Chapter 97: If you want to do it, do the most advanced one [Please subscribe]

"Although all the participants in the discussion meeting are experts from various research institutes, you must be confident in your own lifting body wing canard layout. Since Academician Song asked you to attend, you must be confident."

When Xu Chongxing saw that Xu Yuan was slow to speak, he thought that he was a little nervous about this kind of situation.

He reached out and patted her shoulder and said, "I'll go with you tomorrow."

Xu Yuan was not worried about his aerodynamic layout, but he was a little excited at the thought of introducing it in front of so many designers.

After coming to his senses, he immediately nodded.

"I understand, Professor Xu."

After saying that, he did not stay with Xu Chongxing for too long and left to prepare for tomorrow's discussion meeting.

……

The next day.

Half past eight in the morning.

Xu Yuan and Xu Chongxing arrived at the Aviation Industry Corporation of China headquarters on time.

And soon he met Academician Song Wencong.

Besides.

There were also several other people from the Jincheng Aircraft Design Institute.

"Xiao Xu, come here."

Hearing the familiar voice and seeing Academician Song Wencong waving at them, the two of them immediately walked over.

"Academician Song."

Xu Yuan took the initiative to greet Song Wencong.

Then he politely greeted the other researchers around him.

As soon as he finished speaking, a familiar voice suddenly came from his ear.

"Junior brother."

"You are here to attend this discussion meeting as well."

Xu Yuan turned his head and looked behind him, and immediately noticed that Zhao Yuefeng, an assistant researcher at the Jincheng Aircraft Design Institute, was walking towards him, so he responded with a smile.

"Hello, senior brother."

"Professor Xu brought me here."

Zhao Yuefeng was a little surprised when he first saw Xu Yuan. After all, his junior brother was currently a student and normally could not attend such an internal meeting.

However, considering that Xu Chongxing cares very much about Xu Yuan, and the other party seems to have a good relationship with Academician Song.

I soon felt relieved.

Before and after approaching, he did not forget to greet Xu Chongxing: "Hello, Professor Xu."

Xu Chongxing nodded to Zhao Yuefeng, then turned his gaze to Song Wencong in the middle.

"What's the situation now? Are the higher-ups not planning to develop our latest generation of stealth fighter jets for the time being?"

"Ah~"

Song Wencong met Xu Chongxing's gaze and sighed first, then went on to describe the current situation.

"Those people from Fengtian and Xijing Research Institutes proposed upgrading the current third-generation fighter jets, but the group is still a little hesitant."

Having said this, he suddenly seemed to have thought of something, and his tone suddenly became higher and full of confidence again.

"But today we are confident that we can convince the group."

As he finished speaking, he deliberately looked at Xu Yuan.

The meaning is self-evident.

Xu Yuan naturally understood Song Wencong's thoughts and did not remain silent at this time.

He immediately took over the conversation and added.

"If we are going to make fighter jets, we have to make the most advanced ones. Otherwise, how can we compete with the latest generation of fighter jets overseas?"

"Xiao Xu said it well." Song Wencong gave him an appreciative look.

Xu Chongxing's face was full of pride.

This sentence also attracted the special attention of several researchers nearby, and they couldn't help but smile and tease Xu Chongxing.

"Lao Xu, is this your graduate student?"

"Xu Yuan is currently only a freshman in our Engineering Mechanics Department, but he has already taught himself fluid mechanics and aerodynamics." Xu Chongxing answered directly without hiding anything on this matter.

This made many people visibly stunned.

"Freshman?"

A question mark emerged in my mind.

Under normal circumstances, it would be fine for Xu Chongxing to bring his graduate students to participate in such symposiums to learn and see the world.

But I have never seen anyone teaching undergraduate students, especially those who have just enrolled.

Even if I teach myself fluid mechanics and other related knowledge, to what extent can I achieve in a limited time?

This is somewhat of a joke.

But since we were old friends, we didn't say much.

"It seems that you, Mr. Xu, like this student very much."

"I'm a little curious."

However, Zhao Yuefeng on the side widened his eyes and asked Xu Yuan in disbelief.

"Junior brother."

