膛内弹丸运动时电磁特性研究

Measurement and Utilization of Electromagnetic Characteristics of Projectile's High Velocity Movement in Gun Tube

通过在弹丸内不同方向装载线圈,测量弹丸在膛内高速运动过程中的电磁信息,从而分析内弹道中弹丸的电磁特性与运动特性。测试系统利用了与外界无连线的存储测试方法,得到了弹丸在膛内高速运动过程中的电磁信号。该测试信号可反映弹丸的加速,出炮口运动等信息。经过特征提取用于引信的设计中,可作为引信发射环境识别的有效手段。

Setting coils of different directions in projectile can measure the electromagnetic signals of fire in the gun tube,The characteristics of electromagnetic and movement can be analyzed through these signals.The measurement system utilized memory method which have no connection with outside,and the data have been measured through shot test.The projectile s acceleration and out—tube information can be get from the signal.These information can be used for fuzes design to improve fuzes environments recognize ca...
