Chapter 1920 Transplant problem, Sail evolution
The lighting up of any technology tree cannot be done by just talking about it.
Fei Qian has a lot of things in his mind, but limited by the sky, the earth, and people, many things can''t be made at all, can''t be used, and even have no substitutes.
Such as a boat.
There are naturally things that are much more advanced than cars and boats, but can they be built?
Even the simple combination has 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 for the time being...
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 from the Western Han Dynasty not being passed on to the Eastern Han Dynasty. In the past, some technical documents were not preserved, but some literary and descriptive languages ??were mostly used.
In the Han Dynasty, building boats appeared, and there were a large number of auxiliary ships, such as 艨艟, to assist in combat operations, and there were even special positions for generals and captains, such as "General of Louchuan", "Lieutenant of Louchuan", etc., which proves that In fact, in the Han Dynasty, especially in the Western Han Dynasty, the emphasis on and use of ships was still very good.
But after the Eastern Han Dynasty, because Liu Xiu and most of the emperors of the Eastern Han Dynasty after Liu Xiu adopted a contraction policy, the Lingqu 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 Feiqian is currently in Chang''an, and he can''t find any full-time boatman.
Fortunately, the arrival of Ma Jun has changed the embarrassing situation of Fei Qian''s research on ships.
After all, the Huang family is not very good at the research of ships, and there are many things that they don’t know much about. With Fei Qian, who is more half-watered, it is inevitable that they will sway a lot when combined.
For shipbuilding, it doesn’t mean finding a few pieces of wood, sawing, planing, and nailing. Fei Qian originally thought that building a ship was not a big deal. After all, it was not like the mechanical iron-clad ship of the later generations. Improving the existing wooden ship should be a job that can be done by lip service, but the reality is to give 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 of about 100 materials, more than 300 to 400 pieces of wood, or pieces, of different sizes are used to build a wooden boat of about 100 materials. Eventually it becomes a ship.
The so-called ship material is not the carrying unit, but the quantity of wood used in shipbuilding.
Ancient ships were built with wood, and a ship needs many pieces of wood. For example, to build a ship that requires twenty pieces of wood, the ancients would first calculate the amount of materials used. A boat of twenty materials means that it takes twenty pieces of wood to make the boat. Later, with the gradual evolution of the habit of addressing, shipwrights used it to measure the size of a ship, and calculated it by the amount of wood used.
During the Qin and Han Dynasties, material refers to an ordinary piece of ship wood. Such wood is generally about five or six meters in length and about twenty or 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 300 kilograms. Therefore, with the continuous evolution of customary inertia, the buoyancy capacity of the ship''s wood in the water is gradually used to calculate the size of the ship.
But with the passage of time, and the problem of inheritance of technical words, in the Song Dynasty, one material became a unit of volume again, and one material was equal to ten cubic feet (Song Chi)...
Therefore, the embarrassment of China''s technological inheritance has emerged. Those who know how to do, those who don''t know how to speak, and those who know how to speak, may not know how to write, and those who know how to write don''t know how to do it. A large number of confusing quantifiers and descriptions appeared, and in the end it was cloudy and chaotic.
If only one or two small models are to be built, then the pond in the backyard of the Hussar General’s Mansion is enough to replace it, but if one is to do a one-to-one physical research, then the space of the General’s Mansion is too small. Therefore, Fei Qian surrounded a corner of Kunming Lake and used it exclusively for Ma Jun to do research on ships.
When I arrived at the shipbuilding workshop here in Kunming Lake, I was surrounded by all kinds of wood.
"Straight cedar should be used for masts, camphor trees for beams and slats, miscellaneous for shallow boards, elm for rudders, elm for closing sticks, juniper for oars, and oak for oars..." Ma Jun led the Fei Qian and Huang Yueying walked forward, explaining to the piled wood on both sides, "Wenzhuya has strange wood, the material is fine, smooth and tight, heavy and stain-resistant, it will not crack when dry, and it will not rot when soaked. There is no choice... 』
『Oh...uh...』
Fei Qian could only echo with some incomprehensible voices, pretending to be an expert. After all, Fei Qian couldn''t identify most of the wood that Ma Jun was referring to. He only knew that his uncle and second uncle were both his uncles, and that 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 deal with 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. A kind of wood can''t be made, so the players who play the Three Kingdoms are afraid that they don''t go crazy on the spot...
Going forward, it is the vehicle and boat that has already been made into an entity.
Historical vehicles and boats probably first appeared in the late Eastern Jin Dynasty. It is recorded in "Zi Zhi Tong Jian": "Wang Zhen''e led a water army from the river into the Wei to approach Chang''an... Zhen''e went back up the Wei, and took the Mengchong small ship. All the sailors were in the ship. The people of Qin saw the ship. Furthermore, those who did not sail the boat were astonished as gods..."
