Back in 1978, I was admitted to Northwestern Polytechnical University.

Chapter 115: One Flat Panel Antenna for Eighteen Projects?
"Qin Liang, what do you suggest?" At this moment, Qin Liang's three friends in the laboratory had their eyes shining.

"Zhao Xiaoxia, you've carved paper-cut window decorations at home, haven't you?"

"Ah."

"You take the carving knife and carve the filler material!"

What? Zhao Xiaoxia was stunned. This radar was made using carving techniques?
Qin Liang smiled. In later generations, there were descriptions of this in the "Great Craftsmen of the East" program. The engraving of the brazing needle must be done in one go, without any finishing touches, otherwise the antenna will be substandard! Not even a single tool mark can be left.

Zhao Xiaoxia was a woman. When Qin Liang met her in his later years, he heard that she had been carving paper-cuts since she was a child and that her hands were very steady, so he had full confidence in her.

"Yang Wei, you've really mastered computer programming these past few days, haven't you?"

"Ah."

"To write the CNC program, we need to use a CNC machine tool to cut aluminum foil."

"CNC programming? I don't know how to do that!"

"Take a look at the instructions, it'll be quick, I trust you!"

"it is good."

Tang Changhong looked at Qin Liang: "What am I going to do?"

"Let's make a special clamp together!"

Planar slotted radar antennas have been a major obstacle to the advancement of China Eastern's aviation technology. Many engineers have worked tirelessly to overcome various technical difficulties in researching this technology. Zhang Zongyue, a senior engineer from the 14th Research Institute, made outstanding contributions!

She proposed a clamping method combining high-precision vacuum adsorption and magnetic attraction, solving the clamping problem of high-precision, large-area thin-walled aluminum parts; using new technologies such as CNC machining and chemical milling to remove cutting burrs, the machining accuracy of hundreds of cracks, grooves and waveguide cavities met the specified requirements; using the pin joint assembly process, the quality of brazing seams and welding deformation were well controlled, and finally, the radar antenna of 1471 was manufactured in 1987!
These technologies were declassified long ago, and there are even various papers discussing their improvement. Now, Qin Liang is bringing out the earliest, immature technology to show the West how advanced our Eastern technology is!
Everyone got busy.

外面，屠老等人也在和英国人继续谈判，商讨各种引进设备，956型平视显示器、250-408-02型大气数据计算机、AD3400多频段通讯电台、AA3460保密机、0101-HRA/2型雷达高度表……

Time flew by during the negotiations—one day, two days, three days…

That afternoon, everyone's attention was clearly elsewhere during the negotiations. The clock on the wall ticked away: three o'clock, four o'clock, five o'clock...

"Why is there still no movement from the lab?" Janice said. "Could they be struggling with how to glue the radar antenna back together?"

"Yeah, she might be crying right now because things might not go well!"

“No, we have to go check on them! If they’re crying, we have to comfort them!” Janice stood up and strode outside.

"Old Tu, we..." the Easterner said anxiously.

"Trust Qin Liang. If he says three days, then it's three days. Let's go and take a look!"

Laboratory entrance.

dong dong!

dong dong!

There was no response from inside!
“Use the key to open the door!” Peterman said.

With a clatter, the lock opened, and the heavy security door was pulled open. The first thing everyone heard was... a shout coming from inside.

huh, huh, huh...

The Easterners are sleeping? Janice was secretly delighted. What a load of rubbish! They really didn't succeed and gave up immediately! They just fell asleep. What advanced technology could Easterners possibly have that we British can't do…

and many more!

On the test bench, there is a large disc with a diameter of 800 millimeters. It is yellow all over and has slits on it that form beautiful patterns under the light. Is this already made?

Hmph, even if it's made, it might not be a mature product. After all, we've made many, but they're all defective, none of them usable...

Hey, there are a few printed papers next to it. These are... machine-printed reports from the testing equipment in the lab. These reports can't be faked!
Diameter: 800 millimeters.

Number of waveguide slots: 783.
Machining accuracy: all less than 0.02 mm.

Antenna power-on test results...

All of them are qualified!

“This, this is impossible!” Janice exclaimed.

His voice startled the person sleeping nearby.

"Hey, stop! Don't touch our antenna! You can't afford to pay for it if you break it! Hey, you're not doing this on purpose, are you?"

Janice quickly took two steps back: "Of course not, I just..."

"Just what? If you want to test it, then test it again under our supervision. If you want to install it on an aircraft for testing, then go ahead and install it on the aircraft for testing. Be careful not to touch the antenna surface..."

After saying that, Qin Liang yawned, lay back down, and took another nap!

Under the supervision of the Easterners, a group of British people carefully conducted the test.

Machining accuracy: Qualified; Antenna performance: Excellent!

"Impossible, impossible, how could you Easterners possibly manufacture such a sophisticated antenna? This..." At this moment, all that was left for Janice to say was this.

Having taken a nap, Qin Liang is now full of energy.

"This thing wasn't made by us, so how could it be conjured by magic? I've already said, just because you can't make it doesn't mean others can't."

“Yes, your Eastern technology is truly impressive!” Peterman said. “We greatly admire your technology! Mr. Qin, would you be willing to sell us this technology? We are willing to pay any price!”

Qin Liang glanced at Elder Tu: "Elder Tu, has the deal been finalized for the introduction of Super 7?"

"Yes, we plan to introduce a total of eighteen projects, comprising more than three thousand subsystems..."

"Mr. Peterman, how about we stick to what we agreed on before: technology for technology?"

“This…” Peterman took a deep breath: “I have already reported to the company, and the company’s opinion is that you need to purchase one hundred sets of equipment before we will consider technology transfer.”

"Oh, then you should purchase one hundred sets of these radar antennas from the East first, and then we can discuss technology transfer."

The UK only wants to produce about a hundred Tornado air defense aircraft. If they buy a hundred sets first, they won't need to produce any more themselves; that will be enough!
"Mr. Qin, technology exchange is not out of the question. We can exchange one project for another. Of the eighteen projects you have introduced, you can choose one project to exchange. How about that?"

Old Tu's expression changed slightly. Oh no, he had said the wrong thing and caused trouble for Qin Liang! Why did he say so much?
“No way! Our processing technology alone is worth eighteen of your projects!” Qin Liang shook his head: “If you’re going to change, change them all at once. If not… General Sabil, let’s go to France next and look for Thomson Company. I think they would be interested in our technology.”

"Wait!" Peterman quickly interjected, "Mr. Qin, please stay in England and wait for us for another day. You've come to England, but haven't gone shopping yet, have you? You can go out and look around tomorrow, and buy whatever you like. Our Marconi Company will pay for it!"
