hours of operation. The glove inserts will be rugged, compact, lightweight, and easy to use. In Phase I, we will prove the feasibility of our approach by: (1) modeling the performance of the heated glove insert, (2) demonstrating the chemical heater in the laboratory, and (3) developing a work plan for Phase II manned testing. In Phase II, we will build prototype gloves and demonstrate their effectiveness in unmanned and manned testing.

Abstract:In this effort Gerbing's Heated Clothing will propose two or more glove candidates (prototypes) for further development. We intend to separately identify and embody the best glove design and heating system candidates based upon screening of all available technologies. Glove design focus will be to provide a lightweight glove with moderate insulating properties that provides maximum dexterity and tactility to the user. Heating systems selection will be screened using the following criteria: Thermal transfer efficiency, Ability to provide 100% electrical isolation, ruggedness and robustness, and ease of integration. The end prototypes will be fully functioning units. This will provide the end users with two different glove fabrication methods and two different heating systems. The heating systems should be interchangeable in the glove shells. Power, control and electrical connection systems will be considered, but only inasmuch as their integration into the glove system. This is due to the limited time frame available.

Title:Active Heating System for Diving Gloves
Abstract:Divers performing deep submersion operations are often exposed to extreme cold conditions resulting in cold stress. Cold stress impairs diver performance, shortens dive duration, and creates an unnecessary health risk to divers. These issues are exacerbated at the extremities of the human body such as the hands and feet. In many cases divers perform tasks with their hands which require dexterity to manipulate tools and instruments, while cold conditions have an obvious affect on performance. A Heated Diving Glove System (HDGS) is proposed here to address this issue. The proposed HDGS will circulate 35C warm water through tubes sown into the top of diving gloves; thereby heating the back of the divers hand without hindering dexterity. Until now, active heating systems have been impractical due to power requirements and reliability. Through a current SBIR program with NAVSEA, Rini Technologies, Inc. (RTI) has developed a breakthrough active Free Diver Heating System (FDHS) that utilizes miniature heat pump cycle technology. The FDHS is an extremely power efficient heat pump design that regulates water temperature circulating through a diver’s tube suit. This effort will leverage the FDHS to supply warm water to the proposed Heated Diving Glove System.

Title:A fast response, open flow, integrating nephelometer for fine scale measurements of aerosol and cloud particles
Abstract:An integrating nephelometer is proposed that can be deployed on a variety of platforms including powered aircraft and towed vehicles. The design allows air to pass freely through the sample cell with no restrictions. A sampling rate of up to 100 hz will allow for aerosol flux measurements. The light scattering coefficient will be measured at multiple wavelengths to provide angstrom coefficients allowing for estimation of the average concentration and size of the atmospheric particles. The phase I objective will be to build a prototype unit that demonstrates the concept and evaluates the measurement sensitivity as a function of the design parameters. The simplicity of this instrument will lend itself to deployment on aircraft towed sondes for particle flux or fog visibility measurements near the ocean surface. The light weight and low power consumption of the instrument also make feasible for use on UAVs.

Title:Metamaterials for Acoustic Cloaking
Abstract:Acoustic cloaking – the ability to direct sound completely around an object – is an exciting possibility. Potential military applications include making underwater objects invisible to threat sonar and creating quiet zones where, for example, otherwise noisy manned underwater operations can be safely carried out or where battlefield noise can be contained. Commercial applications are almost limitless. Metamaterials have been well described in the literature and some electromagnetic prototypes have been demonstrated. The key to making an acoustic metamaterial is anisotropy of its effective material properties. Very recently, designs for underwater spherical and cylindrical cloaks have been developed requiring that the effective density of a material be described as a tensor, that is, that it have two different values depending on direction. In this proposed project, a means to construct metamaterials with this property using very simple, inexpensive and rugged dynamical elements commonly used for vibration reduction will be demonstrated. A promising naval application will be identified and a suitable metamaterial and cloak geometry will be designed for it. A test model representative of the metamaterial will be built and tested in air as a proof of principle. This model will be tested in water in the Phase I option.

