Daming Military Empire

Chapter 292 Propulsion System
Zhu Cijiong, who is next to the draftee, can finally deal with business. As for the preparations for the wedding, his teacher Xu Guangqi and the two empress dowagers will take care of it. Things have to be dealt with first.

The most urgent issue is the issue of captives. This time the battle on the three major grasslands has captured more than 30 people from the Manchu and Mongolian armies. Zhu Cijiong has already ordered the three armies to pull all the captives out of the capital, of course not to pull them over. Cut it off, he wanted to use these captives to build a new city in the east of the capital.

According to the plan years ago, the Dongcheng District was mainly to open shops and build workshops for the merchants who gathered in the capital. Once the price is good, it will be almost the same. As for the house, the merchant who bought the land will naturally build it himself.

This time, it was the Qin army and the cavalry of the Guanning army and Tianxiong army who guarded the prisoners to build the city wall. The Qin army and Tianxiong army had no experience in building city walls, but the Guanning army was different. They were the authentic Liaodong army. , Building the city wall is much better than the Dingliao army. Under the auspices of Cao Wenzhao, the city wall is soaring upwards. It took only about ten days, and the main part of the city wall was completed!
Zhu Cijiong saw that they built the city wall so well, so he ordered them to build a state guesthouse-style villa area outside Dongzhimen, which is close to the Imperial College, that is, the Academy of Arts and Sciences of the Ming Dynasty, for the residence of envoys from various countries and those who came to Daming to take the exam. The plan of this state guesthouse is About 3 mu, all of which have been built into simple and elegant two-story buildings, with pavilions and pavilions in the middle, and gardens and rockeries. It can accommodate [-] to [-] people at the same time. The place.

After the affairs in Dongcheng District were almost handled, Zhu Cijiong finally had time to organize the development of the steamship. Of course, this development was different from the development of later generations. His so-called development was actually to draw a sketch and let Bi Maokang and the others do it!
It was still his private study, and he still had a few cronies. The development of the steamship this time only involved the Ministry of Industry, so Zhu Cijiong only called Bi Maokang, Wang Zheng, and Song Yingxing. Knowing how harmonious they are, after sitting down, Bi Maokang dared to tease: "Your Majesty, we are going to get married soon, I am afraid you will not have time to teach us old courtiers anymore, tsk tsk, three thousand beauties, some busy!"

Zhu Cijiong rolled his eyes, and said angrily: "It's 120, okay? The rest are court ladies, but some Korean and Dongying girls are really not bad. I didn't choose any of them, and I'll keep them for you. How about Give you one or two hundred, and let you be busy?"

Bi Maokang hurriedly cupped his hands and said: "Your Majesty, you should spare this humble minister, even at this age, I can't stand their tossing."

Only then did Zhu Cijiong proudly say: "Well then, I will keep it for you first, and when you want it, you can just say it."

Hey, let you be cheap with me, I can't play with you to death.

How could Bi Maokang dare to talk about the three thousand beauties, he quickly changed the topic and said, "I don't know why the emperor recruited us this time?"

What to do, of course, is to build a ship, but Zhu Cijiong did not give an answer immediately, but habitually guided: "Menghou, do you think sailboats or trains are faster?"

Bi Maokang thought for a while, and replied in a reasonable manner: "Well, it depends on the direction of the wind and the direction of the water. If the wind is smooth, the sailboat may be faster than the train. At other times, the train is faster than the sailboat."

Zhu Cijiong continued to guide: "Then what if there is no wind and no smooth water?"

When Bi Maokang heard the words, he couldn't help wondering: "Your Majesty, the sailboat can't move without wind or smooth water, how can it compare with the speed of the train?"

Zhu Cijiong just wanted them to consider how the boat would move without wind and with the water. He continued to guide: "Isn't it still possible to paddle?"

Bi Maokang was even more strange. He said in disbelief: "Your Majesty, sailboats are usually big boats. If you paddle, how big are the oars, and most people can't paddle such big oars!"

Zhu Cijiong directly asked: "If people can't move, then nothing can move?"

Hearing this, Bi Maokang frowned and pondered, and soon he said excitedly: "Does the emperor mean to use steam pistons to drive the oars?"

Zhu Cijiong slapped his hands and encouraged him: "Smart, that's what I mean, but it's not enough. Chang Geng and Liangfu, think about it too, how to make the boat run as fast as the train when there is no wind or smooth flow."

The ship is actually not complicated, especially the paddle-wheel type, you only need to take a look at it to understand, the key is this, they have never seen it before!
The three of them frowned and pondered for a long time, but they couldn't think of any good solution. Zhu Cijiong couldn't help but continued to remind: "What if we combine many oars to form a circle?"

Song Yingxing immediately replied excitedly: "The emperor means to make it like a waterwheel?"

Zhu Cijiong nodded in approval and said, "Yes, that's the way it is, but it can be made wider, as wide as the hull of a ship, with greater propulsion power!"

When Bi Maokang and others heard the words, their eyes lit up with fiery light. Zhu Cijiong could tell when he saw them like that. Without him drawing sketches, these people all understood what the paddle wheel propulsion system was all about.

However, there are not only paddle wheel type ships, but also propeller type. Zhu Cijiong thought for a while, then suddenly picked up a piece of paper and gently stirred it up.

Seeing the emperor like this, the three of them were all stunned. It's winter. Although the study room has the latest heating system, it's not hot enough to blow the wind. Could it be that the emperor suddenly went crazy!

Seeing their surprise, Zhu Cijiong didn't care at all, but pretended to be mysterious and said: "I don't know why I want to stir up trouble, right?"

The three of them nodded foolishly, really not understanding what the emperor wanted to do.

Zhu Cijiong stretched out his hand holding the paper to the middle of the table, fanned it a few times, and asked, "Did you see it clearly?"

The three of them nodded again foolishly. Such a simple movement was being done in front of their eyes, how could they not see clearly, the emperor must be really sick!
Of course Zhu Cijiong was not sick, he gently fanned the white paper while explaining: "Have you noticed that this paper will deform when you fan the wind?"

The three of them naturally saw it, and they nodded in unison.

Zhu Cijiong suddenly asked: "Do you know why paper deforms?"

Now the three of them stopped nodding and started shaking their heads.

At this time, Zhu Cijiong stopped the fanning movement, and directly used the other hand to gently hold the white paper in an arc shape with the palm, and then asked: "Is it the same as when it was deformed just now?"

The three of them took a closer look, and found that the arc was indeed similar to when they first fanned the flames, so they nodded again.

Only then did Zhu Cijiong explain: "This proves that when the paper fanned the wind, it was resisted, and it was the resistance that deformed it."

Now tell them about aerodynamics, they naturally don't understand, so the three of them looked at a loss.

Zhu Cijiong pointed to the slowly turning fan behind the fireplace and said, "When you made the fan, did the fan fall backwards because the base was too light?"

They did come across this when they were fanning the fan, and it was Zhu Cijiong who taught them to make the base heavier so that the fan could stand firmly on the ground.

Zhu Cijiong continued to guide: "This proves that the fan also encounters resistance when fanning the wind, and the resistance is still very high. Think about it, if the blade of the fan is made bigger and installed at the bottom of the ship, will it be able to push the wind? Go forward by boat?"

When the three of them heard the words, they all suddenly realized that this is actually the propeller propulsion system. Zhu Cijiong just used a more intuitive way to slowly guide it out. If he directly said something about the propeller propulsion system, the three of them would definitely not understand it.
