弹箭运动作为时变系统动态稳定性判据

CRITERIONS OF DYNAMIC STABILITY FOR ROCKETS AND PROJECTILES AS A SYSTEM WITH ITS PARAMETERS TIME CHANGEABLE

本文考虑无控火箭、炮弹扰动运动微分方程的联解性,并将其分成参数缓变和普变两种情况,导出了无控火箭、炮弹飞行运动作为时变系统的动态稳定性判据。

The criterions of dynamic stability for unguided rockets and projectiles with its motion equations as a time changeable system are achieved in this paper in consideration of coupled solution of differential equations of rockets or projectiles motion which are divided into two cases, they are, the one with its parameters slowly changing and the one with its parameters normally changing.
