Nic,

Again I’d need to counter the assertion that the shape of the upper surface is directly responsible for the low pressure generated there. The 'airfoil' shape is really just there so that the...

This is my favourite page on how wings really work: http://www.regenpress.com/

It does cover surface attachment (aka 'Coanda effect')

I think it's a mistake to infer that Newton and Bernoulli are 'competing theories' or that Bernoulli applies only to the top of a wing and Newton only to the bottom. It's also incorrect to think of...

That's kinda hard to answer without going into some depth, and it's probably getting rather off the original topic anyway..

Very briefly..
I'm not sure where you get 4 degrees from? Each airfoil...

Yes, your right, Bernoulli never worked on wings or lift theory.

Air travelling over a convex surface does indeed produce a low pressure on the surface but the reason has nothing to do with...

Not sure what you mean by this:confused:

A gliders CG position is not really relevant to where it's forward 'thrust' comes from. A glider that has a rearward CG flys forward just the same as any...

Feel free to expand on the article if you wish, there are still many areas that could be improved upon.

The actual Wattwiki article (http://www.wattflyer.com/forums/vbglossar.php?do=showentry&id=2)(unlike this thread) is really very very basic and as simple as can be... have you read it?

Ray,
Maybe I was a bit abrupt in my reply, it a fault of mine for which I apologise.
Criticism and comment is more than welcome but it may be more meaningful and better received if made after...

Ray,
How much simpler do you want it than "planes generate lift as a reaction to turning air downward"? Which is what I modified the Wiki article to say and which is technically correct. Please take...

Bear in mind I’ve no formal education in aerodynamics; I’m just a model flyer with an interest in the physics involved.....


Circulation and vortexes are not two aspects of lift, they are both...

As no one has commented i propose to modify the WattWiki page to correct the error regarding lift theory..

This is what i have in mind to replace the existing 'lift' section:

As well as debunking the incorrect lift theories NASA have a pretty simple page on how a wing really works some of which could perhaps be incorporated into a corrected version of the new WattWiki...

Mike,
Unfortunately the section on 'how wings generate lift' is incorrect (both parts).
