Cambridge Professor Dispels Lift Myth

 - January 31, 2012, 3:05 PM

University of Cambridge Professor Holger Babinsky has created a one-minute video to dispel the myth that an airplane wing generates lift because the airflow moving over the upper surface has a longer distance to travel and “needs to go faster to have the same transit time as the air traveling along the lower, flat surface.” What actually causes lift, he said, “is introducing a shape into the airflow, which curves the streamlines and introduces pressure changes–lower pressure on the upper surface and higher pressure on the lower surface.”

This guy dispelled the myth? I cringe at the thought that this is taught anywhere.

Anyone with any understanding of physics would know that there's no reason for equal transit. for the record, the nasa website for k-12, the wikipedia page on lift, both dispel this myth and one would hope that k-12 educators or anyone playing an instructive role on the subject would at least check these two sources first before passing on that sort of drivel

ok the video is actually pretty cool to see with your own eyes.
