Patent ID: 7198469

Claim:
A wind generator of the type with automatic power regulation comprising at least two blades of at least one propeller, the efficiency of a propeller varying inversely with respect to the variation of the energy of the wind, starting from a lower limit of the speed of the wind, the torque/speed characteristics of each propeller being determined such that the operating point starts to move towards the zones of low aerodynamic efficiencies when the speed of the wind approaches the value for which the generator reaches the maximum power compatible with safety, the wind generator being characterized in that it also comprises at least one system of centrifugal flyweights arranged in such a way as to re-duce the angle setting of at least a part of the blades when the speed of rotation tends to increase, at least one system of stops and means of return or compression which mechanically define the initial angle setting and the optimum operational angle set-ting up to the nominal speed, a part of the blades being mounted such that it pivots about an axis thus driving by the intermediary of at least one arm or lever or similar device, the end of at least one re-turn spring or of a compression spring, tending to maintain it in contact with at least one fixed stop defining the initial angle setting, the wind generator also being characterized in that in each pair of blades elements of one blade are connected to elements of the other blade.