Although this description does not directly mention vehicles and boats, but "all boaters are in the boat, and the people of Qin saw the boat and there were no boatmen", which shows that no one saw oars at that time, so they were very surprised to see that the boat was moving without oars. . From another point of view, at this time in the Eastern Jin Dynasty, there was already a technology to hide the tread wheels.
But I don’t know whether it was because of technical secrecy or because of the chaos of war. It was not until the Tang Dynasty that vehicles and ships clearly entered the stage of history because of the needs of the Grand Canal.
When the vehicle and boat approached, Fei Qian really felt the size of the boat. How to put it, Chinese people like to be big and white, er, black and long, um, that''s about it anyway. Ma Jun has also inherited the fine traditions of China. Although it is said to be an experimental work, it does not mean to be modeled at all, and it is quite large.
Fei Qian had some rough impressions. Looking at the comparison between Zheng He''s lucky boats and Columbus''s boats in the Ming Dynasty, it was as if Brother Yao and Brother Changjiang were standing together. Pursue.
It''s a pity that the **** Minister of Military Affairs...
Fei Qian took a deep breath.
If the south of the Yangtze River is to be controlled in the future, the navy is naturally indispensable. Instead of thinking about forming a navy when the fire is imminent, it is better to plan ahead 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 to Jiaozhi, and once again get through the situation that Ma Yuan entered Jiaozhi. The waterway undertakes the important task of transporting people, horses and materials.
In the Han Dynasty, all ships used oars. The bigger the ship, the more oars it needed. But here lies the problem. Think about how long it will take for future generations of dragon boat racers to train to achieve a consistent paddle speed? You must know that if there are so many oars, if the speed is different, let alone forward and backward, the oars can be smashed into a ball by themselves.
Car boats make up for this problem, can reduce the amount of training, and have higher speed and explosive power during short-distance sprints. Of course, if it is a long distance, sailing is naturally the best.
The vehicles and boats built by Ma Jun also have sails, two sails, but now only the masts stand upright, and the canvases are all put away, stacked on top of the boards. The turning wheels of the car and boat are in the middle of the two sides. Obviously, they are even too big to be coordinated. There are three oar holes on the left and right sides, which are probably used to supplement power, or the turning wheels of the car and boat cannot move. It is sometimes used to assist navigation.
『And try it out...』
Whether it is a mule or a horse, they all need to be taken for a walk. The same is true for ships. Fei Qian came ashore and watched the ships start to operate under Ma Jun''s orders. A large amount of water splashed, left the shore, and drove towards the interior of Kunming Lake.
The tumbling wheeled cart hit the water surface, stirring up huge waves, and then provided the power to move forward. The speed of the car and boat on Kunming Lake was very fast. In less than half an hour, they had already traveled nearly half a circle. Then he circled back again, stopped on the shore, and dropped anchor.
Everything seems to be right, and it doesn''t seem quite right.
After the ship stopped on the shore, Fei Qian boarded the ship.
Sure enough, as Huang Yueying said, because of the function of the flap, a lot of water was brought out, not only the obvious water splash marks on the deck, but also the water in the cabin can be seen when the upper deck is lifted. There is also some stagnant water in it. Several boatmen are cleaning up the cabin.
『Hmm…』 Fei Qian frowned a little. After all, it only took about half an hour to drive out like this. If there is so much water in such a short period of time, it is indeed not suitable for use. Even if someone is sent to clean up the accumulated water in the cabin, long-term soaking will cause the bottom of the boat to stick. The parts are easily damaged and corroded.
Is there something that is not done well?
The technology of overturning is very mature. After all, many places are used to irrigate farmland. Even the second generation of overturning and the improved version of the bobbin car are used, so it is basically transplanted to ships. Technically speaking, there should be no difficulty. Yes indeed…
etc.
Fei Qian suddenly felt that he had grasped something, but couldn''t remember what it was for a while. He touched the back of his neck in depression, frowned, looked left and right.
An infiltration-proof watertight compartment?
There are also, although there are not many, there are only five vertical ones. Could it be that there should be more? It doesn''t seem right either.
The watertight cabin was mentioned by Fei Qian and Huang Yueying from the very beginning. After all, this thing is a big killer for ships, almost like a cavalry''s horseshoe. In fact, this thing also existed in the Han Dynasty, but it was not popularized. In the Wei and Jin Dynasties, it was regarded as the standard configuration of ships.
Oh, remembering what the problem was, Fei Qian couldn''t help laughing...
