When I was learning to fly, which was quite a while ago, I was told Bernoullis theory explained lift. However, for some time now it has been apparent that his theory (and it's still a theory) is wrong. It was developed by studying incompressible fluids in pipes. As explained at
http://wright.grc.nasa.gov/WWW/K-12/...ne/right2.html Newtons second Law of Motion can be used to explain lift.
The next page (arrow on bottom of page) explains why Bernouillis Theorem is wrong. Is anyone still being taught this theory of flight, and if so, why? Or is this heresy?
Amazing that, a hundred years on, we're still not sure, 100%, why wings do fly.