Title:Engineered Metamaterial for Acoustic Cloaking
Abstract:To address the Navy need for acoustic cloaking, Physical Optics Corporation (POC) proposes to develop a new Engineered Metamaterial for Acoustic Cloaking (EMAC) technology. It is based on directional density and compressibility variation with a unique structure construction. The innovations in the EMAC sublevel structure offer the Navy a 3D acoustic cloaking spherical shell capable of enclosing various objects, and eventually an elongated 3D shell for objects such as submarines. The EMAC constituents adjust directional properties to change density and compressibility, providing an anisotropic mass density with principal axes and a radially dependent bulk modulus. In Phase I POC will develop a physical model for EMAC, a validation model, a set of optimized parameters for EMAC fabrication/design appropriate for Navy acoustic cloaking applications, and demonstrate a functional component(s) of the EMAC. Based on the feasibility demonstration, in Phase II, POC plans to develop an optimized model of EMAC materials to exhibit cloaking properties at Navy acoustic frequencies and to fabricate a laboratory proof-of-concept prototype demonstrating the ability to manufacture metamaterials in small lots.

Title:Metamaterials for Acoustic Cloaking
Abstract:New metamaterials promise to improve radically the ability of structures to evade sonar detection. The physics of these “acoustic mapped metamaterials” (AMM) is novel: by careful design of their elastic properties, a coating made of AMM materials guides waves around and away from a “cloaked” internal region, rendering the object inside undetectable by active sonar. Like all technologies, AMM will require considerable effort before it becomes a practical reality. AMM theory has only recently been cast in a usable form, by Norris (“Acoustic Cloaking Theory,” Proceedings of the Royal Society A, online May 2008, doi: 10.1098/rspa.2008.0076); previous theories based on extensions of electromagnetics are not physically realizable. Consequently, we propose to conduct extensive numerical experimentation and development to minimize risk. The AMM theory will be deployed to a well-verified finite element code, PZFlex . This development will enable us to test the AMM theory on submarine-like shapes. In addition, we propose to conduct finite element studies of AMM microstructures, in order to ensure that the proposed materials exhibit the desired, complicated and unique elastic properties. These unit-cell analyses will guide the design of manufacturable composites. Finally, our proposed work includes detailed consultation with established manufacturers of naval composite materials, to ensure the AMM microstructures can be manufactured at full scale and low cost.

Title:Comprehensive data-reduction and analysis package for cloud and precipitation particle imager data.
Abstract:An efficient, user-friendly, well documented data processing and analysis software package is needed to process the complex data produced by new airborne particle imaging probes, such as the SPEC 2D-S, cloud particle imager (CPI) and 3V-CPI probes. For example, the 3V-CPI, which combines features of the 2D-S and CPI, integrates data from the 2D-S probe plus images from a 1 Megapixel digital camera at 500 frames per second, amounting to a data rate exceeding 6 billion pixels per second. The very large data throughput and signal processing from these instruments require sophisticated and efficient software to process and interpret the collected data. Furthermore, software developed to process and analyze data from these probes must be standardized, user- friendly with clearly defined algorithms that are understood and available to the entire research community. SPEC Inc., the developer of the 2D-S and 3V-CPI probes, has already made significant inroads in the development of low-level code that analyzes the copious parameters associated with each particle imaged by the 2D-S and CPI probes. These low-level codes perform several functions, including decompressing images that have been compressed in hardware, analyzing several housekeeping and individual particle image signals, such as the particle arrival time, transit time, focus value, particle location on the array(s), deadtime in overload conditions, particle maximum length, width, area and perimeter, reject particles that are too closely spaced due to shattering on probe inlets, to name only a few examples. However, these codes have been written largely for the purpose of the company’s internal engineering evaluation of the performance of the probes. SPEC has also developed particle habit classification schemes for the standalone CPI. In Phase I, we will standardize and enhance the 2D-S codes to have straightforward point-and-click user interfaces and a first-cut technical manual. The final Phase I product will enable users of the 2D-S to select various community standard artifact rejection algorithms, display particle size distributions using selectable imaging processing techniques, compute derived parameters such as extinction, liquid and ice water content and effective particle radius. The CPI particle classification schemes and other candidate schemes will be evaluated for implementation in Phase II. The code developed in Phase I will output the particle size distributions and derived parameters in ascii format for input into archive files. The feasibility of commercializing the final software product will be evaluated. In Phase II, we will extend the software package to include data from the 3V-CPI, finalize the various software components and combine them into a user friendly, menu driven package with graphical displays. The package will be tested with real data and its functionality will be demonstrated. A plan for transitioning the package to commercial use will be developed.

