How to Build a Wind Turbine as a School Project. Horizontal axis wind turbine. One end of the blade is broad while the other end is narrow. And make a template. Explore wind turbine processes with blade ranging from balsa wood, aluminum cans, plastic water bottles, cardboard, etc. Students make blades out of Styrofoam bowls, pie pans, paper, aluminum. Illustration How to make windmill blades from cardboard. Wind Turbines Made Out of Paper. How To Make A Rubber Band Car. Preschool Kite Craft Template. This was designed by me, a real Aerospace Engineer, using real airfoils, and optimized for a small wind turbine at lower starting wind speeds. I promise you it is easier then you think. I will even provide you with a pdf drawing that you can print out, and use as a template. So I want everyone to start making wind turbine blades. The straw acts as a shaft to mount your paper wind turbine onto the tower. Now you can pin your blades to the end of the wood but don`t push them in so tight that they can`t spin. Tape the skewer to the dowel or other piece of wood to make the tower, making it extend more than half the length of the straw shaft.

Wind Turbine Blade Repair
Basically , all I do is place my template at each section, which I marked from the previous step, all around the blade. I align each template on the front side (leading) edge and mark the airfoil shape as it would touch that blade station. See below, C is marked at C, and D is marked at D. Where the most forward edge touches the line is the leading edge. I do this for every section along the blade. I then draw a line from peak to peak. This line is the leading edge line. And will guide you where NOT to cut. I repeat this is the line in which you do NOT want to remove material. You want to remove material above and below it, but that line is suppose to be the most forward part of the blade, and will never be cut. Make sense? I hope so, or your in trouble. I repeat this with the back edge (trailing edge).
FYI, leading and trailing edge is an Aerodynamics term, which as you may have guessed, is how the airfoil 'sees' the air. Leading edge being the first part of the airfoil or wing to feel the air, and the trailing edge is the last. See being a nerd is cool.