"Are you really a freshman?"

"How can it be."

Ever since he met Xu Chongxing and Xu Yuan at Jincheng Station, he had always believed that Xu Yuan was Xu Chongxing's graduate student.

After all, he also graduated from the Department of Engineering Mechanics of Qinghua University, but he had never seen any professor bring undergraduates to the research institute. In addition, seeing Xu Chongxing's proud eyes, he naturally had no doubts.

As a result, he never expected that Xu Yuan was actually an undergraduate freshman.

No matter how hard I tried, I couldn't imagine it.

I don’t know what kind of ability Xu Yuan has that can allow Professor Xu Chongxing to achieve this level.

"Brother, I am indeed a student of the Qinghua Class." Xu Yuan looked at Zhao Yuefeng and answered truthfully.

At this time, Song Wencong saw that everyone was concerned about Xu Yuan's academic qualifications, so he smiled and spoke up to help.

"Although Xiao Xu has just started college, he can easily give people great surprises."

Thinking back carefully, when he first learned about this situation, he was also a little stunned. He couldn't believe that someone could design such a nearly perfect aerodynamic layout of a fighter jet during the undergraduate stage.

When everyone saw that even Academician Song Wencong gave such a high evaluation, they immediately put away their previous contempt.

The look he gave Xu Yuan also became serious.

Everyone present knew about Academician Song Wencong's achievements. In addition to being an academician of the Chinese Academy of Engineering and an expert in domestic aircraft assembly design, he also presided over the research and development of the third-generation fighter jets that are currently entering service.

Since Academician Song Wencong could say that, he must have some outstanding qualities.

Noting the gazes of several senior researchers in the institute, Song Wencong smiled but said nothing, deliberately keeping the matter in suspense for the time being.

Facing the gazes of several researchers, Xu Yuan remained calm and unperturbed.

It didn't cause any pressure.

He was so impressed by Zhao Yuefeng.

He asked himself that if he were facing the gazes of several researchers, he would probably be overwhelmed with stress and feel like he had done something wrong.

And at this time.

The researcher who first teased Xu Chongxing looked thoughtful.

"Xu Yuan..."

"I remember seeing this name in the newspaper."

"It's also from Qinghua University."

"But he seems to be a student of mathematics."

After expressing his doubts, he immediately raised his eyes and looked at Xu Chongxing, seeking answers from him.

Xu Chongxing immediately smiled when he heard that. He did not choose to answer personally but passed the conversation to Xu Yuan.

"Xu Yuan, you should speak for yourself."

Hearing Professor Xu's words, Xu Yuan had no choice but to look at the researcher.

"I am studying both the Department of Mathematics and the Department of Engineering Mechanics. If nothing unexpected happens, it should be me that you saw in the newspaper."

"I see."

The researcher suddenly realized what was going on and then began to praise generously.

"It's really not easy to publish a paper in a top journal like Annals of Mathematics at such a young age."

"And yet Old Xu and Academician Song think so highly of me."

"not simple."

Xu Yuan did not expect that several researchers had already praised him so much before the discussion even started.

I can't help but worry about them.

After all, if you have finished speaking now, there will be no need for praise at the discussion meeting later.

However, Xu Yuan did not notice that the confidence on Zhao Yuefeng's face was gone.

There is a sense of mental breakdown.

Thinking about how Xu Yuan was highly valued by Professor Xu Chongxing during his freshman year, he ended up studying mathematics at the same time and was able to publish mathematical academic papers in the Annals of Mathematics.

It suddenly made him feel that he had been wasting his time all these years.

I thought that after graduating with a doctorate, I would be able to successfully get a job at the Jincheng Aircraft Design Institute, and that working as a researcher assistant would be quite impressive.

Now I understand what it means that there is always someone better than you, and there will always be times when you cannot beat others.

Just as he was immersed in this state, he was suddenly awakened by the shout of Academician Song Wencong.

"The discussion meeting is about to begin."

"Let's go in."

When everyone heard this, they naturally did not delay any longer and immediately followed Academician Song Wencong to the place where the symposium was held.

Xu Yuan followed everyone into the venue and immediately saw the nameplate on the table.

