Abstract

Traditional aircraft configuration design attempts to achieve improved performance and reduced operating costs by minimizing maximum takeoff weight. From the point of view of an aircraft customer, however, this method does not guarantee the optimality of an aircraft program. Multidisciplinary design optimization (MDO) is an important part of the aircraft configuration design process. This paper addresses a systematic approach in aircraft configuration design optimization. It first discusses the design parameters, constraints, objectives functions and criteria and then aircraft configuration classifications. Then the relationship between each major design option and the design requirements are evaluated. Then the systems engineering principals are presented. At the end, systems engineering approach is applied in the optimization of the aircraft configuration design and a new configuration design optimization methodology is introduced.
