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 uniformly alternate 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, at that insulated channels are made in said bottoms and chambers to communicate said end cavities through one another. At that said fuel chamber annular cavities are communicated with appropriate cavities to feed components via said end cavities formed by profiled bottoms.

EFFECT: higher completeness of mix formation.
