FIELD: aircraft engine engineering. SUBSTANCE: area of the critical section of nozzle sets of the turbine is preliminary increased by up to 30% Speed of rotation of the engine is in 0.90-0.97 of the maximum value. Steam is fed to the engine combustion chamber in the amount of 10-35% of total air and fuel flow rate, the temperature being decreased upstream of the turbine by up to 20% and decreased pressure downstream of the compressor by up to 10% The steam is obtained by evaporating water in the steam generator with heat released by exhaust gases. The exhaust gases is purified in the heat-exchanger-condenser by creating counterflow of the condensate film which flows down over cold walls and upward gas flow. The water condensate obtained is separated from the gas flow, filtered, neutralized, and turned back to the steam generator forcedly. EFFECT: enhanced efficiency. 6 cl, 2 dwg
