Yang Rui is very sure that shipbuilding will have a bright future, Xu Huafeng with the trust of the past, and no longer question, although he wants to say that the annual shipbuilding volume of Japan's shipbuilding industry is hovering around 150,000 tons, but people have a fleet of more than 100,000 tons, more than 1 million tons of merchant ships, these fleets and merchant ships, the annual maintenance cost is enough for those shipyards to toss.

He let go of this section in his heart, and saw that Wei Han and the others in the room were still discussing the ship type, and remembered a mistake of Chen Quartz just now, and corrected: "Quartz just said that the cost of using the diesel engine is low, 0.16 kilograms per horsepower, which can only be achieved under the condition of supercharging." If it is not pressurized, according to the estimation of the tractor in the real room, the fuel consumption per horsepower will exceed 0.2 kilograms, and there will always be waste when it is actually used, that is, the silver consumption per horsepower per ton will exceed six cents, close to seven cents. This is a blessing thanks to the high-pressure oil pump, without the high-pressure oil pump, it is impossible to be so fuel-efficient. ”

He saw Yang Rui surprised, and said with a smile, "Don't worry, he has also underestimated the coal consumption of the steam engine, how can there be standard lump coal sold now, the unwashed coal has a lot of impurities, and from past experience, this coal consumption is also more than nine cents of silver, close to one cent or more than one cent." Hey, the experience of the new graduates is always worse, and they often estimate the situation to be better than the reality, but this is fine, now they are full of energy, and when the wall is slammed, then they will be capable. ”

The high-pressure oil pump is the core technology of the diesel engine, just like the abandoned turbocharger, and Yang Rui can only roughly draw the style and principle of the oil pump, as for the specific implementation. I just don't know, and now that I heard that the oil pump problem has been solved, he asked with a smile. "How, doesn't it mean that the precision of the coupling should reach 0.0 millimeters and microns?"

"Nowadays, the accuracy of the oil pump coupling should reach 0.001 millimeter, that is, 10 microns or even finer, and the solution is very ingenious that a student came up with!" Xu Huafeng was very satisfied with his admiration, but after speaking, he was still unwilling, and said again: "But even so." The oil pressure of the oil pump is still not high, only twice the injection pressure of the gas tank, one hundred and forty standard atmospheres. Fourteen megapascals only, so the combustion chamber can only be designed to be semi-combustion. If the accuracy of the coupling can be improved to 40 megapascals, the efficiency of the diesel engine will be even higher. ”

Yang Rui couldn't figure out the difference between 14 megapascals and 40 megapascals. He only knows how to put questions and ideas forward. The specific implementation is just left to the people below, and there is no detailed understanding of how the solution is ingenious, asking: "Now that the Germans and Americans are asking about this thing, how did you reply to them?" ”

"How to reply...... Xu Huafeng said with a smile, "Just show them the number of hand-ground couplings, and tell them that this is a matter of seeking one in a thousand, they want to learn, and we will teach them if they spend money." But if you can't learn it, then you can rely on your ability. Wait until they enter this alley. It may not come out. Xu Huafeng is very confident in the ingenuity of the coupling precision solution, he is confident, and then said, "But while we talk about how high the scrap rate of the coupling is, we are shipping tractors to the United States one by one, and the selling price is not too high, I am worried that they will see the problem." ”

"There is no way around this, it has to be scaled up to ensure the continuous development of technology. The technology is completely secret, the principle is known to everyone, and the difference is only the implementation experience, in other words, just the difference in the cost of implementation. We do not produce diesel engines on a large scale, but put the technology on the shelf, then after more than ten years, we will find that the market has been occupied by products with worse technology, and then it will be too late to regret it, you must know that there is no market, you can not continue to invest in research and development. Yang Rui said that many leading technologies in later generations were defeated by low technology, and he was very sure of the previous adjustment, that is, to start mass production of diesel engines using high-pressure oil pumps, "We not only want to build tractors to tow, but also change all marine engines below 1,000 tons to diesel engines." ”

