| Abstract | ||
| This paper presents the investigation on electromagnetic launch for single stage coilgun. The proposed coilgun and its excitation circuit were designed for launching small objects few meters. A transient simulation for the projectile motion through the launcher was done using transient finite element commercial software ANSYS MAXWELL. Also a comparative comparison between different parameters is introduced including the effect of number of turns, voltage, induced current and length of coil on the exit velocity of projectile while leaving the barrel. Detailed studied cases have been investigated. The results confirm a direct proportional relation between the velocity of projectile and number of turns, voltage and induced current in coil while confirming an inverse proportional relation with the length of coil. | ||
