Daming Military Empire

Chapter 662 Steel Behemoth, Invincible Battleship
Don't wait, the young man's head is white, empty and sad.

There are many people in this world, because of one or another reason, they are sad, sink, give up on themselves, and after a long time, they still achieve nothing. Apart from lamenting the injustice of fate, there is nothing left but sadness.

Zhu Cijiong didn't indulge in sadness, after all, it was just a memory of his previous life. In this life, Ming Dynasty didn't die, and Ming Dynasty was rising strongly, and he needed to work hard to win the supremacy of the sea in one fell swoop.

He will not moan and sigh all day long, do not think about making progress, and slowly wait for the great powers to surpass, when the time comes, he will be sad.

Now, with iron-clad warships, the Ming Dynasty Navy must be invincible. Of course, the premise is that they must be built first.

The next day, after the early court, he summoned Bi Maokang, Sun Yuanhua, Wang Zheng, Song Yingxing, Xu Fuyuan, and Xia Yunyi, several technical backbones, to hold an imperial meeting to discuss the production of iron-clad warships.

As soon as these people gathered in the small meeting room of the Qianqing Palace, they knew that the emperor had something new to tell them to do.

Sure enough, as soon as Zhu Cijiong came in, after a few salutes from the monarchs and ministers, he said directly: "Everyone, I invited you here today mainly to discuss the issue of iron-clad warships, that is, to cover the outer surface of the warships with a layer of iron plates. In this way, not only It is difficult for the shells to damage the battleship, and the battleship itself can be used as a weapon to hit the enemy's warship. Facing the wooden battleship, the iron-clad battleship is bound to be invincible!"

When everyone heard the words, some were dumbfounded, some were inexplicably surprised, some were thoughtful, with different expressions and reactions.

It is not that no one has thought about the issue of covering the outside of a battleship with iron plates, but it is not a very simple matter, because iron plates are quite heavy. If the entire battleship is covered with a layer of iron plates, the weight will be reduced. It's so big that it's frighteningly large. According to the size of a super battleship today, it's a pack of iron plates, and it will definitely sink in the water!
Of course, it doesn't mean that they can't make a battleship covered with iron plates, but they basically can't make a super battleship as big as it is now, and the weight can't even be supported by the existing steel brackets in the dock. Dare to try.

Zhu Cijiong had a panoramic view of everyone's expressions. He knew that there would definitely be people who would ask questions, because this was not a whimsical idea, someone must have thought of it.

However, there is no ironclad battleship in Ming Dynasty yet, which proves that they must have problems that cannot be solved.

Sure enough, after a moment of silence in the meeting room, Sun Yuanhua cupped his hands and said, "Your Majesty, the humble minister you mentioned has also thought about it, but to resist the attack of shells, the thickness of the iron plate must be at least half an inch. Iron plates as large as the door panels weigh several hundred kilograms, so it is not a problem to make a small iron-clad battleship, but it is very difficult to make it as big as the current super battleship."

Zhu Cijiong shook his head in a rare way, and reminded: "No, no, no, Chuyang, more than half an inch is a bare iron plate. If there is a thick wooden board behind it, it doesn't need to be half an inch. Two minutes thick is enough. If the material is improved, To increase the toughness of the iron plate, one minute thick is enough."

This Sun Yuanhua has never tested it. Who would be so boring as to add a thick wooden board behind the iron board? When he tested it, he used all bare iron boards.

Fortunately, everyone is familiar with the emperor's temperament. If the emperor speaks in a pleasant manner, it means that he is not angry and is just discussing with you. He touched his head, indicating that he knew he was wrong.

Under Zhu Cijiong's deliberate guidance, the current academic atmosphere in Ming Dynasty has been relatively relaxed, and everyone is not as timid as before and dare not speak up. Just after Sun Yuanhua's denial, Bi Maokang clapped his hands again and said, "Your Majesty, I beg your pardon." Boldly, even if it is one point thick, it is more than twice as heavy as a wooden battleship. According to the size of a super battleship, it may not sink if it is covered with iron plates, but those gun ports are estimated to be submerged in water up."

Hearing this, Zhu Cijiong nodded, then picked up the brush that had been placed on the table, dipped it in ink, and began to draw on the big white paper in front of him.

His current painting skills are not boastful. With his deliberate practice, although he may not be able to reach the level of the famous painter Emperor Zhao Ji, he may not be far behind.

Under his pen, the profile of a super battleship slowly and quickly took shape, it was so lifelike, and everyone couldn't help showing admiration in their eyes.

Of course, he didn't come to show off his drawing skills, he stopped after drawing an outline, and didn't draw any more details.

He put down the brush, pointed to the super battleship on the picture and said, "The current ship shapes are almost like this, with a rounded bottom, like a long water scoop."

Everyone didn't understand what the emperor meant, it wasn't just Daming, it had been like this for thousands of years.

However, the emperor drew and talked, and there was always a little reaction, and everyone nodded in cooperation.

Zhu Cijiong picked up a brush and drew a waterline, and the boat seemed to be floating on the water.

Immediately afterwards, he pointed to the part below the water surface and said: "The reason why the boat can float on the water is because it displaces this part of the water. In fact, the weight of the boat is equal to the weight of the part of the water he displaces. This can be called The displacement of the ship."

At this time, there is no concept of displacement. Everyone frowned and pondered when they heard this. What does displacement mean?

Zhu Cijiong then explained: "Everyone knows what Cao Chong said about elephants. He is actually calculating the weight of an elephant by the displacement. When the elephant stands on it, the boat sinks a part, draw a line to mark it, and then lead the elephant to Go, and then use stones to slowly push the boat to the same position, so that the weight of the stone is equal to the weight of the elephant. Think about it, whether it is the weight of the stone or the weight of the elephant, is it because they row What is the weight of this cut of water?"

This is relatively intuitive, and everyone acted like a sudden realization. Obviously, they have understood the meaning of displacement.

Seeing that everyone had understood the concept of displacement, Zhu Cijiong picked up the brush and began to draw again.

This time, he drew a very strange boat, as if adding a long shuttle to the original arc-shaped bottom.

Seeing such a strange hull structure, everyone showed surprised expressions.

From an aesthetic point of view, this structure is ten times uglier than the old-fashioned structure. Why did the emperor draw such an ugly ship?

Zhu Cijiong still only drew an outline, but this time he drew the waterline together before stopping.

He put down the brush, pointed to the newly added shuttle-shaped cabin, and said, "If such a long shuttle-shaped airtight cabin is added to the bottom of the ship, will its displacement be increased? Is this the shuttle-shaped airtight cabin?" The larger the warehouse, the greater the displacement of the ship? Does the larger displacement mean that the ship can be made heavier? In this way, is there any problem with covering the ship with a layer of iron armor?"

Only then did everyone understand that the purpose of adding this shuttle-shaped structure was to increase displacement. In this way, no matter how heavy the warship is, it will be no problem, because the entire sealed shuttle-shaped cabin is sunk at the bottom of the water, and the water it displaces Not a little bit!
