Since its birth, the iron lump of tanks has been to gallop across the battlefield and is invincible. In order to prevent the enemy's attack, it has thick armor, and in order to penetrate it, the enemy is constantly developing new armor-piercing.
The technology, as if it were snowballs, the thickness of the tank's armor was constantly strengthening.
At the beginning, the thickness of the tank's armor was only a few millimeters or more than ten millimeters. By the end of World War II, the thickest part of the tank's armor had begun to develop towards 200 millimeters.
However, increasing the protection force alone cannot completely solve the problem. The thicker the armor, the heavier the weight will be. It is not just a problem with a diesel engine that requires a larger horsepower, but a bridge that the tank needs to pass along the way.
Even the road surface can't bear it.
During World War II, Germany created a rat tank, which sounded very powerful, but it needed constant help from engineers along the way, but in fact it no longer had the mobility that the tank should have.
At the same time, the continuous improvement and improvement of various other anti-armor technologies has made it useless to simply increase the thickness of the armor. Take the armor-breaking bullets as an example. Without penetration, the armor behind the tank will be destroyed.
Can destroy tanks.
Therefore, we need to find new ways to protect the armor.
The first to use is naturally the technology of composite armor. By setting up a sandwich structure, adding armor of different materials, stacking them layer by layer, which has the effect of one plus one being greater than two.
And this explosion reaction armor has actually existed for a long time.
The Soviet experts who initially proposed the concept of "reactive armor" began to try it in 1949, but they failed after several experiments and finally gave up their research.
Among them, the biggest problem is insensitivity explosives.
When the anti-armored ammunition flew over, it first hit the explosion reaction armor. At this time, the insensitive explosives, that is, inert explosives, are detonated, the shock waves generated by the explosion, and the reaction armor decks.
The resulting fragments will interfere with and destroy these anti-tank ammunition, thereby reducing their ability to penetrate the armor, thereby protecting the occupants in the vehicle.
For example, when an RPG comes, it depends on a metal jet. If the metal jet wants to drill into it, at this time, the explosive jet produced by the explosive armor will offset the effect of the metal jet.
As for the armor-piercing bomb, after coming, this armor block is not enough to blow it up, but at least it can change its flight direction and even fly out of the surface of the tank like a water raft.
If you look at the tanks in later generations, many tanks will cover the surface of brick-like things. This is explosion reaction armor. It exists as an additional layer of protection for tank armor, improving the protection effect of the tank.
However, it also has other challenges. For example, on the battlefield, bullets are not eye-catching and bullets flying everywhere may also hit this reaction armor block.
At this time, if this reaction armor block is detonated by a bullet or shrapnel, it will lose its effect. After all, this thing is a one-time thing. After going to the battlefield once, it will be fine if it breaks and changes wherever it is broken, but
On the battlefield, when a charge was just over, his reaction armor block was blown up by someone's machine gun, and it would lose its effect.
Therefore, it needs to detonate when armor-piercing shells, armor-piercing shells and other shells come. At the same time, other ammunition, bullets, and shell fragments cannot detonate, and they must selectively explode. This blunt explosive is a difficult point.
It's right.
The Soviets gave up because they couldn't find a suitable recipe.
However, the others persisted, for example, Israel, this country has begun constant wars since its founding, and one of their central ideas is to put people first, because they cannot fight the tactics of the sea of people, their
The life of every soldier is precious.
Therefore, all Israel's weapons exist to protect people, and to the extreme, take Israel's main battle tanks as an example, put the engine in front.
This is simply the only one in the world. What is the engine in front? At critical moments, the engine is also used as armor, which can better protect the tank hands. Reactive armor, a means that can increase armor protection, can increase armor protection
, They naturally conducted continuous research, improved the design, and even applied it to their own tanks.
They added protection to their old tanks, and placed these reactive armor blocks on them.
"Explosion reaction armor can use a sandwich biscuit-like structure." Qin Zhenhua began to introduce this structure. In fact, it was first proposed by the Germans. The structure is not a difficult problem and there is no need to be kept secret. It is like the British saying that they are themselves
The Chobam armor is like ceramic armor. So what if you say it, who can imitate it? It is impossible to imitate it in front of you.
"The outermost is a steel panel, and thus the inert explosive layer and inert material layer are the innermost part of the main armor is another steel back plate, which together form a large piece of bread." At this time, Qin Zhenhua was not prepared.
Good slideshow, so, while saying, picking up the book beside you to demonstrate: "In this way, when hit by anti-armor ammunition, the inert explosive inside will be lured. The shock wave generated by the explosion and the reaction armor
The fragments generated by the deck will interfere with and destroy these anti-tank ammunition, thereby reducing their ability to penetrate armor, thereby protecting the occupants in the vehicle.”
It is precisely because of the different anti-armor capabilities that when talking about the protection of a tank, I will never simply say how thick its steel plate is, but how thick its equivalent protection ability is.
In terms of equivalent protection capabilities, it is also divided into different equivalent protection capabilities for armor-piercing bombs and armor-piercing bombs.
Different mechanisms, the final effect is different.
"This kind of explosion-reactive armor has many advantages and of course there are also disadvantages, so we need to consider the application comprehensively. Now, I will introduce to you the advantages and disadvantages of this armor."
Everyone sounded seriously.
Although all the experts here are, the fields of research are different. It can be said that so far, no one has studied explosive reaction armor. Even if the experts present have armor, they mainly study composite armor.
After all, I haven’t seen any practical effect of explosion reaction armor yet, and it has not attracted much attention yet.
