Abstract
Body wedge blocks are provided adjacent the end of the rotor body that have a forward facing axial end that is aerodynamically streamlined. Thus, between adjacent body wedge blocks a flow passage for cooling air is created that allows gradual contraction of the flow from the endwinding region toward the subslot ducts, thereby reducing pressure losses.