Yang Rui's decision made Xu Hua speechless, and he said: "The cost of the river boat is going up again!" What if Mobil raises the price of diesel? ”

"The increase in the price of diesel is just the same as kerosene, after all, diesel is now only a by-product for Mobil, and the sales volume is very small." Yang Rui said, "Besides, according to our negotiations with Rockefeller, in addition to Germany's Shandong and Russia's North Manchuria, the whole country will also give him the right to give him the diesel monopoly, who will ask him to borrow money?!" As for the increased cost of ships, the state will subsidize it, and the price difference between diesel engines and steam engines will be flattened. ”

"Prospecting rights outside of North Manchuria and Shandong!" Xu Huafeng exclaimed, "This ...... That's a lot of range! When the time comes, once public opinion knows about it, it will turn the world upside down. ”

"What are you afraid of, can you dig up oil?" Yang Rui asked rhetorically, "Public opinion will not make much trouble, after all, oil is very strange to the Chinese people, and then we can also find a few experts to go out to refute the rumors, let's just say that my country is an oil-poor country according to the geological situation." ”

Yang Rui's method taken from later generations made Xu Huafeng amazed, but he was still worried: "What if it is dug up?" ”

"Can't dig it out! It's just coming out, it's all small oil fields, and it's not worth paying attention to. Yang Rui affirmed, "You said that the Germans want oil pump technology, what happened to their submarines over there, the Germans didn't make a stumbling block, right?" ”

"Nope." Xu Huafeng is still lamenting that most of the country's prospecting rights are gone, "The Germans don't pay attention to submarines at all, and according to the intention of Navy Minister Tirpitz, submarines should not be built in the first place." Now they have supplied us with a submarine of 500 tons, which costs more than two million marks. How can we build submarines? Although this thing is not expensive, it will cost more than 500,000 US dollars for one. ”

"It's not decided yet." Yang Rui also didn't understand how many submarines were needed, "If the technology is mature, you can buy two or three submarines in Germany, and then like the Germans, you will start to build submarines in batches on a large scale after the shipyard is built." Always look at how others make it, master the technology, or build it yourself. ”

"The Germans built five or six submarines, two submarines each. We have to learn. A minimum of three batches is required to achieve the same level. Xu Huafeng thought about the situation in Germany, "But where are we building?" Is it placed in Jiangnan Shipyard? ”

"No, Jiangnan Shipyard is still a commercial shipyard. It should be placed in Wuhan. It's a pity that it's too far from the sea, so it's better to put it in Nanjing. Yang Rui thought about the location of the three shipyards, and there was no suitable one at all. In the future, the military shipyard will be set in Nanjing, where ships below 10,000 tons can enter during the dry season, and if they exceed 10,000 tons, they will have to wait for the wet season. Speaking of the shipyard, he couldn't help but think of the time when he would build a 50,000-ton aircraft carrier in the future. So where should the shipyard be? It seems that Qingdao can only be snatched from the Germans at the time of World War I.

He thought of the aircraft carrier, and Xu Huafeng thought of the fleet, he asked. "If so many submarines are built, and the navy doesn't add a ship, is this unreasonable?"

"Navy?!" Yang Rui disdainfully, "If it weren't for this, it would have to be." I think it's time to disband. ”

At the end of last year, the General Staff had already sent Wen Shude to monitor the navy. This former outsider and traitor of the Qing Dynasty appeared in front of the admirals so proudly, which made the original captains very disdainful, so they all pretended to be loyal to Guangxu, and all of them were sick, leaving only a piece of chicken feathers for him to clean up. The captain is not there, the officials on the ship are also not cooperative, and the general rear has reduced the salaries of senior officers, so that all Wen Shude can do now is take care of the ship. The daily training of the fleet has not been formalized.

