Chapter 750: Heat buildup?

Aerospace Technology Group.
In the building of Jinmen Aerospace City, a large cylindrical core cabin is stopping in the center of the building.
Immediately before the last inspection before going to heaven, the engineers of the Fifth Academy are conducting routine safety inspections of the equipment on the core compartment that has been completed.
After checking the wiring of the core cabin door, and confirming that the password can be turned on and off normally, Sun Yuanpei with a safety helmet raised his arm and pinched his forehead, grinned, and chatted with another engineer beside him.
"... Professor Lu, Chief Designer of the Lunar Orbital Construction Committee, this time is really covering the sky."
Zhao Xianpu didn't look up, and hummed, "Isn't it?"
In a word, the launch plan was scheduled at the end of the month, and they had rested on Saturday and Sunday, and immediately ran to the unit.
Sun Yuanpei shook his head and said, "Sometimes I really don't understand this guy is imaginary. Isn't it good to be a veteran in the field of controlled fusion? I heard that this guy made a special trip to the post of director of the Nuclear Fusion Energy Program Executive Center The position of the chief engineer of East Asia Power has also been given to others, and he rushed over to engage in aerospace ... Isn't this neuropathy? "
In his opinion, no matter how the aerospace industry develops, the future is certainly not as good as the controllable nuclear fusion of the sky.
If nothing else, just looking at the controllable fusion technology and the engineers of East Asia Electric Power, how much national interest has China won for China will be enough to meet the bright future of this industry.
However, Professor Lu seemed to turn a blind eye to all this. After completing the research on controllable nuclear fusion, it was like throwing away a toy that was already tired and putting it all aside.
In the eyes of most scientific researchers, this is not only difficult to imagine, it is also incomprehensible.
After working so hard for so long, isn't it just to taste the fruits of the final victory?
It was unbelievable to step out when it was time to pick the fruit.
Zhao Xianpu straightened the helmet on his head and closed the line protection cover on the bulkhead.
"The ghost knows what he thinks."
At this time, a slightly younger engineer next to him interjected and said, "Maybe he is different from us?"
Sun Yuanpei poked his lips: "Can there be any difference between both noses and one eye?"
At this time, footsteps came from outside the factory building, and the three of them immediately chatted.
Not long after, Zheng Xiangdong, deputy general manager of the Hangke Group, and academician Yuan Huanming, chief engineer, walked into the factory building with a group of people.
When he walked in front of Sun Yuanpei, Academician Yuan glanced at the core compartment, and then asked him.
"Is the inspection completed?"
"It has been completed, and there are no problems with all the lines." Sun Yuanpei immediately straightened his back and passed the ticked form to the old gentleman.
After taking the form and glancing at it, Academician Yuan nodded, and then looked at the director of the Space Station System of the Fifth Hospital behind him.
"Start testing."
"Ok!"
Director Zhang nodded and immediately followed suit.
Originally, the inspection was scheduled two days later, but because Starry Sky Technology was ready for the next launch, the space agency was pressing harder, so all work was advanced.
However, Sun Yuanpei, who is an engineer on the space station, is not worried that the design of the entire Moon Palace core capsule can be said to consolidate the most advanced technology of the entire Hangke Group, and is improved on the basis of the Tiangong core capsule.
Soon, the core capsule was sent to the vacuum chamber, suspended by four cables. As the gas in the vacuum chamber is gradually evacuated, the entire core compartment is already in an environment similar to outer space.
Immediately afterwards, the engineer in charge of the operation pressed the start button, and all the equipment except the solar panel on the core module was started. At the same time, the operating conditions of various components and various physical parameters were all reflected on the screen of the console. .
"Everything works!"
Standing next to Academician Yuan, Zheng Xiangdong, the vice president of Aviation Technology Group, breathed a sigh of relief, his tight expression stretched a smile.
But at this moment, Academician Yuan next to him frowned slightly.
"... somewhat wrong."
