  • Actuator system in an aircraft for monitoring a no-back brake
    Patent number: 11225314
    Abstract: The present invention relates to an actuator system in an aircraft for monitoring a no-back brake, which system comprises an actuator for actuating a flap of a flight control system of the aircraft, a first torque sensor for detecting a torque on the drive side of the actuator, and a second torque sensor for detecting a torque on the output side of the actuator, wherein the actuator is provided with an auto-switching no-back brake to hold the flap actuated by the actuator in position. The actuator system further has a monitoring unit, which is connected to the first torque sensor and the second torque sensor and is designed to detect an acute or imminent fault condition of the no-back brake depending on an actuator state and the detected torque values of the first torque sensor and the second torque sensor.
