The strongest rocket soldier

Chapter 928

"It's unbelievable, it's unbelievable. That problem was actually solved by someone. Such a composition, such a design, is so perfect. I don't know who conceived it."

Hearing Ding Xiaojun's somewhat excited words, Li Guimin took two steps, came to his side, and asked Ding Xiaojun with a smile: "How do you see?"

Ding Xiaojun shook his head without looking back: "I didn't see it, this is not 21, nor is it 21 A. If I guessed correctly, this should be a new model missile map of the 20 series, because the old version, 'automatic' The homing' system has always had a power distribution defect, and in this image, that defect is no longer present, so it must be a new model missile."

"You are right or wrong. To be precise, the 21 series will be equipped with new standards. In other words, the picture you see is not a new type of missile, but the original 21 series. You are looking at the new standards of various upgrades." Li Guimin said to Ding Xiaojun who did not look back.

Ding Xiaojun looked at it from top to bottom. Not long after, he finally saw the problem. In fact, he should have seen it a long time ago. The reason why he didn't look at it before is that he found out that he was stationed in the factory. In the meantime, there was a problem that even the factory was puzzled at that time, but this problem has been perfectly solved now, and he was immediately attracted by the solved problem.

"Here you go, this is the upgraded Type 21 A. The biggest difference between Type 21 A and Type 21 is..."

As Ding Xiaojun said, he turned around, but out of the corner of his eye, he noticed the strange gazes from the students in the classroom.It was at this time that he realized that he had unknowingly walked up to the podium.

"Teacher, I'm sorry, I was too excited, and somehow, I came to the front."

Li Guimin smiled at Ding Xiaojun: "It's okay, since you have already come up, then the next class is up to you to explain to everyone, okay?"

"What? Let me talk, no, no, I'm good at it, I'm just a technical soldier, how many catties I have, I still know it very well, I'm talking, even if I can speak, I don't know What should I say, no, really no." Ding Xiaojun said while waving his hands.

"You can't do it. As far as the knowledge you know now, I'm afraid you know a lot more than I do. If you say you can't do it, then I can't do it either." Li Guimin thought in his heart, but he didn't say it out. Switched a projected image, and then said: "As far as this control system block is concerned, in terms of your personal understanding, you have to believe in yourself."

"I……"

Ding Xiaojun was about to explain something, when Li Guimin patted him on the shoulder: "You don't need to explain it according to the knowledge of science and technology, you just need to tell what you know and your own understanding, just tell it out .”

After Li Guimin finished speaking, he turned around and got off the podium. He walked back to Ding Xiaojun's seat, sat down, and gave Ding Xiaojun a look with a smile.

Catch the ducks on the shelves, this is purely to drive the ducks on the shelves, this is not as good as the teacher's class, the teacher lectures, not to mention that they teach this kind of knowledge points all the year round, although there will be new updates, but the general direction remains the same Yes, not to mention, teachers have lessons prepared before classes start.

Ding Xiaojun didn't make any relevant preparations. He was just released temporarily and had to improvise.

This is not as good as dismantling and assembling missiles, so he really doesn't worry about it. He has been doing that kind of work all the time. When he does it, he is still confident, because his technical ability is really not lazy.

This is like giving birth to a child. There is something in the belly, and it will come out naturally. You don’t need to worry about it, but you don’t have anything in your heart, how to give birth.

Although he was very reluctant, it wasn't that the soldiers were talking about technical homework, and even though he was afraid that he might not be able to speak well, he had the intention of shrinking back, but now, Li Guimin has stepped off the podium and sat in his seat. Look, even he plans to listen to Ding Xiaojun's lecture.

"It seems that the veteran hasn't done the relevant ideological work well, so let's cheer him on, come on, let's chirp together." Sitting below, Li Guimin applauded first.

"Papa papa..." All the other students in the classroom applauded. Seeing this, Ding Xiaojun could only take a deep breath, and then looked up at the projected image.

This is the case in the army. As long as you are encouraged by others, you have to fight hard. The most obvious manifestation is the singing of the army. Ding Xiaojun has no way out, so just bite the bullet and go.

"At the teacher's request, then I will talk about it, everyone look at this picture, these..."

"Then let's explain the force now, which is directly related to the control system. I would like to ask, who can tell me what are the forces and moments acting on the missile?"

Ding Xiaojun's speech became smoother and smoother, and he also used the question-style teaching very substitutingly.

But unfortunately, I don't know whether the students are unwilling to cooperate or the students can't answer. In short, no one is willing to raise their hands to answer, but every student is looking at Ding Xiaojun seriously, and I don't know if they just Wait for Ding Xiaojun to give the answer.

Ding Xiaojun paused for half a minute. He wanted to give the students some time to answer, but when he looked over, no one raised their hands.

It's embarrassing, isn't it? When I ask a question, no one is willing to raise their hand to answer. I have to say, it's a very embarrassing thing.

"Well, since no one has come to give you an answer, let me explain to you that the forces acting on the rocket vehicle can be roughly divided into three types, namely, engine thrust, aerodynamic force, and gravity."

After talking about the three forces that belonged to each other, Ding Xiaojun paused for a few seconds to see if he had anything to add or express his personal opinion, but unfortunately, no one had any opinions.

"Okay, then I will continue to talk about it. We are classifying the forces, that is, the controllable forces and uncontrollable forces I want to talk about. Among them, engine thrust and aerodynamic force, these two forces, they It belongs to the controllable force, and the controllable force can be divided into two subcategories: tangential force and normal force.”

"And the third force, that is, the gravity that was not mentioned. Gravity belongs to the uncontrollable force in the original classification."

"The torque acting on the rocket vehicle is divided into control torque and disturbance torque. The control torque is generated by the control mechanism relative to the center of mass of the aircraft. The disturbance torque includes engine thrust eccentricity and various production errors, as well as wind disturbance and control mechanism deflection error.

And this kind of..."
