Abstract: An acoustic liner can include a support layer with a set of partitioned cavities defining a set of cells with open faces, a first facing sheet operably coupled to the support layer such that the first facing sheet overlies and closes the open faces, and a set of internal separator structures within at least some of the set of partitioned cavities.

Abstract: An acoustic liner may include an acoustic core having an array of resonant cells, and an acoustic screen disposed across the array of resonant cells. The resonant cells include a plurality of cell walls and a resonant space defined by the plurality of cell walls. The acoustic core may include a folded acoustic core. Additionally, or in the alternative, at least some of the resonant cells may include an oblique polyhedral cellular structure and/or a multitude of sound-attenuating protuberances. The acoustic screen may include a reticulate membrane and a support lattice.

Abstract: A thrust reverser assembly for high-bypass turbofan engine. The thrust reverser assembly includes a translating cowl mounted to a nacelle of an engine. The thrust reverser assembly includes blocker doors axially guided adjacent first ends thereof by a fixed structure and pivotally and slidably connected along lengths thereof to an inner wall of the translating cowl so that translation of the translating cowl in the aft direction causes the blocker door to move from a stowed position to a deployed position. The thrust reverser assembly includes a stop disposed on the core engine or on the blocker door, receiving the load from the high pressure airflow, otherwise borne by an actuation system when deploying the translating cowl and blocker door.

Abstract: A gas turbine engine and thrust reverser assembly having a set of outer doors movable between a stowed position and a deployed position, where the set of outer doors extends outwards from the nacelle and a set of blocker doors movable between a stowed position and an deployed position, where the set of blocker door extends into an air flow conduit defined by the bypass duct to deflect air outwards.
