PROPELLANT FEED SYSTEM FOR ENGINE PLANT OF ORBITAL SPACE COMPLEX Russian patent published in 2000 - IPC

FIELD: jet engine plants of spacecraft. SUBSTANCE: proposed system includes autonomous propellant feed system and replenishing system which are connected by propellant- transfer lines through joint units. System is provided with electric heaters mounted in autonomous system in sections of hydraulic lines between joint units and start-and-cut-off valves and propellant vapor absorbent reservoirs mounted in replenishing system and connected through start- and-cut-off valves in sections of propellant-transfer lines and start-and- cut-off valves; reservoirs are provided with drainage valves. EFFECT: avoidance of emissions of propellant into space in disconnecting the lines and cleaning them before uncoupling. 1 dwg
