Non-initiating tandem warhead with precursor forming powder jet against explosive reactive armor

Abstract

The present invention relates to a tandem warhead including a precursor neutralizing an explosive reactive armor, which is an additional armor of tanks, without detonating it and a main warhead configured to destroy a main armor, and more particularly to a non-initiating tandem warhead with a precursor forming powder jet against the explosive reactive armor, the powder jet leaving behind no residue of the precursor jet to maximize the penetration capability of the main warhead jet.

What is claimed is: 
     
         1 . A non-initiating tandem warhead with a precursor forming a powder jet against an explosive reactive armor, comprising:
 a projectile body ( 100 ) equipped with warheads inside;   a precursor ( 200 ) disposed at the front inside the projectile body ( 100 ) to form a powder jet; and   a main warhead ( 300 ) disposed behind the precursor ( 200 ) inside the projectile body ( 100 ) to penetrate a main armor through a penetration hole created by the precursor ( 200 ).   
     
     
         2 . The non-initiating tandem warhead with a precursor forming a powder jet against an explosive reactive armor of  claim 1 , wherein the precursor ( 200 ) penetrates the main armor without detonating the explosive reactive armor ( 20 ). 
     
     
         3 . The non-initiating tandem warhead with a precursor forming a powder jet against an explosive reactive armor of  claim 1 , wherein penetration holes are created in both the explosive reactive armor and the main armor, the penetration hole in the explosive reactive armor being larger than the penetration hole in the main armor. 
     
     
         4 . The non-initiating tandem warhead with a precursor forming a powder jet against an explosive reactive armor of  claim 3 , wherein
 the penetration hole in the explosive reactive armor ( 20 ) is created by the precursor, and   the precursor may include a powder jet formation liner ( 210 ) made of metal powder and a first charge ( 220 ) applying explosive pressure towards the powder jet formation liner ( 210 )   
     
     
         5 . The non-initiating tandem warhead with a precursor against an explosive reactive armor of  claim 4 , wherein the powder jet formation liner ( 210 ) is concave towards the front of the projectile body ( 100 ). 
     
     
         6 . The non-initiating tandem warhead with a precursor against an explosive reactive armor of  claim 4 , wherein the powder jet formation liner ( 210 ) is deformed into a powder jet protruding towards the explosive reactive armor ( 20 ) by the pressure of the first charge ( 220 ). 
     
     
         7 . The non-initiating tandem warhead with a precursor of claim against an explosive reactive armor of  claim 4 , wherein the powder jet formation liner ( 210 ) is made by mixing metal powder and a binder, molding the mixture into a liner shape using powder injection molding, removing the binding using solvent and thermal degreasing technique, pre-sintering the binder-free structure to make a skeleton, and then impregnating the skeleton with a polymer-based material. 
     
     
         8 . The non-initiating tandem warhead with a main warhead against an explosive reactive armor of  claim 1 , wherein the main warhead ( 300 ) may include a main warhead liner ( 310 ) and a second charge ( 320 ). 
     
     
         9 . The non-initiating tandem warhead with a main warhead against an explosive reactive armor of  claim 8 , wherein a certain cavity is formed between the main warhead and the precursor ( 200 ). 
     
     
         10 . The non-initiating tandem warhead with a main warhead against an explosive reactive armor of  claim 8 , wherein the main warhead liner ( 310 ) is concave towards the front of the projectile body ( 100 ). 
     
     
         11 . The non-initiating tandem warhead with a main warhead against an explosive reactive armor of  claim 10 , wherein the main warhead liner ( 310 ) is deformed into a jet shape protruding towards the explosive reactive armor ( 20 ) by explosive pressure of the second charge ( 320 ). 
     
     
         12 . The non-initiating tandem warhead with a main warhead against an explosive reactive armor of  claim 8 , wherein the main warhead ( 300 ) further may include an explosive wave modulator ( 330 ) provided inside the second charge ( 320 ) to change a path of explosive pressure. 
     
     
         13 . The non-initiating tandem warhead with a main warhead against an explosive reactive armor of  claim 12 , wherein the explosive wave modulator ( 330 ) is made of either plastics or metals. 
     
     
         14 . A non-initiating tandem warhead with a precursor forming a powder jet against an explosive reactive armor, comprising:
 a projectile body ( 100 ) equipped with warheads inside;   a precursor ( 200 ) disposed at the front inside the projectile body ( 100 ); and   a main warhead ( 300 ) disposed in the rear inside the projectile body ( 100 ), wherein   both a powder jet formation liner ( 210 ) of the precursor and a main warhead liner ( 310 ) of the main warhead have a tapering shape that widens towards the front.   
     
     
         15 . A non-initiating tandem warhead with a precursor forming a powder jet against an explosive reactive armor, comprising:
 a projectile body ( 100 ) equipped with warheads inside;   a precursor ( 200 ) disposed at the front inside the projectile body ( 100 ); and   a main warhead ( 300 ) disposed in the rear inside the projectile body ( 100 ), wherein   the precursor creates a penetration hole in the explosive reactive armor by the powder jet.
