火炮子母弹抛撒段子弹运动规律初探

基于火炮子母弹抛撒过程的特点，提出了抛撒段的概念，建立了母弹中各层串子弹的坐标变换关系，进行了受力分析，推导了抛撒段子弹运动微分方程，求解了子弹自由飞行的起始条件，为子弹刚体外弹道的分析计算和子弹引信受力环境的识别利用奠定了基础。

ON THE LAWS OF SUBMUNITION MOVEMENT IN THE EJECTION AND SCATTERING SECTION OF A CARGO PROJECTILE

Based on the character of the ejection and scattering process of a cargo projectile, the concept of ejection and scattering section is put forward, the relationship of coordinate alternation of each layer and cluster submunition in the cargo projectile is established, the analysis of the bearing force is conducted, the differential equations of movement of submunition in the ejection and scattering section are deduced and the initial conditions of free flight of the submunition solved. All of these lay a foundation for the analysis & calculation of the submunition's external trajectory as a rigid body and for the recognition and utilization of the environmental force acting on the submunition fuze.
