Abstract

An armor system for protecting a vehicle from a projectile, the projectile having an expected trajectory, is disclosed. The armor system has a material capable of being detonated and configured to substantially retain a shape, wherein the material leads a vehicle exterior surface relative to the expected projectile trajectory. The material has a dimensional thickness that is greater than a minimum detonation thickness of the material.

 an apparatus for mounting the module to the vehicle, the module leading a vehicle exterior surface relative to the expected projectile trajectory; 
   wherein a fill capable of being detonated is disposed in the cavity; and   wherein the dimensional thickness of the fill is greater than a minimum detonation thickness of the fill.   
     
     
         10 . The armor system of  claim 9 , wherein the fill includes substantially only nitromethane and has a 1″ dimensional thickness. 
     
     
         11 . The armor system of  claim 9 , wherein the fill includes a reactive gas. 
     
     
         12 . The armor system of  claim 9 , wherein the fill includes a liquid fuel or a liquid explosive. 
     
     
         13 . The armor system of  claim 9 , wherein the fill includes one or more of ether, ethylene, acetylene, and hydrogen. 
     
     
         14 . The armor system of  claim 9 , wherein the fill includes a mixture of one or more reactive gases and one or more nonreactive gases. 
     
     
         15 . The armor system of  claim 9 , wherein the fill includes one or more of a mixture of ether and oxygen, a mixture of ethylene and oxygen, a mixture of acetylene and oxygen, and a mixture of hydrogen and oxygen. 
     
     
         16 . The armor system of  claim 9 , wherein the first and second elements are sheet-like layers including one or more of glass, transparent ceramics, acrylic, polycarbonate, aluminum, delrin, UHMW PP, UHMW PE, and borosilicate. 
     
     
         17 . The armor system of  claim 9 , wherein the first and second elements have a thickness of about ½″ and include substantially only borosilicate. 
     
     
         18 . The armor system of  claim 9 , wherein the module is oriented at about a 45° angle from a trajectory that is substantially perpendicular to a vehicle exterior surface. 
     
     
         19 . The armor system of  claim 9 , wherein each of the first and second elements include a plurality of glass sheets having a thickness of about ⅛″.
