Abstract:
1. An armor arrangement designed to reduce or eliminate the effect from armor-piercing projectiles, the arrangement comprising: at least two inertly reactive armor modules comprising crystals or piezoelectric elements arranged on continuous surfaces of inert material of the at least two inertly reactive armor modules and configured to generate electrical voltage when the inertly reactive armor modules are penetrated by a projectile part or projectile effect and in dependence on mechanical vibrations or shock waves; at least one explosive reactive armor module; and voltage, current and/or energy-detecting member(s) designed, in dependence on the said voltage generation by the elements on the continuous surfaces, to detect a site of a point of penetration on a surface of the arrangement which is exposed to weapon action and, in dependence on the detection, to calculate a velocity of the projectile part or projective effect and if the velocity exceeds a predetermined value, to produce energy or a signal for initiation or triggering function(s) of the at least one explosive reactive armor.
