Re: [Phys-l] question about Bernoulli

[chuck britton <cvbritton@mac.com>]

Supersonic wings are not 'airfoil' shaped if I understand correctly.
Angle of attack certainly enters in to upside down flight as well.

Doesn't air flow faster over the top of an airfoil?
Isn't the pressure lower?
How far off are the numbers for Bernoulli to have a hand in things?

Not many folks will claim that Bernoulli is the WHOLE answer.
Does that mean it has to be ZERO part of the answer??

Have aeronautical engineers been duped all these years?
