Abstract:
A turbofan engine nacelle has a downstream section which includes at least one front frame. The front frame is attached to a stationary portion of the nacelle, and the downstream section is provided with at least one rail or slide which extends in a longitudinal direction of the nacelle and is capable of engaging with at least one corresponding slide or rail of an attachment pylon of the turbofan engine. The front frame is connected to the rail or slide of the downstream section by means of at least one swiveled connecting rod.
Abstract:
A device for handling a load provided with a thread includes a screw assembly equipped with a gripper and capable of connecting to the load, a first screwing indicator secured to the screw assembly, a second screwing indicator movable in translation relative to the first screwing indicator, and a spring. In particular, the spring is inserted between the first screwing indicator and the second screwing indicator and has an effect of returning the second screwing indicator such that the second screwing indicator abuts against the load, so that a coincidence between the first and second screwing indicator indicates a sufficient screwing of the device onto the load.
Abstract:
The present disclosure provides an aircraft element including a leading edge section and a trailing edge section, and the leading edge section includes an anti-frost treatment device. This aircraft element is remarkable in that the trailing edge section includes a superhydrophobic surface.
Abstract:
A weaving loom includes a system for inserting weft threads in a plurality of layers and a system for inserting and sequencing warp threads in such a way as to produce a multilayer fabric having a defined weave. It includes at least two feed systems of which the speed and traction force are controlled such that, at least locally, one portion of the layers of fabric is driven by the feed mechanism of same at a different speed to at least one other portion of the layers of multilayer fabric so as to produce at least one aperture on the multilayer fabric.
Abstract:
The present disclosure provides a method for manufacturing a sound attenuation panel having a first cellular core structure and a second cellular core structure joined in a junction area (J). The method includes: a) a joining edge of the first cellular core structure is joined to a corresponding joining edge of the second cellular core structure, thereby forming the junction area; b) the first cellular core structure and the second cellular core structure are placed between an inner skin and an outer skin of the panel.In particular, the method further has a step prior to step a), in which one junction reinforcement is inserted between the joining edge of the first cellular core structure and the corresponding joining edge of the second cellular core structure in the junction area.
Abstract:
An air intake structure for a turbojet engine nacelle includes a substantially annular main structure having an internal wall, an external wall and an air intake lip structure connecting the external and internal walls upstream. The air intake structure also includes a first acoustic attenuation structure which has a holed acoustic skin, a cellular core and a solid rear skin with which the internal wall is equipped, and a second acoustic attenuation structure having a similar architecture fitted to a part of the air intake lip substantially near a junction with the internal wall. The rear skin of the first acoustic attenuation structure is aligned with the rear skin of the second acoustic attenuation structure, both of rear skins being structural.
Abstract:
A cascade-type thrust reverser for an aircraft turbojet engine includes a front frame, a sliding cowl between a direct jet position and a reverse jet position, a plurality of actuating cylinders interposed between this front frame and this sliding cowl, and a plurality of cascades pivotally mounted on the front frame between the direct and reverse jet positions. In the direct jet position, the cascades are substantially parallel to the axis (A) of the thrust reverser, and in the reverse jet position, the cascades are inclined relative to the axis (A) of the thrust reverser. In particular, the cascade-type thrust reverser includes a single radial layer of cascades.
Abstract:
The present disclosure provides a thrust reverser device for a turbojet engine nacelle which includes at least two cowls each mounted with the ability to move translationally with respect to a fixed structure between an upstream closed position and a downstream open position. In the upstream position, the two cowls provide aerodynamic continuity of the nacelle, and in the downstream open position, they open a passage in the nacelle. The thrust reverser device further includes at least one synchronization cable extended between the two mobile cowls so as to have a first end attached to an upstream point of one of the two cowls, and a second end attached to a downstream point of the another cowl. In particular, the upstream and downstream attachment points are determined relative to a fixed central zone where the cable passes between the two cowls.
Abstract:
A unit for an aircraft thruster is provided that includes a first ferrule configured to be attached to a second ferrule and a first connection flange configured to be secured to a second corresponding connection flange secured to the second ferrule. The connection flange includes a portion forming a plane extending along a radial direction with respect to the first ferrule. A link between the first ferrule and the corresponding connection flange is offset to a distance from said plane corresponding to a length for damping a shear-generating flexural moment, generated by fluxes of forces passing through the first ferrule.
