PROBLEM TO BE SOLVED: To promote a damping system (100) for a turbine rotor blade (105). SOLUTION: The damping system (100) includes a damper pocket (200) and a damper pin (230). The damper pocket (200) is provided with a variable depth in the tangential direction, and the damper pin (230) is placed in the interior of the damper pocket (200). The rotor blade (105) has a convex surface (150), and the damper pocket (200) may be placed on the convex surface (150). The rotor blade (105) has a concave surface (155), and the rotor blade (105) may have an undercut (180) on the concave surface (155). COPYRIGHT: (C)2008,JPO&INPIT
