Sweep the World

The Han Empire actually had a mechanical drive device, but to put it bluntly, it still relied on manpower to drive it, not a mechanical drive device in the true sense.

The Navy currently has 15 gunboats, among which the "Quanzhou" is equipped with a gear-mode drive device, but it is manpower (animal power) that makes the gears generate power, and only a small part of the gear structure uses metal.

The so-called gear drive mode can be regarded as an alternative super-complex version of "donkey grinding", which is composed of many large and small gears and bearing shafts to form a force-increasing method of large and small gears.

The test of the drive device of the "Quanzhou" was not successful. Firstly, the materials of the parts could not support the wear, and secondly, even if the gear arrangement had problems, the service life was too short and the failure rate was too high, etc. And so on.

The layout is the relationship of the components, in fact, there is still an error in the layout position.

Steam engines have been studied and installed on ships in history. It is not unreasonable to use the layout of the rowing device on the left and right sides of the ship. The main reason is the lack of horsepower. The layout can be used as much as the horsepower is limited. Greater role.

The first-generation marine thrust device was the kind of blades that looked like a circular waterwheel. It was not a blade like a propeller. Maybe it was not because of insufficient imagination. It was the premise of insufficient power. The area of ​​the blades of the circular waterwheel was large after rent. , And then the incremental rolling mode can exert more performance.

"Your Majesty, the thrust device is arranged at the stern, and the position of the rudder is also changed..."

The Horse Club speaks a lot of professional terms, including some parts of the ship and related parts.

Some Liu Yan could understand, and many others could not understand.

The rudder is a component that controls the direction of the ship. It does not need to be arranged in any position. It is not the same size as the rudder of each ship. It is still necessary to consider the tonnage of the ship itself, and then consider how to arrange it. The size of the rudder is designed according to the tonnage of the vessel.

"The rudder of the'Quanzhou' has undergone 17 changes, and finally the location and size of the layout can be determined to enable the vessel to turn to the greatest flexibility." The'Quanzhou' referred to by Ma Hui is currently the owner of the Jiangnan Shipyard. Base: "The rudder is being redesigned, and the hull is also being redesigned."

Liu Yan remembered it. There seemed to be a memorial that mentioned that the "Quanzhou number" had only been used for less than two years, and that there was a problem with the keel that could have been used for ten years. But under the premise of continuous maintenance of the keel, there was still a big trouble that must stop sailing.

Facts have proved that as long as it is related to science and technology, there is no one thing that can happen overnight. All of them are constantly experimenting and constantly improving in the discovery of problems. The perfection may reach 99%, but it is discovered. The irreversible problem eventually overthrew the overall design.

If you do not get involved in a certain field to a certain extent, you will not find that the field is far more complicated than you know. It can even be said that the more you study this field, you will find that the confusion will not become less and less, but on the contrary. With the deepening of the research, more confusion arises.

Those who do not know how to look at a ship are looking at a long-shaped object.

Those who know how to look at the ship will wonder whether that design is right and whether the design of the water level and below has reached the best.

When a ship is sailing in the water, we must consider what kind of line it should be in order to minimize the resistance of the water itself. After repeated experiments, it was first discovered that the original sharp triangle lines, or the perfect arch, would be the best design solution.

Further research will reveal that the shape of a razor below the water level will not only minimize the resistance, but also provide the maximum stability of the ship.

Liu Yan had already boarded the iron ship and saw that the deck was full of metal, and the answer was only a layer of iron sheet.

The iron ship is divided into three floors, with only one deck on the deck and two floors on the cabin.

The flagship room is placed in the middle and rear position, which happens to be between the stern mast and the midship mast.

"The mast is made of wood..." When Sang Yu looked far away, the mast was also pitch black. He took a closer look and knocked again, and found that it was not iron: "That's right. The sails are fire cloth, since the sails It doesn't burn, it doesn't matter whether the mast is made of iron or not."

That's right, what Sang Yu was talking about was Huohuanbu.

