tail design

what are the considerations for design of the tail?

Mine was 2ft by 2 ft and seemed to work well and put it at least half the blade diameter behind it.
I like my Vee tail better. It seems to turn into the wind when you can hardly feel it. But also waiting on better wind to see how it furls.

each side 2by 2 and what angle between them? i like the idea of the v, have seen power lines with a v shape humg on them.i heard that it cuts down on the whipping

About 30 Degrees.
I flared out the ends like in the picture.

But had to straighten them out because it would have hit my blades during furling.
I get turbulence here. The old flat tail used to turn out of the wind with the gusts and until it got to around 4-5 mph it would not re-orient into the wind. So every time the wind shifted the blades would stop. :cry: Now it slows a little but keeps on going.

http://www.thebackshed.com/Windmill/Docs/Furling.asp a site that has the formulas for a furling tail. has anyone used the design?

I tried using the formula.
I thought it would be too heavy for mine. Right now it is about 15lbs out 3 ft at a 20degree angle at the plate.
Waiting as usual for some wind to see when it furls.It is a little lighter than before but have no idea what effect the V tail will have on furling. :geek:
Will have to post a note when I have more wind here.

Look here for some info.
Better to be too light and furl early. Then add weight.

i like the idea of a v tail, to keep it from hunting and floping back and forth.

Alot of that floping back and forth is from to light of a unit not always from the tail design. But the more rudder you have in the lake of wind the more it will steer straight... :mrgreen:

was watching tv of a inflight refueling, the tanker boom has a v stabilizer. seems the way to go for the tail of a windgenerator.

I think those were for stabilizing and offsetting of some of the weight of the boom while in flight.

little wings to provide some lift? ithink you are right.also if that boom is floping around it would never get connected. i beleive there is a crew member in the tanker that can steer it by turning those tabs.

--Will have to make changes to the tail. Taking it down to about 25 degrees between panels and try again in a few weeks when I reinforce the pivot. It does not furl alot.
--The tail assembly is egging out the bushings. Will have to go to a bushing that goes all the way thru not just on the ends.
