Three Kingdoms

The lighting up of any technology tree cannot be accomplished by just talking.

There are a lot of things in Fei Qian's mind, but due to limitations of heaven, earth, and people, many things cannot be created or used at all, and there are not even substitutes.

Such as boats.

Of course there are things that are much more advanced than cars and ships, but can they be built?

Even simple combinations have problems, not to mention the use of materials that were not available in the Han Dynasty, and some mechanical combinations that cannot be made yet...

The development of ships in the Han Dynasty has actually entered a peak period, but unfortunately, like most "toys", it has not formed an effective systematic inheritance, resulting in some shipbuilding technologies not being passed from the Western Han Dynasty to the Eastern Han Dynasty Since then, no technical documents have been preserved, only some literary and mostly descriptive language.

There were already built-up ships in the Han Dynasty, and there were a large number of auxiliary ships, such as stern ships, to assist in battles, and there were even special positions for generals and captains, such as "lou-ship generals", "lou-ship captains", etc., which proves that In fact, during the Han Dynasty, especially during the Western Han Dynasty, the emphasis and use of ships was quite good.

But after the Eastern Han Dynasty, because Liu Xiu and most of the Eastern Han emperors after Liu Xiu adopted a contractionary policy, the Ling Canal originally built by the Qin Dynasty in South Vietnam was abandoned, not to mention the control of some waters and the training of boatmen. So much so that Fei Qian couldn't find any full-time boatmen in Chang'an.

Fortunately, the arrival of Ma Jun changed some Fei Qian's embarrassing situation regarding ship research.

After all, the Huang family is not very good at researching ships. There are many things that they only know a little about. When paired with Fei Qian, a guy who is even more half-baked, it is inevitable that the combination will be very shaky.

For shipbuilding, it does not mean to find a few pieces of wood, then saw, plan and nail them. Fei Qian originally thought that shipbuilding was not a big deal. After all, it was not like the mechanical iron-clad ships of later generations. Just improving the existing wooden ships should be a job that could be completed with just a few words. However, the reality is that for Fei Qian learned a good lesson.

The first trouble is not the problem of deconstruction, but the wood.

Who would have imagined that to build a wooden boat with about a hundred materials, more than 300 to 400 pieces of wood, or pieces, of different sizes were used, which were then repaired by shipbuilders and added and combined bit by bit. Finally it becomes a ship.

The so-called ship material is not the load-bearing unit, but the quantity of wood used in shipbuilding.

Ancient ships were built with wood, and a ship required many logs. For example, if it takes twenty logs to build a ship, the ancients would first calculate the quantity of materials. A twenty-material ship means that twenty pieces of wood are needed to build this ship. Later, as the habit of calling it gradually evolved, shipwrights used to measure the size of ships by the amount of wood used.

In the Qin and Han Dynasties, material refers to an ordinary piece of ship wood. Such wood is generally about five to six meters in length and about twenty to thirty centimeters in diameter. Due to the buoyancy of such a piece of wood in the water, it can basically bear the weight of two to three adults, which is about three hundred kilograms. Therefore, as the customs continued to evolve, the buoyancy capacity of the ship's wood in the water was gradually used to calculate the size of the ship.

However, with the passage of time and the inheritance of technical terms, by the Song Dynasty, one material became a unit of volume, and one material was equal to ten cubic feet (Song ruler)...

Therefore, the embarrassment of the inheritance of science and technology in China arises. Those who know how to do it do not know how to speak. Those who know how to speak may not know how to write, and those who know how to write do not know how to do it. Therefore, it is recorded in historical records. There are a lot of confusing quantifiers and descriptions, and it ends up being confusing.

If you are just building one or two small models, then the pool in the backyard of the Hussar General's Mansion is enough to replace it. But if you want to do a one-to-one physical study, then the space of the General's Mansion is too small. Therefore, Fei Qian surrounded a corner of Kunming Lake and used it specifically for Ma Jun to conduct research on ships.

