Beware my friend, it's a loooong and detailed instructable since professional wind turbine have many parameters to take in account.
After that we'll jump, and backflip like ninjas with file formats to land in 123D Make and finally build this blade.
With all this you're (almost) ready to start manufacturing wind turbines :)
My goal is to show that a high tech industrial product can be made with a few tools, limited material and some knowledge (tricks?) and I hope to physically help make this kind of development in some parts of the world where you can't afford to buy such high end products but need them to generate green energy for local community development.
If you find this project green, worth a laser cutter, simply useful or beautiful, please vote for it by clicking on the "vote" button at the upper right corner of this page. It's really appreciated.
Materials needed:
Cardboard (or MDF) of the same thickness and in good condition (not pressed or compressed) 594x840mm minimum.
A wood stick of section 30x30mm and 600mm long minimum.
Laser cutter or brand new scalpel or knife, to cut properly and without compressing cardboard (or scroll saw for MDF).
Laser cutter or table saw for cutting wood stick (or jigsaw).
Non permanent spray adhesive (in DIY store).
Fiberglass: Roving 500g / m² and 200g / m², with carbon fiber if possible, or designed for wind turbines ideally
Epoxy Resin (laminating epoxy to prevent vapors from polyester and to master drying).
Printer and paper (or layer).
Calipers (just to measure some thickness).
If using a scalpel, a cutting mat to make precise and clean cut.
