Like throwing grenades into tanks and gun barrels in film and television dramas, can it really destroy tanks?

How can I put it? Can make the tank useless, but not destroyed. At best, it is to blow up the gun of the tank, because the insurance of the shells in the tank was not lifted before launch, and later, in order to prevent the shells from exploding inside the tank, the shells will be desensitized, so it is difficult for ordinary grenades to detonate the shells, and naturally it is impossible to destroy the tank.

So under what circumstances can it be detonated? The first one is that when you throw the Grenade in, the tank has just been loaded with shells and is about to launch. This means that the insurance of shells will be automatically lifted, and grenades can destroy tanks by detonating shells.

The other is to throw two grenades into the barrel in a very short time. The first explosion will release the safety of the shell, and the second will detonate, but the probability of these two situations is known to everyone.

In addition, modern warfare pays attention to the coordination of steps and tanks, and a tank is often accompanied by several chariots. Therefore, throwing grenades into the barrel at close range even became a joke. If it is a long-distance bombing, even a Buddhist marksmanship is not as good.

We don't discuss the practical operability of the anti-tank tactic of throwing grenades into the barrel of a tank. In theory, grenades can indeed be thrown into the barrel of a tank, because the diameter of grenades is generally about 60 mm, while the caliber of modern tanks is generally above 100mm, and grenades can be thrown into the barrel of a tank. But even if a Grenade is thrown into the barrel of a tank, can it really destroy the tank? Obviously not!

The gun of a tank can be sealed, and its breech is not only firm but also completely sealed. As long as the loader of the tank closes the breech, it is impossible for grenades to enter the tank, causing casualties to the tank crew or detonating the ammunition of the tank mine. Even for a tank gun with an automatic loader, there is a separation distance between the loader and the hole. Unless the Grenade can blast the hole, it can only detonate the shells in the loader. Obviously grenades can't have such power. Grenade can only blow up the barrel of the tank at best.

Grenade's killing mainly depends on the shock wave formed by explosion and the fragments ejected around it, which has a strong effect on soft targets and is too weak on steel targets such as armor. The charge of grenades is generally below 300 grams, and the pressure of shock wave produced by explosion is about 45-80 kPa. Tank guns are generally made of high-quality alloy steel, and the inner wall of the gun tube can withstand 500-800 MPa, which is completely out of the order of magnitude. In other words, the explosion of grenades in the barrel will hardly have any impact on the barrel, let alone the damage to the barrel in the tank.

On the other hand, even if a Grenade is thrown into the barrel of a tank, the tank gun will burst and cannot be used. Does this really achieve the purpose of destroying the tank? Tanks are not only a weapon of tank guns, but also machine guns. Tanks have at least two machine guns, while modern tanks generally have three machine guns and an anti-aircraft machine gun. These three machine guns are also very powerful, which can easily suppress the other infantry, and the threat is still great. Moreover, it is difficult to throw grenades into the tank itself. It is almost impossible for infantry to throw grenades into the barrel of a tank until they rush to the side of the tank. Under the cover of tank machine gun fire, it is almost impossible for infantry to rush to such a close distance unless the tank cannot move and is isolated on the battlefield.

At the beginning of World War II, when the Germans were dealing with the Soviet heavy KV-2 tanks, German soldiers tried to throw grenades into the barrels of KV tanks to destroy them. At that time, the Soviet KV-2 crawler had been destroyed by the Germans, and the German infantry detoured to the Soviet tanks from the flank and rear, but the tank guns were too high and the turrets turned back and forth, which made it impossible for German soldiers to climb the tanks. The parallel machine guns of tank turrets pose a serious threat to the Germans. Finally, the German infantry failed to put grenades into the tank guns, which shows that this tactic is in practice.

It can only be said that it is very difficult and the probability is extremely small. So it's a dramatic plot. If you want to blow up the tank by throwing grenades along the barrel, unless the tank has just been loaded at this time. Because the tank only opens the bolt when it is loaded, the barrel and turret are connected at this time. The bolt used in tank gun is mainly wedge bolt, and the bolt body is as thick as armor block. Just a Grenade, dozens of grams of explosives, can you blow up the bolt?

