8x3.8 Propeller

This 8x3.8 propeller is suitable for airplane and multicopter designs. I developed it using prop geometry from http://www.ae.illinois.edu/m-selig/props/propDB.html and airfoil geometry from http://airfoiltools.com/airfoil/details?airfoil=naca4412-il to create 2D slices. The Solidworks program was then used to combine these slices into a propeller. The NACA0012 airfoil, chord length, and blade angles are accurate; however, the positioning of each slice is estimated using two piecewise functions. To simplify 3D printing, this propeller has been thickened compared to my other designs.
