The following animation illustrates the principle of dynamic lift. For this purpose, an aircraft with a Clark-Y airfoil is shown. The angle of attack of the wing can be changed. The acting forces, shown as vectors, adapt accordingly.
If you click on the large content window of the animation, further layers are visible. The polar diagram shows how the lift and drag coefficients of the wing relate to each other. As an alternative to the polar diagram, an analytical diagram is also displayed.

The phenomenon of dynamic lift is not understandable at first sight. As a layman, one would not expect that a wing with the angle of attack of 0 degrees would still cause lift. In the animation you can see a real Clark-Y profile. Actual measured coefficients for lift and drag are used. The aim is to make students think and marvel by showing them as true to the original as possible.
