Finite-element analysis for the active electromagnetic armor projectile interceptor

Along with the continuous development of the intellectualized antitank ammunition and the application of the future electric gun in the battlefield, the armored vehicles encounter an increasingly heavy threat in the battlefield. So the armor protection has to develop new technologies so as to enhance the armored vehicles´ survivability in the battlefield. A new concept practical application of the pulsed power technology-active electromagnetic (EM) armor was discussed in this paper. It combined the intellectual fire-control, advanced detector, and precise EM projectile interceptor. It must be the developing direction of the active protection system. A structural and mathematical model of the active EM armor projectile interceptor based on the principle of single stage coil launcher is given in this paper. It analyzes the effects of the electric parameter in the discharge circuits and the structural property of the interceptor to the launching velocity and efficiency of the interceptor. Finally the model is simulated numerically by finite-element analyses.
