Abstract: A method and a device for manufacturing a part starting from a cushion made of deformable material, in particular for an edge of an element of an aircraft. The device includes a preparation unit to create a cushion with two plates and, between the plates, an internal space with an opening, and a molding unit comprising a mold in which the cushion is positioned, the mold comprising two shells and an imprint corresponding to the shape of the part to be manufactured, the molding unit configured to inject a pressurized fluid into the internal space of the cushion through the opening to deform the cushion such that it matches the imprint and forms the part, the device being capable of manufacturing one-piece parts of various sizes, and in particular parts having complex shapes, in particular non-developable shapes.

Abstract: An acoustic absorption structure includes: a porous layer in contact with a medium through which the sound waves travel, a cellular layer including a plurality of cells, which has at least one exterior annular canal open towards the porous layer, and a reflective layer. An aircraft propulsion system having at least one such acoustic absorption structure is also described.

Abstract: Method and device for manufacturing a component from a plate made of deformable material, in particular for an edge of an element of an aircraft. The device includes a tool with two tool parts configured to be able to move closer to one another and are able to round a plate made of deformable material fixed to the two tool parts, a mold at the periphery of the tool and including a molding cavity of a shape corresponding to the shape of the component that is to be manufactured, and a displacement system configured to press the rounded plate firmly against the molding cavity of the mold, the mold being able to shape the rounded plate when it is pressed firmly against the molding cavity to give it its definitive shape, the device allowing the manufacture of single-piece components of varying sizes and notably large-sized components and/or deep components.
