摘　　要：针对灵敏度分析可以更深入地分析设计参数对飞机生存力的影响变化,研究了将灵敏度分析应用到飞机生存力设计的方法.基于飞机敏感性、易损性和作战能力模型建立了飞机生存力计算模型,分为旧机改型设计和新机方案设计两种情况对设计参数进行了灵敏度分析,为旧机改型设计中待改进参数的选取和新机方案设计中设计变量初始范围的缩减提供了依据.仿真实验及结果分析表明了文中方法的可行性.Since parameters sensitivity analysis can analyse the effects of design parameters on aircraft survivability more in-depth, the method of applying sensitivity analysis to aircraft survivability design was stud- ied. The calculation model of aircraft survivability was established based on the model of aircraft susceptivity, vulnerability and combat capability. The parameters sensitivity analysis was divided into two cases of the modi- fied design of the old aircraft and the program design of new aircraft, which provided the basis for the selection of parameters in the modified design and initial range reduction of design parameters in the program design. Simulation results show that the method is effective and feasible.
