DEVICE FOR TRANSFER OF GAS IN PROPELLANT TANK PRESSURIZATION SYSTEM OF SPACECRAFT ENGINE PLANT

摘要

FIELD: space engineering. SUBSTANCE: device includes gas-filled container with on-board compressor located inside it. Compressor is connected with pressurizing bottles by means of high-pressure pneumatic mains and with gas cavities of respective fuel and oxidizer tanks by means of low-pressure pneumatic mains. Pneumatic mains are fitted with valves. Container is provided with finned heat-conducting jacket. Cavity between container body and jacket is filled with heat absorbing material and is brought in communication with compensator arranged in container. Body of container is connected with compressor casing by means of perforated diaphragm made from heat-conducting material. EFFECT: enhanced efficiency of cooling the on-board compressor; high survivability; enhanced reliability. 1 dwg
