飞行器智能设计愿景与关键问题

Nowadays, the aircraft has been more and more autonomous and intelligent, and their missions have been more complex. Various types of aircraft have been developing, such as hyper sonic aircraft, highly stealth aircraft, and morphing aircraft. Thus, to fully achieve the comprehensive performance of the aircraft, an intelligent and multidisciplinary-integrated design process needs to be developed to improve the traditional decoupled design process. In this paper, the problems existing in the traditional aircraft design process are firstly discussed. Then, an intelligent and full-life-cycle aircraft design framework is proposed. In this closed-loop aircraft design framework, the knowledge base is applied to connect the stages of design, manufacturing, and operation and maintenance. The intelligent digital twin technology is employed to simulate, analyze and predict the states of aircraft, so as to update the data needed in the process of aircraft design and operation. The key technologies and basic scientific questions are discussed, and suggestions on the intelligent aircraft design process are given.
