Chapter 752: I'm afraid the problem is not small

Redoing the core module again, even if Luke Group can afford the money, Lu Zhou, the chief designer of the Lunar Orbit Construction Committee, can't wait.
After the Xiangrui's fuel and working fluid were replenished, it was almost launched. Did you tell me that something was wrong with the core module?
This Nima Ren?
Of course not!
Taking two steps back and forth in the corridor, Lu Zhou made up his mind and said to his mobile phone.
"I'll go to Jinmen now!"
Director Li froze over the phone.
"What are you doing ... do you know that the space station will not work?"
There are so many experts in the Hangke Group that they can't solve them, including Academician Yuan, who shook his head. What can you do if you are a layman?
The main research and development projects of Xingkong Technology are all on the electric propulsion system, but it does not include the design of the space station system. It may mean that the entire Jinling Advanced Research Institute cannot be found by even engineers in this direction.
Lu Zhou gritted his teeth and said, "The methods are all people come up with. Can you solve it before I see it?"
If this really causes the Hangke Group to remove the basic dry-shell of the core cabin and re-wire the loop heat pipe inside, I am afraid that it may not be able to go to the sky smoothly by 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 is going on.
Stepping back 10,000 steps really can't be solved, but also let myself be completely disheartened.
Seeing Lu Zhou's resolute attitude, Director Li no longer persuaded anything and paused for a while.
"That line ... I said hello to Hang Ke Group, so they don't rush to dismantle the core compartment first."
"Well, please."
Saying goodbye to Director Li, Lu Zhou hung up the phone, shoved the phone back into his pocket, and walked quickly back to the laboratory.
Yang Xu, who was removing the slide from the microscope, and cleaned up the experimental table, noticed the heavy expression on Lu Zhou's face, hesitated slightly, and asked.
"……what happened?"
Lu Zhou said solemnly: "There is something wrong with the Aviation Group, and the launch plan may be delayed."
Yang Xu pushed his glasses and asked, "Is the problem serious?"
Although his research scope and the aerospace eight poles could not be reached, as one of the senior members of the Jinling Institute of Advanced Research, he was habitually concerned about such important matters.
"I'm afraid it's a little bit serious. I may conclude that you have a week or two to study the N-1 materials ..." Lu Zhou is preparing to go out, but the realization is on the experimental table with the carbon nanotube fiber sample Glass dish.
I saw him staring for a while, then suddenly said without warning, "... What is the maximum length we can achieve at the moment?"
Yang Xu hesitated and replied, "About 1-2mm ... what happened?"
Without hesitation, Lu Zhou said immediately, "Tomorrow you will be traveling with me!"
Yang Xu: "...?"
...
In Jinmen ’s Space City, the atmosphere was gloomy and bleak.
Originally, because of overtime, the emotions of big guys were not very high. Now suddenly there is something in this class, and many people's emotions are even lower.
Especially the engineers of the Space System Project Department of the Fifth Academy of Sciences, the expressions on their faces are not very good.
Sun Yuanpei, the engineer in charge of the Moon Palace, sat on a small bench in front of the factory building, smoking cigarettes one by one. The deep gully in his forehead seemed to be a dozen years old overnight, even Zhang, who was in charge of the space station project. The director came over and he didn't notice.
"... Inside is the core cabin of our group, and I'll take you inside to see."
"Okay," nodded to Director Zhang, Lu Zhou glanced at the old engineer sitting at the door, who looked a little old, and cast his gaze at the question. "... This is it?"
"... 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 appearance appeared in Lu Zhou's eyes.
That's it.
No wonder he's not very emotional at the moment.
With such a big problem, I'm afraid everyone can't be happy.
Attracted by the sound of the conversation next to him, Sun Yunpei looked up at Luzhou, lowered his head again, and silently smoked the cigarette that was licking around his mouth.
Lu Zhou: "You are Sun Gong?"
Sun Yuanpei nodded.
"Yes."
"Have you found a remedy?"
The expression on his face was a bit bitter, and Sun Yuanpei shook his head with a stunned expression, and said quietly, "The current method can only redesign the loop heat pipe ... It is best to dismantle and rebuild."
To be honest, he doesn't like Lu Zhou very much among the conservatives.
