Agreed.mailee":23z7wk6j said::?: :?: :?: it would help to know what your theory is first? Air travels faster over the upper surface of the wing creating a lower pressure so lifting the wing, as far as I know :?
I assume that your understanding was that this difference in air speed was due to: for adjacent air particles at the front of the wing, the one that goes over the top of the wing has to travel faster so that it can meet up again at the back. This causes less air pressure above the wing. This is the explanation is often given but it doesn't make sense as there's no reason for the 2 air particles to need to be together at the back of the wing - they're not connected in any way.RogerS":23z7wk6j said:My theoretical understanding is, apparently, wrong!
What do you think?
It's a good theory. After all, a very similar mechanism is keeping the British economy going (and more so the Euro), even as I type. ;-)RogerS":2jn021bo said:So Theory 1 says that it is the belief of the passengers that it can fly. That's what keeps it up in the air...
... Personally I believe Theory 1.
They require an angle of attack. It still isn't anything to do with pressure differential between top and bottom though.Steve Maskery":1ubbk3yf said:John
But does you symmetrical wind fly when it is level like that? Surely it only flies when it is tilted up at the front? Or at least, tilted down at the back (ailerons, are they called?). In which case the pressure differential still holds.
