LIQUID-PROPELLANT ENGINE Russian patent published in 2010 - IPC F02K9/64 

FIELD: engines and pumps.

SUBSTANCE: liquid propellant engine includes dish-shaped nozzle, annular combustion chamber with mixing head, which is located axisymmetrically inside the nozzle, and fuel and oxidiser supply headers; at that, combustion chamber is provided with shaped internal wall and located along longitudinal chamber axis. Inside combustion chamber there installed is cooled cylinder, one edge of which is connected to mixing head, and the other one - to central nozzle part and together with internal profiled wall of combustion chamber it forms an annular critical section. External wall of combustion chamber consists of several parts; at that, at least one part of external wall of combustion chamber is provided with possibility of radial axisymmetrical rotation about longitudinal axis of liquid propellant engine chamber and kinematically connected to power supply units; on its external surface there installed are blades for bringing it into rotary motion, and in outlet zone of fixed part adjacent to movable one there made are channels connected to supply system of combustible and opening to shaped surface of fixed part.

EFFECT: increasing specific burst of power, simplifying pneumatic-hydraulic circuit, and increasing pressure in chamber at minimum overall dimensions.
