  2. Exploding-bridgewire detonator - Wikipedia

    en.wikipedia.org/wiki/Exploding-bridgewire_detonator

    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 ...

  3. Detonator - Wikipedia

    en.wikipedia.org/wiki/Detonator

    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 ...

  4. Nuclear weapon design - Wikipedia

    en.wikipedia.org/wiki/Nuclear_weapon_design

    The first nuclear explosive devices provided the basic building blocks of future weapons. Pictured is the Gadget device being prepared for the Trinity nuclear test. Nuclear weapons design are physical, chemical, and engineering arrangements that cause the physics package [1] of a nuclear weapon to detonate. There are three existing basic design ...

    en.wikipedia.org/wiki/TM_31-210_Improvised...

    The TM 31-210 manual was subject to considerations regarding the repercussions of easy public access to information on the artisanal manufacturing of weapons and explosives. [ 10 ] The manual has also been mentioned in scientific literature, used as a reference for works dealing with topics such as ballistics , [ 11 ] forensic investigations ...

  6. Slapper detonator - Wikipedia

    en.wikipedia.org/wiki/Slapper_detonator

    (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.

  7. Staged detonation - Wikipedia

    en.wikipedia.org/wiki/Staged_Detonation

    A simple example is the common industrial detonator, where a very small amount of a sensitive explosive detonates, causing the less sensitive main charge of the detonator to detonate. It may involve additional steps where successively less sensitive compounds trigger a detonation wave in each other, with stages including various types of ...

  8. Exploding wire method - Wikipedia

    en.wikipedia.org/wiki/Exploding_Wire_Method

    EWM has found its most common use as a detonator, named the exploding-bridgewire detonator, for nuclear bombs. Bridgewire detonators are advantageous over chemical fuzes as the explosion is consistent and occurs only a few microseconds after the current is applied, with variation of only a few tens of nanoseconds from detonator to detonator. [7]

  9. Table of explosive detonation velocities - Wikipedia

    en.wikipedia.org/wiki/Table_of_explosive...

    The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
