A fan nacelle, a gas turbine engine cell assembly, and an aircraft are provided. The fan nacelle includes a fan duct skin arranged in a fan duct to direct airflow from the fan of a Turbofan engine toward a fan nozzle. An exterior skin of the fan nacelle directs air flow around an exterior of the engine. The fan duct skin and the exterior skin terminate at a trailing edge, and a trailing edge portion of the exterior skin is one of parallel to and diverging from a trailing edge portion of the fan duct skin in an aft direction. In certain aspects, the trailing edge portion of the exterior skin is actuatable or inflatable to selectively divert from the trailing edge portion of the fan duct skin.

A nacelle for a dual-flow turbojet engine comprises a structure, a fixed cowl, a cowl translationally mobile on the structure, a window open between a secondary jet and the outside of the nacelle, and delimited by the fixed and mobile cowls, an outer thrust-reversing door rotationally mobile and a driving mechanism. The driving mechanism comprises a single power cylinder arranged at the level of a median plane and having a first end mounted articulated on the structure, a shaft with the second end of the power cylinder mounted articulated on the shaft, a first yoke joint secured to the outer thrust-reversing door and free to rotate on the shaft, and a second yoke joint secured to the mobile cowl, and where each of the two flanks of the second yoke joint has a groove in each of which the shaft is mounted to slide parallel to the median plane.

An inner fixed structure (IFS) seal arrangement may comprise an IFS comprising an inner skin, and outer skin, and a cellular core located between the inner skin and the outer skin, an IFS seal, a seal retainer configured to retain the IFS seal, and a cooling flow channel disposed between the outer skin and the seal retainer.

A method for gathering flight load data for a gas turbine engine includes providing a plurality of blocker doors rotatably mounted to a translating sleeve and a plurality of blocker door islands, each blocker door island disposed between circumferentially adjacent blocker doors of the plurality of blocker doors and mounted to at least one mounting point of the translating sleeve, wherein a blocker door island of the plurality of blocker door islands is a data acquisition unit; and connecting the data acquisition unit to at least one sensor in communication with the translating sleeve.

A thrust reverser is disclosed. The thrust reverser includes a frame, a first reverser door pivotally mounted to the frame, a second reverser door pivotally mounted to the frame and a hybrid exhaust duct. A first trailing edge of the first reverser door forms a portion of an exit plane of the thrust reverser and a second trailing edge of the second reverser door merges into the hybrid exhaust duct.
