LPE COMBUSTION CHAMBER MIXING HEAD Russian patent published in 2019 - IPC F02K9/52 

FIELD: rocket equipment.

SUBSTANCE: invention relates to the field of rocket equipment and can be used in the construction of the liquid-propellant engines (LPE) combustion chambers mixing heads. LPE combustion chamber mixing head consists of a body with bushings made therein, gaps between which form the gaseous component supply annular channels. Mixing elements are fitted into said mixing head and secured at outlet ends of bushings. Bushings are interconnected by means of bypass channels. Each bushing consists of an outer and an inner rings, interconnected by evenly spaced inclined or straight ribs, between which the liquid component supply slots are located. Much of the liquid component is fed into the central bushings via one annular header, while the smaller part is fed into the peripheral bushing via the other annular header, at the inlet of which a tuning washer is installed.

EFFECT: invention provides higher reliability of cooling of combustion chamber and reduced cost and time of LPE.
