FIELD: jet engine plants of spacecraft. SUBSTANCE: system consists of autonomous subsystems including propellant tanks whose hydraulic cavities are connected with propellant supply manifolds of group of control jet engines by means of propellant supply mains connected to start and cutout valves fitted at inlets of manifolds. Subsystems are interconnected by means of propellant transfer hydraulic mains through coupling units; propellant transfer mains are connected to mains supplying propellants from tanks to manifolds through start and cutout valves. Propellant supply system includes also additional mains for discharge and delivery of propellant components fitted with start and cutout valves connecting the engine supply manifolds in each autonomous subsystem with propellant transfer hydraulic mains; on one side, additional mains of subsystems are connected to inlets on manifolds after start and cutout valves fitted at manifold inlets and on other side, they are connected to propellant transfer hydraulic mains between start and cutout valves. EFFECT: probability of redistribution of propellant among manifolds of jet engines; enhanced reliability; improved energy and mass characteristics during space flight. 1 dwg
