The general philosophy and methodology behind a computer-aided conceptual aircraft design process are discussed. The building blocks of the computer system are examined, with emphasis on aerodynamic optimization and design. Drag reduction at design conditions is performed in interactive process including internal component arrangement and preliminary structural design, producing a highly cohesive air vehicle evolution. When interactive computer graphics and analysis techniques are used throughout the process, from initial design to analysis output, a consistent data base is developed which provides an added integrity and realism to evolving configurations. Finally, the improved efficiency of the design system over previous fragmented methods is demonstrated illustrating time and cost reductions. Improved interface between disciplines which were previously decentralized is also achieved. (DePo)
