WebA wing is a type of fin that produces lift while moving through air or some other fluid.Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils.A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio.The lift a wing generates at a given speed and angle of attack can be one to two … WebThe wings of a bird are flapping, but the wings of an airplane are fixed and cannot be flapping. So birds are not afraid of stall, and even use stall (differential pressure resistance) to generate more force to reduce speed. Note that the bird will flap its wings in the direction of speed when landing. Share.
