Abstract: A propulsive assembly for aircraft comprising an engine, a nacelle arranged around the engine and a pylon supporting the engine, the nacelle including two engine cowls and reversing cowls, each cowl having an internal skin, characterized in that at least one of the cowls of the nacelle comprises at least one box arranged in a space situated between the internal skin of the cowl and the engine, the box delimiting a volume of inert material, the inert material being flame retardant foam. This box partially blocks a zone of the engine where a fire is likely to begin, which makes it possible to limit the volume of a fire zone of the engine, and thus reduce the quantity of extinguishing agent which is necessary to extinguish a fire in the zone of the engine concerned.

Abstract: The present invention concerns a fastener (110) for the temporary assembly of at least two previously drilled structures (112) comprising: a hollow body (122) comprising a bearing surface (40); elastic clips (24) which are movable relative to the body and which form a projection relative to the bearing surface; a spacer (26) around which the elastic clips are positioned; a connecting element (130), extending within the body and secured to the elastic clips (24); and an actuating element (132) linked to connecting element by a thread/tapping (67, 84). The connecting element is traversed by a lateral opening (70) axially extended between two closed ends (72, 74); and the fastener also comprises a transverse stop (28) secured to the spacer, the said stop being capable of sliding between the axial ends of the said lateral opening.

Abstract: The invention relates to a fastener (10) for the temporary assembly of structures (12, 13), comprising: a tubular body, extending between a first end and a second end comprising at least two longitudinal tabs (46); a hooking element, rotationally prevented and capable of sliding axially in the body, said fastening element comprising a tubular base and a plurality of elastic clips (62) connected to one end of said base, each clip comprising a hooking spur (74); a driving device for the fastening element; and a spreader (26) fixed relative to the body, the plurality of elastic clips being positioned around said spreader. The tubular base (60) comprises two longitudinal grooves in an outer surface; and the fastener is configured so that each tab (46) of the body is capable of sliding axially in one of said grooves.

Abstract: Insertable clamp (100), for the temporary assembly of at least two drilled structural parts (200a, 200b), including a main tubular body (10) extending along a longitudinal axis X and having a bearing surface (111) intended to come into contact with a first face (201a) of the structural parts, an elastic clip (30) capable of passing through drilled aligned holes, produced in said parts, the clip being translationally moveable along the longitudinal axis, driven by the rotation about said axis of a driver nut (50) provided with a tapped bore (51) cooperating with a threaded end (31) of said clip, the clip (30) comprising two branches (32) each ending by a hooking spur (33) intended to come into contact with a last face (202b) of the structural parts, said branches transversally and progressively moving apart along a spreader (40), placed between said branches and fixed in relation to the main body (10), when exposed to the recoil of the clip, the clamp further includes a compression spring (60) placed inside th

Abstract: The present invention concerns a fastening socket (112) for assembling at least two previously drilled structures, said socket comprising a substantially cylindrical body (34) and an enlarged head (35); said enlarged head comprising first mounting surfaces (42, 46) suitable for being assembled to a first installation component and for preventing said first installation component from rotating about the main axis. The socket comprises a first substantially cylindrical recess (40) extending along the main axis from the first end, said first recess ending at a planar shoulder (44) substantially perpendicular to said main axis, the first recess and the planar shoulder being received inside the enlarged head, the first mounting surfaces (42, 46) being formed by an inner surface of the first recess.
