Spatial uniformity within combustion devices, especially circumferential, is extremely important to the reliability and durability of a liquid rocket engine. Conventional combustion diagnostics, e.g. pressure and thrust, characterize global engine behavior, but provide no direct information about thermal and species distributions across the engine. Sierra Engineering has shown that exhaust plume m ...

CRYOPRESERVATION OFFERS THE OPPORTUNITY TO STORE EMBRYOS AND LARVAE OF THE HARD CLAM, MERCENARIA MERCENARIA, FOR EXTENDED PERIODS WITH NEGLIGIBLE LOSSES. OBJECTIVES FOR PHASE I RESEARCH INCLUDE (1) TO DETERMINE THE EFFICACY OF SELECTED CRYOPROTECTANTS IN PRESERVING AND STORING 2-8 CELL EMBRYOS, (2) TO DETERMINE SURVIVAL AND DEVELOPMENTAL COMPETENCY OF 2-8 CELL EMBRYOS, TROCHOPHORE AND VELIGER LARV ...

Adsorption refrigeration using ammoniated complex compounds as the absorbent media can be used for miniature portable blast freezers. This is possible because the technology allows low evaporator temperatures without staging, is scalable to small sizes, and has high reliability because the only moving parts are check valves. Compared to vapor compression or other sorption refrigeration systems, th ...

This proposal outlines the design and development of a uniflow two stroke Aero-Diesel engine core in response to the NASA SBIR solicitation for a general aviation aircraft propulsion system. The proposed engine will offer increased power density, simplified operation, reduced emissions, noise, and vibration, while enhancing reliability and safety when compared to currently available general aviati ...
