Title:Engineered Intumescent Coated Textile Materials for Improved Comfort and Thermal Protection
Abstract:Engineered Yarns (EY) proposes Engineered Intumescent Coated Textile Materials for improved thermal protection for the Marine. Although in use for 50 years, Intumescents have been confined to mostly paints, industrial insulation and coating industry. Intumescent materials have a unique characteristics, on the application of heat they produce a foamed structure, char like residue. Foam structures are good insulators and good barriers in preventing heat transfer. Well-formed Intumescent foam only 1/32” can reduce the heat from flame at 1368F to 572F on the back side. Such a reduction in heat would be enough to prevent most all fiber types from igniting. EY plans to develop two forms of Intumescent coated textile materials – Intumescent Coated Fabrics and Intumescent Coated Yarns. The Engineered Intumescent Textiles can be integrated into Marine ensemble for improved thermal and comfort performance. EY plans to develop Intumescent textiles in conjunction with No Melt No Drip fibers to enhance overall thermal protection for the Marine. EY proposes to integrate this engineered Intumescent functionality in all layers of ensemble to generate redundant F/R protection for the Marine. EY’s proposed solution provides improved thermal protection, low risk, fast commercialization and cost efficient alternative to Nomex based systems.

Title:Development of a Lightweight, More Comfortable, and Durable Clothing Ensemble with Improved Flame-Resistant Properties
Abstract:Current Marine Corps combat utility uniforms are not flame retardant. They do not self- extinguish after a flame exposure, which can lead to increased burn injuries. Furthermore synthetic materials, used in many types of garments, can melt and fuse onto the skin causing serious burn injuries in a flash fire. Improvised Explosive Devices have become common in combat today exposing soldiers to extra risks of injury, due to flash fire and extreme heat exposure. Improvements in the flame retardant properties of Marine Corps uniforms are desired. Existing techniques for producing flame retardant clothing have significant limitations. Either they are bulky and uncomfortable, or the flame retardant properties are diminished over time with normal use, due to the fact that flame retardant additives are often not permanently fixed to the clothing material. This Phase I project aims to develop flame retardant textiles using a new class of flame retardant chemicals, that uniquely inhibit the combustion process by a multiplicity of mechanisms. Key to the approach is the ability to permanently attach the flame retardant chemical to the clothing material for high durability. Favorable aspects of the new class of flame retardant chemicals also include little or no toxicity, no environmental hazards, and ready availability from commercial sources. In Phase I, we will generate textile materials that have the desirable physical properties for comfort (i.e., mechanical strength, flexibility, breathability etc.) and offer a high degree of fire protection. An alliance with a leading protective clothing manufacturer has been established for rapid transition of this technology from research to production.

Title:Software-Defined Universal Battery Charger and Eliminator
Abstract:The United States Marine Corps have adopted Distributed Operations as an effective way to fight the Global War on Terrorism. Electronic devices enable Distributed Operations by connecting squads to each other and to their commanders. However, as the suite of electronic devices that is taken into warfare is growing, the infrastructure needed to support the electronics is lagging behind. This has resulted in military battery shortages and logistics problems ensuring electronics are paired with compatible battery adapters and chargers. Mainstream proposes a truly “universal” battery charger/eliminator for which the charging requirements of a battery can be defined in software, and the charger hardware will carry out the charge accordingly. The system will automatically be able to connect to the Mainstream Power Manager without any additional adapters. To make a connection to a battery without an adapter, “bed of pins” is used. In Phase I, Mainstream will develop a working proof-of-concept that will allow this technology to be implemented.

Title:Power Suite for Distributed Operations
Abstract:Packet Digital's innovative solution is to develop a Power System Liaison (PSL) that can interface the numerous power sources carried by the warfighter or encountered during mission activities with the C-E systems used by the warfighter or the batteries that power said equipment. The goal is not to redesign or invent new power generating sources or improved C-E equipment, but rather develop a method and device for interfacing existing C-E equipment to existing power sources such that power sources are consumed with maximum efficiency and C-E systems are operated with a high degree of reliability. Technologies developed for On-Demand Power solutions allow the Packet Digital PSL to have unmatched performance with minimal weight and volume footprints. The advantage of the PSL is that it can intelligently manage the flow of power between multiple power sources and multiple loads. An additional benefit of the PSL is that it will eliminate the need to carry additional battery chargers. A rechargeable battery can be connected directly to the power output of the PSL, and the PSL will automatically charge the battery with the optimal current and voltage waveforms.

Title:Flexible, Lightweight, Intelligent Power Distribution System
Abstract:To address the Navy’s need for a reconfigurable kit of power options to optimize energy usage in dismounted operations, Physical Optics Corporation (POC) proposes to develop a new Flexible, Lightweight, Intelligent Power Distribution System (FLIPD). This proposed system is based on an enhanced version of POC’s proven wearable connector technology to provide plug-and-play compatibility with virtually all electronic devices. The embedded sensors and circuitry in the connectors adjust electrical requirements “on the fly” for each device, while also powering and monitoring/regulating the energy usage, ensuring efficient operation and giving priority to mission-specific equipment in case of low energy reserves. The innovation in FLIPD will provide true plug-and-play compatibility with all standard military equipment to regulate and monitor energy usage, while also providing secure and robust mounting pouches that allow the soldier to position equipment anywhere on their uniform. In Phase I, POC will demonstrate the feasibility of FLIPD by connectorizing several electronic devices (i.e., GPS, PDA, radio) and monitoring/regulating the power usage with statistical data output to create mission-specific energy models and distribution. In Phase II, POC plans to develop a wearable power distribution architecture to regulate and power a complete outfit of electronic equipment.

Title:Integral Suppressed Weapon Barrel
Abstract:In an armed engagement, the first few seconds are often critical. Suppressed systems allow US assets to engage the enemy without giving away their position. During combat at night with our night vision devises, we own the night until we pull the trigger. Without suppressed systems, the enemy will fire at our muzzle flashes and inflict casualties without the need for night vision equipment. The goal of our SBIR project is to achieve the benefits of a suppressed system without changing the balance of the weapon. This implies more than is stated. A well balanced suppressed weapon that is not reliable and accurate is hazardous if not entirely useless. To reach the stated goal, the suppressor design must be mated to the design of the weapon in question. We will design suppressor systems for the M-16 and M-2 weapons systems that outperforms existing state-of-the- art suppressor systems in the areas above.

Title:Integral Suppressed Weapon Barrel
Abstract:Reducing muzzle noise and flash from military and police firearms provides a significant tactical advantage in the field. Existing suppression technology reduces noise, but comparatively little science exits to explain how current designs can be advanced to provide enhanced suppressor performance. Furthermore, even less design guidance exists that can lead to integration of suppressors into a firearm’s barrel assembly, as envisioned by the Marine Corps and other military and civilian agencies. Lessons learned as a result of the ongoing conflicts in the Middle East have indicated that increased use of current suppressors, as part of everyday operations, have led to shortened life cycles of suppressors, increased maintenance (and sometimes damage) of weapons, and considerable variability in weapon accuracy. FloDesign, Inc. and its large business partner, FN Manufacturing, LLC (FNM), have successfully completed (i.e.in July of 2007), a series of tasks to investigate and advance the understanding and science of noise/flash suppression, suppressor self-cleansing, and generally determine the feasibility of applying aerospace mixer/ejector science to muzzle blast suppression. It was, incidentally, noted that noise and flash suppression are closely related components of the muzzle blast. This SBIR effort will apply the design guidance gained previously to integrated barrel suppressors.

Title:Integral Suppressed Weapon Barrel
Abstract:Innovations Plus seeks to dramatically reduce hearing damage associated with small arms fire in the USMC. Noise induced hearing loss is on the rise for U.S. servicemen and women. In 2004, the VBA paid out more than $400 million for service related auditory disabilities. Scientific methods and processes will be utilized to research, design, build and test an Integral Suppressed Weapon Barrel (ISWB). Such a device must be small enough to utilize existing accessories without modifications yet big enough to meet expectations. Our team has the “know how” and the tools to solve this problem. The Co- Investigator’s patented process can reduce typical barrel and suppressor weight by 35% without compromising structural integrity and increase heat dissipation by a factor of 3.7. The resultant product is lighter with an increased life span. Our T&E consultant is the best. Mr. Alan C. Paulson has published hundreds of articles and four books regarding suppressors. He will thoroughly evaluate our brassboard before it is delivered to the USMC for feasibility verification. Once commercialized, our ISWB will significantly reduce noise induced hearing injuries from small arms fire and improve the soldier’s situational awareness. This will save millions of dollars each year.

Title:40mm Low/Medium Velocity Air Bursting Munitions System (2007050)
Abstract:Most small/medium caliber munitions operate as point-detonation weapons without an air- burst capability which limits their effectiveness against hidden targets, scattered targets, and foot soldiers. The effectiveness of those weapons could be improved significantly by adding an air-burst capability to those munitions. A more effective approach is an active proximity sensor built into the projectile itself. Such proximity sensing fuze requires a miniaturized radar transceiver that is small enough to fit into the projectile and operates with little prime power. In the past two decades, Hittite Microwave Corporation has developed MMIC-based radar transceivers for such applications. Today, Hittite’s MMIC sensors are used in a wide variety of fuzes in munitions including: M734A1, XM782, EX419, and DSU-33. Hittite’s continued effort to miniaturize and reduce the power consumption led to demonstration of a proximity fuze for M-80 sub-munitions (EX433). More recently, Army developed an air-bursting fuze for 40-mm munitions using Hittites’ miniaturized low-power MMIC transceiver. Hittite proposes to utilize its established FM-CW Radar MMIC transceiver technology and combine it with a signal processing technique developed for automotive pre-crash applications that utilizes unique patented algorithms specifically designed to accurately predict the offset in trajectory of on-coming targets using a static antenna radiation pattern. Hittite algorithms are based on the mapping of synchronously detected Doppler in two or more range bins of a predetermined zone, and all calculations are done without the use of multiplication or division so that the technique can be implemented using simple commercially available RISK microcontroller for closing velocities in excess of 2000 m/s. Hittite Microwave Corporation is a manufacturer of fuze sensors with a history of supplying more than 1.5 million MMIC transceivers. Hittite is also a supplier of low-cost MMIC parts to the commercial market with a long established track record of transitioning its R&D results into commercial products.

Title:Smart Optical Proximity Fuze
Abstract:To address the U.S. Navy Marine Corps need for a new generation of 40 mm low/medium- velocity munitions that could provide higher lethality due to airburst capability, Physical Optics Corporation (POC) proposes to develop a new Smart Optical Proximity Fuze (SOProF) for 40 mm rounds. This proposed SOProF is based on two POC innovations: (1) use for the first time of a new optical fuze design for low-velocity 40 mm rounds, and (2) novel integration of state-of-the-art optical and optimized electronic components. These innovations, utilizing the principle of laser triangulation, will enable the new airburst 40 mm projectile to hit camouflaged and defilade targets without any fuze preset and with minimal modification of the fire control system. SOProF will activate a round payload at the required distance of 2-3 m from the target. In Phase I POC will design and build a prototype SOProF, making maximum use of COTS components, and will demonstrate the feasibility of the SOProF prototype by laboratory and field testing with dummy practice rounds. In Phase II POC plans to optimize the SOProF design for assembly with HE M-406 and M433 40 mm projectiles, and will conduct range testing in cooperation with the customer.

Title:40mm Low/Medium Velocity Air Bursting Munitions System
Abstract:The purpose of this proposal is to assess the use of Micro Power Radar (MPR) to aid in providing the individual Marine Infantryman with air bursting munitions to enhance his battlefield effectiveness. Current fuzes compute the time of flight and set the fuze for a time or counting revolutions with an input to the system to tell it to detonate after a specific number of turns. These technologies allow for significant variability in the actual height of the airburst thereby limiting the expected effectiveness. The addition of non-inertial sensors to the munitions could ameliorate the problems faced by current fuze technology. Based on emitting and detecting very low amplitude and short voltage impulses, MPR has a sensitive window for accurately detecting reflections from boundaries and could be implemented as a smart fuze that always knows how far the round is from the impact point. Designing a fuze that can be depended upon to burst at 2 meters (or another to be determined specific value) from the target would greatly increase the effectiveness of the round. A fire control system or possibly a weapon upgrade kit that attaches to the current legacy systems device for programming the round’s impact height if variability is part of the design. Beyond using MPR for smart fuzes, it could be applied to munitions testing or other impact testing in the commercial sector.

Title:Low Profile Multimodal Acoustic Treatment
Abstract:The noise signature of the USMC Expeditionary Fighting Vehicle (EFV) is excessively high for human safety factors, and impedes stealthy land operation which places military personnel at high risk of detection by adversaries. A dominant contributor of the noise is due to the air-cooled heat exchanging system that draws a large volume of air through a compact space in a short period of time. For this Phase I project, Infoscitex proposes to develop new broadband noise abatement materials that could be retrofitted to the EFV to counteract airflow generated noise. Phase I activities will involve analyzing the cooling subsystem for noise generation locations, producing novel materials with enhanced absorption capabilities, performing acoustic tests on materials, and developing a design concept that integrates these material into the cooling sub-system.

Title:Air Flow Noise Reduction Techniques
Abstract:The Expeditionary Fighting Vehicle (EFV) currently is extremely noisy. The goal of the proposal is to reduce noise produced by the cooling system for the engine, which consists of fans,heat exchangers, and ducting to the outside. Mezzo is developing mirco tube heat exchangers that provide a much improved ratio of heat transfer/pressure drop compared to conventional heat exchangers (i. e. plate-fin heat exchangers). Mezzo's approach to reducing noise is to replace the heat exchanger currently in use with one that will meet the heat exchanger specifications, while reducing dramatically the pressure drop across the heat exchanger. Reducing the required positive pressure generated by the fan will make it possible to use much quieter fans, as well as fans that require less power. Quieter fans will result in a much quieter system.

Title:Low Noise Axial Fan Optimization for the Marine Corps Expeditionary Fighting Vehicle
Abstract:The Marine Corps Expeditionary Fighting Vehicle (EFV) experiences excessive air handling unit noise and the cooling fan does not meet the requirements that have been established for its operation. During the past fifteen years, substantial progress has been made in noise mitigation through the use of computational fluid mechanics (CFD). In particular, the automotive industry has invested millions of dollars in engine cooling systems in order to provide more quiet fans that will go in their automobiles. A major technique that has been applied to the rotating blades of fan systems in order to suppress noise is the technique of “sweeping” the blades. MSI proposes to use a swept rotor blade in order to suppress the noise of the EFV fan. In order to maximize prototype development, MSI will utilize new aero-acoustic software that when coupled to CFD will predict the sound levels produced by a rotating blade row. Traditionally, designs have been performed using CFD and FEA, and then been subjected to experimentation. MSI will use the aero-acoustic software to minimize fan noise along with specialized sound pressure level field testing to back up and confirm the analysis results.

