Abstract
A turbine bucket that may include an airfoil having a tip shroud, the tip shroud having an edge; wherein the edge has a profile substantially in accordance with values of X and Y in a Cartesian coordinate system set forth in Table 1 at points 1-14, wherein X and Y represent distances that may be proportionally scaled by a common multiplier which, once scaled and connected, define the profile of the edge of the tip shroud.

A turbine bucket including an airfoil having a tip shroud, the tip shroud having an edge;
- wherein the edge has a profile substantially in accordance with values of X and Y in a Cartesian coordinate system set forth in Table 1 at points 1-14, wherein X and Y represent distances that may be proportionally scaled by a common multiplier which, once scaled and connected, define the profile of the edge of the tip shroud.
A turbine bucket including an airfoil having a tip shroud, the tip shroud having an edge;
- wherein the edge has a profile substantially in accordance with values of X and Y and Z in a Cartesian coordinate system set forth in Table 1 at points 1-14, wherein X and Y and Z are distances in inches which, when the points are connected by smooth, continuing arcs, define the profile of the edge of the tip shroud.
A tip shroud for a turbine bucket, the tip shroud having a leading edge and a trailing edge, wherein the profile of the leading edge is defined substantially in accordance with values of X and Y in a Cartesian coordinate system at points 1-14 as set forth in Table 1, wherein the X and Y values are distances in inches which, when the points are connected by smooth, continuing arcs, define the profile of the leading edge of the tip shroud.
