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

thingiverse

I managed to design the micro drone propeller by using the **Drela AG19** airfoil coordinates. Tests were performed on the **[Micro Drone Propeller Thrust Testing Jig](http://www.thingiverse.com/thing:2302071)** (results below). I printed this part with a slow setting, with the help of a **[0.2 nozzle](http://amzn.to/2qQdFvg)** at 0.04mm layer height. I cleaned the final part using a **[Precision Knife](http://amzn.to/2pV1sGA)** After this, I then got to finish the propeller with a small piece of **[400 grit sandpaper](http://amzn.to/2pTNwic)**. 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 consist of all pictures relevant to the test, along with 6 txt files that contain airfoil coordinates, the STL files and finally the SLDPRT files. Should you like to use the propeller, you should get a **[8520 coreless motor](http://amzn.to/2qPUhi4)**. You should use the SLDPRT files, should you wish to adapt the propeller model to suit your own needs. **Note:** The airfoil plotted by using the matplotlib library in python.
