    Abstract: A method for a turbine blade assembly for a rotor groove is disclosed. A dovetail of the turbine blade includes a mounting arm and an end surface facing radially inward relative to the rotor axis. An extension insert includes a first end configured to contact the end surface of the dovetail and a second end. At least one positioning leg extends radially inward relative to the axis from the second end of the insert. The dovetail and the extension insert are configured to be positioned in the rotor groove to mount the turbine blade to the rotor. The mounting arm engages a radially inward facing rotor hook of the rotor groove and positioning leg(s) engage one of a radially outward facing surface of the rotor groove and a planar plate shim between the positioning leg(s) and the radially outward facing surface of the rotor groove.

    Abstract: 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.
