  • Patent number: 11022072
    Abstract: A divergent flap seal includes a flap seal body with a spine, the flap seal body manufactured of a non-metallic material. A mount is engaged with the spine at the dovetail interface and a resilient member at the dovetail interface.
    Type: Grant
    Filed: February 23, 2017
    Date of Patent: June 1, 2021
    Assignee: Raytheon Technologies Corporation
    Inventors: Truc Luong, Keegan M. Martin
  • Patent number: 10260427
    Abstract: A gas turbine engine includes a first duct, a second duct, and a bladder. The bladder is disposed in the first duct and communicates with the second duct. A first gas flow is capable of passing through the first duct and a second gas flow is capable of passing through the second duct. The bladder is adapted to receive a bleed gas flow from the second duct and inflate within the first duct, thereby decreasing an area in the first duct through which the first gas flow is capable of traveling.
    Type: Grant

  • Patent number: 9133768
    Abstract: A hanger for a gas turbine exhaust system includes an exhaust duct attachment structure associated with an exhaust duct and a liner attachment structure associated with a liner spaced radially inwardly of the exhaust duct. The exhaust duct attachment structure and the liner attachment structure cooperate to suspend the liner within the exhaust duct such that the exhaust duct and liner are movable relative to each other. At least one resilient member generates a resilient biasing force between the exhaust duct attachment structure and the liner attachment structure.

  • Patent number: 7845176
    Abstract: In one example, a gas turbine engine includes an exhaust nozzle. The exhaust nozzle includes a flap supported relative to a static structure by a strut. The flap includes a backbone providing a slot. A slider interconnects a strut end to the backbone. In one example, the slider includes a body that is slidingly received within the slot. A boss extends from the body and provides a first feature. The strut end includes a second feature that cooperates with the first feature to prevent relative rotation between the slider and a portion of the strut end.
