You don't have to read the book from front to back. Flipping through it, you should find plenty of interest. I get it though. You just don't want...
Theory of Wing Sections is not a textbook. It's mostly a collection of easily understandable data and straightforward explanations. I think any...
No, I think I suggested that a long way up this (or some other) thread.
Whether you like it or not, the fundamentals are the same for sails, wings, or hanging your arm out a car window. You don't need a reference...
I'm not messing with you. The source of the force is given in the one sentence that I quoted (and also in the 1st sentence of baeckmo's answer.)
Quoting from Theory of Wing Sections: "The surfaces that support the aircraft by means of dynamic reaction on the air are called wings." To...
Would a figure like this one help narrow it down? [ATTACH]
Sorry, what tripped me up was that I recognized 0.00256 as the density of air in slugs/ft^3 and didn't bother looking at the rest of the terms. In...
I hate to quibble, but your units aren't consistent. You haven't converted the speed from mph to ft/sec.
Milne-Thomson's argument takes less than two pages. You consider that long & involved?
Good grief! When you started posting, I was sure you must be a troll. Then you started sounding like you really did want to learn. Now I'm back to...
There's also the tangential skin friction which contributes to the force - mainly to the drag component.
If the lift is independent of Mach number, it's hard to argue that you need to consider Mach number effects.
For once, why can't you just read what is presented to you and try to understand it, rather than asking some irrelevant thing!
Here are two pages from a basic aero textbook (Theoretical Aerodynamics by L.M. Milne-Thomson) explaining the issue you have. What, exactly,do you...
So nothing can convince you that, if you extended curves like this all the way to zero Mach number, they wouldn't be close enough to horizontal?...

Polars don't assume anything about the current. The speeds they use are boat speed and wind speed (both with respect to the water) There's no...
Many is probably an exaggeration. AC50's and other fast foilers can certainly do it. Not too many others can.
The wind coming from behind you allows you to sail just like sailing downwind in the ocean. To make progress up the river you have to head up and...
