Abstract:
1. A wind turbine comprising: a rotor including a rotatable hub and a plurality of rotor blades, each of the plurality of rotor blades being attached to the hub; and at least one airfoil body including an aerodynamic profile and an airfoil body root portion; wherein said aerodynamic profile is configured for increasing aerodynamic lift of at least an inner portion of a rotor blade; wherein said at least one airfoil body is attached to said hub at said airfoil body root portion, and wherein said at least one airfoil body is attached to said hub in a manner such that a relative position between said at least one airfoil body and said plurality of rotor blades is fixable during a rotation of said rotor, and said relative position is adjustable for regulating the increase of aerodynamic lift of at least the inner portion of the rotor blade.
