Chapter 178 An extra-large fly swatter carrying a pole (Additional update 1)

 Kuznetsov?

This name should be very common among Lao Maozi. Just like Xiao Ming and Xiao Hong in China, many people call him Kuznetsov. As for the guy in front of him who wears thick glasses and has bald hair, He is the developer and chief engineer of the long-range radar in the S-300 system, Ю.А.Кузнецов!

(I found two people, and one of them didn’t know how to translate it. When I searched it on Baidu, what came up was a bunch of letters mixed with the word sweet and sour pork, so I had to give up.)

"Mr. Kuznetsov, I am very happy to meet you. My name is Qin, and this is my wife Zhao. We are all good friends of Nikolai. We are returning to the Far East with Nikolai. We pass by here and come in to take a look. , this is a small gift, not respectful."

Qin Tao waved his hand, and Zaitsev, who was always inseparable, came over holding a box.

When he saw the small black blocks stuck on the foam inside the box, with English letters on them, Kuznetsov's face showed shock, excitement, excitement, and gratitude... With trembling hands, he A piece was carefully picked up inside.

 Sure enough, it is very important to give them what they like. For these scientific and technological workers, it is more meaningful to give them technical things.

At the Gas Turbine Design Bureau, Qin Tao sent a batch of graphics computers, and now, these small black blocks given to Kuznetsov are integrated circuits!

“Are these purchased from the United States?” Kuznetsov asked, his words still trembling.

Qin Tao shook his head: "No, although the logo above is in English letters, in fact, these integrated circuits are produced by ourselves. However, we named them after the same model of integrated circuits in the United States. We use these integrated circuits We can reversely estimate the functions and then develop an integrated circuit with the same performance ourselves.”

 Speaking of integrated circuits, that is, chips, countless people always lament that the quality of domestic chips is too poor and the gap between them and the West is too big, etc.

In the field of civilian chips, this is indeed the case. After the Computer Institute of the Chinese Academy of Sciences gave up the research and development of very large-scale integrated circuits, the gap with the world quickly widened. In later generations, although they have been catching up, the gap with the West is still quite large. big.

 But, that is only for civilian use.

 In the field of civilian chips, what matters is performance, so the manufacturing process is becoming more and more advanced. Before Qin Tao crossed over, there were already 7-nanometer and 5-nanometer technologies, which shows the strength of the West in these fields.

So, what about the military ones?

 Military and civilian use are completely different.

Although in the early days, Americans used to put civilian 8080 processors into their Tomcat fighter radars, and Americans also used IBM's civilian minicomputers for their Aegis system, which had It's Motorola 68000. However, it was just for the initial stage.

Military chips do not have that high demand for manufacturing processes. While civilian mobile phone chips have begun to advance towards 5 nanometers, military chips are still a few generations behind with 28 nanometers or even 50 nanometers, which is no problem. 5nm is not suitable. An electromagnetic pulse can burn this advanced chip.

 Military chips cannot be used abroad. If there is a backdoor or something, big trouble will happen on the battlefield.

 At present, the active phased array radar technology that 14 institutes are working on is essentially electronic technology. Each T/R component is a microelectronic product.

As for integrated circuits, they are also available in China. There are 23 institutes located deep in the mountains. They have been engaged in related technologies and have achieved many achievements.

For example, China's first PMOS large-scale integrated circuit (LSI)-120-bit MOS shift register successfully realized the leap from small and medium-sized integrated circuits to large-scale integrated circuits; the first 1K, 4K static memory, the first ECL circuit S12, the first generation operational amplifier series, the first color TV complete circuit series; the first A/D, D/A converter, the first batch of anti-add analog circuits, etc.

What Qin Tao brought now are the products of the 24th Institute. Compared with the advanced military chips in the West, these chips are not worth mentioning, and they are still backward. However, if compared with Lao Maozi, they are nothing. It is inferior, and even has some advantages.

After all, after entering the 1980s, China had introduced chip technology from the West and proposed the 531 plan, but Lao Maozi no longer had this opportunity.

