LPE COMBUSTION CHAMBER MIXING HEAD Russian patent published in 2021 - IPC F02K9/52 

FIELD: rocketry.

SUBSTANCE: invention relates to the field of rocketry and can be used to create mixing heads for combustion chambers of liquid-propellant rocket engines (LPRE). The mixing head of the combustion chamber of a LPRE contains a housing in which longitudinal channels are made, connecting through tangential holes the fuel cavity formed by the housing and the bottom fixed at its end, with the internal cavity of the mixing head, and between the rows of tangential holes there are radial holes connecting the oxidizer cavity formed body and a collector of the oxidizer, with the internal cavity of the mixing head.

EFFECT: elimination of high-frequency vibrations due to stretching of the combustion region of fuel components along the longitudinal axis of the mixing head.
