Abstract
A method and apparatus for fabricating a rotor assembly for a turbine is provided. The method includes forming a cover on each bucket radial tip wherein the cover includes a leading edge side in a direction of rotation, and a trailing edge side in the direction of rotation wherein the leading edge and trailing edges are parallel with respect to each other, and wherein the leading edge and trailing edges are skewed with respect to the axis of rotation. The method includes forming an extension in the cover leading edge side, forming a groove in the cover trailing edge side, and attaching each bucket to the radially outer rim, such that the extension in the cover leading edge side of one cover is in mating engagement with the groove in the cover trailing edge side of an adjoining cover.
