Chapter 444 Hydrogen Storage Tank

Although I have been following Kang Chi for so long and already know his speed, I am not surprised to be given an engine a week later.
But the three-month booster was tested directly...

Isn’t this a bit exaggerated?
"What about engine testing?"

"Just do a direct test. Ground test is a waste of time."

"..."

Yan Hui actually wanted to say that compared to the time spent on the ground test run, the time wasted in the air explosion would only be greater, not to mention the possibility of exploding directly on the ground...

Even if it's not carrying people, you can't play like this, right?

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

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

Kang Chi just smiled and looked at him: "Why? You don't have confidence in the engine I built?"

Yan Hui fell silent.
Mainly because I don't want to be slapped in the face by my boss...

All right, boss, whatever you want.

Anyway, it was his rocket that exploded, and it was his money that was burned. At most, I am just a high-level worker, and I just need to do my own job.

If you think about it this way, even the craziest boss seems a lot easier to accept.

Speaking of madness,

Yan Hui began to seriously suspect that Kang Chi had been provoked by something and had to compete with that madman from Country M...

How could he know that Kang Chi simply thought that ground test driving was a waste of time. After all, a test drive requires an aerial test bench, and the company would definitely not be able to build one in time, so they had to ask the Space Administration for help.

Once the engine is handed over to them, the testing process will be very complicated...

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

Some time ago, through analyzing the engine, Kangchi has determined that Tongtian No. 1 is a solid oxygen and solid hydrogen 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 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 already been integrated for him, it is naturally the best.

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

Among the hydrogen storage technologies currently mastered by humans, high-pressure gas has certain safety risks, but it is already a commercially available technology.
Cryogenic liquids have already matured in the laboratory, but are still some distance away from cost-controlled industrial mass production. They are currently mainly used in aerospace and military fields.

As for the more difficult solidification of hydrogen...

In fact, they are all gimmicks.

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

So the "solid" in solid hydrogen actually refers to the storage medium, not the actual storage of hydrogen in solid form.
I feel like the person who chose this name is somewhat confusing and trying to fool people...

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

However, because this thing contains a lot of solid materials, it can store less hydrogen than a high-pressure tank of the same volume and weight.
The hydrogen storage mass of high-pressure gas tanks is usually 3-5.5%, while the hydrogen storage mass fraction of solid-state hydrogen storage technology of rare earth alloys and titanium-iron alloys does not even reach 2%.

So this thing can indeed be used as an energy solution for medium and short-distance 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 upgrade idea of ​​this technology is also quite simple and crude.
Since he was starting from scratch, Kang Chi didn't even bother to make a liquid fuel tank. Instead, he welded a steel cylinder and injected gas into it, directly making 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: Kang Chi]

[Item Level: 6 (Maximum Level)]

[Item status: intact]

[Item parameters: hydrogen storage mass fraction 21.6%, volume hydrogen storage density 265KG/cubic meter, storage space 5 cubic meters, volume energy density 37.584 GMJ/m, storage temperature -253°C, 24H energy consumption 6MkW·h, maximum storage time in power-off state 30min]

[Analysis item: parsable]

[General experience: 8763435]

[Mastery Points: 46]

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

The hydrogen storage mass fraction and volume hydrogen storage density are more than three times higher than traditional cryogenic liquid hydrogen, and the volume energy density is instantly twice as high as methane!
This means that with the same amount of hydrogen fuel, if this technology is used for solid-state hydrogen storage, the volume of the rocket fuel tank can be reduced by at least three times!
At the same time, a smaller rocket size can also reduce resistance and mass, increase strength and effective load, reduce losses and increase reuse rates. The benefits are simply too numerous to mention.
The only trouble is that Yan Hui has to modify the booster plan according to the situation...

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

[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 ticking, Kang Chi was so frightened that his face turned pale, and he hurried to find the power port of this thing...

"Click——"

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

Kang Chi heaved a sigh of relief.

Nima,

Fortunately, his base had basically all the materials he needed, and the industrial robots were also very powerful. Even if Kang Chi found that the power interface of this hydrogen storage tank was not universal, it was still in time to build an interface converter on site.

Otherwise, this newly upgraded time bomb 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 capacity of this hydrogen storage tank is only 5 cubic meters, it should not be difficult to manufacture a storage tank with a larger capacity as long as the technology inside is fully understood. Even if there is a certain degree of difficulty, the worst that can be done 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 the alarm clock.

"Good morning, Master. Today is May 5th. The weather is sunny and the outdoor temperature is between 13 and 15 degrees Celsius. Do you have any special notes today? Do you need to play the recording?"

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

"Okay, calling Academician Zhang Peirong..."

"Hey, Academician Kang!"

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

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

"Already discovered?!"

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