METHOD OF OPERATION OF CLOSED CYCLE LIQUID ROCKET ENGINE WITH AFTERBURNING OF OXIDIZING AND REDUCING GENERATOR GASES WITHOUT COMPLETE GASIFICATION AND LIQUID ROCKET ENGINE Russian patent published in 2023 - IPC F02K9/50 

FIELD: rocket and space technology.

SUBSTANCE: proposed group of inventions relates to the design of liquid rocket engines. The invention discloses the use of a scheme with two gas generators and afterburning of reducing and oxidizing generator gases without complete gasification. The non-gasified residue is fed into heat exchangers and used to pressurize the fuel tanks, which increases the payload mass by reducing the mass of the tank pressurization systems and reduces the overall cost of the installation.

EFFECT: invention provides increased efficiency of a high thrust rocket engine and high payload.
