A turbine rotor blade including an airfoil having a tip shroud, the tip shroud having leading and trailing edges, the leading edge having a leading edge profile including first and second scalloped sections substantially in accordance with X and Y coordinate values in a Cartesian coordinate system at points 1-6 and 11-25, respectively, as set forth in Table I, where X and Y are distances in inches from an origin and, when points 1-6 and points 11-25 are connected by smooth, continuing arcs, the points define the first and second scalloped sections, respectively, of the leading edge profile of the tip shroud.
A turbine rotor blade including an airfoil having a tip shroud, the tip shroud having leading and trailing edges, the leading edge having a leading edge profile including first and second scalloped sections substantially in accordance with X and Y coordinate values in a Cartesian coordinate system at points 1-6 and 11-25, respectively, as set forth in Table I, where X and Y are distances in inches from an origin and, when points 1-6 and points 11-25 are connected by smooth, continuing arcs, the points define the first and second scalloped sections, respectively, of the leading edge profile of the tip shroud.
A turbine rotor blade including a rotor blade airfoil having a tip shroud, the tip shroud having leading and trailing edges, wherein the trailing edge comprises a trailing edge profile substantially in accordance with X and Y coordinate values in a Cartesian coordinate system at points 47-68, as set forth in Table I, where X and Y are distances in inches from an origin and, when points 47-68 are connected by smooth, continuing arcs, the points define the trailing edge profile of the tip shroud.
A turbine rotor blade including a rotor blade airfoil having a tip shroud, the tip shroud having leading and trailing edges and first and second Z-form edges, the first Z-form edge having a first Z-form edge profile substantially in accordance with X and Y coordinate values in a Cartesian coordinate system at points 69-82, as set forth in Table I, where X and Y are distances in inches from an origin and, when points 69-82 are connected by smooth, continuing arcs or lines, the points define the first Z-form edge profile.
