Abstract

See full text

A wind turbine rotor blade assembly which incorporates automatic-aerodynamic control of the blade pitch angle is disclosed. The airfoil of the rotor blade (110) is free to rotate about a strategically located longitudinal blade axis which forms the spar stub (115) and is connected to the hub (120) of a horizontal axis wind turbine. The location of this blade axis is precisely set with respect to the turbine blade's aerodynamic center and center of mass. By further incorporating a reflexed airfoil with positive pitching moment this arrangement aerodynamically induces an automatic and self-regulating alignment of the rotor blade pitch such that the airfoil is always operating at or near optimal angle of attack. Details are disclosed on these strategic relationships which enable the successful operation of the new blade design.
