What is the best wing design for a plane?
Tapered: wing narrows towards the tip. Structurally and aerodynamically more efficient than a constant chord wing, and easier to make than the elliptical type. Trapezoidal: a tapered wing with straight leading and trailing edges: may be unswept or swept. An elliptical planform is the most efficient aerodynamic shape for an untwisted wing, leading to the lowest amount of induced drag.
Which principle is used in designing the wings of airplanes?
Aircraft wings generate lift through a principle called Bernoulli’s Principle. The upper surface of the wing is curved, while the lower surface is flatter. As air moves over the wing, it travels faster over the top and slower underneath. Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.Air moves more quickly over the curved upper surface of the wing than it does under the wing, which has a flatter surface. The faster moving air produces less pressure than the slower moving air, causing the wing to lift toward the area of low pressure.
