Unlike most of the engineers in the hospital, Du Songtao belongs to the kind of people who have to be coaxed up and down, for fear that he will not be served well, and if he is unhappy, he will change to a declassification position, and after two years of declassification, he will go to private aerospace as a partner.

On the one hand, he has no ambition for power, and he does not squeeze into that circle at all, and whoever likes to be the leader should be.

On the other hand, his attainments in carrier rockets, aerospace engineering, and especially satellite technology have brazenly reached the level of leading the entire system.

In short, a person who obviously has the strength to become a learner, but does not climb up, plays his own game.

As a result, the upper echelons can neither guide him by profit nor control him with their wrists.

He can only do whatever he wants, and he can't do anything if he doesn't want to.

Such a person is destined to fail to become a scholar, and he has no motivation to cultivate a demon.

In the end, he became a terrifying, gnashing of teeth but an existence that he couldn't hate-

Hooligans.

The so-called rogue is arrogant, and you can't do anything about him.

And the students are also divided into successful students and failed students.

Of course, Du Songtao belongs to the category of success, although he is a wave, but he will do it when he should do the right thing, but he also does a very good job, just like a very smart and excellent bad boy in the class but always naughty and mischievous, so that the teacher loves and hates, and finally scolds him while sending him a three-good student.

If you break down the counterexample, you will probably be classified as a failure, although you are strong, but you can't do anything serious, and you are gradually marginalized and become a dispensable figure, just because he has a good academic ability, so he is left with a position.

As for the attitude of the hooligans, Li Zheng two years ago was opposed, thinking that they wasted their talents and time and did not study hard.

But today he has gradually turned to neutrality, everyone has their own life and choices, and they should not be kidnapped by personal value standards, as long as they can support themselves, do not do things that violate the law and discipline, and do not degenerate into bandits and thieves, how they play is their freedom.

Back in front of him, Du Songtao parachuted into the seventeenth institute, this is also an act full of rogue style, although the time is limited, he must go back when 927 enters the assembly stage, but to temporarily let go of this level of character, the leaders of the four academies seem to have eaten a lot of rogue means.

After gaining Zhu Mingyue's trust, Li Zheng and Lin Yujing naturally became members of the "Jun Songtao Airborne Division".

But in fact, everyone knows that such a professional field and such a complex problem are unlikely to be solved by a limited number of generals, not to mention that none of the three are engine majors.

Even if someone really believes in them and thinks they can make a difference, it's hard to say.

After all, in such a group of veteran engineers with more than ten years of seniority, it takes a lot of courage and a lot of cheekiness to say things like "high school students can solve the problems in front of us".

Some people even think that Zhao Zhenhua has gone crazy, rushed to the doctor in a hurry, and actually bet on the two children at the end of the road, this behavior is comparable to the faint king of the end of the empire.

However, everyone's attitude towards Li Zheng and Lin Yujing is still very tolerant, these two children are not wrong, although they have enough capital, they do not show any arrogance, they bow and nod and shout teacher when they meet people, which is still very pleasing.

In short, most people still believe that if there is a solution, it must be produced within the team, and it will never be these few people, they are all very good people, but their presence here will not do anything real except to prove the madness of a very few leaders.

The good news is that Li Zheng has an office.

Although it is a shared office, it is cool after all, after all, with a large bookcase, you can put a lot of columns.

This is also stained with the light of Jun Songtao, his level is always not good in the public office area, so Zhu Mingyue arranged a large shared office for the airborne division to land.

At four o'clock, the three of them set up their own outfits, adjusted their computers, and finally sat down.

Jun Songtao dominates the window, while Li Zheng and Lin Yujing are lined up on the other side, which is basically the layout of a miniature studio.

After the arrangement, Li Zheng naturally began to dismantle the partition between him and Lin Yujing.

Lin Yujing hurriedly held it down, "Keep it!"

"It's so tiring to talk that I have to lean back. ”

"No, keep it, I want to have my own space. ”

"Will you still be able to sleep in separate beds when you get married in the future?"

"Don't ...... Don't digress from the topic, you're changing concepts. ”

"Alas......" Li Zheng turned to Du Songtao, "Help me say something." ”

"You two settle your own business. Du Songtao was cross-legged and glanced at the preliminary fault report, "It's more like the accident of the god of fire......

