Abstract
A turbine blade assembly for a turbine assembly includes a turbine blade having a turbine blade damper cavity formed therein and a plurality of pins positioned within the turbine blade damper cavity. The pins are maintained in the damper cavity during operation of the turbine blade assembly. They reduce vibration of the turbine blade assembly during operation by dissipating energy by friction between adjacent pins and between the pins and the internal surface of the blade that defines the damper cavity.
