Academician Qiao covered his heart.

Huang Qihui was also taken aback!

Cao Wansheng, Qian Gaoxuan, and other 8-level and 9-level senior engineers in the processing center are all treasures that have been accumulated by the 606 Institute with great difficulty.

Seeing Liu Feng digging a trap and burying the machine so naked, he almost wrote on his face, you all follow me!

If you really want to succeed in it, then do you still make it?!

Even if Liu Feng's hope of winning in the end is 1%, it is impossible for them to accept this kind of bet, this guy, after all, is Professor Liu!

Huang Qihui: "That, Professor Liu, it's not necessary, it's really not necessary......"

Academician Qiao: "Brother Cao, Brother Qian, everyone has a friendly discussion, don't be impulsive, don't be impulsive......"

Both of them tried their best, however, they couldn't resist the hard temper of these masters!

"Bet on it!"

"Who's afraid of whom!"

"If you win, I'll resign directly and work for you for three years!"

The teachers were also angered by Liu Feng.

"Come on, if you can't make a sense, you can stay here and give us a 5-year apprentice!"

Academician Qiao: "......"

Huang Qihui: "......"

Seeing this, Liu Feng's face already showed a wicked smile like a little fox, could he not be happy to catch such a big fish so easily?

Class 9 fitter, Class 9 lathe, Class 9 miller...... With such a large number of top engineers, Lao Tzu can even make a nuclear submarine by himself!

didn't pay attention to President Huang Da.

"Talk about it, maybe you won't believe it, so let's do it, you should have a metal material laboratory here, lend me two hours, bring me your knife head, well, prepare a few more materials for me, and in two hours, we'll see!"

……

In the quiet materials laboratory, there are only two people, Liu Feng and Academician Chen Xuedong.

Originally, Liu Feng could do it by himself, but Academician Chen had to come over to help him, and he couldn't afford to brush off the kindness of others, so he easily arranged Chen Xuedong to be his assistant.

Well, the academician-level boss served him tea and poured water, and there was no one left.

"Here, you want green tea!"

Bringing up the green tea that Liu Feng needed, Chen Xuedong really couldn't stand this weird atmosphere, but when the words came to his lips, he didn't know where to start.

"If you want to ask anything, just say it, it's weird and uncomfortable!"

Put several prepared materials into the arc crucible specially used to smelt high-temperature metals, thought about it, took out the knife head again, and Liu Feng, who was about to put it inside, glanced at Chen Xuedong and said.

"You, how sure are you?"

"No, you should ask me if I'm 100% sure!"

Chen Xuedong: "......"

"Well, in fact, from the moment they agreed, the result was already doomed!"

Liu Feng glanced up at him, and continued to be busy with the things at hand, explaining while busy,

"They're just too confident, too much in their experience...... In short, if it is too absolute, it is superstition. If others don't believe me, can you still not believe me?

Chen Xuedong shook his head helplessly: "Forget it, although I don't know where you got your confidence, but ...... Hey, what are you doing here?"

Seeing that Liu Feng threw the knife head directly into several materials that had melted together, Chen Xuedong's face was full of curiosity.

"Add some spice to this knife!"

"What do you mean......"

"That's right, that's what you see, I'm going to add a few special alloys to this bit to improve the performance!"

"It's that simple?"

"What do you think?"

"But why don't you melt the head and add these materials to it, but the other way around?"

"Oh no, why didn't you say it earlier, and let it go the other way!"

Chen Xuedong: "......"

"An-la-a-la, it's actually the same!"

Chen Xuedong: "......"

I almost didn't get to death!

Forget it, he can't help much anyway, so he won't stay here to get in the way.

After all, people are masters of materials, although this guy has always been mysterious and secretive in doing things, but the results can be surprisingly correct every time, people have such skills, what can you do?

After Academician Chen stepped aside, Liu Feng finally breathed a sigh of relief.

Although he was sure that even if this big guy was here, he wouldn't be able to see anything, but what if?

On the surface, it looks like he's adding special material to the bit, well, and in fact he does...... It's just that if you just melt a few materials and roll the cutter head in a circle, it's too shocking, right?

It is better to be able to grasp the particles of the microscopic world and keep it in your own mind forever......