"Don't talk angry, the fleet can be rebuilt after the first afternoon. And it is not easy to have the scale of today. The defeat of Dadonggou was not the fault of the Beiyang soldiers, if the princes of the original court did not die so badly, then the naval battle might not have reached that result. "My brother died because of the failure of investigating Beiyang, and the parties involved in the bombing case have died after so many years, Xu Huafeng's resentment against Beiyang has become extremely light, and from the perspective of his generation, the country must have a navy, and he often says good things to Beiyang, "The navy also wants to build its own ships, and I think it is the same as submarines, starting from 2,000-ton cruisers in batches on a large scale, one to two ships in each batch, and also in three batches." One and a half thousand taels is counted, and five ships are seven and a half million taels. ”

"It can be built, but the budget for each ship is added to 500,000 taels, and 10 million taels are gathered, how about building a steam turbine ship? We can learn as we build and master the steam turbine technology. Yang Rui emphasized. Diesel engines for submarines, steam turbines for warships, and gasoline engines for aircraft are the focus of research and development.

"Adding 500,000 must not be enough. At present, destroyers and light cruisers with ordinary power of less than 5,000 tons, with a speed of 11 or 2 knots, need 300 per ton to build themselves, and 500 per ton to build for Japan like Hubei; If the speed goes up to twenty knots, the price will rise to seven hundred taels per ton; If the speed exceeds thirty knots, it will be two thousand taels per ton. If you want to install a steam turbine on a cruiser, the speed will naturally be more than thirty knots, so that a two-thousand-ton cruiser will cost at least three million taels. ”

Xu Huafeng was extremely familiar with the cost of warships, and knew the importance of the 'three engines' under Yang Rui's indoctrination, and he added: "The patents of steam turbines are basically monopolized by the Englishman Parsons, and there are also many patents for reduction gears. In order to avoid these before, Jiangnan Shipyard bought the authorization of the impulse steam turbine of the American Curtis Marine Company, but this technology is not immediately mastered, and the technology of the boiler is also very important.

Looking at it now, the difficulty of the 'three engines', the diesel engine is mainly in the oil pump grinding accuracy and the material of the exhaust gas pressurization, the gasoline engine is the heat dissipation of the engine, the steam turbine is the most complex, not only the high-temperature wear-resistant materials, but also the boiler technical problems, the problem of reduction gears, is also extremely complicated, although you have explained the metallurgical real room to try the alloy steel, but there is no specific formula, then we can only try every formula and every formula, there are no ten or eight years, to create a qualified heat-resistant and pressure-resistant alloy, In my opinion, it is impossible, and the cost of it will not be much less than building a ship. ”

There is a special chapter on high school physics about heat engines, steam turbines, gas turbines, and even jet engines, but the introduction is very simple, just draw a few pictures, have a few photos, and talk about what alloys are used in these engines. As for the square of the alloy, how to make annealing and tempering, etc., there is nothing. For steam turbines, Yang Rui only knows what alloy the blade is and what alloy the shaft is. Although these were sent to the Dao Shi yàn room, after a few years, there was no movement at all.

"Three million taels for a two-thousand-ton cruiser. Why is it so expensive? Yang Rui said, "I remember that the 2,600-ton cruiser that Sa Zhenbing ordered in Britain cost only 200,000 pounds, but the speed was slower, only 20 knots. ”

"That's because they are greedy, but now these ships in Beiyang only have a speed of more than a dozen knots, and they really have to order a ship of thirty knots. That's also a mismatch for fast and slow. Xu Huafeng said: "The cruiser they ordered in Britain has only 6,000 horsepower, and we want to build a steam turbine cruiser." The horsepower is nearly 50,000 horses, which is eight times that of them, and the price is high here. It is necessary to rebuild something smaller, say a thousand tons. The price estimate is going to be 1,800 taels per ton. And if it is larger, like a battleship, the speed should not be more than 30 knots, only about 244 or 5 knots, and the price can be as cheap as seven or eight hundred per ton. ”

"Oh......" Yang Rui meditated on the cost of a fleet of more than 30 knots, "A 100,000-ton fleet is calculated at 1,000 taels per ton." Then it will be a billion taels, and a million tons is ten billion taels! It's so expensive. It's too expensive! ”

