Abstract
The invention relates to a pitch controlled wind turbine blade including a pressure surface side and a leeward surface side, where the surfaces establishes a leading edge and a trailing edge. The blade includes a turbulence generating mechanism where the mechanism is placed on the leeward surface sides of the wind turbine blade and at the outer section of the wind turbine blade in direction of the blade tip. The invention further relates to a wind turbine including at least two pitch controlled wind turbine blades and a pitch controlling mechanism for pitching the blades. The blades include a turbulence generating mechanism where the mechanism is placed on the leeward surface sides of the wind turbine blades and at the outer section of the wind turbine blades in direction of the blade tips.
