Title:Protective Suit Environmental Control System for CBRN, Hazardous and Emergency Responder Applications (PSECS)
Abstract:Aspen System proposes to design, develop, fabricate and test a cooling/dehumidification system for use by MOPP 4 encapsulated warfighters. The system is designed to remove humidity and moisture from the interior of the MOPP 4 ensemble while maintaining internal temperatures at below 85 degrees F. Humidity levels inside the suit will be maintained at between 10% and 50% while temperatures will remain between 70 and 85 Degrees F. Outside ambient conditions are specified at 125 degrees F dry bulb temperature. The system will be fully compatible with the MOPP 4 Mission and will not adversely affect current CONOPS doctrine. The system will be lightweight, versatile, and have multiple mounting options so that individual preferences for mounting and differing mission requirements can be accommodated with a single system. The Phase I effort will unequivocally demonstrate the performance of the system and show, through testing of a breadboard design, the full feasibility of the technology to meet the weight, volume and power consumption constraints required for the CBRNE MOPP Level 4 mission.

Title:Cooling and Dehumidification for Protective Suits
Abstract:Protective suits that isolate a marine from the environment can also build up excessive internal heat and humidity, impairing performance and possibly leading to heat casualties. We propose to develop an innovative environmental control system that will maintain a cool, dry environment inside protective suits. There are two key innovations: (1) a novel cooling process that provides very high efficiency, and (2) a unique cooling garment that removes both heat and humidity from the suit interior. In Phase I we will prove the feasibility of our approach through laboratory tests that demonstrate both of the critical innovations. We will use the test results to produce a conceptual design for a full-size system.

Title:Protective Suit Environmental Control System for CBRN, Hazardous and Emergency Responder Applications (PSECS)
Abstract:This program is expected to result in a miniature drying and microclimate cooling system for the interior of MOPP Level 4 protective suits. The innovative approach chosen for this project will result in a gravity-independent drying/microclimate cooling system that operates with JP-5, or other heavy fuels, universally available to the user, enabling continuous use over extended missions. The integrated power system will create all of the electrical power necessary for the system, eliminating the need for batteries to run the system. The result will be a very compact climate control system that will keep users of MOPP Level 4 and commercial HAZMAT personal protective suits both cool and dry.

Title:Protective Suit Environmental Control System for CBRN, Hazardous and Emergency Responder Applications (PSECS)
Abstract:Current microclimate system technology is not capable of meeting the Navy’s requirements for cooling capacity, volume, weight, or dehumidification. For these systems to be successful, they must only require resources that are readily available and must not add excessive bulk to the items a soldier carries into combat. Mainstream will improve upon existing technology by designing a system that requires only standard military batteries and is volumetrically efficient, using less than 200 in3.. In addition, the proposed technology will have manage humidity inside an enclosed protective suit. At the completion of the proposed Phase I effort, Mainstream Engineering Corporation will deliver the complete design for an active, man-portable, thermal-protection system. In addition, the Phase I effort will include an experimental evaluation of the major system components. This in-depth design and experimental evaluation will enable fabrication of a full-scale prototype at the start of a Phase II contract.

Title:Next Generation Helmet System
Abstract:Artisent, Inc. will develop, test, and deliver a Next Generation (N-Gen) helmet for the Marine Corps ground forces that provides a modular system for headgear protection and sensory enhancement. Next generation, lightweight ballistic protective materials will be employed in developing a new ballistic shell capable exceeding the ballistic performance of the current Light Weight Helmet (LWH) at reduced weight. A new liner/suspension system will incorporate impact absorbing pads and a fully adjustable internal head-band to provide a comfortable yet stable fit and improved protection against non-ballistic events. Artisent will design and integrate hearing protection and a mandible and visor for additional face and eye protection. A lightweight, integrated accoutrement support structure which surrounds the lower perimeter of the ballistic shell will provide a consistent mounting platform for the addition of night vision goggles and other commonly- used tactical equipment. In Phase I Artisent will demonstrate feasibility for a modular architecture and deliver drawings and draft specifications for a fully integrated modular system. In a Phase I Option, Artisent will conduct an anthropometric study to predict the sizing tariff for the helmets. A 3-D CAD model assembly of the N-Gen helmet system will be created for Phase II reference and component refinement.

Title:Next Generation Helmet System for Marine Corps
Abstract:CFDRC in collaboration with GENTEX®, manufacturer of the Marine Corps Lightweight helmet (LWH), Advanced Combat Helmet (ACH) and Development Test units of the new Enhanced Combat Helmet (ECH) will develop a Next Generation (Next-Gen) helmet for the Marine Corps ground forces that provides improved protection against blunt force, ballistic and blast impact, fragmentation, flash heat, and battlefield noise. This will provide the Marine Corps a new helmet design with improved survivability, modularity, and reduced weight over the current Light Weight Helmet (LWH). In addition, critical human factor elements such as comfort, thermal management, weight, stability/center of gravity, safety, and seamless integration with helmet mounted devices will be addressed. In Phase I, the new helmet will be conceptualized and designed. At the end of Phase I project, the design, CAD models, materials, helmet components, retention/suspension systems, along with a Phase II plan will be provided to the Navy. In Phase II program a prototype helmet will be developed and tested. In Phase III we plan to conduct field tests with the Next-Gen helmet.

Title:DoD Engine Efficiency Enhancement Technology
Abstract:Diesel engines are widely used in commercial and military vehicles, as well as some light duty vehicles. The compression ratio is a compromise between power, economy, and cold startability. The optimum ratio for economy is near 14:1 to 15:1, whereas the necessary compression ratio for cold starting ranges from 16 to 22:1 depending on the specific design of the engine and its application. This is too high for best economy and optimum boost. The proposal objective is to demonstrate a simple mechanism to vary the compression ratio between high (for cold starting) and low (for warmed-up running). This is accomplished during engine starting by causing the intake valve to close early (at bottom center), providing up to three ratios additional compression. Our plan is to reconfigure the valve mechanism to provide the desired function. Once running, the cam operates the valve normally. Minimal or no engine block modifications are anticipated. The work proposed is to develop the reconfigured valve mechanism and demonstrate it’s viability in a bench test rig with appropriate control strategy. For the SBIR OPTION, a system will be installed on one cylinder of a multi-cylinder engine and motoring tests run to demonstrate effectiveness.

Title:Stable, Premixed-Charge Compression-Ignition (PCCI) Engine Using Real-Time Combustion Feedback
Abstract:Mainstream Engineering Corp. (MEC) proposes developing a Pressure-Feedback, Premixed-Charge Compression-Ignition (PF-PCCI) retrofit kit for military diesel engines. PCCI combustion uses extremely early injection under certain load/speed points to dramatically improve combustion efficiency and reduce emissions. PCCI also improves the overall fuel-conversion efficiency by allowing the combustion of very lean mixtures which are more favorable thermodynamically. Unfortunately, PCCI combustion, which has received a great deal of recent attention by the engine research community, is difficult to control because the combustion depends strongly on the complex chemical kinetics of the fuel. MEC will address this problem by using a new class of pressure sensor to provide real-time feedback on the combustion phasing. That real-time control signal, in conjunction with a high-pressure electronic fuel injection system, will be used to stabilize PCCI combustion. In Phase I, MEC will design and implement the PF-PCCI hardware and ECU software and perform dynamometer testing to demonstrate its brake fuel consumption, emissions, and noise. In Phase II, MEC will transition the Phase I prototype hardware to a nearly production-ready retrofit kit that will be delivered to the Marine Corp for further evaluation.

Title:DoD Engine Efficiency Enhancement Technology
Abstract:The overall objective retrofits a set of production engines with D-Cycle technology, demonstrating in dynamometer testing, simultaneous improvements of at least 50% fuel efficiency increase, 100% boost in low-end torque, 15% reduction in engine-out emission. The heart of the D-Cycle engine is the innovative split-piston design that allows the exhaust and intake strokes to be independent of the crankshaft motion. This allows for flexibility to adapt to the load demand to maximize fuel efficiency, while boosting performance by producing a power stroke every revolution of the crankshaft while still performing 4 thermal cycles. The engine architecture remains the same with only modification to five components. Phase I focuses on computer modeling and optimization of the 4 thermodynamic cycles to provide the design constraints when performing the detailed design of engine components to be retrofitted. Phase II is the detailed design and build of the five components to be retrofitted into the engine. The retrofitted engine is tested on a dynamometer to assess performance, emissions and fuel economy performance compared to the original production surrogate engine.

Title:Advanced Burner for Field Kitchen Appliances
Abstract:The Marines and other military branches are seeking to develop more efficient, more reliable, and safer logistics fuel (JP-8) burners needed for field kitchen cooking appliances. Existing appliances that operate on logistics fuel have a number of significant shortcomings. In some cases, existing burners involve open flames which are inherently inefficient and vent both heat and potentially hazardous combustion products into the kitchen atmosphere. In other cases, the burners have low combustion efficiency, are relatively complex, and have a variety of reliability and maintenance issues. To improve efficiency, comfort, maintainability, reliability, and safety, on this project we will develop an advanced, fully enclosed, premixed JP-8 fuel burner technology that can be mated with a variety of field kitchen appliances, including tray ration heaters. This project will build on an ongoing Army burner development effort at Creare that is focused on griddles. In Phase I, we will adapt our burner technology to the tray ration heater application and develop a half-scale tray ration heater prototype. During Phase II, we will optimize the burner for a full-scale tray ration heater, develop a manufacturing design, and adapt the burner concept to other kitchen appliances.

Title:High-Efficiency Common Heat Source for Field Food Service Equipment
Abstract:The current common heat source for Marine Corps food service equipment is the Babington Airtronic burner, fielded first in the TRHS in 1996, and later in the M-59, FSU and EFK. A modern, highly fuel-efficient, common heat source is needed that can augment or replace the current burner system. The heat source, if fossil-fueled, is required to operate on logistic fuel (JP-8). TIAX has developed a patent-pending multi-fuel burner (which has already successfully operated with JP-8, DF-2, gasoline and propane) that has high-efficiency, low emissions, low parasitic power consumption, and is reliable and simple to maintain. The successful completion of Phase I will establish the feasibility and design of a high-efficiency burner heat source and mating hardware to be retrofitted to a TRHS. The Phase I effort will provide a foundation for Phase II development of a manufacturable prototype heat source and mating hardware. The successful completion of Phase II will result in a modern, high-efficiency, low-emissions, common heat source for existing Marine Corps food service equipment.

Title:Optical Aperture Gating for Single-pixel and Imaging LIDAR Systems
Abstract:Fast gating or shuttering of light through a large aperture is possible with a HOE (Holographic Optical Element) written into new novel materials such as, but not limited to, EO (Electro-Optic) polymers. These materials can be non-birefringent thin or thick films applied to an optical substrate of a square centimeter or larger. The refractive index of EO polymers can be switched fast (10 to 100 nanoseconds) by applying an electric field across the film, perpendicular to the plane of the optical substrate. Changes in refractive index can be up to a few percent which allow a holographic grating to accept or reject the light. These new novel materials are available from several research sources such as the University of Arizona and the University of Washington. These materials are currently being studied and tested as electro-optic polymer modulators with very small apertures (~1 mm) and operating at longer wavelengths than visable (e.g.1550nm). Gating non- collimated light can be accomplished with an additional HOE operating as a beam-shaping collimator. We plan to utilize existing holographic technology to build an optimised collimator for this project. Collected input light would first pass through the beam-shaping collimating HOE and then be gated with the EO-polymer-HOE. This would simultaneously meet FOV requirements and gating requirements.

Title:Optical Aperture Gating for Single-pixel and Imaging LIDAR Systems
Abstract:One of the key limitations in optical band underwater imaging and communications systems is the excessive attenuation and scattering light experiences in traversing the intervening media. Strong attenuation fuels the demand for high transmitter energy and high sensitivity (photon counting) detectors. Strong backscatter can temporarily blind or damage highly sensitive detectors, undermining the systems ability to sense (or communicate) over both short and long distances. In principle, the “backscatter problem” can be mitigated by employing high dynamic range detectors (i.e. a detector that is responsive to both high and low levels of photons). This requirement is often at odds with the sensitivity requirement of detecting a few photons/nanosecond. One potential solution is use a fast optical switch (or attenuator) in front of the detector to gate out the undesired near-field backscatter. Current technology cannot address all of the needs, such as polarization insensitivity, large aperture, and wide acceptance angle. Areté Associates has devised an elegant solution to this problem that promises to meet the demanding requirements in a compact, low power consumption open-architecture module. This program will result in the development of a stand-alone, polarization insensitive, fast optical attenuator module (10-100 ns) capable of achieving an off-on contrast of -30 dB over large physical (> 1 cm2) and angular (> +/- 10 degrees) apertures and with low insertion loss (< 2 dB).

Title:Ultrafast polarization independent optical aperture gating based on tunable photonic nanostructures
Abstract:The primary objective of this proposed project is to develop an ultrafast speed, polarization independent optical aperture gating device, which can be conveniently integrated into a high sensitivity photodetector so that the daytime performance of the LIDAR can be dramatically improved. To realize this goal, we will develop an innovative tunable photonic nanostructure, which can offer following unprecedented performances: (1) polarization independent operation, (2) less than 10 ns switching speed, (3) less than < 2 dB insertion loss, (4) OD 4 or better extinction ratio, (5) high out-of-band rejection, (6) large field of view (+/- 40 deg), (7) 1 KHz or higher repetition rate, and (8) compact size and small footprint. At the phase I stage, we will conduct both the theoretical and the experimental feasibility study of the proposed approach. A bench-top experimental system (with an aperture size 1 square millimeter or larger) will be fabricated and tested. At the phase II stage, we will collaborate with a major commercial partner in this field to develop a ready-to-use gating prototype device with an aperture size (1 square centimeter or larger) and integrate this device into a high sensitivity photodetector (e.g., a photomultiplier tube).

Title:Active Flight Control and Applique Inceptor Concepts for Autorotation Performance Enhancement
Abstract:Enhancing rotorcraft safety due to engine or drive train failures has been a primary concern throughout the history of vertical flight operations. Recent work on autorotation trajectory optimization has shown potential for improved flight control and guidance solutions, but work remains to implement these solutions without over-burdening the pilot during this high workload flight condition. With the recent trends toward active inceptors providing envelope limiting capabilities, it is desirable to investigate the application of these same methods to the autorotation recovery problem. Continuum Dynamics, Inc. and subcontractor Penn State University propose to develop and evaluate active flight control and appliqué inceptor concepts to enhance autorotation recovery performance and improve handling qualities for this challenging flight condition. The proposed research and development will focus on tactile cueing methods to provide pilot feedback commands for improving handling qualities while tracking optimal trajectories for a rotorcraft in autorotation conditions. Concepts for providing tactile cues will focus on active inceptors, including an appliqué concept based on smart material actuation for application in legacy aircraft. The Phase I program will include high-fidelity physics-based simulation evaluations in desktop and pilot-in-the-loop settings to identify promising flight control, guidance, and cueing concepts.

Title:Attaining Optimal Autorotative Profiles Using Active Inceptor Cueing
Abstract:As modern helicopters get heavier and their rotors get lighter, the odds of a successful outcome from an engine failure diminish. Previous research has demonstrated that for every point on the height velocity aircraft envelope there exists an optimal autorotative profile. While the optimal profile does not guarantee a successful landing, it does increase the chances of one. New England Analytics believes that through the use of active control inceptors, the aircraft can be flown to the optimal profile. The active inceptors will provide cues to the pilot indicating the required control inputs to achieve the optimal profile. To determine the optimal cues, NEA will conduct a survey of available tactile cues and assess those cues as to their functionality in assisting the pilot attain the optimum profile. The survey will look at tactile cues for use on both the collective and pitch cyclic. Additionally, NEA will examine the various inceptor configurations so as to ensure that the cues determined as optimal are effective across the various configurations. Finally, NEA will develop a conceptual tactile cueing design for the CH-53K.

Title:STI-TP-1119-Optimal Autorotative Profiles Using Active Inceptor Cueing
Abstract:Rotorcraft autorotation is a particularly challenging maneuver whose training demands are inadequately addressed in military or civilian aviation. Tactile safeguards may be one of the most effective means for protecting against control misapplication due to training gaps and negative training. In response to this topic’s solicitation STI proposes the Optimal Autorotation Cueing System (OACS). OACS takes its guidance from optimal aircraft trajectories and control commands computed with the direct-collocation optimization method, solved using a commercially available nonlinear programming problem solver. In Phase I an active cyclic will be used to demonstrate active inceptor feasibility during autorotation, while the collective inputs generated by the optimizer are issued directly to the helicopter simulator. OACS will offer both envelope protection as well as guidance control via the active cyclic. Cueing control law configurations will be demonstrated using human-in-the-loop flight simulation at the conclusion of the project.

