Simulation Analysis of Discharge Position Influencing on Performance of Reconnection Launcher
摘要
Abstract
In order to obtain high exit velocity and high energy conversion efficiency of reconnection coil launcher, the firing position and pulsed current waves need to be optimally designed. The propel processes are theoretically explained, and the propel efficiency of electromechanical model is analyzed based on physical equations. The influence of discharge position on acceleration force, exit velocity and propel efficiency is simulated by electromagnetic finite element method. Simulation results indicate that best firing position which makes the projectile attain the stronger acceleration force and maximal velocity is in existence. Simulation analysis shows that brake force exists during the launch process and the maximal muzzle velocity does not correspond with maximal propel efficiency. For the maximal propel efficiency of multi-stage reconnection launcher, the discharge position should be optimization, and the current wave of drive coil requires optimum matching to the mutual inductance gradient curve.关键词
