a small amount of a more powerful secondary explosive, directly in contact with the primary, and called "base" or "output" explosive, able to carry out the detonation through the casing of the detonator to the main explosive device to activate it. Explosives commonly used as primary in detonators include lead azide, lead styphnate, tetryl, and ...
The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
(A) Slapper detonator's pellet or flyer impacts a wider area of surface on the explosive output charge, and even though energy is lost to the sides of the area impacted, a cone of explosive is efficiently compressed. (B) EBW detonators only initiate a single point, and energy is lost in all directions, making the energy transfer less efficient.
The resistive heating vaporizes the wire, and an electric arc through that vapor creates an explosive shockwave. Exploding wires are used as detonators for explosives, as momentary high intensity light sources, and in the production of metal nanoparticles.
Detonating cord (also called detonation cord, detacord, detcord, blasting rope, or primer cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6,400 m/s (21,000 ft/s), any common length of detonation cord appears to explode instantaneously.
The US Army vet rigged the explosives with makeshift remote detonators he put together from readily available materials, including electric matches, or “hobby switches.” ...
President Biden says the New Orleans attacker acted alone, and had a remote detonator for explosives before driving a pickup truck into a crowd of people, killing 14 and injuring 35 on New Year's Day.
These are the Microdet electric detonator, the explosive lead, the explosive booster, and the delay primer assembly functioning as follows: [1] In the PROX, NSB, and IMP fuze settings, a firing circuit applies a voltage to the small Microdet which faces and ignites a bigger explosive lead that channels into the explosive booster which initiates ...
