Analysis and Optimization of Intercepting Effect Mechanism of Multistage Synchronous Induction Coil Launcher

In view of the influence of the interception effect on the dynamic characteristics of the multistage synchronous induction coil launcher during the launch process, the principle of the “interception effect,” which is the inherent characteristic of the multistage synchronous induction coil launcher, is analyzed. The multistage synchronous induction coil launcher finite element simulation model is established in this article, and through simulation calculation, the influence of the discharge current of the last-stage drive coil on the launch performance of the multistage synchronous induction coil launcher is studied. It is proved that the armature interception effect can be greatly reduced by changing the current direction of the last stage of the drive coil, thus improving the firing performance of the coil launcher.
