FIELD: fuel.
SUBSTANCE: invention is intended for organizing of mixing and combustion of self-igniting fuel in the low-thrust liquid-propellant rocket engines (LTLPRE) operating in vacuum. Device consists of pre-chamber 1 and combustion chamber 2. In said pre-chamber 1 there are channels 3 for fuel components supply, and there is also profiled surface 4 with sharp edge 5. Fuel feed channels are located in plane perpendicular to axis of the pre-chamber, end of each channel is connected tangentially with profiled surface, shape of which is a circular arc, wherein the surface is finished with a sharp edge in the cavity of the pre-chamber.
EFFECT: invention provides conversion of liquid jets of fuel and oxidizer into finely dispersed, vapor-phase state in which fuel and oxidizer interact maximum active.
