Design, fabrication and test of a 250 m/s generator-driven coil launcher

This study deals with the design, implementation and real time test of a generator-driven, full-scale 250 m/s Linear Induction Launcher (LIL). The paper presents a condensed but comprehensive design guideline for such a type of launcher, explains in detail the implementation process, and discusses the test results. Additionally, effects of different materials, different thicknesses, and different lengths of the projectile on the muzzle velocity of the launcher are also examined to obtain a comparison facility for the projectile. The paper clearly explains and experimentally shows step-by-step how a coilgun-type generator-driven EML is designed and fabricated, including barrel design, projectile design, power source and power conditioner design.
