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 ...

THERE IS A NEED FOR REFRIGERATION AS WELL AS HOT WATER HEATING ON MANNED SPACECRAFT. IN ORDER TO OBTAIN ENERGY ANDMASS EFFICIENT EQUIPMENT, IT IS PROPOSED TO USE COORDINATIVECOMPLEX COMPOUNDS, A SPECIAL CLASS OF NON-TOXIC SOLID-VAPOR MEDIA, FOR A DUAL DUTY THERMODYNAMIC CYCLE WHICH PROVIDES SIMULTANEOUSLY REFRIGERATION AND HOT WATER HEATING. SUCH CYCLES CAN BE DRIVEN WITH RELATIVELY LOW TEMPERATUR ...

ANALYTICAL METHODS AND COMPUTER SOFTWARE ARE TO BE DEVELOPED FOR CHARACTERIZING THE CHEMICAL KINETIC MECHANISMS THAT CONTROL LOX/HYDROCARBON COMBUSTION IN ROCKET ENGINES. CRITICAL AREAS OF TECHNOLOGY ARE TO BE IDENTIFIED. AN INNOVATIVE AND HIGHLY GENERAL METHOD WILL BEAPPLIED TO MODEL LOX/RP-1 COMBUSTION AS IT OCCURS IN GAS GENERATORS FOR PUMP FED ENGINES. THE METHOD WILL THEN BE EXTENDED TO MODEL ...

THE PRIMARY PURPOSE OF THIS PROJECT IS TO REDUCE THE REQUIREMENTS FOR INITIAL ALIGNMENT ACCURACY WHEN BRINGING A PAIR OF CONNECTORS TOGETHER PRIOR TO MATING THEM. THIS WILL BE ACCOMPLISHED BY INVESTIGATING THE USE OF A TAPERED OR CONICAL DESIGN TO INCLUDE A PRELIMINARY LATCHING FEATURE TO CAPTURE AND TO CAUSE ALIGNMENT OF A PAIR OF COMPLEMENTARY CONNECTORS. THE INVESTIGATION WILL TAKE INTO CONSIDE ...