Materials are king.

Even the turning tool of the five-axis linkage CNC machine tool still follows this principle.

In fact, the reason why the tolerances of the processed materials do not meet the requirements is precisely because of the cutter head material, of course, it can also be said to be the reason for the "carbon sail" material.

In the process of receptor processing, between the cutter head and the acceptor, the volume, density, tension, specific surface area, is changing all the time, and this change, in fact, does not appear when processing other things, but only this "carbon sail" material will be affected by such a huge impact, and after the end of processing, in addition to a small amount of wear, the material change of the cutter head can return to normal!

This is why the masters can't find the problem, which is why Liu Feng asked whether the domestic technology can monitor these changes in real time!

Anyway, the final result is as simple as that, but only Liu Feng, who has opened the hanging, can find out!

found the problem, and then, it was difficult for him, a master of materials, to solve the problem in a targeted manner.

Simply changing the properties of the cutter head, and then ensuring that the impact of the cutter head on the "carbon sail" is within a reasonable range during the machining process, is much simpler than studying what antimatter pulsed energy engine is......

Well, such an ability, if he joins the machine tool industry, he is fully confident that directly from the material aspect, the quality of the machine tool will be improved to an incredible level, what kind of material needs what kind of cutter head, he can ensure a perfect match in minutes, so what machining accuracy, what machine tool life and the like, is not a piece of cake?

That is, in terms of efficiency, it is really not what he is good at, so he can't do anything about it.

That's right, your European and M machining centers have advantages in dynamic and thermal comprehensive compensation technology, and can also monitor the changes of cutter heads and materials in real time, but we have materials, which directly and fundamentally solves the problem that materials affect the machining accuracy of cutter heads.

What, your machine tools have good reliability and a bit life of up to 10,000 hours?

Hehe.

We have new materials, and when processing the receptor, there will be few elastic deformations, and the reliability is not much stronger than yours?

As for lifespan, is 20,000 hours enough? Not enough, what about 50,000 hours?

It's as simple and crude!

Of course, I'm afraid that Liu Feng is the only one in this world who can do this, after all, who can let him hang up?

……

Two hours is just a nap.

Soon, Liu Feng walked out of the laboratory.

"Cao Gong, don't you mind doing it again, right? Well, use this cutter head. ”

Seeing the turning knife handed over by Liu Feng, Cao Wansheng really didn't see it, what was the difference between this and the one he gave Liu Feng before?

The people around them were the same, although they guessed what Liu Feng might do, but they did it so easily?

Is that really okay?

Perhaps seeing their doubts, Liu Feng explained simply: "I added some material to this turning tool, well, the specifications should be similar to the original turning tool, and it should be able to solve the problem." ”

"Are you sure it's okay? Don't blame us for the problem if it doesn't work out then?"

Cao Wansheng confirmed again and again.

"Don't worry, there won't be any problems!" Liu Feng said with a smile, "If it doesn't work out this time, I'll admit defeat directly!"

Well, what a strong self-confidence!

Although he didn't know where this guy got the confidence, Cao Wansheng didn't care so much, and in the expectant eyes of the old partners around him, he directly installed the turning tool on the machine tool, and then adjusted the instrument a little, and then started again.

"Get on the material!"

……

It's still a pleasing operation, and it's still a master-level stable level.

When the turning tool finished the first lap, Liu Feng already knew, this time, it was stable!

I found a place to sit down, and while crossing Erlang's legs, I was digging a lunch box into my mouth.

You say it's not annoying, these guys have all had lunch, and we're still experimenting with sleep and food, hum!

However, except for this product, almost everyone stared intently at the display screen of the CNC machine tool, and the atmosphere did not dare to come out.

It's just that when they accidentally saw that Liu Feng could still eat and drink well, they couldn't help but secretly admire this guy for being calm.

At this time, you are not nervous at all?

Without making everyone wait long, the "carbon sail" with an oval curved surface was once again "complete" processed.

"How, what was the result?"

A group of old fellows immediately gathered around him, asking how he felt.

Cao Wansheng clapped his palms.

"How do I know if it's qualified or not? It's just that there is no unusual feeling, wait for the result!"

