An improved thrust reverser for an aircraft propulsion assembly includes redirection of the air flow for performing the thrust reversal by one or more closure membranes, i.e. by thin and flexible structures deployed across the propulsion assembly. The improved thrust reverser includes at least one closure membrane arranged to deflect at least one portion of the air flow in the direction of the evacuation structure when the thrust reverser is in the reverse jet position and an intermediate structure movable in rotation relative to the fixed structure.

A thrust reverser includes two thrust reverser elements movable between a retracted position in which the thrust reverser is inactive and a deployed position in which the thrust reverser is active, a cylinder for deploying the thrust reverser elements, and a single-acting cylinder for retracting the thrust reverser elements.

An aircraft nacelle arrangement includes a compression rod disposed between a first nacelle half and a second nacelle half, wherein the first nacelle half and the second nacelle half are rotatable about a hinge between a closed position and an open position, a compression rod disposed between the first nacelle half and the second nacelle half, and a mounting bracket coupled to an exhaust nozzle flange of the aircraft engine, wherein the compression rod extends through the mounting bracket.

A hybrid mandrel for forming a composite part may comprise a core and a sleeve located around the core. The core may include a rigid material. The sleeve may comprise an elastomeric material. The part may be formed by locating the hybrid mandrel in an injection mold, depositing a molten resin around the hybrid mandrel, curing the molten resin; and removing the hybrid mandrel.

A bell-mouth scoop assembly includes an actuator comprising a plurality of hinge members configured to rotate in unison about a respective hinge axis of rotation from a first stowed position to a second deployed position and at least one linkage arm extending outwardly from at least one of the plurality of hinge members. The bell-mouth scoop assembly further comprises a bell-mouth panel comprising a panel longitudinal centerline and pivotably coupled to each linkage arm, in the first stowed position the bell-mouth panel (configured to conform to an outer surface of the with the panel longitudinal centerline aligned about a circumference of the flow discharge nozzle, in the second deployed position the bell-mouth panel configured to extend away from the outer surface of the flow discharge nozzle with the longitudinal centerline aligned parallelly with the nozzle centerline.

A cascade array vane is provided that includes a vane, a first longitudinal portion, a second longitudinal portion, and at least one coupling feature. The vane includes an airfoil portion extending between a first end and a second end. The first longitudinal portion is disposed at the first end of the vane extending outwardly from the vane. The second longitudinal portion is disposed at the second end of the vane extending outwardly from the vane. The at least one coupling feature is incorporated with at least one of the first longitudinal portion or the second longitudinal portion.

A pressure measurement tool secured to a rod arranged across a duct of an engine of an aircraft. A sheath includes two walls which bound a space receiving the rod, the space communicating with the outside by an opening extending over the length of the sheath, the sheath having a bay extending over the length of the sheath and cavities distributed over the sheath. For each cavity, an air inlet including a passage opens at one end into the cavity another end into the duct. A printed circuit board runs along the bay. For each passage, a pressure sensor in the corresponding cavity faces the passage and is on the printed circuit board. A unit is provided for processing and/or recording the data transmitted by the pressure sensors. It is thus easy to install and makes it possible to take a large number of measurements in the secondary duct.
