Genius is just the threshold for me!

"it is good."

Xia Ran smiled and nodded, then walked to the living room and sat down next to her parents.

Lin Dong poured a cup of tea for everyone, but instead of joining the adults' conversation, he sat down at the dining table and started playing on his phone.

Seeing this, Xu Qingling quietly walked over, and the two whispered to each other.

He Ying noticed Lin Dong and Xu Qingling whispering to each other, and glanced at the four parents who looked completely at ease and showed no reaction.

She glanced again at her daughter sitting next to her, holding a teacup with a calm expression, but her eyelashes could be seen fluttering gently in the living room light.

"Forest worker."

After Xia Tianqiang and Lin Weiliang exchanged a few pleasantries and started talking about job transfers, He Ying also stopped paying attention to her daughter, took out the job transfer application form, and continued the conversation.

"I've been working in core R&D at Xi'an Aircraft Industry Group for many years, and my health and energy have suffered as a result. I've been with Chengdu Aircraft Industry Group for a while now and would like to request a transfer from my core position..."

"Which department does Engineer He want to be transferred to?" Lin Weiliang nodded and did not refuse.

"The logistics department or the flight test department are both fine. I'll follow the organization's arrangements," He Ying said earnestly.

"Since it's a health issue, then let's go to the logistics department. Their working hours are relatively stable. The flight test department sometimes has missions that require shift work."

Looking at He Ying's rosy complexion and then at Xia Ran sitting next to her, Lin Weiliang roughly understood why she was being transferred.

Remembering Lin Dong's words about taking care of both the big family and the small family, he didn't stop him. He took out a pen, wrote "Logistics Department" on the job transfer form, and then signed his name.

The pen tip glides across the paper, making a soft, crisp scratching sound.

A few seconds later, Lin Weiliang handed the signed job transfer form back to He Ying, and said with a smile, "Engineer He, you can just ask Chief Engineer Wang to sign it tomorrow. If needed, I can put in a good word for you."

"Thank you, Engineer Lin."

He Ying breathed a sigh of relief, exchanged a glance with Xia Tianqiang, and after a brief chat, got up to say goodbye.

"Lingling, your dad and I are going out for a walk. We'll come back to pick you up later?" Zhou Xiaoyan asked with a smile, looking at Lin Dong and Xu Qingling at the dining table.

"I'll go home by myself later, you don't need to come pick me up."

Xu Qingling immediately replied, then waved to Xia Ran and said, "Xia Ran, see you tomorrow."

Xia Ran waved to Lin Dong, then went back with Xia Tianqiang.

I watched Xia Ran's family, including her parents, leave.

Seeing Zhang Xiali close the door, Xu Qingling seemed to remember something and leaned closer to Lin Dong, saying, "Have you noticed that Xia Ran has changed a lot lately?"

"Isn't change normal?"

Lin Dong smiled and said, "The problem of parents is the root of all children's problems. She used to support herself alone, but now her parents are supporting her."

Not only Xu Qingling, but Huang Qingyao and the others also noticed Xia Ran's changes.

He used to be proud and sharp, but there was always a sense of stubbornness and repression in him.

Now she's less proud, more cheerful, and talks more.

But before Xu Qingling could answer.

Lin Weiliang, who had just seen the person off, returned and, upon hearing this, immediately turned around and pointed to his graying temples: "Parents' problems are the root of all children's problems..."

Son, are you sure that in our family, this shouldn't be said the other way around?

"puff--"

Xu Qingling couldn't help but laugh.

"Alright, you're almost forty years old, why are you still getting angry with your kids every day?"

Seeing this, Zhang Xiali nudged Lin Weiliang and urged, "Hurry up and change your clothes. We'll take Qingling home later. Xiaodong is busy."

"You've spoiled our son," Lin Weiliang protested, but didn't say anything more before going into his room to change.

After waiting for a while, Lin Dong received a message from Wang Xingguo. Without lingering, he told Xu Qingling and took his phone into the study.

Ding-dong! Ding-dong—

After turning on the computer and connecting to the intranet, Wang Xingguo's email account was immediately alerted with a new email notification.

[Chief Engineer Chen from CETC (Institute 607)]: Hello, Engineer Wang. This morning I personally verified the calculations. The weight of the active phased array (AESA) radar with 2400 gallium nitride TR module units meets the requirements of the Chengdu Aircraft Industry Group's (CAC) solution, but the radar size will be 28.3% larger...

"The size is 28.3% larger... Has CETC not fully mastered gallium nitride AESA radar technology yet?"

