Abstract : The patent relates to a non-abradable turbine seal for use between the blade member and surrounding shroud of the turbine engine. The seal may take on a variety of configurations, any one of which constructed to allow deformation thereof by the blade member, either because of rotor growth or shroud eccentricities. The seals are made of oxidation resistant compressible or crushable materials in the form of thin metallic foil, pads, ceramic hollow spheres or thin walled tubing.
