Flapping airfoil
Did you know?
WebAn airfoil (British English) or aerofoil (American English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine.. A solid body moving through a fluid produces an aerodynamic force.The component of this force perpendicular to the relative … Webin this regime. An example of the dramatic change in efficient airfoil shapes crossing this “barrier” becomes clear in the overview presented in Figure 3, by Lissaman.11 It should be noted that the dragonfly and pigeon wing airfoil profiles are used in highly unsteady “flapping-wing”
