Abstract
An aircraft wing having a fixed wing with a tip, and a wing tip device rotatably mounted on a hinge at the tip of the fixed wing. The wing tip device is rotatable about the hinge. An actuation system rotates the wing tip device about the hinge. The actuation system has a motor, a plurality of geared mechanical actuators, and an angle gearbox coupled between the plurality of geared mechanical actuators and the motor. Each geared mechanical actuator is driveable by the motor and arranged to convert rotary motion into a different rotary motion. Each geared mechanical actuator is arranged along a hinge line of the hinge. The angle gearbox is arranged along the hinge line and between two of the plurality of geared mechanical actuators.
