design companies including Boeing and Airbus are more advanced. Since the
first successful use of supercritical wing on the A320 by Airbus, the subsequent A330, A340, A380, and A350 adopted this type of wing (as shown
in Fig. 7.51, 7.52, 7.53 and 7.54). Boeing’s B737-800, B747-8, B787, etc.,
also use supercritical wings (as shown in Figs. 7.55, 7.56, 7.57). The large
