An airfoil wing generates lift since it's equally curved and tilted back, And so the oncoming air is accelerated over the top surface area and then pressured downward. This makes a region of lower tension right higher than the wing, which generates lift. The wing's tilted angle forces the air downward, and that also pushes the aircraft upward (Newton's 3rd regulation). Discover our far more within our posting on airplanes.
