Luis, I understand where you are coming from, but I have to tell you this. I mde that statement with an idea of making it easier for people to understand lift and some of the ways it is created. If you disbelieve me, then I must say that all the experiments that I have conducted must not worth a thing.

You see, I have been part of experiments where a colored drop of fluid was imparted into the steam stream we were using to test a wing in a wind tunnel. The tunnel used, the half dozen computers, with 4 dozen digital video cameras, all watching this an measuring the effects, WITH ALL BEING THE ABSOLUTE STATE OF THE ART IN DESIGN AND FUNCTION, would say that the molecules do actually seperate and meet again at the trailing edge of a wing at the same time. The only time this not true is when you pitch the wing to extreme angles for its design, and start to make the air seperate from the top, or bottom, of the wings surface. At this time, they still meet up again, and still they are at meeting again, just this time at the point of equal pressure.
I don't mean to be rude, but if you don't believe that, then was does this happen with the full scale airplanes. Another experiment was to see if by seperating the flow of air from over the wing will it cause the wing to stall and not create lift. The FAA, NASA, and the USAF have done MULTIPLE studies and experiments showing that the moment the airflow does not conform to one side of a wing, the wing is in a stalled condition and will NOT generate lift until the flow of air is restored! I have been part of this type of experiment as a pilot!!! I have seen it MANY times!!!

I am not trying to be rude. Please if anyone takes me as that, I humbly apologize! But I try to state things in a way that makes it easy for people to understand what is goin on with airplanes while in flight, and on the ground. I agree that under the most techincal of terms, I may be slightly wrong. But we are talking about something that is very simple to understand if you knock it down to its most basic of forms. If you are an engineer, then it needs to be more specific (which leads to the types of disagreements we have here.) But for most of us, we just want to make an airplane that works with a .40 or .60 sized engine!

Thanks,

Reg
