  1. Heat Transfer Prediction in Transitional Hypersonic Flow


    ABSTRACT: Our Phase II program concentrates on extending, rectifying, and validating the ETM engineering transition model for 3D flows. ETM solves PDE"s for both transition onset and intermittency and has full 3D capabilities, shown to generate swept onset curves and variable transitional lengths downstream of the onset curve. It is incorporated into Navier-Stokes codes in a manner akin to the i ...

  2. Radiation-Resistant, High-Efficiency Direct Current-Direct Current (DC-DC) Converters For Spacecraft Loads

    SBC: QorTek, Inc.            Topic: AF103080

    ABSTRACT: The new single-stage high step-down ratio/high power handling/high current capable solid-state power DC/DC converters will substantially increase the power density of radiation-resistant DC/DC converters. This new converter has the potential to boast power densities 3 5 times current state-of-the-art, while reaching radiation hardness unobtainable by conventional magnetic based solutio ...

  3. High Compliance Thermal Interface Material for Space Applications

    SBC: THERMACORE, INC.            Topic: AF103086

    ABSTRACT: Electronic boxes need to be quickly and easily attached and removed from the satellite payload deck in a spacecraft structure. Hampering the removal process is the vulcanized (RTV) used as the Thermal Interface Material, TIM. Because of its strong bond, it makes removal of the boxes time-consuming, and difficult to rework. Compounding the problem is the fact that electronics continue t ...

  4. Satellite Optical Backplane

    SBC: ACCIPITER SYSTEMS, INC            Topic: AF103097

    ABSTRACT: Data rates necessary to support the warfighter continue to increase. New satellite interconnects are needed which have minimal signal distribution weight and power overhead. Optical backplanes which accommodate these new"short haul"payload processing and"long haul"signal distribution across bus and payload subsystems are often fixed, dedicated interconnects with little to no flexibili ...

  5. Thermal Control for Operationally Responsive Space (ORS) Satellites

    SBC: THERMACORE, INC.            Topic: AF103107

    Three tiered Thermal Bus System isothermalizes the satellite, allowing payload components to be mated in arbitrary locations without requiring detailed thermal analysis. The first tier is pyrolytic graphite embedded in aluminum panels (kCore) to provide local spreading. The second tier consists of embedded heat pipes to isothermalize each panel. These heat pipes also interface with third tier whic ...

  6. Liquid Crystal Displays as Solar Protection for Space Sensors

    SBC: Dynamic Eye, Inc.            Topic: AF103113

    ABSTRACT: Space-based wide field of view cameras can be enabled to point near or directly at the sun if the sunlight is prevented from reaching any lens surfaces. A pixellated glare shield placed in front of the first lens surface that darkens in a region sufficient to shade the lens will accomplish the task. Two laminated passive matrix liquid crystal displays will achieve contrast ratios of o ...

  7. Implication of as Manufactured Delaminations on CMC the Life of Ceramic Matrix Composites

    SBC: MATERIALS RESEARCH & DESIGN INC            Topic: AF103141

    The goal of the testing is to develop and life prediction theories which describe the structural re-sponse in CMCs with delaminations emanating from manufacturing imperfections. Much work have been done studying the effects of defects in CMCs particularly in the area of porosity, but no one has clearly explained the failure mechanisms ovserved in advanced CMC jet engine after burner flaps and seal ...

  8. Defects and Damage in Ceramic Matrix Composites (CMCs) Implications for Component Life Prediction (MSC P2138)

    SBC: Materials Sciences LLC            Topic: AF103142

    A physics-based life prediction methodology for ceramic matrix composites (CMCs) which can account for the component operating environment (thermal, structural, chemical) in the context of realistic defects and damage has not been sufficiently demonstrated. The innovation offered by this proposal is a unique computationally efficient methodology for predicting both the overall effective constituti ...

  9. Nonlinear Dielectric Materials and Processing for High-Energy-Density Capacitors

    SBC: TRS CERAMICS, INC.            Topic: AF103158

    TRS Technologies, Inc. proposes to develop high energy density capacitors with stable dielectric properties for utilization in pulse power systems. The proposed ceramic capacitor will combine the best features of high energy density, low dielectric loss and high reliability. The capacitors developed on this program will have an energy density>4J/cc, low power dissipation (tanf

  10. Nonlinear Dielectric Materials and Processing for High-Energy-Density Capacitors

    SBC: Strategic Polymer Sciences, Inc.            Topic: AF103158

    We propose to develop polymer capacitor film with antiferroelectric behavior by combining a high dielectric constant polymer with antiferroelectric ceramic particles. Special processing techniques will be developed to achieve 3-D structure to enhance the dielectric performance and the dielectric breakdown strength. The novel nonlinear polymer nanodielectric materials will show a significantly high ...
