The "self-tightening tube" technology is one of the advanced artillery manufacturing technologies in Lin Fei's era, this technology has greatly improved the pressure-bearing capacity of the artillery barrel, and the equipment required by this technology is relatively simple, and it also appeared in this era in 1895, but it has not been known by too many people.

When Lin Fei was trained in the special forces base, he had learned the use of artillery, and he also had a certain understanding of the manufacture of artillery, so he knew this technology, the advanced body tube manufacturing technology of artillery, as well as the wire winding body tube and multi-layer body tube, which Yanhuangcheng could not do, but Lin Fei was preparing the relevant process to be used in the future when manufacturing 300 mm, 400 mm or even 500 mm caliber cannons.

Lin Fei did not explain the principle more, but told the craftsmen about the process of self-tightening body tube, and Lin Fei asked the craftsmen to pass the high-pressure liquid into the body tube blank to be processed, and the high-pressure liquid can be used to use water, and then use the high-pressure steam generated by the steam engine to push it, and the high-pressure liquid can be formed.

Lin Fei told the craftsmen the method of "hydraulic self-tightening body pipe", and the craftsmen immediately went to prepare the relevant equipment, and Lin Fei told the craftsmen to do the preparation work first, and then process the body pipe.

Lin Fei solved the problem of body management, and said to Ling Xue again: "Take me to see the system retreat and return machine." ”

Ling Xue nodded, and took Lin Fei and Liu Daming to another factory, and on the way Liu Daming teased Ling Xue: "Little girl, do you know what a reinstatement machine is?" ”

Ling Xue was only a little over sixteen years old, but she didn't think she was young, and when she heard Liu Daming call herself a "little girl", her eyebrows were raised, and she said angrily: "Why don't you know? The city lord's brother has already told me that it is something that counteracts the recoil of the artillery, and with this thing, the cannon can fire faster! ”

Ling Xue was not wrong, one of the main reasons for the slow rate of fire of the initial artillery was that it could not counteract the recoil, and the recoil force caused the aiming line of the artillery to change after firing, and if you wanted to fire again, you had to aim, so it was difficult to get up fast.

Liu Daming laughed and said, "The little girl seems to know something!" ”

Ling Xue said dissatisfiedly, "Big guy! Don't think you know how to make a retreat machine, you must not have seen this type of retreat and retreat machine made by the city lord's brother! ”

Liu Daming said disdainfully: "I haven't seen it? Joke! ”

The corners of Ling Xue's mouth rose, revealing a proud smile, and said, "I dare to guarantee, you must not have seen this system and retreat machine, because the city lord's brother said that this kind of system and retreat machine is the most advanced in the world, and even the British don't have it!" ”

Liu Daming was also stunned, stared at Lin Fei with wide eyes, and said, "The world's most advanced system and retreat machine? Do you dare to blow this kind of cowhide? Tell me where it's advanced? ”

Lin Fei smiled and didn't answer, and said, "It's hard to say now, I'll tell you when I see our system and retreat." ”

While they were talking, the three of them walked to the outside of a factory, and there was a "buzzing" sound from time to time, Ling Xue pushed open the door of the factory and walked in, only to see several machine tools running in the factory, these machine tools were bought by Yu Xier and Chen Fu from foreign businessmen, and they were still using steam engines as power.

Several craftsmen are operating the turning tool to cut the blank, and the coiled metal scraps are splashing out of the blank and falling into the scrap recycling box under the lathe, and several shaft parts of different lengths are placed on the platform on one side, and there is a heat treatment furnace in the distance of the platform, and several craftsmen are busy by the fireside.

Liu Daming looked around the factory and smiled at Ling Xue: "Where is the world's No. 1 rearing machine you said?" ”

Ling Xue pointed to the north with her hand and said, "The warehouse where the finished products are put is over there, so I'll take you there." As she spoke, Ling Xue took Lin Fei and Liu Daming to the north, passed through the busy craftsmen and equipment, pushed open the door of the warehouse, and saw five thick metal cylinders on the wooden platform, Ling Xue pointed to those metal cylinders with her finger and said, "That's them." ”

Liu Daming walked to the front of the metal cylinders, looked at them carefully, turned his head and asked Lin Fei: "This is the reinforcing and reversing machine?" How come there are no springs? ”

Lin Fei said with a smile: "Other countries in the world have springs in their retractors, but our retractors do not have springs!" ”

Liu Daming asked in surprise: "How can you offset the recoil without springs?" ”

Lin Fei said: "I made a liquid from the oil fractionated from the petroleum, which I called 'the repulsion', and added this liquid to the recoiling machine and sealed it with a soft metal gasket. When the body tube recoils, the hydraulic pressure of the recoiling liquid will prevent its recoil, and after the recoil is completed, the hydraulic pressure can complete the recoiling of the body tube. ”

"After using this hydraulic retractor, our rate of fire will be greatly increased, the rate of fire of the rapid-fire guns used by the Japanese is about 6 to 7 rounds a minute, and our retractor can reach at least 10 rounds, and if the operation is skillful, it is possible to reach about 12 rounds!"

