文摘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 iir saber and the environment. A dynamical model describing the sabot-discarding process I?as been established The authors have also given the starling condition and the parting criterion of the parting motion during the sabot-discarding. The mellon of fire gas-propelled APDS has been carefully calculated. Finally, the effect of the gashole area has been analyzed not only on the pressure in the gas chamber near the barrel exit, but also on the sabot-discarding time and distance away from the barrel.
