ABSTRACT:
An improved vane platform feather seal is disclosed for use in turbine engines. This feather seal contains a flat, thin feather seal, which is attached by adhesive to ease assembly to an L-shaped retainer plate to result in a combined thickness of 0.032 inches. This new seal may be used to replace the inner vane platform seals which are currently used in F-100 turbine engines, which have a history of not bending easily to conform to seal slots. The new seal provides improved platform sealing without loss of platform retention in the event of vane burn through.
