MIXER FOR INJECTOR HEAD OF LIQUID-PROPELLANT ENGINE CHAMBER Russian patent published in 2012 - IPC F02K9/52 

FIELD: power industry.

SUBSTANCE: mixer for injector head of liquid-propellant chamber consists of several bushings, which are installed coaxially and form ring-type cavities to supply gas fuel and liquid oxidiser. At each bushing there is collar with groves perpendicular to axis of mixer to supply fuel inside each ring-type cavity and with parallel groves to supply oxidiser to each ring-type cavity. From combustor chamber side ring-type cavities for supply of fuel components are closed with spacer plates with holes to supply fuel components to burning area, mainly to combustor chamber cavity, and all bushings are installed close to each other from side opposite to burning area. In end walls of bushings there are channels connecting oxidiser cavity with ring-type oxidiser cavities formed by installed bushings.

EFFECT: invention ensures maximum completeness of burning for different types of fuel with less number of mixers at injection head.
