Performance Optimization on Multiple-Stage Synchronous Induction Coil Launcher Considering Hindrance Effect

In this article, the hindrance effect of multiple-stage synchronous induction coil launcher (MSICL) during the emission procedure is analyzed. Considering the direction of the coil emission current and induced current, a new method to restrain the hindrance effect is proposed in this work, which can reduce the current operating time and increase the armature exiting speed. Based on this method, an eight-stage SICL is simulated by the finite element algorithm (FEA), including the electromagnetic force, armature speed, and the distribution of the magnetic field, etc., which shows that impact of the hindrance effect can be greatly improved.
