METHOD OF FUEL COMPONENTS FEED IN THREE-COMPONENT LIQUID PROPELLANT ROCKET ENGINE COMBUSTION CHAMBER

摘要

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. Note here that at first stage mode oxygen is fed into combustion chamber via hollow nozzle with developed outlet surface of aligned-jet nozzle while hydrogen is fed via shaped gap between said nozzle and said sleeve and kerosene is fed via channels made in said sleeve. Note also that outlet section of said channels opens into combustion chamber while their outlet communicates with kerosene unit chamber. In operation at second and further stages oxygen is fed into combustion chamber via nozzle with developed outlet surface of aligned-jet nozzle while hydrogen is fed via shaped gap between said nozzle and said sleeve.EFFECT: better fuel mix mixing.2 dwg
