摘要: 采用一元非定常特征线理论分析了单级轻气炮的发射性能,给出了储气室长度,储气室与发射管截面积比,弹丸质量,破膜压力和环境压力等参量变化对弹丸运动规律的影响,还得到了发射过程中弹丸底部压力的变化规律,为轻气炮的工程设计和性能计算提供了一个较好的方法。

Abstract: The performance of one-stage launchers with chamber age is analysed in this paper by the method of characteristics. Influence of the reservior length,the launch-tube length, section area ratio between chamber and launcher barrel and the projectile mass are investigated individually. Variation of the base pressure during the entire launching process is obtained. This method can be used to calculate the performance of light-gas guns.
