Study Monster Cultivation System-Chapter 291 - 290. Who could have learned this?

Back in the control room, He Zhongrui revitalized his spirits and began to tour the two interns around while providing an overview.

This was Li Zheng’s first time entering the central control room, which, though small, was fully equipped.

The main wall featured six large screens, two of which showed launch site video surveillance; the remaining four displayed a series of parameters and charts that only insiders could understand.

Opposite the screens were three large rows of desks, with desktops and laptops totaling about twenty to thirty units.

There were not many people in the control room, but everyone wore uniform gray testing suits and special fabric shoes.

It truly resembled a miniature launch center.

In fact, its functions were indeed quite similar to those of a launch center.

At the Western Suburb Test Site, the main task was to oversee the ground testing of the entire rocket.

In simple terms, this involved securing the prototype to the launch pad and letting it run in place. By collecting and analyzing the operational parameters, they aimed to identify any issues.

Where Li Zheng and Lin Yujing stood was, in reality, just the main control room, with the testing stand about a kilometer away.

As for the actual tests, because of the high cost of fuel, they were not frequent; these tests usually saw the presence of individuals like Shen Tinglan.

Now, the main task of the testing team was to reorganize all the test data from Yellow 2 since its inception, to sort out and preliminarily analyze the anomalies that were once not considered abnormal, and to provide feedback to the technical team on a daily basis.

Moreover, the task of fully inspecting the engine test data from external institutions, especially from The Sixth Institute, was truly massive.

"Are we also responsible for the data from The Sixth Institute?" Li Zheng asked as he walked alongside He Zhongrui.

"Technically, they should handle it themselves, but Director Chen insisted on taking all the data for us to screen as well," He Zhongrui, rubbing his eye bags, sighed, "You’ve seen the press release about the launch failure, right?"

"Yes, it said that Core Stage One’s engine shut down early," Lin Yujing stepped forward and asked curiously, "Is it really that?"

"Haha, all my friends asked the same thing," He Zhongrui waved his hand and laughed, "It really is that, don’t listen to any conspiracy theories. The press release definitely can’t reveal core technology, but it wouldn’t lie either."

"So, it was indeed a problem with the engine," Lin Yujing pondered, "The engine YF-87 used in Core Stage One was developed by The Sixth Institute; they must be as tense as our institute now."

"What? What 87? What Sixth Institute?" Li Zheng exclaimed, "When did you suddenly become so knowledgeable?"

Lin Yujing quickly turned her head left and right and asked, "Didn’t you read the administrative documents and project files they gave us yesterday?"

"I didn’t finish until 12 o’clock after I got home and took a shower," Li Zheng angrily clenched his fist, "Typical you, always sneakily studying ahead!"

"Just, I read it on the way home…"

"You were driving then, carrying me!"

"Oh, come on, don’t fuss over it too much…"

Listening from the side, He Zhongrui found something amiss.

Other engineers who appeared to be seriously working also perked up their ears.

The atmosphere in the control room instantly became tense and a bit melancholic.

"Excuse me for asking…" He Zhongrui swallowed, gathered his courage, and asked, "Are you two in a relationship?"

"???!"

"No! No!"

This response, like a refreshing breeze, cleared the tension in the entire control room.

The initially tense engineers became cheerful again.

He Zhongrui also breathed a sigh of relief and said with a smile, "Sorry, sorry, just that you two seem… quite close."

Li Zheng shook his head, "It’s just a normal friendship between classmates."

"There’s no friendship," Lin Yujing added, "It’s merely a competitive relationship from exams."

"Haha, haha, speaking of exams…" He Zhongrui adjusted his glasses and laughed, "Everyone here has also passed through exams, we totally understand the healthy competition among classmates."

The engineers in front of the screens confidently nodded, those with glasses also raised theirs a bit.

People who could sit there were usually ranked among the top ten in their schools.

However, they were just empty, lonely souls in the top ten without any intrigue.

Passionate about competing in exams, cute and lovely high school girls—how come I never met them in my days?

Luckily, what goes around comes around.

Director Chen just arranged for this, didn’t he?

It was time to show ignorant high school students the real charm of a top scholar.

But some still had their doubts.

An engineer who had just taken over leaned over and asked, "Which school are they from again?"

"Lake Ying."

"Aye... I thought they would at least be from No. 4 Middle School or Ren Da Fu," the engineer said, laughing while taking out his laptop, "Must be connections that got them here, right?"

"Heard it was some bigwigs from the Minister of Science and Technology that made a call."

With a smile, the engineer looked up and said, "Kids from that kind of school still hanging on to competing in grades, thinking about it is quite adorable."

The source of this c𝐨ntent is freeweɓnovēl.coɱ.

