Military Industry of Great Powers: Build the Strongest Flanker

The drawings on Zhao Guoqing's drawing board are densely filled with circuit diagrams.

Chief Engineer Bi walked closer and was shocked to find that the drawings on the paper were not the ones distributed, but were drawn by Zhao Guoqing himself.

Looking at the densely packed integrated circuits above, they are divided into large and small frames, and the blank spaces of each frame are also marked.

Although the drawings are complicated, once these frames and labels are added, they immediately become simple and clear. The functions of this circuit are noted on them, such as filtering, amplification, resonant waves...

Engineer Bi looked more and more surprised next to Zhao Guoqing. At this time, Zhao Guoqing was still focusing on drawing, even though he knew that there were two more people around him.

"This is a brand new filter circuit!"

Engineer Bi could see it at a glance. Of course, KBJJ_4B (modified) was written in the lower right corner of the drawing. What surprised Engineer Bi was that he couldn't understand some of the circuits.

The so-called meter-wave radar is a radar that emits radar waves with a wavelength of one meter to ten meters. This type of radar wave has strong penetration and strong detection ability, but its shortcomings are also obvious, that is, the detection range is short (cannot propagate in the atmosphere) , the accuracy is poor (the technology cannot reach it at this time). The viewing angle is small.

Since the viewing angle is small, Mao Xiong directly sets the detection angle to 15 degrees up and down, and naturally cannot detect high altitudes or low altitudes.

In addition, radar emits electromagnetic waves, which echo not only aircraft, but also many obstacles on the ground.

How to remove these interferences is also a problem. Lao Maozi directly uses redundant wave removal, only detects moving objects, and directly removes the same waves in two scans. This is a broad idea, but the problem is not small.

And Zhao Guoqing's miraculous circuit appropriately makes up for this.

Chief Engineer Bi lamented Zhao Guoqing's ability, but no matter how much he repaired the old antique, it would be of little use.

"This meter-wave radar was introduced to Mao Xiong in the 1950s, and its performance is now insufficient."

Compared with X-wave radar (short-wave radar) and S-wave radar (long-wave radar) in this era, meter-wave radar has no obvious performance advantages and major flaws, but it will be different twenty years later.

The unique anti-stealth capability of meter-wave radar has given designers of stealth aircraft a headache. It is known as the F22 killer. After adding the phased array, the accuracy is greatly increased. It can guide surface-to-air and air-to-air missiles within a range of 150 kilometers. , which is the restricted area for stealth fighters.

When Zhao Guoqing heard what Mr. Bi said, he put down the pencil in his hand and turned around.

"Director Liu, why are you here? This is..."

"It's Mr. Bi!"

"Hello, Chief Engineer Bi, I am Zhao Guoqing!"

"National Day, not bad, can you tell me what you drew?"

Zhao Guoqing confidently led Engineer Bi to the drawings, pointed at the drawings and said: "The circuit to remove radar clutter, I always feel something is wrong when looking at Mao Xiong's drawings! After thinking about it, I decided to draw it myself... "

"..."

"Then what's going on with all your frames and annotations?"

Zhao Guoqing laughed and said: "The drawings of Mao Xiong are so messy and I am so tired from looking at them!"

"..."

General Engineer Bi burst into laughter. Zhao Guoqing was absolutely right. Most of the experts who came from that era started their research by reversing the Bear's equipment.

Reverse engineering is not simply copying or imitating, but in the process of imitating, you need to understand why someone designed it the way they did. And Mao Xiong’s drawings often cause this problem, that is, they are too difficult to understand...

"What a great idea. This way, it will be much easier for everyone to look at the drawings. If there is a problem, it will be easy to find out!"

Zhao Guoqing looked around. A group of new students who had just entered also looked at Zhao Guoqing with admiration.

The structured design with annotations is also very friendly to newcomers. Some of these newcomers who came in together have not been able to understand even a single drawing in half a month.

For example, if you are given a set of engine drawings, a newcomer will definitely be confused, but if the engine is divided into oil circuit, air intake, combustion, injection, cooling, electronic control... and other parts, then a system diagram can be used to synthesize the various parts. The role of partial operation, this thing is much simpler.

Yingjiang’s set of design ideas still has merit.

"Okay! Okay!" General Engineer Bi said to Zhao Guoqing: "This method is very good. I think it can be promoted..."

"I was just messing around!"

"There's no fooling around, it's of great significance."

Engineer Bi looked at Zhao Guoqing and became more and more emotional. It was rare among the 14th institute's newcomers to be able to design the circuit like this. It is true that the waves behind the Yangtze River push the waves ahead, but this is only excellent, not amazing. When he saw Zhao Guoqing's next drawing, Engineer Bi stopped talking.

Director Liu on the side looked at the Magic City watch on his wrist and touched Chief Engineer Bi.

"Lao Bi, Institute 53 came to our place for a seminar at 2:30 today. It's almost too late."

I originally thought it would only take a few minutes, but half an hour has passed since I arrived here, and Mr. Bi has no intention of leaving yet.

"Lao Bi, Lao Bi!"

General Engineer Bi patted Director Liu's hand impatiently, "You go first, I'll be there later!"

"..."

The second drawing is for private goods, that is, logic circuits, bipolar, unipolar TTC, LEC, various types of AND or gates, and NOT gate logic circuits, there are more than twenty types in total, and they are Mark each one with a symbol.

These gate circuits are composed of ordinary diodes, transistors, capacitors, and resistors.

In the drawing below, these logic gate circuits are directly quoted. On the huge drawing, various logic gate circuits are densely covered with stars, and thousands of components are organized together in an orderly manner, just like the previous circuit diagram.

The entire drawing is also divided into various frames, and each frame is labeled.

In fact, in this era, the country has made great achievements in electronic computers, and has even made a large computer.

What surprised Mr. Bi was that he was only familiar with 13 of the 26 gate circuits, especially the bipolar ones, but he didn't know any.

However, relying on a solid circuit foundation and Zhao Guoqing's detailed drawings and descriptions of these gate circuits, Mr. Bi can still understand the working principles of these gate circuits.

Chief Engineer Bi looked at Zhao Guoqing, his eyes filled with wonder, doubt, and disbelief.

He felt that the young man in front of him might have a deeper knowledge of integrated circuits than he imagined.

How can it be?

When he saw the circuit diagram below, Mr. Bi was dumbfounded.

"Did you draw all this?"

"How do you know about logic gates? Have you ever studied logic gate circuits?"

Zhao Guoqing nodded and said: "The school has the latest foreign electronic publications, which introduce these logic gate circuits."

"..."

"You figured it out based on these publications?"

Zhao Guoqing nodded and said: "Absolutely!"

"..."

Mr. Bi's brain is a bit exhausted.
