Don't wait, the young man's head is white, empty and sad. Fastest updates

There are many people in this world, because of one reason or another, sad, sunk, self-abandonment, after a long time, still nothing, except for lamenting the injustice of fate, there is only empty sadness.

Zhu Cijiong did not indulge in sad emotions, after all, it was just the memory of the previous life, in this life, the Ming Dynasty did not die, and the Ming Dynasty is rising strongly, and it is necessary to work hard to win the hegemony of the sea in one fell swoop.

He will not sigh all day long, not want to forge ahead, slowly wait for the great powers to surpass, and then be sad.

Now, with ironclad warships, the Ming Navy is bound to be invincible in the world, of course, the premise is to make it first.

The next day, after the early dynasty, he summoned Bi Maokang, Sun Yuanhua, Wang Zheng, Song Yingxing, Xu Fuyuan, and Xia Yunyi, the technical backbones, to hold a pre-imperial meeting to discuss the production of ironclad warships.

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

Sure enough, as soon as Zhu Cijiong came in, after a salute from the monarch and the ministers, he said directly: "Everyone, I have summoned you here today mainly to discuss the problem of the ironclad battleship, that is, to coat the battleship with a layer of iron plates, so that not only is it difficult for the cannonball to injure the battleship, but the battleship itself can also be used as a weapon to ram the enemy's battleship, and in the face of the wooden battleship, the ironclad battleship will be an invincible existence!" “

When everyone heard this, some were dumbfounded, some were surprised, and some were thoughtful, with different expressions and different reactions.

Covering the outside of the battleship with an iron plate, this problem is not something that no one has thought about, but this is not a very simple thing, because the iron plate is quite heavy, and if the entire battleship is covered with a layer of iron plate, the weight will be terrifying.

Of course, it's not that they can't make a battleship covered with iron plates, but if they want to be so big as a super battleship now, they basically can't do it, and the weight can't even hold up the existing steel supports in the dock, who dares to try.

Zhu Cijiong took in everyone's expressions, and 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, the Ming Dynasty has not yet appeared ironclad battleships, which proves that they must have problems that cannot be solved.

Sure enough, the conference room was silent for a while, and Sun Yuanhua arched his hand and said: "Your Majesty, the micro-minister you said has also thought about it, but in order to resist the attack of cannonballs, the thickness of the iron plate must reach at least half an inch, in that case, an iron plate with a large door plate weighs hundreds of catties, and it is not a problem to be a small ironclad battleship, but it is difficult to make a super battleship as big as now." “

Zhu Cijiong shook his head rarely, and prompted: "No, no, no, Chuyang, more than half an inch is a light iron plate, if the back is padded with a thick wooden board, there is no need for half an inch, two points thick is enough, if the material is improved and the toughness of the iron plate is increased, one point thick is enough." “

This Sun Yuanhua really hasn't tested it, who would be bored to add a thick layer of wood behind the iron plate, he really used all the light iron plates when he tested.

Fortunately, everyone is familiar with the emperor's temperament, if the emperor speaks pleasantly, it means that he is not angry, just to discuss with you, otherwise a few words are enough to scare people into sweating, and now, Sun Yuanhua just touched his head in embarrassment, indicating that he knew he was wrong.

Under the deliberate guidance of Zhu Cijiong, the academic atmosphere of Daming is now relatively relaxed, and everyone is not as timid as before and dare not speak, Sun Yuanhua has just been denied, Bi Maokang arched his hand and said: "Your Majesty, please forgive Weichen for his courage, even if it is a point thick, it is more than twice as heavy as a wooden battleship, according to the size of the current super battleship, wrapped in an iron plate, it may not sink away, but those gun doors are estimated to be flooded." “

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

His current painting skills are not boastful, and under his deliberate practice, although he may not be able to reach the level of the famous painter Emperor Zhao Ji, I am afraid that it is not much worse.

In his pen, the profile of a super battleship slowly and quickly took shape, which was called a vivid and vivid, and everyone's eyes couldn't help but show admiration.

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

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

Everyone didn't understand what the emperor meant, not only the Ming Dynasty, but also for thousands of years.

However, the emperor painted and talked about it, and he always had to react a little, and everyone nodded in cooperation.

Zhu Cijiong picked up the brush again and drew a waterline, and the boat was as if it was floating on the water.

Immediately afterwards, he pointed to the lower part of the water and said: "The reason why the boat can float on the surface of the water is because it discharges this part of the water, in fact, the weight of the boat is equal to the weight of the part of the water that he discharges, and this can be called the displacement of the ship." “

At this time, there is no concept of displacement, and everyone frowned and pondered when they heard this, what does displacement mean?

Zhu Cijiong then explained: "Cao Chong said that everyone knows the elephant, he is actually using the displacement to calculate the weight of the elephant, the elephant stands up, the boat sinks a section, draws a line to make a mark, and then takes the elephant away, and then uses the stone to slowly press 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's the weight of the rocks or the weight of the elephants, is it the weight of the water that they drained? “

This is relatively intuitive, and everyone has made 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 again and drew it.

This time, he drew a very strange kind of boat, as if a long shuttle had been added to the original arc-shaped bottom.

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

If, from an aesthetic point of view, this structure is ten times more ugly than the old one, why would the emperor paint such an ugly ship?

Zhu Cijiong still only drew an outline, but this time he stopped painting with the waterline.

He put down the brush and pointed to the newly added shuttle at the bottom and said, "If you add such a long shuttle-shaped sealed cabin to the bottom of the ship, will its displacement increase?" Is it possible that the larger the sealed compartment of this shuttle type, the greater the displacement of this ship? If the displacement is larger, does it mean that the ship can be made heavier? In this case, is there still a problem with covering the outer bread of the ship with iron armor? “

Only then did everyone understand that the original purpose of adding this shuttle-shaped structure was to increase the displacement, so that no matter how heavy the battleship was, there would be no problem, because the sealed cabin of this shuttle-type was completely sunk under the water, and the water it discharged was not a little!
