Abstract: The invention relates to a system for the local surface treatment of an aeronautical part (1) to be treated. Said system is characterised in that it comprises a plurality of containers (18, 19, 20, 21) each comprising a treatment product (22, 23, 24, 25), at least one bath enclosure (102a, 102b) suitable for delimiting a fluid-tight space (26a, 26b) between this bath enclosure (102a, 102b) and a portion (101a, 101b) of the part to be treated, and a controlled circuit (10) for supplying said fluid-tight space (26a, 26b) with treatment product (22, 23, 24, 25) the containers (18, 19, 20, 21) connecting at least this container (18, 19, 20, 21) to said fluid-tight space (26a, 26b) and comprising valves for managing the supply to the fluid-tight space by one or more containers from the plurality of containers.

Abstract: An aircraft structure (10), in particular the fuselage, nacelles or wings, includes, over all or part of an outer surface (21) that may undergo lightning impacts, a layer of flexible polymer (30), a photovoltaic film (40) and a protective layer (50) protecting the photovoltaic film. This aircraft structure primarily has a solar energy capture capacity making it possible to meet the needs of an aircraft as well as an ability to protect against the effects of lightning.

Abstract: This relates to a process for manufacturing a microstructured coating on a substrate, which comprises a step of spraying molten particles having a diameter comprised between 0.05 ?m and 5 ?m onto the substrate, the spraying being carried out by at least one plasma torch, which is moved relative to the substrate, the movement parameters and/or the flowrate of particles sprayed by the plasma torches being variable as a function of the position of the plasma torches, ensuring a variable thickness for the coating formed by the particles, at various points of the substrate. The embodiment also relates to a wall having a coating obtained by this process.

Abstract: The embodiment relates to a process for manufacturing a resistive layer for an acoustic panel, comprising a step of manufacturing a wall containing apertures distributed over its surface, making it air-permeable, and a step of depositing, on a face of said wall, particles of diameter comprised between 0.05 ?m and 5 ?m, until a coating of thickness comprised between 0.02 mm and 0.5 mm is formed on this face, partially blocking the apertures.
