炮口高速等离子气体及飞行弹丸对感应装定影响的试验研究

炮口感应装定是一个高速动态过程，在详细分析弹丸飞经感应区间过程的基础上，研究了测试炮口高速等离子气体和高速弹丸对感应装定系统影响的方法，设计了3项测试内容。通过耦合测试线圈，测得了炮口装定信号耦合曲线。结果表明高速电离气体形成的电磁场影响了感应装定系统信号传输，通过在炮口装置上开泄气孔的方式，可以减小它对感应装定信号传输的干扰；高速飞行的弹丸改变了感应装定区间的电磁场分布特性，使感应耦合信号幅值降低。

Experimental Study on the Influence of High Speed Plasma Gas and Flight Projectile on the Inductive Setting in Muzzle

The muzzle inductive setting is a dynamic process of high speed. Based on analyzing the process of the projectile flying through the inductive setting field, an experimental method was studied to test high speed plasma gas and high speed projectile influencing on the inductive setting system. Three tests were designed. The real-time coupling curves of the inductive setting signal were tested by coupling test coilsl The experimental results indicate that the electromagnetic field formed by high speed plasma gas can influence the signal transmitting of the inductive setting system, and the influence can be lowered by opening vent on muzzle; the high speed projectile can change the distributing characters of the electromagnetic field in the inductive setting zone, which reduces the amplitude of the inductive coupling signal.