"Yeah..." another engineer reminisced with a smile, "I fought my way out of Sichuan on a tough bar exam, looking at the kids competing in grades next to Jijing Park, I really don’t know how to laugh."

The two shared a smile and said no more.

They believed there would soon be a chance to show off their skills.

In front of the monitoring wall, He Zhongrui briefly explained to Li Zheng the keywords he didn’t understand.

The first was the YF-87 engine.

"Y" stands for the first letter of "liquid" in pinyin.

"F" stands for the first letter of "engine" in pinyin.

87 represents its series number.

Together, it can be understood as the 87th type of liquid engine.

Similar ones include the WP (turbojet) series, HS (piston) series, and so forth.

The YF-87, a symbol of China’s industrial level, was also developed by The Sixth Institute.

The Sixth Institute, formally known as the Aerospace Propulsion Technology Research Institute, specializes in liquid engines. Its products numbered after YF-50 are basically custom-designed for the Yellow River rocket series and can be said to be the institute that cooperates most closely with Core Stage One.

It was also the institute, alongside Core Stage One, most deeply involved in the recent setback.

Theoretically, troubleshooting internal engine issues should have been completed by the Sixth Institute.

However, clearly, Chen Hongbing was not fully prepared to trust the Sixth Institute under these conditions but instead allowed Core Stage One’s test team to progress simultaneously.

This led to the limited test group members taking on an extremely heavy task, needing to research and analyze thousands of unfamiliar test data and trying to find some clues.

"Right now, the task has been about 17% completed, should speed up as it goes," He Zhongrui said as he led the two to a table piled with materials, "These are the essential knowledge for researching engine test data. You two spend half a day trying to understand as much as you can, and if it’s really too hard, I will arrange other work."

At this moment, an engineer who had just finished setting up the water pipes leaned over and said, "This might be too difficult for high school students, why not have them manage documents instead?"

"I don’t want to... Director Chen just called, asking me to assign them tough tasks," He Zhongrui shook his head helplessly and said to the two, "Honestly speaking, this part of the work usually requires someone who’s been doing it for three to four years to handle, including myself, who had to study for about a week before barely understanding engine testing."

While talking, he casually picked up a document, flipped a page, and looking at the complex charts and data, he muttered, "It’s not that I’m making it hard for you, but if you really don’t understand, let me know, and I’ll check with Director Chen again to see if we can start with something simpler."

"Alright," Li Zheng rubbed his hands and stepped forward, ready to go.

"I... I can’t." Lin Yujing swallowed and raised her hand, "I apply to directly do the simpler tasks..."

"You should have said so earlier," He Zhongrui laughed, "Perfect, you organize the data we sifted through last night, compile it into a document, and send it to the technical group. Come on, I’ll show you."

"No, no, no!" the water-fetching engineer who had been watching the excitement hurried over, "Boss, you handle something else. I can teach this kind of task."

"Eh, you won’t be clear."

"I’ve always done this job, I know it better than you... Team leader, it looks like you’ve been busy all night, you should really get some rest."

"A newcomer has just arrived, is this really the time for me to rest?"

While they were uselessly vying for the task.

Li Zheng had already pulled up a chair at the desk, settling down with draft paper, a notebook, and a calculator neatly arranged in front of him.

He hadn’t even had a chance to search for something to learn when the material literally came to him.

He had to master it thoroughly!

...

Once Li Zheng started studying, he was at it for a full forty minutes.

When he had finished learning and found He Zhongrui, the latter had just finished explaining the document matters to Lin Yujing and was about to head to the break room for a nap.

Seeing Li Zheng approaching, He Zhongrui smiled wearily, "Just as I said, couldn’t understand it, right? Well, I’ve briefed Xiao Lin on the document stuff. Why don’t you start by teaming up with her to sort things out, get to know the work."

"No, I got most of it," Li Zheng beckoned eagerly, "Come on, give me something more challenging."

"???" He Zhongrui blinked, peeking at the desk, "You just read two pages and think you’re fine?"

"I read quite a bit, actually," Li Zheng stubbornly explained, "It’s just that I’ve come across a lot of the knowledge before, so I skipped what I could."

"It’s not that..." He Zhongrui scratched his head, "Aerospace engine knowledge, where would you have encountered that?"

Li Zheng had nothing much to say, only raising an eyebrow, "Come on, Rui Ge, let’s just try a big task."

Seeing his frivolous expression, He Zhongrui got somewhat frustrated, "Li Zheng, take on tasks that match your ability. Given your current situation, do you think I can trust you with a task?"

"Ah, this..." Li Zheng was in a tough spot now.

