Abstract
A method for fabricating a rotor blade is provided. The method includes providing a rotor blade that includes a tip shroud having a portion of increased cross-sectional thickness relative to adjacent portions of the tip shroud. The increased cross-sectional thickness section extends across substantially an entire circumferential width of the tip shroud. The increased cross-sectional thickness section defines a pair of opposite interlock surfaces that each form a portion of a respective side of the pair of opposite tip shroud sides used for interlocking the tip shrouds of two adjacent rotor blades on the rotor. The method also includes removing a portion of the increased cross-sectional thickness section between the pair of opposite tip shroud sides to facilitate enhancing the efficiency of the rotor blade.
