Turbine bucket tip shroud edge profile

The invention relates to a turbine blade tip shroud edge profile. The turbine blade comprises a blade airfoil (34) with a tip shroud (36). The tip shroud (36) comprises a leading edge (48) having two scalloped faces (52, 54) and a trailing edge (50) having a third scalloped face (56) defining leadin...

Zusammenfassung:	The invention relates to a turbine blade tip shroud edge profile. The turbine blade comprises a blade airfoil (34) with a tip shroud (36). The tip shroud (36) comprises a leading edge (48) having two scalloped faces (52, 54) and a trailing edge (50) having a third scalloped face (56) defining leading and trailing edge profiles substantially in accordance with Cartesian coordinate values of X and Y as points 1-41 set forth in Table I. The X and Y values are distances in inches which, when respective points are connected by smooth, continuing arcs define the leading and trailing edge tip shroudscalloped profiles. The tip shroud further also has a first and a second, upper and lower, Z form edge profiles (38, 40) substantially in accordance with Cartesian coordinate values of X and Y as points 42-59 and 60-77, respectively of Table II.
