摘要
针对小型化慢旋再入飞行体在再入过程中有可能发生的联锁滚转共振现象,从六自由度弹道方程出发,建立了一种联锁滚转共振的搜索模型;对联锁滚转共振时的轨道参数进行了搜索计算,提取出易于检测和识别的特征参数;在此基础上提出了一种易于工程实现的联锁滚转共振特征参数的检测方法,并对联锁滚转共振特征参数检测装置进行了设计和仿真,最后给出了实验室半实物仿真的结果。
Point to the persistent rolling resonance which may be take place during the slowly revolving reentry body reentries, a kind of search model of the resonance, which is based on the six-free ballistic equations is built. The trajectory parameters of this kind of resonance are calculated and the leading features which are easy to be tested and identified are extracted. After that, a test method which is easy to realize in engineering is brought forward, a test device is designed and a simulation is carried out. At last, the simulation result is stated in this article.
