    Abstract: A pivoting connection device connects at least two components and comprises a guide ring, positioned in an orifice of a first branch of a clevis, which guide ring has a tubular body together with a flange pressing against the interior face of the first branch, a cylindrical shaft connecting the clevis and an arm, having a first end stop, configured to prevent translational movement of the cylindrical shaft in a first sense and a second end stop configured to prevent translational movement of the cylindrical shaft in a second sense, the opposite to the first sense, an immobilizing system configured to immobilize the cylindrical shaft in terms of rotation with respect to the guide ring, the guide ring comprising a first longitudinal groove or slot configured to allow the first end stop to pass.

    Abstract: An assembly having a pylon with an upper spar and four lateral scoops, a wing with a skin, longitudinal spars and fittings, and, for each lateral scoop, two fastening assemblies, wherein the skin and the fitting each have a first bore and wherein the upper spar and the lateral scoop each have a second bore, wherein each fastening assembly has a screw passing through the first and the second bores, a nut, two eccentric rings, threaded onto one another and onto the screw, and a system for stopping the eccentric rings rotating. The assembly makes it possible to dispense with the use of the spigots while also ensuring the reaction of the shear forces contained in the XY plane by the bolts on account of the reduced tolerances between the various bores, the external and internal surfaces of the eccentric rings and the plain zones of the screws.

    Abstract: An aircraft comprising a fastening element and an engine pylon with two rear covers. Each cover includes a movable lower cover mounted articulated on a rear portion in which in the closed position, the two movable lower covers are moved together and in which in the open position, they are tilted and moved apart from each other. For each movable lower cover, a hinge system, and at least one locking system locks the two movable lower covers together in the closed position and locks each movable lower cover to the fastening element in the open position. The presence of the movable lower covers provides, inter alia, easy access to the inside of the engine pylon, and the locking system locks the movable lower covers.

    Abstract: A bolt comprising a threaded shaft having at least one helical thread and at least one longitudinal groove, a nut having a tapped hole configured to be screwed onto the threaded shaft, and at least one diagonal slot which includes a first opening end and a second non-opening end. The diagonal slot is inclined from the first end towards the second end in the same direction as the helical thread of the threaded shaft. An anti-rotation device is configured to rotationally immobilize the nut with respect to the threaded shaft and comprises a ring which surrounds at least the threaded shaft and which has at least one first toe configured to be housed in the longitudinal groove of the threaded shaft and in the diagonal slot of the nut, in operation.

    Abstract: An assembly of a pylon and of an engine with a rear engine attachment having two fittings, wherein each one has a shoe fastened to a lower spar of the pylon, two transverse arms, one front and one rear, which are as one with the shoe and offset such that the front transverse arm, respectively rear transverse arm, of one fitting bears in planar fashion against the front transverse arm, respectively rear transverse arm, of the other fitting, wherein each transverse arm is pierced with a bore, wherein the two front transverse arms and the two rear transverse arms are spaced apart parallel to the longitudinal direction and thus form a female clevis, and wherein the assembly also has a lower rod mounted articulated in the female clevis and on the engine. With such an assembly, the number of components is reduced.
