Title: Innovations by James E Fisher
Introduction
James E Fisher is a notable inventor based in Palm Beach Gardens, FL (US). He holds 2 patents that showcase his contributions to the field of engineering, particularly in turbine engine technology.
Latest Patents
One of his latest patents is the "Vane platform sealing and retention means." This invention presents an improved vane platform feather seal designed for use in turbine engines. The feather seal features a flat, thin design that is attached by adhesive to an L-shaped retainer plate, resulting in a combined thickness of 0.032 inches. This innovative seal is intended to replace the inner vane platform seals currently used in F-100 turbine engines, which have historically struggled to bend easily to conform to seal slots. The new seal offers enhanced platform sealing without compromising platform retention in the event of vane burn through.
Another significant patent by Fisher is the "Bushing securing apparatus." This invention addresses the issue of adjacent cylindrical bearings within a wall, preventing them from rotating and moving axially. The design incorporates a sheet metal tablock that engages a slot in the external surfaces of each bearing. A cap fits around each bearing, with a flange on each cap overlapping the tablock. The tab ends of the tablock are folded over the flange, effectively trapping the tablock in position.
