The incendiary thermal effect produced by the detonation of a high or a low explosive varies greatly from one explosive to” another. In general, a low explosive will produce a longer time period of incendiary thermal effect than will a high explosive.
What are the effects of an explosion?
Explosion effects generally include those of overpressure, thermal effects, energized projectiles (fragments, debris, and missiles), ground shock, and cratering. Ground shock and cratering will not be discussed further in this paper.
What is the most powerful explosive by weight?
One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
Can air pressure cause explosions?
An explosion can be vi- sualized as a “bubble” of highly compressed air that expands until reaching equilibrium with the surrounding air. Explosive detonations create an incident blast wave, characterized by an almost instantaneous rise from atmospheric pressure to a peak overpressure.
What is the most explosive substance?
Azidoazide azide
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
What is considered a low explosive?
Low Explosives – explosives that are characterized by deflagration or a low rate of reaction and the development of low pressure. Black powder, smokeless powder, safety fuse, and squibs/igniters are classified as low explosives.
What does it feel like to be caught in an explosion?
They feel a jolting sensation that is not like anything they’ve ever experienced before in their lives. It can be much more severe than that and produce unconsciousness and damage to the body. Some of that is related to other aspects of the explosion obviously.
How fast is an explosion mph?
At 50 seconds after the explosion, when the fireball is no longer visible, the blast wave has traveled about 12 miles. It is then traveling at about 784 miles per hour, which is slightly faster than the speed of sound at sea level….Overpressure.
| Peak overpressure | Maximum Wind Speed |
|---|---|
| 10 psi | 294 mph |
| 5 psi | 163 mph |
| 2 psi | 70 mph |
Why is Semtex called Semtex?
Semtex was invented in the late 1950s by Stanislav Brebera and Radim Fukátko, chemists at VCHZ Synthesia, Czechoslovakia (now Czech Republic). The explosive is named after Semtín, a suburb of Pardubice where the mixture was first manufactured starting in 1964.
What is the most explosive fuel?
PETN. One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite.
Can explosions happen in space?
In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically ‘explode’. But as long as the explosion doesn’t require oxygen, then it will work in much the same way in space as on Earth.
What two chemicals will explode when mixed?
When you mix the two together you get sodium acetate and water. You also get carbon dioxide, which is a gas. The bag puffs up because carbon dioxide is a gas and takes up a lot of space. Eventually the bag isn’t big enough to hold all that carbon dioxide gas so it explodes!
