Abstract: A dovetail attachment seal for a turbomachine includes an outer seal member having a first end that extends to a second end through an intermediate portion, and at least one articulating element encapsulated, at least in part, by the outer seal member at one of the first and second ends. The at least one articulating element is slidingly disposed within the outer seal member.

Abstract: A method for modifying an airfoil shroud located at a tip of an airfoil is provided. A locating step locates a reference location in a first end edge. The reference location includes a portion of a fillet. A seal rail extends circumferentially along a radially outer surface of the airfoil shroud. The fillet extends along the radially outer surface and is positioned directly adjacent to the seal rail. A forming step forms a compound relief cut in the fillet without performing a weld process on the airfoil shroud to remove the reference location. The compound relief cut has a first cut having a first radius extending from the seal rail towards the first end edge, and a second cut having a second radius extending from an end of the first cut to the first end edge. Modifying the airfoil shroud is complete following forming the compound relief cut.
