Steam Daming: Stop calling me to supervise the country

Chapter 8 The Steam Engine

The four craftsmen saluted Zhu Zhanchang, and Zheng He asked him to sit down first and introduce him one by one.

The fattest of the four had dark skin, a bald head, and a scar on his face, from the base of his ears to his cheeks.

He called Fang Qiang the chief engineer of Zheng He's fleet. He was mainly responsible for the construction of ocean-going ships. Although he looked scary, he had the honesty and integrity of my Chinese farmer, and he was a reliable craftsman.

The shortest one is estimated to be no more than 1.6 meters tall. Although he is not tall, he is full of tendons. His name is Zhang San. Zhang San, the outlaw fanatic, is the weapon maker of Zheng He's fleet.

The other two tall men are two brothers, Li Si and Li Yu. Their father was a captain and part-time best blacksmith in Zheng He's fleet. He passed away a few years ago. OK

Zheng He was an expert at first glance, and the four craftsmen he invited, a carpenter, a blacksmith, and a weapon master, each had their own strengths.

Zhang San couldn't wait to ask: "His Royal Highness, we have studied the device brought back by Lord Zheng, and I think the most exquisite is the connecting rod. Such a simple device can transform the simple up and down motion into the rotation of the wheel, which is exquisite. "

"It's the most amazing thing that the Fifth Highness can come up with this simple discovery from the simple discovery of opening the lid of the pot with boiling water."

The four of you started talking in a word, Zheng He stood up and signaled them to stop first, then waved and ordered the next person to bring out an enlarged version of the "steam engine".

It is the enlarged version made by Zhu Zhanchang before. Zhu Zhanchang looked around and saw that the connecting rod and the wooden wheel are very well made. These should be made by the carpenter Fang Qiang, but the technical content of these things is not very high. , the connecting rod can be slightly improved.

As for the kettle, they made an enlarged version of the kettle, and even the spout was scaled up as it was. Zhu Zhanchang gave a wry smile, not sure whether to praise them for their meticulousness or to say they were mindless.

The four of them looked at Zhu Zhanchang with expectation as if they were waiting for the teacher to pronounce the test results.

Zhu Zhanchang looked at the device in front of him, and was quite satisfied with the craftsmanship of several people, especially the kettle. It is naturally good for such a large kettle to be smelted.

In fact, Zhu Zhanchang underestimated the craftsmen of this era. After all, there was a magic camp in the Ming Dynasty, and guns and artillery could be made. Although the manufacturing process was backward, the level of craftsmen was not low.

"Master Zheng, the kettle is just a phenomenon I observed at the time. You don't need to rely on the kettle to make a steam engine."

"Don't need a kettle?"

"Yes, you should have experimented before, can you tell me what is driving the wheel to move."

Fang Qiang said: "The water in the pot is boiled and the lid is opened, and the movement of the lid drives the wheels."

Zhang San shook his head. As a weapons expert, he obviously observed more: "It's the heat, it's the heat that drives the lid."

"Yes." Zhu Zhanchang confirmed his thoughts and then said: "Yes, it is hot air, or we call it steam with a more accurate name."

Zhu Zhanchang started a small physics class and explained to them that the lid of the pot was opened because the steam was pressurized in the pot.

"So you don't have to stick to the shape of the kettle. We don't need a kettle. We just need the steam generated by boiling water. The kettle itself exists only for the generation of steam."

Zhang Sanyi patted his head: "It's me who is stupid, thank you Your Highness for clarifying the confusion."

At this moment, the four craftsmen in front of them could no longer have any thoughts of despising the boy in front of them.

"The steam is introduced into a closed space, and there is a lid-like device connected to the connecting rod, which can be called a piston, a movable plug."

"Pistons, this name is very good." Zhang San praised.

Zhu Zhanchang continued: "It must be airtight." Then he drew a simple flow chart and schematic diagram on the paper.

Zheng He and several craftsmen looked at it very carefully. Zhang San was amazed again and again. He wondered how this child could hide so many wonderful ideas in his head.

"His Royal Highness, this doesn't seem right. If you keep rushing steam into it, will it explode?" Zhang San discovered the problem. Although he hadn't learned about air pressure, he knew it.

Zhu Zhanchang also drew a pressure relief hole in the closed space, and the switch of the pressure relief hole was connected to the connecting rod.

"The switch here opens when the piston is pushed to the top, the steam is expelled, the piston falls, and after it falls, it closes and the steam continues to pressurize."

Zhang San's eyes widened with excitement on his face: "Miao ah, wonderful ah, where is His Highness's connection?"

"It takes many attempts to find out, but since it is a regular exercise, there must be a most suitable place."

"That's right." Zheng He couldn't help applauding.

If the previous few people were still amazed by Zhu Zhanchang's idea, now they really feel that it is possible.

I thought that even if I had this idea, it would take a long time to develop to realize it, but now it seems that it is close at hand, and a simple picture is clear and clear.

"Master Zheng, a few of us will do it now." Several people were already eager to try.

Zheng He said with a smile: "Wait first, don't be in a hurry, let's think about what we can think in detail before we put it on paper."

Several people began to discuss again and again, Zhu Zhanyi listened on the side, and mentioned that the inner wall should be smooth enough to seal.

You can't say everything at once, or people won't feel weird?

Slowly, step by step, he does not hope to make a steam engine in one performance, there is a process of research and experimentation.

Until dinner was about to be eaten, a few people could be considered to let Zhu Zhanchang go. Zhu Zhanchang could be regarded as aware of these people's curiosity and spirit of exploration, and it was simply tireless.

When he was leaving, Zheng He said respectfully, "Five young masters, starting tomorrow, I will order someone to build it and present it to you as soon as possible." His respect came from the bottom of his heart, not just because of Zhu Zhanchang's identity.

"Master Zheng, if something can be done, show it to Grandpa Huang and Father first."

"Understood, the son is thoughtful."

Chu'er, who was with him all the way in the carriage today, was extremely puzzled: "Young Master, why are you making this iron lump called a steam engine?"

Zhu Zhanchang smiled, opened the curtain of the car and said, "For the Ming Dynasty outside where the country is rich and the people are strong and live and work in peace and contentment."

Chu Er was even more puzzled.

"Chu'er, have you ever seen a war?"

"I have only seen rebellious refugees." She was born in the first year of Yongle, and had heard of the war in the frontier but had never seen it.

"You have seen starvation everywhere, tens of thousands of people were slaughtered in a city, the enemy army took pleasure in killing me, the old, the weak, women and children, and even competed to see who killed more, heads rolled all over the ground, babies could not escape bayonets, and the country signed a treaty that forfeited power and humiliated the country , ceding the land to pay compensation, and the people on their own land are reduced to third-class people and bullied by others, can you imagine such a world?"

In the Ming Dynasty, where the country was rich and the people were strong, even a maid in the palace could not imagine such a life as a low-level person, but such days actually existed in history for nearly a hundred years.
