  • METHOD FOR CIRCULATION CONTROLLED VERTICAL AXIS AND TURBINES
    Publication number: 20120045329
    Abstract: A method of controlling a vertical axis wind turbines using circulation control is presented. The comprising monitoring environmental conditions and the vertical axis wind turbine to determine a current system state, and selectively blowing air through a blowing slot of a blade of the vertical axis wind turn based on the current system state to achieve a desired system state.

  • CIRCULATION CONTROLLED VERTICAL AXIS WIND TURBINE
    Publication number: 20120014792
    Abstract: A circulation controlled vertical axis wind turbine is presented. The circulation controlled vertical axis wind turbine comprise one or more airfoils in communication with the turbine via a rotatable support shaft and an airfoil support structure. The one or more airfoils have a blowing slot disposed near the trailing edge, and a controller and control means modulates a flow of air between the blowing slot and an internal cavity of the airfoil.

  • AIRFOIL FOR CIRCULATION CONTROLLED VERTICAL AXIS WIND TURBINES
    Publication number: 20120003090
    Abstract: A airfoil blade for vertical axis wind turbines is presented. The airfoil blade comprises an internal cavity, an upper blowing slot disposed on the airfoil blade, and a lower blowing slot on the airfoil blade, and further comprises a valve means for variably connecting the outside air to the internal cavity through the blowing slots to selectively produce a variable lift-drag condition of said airfoil blade.
