Chapter 753 I'm Afraid the Problem Is Not Small

Redo the core module, even if the Hangke Group can afford the money, Lu Zhou, who is the chief designer of the Lunar Orbit Construction Committee, can't afford to wait.

The fuel and working medium of the Xiangrui are all replenished, and it is almost ready to launch. How dare you tell me that there is something wrong with the core module?

This damn?

Of course not!

Walking back and forth in the corridor for two steps, Lu Zhou made up his mind and said to the phone.

"I'm going to Jinmen now!"

Director Li on the other end of the phone froze for a moment.

"What are you going to do... Do you still understand the space station?"

There are so many experts in the Air Science Group who can't solve it there, including Academician Yuan who shook his head when he saw it. What's the use of you as a layman?

The main research and development projects of Xingkong Technology are all on the electric propulsion system, but not including the space station system design, maybe the entire Jinling Institute for Advanced Study, and even an engineer in this direction cannot be found.

Lu Zhou gritted his teeth and said, "The solution is all thought up by people, let me see if it can be solved!"

If this really makes the Air Science Group remove the shell of the core cabin, which is basically dead from drought, and rewire the loop heat pipe inside, it may not be able to go to the sky smoothly until the end of this year.

Even if he couldn't solve the specific technical problem, he planned to go to the scene to see what was going on.

Taking 10,000 steps back really can't solve it, so I can completely give up on myself.

Seeing Lu Zhou's resolute attitude, Director Li stopped persuading him and said after a pause.

"That's okay... I'll say hello to the Air Science Group and tell them not to rush to dismantle the core module."

"Well, please."

After saying goodbye to Director Li, Lu Zhou hung up the phone, put the phone back in his pocket, and walked quickly back to the laboratory.

Yang Xu, who was removing the slide from the microscope and cleaning up the laboratory table, noticed the solemn expression on Lu Zhou's face, hesitated a little, and asked.

"……What's wrong?"

Lu Zhou said solemnly: "There is something wrong with the Hangke Group, and the launch plan may have to be postponed."

Yang Xu pushed his glasses and asked, "Is the problem serious?"

Although his research scope has nothing to do with aerospace, but as one of the top executives of Jinling Institute for Advanced Study, he still pays attention to such important matters habitually.

"I'm afraid it's a little serious. I may be on a business trip for a week or two. I'll leave the research on N-1 materials to you..." Lu Zhou was about to go out, but he landed on the sample of carbon nanotube fibers on the experimental table. on the glass dish.

I saw him staring at it for a while, and suddenly said without warning, "...What is the maximum length we can do so far?"

Yang Xu hesitated and replied: "About 1-2mm...what's the matter?"

Without hesitation, Lu Zhou immediately said: "Tomorrow you will go on a business trip with me!"

Yang Xu: "...?"

...

In the Aerospace City of Jinmen, the atmosphere was gloomy and gloomy.

Originally, because of the overtime work, the mood of the big guys was not very high, but now that something like this suddenly happened, many people's moods became even more depressed.

Especially the engineers of the Space System Project Department of the Fifth Academy, the expressions on their faces were not very good.

Sun Yuanpei, the engineer in charge of the Moon Palace, was sitting on a small bench at the entrance of the workshop, smoking cigarettes one after another. The deep ravine on his forehead seemed to have aged ten years overnight. The director came over and he didn't even notice.

"...The inside is the core cabin of our group, I'll take you in and have a look."

"Okay." Nodding to Director Zhang, Lu Zhou sized up the old-looking engineer sitting at the door, and cast a questioning gaze, "...is this?"

"...This is the engineer of our space station project and the person in charge of the cooling system."

Hearing Director Zhang's words, Lu Zhou's eyes suddenly appeared.

I see.

No wonder he's in a bad mood right now.

With such a big problem, I am afraid that no one will be happy.

Attracted by the conversation next to him, Sun Yunpei looked up at Lu Zhou, then lowered his head, silently smoking the cigarette in his mouth.

Lu Zhou: "You are Sun Gong?"

Sun Yuanpei nodded.

"Yes."

"Has a remedy been found?"

With a bitter expression on his face, Sun Yuanpei shook his head dejectedly, and silently smoked a cigarette and said, "The current solution is to redesign the loop heat pipe... Dismantling and rebuilding is the best way."

To be honest, as a conservative, he doesn't like Lu Zhou very much.

