Abstract: An aircraft is provided. The aircraft includes fuselage, an aerodynamic element extending from the fuselage and including a main section and an adjustable section which is adjustable relative to the main section, a power distribution unit (PDU) configured to generate torque to drive an adjustment of the adjustable section, an actuator, torque tubes and elastomeric couplings. The PDU is disposed proximate to a fuselage-aerodynamic interface. The actuator is disposed along the aerodynamic element and is receptive of the torque for driving the adjustment of the adjustable section. The torque tubes transmit the torque from the PDU to the actuator and are arranged between the PDU and the actuator such that adjacent torque tubes define an obtuse angle. The elastomeric couplings are disposed at respective ends of each of the torque tubes to enable torque transmission between at least the adjacent torque tubes defining the obtuse angle.

Abstract: A method for braking a motor in a high lift system of an aircraft, the high lift system comprising a central power drive unit for moving high lift surfaces arranged at a wing through providing rotational power by means of a transmission shaft to a plurality of drive stations operably coupled with the high lift surfaces; which power drive unit is operatively coupled to a controller and comprises at least one electric motor coupled therewith. The method includes determining a braking requirement for the at least one electric motor, measuring at least one of a current command to the motor and a current speed and direction of the at least one electric motor, based on the braking requirement, applying a braking command to the at least one electric motor, and reducing the braking command as the at least one electric motor comes to rest.

Abstract: A predictive system is provided and include a torque-limiter, a sensor disposed to sense a condition of the torque-limiter and a processing system. The processing system is coupled to the sensor and configured to process readings of the sensor, to calculate whether the condition of the torque-limiter is indicative of degradation or failure incidents based on the readings being processed and to determine whether an action should be taken based on a calculation result.

Abstract: A method of prognostic health monitoring is provided for use with an aircraft. The method includes performing real-time monitoring of torque generated for controlling positions of controllable surfaces at right- and left-hand-sides (RHS and LHS) of the aircraft, generating RHS and LHS torque information from results of the monitoring and comparing the RHS and LHS torque information at least with each other or with corresponding historic torque information.
