Title:Smart Active Networks for Mobile Wireless Environments
Abstract:Active networks break from the traditional networking paradigm by allowing for the injection of customized computations into the network. This technology enables the rapid deployment of new network services for future Navy applications. This Phase I SBIR effort proposes an innovative active network architecture that would provide mobile warfighters with two powerful capabilities: 1) truly ubiquitous networking and 2) location-aware wireless network services (LAWNS). Ubiquitous networking refers to the ability of mobile devices to access information and communicate with a worldwide network anytime and anywhere. This capability is critical to implement the network centric warfare strategy of tomorrow that relies on rapid dissemination of information across all levels of the warfighting force. Location aware wireless network services (LAWNS) exploits the widespread availability of low-cost GPS cards for mobile computers that make warfighter location information easily available. LAWNS uses GPS-based location information provided by warfighter equipment to implement innovative protocols to support capabilities such as geographically targeted multicasts of information, range- restricted information dissemination, and location-dependent access to distributed information services. Such a capability will enable future situational awareness systems where intelligence and tactical sensor data must be exploited to provide customized, location-specific information to the force.

Title:Smart Active Networks
Abstract:A key problem with the Internet is the slowness with which the underlying IP protocol can evolve. Though this protocol is very successful, there are many things for which it is not well suited, and a variety of efforts have been initiated to revise the standard to address these shortcomings. About four years ago the Defense Advanced Projects Agency (DARPA) launched an ambitious program to develop a technology, known generally as Active Networking (AN), intended to address this problem of slow deployment. An active network is one in which the routers can be customized to run communication- oriented protocols on a per-user, per-flow, or even per-packet basis. In particular, users are allowed to deploy or invoke programs within the network rather than just at endpoints. This allows a range of new protocols to be deployed quickly within the network by programming them using a more high-level interface. The goal of this proposal is to take steps to commercialize one of the most successful and widely-used active network technologies, and take a first step toward developing applications based on that technology through an experiment on the ABONE. The basic technology is that of PLAN, the Packet Language for Active Networks, designed by the SwitchWare Project at the University of Pennsylvania. The application is endpoint emulation, a service in which an active router serves as a proxy for a destination that becomes temporarily inaccessible. Such a service would allow certain kinds of communication between two endpoints even if they were never connected to one another at the same time due to erratic network connectivity or the unavailability of the endpoints themselves. The resulting service is much more general than an "answering-machine" since it does not require designation of specific proxy to hold the message.

Title:An Advanced CAD Tool for Quantum Device Simulation
Abstract:The goal of the proposed study is to develop a commercial-quality CAD tool to aid in the development of quantum based semiconductor devices. Currently, there are no commercial computer aided design (CAD) tools available that incorporate the proper physics for designing quantum devices. In Phase I of the study an existing 1D steady-state quantum simulator, NEMO, will be enhanced to include small-signal AC analysis through S-parameter extraction for use in a circuit simulator. This effort will be performed in close collaboration with JPL and Raytheon, the original developers of the quantum simulator NEMO. The modified quantum simulator will be used for demonstration/validation studies on resonant tunneling diodes (RTDs). Also, a new CAD tool architecture will be designed for implementation in the Phase II effort. In the Phase I option drift-diffusion effects will be put in NEMO's contact models, and experimental measurements of RTDs will be carried out to validate the CAD tool. In Phase II the new architecture design will be implemented. The architecture will leverage existing grid generation, numerical solver, database, and GUI library technologies at CFDRC. The final CAD tool will be 2D/3D, steady-state/transient, allow for AC analysis, capable of S-parameter extraction, and coupled with an electronic hydrodynamic model. The completed cross-platform tool will have a new graphical front end to aid in mesh generation, problem set- up, execution, and analysis/visualization.

Title:High Speed Quantum Devices and Circuits: Modeling and Design
Abstract:This proposal describes the development of computer programs for circuit simulation based on quantum effect devices. Transient quantum effects are obtained through solutions to the time dependent Wigner equation from which device parameters will be extracted. The development of small signal and large signal applications will be simulated with input and output obtained through a newly developed Windows Graphical User Interface. The long-term goal is the development of Windows and Unix based software packages enabling engineering design of advanced devices and circuits to be realized. The device emphasized in this study is the Resonant Tunneling Diode, which has developed to the point where it is being considered for high speed digital circuits operating at 100 GHz, far beyond the upper frequency limits of silicon CMOS technology (i.e. 1 GHz). The emphasis in this study is the GUI development, incorporation of transient electron and hole transport, device hysterisis, small and large signal circuit elements, output power calculations, contributions from spatially dependent effective mass, the role of dissipation, contacts, coupled devices, and demonstration of the use of the simulation in a 100GHz logic circuit.

Title:Integrated Electronics for Vertical (CPP) GMR MRAM
Abstract:This SBIR Phase I proposal will demonstrate the feasibility of integrating current-perpendicular-to-the-plane (CPP), or vertical giant magnetoresistance (VGMR), memory cells with VLSI silicon electronics. VGMR memory technology enables ultra-high density storage capability which is predicted to surpass DRAM. Unlike DRAM, however, VGMR MRAM (magnetoresistive random access memory) is nonvolatile, meaning it retains its state even without power. In order to fully exploit the benefits of this emerging technology, it will need to be implemented using high density silicon electronics. In order to demonstrate the feasibility of building the VGMR memory the following four objectives will be met: a) identify vertical memory specifications and constraints; b) identify memory array and integrated circuit process limitations; c) design vertical memory architecture; and d) design vertical memory circuitry. With the close of the Phase I effort, NVE will have completed a preliminary VLSI circuit design, predicted device performance and yield requirements, and outlined a process for fabricating integrated VGMR memory arrays. Under Phase II, VGMR arrays will be tested and debugged using multi-chip integrated prototypes followed by fabrication and demonstration of single chip VGMR arrays fully integrated with silicon-based VLSI electronics.

Title:High Thermal Conductivity Vacuum-Compatible Microwave Absorbers
Abstract:This Small Business Innovation Research (SBIR) Phase I project will establish the feasibility of vacuum compatible, electrically lossy high thermal conductivity aluminum nitride ceramics. Aluminum nitride will be doped to increase microwave absorption without adversely affecting its thermal conductivity, dielectric strength, and vacuum compatibility. Aluminum nitride disks with the selected dopant will be produced via pressureless sintering. Density, thermal conductivity, complex permittivity of the produced disks will be measured to assess their vacuum worthiness and microwave absorption. The effects of the dopant concentration on the density, thermal conductivity, and microwave absorption will be investigated.

Abstract:The objective of this proposal is to demonstrate a single chip GPS receiver with architecture and manufacturing process appropriate to both commercial and military applications. The project covers the design, manufacture and test of an integrated circuit, which requires only an input signal from a modular GPS antenna and will output geolocation information in a digital format. The chip will be manufactured in an advanced silicon on sapphire (SOS) technology called Ultra Thin Silicon (UTSi) CMOS. This advanced technology enables integration of all RF, IF and baseband functions in a single CMOS chip, a capability not possible in any other form of CMOS.

Title:Improved Efficiency of Multicolor Light Emitting Devices Based on Short-Wavelength LEDs with Down-Converting Phosphors or Polymers
Abstract:The development of high brightness LEDs based on the (AlInGa)N materials systems has led to the possibility of revolutionary new approaches to lighting and display fabrication. For the first time, this material system permits the fabrication of efficient UV solid state sources that can be coupled to phosphors for saturated visible color and white light generation. While the operation efficiency of these UV-LED sources can be high, the total lumen output is limited because typical LED operation is in the milliwatt regime. Conventional LED fabrication technologies lead to applications requiring hundreds if not thousands of LED chips to produce high lumen output. This proposal will explore the development of advanced UV-LED designs for operation at high current (power) operation for high lumen output. This will be accomplished by developing alternate growth technology on thick GaN/sapphire substrates which can be thinned to remove the sapphire, thus improving thermal management and light extraction for high efficiency, high lumen output.

