Abstract
A method and a device for manufacturing a structural and/or acoustic panel for a nacelle of an aircraft propulsion assembly involves heating, by producing electromagnetic radiation, at least one skin of the structural and/or acoustic panel in such a way as to assemble this skin with a cellular structure of the structural and/or acoustic panel, by diffusion brazing or welding. This heating device can also be used to shape the skin to the cellular structure prior to assembly.
Claims6
A method for manufacturing a structural and/or acoustic panel for a nacelle of an aircraft propulsion unit, the structural and/or acoustic panel comprising two metallic skins and a metallic cellular structure, the method comprising an arrangement of one of the two metallic skins, called a working skin, such that the working skin delimits a first volume and a second volume of an enclosure, and an arrangement of the metallic cellular structure within the second volume of the enclosure, wherein the method further comprises heating the working skin by infrared electromagnetic radiation so as to assemble the working skin and the metallic cellular structure by at least one of brazing and diffusion-welding.
A device for manufacturing a structural and/or acoustic panel for a nacelle of an aircraft propulsion unit, the structural and/or acoustic panel comprising two metallic skins and a metallic cellular structure, the device comprising an enclosure adapted to receive one of the two metallic skins, called a working skin, such that the working skin delimits a first volume and a second volume of the enclosure, the enclosure being adapted to receive the metallic cellular structure within the second volume, wherein the device further comprises a heating device arranged so as to heat the working skin by infrared electromagnetic radiation so as to assemble the working skin and the metallic cellular structure by at least one of brazing and diffusion-welding during assembly.
