  • Wall construction for gaspath traversing component
    Patent number: 10711625
    Abstract: A gaspath traversing component of a gas turbine engine comprises a wall having an outer edge surface and a thickness relative to the gaspath, the wall having a plurality of layers of composite materials forming the thickness. A wear indication layer is embedded within the plurality of layers of composite material, the wear indication layer being visually contrasting with the composite material. The wear indication layer is positioned interiorly of at least one layer of said plurality of layers of composite material relative to the outer edge surface. A method for attending to a gas traversing component of a gas turbine engine is also provided.

  • Inner bypass duct
    Patent number: 9919500
    Abstract: An inner bypass duct of a gas turbine engine includes a plurality of non-structural front panels arranged circumferentially. Each front panel has an outer surface and an inner surface. The inner surface is at least partially covered by a composite structure. The composite structure includes a fireproof layer and an acoustic layer disposed between the fireproof layer and the inner surface. A non-structural panel for an inner bypass duct and a method of forming such panel are also presented.
