MIXING HEAD OF GAS GENERATOR Russian patent published in 2019 - IPC F02K9/52 

FIELD: engines and pumps.

SUBSTANCE: invention relates to liquid-propellant rocket engines (LPRE), specifically to gas generators for generating gas for drive of turbo-pump unit. Mixing head of the gas generator contains a fuel unit, which includes the outer bottom, the inner bottom, on which fuel nozzles are evenly placed around the circles, representing the hollow tip, made in the output part to be deaf, the oxidizer unit, consisting of a body, oxidizer supply belts, which represent two concentrically interconnected bushings, on the outer surface of one of which longitudinal grooves are made, while the oxidizer supply belts, interconnected by means of rings, form annular channels, the internal cavity of which is connected to the fuel cavity by means of radial openings made on the cylindrical surface of the fuel nozzles, and with the oxidizer cavity through the openings made in the rings and located coaxially relative to the fuel nozzles.

EFFECT: invention provides improved homogeneity of the temperature field of the generating gas in a wide range of temperatures and pressures due to improving the quality of the mixture formation.
