摘　　要：通过六种在工程设计上应用的实例,阐述国内飞机设计单位当前在飞机设计的各个阶段,利用现代优化技术所开展的气动弹性优化工作。内容涵盖机翼、尾翼、全机、常规金属结构、复合材料结构气动弹性优化建模和优化设计方面的问题;涉及飞机初步设计、详细设计和改型设计等多个阶段。应用结果表明:使用作者提出的基于遗传/敏度混合优化方法的现代优化技术,可以很好地解决现代飞机设计各个阶段的气动弹性建模和结构优化问题,达到提高设计效率、提升设计水平的效果。Aeroelastic optimization projects are illustrated using six engineering design examples. They are based on modern optimization technology, and in different stages of aircraft design. In the illustration, aeroelastic modeling and optimization design of wings, tails, and full aircrafts are presented, and both metal and composite materials are taken into account. The proposed modem genetic/sensitivity-based hybrid optimization method is applied to preliminary design, detail design and retrofit design. It is shown that efficient aeroelastic modeling and optimization design are achieved in different design stages, which is helpful to increase design efficiency and improve design quality.
