Abstract
Systems and methods for actuating a control surface which is pivotably coupled to a trailing edge of an aircraft wing. The control surface actuation system has a compact footprint and high capability. The control surface actuation system includes a rotatable torque shaft that is coupled (by means of meshed surfaces) to the control surface so that rotation of the torque shaft by a deflection angle causes the control surface to pivot by an equal deflection angle. Rotation of the torque shaft is actuated by a pair of redundant mutually opposing actuation mechanisms. The redundant actuation mechanisms are situated inside of the fuselage, while the torque shaft is disposed partly inside the fuselage and partly inside the control surface.
