Abstract:
1. An active armor system for protection against a shaped charge capable of producing on detonation a shock wave and a jet comprising a first armor layer having a front face and a rear face; a second armor layer positioned in spaced generally parallel relation to the first armor layer and having a front face and a rear face; a third layer adjacent the first armor layer which is a medial layer having a front face and a rear face and which is positioned between the first armor layer and the second armor layer and which is comprised of a magnetostrictive material selected from the group consisting of a material having a formula of Tb.sub0.27 Dy.sub0.73 Fe.sub2 and a material having a formula of Tb.sub0.27Dy.sub0.73 Fe.sub1.95; and an electrical connection between the first armor layer and the second armor layer, whereby on detonation of the shaped charge sufficient electrical energy is generated to disrupt the jet and thereby prevent penetration of the armor system.