Title:A Proposed Nitrogen Alloyed Stainless Steel With Innovative Thermal Processing For Superior Performance
Abstract:This Small Business Innovation Research Phase 1 proposal to the Department of Defense requests $80,000 support for Magna-Tech to demonstrate feasibility of a nitrogen martensitic stainless steel with high corrosion resistance and robust tribology performance.This proposal responds to Navy Topic Number NAVY 09-166, “Adjusted Nitrogen Alloyed Stainless Steel with Optimized Thermal Processing for Superior Balanced Performance”. Magna-Tech will synthesize three nitrogen martensitic stainless steel atomized powders containing various nitrogen content. These powders will be hot isostatically pressed to theoretical density and then carburized or nitrided to improve shear stability, and avoid adhesive wear and scuffing. Corrosion resistance will be enhanced through alloying additions, which will prevent reaction with corrosion inhibited oils. Phase I activities involve nitrogen gas atomization of the three innovative powder compositions, hot isostatic pressing to full density, and development of a thermal heat treatment to provide a tougher, more wear resistant core, while providing a hard martensitic surface that will have shear stability to resist adhesive wear and subsequent scuffing. Preliminary testing will be accomplished to demonstrate improvement in corrosion resistance, wear resistance and toughness of the core material.

Title:Adjusted Nitrogen Alloyed Stainless Steel with Optimized Thermal Processing for Superior Balanced Performance
Abstract:The materials used in Navy aircraft are prone to the harsh corrosive environment in which the aircraft operate. The corrosion protection of high performance bearing and gear steels without a decrease in mechanical and tribological properties is critical for Navy equipment readiness. Because of the insufficient corrosion resistance of current bearing and gear materials, the Navy developed corrosion inhibited oils for aircraft propulsion systems. The corrosion inhibitors in these oils limit their boundary lubrication (tribology) performance which limits the growth in power density needed for propulsion engine and gearbox systems. The purpose of this SBIR is to develop new high strength, corrosion resistant, wear resistant, scuffing resistant, rolling contact fatigue resistant stainless steels suitable for use in gears and bearings. These new steels are high chromium secondary hardening steels in which the secondary hardening response is enhanced by additions of cobalt and silicon. This SBIR will also utilize advanced surface modification techniques (i.e., low temperature carburizing and induction surface hardening) to further enhance the corrosion, mechanical and tribological properties of currently used bearing steels (e.g., Pyrowear 675, CX13VDW) and high nitrogen martensitic stainless steels (e.g., XD15NW) as well as the new ultra high strength stainless steels developed in this SBIR.

Title:Marine Mammal Mitigation Miniature Acoustic Detection Subsystem (MADS)
Abstract:Applied Physical Sciences Corp. proposes to develop a Marine Mammal Mitigation Miniature Acoustic Detection Subsystem (MADS) for the AN/SSQ-125 active source sonobuoy or similar system. MADS will consist of a miniature high-frequency active sonar array for detection and tracking of marine mammals within a nominal 300-m standoff distance from the high-power sonobuoy source. An initial design and performance predictions will be developed in the phase I base effort. A section of the receive array will be fabricated and tested in the phase I option. Phase II will demonstrate an autonomous detection system with a larger form factor and phase III will fully integrate MADS into the AN/SSQ-125 or other target sonobuoy. The designer and eventual manufacturer of the AN/SSQ-125, Ultra Electronics Undersea Sensor Systems, Inc., will provide support in phases I and II and is the phase III transition partner.

Title:Automated Marine Mammal Mitigation Sensor for Multi-Static Active ASW
Abstract:Based on its extensive experience designing, building, testing, and operating the High Frequency Marine Mammal Mitigation Sonar (HF/M3), the Integrated Marine Mammal Monitoring and Protection System (IMAPS), and the Swimmer Detection Sonar Network (SDSN), Scientific Solutions, Inc. proposes to develop a simple, compact, and low power active sonar for short-range detection, localization, and tracking of marine mammals. The requirement is for all the electronics and processing to integrate with an AN/SSQ-125 (A- size) sonobuoy. Preliminary analysis shows that a low source level of 173 dB re µPa2 @ 1 m should be possible while still achieving a range of 300 m and a bearing accuracy on the order of 10 degrees. The approached to be used is that of the SDSN system, simple fixed beams vice the use of a complex phased array system. The fine-bearing algorithm developed and proven for the SDSN will be used to determine bearing. In Phase 1 the feasibility of implementing the sonar will be assessed including integration with the AN/SSQ-125 source buoy. In Phase 2 a prototype of the mitigation sonar will be developed and tested at NUWC’s Lake Seneca test facility, using simulated marine mammal targets that SSI has already developed and tested.

Title:Automated Marine Mammal Mitigation Sensor for Multi-Static Active ASW
Abstract:Signal Systems Corporation, with its partners USSI and Marine Acoustics Inc, will show, using a simulation based design approach, that it is feasible to develop a highly automated Marine Mammal Mitigation Sonar (M3S), embedded in an AN/SSQ-125 source sonobuoy, which is effective in reducing operator workload while providing marine mammal mitigation to meet NAVAIR, OPNAV N45 requirements and the US government regulator (National Marine Fisheries Service) current standards. During the Phase I Option we will construct a breadboard of M3S and demonstrate its use in water. The SSC team has proposed a sound approach that comprehensively examines the entire set of risks associated with the M3S problem: sonar performance and development risk, regulatory approval risk, sonar automation in the presence of clutter, and achieving operator workload reduction. At the conclusion of Phase I, the SSC team will have a recommend M3S architecture, Key Performance Parameters that are needed for the final system, a simulation-based design assessment of the M3S performance with respect to these KPPs, conducted bench-top tests of the leading AN/SSQ-125 design changes, specifications for a prototype M3S in Phase II, briefing materials for regulatory review and a breadboard that will be tested.

Title:Target Localization Using Multi-Static Sonar with Drifting Sonobuoys
Abstract:Quick and accurate sonobuoy location is becoming more critical in the airborne ASW problem as multi-static search systems and data fusion techniques play more dominant roles. Sonobuoy locations must be determined quickly, and be constantly updated in order to estimate target locations as soon as target detection clues are available to the acoustic subsystem. Obsolete methods of buoy location such as “Mark-on-Top”, and systems based on the assumption that the target will be held in contact for significant periods, will not work. In Phase I, RDA proposes two techniques that can be used to locate sonobuoys by using only acoustic data from the drifting active and passive buoys, without the use of other data. These techniques can be used to locate both source and receiver sonobuoys. One method relies on the received incoherent Direct Blast / coherent ping, and one method uses internal buoy measurements. These techniques can be combined for more comprehensive and smaller positional error measurements. Initial software coding will be in Matlab for rapid development; this also allows extensive simulations for performance measurements. Definition of a transition path to Phase II and commercialization is part of the proposal.

Title:Target Localization Using Multi-Static Sonar with Drifting Sonobuoys
Abstract:A novel but proven sequential estimation method called Sequential Bound Estimation will be used to simulate the accuracy with which the relative locations of drifting buoys can be obtained using only sounds from coherent sources in current and upcoming ASW multistatic systems. The geometries for locating buoys, sources, and targets will be based in part on isodiachrons and isosigmachrons. We will demonstrate significant advantages of these novel methods compared with traditional approaches.

Title:Target Localization Using Multi-Static Sonar with Drifting Sonobuoys
Abstract:Future Air ASW will be conducted at higher altitudes, making visual, Mark-On-Top and RF techniques less accurate for receiver localization. What is needed are techniques that can provide buoy and target localization using just acoustic information. Alternatives such as installing GPS receivers in the sonobuoys suffer from either high cost or are easily jammed. Traditional acoustic stabilization techniques rely on the direct blast arrival information and can only update the relative geometry of the sensor field. Absolute positions depend on initial drop accuracy which at high altitude is going to be challenging. Field level ocean currents will also introduce errors that traditional acoustic buoy stabilization techniques cannot overcome. Signal Systems Corporation proposes to mature a new and innovative acoustic approach of buoy and target localization to provide absolute target geo-location without visual, RF or GPS inputs.

Title:Dual sensor system for global damage assessment in composite structures (GDACS)
Abstract:We propose a dual sensor system which supports in-flight global damage assessment in composite structures (GDACS) including air-frame superstructure and rotor blade assemblies. The system integrates in-flight structural health monitoring for impact damage detection (IDD) with flight-line deployment of an advanced laser vibration imaging (LVI) system for defect classification. The GDACS system comprises a sparse sensor array which, together with inverse signal analysis, identifies the location of impact loading events as they occur in-flight. A local damage evaluation (LVI) sensor is deployed to inspect identified high energy impact sites to assess and characterize the extent of damage. Together, these sensor systems provide a means for identifying potential damage events as they occur and categorizing damage severity to guide subsequent maintenance procedures. The historical data provided by the integrated system could thus provide a comprehensive framework for structural health monitoring and life-time air vehicle maintenance.

Title:Damage Detection of Composite Components using Surface Mounted Sensors
Abstract:Today’s advanced airborne weapons systems push the limits of technology to achieve greater speed, payload, and efficiency than previous generation systems. The tradeoff for the improved performance is that advanced systems and structures require extensive maintenance. Aurora proposes to develop an onboard health monitoring system that performs maintenance inspections with a high probability of detection (POD) without physical or visual access to the components to bring the cost of maintenance down on current and future air vehicles. Aurora will leverage its existing contract, the design and production of the CH-53K main rotor pylon, to select a CH-53K structure ideally suited to a structural health monitoring (SHM) system. Aurora’s familiarity with the design and analysis will aid in optimizing the sensor placement for maximum probability of detection and minimum weight impact. Panels will be fabricated with and without embedded manufacturing flaws and damage sites including micro cracks, delamination, and Barely Visible Impact Damage (BVID). The panels will demonstrate a SHM system based on the Metis Design Corporation surface mount Intelli-Connector SHM sensor. As a Phase 1 Option, varying numbers and locations of sensors will be used on the panel specimens in order to determine optimization parameters for sensor placement and density.

Title:Composite Airframe Damage Detection and Evaluation
Abstract:In composite structures, some of the most critical areas susceptible to damage are inaccessible due to assembly or manufacturing procedures. In order to scan or monitor the structural integrity on those zones, a multidisciplinary approach that involves smart materials, additive manufacture, embedded systems, and wireless communications among others is proposed. Thus, a piezoelectric transducer array is deposited or placed around the region of interest and used to interrogate, on-ground or in-flight, the state of the composite structure. Then, Lamb-wave tomography and acousto-ultrasonic techniques are used to identify and localize any damage.

Title:Life Usage and Health Assessment of Drivetrain Splines in Support of Condition Based Maintenance (CBM)
Abstract:Given the criticality of main- and tail-rotor spline couplings on rotorcrafts, there is a need for robust tools that will provide better design guidance, provide current health status as well as provide prognostic capabilities for spline couplings. To meet this need, Impact Technologies, LLC proposes to develop and demonstrate a spline health assessment and prognosis system that will utilize physics-based spline lifing models in conjunction with vibration data to produce actionable life usage and health assessment information. We intend to create a comprehensive technology suite that will accurately and quickly assess the impact of past and future vehicle usage on spline health status and therefore, provide the means of assessing mission readiness. The approach will consist of identifying and quantifying spline faults focusing on fretting-fatigue-induced crack initiation and subsequent crack propagation. Accurately characterizing the current health will allow improved estimates for remaining useful life. Development of spline health models will take into account physical material properties such as alloy composition, case hardness and surface finish in conjunction with local stress and displacement fields. As much as possible, current health state assessments will be made by leveraging existing on-board vibration sensors and utilizing novel data processing techniques.

Title:Vertically Aligned ZnO Nanowire Interleave for Enhanced Interlaminar Strength
Abstract:The proposed Phase I research effort will develop a novel technique to place vertically aligned ZnO nanowires in the interlaminar region of fiber reinforced composites. It is widely accepted that the interlaminar region of a composite presents one of the most challenging failure mechanisms to address. The aligned nanowires will be transferred to the tacky prepreg and used to provide out-of-plane reinforcement, crack bridging and control of the bond line thickness. The Co-PI recently demonstrated that ZnO nanowires grown on the surface of reinforcing fibers provided up to 3.5 times increase in interfacial strength while maintaining the fiber strength and increasing the composite strength. Based on our earlier findings we anticipate this technology will lead to significantly greater interlaminar strength while maintaining the in-plane properties. Our proposed methods are low cost, environmentally benign, compatible with prepreg processing, can be extended to a production-scale and do not require any advanced tooling or resin transfer processes. At the conclusion of the Phase 1 effort we will demonstrate the performance of the proposed technology and begin developing a commercial product. With the significant growth of the composites industry fueled by composite commercial aircraft we anticipate the resulting technology will have substantial commercialization potential.

Title:Enhancing Interlaminar Shear Strength in Helicopter Composites
Abstract:Luna Innovations Incorporated will investigate several approaches of including metallic fibers and vapor grown carbon fiber (VGCF) into glass fiber composites to improve mechanical properties including interlaminar shear strength (ILSS). The methods evaluated will minimally affect manufacturing processes anticipated for composite fabrication of helicopter components such as autoclave and RTM. For the VGCF, we plan to develop a thin film of VGCF that is included between primary reinforcing layers and disperses during the composite cure cycle. The metallic fibers approach will grow fibers in the Z direction of the composite to provide an increase in ILSS. Both of these approaches will be evaluated during the proposed Phase I effort using appropriate test specimens to determine effects on the ILSS as well as in-plane properties.

Title:Innovative Approaches for Enhancing Interlaminar Shear Strength of Two-Dimensional (2D) Composite Reinforced Flexbeams and Yokes
Abstract:This Phase I Small Business Innovative Research Program will develop and characterize a novel class of low-cost, lightweight hybrid composite materials that will enhance both the interlaminar shear strength and the high-cycle fatigue life of composite structures used for Navy rotorcraft applications, such as flexbeams and yokes. Performance Polymer Solutions Inc. will develop composite structures utilizing a patented Nanofiber Fused Microfiber (Nf2-M) approach, which produces a three-dimensional reinforcement microstructural architecture of multi-walled carbon nanotubes fused directly to primary reinforcing glass fibers. Incorporating Nf2-M hybrid material into these structures will enhance composite mechanical and thermal performance, thus increasing interlaminar shear strength and high-cycle fatigue life, without the addition of tooling or manufacturing process steps, all while maintaining the lightweight and low-cost characteristics of Navy rotorcraft systems.

Title:Air Textured S-Glass Rovings for Improved 2D Epoxy Laminate Interlaminar Properties(1001-435)
Abstract:Triton Systems Inc. along with program partner Fiberglass Industries Inc. of Amsterdam, NY propose to demonstrate the benefits of an air textured S-2 / S-Glass rovings for the improvement of 2D composite interlaminar properties. Improvement of interlaminar shear strength properties is a focal point for the Navy regarding 2D helicopter rotor hub laminates. Unidirectional hybrid composite constructions consisting of non-textured S-2 glass fiber combined with various percentages of air textured S-2 and S-Glass rovings will be produced to characterize the mechanical trade-offs between interlaminar and in- plane properties. This hybrid reinforcement design is intended to provide improved interlaminar composite properties (air textured roving) but with minimal reduction of in- plane mechanical properties (non textured roving). Air textured yarns are processed using continuous filament materials and introduce durable crimps, coils, loops or other filament distortions along the length of the roving. It is this feature that will promote physical entanglement with over and underlying plies and provide improved interlaminar strengths vs. typical 2D laminate constructions. This construction will be equally effective whether unidirectional, a 0o, 90o or in a quasi-isotropic lay-up.

