A wind turbine having a wing rotor with two rotor blades supported on a hub; to accommodate different wind velocities nearer and further from the ground and to accommodate the components of wind force transverse to the rotor blade plane of rotation, the pitch of the blade that is then higher above the ground is altered with respect to the pitch of the blade that is nearer to the ground; this can be done by appropriate swivel mounting of the rotor hub for allowing its reorientation to change the effective pitch of the blades as they rotate high and low; or it can be done by a blade swiveling means sensitive to wind conditions.

A wind turbine, including an axial flow through wing rotor; said rotor comprising a rotor hub and at least one wing blade having a pitch with respect to the wind flow so as to be adapted to rotate with said hub in the wind flow, said wing blade being supported by said hub and projecting therefrom; a rotor shaft; said hub being supported on said rotor shaft and being connected thereto such that rotation of said rotor rotates said rotor shaft; a bearing seat for carrying said rotor shaft for rotation in said bearing seat; said seat being rotatable around an axis which extends substantially vertically for turning said rotor into the wind; each said wing blade being inclined relative to the general plane of rotation of said rotor; means for enabling said rotor, which is comprised of said hub and said wing blade, to deflect under the effect of a transverse force acting on said rotor across the wind direction, which transverse force is the resultant of various wind velocities at various regions of the plane of revolution of said rotor, and said deflection of said rotor initiating a reduction of the transverse force acting on said rotor.
