| 摘 要： | 在主动段进行姿态稳定是提高远程火箭弹射击密集度的有效技术措施，实施了姿态稳定后，火箭弹的纵向散布仍然偏大．文中采用统计实验法，通过大量的弹道仿真对姿态稳定火箭弹的纵向散布特性进行研究，计算结果表明：总冲跳动和质量偏差是造成纵向散布的主要原因；主动段终点弹道倾角散布在大射角时对纵向散布影响小，在小射角时对纵向散布影响大；速度极小点参数比主动段终点参数与射程有更强的线性相关性．

| Abstract: | Attitude stabilized technology is very us ef ul to reduce the dispersion of long-range rocket, but the range dispersion of a ttitude stabilized rocket is not very satisfactory still. In this paper, the sta tistical experiment method is used to simulate the trajectory of attitude stabil ized rocket and the range dispersion characteristics are studied. The simulation data indicate that the range dispersion results mainly form the dispersion of t otal impulse and mass deviation; the trajectory tilt have more influence on rang e at small fire angle than large; and the trajectory parameters of velocity mini mum point have stronger liner relationship with range than that of burnout point . |
