METHOD OF STARTING OF OXYGEN-HYDROCARBON PROPELLANT ROCKET ENGINE WITH AFTERBURNING Russian patent published in 2003 - IPC

Abstract RU 2204733 C2

FIELD: rocket engines. SUBSTANCE: according to proposed method, oxygen is fed into gas generator through intake main line and pump of turbopump set at higher pressure from propellant tank when starting valve installed in intake main line is opened and main oxygen valve installed after pump of turbopump set is initially closed. Main oxygen valve is opened before oxygen gets to valve. Invention makes it possible to decrease losses of liquid oxygen for prestarting chilling of engine. EFFECT: improved reliability of starting of liquid-propellant rocket engine.
