The strongest rocket soldier

Chapter 927 Lesson [-]

"Today, let's learn about the circuit of the secondary engine." Right in front of the podium, Li Guimin used a computer projection to present a three-dimensional image of the circuit.

When Ding Xiaojun saw it, he always felt very familiar with this circuit, but the structural drawings he had seen before were all flat, and this three-dimensional one was really the first time he saw it.

Ding Xiaojun had to sigh, the current technology is still strong, learning related skills and knowledge does not need to be written by hand like in the past, the projection technology is indeed more intuitive, he couldn't help thinking, if the projection technology is brought to the army, it will be Isn't it more intuitive to lead troops?

Through the projection, he also thought of teaching in a resourceful way. If it is said that the process of action is recorded as a video with the method of explanation, so that leading troops, especially technical soldiers, is much better than memorizing the process.

Humans must always look forward. The development of science and technology will eventually allow machines to replace humans. Perhaps, in the next few decades, the technical operations of missiles will only need people to sit in front of computers and use computers to control robots to complete.

This is just an assumption. Perhaps, the development of missiles in the future will reach a point where human maintenance is no longer needed. It is even possible to miniaturize missiles, continent-level missiles, and develop to cruise missiles, or even smaller.

"Ding Xiaojun!" Li Guimin saw that Ding Xiaojun's thoughts had strayed from the topic, so he called out by name.

Ding Xiaojun was a little distracted. He didn't realize that Li Guimin had called him by name. This was also different from him in the past. In the past, he seldom lost his mind during work and study.

Li Yue'e bumped Ding Xiaojun lightly with her arm, lowered her head and said softly, "The teacher is calling you."

After reacting, Ding Xiaojun quickly stood up, he regretted a little, what happened to him, such an important course, as a transfer student, he just took the first class, and he was distracted, as a veteran, he made such a mistake The mistake, it should not be.

Li Guimin didn't mean to blame Ding Xiaojun. He pointed to the projected structure diagram and asked Ding Xiaojun, "Can you see clearly, is this part of the circuit structure of the secondary engine?"

Regarding the questions Li Guimin asked, among the technical soldiers in the army, if you ask anyone, you may get an answer you don’t know, but Ding Xiaojun is that exception. The blueprints have been studied thoroughly. Although the two-dimensional drawings are very different from the three-dimensional drawings, at least you can see the familiar points in each part and the two-dimensional drawings. At least Ding Xiaojun still knows the questions Li Guimin asked.

"Report, Comrade Teacher, the part you pointed out belongs to the closed-loop system of the secondary engine." Ding Xiaojun said confidently, this is not because he is showing off his knowledge.

Before Li Guimin confirmed it, Ding Xiaojun said again: "The closed-loop system is a part of the missile flight control system. Its frequency characteristics include bandwidth, resonance peak value, and resonance frequency." The frequency characteristics include bandwidth, resonance peak value, and resonance frequency. Wait, it is a quality standard of the missile flight control system. It cooperates with the open-loop system to jointly complete the stability and transition process in the flight control. Since there are open-loop cut-off frequency, amplitude margin, and phase angle margin, by the way, the open-loop system circuit is the above triangular area. "

After Ding Xiaojun finished speaking, all the students in the classroom were dumbfounded. They turned their heads and looked at Ding Xiaojun. Let alone whether what he said was right or not, just what he said was enough to fool people.

As a technical soldier of the army, of course he can't learn all of this knowledge. Even Li Guimin on the podium in front of him looked at Ding Xiaojun in disbelief. As for the knowledge that Ding Xiaojun gave briefly, even he was just I've seen it, but he doesn't belong to the army technician profession, so he didn't take note of it.

"Ding Xiaojun, you said that the academy wouldn't be able to learn his knowledge. I'm curious now. As a technical soldier in your army, you can't meet the interviewees. How do you know such comprehensive knowledge. " Li Guimin asked.

"The report teaches that, indeed, it is very difficult to acquire this knowledge if you are only in the army. As you said just now, even the academy will not teach this knowledge. The reason why I know this is because I have been stationed for a while. The experience of the factory is that I learned this knowledge in the research institute stationed in the factory." Ding Xiaojun replied.

Li Guimin was stunned for a moment, he couldn't help thinking, you have already been stationed in the factory, and you have learned enough knowledge, why come to the academy to study.

That's what he thought, but he didn't ask, he looked at Ding Xiaojun again, an idea appeared in his mind, he raised his finger to the projected image, and asked Ding Xiaojun, "Do you know this structural diagram? "

"I'm not sure, because all I've seen before are flat drawings. As for this projected image, it's the first time I've seen it, but I'm sure it's from the df21 series. As for whether it's df21 or 21A, I'm I can’t be sure, because the picture is not complete.” Ding Xiaojun can’t say too much, he has always been rigorous in terms of technical expertise.

Li Guimin tapped on the computer, and then the projected image changed. He looked at Ding Xiaojun again and asked, "So what now?"

Ding Xiaojun turned his eyes to the newly projected image, his gaze was straightened, the projected image attracted him, he didn't notice, at this moment, he couldn't help walking towards the projection.

Li Guimin saw Ding Xiaojun walking towards the podium, smiled, and made way for Ding Xiaojun, allowing Ding Xiaojun to walk to the side of the projected image.

Ding Xiaojun in front of the projected image seemed to have been cast a spell on him. He stood there with his head slightly raised, his eyes always lingering on the projected image.

At this time there were whispers in the classroom, Li Guimin turned his head, he made a booing gesture to the students in the classroom, then turned his head again, squinting slightly at Ding Xiaojun who was staring at the projected image on the podium.

Ding Xiaojun was fascinated by watching, Li Guimin didn't bother him, and just let Ding Xiaojun watch like this, the time passed minute by minute, Li Guimin looked at the situation, I am afraid that Ding Xiaojun will look at it for a long time, and he turned around again, yes The students in the classroom said: "Don't be idle, review the knowledge you have learned before."

Another ten minutes passed, and Ding Xiaojun, who was looking at the projected portrait, suddenly said, "It's unbelievable, it's unbelievable, that problem has been solved by someone, such a composition, such a design, it's so perfect, I don't know who came up with this."
