A vortex generator device for a wind turbine blade, and a wind turbine blade is disclosed, the vortex generator device comprising a base with an inner side and an outer side, and a first fin protruding from the outer side and extending along a first fin axis, wherein the vortex generator device is a single-fin vortex generator device, and the base has a first edge part and a second edge part, the first edge part and the second edge part forming a primary angle in the range from 5 degrees to 60 degrees.

Vortex generator device for a wind turbine blade

This invention relates to a root end structure, a wind turbine blade comprising such a root end structure and a method of manufacturing such a wind turbine blade. The root end structure comprises a plurality of fastening members distributed along a root end of a blade part, wherein a first plurality of pultruded elements are arranged in between the fastening members and a second pultruded element is further arranged at the blade joint ends adjacent to an outermost fastening member. Each first pultruded element has opposite facing second sides each facing a first side of an adjacent fastening member. The second pultruded element has one second side facing the outermost fastening member and another second side facing the blade joint interface. The second pultruded element comprises a transition portion forming a smooth transition for the inner layers extending further along the mould edge surface.