Li Zheng hurriedly put down the partition and came to Du Songtao's side.

"Tell me more about it?"

"It is the hydrogen and oxygen engine model engaged in the nineties of the last century in Europe, there have been a lot of things before and after, Vulcan 1 and Vulcan 2 engines, have experienced several mission failures, before Huang Er failed, I just suspect that the failure is somewhat similar to Vulcan, read the current information, basically certain. Du Songtao put down the material and pursed his lips and said, "I just talked to Zhu Mingyue, and they are indeed referring to the experience of the God of Fire, the problem is that the information revealed is very limited, and it is difficult to distinguish the truth from the false, which is likely to be misleading." ”

Li Zheng frowned and said: "That is to say, the cause of the accident and the direction of improvement disclosed by the Vulcan may be a smoke bomb, and it has not touched the core at all?"

"Yes, so you can't ignore the god of fire, and you can't just look at the god of fire. Du Songtao hooked his hand and said, "Who's that, come over too, I'm going to explain my work." ”

"It's Lin Yujing. Lin Yujing picked up the notebook, pulled the chair and walked to the opposite side of Jun Songtao.

"Eh?" Du Songtao smiled, "Look, our names are quite opposite, I'm 37 this year, what about you?"

"Woooooo

Du Songtao helplessly turned to look at Li Zheng: "Is she like this with anyone......

"Hmm...... She should think you're one of her own. Li Zheng also pulled a chair and nodded, "This is a gesture of affection." ”

"Then I'll just believe it. Du Songtao smiled at Lin Yujing and said, "Your mother is also a figure I admire, as the chief designer of Huang Er, she must not only be knowledgeable, but also courageous, anyway, I can't withstand this pressure, if I change me, I will pick those jobs that have become very amazing, and they will not be too criticized if they are not successful." ”

"Hmm......" Lin Yu froze for a moment, and then nodded, "I should be ...... too"

"Beautiful, we're all the way. Du Songtao smiled, "But now the situation is different, I don't want the Seeking Knowledge No. 1 to continue to be postponed, plus I want to struggle for a while, so I came here, what about you?"

"For learning. Li Zheng nodded immediately.

"For the sake of ...... For the sake of ......" Lin Yujing scratched her head, a little messy, and finally had to reply, "Although I really want to see Huang Er turn the tide, I was actually pulled by a hard pull...... I didn't expect anything to be done. ”

"You're right. Du Songtao smiled with satisfaction, "I don't expect myself to play any role, like Li Zheng, I think I can do something is a hole in my brain." But that doesn't stop us from trying, remember our principles?—— pick the ones that are amazing, and they won't be too criticized if they don't work. ”

"Hmm. Lin Yujing nodded convincingly, "Well, all the way." ”

"What about you?" Du Songtao turned to look at Li Zheng, "Do you accept this attitude?"

"Reluctantly accept it. Li Zheng nodded and said, "The basic task is to learn, and I can do as much as I can on top of this, if Huang Er still does not succeed in launching at the end of the internship period, I will continue to help in a part-time way." ”

"Okay, then the attitude is unified, let's talk about the rules. Du Songtao raised his hand and said, "First, get off work on time at six o'clock in the evening, and whoever wants to work overtime will move out of this office." ”

"Support!" Lin Yujing said quickly.

"Hush. Li Zheng only turned his head sideways.

Jun Songtao continued.

"Second, don't bother me with work during non-working hours, if it's drinking, chatting, or going to some party, of course I'm supportive. ”

"Third, don't be lazy during working hours, work hard every minute, don't do the stupid thing of staying up late and then making up for sleep during the day, I just need a clear brain and abundant inspiration here, and you feel that you don't have these two things and go home to rest. ”

"Okay, the rules are over, and here's the work policy. ”

"We have limited manpower and only do head work. ”

"We have researched and excavated inspiration and reliable clues for failures. ”

"And then throw these things at the people outside, and they will naturally desperately do the follow-up work. ”

"We use this time to find the next inspiration. ”

"We maintain this cycle until we reach a reliable conclusion and determine what works. ”

"You may think that this approach is unfair to people on the outside, but we are half laymen, and inspiration and interdisciplinary perspectives are our strengths, and we need to play to those strengths, rather than get bogged down in redundant work. ”

"So, start now, find your inspiration and try to dig something out. ”

After being looked at by the two for a long time, Du Songtao waved his hand again: "I'm done, let's go." ”

Li Zheng scratched his head a little confused: "Don't you have any specific instructions?"