Abstract:To address the Navy’s need for an energy transducer capable of powering an “A” size AN/SSQ-101 Air-Deployable Active Receiver (ADAR) sensor, Physical Optics Corporation (POC) proposes to develop a new Wave Energy Transducer (WET). This proposed device is based on harvesting the kinetic energy present in the undulating ocean surface using turbines. The energy supplied by the WET will be supplemented by high-efficiency solar photovoltaic systems. The innovations in turbine blade design and electromagnetic induction coil wiring configuration enable the WET to exceed the power requirements of the “A” size AN/SSQ-101 ADAR sensor and have the capacity to operate for years. As a result, this device offers more energy and has a longer life than existing devices, and can fit inside a small cylindrical volume

Title:Compact Energy Harvesting Power Supporting an
Abstract:Modern Air ASW operations are shifting to littoral areas typified by high ambient background levels, high reverberation and multipath, while targets are quieter than ever. One solution to retain the desired acoustic field performance in these challenging scenarios is to increase the sensor spatial density by deploying more sonobuoys. Unfortunately, these extra buoys have historically been used to reseed the field to extend the mission. Since ASW aircraft are limited both in overall numbers and payload, maximizing individual sonobuoy endurance is particularly desirable to extend field life. The current production version of the ADAR sonobuoy (AN/SSQ-101) falls short of the 8 hour endurance metric and operates 4.5 to 6 hours. The opportunity, then, is to extend the life of the ADAR sonobuoy by improving on the existing energy system. This can be accomplished through increased onboard energy storage as well as harvesting energy from the environment as it is available. These improvements must be implemented without affecting the system’s acoustic performance with minimal impact on the existing mechanical configuration of the buoy. SeaLandAire’s approach to address the energy deficit is to implement an ocean wave energy harvesting device in conjunction with an increased-capacity energy storage system.

Title:Dielectric Resonator Antenna
Abstract:Currently, naval aircraft are covered with many antennas for VHF/UHF LOS communications, UHF satellite communications, L-band and GPS functions. Some of these antennas are of the blade type whose bandwidths are difficult to extend and whose form factor can impact the flight characteristics of the aircraft. Other, low profile, designs are usually cavity-backed requiring significant hull penetration inside the aircraft. Dielectric Resonator Antennas (DRAs) provide a low profile and compact form factor as they can exploit the potential of high contrast materials and material gratings. Traditionally DRAs are designed for low loss, narrow band applications. So far reported bandwidths of DRAs have been up to mere 2:1 compared to 10: 1 or 100:1 bandwidths reported for other broadband antennas such as cavity-backed spirals. Applied EM along with its team members is proposing innovative concepts to substantially increase the bandwidth of DRA-type antennas. Indeed, our goal is to expand our current experience on cavity- backed antennas to DRA-type configurations. During Phase I, we will develop and demonstrate novel wideband DRA designs via full-wave numerical tools, with specific antennas to be optimized and constructed/tested in Phase II.

Title:Dielectric Resonator Antenna
Abstract:The objective of this proposal is to design and develop multimode dielectric resonator antennas (DRAs) operating in a wide frequency band from 30 MHz to 2 GHz covering VHF/UHF Line-of-site (LOS) communications, UHF Satellite communications, and L band including GPS frequencies. The DRA elements have many advantages such as wideband nature, small size, and high power capability as compared with microstrip antennas. The DRA is often made of high dielectric constant materials with very low loss tangent, which makes it attractive for high frequency applications where the conduction loss will be much smaller than for microstrip antennas. DRA elements are essentially lossless and have high radiation efficiency when appropriately excited. Thus, DRAs may be able to meet performance requirements at a lower power level, or may be able to even further improve performance due to their higher power handling capability. Because they are resonant antennas, however, their configuration must be carefully designed to achieve the desired bandwidth, polarization characteristics, and radiation patterns.

Title:Nondestructive Detection of Fiber Waviness in Laminates
Abstract:The Numerical Technology Company and North Star Imaging (NSI) team in this project to develop and verify a Computed Tomography (CT) based technology for accurate three- dimensional measurement and characterization of fiber waviness (wrinkles) in fiberglass/epoxy and carbon/epoxy composite structures. This team is supported by Bell Helicopter Textron who will provide the composite structures for the technology verification. The nondestructive evaluation (NDE) technology will enable: (a) ability to measure wrinkles and porosity in large structures and thick parts such as spars and yokes; and (b) automated three-dimensional wrinkle characterization. Wrinkles and porosity defects as well as their combinations contribute to structural failure. Ability to capture the shape of small wrinkles embedded deep inside a thick glass/epoxy structure as well as detect multiple wrinkles through the thickness will be verified. As wrinkle geometry and porosity distributions in the fatigue-critical composite parts are three- dimensional, accurate 3D measurement ability will be developed. The defect measurements will also converted into 3D finite element models for assessment of effects of the manufacturing defects on structural performance.

Abstract:Keystone is proposing a project to demonstrate the capability of using an alternate material system and additive manufacturing for the arresting tailhook component currently made from 4330V steel. Keystone is proposing to compete a non-corrosive high-strength nickel superalloy against a high strength stainless steel for use in the forged body of the tailhook component. Further, Keystone is proposing to fabricate the tailhook using an electron beam digital digital Manufacturing system to produce the machining preform of the tailhook. Keystone proposes to manufacture samples of both alloys to establish basic mechanical property mechanical properties and to facilitate a down selection between the two alloys. After down selection, Keystone will create shop drawings to be used in the optional task for producing a full scale tailhook. Finally, Keystone will also conduct a heat treatment optimization in the optional task to assure that the properties of the new tailhook match or exceed those of the current material.

Title:A Modified Vacuum Gas Carburizing Process To Improve Corrosion And Wear Resistance Of Nitrogen Martensitic Stainless Steels In Salt water Environments
Abstract:This small business Innovation Research Phase I proposal to the Department of Defense requests $80,000 for support for Magna-Tech P/M Labs to develop a carburizing process to optimize the corrosion resistance of nitrogen martensitic stainless steel. This proposal responds to Navy Topic Number NAVY 09-175 “Innovative Materials for Highly Loaded Wear Application in Arresting Gear Tailhook Components”. An additional $70,000 option to modify the thermal process to include carbonitriding of the surface would be requested. The thermal process will permit nitrogen martensitic stainless steels to sustain 200 hours in a marine environment while providing a wear resistant surface. Phase I activities include development of a low pressure vacuum carburization process to provide surface hardness of 58 HRC to a depth of 1 mm. The technology will prevent depletion of chromium from the grain boundaries of the steel, thereby improving the corrosion resistance. The process would be modified to permit nitriding as well as carburization as option. This adaptation would further improve corrosion resistance while providing improved surface wear resistance. A Phase II program would adapt the process developed to carburize prototype Navy arresting gear tailhook components, and establish a company to service military and commercial requirements.

Title:Innovative Materials for Highly Loaded Wear Application in Arresting Gear Tailhook Components
Abstract:The United States Navy (USN) currently uses a low-alloyed high strength steels, 4330V, for tailhook (shoe) applications. Unfortunately, there have been issues with the wear and thermal resistivity of 4330V that have led to short component lifetimes of 100-200 uses, as well as significant manufacturing waste and scrap losses due to discontinuities in coatings. In an ongoing Phase II SBIR program, QuesTek Innovations has developed a low-cost, high-strength, high-fracture-tough, SCC resistant alloy Ferrium® M54™ that could have a dramatic life improvement over 4330V and eliminate the need for a HVOF wear coating. In the Phase I program QuesTek plans to evaluate the wear resistance of the baseline alloy (4330V coated and uncoated) compared to Ferrium M54 to demonstrate the feasibility of eliminating the HVOF coating currently being used. In addition, high temperature tensile tests will be completed to demonstrate the superior high temperature resistance of M54 compared to 4330V. The Phase I program proposed herein details a plan to demonstrate the feasibility of replacement of the 4330V alloy with M54 based on improved wear resistance, thermal resistance, and resistance to stress corrosion cracking while eliminating the need for HVOF coatings.

Title:Wire Restraint Devices
Abstract:Wiring restraint devices used on all DOD aircraft are limited to polyester tying tape and plastic cable straps. They are applied at set intervals along the cabling to constrain the wire elements into a discrete, tight bundle, thereby minimizing its vulnerability to various types of damage. However, these methods are problematic in at least one of the following ways: they can be difficult to apply, constrain the cable too loosely or tightly, fail in various ways, generate foreign object damage, and lack suitability for areas with challenging environmental requirements. Innovative Dynamics proposes to develop an alternative method based on the use of advanced tape-like but non-adhesive, self-fusing silicone material. The successful implementation of this method will culminate with the development of the material, application techniques, and a specialized application tool to apply it to cabling for wide use in either factory harness assemblies or in-situ aircraft installations.

Abstract:Aircraft wiring system problems account for approximately 1 million man-hours of maintenance repair annually across the US Navy Fleet. In addition to the cost, the Navy estimates that 2.5 electrical fires occur in Navy aircraft every month, putting Naval aircrews and support personnel at serious risk. A contributing factor to these wiring problems stems from failure of the existing wire restraint devices. The two most common wire restraint devices in use today are the tying tape and the plastic ties. Prototype Productions, Inc.

Title:Advanced Lossless Inter-channel Data Compression with Enhanced TCP/IP Capability
Abstract:Due to the rapid advancement of automation level for Navy’s vessels and the staggering data volume generated by advanced sensors/instrumentations, the U.S. Navy is seeking advanced data compression algorithm and bandwidth utilization mechanism that will enable very large amounts of data to be transmitted in bandwidth-limited scenarios from ship to shore. In order to meet the Navy’s design requirements, Broadata Communications, Inc. (BCI) proposes an Advanced Lossless Inter-channel Data Compression with Enhanced TCP/IP (ADET) capability, based on our extensive experience in data processing, compression, and bandwidth efficient transmissions. The proposed ADET efficiently integrates our two novel innovations—highly efficient lossless inter-channel compression and bandwidth efficient TCP/IP—into an offload engine. This engine not only achieves superior compression performance but also provides robust and bandwidth- efficient data delivery over dynamic and bandwidth-limited tactical networks. Based on our novel innovations, both the compression ratio and transport operation can be adaptively adjusted, based on intelligent network measurements. The ADET system, which easily works independent of underlying network conditions, can fulfill the Navy’s goals. In addition, it can provide numerous commercial benefits.

Title:ALPACA, Adaptive Learned Priority Anytime Coding Algorithm
Abstract:Future aircraft carriers will rely increasingly on automation as manning levels continue to decline, and opportunities are identified for “smart” automation. One particular area with great potential is in the health monitoring and diagnostics of aircraft launch and recovery equipment, through reachback to on-shore services. A key technical hurdle in realizing this capability is achieving adequate data compression to accommodate low- and variable-bandwidth channels: existing compression algorithms simply do not meet the challenge because they are either lossless, and therefore not adaptive to low bandwidth, or are based on perceptual models, and not necessarily relevant to diagnostic tasks. However, by “learning” the relevance of on-board data to the on-shore diagnostic task, we can prioritize the most relevant information to be transmitted quickly, with more complete data to follow. We also develop anytime codes to address adapting to bandwidth. We propose ALPACA, Adaptive Learned Priority Anytime Coding Algorithm, which combines a distortion function learned from the on-board data to prioritize information in the encoding, with anytime coding, a novel technique for sending a message that can be reliably decoded if truncated.

Title:MAXTHAL®: A Novel Material for Lightweight, High-Temperature, Low-Cost, Non-Rotating Turbine Engine Components
Abstract:MAXTHAL®-211 is a lightweight, machinable, oxidation resistant, easy to fabricate and low-cost material to be evaluated for components that are of complex shape and capable of surviving 1200 ºC (2200 F) or greater as required for hot-section non-rotating turbine engine applications. MAXTHAL®-211 is a derivative of Ti2AlC where the chemistry is modified (proprietary) and fine alumina particles are dispersed at the grain boundaries to improve the high temperature strength and creep resistance. It can be easily formed into complex shapes either by conventional machining or by net-shape fabrication methods such as injection molding or slip casting followed by pressureless sintering. With a density of 4.0 g/cm3, MAXTHAL-211 is lighter than Titanium. It has an operating temperature of 1400 ºC in air due to the formation of protective Al2O3 layer. The material has outstanding thermal shock resistance and damage tolerance. MAXTHAL®-211 can operate at 1400ºC for more than 5,000 h. Preliminary results also show significant improvement in compressive strength at 1200ºC. We propose to optimize the composition to reach the target 500h stress rupture of 50 MPa at 1200ºC while maintaining the manufacturability and oxidation resistance.

Title:Innovative Concepts for Lightweight, Low-Cost, High Temperature Turbine Components
Abstract:Carbide composites of carbon and Group IV metals (Ti, Zr, Hf) will be developed for high temperature turbine components. Material will be fabricated from a metal and graphite fragment feedstock through a single step melt-casting process, providing near net shape components. Carbon content will be a controlled variable, taking advantage of the solubility of carbon in molten Group IV carbides. Hypereutectic carbides, upon solidification, precipitate highly oriented graphite flakes within the eutectic structure. These flakes provide advantages in thermal and mechanical properties with significantly reduced density. For titanium-carbon (TiC-C), it is useful to a temperature >2000 °C, the density reduced from 4.93 g/cc in the stoichiometric to about 4.0 g/cc which reduces mass relative to super alloys. In an elevated temperature oxidizing environment, a stable metal oxide coating forms in situ on Group IV carbides that inhibits degradation and contributes to excellent dimensional stability. Compared to other processes for CMC fabrication, single step casting to a near net component is expected to reduce both cost and fabrication time. The effort will emphasize the fabrication of TiC-C samples and measurement of properties critical for systems use. Phase 2 will provide full size TiC-C turbine components for evaluation by System Contractors.

Title:New advanced LINTERTITANIUM-5 technology for creation of highly-durable ultra-high heat protective diffusion coatings for superior protection of Ti6Al
Abstract:Objective of this topic is development of custom LINTERTITANIUM-5™ technology for creation of inexpensive ultra-high temperature (UHT) wear, erosion, corrosion and oxidation resistant diffusion surface layers on light-weight Ti, Zr and Nb-based alloys to be used in manufacturing of aero-turbine engine components. SANOVA proposes creation of such surface layers using SANOVA’s new patented thermo-chemical treatment technologies LINTERPROCESS™ and LINHEAT™. SANOVA has conducted preliminary experiments on Ti6Al4V alloy and achieved extremely promising results. Phase I effort will be concentrated on further research in creation of super-carbides or nitrides on surface of Ti6Al4V using SANOVA treatment technologies. Special specimens will be created and processed with various treatment protocols on existing and effective laboratory equipment. Treatment parameters, such as processing cycles, active medium composition and processing temperatures will be iteratively applied and optimized for best material properties. Resulting process will be able to rapidly, consistently and inexpensively create highly-durable light-weight UHT (above 5000°F) protective diffusion layer with extremely high wear, erosion, oxidation, and corrosion resistance on a surface of any Ti6Al4V component. This research will be continued in Phase II on other Ti alloys and include Zr and Nb alloys to generate optimal light-weight UHT materials which meet and likely exceed Navy requirements.

Title:Marking System for Ceramic Matrix Composites
Abstract:Physical Sciences Inc. (PSI) proposes a method for marking for ceramic matrix composite (CMC) components. The method utilizes ceramic phosphors embedded within the top ply of a fabric reinforced material. The method enables high resolution markings to be written directly into components during early stage manufacturing. The optically activated phosphors can be read by production line and field personnel using a commercially available radiation source and will not degrade as a result of composite manufacturing practices or anticipated operating environments. During Phase I PSI will demonstrate the ability of the method to mark CMCs with high resolution markings and show that the markings are readable after CMC processing. Further, we will show that the marking method is robust to the anticipated operation environment and does not reduce the mechanical strength of the composite compared to the as-fabricated, unmarked material.

Title:Ceramic Matrix Composite Parts Marking
Abstract:Ceramic matrix composites (CMCs) are increasingly being considered for a variety of hot structure applications, both military and commercial use. CMCs offer improvements in durability, higher temperature capability and reduced weight. Rapid, reliable, and cost effective parts marking technology is necessary for in-process tracking and parts flow optimization, but the process is complicated for CMCs, given the high temperature exposures they are subject to during processing and in service. Ex One proposes to use short pulse laser technologies for the installation of Item Unique Identification (IUID) features on CMC components. The goal of the program is to develop a technique which is rapid, low cost, automated, and allows for automated scanning. Both picosecond and femtosecond laser marking technologies will be evaluated. Ex One will conduct picosecond marking tests and will team with Raydiance, a femtosecond laser manufacturer, for marking tests using femtosecond lasers. Additional team members include Rolls-Royce for application specific information relative to CMC components and ATK as a manufacturer of CMC materials and components. The team will provide an analysis of the manufacturing and utilization of CMC materials, two regimes of short pulse laser technology, parts marking expertise and evaluation of material properties following the marking process.