Title:Improved Performance 10 Kelvin Refrigerator for Electronic Applications
Abstract:We propose an affordable, compact, reliable, lightweight, and efficient 10K refrigerator for superconducting electronics applications. Recent advances show an improved 10K refrigerator can be developed. Significant progress developing Gifford-McMahon, Stirling, and Pulse Tube refrigerators for high-temperature superconducting (HTS) electronic applications has demonstrated several characteristics needed for an improved 10K refrigerator. Improvements in regenerator materials such as textured neodymium ribbon offer enhanced regenerator performance at temperatures below 10K. We will integrate these and other recent developments into a single refrigerator concept. The thermodynamic cycle, compressor and expander technology, regenerator materials and geometry will be selected by comparing the performance of existing components to requirements for superconducting electronics applications. Critical thermodynamic and engineering choices will be modeled, and we will select a baseline approach for Phase II. To focus concept development and guide Phase II and Phase III planning, candidate applications will be selected in consultation with potential customers and the Navy. In Phase II, we will complete detailed design, build and test the baseline refrigerator, and verify that performance meets the requirements for the Phase III application(s). In Phase III, we will partner with a vendor of superconducting electronics to build a fully integrated system (e.g. voltage standard or analog-to-digital converter.

Title:Development of SiC and GaN IMPATT Diodes
Abstract:TDI proposes to develop silicon carbide and gallium nitride high power IMPATT diodes for the operation at 35 GHz. Silicon carbide IMPATT diodes will be fabricated based on epitaxial pn structures and gallium nitride devices will be fabricated based on Schottky diodes. Recently high quality SiC and GaN epitaxial structures have been demonstrated by TDI. Highly doped (>1020 cm-3) p-type SiC materials and abrupt p+/n junctions have been grown. High- quality GaN Schottky barriers were fabricated. These results open the opportunity to develop high-power high-efficiency IMPATT diodes. The goal of the Phase I is to prove the concept and demonstrate building blocks for SiC and GaN IMPATTs. SiC IMPATT diodes and GaN BARITT diodes will be modeled to determine the optimum device structure. These simulations will be based on the transport theory and characterization of SiC and GaN materials and on the results of the breakdown field measurements in these semiconductors. In the Phase II, we will focus on the fabrication of a packaged IMPATT operating at 35 GHz. Test samples will be delivered.

Title:High Data Rate CDMA Network for VSAT
Abstract:The demand for high data rate (HDR) very small aperture terminal (VSAT) networks has been increasing in the last two years. Newer network applications require a minimum of T1 data rate (1.544 Mbps). The network must also be robust for the operating conditions of VSATs- small diameter dishes with inaccurate tracking and a cluttered terrain environment. Most commercial VSAT modems support data rates in the range of 64-128 kbps but those that do support higher data rates require significantly more transponder bandwidth and larger antenna sizes. CDMA is a perfect solution for VSATs where increased complexity and transponder bandwidth is not an option. Sigtek has identified the VSAT network market as a target ideal for the further development of our existing direct sequence modems. Using our CDMA technology, we can develop a CDMA network that solves these problems. Our existing hardware supports flexible spreading codes, variable data rates, and several types of FEC. Combined with further analysis and simulation we can develop the parameters for a VSAT network that solves many of these problems. Investigation of types of FEC, spreading codes, and interference reduction will be critical in achieving a Phase II deployment.

Title:Directional Wave Measurement from Moving Platforms
Abstract:Knowledge of ocean surface wave spectra is important in a wide variety of military and civilian oceanographic applications. We propose a method of measuring the wave directional spectrum from a moving platform such as a submerged buoy, a submerged manned or unmanned vehicle (AUV or ROV), or a small surface vessel. Our method uses the depth cells of an acoustic Doppler current profiler (ADCP) to form a virtual spatial array of velocity sensors. Platform motion is measured independently using instrumentation suitable to the platform. Wavelet analysis seems particularly well suited to meeting the challenges of this task. Our proposal builds upon a previously demonstrated capability of using an ADCP to measure wave spectra from stationary platforms.

Title:Directional Underwater Acoustic Communications Transducer
Abstract:A directional underwater acoustic transducer for modem use will be developed. The transducer will provide both vertical and horizontal directionality and operate in the 8 kHz to 20 kHz spectrum with a bandwidth of 5 kHz. The proposed transducer would provide vertical directionality through its length and horizontal directionality through multi-modal excitation of the cylinders. We plan to use a combination of omni-directional, dipole and possibly quadrupole modes of vibration to attain a directional and steerable beam. The modes will be excited and steered through selective electrical summing of the signals on the silver striping on the cylinder. It has been shown that highly directive beams may be obtained from spherical transducers [J. L. Butler and S. L. Ehrlich, " Superdirective spherical radiator," J. Acoust. Soc. Am., 61, 1427-1431 (1977)]. We plan to extend this to the case of a cylindrical radiator. Analytical and finite element modeling will be performed to verify expectations before the design is implemented. We believe this approach will yield a design compatible with current acoustic modems and provide an approach that would yield production cost below $1,000.

Title:Directional 1-3 Piezocomposite Transducer for Underwater Modems
Abstract:A directional underwater transducer is proposed to improve the performance of wireless underwater acoustic modems and data networks. Conservation of power is a central requirement of battery-operated wireless modems and instrument networks. The proposed transducer employs spatial diversity to decrease unnecessary modem wake-up cycling and thereby conserves modem power, to conserve transmitter power, and to improve data throughput balancing among the network nodes. The transduction efficiency of 1-3 piezocomposite will serve to further conserve transmitter power andimprove modem endurance. Simplicity of transducer design and construction is a key feature of thedesign to realize low cost fabrication.

Title:Low Cost Electronically Steerable Acoustic Transducer Array
Abstract:Physical Optics Corporation (POC) proposes to develop an Electronically Steerable Acoustic Array Transducer (ESAAT) for acoustic underwater communication systems. The ESAAT overcomes present state-of-the-art transducer limitations on power requirement, interceptability, signal-to-noise ratio, and cost. The key innovations of the proposed system are (1) low cost RISC microcontroller-based intelligent acoustic transducer modules, (2) a low cost inertial orientation sensor, and (3) a distributed beamforming algorithm that exploits the combined computing power of the RISC microcontrollers, eliminating the need for a high performance central processor. This unique combination of sophisticated algorithms and advanced distributed computing hardware results in a low cost directional acoustic transducer with fully electronic low latency (~ 100 microsecond) beam steering capability. The system can generate complex azimuthal beam patterns optimized for the actual network topology. The Phase I research will include: a thorough design study of an ESAAT for operation in a 5 kHz band located in an 8 to 20 kHz acoustic spectrum; fabrication of a low cost transducer module; and demonstration of the superior beam steering capabilities of the system. In addition, Phase I will focus on issues such as tilt and motion sensitivity, and compatibility with the U.S. Navy telesonar testbed.

Title:Modeling of Free Spans/Bend Radii for Cables/Pipes on Irregular Bottoms
Abstract:Oceantek proposes to develop and validate a numerical tool to incorporate into existing software systems that will allow the user to compute a true and accurate representation of the cable/pipe shape as it lays on an irregular bottom terrain. It would also include the spans and points of contact on the bottom as well as the bend radii (to compute induced stresses) developed at the contact points. As the cable/pipe is laid over the ocean bottom, it bends over obstacles and free spans are created. The severity of these bends and the length of these spans are a strong function of the bottom roughness. Given the values of water depth along specific bottom tracks, the cable/pipe properties (wet weight and bending stiffness) and the cable/pipe bottom tension, the proposed software would determine the bottom contact points, the length and locations of the free spans, and the bend radii and global forces at the contact points.

Title:Safe, Energetic Metafex Linear Shaped Charges for Salvage and Obstacle Clearance Operations
Abstract:Metafex (for metal-fueled explosive replacement) combines the technologies of explosive reaction thermochemistry and pulsed electrical power. The technology will make systems formerly requiring hazardous explosives not only safer and more energetic but also less environmentally disruptive and lower in cost. Analysis shows that Metafex energy densities are more than twice as great as those of conventional explosives. Because the energy density is greater, weapon components can be made smaller and/or more effective, yet safer, if they use Metafex in place of explosives. There are many US Navy applications, including linear shaped charges (LSC's) for salvage and obstacle clearance operations. By replacing the high explosive with Metafex, LSC's will be safer. Because they will be safer, they will be less costly to manufacture, to ship, and to use. Also, disposal of obsolete ordnance will be non-hazardous. In contrast to conventional ones, the proposed LSC's require no explosives. They are environmentally benign, can be safely shipped anywhere; and need no special handling. They will be inert until activated by energetic electrical pulses. In Phase I of the proposed project, Metafex test samples will be built and tested, and the technology will be adapted for use in LSC's.

