摘要： A wind turbine has a longitudinal airfoil blade that exerts a torque on the generator in response to an impinging air current. A compliant airfoil edge arrangement is disposed along an edge of the airfoil blade for at least a portion of a longitudinal dimension of the airfoil blade. A morphing drive arrangement varies a configuration of the compliant airfoil edge arrangement and consequently the aerodynamic characteristics of the airfoil blade. A drive arrangement applies actuation forces to the upper and lower compliant surfaces via the upper and lower actuation elements. The compliant airfoil edge is arranged as a trailing edge of the airfoil blade.

摘要： Variation in the contours of first and second compliant surfaces is produced by a compliant frame having a first resiliently variable frame element ( 120 ) having a corresponding first outer surface ( 122 ) and a first inner surface ( 124 ), and a second resiliently variable frame element ( 130 ) having a corresponding second outer surface ( 132 ) and a second inner surface ( 134 ). The first and second outer surfaces ( 122, 132 ) communicate with respective ones of the first and second compliant surfaces. A linkage element ( 141 - 144 ) having a predetermined resilience characteristic is coupled at a first end thereof to the first inner surface ( 124 ) and at a second end thereof to the second inner surface ( 134 ). A frame coupler ( 151 ) couples the first resiliently variable frame element ( 120 ) to a support element ( 150 ). An actuator ( 106 ) applies a force to the second resiliently variable frame element ( 130 ) with respect to the support element (150), resulting in a corresponding variation in the contour of the first and second compliant surfaces.

摘要： A windshield wiper system includes a windshield wiper having a wiper blade with a near end and a far end. The windshield wiper is configured for performing a relative rotation of the wiper blade between the far end and the near end of the wiper blade. A mechanism applying a torque to the far end during a sweeping motion of the windshield wiper twists the far end of the wiper blade relative to the near end. The mechanism may perform the relative rotation of the wiper blade regardless of whether the wiper blade is in contact with a windshield. For example, the mechanism may include a stationary cam block having a cam profile, and an actuator arm moving along the cam profile with the sweeping motion of the windshield wiper. The cam profile is suitably shaped to pivot the actuator arm in laterally outer ranges of the sweeping motion.

摘要： An edge morphing arrangement for an airfoil having upper and lower control surfaces is provided with a rib element arranged to overlie the edge of the airfoil. The rib element has first and second rib portions arranged to communicate with respectively associated ones of the upper and lower control surfaces of the airfoil. A first compliant linkage element has first and second ends and is disposed between the first and second rib portions of the rib element, the first and second ends are each coupled to the interior of a respectively associated one of the first and second rib portions. There is additionally provided a driving link having first and second driving link ends, the first driving link end being coupled to the interior of a selectable one of the first and second rib portions in the vicinity of the coupling of the respectively associated end of the first compliant linkage element. The second end is arranged to receive a morphing force, and the rib element is deformed in response to the morphing force. Multiple rib elements can be arranged substantially parallel to one another and configured to morph at respective operating ratios. Additionally, an overlying skin has a thickness that varies over the span.
