Boeing KC-135 Winglet Supercritical Whitcomb Airfoil Micro Drone Propeller (30.72g thrust @3V)

thingiverse

The propeller was designed by using the **Boeing KC-135 Winglet Supercritial Whitcomb** airfoil. Testing was done using the **[Drone Propeller Thrust Testing Jig](http://www.thingiverse.com/thing:2302071)** You can inspect the results below. Part printed at slow speed, with a **[0.2mm extruder nozzle](http://amzn.to/2qQdFvg)** at 0.04 height per layer. I deburred and cleaned the print using an **[X-ACTO Knife](http://amzn.to/2pV1sGA)** After this, it was sanded with a piece of **[500 grit sandpaper](http://amzn.to/2pTNwic)**. Here are the thrust measurements for a few voltage presets (also visible in the pictures taken): - **1.5V** => **7.35 grams** - **2V** => **11.02 grams** - **2.5V** => **23.24 grams** - **3V** => **30.72 grams** The files you can download consist of all the pictures taken during the test, along with 6 txt files that contain airfoil coordinates, the STL files and the SLDPRT files. Should you want to play with the propeller, make sure you have a couple of **[8520 coreless motors](http://amzn.to/2qPUhi4)**. Use the SLDPRT files, should you want to adapt the propeller model to suit your own needs. **Notice:** The airfoil plotted by using the matplotlib library for python.
