| 摘 要： | 给出了一种能够用于统计分析飞行器再入大气层时，头部烧蚀而产生不对称形变过程的数学模型，烧蚀外形采用典型化处理方法。通过对美国ＮＲＶ样例的试算表明，头部形变的主要参量与实测数据符合较好。

| Abstract: | A mathematic model is presented to describe the small asymmetric shape change of reentry yehicle nosetips during atmospheric entry.The model is suitable for statistical analysis of nosetip shape change histories. Nosetip shape histories are characterized by "typical" method. Numerical solutions for the NRV sample are obtained. The calculation results of primary parameters of nosetip shape change show consistency with the in-situ measurements. |
