FIELD: engines and pumps.
SUBSTANCE: proposed method consists in feeding fuel components in combustion chamber via coaxial aligned-jet nozzle communicating oxidiser chamber with combustion zone and including sleeve covering with clearance the nozzle to communicate fuel zone with combustion zone arranged in mixing head in concentric circles to make central and peripheral zones. At first-stage mode, oxygen is fed in combustion chamber via nozzle with developed outlet surface of coaxial aligned-jet nozzle. Hydrogen is fed via shape clearance between aforesaid nozzle and sleeve while kerosene is fed via channels made in said sleeve. Note here that outlet profile of said channels is equidistant to nozzle profile. Note also that outlet part of said channels opens into combustion chamber while inlet part communicates with kerosene unit chamber. At second-stage mode and that of other stage, oxygen is fed in combustion chamber via hollow nozzle with developed outlet surface of coaxial aligned-jet nozzle. Hydrogen is fed via shaped clearance between nozzle and said sleeve.
EFFECT: better fuel mix mixing.
