country made

The bus stopped directly on the shooting range, and Ji Zhuan, who was wearing a training uniform, got off the bus and was immediately reprimanded by the military instructor like chicks, telling them to stand in line.The teacher in charge of this class is a middle-aged engineer in his 40s. His surname is Zhu.

"Today's class, I guarantee that everyone will like it." He pointed to the shooting range next to him: "Guess what class we are going to have today?"

"gun!"

Everyone shouted.

There is probably no man who is not interested in guns, and the usually quiet students all showed excited smiles.

"Yes, in the next hour, I will ask the army commander to teach you how to recognize and shoot a gun."

The army commander took out several types of firearms to explain to everyone, and disassembled and assembled them on the spot. The neat and handsome movements made the students burst into surprise.Then a gun was placed in front of everyone for them to disassemble and assemble.

Ji Yu is no stranger to guns. He is sometimes seconded to other research institutes to help out. He is also responsible for the birth of certain new types of firearms!Of course, he is responsible for the part of manufacturing precision instruments, the design has nothing to do with him, he is a pure technician.

However, because he touched a lot of guns during that time, he knew the structure and principle of the gun very well. Even though he was not familiar with this gun in his hand, after reading the officer's explanation, he still quickly disassembled it.

"Wow--!"

Suddenly there was a few noises nearby, Ji Yu turned his head, and saw Song Jining assembled the gun and started the safety test.

Sensing Ji Yu's gaze, Song Jining turned his head to meet him, showing his white teeth.

Song Jining, who was born as an alternate captain of the Little Red Soldier, is naturally good at playing with guns.

"Song Jining, perform again!"

It seemed that his action of assembling the firearm was so handsome that the students forgot the barriers and clustered around him and shouted.

"can."

I saw Song Jining's hand on the gun body a few times, clicked a few times, the gun body disintegrated instantly, and the speed was not slower than the officer who just explained.Then he quickly assembled it back, like building blocks, and installed the gun in one go.

The officer on the side asked appreciatively: "Hey, this classmate has played with guns?"

Song Jining grinned: "I have trained before."

"Can you shoot a target?"

"of course."

"Okay, let's demonstrate to the students."

Although many years have passed since the Little Red Soldier period, Song Jining is still very good at playing with guns. Even the army commander praised him and asked him if he was interested in joining the army.

With Song Jining as a demonstration, other students quickly assembled the gun and started shooting.

Although Ji Zhuan has participated in the making of guns, he has never fired a gun himself, and he doesn't like to play with it.Song Jining walked up to him at some point and asked, "Yuanyuan, can you shoot?"

"Yes...it should be..." It's not difficult to see.

Song Jining chuckled: "Okay, I'll teach you."

He held Ji Yu's shoulders and taught him how to place the gun. If he aimed, with the help of Song Jining, Ji Yu, who shot for the first time, actually hit the bull's-eye.

Zhou Ziyi next to him widened his eyes and asked enviously, "Song Jining, can you teach me too?"

"Okay." Song Jining went to teach Zhou Ziyi.When other students saw this, they also asked Song Jining for guidance.

Although the instructor is right next to him, the instructor always feels uncomfortable. Song Jining is a classmate, so he is more comfortable looking for him, and he doesn't feel ashamed if he shoots crookedly.

So after a target shooting training, Song Jining successfully integrated into the class.

The empty cartridges given by the army are sufficient, and the students are allowed to play without restriction, and the teacher doesn't care.After letting them play for an hour, Teacher Zhu summoned the students again: "Okay, okay, the target shooting training is over, put away the guns, and stand in line!"

The students quickly put away their guns and lined up. Teacher Zhu stood in front of the line and asked, "Students, are guns fun?"

"It's fun!" The students all laughed and laughed like never before.

"Very well, do you all understand the structure of the gun?"

"learn!"

"Do you understand the gunshots?"

"Yes..." Some people instinctively wanted to answer, but they were stunned when they opened their mouths.

Know about gunshots?

What do you mean?

Teacher Zhu squinted his eyes and smiled, clapping his hands: "Okay, let's start today's second lesson, how to locate gunshots!"

Before that, Ji Chen felt that what he learned in the Air Guidance Institute was too basic. Of course, because the students in the class had zero foundation and zero common sense, they had to learn from scratch.But after training at this level, it will not be of much use until the end. At most, it is just "knowing more than ordinary people", and there is still a long way to go from a technician.

