A blade (1) for a wind turbine comprising a root segment (12) for connection to a hub and a profiled segment (10) extending in a longitudinal direction from the root segment towards a tip of the blade. It is an object of the invention to provide a blade with a root segment contributing to the generation of lift. The blade comprises at least one guide vane (20) with a vane leading edge (22) and vane trailing edge (23) on the suction side. One could say that the vane leading edge (22) is oriented towards the leading edge of the blade and the vane trailing edge (23) looks in the direction of the trailing edge of the blade. This guide vane is arranged in such that the guide vane is substantially placed over the blade surface and extends in longitudinal direction at least partly along the surface of the root segment. |
