Abstract: The aerodynamic design method or iginally for a single lift ing surface based upon the iterative r esidual correction principle is developed for designing multi-lifting surfaces. An aerodynamic design code based on this methodis integrated wit h other advanced aer odynamic analysis codes to design multi-lifting sur faces. Using such an aerodynamic design software package, a wing configur ation with a canard is studied and designed.

Key words: iterative residual correction principle, multi-lifting surfaces, canard configuration, aerodynamics, design
