  • Method and system allowing automatic take-off of an aircraft
    Patent number: 11687097
    Abstract: A method and system allowing fully autonomous automatic take-off using only images captured by cameras on the aircraft and avionics data. The system includes an image capture device on the aircraft to take a stream of images of the runway, image processing modules to estimate, on the basis of the streams of images, a preliminary current position of the aircraft on the runway and to assign a preliminary confidence index to the estimate. A data consolidation module can determine a relevant current position of the aircraft on the runway by consolidating data originating from the image processing modules with inertial data to correct the estimate of the preliminary current position and determine a relevant confidence index using a current speed of the wheels of the aircraft to refine the preliminary confidence index. A flight control computer can control and guide aircraft take-off.

  • Assembly for an aircraft, the assembly having a pylon and a wing
    Patent number: 11679861
    Abstract: An assembly having a pylon with an upper spar and four lateral scoops, a wing with a skin, longitudinal spars and fittings, and, for each lateral scoop, two fastening assemblies, wherein the skin and the fitting each have a first bore and wherein the upper spar and the lateral scoop each have a second bore, wherein each fastening assembly has a screw passing through the first and the second bores, a nut, two eccentric rings, threaded onto one another and onto the screw, and a system for stopping the eccentric rings rotating. The assembly makes it possible to dispense with the use of the spigots while also ensuring the reaction of the shear forces contained in the XY plane by the bolts on account of the reduced tolerances between the various bores, the external and internal surfaces of the eccentric rings and the plain zones of the screws.

  • Conveying installation and tool head for an additive manufacturing machine, and additive manufacturing machine
    Patent number: 11667077
    Abstract: For increasing the speed in 3D printing, for avoiding the conveying elements slipping from the conveyed semi-finished product, and for improving the transmission of force from the conveying elements to the semi-finished products to be conveyed, a conveying installation is provided for an additive manufacturing machine. The conveying installation for conveying a semi-finished product comprises a longitudinal conveying mechanism which by means of a periodic movement of at least one conveying element conveys the semi-finished product along a conveying direction which is parallel to the semi-finished product longitudinal axis. The conveying element when moving in the conveying direction acquires the semi-finished product, and when moving counter to the conveying direction is released from the semi-finished product. This results in a movement of the semi-finished product in the conveying direction.
