Almost everything you thought you knew about winglets is actually wrong. All the other Youtube channels and even Wikipedia talks about how winglets are there to stop wingtip vortices, this is not correct! I found this out, to my astonishment, when I was researching for a completely different video and started talking to a great aerodynamics expert and friend of mine called Björn Fehrm. In this video I will try and explain why winglets has nothing to do with stopping wingtip vortices and everything to do with aspect ratio and wingspan. Enjoy my friends! Now!
