Current aircraft industry design practices produce high quality, safe, and affordable aircraft. However, future advanced and integrated methods offer the opportunity to significantly reduce the cost and development time of aircraft designs. This paper presents an overview of the current design process and an example for subsonic transport wing box design. It also describes a future process which is presently being implemented at the Douglas Aircraft Company, i.e. the Aeroelastic Design Optimization Program (ADOP), and its application to a similar subsonic transport wing. Specifically, stress and flutter are optimized and compression surface buckling and tension surface damage tolerance are integrated. Finally, the future direction of ADOP will be outlined which includes integration of aeroelastic loads, durability and damage tolerance, and concurrent structure and active controls optimization.
