The scene in the large conference room is indeed very incomprehensible.

Most of the people here are over 50 years old, and a considerable number of them are even in their 60s and 70s.

At a glance, it is simply a health care product conference for the middle-aged and elderly.

But standing at the forefront was a young man who looked to be in his early 30s, energetic and high-spirited.

Taking a photo from any angle will definitely create a great contrast.

Especially the eyes of these middle-aged and elderly people looking at Lin Mo with reverence and even worship, so this added to the atmosphere that something was wrong.

At this point,

When Lin Mo talked about finally being able to ask questions, all of them became as active and enthusiastic as primary school students.

"I'll ask first!"

"I'll come first!!"

"Teacher Lin, please let me ask a question first!"

"My question is relatively simple, no matter what, please let me ask first!"

"Let's be quiet first, even if we want to ask questions, we should all have a sequence, if you simply argue about this issue, maybe there is no result for a day and a night, I suggest this, according to age, the oldest asks first, what do you think?"

"Hehe, you are really cunning, you are the oldest present, to put it bluntly, you want to ask questions first."

"No, absolutely not, I suggest that the youngest ask first, we are in our 40s are the backbone of scientific research, and these old-timers should also let us ask questions first!"

"The old one asks first!"

"Young people ask first!"

In the big conference room, no one is willing to humble each other, and it gradually becomes like a quarrel, which is very lively.

Where did Lin Mo experience this kind of scene, he had no idea for a while, and wanted to say something to control it, but found that no one was listening to him.

Everyone became more and more unconvinced of each other, and some of the things about the old sesame seeds and rotten grains were all turned up.

Even the schools they attended can be used as arguments.

It's hilarious!

Liu Limin looked at the people around him, sighed helplessly, waved his hand at Lin Mo on the podium and said, "Comrade Lin Mo, bring headphones." ”

He pointed to the Bluetooth headset in his hand, and then to the Bluetooth headset next to Lin Mo's podium.

Lin Mo understood, picked up the earphones and put them on his left ear, and Liu Limin's voice followed: "Comrade Lin Mo, I made you smile." ”

"It's easy for intellectuals to quarrel over some issues."

"It's also a habit that everyone spends all year round in a closed place like a military factory, and they can move their bodies when they are noisy."

A drop of cold sweat was about to run down Lin Mo's forehead.

He had just fallen in love with the environment in the military factory, and even fantasized that it would be a good thing to stay here for a while, but he never expected that reality would soon give him a hammer.

Boy

It's messy enough, too.

Lin Mo calmed down, lowered his voice and asked, "Old Liu, what do you think you should do in this situation now?" ”

"These old men haven't slept all night, and if they continue to be so noisy now, if anyone's blood pressure can't be controlled, it will become a big problem."

The most taboo thing for the elderly is to be emotional, Lin Mo's grandfather was emotionally unstable because of his love for temper, and finally got sick when he got old, and finally his life in his later years was not happy.

"It's okay, they're not crispy college students in society, they're used to arguing." Liu Limin didn't care too much about this matter, and lowered his voice to remind, "I just want to trouble you not to speak freely in the future, even if you want to ask a question, you must call the other party by name directly." ”

"It's like a teacher's roll call!"

"Old children, old children, you can't treat them as young people, just treat them as children."

Will it work?

Lin Mo was also skeptical of Liu Limin's statement, after all, he had never experienced such a scene.

But now in this situation, it can only be treated as a dead horse as a live horse, try it, anyway, there is nothing else to do now, and there is no harm in trying.

He looked around, took a deep breath, pressed the megaphone on the podium and said, "That. Please be quiet. ”

"If you really want to quarrel, then you quarrel first, I'll go and rest for a while, and I'll come back when you're done, and we'll continue to talk."

"Seriously, I'm really tired after a whole day on the plane!"

Lin Mo didn't talk nonsense with them, and after saying this, he turned around and prepared to walk towards the audience.

It's also a two-handed preparation.

If everyone can stop arguing, then Lin Mo will continue to explain some issues to them, if they are really unwilling to stop the discussion, then Lin Mo will definitely leave the conference room first.

He had already seen that high-quality scientists were nothing like what he had in mind.

A significant number of these bigwigs have paranoid symptoms, like barrels of gunpowder, which can explode at the slightest bit.

And when the experts and scholars on the scene saw that Lin Mo really wanted to leave, their expressions became nervous one by one.

They waited all night, just to let Lin Mo answer the question in their hearts, if Lin Mo really left, they were afraid that they wouldn't even sleep well during the day today.

That would be so torturous!

Under the influence of this mentality, everyone gradually quieted down, and began to quarrel with each other to stop each other from arguing.

"Okay, don't make trouble, everyone is a person with status, can you have some quality?"

"Who is not qualified? If you want to talk about lack of quality, who can compare with you people in Qingbei, who thinks that they are superior to others."

"Alright, shut up!"

"Are you going to quarrel and go out and quarrel?"

"I don't know where your superiority comes from!"

"Hehe, we are cattle in Qingbei, and how much science and technology is our school."

"Shut up, it's okay to fool others, don't even deceive yourself, just give the resources of your Qingbei to any school, and the results you can achieve will not be worse than your Qingbei, right?"

While there were sporadic people arguing, the large conference room was indeed getting quieter.

After waiting for more than a minute, the large conference room finally returned to its original silence.

Liu Limin quietly breathed a sigh of relief, secretly gave Lin Mo a thumbs up, and said in the headset, "Comrade Lin Mo, it's really hard for you." ”

"When I'm done with these things, I'll treat you to dinner alone."

