FIELD: engine building.
SUBSTANCE: invention relates to liquid-propellant rocket engines. Mixing head of liquid-propellant rocket engine chamber includes external bottom, two-component nozzles fixed in housing and fire bottom, ignition device and underwater lines of fuel and oxidizer, wherein peripheral part consists of two rings interconnected in end part wall with holes, forming annular gas cavity, in walls of which there are small holes 0.5÷1.2 mm at distance between each other from 2 to 5 gages, connecting it through the reservoir cavity with an independent fuel supply main line, and central part comprises two-component nozzles, fixed in housing and fire bottom, which cavities are connected through cavities of headers to main lines supplying oxidizer and fuel, and center thereof is a backhaul line.
EFFECT: higher reliability and power characteristics.
