After saying this, Lin Yujing was more confident than studying rockets, and her face was full of determination: "I guarantee that every second will be accurate."

Li Zheng shook his head, stood up and muttered: "My thinking is not inspired by inspiration, so I still study data and algorithms."

"It's up to you. Just get off work at six o'clock."

"Is seven o'clock okay? Have a meal before leaving."

"no."

"Why are you so strict?"

"It's just that strict."

"Why don't you just work overtime..."

Li Zheng returned to his work station angrily.

What greeted him was Lin Yujing's face filled with comfort.

It seemed like it was written on her face - Finally someone can cure you!

…

Since working with Du Songtao, the pace of work has obviously changed.

There is no pressure and no deadlines. Once in a while, if anyone has inspiration, we can chat together. Otherwise, we just work on our own things.

After two weeks of this...

Sure enough, there was no progress!

During this period, Li Zheng also took three days off and went to Hengshui to win a gold medal in biology. He ranked seventh in the country and created his worst record since participating in the competition. Even the questions asked about him were full of regrets.

Affection.

However, during this process, Li Zheng's determination was not dispelled by Du Songtao's work style. He still insisted on using his limited expertise, hoping to use mathematics to find something in the test data.

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

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

Unlike the tepid "Airborne Division", the opinions of the YF-87 team have been divided into two fierce factions.

First, replace materials and strengthen the entire shaft system.

Although it is impossible to accurately diagnose the cause, since the fault phenomenon is a fracture of the shaft system, strengthening this weak link is naturally a feasible way.

The cost of this is a significant increase in engine weight and a 5% to 15% reduction in rocket payload. Although I am not sure that it will 100% solve the problem, this solution is intuitive and fast. It can use the factory's production capacity before the start of 927 construction and complete it before the end of the year.

Test drive.

Second, redesign the entire engine.

As Du Songtao said, the launch vehicle is a complex and precise project.

Many times, finding the fault and correcting it is far more expensive than starting a new redesign.

If it cannot be completely improved in a short period of time, then push it back to the beginning.

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

It's like randomly throwing a number from 1 to 100. 1 to 98 all represent successful launches, and 99 and 100 represent failures.

The first time, I was unlucky and got 99.

Then if we do it again, we will never be unlucky in a row.

The advantage of this plan is that it is more likely to eradicate the disease and opens up room for Huang Er's longer-term development.

The disadvantages are also obvious. Redesigning the engine will not be completed within one year. Adopting this plan is equivalent to publicly announcing that Huang Er will give way to the 927.

China's large-scale hydrogen-oxygen engine is really a long-term plan.

These two plans were naturally mentioned on Zhao Zhenhua's desk.

At this time, Zhao Zhenhua had newly dyed his hair, and all the gray hair was gone.

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

"Ming Yue... I haven't experienced anything in the Seventeenth Institute... Can't you get over this hurdle?" Zhao Zhenhua clutched the report, his eyes a little distracted, "Reducing such a large effective carrying load, then what is the meaning of Huang Er?

Does it exist? Isn't the purpose of using hydrogen and oxygen just to pursue a more extreme load? This is equivalent to a person actively reducing his weight in order to run faster, but you find that his bones have become brittle, so you put it on him

There are two layers of steel plates on the legs, what’s the point?”

"Prove that he can still run." Zhu Mingyue nodded solemnly, "First run, don't fall down, and then seize the time to study the problem."

"Then we have become the sinners who delayed the development of aerospace?" Zhao Zhenhua weakly raised the report, stared at Zhu Mingyue and said, "Use such a deceptive plan to obtain more resources, tinker with it, and in a short time

It is indeed possible to protect yourself, but I can't say this thing is stronger than 927."

"Then there's only one other option." Zhu Mingyue sighed, "Give up on what's going on and redesign."

"Alas..." Zhao Zhenhua put down the report, leaned back in his chair, and stared up at the sky for a long time, "How is Du Songtao and his team doing their research?"

