LPE COMBUSTION CHAMBER MIXING HEAD Russian patent published in 2018 - 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. 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. On the bushings outer and inner rings output ends there are inclined or straight holes connected to the gaseous component supply channels. Holes are located in half of slots between the ribs. In the holes area, on the fuel supply side the slots are blocked by bridges. By the other half of the slots, the fuel comes to the channel end, cools down its wall, then turns in the groove and goes to the holes along the remaining slots.

EFFECT: invention provides increase in the LPE specific thrust impulse and the combustion chamber operation cost effectiveness.