As soon as we arrived at the shipbuilding workshop here in Kunming Lake, we were surrounded by all kinds of wood.

"The ship's masts should be made of straight fir, the ship's beams and rafters should be made of camphor, the shallow planks should be made of miscellaneous wood, the rudder should be made of elm, the crutches should also be made of elm, the sculls should be made of cypress, and the oars should be made of mountain oak..." Ma Jun led the way. As Fei Qian and Huang Yueying walked forward, they explained to the wood piled on both sides, "I heard that there is a strange wood in Zhuya. The material is fine, smooth and tight, heavy and resistant to stains. It will not crack when dried and will not rot when soaked. There is nothing you can do." ...』

"Oh...um..."

Fei Qian could only make some unintelligible sounds to echo, pretending to be an expert. After all, Fei Qian couldn't identify most of the wood that Ma Jun pointed to. He only knew that his eldest uncle and his second uncle were all his uncles, and the high tables and low benches were all made of wood...

So from a certain point of view, some business simulation games in later generations are already conscientious enough. Otherwise, they really have to be dealt with according to the actual situation. To build a ship, more than a dozen different kinds of wood are needed, and then they are stuck in a certain place. If you can't make anything out of a kind of wood, it would be strange if players who played Three Kingdoms didn't go crazy on the spot...

Further forward, there is a car and boat that has been made into an entity.

Cars and ships in history probably first appeared in the late Eastern Jin Dynasty. It is recorded in "Zi Zhi Tong Jian": "Wang Zhen'e led his navy from the river into the Wei River to go to Chang'an... Zhen'e went up the Wei River and took the Meng Chong small ship. All the sailors were inside the ship. The Qin people saw When the ship entered without a sailor, everyone was astonished and thought they were gods..."

Although this description does not directly mention vehicles and ships, "all the sailors were inside the ships, and the people of Qin saw the ships and there were no sailors", which shows that no one saw oars at that time, so they were very surprised when they saw the ships moving without oars. . From another perspective, during the Eastern Jin Dynasty, the technology to hide the treadwheels was already available.

But I don’t know whether it was due to technical secrecy or the war. It was not until the Tang Dynasty that cars and ships clearly entered the stage of history because of the needs of the Grand Canal.

When the car and boat were approaching, Fei Qian truly felt the size of the boat. How do I put it? Chinese people just like big and white, uh, black and long, well, that’s pretty much the meaning anyway. Ma Jun also inherited the fine traditions of China. Although it is said to be an experimental work, it is not meant to be a model at all, and it is also quite large.

Fei Qian had some rough impressions. When he saw the comparison between Zheng He's ships of the Ming Dynasty and Columbus's ships, it was as if Brother Yao and Brother Yangtze were standing together. This shows that the Chinese people have a deep understanding of "bigness". Pursue.

It's a pity that the damn Minister of War...

Fei Qian took a breath.

If we want to control the south of the Yangtze River in the future, the naval army will naturally be indispensable. Instead of thinking about setting up a naval army when it is urgent, it is better to prepare for a rainy day earlier.

To take a step back, even if you don't care about Sun Shiwan, if you want to have better control over Jiaozhi, you still need a naval force that can go from Sichuan and Sichuan to Jiaozhi, and once again open up the route where Ma Yuan entered Jiaozhi. Waterways bear the important task of transporting people, horses and materials.

In the Han Dynasty, all ships used oars. The larger the ship, the more oars were needed. But here’s the problem. Think about how long it will take for future generations of dragon boat racing athletes to train to reach a consistent paddle speed. You must know that with so many oars, if the speeds are different, let alone forward and backward, the oars themselves will become a ball.

Cars and boats make up for this problem, reducing the amount of training and allowing for higher speed and explosive power during short sprints. Of course, if you are talking about long-distance travel, then sailing is naturally the best option.

