Abstract
A wind turbine comprising one or more wind turbine blades arranged to perform pivot movements between a minimum pivot angle and a maximum pivot angle, each wind turbine blade extending between an outer tip and an inner tip, wherein each wind turbine blade has an outer portion extending between the hinge and the outer tip and having a first length, and inner portion extending between the hinge and the inner tip and having a second length, wherein a coning angle of the blade carrying structure is larger than zero and/or a tilt angle of the rotor axis is larger than zero, and wherein a horizontal distance from the tower at a vertical position defined by a position of the hinge at tower passage to a point of connection between the blade carrying structure and the hub is equal to or less than the second length.
