The questions about the wing lift show complete lack of understanding of the basic physics by ChatGPT.
The Coanda effect is caused by viscosity (the adjacent layers of air transfer some of the momentum of molecules between them), and the wing material also transfers momentum to adjacent layer of the air (causing parasitic drag). This causes the air flow to “stick” to the top surface (to understand how just look at the streamlines to see how the speed gradient from wing to undisturbed air bends the flow) and so be deflected downwards, which creates lift (Newton’s 2nd and 3rd laws).
Without viscosity there is no lift (this is known as Kutta condition).
Now. Bernoulli’s principle is independent from viscosity (it’s a consequence of conservation laws), and so cannot be a correct explanation of aerodynamic lift.
(The loss of “stickiness” of laminar airflow over upper wing surface by transitioning to turbulent flow is known as wing stall, and causes rather abrupt loss of lift when the angle of attack goes approximately above 18 degrees—again, according to Bernoulli principle the stalls would be impossible, but any pilot can easily demonstrate that they do, indeed, exist).
Just face it—ChatGPT is just a Chinese Room. Repeating any popular nonsense from the training set without any deeper understanding or generalizing.
