  1. In Situ Evaluation of 3-D Woven Composite Structural Performance Using Fiber Optic Sensors

    SBC: 3TEX, Inc.            Topic: N/A

    "Three-dimensional textile reinforcement architectures with straight in-plane fibers and optimized through thickness fiber content are considered as efficient solutions for the next generation of light weight, damage tolerant, high strength compositesallowing for cost-effective manufacturing solutions. The 3-D weaving process is gentle to the fibers, thus making automated fiber optic sensor insert ...

  2. High Suction Specific Speed Inducers for Cryogenic Upper Stage Engines

    SBC: Concepts NREC, LLC            Topic: N/A

    "Pump inducer suction performance is directly linked to turbopump rotational speed and weight. It has become standard practice to use boost pumps to provide higher inlet pressure to main turbopumps. This allows for higher speed, lower weight, and moreefficient turbopumps. Propellant tank pressure is also minimized. However, the boost pumps add to the weight and complexity of the propellant ma ...

  3. Time-Exposure Acoustics for Imaging Underground Structures

    SBC: GEOPHEX, LTD.            Topic: N/A

    "We propose to develop a new technique for imaging underground facilities based on the passive monitoring of acoustic emissions from both stationary and moving equipment within such facilities. It is well known that all mechanical devices, such as motors,gears, etc, emit acoustic signals. It is possible to identify an acoustic source based on its noise spectrum. In addition, by monitoring the acou ...

  4. High-Efficiency Amplifiers with Discretely Variable Output Power

    SBC: Green Mountain Radio Research Company            Topic: N/A

    "Modern phased-array transmitters employ a separate power-amplifier (PA) module for each antenna element. The transmitted signals have time-varying envelopes and peak amplitudes that vary over a large dynamic range, resulting in inefficient amplificationby the conventional linear PAs that are presently in use. A number of techniques for efficiency improvement have been developed recently, but ma ...

  5. Development of coherent nanophotonic UV sources

    SBC: HEXATECH            Topic: N/A

    "It has been shown theoretically and experimentally, that one-dimensional photonic bandgap (1DPBG) structures enhance nonlinear effects for one to three orders of magnitude. By exploiting these effects, one can achieve efficient frequency conversion (secondand third harmonic generation, and parametric) in materials with modest nonlinear optical properties and in structures with a total path length ...

  6. Ice Phobic Materials

    SBC: MICROPHASE COATINGS, INC.            Topic: N/A

    "After 4 years of basic research, MicroPhase Coatings, Inc. was awarded a Phase I SBIR contract to develop an "ice-phobic" coating for B-2 bomber engine inlets. The coating is an epoxy-silicate base with additives of silicone and melting point depressants.It is hard, durable, slick, hydrophobic, and ice-phobic. The Phase I effort was completed in October 2001 and established technical feasibility. ...

  7. Aircrew Bladder Relief Capability

    SBC: Omni Measurement Systems, Inc.            Topic: N/A

    Omni Measurement Systems, Inc. of South Burlington, Vermont has designed a comfortable, automated bladder relief system for female and male aircrew members flying long-distance missions in aircrafts without toilet facilities. The system does not use anytype of catheter, is compact and can be worn so that it is not visible to others. The pilot can chose between two hands-free and odor-free methods ...

  8. Novel High Current Switch for Spacecraft Power Bus Control


    The proposed semiconductor-insulator-semiconductor ("SIS") is herein defined as a structure consisting of two semiconductor layers separated by an insulator. PTS proposes such a SIS structure as a latching on/off switch consisting of a GaN-AlGaN emitter orcathode and a SiC anode. The GaN cathode will be designed as an efficient electron gun or cathode. The SiC anode will be designed as both an eff ...

  9. Thermionic Converters Based on Nanostructured Carbon Materials


    "The goal of this program is the development of thermionic energy converters based on nanostructured carbon materials. Nanocrystalline diamond and carbon nanotube materials exhibit unusual electron emission properties which should lead to an all newtechnology for low temperature thermionic energy conversion. Recent results have established that these materials exhibit bright emission sites with f ...

  10. Carbon Nanotube Based Electric Propulsion Thrusters For Space applications

    SBC: XINTEK, INC.            Topic: N/A

    Small efficient cathodes have many applications in miniature space propulsion. Current thermionic emission cathodes have many drawbacks. These include low efficiency, difficulty of control and pulsation, and lack of miniaturization. ANI has developedproprietary thin film nanotube technologies that enable construction of cold cathodes with high current density, high stability, and rapid pulsation ...
