| 20110020123 | Wind Turbine with Adjustable Airfoils - The present invention concerns a wind turbine having a plurality of vertically extending airfoils forming a rotating carousel rotating about a central axis thereof. The airfoils pivot about their leading edges to adjust the pitch angle thereof to maximize energy harvest when the airfoils are rotating both in an upwind direction and in a down wind direction. This pivoting movement results from trailing edges of the airfoils being pivotally secured to rigid spokes or cables of a trailing edge hub. An adjustment mechanism is pivotally mounted between a carousel hub and the trailing edge hub and is used to control the separation between a central axis of the trailing edge hub and the axis of rotation of the carousel as they co-rotate. As the carousel rotates, the offset distance between the two axes determines the maximum achievable pitch angle of each airfoil. The airfoils then continually cycle between a positive and negative value of the maximum pitch angle so that each airfoil is at its most desirable pitch angle relative to its position around the carousel and relative to the existing wind direction in order to create maximum lift. A wind direction rudder is secured to the adjustment mechanism to provide for movement thereof resulting in movement of the trailing edge hub as wind direction changes so that the most desirable pitch angle of the airfoils relative to wind direction is maintained. | 01-27-2011 |
