Abstract

The wind turbine has a rotor which is rotatably, around a substantially vertical rotational axis, and functionally coupled to a stator for generating energy. The rotor comprises at least one blade, and a rotor frame for supporting the blades. The wind turbine is characterized in that, in operation of the wind turbine, the blades are freely pivotally coupled to the rotor frame in at least flapping.
