AIR SPACE SYSTEM LAUNCH VEHICLE FIRST STAGE PROPULSION UNIT Russian patent published in 2004 - IPC

Abstract RU 2238422 C2

FIELD: spacecraft.

SUBSTANCE: proposed propulsion system of launch vehicle first stage is installed horizontally on board the booster craft and it contains propellant tank with hydrocarbon propellant and tank with cryogenic oxidizer-liquid oxygen. Tanks are connected by service mains of hydrocarbon propellant and liquid oxygen with liquid propellant rocket engine. Liquid oxygen service main passes inside hydrocarbon propellant tank and it is connected to bottom of cryogenic oxidizer tank furnished with inner cross partition. Said cross partition limits gas-liquid compartment in front part of tank. Lower part of gas-liquid compartment communicates with main volume of said tank filled with liquid oxygen. Liquid oxygen main passing inside hydrocarbon propellant tank is arranged with tilting downwards relative to longitudinal axis of launch vehicle. Invention prevents thermo starting of liquid oxygen in air-space system in flight.

EFFECT: improved reliability of air space system, increased mass of injected payload.