Title:Sniper Detection
Abstract:PALS for Sniper Detection (PALS-SD) is a straightforward near-term evolution of A2-T2’s existing PALS 3D for enhanced long-range facial identification technologies. Essentially, our existing multi-modal Electro-Optical/IR/Laser-Sight/Designator/Range-Finder configurations will be upgraded to include an eye-safe pulsed laser and sensor that discriminately detects reflections from eyes and optics. Further our software will remove most animal eyes detected based on eye reflection signatures. Our multiple modes enable reliable long-range detection, mitigate false positives, and exceed requirements by including real-time multi-modal confirmation processes options. By design our detection with confirmation processes dramatically reduces the time-delays, risks, physical efforts, and costs currently used to determine if the threat detected is real (via binoculars, UAV, or building physical entry, etc). Our spiral development processes include both virtual simulations and real-world testing. Additionally, the PALS-SD upgraded laser module will also have the option of adding a dazzle laser as required. Beyond discouraging potential threats with non-lethal means, we also provide direct fire aiming enhancements and indirect-targeting data. Indirect-fire data is supplied by our PALS sensor module’s built-in GPS location and orientation, along with returned laser range find data. We include these lethality enhancements in keeping with our internal-mission statement of “Helping enemies have a bad day”.

Title:Sniper Detection
Abstract:Applied Science Innovations, Inc. proposes development of the real-time, Advance- Warning System for Active Detection of Snipers s (AWADS). Unlike existing systems that react after the sniper takes a first shot, the novel AWADS electro-optical system will detect a potential sniper at a distance, before the sniper has a chance to take a shot. Compared to emerging systems based on reflection from optics, AWADS will automatically classify and discrimination between a pair of eyes and a riflescope, and between a casual observer and persistent surveillance. Countermeasures based on anti- reflective coatings on a reticle will fail AWADS, unlike other optical sniper detection systems. AWADS is safer to accidental eye exposure at close range, compared to other systems. It will work autonomously, with no user participation. Detection range will exceed 600 meters, optimized for urban environment. Phase I will produce systems design, algorithm development, and experimental demonstration of AWADS in laboratory conditions and outdoors, to reach technology readiness level 5. In Phase II, a fully functional, preproduction prototype will be built. Commercial marketing plan will be developed. In Phase III, AWADS will be commercial available for defense and civilian commercial applications.

Title:Counter-Sniper High-Speed Autonomous Optical System (CHAOS)
Abstract:The problem of sniper detection and neutralization proves to be one of the more significant issues facing the troops presently deployed in Iraq and Afghanistan today. This unfortunate reality has spurred both industry and the DoD to press for immediate and effective solutions to the detection and neutralization of the sniper threat. In the case of sniper detection the urgency and importance is exemplified by the existence of no less than fourteen different systems ranging between acoustic, passive IR, and active optical search systems designed to address the problem. Areté Associates is proud to offer a unique approach to address the detection of sniper optics and neutralization of sniper threats in a compact robust package that will provide the autonomy currently absent in existing approaches. Areté’s a counter-sniper high-speed autonomous optical system (CHAOS) being proposed here is based on the physics of optical augmentation (OA), occasionally referred to as the “cats eye” effect, and leverages existing Areté program activities in the area Afocal beam steering. Although the physics of OA is well understood in the detection of optical systems, it will be shown that the CHAOS design approach being proposed provides a unique capability with respect to autonomous operation, laser dazzle counter measure, and threat coordinate localization. The overall goal of the project is to prove the feasibility of the proposed design approach through demonstration during the first phase. Additionally, design and analysis will be combined with the demonstration results to show traceability to the objective system design that is to be developed and demonstrated during Phase II of the program.

Title:Holographic Preventive Advanced Counter-Sniper Device
Abstract:To address the Navy need for technology that will detect a potential sniper at a distance, Luminit, LLC proposes to develop a new Holographic Preventive Advanced Counter- Sniper (HoPACS) device based on the latest advances in holography, laser-scanning techniques, and CMOS technology. Based on the Bragg angle selectivity of shift and angle multiplexed thick transmission holograms, and the pattern imaged on a CMOS sensor as a result of illuminating the holograms with laser light, we can produce at least a 120- degree field-of-view sensor in which every hologram pair selects one particular laser beam direction thereby indicating the direction of a potential threat. This laser beam is initially irradiated by a small diode laser, scanned 360 degrees by the miniature scanner, reflected from the sniper’s optics and detected by HoPACS. Three identical sensors will cover a 360-degree field of regard in azimuth and at least 45 degrees in elevation, and will detect and neutralize a sniper with a dazzling laser before he can shoot. In Phase I, Luminit will demonstrate HoPACS feasibility by building and testing a benchtop HoPACS. In Phase II, Luminit plans to build a prototype HoPACS. The resulting system will be commercially available by the close of Phase III.

Title:Preshot Sniper Detection
Abstract:To address the Navy need for prefire sniper detection, Physical Optics Corporation (POC) proposes to develop a new Preshot Sniper Detection (PSD) system that identifies covert snipers before they shoot, even in cluttered urban environments, in <2-3 sec. The PSD system is based on a multimodal, high-resolution, imaging optics package with no moving parts and processing hardware that accurately detects snipers, covering 360 deg. x 45 deg., day and night, at up to 600 m standoff distance, with a minimum false alarm rate (FAR) of <10^3, in a portable form factor (3 in. dia. x 6 in. length, <5 lb.) that operates continuously for >24 hours with a military rechargeable battery. The innovative PSD’s three-step alarm (yellow, orange, red) via sensor modality, autonomously informs Marines of sniper locations/ranges with visual target images. In Phase I POC will demonstrate the feasibility of PSD 360 deg. x 45 deg. detection by building and testing a functional laboratory prototype. In Phase II POC plans to develop a fully functional Phase II prototype to demonstrate its high-probability sniper detection capability.

Title:360 Degree Urban Sniper Warning System
Abstract:In recent years, military engagements have moved from the traditional battlefield to urban or suburban settings. In this environment, security patrols are much more likely to encounter an IED or hidden gunman than an organized (or uniformed) squad of soldiers. The urban warfighter needs the capability to detect potential snipers, at a distance, before they shoot. The challenge is to find potential snipers in a cluttered environment where the sniper may be mostly hidden from view except their eyes, &/or a rifle scope, or gun barrel. Complicating this problem may be non-target glints from a wide variety of sources. SARA proposes a common-housing, Multi-sensor approach to Detection, Recognition and Identification of possible snipers, particularly for friendly units moving through an Urban environment. Some COTS elements will complement essential & unique multi-wavelength optical devices, based on SARA’s imaging and dazzling technologies. Other inventions include electronics and software for detection and cueing. The MSSF system provides an ever-vigilant 360 degree “coverage” such that when a possible sniper is suspected, the MSSF provides an alarm and an annotated image to the operator.

Title:Sniper Detection
Abstract:Present proposal established analytical and scientific basis for the creation of Advanced Mirage Technology. Torrey Pines Logic, Inc. (“TPL”) has been developing Mirage optical augmentation technology since 2001. While the Mirage 1200 unit is currently available as a finished product and has been tested in the field since 2003, there are number of improvements that can be considered for a second generation product. Current Mirage 1200 device provides optical augmentation capabilities to the dismounted operator. Device is portable, hand-held and extends identification of the optical systems pointed at the operator to 1200 meters. At present there are no optical augmentation systems in the arsenal of the dismounted warrior. Most of the effort has been concentrated on acoustical or flash detection (“after/during the shot”), while the information from the theater suggests that any hostile action is always preceded by optical observation. TPL has previous designed and fielded Mirage 1200 system shown beneficial and capable in the field. Of course, Mirage 1200 has been designed with known and available technologies at the time of the concept, thus new approaches can be implemented for major performance improvements. It is desirable to create a next generation of Mirage technology, not only smaller and lighter, but, crucially, capable of very fast operation and identification. The ultimate goal is to scan 360 degrees surroundings in urban terrain in under 1 second. In order to achieve such a goal, new technologies in scanning, beam steering, processing, emitters and detectors have to be considered.

Title:On site sterilizing solution production system
Abstract:Chlorine bleach (a 6% solution of sodium hypochlorite in) is the main disinfectant used in the food service and food production industry. It is also used for water supply treatment. It is inexpensive and available in many parts of the world. The very property that makes it such a good chemical disinfectant also causes problems with shelf life and storage. It is a strong oxidizer; storage container integrity and spills are constant concerns and effective shelf life can be as little as 3 months. This causes major problems for pre- deployment stock storage, stock rotation, staging, shipping, on-site storage and, in the final analysis, reliability regarding disinfectant and sanitization effectivity. Functioning as a direct replacement for commercial bleach, on-site production of mixed oxidants can potentially address these problems. Requiring only water, salt and electricity, such a system would not require the storage, transportation, or use of hazardous chemicals. In addition, a mixed oxidant system could be compact in size, and have low maintenance and life cycle costs. The research that is proposed to evaluate the potential for such a system is seen to build on an extensive base of knowledge that exists in the water treatment and purification industry.

Title:On site sterilizing solution production system
Abstract:Sanitation and disinfection of food products and food-contact surfaces is a major concern of forward deployed military forces. Current DoD protocols call for the use of oxidizing agents such as sodium hypochlorite and other mixed oxidants to neutralize potentially harmful biological compounds. Although oxidizers such as sodium hypochlorite are readily-available in large quantities, their hazardous nature places significant burdens on military operations in terms of transportation and storage. In this Phase I SBIR program, Infoscitex Corporation (IST) and Cascade Designs, Inc. (CDI) propose the development of a device capable of providing the USMC and other components of the DoD with a disinfecting solution derived from non-hazardous precursors that are air- transportable, shelf-stable, and low cost. The Phase I project will focus on the design, fabrication, and evaluation of a laboratory prototype of the device. In Phase II, the development efforts will be expanded to focus on device design refinement, manufacturing technology, and performance evaluations. As a result of the Phase II program, IST and CDI will supply pre-commercial prototypes to the USMC for evaluation.

Title:On-Demand Disinfectant Generator
Abstract:Currently, the U.S. Navy uses a 4wt% sodium hypochlorite solution (bottled bleach) as a general disinfectant/sanitizer in the field. The solution is used for processing fresh fruits and vegetables, water purification, surface sanitizing, and general cleaning use. However, the limited shelf-life of bleach (6 months) and the hazardous nature of the solution make transporting, storing, and using bleach problematic. The Navy seeks to replace bottled-bleach with an on-site system that generates a concentrated disinfectant on-demand and preferably requires no consumables. This Phase I SBIR proposal describes the evaluation of three different disinfectants and their associated on-demand generation technologies as a replacement for bottled bleach. The three disinfectants, which are generated electrochemically, are potent, well-known germicides currently used for similar applications. During the Phase I research period, a comprehensive review of the scientific literature will determine what concentrations of these alternative disinfectants are required to match the performance of bleach in the field. This information will then be combined with the performance specifications of each of the electrochemical generation systems to determine the best technology to replace bottled bleach. The Phase I work will conclude with the fabrication and assembly of a breadboard disinfectant generation system.

Title:One-to-one Bleach Replacement with an Electrochemical Bleach Generator
Abstract:Deployed U.S. forces use bleach, a 5% solution of sodium hypochlorite, for water purification, surface sanitization, general cleaning as well as fresh fruit and vegetable processing. However, bleach is difficult to transport and has a short shelf life, making it is highly desirable to produce the disinfectant bleach on-site. The bleach production device needs to be capable of generating solutions with concentrations of bleach identical to those now used, enabling the continued use of military dilution tables and manuals concerning the use of bleach. Unfortunately there is currently no available equipment of a suitable size and cost that will produce a 5% bleach solution. TDA Research, Inc. (TDA) therefore proposes to develop a device that is capable of converting common table salt (NaCl) to sodium hypochlorite (NaClO) solution using only electricity. TDA’s device will not require additional chemicals that pose a safety, shelf life or shipping issue. This system will be simple to operate, requiring a minimum of training and operator involvement.

Abstract:The objective of the Phase 1 and 2 SBIR Topic N06-040, “Ultra-Wide Band Antenna (UWBA) For Electronic Attack Aircraft”, is to provide to the Navy innovative, new, and advanced techniques to increase the band coverage of the improved tactical Jamming Systems aboard the EA-6B and EA-18G aircraft (see figure 3-1), with very limited space. At the present time, the antennas used with the ALQ-99 do not provide all of the desired capability in one suite of antennas. The appropriate antennas must be selected to “missionize” each aircraft flight. The ALQ-99 JTS Pod (see figure 3-2) is to be populated with a full set of antennas to cover all bands of operation.

Title:On The Move (OTM) High Frequency (HF) Communications Capability for the EFV
Abstract:The EFV is a strong asset in the arsenal of the US Marines. One of the targeted efforts of the Marines is to improve the HF communications capability of the vehicle by upgrading the current fixed-base whip antenna to an antenna that supports a Near Vertical Incident Signal (NVIS) mode of operation. Point-to-point terrestrial communications at the HF Band (2-30 MHz) provides flexibility in link range unavailable at other bands. In order to support a NVIS mode, the peak-of-beam of the antenna must point towards zenith within approximately 10„a so that the transmitted signal reflects from one of several layers of the ionosphere. FIRST RF proposes two possible design solutions. The first approach utilizes a pair of configurable vertical monopoles. The second approach is a loop antenna. Omni-directional coverage On the Move (OTM) is achieved.

Title:Innovative Manufacturing Process for Defect free, Affordable, High Pressure, Thin Walled Hydraulic Tubing for Navy Aircraft
Abstract:The objective of the technical effort is to eventually identify a material and a process that produces thin wall high pressure tubing for high performance aircraft, specifically Navy aircraft. The need for improvements stems from disastrous failures and the subsequent failure investigations that have indicated a need for a more fracture-tolerant tubing material. The first phase of the effort will consist of four distinct activities: 1. Titanium Alloy, TI-425.will be evaluated as a replacement material for Ti-325, the alloy used in current high pressure hydraulic tubes. The former is a relatively new alloy, stronger than Ti-325, with good cold-working performance. This activity will use flat plates. The goal is to identify an oxygen level and thermal treatment that results in a condition such that the 425 alloy is still stronger (and more crack resistant) than the 325 alloy while, exhibiting superior ductility ( and thus, workability). 2. Manufacturing studies will be conducted with major Titanium suppliers to insure that the research results can be economically transferred to large-scale industrial practice 3. Systems-level studies will be held with a major aircraft manufacturer to determine the impact of the change in tubing material on systems performance. 4. Liasion will be established with laboratories involved in Pressure Impulse Testing

Title:Novel Alloys and Innovative Low Cost Manufacturing Process for Defect Free, Improved, High Pressure Titanium Hydraulic Tubing for Navy Aircraft
Abstract:This Phase I SBIR proposal addresses the Navy’s need to improve the reliability and safety of titanium thin-walled, high pressure hydraulic tubing used in naval aircraft. Powder metal processing will be used to produce novel, cold formable titanium alloys that are more damage resistant and damage tolerant than the standard tubing alloy, Ti-3Al- 2.5V. Tubing will be produced from P/M tube hollows and evaluated to establish the technical feasibility of using P/M tube hollows as starting stock to produce titanium hydraulic tubing. In Phase I several innovative titanium alloys will be evaluated for cold formability, damage resistance and damage tolerance by; smooth and notched tensile properties, scratch hardness, indentation hardness, microstructure and chemistry. These tests will identify the most promising alloys for the production of hydraulic tubing and establish the initial economic and technical viability of making tubing from P/M tube hollows. Impulse tests and low cycle fatigue testing of tubes will be conducted in the Phase I Option to establish that tubes produced from the alloys developed in Phase I are indeed superior to Ti-3Al-2.5V. The proposed technology will answer the need for affordable, damage resistant and damage tolerant titanium thin-walled high pressure hydraulic tubing for military and commercial aircraft.

