AbstractIn this research, the supersonic wing design problem for SST with integrated engine intake and nacelle is discussed to obtain design knowledge of the supersonic airfoil in view of wing planform dependency in realistic configuration. Two planforms were considered ― a quadruple tapered wing with a high sweep-back angle and a single tapered wing with a low sweep-back angle. To reduce the computational time, the design problems were solved by a multi-fidelity design method, which is the evolutionary computation based exploration using the hybrid surrogate models based on two different physical fidelity results. The hybrid surrogate model which was combined Kriging model with radial basis function (RBF) makes optimizations more efficiently than Kriging model. To evaluate the aerodynamic performance, the compressive Euler equation and the linearized compressive potential equation were employed as two different fidelity solvers. Through optimum designs, two kinds of design knowledge are obtained. Firstly, in airfoil design, the shape of the forward camber and twisted angle have the largest effect on drag reduction. In case of low sweep-back wing, an airfoil which has small positive camber and small twisted down angle has found to be optimum. On the other hands, In case of low sweep-back wing, an airfoil which has a negative camber at the leading edge or higher twisted down angle compared to low swept-back wing’s one has shown to be optimum. Secondly, the way of aerodynamic interference between wing, engine, and fuselage depends on planforms.
