Iniex shook his head and muttered something, he spoke in German, and the translator was not there yet, so Lin Yuan couldn't understand it at all, but Lin Yuan heard that what he said seemed to be a word, so he silently wrote down the pronunciation - Mowglisi.

Iniex checked the few ** pieces he picked up, and left the house in despair, at this time it was the noon break, Lin Yuan found a translator and asked: "What does 'Mowglisi' mean?" ”

The translator was stunned for a moment and said, "Impossible! ”

Lin Yuan asked, "What's impossible?" ”

The translator smiled helplessly and said, "I mean, the word means 'impossible'. ”

The two looked at each other and smiled, Lin Yuan knew that it was a success!

Iniex has always believed that the steel used for the 1000 mm armor has not been heat-treated, so it is relatively soft, and the shell can penetrate it, but the result of metallographic microscopy is: the steel used in the armor has been heat-treated, and the metallographic contains a large amount of pearlite, so the surface hardness of this steel plate must be very high!

This surprised Innexus, who could not imagine what kind of shell it would be able to penetrate such a thick steel plate! That's why I walked out of the city in despair.

Did Lin Yuan use any advanced weapons? Actually, no, Lin Yuan also knew that the shells fired by the 152 mm gun could not penetrate the 1000 mm high-quality steel armor no matter what, so the steel on that plate had not undergone heat treatment at all, not only that, but there was also a special treatment on that board, that is: the inside of the steel plate was empty.

Of course, the walls of the steel plates still have a certain thickness, so when they knocked on the steel plates, they did not find the patterns inside the steel plates, and where the shells hit, the gunpowder that did not burn out smoked the bullet holes to the side, and it was impossible to see that the inside was empty at all.

Strictly speaking, there must be a difference between the holes formed by penetrating solid steel plates and hollow steel plates, but the study of the destructive effect of artillery shells on targets belongs to the category of terminal ballistics, and in this era, this discipline has just started, and the difference is extremely small, almost to the point that it is difficult to detect with the naked eye, so Lin Yuan is not worried that they will see the flaws.

So where did the pieces of steel that Iniex picked up come from? During the time that Lin Yuan had asked them to wait, the people of the Beijing ship had already picked up the debris scattered on the ground and replaced them with heat-treated steel sheets, which Iniex had picked up.

After this series of elaborate design, this group of people have begun to believe in the myth of the infinite power of the Ryukyu naval guns, Lin Yuan did not directly carry out the next step, but in the afternoon, arranged a sightseeing tour for a group of foreign experts, the location of the tour is the "China and Ryukyu, Generations Connected" theme museum, the museum exhibits the edicts of the Chinese emperors to canonize the king of the Ryukyus, the tributes given by the Chinese imperial courts, etc., fully demonstrating that the Ryukyus are an inseparable part of China.

That Iniex couldn't help it for a long time, and wanted to ask how the power of the naval guns could be so great, but Lin Yuan deliberately ignored him, and when it was night, Iniex pulled an Englishman to find Lin Yuan, and the Englishman said, "We want to have a good chat with you." ”

Lin Yuan picked up a piece of paper in his hand and said with a smile: "No, according to the schedule, we will show you the 'living cloth' in a while." ”

Iniex couldn't understand Lin Yuan's words, the Englishman was confused when he heard the word "living cloth", and he didn't know how to translate it, Lin Yuan stood up and said, "It's time, let's go." Then he led them to a large room.

The room is stepped shape, very similar to a modern movie theater, the others have already taken their seats, Lin Yuan arranged the two of them, walked to the front desk, and said with a smile: "We are about to show you the latest entertainment techniques of the Ryukyus, please watch!" ”

At this time, a snow-white cloth was put down on the front desk, and then the black cloth on the window was also put down, and the room was dark, and in the highest room, a bright light was released at once, projected on the cloth at the front desk, and everyone exclaimed, but a few people whispered to the people around: "Isn't this a movie!" ”

The cloth on the stage is actually the projector screen on the Beijing ship, and the bright light behind it is the projector of the Beijing ship, the original movie has appeared at this time, Edison has already done the movie show, but the movie at this time is still in its infancy, there is no sound, no editing, and no special effects, so those people only know the principle of the Tao, and they haven't seen too many movies, and they are all watching attentively.

At this moment, a cannon appeared on the screen, and then, the other parts gradually faded away, leaving only the body tube and the firing mechanism, at this time, the body tube seemed to have been cut by a knife, and the structure inside the body tube was clearly displayed, and a cannonball was placed in the medicine room, ready to fire.

Insiders looked at the doorway, but Inix saw something strange at this time, that is, the appearance of the shell was simply too strange, that is, a slender rod, the rod was located on the axis of the barrel of the gun, and two cylinders grew out of the barrel, and the two cylinders supported the long rod in the barrel.

At this time, as soon as the firing pin moved, the cartridge spewed out a ball of fire, and the long rod flew out of the muzzle, in order to make people see clearly, so the speed of the long rod flew very slowly, and after the long rod flew out of the muzzle, the cylinder on the body slowly fell off, and after the long rod flew for a distance, it penetrated a target plate, and the movie ended.

This movie is only less than two minutes, but everyone is not surprised, because compared to the original movie, two minutes is already a feature film! At this time, the black bully was raised, oil lamps were lit on both sides of the wall, Lin Yuan walked to the front desk, and said with a smile: "The movie you see is the demonstration diagram of the firing principle of the artillery shell we used this morning, and we call it a rod armor-piercing projectile." ”

Then Lin Yuan said with a smile: "I hope the first day of the visit left a good impression on everyone, so let's have a good rest." ”

One suddenly stood up and asked in Russian: "Can you say a little more about this rod armor-piercing projectile?" ”

Lin Yuan said: "Okay, then I'll talk about it more, I believe everyone knows that the greater the kinetic energy of the shell, the stronger the ability to penetrate the armor, I don't know if you have considered it, the same kinetic energy of the shell, if the mass and speed are also the same, then what shape of the shell has the strongest armor-piercing ability?" ”

Lin Yuan saw that no one answered, and said: "An armor plate, it can be seen that the characteristics of each part are the same, so the energy required to penetrate the hole per unit volume is also the same, so the smaller the head area of the shell, the greater the depth of the hole pierced, so the shell should be made more slender." ”

"If the shell is made elongated, the caliber will be smaller, the chamber will be smaller, and the capacity of the propellant that can be loaded will also be smaller, so that the shell will not be able to reach a high speed, in order to solve this problem, we designed the following structure."

After Lin Yuan finished speaking, he made a gesture to the back, the projector was turned on again, and it was fixed on a picture, the cylinder on it was falling, Lin Yuan picked up a long rod at hand, in fact, he was more accustomed to using a laser pointer, but there was no laser generator in this era.

Lin Yuan pointed to the falling cylinder and said, "We designed this structure, which can make the outer diameter of the shell consistent with the inner diameter of the barrel, and can seal the gas produced by the propellant behind the projectile body. ”

The Russian asked, "And how did this cylinder come off after it left the barrel?" ”