Lin Mo was not interested in eating or not, even if it was the absolute top big man in Daxia who invited him to dinner, that would not make Lin Mo much interested.

He has been in contact with too many big people, and he no longer has the feeling he had at the beginning.

His gaze was calm, from left to right, sweeping over the faces of most of the bigwigs, and finally waited until he saw the first row before he spoke, "I understand everyone's work on weekdays, and I also think that arguing with each other for ideals is a happy thing." ”

"But after all, we have something to do today, let's talk about the drawings first, and after this matter is over, if you have anything else to say, then you can talk freely!"

"That. Let everyone raise their hands to speak. ”

"After all, we are in the Imperial Capital No. 1 Military Factory, so I think this first opportunity to ask questions is to hand it over to the director of the Imperial Capital No. 1 Military Factory, what do you think?"

Lin Mo was originally going to let the three domestic aero engine giants speak, but after thinking about it carefully, it was indeed the director of the First Military Factory who was more suitable.

At least if he speaks first, no one will have too many opinions.

Although these literati are not easy to get along with, they still have some reasoning after all, and as long as they can find a reason to convince everyone, they are still more willing to listen.

"Yes, I think Comrade Lin Mo is very right!"

"That's it, Director Hu, the opportunity has been given to you, I hope you can ask some more constructive questions!"

"Everyone, stop arguing, and don't speak casually, otherwise no one will be able to ask questions in the end, and it will be a waste of the original intention of this exchange meeting!"

"I'm okay with that."

Some respected old men expressed their thoughts one after another, and basically they didn't have much opinion on Director Hu's question.

But Director Hu himself never imagined that he would be the first to speak.

Fortunately, he was not an inkblot character, so he immediately stood up from his chair, thinking about his respectful attitude towards the school leaders when he was in college, and opened the small notebook he had in his hand.

It records a lot of difficulties about vector engine drawings, as well as some incomprehensible points.

After he got up, he said, "Comrade Lin Mo, as we all know, the manufacturing process of the tail nozzle is difficult, the air wave pressure value of the tail nozzle is large, and the parts need to be compact and withstand the pressure very large, so the material aspect is the biggest difficulty of the vector engine. ”

"In your drawings, I think all aspects are excellent, especially your understanding of the flight control system is very good, even I, an expert who claims to be an engine academician, am ashamed of myself."

"Then I would like to ask you on behalf of myself and my colleagues here."

"What materials are you going to use to make the nozzle of the vector engine?"

This question is also a concern of many people present, and many people secretly lamented that the question raised by Director Hu is very accurate.

At least I didn't ask some of the more mentally retarded questions.

Lin Mo didn't know what questions everyone was going to ask him before, so he could only hear the questions and then input them into the intelligence system in his mind, and then retrieve the answers.

The process is very fast.

And the system's explanation of various issues is also very in place, what Lin Mo needs to do is just read from the book.

He paused for a moment, pretending to be thinking, and then spoke after about a few minutes, "In vector control technology, vector nozzle adjustment and seal castings are very important accessories. ”

"The use of these parts and materials determines whether the vector engine can be successfully started in the end and withstand the ultra-high temperature generated by the engine when burning."

"As far as I know, everyone used to use composite materials as sealing materials and the main materials of vector engines, but there is no problem with this idea."

"The reason why you didn't succeed is because the material you chose is not quite right, and after my countless experiments, as well as some experience in other countries, nickel-aluminum alloy material is the most suitable material for vector engines!"

"Not only is the flame generated by the engine impacting the vector nozzle to withstand high temperatures when the vector nozzle is deflected, but it also has a strong oxidation resistance, so that the vector engine does not need to be maintained all the time and does not need to be replaced every time it flies."

Nickel-aluminum alloy material?

Hearing the materials mentioned by Lin Mo, many materials science experts present already frowned.

They have been dealing with various materials all their lives, and of course they know what nickel-aluminum alloy materials are, and they also know that this material has ultra-high toughness and strength, as well as anti-oxidation properties.

In fact, when they were doing experiments, they also used this material as a raw material for their experiments.

However, there is a problem that is difficult to solve, that is, the hardness of nickel-aluminum alloy materials is too strong, and it is easy to break if it is too rigid.

If it breaks in the air, it will have unimaginable consequences for the fighter.

It can be a crash or the death of the pilot.

Fighter pilots are an absolutely important strategic resource for major countries, and the cost of training a fighter pilot in most countries in the world is far greater than the equivalent of the pilot's own weight.

So until now, no one has dared to use nickel-aluminum alloy material as the main body.

Lin Mo knew what was going on in their hearts, because it had already been mentioned in the information of the intelligence system.

Without waiting for Director Hu to ask, Lin Mo continued, "Aluminum-nickel alloys are mainly composed of aluminum, nickel, cobalt and other elements. Among them, the control of the percentage of aluminum-nickel alloy can directly affect the material properties of the alloy. ”

"In the past, the largest amount of aluminum production method was around 60%, and the lowest was not lower than 50%, but have you ever thought that the aluminum content can be further reduced, such as to less than 20%."

Ha?

Reduced to less than 20%?

Will it be possible to mold in that case?

And they feel that no matter how they look at it, it is absolutely impossible to achieve, and they all think that such an idea is too crazy.

Director Hu asked, "But if aluminum is reduced to 20%, what material should be used as a supplement?" You can't have to make nickel 80%, right? Then there is no way to make a material with the right strength. ”

To be honest, if they hadn't seen Lin Mo's drawings before, they would have thought that Lin Mo was a complete liar who didn't know a little about material science at all.

20% aluminum plus 80% nickel?

What kind of nonsense material ratio is this?

If you think of such a ratio, it would be impossible to make any materials that can be used!
