<P>PROBLEM TO BE SOLVED: To provide an arrangement and a method for mounting an articulated turbine bucket in an axial entry slot of a rotor wheel. <P>SOLUTION: A curvature on a vertical plane may be incorporated on an axial male dovetail projection of the bucket root and the associated axial female dovetail slot of the rotor wheel. The curvature facilitates loading of buckets otherwise precluded by interferences, such as interlocking tip shrouds on adjacent buckets. Such loading may be provided by locating the shroud tip shroud in proximity to an adjacent tip shroud and pivoting the root end of the bucket around the location of the tip shroud such that the arc formed by the bucket allows the curvature of the axial male dovetail projection to swing into the axial female dovetail slot of the rotor wheel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
