Abstract
A vibration dampening system is provided for a turbine nozzle or blade. A body opening extends through the turbine nozzle or blade, e.g., through the airfoil among potentially other parts of the nozzle or blade. A vibration dampening system includes a plurality of stacked damper pins within the body opening. Each damper pin includes an outer body having defined therein an inner opening and a plurality of side openings extending from the inner opening through an outer surface of the outer body; and an inner body that is nested and movable within the inner opening of the outer body. The inner body includes a first portion including a plurality of arms, each arm extending through a respective side opening of the outer body to frictionally engage the body opening. The end surfaces of the damper pins and the two bodies frictionally engage to dampen vibration.
