| description | A turbine including a plurality of buckets (124,126,128,130) each including a dovetail (208) is provided. The turbine includes a turbine wheel (116,118,120,122) including a plurality of retaining slots (210) defined therein, each of the plurality of retaining slots is sized to receive each of the plurality of bucket dovetails therein, the turbine wheel further including at least one projection extending outward from the turbine wheel. The turbine further includes at least one cover plate (200,501) coupled to the turbine wheel such that the at least one projection retains the cover plate in position against the turbine wheel, and at least one fastening mechanism (220) inserted through an opening defined in the turbine wheel to secure the cover plate to the turbine wheel such that the cover plate facilitates reducing dovetail leakage across the plurality of buckets adjacent to the cover plate. |