Soviet tank guns generally use cross wedge bolts.

The body of the gun is such a thick iron block that it is impossible to expect the Grenade to blow through.

Even if a high-explosive bomb is stuffed in the gun chamber at this time, it may not be able to detonate. Because the impact fuse of the shell is insured. When the safety is not released, the pin in the fuse cannot touch the fire cap no matter how it moves. The fuze used in collision fuze is generally inertial release, that is, the fuze is released by using the inertial force generated at the moment of projectile launching, but it takes some time, which ensures that the projectile can detonate at a certain distance after it is ejected from the barrel. If it is a time fuse, it is even more impossible to detonate, because the time fuse, like a mechanical watch, is released by inertial force and can only be triggered if it reaches a specific scale. The fuse contains a detonator, so as long as it is not excited, the explosive itself is difficult to detonate. So grenades are extremely difficult to detonate shells. But the barrel of the gun was really blown up by a Grenade, so the crew must be calm and don't slide the tank gun by hand. At this time, the barrel is full of shrapnel, which is easy to cause an explosion.

The power of grenades tickles modern tank guns. The barrel of modern tanks adopts chrome plating and self-tightening technology in the inner bore, which has stronger and stronger resistance to chamber pressure, and the pressure generated by Grenade explosion is too small. However, the debris is troublesome, which may leave a mark on the inner cavity or make the chrome-plated layer fall off, thus greatly reducing the service life.

The design bore pressure of 130mm gun developed by Rheinmetall Company of Germany reached 880MPa. Throw a Grenade in. It's nothing.

Throwing grenades into the barrel of a tank can definitely blow up the main gun of the tank, but it is absolutely impossible to blow up the whole tank, because the gun can be sealed, and the tail of the gun is not only strong but also sealed. Only when the loader closes the gun bore at the back can grenades enter tanks or important parts. Even for tank guns using loaders, there is an isolation distance between the loader and the gun bore. The Grenade that explodes in the gun chamber will not detonate the ammunition in the loader, but only blow up the gun at most.

Artillery is actually a very fragile thing. Anyone who has seen World War II movies has seen such a picture. A little obstruction at the muzzle of the main gun can detonate the fuse of the shell, thus detonating the high-explosive shell before the shell leaves the barrel, and there will be an explosion. If the blockage is strong, even if the tank fires an "armor-piercing bullet", the explosive force of the deposited high-pressure air can tear up the barrel. Of course, if the barrier is not strong, the armor-piercing projectile can still be shot.

The basis for judging whether the tank is destroyed is that the tank members abandon the car or can't fight any more. Obviously, modern tanks generally have three machine guns, which can ensure that tank members continue to fight after the barrel explosion. Even some experienced armored soldiers can lengthen the tanks and fight with light weapons. Such a tank is still a mobile fortress and cannot be said to have been destroyed. Moreover, it is difficult to put grenades into the barrel in actual combat.

As early as World War II, soldiers who used anti-tank weapons at close range were warriors who survived, but in the information war, infantry had almost no chance to get close to tanks. Even if the Grenade is put into the barrel of a tank, it is impossible for the Grenade to slide into the barrel by virtue of the installation height of the gun, and the other barrel can be used to continue fighting. Therefore, putting a hand mine into the barrel can't destroy the tank, but at most it will cause general damage by blowing up the barrel.

Sure！

It is not impossible, but the probability is very low, which is basically an impossible goal.

First, the tank should be filled with grenades, and secondly, it should be bombed twice with two grenades.

First of all, the Grenade installed in Tanqueray will have an insurance mechanism to ensure that the Grenade will not explode in the barrel when it is launched. This insurance mechanism will cancel the insurance because the rear seat accelerates when firing. So that the Grenade can explode as soon as it touches the target.

First, put a Grenade in Tanqueray with a Grenade. When the Grenade explodes, it is the same as firing, and the fuse safety of the Grenade will be unlocked.

