COMBUSTION CHAMBER OF LIQUID-PROPELLANT ENGINE (LPE) WITHOUT GENERATOR Russian patent published in 2017 - IPC F02K9/62 F02K9/64 F23R3/42 F23R3/52 

FIELD: engines and pumps.

SUBSTANCE: combustion chamber of LPE, running on a non-generator circuit comprising of fuel and oxidizer supply lines, a chamber block with a supersonic nozzle, with the combustion chamber being annular in shape, parallel to the chamber block rigidly connected by an outer convex and inner curved body of the rotary device to the chamber block and the supersonic nozzle, and the cooling channel of the annular combustion chamber is connected by a cooling channel in the inner curved body of the rotary device to the cooling channel of the chamber block with the supersonic nozzle, and through the cooling channel in the outer convex bottom and through a pipeline the cooling channel of the annular chamber is connected to the pipeline at the outlet of the supersonic nozzle.

EFFECT: reducing the linear size of the engine, obtaining an additional set of heat to improve the engine's power characteristics and reducing the hydraulic resistance in the cooling channel of the engine.
