Hi,
in my point of view lift is created as a result of two pressures, the static and the dynamic.
The dynamic pressure is the dominating creator of lift at large angles of attack. For example a flat plane at 45 degrees will create lift.
The static pressure is the dominating creator of lift at small angles of attack. For example the curved airfoil at 0 degrees can produce lift by increasing speed over the airfoil and reducing it under. Increased speed increases the dynamic pressure and lowers the static (as a result of Bernoullis law) but as the static pressure is dominating it results in lift.
But what happends at large angles of attack? is the curved shape decreasing the lift as it decreasing the dominating dynamic pressure under and increases it over the airfoil?
Cheers, Simon.
