Furthermore, it can be seen from FIG. 2 that, according to one embodiment of the invention, the wind deflector 3 is fastened to a rotatable bearing 7, which is rotatable about the tower 2.

Since, due to the use of a rotatable about the longitudinal axis of the tower rotatably mounted on this wind deflector no rapid changes of the aerodynamic load acting on the wings, also a generation of interfering acoustic pulses is reduced.
