Drela AG14 Airfoil Micro Drone Propeller (37.01g thrust @ 3V)

thingiverse

The motor was designed after careful consideration of the **Drela AG14** airfoil coordinates. All experiments were conducted on the **Drone Propeller Thrust Testing Jig**, a cleverly designed tool that can be found online. The results are displayed below. It was printed at a leisurely pace, using a 0.2 extruder nozzle at 0.04 height per layer to achieve optimal precision. A precision instrument such as an **X-ACTO Knife** was used to clean the print with ease. Next, I moved on to finishing the part by carefully sanding it down using a fine-grit 400 grit sandpaper. Here are the measurements for the four selected voltage values (you can also view these in the images taken during the experiment): - **1.5V** => **12.34 grams** - **2V** => **23.45 grams** - **2.5V** => **29.47 grams** - **3V** => **37.01 grams** The included files contain all relevant pictures from the test, along with six txt files that contain airfoil coordinates, printable STL files, and SLDPRT files for those who want to make their own changes to the drone propeller. If you're planning to print this motor, it's recommended that you use a **8520 coreless motor**. Alternatively, you can modify the design using the SLDPRT extension files if you have the necessary skills and software. A note of importance: The airfoil was plotted using the matplotlib library in python.
