Explosive devices for foxhole manufacture, demolition and urban warfare

Abstract

Explosive devices for foxhole manufacture, demolition and urban warfare. devices comprise a hollow metal cylinder; a cap at the top end closing said metal liner, said cap having a waveshaper on the interior thereof, and said cap having a hole therethrough for insertion of an ignition charge; a closure at the bottom end of said liner, said closure having the form of a liner, depressed inwardly; and an explosive composition disposed within the metal liner between the waveshaper of said cap and the depressed cone of said closure. An alternative explosive device is disclosed wherein the closure at one end of the metal cylinder is spaced apart and inwardly from the open end of said line to form a standoff space. A further explosive device is disclosed wherein additional explosive is disposed within the standoff space but leaving spaces for jet formation.

What is claimed is: 
     
       1. An explosive device for foxhole manufacture, demolition and urban warfare comprising: a hollow cylinder;   a cap closing said cylinder at the top end, said cap having a waveshaper on the interior thereof, and said cap having a hole therethrough for insertion of an ignition charge;   a closure at the bottom end of said cylinder, said closure having the form of a cone depressed internally within said hollow liner, and constituting the shaped charge liner which provides the jet;   an explosive composition disposed within said hollow cylinder between said waveshaper and said shaped charge liner.   
     
     
       2. The explosive device recited in claim 1, wherein said SC liner is spaced apart and inwardly from the bottom end of said cylinder so as to form a standoff space between said SC liner and the bottom end of said follow cylinder. 
     
     
       3. The explosive device recited in claim 2 wherein additional explosive (AX) is contained within the standoff space, starting from approximately one diameter from the base of the SC liner. 
     
     
       4. The explosive device as recited in claim 3 wherein a longitudinal axial hole is provided through said additional explosive (AX) for passage of the jet. 
     
     
       5. The explosive device as recited in claim 3 wherein the additional explosive in the standoff space is an annular ring disposed within the metal liner at the end of the standoff space. 
     
     
       6. The explosive device as recited in claim 1 wherein the liner and other corresponding parts of the SCAX has a cross-section that is either circular or square or rectangular. 
     
     
       7. The explosive device as recited in claim 1 wherein the cone of said waveshaper has an included angle of about 125° degrees. 
     
     
       8. The explosive device as recited in claim 1 wherein the cone of said SC liner has an included angle of about 110°. 
     
     
       9. The explosive device as recited in claim 1 wherein said hollow cylinder and said SC liner are metal. 
     
     
       10. The explosive device as recited in claim 1 wherein said hollow cylinder and said SC liner are aluminium. 
     
     
       11. The explosive device as recited in claim 1 wherein said SC liner has a diameter of about 3.44 inches. 
     
     
       12. The explosive device as recited in claim 1 wherein said SC liner is about 0.21 inches thick. 
     
     
       13. The explosive device as recited in claim 1 wherein the cap is acrylic. 
     
     
       14. The explosive device as recited in claim 1 wherein said waveshaper was foam and data sheet explosive.
