Abstract
A wind turbine () comprising a tower (), a nacelle () mounted on the tower () via a yaw system, a hub () mounted rotatably on the nacelle (), the hub () comprising a blade carrying structure (), and one or more wind turbine blades () connected to the blade carrying structure () via a hinge () is disclosed. Each wind turbine blade () is thereby arranged to perform pivot movements relative to the blade carrying structure () between a minimum pivot angle and a maximum pivot angle. The blade carrying structure () is provided with one or more elements () configured to improve aerodynamic properties of a surface of the blade carrying structure () by increasing a lift and/or decreasing a drag of the blade carrying structure. The increase in lift and/or decrease in drag varies as a function of angle of attack (AOA) between the blade carrying structure () and the incoming wind.