Lin Dong frowned as soon as he saw the first email.

The J-16 was modified into the J-16D because it needed to be equipped with a series of electronic warfare equipment, regardless of whether it was Shenyang Aircraft Corporation's plan or Lin Dong's plan.

The original cannon system and infrared search and track system (IRST) equipment of the J-16 fighter jet will be removed to make room for the installation of electronic warfare equipment.

According to Lin Dong's calculations, removing these machine gun and IRST equipment would be enough to fit a complete electronic warfare system.

But now, one of the AESA radars from China Electronics Technology Group Corporation (CETC) exceeds the size limit by 28.3%, which is a real problem.

The space he painstakingly freed up by dismantling the machine gun and IRST equipment wasn't even enough for this one radar that exceeded its limits.

"Put that aside for now, and deal with the problems that can be handled..."

Lin Dong thought for a moment but couldn't think of a way other than grabbing business, so he marked the email and started replying to and processing other emails.

Since it's just an improvement project and doesn't require designing the entire fighter jet, most of the tasks arranged yesterday were related to improving data collection, which requires a lot of actual testing and will take a long time.

Of the more than thirty emails sent, only half were replied to within a day; Lin Dong finished processing them in less than an hour.

soon.

There were two unprocessed emails left in my inbox: one was a reply from the electronics company, and the other was also related to the electronics company.

[Chengfei Engineer Wei]: Engineer Wang, I confirmed with Shenyang Aircraft Corporation this morning that the fully functional giant darkroom for the entire J-16 fighter jet is still under renovation and construction.

The anechoic chamber management department of the electronics company is also reporting a severe shortage of microwave anechoic chambers. There is only one large anechoic chamber that can meet the testing requirements of your equipment layout diagram.

I applied for an anechoic chamber test, but the management department said that the company has a bunch of new radars that need anechoic chamber research and development, and this large anechoic chamber will probably not be available for us to conduct the test until late January, and we can only be given two days for the test.

There was no other way, so I broke down the layout into several parts and conducted an experiment in a small, dark room. I have now collected some data.

"Has the microwave anechoic chamber at China Electronics Technology Group Corporation (CETC) become overwhelmed with resources?"

"Is a fully-equipped, giant microwave anechoic chamber still under construction?"

When Lin Dong saw the reply email, his heart skipped a beat.

The microwave anechoic chamber is overloaded with resources, a problem even more serious than the CETC AESA radar exceeding size limits.

The AESA radar is too large; this is due to the inadequacy of China Electronics Technology Group Corporation (CETC). At worst, they can give us a deadline, and if it's not completed by then, we can simply take over the business.

However, the construction of the microwave anechoic chamber is not yet complete. This is not something that can be accomplished by technology alone; it is a matter of building a major scientific research project.

"This is because industrial development has failed to keep up with technological advancements...we've hit an industrial bottleneck."

"Unexpectedly, the breakthrough in gallium nitride electronics technology, which led to a comprehensive upgrade of domestic radar systems, has become an obstacle to my own projects..."

Lin Dong rubbed his forehead, his mind racing as he considered various solutions.

A microwave anechoic chamber, as the name suggests, is a space built on the ground using shielding and absorbing materials, creating an environment free from microwave interference and reflection, with an infinitely open electromagnetic field.

In such a dark room, radar and electronic warfare equipment can realistically simulate their actual performance in the sky.

In a normal natural environment, radar beams will bounce back when they encounter objects.

This bounce wave is a deadly source of interference for a radar that has not yet completed its commissioning.

If this source of interference is not eliminated, the radar will not be able to complete precise adjustments, and thus will be unable to accurately detect targets in actual combat.

Therefore, a microwave anechoic chamber that can absorb and shield all radar beams, eliminate reflected beams, and create an infinitely spacious electromagnetic environment is the core scientific research building for the design and manufacture of long-range radar.

This is especially true for electronic warfare aircraft, which require a large amount of electronic warfare equipment and have significant electromagnetic compatibility issues, as they are prone to self-destruction if not handled carefully.

A fully functional giant microwave anechoic chamber that can accommodate the entire fighter jet and simulate various electromagnetic environments is of paramount importance.

But now.

The fully functional giant anechoic chamber that can accommodate the J-16D fighter jet is still under construction, and there is a waiting list for a large anechoic chamber that can meet the initial testing needs... This has stalled the entire J-16D project.

in other words.

Chengdu Aircraft Industry Group (CAC) is facing another bottleneck.