The carriages and ships built by Ma Jun also had sails, two sails, but now only the upright masts were standing, and the canvases were folded up and piled on top of the ship's planks. The turning wheels of the vehicle and ship are in the middle of both sides. It is obvious that they are even uncoordinatedly large. There are also three oar holes on the left and right sides of the vehicle. They are probably used to supplement power, or the wheels of the vehicle and ship cannot move. Sometimes used to assist navigation.

"Let's try it out..."

Both mules and horses need a walk, and the same applies to ships. Fei lurked on the shore and watched the ships start to operate under Ma Jun's orders. The huge wheeled carts started to rotate and surge under the trampling of human power. A large amount of water splashed up, leaving the shore and heading towards the interior of Kunming Lake.

The rolling wheel car hit the water surface, stirring up huge waves, and then provided the driving force to move forward. The car and boat moved very fast on Kunming Lake. In less than half an hour, they had already covered nearly half of the circle. Then he circled back again, stopped at the shore, and dropped the anchor.

Everything seems right, but everything doesn't seem quite right.

After the ship stopped at the shore, Fei Qian boarded the ship.

Sure enough, as Huang Yueying said, a large amount of water was brought out due to the function of the flap. Not only were there obvious traces of water splashing on the deck, but also when the upper deck was lifted, one could also see the water in the cabin. There is also some silted water in it. Several boatmen are cleaning up the cabin.

"Well..." Fei Qian frowned a little. After all, it has only been driving for about half an hour. If there is so much water in such a short time, it is indeed not suitable for use. Even if people are sent to clean up the water in the cabin, long-term soaking will cause the bottom of the boat to stick. The joint parts are easily damaged and corroded.

Is there anything that has not been done well?

The technology of rollover is very mature. After all, in many places, even the second generation and improved version of rollover are used to irrigate farmland. Therefore, basically transplanting it to ships should not be technically difficult. yes……

etc.

Fei Qian suddenly felt that he had caught some problem, but he couldn't remember what it was for a while. He touched the back of his neck in depression, frowned, and looked left and right.

Penetration-proof watertight cabin?

There are some too, although there aren't many, there are only five vertical ones. Could it be that there should be a few more? It doesn't seem right either.

Fei Qian mentioned the watertight cabin to Huang Yueying at the beginning. After all, this thing is a big weapon of the ship, almost like a cavalry horse shoe. This thing actually existed in the Han Dynasty, but it was not popular. It was only in the Wei and Jin Dynasties that it became a standard feature of ships.

Oh, remembering what the problem was, Fei Qian couldn't help but laugh...

"I see! The car rolled over, haha, this is a complete car rollover..." Fei Qian patted the large wheel plate next to the car and boat and said with a smile, "That's the problem! 』

Huang Yueying was stunned for a moment, and then seemed to have some thoughts.

Ma Jun frowned a little, obviously not quite understanding yet.

Fei Qian laughed and said, "What is the use of an overturned thing?" 』

Ma Jun gradually opened his mouth, then stamped his feet and sighed, "Oh! Someone didn’t expect this! 』

In fact, there are some things that, before they were revealed, it seemed that they had no idea what went wrong. If you look at the ship alone, there is no problem. If you look at the overturned car, it will be no problem. If you add the two together, the result will be a problem. When looking for problems with the boat, nothing seemed to be wrong. When checking the overturned car, it was the same as before, and there was nothing wrong.

But here's the problem. The original purpose of the rollover is to lift water from a low place to a high place for easy irrigation...

That's why there is such a big splash when the car and boat are moving!

Cars and ships need power to move forward, and they do not need water to irrigate the ship itself. However, if the wheels are made strictly according to the overturning standards, will there be no problems with the amount of water? It was not at all what Huang Yueying thought the holes and gaps in the ship were at first. If your thinking is wrong, you will naturally not be able to get out. So the solution to this problem is actually very simple, just remove the original water-lifting function of the rollover.

Of course, from the perspective of God, you will feel that this one is also a fool, and that one is also a fool, why can't you think of such the simplest and most basic things, but in fact, in the history of China, most of the inventions and creations are just these " After the "idiot" and "idiot" suffered a bloody blow to their heads, they still persisted in studying, and only then did China's splendid civilization come into being.

