Military Industry of Great Powers: Build the Strongest Flanker.

Chapter 38 Unprecedented
This is the benefit brought by the honeymoon period between China and the West.

The Weishe 15 short-range air-to-air missile has an attack range of 5 kilometers, infrared guidance and radar guidance, and can conduct beyond-visual-range combat, with a non-escape distance of [-] kilometers.

Compared with air-to-air missiles 40 years later, the guidance form is single and the technical indicators are insufficient. Forty years later, air-to-air missiles are already multi-guided, equipped with active active phased radar, photoelectric guidance and high-sensitivity infrared guidance. The no-escape distance is higher than its attack range.

But at this time, it is already the world's leading weapon.

What makes Zhao Guoqing speechless is that the bus standard of the Weishe San air-to-air missile uses the American 1553b data bus.

Zhao Guoqing thought to himself: "Now 1553D is no longer needed, so I will go directly to 1553B."

Gao Changming said: "National Day, how about it? Can you do it?"

Zhao Guoqing nodded. He didn't need to be familiar with 1553B. He didn't need to read the technical regulations to do it. The key was that he was too familiar with it. He had basically studied this thing for 30 years.

"National Day, don't be careless, this thing is not cheap!"

After all, Zhao Guoqing was young. Gao Changming was a little worried that this kid would do it forcefully and reminded him.

Everyone in the military industry knows that one piece of this thing costs 10,000+ US dollars. Although from the exchange rate point of view, it is about 50 yuan. In fact, the national exchange rate has not been liberalized yet. According to the actual purchasing power, one piece costs 150 million yuan. .

The total price of the entire Monster Snake III project was more than 5 million US dollars. This money could buy thirty or forty F16s, and it cost one-third of the country's foreign exchange reserves at the time.

The price is several times higher than what the Jewish state sells to other countries, so much so that some people say that the Jewish state is cheating us.

In fact, this arms purchase also covers a requirement, that is, the Jewish state needs to transfer all technologies. This is what the country values ​​most.

How to digest these technologies is now a headache for various units across the country. Although Youguo has signed the contract, it is still very cautious about the core flight control technology, data transmission radio frequency technology, and the core infrared photosensitive CCD technology. It was not handed over to us at this time, but we were only willing to provide part of the launch terminal fire control device.

One consequence of this is that there are not enough launch platforms for the more than [-] Weishe III short-range air-to-air missiles introduced.

"Can Xiao Zhao solve it?" Gao Changming was unsure, but the impossibility that Zhao Guoqing brought to him gave him some hope.

"What if it succeeds!"

When I arrived at Zhao Guoqing's side, I felt much more at ease after seeing the technical information on the Wei Snake III short-range air-to-air missile.

Once the design requirements are confirmed, the next steps will be much easier.

The chip that assists calculations adopts programmable DSP (digital signal processing) design ideas.

Compared with the CPU used in microcomputers, the function of the auxiliary computing DSP is much simpler.

Its main function is scientific calculation.

Zhao Guoqing looked at the drawing board and laughed dumbly. He never thought that one day he would be able to rub the processor with his hands.

Fortunately, there are relatively few transistors involved, only 2000 transistors, which is similar to the 4004 processor and uses 8-bit data.

Military chips do not need to be advanced, but they need to be durable and capable of assisting calculations with DSP, which can also be used using a ten-micron process.

The reason why 8-bit data processing is used is because the fire control system for guiding air-to-air missiles does not require high accuracy at all. Therefore, in terms of calculation, what is required is to quickly calculate approximate results.

The reason is that radar guidance is only beyond-visual-range guidance, which guides air-to-air missiles to approach the target. Within three kilometers of the target, infrared guidance can be activated. By that time, radar guidance is no longer needed. The radar can track whether the target has been destroyed. .

"How about it?"

"The computing auxiliary chip is almost ready!"

"..."

"National Day, do you want to take a rest?"

Even Gao Changming had to give a thumbs up. In three days, he spent three days in the laboratory. Apart from going to the toilet, he even stayed in the drawing room to eat. His enthusiasm for work was gone.