According to legend, Liu Che, Emperor Wu of the Han Dynasty, obtained a piece of fire cloth from the Western Regions, and found that no matter how it was burned, it would not be destroyed, and it was regarded as a priceless treasure.

The so-called fire cloth is a kind of asbestos cloth. For a long time, it has been regarded as a priceless treasure. people.

There are asbestos mines on the land of Zhuxia, with more asbestos mines in the Hexi area, and only two sites have been explored in the south.

It was not the people from Zhuxia who first discovered the characteristics of asbestos minerals, but from Asan's side, and then it spread to the Western Regions.

If you look through the history books, you will find that the people who sell the treasures in the land of the summer with the fire cloth are not the people of the Western Regions or the so-called Tianzhu people.

The Han Empire swept the Western Regions, and there was a family who wanted to exchange the secret of asbestos for the price of survival. Of course, the secret was learned by the Han people, and that family did not get the chance to survive.

The navy has long wanted to obtain a sail that is not afraid of fire. The four Han people who learned of the secret of the fire cloth accepted the navy's reward. They got what they deserved. The navy has mastered the secret of the fire cloth, which is equivalent to the center. Mastered the secret.

When something is no longer a secret, then there is nothing surprising, especially when national power is used to produce it, the less the thing will be that the minerals it finds are not enough, it is definitely not due to the lack of productivity.

It was originally a treasure of fire, but only because the navy has mastered the production technology, the treasure has become an ordinary thing.

"It's just an iron shell?" Liu Yan put on a round of inspection. There is a metal structure inside the hull, but the main material is still wood: "Since it is a wood structure, what are the considerations for using a metal waterproof hatch?"

Ma Hui showed an awkward expression, and replied: "If you have relevant concepts, accumulate some experience."

Yes, this is an experimental ship. The prerequisite to guarantee that it will sink without going into the water must be to maximize its use value, regardless of whether it is a reliable thing, you can install it and build it. establish.

Liu Yan got off the lower deck and did not check the sailor's lounge, but came to the stern position.

This is emptied. Looking at some architectures, you can find that it seems to be vacant. If you look at the styles of the architectures, you will find that it is not a random display, as if you are waiting for something to be installed.

"The minister thought that the iron armored ship was not driven by wind." Ma Hui didn't know why, and a fanatical expression appeared on his face: "The'Quanzhou' can run as fast as 16 knots with mechanical drive. Although it can only last for five minutes. However, Chen believes that ships should use mechanical energy instead of relying solely on natural wind power."

What Ma Hui didn’t say was that the Quanzhou Ship ran 16 knots, but the price was that the gear mechanism turned and collapsed. At that time, 24 people were supervised and maintained, 13 of them forever. I closed my eyes.

"The'Quanzhou' is nearly 1,000 tons and can run 16 knots. The minister has made a guess..." Ma Hui said excitedly: "If the device can be guaranteed to run and drive ships under 100 tons, will it be able to run? Thirty-five quarters?"

Liu Yan couldn't hold back, he laughed dumbfounded and looked at the horse club whose expression of excitement turned into a constipation, and reminded: "Volume."

If the device installed on a thousand-ton vessel is to be installed on a one-hundred-ton vessel, the size of the machinery must be reduced, and it is necessary to consider whether it can achieve the same efficiency once it is reduced.

"..." Ma Hui, of course, has considered shrinking. If someone else opens his mouth and squirts, he can only hold back in front of the emperor and compliment against his will: "Your Majesty Shengming."

People engaged in scientific research, they may be a bronze in other fields, but they will be a king in the field they know well.

They are not afraid of repeating failures on a scientific research project, because all failures are accumulating experience for success.

Those who are engaged in scientific research, they are most afraid of bureaucracy. Those bureaucrats who don’t even know a fart, prefer to talk about their official position, and give guidance in the name, so that the scientific researchers are doomed to fail to succeed. If you do it, you will lose the chance to continue to fail.

Liu Yan mentioned the "idea", at least he was right.

After Ma Hui was depressed, he became more excited.

Many of the technological products of the Han Empire were raised by the emperor. Those who did not engage in scientific research would take it for granted that the emperor knew everything, but those who engaged in scientific research knew that the emperor must have the quality and knowledge for scientific research.

