The aerodynamic design of an SST (SuperSonic Transport) configuration with some geometry requests at given flight condition in 3rd NAL-SST-CFD (Computational Fluid Dynamics) workshop competition subject 1 is conducted by following three design tools: a conventional linear theory design tool, a CFD-based optimization tool and a CFD-based inverse design tool. In order to increase a Lift to Drag ratio (L/D) of the airplane, several design concepts are adopted such as a warp wing design, linear and non-linear area-ruled fuselage designs and a supersonic NLF (Natural Laminar Flow) wing design. The non-linear area-ruled fuselage design shows that the CFD-based optimization design tool can improve the aerodynamic properties of the airplane designed by the conventional linear theory design tool. As for the NLF wing design, however, the CFD-based inverse design tool should be carefully coordinated in order to realize the target NLF pressure distributions.
