Abstract
A retention system for a plurality of turbine buckets located in respective mating slots in a turbine rotor wheel includes a plurality of first retention slots formed in outer peripheral portions of the turbine wheel, and a plurality of second retention slots formed in wheel mounting portions of the buckets. The first and second retention slots are aligned to form an annular retention slot extending about a peripheral portion of the rotor wheel. A lockwire is located within the annular retention slot, the lockwire having engaged free ends. A plurality of axially-oriented retaining pins are fixed in the rotor wheel to hold the lockwire in the annular retention slot, and various techniques are employed for at least limiting or substantially preventing circumferential rotation of the lockwire within the annular slot.
