Zusammenfassung:	A damper pin 100 for damping adjacent turbine blades 28 coupled to a rotor shaft 22 includes a first end portion 102 that is axially aligned with and axially spaced from a second end portion 104 and a retention pin 116 that is coaxially aligned with and disposed between the first end portion 102 and the second end portion 104. The retention pin 116 couples the first end portion 102 to the second end portion 104. The damper pin 100 further includes a plurality of rings 122 coaxially aligned with and disposed along the retention pin 116 between the first end portion 102 and the second end portion 104. The first end portion 102, the second end portion 104 and the plurality of rings 122 define a generally arcuate outer surface 124 of the damper pin (100) that is configured to contact with a groove defined between the adjacent turbine blades 28.
