LIQUID ROCKET ENGINE CHAMBER MIXING HEAD Russian patent published in 2019 - IPC F02K9/52 

FIELD: fuel mixing and supply systems.

SUBSTANCE: use: for mixture formation of fuel components. Summary of invention consists in the fact that withmixing head of liquid-propellant engine chamber includes housing with components supply cavities, components supply belts connected to corresponding cavities of components by means of channels, wherein components supply belts are made in the form of several coaxially installed shells located each relative to each other with annular gaps and forming closed annular cavities opening into combustion chamber, wherein annular cavities of fuel components are uniformly alternating between each other, at that on end faces of shells on the side of inlet there are end profiled bottoms fixed to each other and to the housing and forming serially located end annular cavities, wherein in the bottoms and bottoms there are insulated channels of different diameter, wherein the diameter of the channels decreases monotonically from the periphery to the center of the head, connecting said end cavities through one to each other, wherein said annular cavities of fuel components are connected to corresponding cavities of supplying components through said end cavities formed by profiled bottoms.

EFFECT: technical result is improved fuel mixture formation.
