The sound of clanging iron, the sound of the steam engine working, and the sound of everyone talking, it was a lively scene. Pen ~ fun ~ pavilion www.biquge.info

Zhao Zuolin introduced: "Lord General Soldier, you see, some parts of machine tools and equipment have begun to be built, and some parts of our big steam engine have also begun to be manufactured. ”

This so-called large steam engine is designed by Zhang Feng and will be used in the future for ironclad ships, at present, it belongs to the largest steam engine, and the power of a single steam engine can reach more than 2,000 horsepower, which is completely different from the steam engine with hundreds of horsepower that everyone has made before.

The steam engine is larger, more complex, and more demanding, fortunately, this steam engine Zhang Feng designed it himself, fully considering the current process and manufacturing level, Zhao Zuolin and they spent a little time, and they should be able to manufacture it.

With this big guy, the ironclad ship will have qualified steam engine power, and it will be possible to sail to the ocean in the future.

Zhang Feng attaches more importance to this steam engine, and after seeing the manufacture of some parts, Zhang Feng is more satisfied.

After reading several production and manufacturing workshops, Zhang Feng took everyone back to the office building, which is a three-story office building, with cement steel bars, and the ground is no longer wooden, but cement.

Conference room on the third floor.

Everyone beckoned everyone to sit down, and then, Zhang Feng took out the drawings he brought, handed them to Zhao Zuolin and said, "Everyone take a look." ”

Seeing Zhang Feng take out these drawings, everyone became curious, and they wanted to guess what drawings the chief soldier brought over this time, whether it was the design drawings of a certain new machine tool or the design drawings of a new steam engine.

We are either the backbone of management or technology, and we couldn't read the drawings before, but now, we can fully understand the drawings drawn by Zhang Feng.

Of course, when Zhang Feng usually has free time, he will also give a class to everyone, talk about drawing, design and technology.

Next door to this conference room, there is a large classroom, which is built according to Zhang Feng's requirements, which can accommodate more than 100 people to listen to the class.

Every time I come to the class, there are not only technical backbones, management backbones, but also some craftsmen, and everyone comes into contact with things, from Arabic numerals, millimeters, to tolerances, to measurements, to drawings, to craftsmanship and so on.

"It's a kind of artillery!"

When you see the design drawings, you can immediately see that this is a kind of artillery, and it is absolutely different from ordinary artillery.

Zhang Feng naturally knew the importance and status of artillery in modern warfare, and Zhang Feng had long wanted to manufacture artillery, but due to the limited conditions, he was never able to start.

Now the conditions have been basically met, the Shanghai Iron and Steel Plant can smelt the best quality steel of this era, the Shanghai Machinery Manufacturing Bureau has also started, and there are some machine tools.

Zhang Feng personally designed this artillery, of course, from a modern point of view, this artillery is a little backward, but hundreds of years ago, it was undoubtedly very advanced.

Compared with the current redcoat cannon, Furlong machine gun, etc., this artillery is much more advanced.

The barrel is also cast by the casting process, but it is cast first, and then machined, especially the rifling is also processed in the barrel, and the steel smelted by the Shanghai Iron and Steel Plant is used to cast the gun, which has more than one level of quality.

It is also a front-loading gun, and black powder is still used, but this gun has many other obvious differences, such as the design of the crank, there are gears, and the firing angle can be adjusted, and the firing angle is about minus five to fifty degrees.

Not only can the shooting angle be adjusted by the crank, but the horizontal direction can also be adjusted, about 45 degrees from left to right, so that the shooting range is wider.

In addition, this gun had two wheels, which could be dragged by horses on the march, and the maneuverability was greatly enhanced.

The only regret is that the caliber of this gun is a little small, the caliber is 70 mm, Zhang Feng considered the first production of artillery, Zhang Feng designed the caliber of the gun to be 70 mm, using 22 times the diameter, that is, the total length of the barrel is about 1.5 meters.

The so-called double diameter of the gun is the ratio of the length of the barrel to the diameter of the barrel, the larger the double diameter, the longer the barrel, the longer the acceleration time of the shell in the barrel, the higher the exit velocity of the shell, and the farther the shell will hit.

Modern artillery, the double diameter has forty-four, fifty-two, fifty-five, etc., and even seventy and one hundred times the diameter, the double diameter is high, the corresponding gun chamber pressure is also high, and there are high requirements for the barrel material and processing technology.

