Somers S102 Sharp Airfoil Micro Drone Propeller (26.71g thrust @ 3V)

thingiverse

I designed this drone propeller using the Somers 102S Sharp airfoil and tested it on the Drone Propeller Thrust Testing Jig, which can be found online at http://www.thingiverse.com/thing:2302071. The results are shown below. To print the propeller, I used a 0.2 nozzle with a height per layer of 0.04mm and printed slowly. After printing, I cleaned and deburred it using a Precision Knife available online at http://amzn.to/2pV1sGA. Next, I finished the propeller by sanding it with 500 grit sandpaper found on Amazon at http://amzn.to/2pTNwic. Here are the thrust measurements for various voltage levels: 1.5V yields 3.24 grams of thrust, 2V yields 9.83 grams, 2.5V yields 19.01 grams, and 3V yields 26.71 grams. You can also view these results in the images taken during the test. The included files contain all the pictures from the test, along with six text files containing airfoil coordinates, printable STL files, and SLDPRT files. If you'd like to modify this propeller, I recommend using an 8520 coreless motor available on Amazon at http://amzn.to/2qPUhi4. For more control over the design, use the SLDPRT files to make your own changes to the drone propeller. Note: The airfoil was plotted with matplotlib in Python.
