Abstract: A method and system for sealing a gap between a bucket dovetail and a rotor is provided. The dovetail seal includes a first end portion extending from a first extent of the first end portion a predetermined distance along a length of the dovetail seal, a second end portion extending from a first extent of the second end portion a predetermined distance along a length of the dovetail seal towards the first end portion, and a body extending between the first and second end portions. The body includes a U-shaped bend complementary to a sealing groove in a dovetail of a turbine blade. The first end portion includes a converging flared cross-section from the first extent of the first end portion toward the second end portion and the second end portion includes a converging flared cross-section from the first extent of the second end portion toward the first end portion.