"National Day, even when I was young I couldn't compare to you!"

Zhao Guoqing looked slightly tired. To be honest, such an 8-bit scientific computing DSP could be completed in minutes if there was EDA design software, but it took him three days.

Including chip microcode, logical system diagram (architectural logic design), and the most arduous physical drawings.

On a piece of paper, draw two thousand transistors one by one, as well as the connected wire circuits... This is not something that just anyone can do.

Gao Changming shook his head and said with a wry smile: "This is almost like a city, with roads... and houses... National Day, thank you for your hard work!"

Looking at this drawing, Zhao Guoqing felt quite satisfied. He shook his head and said, "Only one-thirtieth of the work has been completed!" "Ah, one-thirtieth?"

Zhao Guoqing said: "The auxiliary computing chip is the simplest. There are also more complex ADC (analog-to-digital) chips and DAC (digital-to-analog) chips. In particular, the DAC chip involves the communication between auxiliary computing and fire control radar. , and communication control with air-to-air missiles. If you want to add a cannon, it will make the work more difficult!"

"..."

Zhao Guoqing took a mouthful of rice. The rice was already cold. It was covered with a piece of pork. It was red and red and looked delicious.

"National Day, wait a minute, I'll heat up the food!"

"It's okay, I'm in a hurry!"

"Listen to me, this is an order!"

"All right!"

Ten minutes later, when Director Gao delivered the hot rice to the drawing room, he saw Zhao Guoqing lying on the table and falling asleep, drooling all over the table with some rice grains and vegetable scraps.

Director Gao's eyes suddenly turned red. He took out a handkerchief from his pocket, wiped off the saliva, and put his coat on Zhao Guoqing.

He had experienced this kind of enthusiasm for work, but it had been many years ago. He cherished the sun like gold and was full of deep patriotism and a sense of urgency.

What Director Gao doesn't know is that without this enthusiasm and will, how could Zhao Guoqing in another time and space have maintained his 40 years of loneliness.

"If I quit my job as director, I will build this laboratory for you!"

Gao Changming came to Liu Guoqiang's office.

Liu Guoqiang saw that Gao Changming's mood was not right, so he quickly asked: "What's wrong, Changming, is it not going well? By the way, why didn't you see that follower of yours?"

"National Day is not my follower!"

"..."

"Make a call!"

Liu Guoqiang looked at Gao Changmin, nodded and said, "Okay!" After that, he walked out of the office and closed the door.

"Director Liu, I am Gao Changming!"

"Hello, Changming! How are you doing? Is everything going well?"

"Everything goes well, and preliminary results have been achieved!"

Director Liu Qing's voice suddenly rose and he said, "There are results, what are the results?"

Gao Changming spent 10 minutes briefly reporting the situation before he said: "Director Liu, how can such a big project be done by Guo Qing alone? I suggest that the General Office come forward and convene a group of semiconductor experts. , assist Zhao Guoqing to complete..."

"You mean to ask Xiao Zhao to take the lead in this project? He is only 22 years old and has just graduated..."

"Director Liu, at the age of 22, he broke the technology monopoly of foreign high-purity gallium nitride, and the results of light-emitting semiconductors are also very fast. What's wrong?"

"Changming, I'm not saying that National Day is not capable enough, but I'm afraid that he doesn't have the prestige and can't lead the leadership! Let's do this. I'll let Chief Engineer Ji Hongbo of CLP take the lead, and Xiao Zhao will be the temporary deputy to take charge of the work. You What do you think?"

"Director Liu is very considerate!"

Liu Qing thought for a while and said: "Chang Ming, the official appointment will not be issued until after the verification of the computing auxiliary chip you mentioned. Do you have any objection?"

"I have no opinion!"

"Okay, the expert team will arrive at Z Airlines soon. Just wait a few days!"

"it is good!"

Gao Changming put down the phone.

Good guy, although he is temporary, he is still at the level of deputy chief engineer. This three-jump jump is unprecedented.

As for whether the computing auxiliary chip could pass the demonstration, Gao Changming never thought about failure. He himself did not realize that he had given the purest trust to this young man.
