ABSTRACT OF THE DISCLOSURE A windmill for generating electricity in which each blade of the air-screw is connected to the hub by means of at least two resilient strips which are oppositely inclined both in the plane of rotation of the blade and in a plane extending through the rotational axis of the hub. This arrangement results in automatic pitch increase of the blades with higher increase air-screw rotation due to the increasing centrifugal force exerted on the blades, This regulates air-screw speed and prevents excessive speed, especially at low load. this pitch-varying mechanism can also be applied top automotive cooling fans. In accordance with another characteristic, the windmill proper consisting of the air-screw and the electric generator driven thereby, is attached to the supporting tower by a spring system, whereby any shock imparted to the windmill by wind gust, or sudden changes of direction of the wind, will be absorbed by this resilient mounting, thereby diminishing the stresses imparted to the support tower.
