Can the shape of a wing help obtain lift?
Yes. Wing shape and speed are the two main factors in obtaining lift. The typical wing design has a mostly flat bottom side and a more curved top side. The leading edge of the wing bulges upward on top so that air crossing the wing is pushed upward. The bulge then thins out, sloping downward toward the wing’s rear. The result of this difference in shape between the top and bottom of the wing is that there is less air pressure above the wing than below. The greater pessure under the wing pushes upward, creating lift.
