  • Patent number: 11162551
    Abstract: The invention relates to a method for attenuating vibrations of an aircraft wheel/brake assembly arising during braking, the brake comprising rotor discs (2b) rotationally driven with the wheel by means of bars (5) secured to the wheel and engaging in notches (3b) of the rotor discs, and stator discs (2a) which are kept rotationally immobile by means of tenons (5) secured to a torque tube (1) of the brake and engaged in notches (3a) of the stator discs, the notches having flanks that are protected by brackets (7). The method involves selecting bracket/tenon pair and/or bracket/bar pairs with a coefficient of friction less than or equal to 0.6.

  • Patent number: 10676179
    Abstract: The invention relates to an electromechanical braking method for an aircraft having at least one electromechanical brake 2 fitted to at least one braked wheel 1 of the aircraft, the brake 2 having friction members 3 and a plurality of electromechanical actuators 4, each actuator 4 comprising a pusher 5 suitable for being moved by means of an electric motor 6 to selectively apply a pressing force on the friction members 3. According to the invention, for a given braking operation, a total braking force to be applied against the friction members 3 of the brake is distributed in non-uniform manner amongst the actuators 4 of the brake, such that at least two actuators 4 apply respective different forces.
