Title: Self-supported, self-locating seal for turbine engines

Abstract: A self-supporting, self-locating seal having a central portion and a pair of end segments so designed as to fit within the mid span joint formed between adjacent turbine engine blades. Because of the design of the seal, the seal is held securely in position simply by its geometry and the centrifugal forces applied thereto during turbine engine operation.
