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

FIELD: machine building.

SUBSTANCE: use: for mixing fuel components. Summary of invention consists in the fact that mixing head of liquid rocket 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 ends of shells on the side of inlet there are end profiled bottoms, attached to each other and to housing, and forming in-series arranged annular cavities, wherein in the bottoms and cavities there are insulated channels, the diameter of which decreases from the periphery to the center of the mixing head, connecting said end cavities through one to each other, wherein said annular cavities of fuel components are connected to corresponding cavities of supply of components through said end cavities formed by profiled bottoms.

EFFECT: higher completeness of mix formation.
