I am looking for good blades to use with a large swept area
anyone have good suggestions
This guy knows his stuff, he has been designing and building Wind Turbines the last 40 years.
He does several size's and length of blades.
He even shows you how to carve blades to the ideal shape and form.

Everything is possible, just give me Time.
The OzInverter man. Normandy France.
3off Hugh P's 3.7m dia wind turbines, (11 years running). ... 5kW PV on 3 Trackers, (6 years) .... 9kW PV AC coupled using Used/second hand GTI's, on my OzInverter created Grid, and back charging with the AC Coupling and OzInverter to my 48v 1300ah batteries.
My humble understanding is that fewer blades offer superior efficiency of some type. I'm sure that subject gets complicated of course.
Fewer blades get "clean" air for each blade.
More blades loose efficiency at lower speeds then few blade turbines
Not much information to make any suggestions. Specific generator, RPM, windspeed range, power output?
There are a bunch of links if you search 'custom wind generator blades'. You might also get some ideas from the blade calculator at https://www.warlock.com.au/mobile/tools/bladecalc.htm.
Are you wanting to make your own? A die and a press could make good aluminum blades in 1/2 second. Of course home made is always more satisfying.
Just go ahead and make yourself a set like these!!
thank you...I may just build that whole thing.....but I need to make mine for 48 volts
If I am not mistaken his stator can do over 48V also. He system is currently setup for 24V but he is switching over to 48V. He has the plans for sale for the whole turbine. I think he went with the dual stator setup just for fun and to do something "fancy" for youtube. I am getting a single stator axial built right now.
