A wind turbine blade includes a profiled contour with a leading edge and a trailing edge, and a chord extending between the leading edge and the trailing edge, along with a blade shell with a pressure side and a suction side, a first main spar cap integrated in the pressure side of the blade shell, a second main spar cap integrated in the suction side of the blade shell, and one or more shear webs connected between the first main spar cap and the second main spar cap. The blade shell includes at least a first load carrying structure arranged at the leading edge or the trailing edge and having a first extension, including a first primary extension on a first side of the chord, where the first primary extension is at least 60% of the first extension.

Wind turbine blade and method of manufacturing a wind turbine blade

A wind turbine blade comprising a plurality of spar components extending along the longitudinal axis and providing the main bending stiffness of the wind turbine blade a major principal axis defining a structural pitch angle of at least 1° with respect to a chord line, and including: one or more suction-side spar caps each having a centre line; one or more pressure-side spar caps each having a centre line; and one or more shear webs distributed around a central shear web line and at least one of which being connected to first spar caps, wherein at least one suction-side spar cap centre lines is arranged with a first chordwise distance to the central shear web line, and at least one pressure-side spar cap centre lines is arranged with a second, different, chordwise distance to the central shear web line.

Aeroelastic stable wind turbine blade

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.

Wind turbine blade and an associated manufacturing method

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.

Wind turbine blade control method

A blade () for a rotor of a wind turbine having a profiled contour divided into: a root region (), an airfoil region (), and a transition region () between the root region () and the airfoil region (). A shoulder () is located at the boundary between the transition region () and the airfoil region (). The blade's profiled contour comprises a local relative thickness defined as the local ratio between a maximum profile thickness (t) and the chord length (c). The ratio between the shoulder width (W) and the blade length (L) being less than or equal to 0.075, and the relative thickness (t/c) in a blade length interval of 0-0.8 L is at least 22%.
