JET CENTRIFUGAL SPRAYER 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). Jet-centrifugal nozzle includes the housing consisting of two cylinders of different diameters, which are interconnected with the formation of an annular step, formed by the end of a larger cylinder. In the housing there is a central axial profiled channel with expanding and cylindrical parts interconnected with the formation of an internal ledge, and tangential channels connecting the cavities of the components with the cavity of the combustion chamber and the nozzles opening into the mixing cavity. Output parts of the tangential channels are located on the inner ledge of the output section of the expanding part of the central channel of the nozzle in such a way that the projections of the longitudinal axes of any two diametrically opposite tangential channels when they are 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 mentioned 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 optimal conditions for mixing the gas and the liquid component in the nozzle.