(I wrote about a CNC machine tool earlier. We already started working on it in the 1990s. It is just a test prototype. It will take a long time to mature, but it can be used. The same is true for these integrated circuits. Domestic ones will definitely not be able to compare. Imported, but if we can produce it ourselves, we can use it with confidence. Of course, it will take thirty years of hard work to truly catch up with the West. In order to increase the convincingness, let me say one more thing. After the S-300 is imported, Our technicians took it apart and researched it, and found that the technology used in Lao Maozi is lagging behind ours. However, Lao Maozi’s integration ability is really strong. It is obviously a bunch of backward parts, but after being saved, it is very easy to use.)

At this time, when he heard Qin Tao mention that these chips were produced in China, Kuznetsov opened his mouth wide: "This is impossible!"

"Mr. Kuznetsov, you are a technical person, you shouldn't be so arbitrary, right? If we didn't produce them ourselves, how could I have obtained these integrated circuits so easily? Some of these models have been banned from being sold to us by the West. Sorry, our domestic inventory is only one piece less if you use one piece, so why would we be willing to give it to you?"

 What Qin Tao said is correct.

Kuznetsov looked at the black chips, and he was extremely shocked. After he saw all the models, he let out a long breath: "Can you produce these integrated circuits yourself? "

“Yes.” Qin Tao nodded: “So, you can use these integrated circuits in your equipment with confidence. Of course, if necessary, our technical experts can also come and help.”

 What does Qin Tao want to do?

Of course it’s joint research and development!

 It is already May of 1991. In a few months, the Red Empire will collapse. From now on, Lao Maozi will have a very difficult life.

This time Qin Tao came over to show off the integrated circuits produced by his side, just to lay the groundwork first. Now the other party will definitely not invite his own technical personnel to join the research, and even these integrated circuits may not be used. However, wait until next year. Years later, Lao Maozi will naturally think of these things, and maybe he will use them.

  (Some rumors say that S-300PMU1 was jointly developed by China and Russia.)

 At least for now, Qin Tao gave these integrated circuits to Kuznetsov and immediately gained his favor.

“Qin, thank you for giving us these integrated circuits. Since you are Nikolai’s friend, you are also a good friend of mine. Now, can I do something for you?”

Everything fell into place. Nicholas said with a smile: "Take us to see the big thing you developed."

"big guy?"

 “That’s right, it’s that extra-large fly swatter.”

"good."

 Plate-shaped phased array radars all look like fly swatters, but some are large and some are small. If there is one of the largest fly swatters for field air defense, it is definitely from the Novosibirsk Institute of Surveying Instruments.

Zhao Ling’s eyes widened when Kuznetsov led everyone through the front yard, into the backyard, and then came to an extra-large trailer.

After Zhao Ling graduated from college, she went to work on air defense missiles. Of course she knew how powerful this kind of large phased array radar was. There were also them in China. They were just fixed on a mountain as a strategic early warning radar. But here, this kind of large phased array radar was actually used. The radar was installed on the trailer.

"Currently, we are still developing. The later digital processing system is a big problem. If we use those integrated circuits, it may be of great help." Kuznetsov said: "Now, I can only give You deploy this radar."

Yes, the current radar is still folded and placed on the trailer. Kuznetsov entered a machine room at the rear of the trailer and operated it. The huge antenna array slowly stood up, and the folded parts on both sides stretched into a The plane, and then a huge pole, spanned both sides of the top of the antenna array.

“Is it a double-sided phased array?” Zhao Ling asked in surprise.

It must be a passive phased array. You can tell by looking at the phase shifter above. However, it is equivalent to two phased array radars back to back. This forms a huge antenna array. Even if it does not rotate, it can theoretically Has omnidirectional scanning capabilities. However, underneath it is obviously a 360-degree rotating axis.

 Is it necessary to use both sides?

"Yes, this arrangement can give it a stronger target refresh capability. In order to have a stronger search distance, the radar will mainly focus on the ninety-degree sector in front of it." These are not secrets, Ku Znetsov answered directly.

“This antenna array is larger than the Aegis system.” Qin Tao also expressed emotion: “It’s just that this big shoulder pole makes people very curious.”

