摘要
为获得高速破片、稳定弹道性能,自行设计加工了用于破片发射的气动脱壳弹。分析了该气动脱壳弹气动脱壳的原理及气室的充排气规律,计算了某火炮发射该气动脱壳弹时不同气孔面积和气室容积下其气室的压力变化,分析了影响该气动脱壳弹设计的关键因素。分析结果证明:气孔面积和气室容积在气动脱壳中起着非常重要的作用,是该种气动脱壳弹设计的关键要素。
In order to obtain high-speed fragments, stable ballistic performance, designed and processed the gas-propelled sabot-discarding pill for launching fragments. Analyzed the principle of gas-propelled sabot-discarding and the gas-filling and exhaust gas law of gas chamber, the motion of the gas-propelled fragments has been carefully calculated under the different spiracle areas and gas chamber volumes during the discarding process in certain artillery, and the key factor influencing the design of the gas-propelled sabot-discarding pill has been analyzed. The results show that the stoma area and the gas chamber cubage play a very important role in the gas-propelled sabot-discarding motion, it is a key factor of gas-propelled technology.
