Designing the Windmill Blades
The purpose of the blade design is to trap the wind's energy inside, so there is 4 main things that we need to have perfect on our windmill. The four main ideas involve the blades in how the: Pitch, shape, length, and quantity are all precise. First, is the pitch, the pitch is how you have the windmill blades angled so the wind can capture it perfectly. Our windmill has 3 blades that are all angled the same direction. The second thing on the list is the shape. Right now are windmill blades are rectangles rounded at one end and pitched at a left angled direction. Thirdly, there is the lentgh, the length is how long the blade will be on our windmills. We learned that 8 inch blades work the best, so that is what we will use. We tried our Windmill out with 8 blades and it worked perfectly. Lastly, we have the quantity of the blades. Our team has 3 blades because it works better than the rest. We tried 2 and it worked well, but once we tried 3 it seemed to spin faster and more accurate. Our team is doing wonderful and can't wait to finish!
