  • INDEPENDENT VARIABLE BLADE PITCH AND GEOMETRY WIND TURBINE CONTROL
    Publication number: 20140322013
    Abstract: A variable blade pitch wind turbine and method of passively varying the blade pitch is presented. Each blade of the turbine rotor can individually and passively rotate about a respective blade axis to continuously vary the pitch of the blades to adjust to the ever changing wind speed and direction without active controls or other mechanical or electrical induced inputs to force rotational movement of the blades. Sections of each blade can respectively rotate to change the blade twist. In one example, a second rotor is used to improve the efficiency of the wind turbine and increase output of the electric generating equipment.
