本文运用外弹道学的理论对各种类型的航弹的运动稳定性作了较为系统的研究.推导了不自转航弹的运动稳定性条件和稳定性判据.在弹体座标系下,运用无量纲化运动方程组这种新的方法导出了低速自转航弹、尾翼自由旋转式航弹的动态稳定性条件、共振条件和稳定性区域图.指出了马氏力矩系数的符号对航弹快慢圆运动的不同影响.阐明了尾翼自由旋转式航弹这种新型结构对运动稳定性带来的好处. 在本文的撰写过程中,得到了浦发教授的热心帮助.在此谨表衷心的感谢.
In this paper, we use the theory of outer ballistics to systematically study the motion stability of various types of cruise missiles, and deduce the motion stability conditions and stability criteria of non-rotating projectiles.In the coordinate system of projectiles, The new method of non-dimensional equations of motion is used to derive the dynamic stability conditions, resonance conditions and stability of the low-speed self-propelled and tail-rotor free-roiling missiles. Different effects of fast and slow circular motions.It clarifies the benefits of the new structure of free-revolving tail-rotor to sports stability.In the writing of this article, I got the ardent help from Professor Pudong. .