Title:Development of Advanced Electrode Materials for Rechargeable Lithium Batteries
Abstract:PolyPlus Battery Company is developing advanced secondary batteries based on lithium polysulfide chemistry. The Navy has an immediate need for secondary batteries having energy densities superior to Ag/Zn cells. Given the high energy density of Ag/Zn chemistry, the Navy seeks alternative cathodes having theoretical energy densities in excess of 1500 Wh/kg. PolyPlus Battery Company is developing a battery based on the chemistry of lithium polysulfides. The reversible cell reaction is 2 Li + S = Li2S. The lithium polysulfide cathode has a gravimetric capacity of 1165 mAh/g and a nominal cell potential of 2.0 volts, giving a theoretical energy density of 2330 Wh/kg. The extremely high energy density of the Li/S system is 33 to 55% higher than that requested by the Navy. Furthermore, fully sealed, packaged 2 Ah cells tested at PolyPlus Battery Company's facility have demonstrated exceptionally high specific energies of 150 to 400 Wh/kg at moderate to low rate (C/3 to C/25). These cells have also demonstrated high power densities of over 800 W/kg at room temperature and over 1,000 W/kg (80 Wh/kg) at moderately elevated temperatures (60 °C). The superior characteristics of this battery chemistry seem particularly well suited to the Navy's requirements.

Title:Development of Advanced Electrode Materials for Rechargeable Lithium Batteries
Abstract:Rechargeable Battery Corporation has developed innovative bismuth modified manganese dioxide (BMMD) materials with unique electro- active properties. These BMMD materials could significantly enhance the performance of rechargeable lithium batteries, and are already the basis of an advanced Secondary Zinc Alkaline Manganese Dioxide (SZAMTM) battery technology. In the alkaline system the bismuth dopant confers deep (2-electron), reversible, cyclability to the MnO2. By complexing with soluble Mn(III) species, the bismuth serves as a redox catalyst, increasing the working voltage of the cell. Steric effects of the Bi-Mn complexes appear to prevent the formation of non-rechargeable MnO2 phases so that capacity fade in practical cells is low; 500 cycles are readily achieved. There is now direct evidence that BMMD materials can produce similar effects in rechargeable lithium systems, potentially translating into capacities of more than 500 Ah/kg and cell voltages of 3- 4+ Volts, if the same level of benefit can be achieved. Solution-phase structural stabilization constitutes an entirely new approach toward the development of manganese oxides for rechargeable lithium batteries. In this Phase I SBIR development program, various structural forms of BMMD will be incorporated into the cathode of button cells with lithium anodes and evaluated for specific capacity, cyclability and fade. Micro-structural analysis will be carried out on the material before and after cycling.

Title:Carbon Nanotube - Polymer Composites for EMI Shielding
Abstract:Single wall carbon nanotube - polymer composites will be synthesized and investigated for EMI shielding applications. Bundles of nanotubes will be prepared by an arc discharge process and dispersed in several polymer hosts as a physical mixture. Composites made from as-grown and chemically purified nanotubes will be investigated as a function of the vol.% loading, as will composites formed by laminating large area sheets of nanotube paper between polymer sheets. The effects of enhanced nanotube conductivity (chemical doping) and ferromagnetic nanoparticle additives will also be addressed. Stripline cavities operating in the 0.075 - 6 GHz range will be used to measure the complex permittivity and permeability of the composites. When applicable, the results will be modeled using an effective medium theory for composites built from dielectric hosts containing high aspect ratio conducting rods.

Title:Novel Applications for Carbon Nanotubes
Abstract:The objective of this Phase I proposal is to develop carbon nanotube composites for use in demanding electronic applications on Navy aircraft and ships. Foster-Miller proposes to meet this objective by developing an innovative conductive gap treatment system for stealth aircraft. To assist with identification of materials and requirements for low observable coatings, Foster-Miller has teamed with Northrop-Grumman, a leading manufacturer of stealth aircraft for the DoD. The proposed Foster-Miller gap sealant will be comprised of a unique combination of materials which focus on improving composite performance through the use of carbon nanotube technology. To improve nanotube adhesion to the matrix resin, and therefore further improve the mechanical and electrical properties of the composite, Foster-Miller will functionalize the nanotubes to react with and chemically bond to the matrix resin. In Phase I, Foster-Miller will complete preliminary electrical and mechanical evaluation on gap sealant test specimens and further investigate other EMI and low observable coating applications for carbon nanotube technology.

Title:Erbium (III) Ion Containing Fluoropolymers as Optical Fiber/Waveguide Amplifiers
Abstract:This SBIR Phase I research will focus on the development of Erbium based Polymer Optical Fiber (POF) Amplifiers. POFs are potential candidates in short-haul (1000 m or less) telecommunication applications such as local area networks. Currently low bandwidth copper wires are used, which cannot support the bandwidth requirements of multimedia and internet technologies. Gradient Index POFs with a bandwidth of over 2.5 Gbits/sec have recently been fabricated, which will be enough to support most of the telecommunication applications. However, attenuation of polymers is very high at 1.55 micrometers, where most long distance fiber optic systems operate. Inexpensive polymeric optical amplifiers need to be developed to extend the operational range of POFs. MTI is proposing to develop inexpensive erbium (III) ion doped POF/waveguide amplifiers by either functionalizing or doping the amorphous fluoropolymers with erbium complexes. Multilayered fluoropolymer-erbium complex thin film waveguides will be fabricated using proprietary technique. The fluorescence lifetime of the erbium- polymer materials will be optimized from various proposed fluoropolymer- erbium complex compositions. Both fiber and waveguide optical amplifiers will be fabricated and tested. Optical gains of the amplifiers will be determined. Thermal stability and laser damage threshold of the amplifiers will also be studied.

Title:High Gain Erbium Polymer Optical Fiber Amplifier
Abstract:Under the proposed project, Photon-X will demonstrate the feasibility of a compact, optically pumped, high gain, erbium perfluoro polymer optical fiber amplifier having low-loss at 1550 nm for operation in short and medium distance data communications network systems. The polymer amplifier will be based on the recent discovery at Photon-X of high performance rare earth polymer materials. The new rare earth polymers are directly synthesized at high rare earth ion concentrations (>10% wt of rare earth ion) with each metal ion encapsulated and physically buffered by insulating, covalently bonded, perfluorinated ligands that then form the polymer backbone matrix. This is distinctly different from heavily studied inorganic glasses and single crystals where rare earth ion salts are doped directly into the host but only to relatively low levels (<0.1% wt).

Title:Aircraft Large Area Lamb Corrosion Mapping System
Abstract:As the naval aviation fleet continues to age, methods for accurately predicting the presence of structural flaws-- such as hidden corrosion-- that compromise airworthiness become increasingly necessary. Ultrasonic guided waves, Lamb waves, allow large sections of aircraft structures to be rapidly inspected. However, extracting quantitative information from Lamb wave data has always involved highly trained personnel with a detailed knowledge of mechanical waveguide physics. Our proposed work focuses on a variety of different tomographic reconstruction techniques to graphically represent the Lamb wave data in quantitative maps that can be easily interpreted by technicians. Because the velocity of Lamb waves depends on thickness, for example, we can convert the traveltimes of the fundamental Lamb modes into a thickness map of the inspection region. This proposal describes practical implementations of Lamb wave tomographic imaging techniques that will be person-portable and optimized for in-the-field testing of large-area aircraft structures.

Title:MEMS Sensors for Large Area Hidden Corrosion Detection
Abstract:Sensant Corp intends to investigate the use of a new, non-contact ultrasound technology for the rapid detection of corrosion in large areas. Sensant Corp believes that recent improvements in transducer technology that now enable air-coupled inspection may overcome many of the traditional shortcomings of costly, time-consuming ultrasonic inspection systems for large areas. The recent application of micro-electromechanical systems (MEMS) technology to ultrasonic devices has created an advanced ultrasonic sensor with significantly improved dynamic range (110 db) and wide range of operating frequencies in air (2-12 MHz). These new ultrasonic transducers are fabricated in the same manner as a silicon chip using a technique known as micromachining. In many cases, these devices enable the possibility of air-coupled, non-contact inspection of materials as demonstrated by Sensant using aluminum and Plexiglas sheets. For this research, Sensant will characterize the acoustic properties of the multi-layer material to be inspected and will determine the required properties of an ultrasonic inspection system. Then, the company will develop a custom MEMS transducer to investigate the feasibility of ultrasonic inspection of multi-layer materials. To ensure rapid inspection of large areas, Sensant will evaluate both a longitudinal wave and lamb-wave approach using arrays of focused MEMS transducers.

