| 摘 要： | 为研究弹道修正过程中弹丸转速的变化情况,在建立脉冲修正弹角运动方程组的基础上,分析了转速变化的影响因素,推导了脉冲修正后弹丸的平衡转速.根据修正弹道的特点给出了脉冲结束后弹丸转速的变化规律.研究表明,脉冲作用的径向偏心是造成弹丸转速大幅变化的主要原因,转速变化的剧烈程度与脉冲冲量大小、径向偏心距及脉冲发动机工作个数有关...

| Abstract: | To research the change regularity of projectile rotation speed in trajectory correction process,the influence factors of rotation speed were studied based on angular motion equations of impulse correction projectile.The balanced rotation speed was deduced after impulse correction.According to the characteristic of correction trajectory,the change regularity of rotation speed of projectile after impulse action was obtained.The study result indicates that the radial eccentricity caused by the impulse action i... |
