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.

Abstract: A wind turbine blade (10) comprising a pressure side (24) and a suction side (26), a leading edge (18) and a trailing edge (20). At least a portion of the blade (10) located in a trailing edge region (142) at or adjacent to the trailing edge (20) is a noise reducing portion defining an exposed surface and comprising a plurality of sound reducing or sound absorbing acoustic resonators (58), each of the resonators (58) comprising an opening (55) in the exposed surface and a cavity (56) having a length L between the opening (55) and a bottom (57) of the cavity opposite the opening (55).

Abstract: A wind turbine blade measurement system for optically determining a torsion of a wind turbine blade is disclosed. The wind turbine blade measurement system comprises: a wind turbine blade, which is configured to be mounted to a hub of a wind turbine, a first camera, and an auxiliary camera. The first camera is mounted in a fixed position on a support structure on an exterior surface of the root section of the wind turbine blade and arranged so as to measure along the spanwise direction of the wind turbine blade. The auxiliary camera is arranged at a position outside of the wind turbine blade, the auxiliary camera being arranged so as to being able to carry out measurements of a plurality of sets of markers arranged on the surface of the wind turbine blade and an orientation of at least one of the support structure and the first camera.

Abstract: A wind turbine blade includes a leading edge protection element attached to the leading edge of the wind turbine blade. The leading edge protection element extends in a longitudinal direction between an outboard end and an inboard end and includes an attachment surface mounted to an exterior surface of the blade, an exterior surface opposite the attachment surface, a first section extending from the leading edge and along a part of the pressure side of the wind turbine blade to a first transverse end at a first position on the pressure side of the blade, and a second section extending from the leading edge and along a part of the suction side of the wind turbine blade to a second transverse end at a second position on the suction side of the blade.
