Hey all. I'd like to build a small windmill in my backyard. Small is I'm going to guess maybe 5 foot blades or so. I do CAD work so I can design most of the parts I need EXCEPT the blades. I have no idea where to start. I understand the basic shape, but I'm unclear where to start to get one going in the size range I need. Does anyone know of any good resources to get me going? Book, website or something? I don't have a CFD program, but would like to take a stab at the design so I can make it myself. Any advice is appreciated. Thanks!
