ABSTRACT:
A wing twist deformation control mechanism which provides active compensation for aerodynamically induced twist deformation of high aspect ratio wings. The twist deformation control mechanism consists of a torque tube, internal to each wing and rigidly attached near the tip of each wing, and moved by an actuator located in the aircraft fuselage. As changes in the aerodynamic loads on the wings occur the torque tube is rotated to compensate for the induced wing twist.
