Need a new tail

Postby dgassett on Thu Jan 27, 2011 4:35 pm

Is there a tail design for a 1 KW wind turbine that will keep the turbine in the wind? We have a lot of wind turbulence that keep the turbine from staying directly in the wind.The tail seems to over compensate back and forth 20 to 30 degrees just enough to slow the blades. Help! Thanks, Doug

G’day
I too have a lot of turbulence and need to correct it to start generating any sort of reliable power. I basically get nothing from the turbine as it rotates/wobbles just as you say. I have concluded from research, in my installation anyway, the only answer is to increase the height of the tower, way above the trees that are creating it. So I’m in the process of going from 13metres to 20.
Don’t know if this is of any help.
Regards
Jamie.

What about adding some friction to the pivot to dampen the motion?

I like your thinking.
The trick would be to dampen it enough to stop the wobbling but not too much to stop it staying in the wind.

The other thing to keep in mind is that turbulence decreases the turbine efficiency, even if the turbulence created rotation (wobbling) was dampened, moving above the turbulence would result in increased power generation.
I’m committed to my new tower and need every watt I can get.

I think I found a way. On the Windmax there is a pivot point that the turbine swivels on. I took a piece of nylon rope and wrapped it one complete turn around the swivel and attached both ends of the rope to a spring attached to the tail of the turbine. I adjusted the ropes tenson with the spring. It took a few tries in the wind to get it right and it works. The nylon rope holds up in the sun and weather. It finally worked for me. Thanks Doug