In addition to the Jincheng Aircraft Design Institute, it also includes the Fengtian Aircraft Design Institute and the Xijing Design Institute. As Academician Song Wencong said, today is indeed an important meeting.

Because he was in the team of Jincheng Aircraft Design Institute, no one paid much attention to him.

Then he found an inconspicuous seat and sat behind Xu Chongxing.

Soon after all the participants arrived, Lu Dongming, chairman of Aviation Industry Corporation of China, stepped in and sat in the middle.

"Everyone, please take a seat."

"Let's relax a little during today's discussion. Feel free to exchange any opinions you have."

“It’s mainly about determining our next steps.”

Lu Dongming came to the middle seat and when he saw that everyone else had stood up, he quickly raised his hand and spoke warmly.

As the words fell, everyone else took their seats, causing the meeting room to fall into silence.

Although the people present did not belong to the same institute, they were all very familiar with each other in private. For example, Academician Song Wencong was at the Fengtian Institute before he took charge of the Jincheng Aircraft Design Institute.

But right now, at this discussion meeting, there is only healthy competition.

Everyone hopes that their plan will be approved.

After about a minute, Gao Yuhe, a designer from the Fengtian Aircraft Design Institute, spoke first.

"At present, our third-generation fighter jet J-10 has been successfully produced and will be put into service this year."

"For the research and development of the next fighter jet, I suggest improving it based on the J-10 to make the technology more mature."

"To lay a solid foundation for the development of more advanced fighter jets."

According to tradition, the research and development of various equipment will not stagnate.

When a model is announced to be officially put into service, a more advanced model must keep up with the pace of development.

As for Gao Yuhe's proposal, Huang Yunliang, a researcher at the Xijing Aircraft Design Institute, also expressed his approval after a brief thought.

"As our various technologies mature, there is indeed still room for improvement in the third-generation fighter."

"I also agree to develop the J-10 modification."

Lu Dongming took the opinions of the two designers to heart, but naturally would not make a decision immediately.

After a two-second pause, he turned his gaze to Song Wencong who had not spoken.

"What do you think, Academician Song?"

Song Wencong, who had been listening to other people talking, became more serious after being asked the question.

Then he directly rejected Gao Yuhe and Huang Yunliang's proposal.

"No one knows the flaws of our third-generation aircraft better than me. In addition to being unable to refuel in the air and lacking power, there are also unscientific aspects in the aerodynamic layout."

"This kind of product, which has not yet deviated from the development ideas of the second-generation aircraft, cannot catch up with the international level at all."

"Even if we improve on this basis, it will not be as good as other countries' fifth-generation stealth fighters."

Perhaps he did not expect that Song Wencong, as the chief designer, would criticize the defects of the third-generation fighter jets so much, which made Lu Dongming even more interested.

The next second, he took over the conversation and asked, "What kind of fighter jet do you think we should develop, Academician Song?"

"The most advanced fighter jet."

Song Wencong said this in a firm tone.

"A stealth fighter that can rank among the world's top fighters is a national heavy sword that can deter all forces around the world."

"Our technology has matured. If we want to develop fighter jets, we should develop the most advanced fighter jets."

Although he repeated what Xu Yuan had said before, his tone was powerful and resounding.

He took control of the whole situation in an instant, making the atmosphere somewhat subtle.

Deep down, as aircraft designers, we all naturally hope to develop fighter jets that are not inferior to those overseas.

This can ensure its international status.

Avoid the helpless situation of being beaten if you fall behind.

But sometimes we have to bow to reality. With limited manufacturing level and technology, it is simply not enough to develop a stealth fighter.

If you invest a lot of resources, money and time, only to declare the project a failure.

That was a huge blow to everyone.

The consequences will be unimaginable.

It is precisely because of this that Huang Yunliang and Gao Yuhe chose a relatively conservative option.

Continue to improve based on the third-generation fighter jets.

Improve the comprehensive performance of existing fighter jets and accumulate experience and technology.

The thought stayed here, and Gao Yuhe and Huang Yunliang quickly came to their senses and expressed their objections.

