Friend Pat

There are quite a few citations re: lift comma airfoil. The first one  

that comes to mind is: http://www.allstar.fiu.edu/aero/ 

airflylvl3.htm. I have several on another computer I use for research  

and writing, so I'll crank it up shortly and begin to flood you with  

citations.



In '42 Navy PreFlight the staff was still preaching the Bernoulli  

Dogma, which most all avcads had been exposed to in high school. And  

it's still be taught that way today, in many schools/places. And in  

the Fall of 1903, my late father was in a physics class at Indiana  

University where the professor was writing equations on the  

blackboard, proving that heavier-than-air machines could not fly!



For further info on fluid mechanics, look up Ludwig Prandtl and Kutta- 

Jukowski...partial differential equations will help.

regards,

Bob N.

Pat,



Here are three more that are still active:

Hi Bob,



No they ain`t.  Only the first URL worked. The second connects to some 

Eskimo page and the Washigton one is u/s.



As it happens there is an article re Bernoulli and Newton in the `FLYER` 

magazine delivered yesterday so I haven`t absorbed it all yet but it seems 

from a cursory glance that BOTH theorems are valid.

As usual there are specific conditions laid down. SMOOTH airflow, less than 

.4 Mach for instance.



The `flat plate` argument much employed in our recent discussions about 

airflow around tail feather is not as simple as I thought, although I am not 

convinced that I was completely wrong.  It all hinges apparently on the 

Stagnation Line. This is the imaginary line where  the air flowing over the 

top surface separates from the air going underneath. When the tailplane is 

aligned straight into the airflow there are equal quantities of air going 

over and under and no lift is generated. When the front edge of the 

tailplane is lifted the Stagnation Point moves slightly under and back from 

its leading edge. The air going OVER the surface then has slightly farther 

to go   and we are then back with the familiar pressure drop etc.



I think my brain is full.



Thanks Bob



Cheers



Pat

Hi Pat,



        Don't tell my R/C foamie 'flat plate' planes about that Bernoulli 

stuff.  They'll all stop flying!



        As for the 'greater distance' theory, the aerodynamics engineering 

folks at UND took that to task over 20 years ago, as have others since. 

Basically, there's nothing in physics that says the air molecules have to 

'meet up' at the trailing edge.



        My head is starting to hurt now, too.

Hi Guys & Gals,



Hmmm what makes a wing lift? I believe aerodynamics has nothing to do =

with it.=20



Cash is what makes a wing lift!  No two ways about it, no money =3Dno =

flying.



Sad but true I'm sorry to say.



I have the receipts to prove it....



Best Regards

Carlos G.

Good one Carlos.  No bucks, no Buck Rogers!

.... and the faster they go, the cash amount rises exponentially!
