Getting closer to final product! Perfect fabrication on what is going to be a great turbine!!
sweet hinge bro! so much better than the old one. Nicely done!
Hey buddy ! great job on the proto-type. good idea on the rubber stops , if they start to break down you can replace them . i was thinking of a similar set up. the wider vain section will give the tail more support so it should furl without any flex in the tail. i was thinking of making a vain section that could adjust in or out once the tail is attached, so it could be easily adjusted to furl at different wind speeds. Looking forward to the finished proto-type. again, Great job on the fabrication!!!
You are a creative problem-solver.
thanks for sharing, next month i will start to build a similar "turbine" set up, but to be used in a river. Any suggestions since you already been using this turbine for a long time? THANKS!
If you're looking for an interesting design to use in a river, check out this video and his channel.ua-cam.com/video/0ieFZI4-6K8/v-deo.html
F&P motors are a good way to get started for cheap.
I been looking for them, but have not find them used, and buying it new defeats the purpose, also shipping to Chile would bring the cost up, but thanks, will keep on the lookout, thanks for your suggestion and for sharing your experience :)
thanks! i been on the lookout for one of those motors but haven't been lucky, I live close to Patagonia so it is a bit hard, thank you for taking the time to reply ;)
Cool ! But whats the purpose of the hinge? Has it something to do with gust ?
It's a furling mechanism. A compound angled hinge that causes the tail to lift when the wind reaches a certain speed (called the furling moment). As it does, it keeps tracking the wind but turns the rotor from facing the wind directly, which decreasing the swept area and subsequently the amount of wind force on the blades. When the wind speed drops below the furling moment, gravity pulls the tail back down and the rotor faces the wind again. Its purpose is to save the turbine from overspeed damage in high winds without having to stop the blades completely.
@@JamesBiggar Smart! Really enjoying the build proses ! Thanks for keeping us posted !
Hi James, how's your first axial flux wind turbine? Still running properly? You said, those magnets were cracking. Have you found out what caused that problem?
Hi. The turbine still works fine but I've taken it down a few weeks ago in preparation for the new turbine. It was the resin encapsulating the magnets that cracked, not the magnets - if they broke then I would have had to shut it down a long time ago. The problem was that I didn't use fiberglass in the resin, it's a must to withstand the temperature changes outdoors. I've since switched to using mag's that can be bolted to the rotor instead (they have to be manufactured with the bolt holes, they can't be drilled afterward). It's a much easier and cleaner method.
That's NICE! I need to build a 1.21 gigawatt turbine. I just need the copper and magnets!
1.21 gigawatts?!! Avoid shopping with Libyan terrorists lol
James Biggar yea no doubt! And electrical storms! Seriously though I'm thinking about 2000 watts, plus, it will basically only make power in storm season. When its cloudy and no sun. I only get 200- 400, watts when there is no sun, I guess I'd need it Strong enough to handle stormy wind. we get gust near 50 mph, and over. Great video..
Are you thinking of going "Back to the Future"?
Impressive construction! From the point-of-view of a complete outsider, the calculation of the furling moment and furling angle at the hinge, seems a very complex calculation, having in mind the number of forces, masses, surfaces and overall geometry involved - is there a practical way to calculate them, or you get there by trial and error? To me it seems something only possible to test and adjust in a wind tunnel.
Thanks! It's not as complicated as it seems. The hard work has already been done by researchers decades ago, they have it down to a science - no testing required unless a person strays from the theory. Hugh Piggot lays out a guideline in his 'recipe book', ie: a certain tail boom length/weight, vain surface area/weight, generator offset, hinge angle, etc., for a given swept area. All of those factors play a role, along with the wind. For example, my tail boom needs to be 60" long, the tail vain has to have a surface area of ~13 sq.ft, the generator needs to be offset by 8", the hinge angle from the vertical rotor plane is ~15°, the hinge angle from the horizontal rotor plane is ~40°, and the total weight of the tail should be around 25 lbs.
