ABSTRACT:
A damper for damping the vibration of blades in a turbine rotor including a plate having at least one bumper extending outwardly from one side of the plate to be positioned in recesses on the underside of the platforms on adjacent blades for locating the bumper circumferentially and with a tab extending inwardly from the plate on the side opposite to the bumper to hold the damper in radial position. A wear strip extending upwardly from the plate near its periphery serves as a seal to minimize gas leakage past the damper.