"I don't agree with Academician Song's opinion. I think our current technological level is still insufficient and we are simply unable to develop the latest generation of stealth fighter jets."

"Take America's most advanced stealth fighter jet for example. From project approval to first flight finalization and then to production, how much time and money was spent in between."

“That complexity is not appropriate for our current situation.”

"So I maintain my previous point of view and still improve it based on the third-generation fighter."

As Gao Yuhe first gave his reasons for opposition, Huang Yunliang on the opposite side was not to be outdone and spoke up.

"The development cycle for the latest generation of stealth fighters is too long, and I think it's too early at this stage."

"If the Jincheng Aircraft Design Institute is unable to improve the J-10, our Xijing Aircraft Design Institute can take over the project."

As the chairman of Aviation Industry Corporation of China, Lu Dongming holds decision-making power, which also represents enormous pressure and responsibility. Every decision he makes must be considered in light of the actual situation.

Judging from the current situation, it is indeed too early to start developing the latest generation of stealth fighter jets.

You should know that the most advanced stealth fighter jets overseas took a long time just to be formally finalized.

However, in order to save Song Wencong's face, he paused for a few seconds before speaking in a more tactful manner.

"Right now we don't even have a design for the appearance of a stealth fighter, so it's a bit arbitrary to start a research and development project at this moment, so I hope that the Jincheng Aircraft Design Institute will continue to improve the existing third-generation aircraft."

As Lu Dongming finished speaking, Gao Yuhe and Huang Yunliang both breathed a sigh of relief.

They were really worried that the group would agree to launch the stealth fighter project, which would then create an unmanageable situation.

Although they failed to get the third-generation fighter improvement project, there was nothing wrong with handing it over to the Jincheng Aircraft Design Institute.

After all, this third-generation fighter was developed by them, so it would be easier to improve it.

On the other hand, Song Wencong still looked confident at this time, and then announced something in front of everyone's extremely surprised eyes.

"It is indeed difficult for us to develop a stealth fighter, but it is not impossible."

"What if I say we have finalized the aerodynamic layout and shape, and plan to complete the first flight within three years?"

At this moment, everyone sitting in the conference hall had an expression of disbelief on their faces after hearing what Academician Song Wencong said. They really couldn't believe that these were true things.

Mainly because Jincheng Aircraft Design Institute has been developing domestically produced third-generation fighter jets.

Basically, the focus of the entire institute is on this.

In this case, there is no time to design the aerodynamic layout of the latest generation of stealth fighter jets.

"The aerodynamic layout requirements for stealth fighters are extremely high, and even if the design has already begun, it is impossible to complete it so quickly."

“Not to mention that it only took three years to complete the first flight.”

It’s not that Gao Yuhe intentionally targeted Song Wencong, but this matter is really hard to believe.

Stealth fighters need strong maneuverability to fly at extremely high speeds, which makes it very important that the aerodynamic layout is scientific. It is not the case that you can just pick up any aerodynamic layout and use it.

This requires careful calculations and simulations, and only after obtaining detailed results can it be formally finalized.

Now Song Wencong said that it would only take three years to achieve the first flight of the latest generation of stealth fighter.

No one will believe it.

Compared with Gao Yuhe from Fengtian Institute, Huang Yunliang was more concerned about the aerodynamic layout.

I immediately took over the conversation and asked, "Is it a conventional aerodynamic layout with an outward-inclined vertical tail like those overseas?"

"It's still a canard aerodynamic layout." Song Wencong shook his head and said.

When Huang Yunliang heard this, a look of disappointment suddenly appeared on his face. He was obviously not optimistic about this aerodynamic layout.

"Our third-generation fighter jets use a canard layout, and its advantages and disadvantages are very obvious."

"It is not suitable for use on stealth fighters."

"We still have to adopt the conventional overseas aerodynamic layout."

After Gao Yuhe and Huang Yunliang expressed their opinions, several other people from the Jincheng Aircraft Design Institute became excited, thinking that it was Academician Song Wencong who designed the aerodynamic layout of the stealth fighter.

