Chapter 190: Forming an Artillery

Lu Bingyi and Liu Bensheng came to Zhang Zhimu's office with a pile of drawings. Liu Bensheng put the drawings on Zhang Zhimu's desk, and Lu Bingyi said: "Mr. Zhang, take a look, this is the drawing of the school that came out after more than 20 days and nights." ”

Zhang Zhimu spread out the drawings and said, "I didn't expect it to be drawn so quickly, you must be tired." Oh, let me tell you, it's not good to look like this, the construction of our kiln has just started, and the days will be long. ”

Liu Bensheng knew that Zhang Zhimu really cared about them, and said: "I'm not afraid of being tired, that is, we are going to work on so many projects at once, and we are afraid that cement will not be able to keep up, and now we can't do without cement." Now that the stone has been solved, Li Yunhe's stone sawing machine can top hundreds of people at once. The sawn stone is smooth and neat, and it is simply so easy to use. If we don't have enough of it, we can make a lot of money by selling stones. ”

This time to build the school, Zhang Zhimu chose the location of the school a little farther away from the southwest direction of Yaogang, on the south bank of the section of the river after the turn of the Xiaoling River. I chose this place because it can occupy a little more space and leave room for future development. Zhang Zhimu's psychology has a long-term blueprint for Yaogang University. It's very quiet here, and the river rises after the dam at Lingshui Wharf fills the water, and the environment will be beautiful. If there is not enough space on the south bank, build a bridge, and the north bank is also a space for development.

The main teaching building of the school is designed to be five floors in the south. According to Zhang Zhimu's requirements, the classrooms are all very high and have large windows. When building, it is necessary to keep the embedded pipe for the wire. As for the water supply, it is even more necessary. The east and west sides are the laboratory building and the student dormitory. In the middle is a large playground with a row of more than a dozen basketball and volleyball courts; In the middle is a large football field, and next to it are two halves of small football fields; There are also many facilities such as horizontal bars and parallel bars. Between the north side of the teaching building and the Xiaoling River, there is an indoor gymnasium, the main thing in which there is a swimming pool with a length of 45 meters and a width of 25 meters. On the east and west sides of the gymnasium is a cafeteria and a bathhouse for students. The school is to be fenced off with a wooden fence and painted with green paint. The roads on the campus should be paved with stone slabs and bricks, the exposed soil should be greened with trees, tall trees should be planted around the campus, and small trees should be planted on both sides of the paths on the campus. Flower beds, ponds, and pavilions for reading should also be built at the same time.

Such a request, when Zhang Zhimu put it forward, Lu Bingyi and Liu Bensheng both gasped, and Liu Bensheng asked: "Mr. Zhang, are you going to build a garden?" ”

Zhang Zhimu said: "Yes, I want to build a garden-style school, and in the future, all the students of the Ming Dynasty will be proud to be admitted here." This is the beginning, and my idea is that it will be expanded several times over. I want to invite all the Ming Dynasty, skilled craftsmen, literati and artists, and strange people to teach students. ”

Lu Bingyi and Liu Bensheng combined Zhang Zhimu's ideas and combined their ideas with great enthusiasm to design. They know that this is a great thing that will be done for generations to come.

After listening to Liu Bensheng's introduction in combination with the drawings, Zhang Zhimu said: "You guys are much more careful than I thought, very good." You don't have to worry about cement, there are two bigger cement kilns under construction. I've told them to expand two more. Men are asked for silver, and silver is given to them. It's just that the transportation is too problematic, the coal needed there has to be brought in, and the burned cement lime has to be shipped out. The smelter and the mines are facing such a problem. ”

Lu Bingyi has also been concerned about this issue and said: "There is no other way now but to increase animal manpower." ”

Zhang Zhimu said: "If the big blast furnace that Li Dong gave them is ignited for production, if they succeed, we will build a few more such blast furnaces, and when the steel production comes up, we will build a railway and transport the coal from Niutoushan first." ”

Lu Bingyi said: "I have been waiting for President Zhang to lead us to build a railway, and we all want to see how the steam train travels on the railway. ”

