  • Patent number: 10837302
    Abstract: A blade track assembly is disclosed having a variety of features. The assembly can have annular or segmented components, or a combination of the two. In one form the assembly includes blade tracks having a forward and aft edge that can be received in an opening of respective hangers. The hangers can include anti-movement features to discourage movement of a blade track. A rib can extend between hangers and in one form can be used as part of a seal assembly. Clips can be used to secure the blade track in openings of the respective hangers, as well as to discourage movement of the blade track.
    Type: Grant

  • Patent number: 9951640
    Abstract: A structure providing compliance and sealing between ceramic or ceramic composite (CMC) part and a metallic part has an interface component for centering the CMC part in the metallic part, thus reducing thermal stress motion of the CMC component. In gas turbine engine applications, the structure comprises a CMC blade track inserted in a clip placed within a metallic hanger. The clip provides for radial compliance and secures controlled leakage of cooling air required to ensure that acceptable temperatures are maintained for the metallic structures. A washer is positioned adjacent to the clip provide for axial orientation of the blade track.

  • Patent number: 4538387
    Abstract: A water drainage and thermal insulating material for subterranean walls consisting of a panel adapted to be applied to the exterior surface of a wall prior to applying earth or other backfill material to its outer surface. The panel consists of a relatively thick slab of thermal insulating material, both surfaces thereof being grooved in a diamond pattern to provide water flow passages, the slab being completely wrapped in a filter cloth fabric with a layer of loosely compacted fibrous material secured to the surface thereof confronting the slab. All of the materials are substantially impervious to ground moisture.