Title:Corrosion Resistant Non-Toxic Coatings for High-Strength Arresting Gear Tailhook Components
Abstract:The principal aim of this program is to develop non-toxic corrosion resistant coatings to replace cadmium for tailhook applications on the Joint Strike Fighter (JSF). These coatings need to be dense, effective at preventing corrosion of the alloy, and able to be deposited onto non line-of-sight areas. Coating compositions will be aluminum based alloys which have previously been demonstrated on steel substrates using Directed Vapor Deposition (DVD). The aluminum based DVD deposited coatings have previously demonstrated corrosion resistance, are dense with no porosity, have a relatively low modulus to promote coating adhesion, and importantly can be deposited onto non line-of-sight areas. Coating compositions will be optimized to the current tailhook alloy. Corrosion testing will be performed in accordance with the “High-Strength Steel Joint Test Protocol.” Successful demonstration of the corrosion protection during the Phase I effort will lead to a Phase II effort that would include additional qualification testing as well as the coating of components utilizing DVTI’s production scale coater. A significant outcome of this study is the establishment of non-toxic corrosion resistant coatings and coating processes that provide the required corrosion resistance while reducing the usage and exposure to toxic materials.

Title:Non-Toxic, Corrosion-Resistant Amorphous Coatings for Protection of Steel Tailhook Components
Abstract:The U.S. Navy desires the replacement of cadmium (Cd) platings for the protection of high-strength 4330V steel employed in arresting-gear tailhook components. While Cd is a protective coating, it is not environmentally-friendly. As an alternative, Engineered Coatings (ECI) and Southwest Research Institute (SwRI) propose a two-tier approach: 1) higher-risk atmospheric-plasma chemical vapor deposition of amorphous Al-alloy coatings (ECI) and 2) lower-risk ion-beam assisted deposition (IBAD) of amorphous Al-alloy coatings (SwRI). The higher risk approach is a non-vacuum process, which simplifies component handling, while the second process has produced coatings with improved corrosion protection over pure Alcad surfaces on Al, Ti, and steel surfaces. Both processes are inherently non-toxic, as vapor-phase and gaseous effluents are generated for the AP-CVD process and solid particulate waste is generated for the IBAD process. Our team proposes to develop processing parameters to deposit thick amorphous Al-alloy coatings and perform a systematic testing protocol, using a subset of the recommended Boeing/CTC test protocol for steel landing gear components. This will include composition/structure determination, bend-adhesion, salt-fog exposures, and galvanic-coupling measurements. In the Phase I option, we will develop fixturing and translation methods to enable uniform coverage of the complex tailhook geometry and develop a preliminary M&P specification.

Title:Thrust Estimation System for Military Engine Test Cell Applications
Abstract:Engine thrust is a critical measurement in military engine acceptance tests, and this measurement may be too noisy or to extract meaningful information. Impact Technologies therefore proposes to develop an accurate real-time military engine thrust estimator to compute “virtual measurements” of engine thrust and other parameters of interest in a streaming, on-line fashion. Thrust estimation is a challenging task due to the complex dependency of thrust on the engine’s health condition and other unknown factors. To accurately capture engine-to-engine variation and engine degradation, a hybrid model is proposed that consists of a physics-based model and an empirical model based on Artificial Neural Networks (ANNs). The model will be used within a Kalman filter estimator structure reconstruct the true dynamic engine performance variables. This scheme will be enhanced by a sensor validation scheme to ensure robustness to sensor faults or noise that can occur in the test cell environment. The proposed Phase I is designed to establish a sound proof-of-concept capability with high prospects for maturation in DoD/commercial engine test cells and on-wing engine applications.

Title:Low-Cost, Compact, Multi Directional Low Airspeed Indicator for Rotary Wing Aircraft
Abstract:The War on Terror has produced new, asymmetric warfare threats — ever-more- sophisticated explosive mines on land and at sea. The Navy has moved to incorporate mine counter measures (MCM) into an organic approach where combat units themselves handle counter-mine assets and perform their functions as part of an ongoing military operation. The Navy’s organic airborne MCM platform, the MH-60S, hosts several airborne MCM systems, two of which are towed mine-hunting and sweeping systems. These systems require that the MH-60S fly low and slow to maintain the search pattern. It is challenging to maintain track and control with the lack of geographic markers and the effect of local winds on the air vehicle path. The provision of multi-direction low airspeed indicators would decrease the pilot workload and improve the performance in continuous, low-speed missions. Ophir proposes to leverage our previous work with airspeed laser radars to develop a small size, weight and power, low cost, and eye-safe system. This sensor is capable of providing range-resolved, profiles of multi-directional airspeed for the full 360° field of regard around the air vehicle in “clean”, undisturbed air, outside of the rotor wash. This airspeed information will be conveyed through simple representation on the pilot’s control panel.

Title:Rotorcraft Airspeed Measurement System
Abstract:To address the Navy need, Physical Optics Corporation (POC) proposes to develop a new Rotorcraft Airspeed Measurement (RAM) system. This proposed system is based on self-mixing interference in a semiconductor laser diode. The innovation in using low- power, small-sized diode lasers and in assembling diode lasers in a specific geometry coupled with a wavelength modulation technique enables the proposed system for the accurate measurement of multi-directional low airspeed of a helicopter in low altitude operations over water or ground. The RAM system combines its three-component wind speed data and the orientation and ground speed data of the helicopter from embedded Global Positioning/Inertial navigation devices to calculate the true airspeed of the rotorcraft. The proposed system will be capable of measuring airspeed in the range between 0.5 ft/sec and 1500 ft/sec. In Phase I, POC will demonstrate the feasibility of the RAM system with a velocity measuring module using a simulated rotor wash environment to measure multi-directional airspeed of a model rotorcraft in laboratory. In Phase II, POC plans to develop a rotorcraft-deployable RAM prototype to be installed and tested in a Navy helicopter or similar platform recommended by the Navy.

Title:Stand-Off Laser Airspeed Sensor (SOLAS)
Abstract:Real-time knowledge of accurate helicopter airspeed enhances crew situational awareness and reduces pilot workload in MH-60S Airborne Mine Counter Measure (AMCM) operations. However, conventional pitot-static indicators are not accurate in low speed flight due to local effects of turbulent rotor wash. Physical Sciences Inc. (PSI) with subsidiary, Q-Peak, Inc. (Q-Peak) proposes a powerful new enabling technology for wind/airspeed monitoring using a small, ruggedized on-board coherent wind LIDAR (Light Detection and Ranging). The “Stand-Off Laser Airspeed Sensor” (SOLAS) uses a compact laser scanner to detect all-direction airspeed using laminar wind data from outside of the rotor wash zone. SOLAS is based on a novel laser transmitter/receiver architecture with optimized temperature, vibration, and frequency stability for military applications. The cost and complexity of SOLAS is minimized using “passive Q-switch” and “fiber delay line” techniques developed by Q-Peak. The laser has no moving parts, liquids, or disposable elements. The scanner can be easily clamp-mounted as part of the CSTRS rack system, or eventually integrated into the MH-60S airframe in a similar manner as the current pitot-static sensor head. Airspeed data is processed aboard SOLAS for output to glass cockpit or other display systems in real-time.

Title:High-Reliability Gas-Bearings for Military Air Cycle Machines
Abstract:Air cycle machines (ACM) are critical components that provide refrigeration in military and commercial aircraft. These systems extract bleed air from the aircraft’s engines or an auxiliary power unit, and refrigerate it for cooling the environment or electronics. Currently, ACMs utilize hydrodynamic foil-bearings to support the expansion turbine at high operating speeds. These bearings have exhibit premature degradation or failure due to contamination and bearing overload. Creare’s proposed approach is an advanced oil- free bearing system that meets both high-load capacity and high-reliability requirements for demanding ACM systems by: (1) eliminating start-up and shut-down preload forces, (2) utilizing hard-coatings on the bearing surfaces, and (3) implementing an active contamination mitigation system. The bearing concept has heritage from our high reliability turbomachines for long-duration space missions. During the Phase I project, we will demonstrate feasibility of our innovation for ACM applications through load and contamination tolerance testing on the journal bearings. Once feasibility is established, we will begin extending the system to ACM thrust bearings during the Option Phase. During Phase II, we will implement our bearing technology into an F 18 ACM platform and demonstrate the load capacity and reliability of our system in an operational ACM.

Abstract:In the proposed project, Integran USA seeks to demonstrate that both hard and lubricious second-phase particles can be codeposited within a tough, nanocrystalline cobalt-based metal matrix binder using a cost-effective manufacturing process to produce coatings with a low coefficient of friction and a high resistance to abrasive wear and contamination for use on air foil bearing contact surfaces. Proposed here is an innovative and cost-effective manufacturing process capable of producing nanocrystalline cobalt- based metal matrix composite surface coatings as solid lubricants for high temperature, high speed bearing applications. A materials technology optimization and evaluation program is proposed, based upon previous proprietary developments by the applicants in the area of cost-effective production of electrodeposited metals, alloys and composites with nanocrystalline microstructures. The proposed program seeks to develop a metal matrix composite coating, consisting of a nanocrystalline cobalt-based metal alloy matrix incorporating both hard second phase particles and lubricious second-phase particles to provide a high strength, highly wear/erosion resistant and highly lubricious coating that can meet all requirements for solid lubrication of air foil bearings. Phase I activities will demonstrate the performance enhancement of the nanocrystalline metal matrix composite coatings through a series of coupon tests evaluating morphology, wear, friction, hardness, corrosion, surface roughness, adhesion and fatigue.

Title:Innovative Bearing Concepts For High Speed Rotating Machines
Abstract:Under Phase I, MiTi will first review existing Navy data and materials to more thoroughly define the potential Air Cycle Machine foil bearing failure modes including different potential contaminants and overload conditions. This data will be used to prepare preliminary designs of MiTi’s novel sealed, high capacity thrust and journal foil bearings as direct replacements for the existing bearings. In the Phase I option, a selected MiTi test rig will be modified as needed to conduct baseline contamination verification testing. The Phase I option will use the existing ACM foil bearing design for testing under both dry particle debris and “wet oil/sea water condensate/fuel” contamination conditions in order to simulate the failure mode(s) being experienced and establish a baseline for Phase II. Under Phase II, the preliminary MiTi sealed bearing designs will be updated and fabricated; a dynamic simulator and the actual ACM will be tested with baseline and newly designed bearings under contamination and vibration overload environments to demonstrate improvements achieved with the novel MiTi bearings. Phase III will lead to complete qualification and certification of the developed bearing concepts so that they may be transitioned to F-18 and other high speed machinery applications.

Abstract:Prime Research, LC proposes a novel fiber optic sensor for measuring pressure in gas turbine engines at temperatures up to 2900°F.. The micro-fabricated monolithic transducer capitalizes on a highly sensitive mechanical resonance transduction technique. These optically interrogated sensors will output an inherently digital signal which is immune to EMI and electronics drift. Monolithic construction of these transducers from high- temperature ceramics and optical interrogation using single-crystal sapphire fiber will result in an accurate and robust transducer for harsh environments. Successful development of this technology will enable new measurements in turbine engine hot sections, hypersonic flows, combustion processes, and other extreme environments where pressure measurements are currently not possible.

A Ka-Band radar system offers the resolution required to determine safe landing and takeoff conditions as well as a package size that can be incorporated within the weight and size constraints of military and commercial helicopter platforms. An electronically scanned phased array is the ideal choice for the above requirement from rapid scanning, lower profile, and reliability standpoint. Historically, cost of a Ka-band phased array for radar applications has limited the use of electronically scanned antennas.

The Phase I approach is to research and identify a reliable and effective sensor suite, extend algorithms for safer and more effective VERTREP operations, and develop a conceptual design that includes a user-friendly interface for the air crews. The developmental tasks are challenging in that the sensor suite must identify landing areas and evaluate them on the constantly moving surface of a ship at sea.

Title:Innovative manufacturing processes and materials for affordable Transmit/Receive (T/R) module Production
Abstract:GVD Corporation (GVD) proposes to develop low-cost, conformal, board-level environmental coatings for phased array radar T/R module boards. These boards must survive harsh environmental conditions for long periods, such as humidity, bias, temperature cycling, and ionic contamination. Such conditions can cause delamination and migration of the boards’ metallic interconnects. Water absorption by the boards can change their RF performance. Conventional hermetic packaging for T/R modules is bulky and costly, and low-cost non-hermetic coatings are preferable. In an effort to reduce or eliminate adverse environmental effects, GVD will develop its solvent-free, polytetrafluoroethylene coating (PTFE) coating as an alternative candidate for board encapsulation. PTFE is an ideal material for this application, possessing both low dielectric constant and hydrophobicity for water-shedding. Unlike conventional PTFE coatings, GVD’s PTFE coatings require no post-processing (e.g., high-temperature sintering), and are immediately ready to use. In Phase I, GVD will screen multiple PTFE coating formulations using tests designed to simulate environmental exposure. Promising coatings will be downselected for RF testing and coating of T/R module boards. The most promising coatings will then be further developed in Phase II with an eye toward coating scale-up and manufacturing.

Title:Smart Multimodal Image Registration and Fusion (SMIRF)
Abstract:To increase all-weather, visual search capabilities, modern submarine surface imaging systems have installed several different modality cameras in the periscope or photonic mast. The current system displays each sensor modality independently, where the operator must decide which modality is optimal for which environment, and must constantly switch between modalities to search for critical information. 21st Century Systems, Incorporated is pleased to propose SMIRF (Smart Multimodal Image Registration and Fusion technology). SMIRF will produce a higher contrast resultant image through fusion of multiple sensor modalities while reducing image clutter from maritime environments. SMIRF’s key innovations include the use of spatial, temporal and cross- modality information to meaningfully identify salient versus non-salient corresponding regions within each image modality. Information quality statistics from each region are then used to dynamically decide for each local region which fusion strategy available within the data-fusion module is optimal. An adaptive approach allows SMIRF to intelligently choose “the right tools for each job.” With our extensive experience in video analysis products and with a 100th percentile SBIR commercialization rating, we are just the company to deliver this capability so submarine commanders can focus on seeing what’s in the area and not on which setting to use.

Title:Image Fusion for Submarine Imaging Systems
Abstract:Areté Associates proposes development of an automatic image fusion capability that provides superior scene content than any of its spectral components with less operator workload. To do so we will focus on overcoming the challenges of registration (spatial and temporal) and noise in the fused result. We will heavily leverage (a) proven registration algorithms in our real-time software package AGILE; and (b) advanced experience in noise reduction, physical modeling, and robust image fusion with layering techniques.

Title:Distributed Smart Control and Health Management Framework for Next Generation Electric Ships
Abstract:Intelligent Automation Inc (IAI) is teaming with subject matter expert Prof. Sudip Mazumder from the University of Illinois, Chicago (UIC) to propose a novel, clean, distributed, wireless, control framework for the Next generation all-electric ship. The primary innovation of this proposal is the synergy achieved by combination of software intelligent agents for decentralized reasoning, with advanced control algorithms. IAI team will also leverage the work being done in their NAVAIR, AFRL, ONR, and NSF projects to develop embedded, active probing sensors, and COTS rapid response SiC based sensors and actuators for the Naval power systems. A decentralized Agents based power system over a wireless network fits the Navy’s vision to build distributed control systems (DCS) along with system wide health management to ensure system survivability and robustness. The proposed distributed agents based system will provide the capability to monitor and adjust energy generation, energy storage, and system loads for enhanced shipboard performance and health. While the proposed system would work seamlessly with highly-efficient next generation energy generation concepts; it would also be backward compatible to retrofit on existing fleet. IAI will work with Northrop Grumman Ship Systems (NGSS) to transition our technology beyond phase I and II.

Title:A Market-Based Approach to Optimal Power Allocation in Electric Warships
Abstract:The proposed work will investigate the feasibility of a market-based power allocation method for shipboard power systems. These systems will encompass more loads demanding more power in order to meet the U.S. Navy’s current and future missions. As power is a scarce resource with alternative uses, the allocation of power within a shipboard power system is posed as an economic problem. As such, PC Krause and Associates proposes to address power allocation with an artificial free market. The equilibrium points reached by free markets can be shown to be efficient in the sense that no market actor can have more without another having less. Thus, if the market actors (in this case, generation, distribution, conversion, storage, and usage devices that comprise the shipboard power system) each act according to microeconomic principles, an efficient solution emerges. The proposed work will frame the economic goals of the actors such that the efficient solution arrived at by the market corresponds to a solution that maximizes the utility of the commanding officer of the vessel. In this way, defining objectives is the only necessary human input, and the artificial market automatically controls individual devices, thereby finding the most efficient method of attaining the objectives.

