  • Controlling aerodynamic spanload control devices
    Patent number: 10981643
    Abstract: 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.
    Type: Grant

  • LIFTING SURFACES AND ASSOCIATED METHOD
    Publication number: 20190322354
    Abstract: An arrangement of lifting surfaces including a primary lifting surface having a flexural axis extending in the spanwise direction of the lifting surface, a root, and a tip. A first tip device is attached to the tip and has a first lifting surface. A second tip device is attached to the tip and has a second lifting surface. A control system is coupled to the first and second tip devices for moving the first and second lifting surfaces relative to the tip and/or for actively controlling circulation of the first and second lifting surfaces. The control system is operable to change a value of torque effective at the primary lifting surface about the flexural axis. Also, a method of controlling an arrangement of lifting surfaces.