Xu Huafeng didn't understand what Yang Rui said again, he estimated that Yang Rui was envious of foreigners being rich, and he was just smiling at the moment, in fact, he didn't understand why Yang Rui valued submarines so much, the cost of submarines was actually not low, 1,600 taels per ton, fortunately, this kind of ship was not built much. After thinking about it, Yang Rui had already recognized the reality, and returned to his incomparably large desk with vigor, looked at Wei Han and the others and said, "Have you finished discussing?" Without waiting for a few people to answer, he said: "Since the cost of diesel engine oil is low, then the inland river boat should be changed and all equipped with diesel engines, so the increased grid will be subsidized by the state." Okay, that's it for now, and then let's talk about the results of your discussion. ”

"Your Excellency," Wei Han hadn't finished discussing it yet, but now he had to say some questions, "Class B standard ships are built in one year with the main engine and three years with the hull, which is cheap, but if it is really built, the reputation of the Jiangnan Bureau will be gone." ”

"This is not that we cut corners, but that we get what we pay for, fifty taels per ton, which is only one-third of the price of a normal merchant ship, and it is impossible for the person who bought it not to know that this kind of ship will be used soon." Yang Rui said. "Standard ships in wartime were built because they were in wartime, and if it weren't for wartime, how could such ships be built."

"The ship can't be the same." Wei Han is very uncomfortable with industrialized batch shipbuilding, perhaps in his opinion shipbuilding is a very artistic thing, he fought again, "Since it is not bought by the government but by the shipowner, there will always be different requirements for different routes, and the shipowner has a lot of ideas. ”

"Brother Ji Qian, if you can't sell it, let it go first." Xu Huafeng interjected, "Just tell me whether these ship types are suitable or not, is there anything to change?" With such standardized production, can the shipyard adapt? Although this standard ship is built in three months, this is the minimum requirement. ”

"Lord Xu, a 6,000-ton standard ship can't be built in three months anyway, and it will take three months to rivet the rivets of the whole ship, and only 2,000 tons of this kind may be built in three months, but in this case, there can be no fewer workers, no less cranes in the shipyard, and cranes on the left and right sides of each slipway; The shipyard's original steam pumping machine also had to be replaced, and it took him nine hours to drain the water in the dock, while the electric pumping machine only took forty minutes......"

Wei Han is indeed always on the front line, and he is very clear about how to speed up, Yang Rui didn't want to listen to the details, but heard him say that it would take three months to work hard to rivet, and suddenly thought that the free wheel in World War II seemed to be welded, and now the welding technology is not up to par, and it is not fast to think about it. He waited for Wei Han to finish nagging, and then said, "Can you build a six-thousand-ton ship in five months?" ”

"Five months?" Wei Han couldn't be sure, he shook his head and said, "The lower officials have never made it, so it's really hard to guarantee." However, the beginning is always slow, and when the workers are familiar with it and the rules are clear, it will always be faster. ”

"Then you go back and discuss with the management of the shipyard how to adjust the shipyard and what to replace it faster than that. The experience of the Jiangnan factory will be directly used in the other two shipyards, give you a year, and after a year, you will come up with a specific plan, and then Nanjing and Hanyang will be built according to this plan. Yang Rui said, "You also see if the ship type is to be changed, anyway, we have only one requirement, that is, to build as much as possible, as far as possible to launch the water, in order to achieve this purpose, the shipyard, the ship type, must be adjusted." ”

Today is just a meeting, and Yang Rui feels that he has to personally order in order to do his best to do the best. He said about the shipyard and the type of ship, and then said: "You have seen the inland river transport ship, is it designed like this?" ”

"Done!" Wei Han Dao. "All diesel engines are also used, and Asia Oil has built more than 10 diesel engine ships in the Jiangnan Factory, that is, we have not installed diesel engines on ships of up to 1,000 tons. There is another type of boat that should be as exceptional as inland river boats, and that is the river boat. As we all know, the upper reaches of the Yangtze River from Yichang to Chongqing have turbulent currents and many dangerous shoals, and the steamers there have to be specially made. Not only should the draft be shallow, but the horsepower should also be large, and the ship is generally less than 1,000 tons. The horsepower is more than 3,000 horsepower, do we have a single diesel engine with 3,000 horsepower? ”

"Three thousand?" Yang Rui looked at Xu Huafeng, and the specific situation of the diesel engine was still the best for him.