Title:A Novel Power Chip for Opportunistic Energy Harvesting on Submarines
Abstract:Our objective is to develop a novel, MEMS-based, durable power harvesting chip that is capable of gathering, converting and storing multiple natural energy sources, including optical and thermal radiation, microwave and millimeter electromagnetic waves, and vibrations, into usable electrical energy capable of operating low power electronic devices, especially wireless sensor systems on a submarine. This solution offers several advantages over the existing methodologies of electromagnetic energy harvesting, including: multiple energy sources, operational in various environments, higher energy conversion, easy rectification, high power output to volume ratio, and compatibility with standard microfabrication techniques. In Phase I, we will focus on analysis, design and testing the components of the power chip and experimental validation of the feasibility to harvest ambient energies adaptable to a wireless sensor solution in the laboratory. In addition, we will evaluate reliability and operational protocol for the proposed power chip. In Phase II, we will optimize and fabricate the device developed in Phase I, followed by a demonstration of energy harvesting in a representative environment using a scaled prototype. The power device will be integrated with an energy storage system that is suitable for sensor operation. Finally we will demonstrate performance against established parameters in a representative environment.

Title:Opportunistic Energy Harvesting for Submarine Wireless Sensors
Abstract:KCF Technologies is proposing to leverage our leadership in power harvesting to develop magnetic field harvesting devices for submarine wireless sensors. The project responds to a Navy opportunity for reducing sensor maintenance and installation cost by providing enabling technology for eliminating hardwiring. The magnetic field generated by degaussing coils offers a unique opportunity to harvest power to operate wireless sensors that would otherwise be infeasible or require large batteries. In the proposed research work powering sensor nodes autonomously for acquiring and transmitting sensor measurements will be investigated. The primary harvester design objective will focus on harvesting and delivering a continuous power of 100 mW to a sensor load in a package size of two D-cell batteries. In Phase I, KCF will build and bench-test a magnetic field power harvester based on an analysis of the broadband magnetic energy available on a submarine. A through design study of an optimal magnetic harvester design and the associated power electronics for extracting and storing energy will be completed. An assessment of the harvester system feasibility will be based on design studies and prototype hardware performance.

Title:Multi-Material Structures
Abstract:Composite materials are prime candidates for use in the design of US Navy non-pressure and control surfaces for submarines and topside and mast structure for surface ships. These materials offer the advantage of increased specific modulus and strength as compared to the traditional metallic options. Further, composite materials offer the ability to tailor the strength and stiffness of the structure through selected use and placement of alternative reinforcements within a specific lay-up. This effort investigates alternative approaches to tailoring the transition between two or more different materials, meeting the strength and stiffness performance requirements, while minimizing galvanic corrosion. The investigation of alternative approaches takes on various levels of consideration: global structural and non-structural assessment; micro-mechanics analysis for strain compatibility; galvanic corrosion between multi-material connection configurations; and material compatibility between the resin matrix and the alternative reinforcements.

Title:Multi-Material Structures (MSC P9044)
Abstract:Minimizing corrosion is a constant challenge to the ship design community. Fiber- reinforced polymers are generally corrosion resistant; in fact glass fiber reinforced composites may be fastened or joined with almost any fastener material to metals without fear of galvanic corrosion. However, carbon fiber reinforced composites, which may be necessary to achieve strength and stiffness performance goals, can induce galvanic corrosion in the attached metal structures, or metal fasteners. In this proposal, Materials Sciences Corporation presents a combined analytical and experimental plan for demonstrating the performance potential of hybrid composite structural components of interest to the undersea Navy. Here, the term hybrid is used to describe a composite manufactured using both carbon and glass fibers, either in general layered configurations or discrete transition areas of a structural component. Two important technical issues will be addressed for two out-of-autoclave material processing systems of interest to the U.S. Navy; viz., evaluation of processing induced stresses due to dissimilar material stiffnesses and selection of lamination architectures that provide the best balance of strength and durability. Coupon level tests will be conducted to validate translation of individual material properties to hybrid laminates and provide guidance for scale-up to more complex subcomponents in Phase II.

Title:COUNTER: Contermeasures for Opposing Undersea Naval Threats and Emergency Response
Abstract:Current combat control systems require human manipulation that may unnecessarily draw the attention of the Commanding Officer (CO) and his team from more pressing matters such as damage control and re-engaging the enemy. There is no automatic method of selecting countermeasures and the CO must rely on crew actions, mental calculations, and approximations without the benefit of automated systems or processes. Addressing these concerns, the Aptima Team proposes to develop COUNTER (Countermeasures for Opposing Undersea Naval Threats and Emergency Response). COUNTER enables efficient and intuitive interaction with the command team to facilitate informed and timely decision making. Rigorous information flow modeling is used to provide a detailed mapping of the tasks and constraints that the CO uses to mentally integrate, identify, and execute countermeasures. The information flow models are integrated with dynamic decision aid algorithms to assist the CO in determining the best course of action during high-stress and time-critical hostile events. COUNTER also uses the information flow model to integrate the results of the decision aid algorithm, using an efficient interface that ensures that the CO receives the right information at the right time.

Title:Real-time decision aid for enhancing ship’s self-defense
Abstract:Our proposed Defensive Engagement System (DES) is designed to provide the submarine decision maker with automated actions, decision aids, and workflow cues to maximize the effectiveness of defensive actions when they are required. The DES encompasses automated defensive payload assignments, automated and optimized presets, evasion planning with options, rapid counter fire capability, and other defensive actions aids to provide enhanced situational awareness. The DES is designed to operate as a background function so that it is always engaged and current plans and recommendations can be reviewed during the watch routine. Our DES is also designed as both a forward fit and back fit capability. Leveraging our Combat System of the Future architecture, the forward fit application is designed as a service for a Service Oriented Architecture (SOA) implementation. For the back fit requirements, a translation layer will be used to provide similar functionality for current architecture configurations. The proposed DES, takes a layered defensive strategy by providing sensor cueing for early assessments of transients or other energy detections of interest. With the sensor to display approach, defensive aids and recommendations can provide the best available guidance on the required accelerated defensive decision time line.

Title:Real-time decision aid for enhancing ship’s self-defense
Abstract:This report describes the approach for an innovative Decision Aid Support System (DASS) that will provide evasive recommendations for the Commanding Officer (CO), Officer of the Deck (OOD), and tracking party during the critical time that occurs immediately following the detection of a possible hostile torpedo. DASS will allow the CO, OOD, and tracking party to review and modify tactics during the mission planning phase and then draw on those tactics in the high-stress environment, which occurs subsequent to the detection of a suspected hostile torpedo. DASS will not only provide evasive recommendations in a timely manner, but will also provide comprehensive insight into the decision-making process. This insight allows the user to view and modify DASS recommendations, observe the relationship between the recommendations and the raw data, and execute the plan. DASS will enable the user to override any portion of this plan and will modify the plan accordingly. DASS will consist of displays, controls, and algorithms, that provide a seamless integration of tactics and sensor data into the decision-making process and allow the operator to be involved in that process. This distinctive feature will facilitate the acceptance of this new concept by the Submarine Navy. The displays will utilize formats that provide quick visualization and assimilation of the information and controls that allow easy modification of that information, using familiar concepts. The user interface will be supported by knowledge-based algorithms that will recommend own ship evasive maneuvers, countermeasures (CMs) and torpedo launches. Unique to DASS will be its ability to develop recommended decisions with incomplete and inconsistent data. A proposed DASS option would utilize new technologies, including but not be limited to, eye monitoring, brain monitoring, motion monitoring, advanced touch screens, automated verbal commands, and haptics (body pressure devices). Body monitoring technologies would allow DASS to quickly react to subtle commands. Brain monitoring will allow DASS to detect user confusion and provide added support. Eye monitoring will allow DASS to detect when the user is searching for information and automatically provide that information. Touch screens will allow easier entry of commands. A commercial DASS version would be an ideal decision aid in numerous crisis management situations, such as operating rooms, commercial airplane cockpits, airport control towers, nuclear power plants, robotic assembly facilities, and municipal traffic control. Each of these situations should have a plan prior to a crisis, sensor information to monitor the crisis, and will sometimes have to make a decision with incomplete or inconsistent information. DASS development will be supported by a simulation system, which will be used to demonstrate and evaluate the concepts.

Title:Shared Situation Awareness (SSA) Measurement
Abstract:DDL Omni Engineering and the Klein Associates Division (KAD) of Applied Research Associates (ARA) have teamed to conduct research related to measuring the state of Shared Situational Awareness (SSA) during distributed near-real time military operations. Our scope will focus on the Anti Submarine Warfare (ASW) domain of naval operations. The Phase I research will apply a naturalistic ‘Sensemaking Data Frame’ model concept, developed by KAD, based on critical ASW planning and operational assumptions. Detailed knowledge of typical assumptions will be used as anchors in the Data Frame. The ASW Data Frame model will provide the basis for a software tool that will allow participants in a distributed operational environmental to continuously assess/monitor the validity of mission critical assumptions based on their individual (local) situational awareness (SA) and easily communicate to other participants in a network when they have reason to question the validity of a mission time-critical assumption. At a tactical level, the degree or quality of SSA is reflected in acceptance of the most important assumptions underlying actual decisions. While agreement indicates a high degree of SSA, questions or disagreement with critical assumptions is a qualitative measure of divergence or loss of SSA.

Title:Shared Situation Awareness (SSA) Measurement
Abstract:SA Technologies proposes to advance the Navy’s capacity to accurately, efficiently, and reliably assess naval tacticians performance, decision-making and Shared Situation Awareness (SSA) in an evaluation environment by bringing forth a comprehensive framework that addresses (a) the main factors affecting team performance in dynamic environments with high data uncertainty, (b) the objective and subjective performance assessment dimensions related to team performance factors, and (c) the individual and team performance metrics obtained from the assessed performance dimensions. To that aim, SA Technologies proposes to identify the technical requirements for a Navy assessment tool by conducting a domain analysis that will identify the most effective assessment tools to meet the Navy’s needs. Validation of existing SA requirement analyses will support the development of relevant measures. Finally, SA Technologies will draw upon its current evaluation tools and database structures to develop a plan to incorporate isolated methodologies into a comprehensive individual and team assessment tool.

Title:Advance Hybrid Air Scrubber
Abstract:To address the Navy need for rapid removal of multiple classes of pollutants from submersibles via one compact air scrubber, Physical Optics Corporation (POC) proposes to develop a new Advanced Hybrid Air Scrubber (AHAS) based on sequential application of multiple sorption/scrubbing processes. The innovation in integrating multiple scrubbing processes into a single system allows efficient removal of multiple classes of pollutants with final by-products of only oxygen and water. This reduces the use of consumables and allows continuous operation of >10 hours using a 28 V DC source. The low pressure drop across the AHAS, which is approximately the size of desktop computer, supports energy efficiency in moving air through the system, reducing total pollutant concentration by 50% in 5 min, and operational capability in 1 to 6 atm at 29 to 140 degrees F. In Phase I, POC will combine the various pollutant removal technologies to develop a laboratory- scale prototype of TRL >3. Phase I test results will lead to the design of a full-scale AHAS capable of removing pollutants from up to 1,700 cu ft of enclosed volume, and development, in Phase II, of a full-scale prototype of TRL >6 that will meet all Navy requirements.

Title:Universal Atmospheric Scrubber for SDS
Abstract:High levels of carbon dioxide (CO2) and volatile organic compounds (VOCs) can rapidly accumulate in the confined spaces of Advanced Seal Delivery Systems (ASDS) and Deep Submergence Systems (DSS). Although both single-use chemical based canisters and recycling systems are available to remove CO2 from the atmosphere on much longer missions, there is no compact high rate recycling system that can remove VOCs and CO2. TDA Research, Inc. (TDA) proposes to develop a compact trace contaminant control system that can effectively remove carbon dioxide, carbon monoxide, ammonia, hydrogen, sulfur dioxide, hydrogen sulfide, benzene, chlorine, mercury vapor, trichloroethane and other gases (as listed in Appendix F of NAVSEAINST SS800-AG- MAN-010/P-9290). In addition, the system will be capable of reducing contaminants released from the non-metallics and materials used in the manufacturing, maintenance and cleaning of the DSS (i.e. curing paints, adhesives, resins and solvents). In Phase I, we will develop a compact contaminant control system and CO2 scrubber by combining three well-identified technologies into a practical device to reduce the concentration of all contaminants below threshold levels. In Phase I, we will carry out bench-scale evaluations of the individual sorbent and catalytic filters under representative conditions. The best materials and optimum operating parameters will be selected, and a sub-scale breadboard demonstration will be carried out using TPOC approved test methods and evaluation criteria. `

Title:Universal Atmospheric Contaminant Scrubber for Submersibles
Abstract:The U.S. Navy is currently seeking innovative solutions to quickly reduce the concentration of CO2 and other contaminant gases in manned compartments aboard Deep Submergence Systems (DSS) including the Advanced SEAL Delivery System (ASDS). Confined spaces of DSS are particularly susceptible to the buildup of not only high levels of CO2, but also a wide range of other contaminant gases including CO and a variety of Volatile Organic Compounds (VOC’s). Technical Products Inc. (TPI) proposes to develop a compact, integrated contaminant removal system that not only reduces the level of CO2 and CO but also reduces that level of other contaminant gases and VOC’s below their threshold levels. This stand alone system will be designed to rapidly remove contaminants from the confined air volume, eliminating the possibility of reintroducing by-products back into the atmosphere, while at the same time minimizing maintenance requirements including the need to replace consumable components. The TPI modular design will provide the flexibility to size the system based on confined space dimensions, number of personnel and mission duration resulting in a lightweight and compact system requiring minimal power and which can be safely operated in enclosed atmospheres.

Title:Secure Open Architecture Open System Technologies for Tactical Networks
Abstract:The Naval tactical submarine environment consists of a complex set of computing requirements unique in many aspects to the environment. However, along with the uniqueness of some requirements comes other more common requirements found across many of the large Department of Defense (DoD) programs. One of the common aspects is the need to handle data at multiple levels of classification. While the tactical submarine environment has effectively implemented a periods-processing model for this task, there are other processing models that can more efficiently handle multiple levels of data due to the transition tasking for periods processing is a resource and time intensive operation. What is needed is the functionality, stability, and performance of a real-time system combined with the ease of management and capacity of an enterprise data center. The solution must adhere to Open System standards in accordance with the direction of the Navy’s future technology development and acquisition initiatives. Open Systems allow a federated group of developers each developing different applications, to all work together. Overall, Open Systems reduce cost by increasing competition, and also leverage standards based capabilities to ensure interoperability and supportability.

Title:Secure Open Architecture Open System Technologies for Tactical Networks
Abstract:Currently Submarines process data at three distinct classification levels, S, TS, SCI. The network is currently based on a floating “periods processing” model that assumes the entire network is classified at the same level and can only float upwards based on the current mission (i.e. S->TS or SCI). Once the classification level has been increased, there is no way to declassify existing material (that really should be Secret) unless it was either stored on Read Only media prior to the transition or unless it goes through a complicated data guarding process. This model is fundamentally flawed and was designed based on legacy hardware and available resources. The goal of this SBIR is to develop technologies that will segregate data of various security classification levels using approved hardware and software techniques and simplify the data access and usage for the sailors. This effort is designed to increase the productivity of the user by removing or automating the barriers currently involved with accessing data at different classification levels simultaneously. This proposal will describe a series of solutions based on Trusted Operating Systems, Centralized Data Storage, and Cloud Computing architectures that will result in a novel data & usage model with greater transparency to the users.

Title:Secure Open Architecture Open System Technologies for Tactical Networks
Abstract:Submarine tactical information systems consist of data networks of differing classifications which cannot be arbitrarily connected. Currently submarines manage these systems using period processing methods which require operators to clear the data from one network connection prior to connecting to other networks. Advances in data systems security in non-submarine environments have exhibited capabilities that could be implemented in submarine tactical networks. Current state of the art in data systems security has yet to be applied to submarine tactical networks which, due to the nature of the operating environment, must meet specific processor performance requirements, be reliable and stable, and must comply with Navy Open Architecture (NOA) standards. SOLUTE Consulting will leverage the work already in-progress on an Airborne MLS architecture and partner with the DoD leader in Multi-Level Security (MLS) technology, General Dynamics C4 Systems (GDC4S). By addressing five technical objectives, at the completion of a Phase I award SOLUTE will develop a minimum of three hardware and software architectures recommendations for use in a Phase II SBIR option. The five technical objectives are submarine MLS requirements, potential applications, security requirements, NOA requirements, and MLS architecture options.

