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. Cooled cylinder consists of several parts; at that, at least one part of cylinder is provided with possibility of radial axisymmetrical rotation about longitudinal chamber axis of liquid propellant engine and kinematically connected to power supply units, and on its external surface there installed are blades for bringing it into rotary movement. Inside the cooled cylinder, after the mixing head there installed axisymmetrically and with possibility of movement in mutually perpendicular planes is chamber of liquid-propellant engine with a converging-diverging nozzle; at that, nozzle cavity of this chamber opens to dish-shaped nozzle cavity.

EFFECT: simplifying pneumatic-hydraulic circuit and improving mass-and-dimensions characteristics.
