FIELD: rocketry; liquid-propellant rocket engines.
SUBSTANCE: invention relates to liquid-propellant rocket engines operating on cryogenic oxidizer and hydrocarbon fuel. Proposed turbopump set of liquid-propellant rocket engine contains parts of rotor of turbopump set installed on shaft, impeller of oxidizer, pump, impeller of fuel pump and turbine wheel, and additional fuel pump with shaft and impeller of additional fuel pump arranged in housing of turbopump set. Magnetic clutch and step-up gear arte installed, according to invention, between turbine wheel and oxidizer pump impeller. Magnetic clutch and step-up gear can be installed between oxidizer pump and fuel pump. Magnetic clutch and step-up gear can be installed between fuel pump and additional fuel pump.
EFFECT: increased reliability of turbopump set.
