Design of a high performance hydrocarbon liquid rocket engine (LRE) requires a thorough understanding of the heat transfer and cooling requirements of LRE's. An efficient cooling system is crucial in extending engine life and minimizing pumping power. Itis essential to be able to accurately calculate the thermal response to ensure that materials maintain structural integrity and the cooling chan ...

Combustion instability is one of the greatest development risks for liquid propellant engines. The risks arise in development of a stable injector design from a variety of sources - limited modelling capabilities, poor scalability and the high cost ofappropriate component test facilities. Sierra Engineering believes that much of the empirical data on the injection element's driving characteristic ...

An innovative tunable vibration absorber (TVA) concept was developed in the Phase I feasibility study. This design was selected among others to be developed in full scale in Phase II and Phase II Option based on a detailed theoretical modeling, smallprototype test results, and a cost analysis, which were conducted in Phase I.In Phase II and Phase II Option a new generation of TVA utilizing a clas ...

A study of the application for a visible light camera based on placing a Delta Sigma modulator at each pixel to provide per pixel A/D showed the potential for superior performance compared to alterate APS designs. It was demonstrated that substantiallyhigher fill factor and smaller pixel size could be achieved using common CMOS technology. Well capacity and linearity of the sensor were also shown ...

Ammonia is an attractive media for storing hydrogen for fuel cells because it exceeds 17% hydrogen by weight and leaves only nitrogen after decomposition and hydrogen removal. Safety questions related to the relatively high vapor pressure of ammonia canbe alleviated if ammonia is stored on an absorbent. Complex compounds are the best absorbents for ammonia, in that they have extremely high stora ...

DESCRIPTION (provided by applicant): The ability to evaluate the performance of seat cushions is critical to the development of wheelchair seating and standards, and to the selection of cushions by consumers and therapists. To assess the ability of a wheelchair cushion to distribute pressure, the Skeletal Embedded Loading Indentor (SKELI) was designed to simulate both the soft tissue and bony skel ...
