A wind turbine operated electrical generator system, said system comprising a wind turbine of the axial flow type, the blades of the turbine including tip portions pivoted with respect to the remainder of the blade, a generator driven by the wind turbine and designed to operate within a given rotational speed range, said speed range being below the speed at which the wind turbine can develop its maximum power, a pin and socket connection on the outer end of at least some of said blades, and preferably each blade, for connecting the tip thereto and a cam track on the pin or socket, with a follower on the socket or pin, respectively, the cam track being shaped to cause the tip to pivot under centrifugal movement of the tip, so that a change in the torque produced by the pivoting at all times maintains the speed substantially within said given range, resilient means being provided to restore the position of the or each tip against centrifugal action.

In a wind turbine operated electrical generator system, said system comprising a wind turbine of the axial flow type, blades of the turbine, tip portions of said blades each pivoted with respect to the remainder of the blade, a generator driven by the wind turbine and designed to operate within a given rotational speed range, said speed range being below the speed at which the wind turbine can develop its maximum power, a pin and socket connection on the outer end of at least some of said blades, for connecting the tip portion thereto, a cam track on the pin or socket, a cam follower on the socket or pin, respectively, and engaging in said cam track, the cam track being shaped to cause the tip to pivot under centrifugal movement of the tip, and resilient means to restore the position of said at least one tip against centrifugal action, the improvement consisting in that the characteristics of the resilient means and the cam track shape are designed to operate entirely within the upper portion of said speed range, to cause said system to operate always below the speed at which the turbine can produce its maximum power, to ensure that a change in the torque produced by pivoting of the tip, caused by centrifugal movement thereof causes a continuous fluctuation in the speed which is within said upper portion of the given range, thereby positively to control the power output of the system and in that means associated with said generator for accommodating said speed fluctuation.
