Chapter 2713 Two Materials
"The first is to ensure the flexibility of the astronauts' activities, and the second is to keep warm!"
insulation?
Hearing Liu Zhidong's words, everyone was stunned.
They never expected that Liu Zhidong would say such a thing.
Shouldn't it be cooling?
Now what the hell is this insulation?
Forgive everyone for not reading enough, at this moment, they are all confused.
They never expected that Liu Zhidong would say such a thing.
insulation?
Why do you want to keep warm?
What we want is good heat dissipation!
"Professor Liu, shouldn't what we need now be heat dissipation? What the hell is this heat preservation?" Zhang Donglai asked based on the principle of asking if you don't understand.
He really couldn't figure out what was going on.
Liu Zhidong smiled slightly, but did not speak, but looked at Qin Luo.
"Professor Qin should be able to understand my intention of doing this?" Liu Zhidong asked with a smile.
intention?
Qin Luo guessed a little bit.
As far as Qin Luo thinks, Liu Zhidong should have thought of Leng!
"Professor Liu, did you choose the thermal insulation material because you thought of the absolute zero temperature in the universe?" Qin Luo narrowed his eyes and asked with a smile.
There is not only high temperature in the universe, but also absolute zero, which is more terrifying than high temperature.
Generally speaking, spacecraft, like satellites, are flying around the earth in a fixed orbit.
When it is on the direct side of the sun, the temperature will be very high, which can reach 400 degrees, but once it is on the back of the sun, the temperature will drop sharply, and it can reach minus 273.15 degrees Celsius.
A person can only persist for a few seconds in this environment before being completely frozen.
So in the universe not only need to cool down, but also need to keep warm!
Only when the cooling and heat preservation are suitable, can Huaxia realize manned spaceflight in the true sense.
"That's right!" Hearing Qin Luo's words, Liu Zhidong nodded solemnly.
"There are not only high temperatures in the universe, but also absolute zero. If only the problem of high temperature is solved, it does not mean that manned spaceflight can be realized!"
Cooling and heat preservation are indispensable. Only when the two complement each other can the experiment succeed!
Hearing Liu Zhidong's words, everyone nodded quickly.
Although they really didn't want to admit it, what they had to admit was that what Liu Zhidong said was the truth!
Extremely high temperatures and absolute zero temperatures do exist in the universe.
None of them, including Zhang Donglai, had thought of it before, but now they thought of it.
"So, does Professor Liu have any good suggestions?" Zhang Donglai asked sincerely.
Suggest?
To be honest, Liu Zhidong smiled, he didn't know what to use.
But after pondering for a moment, he said, "In the usual sense, there are roughly three types of thermal insulation materials."
"One is an inorganic thermal insulation material, the other is an organic thermal insulation material, and there are metal thermal insulation materials."
"Specifically, their effect is good. I really haven't tried it, but it doesn't matter. We still have time. If we start the experiment now, I think we can get the result today!"
There are only those three kinds of materials. If the materials are complete and everyone works neatly, the test of the three materials can be completed in a short time.
If all goes well, the results will be available within a day.
Three materials?What are those three materials?
