National Aerospace Laboratory (NAL) is promoting the development of two scaled supersonic experimental airplanes : a non-powered airplane and a jet-powered airplane. In the aerodynamic design, NAL originally developed a CFD-based inverse design method and an optimum design method. The former was applied to the supersonic natural laminar flow (NLF) wing design of the non-powered airplane and the latter was used in optimizing the aerodynamic shape of the jet-powered airplane. The NLF wing design concept was validated by boundary layer stability analysis and wind tunnel tests with low freestream turbulence. The optimum design method consists of Euler analysis with overset grid system and adjoint method. This method was especially applied to non-axisymmetrical fuselage and nacelle shape.
