The finite element analysis for the magnetic of the active EM 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 together. Compared with the powdered projectile interceptor used in the present active protective technology, the pulsed projectile interceptor has the characteristics of short trigger delay time, good controllability, and repetition uniformity. 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 was given in this paper. It analyzed 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 simulated numerically to the model by the finite element analyses.
