Chapter 146 Assisting in Solving the J-15 Carrier-based Aircraft Project

It's 6:30 p.m.

Lin Dong spent an hour optimizing and modifying all the control code of the mechanical dog system, and then sent a revised design drawing to Xu Ziming via confidential email on the intranet.

Uncle Xu, could you make a mechanical pet for Qingling using the best PEEK material, and make it look nice? How long would that take?

Ring ring—

The drawings were sent out in less than a minute.

At that moment, the secure cell phone next to me rang.

Lin Dong took the phone, glanced at it, and answered the call: "Uncle Xu, what's wrong?"

"Are you really going to make this mechanical dog?"

The sound of a mouse moving came from the other end of the phone. Xu Ziming looked at the blueprints for a while: "35 kilograms of weight, isn't the motor power too high? If it goes out of control, it will be like a mad dog running rampant. Is it safe for Qingling?"

And this speed limit... 90 kilometers per hour? Can a dog run that fast?

"We have implemented a contingency plan. The program verification shows that there will be no problem with loss of control. If there is a hardware problem, there is a second redundant design to lock it in place when the power is off."

Lin Dong explained simply, "As for speed, real hunting dogs can run at speeds of 60 kilometers per hour, but this is for collecting training data for combat mechanical dogs. If the speed is too low, it won't be effective."

Running at low speed and running at high speed are two different types of data.

Since the goal is to collect training data for combat mechanical dogs, it's impossible to only involve low-speed training.

According to Lin Dong's plan, low-speed mobility will be handled by the users.

We'll conduct high-speed testing, and my uncle will arrange for people to test it in various environments, or we'll open the feature to users who like to "walk their electric dogs".

As for security.

The entire security setup is at the lowest level and has the highest priority.

Once the infrared sensor detects an infrared heat source and the image identifies a human figure in front, the system will automatically limit the power and speed of the robotic dog.

According to Lin Dong's calculations, this safety design can guarantee zero accidents.

The reason why it cannot be absolutely guaranteed is to avoid some coincidences or some bizarre things deliberately created.

However, the robot dog's camera can automatically record the situation, preventing staged accidents.

"...You used the data from Song Qingling's pet mechanical dog to train combat mechanical dogs?"

Xu Ziming paused for a moment, as if he wanted to say something, but in the end he held back: "As long as there are no safety issues, that's fine."

The number of parts is small, the confidentiality requirements are not high, and the precision and process requirements are not high, so most of them can be arranged for production.

"Once it's finished tomorrow, I'll put it directly in your lab. You can assemble it yourself after school and give it to Qingling."

Done.

Xu Ziming hung up the phone before Lin Dong could reply.

"..."

Hearing the phone call end, Lin Dong couldn't help but complain, "Uncle Xu really is a doting father. He always drags his feet when I ask him for help, but now that he says he can finish it for Qingling by tomorrow..."

After making a couple of sarcastic remarks, Lin Dong ignored Xu Ziming's efforts, turned off the lab screen, picked up his backpack, looked at the sunset outside the window, and stretched: "Great, I've done another small project today."

Ring ring—

Lin Dong was about to go home when suddenly, his secure cell phone rang again.

Ok?

Is Uncle Xu busy again?

Lin Dong picked up the phone and looked at it. He realized it wasn't Xu Ziming calling, but Comrade Lin Weiliang. He immediately answered, "Dad, what's wrong?"

Are you in the lab?

Lin Weiliang spoke quickly and directly: "If you're here, I'll send you an internal network link to join a confidential online meeting."

"A confidential online meeting?"

Lin Dong paused for a moment: "With other people?"

"On your godfather's side, there's no one else."

Lin Weiliang explained, "But you shouldn't turn on the camera either."

"it is good."

Lin Dong had no objection to the decision.

Although he knew that all confidential meetings and emails used military communication networks, which were physically disconnected from civilian networks, and were encrypted using multiple encryption algorithms.

However, military communication networks are not absolutely secure; otherwise, there would be regulations that require time control for long-distance secure calls and prohibit calls from lasting for extended periods.

Lin Dong hung up the phone, and a short while later, Lin Weiliang sent him a link and a 48-digit verification code via email.

Lin Dong turned off the camera, clicked the link, and then entered the verification code.

Di-

The entire screen changed instantly.

The images of Wang Xingguo, Xu Ziming, and Lin Weiliang appeared above, with Lin Dong's own black image showing his camera off.

"There's something I need to say."

When Wang Xingguo saw Lin Dong come in, he calmly began to talk about the meeting: "The medical examination results of the core team at Shenyang Aircraft Corporation working on the J-15 carrier-based aircraft are out."

One person is required to take six months of mandatory rest, another is required to take two years of mandatory rest and also needs surgery, and both are required to take three months of mandatory rest.

There are three people left. The doctor at Shenyang General Hospital said their bodies are already overloaded and suggested they also temporarily stop working and rest for half a month before returning to work...

"hiss--"

Xu Ziming took a breath: "Is it that serious?"

"Is Shenyang Aircraft Corporation's chief engineer going to have surgery?" Lin Weiliang seemed to have thought of something.

"Yes, his coronary arteries are nearly 90% narrowed, and the doctor said he could have a myocardial infarction at any time... Moreover, this old guy's heart is not very sensitive."

The doctor said that a normal 75% narrowing of the heart muscle would result in insufficient blood supply, which would cause noticeable symptoms, but this old man said he felt nothing at all.

I don't know if he really didn't feel anything, or if he just didn't have time to feel anything, but he's already in the operating room tonight.

Before the surgery, he talked to me about the project. Now he's in the ICU after the surgery, but he definitely won't be able to work for at least two years.

