Modelling of a parallel augmented railgun with pspice validation of the model and optimization of the augmenting circuit

Experiments with LARA, a 15 mm caliber parallel augmented railgun at the French-German Research Institute ISL, have shown that the augmenting circuit of this railgun was not efficient. In order to minimize the energy losses in the augmenting circuit of this railgun, a PSSpice model was developed. This model combines an electrical model of the pulse forming network and the rails with a model of the kinematics of the projectile.
