Posted: Fri May 14, 2010 9:54 am Post subject: Bernoulli or Newton?

I was distressed some years ago when I discovered that airplanes fly  mostly due to Newton's laws with very little lift attributable to Bernoulli's  principle--all those years of grade school wasted! Bernoulli's principal helps a  bit, but by far it is Newton's angle of attack "push" that keeps our wonderful  Zenith's in the sky. One way to verify this is to look at an aerobatic airplane  with symmetrical wings--if Bernoulli's principal is the reason airplanes fly, a  symmetrical wing would not fly. Below is a report funded by NASA  affirming that Newton's laws are the reason that airplanes fly.

Hi Jeff,

If you've ever seen rime ice formation on a symmetrical wing in flight, 

you'd notice the lift is well forward and lacking on the lower side 

which says, yes, angle of attack is

part of it, but the principal of airflow distance over a wing is 90% 

main reason it flys at all.

Jeff,  Thanks so much for sharing the very informative article by the Allstar network.  As a flight instructor for almost 40 years, it time to let go of the notion the "world is flat" and move on.  Thanks again,   Jim Sagerser

Thank you. I am pleased to see that I am not the only person who believes  that Newton is what keeps us in the air. 

  

 Larry - you have got to read and understand "Stick and Rudder" Even Sabrina  will understand when she meets Dr. Drela at MIT. Congratulations girl!

What theory of Newton is keeping us in the air?

Newton's 3rd law. It's all in the attachment.