Especially considering that Song Wencong had promoted this discussion meeting during this period, it seemed more and more that it was intentional. The main reason was that they had great confidence in Song Wencong's ability and did not think it was surprising that Song Wencong designed the aerodynamic layout of a stealth fighter.

After all, without Song Wencong, the third-generation fighter jets would not have been successfully developed and put into production.

At this time, Zhao Yuefeng, who was sitting in the back row, also had a smile on his face and was very much looking forward to the project being approved.

Because from the current situation, if the latest generation of stealth fighter research and development project is to be successfully approved, it will inevitably fall into the hands of their Jincheng Aircraft Design Institute.

As a member of the institute, participating in this kind of project is definitely a good experience for him.

As for Lu Dongming, he was too busy making a decision at this time. He was very interested in the appearance plan mentioned by Song Wencong.

If this aircraft can really achieve its first flight within three years, it will definitely become an international event that will shock the world's forces.

Therefore, even if there is a slight possibility, we must grasp it firmly and not let it slip away.

"Academician Song."

"Why don't you introduce the aerodynamic layout plan to everyone first, so that we can discuss it."

"how do you feel?"

Since Song Wencong took the initiative to speak out, he must use this aerodynamic layout and appearance plan to convince everyone.

Get the approval from the higher authorities to formally launch the stealth fighter project.

But he was not the one who presented the plan.

No matter what, the lifting body wing canard aerodynamic layout design was designed by Xu Yuan, and the designer should personally explain the various advantages of the design.

Otherwise, if it were him, wouldn't he be suspected of stealing the achievements of his juniors?

As a senior, he can’t wait to cherish and protect such talents among the country’s younger generation.

I definitely won't do something like killing the goose that lays the eggs.

This is also the reason why he insisted on letting Xu Yuan participate.

The thought stayed here, and then he didn't delay any longer. He met everyone's gaze, smiled and spoke slowly.

"Today, our Jincheng Aircraft Design Institute will naturally announce the aerodynamic layout and appearance plan of this stealth fighter, but the speaker is the real designer of this plan."

"He is also in our venue."

It can be said that the moment Song Wencong uttered his last sentence, people from Fengtian and Xijing Aircraft Design Institute all turned their eyes to Jincheng Aircraft Design Institute.

Seems to be trying to find out the real author of the scheme.

Even Lu Dongming is like this.

No one expected that the duck-style layout that Song Wencong praised so highly was actually a design completed by someone else.

It was really unexpected.

On the other hand, at the Jincheng Aircraft Design Institute, everyone was also a little overwhelmed and full of doubts.

The main reason was that Song Wencong did a very good job of keeping the secret and did not reveal the lifting body side wing canard layout to anyone else.

Zhao Yuefeng switched his gaze from one researcher to another in the institute, and finally his eyes stopped on Xu Chongxing.

According to the analysis of the information he had, Xu Chongxing was the most qualified person to come and attend this discussion meeting. As for Xu Yuan who was behind, he had been automatically ignored.

It wasn't just Zhao Yuefeng, many people in the venue turned their eyes to Xu Chongxing.

Previously, during the development of the third-generation fighter jets, Xu Chongxing also attended the demonstration meeting.

As we all know, Xu Chongxing is from the Qinghua Institute of Fluid Mechanics, and it is indeed possible for him to design an aerodynamic layout.

Xu Chongxing felt a little amused and helpless about this. This was the first time that he was being watched by so many experts. The key was that he relied on the help of students from his own department.

However, because he knew the most about the whole thing, he managed to keep a calm expression.

There was no intention of getting up at all.

Song Wencong just watched quietly, seeming to find the current scene very interesting.

Xu Yuan knew that this moment would come sooner or later, and pretending not to see it was obviously not going to work.

So after being silent for this long, it’s time to show off your talents a little.

The thought stayed here, and without waiting for Song Wencong to speak, he slowly stood up on his own initiative.

Zhao Yuefeng noticed this scene and his subconscious reaction was to stop it, thinking that Xu Yuan did not understand the requirements of the meeting.

"What are you doing, Junior Brother? Sit down quickly."

"Junior brother..."

They were afraid that it would affect the order of the venue and bring disgrace to the Jincheng Aircraft Design Institute.

