Three dimensional simulation of electromagnetic railgun’s exterior ballistics

In order to evaluate the electromagnetic railgun's practical combat capability as well as its tactic application prospects, a three dimensional simulation model of electromagnetic railgun's exterior ballistics is presented. On the hypothesis of the Earth's being round and ignoring the influence of rotation, the railgun's atmospheric environment and its motion equations are established by the Simulink Module of Matlab. And the railgun's characteristics of exterior ballistic under different muzzle energy and emission inclinations are discussed. Results show that its incomparable superiority in improving range and lethality to conventional artillery under the same launch condition based on railgun's range and variation of velocities. It is useful for the efficacy evaluation of railgun's combat capability and its practical applications in fields such as ground war, missile interception and so on.
