Small wind turbine - U2

thingiverse

I built a replica of an Ugrinsky rotor for my balcony. First, I experimented with different variations to see how well the design worked. Once I saw its effectiveness, I decided to build my own rotor. The specs are impressive - it's 160 mm in diameter and 200 mm high. It had to be two-colored so that you could tell the wind speed from a distance, even if you weren't right next to it. And of course, it should generate electricity! The rotor design is stackable, meaning I can add as many wings on top of each other as I like. At some point, however, I'll need to install a mounting system at the top end of the axle. After building and printing two wing segments stacked on top of each other, everything turned out perfectly fine. After six months of successful operation, I realized that you can't tell which direction the wind is coming from - only how strong it is. That's why I added a plastic flag made of not-so-elegant material, but it's two-colored! Now I can see exactly where the wind is coming from! Unfortunately, there's no point in generating electricity here in the city because the rotor is too small and the wind is too weak. Maybe you live somewhere with more wind - like the North Atlantic? To print out the necessary parts, you'll need a 6 mm thick aluminum rod, two ball bearings measuring 6mm x 13 x 5mm, a thin belt, a small motor, thin wire (if you want electricity), and a base plate where you can place stones to keep everything from flying away. You can find the SW 2017 files with the same name on grabca*. Have fun generating lots of electricity! Best regards, Antonin T. Clark / March 20, 2020
