Device enabling the ignition of two explosive charges and warhead implementing such an ignition device

Abstract

A device enabling the ignition of at least two explosive charges using a single detonator, device wherein it comprises at least a first pyrotechnic booster that is ignited by the detonator, a first booster that firstly ignites a first explosive charge by projecting a casing onto it and which is secondly connected to a second explosive charge by at least one detonation wave transmission booster.

1 . A device enabling the ignition of at least two explosive charges using a single detonator, wherein said device comprises at least a first pyrotechnic booster that is ignited by said detonator, said first booster that firstly ignites a first explosive charge by projecting a casing onto said charge, said first booster being secondly connected to a second explosive charge by at least one detonation wave transmission booster.  
   
   
       2 . An ignition device according to  claim 1 , wherein the path of said projected casing is of a length such that the ignition of both said explosive charges is practically simultaneous.  
   
   
       3 . An ignition device according to  claim 1 , wherein said first booster is cylindrical and surrounded by said casing, also cylindrical, the projection of said casing occurring through an annular cavity arranged in said first explosive charge.  
   
   
       4 . A splinter-generating warhead implementing an ignition device according to  claim 1 , wherein said warhead comprises a block of loading explosive able to be ignited at one of its ends or the other by a first and/or second igniting explosive charge, said first igniting charge being able to be ignited by the projection of a casing surrounding said first booster and said second igniting explosive charge being able to be ignited by means of at least one detonation wave transmission booster connecting it to said first booster.  
   
   
       5 . A splinter-generating warhead according to  claim 4 , wherein said loading explosive block incorporates an axial channel inside which said detonation wave transmission relay passes.  
   
   
       6 . A splinter-generating warhead according to  claim 5 , wherein it incorporates an insulating sheath placed in said axial channel and surrounding said transmission booster.  
   
   
       7 . A splinter-generating warhead according to  claim 4 , wherein it comprises a first detonator placed so as to be able to ignite said first booster, said first detonator being activated by a priming fuse.  
   
   
       8 . A splinter-generating warhead according to  claim 7 , wherein said first igniting explosive charge may be directly ignited by a second priming means separate from said first booster.  
   
   
       9 . A splinter-generating warhead according to  claim 8 , wherein said second priming means comprise at least three detonating primers evenly spaced angularly and arranged opposite a crown of the first explosive charge.
