MATLAB: How to design blades in Matlab

propeller

I'm trying to design propeller blades like in the attached photo but I'm not sure where to start, any suggestions?

Best Answer

Only the blades are going to be a problem, since the rest of the shapes appear to be straightforward. See: how to convert 2D graph to 3D? (link) for a way to draw them as 3D shapes. (This plotted a NACA wing section.) They are essentially plotted similarly to the cylinder function, although using a specific shape rather than a circle.
