The intent of the proposed effort is to investigate the detailed composite material performance characteristics after being subjected to cryogenic temperatures and impact damage. HyPerComp Engineering, Inc. (HEI) and Utah State University (USU) further propose to correlate these characteristics to composite overwrapped pressure vessels (COPVs) and demonstrate the correlation through actual COPV t ...

Sierra Engineering Inc. and Purdue University propose to develop a non-intrusive plume instrument capable of detecting and diagnosing combustion instability. This Stability Diagnostic System (SDS) will be designed, assembled, and tested during this effort. The SDS will include a high-speed video camera and multiple photodiode detectors for observing the plume. It will also include a software pa ...

The intent of the proposed effort is to investigate the detailed composite overwrapped pressure vessel (COPV) performance characteristics after being subject to irradiation, hypervelocity micro-meteor impact, and cryogenic environments. This will result in a safer, more reliable design for high performance COPVs. This intent will be achieved via empirical characterization of composite raw materia ...

The proposed research program aims at developing a variable-fidelity software tool set for aeroservothermoelastic-propulsive (ASTE-P) modeling that can be routinely applied to the design of aerospace vehicles. The tool set can be applied to conventional vehicle types as well as hypersonic vehicles. The major issues involved in ASTE-P modeling and simulation will be significantly and extensively in ...

HyPerComp Engineering, Inc. (HEI) proposes to develop well characterized, reliable filament wound composite pressure vessels for cryogenic and other low temperature applications. The proposed effort also explores the potential for a significant improvement in filament wound composite pressure vessels performance (end results: lighter weights) through cryogenic process treatment. Both the aerospac ...

There is significant need for arrays of miniature sensors that are completely wireless. Ideally these sensors would be built as an integrated device, including sensing elements, computation/signal conditioning, communication, and an on-board power supply. However, they have not been developed due to the difficulty with integrating sensing ele-ments, and the absence of miniature power supplies. ...

Reliable energy systems with high energy density capable of operating at high temperatures, pressures and radiation levels are needed for certain NASA missions. Batteries based on solid-state ceramic oxide composite electrolytes provide the benefit of operation at temperatures up to 550o C. The current high-temperature Li battery technologies use carbonate, chloride and other molten compounds bas ...

A propulsion system is proposed that is based on acceleration of ions emitted from a thin, solid-state electrochemical ceramic membrane. This technology would provide a versatile propulsion system that would be suitable for long-term, low-thrust missions throughout the deep-space to near-Earth range. The specially formulated and fabricated membrane in combination with an applied bias voltage wil ...

Next generation General Aviation (GA) Sport Class air vehicles limited to 1200lbs, represent the first opportunity to overhaul the FAA certification process necessary to manufacture affordable aircraft. With propulsion representing over one-third of the direct manufacturing costs of the entire aircraft, dramatic reductions in aircraft engine costs must be achieved by design, economy of scale, and ...

The proposed PAVE propulsion system technology demonstration combines an innovative high-speed aero-diesel engine with a novel ducted fan assembly resulting in a low noise/cost and high performance propulsion system. The core engine makes extensive use of a novel self-injection, compression ignition/combustion system capable of high-speed operation on kerosene-based fuels without degradation due ...
