LIQUID-PROPELLANT ENGINES CHAMBER MIXING HEAD Russian patent published in 2019 - IPC F02K9/52 

FIELD: engine building.

SUBSTANCE: invention relates to power plants of aircrafts, namely to mixing heads of liquid-propellant engines. Mixing head of chamber of liquid-propellant engine includes housing with cavities of components supply and belt for supply of components, connected to corresponding cavities of components by means of channels. Belts of components supply are made in the form of several coaxially installed shell rings located in relation to each other with annular gaps and forming closed annular cavities opening into combustion chamber. Annular cavities of fuel components uniformly alternate. On end faces 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 annular cavities. In the bottoms and cavities there are insulated channels connecting said end cavities through one to each other, at the same time the above annular cavities of fuel components are connected to the corresponding cavities of components supply through the above end cavities formed with profiled bottoms.

EFFECT: invention provides for simplification of design of mixing head with improved quality of mixture formation.
