导轨炮固体电枢设计与实验研究(英文)

DESIGN AND EXPERIMENTAL RESEARCH ON SOLID ARMATURE IN THE RAILGUN

在分析固体电枢结构和电热特性基础上进行了设计与实验，实验结果表明，在高速时导轨有轻微烧蚀，电枢弧压很低为５０～１００Ｖ，并由于初速不同转捩速度亦不同，电枢耗能显著降低，故提高了发射效率并降低了烧蚀．实验结果与理论结果吻合较好．

In this paper, the solid armature (SA) has been designed and experimented on the base of analysis on its structures and various electrothermal properties. The experimental results show the rails have slighter damage with high velocity and low armature voltage of 50-100V, converting velocity is different because of its initial velocity for the SA, and the energy deposited in the SA in the bore can be reduced significantly. So using of the SA may raise launching efficiency and decreasing erosion. The experimental results agree well with the theoretical results.
