(The number of chapters is wrong, it should be chapter 113)

The results of Xu Jianyin and Chen Daoyuan's research are two things, one is a new type of small battleship, and the other is a new type of small submarine, and the reason why they studied these two things first is very simple.

With the current conditions of researchers, technicians, workers, and resources of the Weapons Research Institute, it is impossible to build a heavy battleship in one step, so it can only research and produce small battleships, and in the next ten years, aircraft have not yet become the master of the sky, aircraft carriers have not yet been born, and battleships will be the main ships of the navy, so the study of battleships is the most important, as long as the battleships are successfully developed and produced, then other destroyers, cruisers, frigates, etc. will not be a problem.

At this moment, Xu Jianyin pointed to the battleship model that had been successfully tested, and was introducing it to Wang Jundao, Ye Zuqi, and Sa Zhenbing: "Commander, this is the battleship we have studied according to your design drawings.

This battleship is 88 meters long, 13 meters wide, 5.5 meters draft, displacement of 3,300 tons, armed with three 'Piercing' 250mm naval guns, two in the bow are double-mounted, one in the stern, and six 'Piercing' 150mm rapid-fire guns as secondary guns, four in the bow and two in the stern, and ten 'Piercing' 55mm rapid-fire guns on the left and right sides as escorts.

It is powered by two vertical four-cylinder reciprocating steam engines and 14 coal-fired boilers that produce 16,000 hp and are expected to reach speeds of between 26 and 29 knots at the fastest speed. ”

Wang Jundao nodded secretly and said, "Yes, yes, it didn't disappoint me, by the way, how about the drum boilers, oil-fired boilers and steam turbines that I asked you to study?" ”

Xu Jianyin said: "The drum boiler has been developed and various data are being tested. ”

When Wang Jundao heard this, he was overjoyed, he originally thought that although he had his own design drawings and technical guidance, these power equipment would take at least several months to develop, but he did not expect that it would be studied in just over ten days, and he couldn't help but sigh in his heart, the wisdom of the Chinese is always endless.

Wang Jundao said: "Okay, in the afternoon, I will personally go to test all kinds of data, and strive to meet the expected standards as soon as possible, and in the future, the power equipment of all warships will be replaced by drum boilers, oil-fired boilers and steam turbines, and the speed will be greatly enhanced." ”

Xu Jianyin couldn't help but say: "Commander, since the duplex steam engine and coal-fired boiler are going to be phased out, why not just change our first battleship to new power equipment?" Then you can go in less trouble in the future. ”

Wang Jundao groaned for a long time and said, "Okay? ”

Xu Jianyin smiled confidently: "Since we can study a battleship powered by coal-fired boilers and duplex steam engines, we can study battleships powered by drum wheel boilers, oil-fired boilers and steam turbines. ”

Wang Jundao no longer hesitated, as Xu Jianyin said, anyway, we have to go to that stage, why not start with drum boilers and steam turbines at the beginning? Everything is difficult at the beginning, as long as you get off to a good start, you will save a lot of trouble in the future.

After thinking for a while, Wang Jundao nodded and said, "Okay, then re-study, I will come up with new design drawings as soon as possible, and you will also lead everyone to put forward new ideas." ”

Xu Jianyin said loudly: "Yes! ”

Wang Jundao looked at Daoist Chen, who had not spoken, and Ye Zuqi and Sa Zhenbing, who had already opened their eyes and were shocked beyond words, and said, "Then let's go and see the submarine model now." ”

The research of the battleship was led by Xu Jianyin, assisted by Chen Daoyuan, while the research of the submarine was reversed, led by Chen Daoyuan and assisted by Xu Jianyin, because as early as 20 years ago, Chen Daoyuan, who was only 28 years old, had already led researchers and machine workers in the Tianjin Machinery Bureau to produce China's first submarine, and successfully launched it in the Haihe River.

In the past 20 years, due to the lack of attention from the Qing political axe, the submarine cause has been stranded, but Chen Daoyuan has never stopped the study of submarines, although for various reasons did not build a new submarine, but the understanding and familiarity with submarines has reached an extremely high level, and it can even be said that his submarine thinking has far surpassed that of people of this era, and he has even studied a set of submarine construction and submarine combat theory.

The submarine design drawings given by Wang Jundao to Chen Daoyuan show a relatively avant-garde submarine, and many theories and knowledge are not possessed in this era, but Chen Daoyuan only spent three days, and he completely figured out the submarine design drawings and submarine theories handed over to him by Wang Jundao.

