Hello! I have been tasked with designing and modeling a blade for a desk fan. The only set parameters are a 200cfm output and a 140mm outer diameter powered by a 12v motor to be sourced by me. Although I am a professional CAD guy, this will be my first time working on a project like this. Could you give me some pointers on where to start? Are there tables to look up blade angle, surface, etc? Thanks!
