  • Patent number: 11945571
    Abstract: A piloting device arranged to be integrated in a pre-existing aircraft that includes original systems comprising both a flight control system and an autopilot system is distinct from and autonomous relative to the original systems and includes a positioning unit and a control unit. The positioning unit is arranged to produce positioning data for the pre-existing aircraft. The control unit is arranged to perform a geofencing function from the positioning data produced by the positioning unit and to produce an alternative piloting setpoint for the pre-existing aircraft. The alternative piloting setpoint is adapted to supplement both a manual piloting setpoint produced by a pilot of the pre-existing aircraft via the flight control system and also an autopilot setpoint produced by the autopilot system.

  • Patent number: 10597171
    Abstract: A method is provided for characterizing the amplitude of play in an electromechanical actuator comprising an electric motor, a movable element, an upstream sensor, a downstream sensor, and a force sensor. The method includes steps of measuring the position of the motor, the position of the movable element and the load applied to the movable element using the three sensors. On the basis of a computer model of the actuator and of the measurements, a value of the amount of mechanical play is estimated using a state observer considering the play to be a state component. The amplitude of the play is determined from a set of values of the dynamic variable obtained in the preceding step at various times.

  • Patent number: 10451502
    Abstract: The invention relates to a method of monitoring an electromechanical actuator system, the method comprising the steps of estimating the voltage drop in the power supply to the motor associated with defects of the inverter by means of a Kalman filter, estimating (300) at least the electromagnetic torque coefficient of the motor by taking account of the estimated voltage drop, and calculating (400) the electromagnetic torque of the motor from the electromagnetic torque coefficient of the motor.
