Hand rubbing nuclear fusion live in the wilderness

Chapter 343 Flaws of the Space Shuttle

The comprehensive inspection of space shuttle zero took two days.

In two days, Han Yuan used various instruments to scan all the parts of the space shuttle, and even disassembled some parts for testing.

Of course, this was the first time he had come down from the sky, so the inspections were naturally much more detailed and cumbersome.

If you go to the sky and do the inspection again, the process and retrieval steps you need to go through will be much less.

Although it took two days, the good news is that there is no major problem with the space shuttle as a whole.

However, two small problems appeared in the inspection results this time.

One is that the consumption rate of the liquid xenon working fluid is much higher than he calculated in advance, and there is a lot more.

According to pre-calculations, without launching satellites, a total of 3.36 tons of liquid xenon working fluid will be consumed for this test flight to complete a space flight according to the original calculations.

But after the aircraft landed, he detected through instruments and data that the amount of liquid xenon working fluid was only 0.28 tons.

When No. 4 took off, the total amount of working fluid it carried was [-] tons.

This means that this flight consumed 3.72 tons of liquid xenon working fluid, which was 0.36 tons more than the calculated data.

0.36 tons, or 360 kilograms.

This amount is quite a lot.

360 kilograms of liquid xenon is enough to consume a large space station for a year.

Huaguo's space station, which was only built and put into use in recent years, consumes only [-] kilograms of liquid xenon per year.

After confirming that there was no calculation error in this result, Han Yuan frowned.

Four hundred kilograms of liquid xenon is nothing to him who can exchange technology points.

Moreover, when the space shuttle was designed, the liquid xenon storage tank took this situation into consideration, and things like the storage tank have redundancy.

Not to mention the [-] kilograms of liquid xenon, even if there is one more ton, the storage boxes with redundant designs can be put in there, and there is no need for additional improvements.

But the extra consumption of [-] kilograms of working fluid meant that there was something wrong with his design and calculation.

As for where the problem came from, I don't know yet, this needs to be analyzed through the flight log in the magnetic storage.

Han Yuan speculated that it should have something to do with the orders he had preset.

He checked those wrong commands before, and after discovering seven in the previous two mornings, four more wrong execution commands were added between [-]:[-] am and the landing.

Although it did not affect the stable return of the space shuttle, there must be an error with his calculated value. If the backup command is activated, more liquid xenon will naturally be consumed.

However, two of the four erroneous execution orders occurred after the space shuttle entered the stratosphere at an altitude of less than 160 kilometers.

This means that only two alternate commands consume liquid xenon.

And the two backup commands consume more than 360 kilograms of liquid xenon. Is this a bit too much?

Won't be sure, but suspect that some of the excess liquid xenon was consumed somewhere else.

The quantity consumption of liquid xenon is exceeded, which is the first small problem.

The second problem is a little more serious.

Under the protective material of HY-type aluminum oxide laminated material, he used a compound called 'polyhydrogen chloride grease' to serve as a direct temperature insulation layer between the surface layer and the solar power generation panel, and to obtain a certain cooling effect.

But it doesn't cool/insulate as well as it should.

This material is a highly transparent chemical synthetic material.

Has a strong ability to absorb heat and heat radiation diffusion.

According to the data calculation, after the temperature is lowered once by the thermal insulation properties of the HY-type aluminum oxide laminate material, and then the temperature is lowered by polyhydrogen chloride, the temperature reaching the surface of the lanthanum gallium silicon solar film should be reduced to below [-] degrees. .

However, the temperature detector arranged on the surface of the power generation board detected a high temperature exceeding [-] degrees.

And the records show that not only once, but three times.

However, these three high temperatures are distributed in different places.

Although the high temperature of [-] degrees is still within the range of the lanthanum gallium silicon thin film solar power generation panels, it is already a safety hazard.

Because I am not sure if [-] Baidu is the limit, if not, it may be exceeded.

At that time, it is the underlying solar panels that will be damaged.

In this case, South Korea has prepared two plans, one is to re-test the polyhydrogen chloride material to reconfirm the properties and heat radiation capabilities of this material.

The other hand is to replace the temperature insulation and cooling material of the middle layer.

Both problems require analyzing the log of the space shuttle, and Won no longer delays, and goes straight to the computer room after checking the space shuttle.

A magnetic storage device removed from Space Shuttle Zero is connected to a computer.

The finger keys are fast, and the calling commands line by line are continuously input into the integrated chip computer.

With the confirmation key pressed, a frame similar to txt text is opened.

Inside is a densely packed logbook, full of combinations of Chinese characters and numbers.

For the vast majority of viewers in the live broadcast room, this is something that can be understood at a glance.

But for experts and scientific research scholars in other countries, this is not very friendly.

Although the emergence of Chinese programming and ternary low-level codes has set off a wave of Chinese learning in countries all over the world.

However, Chinese is a thing that has not been cultivated in a large-scale and long-term environment. It is really difficult to learn it well in a short period of time.

Although the densely packed Chinese characters made one feel dizzy, experts from all over the world tried their best to widen their eyes.

Want to recognize every Chinese character on the live video.

However, within 30 seconds, more than 90.00% of the experts gave up.

"God, is this really human recognizable?"

"Can you go slower?"

In a laboratory in the United States, an aerospace expert who has not given up tried hard to widen his eyes, trying to confirm and analyze some useful information from the center.

But unfortunately, he failed.

The speed at which Han Won flips through the diary, not to mention foreign experts who have only learned Chinese for more than a year, even native Hua people, may not be able to surpass his speed.

Basically, he flipped through a page in less than five seconds.

You must know that there are almost 600 characters on this page, and it is completely different from ordinary reading.

Ordinary books are divided into sections, and there are various character help.

However, in the logs parsed on the display screen, the Chinese characters are densely piled up without any intervals or symbols at all, which is quite laborious to read.

However, in this case, the Korean won can still be kept for five seconds to turn a page.

In this case, not to mention foreign experts complaining, even our own people have to complain.

"This speed of flipping through, do you have a photographic memory?"