Wang Xingguo gave a brief introduction to Yuan Li's situation.

His tone was calm and steady, but Lin Dong, Lin Weiliang, and Xu Ziming could all hear the suppressed emotions in it.

"There is a problem now: the core of Shenyang Aircraft Corporation's carrier-based aircraft project can be said to be temporarily paralyzed."

Wang Xingguo took a deep breath and controlled his emotions: "But the Varyag is now internally confirmed as the Liaoning, our country's first aircraft carrier, which will be delivered on the 25th of this month. All that's left is to get the carrier-based aircraft ready..."

"What headquarters means... is for Chengdu Aircraft Industry Group to take over urgently?"

Xu Ziming guessed what was going on and frowned slightly: "We have similar solutions for the structure and protection of carrier-based aircraft that we can directly modify and apply. We can complete it in about a month."

However, the FADEC system responded that this problem could not be solved.

The fighter jets we study all take off and land at land-based airfields. The response of the FADEC system is at least several levels lower than the response requirements for aircraft carrier takeoff and landing.

If this were implemented, carrier-based aircraft would be deployed at breakneck speed; if one aircraft mislanded, it would crash into the sea.

As one of the core engineers and department heads of Chengdu Aircraft Industry Group (CAC), although he was in charge of the manufacturing and assembly department, he did not participate in the overall design of the fighter jet.

However, Xu Ziming still has a very clear understanding of the various systems and hardware involved in fighter jets.

"You don't need to take over everything."

Wang Xingguo shook his head: "Before Yuan Li went into the operating room, he told me that their Shenyang Aircraft Corporation's J-15 carrier-based aircraft project plan was completely fine."

He repeatedly tested the fighter jet's airframe structure and protection, and the response of the FADEC system hardware was up to standard. Now, only the FADEC system's software optimization was insufficient...

Now it's up to us to assist in optimizing this FADEC system.

There were a few minor details left; they would be assigned to those three who were ready to work in a week.

"System optimization..."

Xu Ziming read it aloud, then looked at the camera without saying anything.

But everyone present knew that if Xu Ziming were there at that moment, he would definitely be looking in Lin Dong's direction.

In the eyes of Jiao You and several core leaders, Lin Dong was a super prodigy, the hope of the future, and the technical demolition expert of Unlimited Firepower.

This kid solved a technical problem that no one else could solve in a flash.

But only a few of the elders who had been in close contact with him understood that Lin Dong's most extreme area was not technical breakthroughs, but system optimization.

He can spot the flaws in anything involving systems or algorithms at a glance.

He can tell at a glance how to adjust anything related to optimization and debugging, whether it's software or hardware, to achieve a perfect balance.

From developing a laser interception system to swat mosquitoes, to developing the flight control system for the Hot Hot drone, the intelligent air combat system for the Hot Hot drone, and the swarm system for multi-rotor drones, etc.

Each of these requires a great deal of effort to develop the algorithm, and then a large number of people to spend several years repeatedly writing and modifying the code.

This thing works just like writing numbers one, two, three, four, five. It can chat with you while you write, and in the end it runs perfectly without any modifications, without a single bug or flaw.

How much work is required for a system with tens of thousands, hundreds of thousands, millions, or even tens of millions of lines of code?

For keyboard input speeds without lag or modifications, this would take at least one or two days, and at most one or two months.

Even more outrageous is that they have completed the initial accumulation work.

Now this guy no longer writes from scratch, but simply copies and pastes the functional modules he wrote before, and then readjusts and optimizes them...

"this……"

Looking at the silent meeting room, Lin Dong scratched the back of his head, realizing what the elders were thinking, and then said something a little embarrassed.

"My achievements are the result of my studies. Without studying, my level would be just so-so. You can't ignore the hard work I put in behind the scenes just because I'm good at it."

"You call that studying hard?"

Lin Weiliang didn't call Lin Dong by name: "What you're doing is called scanning; even the automatic college entrance exam grading machine isn't as fast as you..."

"That's still learning, it's just that my learning efficiency is a little different from yours."

Lin Dong said with a smile, "Look, I even spent an hour today making a system for a mechanical dog."

"...Mechanical dog? You guys chat, I'm going back to eat."

Lin Weiliang exclaimed in surprise, and the next second he slammed his foot out of the conference room.

"Cough cough..."

Seeing the atmosphere in the meeting room change suddenly, Wang Xingguo felt a little more relaxed, as the suppressed emotions he had been feeling because of Shen Fei's situation eased. He coughed twice and said...

"I'll go back tomorrow and bring back the FADEC system data for the J-15 carrier-based aircraft. Could you take a look at it for me then?"

"Okay, but don't miss their test data. I can't optimize without data."

Lin Dong nodded.

Since Shenyang Aircraft Corporation's core team was paralyzed, he did not refuse the matter concerning the first carrier-based aircraft in China.

"Oh, right!"

After saying that, Lin Dong seemed to think of something else, and again did not call Wang Xingguo by name: "It would be best to bring back the design drawings of their FADEC system hardware solution as well, so I can see if there is anything I can improve on the way."

When you get back, hold another meeting on the WZ-8 project. The final verification phase of this project is about to begin.

After the meeting, go to Xi'an and urge the Xi'an Institute of Optics and Fine Mechanics to confirm the exact delivery time of the reconnaissance instrument.

This time, even though the CETC 607 team came to urge us, they still couldn't give us a definite time, which is seriously delaying the project's progress planning..."

"Um... that old guy Yuan Li is awake. I'll go check on him, we'll talk when we get back!"

Upon hearing this, Wang Xingguo, as if encountering some great terror, hurriedly closed the online meeting room before Lin Dong could finish speaking.
