Genius is just the threshold for me!

"The temperature control precision is insufficient..."

Lin Dong's expression shifted, as if he had thought of something: "Have you ever tried laser treatment?"

"Laser?"

Xu Ziming paused for a moment, then subconsciously said, "The current solution is electromagnetic temperature control, but laser... I haven't tested that."

However, after reviewing historical research materials, I found that about six years ago, someone in the materials science lab at Beihang University attempted a laser-based solution, but it ultimately failed.

The dd9 materials laboratory has been around for almost ten years, but it has not been able to make a breakthrough in macroscopic mass production. It's not that no one has been researching it during these ten years; many people have participated in the effort to achieve mass production of this material, but all of them have ultimately failed.

"Uncle Xu, six years ago, the laser technology in China was rubbish, but now it's number one, and that number one technology is right here at Chengdu Aircraft Industry Group."

Lin Dong reminded him, "If it's just a matter of temperature control accuracy, I think my dad can solve it."

All you need to do is measure the precise spectral absorbance of DD9 material, then use elementary multiplication to calculate the laser power required to maintain this temperature, and then irradiate it with several stable lasers… As long as the laser is stable enough, the temperature will be stable enough.”

"Use laser irradiation to control the temperature..."

Xu Ziming was taken aback for a moment, then subconsciously said, "Didn't you come?"

"This stability and power..."

Lin Dong picked up a few documents from the table, found the temperature fluctuation rate on one of them, and shook his head: "My dad is enough."

"..."

Xu Ziming was disgusted by Lin Dong's pretentious behavior in front of him, but after thinking about it carefully, he felt that Lin Dong's words made sense.

Compared to electromagnetic temperature control solutions, because magnetic fields are inherently fluctuating, it becomes extremely difficult to achieve a certain level of precision.

Lasers manufactured based on the principle of stimulated emission naturally possess unique stability and energy concentration.

If the laser power can meet the requirements and the excitation stability of the light source is good enough, then it is possible to achieve the precision standard of temperature control for third-generation single-crystal nickel-based materials.

Having determined that the plan was likely feasible, Xu Ziming did not hesitate and immediately took out his secure phone to inquire about the arrangements.

In less than half an hour, the laboratory below measured a precise spectral absorbance.

Based on this absorption rate, Xu Ziming calculated the required laser power and the temperature control stability coefficient, and then contacted Lin Weiliang by phone.

After briefly reporting the parameters and receiving a positive reply, his previously somber expression immediately brightened with joy.

"It's safe!"

Xu Ziming couldn't help but cheer, looking at Lin Dong with delight, he said, "According to the laser power, accuracy, and control reaction time parameters that your father provided..."

This laser can be used not only for crystal temperature control, but also for precise control of melt overheating, helping to reduce impurities and impurities, and also reducing disturbances to the magnetic and electric fields of electromagnetic devices.

All these factors combined can raise the pass rate to at least 80%, making the DD9 material completely secure!

"That amazing?"

Wang Xingguo, listening nearby, exclaimed incredulously, "Over 80% all of a sudden?"

Before Lin Dong arrived, they were still sighing and complaining, with a pass rate of less than one in a thousand.

Lin Dong just mentioned laser temperature control to you, and you're already telling me the pass rate is over 80%... Even magic wouldn't be that exaggerated.

"The mass production route for third-generation single-crystal materials has been successfully established, with the main bottleneck being the lack of temperature control precision. The material is only going up, not down.

But Engineer Lin's laser technology solved this problem at its root...

Xu Ziming took a breath and nodded seriously: "Let me do a simple estimate. If we optimize all aspects of the entire process, the pass rate can be stabilized at over 95%."

The only drawback is that laser-based production consumes a lot of energy, potentially requiring the construction of a dedicated power plant. Furthermore, it's only suitable for producing DD9; for DD33, it would actually increase costs…

However, as long as we can produce the DD9, our J-20 can finally have a new engine.

As he spoke, Xu Ziming's voice trembled slightly, and a glint of light appeared in the corner of his eye as he became emotional.

The J-20 fighter jet is Chengdu Aircraft Industry Group's pride, but also its regret.

After graduating, he and Lin Weiliang and others passed the security audit and began to join the J-20 peripheral project.

He was also able to enter the core project of the J-20 fighter jet in less than three years due to his talent. During those years, even with his lazy personality, he was working overtime like crazy.

It can be said that the J-20's journey from its inception in 01 to its successful maiden flight, spanning 11 years, is a testament to his ten years of youth after graduation...

But I didn't expect it.

They spent ten years of their youth, risking their lives to develop the fighter jet.

However, the 624 and 606 projects have encountered a huge problem: the Emei WS-15 turbofan engine, for which they haven't even produced a formal design.

Ultimately, the J-20, which took ten years to develop, could only be equipped with the engine of the J-10.

Born with a severe heart condition, they had to take to the skies, a regret for all of their generation of sprinters.

He originally thought that the engine project had been stalled for at least five years, or even ten.

Unexpectedly, in just the second year, we have already seen a glimmer of hope amidst our regrets.

Breakthroughs have been achieved in engine materials, and the engine design has found the right direction, beginning rapid progress...

"good!"

"Now that we have the materials, the next step is to urge that old man Jiao You!"

Wang Xingguo also looked very happy.

But suddenly, as if he had thought of something, seeing Xu Ziming's excited expression, he quietly pulled Lin Dong aside.

"Your Uncle Xu is in a good mood today. Why don't you strike while the iron is hot tonight, take a list over, and give him a piece of your mind... maybe give him a prestigious academic achievement to make things even better?"

No!

Lin Dong's expression froze. He looked at Wang Xingguo and lowered his voice, saying, "You kept this materials project a secret from him. You said it was some kind of Emei project assistance project, and that you finally managed to snatch it from Beihang University, so if anyone was going, you should go..."

"Then let's go together."

Wang Xingguo decisively replied, "I can't write this list myself..."

"I can give you the list, you can pass it on," Lin Dong said without hesitation.

"To be honest, I'm not afraid of business matters, but when it comes to personal matters... I'm afraid Engineer Xu will beat me up. He's armed with a wrench and hammer, unlike your dad."

Wang Xingguo readily admitted defeat, saying, "But with you juniors around, he felt embarrassed to make a move..."

"Godfather".

Lin Dong was truly impressed and gave him a thumbs up, saying, "You're really ruthless..."

"What can I do? You know Xu's personality."

Wang Xingguo shrugged, showing no embarrassment whatsoever, and said, "He already disliked you, so when he heard he had to take orders from you and do the work, he just gave up immediately..."

However, Chengdu Aircraft Industry Group (CAC) could not find another employee with a strong foundation in materials science who could also meet the confidentiality requirements.

Only Engineer Xu, whom you've known about your situation since childhood, is your elder, and holds dual doctorates in materials science and engineering.

"..."

Looking at Wang Xingguo's answer, Lin Dong couldn't help but silently mourn for the employees of Chengdu Aircraft Industry Group for half a second.

Having a 001 like that makes it hard for anyone to even want to be a nobody.

When he makes arrangements, he at least tries to persuade people with reason. If there's anything you don't understand, he'll write down the paper number for you.

But Wang Xingguo's style of arranging things is so subtle that he can sell you out and still count the money...