But Xu Yuan turned a deaf ear to it at this time.

He walked straight to the multimedia screen next to him, reached into his pocket, pulled out a USB flash drive and handed it to the operator.

"Please help me open the contents."

The other party obviously didn't expect anyone to be so bold. After a moment of hesitation, he still came over.

"Oh well."

He murmured a response and plugged it into the computer.

at the same time.

Including Chairman Lu Dongming, everyone's eyes were focused on Xu Yuan.

I wonder what this person, who looks like a student, is going to do.

That is to say, Xu Yuan was sitting at the Jincheng Aircraft Design Institute, otherwise he might have been kicked out.

Xu Yuan saw everyone's reactions, but remained calm.

After the slide design plan he specially made yesterday opened on the multimedia screen behind him, he took a deep breath and spoke in a strong voice.

"Hello, leaders and professors. I am Xu Yuan, a student in the undergraduate class of Qinghua University."

"Please allow me to explain the aerodynamic layout of the lifting body wing canard that I designed."

If everyone was just curious just now, then after hearing what Xu Yuan said, they were left with only shock.

It can be said that my jaw almost dropped to the ground.

It is already against the rules for undergraduate freshmen to attend a meeting of this level.

Now he even has the audacity to say that he designed the aerodynamic layout and appearance of a stealth fighter.

It's just like he's deliberately playing tricks on them.

Gao Yuhe, who had a slightly impatient temper, suddenly became stern and slammed the table angrily.

"What a joke."

"This is not your school classroom."

"We don't have time to listen to you talking about homework. Who brought you in?"

Seeing this, Xu Chongxing did not give in and spoke for Xu Yuan without any hesitation.

"Professor Gao, what you said is not right. How can you know that it is a waste of time when you haven't even listened to it yet?"

Faced with this chaotic situation, if anyone was willing to believe Xu Yuan, it would definitely be Zhao Yuefeng.

No one knew Song Wencong's attitude towards Xu Yuan better than him. He also knew that Xu Yuan was specially invited by Song Wencong this time.

Given Song Wencong's style of doing things, he would definitely not do anything he was not sure of.

Especially when he thought back to the time when Xu Yuan and Xu Chongxing came over, an idea suddenly came to his mind and he connected all the information together.

He muttered to himself in a daze.

"Could it be that Junior Brother Xu Yuan really designed the aerodynamic layout? This is too incredible."

Although this idea became clearer and clearer in my mind, it was hard to accept.

It was completely beyond my understanding.

He thought Xu Yuan was a true genius as he could study two majors at the same time and still achieve such excellent results.

This makes me feel guilty about my own misfortune.

But now it seems that what he knew was just the tip of the iceberg.

It can be said that there is no point in even comparing.

"No wonder Professor Xu and Academician Song paid so much attention to this. It turns out it was because of this reason."

"Junior Brother Xu Yuan."

"I underestimated you, brother."

After muttering to himself, he felt much more open-minded. He raised his eyes again and looked at Xu Yuan with full anticipation for the content of the plan.

Song Wencong was naturally on the same side as Xu Chongxing, and he waved his hand and replied with a smile.

"Don't get too excited, Lao Gao. Why don't you sit down and listen first?"

Lu Dongming sat in his seat, listening to everyone's discussions, and felt more and more that today's discussion would be very unusual.

He had a strong feeling that perhaps the Qinghua student in front of him would give him a surprise.

His thoughts lingered here, and he no longer remained silent, but spoke directly to define the matter.

"Our future equipment research and development cannot do without fresh blood. Let's give the newcomers a chance as Academician Song said. Everyone, please sit down and listen."

Although Gao Yuhe still had doubts about Xu Yuan, seeing that Academician Song Wencong and Chairman Lu Dongming said so, he had no choice but to sit down again and let Xu Yuan continue speaking.

"I want to hear what kind of aerodynamic layout you, a freshman, can design."

In his opinion, since Xu Yuan was a freshman at Qinghua, he must have never learned knowledge such as fluid mechanics and aerodynamics, and he probably didn't even understand advanced mathematics.

