Electromagnetic Rail Launcher as a Circuit Element

Abstract

The circuit equations for the inductor driven rail launcher are integrated numerically using a fourth order Runge-Kutta method. Their solution is also obtained as a perturbation expansion for small resistance. The EMACK parameters are used to study the results. For high current shots the full numerical solution agrees with the first order approximation to 3%. For low current shots they agree to 5%. A very simple zeroth order approximation agrees with the full numerical solution to 5% in the high current case and to 3% in the low current case.
