An airfoil is a cross-section of an aeroplane wing, which is having a curved surface so that it will provide coefficient of lift (Cl) and coefficient of drag (Cd), which is most important factors required for aeroplane flight by the aeroplane wings, or the generated forces may also be used by propeller blades, etc. when the shape of the airfoil changes, their aerodynamic characteristics also change. The airfoil is also very useful because it suspends completely bulky weight of airplane in air. Therefore, the design of airfoil is when moved with certain required speed it produced some useful...
