A gas turbine engine is provided to reduce load of engine for driving a fuel supply device and development cost, by driving a fuel injection device of an auxiliary combustor by a low pressure fuel supply device. A gas turbine engine comprises a compressor(100) for compressing intake air; a fuel supply device(430); a main combustor(200) for generating combustion gas by mixing compressed air supplied from the compressor and fuel supplied from the fuel supply device; a turbine(300) which has a driving shaft for driving the compressor by the rotating force obtained from the combustion gas generated from the main combustor, and discharges combustion gas generated from the main combustor; an auxiliary combustor(700) which is arranged at an end of the turbine where the combustion gas is discharged, and generates combustion gas by mixing the combustion gas discharged from the turbine and fuel supplied from the fuel supply device; and a fuel injection device which is arranged to rotate by the driving shaft extended from the driving shaft of the turbine, and injects fuel to the auxiliary combustor.
