The whole laboratory seems to have a sense of science and technology, and many places use electronic translucent screen design, which makes Su Yun find it quite interesting.

After sending Su Yun and them, Lu Guangzhou said to them, "I'll pick you up in a month", and then left in a hurry with those soldiers, presumably their project progress should be very nervous, otherwise how could they pull the next old face to find Meng Meng for help?

At this moment, a person came out of it, a woman around fifty years old, with a heroic temperament, Su Yun has never been in the habit of underestimating anyone, even if the other party is a girl.

So when this grandmother-like person appears here, it must be because she has her excels.

When Meng Meng saw someone coming, she immediately laughed and ran over and shouted:

"Grandma Xu, hehe, I'm here again!"

Grandma Xu was obviously very happy to see her running over like an elf, squatting down and picking up Mengmeng from the ground.

"Hey, does Xiao Mengmeng miss grandma?"

"Hehe, I think about it, I think about it!

"Haha, it's good to think about it, grandma misses you too!"

After watching the conversation between the two, the corners of Su Yun's mouth twitched, no matter who she told her, Mengmeng is an eighteen-year-old girl, she probably won't believe it, right? This is obviously a thirteen or fourteen-year-old cute Lori!

"Hehe, don't you tell grandma who this big brother is?" the two of them were greasy for a while, and Grandma Xu asked with a smile.

"Hello Grandma Xu, my name is Su Yun, and I am a student at Peking University. Su Yun took the lead in introducing himself.

"Oh, you're Su Yun. Grandma Xu naturally heard Su Yun's name, and nodded thoughtfully: "Hello, my name is Xu Xiuqi, and I am the main person in charge of this project, you are the same as Mengmeng, just call me Grandma Xu." ”

"Grandma Xu, let me tell you, my brother is so powerful! much, much more powerful than Mengmeng!" Mengmeng said in her arms.

"Ah, much, much more powerful than our cuteness?" said Grandma Xu pretending to be surprised.

"That's right, I'll tell you, Grandma Xu, the principle of air flow last time ......"

As they spoke, they walked towards the laboratory, listening to Shumeng brag about how good her brother was and how good he could do anything, which made Grandma Xu, who was still listening to Lehe at first, more and more surprised.

It can be said that in the Department of Physics of the Chinese Academy of Sciences, there are no people who do not know Mengmeng, who are only in their teens, but in debates again and again, their theories have been overturned, and the most important thing is that they academicians have to accept what Mengmeng said! Because what they say is right, even if she is just a teenage girl, you can't say that what she said about 1+1=2 is wrong, right?

Right is right, wrong is wrong. In the Chinese Academy of Sciences, people are never looked at by age and generation, and those who are capable live in it, and those who are capable should be respected, which is the concept of everyone here.

So although Shu Mengmeng did not join the Chinese Academy of Sciences, she soon became a little star in the Department of Physics of the Chinese Academy of Sciences.

And she found out that what their little star said today was the principle and theory that they couldn't refute in the first place, and it was actually taught to her by this young man named Su Yun!

This Su Yun, isn't he engaged in mathematics? Why did he come to physics?

She couldn't help but think so.

However, what made her even more unexpected was that in the next month, their three views meeting was completely subverted by Su Yun.

————————

Coming to a screening room, Xu Xiuqi put down the Mengmeng he was holding, and then asked Su Yun to sit down in the position below, and began to tell Su Yun about the main content of their project.

"The name of our project is called: Flying Eagle Project, and the main thing is to complete the design of the Flying Eagle fighter. Among them, the Flying Eagle fighter is only our imagination at present, because the requirements for it are very strict, so there is no complete design so far.

First of all, the survivability requirements, the Flying Eagle needs to achieve: low radar detectability, low infrared radiation characteristics, excellent electronic countermeasure performance, and vulnerability.

The second is multi-mission capability, which requires the Eagle to have: strong target detection and external information synthesis capabilities, excellent situational awareness and information sharing capabilities, over-the-horizon multi-target attacks and large off-axis angle omnidirectional attack combat air combat capabilities, precision strike capabilities against ground and sea surface targets, and the ability to adapt to complex meteorological conditions and use them in a wide area.

Finally, it is required that the amount of fighter spending needs to be controlled to a certain extent as much as possible to ensure a relatively high cost performance. ”

Xu Xiuqi said above, Su Yun listened meticulously, and Mengmeng sat next to Su Yun, looked left and forward, and secretly smirked twice from time to time.

Every time I come here alone, I'm so scared, but this time my brother came with me, and I don't feel afraid at all!

“… When it comes to performance, here's what we're aiming for at the moment.

The length of the fuselage is controlled within 15 meters, the wingspan is within 10 meters, the height is less than 4 meters, the wing area is 30 square meters, and the empty weight is kept below 10 tons, so that the maximum take-off weight can be guaranteed to be about 21 tons.

As for the engine, we aim for it to have an afterburner thrust of about 150 kN, a maximum flight speed of Mach 2.2, a practical ceiling of 25,000 kilometers, and a combat diameter of 5,000 kilometers.

There are also some detailed data such as load, bomb load, and fuel load, which you can take a closer look at to understand our goals, so that we can make the most perfect design correctly. ”

Just to introduce the content of the project, Xu Xiuqi talked for more than 40 minutes, and many of them were directly skipped, let him go down and read the information directly to understand, otherwise it is estimated that even if it is a day today, he will not be able to finish it.

After understanding the content of the entire project, Su Yun suddenly asked:

"Grandma Xu, in my opinion, this project should not be difficult, right? Why do they all say that this is an impossible project?"

After talking for a long time, Xu Xiuqi, who had a dry mouth, was drinking water to moisten his throat, when he heard Su Yun come to such a sentence, and he sprayed directly on the ground with a mouthful of water regardless of his image.

"What? It's not difficult, didn't you understand what I just said?" she looked at Su Yundao speechlessly.

"Take our most advanced fighter in China as an example, its fuselage length, wingspan, and height are: 16.9, 11.5, and 4.8 meters, afterburner thrust of 93.1 kN, maximum flight speed of Mach 1.8, practical ceiling of 18,000 kilometers, combat diameter of 2,500 kilometers.

The three dimensions of the flying eagle we designed are 15, 10, and 4 meters, which are smaller, but the afterburner thrust of the eagle is required to reach 150 kN, the maximum flight speed is to reach Mach 2.2, the practical ceiling is 25,000 meters, and the combat diameter is 5,000 kilometers.

Alas, this is a wall that is almost insurmountable for us at the moment, and it is not difficult, and it will not be so many years that this project has not progressed at all.

So, this project is called the impossible project, and now you know, how hard this project is, right?"

Su Yun nodded thoughtfully, and then said:

"Give us a month, and after a month, Mengmeng and I will give you the design sample. ”

Xu Xiuqi almost stumbled.

Who is this? Did you listen to what I said?
