A turbine moving blade cascade 30 of a turbine rotor assembly 35 has root portions of plural moving blades 13 fitted and held in a root groove circumferentially formed 5 on the outer circumferential portion of a rotor disk 15 of a turbine rotor 14 and has a notch blade 40 fixed in a cutout portion formed in the rotor disk 15. The plural moving blades 13 are comprised of three types of moving blades which include regular blades 50 having a 10 circumferential width determined through theoretical calculation, wide blades 51 having a circumferential width larger than the regular blades 50, and narrow blades 52 having a circumferential width smaller than the regular blades 50. 25946641 (GHMatters) P86270.AU 8103/11 15 14a |
