  • Patent number: 12005665
    Abstract: A device for manufacturing a stiffened panel with reinforcements which each have a final thickness and a final height. The manufacturing device includes tools configured to each support a preform of fibers having a U-shaped or C-shaped cross section with a base and two wings. Each tool comprises, at at least one of its first and second lateral faces, a set-back portion which, when two tools are juxtaposed, delimits a recess configured to form a reinforcement during a consolidation or polymerization step. The tools are dimensioned such that each recess has a width, at the consolidation or polymerization temperature, that is substantially equal to the thickness of the reinforcements. This solution makes it possible to more effectively control the geometry of the stiffened panel by avoiding the formation of beads. A method for manufacturing a stiffened panel using the device is also disclosed.

  • Patent number: 11945569
    Abstract: An anchor rail for an aircraft floor includes an upper flange with a guideway and two flange wings. The rail is formed of a beam and of an anti-corrosion protection. The beam is formed at least of a body made from a first material and defining the lower stiffening structure and an upper platform. The anti-corrosion protection wholly covers an upper face of the upper platform and therewith constitutes the upper flange of the rail, thus layered. The anti-corrosion protection is at least formed of a protective sheet made of a second material more resistant to corrosion than the first material and selected from a metal and a fiber-reinforced plastic composite material. Such a rail exhibits good corrosion resistance for modest cost.

  • Patent number: 11803956
    Abstract: A method for detecting potential dents in a surface includes providing a flying drone with an image acquisition device and a light source, the shape of which is elongate, and a data processing device. At least one series of images is acquired of portions of the surface by the image acquisition device by moving the flying drone past the surface along a trajectory so that, for each image of the series, the light source is illuminating the corresponding portion of the surface. The data processing device is operated to analyze the shape of a specular reflection of the light source in images of the series of images to estimate the position of any dents in the surface.
