In 2020 I presented a wind turbine called "WinDIY", which can be largely made from 3D printable parts. (You can find information on this here: https://nerdiy.de/en/windiy-die-wind-turbine-aus-dem-3d-drucker/ and here: https://hackaday.io/project/172328-windiy-hawt-wind-turbine)
Quickly after building the first prototype, it became clear that I would like to build a new (completely redisgned) version. The construction of the first version of WinDIY worked in principle, but there was a lot of room for optimization.
- The mechanical brake is not really needed. To keep it simple I removed it from the design
- The whole construction was difficult to build
- No waterproof housing available
- Mechanical pitch control not reliable on long term
- Gondola and windvane use a lot of space
- Blades not tapered or optimized for the turbine and also difficult to build
- Integrated generator has small power
- Complicated wiring of the electronics
I want to implement these optimizations with a completely new design. For this, not only the design of the blades is being reworked. Also the 3D printed generator will be completely redesigned. In addition, I will also try to simplify the somewhat complex mechanics. Ultimately, the structure should be lighter, the turbine should run more efficiently and also be a little more compact.
I'm currently working on the first basics such as the newly designed pitch actuator and the generator. You can see the first progress in the project logs. :)
