LIQUID-PROPELLANT ENGINE OF OPEN CONFIGURATION Russian patent published in 2012 - IPC F02K9/48 

FIELD: engines and pumps.

SUBSTANCE: liquid-propellant engine includes chamber, mixing head including external, intermediate and fire bottoms, which are attached to each other by means of oxidiser and fuel injectors, turbine-pump unit consisting of two single-step screw-centrifugal pumps, turbine the working body of which is generator gas generated in two-component gas generator fed from the main fuel components - oxygen and kerosene; besides, outlet pipe of waste generator gas after the turbine is connected to exhaust system; engine configuration includes thrust regulator and fuel components ratio throttle, which are installed on the corresponding main lines, in main oxygen line - liquid oxygen - between oxygen pump outlet and combustion chamber mixing head inlet of engine; gasifier representing a two-zone construction is installed; in addition, combustion is performed in the first zone at stoichiometric ratio of small quantities of oxidiser and fuel, and evaporation (gasification) of the main oxidiser flow is performed in the second zone at the flow being mixed with combustion products leaving the first zone, and in mixing head of chamber there arranged are spray gas injectors of oxidiser, which open to the head cavity that is connected to gasifier outlet.

EFFECT: stable combustion process in combustion chamber.
