Military Industry of Great Powers: Build the Strongest Flanker

In the Foreign Journals Room of the Xidian Library, the debate was still going on. Zhao Guoqing was also feeling very comfortable. Discussing with the old man, he felt like he had learned something about himself.

In fact, even yesterday, this knowledge was very unfamiliar to him, but now, he has a deeper understanding of some of the knowledge.

"Radar must be miniaturized and powerful, and it can only rely on semiconductors. Foreign research in this area has been very in-depth!"

"But what I understand is that the biggest problem with the application of semiconductors in radar is unreliability. You must know that radars are mostly created for the military. If the equipment is unreliable, it is often fatal. After half a century of development, electronic tubes , the technology is still worthy of trust, as long as the difficulty of miniaturization of electron tubes can be solved, the problem will naturally be solved..."

Zhao Guoqing felt that this old man was just trying to take the argument. Of course, the path the old man said was also the path Lao Maozi was taking now, and of course it also represented the views of a large group of people.

The Russians are very stubborn and have continued this path into the 21st century. Finally, they built a 1.5-ton passive phased array radar on the Su-27. As for the active phased array, even by 2023, Lao Maozi didn't make anything that could get on a plane.

The same active phased array radar from China and the United States, including the cooling system, only weighs more than 500 kilograms, and its performance is still better than that of Lao Maozi. So much so that the J-10 fighter jet imitating the Su-27 was modified with an active phased array radar. At that time, in order to maintain the balance of the structure, counterweights had to be added...

"There is no future for the miniaturization of electron tubes. No matter how high the density of tube integrated circuits is, it cannot be higher than that of transistors. Silicon-based chips have shown strong digital computing potential. There are so many P-group elements, and there are dozens of compound crystals composed of them. , there is a big reason why the energy gap is higher than that of silicon. Only if we can find crystals with an energy gap greater than 2.8 electron volts, these can be easily solved!"

"..."

There was a slight blush on the old man's face, and he didn't know whether it was excitement or something else. In fact, the country's academic circles also had different opinions on whether to continue to study electron tubes or to turn to transistors.

The country was developing transistors in the 1960s, but after more than 20 years, by the 1980s, it was far behind the world. It was like a brand new field. There was no doubt that the risks were very high when exploring here, especially It's military speaking.

The old man looked at Zhao Guoqing and secretly sighed that being young is good and he is academically solid. He originally meant to take exams, but now he is still in a position of equal communication. After thinking about it, he continued to ask: "Rhetoric, talk. Have you ever had any arguments?"

Zhao Guoqing opened the journal in his hand and smiled: "Gallium arsenide crystal has been proven to have high frequency, radiation resistance, and high temperature resistance. Indium telluride crystal has excellent infrared sensitivity. If it is made into an array, it can be used for guidance. …”

Director Wang from Institute 14 looked at Director Liu next to him with an incredible look in his eyes.

They couldn't understand the interview more and more. What was gallium arsenide, what was indium telluride, it was an array, it was a guide, it had something to do with radar, but it didn't seem to have anything to do with it. Are Xidian's college students so awesome? It seems that the few people recruited last year were not so crazy.

What kind of person is Mr. Jin? He is the Beidou in the domestic radio field. He taught at Tsingta University when the People's Republic of China was founded. Even if he was delayed for several years, his academic status would not be affected.

This Zhao Guoqing actually made Mr. Jin speechless...

Director Wang looked at Yang Qing next to him. In fact, the 14th Institute had long since taken a fancy to Yang Qing. He knew both Russian and technology. The 14th Institute was in great need of such talents. However, they had no intention of doing so and there was nothing they could do about it. The two of them I originally went to find Yang Jianguo and contact Zhao Guoqing, but failed. Then I met Yang Qing by chance and was brought here.

And Yang Qing was also flustered, struggling with what Zhao Guoqing had said, that he was afraid of missing her, and didn't know how to face it. He thought of bringing her over and leaving, but she didn't expect to see such a debate, and she didn't understand the knowledge involved. !

"call!"

Mr. Jin took a long breath and listened to Zhao Guoqing continue: "Semiconductor transistors are very difficult, involving materials, optics, etching, packaging, wafers, lasers, organic films... the entire industry chain. We are already lagging behind. If we still If we don’t catch up, the gap will get wider and wider, we can’t wait any longer!”

The gap is getting bigger and bigger!

Yes, the gap will get bigger and bigger!

Many people in academia have seen the huge potential of semiconductors.

It's not that Mr. Jin can't see it, but the country is in dire straits and there are too many places where money needs to be spent. The top management is also worried about whether the country will be dragged down by this industry.

At this time, someone came up and shouted: "Mr. Jin, why are you here and you didn't tell me in advance!"

Mr. Jin?

Zhao Guoqing was stunned. He turned around and saw a large group of people gathered around him. Wu Hongbo, the principal of Xidian, was at the front. He quickly stepped forward and was busy saying hello to the old man.

He wisely stepped aside and looked at the old man, thinking that Mr. Jin could be Academician Jin Xiangnan.

Regarding Academician Jin, Zhao Guoqing was not very familiar with him. Jin Xiangnan was not well-known in the academic world, but thirty years later, he had a disciple named Shen Yiwei, who was a master of radar and electromagnetic waves.

The meter-wave active phased array radar developed by Shen Yiwei has raised the level of national vehicle radar to an internationally leading level.

In 2020, a wealthy man from the Middle East imported several domestically produced meter-wave radar vehicles and successfully identified F22 fighter jets taking off and landing at a US military base 200 kilometers away.

At that time, the rich guy didn't know whether he was being willful or just wanted to make a joke with the old Americans. After the meter wave radar truck locked on the F22 stealth fighter, he also turned on the ground fire control radar and illuminated it for 30 seconds, which scared the pilot of the F22 fighter at that time. I made an emergency landing at a civilian airport and was left in disgrace.

You must know that when locked by a fire control radar, even a stealth fighter like the F22 has an extremely low chance of survival.

This incident caused great shock within the US military and triggered a debate on whether to study stealth fighter jets.

From that moment on, the U.S. military felt that the battlefield had been exposed.

In my memory, Zhao Guoqing also participated in this debate, and Locke Martin's Skunk Works participated in the demonstration. At that time, the development of the "Tear Project" sixth-generation super-stealth fighter that Zhao Guoqing participated in was also questioned at the time.

The Americans spent a lot of money to find out the name Shen Yiwei, which has impressed Zhao Guoqing so far. At the same time, it also made him remember the name of Academician Jin Xiangnan!

Thinking about it makes me very passionate!

"Xiao Wu, your school is really a hidden dragon and a crouching tiger. It should not be underestimated!"

Principal Wu looked at Zhao Guoqing, and the two looked at each other. The school student was praised by Mr. Jin, and he was proud of himself. Although the debate just now was coming to an end, it could still be called a wonderful one.

Zhao Guoqing has seen big storms. He is just meeting the principal. Even if he is Mr. Jin, he has respect, but he will definitely not feel cramped. It is not an exaggeration to say that he is as motionless as a mountain.

And this temperament slowly magnified in Principal Wu's eyes, and his brows rose slightly. This young man is amazing!
