Abstract
A retention system for a plurality of turbine buckets (16) located in respective mating slots (12) in a turbine rotor wheel (10) includes a plurality of first circumferentially-oriented retention slots (26) formed in outer peripheral portions of the turbine wheel; a plurality of second circumferentially-oriented retention slots (34) formed in wheel mounting portions of said buckets, the first and second circumferentially-oriented retention slots aligned to form an annular lockwire retention slot; and a lockwire (36) located within the annular lockwire retention slot. A first surface feature on one or both of the turbine rotor wheel and one or more of said plurality of turbine buckets is adapted to engage a second surface feature on the lockwire for preventing rotation of the lockwire beyond predetermined limits.
