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

The fuel and working fluid of the Xiangrui have been replenished, and it is almost launched, and you actually told me that there was a problem with the core module?

This Nima forbearance?

Of course not!

After pacing back and forth in the corridor for two steps, Lu Zhou made up his mind and said into his phone.

"I'm going to Jinmen!"

Director Li on the other end of the phone was stunned.

"What are you going to do...... Do you still know that the space station can't be? ”

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

The main R&D projects of Star Technology are all on the electric propulsion system, but it does not include the design of the space station system.

Lu Zhou gritted his teeth and said: "The solutions are all thought up by people, whether it can be solved or not let me see it first!" ”

If this really allows the Hangke Group to remove the shell of the core cabin that is basically dry and die, and re-wiring the loop heat pipes inside, I am afraid that it may not be able to go smoothly until the end of this year.

Even if he can't solve the specific technical problem, he plans to go to the scene to see what the situation is.

It really can't be solved by taking 10,000 steps back, so that you can completely die.

Seeing Lu Zhou's resolute attitude, Director Li no longer persuaded anything, and paused for a while to speak.

"Okay...... I said hello to the Hangke Group and asked them not to rush to dismantle the core cabin. ”

"Well, please."

After saying goodbye to Director Li, Lu Zhou hung up the phone, stuffed the phone back into his pocket, and walked briskly back to the laboratory.

Yang Xu, who was taking the slide off the microscope and cleaning up the experimental table, noticed the solemn expression on Lu Zhou's face, hesitated slightly, and asked.

“…… What's wrong? ”

Lu Zhou said with a solemn expression: "There is something wrong with the Hangke Group, and I am afraid that the launch plan will have to be postponed." ”

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

Although his research scope is not close to that of the aerospace eight poles, as one of the senior leaders of the Jinling Institute for Advanced Study, he is still habitually concerned about such a major matter.

"I'm afraid it's a bit serious, I may have to wait a week or two, and the research of N-1 materials will be entrusted to you......" Lu Zhou was about to go out, but the realization landed on the glass dish containing carbon nanotube fiber samples on the experimental table.

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

Yang Xu hesitated and replied, "About 1-2mm...... What's wrong? ”

Without hesitation, Lu Zhou immediately said, "You go on a business trip with me tomorrow!" ”

Yang Xu: "......? ”

……

In the space city of Jinmen, the atmosphere was gloomy and bleak.

Originally, because of overtime, the mood of the big guys was not very high, but now that there is a sudden incident, many people's mood is even lower.

Especially the engineers of the Space System Project Department of the Fifth Academy of Sciences did not have very good expressions on their faces.

Sun Yuanpei, the engineer in charge of the Moon Palace, sat on the small bench at the door of the factory, smoking cigarettes one after another, and the deep ravine in front of his forehead seemed to have aged more than ten years overnight, and he didn't even notice that Director Zhang, who was in charge of the space station project, came over.

“…… Inside is the core cabin of our group, so I'll take you inside to have a look. ”

"Okay," nodded to Director Zhang, Lu Zhou glanced at the engineer who looked a little old at the door, and cast an inquiring gaze, "...... Who 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, a sudden surprise appeared in Lu Zhou's eyes.

I see.

No wonder he's not in a good mood at this moment.

There is such a big problem, but I am afraid that no one can be happy.

Attracted by the sound of conversation next to him, Sun Yunpei looked up at Lu Zhou, lowered his head again, and silently smoked the cigarette in his mouth.

Lu Zhou: "You are Sun Gong?" ”

Sun Yuanpei nodded.

"Yes."

"Have you found a remedy?"

The expression on his face was a little bitter, Sun Yuanpei shook his head dejectedly, and said silently: "The only way now is to redesign the loop heat pipe...... Dismantling and rebuilding is the best way to do it. ”

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

But at this moment, no matter what he thought in his heart, he didn't have a position to hate this person.

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

Lu Zhou stared at him for a while and spoke.

"You snuff out your cigarette first, and then take me inside to have a look."

"Yes."

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

Director Zhang looked at Lu Zhou and said with a sigh.

"Don't irritate him...... He was hit a little harder. ”

Lu Zhou gave him a reassuring look, smiled and said, "What did I stimulate him to do." ”

Yang Xu, who had been following Lu Zhou without speaking, glanced at the direction of the factory gate and asked, "Do I need to avoid it?" After all...... There's a state secret in it, right? ”

After returning to China, he followed Lu Zhou for so long, and the word he heard the most from Lu Zhou's mouth was state secrets.

He's almost in a shadow now.

Director Zhang smiled and shook his head.

"It's okay, the things inside are not state secrets, and two months ago, a group of sixth-grade children from Jinmen Sixth Elementary School were organized to visit...... Come with me. ”

After saying that, he took the lead and walked towards the factory.

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

From the moment he walked in here, Yang Xu had been curiously looking left and right.

He studied materials science, and he had never been exposed to aerospace, so the things here were quite new to him.

Already strange about these things, Lu Zhou didn't do anything superfluous, and walked straight to the core cabin that was placed in the center of the field and was ready to be dismantled.

The opening has been opened to accommodate a heavily armed astronaut to drill inside.

However, Lu Zhou didn't do this, just stood outside, stuck his head in and glanced twice, and then retreated.

"What's the problem with the loop heat pipes?"

Sun Yuanpei nodded weakly: "Yes." ”

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

The corners of Sun Yuanpei's mouth pulled up a self-deprecating smile, shook his head and said.

"The coolant is glycol/water, which itself is already a good aerospace coolant...... Are you counting on a coolant change to solve this problem? It's useless, give up. Increase the running speed of the coolant and improve the mixing ratio of ethylene glycol and water...... We've tried everything we can do. The problem is that the material of the loop heat pipe itself is that the excess heat accumulates in the capillary structure and the heat input port, and cannot be carried away at all. ”

Sure enough, the problem is not that simple.

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

At this moment, his heart suddenly moved slightly, and he drilled into the left port of the core module again.

Looking at the half-cut heat pipes and capillaries that extended from the bulkhead and were exposed, Lu Zhou stretched out his gloved hand and knocked on it, while asking, "What kind of material is this made of?" ”

Sun Yuanpei glanced into the core module and replied: "Copper and aluminum alloy, the loop heat pipe of the spacecraft is basically used for this...... Any questions? ”

"Nothing, just asking."

Crawled out of the core cabin, stood up straight and took two steps back, Lu Zhou exchanged glances with Yang Xu, who looked confused throughout the whole process, and asked.

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

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

"If you can do it, you can do it...... What are you going to plate? ”

"Copper."

"Copper?" Yang Xu glanced at Lu Zhou in a little surprise, and then at the core cabin, his expression suddenly became a little weird, "Are you planning to ......?"

Lu Zhou nodded.

"Yes, that's right."

Yang Xu thought for a moment before speaking.

"Copper plating on μm-level powder may not work...... Electroless plating should be fine. ”

"Then electroless plating, you are more familiar with how to operate than me."

Standing behind the two people, listening to their conversation, Director Zhang looked at Lu Zhou in a daze, and then glanced at the strange man with glasses, and couldn't help but ask out loud.

"What are you talking about?"

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

"I'm talking about a remedy!"

After that, Director Zhang, who was left with a shocked face, took Yang Xu and walked outside the factory.
