GAS GENERATOR Russian patent published in 2018 - IPC F02K9/64 

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. Gas generator contains a chamber and a mixing head, which includes a housing with a collector, belts for supplying the excess fuel component, installed coaxially in the mixing head and consisting of two bushings concentrically interconnected, on the outer surface of one of which grooves are made, with the belts interconnected to each other and the casing by means of annular mixing elements, in which fuel supply holes are made, the axes of which intersect, form annular channels, and the collector cavity is connected to the cavities of the belts by means of channels made in annular mixing elements, a bottom fixed on the end of the body.

EFFECT: invention provides increase in the generator gas temperature field and the pressures uniformity at the outlet due to the improvement in the mixture formation quality and the gas generator design optimization.
