Abstract
A wind turbine having blades that rotate in a horizontal plane about a vertical axis. A single output shaft is directly connected by one-way bearings to the driven shaft of a permanent magnet generator. This eliminates the need for a gearbox and also eliminates the need for inverters. Friction losses are further reduced by suspending the vertical shaft with magnetic bearings. Airfoils are positioned in a specific vertical design so that they cup the wind on a lower concave portion of the airfoil for self-starting capability. Stealth radar-absorbing mesh and faceted mounting structures reduce scrambling of radar returns.
