GAS TURBINE ENGINE

A gas turbine engine in which a compressor, a combustor, and a turbine are arranged so as to be lined up along a rotating shaft includes: a casing that accommodates the compressor, the combustor, and the turbine; fuel pump units that are arranged at an outside of the casing, are lined up in a circumferential direction along an outer peripheral surface of the casing, and are connected in parallel; and a fuel supply pipe that collects fuel discharged from the fuel pump units and supplies the fuel to the combustor.
