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 a boat.
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 some 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. 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 this guy Ma Jun changed some Feiqian'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 bit 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 it. Fei Qian originally thought that building a ship 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 can be done with words, but the reality is that it taught Fei Qian 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 one hundred materials, more than three hundred to four hundred pieces of wood, or pieces, of various sizes were used, which were then trimmed 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, to build a ship that required twenty logs, the ancients would first calculate the quantity of materials used. A twenty-timber ship means that it takes
It took twenty pieces of wood to build the ship. Later, as the habit of naming slowly evolved, shipwrights used the number of pieces of wood to measure the size of the ship.
During the Qin and Han Dynasties, a piece of wood referred to an ordinary piece of ship wood. Such a piece of wood was generally about five or 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 carry the weight of two to three adults, which is about three hundred kilograms. Therefore, as the customs and inertia continue to evolve, the buoyancy carrying capacity of the ship's wood in the water is 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 can be used as a substitute. However, 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 on 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 ship's oars 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, but he only knew that his uncle and his second son could not identify it.
His uncle is his uncle, the high table and low benches are all made of wood...
So from a certain point of view, some simulation business 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 the players who played Three Kingdoms didn't go crazy on the spot...
Going further, you will find the car and boat that have been made into an entity.
Cars and boats 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 to go to Chang'an... Zhen'e went up the Wei and rode on the Mongolian to rush into the small river.
The ship and the sailors were all inside the ship. When the people of Qin saw the ship and no sailors, they were all astonished..."
Although this description does not directly mention vehicles and ships, "the people who sailed the ships were all inside the ships, and when the people of Qin saw the ships, 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.
.Also from another perspective, during the Eastern Jin Dynasty, the technology to hide the treadwheels was already available.
However, I don’t know whether it was due to technical secrecy or the war. It was not until the Tang Dynasty that vehicles and ships clearly entered the stage of history due to the needs of the Grand Canal.
When they got closer to the car and boat, Fei Qian could really feel the size of the boat. How can I put it, Chinese people just like big and white, uh, black and long, well, that's pretty much what it means 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. Looking at the comparison between Zheng He's ship of the Ming Dynasty and Columbus's ship, 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 forming a naval army when it is urgent, it is better to prepare for the rainy day earlier.
Taking 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 of Ma Yuan's invasion of Jiaozhi.
Waterways bear the important task of transporting people, horses and materials.
In the Han Dynasty, all boats used oars. The larger the boat, the more oars were used. But here is the problem. Think about the dragon boat racing athletes of later generations. How long does it take to train to reach a consistent paddle speed?
We 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. They can reduce the amount of training and have higher speed and explosive power when sprinting over short distances. Of course, if you are talking about long and long distances, then sailing is naturally the best way.
The carriages and ships built by Ma Jun also had sails, two sails, but now only the upright masts were standing. The canvases were folded up and stacked on top of the ship's planks. The wheels of the carriages and ships were on both sides.
In the middle, it is obvious that it is even uncoordinatedly large, and there are three oar holes on the left and right sides, probably to supplement power, or to assist navigation when the vehicle or ship overturns and cannot move.
"Let's try it out..."
Whether it is a mule or a horse, they all need a walk, and the same goes for ships. Fei lurked on the shore and watched the ships start to operate under Ma Jun's orders. The huge wheeled cart 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 wheeled vehicle hit the water surface, stirring up huge waves, and then provided the driving force to move forward. The vehicle and boat moved very fast on Kunming Lake. In less than half an hour, they had already completed nearly half of the circle.
Then he circled back again, stopped at the shore, and dropped anchor.
Everything seems right, but it doesn't seem quite right.
After the ship stopped at the shore, Fei Qian boarded the ship.
Sure enough, just as Huang Yueying said, due to the function of the flap, a large amount of water was brought out. 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 stagnant water in the cabin. Several boatmen are cleaning it in the cabin.
"Hmm..." Fei Qian frowned a little. After all, it had only been about half an hour after driving like this. If there was so much water in such a short time, it was indeed not suitable for use, even if someone was sent to clean up the water in the cabin.
, long-term immersion will also cause the bonded parts of the bottom of the boat to be easily damaged and corroded.
Is there anything that is not 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, although there aren't many, there are only five vertical ones. Could it be that there should be more? It doesn't seem right either.
Fei Qian and Huang Yueying mentioned the watertight cabin at the beginning. After all, this thing is a big weapon for ships, almost like a cavalry horseshoe. This thing actually existed in the Han Dynasty, but it was not popular. By the Wei and Jin Dynasties,
period, it is considered standard equipment for ships.
Oh, remembering what the problem was, Fei Qian couldn't help but laugh...
"That's it! The car rolled over, haha, this is a complete car rollover..." Fei Qian patted the large wheel plate next to the car 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, "What is the use of the overturned thing?"
Ma Jun gradually opened his mouth, then stamped his feet and sighed, "Oh! I didn't expect this!"
In fact, there are some things that, before being revealed, it seems that we have no idea what went wrong. Looking at the ship alone, there is no problem, and then looking at the car rollover, it is also no problem. Add the two together, and there is a problem. Find the problem with the ship,
It seems that nothing was done wrong. Checking the rollover again 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 to facilitate 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 there is no need to water 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 is not the holes and gaps in the ship that Huang Yueying initially thought.
The reason is. If the idea 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 function of lifting water when the car rolls over.
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 "
"Idiots" and "idiots" continued to persevere in their studies after being beaten to death, and this was how China's splendid civilization came to be.
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 made the most of it to see if there was anything that could be improved.
Come on, if you don't want to find Du Niang who is getting richer and richer, 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, it is worse than the Song Dynasty and the Ming Dynasty.
What components or structures?
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 very straight and high.
The sails under it are piled up in layers and piled up 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.
It has to be a little puffed up.
"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 navigation technology invention invented by mankind. The development of Chinese sails 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, and tailwind is the best direction for a ship to absorb wind. This is the most commonly used Chinese wishing phrase "bon voyage" and "smooth sailing".
However, the 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 human power 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 it is required that the sail should 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 can get some other pointers 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.
, we can only give up here and wait until Ma Jun produces the improved 2.0 version of the vehicle and ship and then take a look at it.
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 seen 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, "Do they look like sails? The wind should be the same size at this time, and the two flags are about the same length, but why?
The four-cornered flag moves slowly, but the pennant moves quickly? What would happen if the ship also used a triangular sail?"
Huang Yueying also raised her head and stared at the flag that was fluttering in the wind, "A triangular sail..."
