Research on Structural Parameters of Single-stage Multipole Field Launcher Based on Uniform Design Approach

Compared with the traditional electromagnetic propulsion configuration, the multipole field electromagnetic launcher (MFEL) system has numerous adjustable parameters, and the change of any parameter affects the efficiency of system. An effective method to improve the efficiency of system is proposed through the analysis of the energy coupling formula of armature. An uniform design experiment is established by taking the turns of monolayer and layers of drive coil, the thickness of armature, and spaces of drive coil and armature as variable factors. The experimental data is analyzed, and the matching pairs of optimal structural parameters are obtained. The simulation results show that the efficiency of optimization model is improved significantly. A reasonable design scheme for the MFEL major structural parameters is presented after analyzing each simulation.
