Drela AG16 Airfoil Micro Drone Propeller (35.20g thrust @ 3V)

thingiverse

This propeller has been engineered from scratch using **Drela AG16** airfoil coordinates as a benchmark. All experiments were conducted using the versatile **Drone Propeller Thrust Testing Jig**, which can be found on Thingiverse at [http://www.thingiverse.com/thing:2302071](http://www.thingiverse.com/thing:2302071). Detailed results are listed below. The part was printed with deliberate slowness, employing a **0.2 extruder nozzle** at 0.04mm layer height for optimal quality. Subsequent cleaning involved the use of an **X-ACTO Knife**, available on Amazon at [http://amzn.to/2pV1sGA](http://amzn.to/2pV1sGA). Following this, I proceeded to sand it using a high-grit **400 grit sandpaper** accessible on Amazon at [http://amzn.to/2pTNwic](http://amzn.to/2pTNwic). Below are the readings for various voltage settings (also visible in accompanying images): - **1.5V** yields a thrust of **12.53 grams** - **2V** generates a thrust of **22.05 grams** - **2.5V** produces a thrust of **28.44 grams** - **3V** achieves a thrust of **35.2 grams** The downloadable files contain all relevant images, along with six text files featuring the airfoil coordinates used in construction, printable STL files, and SLDPRT files for customization. If you decide to use this propeller, ensure that you have an ample supply of **8520 coreless motors**, available on Amazon at [http://amzn.to/2qPUhi4](http://amzn.to/2qPUhi4). For users who wish to modify the drone propeller, we recommend using the SLDPRT files for a seamless experience. The airfoil was plotted using matplotlib, a powerful python library.
