I'm not sure that's a real thing that happens in real life or theoretical physics.
If the airfoil isn't moving, is anything happening? Or are you talking about a non-moving airfoil with air moving around it? It's impossible to tell the difference between a non-moving airfoil with air moving around it and a moving airfoil with still air around it, given that they're equivalent provided you define the reference frame correctly.
- nimish 7y agoYeah I used the wrong term: an airfoil that isn't changing its shape or being used like a bird wing, where there's more going on than just in a fixed-wing aircraft. But yes, the relative motion is what matters.
