Abstract: A fluidic connector to connect two ducts of a system such as an air conditioning system. The connector includes at least one elastic material, and includes a duct surrounded by an adjustable clamping collar which, when tightened, serves to deform it to reduce the internal space of the duct. The clamping of the collar makes it possible to easily and quickly regulate the rate of flow in the ducts.

Abstract: A device for fitting two components together by a clevis is improved by a seal including a deformable ring subjected to axial compression between one of the cheeks and a mobile washer which is brought closer to the cheek when a bolt passing through the clevis is tightened. This axial compression causes the rod to be clamped by the seal, eliminating all play and giving the assembly good cohesion while at the same time eliminating the transmission of vibration and noise.

Abstract: A flexible corner fitting configured to contribute to a connection between at least three walls of at least one aircraft box structure, and to make them leaktight with respect to liquids. The corner fitting has at least three fixing plates and at least three edge corners made of flexible material. Each of the at least three fixing plates is connected to each of the other at least three fixing plates by one of the edge corners made of flexible material. The edge corners made of flexible material ensure adjustment of the corner fitting without machining or the addition of shims.

Abstract: A flexible pillar for a variable geometry flight control surface including upper skin and lower skins includes an elongate shape elastic element having an and at least a first end and a second end. The flexible pillar can be disposed between the upper skin and the lower skin so the elastic element can be fixed to the upper skin at the first end of the flexible pillar and fixed to the lower skin at the second end of the flexible pillar. The flexible pillar has a rigidity along the longitudinal axis of the flexible pillar that is greater than a rigidity of the flexible pillar in shear along a transverse axis of the flexible pillar, the flexible pillar making it possible to obtain a support having a longitudinal direction and able to transmit forces between its ends without, or with little, deformation longitudinally and to be easily deformed in a transverse direction.

Abstract: A storage tank for a cryogenic fluid including an inner tank that is configured to store the fluid and that is seated in an outer envelope, the inner tank and the outer envelope having a shared longitudinal axis, such that a thermal insulation volume surrounds the inner tank, and wherein the outer envelope surrounds the volume about the inner tank. The tank has at least one damping element made of a deformable material positioned between one end of the inner tank and the outer envelope to wedge the inner tank against the outer envelope. This enables a reliable sliding mechanical link to be formed between at least one end of the inner tank and the outer envelope of the tank, thereby increasing resistance to wear and facilitating assembly of the tank.

Abstract: To improve the seal between a wing and a ventral fairing of an aircraft, an assembly includes an air seal system arranged in an opening, between the ventral fairing and the wing. The seal system includes a sealing blade, a first end of which presses against the wing, and a connecting device, on the ventral fairing, for a second blade end that is opposite the first end. The connecting device includes at least one first connecting layer, of which a first connecting face is secured to a first surface of the sealing blade, and of which a second face, opposite the first face, is secured to the ventral fairing, the first connecting layer being made of a material including an elastomer.

Abstract: An assembly having a chassis, two supports with a plate and a guide, a nesting system with a bore, a reservoir containing an extinguishing fluid and with two fastening tabs, two bearing tabs and a peg, and a fastener. The reservoir is able to move in translation between a premounting position in which each fastening and bearing tab rests on a plate and each guide guides the fastening and bearing tabs to align the peg and the bore, and a mounting position in which each fastening tab rests on the plate, the peg is introduced into the bore, the bearing tabs no longer rest on the plates and the fastener fastens each fastening tab to the plate. Such an assembly allows the reservoir to be withdrawn and put in place quickly and easily.

Abstract: A propulsion unit, and an aircraft, with a propeller and electric motor, including at least one intermediate element interposed between the electric motor and the propeller and configured to transmit at least thrust loads generated by the propeller, a primary structure supporting the propulsion unit, at least one interface having: a first load path, configured to transmit loads perpendicular to the axis of rotation of the propeller, linking the at least one intermediate element to a support linked rigidly to or incorporated in the primary structure, a second load path, configured to transmit loads that are parallel to the axis of rotation of the propeller, linking the at least one intermediate element to a support linked rigidly to or incorporated in the primary structure.

Abstract: A connection assembly between two structures, the assembly including an assembly of two eccentric rings, one of which, the external ring, is fitted on the other, being formed as an insert, a bore of the internal ring being configured to fix to one of the structures using a fixing element, and the external ring being accommodated and retained in a through-opening of the other structure, at least one of the eccentric rings being made from a deformable material in order to at least compensate for a play when it is compressed by two retention and compression elements during assembly. Advantageously, it is thus possible to benefit from a mechanical play which facilitates the assembly and to eliminate this play during a tightening operation of the fixing element in order to improve a transfer of loads between the two structures.

Abstract: A connecting assembly for connecting two structures of an aircraft, the connecting assembly including a central element featuring a through-hole, preferably a bore, configured to make a connection with one of the two structures by virtue of a fastener element including a shank inserted into the through-hole. The connecting assembly further includes a plurality of shock-absorbing elements made from a deformable material. Each of the shock-absorbing elements are, on the one hand, secured to the central element and, on the other hand, configured to bear against a surface of the other of the two structures. An aircraft part includes such a connecting assembly.
