Abstract
The accuracy of the muzzle velocity greatly affects the probability of the projectile hitting the target, and it is one of the key indicators that must be analyzed of one launcher. Based on this, the influencing factors of the muzzle velocity accuracy of the synchronous induction coil gun are analyzed, and a three-stage synchronous induction coilgun is designed. A two-dimensional axisymmetric model of the three-stage coilgun is built using Maxwell 2D, based on which, the effects of the voltage of each coil’s pulse power supply, the resistance of coil, the resistivity of armature, the projectile mass (These 4 parameters vary in range ± 10‰), the initial position of armature (vary in range ± 2 mm), the trigger time of each coil discharge (vary in range ± 0.1 ms) on the muzzle velocity are calculated. The degree to which each parameter affects the accuracy of the muzzle velocity is analyzed according to the calculation results. These results have certain reference significance for the optimization design, performance improvement and application expansion of synchronous induction coilgun.