Twenty-two times the diameter is not low, and some cannons in the Ming Dynasty are several times the diameter, or more than ten times the diameter, because of the limitations of the casting materials and processes.

The artillery designed by Zhang Feng is a towed gun, which is composed of a gun body and a gun carriage, which can adjust the angle of shelling, and can be fired horizontally, curvedly, and can be pulled by horses.

After Zhang Feng introduced the design of this artillery, even if everyone was not a soldier, everyone was stunned, undoubtedly, the design of this artillery is very advanced, and the performance may be very good.

"Lord Commander, you designed it! This cannon is so awesome! ”

"It's not just bull spirit, such a cannon is simply unheard of, and I have only seen it in my life!"

“……”

Everyone, you say a word, I say a word, your face is full of shock, if you are not used to seeing Zhang Feng's magic, everyone will definitely be even more surprised.

Zhang Feng smiled slightly, "Lao Zhao, these drawings will be handed over to you, you digest them carefully, and ask me if you don't understand, and we will strive to make one or two sample guns first." ”

The manufacture of sample guns is naturally for experiments, such as shelling tests, and by the way, it also accumulates manufacturing experience to lay the foundation for mass production and manufacturing in the future.

Zhao Zuolin said: "Lord Commander, we will collect these drawings, and we will strive to manufacture the sample cannon as soon as possible." ”

Zhang Feng nodded, Zhang Feng believed that Zhao Zuolin and others would definitely be able to manufacture the sample cannon if they had this level, because Zhang Feng fully took into account everyone's level and existing conditions when designing, otherwise, according to Zhang Feng's technical level, he would definitely be able to design more advanced artillery, such as rear-loading guns.

Zhang Feng stayed in Shanghai County for three days, and only returned to Songjiang Mansion after three days, during which Zhang Feng went to the steel factory, went to the shipyard, and also saw the construction of the industrial park.

Three days later, the General Army's Palace.

The first thing Zhang Feng did when he came back was to make an appointment with Tan Yixian, the prefect of Songjiang, if it was before, when Zhang Feng was still the chief soldier of the regiment, Zhang Feng had to go to the Songjiang Mansion to meet Tan Yixian, and when he visited, it would depend on whether Tan Yixian had time, but now it is different.

Zhang Feng is the chief soldier of Songjiang, and he is the third grade, and Tan Yixian only has the fourth grade, although he is noble and cheap, but Zhang Feng holds the handle of the army, and the status of the two has been reversed.

Now Zhang Feng wants to see Tan Yixian, Zhang Feng only needs to talk to the guard, and the guard will go to Songjiang Mansion to inform him, Tan Yixian is busy, and he must put down what he is doing and rush over immediately.

That's it this time, Tan Yixian soon came to the General Soldier's Mansion, got off the sedan chair in front of the gate of the General Soldier's Mansion, and then hurriedly walked inside, and when he walked to the front hall of the General Soldier's Mansion, he was already a little out of breath and a little sweaty on his forehead.

"Xiaguan Songjiang Governor Tan Yi has seen the chief soldier first."

Seeing Zhang Feng, Tan Yixian saluted politely, now Zhang Feng's identity and status are no longer the same, Tan Yixian must correct his mentality and pretend to be a lower official.

Zhang Feng smiled and said, "Lord Tan, it's polite, come, please take a seat." ”

Zhang Feng beckoned Tan Yi to sit down first, the orderly brought hot tea, and Zhang Feng said, "Lord Tan, how are you doing?" OK? ”

Tan Yixian hurriedly said: "Back to the general soldier, everything is fine, the people of Songjiang Mansion now live and work in peace and contentment, and I, the prefect, are also happy to have a relaxed life." ”

Zhang Feng nodded, this is the truth, as many people have jobs, everyone is really getting rich, Zhang Feng's factories, not only drove the local economy, by the way, the entire Songjiang Prefecture area security has been invisibly improved.

Zhang Feng said: "Master Tan, I called you over this time, I have a big thing to hand over to you to do, and in the next period of time, you will not be so idle." ”

Tan Yixian said: "Lord Commander, you can give orders. ”

Zhang Feng nodded, this Tan Yi first put his position more correctly, and his current tone is basically a subordinate.