Title:DRIFT ProcessThermoplastic Composites Materials & Innovative Manufacturing Process for Thin Wall, High Pressure Hydraulic Tubing for Navy Aircraft
Abstract:Great Lakes Composites will utilize its extensive background in thermoplastic composites materials to provide an innovative solution to develop a high pressure, thin-walled hydraulic tubing for Navy aircraft. GLC will utilize the patented Direct Re-Inforced Fiber Technology (DRIFT) process to heat fuse thermoplastic resin to continuous fibers, to efficiently and thoroughly impregnate the fibers without damage, improving the reliability and safety of hydraulic tubing. GLC anticipates that thermoplastic composites tape-form materials, wrapped to form the tubing, will exceed the Navy’s expectations, as well as significantly reduce failures. The additional benefits of cost and weight reduction, along with re-formability in the field will further contribute value-added benefits for both the Navy and potential commercial markets. The resulting properties of the thermoplastic composites materials tubing will include a minimum of 5000 psi, a continuous use temperature of greater than 400◦ F, an outside diameter of 0.25” to 0.75” with a wall thickness of 0.022” to 0.065” respectively, and a minimum of 10 feet to 30 feet or more in length. It is anticipated that the resulting thermoplastic composites materials tubing will have zero degradation of properties under continuous exposure to hot hydraulic fluids and be resistant to ‘chafing’ of the outer surface.

Title:NDE for Residual Stress Relaxation
Abstract:Fatigue lives of rotating engine components are greatly enhanced through application of shot peening and other processes that impart residual compressive stresses to their surfaces. X-ray diffraction measurements, however, confirm that these stresses relax during service. Furthermore, residual stresses may relax rapidly or gradually and can vary by location. This proposal addresses the need for a nondestructive method of measuring and tracking residual stress relaxation with scanning MWM-Arrays. JENTEK’s patented MWM-Arrays have demonstrated capability to measure shot peen quality in nickel alloys and we are confident we can transition a solution for stress relaxation tracking in nickel alloy components, within two years. This proposed program will also address stress relaxation in titanium alloys. JENTEK currently has two active programs that will provide leverage to this program. Under Air Force funding, we are adapting our technology for manufacturing quality assessment of Low Plasticity Burnishing and Laser Shock Processing. Under a separate Air Force program, we are adapting our technology for IBR inspection for cracks and mechanical damage. Scanning MWM-Arrays, already integrated into automated engine disk inspection systems in use at Navy depots, have the potential to provide crack detection and residual stress relaxation tracking with a single inspection.

Title:Residual Stress Measurements Program to Support Condition Based Maintenance (CBM) of Critical Rotating Components of Propulsion Systems
Abstract:Surface enhancement processes are extensively used to introduce compressive residual stresses (CRS) and enhance the fatigue performance in titanium and nickel alloy rotating components for Navy propulsion systems. CRS can relax in rotating components as a result of thermal exposure and cyclic stresses, adversely impacting the fatigue life and strength. Relaxation can occur rapidly depending upon the relative component temperatures and cyclic stresses. Inspection of the components is performed on a routine basis to characterize damage levels in accordance with Technical Manuals (TM). However, the CRS are currently not monitored and tracked during routine inspection. As part of the inspection cycle, components are re-shot peened to overcome any residual stress relaxation that may have occurred. Intervals at which the components are re- peened may or may not be appropriate for the rate of compressive relaxation. A portable XRD measurement device capable of quickly quantifying the CRS would allow the Navy to track the surface residual stress in support of condition based maintenance of critical components. The measurement device would allow for field measurement of critical features of blades and disk components. The device would be capable of not only measuring the surface residual stress but also the cold working which has a significant impact on the rate of relaxation.

Title:Residual Stress Measurements Program to Support Condition Based Maintenance (CBM) of Critical Rotating Components of Propulsion Systems
Abstract:The fatigue properties of metals used in modern turbine engines are improved by cold working processes, such as the various forms of peening. Peening imparts compressive residual stresses (RS), which inhibit, or prevent, the initiation and propagation of cracks in critical locations of turbine engine components. The problem is that the RS state of critical rotating components, whether peened or not, is seldom known. This is complicated by the fact that RS relaxes with operational usage; thus, later in the component’s life cycle it becomes possible for the RS to become tensile—a potentially dangerous condition for critical components. RS is a key factor that must be fully understood to ensure the requisite fatigue life. Currently, NAVAIR has no means of reliably and nondestructively measuring RS in the tight locations of critical rotating components. Proto has considerable experience in measuring RS in numerous components of several USAF engines, including the F-22 engine, and is recognized as the world’s leader in x-ray diffraction RS technology. Proto proposes to prove the feasibility and demonstrate its robust capability to perform RS measurements in the lab as well as the depot environment of FRC-SE. This proof-of-concept will be performed on a current fighter engine. Proto plans to develop and demonstrate a database management system, tailored for RS data, to archive, analyze and develop RS trends for input to fatigue life prediction. Proto further proposes to conduct laboratory testing and analyses to develop the RS/fatigue relationship for use in prognostics or life prediction in Phase II. The RS measuring capability proposed by Proto will contribute directly to Condition Based Maintenance by enabling direct measurements and supporting quantitative decision making in materiel disposition matters, such as to accept, rework or reject, for these high value engine components.

Title:Smart Sensor Hub for Corrosion Monitoring
Abstract:Corrosion of aircraft and rotorcraft is the single largest maintenance cost driver for the Navy and Marine Corps. In order to maximize aircraft availability and minimize inspection and maintenance demands, Luna proposes to develop a smart sensor hub to support corrosion monitoring of aircraft. The sensor hub will be the central application device for a complete corrosion monitoring system that detects early stages of corrosion and estimates corrosive severity. The smart sensor hub will perform wireless network communications, transducer communications, and data conversion and application functions. It will also provide power management to the transducer circuitry and energy scavenging devices to maximize service life. The system will have an open architecture and configurable interface with loading options to accommodate the widest possible range of sensors. Luna’s corrosion monitoring system will fuse diverse datasets for improved state awareness and reduced uncertainty in measuring corrosion damage and estimating useful life remaining. The Phase I program will conclude with a breadboard demonstration of the functional elements of the smart sensor hub including power management, control and communication, and data storage. Luna will also demonstrate corrosion sensor response to early stage corrosion damage of aircraft alloys

Title:Miniature Corrosion Sensor Hub to Monitor Difficult-to-Access Aircraft Structure with Complex Geometry.
Abstract:MSI specializes in design and commercialization of miniature intelligent low power instrumentation systems that process data from sensors in scripted Bayesian algorithms in a “rules engine” application. Recently MSI received a US patent a new monitoring methodology for difficult-to-access aircraft structure with complex geometry. Our product will incorporate a tiny processor and a power scavenger circuit in a tape that supports ribbonized sensitized fiber strands. The ribbonized sensitized strands will extend around, under, and on a structure such as a magnesium gearbox housing, a highly complex geometry casting up to 3 cu ft in size. Deterioration or damage to the ribbonized strands will indicate, probabilistically, that damage is occurring to the item under test. The sensor hub will incorporate a low power electronic circuit called the Embeddable Programmable Instrumentation Circuit (EPIC) which is designed for creating stand-alone low power monitoring systems for aircraft and ground vehicle CBM and PHM. The EPIC processor is very low power, capable of being powered by a energy scavenger circuit. The new module will support intermodule wireless communication, and provide interrogation and wireless offload of the state of health of the equipment being monitored to the inspector’s handheld or PC.

Title:Miniature Corrosion Sensor Hub to Monitor Difficult-to-Access Aircraft Structure with Complex Geometry.
Abstract:Embedded wireless sensors for corrosion monitoring of critical aircraft components are needed for improved condition based maintenance and future structural health monitoring (SHM) systems. The objective of this Phase I SBIR proposal is to design, develop, and test a corrosion measurement and data collection system that can utilize multiple types of corrosion sensors. A key design criterion is that the system be extremely low power which will enable its use with energy scavenging power sources, such as vibration based energy harvesters. The basic architecture incorporates a hub which manages data collection and storage from multiple distributed remote corrosions sensing nodes (CSN’s). Communication between the hub and the CSN’s is achieved using a micro power variation of the RS-485 bus architecture, which allows for up to 256 distributed nodes. The hub incorporates high density non-volatile flash memory for data storage and utilizes an IEEE802.15.4 radio link for offloading the collected data to a remote handheld or personal computer. The CSN’s can employ any type or corrosion sensing method, including resistive, electrochemical impedance spectroscopic (EIS), and inductive techniques. Future distributed nodes could be developed that support various other structural sensors, including strain, pressure, and vibration sensors.

Title:3D Optical Defectoscope System
Abstract:To address the Navy need for a cost-effective nondestructive evaluation system to facilitate high rate, high-precision inspection of hybrid ceramic bearings, Physical Optics Corporation (POC) proposes to develop a new 3D Optical Defectoscope (3DOD) system based on shearing of scattered light from defects of ceramic elements. The 3DOD performs precision 3D mapping of surface and subsurface defects in ceramic elements at a high operation rate. Innovative implementation of shearography, polarization control, and new optical design, all of these make 3DOD applicable for inspection of ceramic surface features. Implementation of shearography, which is a proven NDE method, offers robustness against environmental disturbances, optical alignment, and high sensitivity to detect defects with a resolution of 0.2 microns. The 3D defect measurement provides high detection probability, with very low false negative and false positive rates. The 3DOD design includes fiber optic bundles and a universal handling module that makes it applicable for both rolling and ball ceramic elements. In Phase I POC will demonstrate the feasibility of the 3DOD prototype by 3D defect mapping for ceramic rolling elements. In Phase II, POC plans to develop an automated prototype for inspection of ceramic ball bearings.

Under the proposed effort, an NDE capability will be developed and demonstrated that can quickly and cost effectively detect various types of manufacturing defects found in ceramic rolling elements used in hybrid bearings including surface and bulk flaws. The NDE capability will be adapted from the Process Compensated Resonance Testing (PCRT) technology currently used for metal and ceramic parts in the automotive and aerospace industries. PCRT uses Resonant Ultrasound Spectroscopy (RUS) coupled with genetic sorting algorithms and the Mahalanobis-Taguchi statistical method. PCRT is able to determine patterns within the resonant spectra of acceptable and unacceptable parts. These patterns will then be used to generate a sorting tool that can consistently separate parts with any combination of acceptable variations from those with a single occurrence of an unacceptable variation, i.e. critical flaw.

Title:A Lightweight, In-Situ Corrosion Sensing Module (CorrSeM)
Abstract:Impact Technologies, in cooperation with The Boeing Company and IMR Test Labs, proposes to develop a low power, lightweight, miniature sensing device capable of sensing parameters which contribute to corrosion development in aircraft structures and components. By monitoring the primary drivers of corrosion as opposed to only its formation and effects, maintainers will be able to more proactively address corrosion within a more prognostic condition-based maintenance framework. The Phase I program objective is to demonstrate a prototype Corrosion Sensing Module (CorrSeM) for monitoring environmental factors contributing to corrosion development. Impact will leverage its experience in developing in-situ embedded sensing solutions to architect, design, and build a prototype system for laboratory data collection and demonstration of Phase I feasibility. The ability of the prototype to track corrosion drivers will be verified through controlled ISO and ASTM test methods. At the end of Phase I, Impact will create a development plan leading towards inexpensive, lightweight, miniature solutions which meet or exceed performance expectations. Successful completion of Phase I objectives will allow for smooth transition into a Phase II program focused on rigorous testing of the CorrSeM’s capabilities under both laboratory and real-world scenarios and the development of miniature CorrSeM prototypes.

Abstract:Corrosion of aircraft and rotorcraft is the single largest maintenance cost driver for the Navy and Marine Corps. In order to maximize aircraft availability and minimize inspection and maintenance demands, Luna proposes to develop a miniature, light weight sensor suite that will measure corrosive severity of aircraft operational environments. The smart corrosivity sensor suite will monitor multiple environmental parameters and quantify cumulative corrosive effects that an aircraft experiences. The light weight and small size of the self contained sensor suite will permit instrumentation of critical components and “corrosion hotspots” within the aircraft. The sensor suite will be designed as a smart transducer interface module for compatibility with a network capable application processor such as the miniature corrosion sensor hub (Topic NAVY 07-169). The sensor suite will be a low power device for long life use with a battery or energy scavenging module (Topic NAVY 07-178). Luna’s environmental corrosivity sensor suite will fuse measurements of environmental parameters and corrosivity for improved state awareness and reduced uncertainty in estimating coating system breakdown and structural material damage. The Phase I effort will be concluded by demonstrating the correlation of the breadboard prototype sensor suite response with corrosion of aircraft alloys in accelerated environmental corrosion tests.

Abstract:To address the Navy’s need for an environmental sensor suite to monitor corrosion- influencing parameters for aircraft structural materials, Physical Optics Corporation (POC) proposes to develop a new Miniaturized Fiber-Optic Spectroscopic (Mini-FOS) Corrosion Sensor system. This system is based on fusion of several environmental and chemical sensors innovatively integrated on a single optic fiber for monitoring all relevant parameters simultaneously. The self-contained system will be compact (<1 ounce, <1 cubic inch) and powered by an energy scavenging circuit to generate 1 mW/cc. With a detection sensitivity of parts-per-billion for chemicals, ~0.01 degrees C for temperatures, and 0.01% for humidity, this system will collect and store data at a rate of at least one Hertz during flight. In Phase I POC will demonstrate the feasibility of Mini-FOS by investigating the system design by computer modeling, and fabricating and testing a breadboard prototype (TRL 4) in a simulated corrosive environment. In Phase II an advanced, miniaturized Mini-FOS engineering prototype with TRL 5 will be assembled and tested both at POC and at a Navy facility.

Abstract:Arizona Paradrogue Systems, a drogue coupling assembly, a drogue coupling assembly development and manufacturing firm and SySense, Inc, systems development firm specializing in navigation and control design for autonomous air refueling systems have teamed together to develop a fully stabilized and controllable drogue. APS and SySense plan to generate an analytical model of a stabilized/controllable drogue through numerical analysis simulating tanker, receiver and drogue bodies in turbulent air as well as navigation and electro-optical devices as sensors to provide control and feedback information to actuators installed on the drogue. The design will be based on existing APS drogue designs and will bolt on to existing drogue refueling systems requiring no additional mechanical modifications to the hose/reel system. Phase I investigation shall focus on using the C-130 high speed basket as the model in order to demonstrate the concept. Transverse force data on the drogue shall be obtained through wind tunnel testing using a basket modified with manual devices to simulate canopy manipulation. This data shall then be combined with sensor and navigation data to complete the analysis. The Phase I option shall expand the analysis to include C-130 Low Speed basket, Buddy Store and Variable Speed Drive. A full scale prototype will be constructed to demonstrate the concept in the Option phase.

