Wind turbine blade with base part having non-positive camber

A blade for a rotor of a wind turbine having a substantially horizontal rotor shaft, the rotor comprising a hub, from which the blade extends substantially in a radial direction when mounted to the hub, the blade having a predetermined target axial induction factor at a rotor design point, the blade comprising:

• a profiled contour comprising a pressure side and a suction side as well as a leading edge and a trailing edge with a chord extending between the leading edge and the trailing edge, the profiled contour generating a lift when being impacted by an incident airflow,
• the profiled contour in the radial direction being divided into a root region with a substantially circular or elliptical profile closest to the hub, an airfoil region with a lift generating profile furthest away from the hub, and preferably a transition region between the root region and the airfoil region, the transition region having a profile gradually changing in the radial direction from the circular or elliptical profile of the root region to the lift generating profile of the airfoil region, characterised in that
• the airfoil region is divided into a number of base sections, a first one of said base sections extending along at least 20% of a longitudinal extent of the airfoil region, the first base section having a leading edge and a trailing edge with a chord extending between the leading edge and the trailing edge,
• the first base section being formed with a cross-sectional profile, which when being impacted by an incident airflow at an angle of attack of 0 degrees has a lift coefficient, which is 0 or less, a positive lift being defined as a lift coefficient having a lift component directed from the pressure side towards the suction side of the blade, and a negative lift coefficient being defined as a lift coefficient having a lift component directed from the suction side towards the pressure side of the blade.
