FIELD: engines and pumps.
SUBSTANCE: proposed engine chamber combustion chamber with regenerative cooling, throat and nozzle, mixing head including housing, unit to feed oxidiser, mainly, oxygen, primary fuel feed tank, extra fuel feed tank and fire bottom unit. Coaxial aligned-jet nozzles making central and peripheral zones are arranged in said units in concentric circles. Said coaxial aligned-jet nozzles include hollow tip communicating oxidiser zone with fire zone, sleeve covering said tip with clearance to communicate the primary fuel unit with fire zone. Note here that tips of at least central zone nozzles have radial grooves at their outlets composed of alternating ledges and recesses. Note also that the sleeve between tip ledges has channels with outlets open to fire zone and inlets communicated with extra fuel unit chamber. Note that outer profile of said channels is equidistant with tip profile.
EFFECT: higher efficiency of combustion.
