多学科设计优化方法在飞机设计中的应用研究

Research on Application of Multidisciplinary Design Optimization Methods in Aircraft Design

多学科设计优化(MDO)方法是提高飞机设计效率,得到最优设计方案的有效手段。在飞机设计过程中,需要确保飞机静安定裕度满足使用要求,因此需要充分考虑总体、气动等学科专业的耦合效应。针对这一问题,基于MDO软件Modelcenter构建飞机外形多学科优化协同设计流程,通过对某型飞机外形优化设计的实例分析,得到该机的最优外形修改方案,证明了MDO方法在飞机设计中应用的高效性。

Multidisciplinary design optimization（MDO）methods are the effective means to improve the aircraft design efficiency and achieve the optimal design scheme.During the process of aircraft design,the pitching static margin of aircraft must meet the usage requirement,therefore the coupling affections between general layout and aerodynamics must be considered.To solve this problem,apracticable solution is proposed.The collaborative MDO process of aircraft configuration is created based on Modelcenter.The MDO of a certain aircraft configuration is taken as an example.The optimal configuration scheme of this aircraft is obtained.The high effective of MDO methods applied in aircraft design is proved.