Title:Improved Safety in Large Format Lithium-Ion Cells and Batteries
Abstract:In recent years a new separator, developed under SOCOM funding, proved to prevent failure during overcharge by limiting the cell voltage and shunting the current. Tests have been done on 4.7Ah cells charged at C/2 and have been demonstrated to successfully continue to cycle after 300% overcharge. This separator also provides thermal shutdown at 90 - 110„aC and is structurally stable to 180„aC. It is proposed to combine this latest development of a new separator with other design-in technologies to produce intrinsically safe, large format cells. These cells will be designed to provide thermal management and will contain the safest of high energy cathode materials in order to still provide 175 - 200 Wh/kg at the cell level. These large cells will be tested and revised as necessary to provide and demonstrate intrinsic safety. A battery will then be designed using these cells and incorporating thermal management systems thus providing a large battery for submersibles with significantly improved safety against catastrophic events.

YTP will also evaluate the practicality of hybrid separator systems in which the separator and/or electrodes are coated with a thin electrically insulating, temperature impervious layer. These layers would leave a residual electrical insulator in place in the result of separator failure from an over temperature condition. This creates a strong barrier to propagation resulting from an internal electrical short. Finally, YTP will model various novel cell geometries that are designed to interrupt the propagation front of a failure event. In summary, Phase I will identify the safest cathodes and anode systems that can meet the energy requirements, evaluate a novel separator system and model or empirically test the ability of novel cell geometries to terminate event propagation.

Title:Material Identification using Reflectivity Kernels
Abstract:We will apply novel material identification algorithms, developed for the US Air Force and NRO for radar, to underwater sonar. This will yield a new capability of exploiting the material and structural composition of acoustic scatterers by providing an estimate of the full scattering kernel, enabling target differentiation and offering far more information than that contained in just the specular/diffractive response: namely scattering from internal regions and internal boundaries, and reradiation or "ringing" due to the elastic response. We will adapt the radar based algorithm to a multiple aspect angle capability for sonar, concentrating on applications to torpedo sonars to reduce false homing and other performance degrading issues. Testing will be conducted in the NUWC Transducer Calibration Facility to determine the reflectivity kernel/specular response characteristics of various objects of differing materials, using available torpedo sonar characteristic waveforms and pulse durations. A library of reflectivity kernels will be created and requirements for an APB TI will be defined. Project activities will be structured to meet NAVSEA decision gate requirements for an APB, including testing with actual sonar data and developing documentation to satisfy an APB datacall.

Title:Evolving Waveforms for Acoustic Material Identification
Abstract:SciFish proposes to utilize Resonance Scattering Theory (RST) modeling to evolve a set of acoustic waveforms that provide optimal material identification while suppressing the affects of clutter and noise. Each waveform will be defined by its bandwidth, pulse width and signal type. Signal types will include FM, Hyperbolic FM, and Phase Shift Key Coded waveforms. An initial set of waveforms will be created from a random selection within each parameter space for each element of the waveform definition. After each of the waveforms has interrogated the target, a figure of merit will be used to rank each solution from best to worst. The best half of the population will be retained; the worst half will be replaced by randomly modifying each of the best half of the population. This process will be repeated until a waveform is evolved that meets our exit criteria. A figure of merit will be derived that emphasizes material identification with simultaneous rejection of clutter.

Title:Low loss self-biased ferrite materials for size and weight sensitive circulator applications requiring high power handling and high temperature stabil
Abstract:Self-biased ferrite circulator devices have been demonstrated and thus far exhibit high loss and poor isolation, making them unsuitable for practical applications. The main reason for less than satisfactory performance and high frequency of operation lie in the unacceptable quality of hexagonal ferrite materials. Metamagnetics’ researchers have developed novel materials fabrication and orientation techniques that lead to exceptionally low magnetic losses. Further, these orientation techniques have been successfully applied to substituted hexagonal ferrite materials that possess low uniaxial anisotropy, allowing self-biased devices over 2 to 20 GHz. Building upon these advances, in this proposal, the development of self-biased ferrite materials and device concepts for the 2 to 20 GHz frequencies is pursued. This program’s technical objectives can be summarized as: (i) develop low loss self-biased ferrite materials for size and weight sensitive circulator and isolator applications requiring high power handling and high temperature stability, (ii) numerically develop and optimize performance of self-biased circulator and isolator designs using material properties of advanced ferrite materials, and (iii) conduct initial experimental studies to confirm the numerical models, including self- biased or very low bias field circulation at design frequency and at elevated temperatures.

Abstract:We propose to develop a compact solid-state RF power limiter using III-Nitride technology fully compatible with that of other III-Nitride RF components (power amplifiers, RF switches etc.) The proposed limiter is based on the SET Inc. proprietary insulated gate device (MOSHFET) design and technology. Using recent achievements in the epilayer growth, contact formation and active region design, the proposed limiter will achieve a very low insertion loss (0.1- 1dB, depending on the required protection power), low noise, high maximum operating temperatures, between 300oC and 600oC or even higher, and high protection and maximum (breakdown limited) powers, well exceeding +60 dBm. The proposed technology is also capable to providing limiters with low protection powers, in the range of 15 to 30 dBm.

Title:Band Limited Pulse Encoding and Signal Classification
Abstract:Torpedo sonar systems will soon be capable of operating over much wider bandwidths than previously possible, enabled by technology insertions with improved transducers, T/R electronics, and signal processors. The proposed research investigates the use of a class of wideband acoustic waveforms to reduce the vulnerability to echo-repeater decoys while maintaining full sensitivity against actual targets of interest. Waveforms are proposed which provide unambiguous range response over time delays of at least 10 seconds, countering decoys which replay prior pulses to simulate range pull-in effects. The proposed waveforms also feature dynamically-scheduled frequency hopping, designed to minimize predictability and detectability. An assessment of computational complexity for the associated detection processing is included in the proposed research effort, covering both fully-coherent wideband processing and a semi-coherent pulse processing method for reduced compute load.

Title:Intrinsically Damping Composites
Abstract:Nanostructured epoxies are proposed as matrices for intrinsically damping glass fiber reinforced composites. Comprising blends of standard epoxy resins modified by addition of liquid thermoplastic polymers and complex anion electrolytes, these materials self- structure during cure to form co-continuous networks of high strength epoxy and linear polymer having nano-scale inter-domain dimensions. The unique morphology and high interfacial area provide these materials with rigidity, toughness and an inherent vibrational damping capability of 5%. These blends strongly bond to glass fiber reinforcements and have a proven ability to form high strength composite materials. In this research this technology will be exploited to provide self-damping composites specifically engineered for submarine application.

Abstract:Marine composite structures can be subjected to continuous excitation forces when underway. Acoustic treatments such as damping tiles have been shown to be effective but can add significant parasitic weight and manufacturing and maintenance complexity to the vehicle. In this proposal, Materials Sciences Corporation presents a plan to develop and demonstrate passive damping concepts that reduce structural vibration levels and noise signatures in marine composite structures through use of innovative materials and fiber architectures. This objective will be met by validating of material models that facilitate materials design studies, demonstrating, via experiments, innovative material solutions that minimize parasitic mass, are structurally robust and yet deliver maximum vibration attenuation. Manufacturing demonstrations are planned to show that the material solutions proposed are feasible for marine composite structures.

Title:Implosion-Proof SOF Mission Equipment Storage Container
Abstract:The ultimate goal of the Phase I effort is to research the most common failure modes of small implodable volumes in order to determine characteristics of the resultant shock wave and determine what hazards this shock wave represents to divers. Texas Research Institute Austin, Inc. (TRI/Austin) will develop a man portable container that protects divers from multiple hazards related to equipment being carried, including harmful off-gassing and flammability of contents under pressure, and implosion or explosion of small sealed volumes due to pressure changes. TRI/Austin is in a unique position to transfer technology and lesson learned from previous implosion and blast mitigation projects to ensure success at the lowest cost. TRI/Austin will use our knowledge and equipment from this past research to modify the existing Special Operation (SOF) diver bag to mitigate the hazards associated with implosion, explosion, and fire. The existing bag will provide the requirement of waterproof and containment of the VOC. To prove the feasibility of this goal TRI/Austin will design and fabricate a 200 cubic inch implodable volume and test the diver’s bag by imploding the volume within the bag.

Title:Energy Dynamically-Tuned Absorbing Sheet for Underwater Implosion Mitigation(1001-436)
Abstract:Triton Systems Inc., with Draper Laboratory, proposes to develop a SOF mission equipment container containing damping mechanisms to neutralize the adverse effects of stored equipment implosion. This container will be a flexible bag that can be rolled up while not in use, provides a rugged waterproof envelope, contains harmful outgassing, and incorporates fire retardant elements. The basic concept is to enclose the implodable equipments with a layer of material having large hysteresis in its stress-strain behaviour. Candidate materials include rate sensitive reticulated elastomers, plastic honeycomb-like, and cellular polymeric materials. Static stiffness will be tailored to accommodate the operational depths/pressures, and the dynamic stiffness will be defined to absorb the requisite implosion energy at a TBD thickness. A simplified dynamic model of the implodable volume/container/swimmer system will be formulated to provide parametric assessment of the bag performance. Likely diver injury mechanisms due to an implosion will be evaluated to identify the thresholds of dynamic response. Candidate material stackups will be fabricated in Phase I and subjected to instrumented drop weight testing to validate their performance. During the Phase II a pre-prototype equipment container with implosion mitigation will be fabricated and subjected to operational loadings to evaluate compliance with the solicitation requirements.

Title:Synthetic Elements for Moving Line Arrays
Abstract:Uniformly spaced line arrays (ULAs) exhibit spatial ambiguities governed by to the Nyquist sampling theorem. This results in grating-lobes which degrade array gain and also results in direction of arrival estimation ambiguities for signals of interest. The challenge associated with the formation of synthetic elements for line arrays (SELA) to eliminate grating lobes and perform failed channel recovery for ULAs is discussed. Objectives of the solicitation and the Phase I Basic and Option work are given. These objectives are to develop methodologies and SELA algorithms for exploiting towed array motion to process higher frequency regions at all steered directions in order to use the full frequency capability of a ULA; and to develop methods to mitigate the effects of missing array elements to improve beamformer performance in a degraded submarine (or other) towed array. A schedule and work plan is presented that is focused around the development and evaluation of algorithms addressing these two objectives. A Phase I Option work plan is submitted in which we propose developing a framework for real-time SELA algorithm implementation, performing an analysis of alternatives that includes estimate processor timing and sizing estimates for the proposed algorithms.

Title:Synthetic Elements for Moving Line Arrays - MP 85-09
Abstract:Towed arrays provide the potential for creating synthetic elements located at positions a fraction of the distance between the actual elements, thus sampling the spatial field at a higher rate and allowing for operation at higher frequencies without grating lobes. Synthetic elements may also be used to fill in for failed sensors. The ability of a towed array system to fully exploit the synthetic elements and achieve the performance of the equivalent fully populated array depends on the temporal and spatial coherence of the observed signals. In Phase I, we will develop a mathematical framework for analyzing the towed array passive synthetic aperture sonar system that takes into account the statistical properties of realistic broadband and narrowband source signals and noise, develop a set of adaptive beamforming and DOA estimation algorithms that can be applied to a variety of broadband and narrowband signal and noise models, and analyze the performance using a suitable set of performance metrics and bounds. The algorithms will be tested on simulated data and implementated in an architecture that is suitable for processing real data.

Title:Compact Dipping Sonar for Unmanned Surface Vehicles (USVs)
Abstract:During the Phase I effort we will design a small, lightweight dipping sonar using innovative transducer and handling system technology. The key innovation in the transducer is an array of segmented flexural discs which will provide both projector and beamformed receiver functionality. By combining these two components, we save a significant amount of space and weight while ending up with greater transducer sensitivity and directionality than would otherwise be possible. Our handling system effort will take advantage of previous SBIR work for autonomous over-boarding of the legacy UDS system. This innovative design will be modified to work with a lighter transducer and reeling machine to provide a UDS system weighing hundreds of pounds less than the legacy system. Our team will also propose autonomous handling system software and advanced beamforming and auto-detection algorithms and will develop the requisite interface control documentation to build a prototype system in a Phase II effort.

Abstract:This proposed effort evaluates the specific requirements for a USV mounted dipping sonar system and develops a design for a dipping sonar system to satisfy those requirements. The Navy has investigated the installation of unmodified helicopter dipping sonars onto USV platforms but found the resulting size and weight impact to the USV to be prohibitive. The proposed design modifies the existing MH-60R AQS-22 dipping sonar system to tailor it to the specific USV application. The proposed design significantly decreases physical size and weight, provides equivalent sonar performance, and provides a low total ownership cost. In addition to developing an improved dipping sonar system design, the proposed effort also addresses the overall processing architecture required to move processed sonar sensor data from the remote USV back to the sonar operator on the LCS platform.

Abstract:The objective of this Phase I SBIR program is to develop innovative hybrid polyorganosiloxane nanocomposite protective coatings for preventing inter-granular corrosion in sensitized 5000 series aluminum alloys. The novel nanocomposite coatings would consist of NanoSonic’s marine durable fluorinated polyorganosiloxane coatings and reinforcing metal oxide nanoparticles. The proposed hybrid inorganic – organic nontoxic anticorrosion coatings will provide a durable, low cost solution for preventing stress corrosion cracking and exfoliation corrosion to aluminum alloys subjected to prolonged tensile stresses in marine environments. To facilitate near term entry within current and future naval combatants, researchers will molecularly engineer the proposed fluorinated nanocomposite coatings for strong adhesion to aluminum alloys without the use of prime coats, zero-VOC spray deposition techniques using legacy airless spray equipment and a cost target of < $8 / lb. Of particular interest, the base polyorganosiloxane templates for the proposed effort have demonstrated exceptional corrosion protection to a broad spectrum of aluminum alloys during the salt – fog corrosion test (ASTM B117), blast / ballistic protection to underlying metal alloy substrates, environmentally VOC-free deposition conditions and negligible marine biofouling within highly active marine media.

Abstract:The objectives of proposal are to create effective and durable barrier and passivating coating that will satisfy all requirements of MIL-PRF-24647D(SH) and mitigate intergranular corrosion in sensitized 5000 series aluminum alloys, as well as to identify the best application techniques for such coating. POLYMERight plans to create the targeted coating by transferring its proven innovative approach to the development of effective marine anticorrosive coatings for steel to 5XXX series aluminum. The coating will have tri- pronged action: it will be a sensitization barrier for aluminum/magnesium alloys, it will passivate the surface of such alloys, and it will serve as impermeable barrier to moisture and ionic specimens that are typically present in marine environment and cause corrosion. POLYMERight will achieve the set goals by utilizing its innovative patented polysulfide- epoxy based chemistry that was already used in the creation of multiple successful primers and coatings with superior protection properties. Polysulfide-epoxies are very attractive choice as they have one of the lowest moisture and gas permeabilities among all polymers, excellent affinity to metals, outstanding chemical and environmental resistance and attractive tensile properties. New types of oxidative functional groups can be attached to the polymeric backbones and serve as passivating agents for aluminum.

Title:Innovative Coating for Protection of 5000-Series Aluminum Alloys
Abstract:Anti-corrosion coatings are critical to protecting and maintaining the integrity of U.S. Navy ships. The steel and aluminum metal on the marine vessel must be protected from the high humidty and salt spray of the marine environment. 5000 series aluminum used on naval ships is a very corrosion resistance aluminum alloy. However, when these alloy have high levels of magnesium (>3%) they alloys are susceptible to being sensitized and undergoing stress corrosion cracking or exfoliation cracking at the grain boundary. Unfortunately, current naval ship coating systems do not provide a sufficient environmental barrier to protect sensitized aluminum 5000. TDA has recently developed a new class of corrosion inhibiting nanomaterial additives that can dramatically increase the corrosion protection performance of epoxy coatings. The inclusion of TDA’s corrosion inhibitors in an epoxy coating will provide the needed performance boast to protect these alloys in the aggressive marine environment. In the Phase I we will incorporate the TDA’s nanomaterial corrosion inhibitors into a high performance epoxy resin system for naval ships. We will demonstrate that the coating system is effective at protecting sensitized 5000 series aluminum from stress corrosion cracking.

