A wind turbine is disclosed comprising blade forms mounted for limited pivotal movement as they proceed around an orbital path. A torque sensitive control means is provided to progressively limit the pivotal movement of the blade forms in response to changes in the rotational speed of the turbine so that high torque and efficiency is obtained throughout the operational range of the turbine.

A wind turbine for obtaining power from a wind flow comprising; a support structure; a rotor; means for mounting said rotor for rotation on said support structure about an axis of rotation; at least one blade form pivotally mounted on said rotor a distance from said axis of rotation for limited pivotal movement relative to said rotor, said blade form pivotally moving relative to said rotor in response to the force of a wind current against its sides to generate a rotational force for self-starting of said turbine and operation at low rotational speeds; and means for controlling said pivotal movement of said blade form relative to said rotor, said means progressively biasing said blade form toward one selected orientation relative to said rotor and thereby progressively limiting said pivotal movement of said blade form in response to increased rotational velocity of said rotor, said control means prohibiting said pivotal movement of said blade form at high rotational speeds of said turbine in a constant wind flow velocity.
