摘要
回顾飞机总体优化设计的传统方法 ,介绍多学科优化方法在飞机设计中的应用状况和最新发展。重点讨论为解决设计变量过多和计算耗费太大问题提出的试验设计和响应面近似法以及带不确定性多学科优化的鲁棒设计方法。提出飞机总体优化设计的一些关键研究领域 :气动—结构、气动—隐身、结构—主动控制等 。
The traditional approaches to conceptual/preliminary design optimization of aircraft were reviewed. The applications of multidisciplinary optimization methods to aircraft design and their recent developments were presented. Emphases were laid upon the design of experiment and the response surface approximation, which are used to deal with the problem with overabundant design variables and with extreme computational expense. The robust design methodology for the multidisciplinary optimization with uncertainty was also stressed. Some critical research fields including the integrated optimization of aerodynamics structure, aerodynamics stealth, structure active control, etc. have been put forward. Finally, a prospect is given for the potential application of multidisciplinary optimization to the conceptual/preliminary design of aircraft.