Abstract:Nielsen Engineering & Research (NEAR) is proposing to develop an innovative controllable drogue system based on their CDC7 technology. During the Phase I effort, a second generation CDC7 design, which meets the Navy's specific needs, will be developed through numerical analysis and full-scale wind tunnel testing. System feasibility will be demonstrated through dynamic simulations that include the tanker, hose, controllable drogue, sensors, receiver, and atmospheric turbulence. These analyses will demonstrate that NEAR's controllable drogue system can maintain the refueling basket at a specified stabilized location relative to the tanker even in severe atmospheric conditions. In addition to this aerodynamic performance, the proposed drogue system is reliable, durable (minimizing FOD potential), lightweight, compatible with existing USN/USAF refueling systems, and requires no receiver modifications. While the proposed work plan is very ambitious, it is made achievable through the use of 1) NEAR's existing refueling technology and numerical modeling capabilities, 2) a development team with significant experience in the field of aerial refueling, and 3) external funding from a commercialization partner that is established in the aerial refueling industry. The Phase I program will provide a strong foundation for subsequent development and flight testing of the controllable drogue in the Phase II contract.

Title:Practical Assessment of Noise/Performance Trade for High NPR Nozzles
Abstract:With improvements in high performance military jet aircraft engines and the increase in complexity of the exhaust systems the noise produced has become problematic. Reducing these noise levels, while maintaining overall system performance, has become the driving issue in new nozzle designs. This proposal will focus on nozzle designs of practical application that can be implemented on current high NPR engine configurations, such as chevrons (or serrations) cut into the trailing edge of the nozzle. In Phase I we will address the practical aspects of making the noise/performance tradeoff for high pressure ratio nozzles. Data will be collected on models in a subscale test facility and evaluated using near field holography and shadowgraph imagery to identify the source characteristics. This will aid development of both CFD and noise prediction algorithms in Phase II.

Title:Exhaust Jet Noise Reduction for Tactical Aircraft
Abstract:A class of high amplitude and high bandwidth actuators called localized arc filament plasma actuators (LAFPAs) have recently been developed at OSU and used for control of high-speed and high Reynolds number jets. The control included successful noise mitigation in a Mach 0.9 jet and mixing enhancement (and very preliminary results for noise mitigation) in a Mach 1.3 ideally expanded jet. The control relies on high bandwidth of the actuators and excites various instabilities in the jet to achieve the goal of mixing enhancement or noise mitigation. The proposed Phase I work will explore the effectiveness of this technology in more practical supersonic exhaust jets operating with various flow regimes (i.e. ideally-, over-, and under-expanded) and high temperature. Phase I work will pave the way for detailed parametric study of the control issues to achieve maximum noise mitigation in Phase II, where we will also explore integration and commercialization issues.

Title:Exhaust Jet Noise Reduction for Tactical Aircraft
Abstract:The absence of a comprehensive, integrated aerodynamic/aero-acoustic modeling and analysis framework represents an impediment to achieving significant noise reduction within constraints imposed by the engine cycle, realistic geometry, and airframe. We close the gap by developing a suite of advanced, high fidelity nozzle performance and jet noise-based tools integrated into a unified software package with validation cases and applicability assessments. The flow field software will be based on TTC Technologies, Inc. multi-disciplinary high-order CFD tool, AEROFLO, which predicts temporal and spatial flow fields at all speeds (subsonic, transonic, supersonic, and hypersonic). The tools, ranging from RANS to LES, will be installed as modules interfaced with a comprehensive set of aeroacoustic source modules populated with fundamental physics-based aeroacoustic and semi-empirical models, to allow a range of prediction methods via “pull- down” menus. A large-scale noise model based on a RANS/PSE approach developed by UTRC and Caltech will also be implemented. The simulation codes will be rigorously validated using UTRC acquired data with limitations documented in terms of accuracy, robustness, sensitivity, turnaround time plus recommendations for improvements. The tool will provide a comprehensive approach to the design and development of nozzle components that attenuate exhaust jet noise.

Title:Hand-held Corrosion Scanner/Imager
Abstract:As a result of the environment in which they operate, Naval aircraft are subject to pervasive corrosion damage. On-board sensors can signal when corrosion may be occurring, but there is a need for a portable corrosion scanning system that can confirm the degree and location of actual corrosion damage. JENTEK’s patented Meandering Winding Magnetometer sensors and arrays (MWM-Array) have proven capabilities for detecting and imaging corrosion damage on complex aircraft components, such as gear box housings and fuselage lap joints. They are thin and flexible, can be customized to suit the component and will conform to curved parts and areas with varying curvature. JENTEK has recently completed a NAVAIR funded Phase II program (Field Portable System for Electromagnetic Imaging of Cracks Under Fasteners ) that succeeded in integrating the functionality of the laptop computer into the impedance instrument and reducing the overall system weight from 28 pounds to 12 pounds. This proposed program will continue the design evolution to meet the Phase I goals of system volume less than 0.5 cubic feet and system weight under 10 pounds. Additionally, MWM- Arrays will be adapted to provide corrosion detection and imaging on specific components of interest to NAVAIR.

Title:A Portable Corrosion Detector for inspecting Aircraft Structures with Complex Geometries.
Abstract:Aging aircraft commonly suffers from several types of degradation including corrosion, cracking and lack of bonding. Severe corrosive environment of naval aircrafts results in corrosion as the fundamental reason for aging aircraft. A corrosion detection system, independent from geometrical complexities, needs to be developed to detect active corrosion. AE method can be used to detect corrosion growth on-line for periodically active corrosion or off-line for active corrosion during measurement. In this proposal, we propose to develop a hand-held detector using of state-of-the-art AE method to detect active corrosion growing on naval aircraft components. During the Phase I and Phase I Option periods of this project, we will demonstrate the feasibility of developing an AE system with optimized settings to detect active corrosion growing on naval aircraft components. The system will have a grading system as a part of analysis software.

Title:Portable 3D Corrosion Detector for inspecting Aircraft Structures with Complex Geometries.
Abstract:Photon-X is pleased to propose the next generation of corrosion detection devices to assist the Navy achieve its goal of reducing the impact of corrosion of aircraft maintenance cost. Our technology is an innovative integration of Spatial Phase Imaging (SPI) applied to both high-resolution video imaging and Terahertz (THz) imaging that captures full 3D volumetric analytical information of both surface and subsurface corrosion. The proposed detector is highly sensitive to submicron size defects such as corrosion in early stages much more effectively than any current technology. It will also provide quantitative volumetric data of corrosion location and severity. Each of the two technologies has been developed for other applications and has been proven to be very strong technology. We will measure the complex 3D geometries of the part and the small deformations that will occur on the surface and under layers of paint at the submicron level on the part. The system can be developed into a portable cost effective method to detect corrosion in critical parts before catastrophic failure. This proposed effort will determine the feasibility of integrating these technologies and establish a small handheld cost efficient corrosion detector and determine a path forward towards a Phase II effort.

Abstract:The implementation of intelligent propulsion concepts for the next generation of advanced propulsion systems requires development of advanced enabling technologies such as smart sensors, which are capable of intelligently using all of the available sensors for the synthesis of robust control strategies and the automated management of the health of the engine in order to complete a given mission. The proposed Intelligent Sensor Node (ISN) is a high temperature capable, modular design with the capability to interface with and manage multiple engine control sensors for pressure, temperature and other parameters, and communicate with the FADEC. The ISN can be reconfigured for interfacing with different classes of control sensors without hardware changes, and contains all of the circuitry needed for signal conditioning, acquisition, digital calibration and compensation. The ISN is an enabling building block for the realization of distributed FADEC control system architectures, and is equally applicable to hybrid or legacy FADEC system applications.

Title:Intelligent and Robust Sensor Network for Distributed Engine Control
Abstract:The Full Authority Digital Electronic Control (FADEC) centralized architecture has become the norm in aero-engine control systems. This architecture, which limits the design choices, accounts for ~20% of total weight and acquisition cost of the engine. Any modification to the system hardware is costly and inefficient. The limitations of electronics in high-temperature environments is another major issue. Distributed control architectures together with enabling high-temperature sensors and standardized interfaces will be able to provide a future-proof platform for next-generation systems. Photonics technology, including standardized fiber-optic wavelength division multiplexing (WDM), is becoming increasingly prevalent in many commercial systems including aircraft. Many systems, including avionics, now use 10-gigabit fiber-optic Ethernet. Also in use in aircraft systems are Fiber Channel and Firewire. IFOS proposes to address the problem with the development of a fiber-optic communications and control architecture based on Dense WDM (DWDM) and providing standardized optical network interfaces on a highly-reliable bi-directional optical network. In Phase I, IFOS will (1) develop a backbone architecture design concept appropriate for aero-engine control systems supporting many sensors with standardized interfaces, including IFOS’ high-temperature multiplexed sensors, and demonstrate its feasibility through performance calculations and simulations, (2) ensure the system design meets all requirements for engine control systems

Abstract:This program seeks to develop and optimize laser textured wear resistant coatings with adaptive solid film lubricants to protect and extend the life of aircraft engine components. Patterns of micron-sized dimples on surfaces act as reservoirs for smart, nanostructured solid film lubricants that adjust tribological surface properties in response to changing conditions to minimize wear. Optimization of the dimple depth, diameter, and pattern is necessary to obtain best performance from the adaptive lubricant. This program will determine that optimization for a variety of substrate metal and coating combinations of interest to DoD prime contractors. Best results from testing on coupons will be applied to realistic parts in an Option task. Based on Phase I results, projections will be made for processing costs and times in a production environment and estimates will be made of life cycle cost savings for target aircraft engine components. This program is a collaboration between a company with core expertise in laser ablation and surface texturing (MLPC) and a company with expertise in wear resistant coating deposition, solid film lubricants, and wear testing (TXI), with cognizance and input from a Prime Contractor (Rolls-Royce) that will provide an early commercialization transition opportunity for successful program outcomes.

Title:Micromechanical Models for Dielectric Behavior of Ceramic Matrix Composites
Abstract:The proposed program will enhance material and sensor models to provide improved understanding of dielectric property information regarding Ceramic Matrix Composite (CMC) material condition. These models are to be used to assess thermochemical degradation of CMC’s and also to assess the condition of materials during manufacture. JENTEK has developed a family of electroquasistatic and magnetoquasistatic sensors and arrays that have successfully solved a wide range of previously intractable NDE problems. These sensors and sensor arrays use model-based inverse methods to estimate electromagnetic properties that are correlated with many conditions of interest, such as thermal degradation of component materials. JENTEK’s Interdigitated Electrode Dielectrometer is being adapted for manufacturing quality control of CMC’s. The goals of this Phase I program are to extend standard micromechanical models to predict dielectric behavior of coated fiber CMC’s, to incorporate these models into anisotropic layered material representations for dielectric sensor models, and to relate composite constituent behavior with thermal exposure conditions. To address this need, we will work with CMC thermostructural modelers (MR&D), manufacturers (COI Ceramics), and an end user (Pratt & Whitney). In Phase II, we will refine the models to support in-service material evaluation and self-consistent prediction of dielectric, thermochemical, and structural behavior.

Title:Micromechanical Assessment of Thermochemically Induced NDE Changes in Advanced Composites
Abstract:The Joint Strike Fighter is considering the use of organic and ceramic matrix composites for high temperature engine components. Material coupons and flight tests have shown that when these materials are exposed to high temperatures in the presence of air, salt fog, and humidity they can react chemically. The chemical reactions may cause a significant loss in composite strength even though there is no physical evidence of damage. Standard non destructive evaluation techniques such as ultrasonics, radiography, and thermography have not been able to accurately identify and monitor the chemical changes. Fortunately emerging NDE techniques based on electrical resistivity, electromagnetics, and dielectric properties have shown promise in relating chemical changes to NDE signal. These techniques, however, are in their infancy and the measurements are sensitive to sensor design, scanning technique, and data interpretation. In order to develop the electromagnetic-based NDE methods into useful engineering tools, it is necessary to understand the theoretical dielectric properties of advanced composites. The development of a micromechanical model for composite dielectric properties will support the development of NDE techniques and standards that can monitor chemically induced changes in advanced composite engine components. Materials Research & Design proposes to build upon their demonstrated understanding of composite material theory and develop a micromechanical model that relates composite dielectric behavior to constituent properties, fiber volume fraction, and fiber orientation. The theory will be tested for feasibility by comparison to NDE signals measured on CMCs of interest. The program will be undertaken by a team of MR&D and Jentek Sensors, Inc. MR&D will develop the theory, debug the computer code, procure CMC specimens, define the test plan, correlate the data, and prepare the reports. Jentek, as a subcontractor to MR&D, will consult on the theoretical assumptions, measure the NDE response, and reduce the raw data.

Title:Development of a Miniature, Vibro-Mechanical Energy Harvester for Powering Wireless Sensors
Abstract:In the proposed work, we will develop a highly efficient and miniaturized vibration energy harvesting device suitable for use on drive system components of helicopters. The goal is to provide power to run a wireless corrosion hub and sensors (to be developed simultaneously in a separate program). The target power generating capability is 5mW under vibration conditions typical of steady state flight. The size and mass of the system will be miniaturized. Target metrics are 0.0.1mW/gram, and 0.5mW/cc. The harvester will be implemented using our proven strain optimized, resonating cantilever beam with Macro Fiber Composite piezoelectric elements. An integral energy harvesting circuit will be based on one of our two proven circuit designs, our Managed Switching design, or out Capacitive Discharge design. The principle technical challenges will be in minimizing the size and mass of the device while still achieving target power output. This will be achieved by stacking multiple layers of MFC material on the beam, and implementing design features to minimize the beam’s stiffness. Ensuring long term reliable operation in hostile environments is a second technical challenge. We will accomplish this through careful selection of materials, and by incorporating environmental sealing and overload stops into the enclosure design.

Title:XMR- A Novel Vibration Harvesting System for Wireless Sensors
Abstract:Wireless sensors promise to reduce the Navy’s aircraft maintenance costs via real-time monitoring of corrosion-prone components. The promise of wireless sensors lies in their reduced susceptibility to failure, reduced weight and configurational flexibility compared with conventional wired sensors. However, because of the costs of replacing batteries in sensors deployed in inaccessible locations, a significant challenge for wireless sensors is power. In this Phase I effort, TPL proposes to develop a vibration harvesting power system comprising a new vibration harvesting module developed at Washington State University and TPL’s patent-pending power management and storage system. The new harvester design is highly efficient, tunable over a broad frequency range (several 10s Hz), relatively inexpensive to manufacture, and is no larger than a stack of 3 US quarters. TPL’s power management system efficiently stores the harvested energy in electrochemical energy storage devices to efficiently meet steady state and pulse power loads (up to 500mW) as well as provide back-up power in the absence of harvestable vibrations. Designed for “ZigBee”-type applications, this system can be customized for any user-specified profile. Successful completion of the proposed effort will pave the way for a unique solution to providing power for the Navy’s remote, wireless systems.

