Device and Method of Using Explosives to Breech a Surface

Abstract

An explosive device used to breech a surface is disclosed. The device comprises a backing, a detonation cord secured to the backing and a shock tube. The detonation cord is arranged along the backing of the device and extends beyond the backing at at least one point of extension. The device comprises a shock tube with cap detonator, wherein the cap detonator is connected to the detonation cord at at least one point of extension. An igniter is attached to the opposite end of the shock tube. A method for breeching a surface is also disclosed.

1 . An explosive device used to breech a surface comprising:
 a) a backing;   b) a detonation cord secured to the backing, wherein the detonation cord is arranged along the backing and extends beyond the backing at at least one point of extension; and   c) a shock tube with cap detonator, wherein the cap detonator is connected to the detonation cord at at least one point of extension, wherein an igniter is attached to the opposite end of the shock tube.   
     
     
         2 . The device of  claim 1 , wherein the device is bi-fold comprising two sections of backing and one hinge. 
     
     
         3 . The device of  claim 1 , wherein the device is tri-fold comprising three sections of backing and two hinges. 
     
     
         4 . The device of  claim 1 , wherein device  1  comprises an adhesive used to secure the device to the surface. 
     
     
         5 . The device of  claim 1 , wherein device  1  comprises a handle. 
     
     
         6 . The device of  claim 5 , wherein the handle is configured to allow placement of the device on the surface from a distance. 
     
     
         7 . The device of  claim 1 , wherein the device comprises an absorbent material which secures the device to the surface. 
     
     
         8 . A method for breeching a surface comprising:
 a) securing a device to a surface, wherein the device comprises a backing and a detonation cord secured to the backing, wherein the detonation cord is arranged along the backing and extends beyond the backing at at least one point of extension, and a shock tube with cap detonator connected to the detonation cord at at least one point of extension, wherein an igniter is attached to the opposite end of the shock tube;   b) extending the shock tube to a desired length; and   c) igniting the shock tube.   
     
     
         9 . The method of  claim 8 , wherein the device is bi-fold comprising two sections of backing on one hinge. 
     
     
         10 . The method of  claim 8 , wherein the device is tri-fold comprising three sections of backing and two hinges. 
     
     
         11 . The method of  claim 8 , wherein the device comprises an adhesive used to secure the device to a surface. 
     
     
         12 . The method of  claim 8 , wherein the device comprises a handle. 
     
     
         13 . The method of  claim 12 , wherein the handle is configured to allow placement of the device on the surface from a distance. 
     
     
         14 . The method of  claim 8 , wherein the device comprises an absorbent material which secures the device to the surface.
