. Dkt. 13-DV-9858 ABSTRACT OF THE DISCLOSURE A vibration damper is disposed between each adjacent pair of turbine buckets of a gas turbine engine to act in a V-shaped groove defined by bevelled platform surfaces of the adjacent buckets. The damper is wedge-shaped in cross section and is provided with a pad on one side and two pads on another side. When the damper is propelled into the groove by centrifugal force, it assumes a consistent equilibrium position with the raised surface of the one pad slidingly engaging one of the platform bevelled surfaces and the raised surfaces of the other two pads slidingly engaging the other bevelled platform surface to dissipate vibrational energy in the buckets.
