摘要
在对膛口流场进行简化的基础上，研究了气推式脱壳弹脱壳过程中弹托与弹芯的起动条件和分离运动。对某航炮用气推弹在膛口流场中的受力进行了工程估算，并计算了该弹的脱壳运动情况，分析了气孔面积对脱壳时间的影响。
Based on the simplifications of muzzle flow field,this paper studies the starting condition and parting movement between the sabot and the rod of a gas-propelled APDS duing the discarding process.It estimates the forces acting on APDS in the muzzle field and calculates the movement of sabot and rod.It also analyzes the effect of gas hole area on the time of sabot discarding.
