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

FIELD: motors and pumps.

SUBSTANCE: invention relates to liquid-propellant rocket engines, specifically to gas generators for generating gas for the turbopump unit drive. Gas generator comprises fuel-cooled chamber, mixing head including housing, on the ends of which the upper and lower bottoms are fixed, mounted on the housing oxidizer manifold, and evenly spaced around the circumference nozzles, including tubular body, in which input part radial holes are made, tip with helical channels installed inside the tubular body, and bushing installed on the tubular body with the annular gap and forming the oxidant supply annular channel, connected to the oxidant cavity by formed in the bushing wall tangential holes, at that, the tip axial channel is connected to the fuel cavity and the chamber cavity, wherein the chamber cooling path cavity is connected to the mixing head fuel cavity.

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.