"I see! Overturned, haha, this is totally an overturned vehicle..." Fei Qian patted the large wheel board next to the vehicle and said with a smile, "That''s the problem! 』
Huang Yueying froze for a moment, then seemed to be thinking a little bit.
Ma Jun frowned a little, obviously not quite understanding.
Feiqian laughed loudly, "What''s the use of the overturned thing?" 』
Ma Jun gradually opened his mouth wide, then stomped his feet and sighed, "Oh! Someone didn''t expect this place! 』
In fact, there are some things, before they are revealed, it seems that they don''t know what went wrong at all. Just look at the ship, no problem, and look at the overturned car, if you add the two together, there will be a problem. There seems to be nothing wrong with the problem of finding the boat, and checking for overturning is the same as before, and there is nothing wrong with it.
But here lies the problem. The original purpose of the rollover is to raise water from a low place to a high place to facilitate irrigation...
That''s why this car and boat have such a big splash when it is moving!
Car boats need power to move forward, and they don’t need water to irrigate the ship itself, but the wheels made strictly according to the rollover standard, can the amount of water not be a problem? It''s not because of the holes and gaps on the boat that Huang Yueying thought at first. If your thinking is wrong, you will naturally not be able to get out. Therefore, it is actually very simple to solve this problem, that is, to remove the original water lifting function of the overturned car.
Of course, from the perspective of God, you will think that this is also a fool, and that is also a fool, why can''t even think of such the simplest and most basic things, but in fact, in the history of China, most of the inventions and creations are these " After the "fool" and "idiot" were beaten to death, they still persisted in their research, and only then did China''s brilliant civilization come into being.
Ma Jun was in a hurry to modify it by himself, but was stopped by Fei Qian, "Leave this matter to the craftsman... Come, let''s look at other things..."
Fei Qian didn''t have time to come and stare at the shipbuilding workshop of Kunming Lake every day. Since he came here, he naturally used it as much as possible to see if there is any room for improvement.
Come on, if you don’t go to 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, what parts or structures are worse than those in the Song and Ming dynasties?
There are keels, watertight cabins, planks, parapets, sculls, oars, rudders, sails, anchors...
It seems that if there are ships now, there are also ships in later generations, and those ships in later generations seem to have them now.
Fei Qian walked slowly around the ship, and then stood in front of the sail.
The mast is very straight and high.
The sails under it are layered on top of each other and piled up under the mast.
Fei Qian pointed to the sail and said, "Pull it up and have a look..." There is no wind in Kunming Lake at the moment, so there is no big problem if you just pull it up.
Very traditional, the rectangular sail is fixed by five or six crossbars and ropes in the middle of the sail. Although Feiqian standing on the boat did not feel any wind, there is still some breeze in the air after pulling it up. Gotta puff up a little.
"Okay, let''s put it down..." Fei Qian noticed that the upper and lower bars of the sail cannot be moved, which means that the sail can actually achieve its maximum effect when the wind is down. Usually, oars and There are many sculls, so there is the battle of Chibi. Does Kong Ming have to borrow the east wind?
Using 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 Huaxia Fengfan has both similarities and differences with other civilizations in the world.
As we all know, it is best for the wind to blow from the stern of the ship, because it is downwind, and downwind is the best wind direction for a ship to absorb the wind. The most commonly used words in China''s blessings are "best voyage" and "best sailing".
However, the wind in nature comes from all directions. When the wind is headed, the wind force becomes the resistance of the ship''s progress. Therefore, the ships of the Han Dynasty can only furl the sails and use manpower instead.
In order to make full use of the wind coming from the side, the direction of the sail must be adjustable, that is, it has a certain angle with the incoming wind, and then it can generate a force perpendicular to the wind direction, which can be decomposed 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 immediately called a few craftsmen as if he had found a treasure, and started to improve the sail, and then followed Fei Qian closely to see if he could learn from Fei Qian. Get some other pointers over there.
But it''s a pity that Fei Qian himself is half full of water. All the impressions about wooden boats come from the Internet and film and television of later generations. In fact, he doesn''t know anything about specific practices, so after two more circles, there is no follow-up inspiration. , we can only let it go, and wait for Ma Jun to make the improved version 2.0 of the car and boat.
When Fei Qian and his party returned to the General Hussar''s Mansion, just as they got off their horses, Fei Qian saw the flag waving at the Yaqian Gate of Hussars Mansion.
Seems to have read somewhere that spinnakers are more applicable than quadribs?
『Husband...』 Huang Yueying walked up 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 should be the same, and the lengths of the two flags should be about the same, but why does the four-corner flag move slowly and the three-corner flag move quickly? What if triangular sails are also used on board? 』
Huang Yueying also raised her head, staring at the flag fluttering in the wind in front of the government office, "A triangular sail..."