But at this moment, no matter what he thinks in his heart, he has no position to hate this person.

In contrast, he hated himself more for not discovering the problem before finishing the production.

Lu Zhou stared at him for a while, then said.

"Pip out the cigarette first, and then take me in to have a look."

"Yes."

Responding without much vitality, Sun Yuanpei pinched off the cigarette butt in his hand, threw it into the trash can next to him, then stood up silently, like a puppet without a soul, and walked woodenly into the factory building .

Director Zhang looked at Lu Zhou, sighed and said.

"Don't irritate him either...he was hit a bit hard."

Lu Zhou gave him a reassuring look, smiled and said, "Why should I provoke him?"

Yang Xu, who had been silent behind Lu Zhou, glanced at the direction of the factory gate and asked, "Do I need to avoid it? After all... there are state secrets in it, right?"

After returning to China, he had been with Lu Zhou for so long, and the words he heard most from Lu Zhou were state secrets.

It made him almost have a shadow now.

Director Zhang smiled and shook his head.

"It's okay, the contents inside are not state secrets. Two months ago, Jinmen Sixth Primary School organized a group of sixth-grade children to come and visit... Come with me."

After speaking, he took the lead and walked into the factory building.

Following Director Zhang, Lu Zhou and Yang Xu also walked into the workshop.

Ever since he walked in here, Yang Xu has been looking left and right curiously.

He studies materials science and has never been involved in aerospace. The things here are quite new to him.

He was no longer surprised by these things, so Lu Zhou didn't do anything unnecessary, and went straight to the core module that was placed in the center of the field and was ready to be disassembled.

The location of the connection port has been opened, which can accommodate a fully armed astronaut to drill inside.

However, Lu Zhou didn't do that. He just stood outside, put his head in and took a look, and then backed out.

"The problem is the loop heat pipe?"

Sun Yuanpei nodded weakly: "Yes."

Lu Zhou immediately asked: "What about the coolant? Have you considered changing the coolant?"

A self-deprecating smile curled up on the corner of Sun Yuanpei's mouth, he shook his head and said.

"The coolant is ethylene glycol/water, which is already a good aerospace coolant...you expect to change the coolant to solve this problem? It's useless, give up. Increase the speed of the coolant, improve the ethylene glycol Mixing ratio with water... We have tried all the methods that can be used. The problem lies in the material of the loop heat pipe itself, and the excess heat is accumulated in the capillary structure and the heat input port, which cannot be taken away at all.”

Sure enough, the problem is not that simple.

With a solemn expression on Lu Zhou's face, he walked around the core cabin twice, carefully recalling the wreckage No. 3 lying in his underground laboratory in his mind, and desperately thinking about the solution to the problem.

At this moment, his heart suddenly moved slightly, and he got in through the left port of the core cabin again.

Looking at the exposed half heat pipe and capillary structure extending from the bulkhead, Lu Zhou stretched out his gloved hand to tap on it, and asked, "What material is this made of?"

Sun Yuanpei glanced into the core cabin, and replied: "Copper-aluminum alloy, the loop heat pipes of spacecraft are basically used for this... Is there any problem?"

"Nothing, just asking."

Climbing out of the core cabin, he stood up straight and took two steps back. Lu Zhou exchanged glances with Yang Xu, who was stunned the whole time, and asked.

"Is it possible to electroplate N-1 material?"

As soon as he heard Lu Zhou ask about his major, Yang Xu's eyes that were originally a bit confused suddenly sharpened a little, and he pushed his glasses and said.

"It can be done... What are you going to plate?"

"Copper plating."

"Bronze?" Yang Xu glanced at Lu Zhou in surprise, and then at the core cabin, with a strange look on his face, "Are you planning to..."

Lu Zhou nodded.

"Yes, that's right."

Yang Xu thought for a moment before speaking.

"Electroplating copper on μm-level powder may not work...Electroless plating should be fine."

"Then electroless plating, you are more familiar with how to operate it than I am."

Standing behind the two people, listening to their conversation, Director Zhang stared blankly at Lu Zhou, then at the strange man with glasses, and couldn't help asking.

"what are you guys saying."

Lu Zhou smiled, but he didn't make it clear, he just threw a sentence lightly.

"I'm talking about the remedy!"

After all, Director Zhang with a shocked face was left behind, and he led Yang Xu out of the factory building.