The ordinary Aegis system is just a formation, with the same active and passive features. However, at the top of this formation, perpendicular to the surface, a large pole stretches out, carrying something on one side, which makes people who see it for the first time very surprised. curious.

 This involves secrets.

Kuznetsov smiled and said: "This is our unique arrangement, Qin, guess what?"

Since you asked me to guess, I'm not polite. Qin Tao pretended to think for a moment, and then said: "I think this device is for protection. Is it to protect the waveguide leading to the transmitter and receiver in the cabin?"

This thing is the front-feed horn of Lao Maozi's unique lens projection phased array system. It is unique. Qin Tao is not very clear about its specific function. After all, he is a shipbuilder. The radar used on the 051C is 30N6. There is no such big guy.

But this kind of thing only needs to be said in a few words.

Sure enough, when Qin Tao said this, Kuznetsov opened his eyes wide. Unexpectedly, Qin Tao actually said the same thing!

“Nicholas, your friend is so awesome. Is he a radar guy?”

 Having given myself so many integrated circuits, it is really amazing that I can now say what this kind of front-fed speaker means!

Nicholas smiled: “He is in business.”

“Yes, I like recycling junk.” Qin Tao said, pointing to another rusty container trailer not far away: “That junk, I think, is worth a thousand boxes of Red Star Erguotou.”

Kuznetsov looked in the direction of Qin Tao's finger, his expression changing slightly.

That thing can be exchanged for a thousand cases of wine?

 In this era, Lao Maozi's market was severely lacking in light industrial products, especially grain and fine wine.

There is no shortage of food in Novosibirsk, because it is also a grain-producing area and has a lot of grain factories, such as Beard Bread Factory, Novosibirsk Oriental Bread Factory, Karasuk Meat Processing Factory, Novosibirsk Confectionery Factory, Novosibirsk Chocolate Factory, Novosibirsk Flour Mill, etc.

 It's just that because of the nationwide food shortage, there is very little wine on the market, and the precious grain is not suitable for making wine.

Qin Tao is very generous. He first gave Kuznetsov so many integrated circuits as a gift, and now he wants to buy a piece of junk. What else does Kuznetsov have to say?

“Since Qin likes it so much, let’s give it to Qin. As for the wine…”

"Wine is a must. I will contact the country and ask them to send it over as soon as possible. Now, how about we go have a drink first?"

Qin Tao took one last look at the rusty trailer. The tires underneath were also flat, and it looked like a useless piece of junk.

Zhao Ling followed Qin Tao, but it had no effect. She just watched silently, watching Qin Tao keep fooling Lao Maozi, her eyes were full of admiration, and when she started drinking, she would become Qin Tao's life secretary can make Qin Tao drink with confidence and boldness.

 Drink, the motherland needs his stomach.

However, Qin Tao didn't drink too much. After returning to the hotel, he and Nicholas boasted for a while before returning to Zhao Ling's room.

“Brother Tao, what is that container? Is it worth a thousand boxes of Erguotou?” Zhao Ling couldn’t help but ask.

Qin Tao smiled: "If I guessed correctly, that thing should be 5N64K."

"What?"

  “64N6’s father.”

 Speaking of the S-300 system, most people only know the 64N6. This famous radar is a multiplier of the S-300 system’s combat power. This radar, codenamed Big Bird (NATO codename), provides longer-distance search capabilities. It can even monitor ballistic missiles.

Rome was not built in a day, and the 64N6 did not come out all at once. Before this radar appeared, there was another one, the 5N64 that was stuffed into a container!

If that guy is deployed, it will be similar to the current 64N6 guy, and its function is similar. In fact, it is a long-range radar prepared for the original S-300PT system, but the S-300PT system will soon reach the end of its lifespan. , this kind of long-range radar has no use, and it can be regarded as an early model test product.

 Qin Tao has already got an S-300PT system back last time. Now, if he gets this 5N64K back, he can just put it together into a system! Even if it is something that Lao Maozi eliminated, after all, it is only just ten years old.

This kind of 64N6 is absolutely not allowed to get involved. Qin Tao knows that the time has not come yet, but 5N64 is just a trivial matter.
