中文摘要：

重接炮是利用磁力线重接而对弹丸产生推力的电磁发射形式。多级重接炮的关键就在于各级能量的有序释放。本文介绍了重接炮的工作原理，设计了一套多级重接炮的发射控制方案和速度测量系统。以一个自制的三级重接炮系统为基础，实现了其系统控制和速度测量．获得了发射过程中的速度数据及其曲线。对本系统而言，当储能电容器组充电电压为3500V时，160g弹丸的发射速度可达24．991m／s。

英文摘要：

Reeonnection gun is a type of electromagnetic launcher whose propulsive force is generated by the magnetic field line reeonneefion. The key point of multi-stage reeonneetion gun is the discharge of preserved energy in sequence at different stages. The principle of reeonnection gun is introduced. A control project of multi-stage reeonneetion gun as wellas the velocity measurement system are presented on the basis of a fabricated three-stage reconnection gun. The velocity data and its curve during the launch process are attained. A pill of 160 grams can be accelerated to 24.991m/s when the energy storage capacitor banks are charged to 3500V.