Title:ADHER: Adherent Durable Hydrophobic Epoxy Resin Formulation for Underwater Hull Touch-Up Repair
Abstract:Marine coatings are the key materials used to protect metals against corrosion and obtain the full design service life from ships. Marine anticorrosion coatings have a significant economic impact and any breach in the anticorrosion coating that may occur due to abrasion or during docking must be repaired as quickly as possible. The most difficult portion of a ship to recoat and repair with anticorrosion coatings is the underwater hull because repairs must be done under water by divers to avoid expensive dry- docking. The present repair coating formulation disintegrates during application causes the water to be cloudy, blurs the diver's vision and contaminates the marine life. Foster-Miller proposes to develop a high performance, environmentally compliant, non-toxic, no VOC (100% solids) hull touch up repair coating that can be applied underwater without hindering the performance of the application team. The proposed repair coating will adhere well to underwater substrates, cure while immersed in water and have sufficient water-resistance so that it doesn't disintegrate and obscure vision during application. Our proposed ADHER repair-coating formulation will also provide good adhesion, toughness, anti-blush and water resistance properties, and will readily accept additional coatings that can be applied during dry- docking.

Title:Underwater Epoxy Coating
Abstract:Navy vessels rely on epoxy coatings to protect the hull from the corrosive sea water environment, but scratches are frequently developed in these coatings during normal operations. Current formulations and application techniques used to repair damaged coatings under water produce unacceptable contamination of the water column. TDA Research, Inc. has identified novel hydrophobic curing agents which, when combined with new application methods, promise to eliminate water contamination during underwater application. Both Navy and commercial marine vessels will benefit from the availability of an environmentally acceptable repair coating suited to underwater application. In addition to repairing damaged coatings, the proposed formulation would also serve to protect dock block areas af

Title:Development of a Low-Cost Technology to Form Long Single Crystal Piezoelectric Fibers
Abstract:Advanced Cerametrics, Inc. (ACI) has developed a process to manufacture continuous filaments of piezoelectric ceramic materials and had designed and delivered transducer and actuator devices using these fibers to commercial, military and research institutions. Piezoceramic fiber composites are more desirable than other technologies in many transducer and actuator applications. ACI intends to adapt its piezoelectric fiber manufacturing process to form long lengths of single-crystal relaxor ferroelectric materials at reasonable cost. The proposed reseach is broken into three steps: 1) process chemical compatability studies and initial fiber spinning, 2) spinning trials for texturing and/or melt growth along the fiber axis and 3) prototype device development. Congruently melting materials (non-lead based) will be spun and continuously sintered in a melt-zone furnace that ACI developed to make high-temperature superconducting fiber. Incongruently melting materials (lead-based) will be melt-textured using procedures requiring a controlled-atmosphere, which ACI developed for monolithic HTS materials. During the research ACI will build fiber composite transducers for ultrasound and underwater acoustic applications and active fiber composites for actuator applications. By the end of Phase II ACI will have relaxor ferroelectric single-crystal fiber composite sales to its existing commercial and military customers.

Title:Single Crystal Tonpilz-Type Power Transducers
Abstract:This SBIR will address the modeling, fabrication, and testing of single crystal tonpilz-type power transducers. In collaboration with TRS Ceramics, Inc., single crystal PZN-4.5% PT piezoelectric will be integrated into the tonpilz power transducer, providing ultra high electromechanical coupling (up to 90%), high dielectric constant (up to 5500), high mechanical Q factor (up to 360), low dielectric loss (0.002) and high strain level (up to 0.5%). A direct comparison between an optimally designed single crystal PZN-4.5% PT tonpilz power transducer and an optimally designed PZT tonpilz power transducer will be made to demonstrate the performance enhancement. This phase I research will provide a basis for further transducer optimization and cost effective manufacturing of an optimally designed transducer array in Phase II. A Phase I option for modeling, construction, and testing of a sonar array element will enhance the development of the Phase II proposal.

Title:Miniature High-Strain Single Crystal Piezoelectric Actuator
Abstract:A miniature high-strain actuator is proposed that has low internal stresses and high efficiency while using single crystal piezoelectric (PZT) materials. Single crystal PZT materials provide at least 400 percent more strain than polycrystalline materials and make it possible to produce significantly smaller actuators while maintaining the same performance. Burleigh proposes to develop new design and assembly methods that that compensate for the higher strain and lower stiffness of single crystal PZT by using anisotropic composite material bonds, electrodes and interfaces. By using these anisotropic composite materials the internal stresses are minimized and the output efficiency maximized. At least these composite material concepts will be considered: (1) micro-machining (MEMS) thin arrays of support posts connected by flexible links, (2) mixing spherical particles with polymer adhesive prior to bonding, and (3) dicing thin disks from unidirectional composite rods. All these approaches have the same objective of maximizing the d33 stiffness and d31 yield strain. Practical manufacturing solutions will be investigated and identified. In the option phase, a single crystal PZT stack and flex- tensional amplifier will be designed and constructed, using the selected composite electrodes and bonds, and fully tested to characterize motion, creep, hysteresis, non-linearity, force, stiffness and resonant frequency.

Title:Actuators and Transducers from Single Crystal Piezoelectric Materials
Abstract:An innovative acoustic transducer/actuator using a single crystal piezoelectric driver will be developed. Single crystal piezoelectric materials such as PZN-4.5%PT are capable of near linear strains greater than 0.5% and a coupling coefficient as great as 92% allowing high output over a broad bandwidth. Accordingly, there is a desire to develop a transducer and/or actuator that capitalizes on these properties. Although large scale manufacturing of this material is not fully developed at this time, small sized pieces in small quantities are currently available. Because of this and because of the high cost of the small pieces, we have chosen a configuration that will allow both high displacement actuator and acoustic transducer operation with a minimum of adverse effects on the coupling coefficient. The design is based on U. S. Patent 4,845,688 and uses stiff lever arms to magnify the displacement without significant bending, which can reduce the coupling coefficient. With this design only small quantities of the single crystal should be needed to attain a high-output broad bandwidth acoustic transducer. We plan to develop a finite element model of the design and fabricate a laboratory model using single crystal material.

Title:Development of Mesoscale, Piezoelectric Single Crystal-Based Accelerometers
Abstract:The advent of single crystal piezoelectric materials is destined to have significant ramifications for the vibration instrumentation industry. Wilcoxon Research, Inc. believes, however, that one of the most promising and direct paths to commercialization is through the development of miniature, high sensitivity accelerometers. Moreover, miniature accelerometers will have overall physical dimensions in the mesoscale range, obviating the requirement of growing large diameter (> 1 cm) crystals. Wilcoxon Research, Inc. hereby proposes to demonstrate a miniature accelerometer design and prototype fabrication that makes use of piezoelectric single crystals with high electromechanical coupling. One of the major advantages of this new technology is the ability to significantly decrease the size of the sensor while maintaining the same performance when compared to conventional PZT based sensors. Due to the smaller size and unique packaging, the production cost for single crystal- based sensors has the potential of being much less than PZT sensors. Its use in embedded sensing applications, throughout the military and private sector, is expected to be widespread.

Title:High Cycle Fatigue Control Using Microelectromechanical Systems (MEMS)
Abstract:This project will study the feasibility of using MEMS fabrication technology to replace classical mechanical actuators we are currenty using for active control of High Cycle Fatigue (HCF) in gas turbine rotor blades. Left unchecked, this flexing of the rotor blades can lead to blade and engine failure By modifying the stator wakes with deployable actuators, we are able to greatly reduce rotor blade vibration. Prototype actuators have been 1/2 mm tall bumps fastened to the stator blades. These bumps must be deployable, varying their deployment with engine RPM. The existence of MEMS technology provides a potentially versatile solution, which may enable us to reduce the drag cost of wake modification. Hood Technology is currently engaged in a NAVAIR-sponsored project to demonstrate such active control of HCF in an Air Force test rig. We hope to use the MEMS actuators we propose to build under this project, in this parallel demonstration.