Ma Jun was anxious to make the changes himself, but was stopped by Fei Qian, "Just leave this matter to the craftsmen... Come here, let's take a look at other things..."

Fei Qian didn't have time to stare at the Kunming Lake shipbuilding workshop every day. Since he came here, he naturally used it as much as possible to see if there was anything that could be improved.

Come on, if you don’t want to find Du Niang who is increasingly rich and have no bottom line, how many people can really understand the difference between the ships of the Han Dynasty and the wooden ships of later generations? In other words, what parts or structures are worse than the Song Dynasty and the Ming Dynasty?

There are keels, watertight cabins, planks, parapets, oars, oars, rudders, sails, anchors...

It seems that the ships of later generations also exist if they exist now, and it seems that the ships of later generations also exist now.

Fei Qian walked slowly around the ship, and then stood in front of the sail mast.

The sail mast is straight and high.

The sails under it are piled up in layers and piled under the mast.

Fei Qian pointed to the sail and said, "Pull it up and take a look..." There was no wind in Kunming Lake at the moment, so there was no big problem in just pulling it up.

It is a very traditional rectangular sail, fixed by five or six crossbars and ropes in the middle of the sail. Although Fei Qian standing on the boat did not feel any wind, there was still some breeze flowing in the air after it was pulled up, supporting the sail. Gotta be a little bulging.

"Okay, let's put it down..." Fei Qian noticed that the upper and lower crossbars of the sail cannot be moved, which means that the sail can actually achieve its greatest effect when the wind is downwind. Usually, paddles are used. There are mostly oars, so the Battle of Chibi happened. Did Kong Ming have to borrow the east wind?

The use of wind power to propel ships can be said to be the most practical, effective and far-reaching invention of human navigation technology. The development of Chinese sailing has similarities and differences with other civilizations in the world.

As we all know, the best wind is from the stern of a ship, because it is a tailwind. Downwind is the best direction for a ship to absorb wind. This is the most commonly used Chinese wishing expression "bon voyage" and "smooth sailing".

However, wind in nature comes from all directions. When the wind is against the wind, the wind becomes a resistance to the ship's progress. Therefore, the ships of the Han Dynasty could only furl the sails and use manpower instead.

If you want to make full use of the wind coming from the side, the direction of the sail must be adjustable, that is, it must be at a certain angle with the incoming wind, and then it can generate a force perpendicular to the wind direction, which can be broken down into moving the ship forward. thrust, so the sail is required to be movable and can be adjusted according to different wind directions...

So when Fei Qian told Ma Jun about this idea, Ma Jun suddenly felt like he had found a treasure. He immediately called a few craftsmen to start improving the sail, and then followed Fei Qian closely to see if he could get it from Fei Qian. I'll get some other pointers over there.

But it is a pity that Fei Qian himself is only half a bucket of water. All his impressions about wooden boats come from the Internet and movies of later generations. He actually knows nothing about the actual practice, so after two more rounds, there is no follow-up inspiration. , so we can only give up here and wait until Ma Jun produces the improved version 2.0 of the vehicle and ship before taking a look.

When Fei Qian and his party returned to the Hussar General's Mansion, as soon as they got off their horses, Fei Qian saw the waving flag at the front gate of the Hussar Mansion. Suddenly his heart skipped a beat, and he remembered something again, and frowned.

I seem to have read somewhere that the suitability of a jib is higher than that of a jib?

"Husband..." Huang Yueying walked to Fei Qian and asked, "What's wrong?" 』

"Look at those flags..." Fei Qian pointed to the big flags in front of the government office, "Does it look like a sail?" At this time, the wind strength should be the same, and the two flags are about the same length. But why does the four-cornered flag move slowly and the pennant moves quickly? What would happen if the ship also used triangular sails? 』

Huang Yueying also raised her head and stared at the flag that was fluttering in the wind, "A triangular sail..."
