@Federico Very interesting research, but the writer of the article did a terrible job of explaining the chart.

@Federico I understand that. The overall net effect is downward turning, thus lift. What I’m confused has two parts. The flow is turned upward before it turns downward. Which seems like it would create downward lift at the front of the wing and upward over the rest (from a Newtonian POV). The second part is that, at the LE Bernoulli would predict upward lift due to lower static pressure, whereas Newton would predict downward lift due to reaction force of air being forced upward.

The location of center of pressure on an airfoil at 1/4 chord shows that Bernoulli is correct. The wing gets more of its lift from the LE than the rest.

The, sort-of, explanation I give myself is that most of the upward motion, at least in that image I posted above, takes place away from the surface of the wing - too far to have an effect on it. There’s only one streamline that is actually moving upwards while close to the wing, but two or three of them are close enough to have an effect past the LE. But that’s just conjecture to satisfy my cognitive dissonance :\
