Abstract
The method of fairing the blades of a wind turbine in which the angle of the blades is sensitive to the wind speed, providing blades which are pivotably mounted on a blade mounting about a blade axis generally perpendicular to the axis of wind turbine rotation, providing the blades have more wind surface area facing the wind on one side of the blade axis than the other side of the blade axis giving a torsion on the blades about the blade axis due to wind load, providing a moment arm mounted on each of the blades which translates the torsion into force proximately parallel to the axis of wind turbine rotation, providing a reaction plate to receive the force generated by the torsion, supporting the reaction plate by springs such that increasing wind load will move the reaction plate and change the angle of the blades.
