Valley Emperor

The principle of the steam engine in the Datang Empire is actually not difficult. It can even be said to be very simple. It is nothing more than boiling water, generating high-pressure steam, and allowing the high-pressure steam to drive the machinery to work.

However, this principle may be very simple in the eyes of later generations, but for people in the sixteenth century, especially for semi-literate people like Alvin, it is not so easy to understand.

Not to mention that you can tell just by looking at a chimney.

What's more, even if you know the principle of the steam engine, it is extremely difficult to build the steam engine.

The steam engine, but a veritable industrial flower of the contemporary Tang Empire, is much more difficult than simply making guns and cannons.

If you want to build a practical steam engine, even if it can only be used to lift water in the early days, it is not so easy to build a simple and practical low-pressure steam engine in a factory.

The machining accuracy of the steam engine is very high. In order to ensure the continuous operation of the steam engine, especially the continuous reciprocating motion of the flywheel in the cylinder, the precision requirements are very high. If the machining accuracy is not high enough, it cannot be processed at all.

If the problem of processing can be solved by hand-polishing by skilled craftsmen one by one, then the raw materials of some core components are completely insoluble.

In order to ensure accuracy and strength, some of the core components in the steam engine are not ordinary pig iron wrought iron, or even ordinary steel, but special steel jointly developed by the Royal Institute of Technology of the Empire and several domestic iron and steel enterprises.

And it is also a different special steel. A certain part may require higher strength, and a certain part may require better toughness. Therefore, the carbon content of the steel used to manufacture these parts is different.

Therefore, on the surface, the entire steam generator seems to be of steel structure, but although many parts inside are made of steel, even if they are all steel, there is a huge difference.

Although the quality of all kinds of special steel produced by Datang in this year is incomparable with the steel of later generations, it is definitely not comparable to the inferior steel that the craftsmen in contemporary Europe have reluctantly trained by relying on various local methods.

If contemporary European craftsmen use the steel trained by the native method to copy the high-pressure steam engine of the Tang Dynasty as it is, then there will be such a situation. Under the premise of skilled craftsmen, it is a part of various parts that may be imitated. It's the same, and it can be assembled, but it's absolutely impossible to run. Even if it runs reluctantly, it won't last a few minutes before the cylinder will burst.

Datang's high-pressure steam engine has been developed for more than ten years, and most of these ten years have been searching for various special steel materials for manufacturing core components. In order to find these materials, Jiangnan Iron and Steel Co., Ltd. has tested various ratio formula I don't know how many, but this is what came out.

In contemporary Europe, if you want to imitate the steam engine of the Tang Dynasty, it must first have a complete industrial system, modern materials science, and then continue to extend to various modern disciplines such as physics and chemistry...

In the end, the Europeans had to establish a modern educational system first, and then a modern industrial system, and only then could it be possible to imitate the high-pressure steam engine that the Tang Dynasty used today.

Of course, if they just want to simply build a steam engine, it's not difficult.

There is a skilled craftsman who can knock two pieces of steel at random, and he can make a steam engine with a little effort, but such a steam engine can never be put into practical use.

When Alvin saw the steam battleship of the Datang Navy, he also wondered if he would find some people after returning to China to see if he could get this steam engine out.

But just think about it. The Portuguese have imitated steam engines for so many years, and they still have samples for imitation. Now they can't even come up with a low-pressure steam engine that can run normally.

The English people don't even have a sample, and they don't even know what a steam engine looks like. How about imitations!

When the Fujian battleship slowly left the port and raised its sails and sailed to the sea, Alvin took back his eyes after a long time. He looked envious of these giant ships, but envy was useless, so he should enter earlier. Hong Kong, and then buy the Datang merchant ship and ship it back to China to make a fortune is the kingly way.

However, Alvin did not know that there are no commodities in the South African port today, only empty warehouses, and the Fujian battleship he watched was actually going out to sea to meet and **** the merchant fleet from afar.

As for the South African port, I already learned from the fast communication ships between India and South Africa a few days ago that the latest batch of merchant ships departing from China, passing through India, and going to South Africa are on their way. According to the voyage, it is now a distance from South Africa There is still about half a month's voyage.

