The well-rounded, cambered airfoil sections well-suited to subsonic flight speed are generally not appropriate for high-speed and supersonic flight. Supersonic airfoils are distinctive in their geometric shapes in that they are thin (i.e., have a low thickness-to-chord ratio) with sharp leading edges. Supersonic airfoils … See more Engineers must know how to select or design suitable cross-sectional wing shapes (often called airfoil profiles orairfoils) for use on a diverse range of flight vehicles such as airplanes, various … See more The basic geometry of an airfoil is described in terms of a profile shape or envelope that defines the curvature of its upper and lower surfaces.
