Abstract
A wind turbine includes a nacelle mounted atop a tower. Power generating components are housed within the nacelle. A rotor hub is rotationally coupled to the power generating components. A plurality of blades are fixed to the rotor hub. The blades include a root section extending radially outward from the rotor hub and an aerodynamic section extending radially outward from the root section, wherein lift is generated by the blades primarily along the aerodynamic section. Aerodynamic fins extend radially outward from the rotor hub alongside the root sections of the blades and have an aerodynamic shape so as to capture wind and impart rotational torque to the hub from a central impinging wind zone that is coaxial to the rotor hub and the blade root sections.