He didn’t blame He Zhongrui; it was reasonable to assume there was something off with him.

But how could he explain that...

At that moment, a cold laugh suddenly sounded.

"Test him." Lin Yujing, sitting in front of the computer and scanning the document, said, "Just test him casually."

"Brilliant." Li Zheng’s eyes widened as he beckoned to He Zhongrui again, "Test me."

"..." He Zhongrui naturally didn’t want to waste the time, especially as he was feeling sleepy. However, considering the complex nature of these two individuals’ identities, he finally nodded, "Li Zheng, work is really tight right now. If you can’t answer the questions, either go back to studying or help Xiao Lin with the document work. At least don’t add to our burden."

"Absolutely." Li Zheng’s expression grew more serious, "Ask me the tough ones, Teacher He, to save time."

"Give him the tough ones." Lin Yujing egged on from the side.

"Haha..." He Zhongrui gave a wry smile, "I really do want to cut you some slack... but since Xiao Lin said so... I won’t hold back."

"Please..."

He Zhongrui then began to think, rubbing his forehead.

Several others in the office were also sneakily glancing over.

He was only high school level and was now browbeating in the domain of masters and PhDs.

It was time to show the dignified aura of a top student, team leader.

Let Lin Yujing get a good look at the level of the test team.

The title "Aerospace Engineer" wasn’t for show.

As for He Zhongrui, although he was prompted to pose a difficult question, being PhD level, he was reluctant to present an extremely advanced question that the opponent surely couldn’t answer—it would seem like picking on the junior.

On the other hand, he also wanted to take the opportunity to gauge Li Zheng’s level.

So, he posed a stable, moderate question.

"The main failure modes of a pump-fed engine."

Li Zheng immediately answered.

"There are 12 items in the summary."

"1, Joint leakage."

"2, Starter anomalies."

"3, Hot gas leakage."

...

"12, Abnormal actuator operation."

He Zhongrui slightly widened his eyes and immediately asked, "The corresponding occurrence locations for each fault mode?"

"Leakage corresponds to joints, welds, cracks, rotating seals..."

...

"Foreign objects correspond to injectors, turbine pumps, airflow holes."

He Zhongrui, with a grim expression, stared at Li Zheng for a long time before asking, "Did you memorize this before?"

Li Zheng could only respond with a smile.

Who the hell would memorize this stuff?

"No need to memorize," Li Zheng explained. "Once you fully understand the engine structure components, suggesting a fault naturally allows you to analyze the possible locations, understanding is enough."

Not only He Zhongrui, but even those sneakily glancing were somewhat embarrassed.

Screw it, you have to memorize it. What’s there to understand?

They still did not know that Li Zheng, after passing two competitive exams and a series of cognitive trainings...

His brain had already started to work in strange ways.

"..." After a moment of conflict, He Zhongrui asked again, "Please list a few main fault characteristic parameters."

"Flow, pressure thrust, temperature, vibration, rotation speed, stress, torque..."

"Enough," He Zhongrui raised his hand and said, "Briefly explain how to choose characteristic values."

"From the existing N characteristic parameters xi, select n characteristic parameters xk to form the optimal feature subset under a certain index function J, among all possible alternative characteristic values..."

He Zhongrui interrupted Li Zheng again, asking again, "What is AWSSA?"

This time, Li Zheng really thought for a while before saying, "Adaptive Weighted Sum and Average Algorithm, one of the algorithms based on engine characteristic signal analysis for fault diagnosis and prediction."

Suddenly, He Zhongrui turned around, grabbed a paper and pen from the desk, and quickly wrote down two lines of equations that over 60% of people definitely could not understand.

"The top line is the mean of the test parameters, the bottom line is the variance, can you calculate the Grubbs’ statistic?"

"Give me a moment..." Li Zheng took the pen and thought, wrote down a formula that probably only people within 70% of hairline could understand, then pulled out a calculator, rubbing his hands together he said, "Teacher, you go rest for a bit, I’ll compute it slowly."

"No need..." He Zhongrui pressed down on Li Zheng’s arm, his entire face showing a life-questioning innocence, "Why on earth do you even understand fuzzy mathematics?!"

"Just..." Li Zheng hesitated and said, "somewhat understand."

"..." He Zhongrui stared at Li Zheng, as if his eyes were about to shoot out the words "why."

After a long while, he finally let go of his hand and said to someone in the back row.

"You teach him the process of analyzing engine test data."

"... Okay..."

He Zhongrui looked at Li Zheng, then at the pile of materials on the table, and finally asked, "Why..."

Suddenly, another laugh came.

"Haha..." Lin Yujing covered her mouth and laughed, "Now you know how tough I had it... Who can learn all this?"
