METHOD OF FEEDING THREE-COMPONENT FUEL INTO LIQUID-PROPELLANT ROCKET ENGINE CHAMBER Russian patent published in 2013 - IPC F02K9/42 

FIELD: engines and pumps.

SUBSTANCE: proposed method of feeding three-component liquid-propellant engine, mainly, oxygen-kerosene-hydrogen, consists in feeding said components into combustion chamber via aligned jet atomisers. Said atomizers comprise hollow nozzle connecting oxidiser chamber with combustion zone and sleeve covering said nozzle with clearance to communicate fuel chamber with combustion zone, both being arranged in mixing head in concentric circles to make central and peripheral zones. In first-stage mode, oxygen is fed into combustion chamber via said hollow nozzle with developed exit surface of aligned jet atomiser. Hydrogen is fed via shaped clearance between nozzle and sleeve of aforesaid atomiser. Kerosene is fed via sleeve channels. Note here that outlets of said channels open into combustion chamber. Their inlets are communicated with kerosene chamber. In first-stage mode, oxygen is fed into combustion chamber via said hollow nozzle with developed exit surface of aligned jet atomiser. Hydrogen is fed via shaped clearance between nozzle and sleeve of aforesaid atomiser.

EFFECT: higher efficiency of mixing.