Title:Magnetostrictive-Piezoelectric Resonant (MPR) Stand Alone Pump
Abstract:The innovation and the resulting opportunity proposed here involves taking advantage of the increased reliability of solid state smart material actuators, coupled together with optimized electrical circuitry performance, to yield a highly efficient, compact standalone positive displacement pump. Specifically, it is proposed that piezo-electric and magnetostrictive smart material actuators based pumps be designed so that the capacitive and inductive natures of the smart materials are also properly harnessed and phased to yield a electrically resonant circuit for greater system efficiency. The benefit of this would be reduced power requirements, smaller power amplifiers, reduced heat dissipation, and in general a smaller, lighter, more affordable standalone pump system. Use of the solid state smart materials also helps increase system simplicity and reliability. While specifically focused on the dual use of magnetostrictive and piezoelectric actuators to create a more efficient total pump system, there is a great deal of freedom left to consider a wide range of specific pump types.

Title:High Authority strain and force Piezoelectric Oval Actuator Driven Pump
Abstract:The fabrication of a new generation of high authority strain and force piezoelectric actuator driven pump is proposed. The pump comprises of a pump housing, a suction valve, a delivery valve, a liquid chamber communicating to the suction and delivery ports, and a piezoelectric actuator attached to the outer surface of a vibrating plate for closing the liquid chamber. This pump offers a new generation of high frequency and high strain piezoelectric actuator which vibrates due to the application of an AC voltage. The actuator is designed using a CAD based program and fabricated directly from the Cad file using layered manufacturing process. In this process, the Fused Deposition of Ceramic (FDC) technology will be used. In this method, the actuator is fabricated by depositing PZT powder loaded thermoplastic polymer, layer by layer, along a predefined tool path which is controlled by a computer. After binder removal, sintering, electroding, and poling, the device produces large strain under the application of an electric field.

Title:Modular Rail Enclosure
Abstract:Traditional power electronics has evolved an ad-hoc packaging scheme. This, along with its challenging packaging requirements has tended to keep power electronic costs high and reliability low. The Power Electronic Building Block program has sponsored work in modular Power Electronics at various levels. One of these efforts is the Coordinated Interconnect System (CIS). The CIS is based on a cellular power bus that is simply interconnected by an array of clipped tabs at the cell perimeter. The proposed effort is to develop a modular enclosure system based on the CIS that will enable inverter designers to create custom drawers and cabinets from standard parts. The primary effort in phase one is to develop a detail design of the 'rails' for the modular enclosure, develop a low insertion force connector for the power tabs and do an overall study of the various support components for the Modular Rail Enclosure (MRE).

Title:Nondestructive Evaluation of Composite Core Structures (MSC P0B16-901)
Abstract:Multifunctional cored composites have created the opportunity to design lighter, environmentally resistant and stealthier structures for use in the topside Navy. Typical multilayer applications, such as for the AEM/S, LPD 17 and DD21 platforms have challenged both the structural designer in defining what constitutes a critical structural anomaly, and the nondestructive evaluation (NDE) engineer to find where that critical flaw has occurred. Traditional techniques have had limited success in detecting and quantifying these structural anomalies and providing a cost-effective, timely approach to inspecting very large areas of structure. This proposal will address both of these issues. The innovation and opportunity offered in this proposal is to assemble a diverse team of material developers, composite designers, and nondestructive inspection technology experts into an Integrated Product Team (IPT) for the purpose of developing a solution that will address several levels of topside NDE simultaneously. We are proposing to change the paradigm of NDE in topside structures to allow for the definition, a priori, of quantifiable damage in composite materials. This will allow for the real time disposition of a composite structure, and provide to the Naval community a methodology and suite of inspection capabilities to maintain composite materials in the fleet.

Abstract:The Phase I program proposed will demonstrate the feasibility of using shearography to rapidly and effectively inspect the Navy's multi-layered composite core structures for critical defects that effect the integrity and/or performance of these structures. These advanced composite structures are used on ship board for superstructures and hulls, as well as for primary structure on naval aircraft. These materials provide high strength to weight ratios and signature reduction as long as no critical defects are present. Speckle interferometry, using the shearography method, has been successfully used for these inspections. The TQS proposed system will incorporate advances in the technology that will provide the capabilities desired, with a direct route to commercialization.

Title:A Case Resource for Cognitive Task Analysis
Abstract:Detailed cognitive task analysis (CTA) is an invaluable tool for system design, but it is extremely resource intensive and often the results are not transferable to other design projects. There are virtually no commercial tools to support CTA, and no methods or repositories for disseminating the results. We propose to develop a convenient computer-based resource for amassing, storing, and retrieving results and methods from CTA and other task analyses using a fresh, innovative, practical approach focused on user needs. Versatility and expandability are key features of the approach. We are not committed to any one approach to task analysis, but plan to create a flexible tool. Our schema for storing and retrieving information will be driven by the needs of the users (project managers, system designers, and CTA specialists). Extensive user interviews are a key feature of Phase I. We propose to use Latent Semantic Indexing as a powerful, practical, cost-effective means for storing and retrieving information. The case resource tool will be expandable, serving a community of users who contribute to its growth. Our interdisciplinary project team combines real world experience in applying a variety of task analysis techniques with state-of-the-art expertise in database indexing and retrieval technology.

Abstract:The number and diversity of Cognitive Task Analysis (CTA) methods has grown rapidly over the past decade and continues to expand. A NATO-ONR workshop held in 1997 identified a number of issues that need to be addressed for continued growth and advancement of the CTA field.

The Phase I SBIR proposed here would begin to develop that resource. Critically important to the success of such a resource will be to identify an overarching structure and set of indexing dimensions that are meaningful and valid for a range of users. We will work with CTA specialists and prospective users of the tool to identify and develop these elements, building functionality, case content and structure, representation formats, and search and retrieval processes designed around their information needs.

Title:Intelligent Agent-Based SSCGFs
Abstract:One of the open research issues in the incorporation of battlefield stressors into CGF technology, involves the interaction of the external stressors with the personality characteristics of the individual war fighter. Further complicating this issue is the fact that the personality traits of an individual are influenced by the personality traits and the actions of other individuals (both friends and foes). Capturing this aspect within CGF technology is essential for producing realistic behaviors. In addition, these complex interactions must be represented across a range of stressor types in an efficient and user-friendly manner. "Emergent" simulations enabled by autonomous agents can be used to address this deficiency in CGF technology. Complex global behaviors of a group of agents can result from simple local interactions of these agents. Such a framework would be robust since it does not rely on rigidly scripted rules. It would also be more realistic since the interactions of agents could result in unpredictable behavior much like on the battlefield. We propose to develop one such autonomous agent model using a mathematical optimization approach which lends itself to the formulation of objective and constraint functions which can represent a wide variety of stressor models.

Title:Electric Actuator Prognostics System Development
Abstract:In this project, Foster-Miller will evaluate the likely failure modes, and the sensor and electrical signals available in the systems controllers for performing diagnostics evaluations on advanced aircraft electric actuation systems. An overall concept will be developed for a prognostics system for the electrical control and actuation systems on a More Electric Aircraft. This concept will include use of existing sensors, controller signals, and power draw signatures for prognostics. Methods for isolating the prognostics system from EMI produced by the actuators and other aircraft systems will also be investigated. Any additional sensors that may be needed for detecting specific critical failure modes will be defined. The applicability of smart sensor technology to this application will be evaluated. As part of this effort, nonlinear phase space reconstruction techniques that have been developed for vibration control and diagnostics on Navy helicopters will be investigated for their ability to define the operating regime of the aircraft and the actuator system. The ability of these techniques and other nonlinear instrument analysis techniques to provide prognostic information relative to actuator health will also be evaluated. Data on actual electromechanical actuation systems will be obtained from Sundstrand Aerospace for the feasibility evaluation.

