In wing design, as wing planforms strongly depend on the sectional airfoil design, it is obvious that optimum airfoil will be different if multipoint aerodynamic performance of wing planform differs. Thus, this paper consists of two parts. In the first part, to obtain quantitative knowledge of multi-point supersonic aerodynamic performance of various wing planforms, the liner theory is investigated using the computational fluid dynamics (CFD). For a given supersonic cruise speed, when the leading edge of the wing becomes the subsonic edge, our theoretical study says the higher swept-back wing has the lower zero-lift drag. On the other hand, when the leading edge of the wing becomes supersonic edge, the lower swept-back wing has the lower zero-lift drag. This result suggests the having a lower swept-back wing will be a reasonable choice for the aircraft which flies at a certain supersonic speed. Secondly, multi-point designs of the supersonic wing using efficient global optimization (EGO) were considered for two kinds of planform; one is cranked arrow wing which has high sweep-back leading edge, another is taper wing which has sweep-back leading edge. According to the analysis of design results, different optimum airfoil geometries are obtained between each planform and it is also shown that the shape of the camber line of airfoil plays an important role for both the planforms in order to reduce wave drag in supersonic cruise.
