Abstract: A momentum trap ballistic armor comprises an accelerating layer, a plug layer adjacent to the accelerating layer, and an energy absorbing layer. The plug layer includes an opening and at least one plug maintained within the opening. When a projectile impacts the accelerating layer, the plug is accelerated to the velocity of the projectile before the projectile perforates the plug, forming a projectile-plug combination. The energy absorbing layer is used to capture the projectile-plug combination. The accelerating layer is typically ceramic, the plug layer is typically metal, and the energy absorbing layer is typically ballistic cloth material.

Abstract: The invention describes a rigid or flexible pyrotechnic protection surface which is free or integrated into a housing, for medium-heavily and lightly armored vehicles, protection arrangements and surfaces to be protected, corresponding to FIG. 1, with a single-layer or multi-layer carrier (4) of any configuration which is inclined in the region of action of the threat and pyrotechnic layers (2, 3) mounted on the carrier on both sides. Shock waves and reaction gases are formed by the firing of both layers and are accelerated both in opposite relationship to and also in the direction of the penetrating hollow charge threat (1). In that way both the front powerful blast elements and also a great blast length are disrupted and thus lose their penetration capability or are at least greatly diminished in respect of their residual power. The pyrotechnic protection surface is disposed in a condition of dynamic equilibrium over the entire period of action.
