| 摘要: |
| 在临近空间飞行器飞行试验任务中，运载器与飞行器之间的分离多数在临近空间发生。飞行器与箭体之间的气动特性，对分离过程的安全性有重要影响。然而，分离过程的动态特性和飞行器外形的复杂性给气动特性的正确预测造成了巨大困难，地面试验也很难验证。为此，发展了Monte Carlo打靶分析方法，在误差带宽内随机生成气动特性，通过增大气动特性的覆盖性，大大提高了气动特性对分离过程的安全性影响评估的正确性和可靠性。 |

| Abstract: |
| In the hypersonic vehicle flight experiment, separation between hypersonic vehicle and launch vehicle will take place in the near space The separation aerodynamic characteristic plays an important role on security in separation process However, because of complex configuration of vehicles and dynamic characteristic for separation process, the aerodynamic characteristic for separation process is difficult to be simulated with numerical method or in wind tunnel experiment The Monte Carlo simulation method is developed to improve the validity and reliability for evaluating the separation process through stochastic aerodynamic characteristic being incumbent on error bound |
