Military Industry of Great Powers: Build the Strongest Flanker

I can’t understand it. Mr. Bi said I can’t understand it. In terms of logical operations, domestic computers are still stuck in purely scientific operations such as shifts and NAND.

Zhao Guoqing introduced an instruction set system to these thousands of logic gate circuits. Although there are only thirteen streamlined instructions, it has broken out of the scope of scientific operations and involved some logical operations, as well as some analog signals and numbers. Logical conversion of signals.

On the system diagram, you can clearly see the purpose of this circuit.

"This is the radar lock circuit!"

It involves three items, one is to remove interference and lock the target, the second is to calculate the accurate positioning of the target, and the third is to drive the radar antenna to enhance scanning of the target airspace and switch to the gaze state at any time.

"Gaze state? This circuit can also be used on fighter planes."

But looking at the drawings again, Engineer Bi sighed and shook his head.

Although the circuit is exquisite, the logic locking method is also very scientific, and the reliability of the argument should be no problem.

But there's only one problem.

"More than a thousand logic gates involve tens of thousands of diodes and transistors. Thousands of current amplifying transistors are needed. I'm afraid it requires three kilowatts of power. If the corresponding power supply circuit is added, it will be a huge thing. It will cost several tons. !”

Zhao Guoqing nodded. Engineer Bi's estimate was correct. With the domestic manufacturing technology, it would be impossible to make a three- to five-ton truck. With the addition of the antenna and motor drive system, the weight would double. With this weight, it would be useless to make it. I can't get into a car, let alone a plane.

With Maoxiong's design capabilities, it will only be reduced to one and a half tons in ten years, and many of its components are plagiarized Western transistor chips.

"Within two hundred pounds!"

"Within two hundred pounds? Impossible, there is no way to do it. Domestic tubes can only reach 0.3 mm at most. No matter how small the performance is, the performance cannot be guaranteed. The breakdown voltage does not meet the requirements..."

Zhao Guoqing turned to the third drawing. Compared with the second drawing, the third drawing was more concise and clear. Each small square represented the aesthetics of the ultra-electric circuit. The links between these devices were arranged through pencil drawings.

Even General Engineer Bi had difficulty reading, and the college students who came in all around couldn't understand it at all.

"This is a chip integrated circuit..."

…………

Institute 53 is a fighter aircraft assembly design, mainly focusing on the aerodynamic shape of the fighter aircraft.

The design of the aerodynamic shape is restricted by the engine shape and performance. In fact, after the aerodynamic shape is roughly determined, it is time to design avionics, flight control, weapon systems, radar and infrared equipment, etc.

Although the appearance is determined first, various airborne equipment are then designed based on the appearance.

But often the process is not like this.

Various extreme equipment often have special requirements for installation space and circuits, which in turn restricts modifications to the aerodynamic shape.

Four years ago, the country’s latest J-72 entered service. The J-72 had a fatal shortcoming. It did not have all-weather combat capabilities due to backward avionics technology.

After equipping the army, the main task of each institute is to design modifications to the J-7 so that the J-7 can have all-weather combat capabilities. The headquarters has already sent people to negotiate with Yingjiang.

In fact, many teams were sent, including Rolls-Royce in England, Dassault in France, and even Boeing sent people to inspect.

The people at the headquarters are also very confused now. They have three ideas. One is to buy it directly, the other is to introduce the engine and avionics and build it yourself, and the third is to improve it on the basis of the J-7.

Under such an environment, Institute 53 naturally panicked.

This time I came to No. 14, firstly to check the progress of work on the airborne radar at No. 14, and secondly, to discuss the next step.

Lu Zhen, the deputy chief engineer of the J-7 Kaifa, said unceremoniously: "What's going on with Lao Bi? The airborne radar belongs to the third group of them, and one of his clients has escaped. How can we still open the meeting now!"

Director Gao couldn't help but said to Director Liu, "What's going on?"

At the meeting, Director Liu's face was twisted.

"A new college student is here. The drawings are quite good. Chief Engineer Bi said he will come later!"

"It's not because there's no progress in research and you don't dare to see us!"

Director Gao's face darkened, and the chief engineer of the 14th institute who attended the meeting also looked ugly. How could an old military engineer be a deserter, but in the current scene, it was not easy for them to argue.

What kind of drawings can a newly arrived college student draw? If he can understand the drawings, he is already very good.

For this reason, they all felt blushing!

"Old Liu, go ahead and shout again!"

"good!"

Deputy Chief Lu stood up, waved his hand and said, "No need, I'll go with you to see what Lao Bi is up to!"

The honeymoon period with the West has had a profound impact on China. It has allowed China to see the advanced technology of the West, which is positive.

At the same time, the negative side is also great. The failure of those major projects will have a profound impact on China's engineering personnel.

The huge gap has caused many people to lose their fighting spirit, and hearsay about the introduction of equipment has also caused many people to lose their enthusiasm for the research and development of these low-index equipment.

Rolls-Royce's PPLK airborne radar can detect more than 100 kilometers and weighs only 700 to 900 kilograms. It is much better than the technical indicators proposed by the military.

If you can buy it, why go to research and development? It is better to wait for the equipment to be introduced and then do familiar reverse engineering.

Many people think this way, but in the view of Deputy Chief Luo, this idea is very dangerous.

"You cannot pin your national defense career on the generosity of your opponent, even if the opponent at this time is also your current ally."

"The Mao Xiong is unreliable, and the West is not reliable either. Our comrades, we must see this clearly!"

Deputy General Engineer Lu was worried, and he still valued General Engineer Bi.

"I hope he won't be so confused!"

In just a few minutes, I arrived at the entrance of the cave. Under the dim light, I kept walking inside. Before I reached the end, I heard the voice of Chief Engineer Bi...

…

"Xiao Zhao, we must seek truth from facts when doing scientific research. We cannot just rely on a foreign paper and regard it as the truth. Can this gallium nitride semiconductor have such performance? If it cannot be made, the impact will not be immediate. It’s a radar!”

There is a lot of confidential information, and it is difficult for Mr. Bi to tell it or make it happen. If the project of the 14th Institute is canceled, the entire fighter jet project will not progress, and the impact will be huge.

Zhao Guoqing had a tough tone. At this time, he had to stick to himself and analyze the feasibility of gallium nitride compound crystals from the atomic level based on the properties of nitrogen and gallium element trivalents.

"The gap voltage has proven the excellent hole and electron migration properties of gallium nitride. This material is definitely feasible!"

Zhao Guoqing even used the method used to study P-group elements thirty years later, which involved part of quantum mechanics and strong and weak motion at the molecular level.

This has seriously departed from the scope of Bi's research.

Zhao Guoqing was also anxious. General Engineer Bi was worried about gains and losses, so he naturally had his reasons, but if the 14 institutes couldn't reach a consensus, how could he fight for resources with the people at the headquarters.

"We are doing research abroad. If we don't do research, we will die. If we do research, we might still have a chance to succeed!"

As soon as he finished speaking, he heard someone at the door say loudly "Okay!"

"Young people should be like this and have the courage to move forward."
