tork blade up and flying
By hiker, Section Wind Posted on Thu Jul 15th, 2004 at 01:27:30 AM MST
its a keeper

for a simple blade i was surprized at its output--it maxed out my little 1/4 hp
motor to alt. conversion--acted like it wasnt even there' even when i loaded up the alt..next i will install my 3/4 hp motor to alt conversion.should crank right up..
the gear ratio is about 3 to 1..handles good in a light breeze or strong wind..
dosent seem to really over speed in a high wind--but starts easy in a light one..
the prop stands about six feet high--somewhat over kill for my little 1/4hp. alt.
should match up with the higher output 3/4 hp. alt.--it has ceramics and neos for
more amps and volts--well thats another story..later. ;]

I hope you don't drive that way!!! :-)

Congratulations on your succesful turbine. May the wind blow onto your blades long and strong.

Well I am absolulty surprised that those blades worked!! Congradulations!
So whats up with the mix of neos and ceramics?? Wana hear more on that one.. surprise me again!

>> all energy used to produce this comment or post came from solar and wind energy! It works!

hello ifred

its just my old 3/4hp maytag motor --i put neo mags on top of the ceramics to close the airgap--i only made this blade as a test-because i geared up my alt. and needed
some tork to get it going--it may not turn as fast as my single high speed blades
but thats where the gears come in to play.....

Looks good hiker!
I like the simplistic blades. I have been thinking about making a set of blades for my pm motors but was overwhelmed with the technical aspect of airfoil design. This looks like something I can handle. Care to share the dimensions?

Thanks

If your blades only get a quarter the efficiency of an optimized design, just make the rotor twice the diameter and use stronger guy wires. B-) Airfoil curves are good, but hardly necessary.

bonz

not a whole lot to it--three 3/4" plywood disks glued togeather --two fence boards
cut in half--cut 4 angled slots in the disk--slide your boards in and hold them in place with glue and screws-- i used a belt sander on mine to feather out the ends of
the blades and to round off the leading edge--then just throw on some stain or paint.

I guess the only thing that isn't self evident is the pitch. I saw on your first post that you might have to change it. Looks to be a 45 cut, would you go more or less?

A tyro sez thanks