Title:Prognostic Development Tools for Electric Actuation Systems
Abstract:New advances in electric motor technology coupled with dramatic reductions in life-cycle costs and weight have driven aircraft designers to incorporate new electric-powered actuation devices into their near-term designs. The failure of these electromechanical actuator (EMA) components is expected, but difficult to predict. Worst-case EMA failures can have tragic results, so detecting failure before it occurs is highly desirable. By analyzing both electrical modes, plus performance parameters of an operating EMA, one can determine the extent of degradation without adding additional sensors or requiring dismantling the EMA and performing a detailed inspection of its components. This "condition-based" maintenance will result in large cost savings by extending the useful life of mechanical components, extending normal maintenance cycles, and safeguarding against premature component failure. ORINCON proposes to develop a prognostic algorithm development system for automated detection and prediction of faults in an operating EMA. Our EMA Health Diagnostic (EHD) toolkit system uses advanced spectral estimation techniques, model-based condition algorithms, data fusion, and neural network processing to detect mechanical flaws and predict failures. The proposed system will enable advanced prognostic algorithm development based on operational EMA data using ORINCON's advanced spectral estimation techniques, neural net processing, and multisensor fusion.

The proposed concept builds on Athena's Fault Tolerant Control (FTC) technology, with proven demonstration in flight, real-time detection of single sensor and actuator failures. Athena's FTC achieves fault tolerance through analytic redundancy. The principles are based on deterministic non-linear control concepts and physical system dynamics, rather than genetic learning methods. The system model and failure detection filters are used to estimate the behavior of sensors and actuators, and compared to real measurements as the discriminating voting element. The proposed concept will resolve the ambiguity with multiple correlated hardware failures, while assuring stable and controllable authority throughout the flight envelope. Athena's elegant FTC implementation will enable an economical augmentation path onto current flight control systems. Subsonic air vehicles, whether strike system or commercial aircraft, are among the most vulnerable to man- portable air defense systems. The trend toward expensive survivability measures continues to strain diminishing defense budgets. Lower cost survivability options as those proposed here, are necessary to reverse this trend and assure maturation of an emerging generation of flight control systems.

Title:Use of Electric field or microwaves in control of rate and magnitude of energy release from energetic materials
Abstract:A need exists for an energetic material whose energy release rate and magnitude can be controlled so that it can provide either high internal blast or high metal acceleration or a muted output. This material is needed in conjunction with an adaptable ordnance technology program intended to develop a single package capable of producing multiple kill mechanism. Conducting Materials Corp. (CMC) has experience in increasing the burn rate of a solid composite propellant by subjecting it to an external stimuli. In this proposal, CMC proposes to control the burn rate and the magnitude of a prefabricated energetic material by using this technology and tailoring the external stimulus. This will be the objective during Phase I. In Phase II, CMC will apply this to an energetic material propellant of Navy's choice and tailor the variable output

Title:Multi-Mission Rigid Penetrator Warhead
Abstract:The objectives of this proposed Phase I SBIR effort are to develop the deign methods, manufacturing approaches, and establish preliminary performance estimates for a warhead consisting of multiple rigid penetrator segments that can be selectively deployed as a single monolythic penetrator, a column of separated penetrator sections, or a dispersed distribution of rigid penetrator segments. The effort involves analyses and design activities aimed at developing the warhead structure to achieve controlled variations in dispense patterns by sequencing and timing separation of penetrator segment packs along the length of the penetrator and by bursting each penetrator segment pack to impart a radial velocity to the individual segments. Successful development of this rigid penetrator warhead provides capability of achieving required effectiveness against a broader spectrum of targets using a single warhead, and offers the potential for selecting or altering the warhead deployment configuration to maximize its effectiveness against a specific target that may be encountered while in flight.

Title:Prediction of Structural Response to Fragmentation/Blast/Firestarting Effects
Abstract:We will develop engineering models for the structural response of kill mechanisms such as multi-fragment impacts, internal blast, and fire when acting separately or in combinations. The project scope will cover a number of conventional and advanced weapons and surface targets such as vehicles, buildings, and other equipment. Particular emphasis will be placed on the synergy between various kill mechanisms. The approach will cover a review test data and models from the literature, the development semi- empirical correlations of these data, and the development of first principles based model that improve on and complement what is in the literature. The test data will be used to guide the model development and validate the predictions. The models will enable the design of critical tests; the improvement of test data interpretation, the accurate extrapolation from tested conditions to new situations; and the effective design of new weapon concepts. The models would benefit the tri-services communities concerned with weapon development, munition lethality, and target vulnerability/survivability. The benefits will include reduce costs and schedules for R&D, testing, and new weapon systems.

Title:Intrinsic Earth Surface Material Classifier
Abstract:Currently, surface material classification is performed by manual interpretation of various enhanced images that accentuate local differences. This procedure requires analysts with in-depth knowledge of the surface and a great deal of time. The overall objective of this Phase I project is to develop an implementation plan for development of a nearly autonomous, reliable PC-based surface material classifier for visible to microwave wavelength image data. Project tasks include: (1) Develop a surface material classification scheme that is indexed to existing standard terrain attribution systems based on the abundance and importance of surface materials; (2) Establish the intrinsic properties of these materials (and typical values) that can be obtained from remote sensing data; (3) Define parameters and radiometric models that can produce surface intrinsic properties from recorded surface signals considering variable image acquisition conditions; and (4) Devise a quantitative measure of uncertainty associated with the determination of each surface element's identity. These tasks will be accomplished by leveraging our knowledge, expertise, and algorithms from 20 years of research and applications in terrain analysis and classification and from our collaborations with a number research organizations. This technology will be exported to numerous commercial applications, some of which do not yet exist.

Title:Intrinsic Earth Surface Material Classifier
Abstract:Sensor developers require the capability to easily generate scenes used to test sensor designs. As with model atmospheres used by MODTRAN/MOSART, the community recognized the need for model terrain materials with full optical/thermal specifications. This database would give users the ability to create realistic surfaces, complete with expected spectral responses at other wavelengths and environmental conditions. We propose to develop the underlying database(s) and software to use in conjunction with multiple radiative transfer models; thereby providing an enhanced surface rendering tool for simulation packages. Included will be a reclassification scheme of standard land surface types for the earth based on the abundance/importance and intrinsic physical properties. The baseline for the Master DB will be the IGBP/MODIS/NPOESS schemes. Overlying this database will be a software module that will allow the user to reclassify categories as needed or select specific categories or groups of categories. The Standard Surface Material Classifier Software will then create a dynamic, overlying Terrain Materials Database. This information is passed to surface rendering model(s) selected by the user. Surface-specific BRDF's will be calculated, if required by the selected Radiative Transfer Model(s). The user will also be able to specify viewing/illumination geometry and vary some environmental parameters.

Title:EHD Enhanced Liquid/Air Carbon-Fiber Heat Exchanger
Abstract:Advanced Thermal and Environmental Concepts (ATEC) Inc. in collaboration with Refractory Composites Inc. (RCI) propose to develop an EHD- enhanced carbon-fiber heat exchanger that can demonstrate heat transfer enhancements substantially beyond the range of conventional technology for air/liquid compact heat exchangers of significance to the AAAV program. Phase I effort will quantify the potential for substantial size/weight savings and/or performance improvement, relative to the state-of-the art technology, for EHD-enhanced air/liquid heat exchangers of interest to the AAAV program. Evaluation will capitalize on the proposers team's extensive technical know-how and experience with EHD-enhanced heat transfer and carbon-fiber composites and will employ a combination of computations and experiments to identify the best candidate(s) application for the AAAV program. Technical obstacles associated with using an EHD-enhanced carbon-fiber-composite heat exchanger for AAAV uses, such as corrosion and/or erosion and EHD-induced working fluid decomposition, electromagnetic interference, and power conditioning and/or requirement problems, will be studied. While Phase I will demonstrate the technology in laboratory-scale test modules, it will provide the design information for full scale testing of the heat exchanger in Phase II and commercialization of the technology in Phase III of the effort.

