85_85996 Walking through the timber hoarding place, it is the sawmill, the whole changing yard is full of sawdust, ten steam engines drive ten sawmills to rotate rapidly, each sawmill is to more than 20 workers to feed, and then by more than 50 workers to transport the sawed wood, the whole sawmill has more than 1,000 workers.

The roaring sound of the machine, the sound of the trumpet, and the diffuse sawdust made Yang Tingjian see the glorious moment on the sea that China was about to come.

"Brother, I only gave you ten steam engines, why did you use them all for sawing wood, didn't you build a gantry crane?"

"If you don't know, this steam engine is too valuable, you don't have to waste it on the gantry crane, I have built the gantry crane, you only need to use the pulley set you brought to lift the planks, each dried plank is less than a thousand catties! There is no need for this gantry crane at all. ”

Yang Tingjian didn't plan to refute his brother now, and after looking at the ship in the dock, Yang Tingjian was putting forward his opinion.

There are 30 docks in the whole Longjiang Bao Shipyard, 10 each of large, medium and small, the large dock can build 5 or 6,000 tons of large treasure ships, the medium dock can build about 3,000 tons, and the small one can only build about 1,000.

When Yang Tingjian arrived at the dock, he couldn't help but shake his head, more than 1,000 workers were building ships, some of the ships had been completed, in Yang Tingjian's view, this was a big ship, completely inland flat-bottomed boats, the big ones were more than 100 tons, and the small ones were only a few dozen tons.

Yang Tingjian shook his head, but Yang Tingshu was not satisfied, and hurriedly explained:

"Bingru! What was built for my brother was Zheng He's treasure ship, with more than 1,500 materials for the big ones and more than 500 materials for the small ones. ”

(The quantifier appeared in the Song and Ming dynasties when the navigation was ahead of the world, a material is equal to ten cubic feet, the Song ruler or the Ming ruler, these two are not much different, a material = a stone = 92.5 kilograms, 500 materials = 46250 kilograms, displacement of 46.25 tons, for convenience, this article converts the material into tons when it is directly divided by ten.) ）

"Brother. Your ships can only be used for inland rivers, not for naval warships, and the foolish brother brought a lot of ship-like drawings this time. Please call the bow of the ship tomorrow, and we will discuss ......"

Yang Tingshu arranged a separate small courtyard for Yang Tingjian at Longjiang Bao Shipyard. There are three main rooms and six wing rooms, because Yang Tingjian plans to live in Longjiang Bao Shipyard for a while. That night, Yang Tingjian used the shipyard's radio to send a telegram, ordering Duan Jinsheng of the Huairou Iron and Steel Plant to take relevant technicians to the Ma'anshan area to build a new ironworks.

Shipbuilding requires not only a lot of wood, but also a lot of steel, if all steel is transported from Huairou in the far north. Shipping is just too expensive. Ma'anshan, which is only more than 50 kilometers away from Nanjing, is next to the Yangtze River, and the construction of a new steel plant there will play an immeasurable role in Yang Tingjian's voyage.

In the next time, Yang Tingjian did not have any rest time, first of all, he built a drying room according to the drawings, and if the wood for shipbuilding was used to dry naturally, it would take three years, and the weather in the south of the Yangtze River was dry and wet. It takes more time.

Yang Tingjian will definitely not use any stupid method of natural drying, and it is much faster to use the drying room to dry the wood of a house. It only takes three to five days. There is no technical problem in drying wood in the drying room, simply put, the whole drying room is the fire kang in the north, but this fire kang is built a bit large, and the combustion chamber is built in all four directions.

The drying room does not need to be worried about Yang Tingjian, Yang Tingjian and a group of ships are studying the drawings of the Victory every day, Yang Tingjian plans to start with the largest warship first, and hundreds of drawings must be thoroughly eaten.

Yang Tingjian, a modern man, also has his own methods, and he divides the labor of more than a dozen shipbuilding bows according to the technology they are best at. For example, there are special shipbuilding rudders and shipbuilding frames. There are covered boats.

Then they took their own drawings to study them carefully, and if they didn't understand, they came to ask Yang Tingjian. Yang Tingjian didn't understand it, so everyone discussed it together, and it took more than a dozen people about ten days to barely understand more than 100 drawings, and then they immediately started to make a 10-to-1 model.

And Yang Tingjian has a more important task, that is, the technical problem of installing a steam engine, fortunately, some sail warships are also equipped with steam engines, and there are places that can be used for reference, and Yang Tingjian has also carefully examined them, such as the Pennsylvania.

There is no problem in technology, but in order to use the practice, it must be practiced on the model, and now Yang Tingjian is the same as all the bow of the ship, staying in the model room every day and night, while checking the drawings, while making the model of the Zuò Victory.

Fortunately, Yang Tingjian bought some modern and accurate measuring tools, there are not many opportunities for rework, and the progress of the whole model is not slow.

Yang Tingjian has a five-axis CNC multi-functional machine tool imported from Germany, and there is no problem in processing propellers with a diameter of two meters, and the material of the propeller can also be made of bronze and steel, and the diameter of the propeller can also be calculated according to the formula.

The capital calculation formula for the propeller is: n=c(pd/d5)1/3, for example, the all-aluminum steam engine purchased by Yang Tingjian weighs more than three tons, the power is pd=1225kw, and the calculated propeller diameter is 1.2 meters. (This is too professional, the fallen leaves are Baidu, there are many formulas, such as the propeller speed formula, the propeller load calculation formula, etc.) ）

Yang Tingjian stayed in Longjiang Bao Shipyard for a month, until Lu Jianxing sent a telegram that they had arrived in Yangzhou, and now Yang Tingjian had no choice, he could only return to Yangzhou immediately with the four guards Wishing you prosperity, and Yang Tingjian explained to Yang Tingshu at the time of leaving, first build two first-class warships, and do not install steam engines.

These two first-class warships are mainly used as training ships, the blue navy is not built overnight, it is absolutely impossible without enough navigation talents, Yang Tingjian has already planned in his heart, this time he returned to Yangzhou, and immediately opened a navigation department in the Huben Military Academy.

The Huben Military Academy has now begun to take shape, and there are already a command department (advanced class), an artillery department, an infantry section, a logistics section, plus a navigation department, the Huben Military Academy is already a complete military academy, and they will be the most powerful weapons in Yang Tingjian's hands.

By the time Yang Tingjian rushed back to Yangzhou, Xia Mengqi had already arranged a qiē in an orderly manner, and tens of thousands of soldiers of the Tiger Ben Army had already moved into several military camps inside and outside Yangzhou. Shen Lian's city defense division was stationed in Yangzhou City, and three field divisions were stationed in the Huachi military camp five miles away from the warehouse outside Yangzhou City.

The firearms workshop and the four-wheeled carriage workshop were temporarily placed next to the warehouse, and these workers who went south with the Tiger Ben Army have now all become construction workers, and they are building their own factories together, money is not a problem, and Yang Tingjian now has more than 20 million taels of silver.

……

[The choice of fallen leaves is the British battleship level 1 to 6, because the British battleship has been tested in countless naval battles, and it is they who win in the end, and the battleship that has been in war for a long time is a few points behind.

Falling leaves know that there must be brothers who like other sail warships, such as the Trinity Holy of Spain, the Pennsylvania of the United States, and the flying Dutchman of France and the Netherlands, but the last laugh is the sail warship of the empire on which the sun never sets.

No matter what sail battleships the brothers like, please support the fallen leaves, monthly passes, rewards, and recommend sending it up, and soon the BB bomb will start bombing. (To be continued).
