GAS GENERATOR Russian patent published in 2018 - IPC F02K9/62 

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 two combustible cooled combustion chambers, two mixing heads, consisting of a body, on the end of which there is a firing bottom, at the same time, the firing bottoms of the mixing heads are located symmetrically with respect to the oxidant collector located between the bodies of the mixing heads, single-component centrifugal nozzles of the oxidizer and single-component jet-centrifugal fuel nozzles connecting the cavity of the fuel components of the mixing heads with the internal cavity of the combustion chamber, moreover, six fuel nozzles are located around each oxidizer nozzle, and the cooling path of the combustion chamber is connected to a fuel cavity of a mixing head.

EFFECT: invention provides higher homogeneity of the temperature field of generator gas at the outlet in a wide range of temperatures and pressures by improving the quality of mixture formation.
