  • Patent number: 11808463
    Abstract: A heatable floor panel for an aircraft, with a supporting level, a heat-generating level and a heat-conducting level. The heat-generating level comprises a fiber composite layer with fibers and with a matrix surrounding the fibers. The fibers are at least partially formed as conducting fiber, and the conducting fibers are formed as carbon fibers with an electrically insulating coating. The conducting fibers integrated in the floor panel in order to conduct a heating current through them. Due to the electrically insulating coating of the conducting fibers, leakage currents are avoided. The carbon fibers serve not only as heating elements, but, at the same time, also as reinforcing fibers of the fiber composite layer or of the floor panel.

  • Patent number: 11806938
    Abstract: A method for manufacturing a component by stacking layers of material that are each obtained by depositing and melting, continuously, a material by virtue of an energy beam of which at least one feature is controlled by a control current intensity. The manufacturing method includes a step of monitoring the control current intensity, a step of comparing the monitored control current intensity with a given threshold and a step of stopping the manufacturing method when the control current intensity is above the given threshold. This momentary stopping of the method makes it possible to significantly reduce the risks of energy runaway liable to destroy the deposited material bead and the neighboring structure.

  • 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.

  • Publication number: 20230339593
    Abstract: An aircraft fuselage is configured to receive two tanks designed to contain liquid hydrogen. The fuselage includes a first section for a cockpit, a second section for a passenger cabin and a third section (T3) distinct from the first section (T1) and from the second section (T2). The third section (T3) includes two housings each to house a tank. The two housings are arranged symmetrically with respect to a vertical plane of symmetry (P1). This arrangement of the tanks in a section distinct from the other sections allows them to be located as close as possible to the motors that they have to supply.

  • Patent number: 11788832
    Abstract: A method for parameterizing a photogrammetric cable robot, having a frame, a mobile platform carrying a camera and cables, each cable extending from a mobile platform attachment point to a position-adjustable exit point, while remaining linked to the frame. The robot's maximum workspace is defined by the ranges of possible positions of the different cable exit points. A set of pairs of setpoint positions and orientations of the platform is determined, for performing the point measurements of a scene by photogrammetry. Then, a genetic algorithm comprising crossing, transformation and selection operations is applied to a population of vectors, each representing respective positions of cable exit points, the selection being made via a fitness function involving a first objective function evaluating a collision percentage and a second objective function evaluating a percentage violation of a mobile platform constraint of equilibrium, when the platform assumes the different setpoint positions and orientations.

  • Patent number: 11780558
    Abstract: A support stay is provided to improve failsafe configurations for movable parts of an aircraft. The support stay supports the movable part with a primary body and a separate secondary body. The primary body and the secondary body provide separate load paths. The secondary body is attached to the primary body by a mechanical connection, e.g., rivets. If one of the bodies becomes structurally compromised, for example by a crack, this configuration does not transfer shear load between the primary and secondary body, so that the other body does not become structurally compromised.
