Study on designing driving coil with cooling chunnel of Electromagnetism Drive

Electromagnetism Drive is launcher which utilizes magnetic traveling wave produced by impulse or alternating current to drive projectiles with coil or magnetic material, essentially is a linear electric motor. The heat wasting affect coil gun´s efficiency and capability, high temperature of driving coil will reduce its life, indeed burnout coil, and when enhancing firing rate, we need calculate effect of temperature rising. The paper have designed and produced driving coil with cooling chunnel, have changed conventional flat copper line to hollow copper.
