  • Patent number: 7865289
    Abstract: A method of distribution braking between the brakes of an aircraft. The method includes a first step of estimating a braking force objective and a steering torque objective to be achieved by the brakes of the aircraft. It also includes the steps of defining at least two groups of brakes (12, 13) and determining, for each group, a braking level that is to be achieved by the group. The braking levels being calculated in such a manner that braking performed in application of the braking levels is, at least under normal operating conditions of the brakes, in compliance with a braking force objective and with a steering torque objective.

  • Patent number: 7683274
    Abstract: The invention relates to a force-measurement cell for insertion in a bore of a pin, the cell comprising a bushing: having a generally cylindrical tubular wall with an outside surface adapted to extend against an inside surface of the bore in the pin; and within which there extends at least one sensor suitable for measuring at least one parameter representative of the stresses to which the wall is subjected. The invention also relates to a pin provided with such a force-measurement cell.

  • Patent number: 6954692
    Abstract: The invention relates to a method of managing a braking system architecture for an airplane fitted with brakes having electromechanical actuators, in which some of the actuators are connected to a battery assembly of the airplane and other actuators are not connected to the battery assembly of the airplane, which method comprises a step of controlling at least one of the actuators that is not connected to the battery assembly to cause it to exert a force equal to a unit holding force, which force is determined independently of any braking demand from the pilot. The invention also provides an architecture specially adapted to implement the method.
