FIELD: engines.
SUBSTANCE: invention relates to liquid-propellant engines. Rocket engine fuel supply system, comprising fuel supply circuit (4), additionally comprises a device for varying volume of gas in circuit (4), configured to vary volume of gas in circuit during operation of rocket engine. Also disclosed is a method for eliminating the POGO effect by varying at least one hydraulic resonant frequency (50) by varying rate at which gas is injected into circuit (4), a vehicle and a computer-readable data medium.
EFFECT: invention provides suppression of process of entering into resonance of liquid fuel in fuel supply circuit in rocket engine.
