<p>A wind power plant comprises a blade rotor (1) rotating about a substantially horizontal axis (3) and a generator directly or indirectly driven by the blade rotor, said blade rotor being in a conventional manner intended, in a preferred operating position, to be disposed with its rotation axis (3) directed substantially parallel to the wind direction. In the direction of the rotation axis (3) and in said operating position close behind the propeller blades (2), as viewed in the direction of the wind, at least one screen (8) is so arranged to present surfaces for such a guiding of air streams striking thereupon in the direction of the rotation axis (3) of the blade rotor, that these air streams while co-operating with the propeller blades (2) make a contribution to the power driving the latters and generated as a result of the blade angle thereof.</p> |
