LIQUID-PROPELLANT ENGINE Russian patent published in 2012 - IPC F02K9/62 F02K9/52 

FIELD: engines and pumps.

SUBSTANCE: liquid-propellant engine includes annular chamber with mixing head and plate nozzle of external expansion, shaped central body and annular critical section. Control units and power supply units, which include turbine-pump unit with turbine, are located in cavity of shaped central body. The latter consists of several parts; at that, at least one part of shaped central body is provided with possibility of radial axisymmetrical rotation about longitudinal axis of shaped central body and kinematically connected to power supply units, and on its external surface there installed are blades for bringing it into rotary movement. Annular cavities for supply of fuel components on the side of combustion chamber cavity are covered with spacer plates in which there made are holes for supply of fuel components to combustion zone. On the side opposite to combustion zone the above cavities are covered with shaped bottom the inner surface of which is stepped; at that, at the bottom there made are radial and axial channels connecting fuel component supply cavities to the appropriate annular cavities.

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