FIELD: refrigerating engineering, in particular, air cooling turbine plants. SUBSTANCE: at a running engine the atmospheric air through the air-intake duct is fed to the blowing cavity of the heat exchanger, where it is heated in the process of heat exchange with the cooled high-pressure air. After the heat exchanger the blowing air gets compressed with a temperature rise in the brake compressor and is fed through the delivery pipe-line to the engine by-pass duct. To enhance the economical efficiency, part of the blowing air past the heat exchanger may be directed to the cooling system of the engine exhaust nozzle. EFFECT: enhanced efficiency, since the blowing air having a high energy potential after heating in the heat exchanger and compression in the brake compressor, is used in the engine operating processes. 9 cl, 1 dwg
