FIELD: engines.
SUBSTANCE: invention relates to low-thrust liquid-propellant engines (LTLPE). LTLPE comprising uncooled chamber 1, mixing head with inner bottom 2, centerline of swirler 3, peripheral zone of jet nozzles 4 and annular conical deflector 5 therebetween, wherein cut 6 of centrifugal nozzle is recessed from trailing edge 7, envelope surface of deflector to side peripheral zone jet nozzles 4 according to invention, cavity of combustion chamber 8 above outer surface of deflector 9 and cavity 10 at inner surface of baffle 11 and inner bottom of mixing head are interconnected channels 12.
EFFECT: invention provides high stability of operation of LTLPE, higher specific momentum and effective cooling of combustion chamber and mixing head.
