PROBLEM TO BE SOLVED: To provide a turbine disk of a gas turbine engine having such a shape that changes empty air stream due to a profile shape of a conventional disk slot abruptly and capable of overcoming defect such as pressure loss of an inlet caused by an inlet. SOLUTION: This gas turbine engine includes a compressor section, a combustion section arranged on the downstream side of the compressor section, and a turbine section arranged on the downstream side of the combustion section. The turbine section is provided with the turbine disk for defining a plurality of turbine disk slots for storing a turbine blade. Each of the plurality of turbine disk slots is provided with an inlet having an outer peripheral part being like a curved line and having a round corner in a bottom part. COPYRIGHT: (C)2007,JPO&INPIT
