SPACE VEHICLE ENGINE PLANT FUEL-FEED SYSTEM Russian patent published in 2001 - IPC

FIELD: aeronautical engineering. SUBSTANCE: proposed fuel-free system of space vehicle engine plant has fuel tanks with starter-and-cutoff valves, fuel feed manifold of control rocket engines with feed valves and fuel feed main lines connected with starter-and-cutoff valve by cross-feeding pipeline. Fuel-feed system is provided additionally with two cross-feeding main lines with valves uniting tanks and fuel feed manifolds. One additional cross-feeding main line is connected before starter-and-cutoff valve at furl tank outlet, and the other is connected after feed valves before inlet in fuel-feed manifold of control rocket engines. EFFECT: improved performance characteristics of engine plant owing to provision of serviceability of fuel-feed system in case of violation of tightness in fuel main lines and cross-feeding pipelines at long operation in space flight. 1 dwg