Zhang Zhimu said: "Don't worry, when we are busy during this time, I will tell you about the knowledge of railways." Now with our technical level, there are no obstacles to the construction of the railway. It's just that the demand for steel is too great for the construction of railways. ”

After talking about the design of the school, Zhang Zhimu said to Lu Bingyi: "Mr. Lu, you also take your disciples to participate in a somewhat complicated work to figure out the methods that need to be calculated for the command of mortars. ”

Zhang Zhimu's knowledge of mortars is also limited, he only knows that artillery shooting is generally divided into two types: direct-aim shooting and shooting according to the shooting elements. Straight shooting is easy to understand; The Zhuyuan of Zhuyuan shooting is the necessary technical parameters for the artillery to hit the target, such as the indicator ruler, height and direction, and the Zhuyuan shooting is based on these parameters. The angle used in the azimuth parameter is represented by the dense position, and the dense position has two calculation methods, one is to divide the 360 degrees of each week into 6000 dense positions, and the other is to divide the 6400 dense positions, which is convenient to calculate with 6000 dense positions, and it is convenient to process when using 6400 dense positions to process the index dial, because 64 is the 6th power of 2, and 6400 is 100 after 6 equal divisions. Of course, 100 can be divided into two more equal parts to get 25. In order to facilitate processing, Zhang Zhimu also adopted the method of 6400 dense positions per week.

However, Zhang Zhimu still brought Sun Liang, who was engaged in telescopes, to the mortar firing site first.

There are already five mortars test-fired, and the firing distance under the same firing parameters each time is taken as the average of the five guns. Seeing Li Yunhe, who had been at the test site, Zhang Zhimu called Sun Liang and him together and said: "Yunhe From now on, you will hand over the matter of shooting the watch to Li Wei and them, and they will continue to complete it." When Li Wei finished firing the meter, he formed an artillery unit. I will give you two tasks today, the first is that you have to cooperate with Sun Liang to develop a mortar sight, this sight requires a horizontal tube, and there must be a cross line on the mirror surface, and in order to facilitate aiming, the eyepiece and the objective lens can not be coaxial, and now you can't make a prism, just use two glass mirrors as reflectors, and when the prism can grind it out, replace it with a prism, and the scope is about three times. ”

As he spoke, Zhang Zhimu took out a sketch and said: "The second is that Li Yunhe wants to organize people to install buffer machines for mortars, because there is recoil after the shells are fired, and this recoil has an impact on the gun mount, and before the shells are fired, the vibration of the gun mount will affect the shooting accuracy." The buffer machine is a buffer tube, which is equipped with two springs and a buffer rod, one large and one small. When the shell is fired, the gun carriage remains immobile due to inertia, and the gun body drives the buffer rod to recoil through the buffer ring, and compresses the spring, on the one hand, to ensure that the firing angle of the gun body remains unchanged before the shell is out of the muzzle, and on the other hand, to alleviate the impact of recoil on the gun mount. ”

Li Yunhe's brain was a little amazed by Zhang Zhimu's cleverness, and he quickly understood the usefulness of the buffer machine that Zhang Zhimu said, which was also related to the experience he gained after a few days of test firing, but he quickly pointed to the buffer machine on the drawing and asked: "What is the small spring on the upper part of the buffer machine used for?" ”

Zhang Zhimu was very happy to see that Li Yunhe quickly understood most of the principles of the buffer machine, and explained: "When the gun body is recoil upward due to the recoil force of the soil, the gun body drives the buffer rod to move upward, and the small spring between the head of the buffer machine rod and the ear seat is compressed, which alleviates the direct impact of the recoil force of the soil on the gun mount. ”

Li Yunhe nodded.