Title:Lightweight, CTE Matched Copper Graphite Composite Cores For Enhanced PCB Thermal Management
Abstract:Thermal Management, CTE control, and mechanical stability are critical for lightweight aerospace/defense printed circuit board (PCB) applications. Current materials for PCBs do not adequately address thermal, reliability, and weight reduction in a single material solution. Historically, the solutions used today have been the same solutions used over the last few decades. The introduction of copper or aluminum into the circuit card, or more exotic materials like copper invar copper, or graphite epoxy laminates with copper foil cladding when thermal & CTE control is required have been the most popular. However, with the new generation of electronics comes the need to develop the next generation of thermal conductive materials. The new materials developed must offer higher thermal conductivity in addition to being thinner, lighter, and fit within existing printed circuit manufacturing processes. MMCC proposes to develop and demonstrate thin copper graphite composite sheets made by pressure infiltration casting will significantly advance current state of the art PCB thermal management.

Title:Grain boundary engineering of high performance ferrite cores required for high frequency power electronic components
Abstract:The development of a high performance ferrite material with capability of 1 to 7 MHz 3dB frequency is pursued. The proposed ferrite material consists of MnZn-ferrite particles with a thin coating of NiZn-ferrite. The role of the NiZn-ferrite coating is to suppress eddy currents, by providing an insulating oxide layer at the grain boundary, without significantly reducing the magnetic flux density, permeability, or allowing the possibility of the tunneling effect. Sources of power loss in ferrite cores are analyzed and practical methods for reducing their effect are presented. Materials fabrication techniques include chemical co-precipitation and spin-spray deposition, both of which lend themselves naturally to large scale production. High magnetic flux density (Bs ~ 550 mT) and permeability (µR ~ 500-20,000) of MnZn-ferrite, combined with an optimized microstructure and engineered interface, hold promise in achieving materials properties necessary for the development of power systems required to support next generation T/R modules in AESA and EW systems. The proposed technology represents a possible pathway to achieving size, weight, and cost reductions, along with increased stability and reduced life degradation in future Navy power systems.

Title:Weld Penetration Monitoring and Feedback Control in Submerged Arc Welding
Abstract:This SBIR project aims at the development of an innovative technology that can be attached to existing submerged arc welding (SAW) systems to monitor and feedback control the depth of weld penetration. Existing SAW systems will be operated using existing welding procedures without modifications. In many applications skilled welders may adjust the welding parameters based on their observation of dynamic weld pool surface to successfully control the weld penetration. Although for SAW the weld pool surface is not observable, it may/should still provide necessary information to estimate the weld penetration. A method is thus proposed to generate a dynamic change in submerged arc weld pool and then estimate this change from arc electrical signals that can be easily measured. The Phase I project aims at proving the feasibility of the proposed method through developing a laboratory monitoring/control system, using it to feedback control the weld penetration at different levels, and verifying the monitoring/control accuracy through comparison with actual welds. The Phase II project will develop a commercial prototype system, demonstrate benefits through increasing the thickness for no back-gouging two-sided butt welding, on-site demonstrate the system and benefits at selected shipyards, and prepare for the military qualification and transition.

Title:In-Line Weld Penetration Monitor Using Laser Ultrasonics
Abstract:Submerged arc welding is commonly used for joining thick plates in panel-line assembly. This technique normally involves double-sided welding, with significant preparation on the back side to promote adequate weld penetration. Currently, completed welds are inspected by ultrasonic or radiographic techniques after a delay to allow cooling. If incomplete penetration is detected, the flawed region is likely to be extensive, and considerable repair or rework is required. In this proposal we will demonstrate the feasibility of monitoring submerged arc weld penetration in real time, immediately after the weld is formed. Such an in-line technique would eliminate slow, costly post-process inspection and would allow immediate corrective action if a bad weld is detected. The technique we will apply is laser ultrasonics. The use of lasers for generating and detecting ultrasonic waves enables inspection on parts with rough surfaces that can be moving and/or at high temperature. In this project we will establish the best inspection configuration and test welds and analyze shipyard affordability.

Title:Compton Imaging Tomography System for In-Process Submerged Arc Welding Quality Control
Abstract:To address the Navy need for the methodologies and associated enabling technologies to accurately control the depth of weld penetration during the Submerged Arc Welding (SAW) process, Physical Optics Corporation (POC) proposes to develop a completely novel Compton Imaging Tomography System for in-process SAW quality control (CITSAW). The CITSAW system contains: 1) an industrial 200–450 keV X-ray source; 2) an X-ray camera based on a POC-developed apodized Gaussian aperture array, a high- absorption and high-resolution capillary scintillator, and a sensitive CCD camera with a powerful image intensifier; and 3) POC’s original software for CIT providing real-time, current welding depth finding for SAW process control, and other defect detection (if necessary) using full 3D-image reconstruction. The X-ray source and the X-ray camera are both mounted in one case, on the same side of the object, and moved together with SAW electrodes along a weld. In Phase I, POC will demonstrate feasibility of the system for measurement of the depth of weld penetration using prepared coupons and a benchtop prototype, and make estimates of the return on investment and Total Ownership Cost reduction when CITSAW is implemented. In Phase II, POC will design and test a full CITSAW system prototype.

Title:MMIC EMI Passivation Coating
Abstract:Microwave and mm-wave modules often leverage a combination of MMIC die, discrete devices, circuits on ceramics, and bond wires assembled into a metal housing that typically contains a series of connectors. While modern microelectronics has largely done away with hermetic packaging, many microwave modules still use hermetic lids to seal the enclosures, providing the dual function of protecting the circuits from environmental damage and blocking EMI to and from the circuit. This packaging approach incurs a significant cost penalty to the device, but the sensitivity of microwave circuit components to their local environment has prevented the use of more common, less expensive potting and plastic encapsulation solutions because it changes the behavior of the underlying circuit and can cause significant variation over time and temperature. During the Phase I project, Nuvotronics and its development team will investigate several novel material coating approaches to this problem, and determine the best solution based on cost, microwave performance, manufacturability, and long term reliability. The optimum solution will then move forward to a full scale Phase II development, and form the basis of a new EMI/passivation coating platform integrated into Nuvotronics passive component product line and provided to MMIC suppliers for DOD applications.

Title:Real-Time Hull Shape Monitor
Abstract:Aither’s proposed solution will examine the development of an innovative fiber optic hull shape sensing system based on a hybrid sensing scheme to allow for the extremely large number of measurement points required for the submarine structure. During Phase I, Aither will determine the required components for this system and attempt to determine a theoretical accuracy for the proposed system. Aither will also investigate the improvements that may be realized by incorporating the first methodology of monitoring the position of the forward and aft panels relative to the center panel on each side of the submarine into the hull shape monitoring system. Aither’s experience in fiber optic based shape sensing has been developed through multiple SBIR programs including towed sonar array shape estimation and aircraft wing shape measurement. Aither has developed patented, innovative technology through these programs and will leverage this experience to the fullest extent during the SBIR effort. Aither is well aware of the difficulties in not only developing a submarine hull shape monitoring system, but also with integrating the required optical fiber sensors with the submarine structure having completed ABS certification testing for a private customer on a 10 person submarine design.

Title:At-sea Reliability with Predictive Modeling
Abstract:Background – Maintenance of complex Tactical systems is generally responsive in nature, often addressing failures through a piecemeal approach. The current maintenance environment requires an inherent level of system knowledge to monitor and maintain equipment. There are also time constraints placed on system maintenance due to the increased operational tempo of today’s submarine force. Approach - Developing an end- to-end maintenance solution that incorporates a state of the art maintenance toolkit that will provide data mining analysis, automation and scheduling of maintenance events, failure recognition to the component level and prediction of Time to Failure (TTF) will significantly reduce Mean Time To Repair (MTTR) and increase Operational Availability. Providing a flexible solution through modularization and web services will also allow the incorporation of new capabilities such as Condition Based Maintenance (CBM), automation and availability planning. Conclusion – Controlling Total Ownership Costs (TOC) requires a philosophical shift in maintenance strategies. Incorporation of new Commercial off the Shelf (COTS) technologies that allows maintenance practices to align with tactical system advances is essential in controlling costs and increasing Operational Availability.

Title:Adaptive Platform-Independent Control System for ROV Launch and Recovery
Abstract:The overall goal of the proposed research effort is the development of APICS - an Adaptive Platform-Independent Control System for launch and recovery of submersible remotely operated vehicles (ROVs). APICS will operate in constant tension mode during launch and recovery and also in active heave compensation mode to maintain constant ROV depth is a seaway. Barron Associates, Inc. and its research partners will leverage the lessons-learned from the recent Active Motion Control System (AMCS) testing and the practical experience and simulation models provided by the research team. In our opinion, an adaptive control approach is required to meet the goals of platform independence with minimal operator intervention and tuning. Adaptive control approaches excel when the dynamic model structure is known, but the model parameters are highly uncertain. The APICS control problem in our formulation meets these criteria. An issue of foremost importance includes establishment of detailed APICS hardware requirements. Building on the existing requirements and design, it is crucial to review the current architecture and ensure that an ideal active feedback control system with perfect system knowledge could meet the specifications for a single ROV and platform combination. The research team will also enhance and validate existing simulation capabilities.

Title:Multi-Platform Active Heave Compensation System
Abstract:The Navy’s primary means of rescuing personnel from a disabled submarine is the Submarine Rescue Diving and Recompression System (SRDRS). The vehicle that descends to the disabled submarine to pick up the crew is a very large Remotely Operated Vehicle (ROV) with its own specialized launch and recovery gear. Since the rescue system is manned, a timely, robust, and safe launch and recovery in potentially rough seas is essential. Proposed here is a retrofit capability for the launch and recovery system that will improve heave compensation capability and allow the system to work on any vessel of opportunity without tuning adjustments. New sensors will be added to the system to utilize all available boat motion information, and a Ship Observer algorithm will be developed. The Ship Observer algorithm is a model-based approach, but has the capability to adapt itself and converge to an accurate model of the ship motion and provide higher quality inputs to the winch control system. Phase I will assess the potential for improved performance from these two techniques, evaluate the current launch and recovery system equipment, and produce a preliminary design for a retrofit active heave compensation system.

Title:Lightweight UTDS Compatible Deck Surfacing
Abstract:KaZaK proposes to replace the latex concrete currently used as the c-channel gap filler on the UTDS magazine decking of carriers with an innovative fiberglass composite construction. The proposed deck surfacing will be a very tough and durable fiberglass laminate that will be shaped to fit exactly into the gap. The laminate structure will be anchored into the channels and leveled by the use of a small amount of mortar. Weight savings of greater than 50% are projected over the current 350 tons of latex concrete currently installed per ship. As the key components will be prefabricated and will require only a very simplified installation procedure, this approach will greatly improve the cost and time required for installation of the deck surfacing. Fire retardant and wear properties will be significantly improved versus latex concrete. Due to the material selections and robust mechanical strengths, the product will be very durable and easy to repair. KaZaK will perform FEA analysis to optimize the cost and functional properties of this improved UTDS replacement system. KaZaK will build prototypes of the proposed constructions and test for mechanical, fire retardant and wear properties to demonstrate that the material meets or exceeds the standards of Mil-D-21631.

Title:Magazine Lightweight Synthetic Decking
Abstract:SCI (Space Coatings Inc.) shall leapfrog the performance of latex concrete with the development of an advanced lightweight synthetic composite system. The system will provide a featherweight yet extremely durable level working surface for shipboard ordnance handling and stowage. This decking system is tentatively codenamed EFFECT – Extremely Functional Featherweight Engineered Composite Technology. EFFECT will meet and exceed Navy demands. On the best of US Navy vessels, EFFECT will showcase the prowess of American innovation with these highlighted features: 1) Cost effective –EFFECT lifecycle cost is much lower than that of latex concrete. 2) Unsurpassed durability – repeated MIL-D-21631 tests will leave nominal/no marks on EFFECT. 3) Lifetime service – expected 50+ years. 4) Lightweight – Although EFFECT is so tough, it weighs only 2.35 lbs per square foot at 1” thick. 5) Easily installed, removed or repaired – if a serious catastrophic event occurred, EFFECT would need only a quick repair patch. 6) Sustainable/eco-friendly, Cradle-to-Cradle design – EFFECT is green. It uses both waste and recycled materials, while it can be reborn as backyard/roof decking, after the naval vessel is decommissioned and scrapped. To achieve these, EFFECT synergizes the latest verifiable technologies, which are supported by many scientific papers.

Title:Magazine Lightweight Synthetic Decking
Abstract:The United States Navy is in need of novel synthetic decking materials to level magazine decks that utilize the Universal Tie-Down System (UTDS). Current latex concrete products add over 300 tons of weight to a ship, and it is desired that this weight be reduced by 50% or more. Texas Research Institute Austin (TRI/Austin) proposes the development of a new polymeric material that can replace the latex concrete for this application and provide the lighter weight that is needed. Polymer materials that have been developed by TRI/Austin have been shown to have excellent impact resistance and excellent resistance to indentation. In addition, these new materials are extremely resistant to fluids and harsh environmental exposures. These polymers are engineered to cure within two hours and are easily repairable if damaged, though the enhanced toughness of these materials is expected to lead to lower life cycle costs. The primary goal of the Phase I is to develop a synthetic decking material to provide the necessary properties outlined in MIL-D-21631. The feasibility of using the developed novel technology polymer for ship decking will be proven through the generation of in-house experimental mechanical, thermal, and environmental tests.

Title:Manycore, Resource Management, Dynamic/Static Application Analysis
Abstract:Lakota Technical Solutions, Inc. proposes to develop Janus, a novel solution for resource and power management on multi- and many-core architectures running numerous legacy and non-legacy applications. The Janus technology will incorporate both static source code analysis and runtime application execution analysis in order to drive dynamic resource and power management decisions including the allocation of processes/threads to cores. Janus technology will mitigate the risk of performance degradation that may occur on multi- and many-core architectures by generating process-to-core allocations that minimize the likelihood of memory and resource contentions. Additionally, Janus’ dynamic power management capabilities will provide an opportunity to reduce power expenditures by taking advantage of software-controllable chip features such as frequency/voltage scaling and circuit gating.

Title:Resource Allocation By Intelligent Task Distribution Protocol
Abstract:To address the Navy’s need for resource-centric, application-characteristic-aware, power-aware, standards-compliant, manycore processor management methods, Physical Optics Corporation (POC) proposes to develop a new Resource Allocation By Intelligent Task Distribution (RABID) protocol. This proposed protocol is based on bytecode resource extraction, resource optimization routines, pull-based job distribution, and just-in-time compilation techniques. The innovation in system architecture successfully combines standardized bytecode and just-in-time compilers with bytecode-scanning to extract task resource requirements. A novel resource assignment strategy optimally selects resources for task execution, and a unique load-balancing routine distributes tasks to processing elements while simultaneously minimizing overhead. Combined, these components provide a complete manycore processor management protocol that is natively compliant with existing standards (the core components are already standards- compliant, while added components do not alter compiled codes), is transparent to the programmer and end-user, and directly supports power-level optimizations, including dynamic clock and voltage scaling, core power cycling, and other power management strategies, thus directly meeting the PEO IWS 1.0 need. In Phase I, POC will demonstrate the feasibility of RABID by developing a pre-alpha version for evaluation. In Phase II, POC will expand the optimization capabilities of RABID, optimize the core codes, and design an embedded version of the system.

Title:Power-Efficient Adaptive-and-Robust Link OFDM (PEARL-OFDM)
Abstract:Key obstacles to extending OFDM to wireless links and networks at high-frequencies and dynamic channels are inherent low performance to Doppler and power amplifiers operation with high back-off. Other significant obstacles are multipath and impulsive noise. PEARL-OFDM combines a layered architecture with technologies that mitigate such obstacles and enable full-range rates that maximizes connectivity, add unparallel robustness to Doppler over dynamic channels, has inherent robustness to narrowband fading and impulsive noise that drastically reduces “adaptation rates” and maximizes connectivity, and achieves near-optimum power conditioning of typical variable envelope signals enabling power amplifiers operation at saturation. PEARL provides a solid infrastructure for incremental addition of relevant capabilities including TRANSEC and LPD/LPI. For this, PEARL integrates two chirp OFDM technologies with different Truly Shift Orthogonal Codes (TSOC): one with randomly chirped codes and intrinsic TRANSEC characteristics dedicated to “variable rates” and another with linearly chirped codes and intrinsic robustness to Doppler. A novel Split-Phase Shift-Keying modulation overlay “makes’ resulting OFDM signals suitable for saturated power amplifiers. Applied Radar proposes to design, develop and simulated the performance of the combined PEARL technologies during Phase I, and develop a software-define-radio testbed and demonstrate PEARL’s performance over relevant military channels during Phase II.

