LIQUID-PROPELLANT ENGINE Russian patent published in 2019 - IPC F02K9/44 

FIELD: machine building.

SUBSTANCE: invention relates to the rocket engines building, and can be used in the design of liquid-propellant engines (LPE). LPE comprises combustion chamber with cooling path and mixing head, gas generator, turbo pump units of oxidiser and fuel, is characterized by that turbo-pump units are connected to each other by means of gas generator, which includes two chambers cooled by fuel components, on one of ends of each of which mixing head is fixed, consisting of fire bottom, housing and nozzles uniformly arranged along concentric circles, intermediate bottom located between mixing heads, wherein oxidative generator gas generated in one of gas generator chambers is supplied to turbine unit of oxidizer unit turbine, and the recovery generator gas generated in the other chamber of the gas generator is supplied to the inlet of the turbine of the turbo-pump fuel unit, besides, the outlets of the turbines of the turbine-pump units of the oxidiser and fuel are connected to the mixing head of the combustion chamber.

EFFECT: invention provides increase in the LPE energy characteristics and reliability.
