MIXING HEAD OF LPE COMBUSTION CHAMBER Russian patent published in 2019 - IPC F02K9/52 

FIELD: rocket equipment.

SUBSTANCE: invention relates to the field of rocket equipment and can be used in the construction of the liquid-propellant engines (LPE) combustion chambers mixing heads. Mixing head of LPE combustion chamber includes housing, fire bottom and two-component gas-liquid injectors installed between them, characterized by that part of nozzles protrudes beyond fire bottom, forming radial partitions, and comprises inner and outer bushings installed coaxially and interconnected by means of ribs located on outer surface of inner bushing and between which there are grooves of liquid fuel component supply, at that, in half of slots located in the outlet part of the internal bushing, there are radial holes connected to the fuel component supply channel, wherein grooves are arranged in the area of slot holes on fluid fuel feed side while annular grooves connecting slots are made in inner bushing outlet part and in front of webs.

EFFECT: invention provides higher specific impulse of engine thrust due to higher quality of mixture formation.
