Abstract: A wind turbine blade having a longitudinal direction with a root end and a tip end as well as a chord extending in a transverse direction between a leading edge and a trailing edge is described. The blade comprises a flow control surface with a suction side and a pressure side. A number of boundary layer control means is formed in the flow control surface. The boundary layer control means include a channel submerged in the flow control surface with a first end facing towards the leading edge and a second end facing towards the trailing edge of the blade. The channel comprises: a bottom surface extending from the first end to the second end, a first sidewall extending between the flow control surface and the bottom surface and extending between the first end and the second end, the first sidewall forming a first sidewall edge between the first side wall and the flow control surface, and a second sidewall extending between the flow control surface and the bottom surface and extending between the first end and the second end, the second sidewall forming a second sidewall edge between the second side wall and the flow control surface. The channel at the first end comprises a first flow accelerating channel zone adapted for accelerating a flow, and at the second end comprises a second channel zone, where the first sidewall and the second sidewall are diverging towards the trailing edge of the blade.

Abstract: A blade (10) for a rotor of a wind turbine having a profiled contour divided into: a root region (30), an airfoil region (34), and a transition region (32) between the root region (30) and the airfoil region (34). A shoulder (40) is located at the boundary between the transition region (32) and the airfoil region (34). 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 0-0.8L is at least 22%.

Abstract: A blade for a rotor of a wind turbine is divided into a root region closest to the hub and an airfoil region with a lift generating profile furthest away from the hub and a transition region. A base part of the transition region has an axial induction factor, which without flow altering device deviates at least 5% from a target axial induction factor. A number of first flow altering devices are arranged so as to adjust the aerodynamic properties of a longitudinal segment of the transition region to substantially meet the target axial induction factor.

Abstract: The present invention relates to a design concept by which the power, loads and/or stability of a wind turbine may be controlled by typically fast variation of the geometry of the blades using active geometry control (e.g. smart materials or by embedded mechanical actuators), or using passive geometry control (e.g. changes arising from loading and/or deformation of the blade) or by a combination of the two methods. The invention relates in particular to a wind turbine blade, a wind turbine and a method of controlling a wind turbine.