After Zhang Zhimu answered some questions for Sun Liang and Li Yunhe, Zhang Zhimu said: "What I can tell you is an idea, and you have to solve specific things." If you ask me again, I don't know. ”

Li Yunhe said: "The more I tried, the more I felt that there were many things to improve, and I made up my mind to change them all this time." ”

Zhang Zhimu saw that Li Yunhe still wanted to improve it all at once, and said: "You must not move this mortar that has already been formed, I think Li Wei and they have already made it up and can use it, and the next model will be slowly changed in the future." Otherwise, you will have to redo all these shooting meters, which will take a lot of shells to try. ”

Li Yunhe scratched his head and said, "That's right, it's much stronger than their bow thunder and crossbow thunder." I think some of them can hit their target with just two shots. This thing is also used by anyone. ”

Zhang Zhimu said: "Sharpshooters and sharpshooters are sometimes really natural. Li Wei: This time, their mortars are enough, right? ”

Li Yunhe knew that Zhang Zhimu was not at the shooting range during this time, and he said with a smile: "Mr. Zhang, you don't know, Li Wei and they don't have enough." He brought more than 100 of his people over, and each person in the queue could only shoot a few shots, and he could only try his hand, but he didn't think it was enough. I have already arranged for the workshop to produce mortars. I'd like to produce 20 for them to practice with. ”

Zhang Zhimu said: "Don't be too stingy, you will produce 200 guns in this batch at once, and the warhead charge of the practice bullet can be black**, and the future live ammunition will be smokeless**." The saltpeter they wanted has arrived, and with saltpeter, there will be nitric acid. In this case, smoke-free ** will be available in large quantities, so you can do it with confidence. ”

Li Yunhe was startled when he heard Zhang Zhimu say that he would produce 200 mortars at once, and said: "One cannon costs five people, and Li Wei and the others don't have a few people in total, do they use so many cannons?" ”

Zhang Zhimu and Li Yunheping were very familiar, and punched him and said, "You stupid, won't Li Wei's men and horses expand?" Some cannons can also be prepared. ”

"You're going to expand the artillery?" Li Yunhe understood a little.

Zhang Zhimu said: "Think about it, if something happens to the kiln gang, if we put up a hundred mortars on the post, as long as the shells are sufficient, can anyone get close?" ”

Li Yunhe said: "With 50 cannons, no one will be able to get close to the kiln gang. Even at night, we light up our searchlights and shoot the same. ”

"Let's not talk about the night, now you are shooting directly, have you ever thought about hitting the target with a mortar across the mountain?" Zhang Zhimu asked.

Li Yunhe really didn't think about this problem, and said: "I haven't thought about it, but the mortar shell is a parabola, which should be okay, but it can't be aimed." ”

Zhang Zhimu said: "I will invite Lu Bingyi to come and develop a set of methods to attack targets across the mountain." I'll tell you a way. You first arrange an artillery commander on the top of the mountain, he uses two bamboo poles to separate a distance, aim at the target, you adjust the mortar and his two bamboo poles parallel, and then he is giving you the distance, you convert it to the scale of the high and low machine, so that you can launch an attack. ”

Li Yunhe patted his head and said, "That's right, let's aim the mortar at the first pole first, lock the aiming barrel, and adjust the sight to aim at the second pole; After locking, aim at the first lever with the steering machine. So that the mortar is parallel to the two poles. Shoot in the direction of Zhuyuanli and aim at it. ”

Zhang Zhimu said: "The problem is how to calculate the distance between the artillery commander and the target by the distance between the artillery commander on the mountain and the distance between the target and the angle between the three points.

At this time, Li Yunhe knew that if the artillery was used well, the power would be too great, but there was too much knowledge here.

In fact, Zhang Zhimu knows the complexity of artillery better than Li Yunhe, and now these are just the simplest things. Therefore, Zhang Zhimu has decided in his heart that the two-year military class recruited will be specially set aside for the artillery class, which is the most complicated branch of the military now. I also have to discuss with Fan Chengkun to set up two sailor classes, half of whom are directly selected in his team, and half of whom are recruited according to their grades.

Zhang Zhimu was studying mortars with Li Yunhe, Sun Liang and others at the mortar shooting range with great interest, when suddenly a fast horse ran over in the distance, and Zhang Zhimu seemed to be a guard in front of his office, which made Zhang Zhimu feel a little strange. The person jumped off the horse, reined in the war horse and said to Zhang Zhimu: "Mr. Zhang, go back quickly, Miss Yang said that something happened, let you go back quickly." ”
