Abstract
Electromagnetic launchers (EMLs) including railguns, helical guns, and coilguns have been proposed for numerous applications. However, little information has been published regarding the scaling characteristics of EMLs. This investigation examines the non-linear operating characteristics of EMLs to derive the operating voltage and current scaling relationships as determined by the mass and velocity of the projectile and the length of the launcher. The scaling relationship is derived using the kinetic power relationship common to all types of EMLs. The scaling relationship is expressed as a simple function of projectile velocity, projectile mass, and launcher length. Resistive losses are included in the results as is the EML's energy conversion efficiency.