"The navy made that animal power device..." Liu Yan touched the metal bracket and said with a smile: "I know it's a transitional product at best, or let them do it."

The horse will stop breathing, looking at Liu Yan's mouth eagerly, his heart beating violently.

"You should try everything, otherwise, how can you know if there is any result?" Liu Yan didn't pay attention to the horse club, and walked a few steps to look at an occlusal device on the ground: "Animal power is naturally not good, and it is doomed to fail. , Just to make the gear application get enough accumulation, it is the success of the gear application."

The horse will continue to hold his breath, the sixth sense that will be rewarding becomes more and more intense.

"It's up today, you can go to Chang'an." Liu Yan squatted down and looked at the occlusal device, guessing what it was used to fix, while saying: "The Shaofu is working on the'big teapot' project. You may be able to join in."

The Mahui knew that this was what he had gained. When he regained his breath, he inhaled and exhaled. He didn't know if he was holding it or what, his face was flushed.

The so-called "big teapot" project is of course the study of steam engines. Related work has been in progress since Yuanshuo ten years ago. Four years later, we have figured out how steam is produced. From the beginning, we simply experimented with boiling water to observe steam. The thrust of steam is also tested, and various pipes perform steam functions.

Liu Yan went on a trip before leaving Chang'an and found that the relevant personnel had entered the stage of observing steam entering the cylinder. He also heard that there have been several explosions before. Fortunately, there were only injuries and no one died as a result of the accident.

Once the steam engine research has entered the cylinder stage, all that remains is to figure out what layout method should be used for the internal structure of the cylinder.

Liu Yan is not familiar with steam engines, but he knows that cylinders need to have two things like sliding valves and pistons. No matter how many things he has, he has no relevant knowledge.

The "big teapot" project shocked the researchers just because Liu Yan mentioned the sliding valve and the piston. They had been wondering what was missing before, but it took time to think about it from scratch, and it also required repeated failures. , After countless failures, the components and structures are constantly changed, and finally the results are produced.

Liu Yan didn't understand the layout of the sliding valve and piston of the cylinder, or else he should conduct the experiment himself. Although he is eager in his heart, he can only wait patiently. Maybe this year's "big teapot" plan will produce results, and it may take another three to five years or even longer.

If the "big teapot" project succeeds, it will not be the navy that will benefit first, but will definitely be used on land first.

Just knowing how steam generates power does not mean mastering the use of power. The next step is to support mechanical technology. Otherwise, if there is a steam engine without the supporting linkage and flywheel device, the power generated will only be evaporated. Effect.

"Quanzhou" went to engage in gear machinery, isn't it just exploring the power output of the steam engine?

The kinetic energy of the steam engine drives the flywheel to run. The next step is the bearing and gears. When they turn, they are an application of power. As long as they can turn, the next step is to consider increasing the horsepower.

Liu Yan looked around and found that the layout of this place was waiting for the installation of related machinery. He was wondering why the “Quanzhou” had proved inappropriate to be installed at the stern, so why did he choose the stern layout.

"A set of abrasive tools have been built in Kuaiji~www.wuxiamtl.com~ and a batch of gears have been cast." Ma Hui was not sure whether Liu Yan knew what was going on, and naturally did not dare to hide it when asked: "The minister knows that it is. Steel is used."

Liu Yan nodded, without other expressions.

An exploratory spirit is great, especially when it comes to technology. Isn’t it the premise of trying everything to produce results?

Perhaps because of the need to experiment with something, new scientific research results have been produced instead of what was needed. This is what the science and technology tree is all about.

In the country Liu Yan founded, in the twelfth year of Yuanshuo, the annual pig iron output had reached the output of Russia in the mid-nineteenth century.

Perhaps it should be said that the total output of pig iron in various countries in the world today is probably a fraction of the Han Empire.

The Han Empire now produces 260,000 tons of pig iron and 430,000 tons of steel annually.

I don’t see much, but what I need to know is that it’s only 356 AD, not 19XX!
