1.前言过去的火炮是采用燃烧火药产生气体推进炮弹的方式,在原理上就限制了炮弹的速度。为了得到“任意大”的速度,早在第二次世界大战时期,德国人J.Hansler就曾试制用电能取代火药的化学能的电磁炮。据了解当时只完成了将10克重的弹丸加速到1,200米/秒的速度,而没有取得满意的结果。战后这项研究工作进展缓慢,最近几年再次得到有关方面的重视。据说在美国将300克左右的弹丸加速到3.000米/秒的速度已取得成功。
1. Introduction The artillery of the past, which used the method of burning gunpowder to generate gas to propel artillery shells, in principle, limited the speed of artillery shells. In order to get “any big” speed, as early as during World War II, the German J. Hansans had tried to use chemical energy to replace gunpowder cannon electromagnetic guns. It was learned that only 10 grams of projectiles were accelerated to 1,200 m / s at that time without satisfactory results. The post-war research work has been slow and has received the attention of the parties concerned again in recent years. It is said that in the United States, the speed of accelerating about 300 grams of projectiles to 3.000 m / s has been achieved.
