Open an aircraft carrier to fight against Japan

The propagation speed of stress waves in solids is much faster than that of sound waves, so when the Japanese soldiers in the bunker heard the sound of the explosion, the fragments of the stress wave avalanche had already flown there.

The fragment hit the cotton coat first, and it absorbed part of the kinetic energy of the fragment, but this was not enough to reduce the fatality of the fragment. The cotton coat was torn apart instantly, and the fragment penetrated into the flesh, and when it hit the skin, it ruptured, a large piece The fragments were broken into several small pieces, which undoubtedly increased the lethality of the fragments!

When these fragments passed through the human body, what was left was a big hole that was bloody and bloody, and the human organs inside the hole were all shattered!Those who are hit will surely die!

In order to prepare for the defense of Fengtian, the Japanese army specially purchased a large number of machine guns to ensure that each bunker has one. In this way, each bunker is a machine gun position with powerful lethality. There are five soldiers in each bunker. There are two machine gunners, who operate the machine guns in turn, two bombers, and one observer, who is used to observe large-area targets.

In this way, there is a certain overlap in the positioning of personnel, that is to say, one person may become another's human shield, so there is a good hope that although the bunker is hit by fragmentation shells, there is still a good chance of maintaining lethality.

But not all the fragments hit the person, those that did not hit the inner wall of the bunker at high speed, leaving large and small pits on the inner wall, then changed direction and continued to fly, although the speed decreased after the impact , but it is still lethal. In this way, the fragments are like weaving a death circle in the bunker, so that everyone has nowhere to escape.

Lin Yuan did not give the artillery order according to the routine, just like he commanded the artillery of the Dingwu Army before, but gave a very flexible order, that is, the commander of the artillery assigns which artillery will hit which bunker, the only one The requirement is that each bunker must be hit once.

In the area where Lin Yuan was going to attack, the Japanese army built 47 bunkers. Therefore, the Qing army specially prepared 47 observers, each responsible for a bunker, to report when the bunker was hit.

Lin Yuan waited anxiously. Fifteen minutes after the sound of the guns, the artillery commander reported that all the bunkers had been hit. Lin Yuan then ordered that the first batch of fifty cavalry be divided into five groups to attack the trenches behind the Japanese trenches.

Hearing Lin Yuan's order from the side, Wu Yuankai thought in surprise, "If this is the case, aren't there too few people? How can we win!"

But there was only one commander on the battlefield, and Wu Yuankai was not allowed to talk too much about the situation. Fifty cavalrymen jumped out and rushed towards the trench. They rushed in an arc, because if they rushed straight, they would be easily killed by their opponents!

The dispatch of the cavalry was quickly discovered by the Japanese army. Two flares rose into the sky, shining brightly in the dark night. The muzzle flames in the trenches shone like stars in the night sky. However, the effect of the rifle on the cavalry was too limited. .

At this moment, tongues of flame spewed out from several bunkers!

It turned out that the fifty cavalry ordered by Lin Yuan were the bait for these bunkers. They just wanted to scout out which bunkers were missed during the attack!

Lin Yuan made a gesture to the orderly next to him. The orderly took out a shiny bugle and blew it. When the cavalry heard this, they turned their horses and ran back.

The artillery position then started a new round of shelling, and those leaky fish who had exposed their positions were completely defeated in this round of attack!

Lin Yuan then ordered the mortars to go down and attack the position below the Japanese bunker!

Compared with the grenade of the same caliber, the body of the fragmented armor bullet is thicker, so that the fragmented armor bullet can be loaded with more explosives, not to mention that the armor fragment developed by Lin Yuan is filled with black cable Gold explosives, although made by indigenous methods, are inferior in performance to later generations of Hexokin, but their explosive power is still far superior to that of contemporary black powder and picric acid!

When Luo Chaoying presided over the manufacture of the broken armor bomb, he also added material to the Japanese on the bomb!

How did the original shell fragments come about?It all depends on the explosives installed in the warhead. These explosives blow up the shell of the shell into pieces, and the shell will produce as many fragments. Luo Chaoying applied the advanced technology of ammunition design in later generations-fragment pre-control technology.

Simply put, this technique is to use a turning tool to make some scratches on the shell of the warhead when manufacturing the warhead shell. In this way, when the explosion occurs, stress concentration will occur in these scratched places, and the shell will be damaged. The body will be broken first, which is equivalent to saving a large part of the energy of the explosion.

This technique is simple to say, but when it is used, there are many specific problems, such as the location, depth, and number of scratches. These all determine the number of fragments and the lethality of a single fragment. For artillery, Of course, it is hoped that the more fragments the better under the condition of ensuring lethality, but this is unrealistic, because there are too many scratches, the strength of the projectile body cannot be guaranteed, and the shell may disintegrate after flying into the air.

There are also a series of problems such as processing difficulty, processing time, cost, etc. It is difficult to obtain an optimal solution by mathematical methods. In fact, not only weapons and equipment, but almost all industrial system designs do not have optimal solutions. Therefore, design The choice of parameters depends on the experience of the designer, and experience is exactly what Luo Chaoying lacks most.

If the Japanese trenches were on flat ground, the pre-control shrapnel technology would be useless, because the shrapnel flew upwards. It happened that the Japanese trenches were under the bunkers, and the shells hit the trenches, and the shrapnel fell like raindrops. On top of the heads of the Japanese army!

Ten minutes later, more than 10 artillery shells had landed on the Japanese positions. Lin Yuan then ordered the artillery to stop attacking and the cavalry to attack!

For a while, the cavalry rushed towards the Japanese positions. The Japanese soldiers who were blown up by the shells were still wondering why the Chinese shells were so powerful today. When a shell exploded, the area covered by the shrapnel was almost twice the size of the original shell. At this time, when I saw the cavalry rushing up, I didn't care to think about it, so I hurriedly picked up my gun and rushed to the edge of the trench.

Humans are not machines, and it is impossible to lose no combat power because they are not killed by shrapnel and shock waves. During the shelling process, the loud sound made people's ears hurt, the pungent gunpowder smoke made people unable to breathe, and there were also bombardments falling from the sky. The clods of soil almost make people feel that they are in the end of the world. In this case, troops who lack the will to fight will run away at the sound of the enemy's cannon.

But on the ground is the Japanese army, with a strong will to fight that is rare in the world. Even though they were blown to pieces, they still raised their guns to fight back. Although the Japanese army is strong, they are facing the command of Lin Yuan and the shells carefully designed by Luo Chaoying !

The best weapon against the cavalry is the machine gun. The Japanese army watched the cavalry charge up, but the machine gun in the bunker behind them didn't make a sound at all, and they jumped up and cursed their mothers angrily.

In less than a minute, the soldiers of the Qing army rushed to the front of the trench. One Qing soldier didn't stop his horse, and with a flick of his stirrup, he jumped off his horse and aimed at a Japanese soldier. He tried to block it with his hands, but was knocked to the ground by the Qing army soldiers. He was dizzy from the fall. The Qing army soldiers drew out their knives and stabbed the Japanese soldiers under him.

The soldiers of the Qing army were like a snowball, more and more, and soon, the outer positions of the Japanese army collapsed!
