Chapter 317 (2/2)
One is to replace materials and strengthen the whole shafting.
Although the cause of the disease can not be diagnosed accurately, since the fault phenomenon is shaft fracture, it is naturally a feasible way to strengthen this weak link.
The cost is a substantial increase in engine weight and a reduction of rocket payload by 5% to 15%. Although we are not sure that 100% of the problem will be solved, this solution is more intuitive and quick. We can use the capacity of the factory before 927 starts construction and complete the test run before the end of the year.
Second, redesign the whole engine.
As Du Songtao said, launch vehicle is a complex and sophisticated engineering.
Most of the time, finding faults and correcting them is far more expensive than redesigning them from scratch.
If it can't be improved completely in a short time, it will be pushed back to the beginning.
This kind of inexplicable low probability fault can not occur twice in succession.
Just like throwing a number randomly from 1 to 100, 1-98 represents successful launch, 99 and 100 represent failure.
The first time, unfortunately, I hit 99.
Do it again. It's impossible to have a bad day.
The advantage of this scheme is that it is more likely to eradicate the disease, and it opens up more long-term development space for Huang er.
The disadvantages are also obvious. The redesign of the engine will not be completed in one year. Adopting this plan is equivalent to publicly announcing Huang er's abdication to 927.
China's large-scale hydrogen and oxygen engine is really a long-term consideration.
These two sets of plans also naturally mentioned on Zhao Zhenhua's desk.
At this time, Zhao Zhenhua had newly dyed his hair, and all his white hair was gone.
But in contrast to this black hair, his face is more old.
”Mingyue Seventeen have never experienced Can't we get through this Zhao Zhenhua clings to the report, his eyes are a little lost, ”reducing such a large effective carrying load, does the significance of Huang Er still exist? Is not the purpose of hydrogen and oxygen to pursue more extreme load? This is equivalent to a person to run faster, take the initiative to reduce their weight, but you found that his bones have become brittle, so you put two steel plates on his legs. What's the point? ”
”Prove he can run.” Zhu Mingyue nodded heavily, ”run first, don't fall down, and then seize the time to study the problem.”
”Then, are we not the culprits who delay the development of space?” Zhao Zhenhua held up the report powerlessly, staring at Zhu Mingyue and said, ”with such a scheme to fool people, strive for more resources and mend up, it is possible to protect oneself in a short time, but I can't say that this is stronger than 927.”
”There's only one other plan.” Zhu Mingyue sighed, ”give up the present, redesign.”
”Alas...” Zhao Zhenhua put down the report, leaned on the back of his chair, looked up at the sky for a long time, ”how are Du Songtao and their research going?”
”Several ideas have been put forward, but it is difficult to carry out research due to the lack of effective evidence. Even if there is effective evidence, it is difficult to find a solution in a short time.”
”No, it's not Li Zheng's style...” Zhao Zhenhua again straightened up, ”has Li Zheng made any progress?”
”As far as I know, he is still focusing on data and algorithms, but his ability may have reached the limit.” Zhu Mingyue shook his head and said, ”he proposed to share data and cooperate with the laboratories of Harbin Institute of technology, but it is of great importance. I have not approved it yet.”
”Why?” Zhao Zhenhua glared, ”I didn't mean to cooperate as much as possible?”
”Secretary I I say something offensive... ” Zhu Mingyue tangled and said, ”I hope you are sober Now this is the situation, we are facing the risk of leakage Do this It's not wise to do things that make the outside world seem ridiculous. ””OK, I know.” Zhao Zhenhua raised his arm and said, ”let him apply, not go through the fault treatment channel of your six institutes, take it through the scientific research cooperation channel, and take it, and I will approve it.”
”Secretary...” Zhu Mingyue wants to cry without tears. ”Someone has said Say you have a problem with your spirit I sent two
”Let them say it!” Zhao Zhenhua, who is angry with the case, said, ”if we can afford top data analysts, my mother will expect two middle school students?! This kind of project does not let cooperate with data analysis company, what do you want me to do?! Someone can carry things up and find cooperation with Harbin University of technology. I have already burned incense. The times are changing. Mingyue, we must embrace these new technologies. If we don't invite the top talents, then people like Li Zheng are the biggest Bodhisattva. He did him, and did not take up your resources. You are afraid of an egg when he cooperates with Harbin University of technology! ”
“………………”
After a long silence, Zhao Zhenhua just managed to take care of his hair and calm himself down.
”927 has entered the design stage...”
”Lao Liang's eyes are really fucking poisonous. Shen hearsan is in it. This process will not be too long...”
”No, Mingyue, it is possible to get through the difficulties in front of me temporarily by beating steel plate, but this belongs to hiding the sea for my own benefit. If I take this scheme to fool the leaders from hiding from the sea, I am really crazy.”
”I admit that sending Li Zheng is a gambler.”
”But I can make a note. It's not much.”
”They scold me and scold me. Anyway, I owe a lot of people's scolding in my life. I have been scolded for a few years later, not losing it.”
”I know.” Zhu Mingyue nodded, ”go back and help Li Zheng draft the report.”
