FIELD: mechanic, energetic. ^ SUBSTANCE: the invention relates to power plants of aircraft, namely, to mixer heads of rocket liquid propellant systems. The mixer heads of a rocket liquid propellant system contains a shell with a collector, the cavity of which is connected to liquid component feeding belts designed as a hollow spiral of Archimedes with a profiled cross-section and with holes in the output part, for feeding the liquid component into the combustion chamber cavity; the circular slots for feeding the liquid component are formed by the spiral turns. The invention provides decreasing of hydraulic resistance and increasing of the fuel speed, and regular distribution of the fuel. ^ EFFECT: provides decreasing of hydraulic resistance and regular distribution of the fuel. ^ 1 cl, 2 dwg |
