FIELD: mechanical engineering; engines. SUBSTANCE: proposed double-flow gas turbofan engine contains fan, high-speed compressor, combustion chamber, two-stage turbine setting compressor and fan into rotation, reaction nozzle and steam-water heater (steam generator). Engine is furnished also with air-hydrogen-nitrogen-oxygen heat-mass exchanger, reheat unit and multiplicator. Fan is made coaxial, double-row, sixteen-blade, variable pitch, with diameter of 3-3.4 m. Two-stage turbine is of combination impulse-reaction type, with de Laval nozzle fitted at its outlet. Higher-speed compressor is made with pressure ratio of Pc = 40, and speed of 6000-7600 rpm. Thrust of engine is 100 ton, air flow rate through first contour being 400 kg/s and through second contour, 1000 kg/s and gas temperature before turbine equal to 1800 K. EFFECT: increased efficiency of engine. 8 cl
