An important component of WinDIY are certainly the wings. They absorb the energy of the wind and convert it into a rotary motion, which in turn feeds the generator and thus produces energy. <\/p>\n\n\n\n

Of course, the wings should be as light as possible. At the same time, however, stable enough to withstand the forces even in stronger winds.<\/p>\n\n\n\n

On the way to a suitable design I have therefore experimented a bit. Info about these experiments can be found here: https:\/\/hackaday.io\/project\/172328-windiy-hawt-wind-turbine\/log\/179141-windy-wing-mark-3-a-modular-easy-replaceable-and-scalable-blade<\/a><\/em><\/strong><\/p>\n\n\n\n

In the following article you will find the tips to rebuild the wing. You will need three copies of this wing (of course).<\/p>\n\n\n\n

Important: The wind turbine is currently (11.10.2020) not yet running perfectly. The blades still need to be adjusted and also the generator does not quite fit the characteristics of the wind turbine. So there is still some work ahead of me. But maybe the shown components are a suggestion for everyone who is working on his own design of a 3D printed wind turbine \ud83d\ude42 .<\/p>\n\n\n\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>

Wing profile info<\/h2>\n\n\n\n

The design of the wing is based on the NACA4412 profile with a chord length of 120mm.<\/p>\n\n\n\n

On the following page you will find info and configurable templates for this and other wing profiles: http:\/\/airfoiltools.com\/airfoil\/details?airfoil=naca4412-il<\/a><\/em><\/strong><\/p>\n\n\n\n

Collect required parts<\/h2>\n\n\n\n

Before you can start building the wing, you must of course have all the necessary parts together. A complete list of the required materials and tools can be found above in the material and tool list. <\/p>\n\n\n\n

The plastic parts can be easily created with a 3D printer. All parts are designed so that they can be printed on a normal FMD printer.<\/p>\n<\/div><\/div>\n\n\n\n

The required STL files for printing can be found here: https:\/\/github.com\/Nerdiyde\/WinDIY\/tree\/master\/wingMk3<\/a><\/em><\/strong><\/p>\n\n\n\n

I printed the parts with the following settings. <\/p>\n\n\n\n
