自旋弹道导弹模型及运动特性分析

自旋是弹道导弹的一种新的突防手段,在助推段进行滚动飞行,可以减少强激光照射的驻留时间,有效对抗激光反导。但是导弹自旋会导致控制耦合、惯性耦合和气动耦合,而且会随着滚速的增加,耦合增强,俯仰和偏航通道的相互干扰会对自旋稳定飞行产生较大的影响。开展了这方面的初步研究,建立了自旋弹道导弹模型,通过时域的仿真初步分析了弹道导弹低滚速的滚动飞行特性,得到了有益的结论。

Model and Flying Traits Analysis of Spinning Ballistic Missile

Spin is a new kind of method for ballistic missiles puncture. To survive from lasers attacking, ballistic missile can spin during the first boosting phase that can reduce the dwell time of a beam on a particular point on the missile. But when the missiles spinning, control, inertia and aerodynamic coupling will make pitch and yaw movement interaction, and this will influence the stable spinning. This paper will do some pilot study on this. Model of spinning ballistic missile is established. The spinning missiles traits are studied by simulation in time domain, and some useful conclusions are drawn.
