Dreaming back to 90, starting to develop B2 bombers!

: In what age are we still using traditional tailfins? ! [Please vote for comments and flowers]

Yu Bei had already seen the gate of Longke Academy from a distance.

However, what surprised Yu Bei was that the gate of Longke Academy was not as grand as he imagined.

On the contrary, it is quiteLow-key, if it weren’t for the plaque indicating his identity,

It is really possible for ordinary people to mistakenly identify which relevant department this is.

Geographically, Longke Academy is also remote, and it took the car more than an hour to get there.

“It’s a bit far and a bit shabby, Yu Bei, don’t dislike it.”

In the car, Hu Weinan laughed and said.

“Dean Hu, if you are here, we are engaged in scientific research, not performances.”

Yu Bei smiled and shook his head.

“coming!”

“Tsk, I want to see who this young man is!”

“You have to ask clearly and see what his abilities are. Don’t just draw a picture! If you have drawings but no skills, you still can’t make this bomber!”

A group of academicians wearing white coats stood in front of the gate, watching the motorcade coming, and their eyes suddenly lit up!

Even the deans of several branches couldn’t hold it in any longer, their eyes gleaming.

“Old Liu, have you thought about what to ask?”

Wu Zong, the dean of the physics branch, took a breath and asked Liu Hong, the dean of the optics branch next to him.

“No, his bomber basically has nothing to do with the field of my research. I can’t figure out why. Even if he can really lead the development of stealth bombers, he can’t be proficient in all fields, right?”

Liu Hong shook his head and said.

“Hey, I’m very curious as to what materials Yu Bei will use to absorb radar electromagnetic waves!”

Gou Yi from the Materials Branch said with a blink.

Wang Zhengze on the side had his eyebrows lowered. He thought differently from these people. Although he was full of things he wanted to know from Yu Bei, he still decided to stop and ask Yu Bei again.

So that if something goes wrong, everyone will be embarrassed!

With this thought in mind, the special car to greet Yu Bei had already arrived at the gate of Longke Academy.

Yu Bei and Hu Weinan got out of the car together.

“So young?!”

“Hmm?! This guy is so handsome!”

“Tsk, tsk, that’s incredible, I’m almost as energetic as I was back then!”

“What?! Lao Hou, do you still want to be shameless? If you were like this, your blind date would dislike you?”

“roll!”

A group of academicians were surprised when they saw Yu Bei coming down. Although they knew that Yu Bei was very young, when they actually saw him, they were still shocked by Yu Bei’s youthfulness!

Yu Bei’s youthful vitality made them feel that they were dying!

“Haha, everyone, this is Yu Bei, the chief designer of our stealth bomber!”

Hu Weinan said that because everyone present already knew that the design was designed by Yu Bei, he had nothing to hide.

A group of people were even more shocked when they heard what Hu Weinan said!

Even though they guessed that Yu Bei might host this project, no one expected that it would be decided so quickly!

“Isn’t this…a little too fast?!”

“Oh, it’s too hasty. No matter what, we have to see his true ability first before making a decision!”

“This decision is indeed too hasty!”

And Yu Bei was a little surprised when he saw everyone’s performance. It seemed that these academicians only knew about this now!

“Classmate Yu Bei, Academician Hong from our college has a question for you. I wonder if it’s inconvenient for you?”

Wu Zong, dean of the physics branch, looked at Yu Bei and said.

Yu Bei smiled slightly and nodded: “Okay.”

Wu Zong also nodded, and then gave the middle-aged man next to him a look.

“Classmate Yu Bei, I would like to ask, why did you design the stealth bomber without a tail? Was the aerodynamic force insufficient at that time? How to ensure the vertical safety of the bomber when changing course?”

The middle-aged man can stand up and ask. This is an extremely critical question discussed by all the academicians of their physics branch last night, including Dean Wu Zong!

Wang Zheng, who was on the side, his eyes narrowed when he heard this question. Although he had an argument with Wu Zong a few days ago, he had to admit that this question was indeed a good one!

Hearing this question, Yu Bei smiled, and then said slowly,

“The reason why the stealth bomber I designed does not have a vertical tail is that the aircraft is yaw-neutral, which means that when the bomber turns left or right, it will not generate aerodynamic force to return to center.”

“The bomber is controlled by the speed brake-rudder on the trailing edge of the outer wing section. The speed brake-rudder can be cracked up and down on both sides. The cracks can be used as speed brakes at the same time. When cracked asymmetrically, they can be used as rudders. Due to the attachment of the flying wing surface, With the presence of the surface layer, the airbrake and rudder will directly crack by 5 degrees!”

“So in normal flight, the speed brakes and rudders on both sides are at 5 degrees.The open position can take effect immediately when control is required. However, the opened speed brake-rudder will affect the stealth effect of the aircraft, so when the bomber arrives in the war zone, the speed brake-rudder must be fully closed. ”

Yu Bei didn’t think anything, and explained this issue in a smooth and fluent manner, as if the bomber had already been built!

Such quick thinking made Wu Zong’s face change greatly, and the academicians of the physics branch behind him also looked shocked!

After carefully thinking about what Yu Bei said, everyone in the physics branch figured it out!

What Yu Bei said is absolutely feasible!

Wang Zheng also had trembling eyes, and his hand holding the cane was trembling!

As the dean of the aerodynamics branch, he is naturally one of the top people in aerodynamics!

At present, Yu Bei’s understanding of aerodynamic forces and his handling of specific problems have definitely proposed a new direction of thinking for the entire aerodynamics!

But looking at everyone’s expressions, Yu Bei suddenly remembered a joke from his past life.

In what age are you still using traditional tailfins? !

“this……”

The academician who came out to ask questions on behalf of the entire physics branch looked shocked and didn’t know what to say for a moment!

This is different from the plot they rehearsed yesterday!

Yesterday, even if they expected Yu Bei to answer, everyone gave various answers, but they never expected that Yu Bei would just say everything without thinking!

None of the rhetoric I prepared before is of use here! !

Hu Weinan, standing behind Yu Bei, felt very happy when he saw such a scene, and secretly gave Yu Bei a thumbs up.

He originally thought that Yu Bei would be troubled by the stubborn old guys below him, and he was even ready to come out to smooth things over.

In the end, who knew that Yu Bei had directly turned against the guests!

On the contrary, it gave them a warning!

“Okay, thank you academician for your question. Who’s next?”

At this moment, Yu Bei smiled.

“I come!”

A group of academicians were hesitant. After all, no one wanted to be as embarrassed as the person just now and couldn’t get off the stage!

But at this moment, a voice suddenly rang out, and everyone’s expressions changed when they saw it!

It’s actually Gou Yi, the dean of the Materials Branch!

Even if other branches have questions, they always send academicians below to ask, but this one actually wants to go directly to the field in person? ! .
