METHOD OF OPERATION OF LIQUID-PROPELLANT ROCKET ENGINE AT TURBOPUMP DELIVERY OF OXYGEN-METHANE PROPELLANT Russian patent published in 2001 - IPC

Abstract RU 2166661 C1

FIELD: rocketry. SUBSTANCE: methane fuel delivered to engine is consumed in the amount of 20 to 50% for regenerative cooling of chamber after which it is burnt in this chamber and oxygen oxidizer is partially fed directly to chamber and partially to gas reducing gas generator where excessive fuel fed at pressure higher than initial pressure of cooling agent is burnt in oxidizer; reducing gas thus obtained is used for operation of turbine after which it is finally burnt in chamber. EFFECT: enhanced efficiency; possibility of afterburning of reducing gas in chamber at high pressure making it possible to realize high specific thrust impulse. 2 dwg
