Lin Fei smiled and asked, "Where is the design index low?" ”

Liu Daming said dissatisfiedly: "Why is it not low? The Japanese Hashidate, Matsushima and Itsukushima ships all have a displacement of more than 4,000 tons, the Takachiho and Naniwa ships have a displacement of more than 3,500 tons, and the displacement of our new warships is only 3,500 tons, isn't this low? ”

"There are also artillery calibers, the Hashidate, Itsukushima and Matsushima ships are all equipped with 320 mm caliber guns, and warships such as the Takachiho, Naniwa, Akitsuzu and Chiyoda also have 150 mm guns, while our battleship guns are only 120 mm caliber, isn't this low?"

"There is also the last key design indicator - speed, our design index is only 18 knots, which is not at all comparable to the Japanese warships, the Beiyang Fleet suffered a loss of too slow speed in the Battle of the Yellow Sea, our current design index is so low, will it not be a fiasco like the Beiyang Fleet?"

Lin Fei said with a smile: "You said so much because you were worried that we would not have an advantage in the face of Japanese warships, right?" ”

Liu Daming said in a loud voice: "Of course! I don't see any advantage in these design indicators! ”

Lin Fei said with a smile: "You don't have to worry about this at all, although our design indicators do not exceed the Japanese warships, we still have many advantages compared to the Japanese warships." ”

Liu Daming frowned and said, "What's the advantage?" Tell me about it. ”

Lin Fei said: "Do you still remember the scene when the Japanese shells rained down during the Battle of the Yellow Sea? ”

Liu Daming nodded and said: "Of course I remember that the guns equipped by the Japanese are called 'rapid-fire guns', which have a faster rate of fire than our guns, and we suffered a big loss during the naval battle." ”

Lin Fei said: "Yes, the most advantageous point of the Japanese Combined Fleet is the rapid-fire guns, although their Hashidate, Itsukushima and Matsushima ships are equipped with 320 mm giant guns, but this type of giant cannon has great flaws in design, and it cannot play a role at all in actual combat." ”

Lin Fei paused when he said this, then cleared his throat and said solemnly: "Since the advantage of the Japanese is the rate of fire of the artillery, then we will also use rapid-fire guns to offset the advantage of the rate of fire of the Japanese artillery!" ”

Liu Daming's face was full of suspicion and asked, "Do we have rapid-fire guns?" ”

Lin Fei nodded with a smile, then looked at Ling Xue and said, "Xue'er, how did the Vulcan plan for you before I set off?" ”

Liu Daming didn't wait for Ling Xue to answer, then hurriedly asked, "Vulcan plan?" What is that? ”

Lin Fei smiled: "It's our rapid-fire cannon plan!" ”

Liu Daming let out an "oh", turned his head to look at Ling Xue, Ling Xue looked at Liu Daming, then at Lin Fei, and said, "There are more situations to report, so I'll report separately when the meeting ends." ”

Lin Fei nodded, then looked at Liu Daming and said: "The rapid-fire cannon is one of our advantages, we also have an advantage in artillery shells, don't forget, we have cap-piercing shells that no country in the world has, and blasting shells filled with trinitrotoluene explosives." ”

"The explosives in the Japanese artillery shells are called 'Shimose explosives', the main body is picric acid, filled with incendiary agent, although the explosive power of picric acid is slightly stronger than that of trinitrotoluene, but trinitrotoluene can be poured into the shell under pressure after melting, and the charge density is larger, so the explosive power of the shell is stronger than that of the Japanese shell."

"There is also our fire control system, there is no fire control system on Japanese warships at all, and there is no stereo rangefinder as advanced as ours, so their shooting accuracy is definitely not as good as ours, artillery rate of fire, shell power and shooting accuracy, these are our three major advantages in the face of Japanese warships, and this advantage is not enough to defeat them?"

Liu Daming thought for a while and said: "If our artillery can't be studied, the advantages behind it will not exist, and I will personally go to see the Vulcan plan in person!" ”

Lin Fei agreed with a smile, and then continued: "As for the displacement and speed you said, although our displacement is less, it has little impact, and as for the impact of speed, it is even smaller. So we don't have the disadvantages you mentioned at all, and I have another plan, and if this plan succeeds, our advantage over the Japanese will be even more obvious. ”

Liu Daming hurriedly asked, "What is this plan?" ”

Lin Fei said with a smile: "We'll talk about this plan later, I'll continue to talk about building the hull of a warship, our warship is 90 meters long, 14 meters wide, and has a draft of 4 meters. ”

Everyone applauded repeatedly, Lin Fei said at this time: "Our battleship needs a loud name, the battleship is cruising in the sea, and our Chinese dragon is also infested in the water, in my opinion, our battleship is called 'Dragon class', and the ship type is a cruiser, so the official name of the battleship is 'Dragon class cruiser', the first ship is called Tianlong, and the second ship is called Yunlong." ”

