Abstract: A rotor assembly includes a rotor having a dovetail slot. The dovetail slot includes a plurality of recesses and a first radially innermost surface. A rotor blade includes an airfoil that extends radially outward from a platform and a dovetail that extends radially inward from the platform. The dovetail includes a plurality of projections extending in opposite directions that are received by the plurality of recesses of the dovetail slot. The dovetail further includes a leading edge surface, a trailing edge surface, and a second radially innermost surface. The second radially innermost surface defines a groove from the leading edge surface to the trailing edge surface. The shim is positioned within the groove and between the first radially innermost surface of the dovetail slot and the second radially innermost surface of the dovetail. The shim extends at least partially radially along both of the leading edge surface and the trailing edge surface to secure the rotor blade within the dovetail slot during various operating conditions of the turbomachine.

Abstract: A turbine blade has a first end, and an opposing second end. A base includes a dovetail for complementing a corresponding dovetail slot in a rotor. The dovetail has a body and a plurality of projections extend from the body in opposing directions. A tapered groove extends through the body from the first end to the second end, and 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. The tapered groove is open at a bottom surface of the body and is sized to engage a shim. The tapered groove includes a flat section near the first end or the second end, and the flat section has a constant depth.
