LIQUID-PROPELLANT ENGINE CHAMBER MIXING HEAD Russian patent published in 2012 - IPC F02K9/52 

FIELD: engines and pumps.

SUBSTANCE: mixing head of liquid-propellant engine (LPE) chamber includes housing, oxidiser supply unit, fuel supply unit, injectors consisting of several coaxially installed sleeves forming annular cavities for supply of fuel and oxidiser, which are installed in mixing head along concentric circles and connect the cavities of units to the cavity of combustion chamber. Annular cavities for supply of fuel components on the side of combustion chamber cavity are covered with spacer plates in which there made are holes for supply of fuel components to combustion zone, and on the side opposite to combustion zone the above cavities are covered with shaped bottom the inner surface of which is stepped. At the bottom there made are radial and axial channels connecting the fuel component supply cavities to the appropriate annular cavities.

EFFECT: higher combustion efficiency of fuels of various types at smaller number of mixing elements on injector head of the chamber.
