Chapter seven hundred and forty-seven Reasons
Five engineers from Dragon Totem went back and forth with the No.33 detector crew to check the data and repeatedly played the detector video data.
Chang Haitao, the mechanical engineer of the engineering team, and Wang Anmin, the team leader, once again activated the camera of the Mars 33 probe car through remote control.
Two of the six car cameras are provided with rotatable mechanical arms.
Through the robot camera, they carefully checked the radiator of the car nuclear pool again.
After careful observation and feedback, the video Chang Haitao’s eyes were a little indecisive, and he picked up the technical instruction manual to review some data on the radiator.
Soon he found some doubts and turned to the dragon totem engineer and asked, "Is the radiator plate of Zhao Gong thermosyphon gray?"
Engineer Zhao nodded his head as soon as he was stupefied. "The radiator plate of thermosyphon radiator is gray when it leaves the factory. All the radiator plates of our company are gray. Is there any problem?"
"Gray? What about the specific color number? " Chang Haitao may feel that he is not very accurate and organizes the language again.
"I mean the color of the radiator. What color will it appear in the Martian environment?"
The real problem is not to find fault casually, because there will be some differences in the colors of the two specifications and materials, such as Tai, Blue Star and Mars.
This is because the light reflected from the surface of different environmental objects will be different.
Mainly due to the difference of atmospheric concentration, atmospheric composition and light intensity.
That is to say, the blue star of the radiator plate is indeed gray when it leaves the factory, but it may not be gray when it is on the surface of Mars. Even if it is the same gray, it may be slightly different.
Engineer Zhao thought, "This is a problem worth studying. We can look at some radiators that have not failed yet and compare the chromaticity of them to see if they are different."
Wang Anmin immediately joined him in charge of the Mars probe team and soon got a photo of the radiator plate of the detector.
In order to reduce the error, he specially selected a detector surface radiator with the same model as No.33 detector.
Then, after careful comparison, Chang Haitao and Engineer Zhao will find some clues.
Although the color of the fault radiator of detector 33 is also gray, the color is darker.
The color of the radiator plate of his detector is gray
"Could it be that the terrain of Sailor Grand Canyon caused the sun to be blocked?" An engineer said uncertainly 2.
Engineer Zhao shook his head. "There is no reason why the latitude and longitude of detector No.26 and detector No.3 are not much different from those of detector No.33. Besides, I saw that there is no significant difference in the light intensity of each detector."
"That is to say, the color of No.33 radiator plate may be caused by abnormal conditions." Chang Haitao made a preliminary conclusion.
But what is the situation?
Everyone is still puzzled. After all, the surface of the radiator plate is coated with a high-strength nano-film, not to mention the Martian sandstorm. Even if a big stone directly hits the surface, there will be no scratch.
At that time, these detectors were designed to increase reliability by using simple and rough thermal materials to reduce mechanical failures and interference problems.
While everyone was thinking hard, another bad news came back from Mars 33 at about five o’clock the next day.
The radiator efficiency showed a slow decline half an hour ago, and when the cut-off message was fed back to Blue Star, the radiator efficiency had dropped to 62%.
You know, according to the design life of Dragon Totem Company, the average annual reduction efficiency of this type of radiator will not exceed 2%.
Even in the harsh environment, the reduction rate should not be higher than 5% per year.
Now probe 33 has only been working on Mars for more than a month, and it hasn’t even arrived for a year.
What’s more, this is a spare radiator.
"What is this?" Wang Anmin look dignified.
The cause of the failure of the first radiator has not been found out yet, and now the other standby radiator is also out of order, which makes everyone in the working group feel a sense of saving the day.
After all, if the detector nuclear pool can’t dissipate heat, it is easy to burn roads and parts, which will lead to the direct paralysis and scrapping of the detector.
As time goes by, the super brain of car 33 keeps feeding back the situation.
Finally, one hour later, the effective heat dissipation efficiency of No.33 standby radiator has fallen below 2%
Even if the emergency system is started and boron-carbon buffer is inserted to slow down the nuclear decay of the nuclear pool, it is difficult to restrain the slow rise of the core temperature of the nuclear pool body.
"Damn it! What went wrong? " Chang Haitao grabbed his hair and thought about it with a headache.
Wang Anmin, who felt that things were out of control, quickly reported the matter to the space department, which once again organized an expert group to help analyze it.
Two days later, the core temperature of the nuclear pool of detector 33 is getting higher and higher, and if it is not treated, it will affect other components.
It is forced that the working group can unload the nuclear pool and start the salt preparation nano-storage pool by remote control to fold the solar pool board.
Although the loss of the nuclear pool caused the daily availability of No.33 to drop to about 15%, No.33 was not directly scrapped.
At this time, the Dragon Totem engineer is also puzzled, and he can’t understand where the radiator failure problem of No.33 detector is.
