Snoopy

[(unknown)]

Well there has been a lot of procrastinating since I bought the magnets three years ago but its going to fly Tomarrow we called it Snoopy because it resembles snoopys plane.It is a version of The 17' machine that dan built however my blades are only 14'6"x 2' at the widest point. all comments are welcome

My My ,  what a big wind turbine you have there.

How much power do you think you can get out of it ?

Does it have Furling ?

I know that you have been at it for a long time, I built my wind generator 5 years ago and I still haven't put it up yet.

Do I win the procrastination award . . .

cool...

no furling??

looks like a beast are right........

strange-snoopys christmas song just came on the radio as i was reading your post!!

strange but true........................

Hi Woofy you win .no furling what I am planning to do is some sort of RPM activated switch that shorts the three phases through heating elements in different stages .I have a small wind generator that does that and seems to work well I was hoping to get robert from Design Specialties  to help me but have been able to get a hold of him yet.If anyone knows of someone that this has worked for let me know.with any luck I should get 3-4 KW out of snoopy thanks for the comment

Nice looking machine indeed.

Because your turbine has a shaft for the generator and rotor, it would be fairly easy to add a mechanical brake for backup, just in case the stall control proves to be inadequate.

Great Job

I would like to see more pics on those blades, during construction. The pics make it look like it was mostly built with aluminum, is that so. Do you have the tower ready. Where will it fly.

That sure looks like an awesome turbine, did you make the blades? At first glance the mainshaft seems quite small for the huge gyroscopic forces it will see as the machine yaws. Also it appears in the pictures that those keyways in the hallow shaft are cut all the way into the center, doing so greatly reduces the strength of the shaft. I would seriously consider adding a third pillow block near the front magnet rotor to at least support that long length of unsupported shaft at the alternator, that will at least eliminate the shaft deflection that will cause the magnet rotors to rub the stator during yaw.

Hello...

I like it!

looks beefy enough to me.  

Perhaps add an oil seal to the bearing..(second pic)

and some jam nuts on the bolts holding the rotor to the shaft?

I think your prop is going to "sing"

I see that, too. Lawnmowers uses aluminum shear keys on the flywheel. Maybe pot metal keys instead of steel would work as a fail-safe. It would have been better to key the disc assembly so if something seized in a gale, the blade assembly would just slip/shear and not self-destruct.