After that, Chen Daoyuan personally led the researchers to fight day and night, and it only took five days to get out the preliminary model of the submarine, which finally reached the expected level after repeated testing and modification.

In order to complete the research on the submarine, for more than ten days, Chen Daoyuan has rested for less than four hours a day on average, and now his eyes are full of bloodshots, but even so, he is still in good spirits.

Facing Wang Jundao and his entourage, he did not directly introduce the submarines he studied, but first introduced the important surnames of submarines: "Commander, two generals, with China's current situation, even if there is a ship technology provided by the commander, although these technologies are more than those of Britain, the United States, Germany, and other countries, China's industrial base is too far behind these countries, especially the construction of various warships, it is impossible to catch up with and surpass these countries in a short period of time, so when vigorously developing warships, we must find another way to win by surprise, And to be surprising, we have to start from two aspects, one is below the sea surface that the enemy can't see, and the other is the sky that the enemy can't control, for the sky, not my field of study, I don't have the right to speak, but for underwater, I have my own opinions, as long as we can develop a submarine with a good surname, then even if the navy's fleet strength is slightly inferior to that of other countries, as long as the submarine can be haunted at the bottom of the sea and play a decisive role at a critical time, it can also turn the entire naval war around, so a submarine, and sometimes even outnumbered several battleships. ”

Chen Daoyuan's words opened another door to the navy for Ye Zuqi and Sa Zhenbing, and they seemed to see the future war situation of the navy: the fleet on the surface of the sea is the right match, and the submarine on the bottom of the sea is the miraculous victory! Just now, the two of them have been deeply shocked by the new battleship researched by Xu Jianyin, and now they are deeply shocked by Chen Daoyuan's submarine theory, and the impact on their thinking is not small.

At this time, Wang Jundao said: "That's right, in the future, we must not only vigorously develop the submarine force of the navy, but also vigorously develop the air force, so that the entire sky will become our domain, and as long as we can establish an air base in an important port near the coast, or directly build an air base on a warship, we will be able to unscrupulously bomb the navy of an enemy country that is trying to invade our country from the sea. Now the most important thing for us is to develop the navy first, Lao Chen, you can introduce this submarine to everyone. ”

Of course, Wang Jundao is already developing the air force, although it is not possible for people to study aircraft for the time being, but with Xie Zhangtai, the father of China's airship, he has already let him develop a new type of airship, and it is only a matter of time before the aircraft comes out.

After listening to Wang Jundao's words, Chen Daoist nodded and introduced directly: "If this submarine is completed, it will be 25 meters long, The width is 4.2 meters, calculated according to the measured data, the deepest dive can reach more than 50 meters, the surface displacement is 550 tons, the underwater displacement is 435 tons, it belongs to small submarines, mainly used for torpedo attacks and the placement of mines, can be loaded with 10 to 15 mines according to the model, powered by compressed diesel internal combustion engine and battery, the maximum diving speed can reach 18 knots, the use of electrolyzed water equipment for oxygen supply, according to preliminary calculations, the maximum diving time can be up to 15 days. ”

Speed 18 knots, diving up to 15 days? This can be directly from Tianjin to Yuben, and then return to Tianjin from Yueben, is it so terrifying?

Sa Zhenbing and Ye Zuqi glanced at each other, both of them looked incredulous, Chen Daoist seemed to see through what they were thinking, and said with a smile: "This is only the maximum time for theoretical diving, which also needs to consider the fuel supply, oxygen supply, divers' mentality, freshwater food supply and other factors of the submarine, combined with these factors, you can dive for up to ten days." ”

Sa Zhenbing didn't think ten days was too short, he said: "Ten days is enough, as long as the submarines can be lurking in the water for ten days, then as long as there are a certain number of submarines, the foreigners' fleets will not dare to haunt China's coastal waters unscrupulously, because we can attack them at any time, and after the attack, they will have fled as quickly as possible." ”

Wang Jundao nodded with a smile and said: "That's right, as long as we can design the submarine, use new ceramics and other shells to prevent the adsorption of torpedoes, and make the submarine into the shape of a whale, once we sink to the bottom of the sea, it is difficult for the enemy to find our traces, of course, if you want to have a strong submarine force, the requirements for communication are the highest, at least to be able to keep the radio open at any time, now Britain, the United States and other countries have been vigorously developing radio technology, Britain has even been able to send wireless telegraphy across the English Channel, We must not lag behind, and I have already asked people to start researching it, and at the same time, we are also recruiting personnel from other countries in this field, and I believe that it will not be long before new communications technology will be developed, and then the combat effectiveness of the navy will be raised to a higher level earlier.