"Several ideas have been put forward, but there is a lack of effective evidence and it is difficult to conduct research. Even if there is effective evidence, it may be difficult to find a solution in a short 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 is still focusing on data and algorithms, but his capabilities may have been tapped to the limit." Zhu Mingyue shook his head and said, "He proposed to share data and cooperate with the laboratory of Harbin Institute of Technology, but the matter is so important that I will not do it for the time being.

Not approved.”

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

"Secretary... I... I want to say something a little offensive..." Zhu Mingyue said tangledly, "I hope you will wake up... Now that we are in this situation, we will risk leaking secrets... to do this... to do this

Making things look ridiculous to the outside world is not a wise move."

"Okay, I understand." Zhao Zhenhua raised his arm and said, "Let him apply. Instead of going through the troubleshooting channel of your Sixth Institute, go through the scientific research cooperation channel. Bring it over and I will approve it."

"Secretary..." Zhu Mingyue was on the verge of tears, "Some people are already saying... that you have mental problems... and actually sent two..."

"Let them talk!" Zhao Zhenhua said angrily, "If we could afford to hire top data analysts, what the hell would I expect from two middle school students?! Such projects are not allowed to cooperate with data analysis companies, what do you want me to do?

?! If there is someone who can take on the task, I would like to cooperate with Harbin Institute of Technology. Times are changing, Ming Yue, we must embrace these new technologies. If we can’t hire top talents, then people like Li Zheng are the biggest

Bodhisattva. He does his own thing, and it doesn’t take up your resources. If you cooperate with Harbin Institute of Technology, you’re afraid of losing your eggs!”

"………………"

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

"927 has entered the design stage..."

"Lao Liang's eyes are so damn vicious. With Shen Tinglan here, this process won't take long..."

"I'm sorry, Ming Yue, it is indeed possible to temporarily overcome the current difficulties by using steel plates, but this is a cover-up for my own benefit. If I use this plan to fool the leaders, I will be really crazy."

"I admit that sending Li Zheng there is a bit of a gamble."

"But there are really not many bets I can place."

"If they scold me, just scold me. Anyway, I owe a lot of scoldings from people in my life. I will be scolded for several years in the future. It will not be a loss."

"I understand." Zhu Mingyue nodded, "I will help Li Zheng draft a report when I get back."

"Thank you for your hard work. I am responsible for this. If you go through the scientific research cooperation channel, your Sixth Institute does not have to be responsible." Zhao Zhenhua continued, "At this stage, we cannot go the road of making steel plates. It is too late to start over. We can only seize the time and continue.

Searching for the root cause of the disease, of course, is not indefinite. At the latest, the factories will be mobilized for 927. If the root cause of the disease cannot be found by then, you can start over..."

"It's...'us', let's start over again together." Zhu Mingyue swallowed and spit.

"Haha." Zhao Zhenhua smiled, "Don't worry, I will definitely be gone by then."

…

That night, Li Zheng secretly broke the rules.

He didn't get off work at 6 o'clock.

Instead, I huddled in the corner of the restaurant and worked secretly. I worked until 9 o'clock and was still very excited.

The cooperation with Harbin Institute of Technology has been approved, and it must be exciting to cooperate with the strongest domestic laboratory in the field of engineering computing.

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

During this period, Du Songtao and Lin Yujing were certainly not idle, but they were looking for inspiration from the field of mechanical engineering, which was not their expertise. Even if they put forward some ideas, they would not be sustainable.

Of course, they don't have as strong a sense of purpose as Li Zheng, and coming here is just a risky investment.

While he was typing and writing, a voice came.

"Hi……"

"Let's go now..." Li Zheng thought the restaurant was about to get off work, so he just raised his hand and said, "Five minutes."

"It's me..." A person plopped down next to him, "Have you forgotten?"

Li Zheng turned around and realized that it was the long-haired brother who had lined up to enter the office.

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

"We have some results here, but we can't research anything... I see you are also doing something in this area." Liu Rui said, showing off his computer, "I mainly studied the latest three test drive data, here...
