TURBINE BLADE TIP SHROUD SURFACE PROFILES
A tip shroud (220) includes a pair of opposed, axially extending wings (232, 234) configured to couple to an airfoil (202) at a radially outer end (222) thereof. The tip shroud (220) also includes a tip rail (250) extending radially from the pair of opposed, axially extending wings (232, 234). Tip s...

| description | A tip shroud (220) includes a pair of opposed, axially extending wings (232, 234) configured to couple to an airfoil (202) at a radially outer end (222) thereof. The tip shroud (220) also includes a tip rail (250) extending radially from the pair of opposed, axially extending wings (232, 234). Tip shroud surface profiles may be of the downstream side (254) and/or upstream side (252) of the tip rail (250), a leading Z-notch (276) of the tip shroud (220), and/or a downstream radially inner surface (242) of a wing (234). The surface profiles may have a nominal profile substantially in accordance with at least part of Cartesian coordinate values of X and Y, and perhaps Z and a thickness, set forth in a respective table. The radially inner surface (242) of the wing (234) may define a protrusion (282) extending along the radially outer end (222) of the airfoil (202), the suction side fillet (280), and a radial inner surface (242) of the wing (234) to an axial edge (284) of the wing (234). |
