FIELD: astronautics.
SUBSTANCE: invention relates to rocket engineering, particularly, to organization of mixture formation of liquid-propellant engine of especially low thrust on self-igniting fuel components. Proposed chamber comprises mixing head with fuel feed channels with oxidizer and fuel spray nozzles communicated with sealed chambers made up of loop-like channels made of capillary tubes arranged in chamber cavity with jet nozzles at outlet directed to wedge mixer surface. According to the invention it is proposed to connect each injector directly to its fuel component supply channel and to place it in the ejection sprayer the gas cavity of which is interconnected with the capillary tube of the loop-like channel. Ejection sprayer can be made in the form of a channel coaxial with the jet nozzle, which is open from the injector nozzle side.
EFFECT: invention provides improved energy characteristics of low-thrust liquid-propellant rocket engines.
