Advanced Cooling Technologies, Inc. (ACT) will develop a Fast Thermal Response Fabric Test Setup for various thermal hazard scenarios involving convection (hot gas impingement by the jet engine exhaust), radiation (fire) and combination of convection and radiation (post-crash fire of aircraft, fire flash or bomb blast). The fabric test setup will (i) measure the thermal response of various clothin ...

Ascent Solar Technologies (AST) proposes to take the next step in spacecraft solar array development, building upon previous development to make the definitive thin-film photovoltaic (TFPV) device for high-efficiency (> 20%) and high-specific power (greater than 2000 W/kg) when combined with lightweight and flexible substrates. AST will develop wide-bandgap cadmium selenide (CdSe) as a high-effic ...

This proposal describes the development and fabrication of a step and stare mid-wave infrared (MWIR) imaging system. The system employs ferroelectric liquid crystal (FLC) optical shutters and a 3x3 array of lenses for imaging one of nine different look directions onto a focal plane array. Each image tile represents approximately a 6 degree by 6 degree field of view. By virtue of its architectur ...

ABSTRACT: A non-mechanical technique for steering the field of view of lidar sensors is being proposed. This coarse steering technique allows the field of view of active sensors to be moved in precise discrete steps. The ability to scan over ±20° in one dimension has been demonstrated. For Phase II, this capability will be extended to two dimensions and implemented as a compact package. Th ...

TRS is pleased to propose an in-situ NDE imaging tool for SiC mirror surface damage (SD), sub-surface damage (SSD) and trapped internal stress detection using piezo-composite based micromachined ultrasound transducer (PCMUT) phased array technology. PCMUT technology has been developed at TRS to fabricate high frequency ultrasound transducers with broad bandwidth and high sensitivity. Phased array ...

Cultural skills are increasingly important for military actions recently undertaken by the U.S., where close continuous contact with the indigenous population is necessary. All ground forces being deployed in culturally distinct and sensitive areas need to have at least some basics skills, knowledge, and awareness of cultural norms and prohibitions. Passive learning via lectures, tutorials, vide ...

The F-22A main weapons bay experiences severe acoustic loading when exposed to the freestream. The severity and attenuation of this loading is exacerbated by the flight envelope of the F-22A aircraft, as well as the requirement to carry and release “smart” weapons throughout this envelope. This extremely harsh environment can also impact components that are mounted within the bay itself, inclu ...

Next generation liquid rocket systems envision novel designs for turbopumps that can operate at high suction speeds (i.e. low inlet pressures), and can be throttled over a wide range of low, off-design flow conditions. This is an extremely demanding flow regime where performance loss and damage from cavitation instabilities can be catastrophic since they can generate large amplitude pressure fluc ...

Upgrades to a RANS Scalar fluctuation model (SFM) used to predict variations in turbulent Prandtl and Schmidt numbers in a scramjet combustor environment are proposed. Such upgrades will permit obtaining more accurate solutions leading to improved combustor designs. Experiments to be performed in Virginia Tech (and AFRL) facilities using existing models will be performed focused on SFM validation ...

Design_Net Engineering is developing a modular, configurable network-resident data storage module called the Intelligent Data Store (IDS). The IDS was developed to serve as a stock component in an Operationally Responsive Space (ORS) depot, where it can be rapidly pulled from the shelf and placed on satellites conforming to the Space Plug and Play Avionics (SPA) standards. The IDS design incorpora ...
