Spark

Two days later, Chen Nian returned to Chengdu.

The foundations of the superconducting industry and the fusion industry have been basically established, and a series of downstream industries and derivative technologies will be developed next.

Regarding this point, Chen Nian was not in a hurry.

In fact, even with Huaxia's mature technology accumulation and strong mobilization capabilities, it is impossible to fully roll out these two new technologies in a short period of time.

His own psychological expectation is 10 years.

Within 10 years, the comprehensive replacement of most technical fields will be realized, and the penetration rate and coverage rate of primary achievements will reach 100%.

On this basis, the transformation of the entire social form will be completed within 20 years. By then, the entire China will truly enter the fast lane.

Sitting in his office, Chen Nian let out a sigh of relief.

Sure enough, I don't know when I started to get used to living in this city.

Although his movement track is the three-point line of the office, home, and laboratory all year round, as soon as he returns here, he feels a sense of security that he is protected.

This feeling certainly has nothing to do with protection in the true sense of the word, but rather some sort of psychological comfort zone.

It seems that it's time to bring the parents over? ——

Forget it anyway.

The last time they called, they were urging the marriage, so living together might be even more troublesome.

The revolution has not yet succeeded, how can I talk about the love between children?

Thinking of this, he sat up straight again, and said to Chen Guo who was on the sofa:

Professor Chen, please help arrange Qiao Mai's affairs. She plans to go to Qatar. If necessary, give her some convenience.

Don't worry, it's already arranged.

Chen Guo nodded and answered.

In fact, in his mind, Qiao Mai was a good way to solve Chen Nian's personal problems, but after several trials, he also confirmed that Chen Nian had no such idea for the time being, so even if it was mentioned in the conversation, he would not Will not know how to extend the topic.

That's fine. Qiao Mai is quite talented in the field of hydraulics. I estimate that in another ten years, she may become a technical leader in the field.

When she is young, let her exercise more, and give her the resources she needs.

Hearing Chen Nian's words, Chen Guo couldn't help laughing.

You're so old-fashioned!

Seriously, when you guys met at AH, wouldn't that be the same way you talked to her?

That's not enough.

Chen Nian quickly waved his hand.

Although many people always like to describe academic masters, scientific researchers, and science and engineering geniuses as some kind of image of high IQ, low EQ in the prejudice of many people, but in fact this is not the case at all.

What is emotional intelligence?

In fact, it is nothing more than the degree of understanding of the logic of human relationship, which itself is also traceable and theoretically supported.

Can people with high IQs not understand this kind of thing?

At least Chen Nian himself could understand.

Therefore, even without the experience of the previous life, it is impossible for him to do things like show off in front of others.

That's good. After all, you are friends first and then comrades. There is no need to be too unfamiliar with each other.

I know -- let's not talk about this, I received a message on the way back, saying that Lao Mei is going to restart the lunar exploration plan?

Chen Guo nodded immediately, and replied:

Yes, the gossip has just been released, and the official has not officially announced the plan.

But there is a high probability that they are playing for real this time, and their goal is very clear, which is to go for Helium 3.

Chen Nian frowned slightly.

Using helium 3 to replace deuterium as a fusion reactant is not such a bizarre idea. In fact, after the fusion theory was born, the academic community generally believed that helium 3 was a more suitable reactant than deuterium.

The reason is simple. The fusion reaction between helium-3 and helium-3 is a more efficient fusion process, and the energy released by the reaction is much higher than that of deuterium-deuterium fusion.

At the same time, the number of neutrons produced by helium-3 fusion is small, and the relative energy loss is also low, which has great advantages in controlling radiation loss and material damage in the reactor.

There is actually only one reason why it has not become a mainstream research direction:

The stock of this thing on the earth is too low, but it is abundant on the moon.

Under the current technological environment, it is difficult for human beings to maintain the operation of a near-Earth space station, let alone realize commercial transportation for landing on the moon.

Of course, for China, this is an inevitable step.

In the future, whether it is to use a space elevator or use a large-scale air platform as a springboard for multi-stage launches, it is a feasible solution.

But old beauty? ?

In the absence of room-temperature superconducting materials, it seems a bit too farfetched for them to go to the moon on a large scale.

Do you think they can do it?

Chen Nian asked.

It's hard to say. After all, they have already done it decades ago. Whether it is aerospace, electronics or machinery, technology has been greatly improved. If they want to copy it again, I'm afraid they can't do it again. It will be too difficult.

