Chapter 301: Our technique is even more mature than that of the United States!
Early morning, two o'clock.
"The first gap, perfect!"
"The second gap, no problem, this waveguide chamber, amazing……"
"The last gap, no problem either! We did it, we finally produced a qualified flat gap radar antenna!" In his excitement, Tian Chun Guang almost dropped his caliper onto it; if it fell in, the antenna would be ruined!
"Yeah, we've been fussing for over a month, not like Qin Miao doing it in just one evening." Another classmate said: "Qin Miao, you're truly amazing! If success is ninety-nine percent perspiration plus one percent inspiration, then for you, that formula doesn't hold at all!"
Everyone was feeling emotional; even Professor Hao's look at Qin Miao seemed off.
Qin Miao had never dealt with this before, yet now, when he guided them, it was as if he had it all figured out.
Faced with all those questioning looks, Qin Miao remained calm: "Everyone, how I know this technology is confidential, so don't leak it! Also, you've all seen this machining process; it's highly confidential too. Next, we can set up a dedicated production workshop just for this antenna, but… it must stay secret, you understand?"
Now, only the United States can process this; the Soviet Union cannot, nor can Europe.
With this radar antenna produced, it's a groundbreaking invention! From now on, not only can we use it ourselves, we can also sell it, make lots and lots of money! So the technique must stay secret, cannot be leaked.
As for how Qin Miao knows this…
Simple, it's the memory of future generations.
This technology, the United States won't leak to Europe either; we can only research it ourselves!
Institute 14, which originally worked on ground radar, integrated its team to pursue this technique; a female engineer, after experimenting with many methods, finally found the correct path of salt‑bath indium welding, and in 1987 successfully produced the 1471 radar antenna.
As for fixturing, by combining vacuum and magnetic adsorption, the clamping of these high‑precision, large‑area aluminum thin‑wall parts no longer poses a problem.
Using CNC milling and chemical milling to remove cutting burrs ensures the machining accuracy of hundreds or thousands of slots and waveguide chambers.
Using salt‑bath indium welding, they successfully assembled the parts; the weld seams and deformation control were also studied in detail.
This technology far outpaces Europe! The United States is first, we are second.
However, having the radar antenna isn't enough; we also need the processing circuitry. Because domestic electronics were lagging, it took another ten years for the matching airborne radar to mature! The J‑10 uses domestically made radar, which in combat outperforms the Su‑27's radar.
Later, to improve the antenna's machining quality, many people turned this into a research topic; many master's theses at universities are on this. In his previous life, Qin Miao had read many such papers. Now, our technique is absolutely the most mature, even more mature than the United States'.
Even just the salt‑bath indium welding—its dewaxing process in the salt bath, the welding formula, and so on—were explained clearly in our theses. Of course, that's all after the twenty‑first century, by which time airborne radar antennas had shifted to active phased‑array era.
One word of confidentiality from Qin Miao scared everyone into silence; who knows, this technology might have been brought from the United States by someone on the secret front!
"San Shui, rest assured, the teachers and students of Ha Gong Da are always on edge about this! Even if people from Institute 607 come, we absolutely cannot let them see how we process it!"
Qin Miao nodded. Institute 607 is a research unit; as long as we have a qualified antenna, that's enough. The production plant might come to steal the technology, but… even if they stole it back, with their abilities they absolutely couldn't produce such high precision.
Unconsciously, Qin Miao yawned, lifted his wrist, glanced at his watch, and was instantly startled.
"Holy cow, it's already 2 a. m.! I need to hurry back to sleep!"
Ding ding ding!
Qin Miao almost jogged all the way; when he reached the family building, he saw his own room's light still on—this feeling… was truly special.
What is home? It's the harbor that keeps a light on for you no matter when you return.
Going upstairs, Qin Miao took the key, gently opened the door, pushed it in, and saw on the dinner table a dish plate, two bowls, two pairs of chopsticks……
Chu Miaomiao was still waiting for him to come home for dinner!
On the living‑room sofa, Chu Miaomiao held a book in one hand, let the other hand droop, and had already fallen asleep.
Qin Miao lightened his steps, walked back to the bedroom, took out the blanket, and gently covered his wife with it.
Watching her long eyelashes tremble, Qin Miao couldn't resist and lightly kissed her cheek.
Then…… her beautiful eyes opened.
"Brother San Shui, you're back? I… I'll heat up the food for you…"
"No need." Qin Miao shook his head: "Just go to sleep."
"I…" Chu Miaomiao hadn't finished speaking when Qin Miao already lifted her and walked toward the bedroom.
The next day, when Qin Miao opened his eyes, his wife's presence was gone from beside him, and a scent of food drifted from the kitchen.
He walked into the kitchen, saw the busy Chu Miaomiao, and felt only a fullness of happiness.
So he walked around behind her, gently embraced his wife, and said, "Miaomiao, you've worked hard; actually, just getting a meal from the cafeteria would be fine."
"It's already 10 o'clock; the cafeteria has no food left, but it's okay—there's no exam this morning, so go wash up, brush your teeth; breakfast? No, lunch will be ready soon."
After lunch, Qin Miao and Chu Miaomiao went downstairs together; he got into a Range Rover and headed straight for the Ha Gong Da Microelectronics Company.
Fighter jet flight control and radar need chips; teachers and students doing R&D also need a microcomputer assembled from general‑purpose chips, and they could even string multiple chips together to make a supercomputer—who knows how the Loongson development is going?
The company's main building is a seven‑story tower that was completed long ago; stepping inside, Qin Miao also felt a myriad of emotions—last time he had brought Engineer Ni along to persuade the other chip experts at the Chinese Academy of Sciences Institute of Computing, coordinating the production equipment, and after that… he hadn't given it another thought.
Now, I really feel a bit embarrassed… but the building is empty—where is everyone? Could it be that today is a weekend off?
"Comrade Qin Miao? You've finally shown up! You came specially because you heard that Loongson No. 1 has started wafer fabrication, right?"
"What? Wafer fabrication? That means Loongson No. 1 is already out! This is a huge gain!"
Qin Miao took off running toward the factory building behind the complex.
