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 containing a housing in which annular channels are made, interconnected by longitudinal channels communicating with the fuel cavity formed by the housing and a bottom fixed at its end, and the internal cavity of the mixing head is connected to the annular channels by means of inclined holes, when in this case, rows of radial holes are located between the annular channels, connecting the inner cavity of the mixing head with the oxidizer cavity formed by the body and the oxidizer manifold, and the oblique and radial holes form triplet mixing elements.

EFFECT: invention ensures the stability of the combustion process of the fuel components due to the stretching of the combustion area along the longitudinal axis of the mixing head.
