Modular protection system for critical assets and infrastructure

Abstract

A modular system for protecting a critical asset includes a plurality of vertical members extending vertically upwardly from a ground surface, and inner and outer stacks of spaced-apart horizontal members connected between adjacent pairs of the vertical members defining a vertical wall. The spaced-apart horizontal members have cross sections and spacings such that no line can be drawn through the wall without intersecting with one or both of the inner and outer stacks. The cross sections of the horizontal members in both stacks include elongated angled surfaces such that projectile on a trajectory toward the critical asset is deflected upwardly or downwardly and away from the critical asset. In a preferred embodiment, the horizontal members are angle irons. In a more preferred embodiment the horizontal members are 1/2″ 90-degree steel angle irons oriented sideways, such that the elongated plates making up the angle irons are 45 degrees off horizontal.

1 . A system for protecting a critical asset on a ground surface, comprising:
 a plurality of vertical members extending vertically upwardly from the ground surface;   inner and outer stacks of spaced-apart horizontal members connected between adjacent pairs of the vertical members defining a vertical wall;   wherein the spaced-apart horizontal members have cross sections and spacings such that no line can be drawn through the wall without intersecting with one or both of the inner and outer stacks; and   wherein the cross sections of the horizontal members in both stacks include elongated angled surfaces such that projectile on a trajectory toward the critical asset is deflected upwardly or downwardly and away from the critical asset.   
     
     
         2 . The system of  claim 1 , wherein the horizontal members are angle irons. 
     
     
         3 . The system of  claim 1 , wherein the horizontal members are angle irons having a thickness in the range of from ¼ to 1 inch. 
     
     
         4 . The system of  claim 1 , wherein the horizontal members are angle irons having a thickness of substantially ½ inch. 
     
     
         5 . The system of  claim 1 , wherein:
 the horizontal members comprise two strips of metal intersecting at an angle defining a V-shaped cross section and an elongated common edge; and   wherein the common edges of the horizontal members in both of the stacks are oriented outwardly away from the wall.   
     
     
         6 . The system of  claim 5 , wherein the horizontal members are 90 degree angle irons oriented sideways, such that the strips of metal making up the angle irons are 45 degrees off horizontal.
