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.
Claims19
A coaxial wind turbine apparatus comprising:
- a rotatable turbine housing having an air inlet opening and an air outlet opening;
- a rotatable turbine wheel housed in said turbine housing between the air inlet opening and the air outlet opening;
- a damper panel array coupled to the air inlet opening;
- and,
- a pair of spring-loaded fins mounted at a rear of said turbine housing and linked to the damper panel array wherein the pair of spring-loaded fins orients the air inlet opening to face oncoming wind and closes the damper panel array during strong ambient wind conditions.
2 more elements
A coaxial wind turbine apparatus comprising:
- means for housing a wind turbine having means for receiving oncoming wind and means for exiting wind;
- means for closing the wind receiving means;
- and,
- means for stabilizing the housing means, orienting said wind receiving means to face the oncoming wind and closing the wind receiving closing means during strong ambient wind conditions, said stabilizing, orienting and closing means including a pair of spring-loaded fins spring biased to maintain the wind receiving closing means open during normal ambient wind conditions.
1 more element
A method creating wind turbine energy comprising the-steps of:
- rotating a wind inlet opening of a wind turbine in a direction of oncoming ambient wind;
- detecting a strong oncoming ambient wind with pair of spring-loaded fins;
- closing said wind inlet when said strong oncoming ambient wind is detected.
