The article will discuss what an explosive device is, what it is for, how it appeared, varieties and applications.
A bit of history
When gunpowder was invented, it is not known exactly, there are many versions and assumptions. However, the first surviving manuscript in which there is a mention of this explosive dates from 1044 AD. Initially, gunpowder was used as a filling for fireworks and other entertainment tricks. But already at the beginning of the 12th century, it was used in cannons, and a little later an explosive device appeared. True, in modern WU it is gunpowder that is rarely used, it was replaced by more powerful substances.
According to the dictionary, this is a logistic scheme that contains a chemical explosive and means of its detonation. For obvious reasons, it is a one-time action. But what happens, what is it for and how is an explosive device made?
Army
First of all, the army needs WU. Such devices are needed mainly to destroy the enemy, equipment, buildings and sabotage.
In the armed forces as the main material for explosivedevices used TNT. Distinctive features of this substance: high power, ease of handling and, most importantly, stability. It can be dropped, beaten, even thrown into the fire, it will simply burn without any danger to others. It explodes only from detonation, in other words, from another small explosion. An explosive device based on it usually looks like a bar of TNT with an inserted fuse.
An interesting fact: during the years of the Second World War, Soviet partisans, who experienced an acute shortage of material for mines, collected unexploded shells and smelted TNT from them, which became liquid from uniform and gradual heating in a water bath.
Ministry of Emergency Situations
Another area where explosives and explosive devices are used is the Ministry of Emergency Situations. Basically, they are needed to provoke avalanches (to defuse the snow mass in advance), clearing rubble after natural disasters, or disposing of ammunition found in the ground. From old age, the latter can detonate from any impact, so sometimes you have to destroy them on the spot.
Interesting fact: sometimes the wells of an oil or gas field catch fire, and the flame, constantly fueled by a "fountain" from the bowels of the earth, is so strong that it is impossible to put it out with the usual means. Then a bomb is laid next to him, which knocks down the fire with an explosive wave. And once such a "torch" burned for three years, and they could only put it out with a nuclear landmine. It happened in 1963 in Uzbekistan.
Construction and demolitionbuildings
Some old buildings or structures are much more profitable, faster and easier to destroy with an explosion than to spend time on gradual dismantling. In this case, the energy of explosions comes to the rescue again.
Also, dynamite (an explosive based on nitroglycerin) was used at the end of the 19th century in the construction of railways and canals. They destroyed large stones and other obstacles. Currently, this method is also used.
IED
The need for such a handicraft device may be needed in different situations, for example, during hostilities. But still it is worth remembering: their manufacture is punishable by law. If you made a simple gunpowder firecracker and decided to blow it up for fun, you've already broken the law. The only explosive that can be legally purchased is smoky and smokeless powder, but only with a hunting license.
If their circulation is prohibited, then why are improvised explosive devices still used? The device so often becomes a tool for killing various terrorists and intruders. The thing is that artisanal VUs basically contain ordinary s altpeter, which is freely available. For obvious reasons, exact instructions and ratios will not be given here. S altpeter is also the main one for industrial explosives called ammonal.
Art
Not a single modern action film today is complete without chases, gunfights and explosions. To create the latter, applyvarious pyrotechnics, also containing weaker explosives. After all, such an "ammunition", an explosive device, only imitates an explosion, does not harm others.
