Drela AG19 Airfoil Micro Drone Propeller (32.12g thrust @ 3V)

thingiverse

I successfully designed the micro drone propeller by utilizing the Drela AG19 airfoil coordinates. Tests were conducted on the Micro Drone Propeller Thrust Testing Jig (results below). I printed this part with a slow setting, employing a 0.2 nozzle at 0.04mm layer height. I cleaned the final part using a Precision Knife. After that, I proceeded to finish the propeller with a small piece of 400 grit sandpaper. These are the thrust readings for a few voltage presets (you can also check these out in the images): - 1.5V => 9.47 grams - 2V => 19.05 grams - 2.5V => 26.47 grams - 3V => 32.12 grams The files you can download include all pictures relevant to the test, along with six txt files that contain airfoil coordinates, the STL files and finally the SLDPRT files. To use the propeller, you should get an 8520 coreless motor. You should use the SLDPRT files if you wish to adapt the propeller model to suit your own needs. Note: The airfoil plotted using the matplotlib library in Python was used to create this design.