I personally use logging gear, but anyone with a decent anemometer that they can attach to their tower can determine the furling moment of their turbine and adjust the weight/length of the tail accordingly (if they're doing it the hard way and trying to figure it out on their own). Inspeed's Cateye works great. Wind tunnels are overrated to be honest. They're fine for loading up a new generator to verify performance and establish a power curve, or for analyzing the aerodynamics of a new rotor. But they generate almost perfectly clean wind in one direction (as in straight flowing, non-turbulent). If the wind only blows in one direction, then tracking isn't being tested and it's hard to fully understand how the furling mechanism will behave unless the tracking is being tested at the same time the rotor is being loaded up. In the real world, perfectly clean and consistent wind is hardly ever the case even on the tallest towers. There are sudden changes in wind direction, drag force, pressure and air density, turbulence, etc. Despite all of the wind testing that can be done, these need to be factored into the equation at the end of the day. There's just no substitute for the real world. With proper logging gear, the data collected from an actual installation site is just as if not more useful than what a wind tunnel will produce. The same goes for power output. There were (and to my knowledge still are) micro turbine companies selling turbines by touting watt/rpm power curve charts that they (claim to have) established in a wind tunnel. Pitches like "This LOW WIND turbine will produce a whopping 1500 watts at ____ rpm", neglecting to mention the TSR of the rotor attached to the turbine, the wind speed needed to reach said rpm, or giving a rough estimate of avg monthly kilowatt hour production from the turbine at a certain tower height in a given wind zone - which is pretty easy to figure out with a wind atlas and a calculator. Then after the turbine is installed, the owner is usually disappointed because it's not performing like they expected. They thought it was a 'low wind' turbine that should be putting out 1500 watts, but find that it takes a 50 mph wind just to see half of that. When a person can see the power data log from a turbine performing in a real wind environment with all of its surprises and intermittency, then they have a much better idea of what to expect from day to day compared to looking at a power curve chart.
@@JamesBiggar WOW! Thanks for the comprehensive reply. I understand what you say and totally agree. My mistrust in small commercial turbines and lack of confidence in most projects I've seen in YT, are the main reasons I'm still trying to work my way into wind power - I'm still not sure what I want to do to get there :-)
You're not the only one. 'Snake oil' salesmen in the micro wind industry are a large part of the reason why my channel exists. If you ever have any questions, feel free to ask. I'm not the leading expert in wind energy but I'll do my best to help.
@@JamesBiggar Thanks! That means a lot! And you sure look like an expert, from where I stand. I've learned more from a couple of replies from you, than I did viewing a lot of videos and reading random texts in the web. From your call on Hugh Piggot, I found his 2003 manual online, where he explains a lot about the construction of the wind generator. This is now mandatory reading and, maybe, it will finally launch me on the path to build one :-)
I'm sure geography might be a factor but, you would do a ton less grinding if you had shielding gas on your welder and mig wire. I can tell you care about craftsmanship and sign your name in your work. So it seems crazy for you to be welding with such a dirty process. Tig would be best but your current welder looks to have a mig nozzle.
Edit to add:
I like the lack of music. Keep the videos coming.
Hmm, I don't find the mig dirty. Seems to work fine for me but I'm not a welder anyway. That's why I'm using a no-gas mig with flux core wire (it does the same thing as gas, just easier to use and cheaper to set up). As long as the weld penetrates, that's all that matters to me. The grinding is necessary around the leaves, otherwise the welds will bind up - no matter how pretty they look. Ideally, these parts would be machined, not welded together. But this is a prototype ;)
@@JamesBiggar If you can afford the equipmet you would love mig over innershield "flux core". A cleaner weld means less grinding to meet the tolerance required and more time enjoying the work. Check out the channel weld.com if you haven't. Good teacher on the subject.
Okay... I kinda want the details for the music at the end.
