  • Coaxial wind turbine apparatus having a closeable air inlet opening
    Patent number: 6638005
    Abstract: A coaxial wind turbine apparatus which includes a pair of rearward-mounted, spring-loaded fins to orient the air inlet opening to face the direction of the oncoming wind and close a damper panel or shutter array at the air inlet opening during very high wind conditions. Thereby, the pair of rearward-mounted, spring-loaded fins stabilizes the apparatus during strong ambient wind conditions and minimizes damage to the rotating turbine wheel in the presence of a strong wind.