But now, no matter what he thought, he didn't hate this person's position.
In contrast, he hated himself more, why he didn't find the problem before finishing production.
Lu Zhou stared at him for a moment and said.
"You put out the cigarette first, and then take me in to see."
"Yes."
There was not much vitality, and Sun Yuanpei took off his cigarette and threw it into the trash bin next to him. Then he stood up silently, like a puppet without a soul. .
Director Zhang looked at Lu Zhou and sighed.
"Don't provoke him too ... he was hit a little harder."
Lu Zhou gave him a reassuring look, smiled and said, "I stimulate him for what."
Yang Xu, who had not spoken behind Lu Zhou, looked at the door of the factory building and asked, "Do I need to avoid it? After all ... is there a state secret in it?"
After returning home for so long with the landing boat, the word he heard the most from Lu Zhou's mouth was state secrets.
He's almost in shadow now.
Director Zhang shook his head with a smile.
"It's okay, nothing inside can be said of any state secrets. Two months ago, there was a group of sixth-grade children from the Sixth Elementary School in Jinmen. Come with me ... Come with me."
After speaking, he took the lead and walked towards the factory.
Following Director Zhang, Lu Zhou and Yang Xu also entered the factory building.
From the moment he walked in here, Yang Xu looked around curiously.
He is studying materials science and has not been exposed to the aerospace industry. The things here are quite new to him.
No wonder about these things. Lu Zhoudao didn't do anything extra and went straight to the core compartment that was placed in the center of the site and was ready to be dismantled.
The position of the connection opening has been opened to accommodate a heavily armed astronaut to drill into it.
However, Lu Zhou didn't do this, he just stood outside, put his head in and squinted, then backed out.
"The problem is with the loop heat pipe?"
Sun Yuanpei nodded weakly: "Yes."
Lu Zhou immediately asked: "What about the coolant? Have you considered replacing the coolant?"
Sun Yuanpei took a hint of self-deprecating smile and shook his head and said.
"The coolant is glycol / water, which is already a good aerospace coolant ... Do you expect to change the coolant to solve this problem? Useless, give it up. Increase the speed of the coolant and improve the glycol. Mixing with water ... We have tried the methods that can be used. The problem is that the excess heat is accumulated on the capillary structure and the heat input port of the material of the loop heat pipe itself, and it cannot be taken away at all. "
Sure enough, the problem is not so simple.
Lu Zhou's dignified expression appeared on his face, and he walked around the core cabin twice. In his mind, he carefully recalled the No. 3 wreck lying in his underground laboratory, thinking hard about the solution to the problem.
Just then, his heart suddenly moved slightly, and he got in again through the left port of the core compartment.
Looking at the half-length heat pipe and capillary structure that extended from the bulkhead, Lu Zhou stretched out his gloved hand and knocked on it, and asked, "What material is this made of?"
Sun Yuanpei squinted into the core capsule and replied, "Copper-aluminum alloy, the loop heat pipe of the spacecraft basically uses this ... Is there any problem?"
"Nothing, just ask."
Climbing out of the core cabin, standing straight and taking two steps back, Lu Zhou and Yang Xu, with a grimace all over the face, exchanged his eyes and asked.
"Is it possible to plate N-1 material?"
Upon hearing Lu Zhou's question about his specialty, Yang Xu's original aggressive eyes were sharpened for a moment, and he pushed his glasses and said.
"All you can do is ... what are you going to plate?"
"Copper plating."
"Bronze?" Yang Xu glanced at Lu Zhou with a little surprise, and then looked at the core compartment. His look was suddenly weird. "Are you planning ..."
Lu Zhou nodded his head ~ EbookFREE.me ~ Yes, yes. "
Yang Xusi spoke for a moment and then spoke.
"I'm afraid that electroplating of copper on μm powders is not possible ... electroless plating should be fine."
"Then electroless plating, you know more about how to operate it than I do."
Standing behind the two people, listening to their conversation, Director Zhang looked at Lu Zhou with a stunned look, and then looked at the strange man in glasses, unable to help asking.
"what are you guys saying."
Lu Zhou smiled, but did not make his point clear, but just tossed it lightly.
"Speaking of remedy!"
Having said that, Director Zhang was left with a look of shock, and he took Yang Xu out of the factory building.