Liu Daming's eyes widened in surprise and sighed: "12 rounds per minute? Isn't that twice as much firepower as the Japanese? ”

Lin Fei smiled and nodded, and said, "This is our advantage!" ”

Lin Fei designed this "hydraulic retractor" is actually the modern artillery used in the retractor, this retractor first appeared in 1897, the French Army in its own 1897 type 75 mm howitzer first applied, the result of the 1897 type 75 mm howitzer fired a rate of fire of 18 rounds per minute, so that the British, German guns with a rate of fire of less than 10 rounds per minute are all in the museum.

Liu Daming admired again and again, but it was not too long to frown again, and said: "We only build two slipways now, that is to say, we can only build two warships at a time, I see that the war between the Qing court and the Japanese will end in three months, if according to what you said, the Japanese will attack Taiwan at the end of the war, then we only have three months to build warships, how many warships can we build in three months?" The number of Japanese warships is about a dozen! We have too few warships and we are no match for them. ”

Lin Fei said: "In three months, we can almost build two warships......

"Build two warships in three months? That's too fast, right? Liu Daming exclaimed again.

Lin Fei said with a smile: "In the previous battle, we got a large number of craftsmen, and in these three months, these craftsmen will work overtime and do their best to catch up with the work, and I also used the 'group technology', which can greatly speed up the speed of building ships!" ”

Liu Daming asked, "'Group technology'? What is that? ”

Lin Fei said: "In the past, shipbuilding factories were divided into various large parts to build, the bow, stern, bottom, etc., such classification efficiency is very low, because many parts of the bow, stern and bottom of the ship are very similar, I will give you an example, you will understand as soon as you say it." ”

"For example, a rib plate, the bow of the ship, the stern, the bottom of the ship, according to the original ship-building factory construction method, need to set up a rib production line in the three construction workshops, which will cause a waste of resources, but also slow down the man-hours, after the use of grouping technology, parts with similar shapes and processes are put into the same production line for manufacturing, so that the manufacturing speed is greatly improved."

Liu Daming was stunned again, and sighed: "What a clever way!" I often hear the old fish talk about the British shipbuilding factory, but the British shipbuilding factory doesn't seem to have come up with such a solution! ”

Lin Fei smiled and said nothing, thinking to himself that the technology in a group was the technology that the shipbuilding factory of my era had only found after hundreds of years of exploration, how could people in this era think lightly?

The excitement on Liu Daming's face only lasted for a short while, and his face quickly became gloomy again, and he said worriedly: "Even if we can build two warships in three months, there are only two after all!" The Japanese have more than a dozen warships, can two battleships win a dozen or so battleships? ”

Lin Fei laughed and said, "This is going to use another big plan I just said at the meeting!" ”

After Lin Fei finished speaking, he turned his head to look at Ling Xue and asked, "How is the implementation of the 'Blue Bird Plan'?" ”

Ling Xue said: "The execution has begun. ”

Liu Daming was already stunned by the same advanced technology that Lin Fei had brought out, and he didn't ask much about the "Blue Bird Plan" at this time, Lin Fei smiled at Ling Xue and said, "Since it has already been implemented, then take me to see it." ”

On the way, Ling Xue smiled at Liu Daming and said, "Big man, do you know what a blue bird is?" ”

Liu Daming didn't know the meaning of "blue bird", but he didn't want to say in front of Ling Xue that he didn't know, so he didn't know how to pretend to understand, and said with a smile: "Isn't the blue bird just a bird?" ”

Ling Xue sneered, "If it's just an ordinary bird, why would Brother City Lord use it as the name of the plan?" ”

Liu Daming's face was embarrassed, obviously he was asked by Ling Xue, Ling Xue's face suddenly showed a smug look, Liu Daming suddenly laughed, this laughter stunned Lin Fei and Ling Xue, Ling Xue asked, "Big man, what are you laughing at?" ”

Liu Daming stared at Ling Xue, didn't speak, looked at Ling Xue all over, and asked angrily, "What are you staring at me?" ”

Liu Daming smiled evilly and said: "Sharp teeth, not dignified and virtuous at all, how can you be a mother in the world in the future?" ”

One sentence made Ling Xue's face flush, she was shy and happy, she sneered "hate", and hid beside Lin Fei without speaking, Liu Daming asked Lin Fei at this time: "Old Lin, what is the blue bird?" ”

Lin Fei said with a smile: "In myths and legends, there is a Queen Mother of the West, and the blue bird is the messenger of the Queen Mother of the West, specially delivering news to the Queen Mother of the West. ”

Liu Daming then asked, "What about the Blue Bird Project?" What is it? ”

Lin Fei said: "The blue bird is the bird that transmits the news, what do you say is the blue bird plan?" ”
