The Effect of Coil Geometry and Winding Method on the Electromagnetic Launcher Performance.

Electromagnetic launchers become spread in many applications. This type of launcher is used to accelerate a slug made of ferromagnetic material. Many researchers compete to enhance the performance of this type. The launcher consists of simple components such as a capacitor bank, electronic switches, launcher coil, and charging circuit. In this paper, the authors have physically built the launcher system and reinforced the launcher performance by changing the winding method and making the trigger coil in a conical shape to reduce the deceleration effect of the last half of the trigger, this modification has proven its superiority over the straight coil.
