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

FIELD: engines and pumps.

SUBSTANCE: liquid propellant engine (LPE) includes annular chamber with mixing head, plate nozzle of external expansion, shaped central body and annular critical section, which are formed with shaped internal and external covers attached to each other along cooling circuit ribs. Control units and power supply units, which include turbine-pump unit with turbine, are located in cavity of shaped central body. In shaped covers of combustion chamber there made is at least one channel passing through cooling circuit the cavity of which is interconnected on one side with cavity of combustion chamber, and on the other - with inlet cavity of turbine of turbine-pump unit; at that, supply pipeline of one of fuel components opens to the channel cavity.

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