country made

Ji Yu didn't participate in Song Jining's production, nor did he help.This is like an exam, he can't help, and he also wants to see Song Jining's own level.

Then, Song Jining made something that did not lose him.

The principle of the gun sound positioning system he made coincides with Ji Yu's, but in appearance, due to the limited technical level, it took three signal converters to convert it into a positioning system, and the appearance became three connected small Radar, failed to achieve the expected portable effect.

When Mr. Zhu walked up to him, he couldn't help smiling and asked, "What is this? Radar? Audio?"

"Report teacher, this is the gunshot positioning system."

"How did you make three... well, show me your blueprint."

The design drawing is a bit messy, and Song Jining changed it several times on the line, but the overall design ideas and applications can still be seen.Teacher Zhu, who was originally smiling, froze for a moment, restrained his smile, and looked seriously: "Explain your design ideas."

"Yes!"

Song Jining put forward the idea that the gun sound location system should be used in sniper warfare, which aroused the interest of the officers and soldiers nearby, and they gradually gathered around to listen to his explanation, nodding their heads in agreement with him from time to time.

After Song Jining finished explaining, the army commander nodded: "This kid knows guerrilla warfare quite well. If there is such a thing, it will be easy for us to fight the monkeys in Laoshan and Yueguo! How about Dr. Zhu, this thing can be studied come out?"

Teacher Zhu nodded: "It's useless to talk about it, let's test it first."

It was originally just a small homework, just look at the design drawings to see if it was successful, but since the troops were interested, Teacher Zhu asked them to take it to the woods for a try.

With a gunshot, there was a beeping sound in the woods. After a while, two soldiers came out to report: "Report, there is a 5-meter error between the instrument display and the shooting location."

Song Jining lowered his shoulders regretfully.You can't hit the enemy with a difference of 1 meter, let alone an error of 5 meters.

Teacher Zhu is interested in another thing: "How is the reaction speed of gunshot positioning?"

"About ten seconds."

Teacher Zhu clapped his hands: "It's very good, you can study it in this direction...Song Jining, go back and draw a complete design for me..."

In fact, he doesn't need a student to draw a design for him, but the original design principle comes from Song Jining, he can't take advantage of a student, let him write a design, and when the project is approved, he will add a name.

The praise that Song Jining received caused a commotion among the students who were not checked. Everyone was eager to try, hoping that the equipment they made would also be a blockbuster.It's a pity that most people make small radars that are quite satisfactory, and there is nothing special about them.

Teacher Zhu quickly came to Ji Yu's desk and saw a palm-sized instrument.The style is also a bit like a small radar, but it is not the same, so he said: "Ji Yu, give me the blueprint, and tell me about your design ideas."

Ji Yu is also a self-made gun sound positioning system. Compared with Song Jining, his is already a semi-finished product.However, due to the material of the equipment, this thing is a bit big, and it is still not suitable for carrying.

Teacher Zhu was stunned when he saw the drawing. This sketch is relatively more complete than other people's. The design ideas, formulas used, circuit design, and signal conversion values ​​are all written in detail.The design idea is the same as Song Jining's, but it looks like his complete version.

"Did you discuss it with Song Jining?"

Ji Yu shook his head: "No, we each think about it."

"You really have a tacit understanding. Platoon Leader Zhang, you can test it."

Two soldiers were ordered to take the equipment to the woods for testing. Shortly after the gunshot, the two soldiers came out with a dazed expression.

"How is it?" Platoon Leader Zhang asked.

"Hmm... ah, report!" The two soldiers came back to their senses, with a look of interest on their faces: "It's located, so fast, the location where Xiao Zhao is hiding is located as soon as he shoots!"

"Oh? What about the error?"

"The error is within 1 meter."

The materials made are not precision components, so naturally they are not so perfect. A 1-meter error is considered a huge mistake in sniper warfare, but as long as it is adjusted properly and then replaced with precision components, it can basically achieve accurate positioning.

The most difficult problem of this technology is the "precise positioning". Even if Ji Chen can study it by himself, he can't study it. The gap between the times is not only the technology, but also many important components.However, there are so many excellent technicians in the country, I believe that given them some time, they will be able to research. Ji Yu never doubts the scientific research capabilities of this country.

Teacher Zhu took this instrument and looked at it, then looked at the complete drawing, and said with appreciation: "This is already a semi-finished product, Ji Yu, it's amazing..."

Compared with Ji Yu's, Song Jining's is not enough.But Mr. Zhu had already told Song Jining before that it was not easy to change, so he had to say to Ji Yu: "You can also draw a complete design drawing for me when you go back, and it is best to write a paper."

Forget it, add both names.

Song Jining didn't know that Mr. Zhu asked him to draw the design drawings to give him a name when he started the project in the future, and he just took it as homework to complete.Zhou Ziyi and other students also didn't understand, they also asked curiously: "Song Jining, Ji Yu, what does the teacher want your drawings for?"

"Maybe it's homework after class!" Song Jining said indifferently with the tip of his pen in his mouth: "Like a composition, should it be posted on the blackboard behind the classroom?"

"Impossible, and we don't have a blackboard newspaper!" The classroom they teach is similar to a lecture theater in a university, and there is no such thing as a blackboard newspaper.

Song Jining shrugged: "That is to recommend publishing a paper, isn't Ji Yu asked to write a paper?" He turned to Ji Yu: "Right, Yuanyuan?"

Ji Chen couldn't tell them the truth, but just nodded: "Maybe, it would be great if it could be published."

A few days later, when the two of them handed over the design drawings and thesis to Mr. Zhu, they heard him say: "I will apply for a research project based on your design, and if I pass it, I will write it on the file. Write down your names."

"Oh, whatever you want!" Song Jining was not interested in such false names, so he said casually.

Ji Yu just nodded: "I wish the teacher can pass the project review."

He also doesn't care about these things, he just hopes that the higher authorities can pass the approval, so that the technology of later generations can come out in advance, adding strength to the armament.

After this course, everyone spent less and less time in the classroom, more and more time in the laboratory or armament area, and what they learned was more and more military-intensive.Ji Yu has learned many technologies that later generations will not learn. The machinery and instruments of later generations are very advanced, and people are more accustomed to relying on machinery.But the old technicians of this era almost rely on pure manual skills. Basically, if they are given any tool, there is nothing they cannot transform.

When Ji Yu saw the story of "a technician knocked out a mechanical part by hand", he wondered if it was just a chicken soup article written by someone.He no longer doubts that technicians of this era can really do it.

When the training was coming to an end, Ji Yu and Song Jining suddenly received a transfer order.