Title:Innovative Composite Heat Exchanger Technology Enhanced by Electrohydrodynamics
Abstract:Foster-Miller proposes development of an ultra-compact composite radiator design capable of operating in both land and sea environments at temperatures in excess of 250*F. Foster-Miller's design will attain equivalent efficiencies to the best metallic radiators at 1/2 to 1/5th of the volume. We will employ electrohydrodynamics (EHD) to dramatically improve the heat transfer coefficient of air. EHD, combined with our experience in composite materials, electronics industry conductor technology and aerospace industry corrosion resistant coatings, will enable critical cooling system weight reductions for the next generation of assault vehicles. The Phase I program will demonstrate several of the critical fabrication techniques needed to implement the EHD concept on the AAAV main coolant heat exchangers. Foster-Miller will work with team partners, General Dynamics Amphibious Systems (GDAS) and Land Systems (GDLS), to identify the performance requirements. Foster-Miller will utilize experimental techniques to develop the EHD parameters for ultra-compact cross flow heat exchangers. The base program will fabricate a representative cross flow heat exchanger core segment to be tested in the option. A manufacturing plan for demonstrating a cost effective EHD heat exchanger core of robust construction will be recommended at the end of the Phase I base program for implementation in Phase II.

Title:Low Cost Navigator Based on Microelectromechanical (MEM) Sensors
Abstract:The objective of this SBIR Phase I project is to design, fabricate, and evaluate a low cost, low size and weight navigator. This navigator utilizes state-of-the-art multiple microelectromechanical systems (MEMS) sensors and optimal filtering technology to achieve high precision navigation accuracy. Recently, a great deal of advancement has been obtained in manufacturing processes that allow the monolithic integration of MEMS sensors with driving, controlling, and signal processing electronics. This integration promises to improve the performance of micromechanical devices as well as reduce the cost of manufacturing and packaging. Several innovative technical approaches are proposed in this Phase I project for the design and fabrication of the multiple MEMS sensors navigator. These approaches are: modeling and high fidelity simulation of the MEMS sensors, electronic filter design, sensor configuration and sensor optimal estimation, and using zero-velocity updating to enhance navigation accuracy. This high precision, new concept design navigator will find big commercial applications in marine navigation, automotive navigation, pleasure, and military sectors.

Title:Real-Time Obstacle Detection Using a Streak Tube Imaging LIDAR (STIL)
Abstract:Grazing incidence LIDAR has been demonstrated for detection of shallow objects at significant standoff ranges. Practical application of this technique for collision avoidance requires development and integration of a compact, rugged configuration that can provide high resolution imaging over a wide swath from a maneuvering platform, with sufficient standoff range to allow the operator to avoid the detected obstacle. Arete Associates has developed a novel 3-D Imaging LIDAR system, the Streak Tube Imaging LIDAR (STIL) which can provide high resolution imaging at significant standoff ranges. The patented STIL approach is based on application of mature technologies, and has been demonstrated in the laboratory, ship-based experiments, and airborne demonstrations. STIL uses fan beam illumination, push broom imaging, and electrostatic sweep to generate high resolution images with no moving parts, yielding a rugged compact configuration for vehicle integration. Arete proposes to directly demonstrate STIL for obstacle detection at near grazing incidence by adapting and utilizing existing, proven hardware for a cost-effective Phase I concept validation. Prototype system development will follow in Phase II, and include detailed design, fabrication, integration, and demonstration of a deployable configuration for vehicle mounted obstacle detection.

Title:Marine Collision Avoidance Sonar
Abstract:A low-cost, lightweight, stealthy broadband acoustic sensor is proposed to achieve surface and subsurface obstacle avoidance (no-compromise) for Advanced Amphibious Assault Vehicles (AAAV). The Marine Collision Avoidance Sonar (MARCAS) is based on a small size, retractable sparse planar array using a minimal number of commercial off-the-shelf transducers. The MARCAS provides both high vertical and high horizontal resolution over a wide aperture to provide AAAVs' drivers with WideViewTM detection without any moving parts. WideViewTM is important because drivers must make navigation decisions not only based on forward obstacles but also on potential obstacles on either side (similar to changing lanes on a highway). Thanks to the high vertical angular resolution and because of shallow water operation, the MARCAS will discern direct-paths from multipaths (reverberation) and differentiate obstacles above and below the 20-foot "safety-depth". Finally, the MARCAS is stealthy because it uses GORCA Technologies' proprietary concept, BiopulseTM, which is coded copies of naturally occurring biological transient pulses such as shrimp sounds. The broadband frequency content of these coded pulses drastically limits shallow water propagation interference and allows detection over a range of 400m. This distance represents the "safety cushion" that gives the AAAV driver approximately 30 seconds to avoid obstacles.

Title:Expedient Foam Technologies for Marine Corps Operations
Abstract:The objective of this project is to demonstrate the capability and affordability of rigid polyurethane foams (RPF) as an expedient construction material to improve operational capability of Marine Corps units conducting expeditionary operations. The function of this material is to fill gaps or crossings, serve as a barrier or channeling material, and stabilize beaches and marshes. It will serve the function of concrete or asphalt, but it requires less material, and is easier to mix and apply. In Phase I, we propose to develop the technical specifications for the material, develop a RPF meeting those specifications, and develop a prototype machine for dispensing and mixing the ingredients to make the RPF. With this machine, we will demonstrate our ability to make the RPF meeting the specifications of the project and will prepare a quantity of product RPF for evaluation by the client agency. In Phase II, we will modify the specifications of the RPF if necessary, based on the client agency's evaluation of the product from Phase I, develop a full scale machine for field application of large amounts of the RPF that we developed in Phase I, and will carry out a field demonstration of the apparatus and material.

Title:Development and Implementation of a Lightweight/Durable Aluminum MMC Track System for the AAAV
Abstract:Advanced Refractory Technologies, Inc (ART) is currently proposing the Development and Implementation of a Lightweight/Durable Aluminum MMC Track System for the AAAV. ART, teaming with Keweenaw Research Center (KRC) at Michigan Technological University is in an excellent position to supply an track system which meets the AAAV program office needs. ART is currently in the final stages of completing a lightweight MMC track system design (52 pounds/ft) for the M2 Bradley. It will be a direct replacement for their current T157I track system, but with a weight reduction of 25% and a doubling of track life (6000 miles). Shoe strength and wear are significantly enhanced utilizing selective SiC whisker reinforcement and high pressure squeeze casting. Shoe life is enhanced through improved shoe design and rubber components. It is proposed to leverage the technology and track design developed under this program to optimize a track system for the AAAV. Both single and double-pin track systems will be addressed to meet the weight requirements. This effort will commence by reviewing the requirements of the current track design and identifying changes/improvements which are not constrained by the AAAV. It is envisioned that the shoe body, track pins, track pad, and bushing sleeves can be lightened compared to the M2 track. Based on these considerations, the ART/KRC team feels confident that a track system can de developed in phase I and fabricated in Phase II meeting a 3000 mile track life, 42-45 pounds/ft weight (30% reduction compared to steel), and 21 inch width.

Title:Development of Lightweight, Durable Composite Components for the AAAV (MSC P0A04-906)
Abstract:The Advanced Amphibious Assault Vehicle (AAAV) program office has challenged the advanced materials community to develop durable and lightweight concepts for some of the aluminum and steel components of the vehicle. In this proposal, we have assembled an integrated product team (IPT) of design engineers that are familiar with the performance requirements of the AAAV, and design considerations and manufacturing techniques unique to fiber reinforced composite materials. The objectives of the proposed work is to develop a list of AAAV components where the application of composite materials could reduce the weight by at least 30% and to provide confidence that these materials can meet the durability requirements of the vehicle. To accomplish these objectives, the IPT will conduct preliminary design and manufacturing studies for candidate components and conduct laboratory evaluations of structural elements. The IPT approach proposed here is designed to reduce risk and facilitate transition of the advanced composite designs from concept and prototyping stages into implementation on the AAAV.

Title:Armored Composite Ammunition Pressure Vessel
Abstract:We propose to develop an advanced ammunition container system that not only meets environmental and handling requirements but also provides armor protection against impacting threats and reduces the response of the stowed ammunition to an acceptable level when encountering an overmatched threat. The design of the ammunition boxes will be accomplished by an integration of advanced armor-system and composite rocket motor casing technologies. The integration of these two technologies is essential since both ballistic protection and containment of high pressure gases are simultaneously required for proper function of this component. The desired result of an overmatch threat engagement is to contain the stowed munition by preventing ejection from the container, while at the same time venting any gases to the exterior of the vehicle. There are three elements that must be addressed in the design effort; armor protection from external medium-level threats, containment of the reacting 30mm ammunition, and venting of overpressure gases. This increased protection of ammunition within the combat vehicle will improve the vehicle's ability to carry out its mission with a reduction in both the risk to the crew and the vulnerability of the system. This will also lead to satisfying IM specifications and vehicle survivability requirements.

