PROPELLANT SUPPLY SYSTEM FOR SPACECRAFT ENGINE PLANT

摘要

space engineering. SUBSTANCE: system includes propellant tanks whose hydraulic cavities are connected with propellant supply manifold, start and shut-off valves and propellant tank pressurization system. Propellant feed system is provided with pups mounted in sections of mains between propellant tanks and start and shut-off valve separating hydraulic cavities of propellant tanks form propellant supply manifolds of jet engines. Low-pressure indicator is fitted in propellant supply mains before each pump; high-pressure indicator is fitted at pump outlet; these indicators are electrically connected with propellant supply system automatic control unit. EFFECT: reduced amount of high-pressure gas in propellant supply system of engine plant; improved mass and dimensional characteristics. 1 dwg