As he spoke, he glanced at Liu Feng, and then directly asked the QC staff to bring the finished product over for inspection.

Another long wait......

However, the outcome was already predestined.

Sure enough, an hour later.

"Impossible, absolutely impossible!"

Cao Wansheng pinched the test report in his hand, looking like he was hell.

Others also rushed in.

"Is the product qualified?"

"Hell!"

"It's incredible!"

"How!"

In the midst of the surprise, a group of people stared at the young man who was drinking tea next to him with complicated expressions, what kind of magic did he use?

"Actually, the principle is very simple," put the water cup on the table, Liu Feng stood up leisurely, "Didn't I ask you before, how is our machine tool sensing technology......?"

"That's it!"

After listening to Liu Feng's detailed explanation, and with a realistic sample in front of him, Cao Wansheng was speechless for a long time, and the other experts who bet were also speechless for a long time:

After a long time, this one sighed: "We admit defeat......"

"Ahem," seeing that these guys' pants were all lost, Academician Qiao's heart was like a pinprick, it hurt!

Quickly stood up, even his body trembled slightly,

"Well, Professor Liu, can we discuss something alone......

The spring breeze is proud!

……

Just when the prototype of the pulsed energy engine of the Power Research Institute was about to be assembled, on the other side, in the Qinling Mountains, deep in the mountains.

Under the leadership of Chief Engineer Xie Pengyi, a group of technicians are also doing a final comprehensive inspection of the high-thrust rocket engine test bench.

No, in fact, it has long since been renamed the pulsed energy engine test bench.

The design and manufacturing process of developing a high-thrust engine is a difficult task, but without a suitable test bench, the manufactured engine cannot be tested for reliability and cannot be finalized.

In order to test the pulsed energy engine, the high-level directly allocated the test bench used to test the rocket engine to Liu Feng, which made the Aerospace Science and Industry Group feel distressed for a while, after all, there are only two such test benches in the entire Huaguo, and Qinling is still the latest!

In this regard, Xie Pengyi did not feel any distress.

Isn't a rocket engine a test, but isn't a pulsed energy engine also a test?

The only thing that makes him feel sorry is that this test bench has just been built for less than two years, because of the need to test the pulse energy engine, many new equipment and new facilities have been overhauled, which is a waste.

In fact, the previous rocket test bench is mainly composed of liquid oxygen supply subsystem and liquid hydrogen supply subsystem, these two systems are the power source of the rocket engine, each subsystem includes a pressurization system, a hydraulic circuit system, a blowing system and an exhaust system;

It's a pity, of course.

This time, in order to ensure that nothing goes wrong, Xie Pengyi took out a 200% cautious attitude, divided the investigators into two teams, and cross-checked the two systems.

"Have you all checked it out?"

Staff: "It's all checked!"

Xie Pengyi nodded: "Hand over all the problems you checked, if one party finds a problem that the other party has not found, then congratulations, and you should also thank each other and generously give the reward to yourself." Of course, rewards and punishments are not the goal, just to ensure that the project is foolproof......"

Staff A: "Director, our group didn't find any problems, everything is normal. ”

Staff member B: "Director, our second group didn't find any problems......

Xie Pengyi: "......"

"Is it really all checked?whether the interface of each connection line is stable, whether the error of the sensor is within the allowable range, and the underground cooling device...... Are you all right?"

Very uncertain.

The technicians on both sides glanced at each other, both breathed a sigh of relief, and nodded quite affirmatively: "It's all checked!

"Whew~" Xie Pengyi also looked relieved, "Okay, you guys go down and rest first." Three groups, you follow me and check again. ”

“……”

“……”

“……”

Although such a tedious examination was quite torturous, no one expressed dissatisfaction.

What they tested, at worst, is related to the safety and stability of spacecraft, but at worst, it is related to the future of the country and the nation!

Any slight omission may cause serious consequences such as aircraft crash and death, so we have to let them be cautious and cautious.

And at this time, "Mr. Almost" is naturally absolutely not allowed, almost, almost, almost a crime!

The investigation lasted a week.

Finally, the day before the New Year, they completed all the inspections.

And at this time, Xie Pengyi finally dialed out the number as if relieved......

"Professor Liu, we're ready!"