Abstract:In some conditions, flow excited bioluminescence caused by a submersible, diver or Unmanned Underwater Vehicle (UUV) can be observed at the surface, compromising clandestine operations. This project describes a design for a compact, robust, low power device that will measure a bioluminescent signature, the turbidity and depth of the operator and provide a simple prediction as to the likelihood of observation of that signature by an observer at the surface. The device is simple in concept and operation and provides feedback to the user in the form of a simple graphical interface. Use of the device will allow the operator to change speed, depth or course to minimize the signature, thus decreasing the probability of detection.

Our envisioned BRDA will include 1) a suite of simple, compact, low power sensors, 2) a data acquisition and processing system to integrate measurement streams and apply a simple radiative transfer algorithm to determine bioluminescence detection risk, and 3) a simple, graphical user interface to display real-time threat risk. In this Phase I proposal, we provide a description our proposed measurement suite, a bioluminescence contrast model, and a conceptual framework for the user interface. As part of our efforts, we will conduct a series of field experiments to demonstrate the feasibility of the proposed BRDA system from which we will develop a detailed design concept for implementation of the BRDA system for an AUV.

Title:Tethered Antennas for Unmanned Underwater Vehicles (UUVs)
Abstract:When submerged, unmanned undersea vehicles (UUVs) have difficulty with navigation and communication: inertial navigation systems can be used but they are subject to drift the longer the unit remains below; communications are limited to low bandwidth acoustics or wiring back to another vessel or shore platform. A tethered antenna system which allowed RF antennas to remain above water but connected to a UUV below could provide a bi-directional, high data rate link to a nearby vessel or shore platform as well as GPS coordinate data for more precise navigation. A concept and implementation plan for a buoyant, tethered antenna system is discussed in this proposal. Key features include a hydro-dynamically stable surface platform with minimal drag and weight for RF antennas, low cost commercial electronics providing 802.11 wireless communications and GPS data to the UUV, and a strong yet small, lightweight tethered cable capable of reeling the system between the UUV and the surface.

Title:Tethered Antennas for Unmanned Underwater Vehicles (UUVs)
Abstract:When an AUV is underwater it cannot receive a GPS signal and it cannot communicate utilizing radio. This is a problem for users of AUVs. The ability to communicate rapidly and in real time, while still submerged could be very beneficial to many applications. A towed tethered antenna that will support two-way RF communication and GPS reception would greatly enhance the ID and localization capabilities of all AUVs. The immediate benefit to AUV users would be real time commands to the vehicle, which would allow mission changes “on the fly”. Accurate location of the vehicle while patrolling in smaller bodies of water and harbors will now be possible because of accurate GPS fixes.

Title:Retractable UUV Antenna Buoy with Smart Tether GPS
Abstract:KCF Technologies, in collaboration with Star-H and Penn State ARL, will fabricate a tethered antenna to support two-way RF communication and GPS reception. In addition, the module will incorporate a “watch circle error” position correction using KCF Smart Tether sensors on the tether, to project the buoy GPS accurately onto the submerged UUV. In Phase 1, KCF and Star-H will fabricate and test a preliminary deployable antenna. The prototype will be configured as a module for the Bluefin 21 UUV. During Phase 2, Penn State ARL and Bluefin will support a demonstration of the deployable antenna module on a Penn State UUV and the Bluefin 21, respectively. The eventual goal is to also integrate the module onto the Bluefin 12 and other 12 ¾ inch UUVs.

Title:A Tethered Antenna System for High Data Rate UUV Communications
Abstract:In this SBIR Phase I program, NanoSonic would work with a major research university and a large DoD prime contractor to investigate the application of tethered antennas to UUVs. Through this program, NanoSonic’s team would perform system design and feasibility studies as well as produce designs and limited hardware prototypes for use in tethered communication systems for UUVs. NanoSonic’s PI is an antenna engineer with familiarity in RF electronics and fiber optic systems. He would lead the design and construction of the required antennas and electronics. NanoSonic’s President, Dr. R.O.Claus has specific experience in fiber optic system design, fiber fabrication and fiber optic cable deployment and would assist with the tether dynamics. NanoSonic also has significant experience in the construction of structural composites with radome qualities for RF and microwave transmission. Other value-added features would include hydrophobic coatings and printed antennas. The university partner brings a long history of UUV development and system construction as well as hydrodynamics and buoy construction. This partner would provide a convenient and useful platform for feasibility and proof-of-concept design, development and testing. Finally, the NanoSonic group can support restrictions applied to this program.

