摘要： A manufacturing method is described for a wind turbine blade, where layers of fiber material are laid up in a mold to form a portion of the blade structure. The fiber layers are infused with a resin which is subsequently cured to form the hardened blade structure. Some of the layers of fiber material are arranged so that a portion of the layers are kept resin-free during the infusion and curing steps, so that the fiber layer extends freely out from the external surface of the blade, preferably at the blade trailing edge, to provide a flexible blade trailing edge to reduce blade operational noise.

摘要： A control method for a wind turbine, in particular for a wind turbine blade is described. The control method makes use of the blade mode shapes, or natural vibration shapes, of the blade to detect the excitement level of the blade natural vibrations, and controls active lift devices on the blade in an effort to reduce the excitement levels, to reduce loading in the blade and the overall wind turbine structure. There is also provided a method of designing a wind turbine blade for use in such a method.
