Abstract:
A bucket for a turbomachine rotor wheel includes an airfoil portion, a shank portion and a dovetail mounting portion, the shank portion including opposite sides, one of the sides formed with a substantially axially-oriented groove extending between forward and aft ends of the shank portion. The other one of the opposite sides is formed with at least one substantially radially-oriented groove. The substantially axially-oriented groove is adapted to receive an elongated damper pin, and the at least one substantially radially-oriented groove is adapted to receive an elongated radial seal pin.