Abstract:Under realistic mobile radio link conditions involving ground operation with multipath, or with an extended range, OFDM modulation efficiency quickly decreases. In this SBIR program, GIRD Systems will develop methods by which the communication range of links in OFDM-based mesh networks can be extended. Communication at greater ranges with a fixed transmit power means communication at lower SNRs. In order to reliably detect the transmitted information at a low SNR, a new OFDM waveform will be designed that allows advanced signal processing techniques to be incorporated into the receiver in order to allow data recovery of weak signals in noise.

Title:Network Operations (NetOps) Data Transport Optimization Engine
Abstract:The DataSoft Cost-Effective Approaches to NetOps Optimization Engine (CANOE) limits the scope of NetOps data gathered at the source and cross-network by dynamically identifying the fraction of data that is most relevant to the current network status and transmitting or forwarding only that data. This approach is based on the observation that most of the data currently being gathered and transmitted is not interesting. Many performance monitoring parameters rarely change or vary outside of a nominal range except under fault conditions. We propose to optimize the collection of NetOps data by dynamically determining the information content and prioritizing data transmission based on information content ratings. In addition, our approach develops a simpler interface for interoperation between network management elements that focuses on the specific needs of NetOps applications while building on existing standards.

Abstract:Given limited network bandwidth and the amount of network operational data that must be transmitted, Metron, Inc. will develop a system that reduces the data into its principal components before transmission. In this proposal, we present a unique expert-system optimization tool that functions both to combine together multiple data sources using a common interface and to dynamically extract and condense relevant network data by determining the orthogonal bases for high informational content. This tool combines the programmed knowledge of network experts with advanced mathematical techniques for rapid automated informational content data mining. Furthermore, the system will translate data from disparate network management tools using a simple industry-standard interface to allow interoperability between these tools. The focus of this effort will be to demonstrate an inference engine that will dynamically determine the informational content of tactical data and extract the most significant and relevant information for transmission. A separate object-oriented algorithm will use a layered approach to translate data output from various network management tools. This translation layer is key to allowing the optimization engine to perform cross-analysis of data from a variety of tools.

Title:An Ultra Low Passive Inter-Modulation (PIM) Diplexer
Abstract:Passive Intermodulation (PIM) is a phenomenon which results from non-linear voltage/current behavior. PIM is generated when two or more frequencies interact within a non-linear component or structure. Magnetic materials, oxidized contacts, or even dissimilar base metals in the signal path can cause PIM. The resulting intermodulation products are at different frequencies from the original signals and have the potential to degrade communication systems. Advanced communication satellites with multiple payloads are susceptible to PIM interference to the communication systems. Especially vulnerable to PIM effects are receivers co-located with high power transmitters. This is a common scenario of communication satellites for mobile systems, such as the Mobile Users Objective System (MUOS), which require a high power transmitter and a sensitive receiver. The critical component at the intersection between the high power transmitter and sensitive receiver sections of a communications system is the diplexer. The diplexer must effectively isolate the high power transmit signals from the receiver. PIM generated within the diplexer has the distinct potential to seriously degrade a communications channel. As an engineering and products company with a demonstrated expertise in communications, NuWaves-Ltd. proposes to apply our extensive experience base involving high performance diplexers to this communications challenge.

Title:Highly Efficient Transmitter for High Peak to Average Power Ratio (PAPR) Waveforms
Abstract:This SBIR posits that modern communication systems use complex waveforms that have high peak-to-average power ratios (PAPR). High PAPR imposes an undesirable trade-off between efficiency and linearity on a communications transmitter. Current systems sacrifice efficiency for linear operation and the problem is expected to deepen as crest factor requirements of signals continue to climb. In this proposal, Auriga shows that it is uniquely positioned to provide a new, innovative approach to solve the issue by employing two of its well-developed, state-of-the-art technologies; a cutting-edge broadband, inverse Class F power amplifier design and an envelope tracking drain modulation technique. The Auriga solution will maintain excellent signal fidelity while dramatically improving overall transmitter efficiency for high peak-to-average power waveforms. The proposed 10W, 30 MHz to 6 GHz transmitter will cover the entire baseband burden from digital I and Q to modulated RF signal. The proposal describes the Phase I tasks to prove feasibility of the solution including both simulated and empirical evidence. It goes on to describe the planned approach to turn the proposed solution into a prototype transmitter during Phase II.

Title:Memristor-Based Morphware Technology For Software Defined Radio
Abstract:To address the Navy’s need for next-generation memristor-improved software-defined radios (SDRs), Physical Optics Corporation (POC) proposes to develop a new highly reconfigurable Memristor-based Morphware (MEMO) technology. The proposed technology offers an entirely new way of implementing the SDR, using morphware, or soft-hardware. The innovations in MEMO architecture combining hybrid memristor- transistor technology enable reconfigurability to simultaneously work with different operating standards on the same hardware, with the same elements in an SDR to be configured to act as logic, signal routing, and memory. The MEMO-based memory, (up to 100 GB/cm^2), is about 1,000x higher than today’s memory, possible because of high- chip density, in which one memristor replaces about a dozen transistors, with operating speeds of up to 100x faster than today’s SDRs. In Phase I, POC will investigate and validate all of the military SDRs’ hardware components that can possibly benefit from memristive-based morphware technology to demonstrate MEMO system feasibility. We expect that at the end of Phase II, a MEMO technology system prototype will reach technology readiness level (TRL) 5 and will be ready for initial testing for Navy use. With the ubiquity of integrated circuits in electronic devices, POC’s MEMO technology will also benefit commercial industries.

Title:3D Memristor Architectures for Software Defined Radio
Abstract:PrivaTran proposes the use of newly-developed manufacturing methods that convert materials commonly found in conventional integrated circuit (IC) manufacturing into memristor devices with increased packing density and an advanced, three-dimensional (3D) architecture. The memristor devices can be formed in the interconnect layers of a conventional IC so that the area available for underlying transistors is not affected. This approach results in a 3D architecture achieved using a single substrate without the need for bonding multiple die together with flip-chip or through-silicon-via technologies. Furthermore, the memristor devices are much smaller than single transistors for any given technology node, and will scale to smaller dimensions as IC technology continues to progress towards smaller and smaller transistor sizes. The two-terminal memristor devices have numerous advantages including on/off conductance ratios greater than 104, reversible and fast switching, long retention times and immunity to current-induced degradation. In addition, their inherent simplicity makes them highly compatible with Si- based microelectronics technology, leading to a 3D architecture that can be readily transferred into semiconductor products at the most basic, integrated circuit level.

Title:Low-Cost Orbital Debris Removal Using In-Situ Propellant
Abstract:Space Debris is a rapidly increasing problem, as evidenced by the recent COSMOS- IRIDIUM crash of February, 2009. This crash is estimated to have increased the orbital debris that is greater than 1 cm by 190,000 objects (more than 30%). Removal of the largest debris elements would eliminate the fuel that feeds such sudden escalation events, allowing future schemes for removal of smaller debris to make headway. The proposed effort will study the use of the largest debris elements (full spacecraft) as a source of propellant for their own de-orbit by ablating them away with a laser. The objectives are to develop a feasible operational scenario and vehicle concept, determine the state-of-the art of the required subsystems and evaluate the performance of typical spacecraft materials as propellants. The development of the concept and determination of the state-of-the art will be conducted as a study of the open literature, whereas the evaluation of propellant materials will be carried out experimentally.

Title:High Priority, Large Orbital Debris Remover
Abstract:Busek Co. Inc. proposes to initiate the development of a high priority, large orbital debris de-orbiting system. The proposed Orbital Debris Remover (ORDER) will be built on the Evolved Secondary Payload Adapter (ESPA) ring platform shared with other similar low cost spacecraft in development at Busek including the ESPA Orbital Maneuvering System (OMS) which delivers four secondary payloads to disparate orbits. The ORDER vehicle will shuttle between the debris pick up orbit where it will grapple large, high priority space junk such as a spent upper stage and bring it down to a 250km orbit for drag induced uncontrolled re-entry. With 2000kg debris which is the typical Centaur upper stage dry mass, up to 40 round trips are possible. The total de-orbited mass over the ORDER vehicle life reaches 80,000kg assuming a 700km initial orbit. In Phase I, we will define a concept of operations (CONOPS), detail the architecture, requirements, interfaces and major subsystems. Shared subsystems with the ESPA OMS will be emphasized to reduce cost. Debris grappling tool is the only item presently not available for procurement hence its development will be initiated. A team of highly competent companies to continue the development in Phase 2 will be formed.

Title:Low Cost Orbital Debris Removal System
Abstract:In this Phase I effort, L''Garde will establish the feasibility of using a netted trap with integrated solar sail to capture and deorbit high-payoff space debris from high and medium Earth orbits. A subscale model of the trap will be built and tested. The high-payoff debris is a hundred or so spent upper stages and dead satellites, suspected of having residual fuel in them which might explode, sending out a cloud of debris that could endanger vital space assets. Such explosions occur several times every year. L''Garde will adapt its flight-ready inflatable solar sail technologies for the design. These sails are compactly packageable, opening the possibility of multi-manifests in secondary slots for rapid threat reduction. The deorbit device is simple and passive for low cost. Optionally, a separate steerable solar sail will be developed to hop from target to target, delivering the trap & deorbit devices. Once proven, the deorbit devices can be sold to commercial satellite operators, and the solar sail technology can be sold for other uses.

Title:A Low Cost Orbital Debris Removal System
Abstract:SatNet™ is a low-cost orbital debris removal system in which a “net” is launched via a suborbital launcher into the path of a spacecraft in a highly elliptical orbit or circular low Earth orbit. The hypervelocity impact between the spacecraft and net largely destroys both and reduces the velocity of the spacecraft debris sufficiently to cause reentry within approximately a quarter orbit. For example, for a satellite in a 500 km circular orbit, reducing the debris velocity by 2% is sufficient to bring perigee below the surface of the Earth such that reentry will occur very quickly. In this approach nothing is taken to orbital velocity, and precision guidance is not required because of the relatively long loiter time at apogee for the suborbital net. Phase I will determine the feasibility of the SatNet™ system via 1) defining the system objectives based on DoD deorbit/debris mitigation guidelines and customer goals, 2) designing the SatNet™ system, including candidate suborbital launchers, the deployable net, and associated subsystems, and 3) simulating the deployment and deorbit process to verify system performance. In Phase II, a prototype deorbit system will be designed in detail, including Earth-based testing of candidate net design/material combinations.

Title:Cross-layer Queue Management and Queue-status Messages for Wireless Tactical Networks
Abstract:Defense Group Inc. (DGI) proposes a unique approach to Cross Layer Modeling of JTRS MANETs. Our approach integrates admission control with congestion management schema. We propose a schema of “Intelligently” dropping packets with three possibilities for improved JTRS network throughput: 1) Using a bypass of black traffic management state to red processing, 2) Perform proxy TCP processing in the Red gateway terminal, and 3) Perform proxy cache server into secondary storage on the proxy server. DGI’s deep experience and familiarity with the NED ENS network models will quickly and cost efficiently integrate new features into the data forwarding path. DGI demonstrates in- depth experience with integrating Red and Black networks across a Type 1 Crypto: DGI’s personnel have significant experience in JTRS, networking, modeling, crypto management including Multiple Independent Levels of Security, Multiple Levels of Independent Security and Cross Layer Switching Throughput Analysis. DGI’s PIs have successfully transitioned Navy SBIR and CEROS SBIRs into commercial practice. Mr. Roger Webb, a Senior Vice President of DGI will ensure successful transition to practical use for JTRS. DGI’s Co-PI has five patents awarded in network switching and security technologies. Our Subcontractor, DataSoft Corporation has extensive experience in OPNET and QualNet tools and modeling.

Title:Cross-Layer Cache and Queue Management for Resilient Tactical Networks (CLCQMRTN)
Abstract:Cross-Layer Cache and Queue Management for Resilient Tactical Networks (CLCQMRTN) is an integrated queue management and flow control mechanism that eliminates packet drops due to burst-induced congestion or due to disconnection in tactical wireless networks. CLCQMRTN controls TCP flow rates, works even with encrypted data packets (black core), and operates even if stable end-to-end paths are not available (disruption- tolerant networking). We propose a suite of innovative mechanisms that provide queue monitoring and overflow alerting, queue status dissemination, external buffer storage and retrieval, TCP “freezing” to operate over outages and extended storage delays, disruption-tolerant routing and alternate path routing. Our mechanisms are designed to fit within the secure IP-based Global Information Grid, and will help move future tactical networks for the Navy to an almost drop-free regime, resulting in a significantly enhanced user experience.

Title:Rapid API Verification Engine (RAVE)
Abstract:To keep a large software system development effort on schedule and on budget, it is critical to ensure compliance of all software modules to an Application Programming Interface (API) specification. Currently, the Joint Tactical Radio System (JTRS) discovers API compliance shortfalls in contractor developed software modules on an ad-hoc basis and these defects are reworked only with considerable penalties in schedule slip and cost. This would not happen if every module developer could automatically and independently verify his own component’s compliance prior to delivery, and if the systems integrator could systematically verify a component’s correctness after delivery and prior to acceptance. To succeed, we must move beyond traditional and fallible compliance solutions that rely on simple textual matching. We propose to develop a Rapid API Verification Engine (RAVE) to perform lexical, syntactic, and semantic analysis on API code to infer its true meaning. Key features of our system include a correct and efficient parsing engine built on decades of solid research, a correction suggestion engine that can automatically suggest fixes to common sources of problems, and the use of a model- view-controller framework, which allows us to quickly add multiple user interfaces and meet a broad set of client needs.

Title:Automated Analysis and Verification of Application Program Interfaces (APIs)
Abstract:The DataSoft Interface Verification Application (DIVA) provides an automated robust solution for accurate and repeatable verification of developer source code compliance to a set of Standard API’s. The tool then generates customized compliance reports for the user that accurately summarize all vendor deviations from the standard API. DIVA can verify a single API file or all of the API files in a collection at the same time and generates suitable reports for each including a summary report if verifying more than one API. Our algorithms are based on customized categories of vendor deviations and mapping of API source code into independent abstract parse trees for sorting, analysis, and comparison to minimize false positives and negatives. This focuses the comparison on the real content of the APIs, eliminating trivial text based artifacts that hinder simple text comparison tools. This fully automated tool eliminates the need for manual inspection of vendor source code and improves the overall API verification process.

Title:Automated Analysis and Verification of Application Program Interfaces (APIs)
Abstract:The Joint Tactical Radio System (JTRS) program has defined a set of standard application programming interfaces (APIs) to facilitate construction of software-defined radios. The standards define how an Operating Environment and Waveforms interact with each other. The APIs are defined in the Interface Definition Language (IDL). We apply our Conforma infrastructure for artifact assessment developed under SBIR N07-137. We develop Conforma plug-ins to verify APIs represented by IDL prior to compilation. We compare the IDL as defined in the JTRS standard to the IDL that is present in a software package delivered by a vendor to the JTRS program (termed developer IDL). Currently a portion of testing is automated through BeyondCompare, however BeyondCompare does not allow the tester to define or modify the set of rules of its syntax checker. In contrast, Conforma is a collection of open source components that is driven by a verification process and set of rules. Also the reports that Conforma generates are driven by a flexible reporting engine. Deficiencies detected include differences in names of IDL files, improper use of naming conventions (e.g., upper or lower case), differences in ordering of the APIs, and missing content from the developer IDL.

Title:Automated Analysis and Verification of Application Program Interfaces (APIs)
Abstract:The Joint Tactical Radio System is planned to be the next-generation voice-and-data radio used by the U.S. military in field operations after 2010. The Joint Program Executive Office for JTRS is in charge of insuring that software delivered by third parties is in compliance with the requisite API specification. The analysis of the code by government engineers and subsequent rework by vendors are expensive and, today, largely manual processes. Trident Systems proposes to develop an “API Compliance Analysis and Reporting Tool” (ACART) that will automate the task of analyzing a set of IDL files and comparing it to a given set of formalized API’s to determine its compliance and report compliance violations. Trident’s approach to this problem will be to “pre-parse” the formal API specifications into compatible Abstract Syntax Trees. Next IDL is then parsed into similar AST structures and compared to the pre-parsed API ASTs. Both structural, and semantic algorithms will be developed that will compare the IDL to the APIs. Next the API will be checked to determine if matches exist for each element in the API. If not, then the software is not in compliance and a report of compliance violations will be generated.
