The Research on the Launching Consistence of Small Caliber Electromagnetic Railgun

Abstract

Electromagnetic railgun can perform precision strike in long range. It is obtained that the scatter of velocity must be exist because there are many effectors influencing launching process, for example, the manufacturing error, the initial value of launching parameters and uncertainty during launching process and so on. Among these factors, the parameters of armature are easy to adjust to ensure the consistence of velocity. So we attempt to apply Grey Analyzing Model to carry on the study, and then by means of the measurement of strain on the barrel to verify the model. The result shows that the reasonable matching of armature mass and diameter can be helpful to improve the consistence of armature muzzle with the other parameters the same. This method is a new attempt to study the stability and consistence of velocity of solid armature.
