12 foot 12 volt help

[BuddyL]

Ill hope to get enough info that this can be helpfull. This is going to be a 12 ft. rotor already built. It is made of white pine 2 1/4 thick 7in. wide 6 feet long. So the root of the blade is 7 inches wide pitch 20 deg. it tapers down to 3 1/2 at the end and about 10deg.  about 15 in the center. the overall weight of each blade is 6 pounds. This will be a dual magnet rotor 12 each 1-2-1/2 magnets like is used on many others.The wire is #13gauge and will be 9 coils . The disks will be 11-12 inches looks like it will fit ok. I want this to work in low wind as well as possible. So how many turns on each coil 30-45 is my best guess. Most all 12 volt are 10 footer not 12 So with out help iam lost. I sure could help with cutin speed and number of turns TSR and any other good advice!

You should have asked for help before you made the rotor. 10 deg at the tip is good for about tsr3 but the width is all wrong.  Firewood I suspect.

Been thinking about this. If you have glued the blades to the hub I don't know what you can do, but if you have screw them and can dismantle the hub, then you can plane the root of the blades at an angle of about 7 deg to reduce the angle at the tip to about 3 deg. You will have to do both sides to keep things parallel.

If you can sort out the prop then it is worth thinking about the alternator but you need to know tsr before you can do much with that.
