提出了采用复模态分析方法研究非平稳大气紊流对弹性飞行器的影响。首先给出了非平稳随机大气紊流模型；然后提出了弹性飞行器对非平稳随机大气紊流激励的复模态分析方法，该方法把复杂的随机动力响应计算问题转化为复代数运算问题，为研究飞行器对随机大气紊流的响应开辟了新的途径；最后以某型地一空导弹为例，计算其对非平稳随机大气紊流的响应，从而说明非平稳随机大气紊流对弹性飞行器的影响．
A complex modal analysis method is proposed to study the influence of non-stationary atmospheric turbulence on elastic aircraft. Firstly, a non-stationary stochastic turbulence model is presented. Then, a complex modal analysis method for elastic stochastic turbulence is proposed. This method transforms complex stochastic dynamical response problems into complex algebraic problems. The research on the response of aircraft to stochastic atmospheric turbulence opens up new avenues. Finally, taking a certain type of surface-to-air missile as an example, its response to non-stationary stochastic atmospheric turbulence is calculated to illustrate the impact of non-stationary stochastic atmospheric turbulence on elastic aircraft .
