Abstract
Methods, systems, and devices for dynamic wind turbine rotational speed control are described. The method may include attaching a vane shaft to a support arm of the wind turbine, the vane shaft partially inserted into a cylindrical aperture of an airfoil of the wind turbine, rotating an airfoil around a vertical axis of the wind turbine, and controlling, via a torsion spring of the wind turbine, when a rear stop of the speed control assembly exerts a force on the airfoil to reduce the rotational speed of the wind turbine, where the torsion spring is configured to facilitate the rear stop to exert the force on the airfoil when a rotational speed of the wind turbine around the vertical axis exceeds a set rotational speed, where a portion of the vane shaft is inserted into a helical portion of the torsion spring.