At this time, Yu Xier spoke, and he said: "The class name is the name of the first ship, since the first ship is called Tianlong, then this class cruiser should be called 'Tianlong-class cruiser'." ”

Lin Fei smiled: "You're right, but that's the tradition of Western navies, and I don't want to follow their tradition." ”

Yu Xi'er nodded, didn't say much, Lin Fei arranged some more things for the construction of warships, and then announced the dissolution of the meeting, after the meeting ended, Ling Xue came over and said to Lin Fei: "Brother in the city, your Vulcan plan is stuck in a critical step. ”

Lin Fei asked, "What are the key steps?" ”

Ling Xue said: "The steel we smelt cannot withstand the pressure of the shells, and during the test, there were several explosion accidents......

Ling Xue lowered her head as she spoke, her face was full of sadness, and her voice was also crying, Liu Daming said in a loud voice: "Miss Xue'er, I don't blame you, what are you so sad about." ”

Ling Xue sobbed when she heard Liu Daming's words, and said to Lin Fei crying, "Yes...... Sorry ......"

Lin Fei comforted Ling Xue a few words, and then reached out to wipe the tears on her face, Ling Xue stopped her grief, Lin Fei asked: "Can the forging press and lathe that Chen Fu and Yu Xier bought from Taiwan in the previous stage process process the gun barrel?" ”

Ling Xue nodded and said, "Yes, the 120 mm diameter you designed, and the length of 40 times the diameter is just the maximum size that the machining equipment can process, if it is large, it will not be processed." ”

Liu Daming suddenly realized at this time and said: "Lao Lin, it turns out that you set the design index at 120 mm caliber and 40 times the diameter length because of the limitation of machining equipment!" ”

Lin Fei nodded and said, "Yes, the machining equipment does give us a lot of restrictions, and now we don't have too much time to manufacture the machining equipment." ”

Lin Fei answered Liu Daming's question, and then said to Ling Xue: "It's good if it can be processed, I have already thought of a solution to the problem of not being able to withstand the pressure of the firing chamber, now you take me to the artillery processing factory." ”

Ling Xue agreed, took Lin Fei and Liu Daming out of the conference room, and didn't go far to the outside of a factory, outside the factory was paved with railroad tracks, these rails stretched all the way to the steel mill in the distance, these rails were captured by Lin Fei from the mine in Wuduan City, Lin Fei asked people to spread them here, and the steel smelted in the steel mill could be directly sent to the artillery factory for processing.

Ling Xue took Lin Fei to the door of the factory, and before he entered the door, he heard a fierce quarrel inside: "Obviously, the steel made by your steelmaking plant is not good, but we have to blame for the problem in machining, our processing process is in accordance with the requirements of His Majesty, how can it be wrong?" ”

"Our smelting process is also in accordance with the requirements of the majesty, adding nickel, fierce and other ores, the proportion and weight have been measured several times, and the error control is within the scope of the permission stipulated by the majesty, and the steel we make is fine to do anything else!" Why is it so troublesome to use it on your Vulcan plan? ”

"If there is no problem in the smelting and processing links, then the problem must be in the ore!"

"Why are you blaming us for the ore again? The metal from our ore smelts is no problem to make anything else! How did the Vulcan plan go wrong? ”

Lin Fei pushed the door and took a look, only to see Guan Shanyue, the person in charge of the ore part, Liu Siming, the person in charge of the smelter, and Zhou Yuanzhi, the person in charge of the machining department, were gathered together, arguing fiercely.

Lin Fei smiled and said, "Don't make any noise! ”

The three of them stopped arguing and came to Lin Fei together, and just about to speak, Lin Fei waved his hand lightly and said with a smile: "You don't have to argue, the processing of 120 mm caliber guns is much more difficult than 60 mm guns, it is not normal if you don't make mistakes, I thought of a way to solve the problem of exploding." ”

The three of them hurriedly asked, "What method?" ”

Lin Fei clasped his hands, made the shape of a cannon, and then said: "Now my hand is the barrel, when the explosive explodes inside, the barrel will expand to the outside, and when the force of the explosion is very strong, the barrel will not be able to withstand it, and cracks will appear, I believe everyone understands this process." ”

The three of them all nodded, and Lin Fei said, "If we find a way to make the cannon barrel expand in advance before it bears the explosive force, so that the cannon barrel itself will produce a contraction force, and there will be no cracks when it bears the explosive force again." ”

The three of them were surprised for a while, and asked suspiciously, "Can this method work?" ”

Lin Fei thought to himself, this method I am talking about is the "self-tightening tube technology" of my time, how can it not work?