”It's hard work. I think I have to go through the channel of scientific research cooperation. You six institutes do not have to be responsible.” Zhao went on to say, ”at this stage, the road to steel plate cannot be taken, and the plan to focus on it is not enough. We can only take time to continue to find the root of the disease. Of course, this is not indefinite. In the latest December, 927 will be moved for 927. If you can not find the root, you will come back... ””
”Yes ”We” let's go back together. ” Zhu Mingyue swallowed his mouth and froze.
”Ha ha.” Zhao Zhenhua smiled, ”rest assured, I must have been absent at that time.”
……
That night, Li Zheng secretly violated the rules.
He didn't get off work at 6.
But in the corner of the restaurant, secretly work, until 9 o'clock, still very excited.
Cooperation with Harbin Engineering University has been approved and cooperation with the strongest laboratory in the field of engineering calculation must be heartening.
Therefore, he should strive to make a meeting ceremony, fully express his limited achievements in this period of time, reduce the understanding cost of Harbin University and study it in depth as soon as possible.
During this period, Du Songtao and Lin yuejing were not idle, but they were looking for inspiration from the field of mechanical engineering. This is not their specialty. Even if some ideas are put forward, they can not be continued.
Of course, they didn't have such a strong sense of purpose as Li Zheng. It was just a venture capital to come here.
Between the hard key fast books, a sound came.
”Hi...”
”This is the way...” Li Zheng thought it was the restaurant to leave work, only one raised his hand, ”5 minutes.”
”It's me...” A man ”plops” and sits next to him. ”Forget that?”
Li Zheng turned his head and found that it was the long inch elder brother who had been queuing in the office before.
”Mr. Liu Rui...” Li Zheng put down his business for a while. ”What is it?”
”We have some achievements here, but we can't find out anything I think you're doing this too. ” Liu Rui said that he showed his computer, ”I mainly study the latest three test data, here You see 176 suspicious frequency curves are integrated... ”
Li Zheng stared at him.
He has also looked at these experimental data curves tens of thousands of times.
If ten fat orange cats are put in front of ordinary people, it is difficult for him to distinguish the difference.
But if a man raised tens of thousands of orange cats from childhood to college, he might be able to distinguish each of them as many as a few treasures, name each cat and describe their relationship.
Li Zheng is undoubtedly a big cat raising household.
Although it is not reasonably descriptive, intuitively, he can feel the abnormal curves, just as a person can separate the patterns, sounds, and even taste of his own orange cat and wild orange cat.
”It's a little interesting...” Li Zheng said savoring, ”how did you pull out these curves? What software? What algorithm? ”
”Ah, there's no one...” The big brother knead his head. ”People's eyes, handmade, picked out one by one...”
“？！？” Li Zheng was surprised.
Even if it's just the last three tests, the content is scary.
Take a less appropriate example.Suppose you have a novel of 1.1 million words, stored as a TXT file, about 2MB.
Your job is to find the typos.
But you can't read text, you can only read binary 0 and 1.
So, you expand the txt file in binary form.
2MB, or two megabytes.
16777216 bits.
A bit represents a binary number, 0, or one.
The final result is a sequence of 16777216 bits.
And what cuntou big brother is doing is reading this extraordinary sequence of numbers that we don't know how many screens it takes to fit.
It is through the naked eye, hands and intuition to find out what he does not like from the 16777216 zeros and ones, which may be the wrong spelling.
Everyone knows that the root of the fault lies 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 recover the novel as much as possible, so as to find the wrong characters.
But the cuntou big brother, is buries the head these 0 and 1, with the eye one by one, uses both hands row by row sieve.
Savage and rough.
In the meantime, Li Zheng was embarrassed by his terrifying perseverance and determination.
But even if the big brother's intuition is amazing, it is impossible to hit the target with one blow.
So he broadly picked 176 suspicious curves.
”How long have you been doing it...” Li Zheng grabs the computer and looks at it in amazement.
”I've been doing it since that night. I've just finished eating...” Liu Rui asked shyly, ”do you think it helps?”
”I'm not sure, but...” Li Zheng looked at these leaping curves, and naoren seemed to resonate with him, ”inspiration I've got a goddamn inspiration
”Then I should have shown it to you earlier.” Liu Rui shook his head and sighed, ”in fact, if I find one, I will publish one to share with you. But every time I find it wrong, it always ends up in the end. It's a waste of time, and no one will take it seriously. And I don't know that this way is feasible. Even if it is, I may have missed the fatal one and chose many unimportant ones... ”
”All right, don't talk...” Li Zheng pushed the computer back, and a storm swept through his brain. ”Send it to me, now I don't like these curves. There must be something in common The key is not any one of them, but their commonness! Any one, any ten is meaningless, but you choose them and put them together Send the damn thing
”Li Zheng Are you ok... ”
”Very good!” Li Zheng grabbed Liu Rui's shoulder and growled, ”you are mine tonight! Don't want to go anywhere! ”
This moment.
It's hard to say anything else.
The restaurant aunt is really scared.
