ac, you have never studied anything even remotely concerned with this
discussion. And no, a CNN sound bite does not qualify as "study". Neither does
reading a Popular Mechanix article.

Thanks, spock.

It's good to see someone actually talking about something they've studied,
rather than "heard about"...

A voice of reason in an echoey kinda place...

Try some "Bernoulli experiments for kids",and you will reach a better
understanding.

no, you won't. wings/sails do not have lift because of "Bernoulli"
inspite of
the fact you can read such in thousands of kiddie books.

Yes you will. Been there done that. Its fun and will definitely teach
you allot of how aerodynamics works in the real world. These simple
"Bernoulli experiments for kids" can show you exactly how a wing or
most any solid object can generate lift as a result of the Bernoulli
effect. You could write a book on what these experiments will teach
you.

In a feeble attempt to prove the misconception that an airplane wing
(while in normal flight) produces lift as a result of Bernoulli
effect, these kiddy and adult books give perfect examples of Bernoulli
effect lift. My favorite is the levitating ball. The large problem
with this is that a wing in flight is not partially influenced by a
stream of air that has reduces internal pressure as a result of its
increased velocity. A wing in flight is totally submerged in the
relative airflow that is influencing it and many times this relative
airflow has no velocity at all because the aircraft is flying in still
air.

So to generate Bernoulli effect lift from a wing simply direct a jet
of air over the top of it. If you want a wing in normal flight to
produce Bernoulli effect lift your are pretty much crap out of luck as
you apparently already know.