Abstract:The lowered cost of maintenance, lowered weight, and reduced installation complexity of smart electric actuators continues to justify the transition from hydraulic actuation to EMAs/EHAs. This SBIR proposal will extend the advantages of EMA technology into high- temperature, high-vibration applications with a first commercialization target being the JSF F35 Lightning II aircraft platform. During the SBIR Phases I research, PCKA will collaborate with NAVAIR and Lockheed Martin to establish the actuator requirements. Once the requirements are defined, PCKA will identify suitable actuator architectures for the application and then optimize the design in terms of weight, reliability, maintainability, manufacturability, and cost. Key design constraints will be the thermal and vibration environment which may necessitate the use of specific motor technologies, high- temperature wire insulation, lubrication, and electronics. In Phase II, PCKA will fabricate a prototype of the optimal design and perform qualification tests including EMI/EMC, vibration, shock, and altitude. If successful, developed technologies will ultimately transition to DoD programs under a Phase III contract.

Abstract:In this Phase I effort Pharad will investigate a new antenna structure that can be stealthily integrated or mounted on the surface of an Unmanned Aerial System (UAS) platform and is capable of operating efficiently over a wide band of frequencies; from L-band to Ku- band (1 – 18 GHz). Importantly, the new printed antenna will have minimal radiation pattern variation or gain undulation across this entire frequency band.

Abstract:The objective of the proposed research program is twofold. Spectra Research will demonstrate new computational tools and design methodologies for optimizing antenna performance of electrically small antennas and antenna arrays. In addition, Spectra Research will show advanced antenna constructs that incorporate metamaterials to reduce EMI, coupling, profile/size, and to increase radiation efficiency in broadband communication antennas mounted on advanced composite platforms. The proliferation of antenna systems on the modern airborne platforms (such as the N-UCAS) that utilize advanced planar composite technology places great demand on the development of tools and technologies for the design and integration of small communication antennas and broadband antenna arrays. Incorporating additional antennas into the platform often causes an issue with parasitic coupling and electromagnetic interference (EMI) between radiating or receiving structures. As a consequence, new antenna concepts that provide for multiple functions in a common aperture must be explored and perfected. Advanced antenna design tools and techniques must accurately simulate the antenna structure and optimize the antenna performance, while exploiting the advantages of a complicated electromagnetic environment that may include custom materials (ie. electronic bandgap (EBG) structures) as well as artificial dielectrics and magnetics.

Abstract:To meet the need of the Navy in fabrication and measurement of conformal windows such as toroidal to precise optical tolerances from ceramic materials, Applied Science Innovations (ASI) proposes development of the Closed-Loop Fabrication of Free-Form Optics (CLF3O), building directly on ASI’s successful development of a new tool for metrology on conformal aspheric domes and corrector optics. The proposed CLF3O system is a modular attachment for integrating a standard commercial interferometer with an existing optical fabrication tool. Proposed measurement and processing will ensure precise determination of location and orientation of the window being fabricated and tested, in addition to measurement of the optical figure of both surfaces. The proposed CLF3O attachment will enable one iterative procedure of fabrication and measurement, in which the part will remain in place until finished to specification. Phase I will focus on the optomechanical design of the modular attachment for integration with both a fabrication machine and a standard interferometer, and on application-specific processing algorithms. In Phase II, the tool will be installed in one of the manufacturing facilities to produce a window with the shape selected in agreement with the Government and the dimensions on the order of 200 x 200 mm.

Title:Conformal Sensor Window
Abstract:Conformal sensor windows offer advantages over axisymmetric surfaces in the ability to reduce drag and weight. Materials of interest include spinel, polycrystal alumina, and ALON. However, the description, fabrication and metrology of these surfaces can be costly, or even impossible. Fabrication of these surfaces is difficult, since they are not axisymmetric and can have varying local radii of curvature, rendering grinding, lapping and polishing of these surfaces untenable. A method to overcome these difficulties in fabrication is to apply ductile mode machining (DMM) to eliminate grinding, lapping and polishing. DMM has been successfully applied to SiC mirror and Infrasil 302 glass transmission surfaces to achieve the requisite surface finish and figure error for axis- symmetric optics. Through the use of physics-based modeling, DMM conditions can be identified where material removal results in ductile chip formation, damage free surfaces and excellent surface finish. This SBIR activity extends the technology of DMM to torroidal configurations enabled by physics-based modeling technology. We will further develop and enhance its modeling capability for application to spinel workpieces. In Phase I we will demonstrate the feasibility of DMM to machine a spinel torroidal window in a laboratory environment with Breault performing the requisite metrology.

Title:Conformal Sensor Window
Abstract:Freeform optics allow for greater versatility in optical design that will give the designer the ability to decrease the number of optics in an assembly lowering the amount of mass and volume required to attain the same optical properties. Currently the design and fabrication of freeform optics are costly due to the difficulties introduced with mainly the fabrication and metrology of these parts. By giving the designer realistic constraints as to what can be fabricated along with continued improvements in fabrication methods, large improvements can be gained in the properties of optical assemblies mainly due to the mass and volume advantages that are provided by the use of freeform optics. OptiPro has a unique opportunity for combining its newly developed solution for the Navy’s ogive SBIR metrology program, to it’s extensive knowledge of CAD/CAM and, “freeform capable” computer numerically controlled precision optical grinding and polishing products. OptiPro’s technologically advanced optical manufacturing capabilities along with a “support partnership” with the Penn State University Electro Optics Center in the area of finishing materials and processes, gives us a very strong team and, clear path towards solving the difficult problems associated with, grinding, finishing and measuring of Conformal optics.

Title:Aerodynamic Infrared Dome
Abstract:Infrared domes currently have a hemispheric shape because this shape introduces minimal optical distortion and is easy to fabricate. Future high-speed missiles require aerodynamic infrared dome shapes that reduce drag and have greater ability to withstand aerothermal heating. Several Navy SBIR topics have addressed fundamental issues of fabricating a subscale ogive shape from infrared-transparent polycrystalline alumina and developing methods to grind and polish the outer and inner surfaces to the intended shape. To this point, aerodynamic domes meeting optical tolerances have not been produced. The Navy desires to advance the technology and lower the cost for making ogive infrared domes by expanding the candidate midwave infrared materials to include ALON and spinel and by investigating alternate grinding and polishing approaches. Surmet proposes herein to leverage work performed under internal funding as well as on previous SBIR contracts to address these issues. Specifically, under the Phase I contract Surmet proposes to 1) demonstrate the ability to apply green machining techniques to form near-net shape ALON (and in phase II, spinel) ogive dome blanks and 2) identify, perform initial demonstrations, and downselect novel optical finishing techniques for final finishing of ogive domes using the various technical capabilities of Surmet Corporation.

Title:Advanced Low Temperature Ionic Liquids for Naval Electrochemical Devices
Abstract:The development of improved performance supercapacitors, batteries, electrochromic devices, sensors, and other electrochemical devices is critical to meet the current and future needs of Naval Air Systems. The ability of electrochemical devices to operate over extreme temperature limits (-70 to +100 degrees Celsius) is essential to tactical aircraft, strike weapons, and other systems, which can encounter sub-freezing temperatures during operation. The performance of current electrochemical devices is particularly limited at low temperatures by the low conductivities and high viscosities of current organic solvent-based electrolytes. Ionic liquids offer improved safety and higher voltage windows than current electrolytes, however specific ionic liquids that permit adequate low temperature (sub-zero Celsius) operation have not been developed. During the Phase I project, Lynntech will develop low temperature ionic liquid systems with high conductivities, low viscosities, high voltage windows, and chemical and electrochemical stability with electroactive polymers. The Phase I project will optimize the electrolyte composition, determine the ionic liquids’ physical and electrochemical properties from -70 C to +100 degrees Celsius, and evaluate the electrolyte’s performance in electroactive polymer-based supercapacitors. During Phase II, Lynntech will optimize and scale up the process and demonstrate the ionic liquid’s performance in prototype devices.

Title:High Conductivity Low Temperature Ionic Liquids
Abstract:Physical Sciences Incorporated (PSI) proposes to develop, characterize, and evaluate new ionic liquids (ILs) and eutectics with enhanced physical and chemical properties for electrochemical supercapacitor applications. The ILs will be synthesized with high yield and high chemical purity as confirmed by standard analytical techniques. Results from differential scanning calorimetry, viscosity, ionic conductivity, and cyclic voltammetry experiments will validate that these ILs/eutectics can function effectively as electrolytes over a broad temperature range (±70 deg C) and large electrochemical window (±2V). The most promising electrolyte will be studied in an electrochemical system as a proof-of- concept. In Phase II, we will continue to develop and characterize innovative ILs and eutectic formulations. The new materials will have reduced viscosity, and an enhanced thermal stability, ionic conductivity, and electrochemical window compared to those studied in Phase I. Performance of the ILs/eutectics will be assessed in multiple electrochemical systems such as batteries, supercapacitors, and electrochromics. By the completion of Phase II, we will demonstrate ~ 10^3 reversible cycles of an electrochemical device using an IL/eutectic electrolyte at -70 deg C. Cost analysis and design specifications will be performed for limited rate production of several candidate materials.

Abstract:Small antennas are required to support surveillance sensors, communication links, navigation systems, command and control systems, and precision strike capabilities on Unmanned Combat Aerial Vehicle (UCAV) .Research advancements in meta-materials show promise in the design of high efficiency small antennas. Under this project, Applied EM is proposing to develop electrically small antenna designs using degenerate band edge (DBE) and magnetic photonic crystal (MPC) configurations. Extensive simulation studies will be conducted to design DBE antenna prototype achieving Chu-Harrington limit. Loading effects of lumped or distributed capacitive/inductive elements on DBE elements will be considered to overcome the fundamental gain bandwidth product limit. Multi-arm transmission line coupled DBE antenna will be also investigated to design antennas that can be structurally integrated within the UCAV.

Title:Design and Manufacture of a Structurally Integrated Metamaterial Antenna (1000-086)
Abstract:SI2 proposes to develop an electrically small metamaterial antenna with an increased efficiency/bandwidth product that is capable of being structurally integrated using N- UCAS advanced composite materials and SI2’s manufacturing technologies. The proposed concept utilizes several novel metamaterial miniaturization technologies and leverages SI2’s proprietary conformal electronics manufacturing technology to integrate the metamaterial antenna system with the structure. Both the metamaterial and manufacturing innovations will enable an electrically small antenna system with an increased performance to size and weight ratio. To help ensure applicability of our efforts, and to begin work towards technology transition, SI2 has teamed with a prime contractor who will provide system requirements and implementation opportunities. The Phase I program will demonstrate the electromagnetic (EM) performance of the metamaterial antenna through state of the art modeling and simulation. The manufacturability and ability to integrate the metamaterial antenna with a composite structure will be established through the design and manufacture of a hardware demonstrator. The follow-on Phase II program will refine the concept and develop a functional structurally integrated metamaterial antenna prototype. Testing of the prototype will validate the simulation and the metamaterial antenna’s improved radiation efficiency/bandwidth product compared to a conventional antenna.

Title:Metamaterial-Based Electrically Small Antenna
Abstract:Spectra Research proposes an innovative approach that employs advances in numerical modeling, fragmented aperture antenna design methodologies, and metamaterials research toward the development of an advanced electrically small antenna. In the Phase I program Spectra Research will investigate the development of electrically small antennas that demonstrate improved radiation efficiency over broad bandwidths. Antenna topologies will be selected that are compatible with employment on advanced composite platforms. Innovative approaches that improve overall antenna performance while minimizing antenna profile are desired solutions for all volumetrically restricted platforms. Both Cartesian and cylindrical FDTD simulations will be employed to provide a set of design rules that then may be used to modify analytical approximations. The technical objectives of the Phase I program are to demonstrate that fragmented aperture and fragmented volume antenna designs with metamaterial augmentation can be utilized to great advantage in meeting the requirements of the solicitation. Specifically the research team will utilize our advanced antenna technologies in concert with unique metamaterial approaches to produce a common aperture antenna architecture that has broadband utility, and demonstrates superior performance over selected frequency ranges.

Title:Static Analysis Tool for Interface Compliance Verification and Program Comprehension
Abstract:Our objective is to develop a static analysis tool that can be used by both software developers and verification specialists to verify compliance with standard interface specifications. As an additional capability, our tool will provide both developers and verification specialists with a robust interactive query-driven program comprehension capability that will significantly reduce the overhead of manual code review. While our tool will be applicable to any large C or C++ code base, we will specifically address issues relevant to the analysis of code developed to the Software Component Architecture (SCA). Our Phase I effort will demonstrate the feasibility of our approach by developing an initial prototype. Particular points of emphasis in our Phase I prototype will be to demonstrate the flexibility and extensibility of our approach. In Phase II we will produce an advanced prototype applicable to third-party applications. The transition target for this system is the JTRS Testing & Evaluation Lab (JTEL) which maintains test capability and certifies code in support of the Joint Tactical Radio System (JTRS) initiative. We will be aided in developing a more robust commercial product and in identifying additional transition opportunities though our collaboration with Mercury Computer Systems who are supporting our proposal.

Title:Algorithm Development for Standard Interface Compliance Verification
Abstract:This SBIR will implement the Software Analysis of Interface compLiance (SAIL) automatic interface test tool, which will support analysis of software interface implementations relative to a ‘Reference Interface’. The Reference Interface (RI) consists of a compilable (i.e. source code) definition of the interface standard, and is supported by a Reference Test Definition (RTD) which defines the functional test sequences to be applied to the RI. The SAIL software tool will verify multiple aspects of Interface Compliance: (1) Semantic Compliance, consisting of verification of compliance with the published interface standard (Reference Interface), and examination of the interface for extensions or sub- setting; and (2) Functional Compliance consisting of verification of basic functionality of functions or methods defined in the interface, and verification of error handling. SAIL will perform compliance testing relative to the Reference Interface while providing the user to extend and/or control tool perform through the following mechanisms: (1) User definition of standard interface (Reference Interface), (2) User definition of functional performance requirements, and (3) Plug-in extensions to the functionality verification portion of the tool.

Title:High Temperature Superconductor Circuit Integration with CMOS Electronics on Sapphire
Abstract:Various DoD systems are starting to incorporate superconducting devices for sensing and/or manipulating electromagnetic fields, from filters for shipboard communication systems, to superconducting transmission lines for use as a microwave power limiters, to the development of electrically small antennas. With the breakthroughs in the materials and fabrication technologies, it thus becomes feasible to design a system on sapphire with multiple HTS detectors, or analog filters alongside CMOS electronics, with the CMOS performing first stage amplification and/or feedback and/or digital signal processing, with only 10s of microns separating the two, both operating in the cold side. Such a system should have major performance advantages over the present state of the art. However, this effort has not been taken beyond the device concept demonstration. We propose to use the Peregrine semiconductor processing and ion damage Josephson junction fabrication technology to make monolithic devices with HTS detectors/filters integrated with CMOS electronics. The ion damage technology allows fabricating identical junctions with high reproducibility. This project seeks to take the technology to the stage where it is clear to industry that monolithic co-fabrication is viable for DoD systems.

