| 摘 要： | 提出一种将飞行器参数化建模、灵敏度分析与气动/隐身综合优化设计相结合的方法.该方法的流程为:(1)建立面向多学科设计的参数化模型,提取分级参数;(2)对分级参数进行灵敏度分析,筛选设计变量;(3)基于分级优化流程,应用多目标优化算法进行飞行器气动/隐身综合优化设计.以一个四尾翼布局飞行器气动/隐身综合优化设计为例,阐述流程的实现过程,结果表明这种方法具有如下优点:(1)多学科参数化建模为气动和隐身性能分析提供统一的参数化模型;(2)使用灵敏度分析工具对分级设计参数进行筛选,精简优化设计任务;(3)基于分级参数和灵敏度分析进行分级优化设计,优化适应值提高56.1%,耗时减少57.02%.
