Dynamic research of multi-stage reluctance coil gun

In order to increase the velocity of the armature, it needs lots of driving coils to discharge, and accelerates the armature continuously. It conducted theoretical analysis of the three-stage reluctance coil launcher, and established the model of the three-stage reluctance coil launcher. At the same time, it conducted dynamic simulation by the way of position trigger with the Ansoft software, and analyzed the influence of the trigger position to the properties of the three-stage reluctance coil launcher in the point. The analysis shows that the trigger position has the bigger influence to its properties in the design of the multi-stage reluctance coil launcher. Each driving coil has the best trigger position to make the armature muzzle velocity and energy conversion efficiency maximum. The research would conduct the follow-up design and experiment of multi-stage reluctance coil launcher.