"Didn't I instruct me?" Du Songtao nodded, "Find inspiration, dig something out, the three of us, no matter who has any ideas and discoveries, discuss them at any time, and if necessary, cooperate in research, otherwise we are free to explore." ”

"Roger. Lin Yujing immediately got up, "All the way!"

Jun Songtao smiled and waved his hand: "Remember to get off work at six o'clock, don't force me to urge." ”

Speaking of which, Lin Yujing was more confident than studying rockets, and her face was full of determination: "Make sure that every second is not bad." ”

Li Zheng shook his head, got up and muttered, "My thinking is not driven by inspiration, but to study data and algorithms." ”

"Whatever you want, just get off work at six o'clock. ”

"Seven o'clock, have a bite to eat and then go." ”

"No, I can't. ”

"Why are you so strict?"

"It's that strict. ”

"Wouldn't you just work overtime......

Li Zheng returned to his workstation in a huff.

What greeted him was Lin Yujing's comfortable face.

It was as if it was written on her face - finally someone can cure you!

......

Since working with Juniper, the pace of work has changed significantly.

There is no pressure, no deadline, and once in a while, whoever has inspiration will talk together, otherwise they will do their own thing.

After two weeks of mixing like this......

Sure enough, nothing has progressed!

During this period, Li Zheng also took three days off, went to Hengshui to get a biological gold medal and came back, the seventh result in the country, and also created the worst record since he competed.

However, in this process, Li Zheng's determination was not dissipated by Du Songtao's work style, he still insisted on giving full play to his limited strengths, hoping to find something in the test data in a mathematical way.

If it weren't for the confidentiality requirements, he would have taken the mathematical model to someone like Jie Qiqi for advice.

In this process, he also tried to cooperate with the people of the 11th Institute again, but the focus of the other party's work had already shifted, and the matter at hand was already very busy, and it was unlikely that he would put more energy into Li Zheng's topic.

Unlike the tepid of the "airborne division", the opinion of the YF-87 team has been divided into two fierce factions.

First, replace the material and strengthen the entire shaft system.

Although it is not possible to diagnose the cause with certainty, since the fault phenomenon is a shaft break, it is natural to strengthen this weak link.

The cost of this is a significant increase in engine weight and a 5% to 15% reduction in the payload of the rocket, and while it is not 100% sure that the problem will be solved, this solution is intuitive and fast, and it can use the factory's capacity before the 927 starts construction, and complete the test run by the end of the year.

Second, the entire engine was redesigned.

As Du Songtao said, the launch vehicle is a complex and sophisticated set of engineering.

In many cases, finding faults and correcting them is far more costly than redesigning from scratch.

If you can't make a thorough improvement in a short period of time, start over.

This kind of inexplicable low-probability failure cannot occur twice in a row.

It's like rolling a random number from 1 to 100, 1 to 98 means a successful launch, and 99 and 100 mean a failure.

The first time, it was very unlucky, and I won 99.

Then do it again, it is impossible to be unlucky in a row.

The advantage of this solution is that it is more likely to eradicate the disease, and it opens up more space for Huang Er to develop in the long run.

The disadvantage is also obvious, the redesign of the engine will not be completed within a year, and adopting this plan is equivalent to publicly declaring that Huang Er will give way to the 927.

The matter of China's large-scale hydrogen-oxygen engine is really a long-term consideration.

These two sets of plans naturally mentioned Zhao Zhenhua's desk.

At this time, Zhao Zhenhua had already dyed his hair freshly, and his white hair was gone.

But in contrast to this black hair, his face looks even older.

"Mingyue...... Seventeen have not experienced anything...... Can't you get through this hurdle?" Zhao Zhenhua clutched the report, his eyes were a little distracted, "Reducing such a large effective carrying load, does the meaning of Huang Er still exist? Isn't the purpose of hydrogen and oxygen to pursue a more extreme load? This is equivalent to a person who takes the initiative to reduce his weight in order to run faster, but you find that his bones have also become brittle, so you put two layers of steel plates on his legs, what's the point?"

