US Patent 10981643 Controlling aerodynamic spanload control devices

An aerodynamic structure is disclosed having a lifting surface, a control device and an actuation mechanism. The lifting surface has a root and a tip, and is deformable during operation of the aerodynamic structure. The control device is movably attached to the lifting surface, at or near the tip. The actuation mechanism is for controlling movement of the control device, and is configured to transmit deformation movement of the lifting surface to the control device.
