FIELD: engines and pumps.
SUBSTANCE: combustion chamber houses two or three rows of nozzles. Stoichiometric fuel combustion occurs in the first and/or extra row of said nozzles. "Atmofuel" is forced to the second row of nozzles in the amount sufficient for cooling of gas downstream of the first row to the level acceptable for turbine. Thereafter, evaporated fuel is burnt in afterburner chamber in the mix with air of the engine second stage. Extra amount of fuel is injected into "atmofuel" nozzles and/or afterburner chamber nozzles to be combusted completely in the mix with the turbine second stage air.
EFFECT: higher thrust, expanded adjustment range.
