<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for reducing stress on a tip shroud of a rotary blade part used for a turbine rotor assembly. <P>SOLUTION: The rotor assembly includes a first turbine bucket 100. The firstturbine bucket includes a first tip shroud 212 extending from a radial direction outer end part 254 thereof. The first tip shroud includes a first surface 244. The rotor assembly includes a second turbine bucket 101. The second turbine bucket includes a second tip shroud 214 extending from a radial direction outer end part 255 thereof. The second tip shroud is arranged adjacent to the first tip shroud in a circumference direction. The second tip shroud includes a second surface 245 composed for transmitting at least part of radial direction loading induced at the second tip shroud to transmit to the first tip shroud, and at least part of radial direction loading induced at the first tip shroud to the second tip shroud. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
