FIELD: gas-turbine engines.
SUBSTANCE: proposed gas-turbine engine with turbocooler at inlet contains turbocompressor with compressor, main combustion chamber and turbine with two series mounted fuel-air heat exchangers. First fuel-air heat exchanger is located in channel of gas-air duct at turbocompressor inlet. Turbocooler turbine arranged between fuel-air heat exchangers along fuel line is mechanically connected with power consumer(s).
EFFECT: increased cold0retaining capacity of fuel, increased degree of utilization of waste energy in gas-turbine engine.
