  • Method and apparatus to facilitate increasing turbine rotor efficiency
    Patent number: 8128371
    Abstract: A method facilitates assembling a turbine. The method includes coupling buckets to a turbine wheel. The method also includes coupling a first end of a cover plate to the turbine wheel such that at least one projection extending from the turbine wheel retains the cover plate in position relative to the turbine wheel and inserting a fastening mechanism through an opening defined in the turbine wheel to secure the cover plate against the turbine wheel. The cover plate facilitates reducing dovetail leakage across the buckets coupled to the turbine wheel.