Title:Titanium Sandwich Overpressurization Containment Ammunition Box
Abstract:This project will investigate the use of titanium sandwich panels for use on an overpressurization containment system. The manufacturing technique used will allow material to be added to the box in an efficient way and is cost effective. The joining method used is a one step process that creates no discernable change in material properties. It also has the advantage of allowing easy forming of contoured shapes. This lowers maximum pressure, allows incorporation of blast vents, accommodates a variety of interfaces, and allows a structurally efficient pressure resistant design. A series of parametric computer models will be used to analyze the maximum pressure and required vent activation pressure and cross-sectional area, after determination of the maximum credible incident for the AAAV box. A prototype cross-section test specimen will be manufactured to validate and demonstrate key features of the optimized design.

Title:High Pressure, Electrochemical Oxygen System Trickle Charger
Abstract:This Small Business Innovation Research Phase I project is directed to development of a prototype oxygen generation system design capable of delivering oxygen at 2 to 4 ambient liters per minute and generated at a pressure level of 2500 psig to trickle- charge a storage source. The technology proposed is derived from the life-support oxygen generator system developed by the team of Giner, Inc. and Treadwell Corp. (Thomaston, CT) for the U.S. Navy's Seawolf Submarine. This high-pressure electrolyzer design, based on a proton exchange membrane (PEM) to serve as an immobilized electrolyte and to separate the gases, will be modified as necessary to meet the requirements of a military aircraft application, specifically for trickle-charging a high- pressure gaseous oxygen supply. Trade-off studies will be performed on the current state-of-the-art in PEM electrolyzer technology and the conceptual design will consider material selection, size, weight, geometry, failure modes/effects, startup characteristics, safety and a performance assessment over aircraft altitude and temperature ranges. The Phase I goal will be to establish a conceptual design that meets all of the requirements for a full-scale, flight-test prototype 2500-psi Oxygen System Trickle Charger. The design process and trade-off studies will be based on in-house technology and supported by laboratory data from a working benchtop model.

Title:Electrochemical oxygen system for trickle charger
Abstract:Many types of military and commercial aircraft rely on the use of high-pressure oxygen cylinders to provide respiratory oxygen to crew members during emergency conditions. These cylinders require frequent replenishment to "top off" the oxygen gas lost during testing, inspection or use. Maintenance crews must refill cylinders on the ground. Cylinders are removed from the aircraft for refilling or are refilled in place using land based equipment. The procedures are time consuming, expensive and hazardous. There is a real danger of accidents and fire as a result of oxygen cylinder refilling. The overall goal of this program is to develop an aircraft oxygen generator for trickle-charging high-pressure gaseous oxygen supplies. The Phase I feasibility program will attempt to provide a conceptual design of the proposed system using a Polymer Electrolyte Membrane (PEM) based electrochemical stack as oxygen generator. A bench-top model capable of generating oxygen at a rate of 1 liter per minute will be built and tested to provide performance data. A study of compressor technology that can meet the requirements of size, weight and input power for this application will be conducted and a conceptual design for aircraft system would be presented.

Title:On-Board Electrolyzer Based High-Pressure Oxygen Generator System for Aircrew Breathing Oxygen
Abstract:An available source of pure oxygen, usually in the form of high pressure oxygen gas in storage cylinders, is especially important for military aircraft crews. On-board generation of high- pressure oxygen gas can decrease the ground support requirements for military (and commercial) aircraft by reducing the need for high-pressure oxygen transfer cylinders. Following preflight validation and in-flight qualification, the proposed oxygen "trickle charger" may be used to automatically replace oxygen in storage cylinders that has been consumed by aircrew personnel and/or lost through system leaks. The use of a water electrolyzer system as a "trickle charger" is ideal since the oxygen is generated from easily obtained consumables (electricity and a small amount of water). Such a system may be arbitrarily cycled on and off, oxygen generation and pressurization is accomplished with a minimal number of moving components, and the system is essentially maintenance free. The proposed system is compatible with the rigors of flight, including altitude, temperature extremes, orientation, dynamic loading, and is fully capable of performing real-time on-board diagnostics. In addition, the system is compact, lightweight, reliable, has a relatively low electrical power demand, and requires no special handling. This Phase I project will result in the development and performance testing of a breadboard electrolyzer oxygen generation system having an output of 0.5 liters per minute at a pressure of 500 psi. The system will be tested at temperature extremes including starting from a frozen state. In preparation for the development of a high pressure system (2500 psi) in Phase II, critical design aspects will be addressed as part of the Phase I effort.

Title:Cost Estimating Model for Aircraft Weapons Integration
Abstract:Developers and planners are required to prioritize the development of technologies and systems relative to user needs. Designs for new sys-tems typically only exist at the conceptual level, yet trade studies musts be performed to assess cost and effectiveness, as well as overall affordability. As new systems become more sophisticated and automated, integration costs and test/certification costs become an ever increasing proportion of the total system cost as well as schedule drivers. Devel-opers and planners require a methodology and tool-set to not only esti- mate integration and test costs and their associated schedules; but, to conduct trades between the amount of sophistication/automation and the resulting integration/test costs and schedule to derive effective, af-fordable systems. This SBIR will modify an existing methodology that currently estimates system life-cycle affordability based on performance and operational re-quirements. The estimating tool developed during this research project will be based on an existing cost tool developed for the Air Force. The tool will be capable of operating separately or as a functional element of a more detailed model. The Phase I program will demonstrate feasi- bility of the approach, develop the top-level affordability relation-ships and provide a prototype. The Phase II program will fully develop the tool and validate its accuracy.

Title:Lightning Strike Protection
Abstract:Naval and Marine Corps aircraft systems, subsystems, and components are typically designed to minimize failure due to severe lightning strikes. To minimize the effects of lightning strikes, the aircraft's exterior surface incorporates a copper mesh that is covered with an anti-static paint. This technology suffers from the high cost and difficulty of depainting and repairing damaged regions due to wear, tear, or corrosion. The depainting process is especially costly because it routinely damages the underlying copper mesh. A cost saving solution to the above problem is provided through the use of an environmentally stable, anti-corrosive polymeric/conducting metal composite appliques that can be readily applied via a peel and stick method. This proposal will demonstrate a composite applique that will consist of 1) a thin film of conducting polymer bonded to 2) an underlying low dielectric fluoropolymeric material bonded to 3) a thin film of copper metal that is 4) undercoated with an adhesive for application to metallic surfaces. This composite film is an excellent, cost savings candidate for paint replacement due to its inherent excellent thermal stability from -50 deg. C to +150 deg. C, resistance to chemical or physical corrosion, and low surface energy for reduced drag.

Abstract:Technological advancements projected for the 2025 period will potentially give the pilot a substantial increase in targeting and weapons delivery capability. In addition to technology, the 2025 force structure, warfighting strategy, platform capability and platform mission roles form the framework in which force in employed in the future. This Phase 1 effort will produce a conceptual armament system based on the 2025 capabilities for head-mounted displays, sensors, information transfer, data fusion, avionics, stores management and release, and weaponry that concentrates on optimizing the "shooter" as the key factor in mission success.

Title:Gas Turbine Hot Section Parts Innovative NDI Systems Research
Abstract:The Team of America's Phenix, Bayesian Systems and Gryphon Technologies proposes applying Bayes'Engine (TM) as an innovative non-destructive inspection (NDI) technique for increasing the number of successfully reworked gas turbine engine nozzle guide vane (NGV) segments. The proposed applications is based on the premise of consolidating available post-assembly (rework) data for the NGV segments on the Rolls Royce F402 and General Electric F404 engines that are reworked at the Naval Engine Airfoil Center (Cherry Point, NC). Bayes Theorem is the fundamental mathematical/logical principle governing the process of using logical inference or reasoning from available data to drawing a conclusion. Applying Bayes Theorem to the NGV segment rework process will account for all available relevant information (such as engine history, usage and maintenance data). Using this information and applying the Bayesian logic, the tool will develop probability curves for the possible outcomes at each available decision option. Th