The heart that had not been put down for a long time just hung up again, and Zheng Xiangdong immediately looked at Academician Yuan and asked.
"Where can't it?"
Academician Yuan didn't answer directly, and said something for a while.
"Look again."
Zheng Xiangdong said nervously, "Don't scare me ..."
The launch mission will begin at the end of the month. If something goes wrong in this section, he cannot afford this responsibility.
Academician Yuan did not speak, and his eyes were still tightly locked on the screen.
Seeing that the big brother did not continue to speak, Zheng Xiangdong relaxed a little.
Maybe it is wrong to read it?
So comforting himself, he settled down and continued to look at the screen on the console.
ten minutes……
twenty minutes……
After half an hour, the mutation finally happened.
I saw that the temperature curves of the components that fluctuated upward finally showed a clear upward trend. According to the temperature-time function prediction, the temperature of the entire core compartment is rapidly rising, and will reach a critical value after 24 hours, and the antenna control element will first stop due to overheating.
Seeing this, a drop of cold sweat slipped over Sun Yuanpei's forehead.
At the same time, a terrible word came to his mind.
Hot build up!
Judging from the current trend of temperature rise in the spacecraft, the total heat output of the core cabin has obviously exceeded the heat dissipation load of the thermal control system.
Not only did Sun Yuanpei see this, other engineers and researchers in the laboratory also noticed something wrong.
The first member to respond was Academician Yuan, who saw him break the road immediately.
"Terminate the experiment! Pass in protective gas."
"Yes!"
The engineers in the lab quickly got busy.
As the airlock was opened, nitrogen gas flowed into the vacuum chamber, and the power of each component was turned off one after another, and the operating temperature of the core compartment was finally reduced.
However, none of the engineers in the laboratory showed a relaxed expression on their faces.
Especially Zhang, who was standing in front of the console, and Sun Yuanpei, the engineer in charge of the space station project, all had pale expressions on his face.
"Crap……"
Even if he didn't understand the technical problems, Vice President Zheng Xiangdong also saw something wrong in the atmosphere of the scene, and quickly looked at Academician Yuan who was standing next to him and asked.
"What happened?!"
Academician Yuan frowned, then shook his head, and briefly explained the sentence.
"So much trouble."
Although he did not take the entire spacecraft apart, he had probably seen it.
Obviously, the problem lies with the loop heat pipe in the core cabin.
This loop heat pipe is usually used as a cooling system for spacecraft, which transfers heat from electronic equipment to a heat sink by evaporating and condensing fluid, and releases it in the form of heat radiation.
If something goes wrong in this part, even if the other components are perfectly designed, it is useless!
There are only two ways to solve this problem. One is to remove the loop heat pipe and redesign it. Either at the expense of spacecraft performance, streamlining or even removing some high-heat equipment to reduce the total heating value of the entire spacecraft.
However, the problem has come. This stuff is not a work cabin, nor an experiment cabin, nor is it a node cabin, but a core cabin that serves as the heart of the entire Moon Palace space station! Its significance is equivalent to the "Dawn" functional cargo bay of the International Space Station.
Even if they want to dismantle some high-heat equipment, there is nothing left to dismantle.
However, if the entire loop heat pipe is removed and the cooling system is redesigned ~ EbookFREE.me ~ not only means that billions of RMB funds have been used, it also means that the entire lunar orbit space station plan will be affected.
Hearing the "big trouble", Vice President Zheng only felt that his hands and feet were cold for a while, and his sweat gradually oozed from his forehead.
The next launch mission will be at the end of the month.
Now the core module is ready to go to heaven, but did not expect that something went wrong at the critical moment.
If it is unusual, the problems that were checked out before the heavens can also be regarded as luck.
But now is an extraordinary period. The Ares project ’s life support unit has just been launched. The whole country is looking forward to the Moon Palace plan to fight for it, and the chain is dropped on the most critical core cabin.
If not, the entire 2021 launch plan has to be postponed ...
This responsibility is not something he can shoulder.
