| 摘要: |
| 本文研究不对称再入弹头滚动共振特性。将运动方程建立在不随弹头慢旋的坐标系上，利用线性化方法进行近似研究。研究了不对称弹头由于慢旋对滚动共振的影响，给出避免发生滚动共振的慢旋角速度公式，并研究了当慢旋角速度较小时，慢旋引起的可能发生持续滚动共振区域的变化。 |

| A Study of the Characteristics of the Roll Resonance of an Asymmetrical Re-entry Vehicle |

| Abstract: |
| This paper is a report on study of the characteristics of the ro11 resonance of an asymmetrical re-entry vehicle. The equations of motion are described in a coordinate system which does not spin with the vehic1e.
The effects of the spinning of the asymmetrical vehicle on the persistent ro11 resonance has been studied with the linearzation method. Also a formula of spinning speed is derived to avoid the persistent ro11 resonace.
It is show that the region in which the persistent ro11 resonance may occur will vary with the spinning speed when it is more slow. |
