摘要: 气推式脱壳穿甲弹以其结构简单,脱壳干扰小,无自伤等优点而具有广阔的应用前景.本文对它的弹托气室与外界环境之间的充排气规律进行了研究.在此基础上,建立了气推弹脱壳运动的动力学模型,给出了脱壳过程中弹托与弹芯的起动条件和分离判据.计算了某航炮用气推弹脱壳运动情况,指出了气孔面积对气室储压、脱壳时间及脱壳距离的影响.Abstract: With the advantages of simpler Structure, smaller disturbance and no self-hurt while discarding sabot, the gas-propelled amor-piercing projectile with discarding sabot (APDS) owns its promissing prospect. This paper has studied the gas-filling and ejecting characteristics between the gas chamber in sabot and the environment. Adynamical model describing the sabot-discarding process has been establihed. Theauthors have also given the slarting condition and the parting criterion of the partingmotion during the sabot-discarding. The motion of the gaspropelled APDS has beencarefully calculated Finally, the effect of the gashole area has been analyzed not onlyon the pressure in the gas chamber near the barrel exit, but also on the sabot-discarding time and distance away from the barrel.