"There are no three thousand horses." Xu Huafeng shook his head and said, "Now the largest single machine is only 1,800 horses. The 1,000-ton Sichuan River ship still uses a steam engine. The 500-ton Chuanjiang theory can be used with diesel engines. ”

Standard boats, river transport vessels, and finally the river boat. These were all briefly passed, and after greeting for a while, after Wei Han was sent away, Xu Huafeng said when there was no one, "Hear, his last words are to help the navy again, it turned out, really want to find a foreigner to be the admiral of the navy?" ”

"Cheng Biguang and Sun Wen have an excellent relationship. Otherwise, he could have been a commander. Yang Rui didn't care about Wei Han's last ardent expectations, in his opinion. The shipyard and the navy are all the way, and it is normal for them to help talk, "Sa Zhenbing and those people are still in Shanghai, saying that they want to keep filial piety to Guangxu, and they don't invite them." Chong'an's side told the U.S. minister what we meant last year, of course, he didn't say that he was looking for a naval admiral, but only said that he was looking for a naval consultant, and now they have recommended a few candidates......" Yang Rui took out a few brief resumes and handed them to Xu Huafeng, "If nothing else, I will probably choose one of these people." ”

Several resumes were of U.S. Navy colonels, the first one of which was a man named Robert. Kunz's, and the next one is a William. Applejack. There are two other people, but those two people drew a cross for Yang Rui, and it seems that he is satisfied with these two people.

Xu Huafeng said: "If the navy hires the Americans to be advisers, then Japan's antipathy towards us will be even greater, and the British will probably not like it." ”

"Even if I asked the Japanese Navy to be an advisor, they still resented us." Yang Rui replied, "Some people are born enemies, and some countries are born enemies, I didn't believe it before, but now I believe it." Britain and Japan are allies, and they will only stand on Japan's side of anything that happens in the Far East, unless it affects their vital interests. At this time, what we want is to stand in line, and we can't hesitate to please anyone. Because everyone is pleased, that is, everyone is offended. ”

"It's ......," Xu Huafeng put down the American's resume and said: "Then in less than two years, we and Japan will definitely fight, and I think we have to be careful in 14 years." ”

"Ahh 14 years? Yang Rui was surprised in his heart, he looked at Xu Huafeng and asked, "Why do you know...... Why did Japan go to war in 14 years? ”

"How could I not know," Xu Huafeng was sure, "In the past 40 years, Japan has been fighting every 'four'. In 1874 they fought Taiwan, and in 1884 they made a rebellion in Korea, if it wasn't for Yuan Xiangcheng's quick decision to repel the Japanese army, I was afraid that Korea would have been lost, not to mention in 1894, and as recently as 1904, they had a big war with Russia. These four wars are all related to us, even if in 04 it was with Russia, but it was also in the northeast. The year after that, it was the fourth day, and last year they didn't get anything, so it was normal for Japan to find an excuse to go to war with us again. ”

"1874, 1884, 1894, 1904, 1914...... not to mention that Yang Rui did not know that the Japanese had such a law, from the perspective of later generations, Japan's intervention in the Soviet Union in the early twenties was 1924, and in the thirties because of the financial crisis in advance, 918 was the prelude to 1934, and the 77 incident was the follow-up, and since then the Japanese have been out of control, he thought about this festival, and said with a smile: "This is actually the rhythm of the Japanese training the army, just like the Huns fought the grass valley hundreds of years ago, Those who graze their herds have to go in every winter to grab them. Mr. Huafeng, don't worry, this time the dog's day is coming, and they will not come back! (To be continued......)
