Boeing HSNLF Airfoil Micro Drone Propeller (41.98g thrust @ 3V) by emanuelbucsa

Last crawled date: 3 years ago

This propeller was designed using the "BOEING HSNLF AIRFOIL". It was tested on the Micro Drone Propeller Thrust Testing Jig (results below).
It was printed slowly, with a 0.2mm nozzle at 0.05 layer height. Check out the printing details below for more information.
Cleaned with an X-ACTO Knife, then sanded with 500 grit sandpaper.
Here are the thrust readings for a few voltage values (you can also view these in the images):
1.5V => 15.23 grams
2V => 21.42 grams
2.5V => 27.04 grams
3V => 41.98 grams
The included files contain all the pictures taken during the test, along with 6 txt files which contain the airfoil in various positions (rotated, scaled and translated on the Z axis), the STL files and the SLDPRT files. If you want to use this propeller, make sure you get a 8520 coreless motor.
If you were to reassemble them, insert them in SolidWorks as "Curves through XYZ" in ascending order. Then, through a few processes, you can get to the design of this propeller. You'll notice the Z value is incremented by 5mm each time. If you modify this value, you'll end up with either a longer or a shorter version of the propeller blade.
Use the two SLDPRT files, in case you want to make your own changes to the propeller.
Notes: Airfoil plotted using the matplotlib library in python.
