An assembly is provided for an aircraft propulsion system. This assembly includes a cowl door movable between a closed position and an open position. The cowl door includes a structural panel and a mount. The structural panel includes an inner skin, an outer skin and a cellular core. The cellular core is connected to and arranged between the inner skin and the outer skin. The mount includes a base and a coupler. The base is connected to and arranged between the inner skin and the outer skin. The coupler projects out from the base.

Structural panel with integrated coupler

A seal arrangement includes a first outer skin and a second outer skin disposed about an axial centerline. The second outer skin is adjacent the first outer skin and includes at least one door. A bulkhead extends substantially radially at least a portion of a distance between the axial centerline and one of the first outer skin and the second outer skin. A first outer frame includes a first portion, a second portion, and a third portion. The first portion of the first outer frame is mounted to the bulkhead. A seal is mounted to one of the at least one door and the second portion. The at least one door is rotatable between a first position and a second position. In the second position the seal contacts the at least one door and the second portion. The third portion is configured to limit a compression of the seal.

Seal arrangement

A fluid conduit assembly is provided that includes a first conduit coupler, a second conduit coupler and a lock. The second conduit coupler is mated with the first conduit coupler at a threaded interface. The lock is configured to rotationally fix the first conduit coupler with the second conduit coupler. The lock includes a flange, a clip and a fastener. The flange is arranged with the first conduit coupler. The flange is configured with a plurality of flange apertures arranged circumferentially about an axis of the first conduit coupler. The clip is arranged with the second conduit coupler. The clip is configured with a clip aperture. The fastener is mated with the clip aperture and any one of the plurality of flange apertures.

Conduit fluid coupling with anti-rotation lock

Acoustically treated components and methods of acoustic treating are provided. The acoustically treated components include a structural fitting having a first surface and a second surface, wherein the first surface defines a flow path and includes a plurality of perforations passing through the structural fitting from the first surface to the second surface, at least one non-structural acoustic treatment member installed on the second surface, a first end of the at least one non-structural acoustic treatment member attached to the second surface such that a cellular structure of the at least one non-structural acoustic treatment member aligns with the plurality of perforations, and a cover attached on a second end of the at least one non-structural acoustic treatment member such that an acoustic chamber is defined between the cover and the cellular structure and open to the flow path.
