National Aerospace Laboratory (NAL) is working on a project "Supersonic Research and Development Program" to establish the advanced technology for the next generation supersonic transport. In this program, two types of unmanned scaled supersonic experimental airplane, i.e., non-powered and jet-powered, will be developed, and flight tests at supersonic speeds will be made to demonstrate the new and advanced technology such as CFD aerodynamic design methodology. This paper describes the aerodynamic design and the estimated performance of the supersonic air-intake for the jet-powered supersonic experimental airplane. The air-intake is two-dimensional external compression air-intake with variable geometry of which the design Mach number is 2.0. Preliminary flow passage design is based on 1D empirical method and the design data base of NAL but detailed configuration such as bleed configuration and side wall configuration is designed being based on 3D CFD analysis.
