Abstract
A wind turbine is operated with a blade in which a transition region is provided between a root region with a substantially circular or elliptical profile closest to a hub and an airfoil region with a lift generating profile furthest away from the hub. The transition region has a base part with an inherent non-ideal aerodynamic design so that a substantial longitudinal part of the base part without flow altering devices at a design point deviates from a target axial induction factor. A pitch of the blade and a rotational speed are adjusted to meet the target axial induction factor of the second longitudinal segment, and flow altering devices are provided so as to meet the target axial induction factor of the first longitudinal segment.
