A 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 orders of magnitude greater than the total . This is an example of a homologous structure.
