<p>The present invention is a wind turbine comprising double functioning wings/blades (1) wherein total efficient field is increased by inserting the parts, rotating against the wind, of the said double wings (1) rotating in opposite directions (3), one within the other, sol that the obstructive area (7) of such blades are restrained in a single wing size. The function of the wind front-barrier is to reduce the wind pressure formed on the preventive-field ant to facilitate the reverse direction revolution.</p> |
