The explosive triggering sequence or the explosive train essentially consists of an 'initiator', an 'intermediary' and the 'high explosive'. For example, a match will not cause plastic explosive to explode, but it will light a fuse coupled with a blasting cap which will detonate a primary explosive that will shock a secondary high explosive and ...
Ballistic training, also known as compensatory acceleration training, [1] [2] uses exercises which accelerate a force through the entire range of motion. [ 1 ] [ 3 ] It is a form of power training which can involve throwing weights, jumping with weights, or swinging weights in order to increase explosive power. [ 4 ]
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.
The strength, or potential, of an explosive is the total work that can be performed by the gas resulting from its explosion, when expanded adiabatically from its original volume, until its pressure is reduced to atmospheric pressure and its temperature to 15°C. The potential is therefore the total quantity of heat given off at constant volume ...
RDX is often used in mixtures with other explosives and plasticizers or phlegmatizers (desensitizers); it is the explosive agent in C-4 plastic explosive and a key ingredient in Semtex. It is stable in storage and is considered one of the most energetic and brisant of the military high explosives, [2] with a relative effectiveness factor of 1.60.
Detonation cord will initiate most commercial high explosives (dynamite, gelignite, sensitised gels, etc.) but will not initiate less sensitive blasting agents like ANFO on its own. 25 to 50 grain/foot (5.3 to 10.6 g/m) detonation cord has approximately the same initiating power as a #8 blasting cap in every 2 to 4 inches (5 to 10 cm) along its ...
Small explosive charges, where the explosive's diameter is not significantly larger than its thickness, have reduced effectiveness as gas and energy are lost to the sides. [ 1 ] This loss is empirically modeled as reducing the effective explosive charge mass C to an effective value C eff which is the volume of explosives contained within a 60 ...
A mine is an explosive placed underground or underwater that explodes when disturbed, or when remotely triggered. The term originated from the use of mining to go under the enemy's city walls . Mines, unlike bombs , are placed in situ and then require some other stimulus from a target before they will detonate.
