Theory and Method of Aircraft Multidisciplinary Design Optimization:Current Status and Future Direction
Multidisciplinary Design Optimization(MDO)is referred to as a methodology that enables optimal design of a complex engineering system and its subsystems,through exploring and utilizing the collaborative mechanism among disciplines in engineering systems like air vehicles.First,the development of 1st-and 2nd-generation MDOs and its application to aircraft and spacecraft designs is reviewed,after shortly reviewing the fundamental concepts and application background of MDO.Second,for the under developing 3rd-generation MDO techniques,literature review is conduced to show the current status and future challenge of MDO key technologies,such as coupled multidisciplinary numerical simulation,MDO architecture,multi-fidelity method,efficient global multi-objective optimization,topology optimization,robust design optimization,anti-numerical-noise optimization and generic integration architecture.Finally,the key issues as well as the suggestions for future research and development are presented,towards meeting the needs of 2035 target.
