摘  要：电磁线圈发射器具有弹丸和炮管无机械接触、力学结构合理、效率高、适于发射大质量载荷等优点。20世纪90年代以来美国在多个方向开展了电磁线圈发射技术的研究，该文主要介绍美国电磁线圈发射技术在军事领域的三个应用：电磁迫击炮、电磁飞机弹射系统和电磁导弹助推器。从美国电磁线圈发射技术的发展现状可以看出，电磁线圈发射技术主要应用于发射低速大质量弹丸，具备高储能密度及快速充放电特性的高功率脉冲电源仍是制约电磁线圈发射技术的关键因素，同时精确的同步控制技术和新材料技术的发展将扩大电磁线圈发射技术的应用领域并加快其实用的步伐。

Abstract:  Electromagnetic coil launcher had superiority of no contact between the barrel and the projectile, rational dynamics structure, high launch efficiency and capability to launch weightily loadLots of researches into electromagnetic coil launcher were being done in USA since 1990 Three kinds of applications including electromagnetic mortar, electromagnetic aircraft launch system, electromagnetic missile launcher were introduced Seen from electromagnetic coil Launching technology development in the USA, it was mainly applied to launching the projectiles with low velocity and big massPulsed power with high energy storage and rapid charging and discharging was the key factor to restricting the coilgun progressThe development of the precision fire-control of the barrel coils and the new materials would expand the applications.
Key words: electromagnetic coil launching technology; electromagnetic mortar; electromagnetic aircraft launch system; electromagnetic missile launcher
