This invention relates to a fixed geometry self starting wind turbine having a blade rotatable about a vertical axis. The blade is of a wide streamlined cambered airfoil shape and has a forward portion that includes a well rounded leading edge and thickness distribution that is conducive to high lift to drag ratios and having a high drag characteristic in reversed flows. The concave curvature of this camber line of said airfoil is directed to the rotational axis. The wide blade in combination with the well rounded leading edge, camber and airfoil thickne...
In a fixed geometry wind turbine: a blade, said blade comprising a fixed geometry upwardly extending elongated element which is relatively long as compared to its width and thickness, said blade being mounted for rotation about a vertical axis, said blade having two sides, the first of which faces said axis and the second of which, faces away from said axis, the improvement comprising: said blade having a representative cross-section in a plane transverse to said axis, that includes a cambered profile, the median of said blade cross-section profile being...
