US Patent 11371363 Turbine blade tip shroud surface profiles

A tip shroud may include a pair of opposed, axially extending wings configured to couple to an airfoil at a radially outer end thereof. The tip shroud also includes a tip rail extending radially from the pair of opposed, axially extending wings. Tip shroud surface profiles may be of the downstream and/or upstream side of the tip rail, a leading and/or trailing Z-notch of the tip shroud, and/or upstream and/or downstream radially outer surfaces of a wing. The surface profiles may have a nominal profile in accordance with at least part of Cartesian coordinate values of X, Y, Z and perhaps thickness, set forth in a respective table.
