PROBLEM TO BE SOLVED: To provide an incorporation method for a turbine rotor blade for incorporating a turbine rotor blade body at a narrow pitch, the turbine rotor blade and a turbine with the turbine rotor blade.;SOLUTION: In this incorporation method for the turbine rotor blade, the turbine rotor blade body including a blade root inserted in each of a plurality of grooves formed in the circumferential direction of a turbine disk and engaged therewith, and a blade imparting the energy of rotary motion to the turbine disk, and a platform supporting the blade root and the blade is incorporated in the turbine disk. The turbine rotor blade has a plurality of kinds of turbine rotor blade bodies having platforms having different shapes, and the blade root of the turbine rotor blade boy having a prescribed platform shape is inserted in the groove in a prescribed order to the turbine disk to perform incorporation.;COPYRIGHT: (C)2008,JPO&INPIT
