固体电枢电磁轨道炮的发射过程具有很高的精度和稳定性。以小口径固体电枢电磁轨道炮系统为研究对象,通过对试验结果的分析和试验数据的处理,建立了改进型GM(1,N)灰色分析模型,实现了固体电枢初速的高精度拟合,结合膛内瞬态温度测量结果对发射过程的一致性进行了分析研究。分析结果表明,参数不变的条件下,合理匹配电枢质量和电枢直径将有助于稳定固体电枢电磁轨道炮初速的一致性。

The launching process of electromagnetic railgun with solid armature can provide the high precision and stability. Taking small caliber electromagnetic railgun with solid armature as a research object, the improved GM （1, N） model was established based on the analysis of experiment results and the treatment of experiment data, and the high precision fitting of solid armature muzzle velocity was realized. The consistence of launching process was analyzed combined with the measurement results of transient temperature in chamber. The measuring results showed that the reasonable matching of armature mass and diameter can be helpful to improve the consistence of muzzle velocity of the electromagnetic railgun with solid armature.
