What is a thermo-weapon?

Explosive heat bombs cause a series of turbulence waves with longer duration and much greater strength than other solid explosives.

What is thermal weapon?

A thermonuclear weapon is a series of explosive weapons that , when exploded, can generate a lot of shock waves, long and larger than other explosive weapons using other conventional solid explosives. It is very useful in military because of its ability to deal high damage as well as to destroy certain fortifications, or lightly armored vehicles that would normally have to use specialized weapons for damage or destruction. . It is compared to a tactical atomic weapon but does not emit radiation.

Principle of operation of thermo-weapons

A trial of a thermonuclear bomb.

The operating principle of this weapon is to use shock waves that converge into one point to create the highest power . The flame created by burning fuel will cause the air to expand suddenly to create these shock waves. It is this flame that creates great damage due to its temperature radiating around and drawing all the air into the flame to form a short-lived vacuum that affects all organisms around the crop. Exploding and draining oxygen to cause all creatures to suffocate even lead to death.

The effectiveness of this weapon depends very much on the amount of oxygen in the air where it is used , normally the explosive compound of this weapon has a mixture of oxygen (standard 15% explosive and 75% oxygen). ). When compared to the same amount of thermonuclear weapons, it is much more powerful than other normal solid explosives. However, due to the disadvantages that depend on oxygen in the area around the target, it is completely unsuitable for underwater use, high combat or bad weather. However, it has a huge advantage in deploying to attack narrow environments such as tunnels, caves or squares.

Because these environments provide good protection for conventional explosive weapons. But for a narrow environment thermocouple weapon it will help focus the shock and heat waves more effectively, when it withdraws vacuum, in a narrow and closed environment, it will be very difficult to replace the source of air. causing all organisms in the environment to be overwhelmed and unbalanced by pressure for too long.

It is commonly used by many countries around the world. This weapon is very effective for combat in urban environments and other complex terrains when it can create a fire effect on a vast environment that destroys surrounding infantry and the pressure it causes. can focus on destroying very strong in a very small range to minimize physical damage when needed, while other weapons often destroy facilities on a very wide range to be able to close equivalent trade.

The most powerful thermonuclear bomb ever tested is the Father of Russian-made bombs with a four-times stronger explosion than the mother of the US-made bombs .

Other weapons included in this group are : high-pressure impulse weapons, heat and pressure weapons, vacuum-drop bombs and combustible cluster bombs.

Operation of thermo-weapons

The thermonuclear weapon before exploding will release its fuel around to form a highly flammable cloud (often shaped like a parachute so that the shock wave when created will focus on the target to be destroyed. ). Is the spraying of a large range of fuel also increasing the impact due to the large explosion range as well as the level of heat damage that it creates on a wide range of weapons that normal solid-explosive weapons can do it.

The effectiveness of this weapon depends on many factors such as the rate of explosives dispersing into the air, the structure of the explosive cloud, the wind flow can change the shape of the cloud, the ability to absorb it. ambient air, ignition time from fuel dispersion. In some designs to have the highest strength, the explosive mixture is cooled so that it can spread more widely before it can catch fire.

For the fuel cloud there will be two cases that will make it useless: the ratio of dispersed fuel is too wide, leading to the fact that the ratio of fuel in the air below the permitted level makes it impossible to ignite and The ratio of fuel in an overly dense area makes it not enough oxygen to catch fire. For gasoline vapor, for example, the ratio of 1.3 to 6.0% in one area can catch fire and with methane the ratio is 5 to 15%. Other parameters contribute to the danger of fuel clouds such as the dispersion and the type of fuel it is formed, the power of the ignition source, the natural conditions when the cloud is formed and the structure of cloud.

Pressure in the explosion can reach 430 lbf / in² (3 MPa, 30 bar) and the temperature can reach from 4500 to 5400 ° F (2500 to 3000 ° C). Shockwaves outside the explosion can move at 2 mi / s (3 km / s). After the initial explosion, creating shockwaves, heat and high pressure damage will result in the withdrawal of air into the fire, causing the surroundings of the explosion to be almost vacuum, causing all organisms around. it suffers from suffocation and sudden pressure imbalance.

It is the withdrawal of this atmosphere that the fire will draw unburnt fuel particles of the fuel cloud back to the fire where they will ignite later when more oxygen maintains the fire of the explosion and heat emission. long. The phenomenon of asphyxiation and injury can still happen to all organisms far from the main explosion, especially when it occurs in narrow environments such as tunnels or caves where the explosion can drain almost entirely. The air in the enclosed space and the heat and pressure of it spread very far in this environment.

Modern thermonuclear weapons often use chemical reactions to activate ignition rather than using ignition or waiting for the fuel cloud to throw and throw fire or shoot. Sensitive substances and thermal reactions to air are mixed into explosive fuel (eg AlH3) depending on the size of the particles whose fire activation time will vary: With a particle size of 315 μm it will have an Slow response and heating, and at 5 μm, it will react immediately when exposed to air and maintain the flame for 40 ms. Aluminum powder is mixed into an explosive compound to produce high heat because it reacts to fire and produces very strong heat when a fire activates.
