My VAWT Project, next phase

Post some pics, I'm sure you get plenty of help.
You show us yours, and we'll all help

Here are photos of the finished (just a little "tweeking," balancing, etc necessary yet) turbine. The unit can be broken down to three parts - verticle frame, drive shaft and generator, and turbine "wings" - each of which I can haul up on the roof myself.

I've also decided to use golf cart of similar vehicle electric batteries, and design the electrical accoutrements from marine components. Next comes the charge controller and the battery decks and enclosure. I'm shopping for an extension ladder, too.

Good looking stuff, nice workshop too.
look forward to seeing it all on the roof.

I can't quite tell do they pivot [self dumping] in the frames?

where's the generator?

now that all that's out of the way

ohh Shiny

The alternator is at the bottom of the center driveshaft (at the arrow). And yes, the blades are self-furling, a screen-door spring device I designed myself. If I've done the math correctly, the furling device will "govern" the rpm to 120-150. We have fierce winds here, and I don't want a runaway turbine to burn out the alternator.

Which brings up something I'm curious about: The blades of my turbine are four feet long, fifteen inches wide, with the pivot point of the furling device twelve inches from the rear edge of the blade. The wings weigh nine pounds (mass .28125) and I have added nine ounces of weight at the rear edge of each wing. Radius at the thick part of the winds is 3.5 inches.

Can anyone here tell me what the centripetal-centrifugal force (the force being opposed by my furling device's springs) will be at the rear edge of the wings?

Del's right

I would add

post your goals

Average, min & max consumption

How much torque does your turbine produce

Quantify what you have & what you want to do with it.

Re: My VAWT Project, next phase

Hmmm. Well, the turbine is completed. As I said elsewhere here, it consists of three blades, each four feet long and fifteen inches wide. I have it apart at the moment, in order to install an update of my furling device, and in order to put it up on the roof. I have to put it up on the roof all by myself, so it will go up in three stages (the pedestal base is already on the roof), 4X5 turbine holder and holder to pedestal connections first, then the generator, turbine shaft and fuling device, then the turbine blades. I'll be happy to take pictures as I do it all.

Design starting torque is 1.65 ft lbs 0-120 rpm (load inertia is 42.25 ft lbs, full stop to design rpm, turbine total weight being 26 lbs). I expect to generate about 65 Watts.

But I can't imagine how pictures of the charges controller and wiring would look or how they would help with my question. I'll use an isolator immediately at the generator, then a rectifier (or rectifiers - 50 amp or so) and shunt regulator upstream from the battery bank. The battery bank will be wired to an inverter/charger, which will be wired to the load center and main fusebox (at first, I'm just going to power outside lights, in order to experiment with and "tweek" the design).

Thanks for the interest, and as soon as I start on the thing today, and when I have it up on the roof, I'll take pictures.
