Chapter 56: Person in Charge

Stealth fighters aren’t as invisible as people imagine, like invisibility cloaks.

The real principle is actually very simple. The basic principle is to make the radar unable to detect the existence of the aircraft.

A radar detection cannot detect 360 degrees without blind spots. The length of the radar line may vary due to various factors.

“The reason why I said not to study the long-distance launch is because we have better and more cost-effective ones. Why not choose the latter?”

Shen Sangyu said, turning back to write and draw on the blackboard.

She briefly drew the position of the earth and the radar position on the blackboard.

She wasn’t sure what the current radar scanning distance was, so she simply drew a distance.

Qin Duanshan stared at Shen Sangyu’s drawing without blinking, his eyes suddenly lighting up after the drawing was completed.

He said, “Go on.”

Shen Sangyu nodded, “First of all, the term invisibility is not unfamiliar to everyone.

Maxwell had proposed it more than a decade ago. In my words, what we need to do is not only the aircraft, but also how to make the radar invisible and the coating needed to make the outer layer of the aircraft.”

Shen Sangyu spoke freely in front of them, and everyone’s eyes went from initial enthusiasm to fear, and finally even took out their work notebooks to start recording.

Because many of the things Shen Sangyu said, they didn’t understand at all.

Shen Sangyu didn’t intend to make everyone understand all at once. After all, what she said was the essence and theory summarized by aerospace scientists all over the world in the next few decades.

She picked and chose some of the materials that were currently available, but even so, she talked for several hours.

Qin Duanshan’s assistant saw it and immediately went to boil hot water, constantly refilling everyone’s cups.

While Shen Sangyu was talking about the theory, no one ran to the toilet, and everyone listened intently.

Shen Sangyu was tireless when it came to work time. She didn’t know how much water she drank after she finished speaking, but even so, her mouth was still dry and her throat was slightly sore.

After a moment of hesitation, Shen Sangyu glanced at her watch. It was already four o’clock in the morning.

Looking at Qin Duanshan and others, no one had a tired look in their eyes. Those eyes full of thirst for knowledge kept looking at her.

Shen Sangyu gritted her teeth and spoke for another two hours. In the end, she couldn’t hold on any longer.

After hesitating for a while, she said to Qin Duanshan, who was still immersed in the huge knowledge shock and hadn’t reacted, “We’ve talked about it today. How about taking a break first?”

In fact, doing scientific research is somewhat miserable. The original owner’s health in this life was not very good.

She stayed up all night and her mind was confused. If it was in the previous life, once she did important research, she would not stop for three days and three nights.

Shen Sangyu sighed and thought that it was no longer possible now. Now she could hardly lift her eyelids.

If she fell asleep while talking, how embarrassing it would be!

However, Qin Duanshan did not respond, and Shen Sangyu weakly called out twice more.

Qin Duanshan finally reacted.

Subconsciously, he glanced at Shen Sangyu’s pale face, stood up and said, “Okay, you’ve worked hard today.

Let’s talk about other things tonight… no, let’s talk about other things at noon today.”

Shen Sangyu: “…”

It was already six o’clock in the morning, and she could only sleep for six hours at most.

She hadn’t slept so short since she traveled through time.

But these six hours of rest time are very luxurious for those who do scientific research.

After all, they sometimes have to watch the data all night, because the data may change in the next second, so there is no way to entertain themselves.

Shen Sangyu cheered up and nodded.

Qin Duanshan personally took Shen Sangyu to the resting place. He mainly wanted to ask a lot of things, but Shen Sangyu made it clear that she didn’t want to say anything, and Qin Duanshan didn’t ask anything.

After walking out of the laboratory, Shen Sangyu suddenly paused, “Teacher Qin, can I call the military district to report my safety?”

Their research was not a top-secret project, so Qin Duanshan pointed to the office.

Shen Sangyu did not forget to call Wen Qingchuan, so she quickly dialed the number, and soon someone went to ask Wen Qingchuan to answer the phone.

Not long after, a slightly panting male voice came from the other end of the phone, “Sangyu, it’s me, are you safe?”

When Shen Sangyu heard this voice, she suddenly felt that her empty heart was filled.

She hummed softly, and she picked and chose to tell the story again, which did not involve confidential content.

“In short, I have to help Teacher Qin deal with things before I can go home, which may be delayed a little bit than originally planned.”

Wen Qingchuan is not like other men. He thinks it’s not good for women to go out and show their faces.

He even heard that Shen Sangyu was quite good at studying airplanes.

“Then you should pay attention to rest more. Can you handle your work and study well?

And do you need money? I saw that you didn’t even bring the passbook in your room…”

Wen Qingchuan didn’t talk much in the past, but when he heard that Shen Sangyu’s return date was uncertain, he couldn’t help but worry. After all, he had been personally taking care of Shen Sangyu’s daily life in the past few months.

Shen Sangyu didn’t interrupt Wen Qingchuan’s words. She answered whatever the other party said.

“Don’t worry, I just want to stay for a few more days. Teacher Qin and others will handle the rest by themselves.

Besides, my uncles and uncles only taught me a little bit before. I will come back after the knowledge is exhausted.

As for money… The institute should provide food and accommodation, right?”

Shen Sangyu said, and couldn’t help looking up at Qin Duanshan.

Qin Duanshan’s mouth twitched, but he still nodded, “Food and accommodation are provided.”

Shen Sangyu breathed a sigh of relief. Although she had a spirit of selfless dedication, at least she couldn’t let her pay for it herself.

“Did you hear that? Food and accommodation are provided, so don’t worry.” Shen Sangyu said while holding the phone.

Wen Qingchuan smiled, and gave a few more instructions before hanging up the phone.

Seeing that there was no sound, Shen Sangyu put the phone back.

Qin Duanshan heard it clearly and couldn’t help but sigh, “Your husband cares about you a lot.”

Shen Sangyu nodded, “That’s true, he is very tolerant of me.”

Whether it was the original owner or herself, Wen Qingchuan didn’t complain about not cooking, not working, and even not cleaning the room.

Every evening after training, she was tired and hungry, and she had to do it herself.

Although she didn’t have to do these things, at least compared to the family compound, Wen Qingchuan was miserable.

Of course, she didn’t do nothing. She certainly didn’t think about cooking. On weekdays, she would still clean up when she had time.

Qin Duanshan looked at Shen Sangyu without saying much, and took Shen Sangyu back to the rest area. The assistant also brought the food at this time.

“You rest first. When the time comes, someone will knock on the door. We will have a meeting after you wake up.”

Shen Sangyu was stunned for a moment, “Meeting?”

Qin Duanshan smiled and nodded, “Yes, you can be said to be half the person in charge of the stealth fighter now!”

Shen Sangyu: “!!!”

“You mean, this is your next research direction?”
