ABSTRACT:
An offset-axis type wind generator uses a passive cyclic pitch-change rotor whose shaft axis is inclined downward and aft, with its sense of rotation selected so that the yaw component of the shaft torque at least partially of the shaft torque offsets that component of thrust which accompanies power extraction. A wind-alignment vane extends from a boom mounted on a furling hinge, equipped with mechanism to limit the vane's anti-furling moment to balance only the remainder of the moment of rotor thrust. Hence, disengagement of power extraction does not cause the rotor to overspeed, and the machine may idle even in gale-force winds, furled to nearly 90.degree..
