About this model
This is an OpenSCAD module library for propellers and spinners. See this excellent video by Bruno Antunes on how to integrate this library into Fusion 360. This design models elliptical propeller blades that transition smoothly through three different NACA airfoils, starting with (by default) NACA 8430 at the hub radius, transitioning to NACA 6412 at 33% of the blade length, ending with NACA 3412 at the blade tip. The propeller design considerations are described in my blog article "Elliptical blade NACA airfoil propeller". Please refer to that if you need to understand NACA airfoil 4-digit codes. By default, this OpenSCAD script shows a collection of propellers. There are other demos available by ucommenting lines, including one that generates five random propellers and fans every time yo…
