The cannonball is an absolutely dangerous commodity, so the safety device for it is also very strict.

The fuse of the shell will not be installed on it when it is transported, but it will be assembled together on the battlefield on the spot, so as to avoid the shell being detonated during transportation.

However, there are dangers.

For example, grenades use trigger fuses, and when they hit the ground, they explode, and sometimes there is a delay for better results, so what if they make a mistake?

For example, on a bumpy chariot, the gunner is carrying a shell and intends to stuff it into the chamber, at this time, the warhead must have been turned on the fuse, but at the moment when the shell is stuffed in, suddenly the hand slips, oops!

The shell fell, the warhead went down, to the floor!

What's next? Will it be immediately detonated under the impact with the ground? If this is the case, then this chariot will be shattered in a flash, and as for the people inside, they will naturally die.

In fact, you can also know that this is of course not possible.

Therefore, the shell has multiple insurance mechanisms, one of the most important things, it is called acceleration insurance, only in the gun chamber, after 500G acceleration, the insurance will be unlocked, only inside the gun chamber, there will be such a large acceleration, after all, it is 500G!

Well, this G is not a capacity, but a unit of acceleration, and on Earth, the normal gravitational acceleration is 1G, which is equivalent to the acceleration when you become 500 times your weight and then fall from the sky.

Such a huge acceleration can only be achieved inside the barrel, which also avoids an accidental explosion on the outside, and without this acceleration, it will not be unlocked.

Therefore, in those divine dramas, the sharpshooter hit the warhead of the cannonball with one shot, and then detonated the cannonball, killing how many enemies this only appeared in the divine drama, and in the real situation, it could not happen at all.

The bullet hits the primer, it's just to ignite the propellant, as long as it's not a confined space, the propellant won't explode, the bullet hits the fuse of the warhead, sorry, as long as it's not unlocked in the chamber, the shell won't explode! Want a shot to detonate a shell? Stop dreaming.

However, this is in good condition, and everything has the possibility of breaking.

If it is in good condition, no matter how you hit the shell now, as long as it does not go through the acceleration in the chamber, the fuse of the warhead should detonate.

But, in reality? It's mechanical, that is, there will be a probability of error, whoever bumps into it, who is unlucky, and now, the big guy is taking the initiative to find excitement.

No way, you have to do it!

The principle of the rejector is also very simple, that is, it is mounted on the muzzle, fixed with a claw, and then, with a screw rod turned inward, there is a warhead in front of it, and in this way, it continues to rotate, and the warhead retreats little by little under the action of this thrust, and then the entire shell is withdrawn.

The principle is as simple as that, and now, the first retractor has been installed, and several people operate it nonchalantly, once, twice, three times!

Visible to the naked eye, the claw is slowly retreating backwards, backwards, yes, it is indeed supported, but the screw thrust acts on the warhead, there is no result, but the back of the claw is pushed and deformed!

"His grandmother's, the card is really tight!"

That side has been blocked, and it doesn't move, and the screw on this side goes down hard, and it can't move the warhead over there, but it breaks the claw fixed on the muzzle here!

It's irritating.

"Another one!" Li Shuangxi shouted.

Now there is no other way but to get on the second retractor.

In the crunching sound, the screw continued to advance, and this time, the claw was fine, and you could see that the screw entered the inside of the gun chamber little by little, constantly increasing in length.

Fortunately, it seems that this time it should be fine!

"Didn't come out, didn't come out!" Xiang Zhongkai observed the shells in the turret, and there was no sign of the warhead coming out, to be exact, it was still not moving.

"His grandmother's, weird!" Liu Laozhuan said: "No, we have already screwed in, there is no reaction in there, is it?" ”

When he thought of this, he had already reacted and shouted to the big guy: "Turn the screw out!" ”

Turning in reverse, everyone was dumbfounded when the screw was pulled out.

The screw is bent!

The warhead inside does not move, and the outer jaws do not move, so the screw bends itself.

The second retractor is scrapped again.

The third and last retractor.

A few dozen meters away, a group of artillerymen stood there, nervously watching this side of the operation, their hands clenched tightly into fists, as if they were still trembling slightly, and sweat was coming out of their foreheads.

As for the few people who were working, they were even more sweaty, Liu Laozhuan had already taken off his military uniform outside, so he drooped on the barrel, wearing only a camouflage vest, took two mouthfuls, spat and foamed, and then started the third attempt.

"Click, click!" This time, as the screw was screwed in, only a few crisp sounds were heard, and the claws on this side actually cracked directly!

"His grandmother's!" Zhu Zizhong spat at the mouth: "It's all over!" ”

Besides, everything else is useless, either the screw is bent, or the claw is broken, in short, the shell is not moving in the slightest, as if it is mocking everyone.

Now, several people were already tired and out of breath, squatting there, looking at the thick barrel, with sad faces.

"How's it going?" At this moment, Liu Dajun arrived with Huang Chuanchuan and others, no matter what accidents occurred in the camp, Liu Dajun was at the forefront, and it was precisely because of this that he was able to win the love of the soldiers.

Now, when he heard that there was a malfunction here, he even threw Wang and led them down, so Liu Dajun came over directly.

If you want to continue talking, just keep talking, anyway, I can't accompany you here.

Liu Dajun came over quickly, looking at the situation at the scene, it was not optimistic.

"No, it's cold inside the barrel, and our shells are squeezed into the barrel, so we can't get out anyway." Li Shuangxi said.

"Then think of something else." Liu Dajun said: "We soldiers must constantly overcome all kinds of difficulties, and nothing can stop us from moving forward!" ”

"Why don't you ask Brother Zhenhua to come over and have a look?" Huang Chuanchuan asked on the side.

"No!" Liu Dajun replied very simply.
