WebAerofoil or airfoil refers to a cross-sectional shape whose design takes place with curved surface that provides the most favourable ratio between lift and drag in flight. Furthermore, lift is the component such that the force turns out to be perpendicular to the motion’s direction. In contrast, drag is the component that is parallel to the ...
