Datang Nongsheng

Chapter 743 To the shipyard

If it is said that the city in Datang has the strongest industrial atmosphere, then it must be Weinan.

It only takes more than an hour to travel from Chang'an to Weinan on the first mass-produced medium-sized steamer. This type of ship is built for the purpose of express passenger transportation, with a maximum load of only [-] shi, which translates to a draft of about [-] tons.

However, such a ship is equipped with two large three-cylinder steam engines as power propulsion, and its normal speed can reach more than 20 kilometers per hour. If it goes smoothly, it can even run more than 45 kilometers per hour, and it can reach nearly [-] kilometers per hour. , Running from Chang'an to the downstream waterway can basically achieve the speed of traveling thousands of miles a day.

Of course, it can be faster, but no matter how fast it is, safety cannot be guaranteed. In order to allow such a fast boat to travel on the waterway, the Weihe River even has to specially divide the fast boat and the slow boat.

Because the old ships will be slower to turn and avoid. With the lively scene of thousands of ships and sails on the Weihe River anytime and anywhere, it is easy to collide.

This steam-powered ship named "Prince" is Li Chengqian's special ship. It is divided into upper, middle and lower floors. The lower cabin is a workshop, the middle cabin is a room for rest, and the upper cabin is a small sightseeing The banquet cabin is luxuriously decorated, with more than 100 people on board, it doesn't look too crowded.

If it is a professional passenger ship, the internal structure may be simpler, just install a whole row of seats. In that case, one ship can transport hundreds of people. From the wharf in Xunyang County, you can reach Jiangling within three days. From Weinan Wharf, within three days, you can reach Dengzhou and Laizhou, within five days, you can reach Hangzhou Bay, and in about eight or nine days, you can reach Guangzhou City.

This kind of speed of traveling thousands of miles a day, in the eyes of people of this era, is already very fast, but in the eyes of Sun Xiangfu, it is still surprisingly slow.

In later generations, the train from Xi'an to Guangzhou is just a matter of one day. Now you don't stop day and night, and it takes eight or nine days to arrive, which is simply weak.

The boys of the Sun family all spent their childhood in Jiuyuan County, so they are not afraid of water at all. After they got on the boat, they are more familiar than Sun Xiangfu. Obviously, they have been on the Prince's ship before, and Sun Xiangfu doesn't need to look after them , they occupied the best view position and played with the telescope on the ship.

"Teacher, how is this boat built?" After sitting down on the sofa in the upper cabin, Li Chengqian asked Sun Xiangfu with some pride.

Li Chengqian has participated in the steamship from its first sea trial, to every subsequent sea trial, to its final shape, and to its decoration into what it is now. So far, the speed and comfort have not been comparable to it. After all, Li Shimin had previously There is no need for such a boat at the Anxi Protectorate's Mansion.

Sun Xiangfu nodded with a hint of admiration, and asked, "How many ships can it produce in a year?"

Li Chengqian replied with a smile, "You should ask how many ships can be produced in a month. After the technology is formed, we will manufacture all the parts in batches. Now, Weinan Shipyard has ten large production lines, five of which are for passenger ships. Five of them are used to build cargo ships, and they are basically assembled from manufactured standard parts to form ships. Each production line of passenger ships can build one every month.

The structure of the cargo ship is simpler. One can be produced in less than 20 days, and fifteen can be produced in two months. This year, it has only been mass-produced for three months, and more than 40 passenger ships and cargo ships have been produced.

However, at present, these small and medium-sized ships of [-] stone are all used in inland rivers and rivers for civil and commercial purposes, for letter and parcel delivery, and fresh goods delivery, etc., and the real all-steel warships and large ships sailing in the open sea, Manufactured in the Hangzhou Bay Shipyard, there are more sailing and shipbuilding talents there. "

When Sun Xiangfu supervised the manufacture of military equipment in his early years, he used this set of detailed decomposition, standard manufacturing, and assembly methods. Now it has been learned and used by various industries. It is more efficient and easier to do things this way.

This kind of small and medium-sized ship is not a battleship. Except for the bottom plate, most places do not need to be poured with steel plates. It is naturally simple to manufacture.

According to the output Li Chengqian said, I am afraid that in a few years, the ships on the rivers and lakes in the Tang Dynasty will have to change rounds. In this way, the efficiency of the entire passenger transportation and logistics will be greatly improved.

Sun Xiangfu asked again, "Can the shipping personnel driving such a steam ship keep up with the speed of the ship?"

Li Chengqian replied, "I'm a little nervous. The students of the Maritime Academy are all sweet and sweet, and the talents they teach are to be used in the ocean-going sailing business. Therefore, I want to set up a steamship pilot on the side of the Lantian Technical College." class, train the drivers."

Sun Xiangfu smiled and said, "One class is definitely not enough, we can separate it out and set up a special school with thousands or tens of thousands of training. In the future, where we need to use similar talents, there will be more and more people. many."

Li Chengqian thought so too, now there are only dozens of ships, and the hundreds of people trained before have all been used. In the future, I don’t know how many such ships will need people to drive, so he nodded and said, "What the teacher said is , Turn around, I will ask Yuwen Shilang to take care of this matter."

