Detonation - Wikipedia

Detonation (from Latin detonare 'to thunder down/forth') is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases. The velocity of detonation in solid and liquid explosives is much higher ...


Arming with Detonating Cord - Explosives may be detonated with detonating cord. Charges are armed by taping the cap to the detonating cord or joining the cap and the cord with special connectors. The explosive end of the cap should point along the detonating cord, toward the main charge. A minimum of 25 grains per foot shall be used.

Explosive - Detonating cord | Britannica

Explosive - Explosive - Detonating cord: Detonating cord (detonating fuse) resembles safety fuse but contains a high explosive instead of black powder. The first successful one, patented in France in 1908, consisted of a lead tube, about the same diameter as safety fuse, filled with a core of TNT. It was made by filling a large tube with molten TNT that was allowed to solidify.
