Keywords: supersonic transport, aircraft design, shape optimization, aerodynamics, computational fluid dynamics

To improve aerodynamic performance and reduce the design cost, an aerodynamic design tool, which combines a CFD code with a gradient-based optimization technique, is developed. The paper describes optimization design technologies and some applications conducted for a jet-powered experimental supersonic airplane.
