Abstract: A blade for a rotor of a wind turbine, the blade comprising: an inboard portion; an outboard portion connected to the inboard portion, wherein the outboard portion is deflectable by a variable sweep angle in an edgewise direction of the blade; and a passive mechanism configured to adjust the sweep angle in response to an amount of flapwise moment acting on the blade, such that the magnitude of the sweep angle increases in response to an increased flapwise moment, and decreases in response to a decreased flapwise moment.

Abstract: A trailing edge panel is configured to be attached to a trailing edge of a wind turbine blade and includes a base element and a number of protruding aerodynamic elements. The base element has an attachment part configured to be attached to and extend from the trailing edge of the wind turbine blade and to an upstream position on a first blade side of the wind turbine blade. The base element further has a serrated part extending from the second side of the attachment part and configured to project out from the trailing edge of the wind turbine blade, wherein the serrated part comprises a number of serrations, including a first serration and a second serration. The number of protruding aerodynamic elements, including a first protruding aerodynamic element, includes a first protruding part attached to the serrated part of the base element.
