View the Complete Application at the US Patent & Trademark Office
A gas turbine, a gas turbine shroud, and a method for sealing a gas turbine shroud with a non-metallic seal are provided. The gas turbine shroud includes an inner shroud and an outer shroud. A non-metallic seal is located between the inner shroud and the outer shroud while a shroud retainer clip applies a compression force upon the inner shroud and the outer shroud. The compression force compresses the non-metallic seal to fill a gap space between the inner shroud and the outer shroud to control fluid flow between a flow path and a non-flow path.
