Abstract
A seal for a dovetail joint in a turbomachine is provided. The seal includes an arcuate member having a first end, a middle portion and a second end. The seal also includes sealing means, which include at least one sealing member. The sealing member can comprise a first sealing member connected to the first end and/or a second sealing member connected to the second end. The dovetail joint is the interface between a bucket dovetail and a rotor dovetail groove, and the seal reduces the amount of cooling flow leakage from the dovetail joint.
