Mastering Airfoil Selection for Drones - Part 1: Theory

[@MTFTVlive]

Easily the most comprehensive video on the intenet. I've been searching for something like this for weeks, imagine my surprise seeing this video was only a day old. Subscribed!

Thanks for the feedback! Stay tuned for part 2 which will offer many practical tips and tricks for airfoil selection. If you have any other topics you would like us to cover, feel free to let us know.

@@SIMNET_aero yeah I’d love to see differences between pusher and puller prop configurations aerodynamically, I’m currently trying to build a 3d printed fixed wing drone using the inrunners from an junked $20 quad

Thanks, this is a well-presented video. Looking forward to whatever else you produce on the subject of low-speed aerodynamics.

[@FPVREVIEWS]

The video touched on the subject but didn’t actually talk about it. That’s the forward shift in CP with increase of AOA. Dealing with the effects of camber on the pitch of the aircraft, maintaining stability without losing efficiency is a major design challenge and something for consideration when choosing the overall aircraft configuration. It’s actually possible to achieve aerodynamic instability with dynamic stability at the same time with no moving parts.

Amazing! Well explained

05:39 You are missing something. When calculating the CL and CD it is not by the chord c, but by a surface of reference. Otherwise, the dimensional analysis and results don't check.

Very good video! I like it a lot. Can i make a suggestion to change colour of airfoil and graphs for brighter for better visibility of diffrences :-) Good luck with Your project!

[@SIMNET_aero]

Thanks for your comment and suggestion, we'll improve the image contrast for part 2 of the series.

2:25 You should specify it better. From your description you can have a relatively thin (5-6%) undercambered airfoil and the max difference betwwen upper and lower surface would make it something like 7-8%.

The correct lift equation has the aircraft wing area and not the wing chord

[@FrontSideBus]

Don't you mean an aerofoil?