Title:RF-based Geolocation I/Q Data Rate Enhancement: SHIFTER
Abstract:Real-time precision geolocation of COMINT signals of interest is a top priority in the GWOT. As communication signals and standards such as 3GSM, WCDMA, and CDMA2000 proliferate at unprecedented rates, the number of emitters is scaling dramatically. In the GWOT, almost any signal could be a potential signal of interest. The use of this kind of commercial technology and related technologies by extremists continues to expand dramatically. Clearly, the signals of interest target set is growing at a high rate. The Navy and the larger Intelligence Community is aggressively deploying fully interoperable net- centric systems for precision COMINT geolocation to help meet this challenge. It is reasonable to expect that sensor density will increase by a factor of 10 across the IC in the next five years. Consequently, current geo-processing techniques will soon become overwhelmed with signal data, will not be able to effectively manage high sensor counts and will have only a limited capability to simultaneously prosecute the growing class of high value targets. Addressing these challenges is the focus of this SBIR proposal, called SHIFTER. SHIFTER will “shift” the geolocation processing algorithms and processing hardware and software into the “high gear” needed to improve efficiency and scalability.

Title:Networked Positioning of Unattended Ground Sensors using JTRS radios
Abstract:Data Fusion Corporation (DFC) proposes the development of a prototype combat positioning system that will reduce fratricide, increase situational awareness (SA), and enhance combat effectiveness for UGS-to-Soldier based CID applications. The system design will use GPS, Tactical Unattended Ground Sensors (UGS), a modified-mobile adhoc network MANET, local ranging signals and a mesh network that will provide sub- meter position information, velocity, time (PVT) as well as ID. The sub-meter position is obtained using DFC’s legacy innovative positioning algorithms that uniquely combine (in a weighted least squares sense) lower accuracy absolute positions with highly accurate relative positions. Furthermore, DFC takes advantage of the mesh rigidity where appropriate. The minimal configuration can be a mixed network of dynamic nodes with or without GPS. GPS receivers only need be single carrier (L1) receivers processing the lower accuracy CA signal. This can be accomplished without any infrastructure. Should L1L2 P(Y) code receivers, and infrastructure be available additional accuracy and robustness can be gained. DFC will leverage its legacy positioning algorithms, GPS signal generator software and GPS soft¬ware receiver (Kober, W., 2004), implemented on a Field Programable Gate Array (FPGA), to develop this CID system. The original GPS software receiver design was sponsored in part by AFRL/SN, AFRL/MN and USASMDC.

Title:Networked Positioning of Unattended Ground Sensors using JTRS radios
Abstract:Unattended sensors are an important element of the Future Combat System (FCS) architecture. These include Unattended Ground Sensors (UGS), autonomous weapons such as the Intelligent Munition System (IMS) and miniaturized Unmanned Ground Vehicles (UGV) and Air Vehicles (UAVs). All of these applications have a requirement to use GPS for positioning. A “catch 22” exists between GPS security policy and operational security doctrine in cases where the system is left unattended or is not recovered (munitions excepted). While security policy requires a PPS solution, security doctrine states that PPS devices cannot be left unattended. Under this SBIR effort, NAVSYS proposes to develop a networked GPS positioning solution for UGS based on our patented TIDGET technology. The TIDGET uses COTS GPS components to capture a snapshot of GPS data which will be transmitted over the FCS network to an attended location with a JTRS radio where the GPS crypto processing can be performed. This allows a PPS solution to be calculated for the UGS without requiring crypto equipment to be left unattended in the field. We shall prepare a design for a Phase II system to demonstrate this capability and will provide simulation results to show the expected performance and network loading.

Title:PSIBED - Parametric Structures for Integrative Backscatter models and Environmental Database
Abstract:Understanding shallow underwater environment is increasingly important, but shallow water acoustic models depend on a large number of factors that interact in a non-linear fashion. There are many different acoustic back scatter models, but many of the models haven’t changed in years and some of the new ones rely on stochastic methods. What’s needed is a general acoustic model and environmental parameter structure that can parameterize existing models and associated environmental data, as well as act as a new acoustic modeling framework for shallow underwater environmental awareness. 21st Century Systems, Incorporated is pleased to introduce our parametric structure for integrative bottom backscatter models and environmental database (PSIBED…pronounced “seabed”). PSIBED develops a parametric space built on powerful geometric algebraic formalism for generalizing backscatter models as advanced layered sediment algebraic “versors.” The PSIBED algebraic signatures are used to describe and integrate models with parameters and environmental databases. PSIBED uses a multi-dimensional Clifford Fourier Transform structure for representing complex underwater environments and handles propagation of uncertainty as a first class property of PSIBED. Preliminary experiments reveal the potential to obtain, store, and utilize acoustic bottom backscatter information. This technology will ultimately lead to better underwater systems for use by manned and unmanned systems.

Title:Generalized Environmental Acoustic Model Structure for Bottom Backscatter
Abstract:Existing OAML-approved active acoustic models are under continuous evolution to take advantage of new theoretical and numerical developments and more powerful computational resources. These models are supported by OAML-approved environmental databases that are also constantly updated to accommodate the newly developed models and recent measurements throughout the world. The databases that describe the bottom include the Digital Bathymetric Data Base (DBDBV) multi-resolution bathymetric databases, the Low-Frequency Bottom Loss (LFBL) database, the Bottom Sediment Type (BST) database, and the Bottom Backscattering Strength (BBS) database. Recent physics based research on coupled scattering mechanisms and physics-based clutter as functions of the bottom’s geoacoustic parameters and bathymetry have offered the opportunity for a wholly new approach to developing a prototype generalized bottom database. This approach is based on understanding and describing the underlying physical mechanisms of reverberation and clutter (including bistatic geometries), and provides the ability to harness and integrate the information from the existing databases and new measurement techniques into a generalized bottom database. This database would furnish physics-based and/or empirical bottom parameters to model undersea acoustic propagation, deterministic bottom reverberation and stochastic clutter for emulation of false alarms.

Abstract:A novel broad-bandwidth modulator is proposed that has the potential for achieving low switching voltage in conjunction with low optical insertion loss. This is in stark contrast to conventional modulator designs that typically offer lower switching voltage only at the expense of higher insertion loss. Combining this novel modulator with a commercial diode laser is estimated to achieve a modulation slope efficiency of ~ 10 W/A. In Phase I Photonic Systems, Inc. will analyze and optimize the novel modulator geometry. Key parameters will be confirmed via measurements on a phase modulator that will also be fabricated as part of Phase I. Phase II will extend the novel modulator concept to the implementation of an intensity modulator with a bandwidth of 20 GHz.

Title:Lithium Niobate Thin Film Based Novel Geometric Electro-Optic Modulator
Abstract:Rainbow Communications proposes to investigate a compact, highly efficient, low driving voltage, broad bandwidth, high extinction ratio, low optical insertion loss, zero frequency chirp, electro-optic modulator based on thin-film lithium niobate materials, selected domain inversion technique, and optical-wave and electrical-wave velocity matched traveling- wave electrodes configuration for applications in RF photonic links and optical communication. The proposed EO modulator will be capable of modulating the intensity of optical light up to 40GHz with sub-volt driving voltage and up to 20-dB extinction ratio. The total fiber-to-fiber insertion is as low as 3-dB with zero frequency chirp. Several unique features distinguish it. First, Rainbow will fabricate a Mach-Zehnder (MZ) interferometer waveguide structure on a thin-film LiNbO3 material. Second, the domain of one arm of MZ will be inverted by using Rainbow¡¯s unique electrical poling process. Third, by using thin-film structure and optimized traveling-wave electrode design, this EO modulator can achieve both very broad bandwidth, over 40GHz and very low driving voltage, much less than 1-V with high extinction ratio. Fourth, by using Rainbow¡¯s novel package design and optical-fiber to waveguide coupling optimization, overall optical loss is very low and the efficiency of proposed EO modulator can be reach very high.

Title:Thin Films of Lithium Niobate for High Efficiency Electro-Optic Modulators
Abstract:In the past twenty-five years, electro-optic modulator technology has made significant advances in terms of performance. Modulator bandwidth, a key technical parameter, has been extended to 40 gigahertz in the commercial world and to 100 gigahertz and beyond in research laboratories. The greatest problem has been to achieve such bandwidths while still maintaining low drive switching voltage, low insertion loss, high linearity and high extinction ratio. Material electro-optic coefficient, optical loss, dielectric loss and permittivity all contribute to these parameters, with lithium niobate currently representing the best balance of materials properties. This Small Business Innovation Research Phase I project develops novel materials processing techniques that extract the maximum possible performance out of the lithium niobate electro-optic material. The new technology promises to substantially improve the performance capability of existing electro-optic modulators for Navy platforms.

Title:A LIGHTWEIGHT, UHF SATCOM DIPLEXER FOR USE IN EXPENDABLE BUOY SYSTEMS
Abstract:Existing filter technology does not suit the mechanical and electrical needs for use in expendable buoy systems. Current diplexer designs do not provide adequate rejection of the high power transmitter signal within the receive channel within the specified size, weight and acceleration constraints required for the Navy Buoy System. The proposed research includes the analysis and simulation of a high Q transmit filter that provides the required 90 dB transmit to receive stop band attenuation with low insertion loss to the transmit signal. One potential solution, which leverages NuWaves’ expertise in planar filters, utilizes an interdigital filter plated on a center circuit board. NuWaves’ initial simulations prove the sufficiency of the above approach. Phase I deliverables include a trade-off analysis of the expected diplexer performance vs. the design parameters. The expected diplexer performance will be based on a non-ideal simulation which includes real-world resistances and parasitics. The mechanical aspect of the effort includes physical size and packaging, thermal heat dissipation, resistance to high G acceleration, and housing metallization.

Abstract:This is a study for the development of a diplexer for Navy Bouy application. Approaches to the diplexer are a receive band-pass and a transmit band-stop filter with a diplexing circuit. These are designed using lumped components or transmission lines. Preliminary analysis shows that for the transmit filter, a transmission line band-stop filter using cross- coupling can meet the Navy requirements. For the receive filter a rod coupled filter using cross-coupling will also meet the Navy requirements. The band-stop filter can be a surface mount structure and thus will meet the shock requirement of 55 G's. For the receive filter, foam filling and rugged design can be used to meet the shock requirement.

As a first step for the development of a comprehensive tool, this proposal primarily focuses on developing frequency reuse methodologies and the SATCOM analysis. In particular, Navy’s legacy UHF SATCOM operation on MUOS will be analyzed in detail. The proposed tool will be developed on software platforms including MATLAB, STK, and QualNet. Feasibility of the proposed tool development approaches will be shown by demonstrating the integration of various software applications on the multiple platforms.

Title:Planning and Management of QoS-Based Mobile Wireless Networks
Abstract:Mobile Ad Hoc Networks (MANETs) are expected to play a vital role in the network-centric warfare paradigm. Among the many technical challenges that must be solved before MANETs can fulfill their envisioned role is the issue of network management. Policy- based network management is an effective tool for ensuring that users receive the Quality of Service(QoS), security, and other network capabilities they need. Policy-based networks employ intelligence in the form of rules to deal with situations that are likely to occur. When the policy-based network management scheme is targeted toward achieving QoS performance goals, the rules are designed to regulate both users and network resources to provide differentiated services among users. MANETs must employ a distributed approach to network management in which the individual nodes actively participate in the network management process. The proposed research is directed toward the development of prototype tools for expressing performance goals, monitoring network conditions, and taking actions to adapt network performance in real time. The results of the proposed effort will provide an architectural foundation for developing cognitive networks capable of allocating network resources to applications in an optimal manner in order to meet end-to-end performance goals

Title:Utility Oriented Planning and Management of Multi Segment QoS based Robust Mobile Wireless Networks
Abstract:We propose to develop a tool that will be used for the planning and management of QoS based mobile wireless networks. Our innovative techniques include: 1. Resources are allocated to aggregate classes of flows. 2. Significant performance advantage is gained by capitalizing on the availability of multiple communications transport segments and related routes. 3. A segment’s route may offer features that make it uniquely suitable for handling certain flows. They are measured by utility functions. The latter are aggregated to yield an overall measure of effectiveness. 4. We will develop management algorithms that provide for the joint routing and capacity allocations to be made for each flow class. Our models and methods will be applied to provide for failure, performance and topological planning and management operations for mobile wireless networks. 5. The proposed tool will include effective graphical user interfaces to define the underlying network system, traffic flows, and the per segment utility measures. Our combined mathematical and simulation based techniques enable the tool to carry out the planning process, and under each set of monitored network status conditions, to compute the required management actions and resource allocations, in realtime and in a highly effective manner.

Title:Network Planning and Real-time Automated Management System (NetPARAMS)
Abstract:Mobile ad-hoc networking is a technology that offers great value to warfighters. It promises self-forming, self-healing distributed networking ideally suited to the constantly changing environments of the battlefield. However, the reality of mobile ad-hoc networks (MANETs) has yet to come level with the promises. Military network planning does not yet enable planners to use MANETs as a connectivity extender, and to date MANETs are not reliable enough in either connectivity or throughput to reliably carry mission-critical information for the military. Given MANET’s mobile nature, it is necessary that MANETs evolve from self-forming to self-managed networks so as to help relieve planning requirements. The idea behind self-management is that MANET nodes collaborate to optimize their own routing and quality of service. In this effort, tools will be created to move MANETs close to self-managed networks and provide network monitoring and management that covers network from the wireline to the wireless. Algorithms will be generated and simulated to improve MANET connectivity and QoS. A planning tool will be created to help network planners use MANETs, and existing network management software will be modified to provide wireline and MANET monitoring and management.

Title:Shipboard Low Noise Amplifier Assembly.
Abstract:Auriga Measurement Systems and M/A-COM team up in this program to address the issue of mast-mounted shipboard low noise amplifier assemblies, which are required to have not only rigorous electrical performance but also to withstand severe weather and corrosive environments. The assembly being created in this work will contain a high power self-protective non-reflective limiter, a high linearity LNA and a low-noise bypass switch. To provide reliable, operator-free performance this assembly will feature built-in- test (BIT) and repair capability. In the event of a failure, the assembly will be capable of detecting the problem, notifying the operator, and automatically repairing the problem for seamless operation. Most of the components will be integrated onto a single MMIC. The end result will be a low-cost, compact assembly capable of state-of-the-art LNA performance. The small size will allow for easy integration onto existing and future mast top assemblies. In Phase I, a detailed design analysis will be performed and a layout will be generated. In Phase I Option, a prototype assembly will be built using commercial components and tested. In Phase II, the MMIC designed in Phase I will be fabricated, hermetically packaged, thoroughly tested, and prepared for commercial and military applications.

Abstract:The need for accurate satellite channel models and their implementation as a simulation tool is addressed in this proposal. Improved mathematical models are proposed which provide the flexibility to model diverse environments, and to do so more accurately than current models, for both stationary and non-stationary channels. Two simulation model strategies will be investigated for implementation of the mathematical models in software. In preparation for possible Phase II prototype implementation, a preliminary, high-level prototype design will be developed based on the results of the simulation model testing.

