    Abstract: An assembly is provided for an aircraft. This aircraft assembly includes a powerplant. The powerplant includes a gas turbine engine, an exhaust nozzle and a flowpath extending from the gas turbine engine to the exhaust nozzle. The exhaust nozzle is movable between a first position and a second position. The exhaust nozzle is configured to exhaust combustion products, received through the flowpath from the gas turbine engine, when the exhaust nozzle is in the first position. The exhaust nozzle is configured to block flow of the combustion products through the flowpath when the exhaust nozzle is in the second position.

    Abstract: A first cascade segment of a thrust reverser system has a first cascade segment flow area and is associated with a first lateral sector. A second cascade segment has a second cascade segment flow area and is associated with a second lateral sector. The second cascade segment flow area may be at least 1.2 times the first cascade segment flow area. The first lateral sector has a first leakage flow area and a first total flow area that is equal to a sum of at least the first cascade segment flow area and the first leakage flow area. The second lateral sector has a second leakage flow area and a second total flow area that is equal to a sum of at least the second cascade segment flow area and the second leakage flow area. The second total flow area may be within 10% of the first total flow area.

    Abstract: A variable area nozzle assembly includes a fixed structure surrounding an exhaust duct extending along a nozzle axis. The fixed structure defines an exhaust duct outlet of the exhaust duct. The fixed structure includes a first side beam and a second side beam. Each of the first side beam and the second side beam extend in a direction axially aft from the exhaust duct outlet. Each of an upper thrust reverser door and a lower thrust reverser door are pivotably mounted to the first side beam and the second side beam at a first axial position. An upper panel and a lower panel are pivotably mounted to the upper thrust reverser door and the lower thrust reverser door, respectively, at a second axial position located axially forward of the first axial position. The upper panel and the lower panel define a nozzle outlet cross-sectional area therebetween.

    Abstract: A nacelle having a fan casing, a cowl that movable between an advanced position and a retracted position that opens an opening between a bypass duct and the outside, deflectors secured to the mobile cowl, wherein, in the advanced position, they are around the fan casing and wherein, in the retracted position, they are across the opening, and a fan ramp with a mounting base and flaps that are able to rotate on the mounting base between a stowed position and a deployed position. For each flap, the fan ramp has a return element that urges the flap) into the deployed position, and the deflectors have a stop in contact with the flap when the mobile cowl passes from the retracted position to the advanced position. Thus, in the advanced position, the flaps are folded back and their bulk is reduced.