Even though the recent internship courses have become more and more difficult, Ji Chen feels that it is not enough. After completing the courses, they can at most undertake some basic equipment maintenance work.If you just want maintenance technicians, you don't need to find students like them for training. Any number of industrial schools can recruit technicians with professional education.

Hearing Teacher Zhu say what class he was going to have today, Ji Yu nodded secretly.

Finally started, this is what they should really be taught.

As soon as Mr. Zhu finished his second lesson today, someone immediately asked curiously, "Teacher, what is gunshot location?"

"As the name suggests, it is based on the gunshots to find its shooting position. But..." A truck drove in behind Mr. Zhu, and various instruments were moved to the open space by soldiers of the army. His eyes swept over the curious students, and finally stopped at Ji Yu's calm face: "I don't want you to listen with your ears, but to make such ears."

In fact, the full name of this class should be called "Gun Sound Location System".

It sounds very powerful, but you still find it difficult. How to locate the gunshot?

But to put it bluntly, it is to analyze the physical phenomena of the projectile shock wave and muzzle wave generated when the supersonic projectile is fired, and find the location of the gunshot through signal processing, signal identification, positioning and calculation and other technologies.

This technology currently belongs to a branch of radar technology, but its development to later generations is almost related to the outcome of sniper warfare.

Compared with simply learning theoretical knowledge and maintenance knowledge, such courses are what they should learn most.

Teacher Zhu stood in the open space and explained the main principles of the gunshot location system to them in detail. After the students understood, he waved his hand: "Okay, I have prepared enough materials for you, I hope you can base them on Based on my own understanding, I created a gun sound positioning system.”

The gunshot positioning system includes digital and analog signal technology, digital communication technology and so on.Teacher Zhu didn't explain these things, and the students didn't need him to explain them. This is something they should have understood a long time ago.If they didn't even know how to convert mathematical signals after learning now, they should have packed their bags and gone home long ago.

But even though they understand it in theory, without reference, they are only allowed to explore according to their own ideas, and the things they make are naturally not standard.

Some have been made into small radars, some have been made into microphones, and after some people have completed them, the instrument actually emits singing——accidentally made a radio.

Ji Chen knew what he should do.

A dedicated positioning system for anti-sniper warfare in later generations.

Of course, given the current state of technology, it's not that perfect.Anyway, he just put forward such a concept, whether it can be successfully manufactured at that time, someone will study it.

After making up his mind, when Ji Yu took the tools and materials he had chosen to prepare for work, Song Jining came over and asked him: "Yuanyuan, what do you want to do?" Before he could answer, Song Jining had already said: "Listen The principle of this thing seems to be a radar, but I don’t think it’s suitable, it already has a radar, so what’s the point of making a gun sound positioning system?”

Ji Yu was stunned: "Then what do you think brother Song should do?"

"When we used to train, we often ambushed each other. As soon as Mr. Zhu mentioned the principle of the gunshot, I thought it should be used in counter-sniping. If there is a sniper, the positioning system can immediately locate the position of the sniper, and I can Make a counterattack on the spot." Song Jining compared a shooting posture by himself: "I lost to Ji Yong once because I didn't know his position. At that time, I thought, it would be great to have such a thing."

Ji Yu was speechless, looking at Song Jining with admiration.

Because he came from later generations, he has some understanding of this positioning system, otherwise he would only make a small radar.Brother Xiao Song found the right direction of development just by relying on the training of the little red soldiers when he was young.It is no wonder that he will have later achievements, you must know that he was retired from the special forces at that time.

As for whether Xiao Song, who has never been a soldier, can still achieve future achievements, Ji Chen is not worried.

Brother Song is only in his twenties now. The major he is studying, the papers he has published, and the contacts he has made are all much higher than his later teachers, and he has never wasted his talents. He is working hard every day, so he Your future achievements will only be higher than your teacher.

Professor Zhu walked past the equipment made by the students, smiling while scoring.He has the equipment of the gun sound location system in his hand, but he doesn't plan to take it out for the time being.The principle of this set of equipment is simple, and then see the real thing,

The author has something to say: This group of students can definitely make a new one without any mistakes.But what he wants to test more is the imagination and creativity of the students. If he just wants them to imitate, he might as well go to the military factory to find workers to do it.

Helplessly, although these students are all talented, they still don't know enough about military industry, their imagination is a bit weak, and the things they make are mostly civilian products.

But this is only the first class, and they have already performed well, at least the things they made are usable finished products.

Until, he came to Song Jining.