Title:Modeling Human Decision Making and Agent-Based Modeling of C3 Architectures in Warfare Assessment Models - MP 113-07
Abstract:Constructive Warfare Assessment Models are used by the OPNAV N81 Assessments to support budget planning decisions for future Navy programs. These models simulate approved Major Combat Operations and Global War on Terrorism scenarios that often span days to weeks, cover multiple warfare areas, and that attempt to capture details of tactics, CONOPS, threat behavior, weather, coalition forces' contributions, and equipment performance. One area that has been lacking in validity is command and control and tactics execution - areas that require modeling of human decisionmaking in a military context. It is not possible to separate the human decisionmakers and operators from equipment performance; instead, better representations of the humans-in-the-loop must be developed to capture true systems performance. This SBIR proposal provides examples from recent warfare assessment modeling of poor representation of human decisionmaking and proposes methods for improved simulation of these phenomena leveraging innovative uses of agent-based simulation.

Title:Knowledge-Rich Agents for Modeling Naval C3
Abstract:Current traditional warfare assessment simulations have been criticized for their simplistic modeling of command and control behavior, often resulting in inappropriate reactions to complex tactical situations, which can produce erroneous simulation results. Soar Technology, in partnership with Rolands & Associates, proposes to address this problem in the specific context of the Naval Simulation System (NSS). We will identify a framework to integrate agent software with NSS to allow different kinds of intelligent agents to enhance command and control behavior. We will also prototype a knowledge-rich intelligent agent based on Soar, a cognitive architecture for human behavior modeling that has been used successfully to build agents in military simulations over the past 10-15 years. Such knowledge-rich agents have the potential to bring human-level decision- making capabilities to simulations like NSS, resulting in more accurate modeling and assessment of new tactics.

Title:Modeling Human Decision Making and Agent-Based Modeling of C3 Architectures in Warfare Assessment Models
Abstract:We propose to build for the Navy a decision modeling system that can generate realistic, robust command and control behavior in a campaign-level constructive warfare simulation. This system will consist of a model editor and a model execution engine. The model editor will enable analysts to manipulate all aspects of the behavior model without the assistance of a programmer, via an intuitive visual editor in which the user assembles behaviors from building blocks, similar to drawing tools like Visio. Visualization tools will allow the analyst to quickly understand, modify, and extend complex models. The model execution engine, which will integrate easily with constructive simulations, will dynamically determine what actions are taken by simulated entities. It will support both strategic and reactive behavior in situated intelligent agents that can reason about and adapt to adversary behavior. It will allow the analyst to observe the “mental state” of the model in order to understand the rationale behind its actions and decisions. The proposed system will represent an evolution beyond the current generation of behavior models, enhancing the realism, sophistication, and usability of warfare models. We will absolutely demonstrate the feasibility of our ideas through the development of a Phase I prototype.

Title:Modeling Human Decision Making and Agent-Based Modeling of C3 Architectures in Warfare Assessment Models
Abstract:Toyon Research Corporation proposes to develop the capability within a constructive simulation to model military command and control decisions given information from many sources. In particular, Toyon will address the problem of intelligently redeploying forces given changing conditions reflected in the information provided by military sensors, including complex reactions such as learning from past experience. Toyon will use a layered approach; one layer will be a threat propagation layer, where single elements are modeled by a dynamic Bayesian network and relations between elements are modeled by a cellular-automaton based approach. The second layer will scalably simulate human command and control decisions by modeling each asset as an agent bound by simple local rules. In Phase I, we will develop these algorithms to specifically address the problem of re-deployment of ISR assets. We will show the utility of our work in a proof- of-concept scenario where the complex behavior of the cellular automaton and agent- based algorithms will allow a richer decision-making process than a simplistic rule-based decision tree. In Phase II, we shall design and implement a prototype model integrated within a mission-level simulation to model sophisticated C3 behaviors in a campaign-level scenario of utility to the Navy.

Title:High Voltage High Frequency SiC Switch
Abstract:The stringent power quality, size, weight and volume specifications for operating high power hardware in more-electric warships require the development of >100 kHz, 2 kV Silicon Carbide based power devices. GeneSiC proposes the development of a single chip power subcircuit using a unique and innovative Silicon Carbide SuperJFET technology. Apart from better circuit integration this approach offers more than an order to magnitude higher switching frequency, 2X higher current density, higher chip yield and highly reliability as compared SiC power MOSFETs. The reduction of interconnect parasitics and passives dramatically improves the temperature, radiation and power density metrics. The first challenging task of this program is the analytical, epitaxial and cell layout designs of these high risk/high reward concepts. Next, a novel SiC fabrication process sequence will be implemented in a commercial SiC foundry. The economical production of these devices allows a large number of these basic building blocks to be produced. A MIL-STD device test plan and circuit performance routine will be implemented. A comprehensive cost model will be developed for commercial feasibility. The initial demonstration of design and analysis of 2 kV power circuit is targeted, to enable MW-class power devices in Phase II and beyond.

Title:Low cost, lightweight, low power Precise Positioning System (PPS) GPS Solution for Software Defined Radios
Abstract:Under this proposed effort, NAVSYS will leverage our expertise with developing ultra- low power GPS solutions to develop a software GPS receiver solution that can be embedded in military software defined radios that will be used for handheld, sensors and weapon applications. The objective of this effort is to develop a top-level software design for a lightweight GPS application, “GPS-Lite”, which is capable of performing PPS GPS positioning within a small form factor JTRS radio. We shall focus this effort on developing a design suitable for transition into the JTRS HMS radios that is also extensible to all tactical radio form factors and adaptable to sensor and weapon use. The architecture study performed shall identify the radio resources that will be used by the GPS-Lite application and the software components to be implemented. We will consider methods for partitioning the GPS-Lite functions to optimize use of the processing and security resources within the JTRS HMS to minimize the power required to compute a GPS PPS fix. We will also perform lab testing to validate the processor and relative power consumption requirements and develop a plan to build an unclassified prototype of the GPS-Lite application under Phase II for test and evaluation.

Title:Advanced GPS Solution for Software Defined Radios
Abstract:We propose an advanced GPS solution for software defined radios (SDR) for military users. Different from conventional software GPS receivers that merely mimics what a hardware receiver does, the proposed GPS solution sets forth advanced signal processing techniques along the signal and data processing chain, some of which are difficult, if not impossible, to implement within conventional receiver architectures, thus allowing the realization of the full potential a software receiver can possibly offer. For military applications, the design emphases are therefore placed on dynamic range, interference suppression, and weak signal operations. In the Phase I base effort, the proposed algorithms will be formulated and a subset of which will be investigated for implementation within the Software Communications Architecture (SCA). In the Phase I option effort, the design of a hardware accelerator will be conducted to implement a cascaded DFT/IDFT on FPGA. In Phase II, the validated algorithms and their designs will be prototyped for demonstration.

Title:Advanced Propellant Bonding Agent
Abstract:ANW seeks to develop a new class of propellant bonding agents based on its proprietary titanyl compound discovered in March 2007. This titanium based compound has already demonstrated an ability to act as a plastic and epoxy cross-linker that improves performance beyond existing specialty chemical additive levels. ANW believes similar improvements can be achieved in solid fuel propellant systems. ANW proposes researching and identifying compatible chemical reactants that will chemically bond to its titanyl molecule and act as a cross-linker in the Navy’s solid fuel propellant systems. ANW’s proposal is broken into 6 tasks including synthesizing reactive linkers, identifying the best linkers, characterizing physical properties of the derivatives and analyzing both chemical and physical characteristics of the bonding agent. Improvements in stability and mechanical properties will improve propellant aging, frequency of insensitive munitions (IM) and will reduce life- cycle costs while improving safety for existing solid fuel systems.

Title:Multifunctional Bonding Agent for High Energy Propellants
Abstract:Bonding agents (BAs) are critical components of solid propellants that facilitate processing by improving interfacial interaction between the surfaces of oxidizer grains and the binder resin. The BA cures with the binder to produce void-free solid propellants that exhibit desirable storage and burning properties. New, multifunctional high energy propellants (MHEPs) contain oxidizer components that are not compatible with current BAs or with Polyether PUR binders. Infoscitex proposes to develop a new, soluble Multifunctional Bonding Agent (MBA) that interacts strongly with each type of propellant grain; including, AP, AN, AN, NE, GAP and ADN. The MBA migrates to the grain surface where it hydrogen-bonds to form a thin, tenacious surface layer that reacts with PE-PUR binder resins during cure. The MBA will enable production of void-free MHEP propellants that exhibit superior strength, toughness, stability and burning characteristics. In Phase I, the MBA will be synthesized and processed with MHEP oxidizers to produced the new propellant. Tensile strength and elongation will be measured to demonstrate improved interfacial interaction with MHEP oxidizers and chemical reaction with binder resins. In Phase II, the MBA will be refined, scaled-up and formulated into prototype MHEPs that exhibit superior stability, performance and reliability.

Title:Mapping and Tracking Early Stage Damage for Structural Health Monitoring of Material Handling Equipment
Abstract:It is imperative that catastrophic failures be prevented in critical load handling equipment, such as missile hoists. Improved NDE methods are required that can be rapidly applied in the field to assure integrity of structural components without requiring extensive training of field personnel. JENTEK’s Meandering Winding Magnetometer array (MWM®-Array) sensors have proven capabilities for detecting early stage fatigue damage and cracks in metallic components and the ability to produce highly repeatable, spatially registered digital images of material properties. MWM-Arrays are thin and flexible, conform to curved parts and parts with varying curvature, can be fabricated in a wide variety of shapes and sizes to enhance inspection of specific components and can be embedded for structural fatigue and stress monitoring. By making baseline scans of critical components and creating digital maps of material conditions, very small changes can be detected throughout the life of the steel components that can identify early stage fatigue damage, early stage fatigue cracks, results of an overload event, and changes in precursor conditions, such as residual stress state, that can identify areas of higher susceptibility to future damage. This proposal addresses the need to adapt and customize this technology for specific critical load handling equipment.

Title:Use of Bus Pipe Technologies to Replace Medium and High Voltage Cables
Abstract:U.S. Navy has the goal of an improved power distribution system for future naval construction. This power distribution system must be designed for survivability and continuity of electrical power supply. In general, ship service electric power and future electric propulsion power requirements are approaching hundreds of megawatts. Today’s shipbuilders face major challenges with the use of standard cable systems at medium voltage levels due to cable stiffness, and cable bend radius requirements for distributing high current around the ship. This proposal demonstrates the advantages of the Insulated Bus Pipe (IBP) technology, installation benefits and weight and space savings associated with IBP as an alternative to traditional shipboard cable systems. The IBP system is currently used in the utility industry and in shipboard applications on several passenger cruise ships. IBP is a more efficient medium & high voltage transmission line over cable for Integrated Power System (IPS) on ships due to weight reduction, cable volume, and installation time. The U.S. Navy has determined that current commercial IBP system can not pass a 3 hour gas flame circuit integrity flame test. It is the focus of this proposal to improve the high temperature performance by developing an insulating matrix to handle the temperatures associated with the 3 hour gas flame circuit integrity flame test.

Title:Unmanned Surface Vehicles (USV) At-sea Fueling
Abstract:The first objective is to design a system for this initial fueling immediately following launch, with apparatus that can be connected prior to launch. The second objective is to significantly reduce the time to refuel a USV between mission sorties by refueling it from the LCS without bring it aboard the LCS. The third and final objective is to move the fuel source offboard from the LCS to another craft, such as a dedicated “fuel tanker” USV. With this system, the fuel can be taken to the mission area to refuel the USV during its mission. This saves the lost mission time of returning to the LCS for refueling. In addition, reducing the dependency on the LCS will free the LCS to execute other tasks that may be a considerable distance from the USV’s mission area. Each of the three systems developed to meet the specified objectives will work as a standalone solution; together, they will be capable of fueling USVs in all of the specified scenarios.

Title:Reduced Unmanned Surface Vehicle (USV) Motions For Reliable Recovery
Abstract:Safe and reliable launch and recovery of small offboard assets is important to the concept of operations for the Littoral Combat Ship (LCS), as they are deployed to complete a wide range of missions. The LCS design specification requires launch and recovery of watercraft to be completed within fifteen minutes in conditions through Sea State 4. These operations are expected to be difficult because many of the missions will be conducted using unmanned surface vessels (USV). Several recovery concepts have been proposed. However, the development of a single, reliable system has been complicated by the pursuit of two LCS design variants with significantly different general arrangements and seakeeping properties. This proposal describes design and analysis of a wave monitoring and control system to reduce the relative motion between the USV and the LCS during the recovery process. The wave monitoring system will be used to provide initial conditions for forecasting conditions at the LCS to estimate calm periods as well as to provide input to the control system. The overall system is intended to work with existing recovery hardware for both over-the-side and stern launch and recovery systems.

Title:Advanced Direct Energy Conversion for Power Electronics Cooling
Abstract:A new metal matrix composite material consisting of natural graphite particulates processed into a designed reinforcement architecture that, after pressure infiltration casting with molten Al alloy, results in materials with thermal conductivity (TC) controllable over a range of 600 to 750 W/mK and thermal expansion controllable over the range of 7 to 3 ppm/K. This material is proposed as a spreader and as a natural circulation cooled heat sink to be integrated with a solid state thermoelectric module to generate energy from waste heat sources. This energy can be utilized for powering a pump for circulating fluid for cooling a power conversion module. The cold plate for the power conversion module can also be made from this high thermal conductivity material and can be optimized for low pressure drop and low power consumption in pumping liquid through the cold plate. The proposed scheme can not only maximize the power generated from any given thermoelectric or other solid state technology, but also use that power most efficiently by minimizing the power drop through the channels

Title:Wastewater Treatment Module
Abstract:Navalis has developed and tested a family of scalable marine advanced oxidation wastewater treatment systems that have high potential to meet the physical and operational requirements of SBIR NAVY 07-207. The modular component nature of the Navalis Orion™ makes it ideally well suited for arrangement into a transportable system for use as an LCS Wastewater Treatment System Mission Module. Navalis proposes its 2.5 gpm Orion variant (3,000 gallons/day) as the base system for this project. Testing of the parent design gives a high degree of assurance that it will be able to process waste of volume and strength expected aboard LCS, provide quick start capability, use a minimum of tankage (no additional onboard tankage requirements) and provide effluent meeting the requirements of IMO Resolution MEPC.159(55), with real-time effluent quality monitoring. The focus of Phase I will be to tailor our system to the requirements of the LCS as a reconfigurable mission system. Phase II will be to build a working prototype for Developmental Testing at Navalis, NSWCCD to demonstrate and validate the performance goals established in Phase I, and in Phase III, through Operational Test & Evaluation, demonstrate and certify the functionality of the module in each of its required functions.

