INJECTOR HEAD OF THE LRE CHAMBER Russian patent published in 2019 - IPC F02K9/52 

FIELD: rocket equipment.

SUBSTANCE: invention can be used to create nozzle heads for chambers of liquid rocket engines (LRE). Injection nozzle head of the LRE chamber includes the head body and the firing bottom with jet-centrifugal nozzles installed in them, having central axial profiled and tangential channels made in the body of each nozzle connecting the cavities of the components to the cavity of the combustion chamber. Tangential channels are arranged in such a way that the projections of the longitudinal axes of any two diametrically opposite channels when projected onto a plane passing through the longitudinal axis of the nozzle and parallel to it, form an obtuse angle at the apex, while the aforementioned apex is located on the longitudinal axis of the nozzle.

EFFECT: invention provides for an increase in the specific impulse due to the provision of optimum conditions for mixing the gas and the liquid component.
