Embodiment Construction
[0034] figure 1 is a simplified front elevation view of the rotor assembly 10 of the rotating machine with axis Ar. The rotor assembly includes a rotating structure as represented by a disk 12 , and a plurality of outwardly extending rotor blades 14 . Each rotor blade has a root 16 and an airfoil 18 disposed about a spanwise extending axis S commonly referred to as the stack line S. As shown in FIG. The airfoil has a pressure side 24 and a suction side 26 as shown in FIG. 3 . A flow path 22 for working medium gas extends through the rotor blade between the sides of the airfoil.
[0035] The rotor blade has a top region 28 with a top shroud 30 . The top cover comprises a sealing bead 32 which is a face with a radius of curvature around the axis Ar. The top shroud has a transition region 34 extending from the sides 24, 26 of the airfoil, as defined by figure 1 , Figure 4 and Figure 5 The pressure side 24 shown in; and the suction side 26 shown in Figures 4 and 6 represent...
