LIQUID ROCKET ENGINE WITH AFTERBURNING Russian patent published in 2022 - IPC F02K9/66 F02K9/48 

FIELD: liquid rocket engines.

SUBSTANCE: invention relates to liquid rocket engines with afterburning. A liquid-propellant rocket engine with afterburning, containing an engine compartment with a support frame with the possibility of swinging in one of the stabilization planes, a turbine of a turbopump unit operating with an excess of one of the components, with a behind-turbine cavity connected to a gas duct of a chamber with a minimum cross section and an outlet section of a nozzle equipped with a supply manifold in the cooling path of the chamber of one of the components missing in the turbine, connected to the support frame, in which the housing of the turbopump unit with its cylindrical section is placed with its longitudinal axis of symmetry at an acute angle to the longitudinal axis of symmetry of the engine, for example 40-45°, in a plane parallel to the longitudinal axis of the engine with placement in the sector space of the cavity of the engine compartment from the outer part of the minimum section of the nozzle with the minimum distance between the longitudinal axes of symmetry of the chamber and the turbopump unit, and the housings of the chamber and the turbopump unit - with a gap without touching them with each other.

EFFECT: invention provides reduction of inertia of the engine with afterburning relative to the swing axis, radial dimensions and mass of the liquid-propellant rocket engine.
