Zusammenfassung:	A turbine blade includes a blade having a first end, and a second end opposite the first end. A tip is located at an outer radial portion of the blade. A blade dovetail complements a corresponding dovetail slot in a turbine rotor. The dovetail has a body, and a plurality of projections extending from the body in opposing directions for complementing a plurality of recesses in the corresponding dovetail slot. A tapered groove extends through the body from the first end to the second end. The tapered groove has a tapered profile such that a first depth of the tapered groove near the first end is greater than a second depth of the tapered groove near the second end. The tapered profile gradually transitions from the first depth to the second depth, so that the tapered groove is open at a bottom surface and sized to engage a shim.
