| description | A wind turbine (1) comprising a tower (2), a nacelle (3) mounted on the tower (2) via a yaw system, a hub (4) mounted rotatably on the nacelle (3), the hub (4) comprising a blade carrying structure (5), and one or more wind turbine blades (6) connected to the blade carrying structure (5) via a hinge (7) is disclosed. Each wind turbine blade (6) is thereby arranged to perform pivot movements relative to the blade carrying structure (5) between a minimum pivot angle and a maximum pivot angle. The blade carrying structure (5) is provided with one or more elements (8) configured to improve aerodynamic properties of a surface of the blade carrying structure (5) 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 (5) and the incoming wind. |