In this way, even if the shape of the aircraft is drawn, the relevant parameters are incorrect and cannot be used.

Gao Yuhe's attention was all on Xu Yuan, but he didn't notice that Huang Yunliang opposite him was staring at the multimedia screen.

I am particularly curious about the words that appear above.

“Is the lifting body wing canard aerodynamic layout a new canard aerodynamic layout?”

I'm eager to know what the effect of this combination will be.

Fortunately, Xu Yuan did not delay too much after being interrupted. He continued speaking after the meeting room quieted down.

"My design is based on Academician Song's theory of small aspect ratio, combining the lifting body, wing slats and canard in a gentle and innovative way."

"This layout unifies the contradictions between supersonic drag characteristics, low-speed maximum lift characteristics, and subsonic lift-drag characteristics."

……

"The diamond-shaped nose plus the DSI air inlet and the large delta wing with canard wing strips have created an extra-long fuselage for this stealth fighter, but it has brought about excellent supersonic cruise performance."

"And ensure that the maneuverability stability and trim capabilities are excellent enough."

"There is also a huge internal volume, ample space for electronic equipment and a large fuel capacity."

……

As Xu Yuan gave his earnest explanation, everyone in the venue gradually became immersed in the lecture.

I was completely attracted by the exquisite design of Xu Yuan's proposal.

I didn't even notice it.

Even though Gao Yuhe was extremely angry just now, his eyes now revealed a burning look.

It's like being in a dry desert and suddenly it rains heavily.

The joy on your face that comes from the heart is not something you can just fake.

He had to admit that he underestimated Xu Yuan.

"The use of lifting bodies and winglets effectively compensates for the shortcomings of the canard aerodynamic layout."

“It also further demonstrates its excellent performance.”

“Exquisite.”

“This design is so ingenious.”

After Xu Yuan finished his brief explanation and stopped, Gao Yuhe could no longer contain his excitement.

He gave this plan a very high evaluation without hesitation.

As soon as he finished speaking, he took the initiative to apologize to Xu Yuan.

"Xiao Xu, right? I was too excited just now. I apologize to you here."

"The aerodynamic layout you designed is simply perfect. It is a blessing for the country to have a talent like you."

Gao Yuhe never cared about his own face. As long as he could see this almost perfect aerodynamic layout, let alone asking him to apologize in person, there would be no problem even if he went to the other party's house in person.

Of course Xu Yuan would not put on airs at this time, and he quickly responded humbly when he heard it.

"Professor Gao, you are too kind."

When Song Wencong saw that even Gao Yuhe was impressed by the plan, the smile on his face became even wider.

Then he reached out and picked up the briefcase next to him, took out a stack of manuscripts from it and looked at Gao Yuhe and Huang Yunliang.

"This is a detailed paper manuscript written by Xu Yuan on the lifting body wing canard layout."

"You two should take a look, too."

"It's actually a manuscript?" Gao Yuhe was slightly stunned when he heard this.

He was not surprised that such an important design plan had a paper, but he did not expect that Xu Yuan wrote it all by hand.

Even in their research institute, this situation is rare.

But of course he wouldn't think too much about it at the moment, and he immediately stood up and trotted towards Song Wencong.

The same was true for Huang Yunliang on the opposite side.

In addition, other researchers from several research institutes also gathered to review the data in the manuscript.

This forced Lu Dongming to get up and leave to make room for them.

After listening to Xu Yuan's explanation, they all had a vague feeling in their hearts.

It seems that this aerodynamic layout design was tailor-made for the domestically produced stealth fighter.

No wonder Academician Song was so confident that he dared to declare that it would take only three years for the domestically-made stealth fighter to fly into the sky.

Therefore, they have to calculate whether the aerodynamic layout performance can reach the theoretical value based on the various parameters in Xu Yuan's manuscript.

This is related to whether this solution can be applied to stealth fighter jets.

At this point, Lu Dongming finally felt relieved.

I couldn't stop feeling excited inside.

When I think about the possibility that our country will have its own stealth fighter, my feelings are beyond words.

Xu Yuan naturally had absolute confidence in his plan. While a group of aircraft design experts were studying the manuscript, he calmly moved a chair, sat down and poured himself a cup of tea.

