  • Publication number: 20130264418
    Abstract: The invention relates to a method of managing an aircraft having undercarriages carrying a certain number of braked wheels, the aircraft including: a system for operating the undercarriages including raising actuators and latching actuators for the undercarriages and the associated hatches; a braking system including braking actuators for braking the wheels of the aircraft; at least one control unit for controlling the operation of the undercarriages and the braking; and at least one maintenance unit for selectively controlling at least some of the actuators of said systems while the aircraft is in a switched-off state during maintenance operations on one or another of the systems. According to the invention, the method includes the step of activating the maintenance unit while the aircraft is not in the switched-off state in order to use the maintenance unit for actuating actuators connected to the maintenance unit, in particular in the event of a failure of the control unit.

  • Publication number: 20130200212
    Abstract: The invention provides a control box for selectively delivering orders to receivers (8, 12), the control box comprising: a shaft (14) mounted to turn about an axis of rotation (X), while being capable of sliding along said axis (X) between a rest position towards which it is urged by return means (24), and an active position; order delivery means (16, 11) co-operating with the shaft (14) to deliver orders as a function of the angular position of the shaft (14); rotary drive means (15) for causing the shaft to turn; and safety actuation means (23) for causing the shaft to slide from the rest position in which anti-rotation means (27, 28) prevent the shaft from turning to the active position in which the anti-rotation means (27, 28) leave the shaft free to turn under drive from the rotary drive means (15).

  • Publication number: 20130167678
    Abstract: A device, which connects a gearmotor to an aircraft wheel, comprising: a casing rotatably carrying a shaft driven by the gearmotor, the shaft having a fluted portion on which a gearwheel is mounted to slide along a longitudinal axis of the shaft without rotating relative to the shaft; a toothed ring for constraining to rotate with the aircraft wheel; and means for moving the gearwheel axially between a retracted position (disengaged from the toothed ring) and an engaged position (gearwheel meshes with the toothed ring). The means for moving comprises a hollow screw-and-nut assembly extending around the shaft, one of the elements being axially secured to the gearwheel but prevented from rotating by an anti-rotation member, and the other element of the screw-and-nut assembly being rotatably mounted inside the casing to be driven selectively by an electric motor so that rotating the electric motor causes the gearwheel to move axially.

  • Publication number: 20130147210
    Abstract: The invention relates to a latching box for selectively retaining a movable element such as an undercarriage or a hatch in position, the box comprising a body carrying: a hook pivotally mounted about a first pivot axis between an engaged position and a disengaged position relative to the movable element; a locking member pivotally mounted about a second pivot axis parallel to the first pivot axis to pivot between a position for blocking the hook in the engagement position and a release position for releasing the hook; and at least one cam actuator in which the cam co-operates operationally with the locking member to move it towards the release position. The cam of the actuator is a cylindrical cam mounted to rotate about an axis of rotation orthogonal to the first and second pivot axes.

  • Publication number: 20130091969
    Abstract: A device for connecting a gear motor to an aircraft wheel, the device comprising: a casing rotatably carrying a shaft that is to be driven by the gear motor, and on which a pinion is mounted idle by means of a rolling bearing; a toothed ring for being constrained in rotation with the aircraft wheel and arranged to mesh permanently with the idle pinion; and rotation securing means for selectively constraining the idle pinion in rotation with the shaft. With this structure, a smooth bearing is interposed between the shaft and the rolling bearing of the idle pinion.

  • Publication number: 20130075527
    Abstract: The invention relates to a device for manoeuvring, on the ground, a door of an aircraft landing gear, the door being linked with door manoeuvring means and uplock means for locking the door when it reaches the closed position, at least one unlocking electromechanical actuator arranged to act upon the uplock means with a view to deactivating them during opening of the door in flight. According to the invention, the device comprises control means 17 which can be operated by an operator on the ground in order to control at least: an opening sequence during which the unlocking electromechanical actuator is actuated in order to deactivate the uplock means, a closing sequence during which the manoeuvring means are actuated in order to close the door again.