Title:Fiber Optic Tethered Antennas for High Speed Communication with UUVs
Abstract:Underwater acoustic communications for UUV control and information retrieval is power intensive and can not operate at high data rates comparable to RF communications. In order to improve communication with submerged UUVs, Physical Sciences Inc., is proposing to develop a tethered antenna buoy. The buoy will house the RF antennas, can be deployed and retrieved as necessary and allow high rate bi-directional data communication up to 30 meters. The design of the system features an innovative dual antenna design and the use of optical fibers for communication between the buoy and the UUVs.

Title:Next-Generation Marine Atmosphere Observing Instrumentation
Abstract:The overall objective of this Phase I program is to develop the architecture for a satellite data uplink system for transmitting dropsonde measurement data from the sensor to a ground-based terminal without the use of a specialized receiver or direct line-of-sight radio links from the sonde to the host aircraft. This project is intended to complement the high-altitude, automatically ejected dropsonde system, XDR-928ds variant, being developed by Yankee Environmental Systems (YES) by providing a reliable non-direct radio data link between the YES sonde and the ground based users. The resulting satellite uplink device, SatSonde, will replace the standard point-to-point link used on the current XDR-928ds dropsondes (radio transmitter in sonde and corresponding AirHub receiver in the launching aircraft) with a satellite uplink system that will push the data from the sonde through an existing orbiting satellite data network and to the end-user through a web-based data dissemination service.

Title:Next-Generation Marine Atmosphere Observing Instrumentation
Abstract:In day-to-day military and commercial operations, obtaining high fidelity METOC observations of the operational space for forecast systems is difficult. One must dedicate sensors and collection resources, and the communications to convey the information to introduction into the METOC forecast system. Obtaining these METOC observations in data sparse and denied operational areas (OPAREAs) for the forecast system is very difficult, because the applications of all the resources in the operation area are optimized and deployed for accomplishment of the primary mission. Although supporting operations such as collection of METOC data can be important to the success of the mission, adding resources to uniquely collect METOC data is often prohibitive. We will exploit the METOC data observing capability of small Unmanned Aerial Systems (UASs) used on the battlefield, and those soon to be used in small commercial markets. From the UAS’ autopilot, quantifiable low-level/boundary layer METOC data (wind, temperature, and pressure) are available, and the derived METOC information (turbulence, visibility, wave heights, area surface thermal characteristics, and cloud types and amount) are also available and ready to be exploited.

Title:SESI Lidar Wind Profiler
Abstract:We propose to develop a small wind profiling lidar based on SESI and NASA technology that also produces boundary layer, cloud height, and cloud fraction data products. The wind measurements are based on the well established technique of aerosol structure time-lag correlation using a simple elastic scattering aerosol lidar. Accurate and timely cloud parameters (cloud fraction vs. altitude, ceiling, and altitudes of multiple layers) are also obtained using spatial scanning or sampling strategies that are superior to the data obtained from either whole sky imaging cameras or fixed single beam laser ceilometers. SESI is one of the few companies that have transitioned atmospheric lidars to DoD operational readiness, and is pursuing a program to develop wind lidars for multiple DoD and civilian applications. Using pulsed laser beams projected from a small telescope and range gated detectors, we are able to remotely measure 2-D and 3-D wind vectors at contiguous range intervals along a given line of sight without the use of expensive heterodyne or other Doppler technologies required by many other wind lidar systems. The technology is simple, robust, and builds on decades of development by several groups using scanning aerosol backscatter lidar.

