ABSTRACT:
A vertical axis wind turbine is provided based on my co-pending application Ser. No. 890,998, filed Mar. 28, 1978, now U.S. Pat. No. 4,204,805. In this improved system the centrifugal forces of rotation produce no bending moments in the air foil spars. Also, the center of mass, the center of useful aerodynamic pressure and the center of main bearing supported are located at the same point to the support structure.
