THROTTLEABLE OXYGEN-HYDROCARBON LIQUID-PROPELLANT ROCKET ENGINE WITH AFTERBURNING OF RECOVERY GAS Russian patent published in 2004 - IPC

Abstract RU 2238423 C2

FIELD: rocketry.

SUBSTANCE: proposed throttleable oxygen-hydrocarbon liquid-propellant rocket engine with afterburning of recovery gas has propellant mains, chamber cooled by hydrocarbon propellant, gas generator operating of oxygen-hydrocarbon propellant at excess of propellant, and propellant pumps driven by gas turbine. Engine control system includes thrust-control regulator and propellant component ratio control throttle, both installed in oxidizer mains. Device to create additional load for hydrocarbon propellant pump is used in operation control system at throttling conditions. Said device creating additional load for hydrocarbon propellant pump is made either as hydraulic resistance introduced directly into gas generator supply main or as bypass main with hydraulic resistance.

EFFECT: provision of serviceability of liquid-propellant rocket engines within wide throttling range, prevention of soot formation in gas generator.
