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

FIELD: engines and pumps.

SUBSTANCE: liquid-propellant engine includes dish-shaped nozzle, annular chamber with mixing head, which is located axisymmetrically inside the nozzle, and fuel and oxidiser supply headers. At that, combustion chamber is provided with internal profiled 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 cover of annular ombustion chamber consists of several parts. At that, at least one part of external cover is provided with possibility of radial axisymmetrical rotation about longitudinal chamber axis of liquid-propellant engine and is kinematically connected to power units. On its external surface there installed are blades for giving rotational movement to it. And inside the cooled cylinder, after the mixing head there installed axisymmetrically and with possibility of movement in mutually perpendicular planes is liquid-propellant engine with a converging-diverging nozzle; at that, nozzle cavity of this engine opens to dish-shaped nozzle cavity.

EFFECT: increasing specific burst of power and simplifying the control of power vector.