After talking for so long, I am actually a little thirsty.

-

I don’t know how much time has passed.

Then Gao Yuhe and Huang Yunliang raised their eyes and asked Xu Yuan about the problems they had discovered.

"Xu Yuan, will the use of a canard aerodynamic layout affect the stealth performance of the fighter?"

When Xu Yuan heard what Huang Yunliang said, he immediately stood up and gave his opinion without hesitation.

"Professor Huang."

"I don't think the canard layout will affect stealth performance."

"The edge scattering of the canard is very small, and because the plane intersection line between the main wing and the vertical tail of the canard-type aircraft is broken, its scattering is even smaller than that of a conventionally configured fighter."

"Take America's most advanced fighter jets for example. Their frontal Garrett air intake forms a corner reflector structure with the fuselage."

"If such a structure is not properly handled, it will cause the incoming wave to form a cavity scattering and generate a strong echo."

"Its structural flaws are real."

Huang Yunliang listened to Xu Yuan's words carefully, nodded thoughtfully, and then lay down on the table to calculate.

As for Gao Yuhe, he asked the same question as Xu Chongxing and Song Wencong.

That is, this aerodynamic layout places extremely high demands on the flight control system.

"With so many aerodynamic surfaces and at least five types of vortices, can our existing technology meet the requirements for flight control?"

Xu Yuan was very familiar with this question, and he gave his answer the next second.

"The initial design of all fighter jets is the product of compromise. The use of canard aerodynamic layout can make up for the lack of engine thrust to a certain extent."

“This is exactly what we need right now.”

"Compared with the requirements for the flight control system, sufficient power is the guarantee of the fighter."

"In addition, I also have confidence in the domestically produced flight control system."

After answering the two design experts' questions about the lifting body wing canard aerodynamic layout design, Xu Yuan finally breathed a sigh of relief and felt relaxed all over.

When Song Wencong felt that it was about right, he turned his attention to Chairman Lu Dongming again.

He continued to repeat his earlier proposal.

"I still hold the same view as before. If we are going to do it, we should make the most advanced stealth fighter."

“I hope the higher authorities can approve the project as soon as possible.”

Although the time that has passed is not long, Lu Dongming's attitude has changed drastically.

Although he did not give a direct affirmative answer, he asked for Gao Yuhe and Huang Yunliang's opinions in a meaningful way.

"Professor Gao and Professor Huang, what do you think about developing the latest generation of domestic stealth fighter jets?"

Upon hearing this, Gao Yuhe and Huang Yunliang looked at each other and then decided to agree to Academician Song Wencong's application.

"This lifting body side wing canard aerodynamic layout design is the most perfect fighter layout I have ever seen. I think it is completely feasible to use this design as the design of our latest generation of stealth fighter."

"With such a good aerodynamic layout design, it is indeed worth a bold attempt."

In fact, Lu Dongming already had an idea in his mind. Now that he saw that several aircraft design institutes had reached a consensus, he naturally would not have any other ideas.

The final decision was made immediately.

"Well."

"The Jincheng Aircraft Design Institute will develop our country's latest generation of stealth fighter jets."

"Model J-20."

"I will hold a meeting and issue the document as soon as possible."

"In addition, the project needs to be kept strictly confidential before the fighter jet's first flight."

As Lu Dongming finished speaking, Song Wencong finally showed a relieved and happy smile on his face.

After working hard for so many days, I finally promoted the project of the latest generation of stealth fighter.

I believe that when the day comes when this fighter jet actually takes off into the blue sky, the whole world will be shocked and will no longer dare to have any bad thoughts easily.

Xu Yuan was also very excited to see that the latest generation of stealth fighter jets came out ahead of schedule thanks to his efforts.

He believes that it won't be long before the domestically-produced stealth fighter will appear in the sky, giving everyone a huge surprise.

Just as I was thinking about it, I saw Xu Chongxing coming over at some point, with a look of joy on his face, and he said jokingly with a smile: "Congratulations, Xu Yuan, such a great honor is something that even I, the teacher, envy."