After the fuse of the Grenade is unlocked, put another Grenade in it. After the Grenade explodes, it will directly detonate the fuse of the Grenade, and then the Grenade explodes, causing the tank to explode.

Only a few people can do it. But a video of W Jun did record the process of the tank being blown up by grenades.

The guerrillas crept up on the tank and stuffed a Grenade into the barrel.

The first explosion of a Grenade

The guerrillas went to plug grenades again.

A Grenade stuffed into a tank

The explosion detonated the Grenade in the tank, and the tank burst into flames, killing all the internal members.

Because W Jun hates reading with a video repeatedly, readers who are interested in watching the whole video can look at W Jun's previous answers. The question answered at that time was "Can grenades be thrown into the barrel of a tank to blow it up? "/Question /6539643029270036739/

It's hard to destroy or even blow up the barrel. The key question is how to get up. Similar to the anti-Japanese drama, the 37mm cannon and Grenade of the Japanese bean chariot can blow up the barrel, but the problem is that the barrel of this gun can't be stuffed with grenades at all. Grenade is generally at least 50 mm in diameter. In most cases, it is difficult to bomb tanks with grenades.

The artillery of the tank is sealed, and the inside of the tank cannot be seen through the muzzle. If you can see the inside of the tank through the muzzle, the Grenade can slide into the tank along the barrel and kill the tank hand, even if the tank is killed. The tail of the barrel is sealed, so there is no way to throw grenades into the tanker.

Moreover, the most important thing is that the damage of this kind of Grenade to the tank barrel is really limited. Take the tiger tank as an example. The caliber of the tiger main gun is 88 mm. Think about it. Can a barrel that can fire 88 mm shells be afraid of a small Grenade? Grenade mainly relies on fragments, which can hurt people, but it is basically ineffective against tanks. Tank shells, with a charge of several kilograms, and grenades with a charge of dozens of grams, are not a heavyweight at all.

The key question is, how to get up there? The tank itself carries self-defense machine guns and coaxial machine guns. If it is close, it is a sieve. And tanks usually support infantry, and a large group of people around them are actually protecting tanks. It's really hard to get close to the tank. Go up and swing?

Infantry fight tanks, mainly attacking the engines and tracks of tanks and destroying their power. Now even RPG rocket launchers can't handle tanks, let alone small grenades.

A drama is a drama after all! If a Grenade can rush to destroy a tank, then this is definitely a direction for the director in the future, because in previous dramas, only dozens of people could protect it, and then one person and one dog escorted it on the battlefield. The bullet won't hit, and even the hair won't be messy. Then, put the explosive charge under the tank and blow up the whole tank team. This is a great play, a perfect screenwriter, but the play is often ignored. It is the tank that not only fires shells, but also has machine gunners on it. As long as you are close, it is meat buns that beat dogs. If you go there, you can't get close at all. However, it once again proves that the myth of the play is that the sniper will directly kill the gunman, and the plot is so perfect.

In fact, this question is the same as whether a sniper will blow up a tank gun with a large caliber sniper rifle. Compared with these two, grenades are more powerful, because the shock wave and shrapnel of grenades are more fierce, so Grenade sniper rifles are more powerful. Does that mean grenades can blow up tank guns? This is the gap between ideal and reality. If you want to know whether it can be blown up, you should compare the power of grenades with the hardness and endurance of tank bore.

If it is an ordinary Grenade, its power is that the explosion radius is not that big, generally within 5 meters. Now the Grenade is within 10 meter, but the lethality of the Grenade with forged fragments is 15 meter. In these three shooting ranges, people standing can only become a sieve, and shrapnel is all over their faces, and people will be affected if they are so close. Just like some words, doors and walls are scared, so its power is not small. In the past, we saw someone robbing a tomb and blowing it up when it came out of the hole. This is a hand grenade with close range power.