Title:Next-Generation Marine Atmosphere Observing Instrumentation
Abstract:The need for atmospheric pressure, temperature and wind (PTU+wind) vertical profile data over the data sparse open ocean remains a significant problem. Ship-based upper air stations provide synoptic observations but also act as homing beacons for the fleet. Few air-deployed dropsondes are deployed—usually only in hurricanes by specially- equipped WP3 and C-130 aircraft. Future advances in the accuracy and capability of Numerical Weather Prediction (NWP) models, particularly in littoral regions near large population centers, hinge heavily upon accurate initial condition data. This data can ideally be provided by in-situ dropsonde observations. What is needed is a low cost and reliable mechanism to enable more routine at-sea soundings. We propose to develop a highly rugged dropsonde technology that is mechanically-compatible with the thousands of ALE- 47 electronic countermeasure dispensers widely deployed across multiple DoD manned and unmanned aerial vehicles. The miniature dropsondes will be preloaded into one or more ALE chambers and automatically activate upon release. While in flight, the dropsonde will telemeter PTU, GPS winds, and sea surface temperature to low earth- orbiting data satellites. Near real time data will feed sounding data to the Fleet Numerical Prediction center's NPW models. We call this concept the “Automated Dropsonde Atmospheric Measurement System” (ADAMS).

Title:An Asynchronous SINCGARS (Single Channel Ground and Airborne Radio System) Frequency Hopping Notch Filter Based on Canceller Technology
Abstract:Navy SIGINT systems are required to receive low level signals in the HF, VHF and UHF frequency bands. The SINCGARS (30-88 MHz) band occupies part of the VHF frequency band where signal reception is required. U.S. Navy ships will have from 2 to 8 SINCGARS transmitters installed, which are used to communicate with shore operational units. SINCGARS (Single Channel Ground and Airborne Radio System) radios use a frequency hopping signal to prevent jamming and interception, which is difficult to remove and prevent electromagnetic interference to the SIGINT receivers. GIRD Systems has developed an innovative approach that is capable of mitigating such SINCGARS interference without needing a copy of the interfering signal. The proposed approach will meet the space and volume requirements.

Title:An Asynchronous SINCGARS (Single Channel Ground and Airborne Radio System) Frequency Hopping Notch Filter Based on Canceller Technology
Abstract:Design proposed for reducing SINCGARS co-site interferers. Design uses 8 high-Q 5- zero notch filters with unique design techniques for very high Q. It uses 8 bandpass filters covering 1/8th the band for fast interferer acquisition. Once an interferer is recognized using log detectors and a microprocessor, the notch filter is tuned to the interferer for rejection. Unique techniques are also employed for the band-pass filters. The design approach will meet all of the system requirements.

Title:Prioritized Unbalanced Traffic Total Yield (PUTTY): and Optimal Approach to Topology Management in Directional Networks
Abstract:Mayflower Communications Company, Inc. (Mayflower) proposes a Topology Management technology, the Prioritized Unbalanced Traffic Total Yield (PUTTY), to meet the Navy objective, namely, to develop advanced approaches for readily deployable Topology Management algorithms that address the complexity of mobile Ad Hoc Mesh Communication Networks constructed of directional antennas, and demonstrate its ability to optimize total network carrying capacity in a tactical ad hoc environment with unbalanced traffic. The proposed PUTTY topology management includes (1) network monitoring and analysis algorithms, and (2) network topology optimization algorithms. These two categories of topology management algorithms are applied repeatedly to dynamically optimize the network topology. Low complexity of the algorithms ensures that the proposed topology management is able to manage networks with hundreds of heterogeneous nodes. The proposed PUTTY technology leverages Mayflower’s expertise in network design and topology management, and builds on technology developed under several SBIR programs and Internal R&D. The PUTTY system, 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 PUTTY system in Phase I and II, and ensure its commercialization in Phase III and beyond.

Abstract:The topology of an ad hoc network plays a key role in the performance of many control algorithms used in the network for purposes such as scheduling of transmissions, routing, and broadcasting. The goal of topology management is to maintain network configuration in terms of wireless links to optimize bandwidth allocation. This Phase I SBIR proposal will pursue both `power control' and `hierarchical topology organization' approaches to to research and develop readily deployable topology management algorithms which address the complexity of mobile ad hoc mesh communication networks constructed of directional antennas, and demonstrate, via extensive QualNet simulation, their ability to optimize total network carrying capacity in a tactical ad hoc environment with unbalanced traffic.

