The Application of Multidisciplinary Design Optimization in Aircraft System Design

Aircraft system design involves many different disciplines,including lots of design variables,state variables,constraint equations and interrelationship.It is believed as a kind of typical complex system.To improve design quality and integrated performance of aircraft,an engineering way to realize the aircraft system multidisciplinary design optimization was presented based on MDO technology system with consideration of the characteristics of aircraft system design to realize aircraft system multidisciplinary automatic design and optimization,making initial parameters is more reasonable in aircraft system conceptual definition stage.
