Abstract
A wind turbine () comprising a tower (), a nacelle () and a hub () is disclosed. The hub () comprises a blade carrying structure () with one or more wind turbine blades () connected thereto. Each of the wind turbine blades () defines an aerodynamic profile having a chord which varies along a length of the wind turbine blade (). Each of the wind turbine blades () is connected to the blade carrying structure () via a hinge () at a hinge position of the wind turbine blade (), each wind turbine blade () thereby being arranged to perform pivot movements relative to the blade carrying structure () between a minimum pivot angle and a maximum pivot angle. The hinge position is arranged at a distance from the inner tip end () and at a distance from the outer tip end (), and the chord at the hinge position is larger than or equal to the chord at the inner tip end () and larger than the chord at the outer tip end ().
