一、引言目前,已能利用电磁炮把重几克到几百克的弹体分别加速到10公里/秒或4.5公里/秒,这种高推力是一般火炮无法比拟的。电磁发射技术有可能在很多领域中获得应用(图1)。近几年来,美、澳、日等国都已制订了电磁发射器的研制计划。美国的洛论茨利弗莫尔实验室、洛斯阿拉莫斯实验室、得克萨斯大学电磁中心、波香通用动力公司、国家航空和航天局、国际应用物理以及威斯汀豪斯公司,澳大
I. INTRODUCTION At present, it has been possible to use electromagnetic guns to accelerate bullets from several grams to several hundred grams to 10 km / s or 4.5 km / s, respectively. Such high thrusts are unmatched by general artillery. Electromagnetic emission technology is likely to be used in many fields (Figure 1). In recent years, the United States, Australia, Japan and other countries have formulated the development plan of electromagnetic launchers.