Title:Electrochemical Wastewater Treatment Module
Abstract:Reactive Innovations, LLC (RIL) proposes a SBIR phase I program to demonstrate a modular wastewater treatment system to supplement Littoral Combat ship (LCS) wastewater capacity for increased or mission system demands. Wastewater treatment utilizing large storage tanks currently in use on cruise vessels and some Navy ships will not meet the requirements for a supplemental compact system. In addition, regulations governing effluent discharge into open waters are becoming increasing stringent as the intensification of industrial activities in the last 100 years has inevitably caused severe environmental pollution with dramatic consequences to the atmosphere, aquaculture, our water supply, and agriculture. Advanced wastewater treatments are currently being developed for water conservation and recycling in both centralized and decentralized applications. We propose a novel chemical oxidation system to treat graywater and blackwater onboard naval vessels. Our proposed approach will advance onboard treatment of wastewater by utilizing a flow through tankless reactor which both generates an extremely powerful oxidant and chemically reacts that oxidant with contaminated waste streams with no toxic byproducts.

Title:Watercraft Controlled Approach System
Abstract:Athena Technologies Incorporated (Athena) proposes to demonstrate a watercraft recovery control system to control, monitor and manage the recovery sequence of watercraft aboard small surface combatants. The solution leverages Athena’s capabilities in vision-augmented estimation, control and path planning, and the field-proven multistate nonlinear Kalman filter (KF) attitude solution currently used in Athena's GuideStar™ products. The objective is to provide active real-time tracking of multiple vehicles throughout the approach and recovery sequence, under a variety of environmental conditions, through sea-state 4 conditions. The proposed system will be used to track vehicle progress toward the recovery point, provide guidance recommendations to the operator, and evaluate the feasibility of a successful docking, generating warnings when appropriate. This information will be presented to the operator within an efficient, user-friendly interface, on a rugged outdoor-viewable display, which will be usable as a secondary display when the operator is directly controlling the vehicle during the recovery evolution.

Title:Operator-aided Autonomous Recovery System (OARS)
Abstract:The U.S. Navy’s plans for addressing asymmetric threats of the twenty-first century relies heavily on Unmanned Surface Vehicles (USVs) and manned Organic Offboard Vehicles (OOVs) for reconnaissance, force protection, mine detection, special operations, anti-submarine warfare (ASW), and intelligence collection mission. Rapid launch and recovery of these vehicles will be critical to mission success. Currently, mechanical recovery techniques are highly dependent upon the unique operator controls resident on each watercraft to guide the vehicle into a final recovery position. In the case of USVs, the operator is hampered by limited sight lines to the incoming vehicle and surrounding seas, and has a challenging “reverse-perspective” for controlling the incoming vehicle. This current process results in operational limitations, increased recovery timelines, and increased risk of damage to the deployed vehicle and the ship. Robotic Research, LLC in partnership with General Dynamics Robotic Systems (GDRS), proposes the development of the Operator-aided Autonomous Recovery System (OARS), a standard control system for recovery of USVs and manned OOVs from a Littoral Combat Ship (LCS). OARS will make use of an established Hierarchical Control Architecture and Tactical Control Unit that have been effectively used for the control of several successful Unmanned Ground Vehicles (UGVs).

Title:Rapid Asymmetric Multi-agent Aerial Intent Determination (RAM-AID)
Abstract:The Navy’s conversion to a ‘Rapid Response – Force Protection’ tactical mindset due to asymmetric threats requires a change in hardware to support the new tactics. Exposing a potential adversary’s intent is key to determining the actions a commander should take. Unfortunately, with regards to aerial attacks from low slow-flying aircraft near shore, the Navy has few tools beyond what was historically available: human eyes and crew- served weapons. Most of the powerful capabilities, such as long range radar and the AEGIS weapon system function poorly near shore. The Navy needs a solution similar to AEGIS, but capable of functioning in a wider range of areas. 21st Century Systems, Incorporated is pleased to propose to research and develop the Rapid Asymmetric Multi- agent Aerial Intent Determination system (RAM-AID), which will be an Intelligent Agent decision support system that will use available sensor data to track, fuse and provide decisions and concise recommendations to the commander and ATFP decision makers; based on discernable and interpretive analysis of intentions. By coupling advanced persistent passive and active sensors with the exceptionally fast decision support capability inherent in intelligent agent software, a commanding officer will have an optimal solution set for this asymmetric threat in rapid fasion.

Title:Autonomous Persistent Surveillance and Targeting for the Asymmetric Air Threat (APSTAAT)
Abstract:Maritime asymmetric air threat detection begins with an in depth comprehension of the tactical picture. Security lies in the ability to sense threats in all environments. Advanced Optical Systems, Inc. (AOS) and Technology Systems, Inc. (TSI) have joined together to propose APSTAAT, a system for autonomous persistent surveillance for the asymmetric air threat. Low, slow flyers are threats to surface combatants at anchor or steaming in the littorals. APSTAAT will provide autonomous threat ID and allow a single operator to act as an entire watch team, supporting optimized manning concepts. The system will provide persistant surveillance even during times when the ship is at a relaxed readiness condition. APSTAAT consists of three software/hardware modules that can be integrated into the existing DDG 1000 system design or other surface combatants. These modules include: an Object Recognition System, an Expert System, and an Augmented Reality display. Accepting inputs from the wide variety of existing sensors. APSTAAT finds and assesses the threats, fuses and geo-registers the data in an augmented reality view, and hands off precision targeting data to weapons mounts. This powerful combination gives the commander unparallel situational awareness and the edge he needs to win the fight.

Title:Unmanned Vehicle Security System
Abstract:Unmanned Surface Vehicles (USVs) deployed beyond the direct observation of the host Littoral Combat Ship are susceptible to significant threats due to vandalism, piracy, and/or fouling from fishing gear. Advanced Acoustic Concepts (AAC) and Accurate Automation Corporation propose a multi-sensor fusion and dissuasion solution that is robust and cost effective for protection of USVs. This Unmanned Vehicle Security System (UVSS) will consist of a set of optimally selected surveillance sensor technologies assembled via a “peer review process” in which “best of breed” solutions are identified from a representative field of competitors. This represents a departure from the tradition approach of offering a “magic bullet” solution, and allows the system to integrate the best technologies available regardless of the origin. AAC has a successful history of applying the best of breed/peer review process to Navy surface fleet sonar systems, and provides expertise in underwater and air acoustic surveillance as well as signal processing and sensor integration. Accurate Automation has extensive expertise in USV development and USV threat dissuasion technologies, and will be developing both lethal and non-lethal dissuasion systems for the UVSS. Once the optimal set of surveillance sensors and dissuasion tools have been identified, a system design will be produced.

Title:A Modified GMAW System for Distortion Reduction and Travel Speed Increase through Separate Heat Input and Deposition Rate Control
Abstract:Gas Metal Arc Welding (GMAW) is the most widely used welding process. It is also the major process used in shipbuilding. In traditional GMAW and all its modifications, the current which melts the wire is the same as the current which heats the base metal. The base metal heat input is thus proportional to the heat which melts the wire. To maintain a minimally acceptable productivity as measured by the wire melting speed, the base metal heat input is typically much greater than the required to control the distortion at an acceptable level. In the modified GMAW proposed to reduce the post-weld distortion and increase the travel speed, a bypass torch is added to an existing GMAW system to bypass part of the current so that the base metal current is smaller than the wire melting current. Further, by controlling the bypass current, the base metal current can be controlled at whatever the desired level is while the melting current can also be controlled at whatever the desired level is. Hence, in the modified GMAW, the productivity is decoupled from the base metal current and the base metal heat input can thus be reduced without affecting the productivity. As a result, reducing heat input thus distortion and increasing travel speed can be achieved simultaneously. The Phase I project will prove the feasibility of the modified GMAW technology for its practical use in welding a typical ship structure material DH36 at flat, horizontal and vertical (down or up) positions.

Title:Exercise Torpedo Buoyancy (Recovery) System
Abstract:ANT has recently developed a similar recovery system for our own autonomous vehicle. ANT’s current system lifts a vehicle of lighter negative buoyancy (~64lbs rather than 200 lbs). The system is also designed to operate at less maximum depth (200 m, rather than 900 ft). These changes will necessitate the use of a larger volume lift bag and a modified compressed gas canister for the MK54 torpedo.

Title:Exercise Torpedo Buoyancy (Recovery) System
Abstract:Retrieval of field exercise torpedoes by the US Navy requires an inflatable Buoyancy Recovery System (BRS). The current hot gas system is expensive to operate/maintain with expended material and is labor-intensive to refurbish. Systima is proposing a new, lower cost torpedo buoyancy system which eliminates the need to cleanout the byproducts of the inflation system, the associated inflation system solid propellant grain costs, and assembly/operation complexity of the current solid propellant based torpedo buoyancy systems. The Systima inflation system approach is estimated to provide a cost savings in excess of $1,000,000 per year. By utilizing modern, refillable, high pressure composite gas bottles as the energy source for inflation of the system, a lightweight, high performance system is engineered which also features improved handling and logistics due to the lack of explosive components. Robustness is enhanced through a differential pressure control system and deployment features are designed to provide safer, easier retrieval by naval personnel.

Abstract:The team of 3 Phoenix, Inc. and Northrop Grumman Corporation propose to develop and evaluate technology that provides a substantial performance improvement to the problem of clutter discrimination. The team describes algorithms proposed to achieve substantial performance improvement. The proposed technology includes algorithms to perform detection of targets in heavy clutter, algorithms for extracting novel physics-based target features, and classifier technology for discriminating sea spikes from periscopes. Under Phase I, we propose to implement the algorithms and use recorded radar data to evaluate the technology. We propose to analyze the feasibility of implementation of the technology in software.

Title:Multi-wavelength high-energy pulsed laser source
Abstract:Q-Peak proposes to develop a multi-wavelength, high-energy, all solid-state source based on the combination of an efficient, high-energy, 1047-nm Nd:YLF laser, a tunable optical parametric oscillator (OPO) and a multi-wavelength Raman laser. The pulse-pumped, repetitively Q-switched, Nd:YLF Master Oscillator – Power Amplifier (MOPA) system will provide 250-mJ, ~200-nanosecond pulses at 1047 nm with the pulse format and rate in accordance with the requirement to the temporal mode of operation. The Nd:YLF output will pass through a second-harmonic generation (SHG) crystal to be efficiently converted to green output at 523.5 nm. The green power will act as a pump for an LBO-based optical parametric oscillator (OPO), which generates two output beams, a signal and an idler. The signal output from the LBO OPO will be tunable in the near infrared (NIR) from 700 nm to 750 nm, by angular tuning the OPO nonlinear crystal, with pulse energy of ~ 50 mJ. The green power will also be used as a pump for a Raman laser. The Raman laser will provide pulsed, multiple-wavelength- output in the visible wavelength band from 550 nm to 600 nm with maximum pulse energy of ~50 mJ.

Title:Laser Technology for Shipboard Defense
Abstract:Laser pulse generation has emphasized either minimum pulse duration, typically to maximize peak power, (mode-locked pulses), or maximum energy per pulse (q-switched solid state lasers). Both of these approaches have pushed pulse durations well below 100 ns. Modern broad stripe diode lasers with relaxation times in the nanoseconds can be modulated to produce the required pulse durations and energies with simple modulation of the drive current and mimimal risk to the diodes themselves. However, diode lasers capable of achieving the power levels required emit light outside the spectral region of interest have notoriously poor beam quality as well as substantially greater divergence angles than required for ship self-defense applications. During the course of this Phase I program, a novel technique for spatial and spectral conversion of diode laser pump light into the wavelengths and divergence angles of interest will be designed and analyzed. A proof of concept will be demonstrated using a Nd:YAG laser as a simulated diode laser pump. The final report will include preliminary design parameters for scaling up the proof of concept for a Phase II prototype to achieve 50 mJ 200 ns pulses at 1 kHz repetition rates in each of the desired wavelength regions.

Title:Laser Technology for Shipboard Defense
Abstract:SA Photonics is pleased to propose a program to develop a double-band shipboard defense laser system (DOSLS) based on our High Energy, and Tunable pulse Optical Source (HETOS) technology for shipboard defense applications and other military and commercial applications. The proposed light system is flexible, scalable and affordable. It will be constructed using mainly commercial fiber-optic components and therefore, is reliable, highly efficient, rugged, compact, lightweight, easy to use and low cost. DOSLS' performance either equals or exceeds the requirements in every category. In a HETOS design there are three key enabling technologies that offer significant improvements over other methods of generating a visible/near IR source, they are: • Regenerative fiber amplifiers (RFA) • Generation of optical pulses with adjustable pulse width and pulse repetition rate • Low loss Band Separator and Signal Combiner (BSSC) The regenerative fiber amplifiers reuse pump power and therefore improve efficiency and reduce the total number of stages of fiber amplifiers. This enables a HETOS to have >100X reduction of prime DC power consumption for burst mode operations compared to a conventional laser source using bulk optics.

Title:Fiber Optic Vector Sensor Arrays
Abstract:Twinline and vector sensor towed arrays correct the left-right ambiguity inherent in hydrophone systems and offer significant performance and tactical advantages against noisy interferers in a non-isotropic noise environment. A vector sensor array is preferred because it provides similar capability to twinline and uses a single line array versus towing two independent arrays. This difference dramatically reduces submarine deployment, retrieval, stowage and handling requirements. Vector sensor arrays are comprised of a series of sensor “suites” that consist of three orthogonal accelerometers and a hydrophone. Multiple spatially separated, fiber optic accelerometer and hydrophone sensors are used in each suite to improve flow induced noise performance. Using Chesapeake Sciences’ TB-33 fiber optic hydrophone and towed array architecture coupled with the Navy’s model for a fiber optic accelerometer provides an ideal opportunity to leverage the designs into a single vector sensor array. TB-33 automated manufacturing and minimal outboard electronics improves reliability and decreases manufacturing costs. Our Phase 1 effort focuses on designing a Thinline Optical Directional Array (TODA), developing a performance specification and prototype sensor. Phase II plans include assembly of a prototype array for extended Shallow Water Advanced Prototype (SWAP) in-water testing and analyses.

Title:Fiber Optic Fabry Perot Vector Sensor Arrays
Abstract:Conventional accelerometers are non-optimal for many submarine sensor applications, especially for hydrophone towed arrays. Limitations include size and weight, need for heavy copper conductors, susceptibility to electromagnetic interference and electrical cross talk, and limited cable drive capability. VIP Sensors proposes to develop a sensor measuring system consisting of optical MEMS vector sensors distributed on a single optic fiber, each working at different frequency ranges. A broadband high intensity LED is used as a light source for the serially connected accelerometers. Each optical sensor, tuned to work at a unique frequency of the spectrum, shifts (modulates) its corresponding input signal frequency proportional to the measured pressure and lets pass all other frequency signals. The light at the end of the optic fiber contains the information for all sensors at different preset frequency slots, in a scheme similar to Wave Division Multiplexing. An optical demultiplexer located at the fiber end separates the signal spectrum. A photodiode array converts the photons to electrons and specialized circuitry quantifies the frequency shift corresponding to each sensor. The sensor is sculptured on silicon wafer using MEMS processes. It consists of a mass hanging on a flexure hinge. A strand of optical fiber is attached on the surface of the sensor chip with an intrinsic Fabry Perot cavity laid between the mass and the rigid frame. The inertia force rotates the hanging mass about the flexure hinge. The mass displacement stretches or compresses the fiber. The strain in the fiber changes the length of the Perot cavity, which causes the shift of the incoming light wavelength. The shift of wavelength is thus proportional the inertia force or acceleration.
