Making explosives Flashcards
what are the levels of detonation for each explosive?
Primary - easily initiated
Secondary - difficult to initiate
Tertiary - very difficult to initiate
How can explosives be directly stimulated?
Electrical
mechanical (percussion) - leads to the direct explosion of low explosive propellants
Deflagration/detonation of another explosive
How can explosives be indirectly stimulated?
Magenetism
acoustic
radar
How does percussion work?
Percussion caused by localised heating upon decreased volume
the hammer compresses the voids of air, in result the gases get hot and initiate explosion
percussion can compress air to such an extent to generate sufficient heat to cause cracks in explosive material
How does stabbing work?
needle stabs explosive with very small surface area
relies on a friction based approach as needle propagates into explosive material
the needle may get bent causing a misfire
How do electrical detonators work?
