Add-on armor system for armored vehicles

Abstract

A multi-plate armor system used as an add-on armor in the armored vehicles, especially military vehicles. More specifically, disclosed is an armor system which, having a structure that will not be affected from impacts as well as having weight values acceptable for industry standards per unit area (kg/m2), at least two plates positioned to the armored vehicle body with a specific distance between them, allows the resulting destructive effect to be felt in the large surface with minimal damage by deflecting the impact direction of the ballistic threat such as bullets, spall etc.

1 . An add-on armor system for being positioned outside the existing armored vehicle body of an armored vehicle, especially military vehicles, the armor system comprising:
 a second plate that is made of armor steel and positioned at a certain second distance to the armored vehicle body;   a first plate that is made of armor steel with perforation structures on it and positioned at a certain first distance to the outer portion of said second plate.   
     
     
         2 . An armor system according to  claim 1 , wherein the first distance and second distance are in the range of 20-80 millimeters. 
     
     
         3 . An armor system according to  claim 1 , wherein the first distance and second distance are in the range of 25-40 millimeters. 
     
     
         4 . An armor system according to  claim 1 , and wherein the first distance and second distance are 40 millimeters. 
     
     
         5 . An armor system according  claim 1 , wherein the first distance and second distance are equal to each other. 
     
     
         6 . An armor system according to  claim 1 , wherein the thicknesses of the first plate and second plate are in the range of 2-10 millimeters. 
     
     
         7 . An armor system according to  claim 1 , and wherein the thicknesses of first plate and second plate are in the range of 3-6 millimeters. 
     
     
         8 . An armor system according to  claim 1 , wherein the thicknesses of the first plate and second plate are 4 millimeters. 
     
     
         9 . An armor system according to  claim 1 , wherein the thicknesses of the first plate and second plate are equal to each other. 
     
     
         10 . An armor system according to  claim 1 , wherein the perforations on said first plate are shaped with at least one of the forms of round, slit or elliptical. 
     
     
         11 . An armor system according to  claim 1 , wherein said perforations are round. 
     
     
         12 . An armor system according to  claim 1 , wherein gaps at the first distance and second distance are filled with air. 
     
     
         13 . An armor system according to  claim 1 , comprising a third plate associated to said second plate with a third gap containing any filler material or without this gap between them. 
     
     
         14 . An armor system according to  claim 1 , comprising two or more plates positioned with a certain interval.
