Technological power starts with upgrading lenses

Although I have followed Kang Chi for so long, I have already known his speed, so I would not be surprised if I gave him an engine a week later.

But the three-month booster was directly tested...

Is this a bit too exaggerated?

"Where's the engine test?"

"Just do the actual test. Ground testing is a waste of time."

"..."

Yan Hui actually wanted to say that compared with the time spent testing the car on the ground, exploding in the air would only waste more time, not to mention the possibility of exploding directly on the ground...

Even if it’s not manned, it can’t be played like this, right?

"Isn't this... a bit too aggressive? Does Academician Fu know about this?"

Maybe he felt that the word "explosion" was too unlucky, so Yan Hui changed it to a more euphemistic term.

Kang Chi just looked at him with a smile: "What? You have no confidence in the engine I built?"

Yan Hui suddenly fell silent,

Mainly because I don’t want to be slapped in the face by my boss…

Okay, the boss can do whatever he wants.

Anyway, it was his rocket that blew up, and it was his money that burned. At most, I was just a higher-level worker, just doing my own thing well.

If you think about it this way, no matter how crazy the boss is, it seems to become much easier to accept.

Speaking of crazy,

Yan Hui began to seriously doubt whether Kang Chi had been stimulated by something and had to compete with the lunatic from Country M...

How did he know that Kang Chi really just felt that ground testing was a waste of time. After all, testing requires a high-altitude test bench. The company would definitely not be able to build it now, so it would have to ask the space agency to help.

And once the engine is handed over to them, the testing process will become more complicated...

After returning to his laboratory, Kangchi immediately began to solve the problem of hydrogen storage.

By analyzing the engine some time ago, Kangchi has determined that Tongtian No. 1 is an oxygen-fixing and hydrogen-fixing engine.

Compared with the traditional liquid oxygen and liquid hydrogen engine, it only has an additional device for atomizing solid fuel, and the pressure relief valve at the fuel inlet is more advanced and intelligent.

In fact, if solid hydrogen is to be used as fuel, this part of the device can also be placed directly in the output pipe of the fuel tank, but since the system has been integrated for him, it couldn't be better.

Therefore, the hydrogen storage technology he needs now has changed from liquid oxygen and liquid hydrogen to solid oxygen and solid hydrogen.

Among the hydrogen storage technologies currently mastered by mankind, although high-pressure gas has certain safety risks, it is already a commercially available technology.

Low-temperature liquids have matured in laboratories, but are still some way away from cost-controllable industrial mass production. They are currently mainly used in aerospace and military fields.

As for the more difficult hydrogen fixation...

In fact, they are all gimmicks.

Most of the so-called successful cases of scientific research institutions are basically innovative, using solid materials such as carbon-based materials, inorganic porous materials, and metal-organic framework compounds to absorb hydrogen. The technical principles and usage are actually somewhat similar to batteries.

So the 'solid' in solid hydrogen actually refers to the storage medium, rather than actually storing hydrogen in a solid form.

I feel like the person who chose this name was somewhat trying to confuse people and confuse people...

Although this hydrogen storage technology can be stored and discharged in an environment close to normal temperature and pressure, it has the advantages of high volumetric hydrogen storage density, reversibility, high cycle life, good safety, and high purity of hydrogen supply, and its market application prospects are also very good. ,

But because this thing adds a lot of solid materials, the amount of hydrogen it can store is not even as high as that of a high-pressure tank with the same volume and weight.

The hydrogen storage quality of high-pressure gas tanks is usually 3-5.5%, while the hydrogen storage quality fraction of solid-state hydrogen storage technology of rare earth alloys and titanium-iron alloys cannot even reach 2%.

So it is indeed possible to use this thing as an energy solution for short- and medium-range transportation, but it is obviously impossible to use it to build rockets.

What Kangchi wants is hydrogen storage technology that can truly store high volume energy density!

The idea of ​​upgrading this technology is also quite simple and crude.

Since he was starting from scratch, Kangchi didn't even bother to make a liquid fuel tank. Instead, he welded a steel cylinder and injected gas into it to create a hydrogen storage tank.

The next step is to upgrade the gas tank.

[Item: Ultra-high pressure and ultra-low temperature hydrogen storage tank]

[Manufacturer: Kangchi]

[Item level: 6 (full level)]

[Item status: intact]

[Item parameters: hydrogen storage mass fraction 21.6%, volumetric hydrogen storage density 265KG/cubic meter, storage space 5 cubic meters, volumetric energy density 37.584 GMJ/m, storage temperature -253°C, 24H energy consumption 6MW·h, power outage The maximum status storage time is 30 minutes]

[Analysis item: parsable]

[General experience: 8763435]

[Proficiency Points: 46]

Seeing the parameters on the panel, Kang Chi nodded with satisfaction.

The hydrogen storage mass fraction and volumetric hydrogen storage density are more than three times higher than traditional low-temperature liquid hydrogen, and the volumetric energy density is instantly twice as high as methane!

This means that for the same amount of hydrogen fuel, if this technology is used to store hydrogen in a solid state, the size of the rocket fuel tank can be reduced by at least three times!

At the same time, a smaller rocket volume can also reduce resistance and mass, increase strength and payload, and reduce losses and increase reusability. The benefits are simply not too many.

The only trouble is that Yan Hui has to modify the booster plan according to the situation...

However, Kang Chi, who had just been proud for a few seconds, immediately saw a system pop-up window:

[Warning! Warning! Warning! ]

[Please power on the hydrogen storage tank as soon as possible, otherwise the equipment will explode! ]

[Explosion countdown: 29:52]

Looking at the countdown that was still jumping, Kang Chi was frightened and his face turned pale, and he hurried to find the power interface of this thing...

"Click--"

More than ten minutes later, as Kang Chi plugged in the power cord, the explosion countdown in front of him finally disappeared.

Kang Chi was relieved immediately.

Damn,

Fortunately, his base basically has all the materials he needs, and the industrial robots are also very powerful. Even if Kang Chi finds that the power interface of this hydrogen storage tank is not universal, it is completely in time to build an interface converter on site.

Otherwise, this time bomb that has just been upgraded will probably have to be pulled outside to explode...

After dealing with the sudden shock, the next step is to follow the same method to analyze and expand the equipment.

Although the volume of this hydrogen storage tank is only 5 cubic meters, as long as the technology inside is thoroughly understood, it should not be difficult to manufacture a storage tank with a larger volume. Even if there is a certain degree of difficulty, the worst case scenario is to connect the containers in parallel and use quantity to solve the problem.

One morning after two weeks of staying at home, Kang Chi, who was having a tryst with Zhou Gong, was awakened by an alarm clock.

"Good morning, master. Today is May 13th. The weather is sunny and the outdoor temperature is 15 to 27 degrees Celsius. Do you have a special memo today? Do you need to play the recording?"

Hearing Bai Niu's broadcast from the speaker, Kang Chi immediately remembered what the memo was, so he shook his head and said, "No, help me call Academician Zhang Peirong."

"Okay, calling Academician Zhang Peirong..."

"Hello, Academician Kang!"

"Yes, it's me. If I remember correctly, did Tianwen-2 arrive at the 'swallow' area today?"

"Yes, in fact, at 11 o'clock last night, we officially discovered the swallow!" Although Zhang Peirong on the other end of the phone had been up all night, his voice still sounded very excited.

"Has it been discovered?!"

Kang Chi immediately got up from the bed after hearing this.