Here, Li Ke thought of some ship runners on Shannan Road, and suggested to Li Chengqian, "We have to give priority to those sailors who have experience in sailing to learn. In addition, there is not enough one college in Chang'an, Jiangling. , there are more talents who are familiar with shipping.”

Li Tai also reacted and said, "Although there is a branch of the Nautical Academy in Guangzhou, there are also a lot of merchant ships and passenger ships going to the inland, so we also need to start training."

Sun Xiangfu laughed and said, "Then open three academies! In Tang Dynasty, there are not too many institutions that teach ordinary people skills."

The three of them laughed when they heard the words. At this moment, what they were thinking was not only about driving a steamship, but other industries seemed to be able to implement it in the same way.

Only Cheng Chumo felt a little depressed. Riding a horse to fight a war is something he can do, and driving a steamship is too high-tech, he can't.

Next to the Weinan Wharf is the Weinan Shipyard. After the Prince stopped at the wharf, a group of people on board went ashore and walked towards the shipyard. As soon as they entered the gate, Sun Xiangfu saw inside the No. [-] Dock, a The tall steel plate clad wood hull, since the carbon arc welding technology has not been developed yet, for the time being, this mode can only be used to build the hull.

This is a large steam cargo ship being developed and built by the Weinan Shipyard. Its draft, or load, should exceed [-] tons, which is about fifteen times larger than the 'Prince' they were on just now.

Moreover, its sailing speed will only be about 24% slower. According to the budget before construction, the average sailing speed on the river can reach about [-] to [-] kilometers per hour, [-] hours a day, [-] kilometers no problem.

As for the larger 4000-ton sea-going ships and naval battleships, they are built in the Hangzhou Bay Shipyard. With steam engines as power, they are not afraid that the ships will be too big to run. , all have a displacement of more than [-] tons, and between World War I and World War II, many steam-powered cargo ships with a load of [-] tons came out, and their upper limit is still very high.

However, shipbuilding technology has to be researched and developed step by step. At present, the [-]-ton cargo ship is only theoretically possible.

In any era, the development and construction of such a large ship is not something that can be completed overnight. So far, it has been built for more than a year, but the hull has only been poured out.

In the future, it will have to go through the process of repeated improvement and testing like the small and medium-sized passenger ships that are currently mass-produced before it can really launch into the water. It can be completed in five to ten years, which is considered fast.

And five to ten years later, maybe Datang's new generation of steam turbine engine will come out. Earlier, Sun Xiangfu talked about its principles. Now, it has already begun to be in the research stage, and the model machine is about to come out. It's done.

In fact, people who understand the steam engine usually think of some improvement models themselves. Later generations started to improve the steam engine and used it in industry. It took only a few decades until its appearance and popularization. However, they came into contact with science and formed a national learning system. The people of Tang Dynasty who studied the trend may not be stupider than the people of later generations.

Yang Shunshui is almost sixty years old. Although he comes to work in the shipyard every day, in fact, he can't control anything anymore.

The current shipyard is not only concerned about the design, the metal materials used for the bottom plate, the bearing strength of the keel, the application of the steam engine and even the circuit, the calculation of the bending force of the hull, etc., are not as good as he used to be. The master craftsman who designed and built wooden boats can understand it.

He just came to watch the young men in the shipyard work, as long as he could see their juniors build new boats and launch them, he would be very happy.

Therefore, Lao Yang, who had nothing to do, immediately spotted Sun Xiangfu and the others.

Li Chengqian has been going to the shipyard for a few years, Yang Shunshui is no stranger to it, Sun Xiangfu has not been to the shipyard for almost ten years, when Yang Shunshui saw him, he laughed regardless of his missing front teeth It will be ugly when you look up, but you will welcome me happily.

"When I came to the shipyard, I was so happy to see you grow old for the first time."

The two of them didn't follow the social fashion and greet each other. Instead, they directly held hands together and shook them vigorously. People who really have a deep friendship don't need politeness.

"I, I'm glad to see you coming. You haven't been here for more than ten years!"

Sun Xiangfu smiled and said, "I didn't come because you did a good job here. I don't need to come. There are still many people in Tang Dynasty who can't farm well. I need to teach them, so ah! I haven't been idle for years."

"You are doing great things that benefit the country and the people. I still know this old man, but I am useless now, and I can't help you much."

Speaking of this, Yang Shunshui was somewhat disappointed, while Sun Xiangfu smiled and said, "You have finished everything, what will your children and grandchildren do? You have to let them do more things and find out more advanced technology. It would be good to benefit more people in future generations!"

Hearing so much about Sun Xiangfu, Yang Shunshui laughed again with gaps in his mouth and said, "Hehe, you are right. Turn around, I won't be an eyesore at the shipyard anymore, and I will tell my grandchildren to study at home."

Li Chengqian said with a smile from the side, "You have to come to the shipyard too. With you here, these younger generations will work harder. If they don't slack off at your age, they will have no reason to slack off."

"Then, old man, am I coming to the shipyard? Or should I tell my grandchildren to study at home?" Yang Shunshui asked Sun Xiangfu in a daze.

Sun Xiangfu replied with a smile, "You don't have to worry about it, as long as you feel comfortable, you can do whatever you want."