At present, the caliber of the tank barrel is 125mm, so grenades can be placed in the barrel. First of all, the first condition is established. Then, if a Grenade is put in and explodes, can it really explode? The answer is no. First of all, the structure of the bolt is difficult to be destroyed, and it is difficult to affect this part with grenades. And the bearing capacity of the gun bore is really strong. The impact and power of artillery shells on the gun bore are mostly nothing compared with the power of grenades, and the power of grenades is compared with this power.

Many people will have a doubt, that is, when the Grenade explodes, can the tank shells perish together with the Grenade and then blow up the gun bore! The shell will explode because it is detonated by a strong external force, but the Grenade explosion may affect the launch of the shell. Is it because there are too many shrapnel and steel balls in the Grenade that when it gets stuck, it can't achieve the expected effect? But reality throws water on our heads, because we completely ignore the powerful impact of tank shells. These shrapnel and steel balls are of little use.

Finally, it is difficult for people to put grenades into the gun bore of tanks. First of all, the gun bore of the tank is very high and inclined. So if people throw it in, they need to calculate the throwing arc and the flexibility of their hands. This is similar to basketball. The angle is good, but the feel is poor. And luck, bad luck, can't throw it in, just throw it once and don't go in, brush it with a basketball and come out again.

In fact, throwing grenades into the barrel of a tank can destroy the structure of the barrel, thus making the tank lose its main attack ability, but it is difficult to destroy the tank directly. You have to say that you can detonate the tank shells in the gun barrel through grenades, which will lead to martyrdom and destroy the tanks. That luck and probability are much more difficult than just buying a lottery ticket and winning a hundred million prizes! In the real battlefield, unless there is a rare opportunity, or a brain-dead person is crazy, it is possible to stuff grenades into the barrel of a tank. No matter how thick the muzzle is, it depends on how long you can live!

Compared with tanks, the effective destructive power of hand grenades, a single-soldier light explosive weapon, is that throwing them into the engine compartment of tanks, rather than stuffing them into the barrel of tanks, can play an effective attack role. If you put a Grenade into the barrel 10,000 times, it is better to throw a Grenade or a burning bottle into the engine compartment or turret compartment of the tank, which is easier to destroy a tank. Moreover, these methods of Grenade attack on tanks have been successfully destroyed in World War I and World War II, or the tanks have lost their combat capability, which is truly recognized as an effective means to deal with tanks. Thanks to the friends who asked questions, asking this special question made me get it off my chest! )

Let's talk about the launching mechanism of tank guns: warhead and propellant. First, put the warhead into the gun bore, then calculate how much propellant is needed according to the target, then put the modular propellant, add the propellant fuze to stimulate the launch for a certain distance, and then unlock the fuze, trigger, or close the explosion. This is a security mechanism to ensure that it will not hurt itself. Therefore, throwing a Grenade into the gun bore will not detonate the warhead, and the explosive power is not as good as the explosive pressure of the propellant that fired the shell. Even though the action of the propellant is mostly at the bottom of the projectile, the pressure at the top of the projectile is still not less than the pressure when the Grenade is launched. Therefore, at most, the mine will destroy the gun bore and will not detonate the inside as shown on TV.

Theoretically, it is possible to destroy the main battle tank. For example, when dropping the bomb, the bolt of the tank gun happened to be not closed, and the tank gun appeared a certain elevation angle. Grenades or grenades fall down the gun bore by inertia or gravity, and fall into the tank war room. The commander, gunner and loader are reimbursed, and the electronic equipment or sight-seeing equipment in the turret is blown up, causing the tank ammunition to have no protective measures, resulting in secondary effects, and the tank is completely reimbursed. Or there happened to be an unexploded Grenade or other chemical bomb in the gun hall, and a collision fuse was just installed, which directly detonated and caused an explosion in the bore, and the tank was finished. However, the power of grenades or fragments of grenades will damage the rifling of rifled guns or the wall of muskets to some extent, which will lead to the explosion of tanks when firing ammunition. This kind of scene is more common in domestic dramas or movies about World War II in Europe and America. In fact, when there are many ways to deal with local tanks on the battlefield, no one will risk throwing grenades or grenades into the gun bore.
