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.
Nitro compounds are explosive because although the diatomic form of nitrogen is very stable—that is, the triple bond that holds N 2 together is very strong, and therefore has a great deal of bond energy—the nitro compounds themselves are unstable, as the bonds between nitrogen atoms and other atoms in nitro compounds are weak by comparison.
The weakest are Hawaiian and submarine, ... The namesake of the mild explosive activity that it possesses has been active throughout historical time; essentially ...
Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.
A vehicle is packed with explosives and detonated. Cluster bomb: Over a hundred nations outlaw them now. The first one was Butterfly Bomb: Germany: General-purpose bomb: Glide bomb: Guided bomb: Improvised explosive device: Land mine: Explodes when pressure is applied to the bomb. Outlawed in 164 nations. 1832 Ming Dynasty: Laser guided bomb ...
Configured in the Davy Crockett role, the weapon contained two sets of fuzes: a radar based fuze set for a 40 feet (12 m) airburst and a capacitance based fuze set for 2 feet (0.61 m) airburst. These fuzes represented the high and low airburst modes of the weapon. The device contained 26 pounds (12 kg) of high explosives. [6]
Using explosives should help accelerate the salvage process and minimize risk to the crane operators working under tough conditions. A spokesperson for the ship’s owners said that authorities ...
PETN is a very powerful explosive material with a relative effectiveness factor of 1.66. [2] When mixed with a plasticizer, PETN forms a plastic explosive. [3] Along with RDX it is the main ingredient of Semtex. PETN is also used as a vasodilator drug to treat certain heart conditions, such as for management of angina. [4] [5]