"Prove that he can still run. Zhu Mingyue nodded heavily, "Run up first, don't fall down, and then hurry up to study the problem." ”

"Then aren't we the sinners who delay the development of aerospace?" Zhao Zhenhua held up the report weakly, stared at Zhu Mingyue and said, "With such a foolish plan, fighting for more resources and tinkering, it is indeed possible to protect ourselves in a short period of time, but I can't say that this thing is stronger than 927." ”

"Then there's only one other option. Zhu Mingyue sighed, "Give up the present and redesign." ”

"Alas......" Zhao Zhenhua put down the report, leaned back in his chair, and stared at the sky for a long time, "How are they doing research?"

"Several ideas have been proposed, but there is a lack of valid evidence to carry out research, and even if there is valid evidence, it may be difficult to find a solution in a short period of time. ”

"No, this is not Li Zheng's style...... Zhao Zhenhua straightened up again, "Has Li Zheng made any progress?"

"As far as I know, he's still working on data and algorithms, but he's probably pushed his limits to what he can do. Zhu Mingyue shook his head and said, "He proposed to share information and cooperate with the laboratory of Harbin Institute of Technology, but the stakes are very high, and I have not approved it yet." ”

"Why?" Zhao Zhenhua glared, "Didn't I say that I should try to cooperate?"

"Secretary...... I...... I'll say something a little offensive......" Zhu Mingyue said in a tangled way, "I hope you are sober...... Now that this is the case, we are again at risk of leaks...... Do these...... It's not wise to do these things that make the outside world look ridiculous. ”

"Okay, I got it. Zhao Zhenhua raised his arm and said, "Let him apply, don't go through the troubleshooting channel of your six academies, take the scientific research cooperation channel, take it, I will approve it." ”

"Secretary......" Zhu Ming wanted to cry without tears, "someone is already talking...... Say you're mentally struggling...... He even sent two ......"

"Let them go!" Zhao Zhenhua said angrily, "If we can afford to hire a top data analyst, what the hell will I expect two middle school students?! Such a project is not allowed to cooperate with a data analysis company, what do you want me to do?! Times are changing, Ming Yue, we must embrace these new technologies, if we can't invite top talents, then people like Li Zheng are the biggest bodhisattvas. He did him, and he didn't occupy your resources, and you are afraid of an egg if you cooperate with Harbin Institute of Technology!"

“..................”

After a long silence, Zhao Zhenhua cut his hair and calmed himself down.

"The 927 is already in the design phase......"

"Lao Liang's vision is really poisonous, with Shen Tinglan here, this process won't take too long......"

"I'm sorry, Ming Yue, it's indeed possible to temporarily get through the current difficulties, but this belongs to hiding the world and the sea for my own interests, if I use this plan to fool the leader and hide the world, I am really crazy. ”

"I admit that there is an element of gambling in sending Li Zheng there. ”

"But there's really not much I can bet on. ”

"If they scold me, scold me, anyway, I owe a lot of scolding in my life, and I will be scolded for a few years, and I don't lose money. ”

"I see. Zhu Mingyue nodded, "I'll help Li Zheng draft the report when I go back." ”

"It's hard work, this matter is on my head, take the channel of scientific research cooperation, and your six academies don't have to be responsible. Zhao Zhenhua went on to say, "At this stage, the road of hitting the steel plate cannot be taken, and it is too late to start over." I can only hurry up and continue to look for the root of the disease, of course, this is not indefinite, at the latest in December, the factory will move for 927, if you can't find the root cause at that time, you can start again......"

"It's ...... 'we', let's start all over again. Zhu Mingyue swallowed and foamed.

"Huh. Zhao Zhenhua smiled, "Don't worry, there must be no me at that time." ”

......

That night, Li Zheng secretly violated the rules.

He didn't leave work at 6 o'clock.

Instead, he shrunk in the corner of the restaurant, worked secretly, and worked until 9 o'clock, still very excited.

The approval of the cooperation with Harbin Institute of Technology and the cooperation with the strongest laboratory in the field of engineering computing in China must be exciting.

To this end, he has to race against time to make a meeting gift, fully express his limited achievements during this period, reduce the cost of understanding Harbin Institute of Technology, and conduct in-depth research as soon as possible.