Title:Topology Management Analysis and Algorithms (TMAA)
Abstract:TUG’s proposed solution to the Topology Management for Directional Antenna-based Networks (DA-Nets) applies the concept of clusters to the formation and optimization of network topologies. The decentralized control approach required by military applications of DA-Nets requires the distribution of information across the network such that each node can calculate the topology based on a shared view of the network and its traffic patterns. A cluster associates nodes performing related functions, which is both a natural basis for creating topologies and a method for reducing the computational complexity of managing DA-Net topology. A valuation function is defined which calculates the value of a network configuration based on utilization requirements (e.g., network traffic). The solution utilizes optimization algorithms to optimize inter and intra- cluster connectivity based on the ‘value’ criteria calculated by the valuation function. The end result is a self-optimizing network topology which is constantly seeking to improve its own ‘value. The work performed in this effort will: - Examine options for implementing the Valuation Function which assess network value - Tailor existing TUG optimization algorithms for DA-Net application - Define the information and message exchange requirements necessary to perform distributed topology management

Title:Imaging Instrumentation System
Abstract:DBV Technology, LLC proposes to develop an acoustic instrumentation system for the Test & Evaluation of Trident D-5 munitions to support the geo-location of near simultaneous impacts on the sea surface of up to 500 projectiles within a 500 meter radius area to an accuracy less than 1 meter CEP referenced to WGS-84. The proposed system will leverage over ten years of DBV Technology experience in basic and applied research of the acoustic signatures produced by high velocity solid objects impacting gas-liquid interfaces such as the sea surface. It is shown that by applying the first principle physics governing the acoustic signatures of impact events in conjunction with advanced signal processing techniques, state of the art electronics, storage, and acoustic sensor technologies; individual impact events can be resolved (i.e. detected and scored) to within 8 cm spatially or 50 micro-seconds temporally. In addition to the research of splash acoustics, DBV Technology has over ten years experience with design, development, installation and operation of ocean acoustic systems for splash detection and scoring to sub-meter accuracy in support of test and training at the Atlantic Undersea Test and Evaluation Center (AUTEC), Pacific Missile Range Facility (PMRF) Naval Gunfire Scoring System (NGSS), Kwajalein Missile Impact Scoring System (KMISS), Soft Impact Location Capability (SILC), and Integrated Maritime Portable Acoustic Scoring and Simulator (IMPASS) System.

Title:High Precision System for Scoring Multiple Simultaneous Water Impacts
Abstract:Acoustic scoring systems based upon time difference of arrival (TDOA) have long been used to score in near-real-time the drop accuracy of precision munitions in the open ocean. These systems work well when they are scoring a single impact but do not have the capability to discriminate multiple and near simultaneous impacts. Physical Sciences Inc. (PSI) proposes to develop a High Precision System for Scoring Multiple Simultaneous Water Impacts (HPSS) by fusing data from multiple sensor sources. Fusing multiple sensor sources reduces the total number of potential solutions evaluated and helps eliminates “phantom sources”. In addition, the fused sensor approach minimizes the probability that an impact falls into a region where the impact is either shaded or of indeterminate position.

Title:Determination of SSBN ownship ground velocity
Abstract:Precise navigation is crucial to the Navy's submarine fleet, as is the ability to keep each submarine submerged and covert. All INS systems drift, and require additional inputs to correct the drifting navigation. In this Phase I, ISL will research two innovative electromagnetic velocity estimation methods that are independent of current technology, and will add valuable information to stabilize the onboard INS: (1) the usage of electric field (E-field) measurements and the Lorentz force relationship relating the E-field and the ambient magnetic field to velocity; and (2) the usage of separated magnetic gradiometer sensors to determine the speed that the submarine is passing through the magnetic field caused by underlying oceanic crustal structure. Each method is extremely covert. The Lorentz method measures small voltages induced in three orthogonal wires inside the submarine, while the gradiometer method utilizes external magnetic sensors. We predict that the derived velocity accuracies from these methods may be as good as 0.5 cm/sec. The Phase I project will study feasibility of each method, will estimate the accuracy of the derived velocity, will identify the major noise sources which can affect the velocity estimate, and will determine the optimal sensors and configuration to achieve the objectives.