There are more than 50 ocean-going ships in this fleet. While the fleet is full of various materials, it also carries nearly 10,000 immigrants. When the fleet sails in the South China Sea and India, naturally there are no What trouble, these two sea areas are now the inland sea of ​​the Datang Navy, and some indigenous countries along the Indian Ocean, such as the Mughal Dynasty in India, the Safi Dynasty in Persia, the Ottoman Empire and some indigenous countries in Northeast Africa, Although these countries also have ships, the ocean power is not worth mentioning.

It is impossible to pose any threat to the huge ocean-going fleet of the Datang Empire.

Therefore, it is relatively safe in the South and Indian Oceans.

But when the fleet enters South African waters, it may run into trouble.

Even though the Imperial Navy has blocked the Cape of Good Hope, it is not a complete blockade. Recently, more ships from various countries have gathered in the waters of South Africa. These ships are merchant ships when they are doing business, and pirates when they are not doing business.

In order to avoid any accidents, the African Squadron of the Indian Ocean Fleet dispatched warships to respond and **** them.

When the Fujian battleship escorted the merchant fleet back, Alvin was able to buy the Datang merchant ship he wanted, whether it was silk, porcelain or perfume.

His beloved Alvin, driven by Alvin Grant, entered the reserved berth and anchored under the guidance of the South African harbour guidance ship, but when he was about to take people to transfer to the small boat, it was They were told they had not been allowed to disembark.

After asking carefully, they said that it was to prevent the disease, and they needed to wait on the boat for three days, and then they could go ashore after three days!

People have to bow their heads under the eaves, and Alvin keeps telling himself that he is a person who does big things and must be patient.

He came here because he wanted to buy goods and find a fat sheep on the way back, so he had to endure it now!

After three days of boring waiting on the boat, Alvin was allowed to go ashore with a vote of sailors. Of course, he did not bring all the sailors ashore. If all the sailors were brought ashore, it is estimated that the next day Alvin The document number does not belong to him.

Ask him why he is so worried!

Because the Alvin didn't belong to him before. He grabbed it from a pirate's den three years ago with a group of his men. At that time, the captain of the ship, the pirates, was careless and brought too many sailors off the ship. Going to be chic, but Alvin brought dozens of desperadoes to approach the boat quietly in the dark, then climbed onto the boat, directly killed the dozen or so pirates who were left behind on the boat, grabbed the boat and ran away!

Since then, the pirate ship has also been renamed the Alvin!

Although he estimated that such a thing was unlikely to happen in a South African port, it was always right to be careful when people were floating on the sea.

So he only brought half of his men ashore, leaving half of his men to stay on the ship, and promised to let the sailors take turns on duty.

After getting off the boat, he saw a large open space in front of the pier. There were dozens of people waiting in the open space. He didn't know where he was, but soon, there was a blond and blue-eyed man next to him, but he was wearing a Tang Dynasty man. The Portuguese in costume said with an authentic Portuguese: "Don't run around when you land, just wait in line in the square in front of you to register. If you run around, don't blame you for not reminding you!"

"Also, we have a lot of rules in the Tang Dynasty. After going ashore, we must abide by all kinds of rules. Remember not to defecate, spit, or litter anywhere, otherwise you will be severely punished!"

"And the most important thing is that we must not do illegal things in our Tang Dynasty territory. Theft, robbery, rape, and fraud are all unacceptable. Once found, they will all be hanged!"

After all, the blond and blue-eyed Datang port guide still pointed to a row of mummified corpses on the edge of the pier: "If you don't want to become one of them, just be honest!"

"Aren't they pirates?" According to tradition, those who were hanged and dried in the port were usually pirates. Alvin had seen at least dozens of dried corpses in this row before, and thought they were all caught pirates. Woolen cloth.

The guide shook his head directly: "There are a few pirates, but most of them are all kinds of robbery criminals, don't you see the signs hanging on them, it says, thieves, robbers, rapists, pirates It's all there!"

Steal something~www.wuxiaspot.com~ You have to be hanged for a robbery?

These Datang people are so savage!

And Alvin really can't understand the text above!

Although Alvin was able to converse with the port guide in Portuguese proficiently, he was completely illiterate and couldn't even recognize the alphabet.

As for why this illiterate, as an Englishman, is proficient in Portuguese, can speak and listen to a certain language, it has nothing to do with illiterate, after all, illiterate can speak!

What's more, although Alvin is an Englishman, as a great pirate, it is normal to be proficient in multiple languages, not to mention that Spanish and Portuguese are the common languages ​​of Western navigators these days. Foreign language, how to go out to be a pirate!