During this time, of course, Du Songtao and Lin Yujing were not idle, but they started to find inspiration in the field of mechanical engineering, which is not their specialty, and even if they put forward some ideas, it is difficult to continue.

Of course, they didn't have such a strong sense of purpose as Li Zheng, and coming here was just a venture in itself.

In the midst of the struggle, a voice came.

"Hi ......"

"Let's go......" Li Zheng thought that the restaurant was about to get off work, so he just raised his hand, "5 minutes." ”

"It's me...... one of them "plopped" and sat next to him, "I forgot that?"

Li Zheng turned his head, only to find that it was the eldest brother with the long inch head who had lined up to enter the office before.

"Teacher Liu Rui, ......" Li Zheng put down what he was doing for the time being, "What's the matter?"

"We have some results on our side, but we can't come up with anything...... I see you're doing that too. Liu Rui said and showed off his computer, "I mainly study the latest three test data, here...... You see...... 176 suspicious frequency curves were synthesized......"

Li Zheng's eyes widened.

He has also looked at these experimental data curves tens of thousands of times.

If ten fat orange cats were placed in front of ordinary people, he would probably find it difficult to tell the difference.

But if there is a person who has raised tens of thousands of orange cats since he was a child, then that person may be able to distinguish each of them, call each cat by name, and describe their kinship.

The current Li Zheng is undoubtedly a super cat breeder.

Although intellectually indescribable, intuitively, he could feel the anomalies of these curves, just as a person can distinguish between the patterns, calls, and even tastes of his own orange and wild orange cats.

"It's kind of interesting......," Li Zheng said with taste, "How did you figure out these curves? What software? What algorithm?"

"Ah, there are no ......" The inch-headed brother rubbed his head, "human eyes, handmade, ...... picked out one by one"

"?!?" Li Zheng was shocked.

Even if it's just the last three tests, the content is terrifying.

Here's a less apt example.

Let's say you have a 1.1 million word file stored as a TXT file, which is about 2MB.

Your task is to find the typos in it.

But you can't read the text, you can only read the binary 0s and 1s.

So, you unfold the TXT file in binary format.

2MB, that's two megabytes.

16777216 bits.

A bit, which represents a binary number, 0, or one.

The final result is a series of 16777216 digits long.

And what the big brother is doing is to read this supernormal series of numbers that I don't know how many screens it takes.

It is through the naked eye, hands and intuition that from these 16777216 0s and 1s, find out what he does not like to see, and it may be a typo.

Everyone knows that the root of the malfunction is hidden in these data, but it has no language and will not shout out, Li Zheng's method is to find a set of conversion codes between binary and Chinese characters, and restore this as much as possible, so as to find typos.

And the big brother with an inch head is burying his head in these 0s and 1s, looking at them one by one with his eyes, and sifting them line by row with his hands.

Savage and rugged.

During this period, the terrifying perseverance and determination made Li Zheng a little embarrassed.

But no matter how amazing the big brother's instincts are, it is impossible to hit them with one hit.

As a result, he broadly picked out 176 suspicious curves.

"How long have you been doing it......" Li Zheng grabbed the computer and looked at it in dismay.

"I've been doing it since that night, and I just finished it for dinner...... Liu Rui asked a little shyly, "Do you think it helps?"

"I'm not sure, but ......" Li Zheng looked at these jumping curves, and his brain seemed to resonate, "I'm inspired...... I'm inspired!"

"Then I should have shown you earlier. Liu Rui shook his head and sighed, "Actually, I will post one to share with everyone when I find one, but every time I seem to find the wrong one, it always fails after research, it is quite a delay in time, and no one will take it seriously later." And I'm not sure it's feasible myself, and even if it does, I may have missed the fatal one and chosen a lot of irrelevant ones......"

"Okay, don't talk......" Li Zheng pushed the computer back, and the storm in his skull swept over, "Send it to me, now...... These curves are not pleasing to my eye, there must be some kind of commonality...... The point is not in any one of them, but in their commonality! Any one, any ten of them are meaningless, but you pick them out and put them together...... Fuck it!"

Li Zheng ...... Are you alright......"

"Very good!" Li Zheng grabbed Liu Rui's shoulder and roared, "You're mine tonight!

This moment.

It's hard to say anything else.

The restaurant aunt is really scared.
