  • Patent number: 10605198
    Abstract: A thrust reverser of a nacelle is orientated at least in-part about a fan case of a turbofan engine. The thrust reverser includes an outer fixed structure assembly and a radial spacer. The outer fixed structure assembly circumferentially extends about a centerline and is spaced, at least in part, radially outward from the fan case. The radial spacer is engaged to the outer fixed structure assembly and is in sliding contact with the fan case.

  • Patent number: 10514004
    Abstract: A cascade assembly of a nacelle for a turbofan engine includes a one-piece cascade fixed to a translating sleeve constructed and arranged to move between forward and aft positions along a centerline. A hook device of the cascade assembly includes a first catch fixed to a stationary structure and a second catch fixed to the one-piece cascade. The first catch is adapted to mate with the second catch for translating load when the cascade assembly is in a deployed state and the translating sleeve is in the aft position.

  • Patent number: 10428764
    Abstract: A cascade assembly of a nacelle for a turbofan engine includes a cascade concentrically disposed about an centerline, and a translating sleeve constructed and arranged to move between a forward position and an aft position along the centerline. A deflection limiter of the cascade assembly includes a first surface facing at least in-part in a radial direction and a second surface facing at least in-part in an opposite radial direction. The first surface is carried by one of the cascade and the translating sleeve and the second surface is carried by the other of the cascade and the translating sleeve. The first and second surfaces oppose one-another for limiting deflection when the translating sleeve is in the aft position and are spaced axially apart when the translating sleeve is in the forward position.

  • Patent number: 10160552
    Abstract: A nacelle for a turbofan engine includes a fan case, an inner barrel and a nose lip generally concentrically disposed about an axis. The inner barrel projects forward from and is engaged to the fan case at a first split line. The nose lip is engaged to the inner barrel at a second split line, and extends substantially radially outward directly from the second split line, then substantially axially rearward to the fan cowl as one unitary piece.

  • Patent number: 9086034
    Abstract: An aircraft engine thrust reverser cascade assembly includes a plurality of circumferentially spaced cascade segments, each cascade segment including a plurality of spaced vanes, including an aft-most vane, and rails defining a series of cells or air passages therebetween. The cascade assembly also includes an aft cascade ring removably attached to the aft ends of the cascade segments. A flow deflection shelf is mounted to each of the cascade segments and includes a deflector portion that at least partially extends forward of a group of cells of the cascade segments along which the flow deflection shelf is mounted. The deflector portion is configured to at least partially redirect at least a portion of a volume of air forwardly as the air outwardly passes through the group of cells of the cascade segments.
