Dynamic Performances of the Electromagnetic Rail Launcher

To obtain a rail-type electromagnetic launcher with large electrodynamic force, low temperature rise, and high structure strength, this paper investigates the performance of a pulsed current electromagnetic rail launcher (EMRL). According to the investigation, the inductance gradient and current-carrying capacity are determined. Based on the analysis of mechanical properties of the EMRL, armature, and bolt, the corresponding conclusions are achieved. These conclusions will establish the foundation for further research on the mechanism of the rail-type electromagnetic launcher.