The only problem is that going to the moon is a very proprietary technology -- or what we call a specific technology.

The specific technology itself is very easy to be lost, and their complete system for manned moon landing did not meet the standard of 'mass production' at all.

Not to mention that more than 40 years have passed, even in the 1980s, when all their technicians were still alive, the moon landing technology was actually on the verge of being lost.

If they want to do it again now, in one sentence: there is no homework to copy, and they start all over again.

After Chen Guo finished her judgment, Chen Nian on the opposite side also nodded in agreement.

It's the same as mine.

Going to the moon with a cannon and going to the moon with a rocket, after all, the technical path is still different.

But having said that, what was the result of their moon landing?

We believe they have achieved good results.

Chen Guo replied ambiguously.

.All right.

Chen Nian didn't continue to ask, but he clearly remembered that in his previous life, the Yutu-1 lunar exploration rover designed according to the old American standard had suffered a lot on the surface of the moon.

It was not until the replacement of domestic technology was adopted that Yutu No. 2 went on smoothly.

At least from this perspective, it is not appropriate to copy their experience.

In any case, they decided to start the moon landing plan by themselves, which means that our previous plan to exchange a part of nuclear fusion technology for the other party's full set of aerospace industry achievements has gone bankrupt, right?

They have only a few chips left in their hands, and they still plan to gamble to the end, which really shows their nationality to the fullest.

Chen Guo shook her head amusedly, and replied:

It's not that exaggerated. According to their current level, it will take two to three years at most to land on the moon and return.

Not only are they not gambling, but they are quite cautious.

After all, within two to three years, our aerospace industry will not be able to reach their level. If they fail by then, there is still room for repentance.

there is none left.

Chen Nian interrupted Chen Guo's words.

In two to three years, it is indeed impossible for us to achieve a comprehensive breakthrough in aerospace technology, but it is not difficult to come up with one or two typical projects.

After all, it's just the last moon. It's not too difficult.

After seeing off Chen Guo, Chen Nian did not leave the office immediately, but followed the topic just now, and immediately started sorting out the technologies needed for the lunar exploration project.

In fact, he was not bragging when he said that there is nothing difficult about going to the moon. Don't say that there is a big killer of the system now, so what if there is no system?

In the last life, Huaxia launched the Chang'e-1 lunar exploration satellite for the first time in 2007, and then launched Chang'e-2 and Chang'e-3 in just 6 years, and successfully achieved the first soft landing on the moon.

That was 2013, only 6 years after the launch of the first lunar exploration satellite!

In this life, the progress of the Huaxia lunar exploration project is faster than in the previous life. The launch time of Chang'e-2 was brought forward to the end of 2009, and the main construction and preparation work of Chang'e-3 project has been completed more than half.

If all goes well, the moon landing can be realized from the end of this year to the first half of 2013.

So, in this case, to the moon is not really a question at all.

The problem is how to go to the moon and bring back enough samples to prepare for subsequent large-scale mining.

In this process, the core actually consists of two parts:

The first is the implementation problem, what kind of technology should be used to send heavy detection and mining equipment to the moon and ensure that it can return smoothly.

The second is the cost issue. What kind of equipment should be used to keep the round-trip cost as low as possible.

For the previous question, Chen Nian actually didn't intend to spend too much time and energy.

After all, if you work hard to make a miracle, metal hydrogen is not only a superconductor, but also an extremely terrifying energetic material.

Coupled with the technology accumulation of the previous TBCC engine, new engine + new fuel, it is not a big problem to send a small excavator up.

The key lies in the cost part.

The purpose of going to the moon is to dig helium 3, and the purpose of digging helium 3 is to improve the efficiency of the fusion reactor.

And if the cost of mining is higher than the benefits of increased efficiency, it is simply not worth the candle.

Chen Nian tapped on the table lightly, thinking about possible technical routes.

According to his experience, there are only a few technologies that can achieve large-scale reduction of aerospace costs in the short term, mainly in the directions of rocket recovery, space shuttle, high-altitude assisted launch, magnetic ejection, and high-altitude aircraft capture.

Among them, rocket recovery was the most mature in the last life, and it fits the most with the existing technical route. There is no doubt that Chen Nian put it on the highest priority.

As for the space shuttle, after the rocket recovery technology, it should be said that it is relatively tasteless, but it happened that the TBCC technology was selected in advance in China, which led to the prospect of the space shuttle suddenly becoming broader.

As for the high-altitude auxiliary launch, the original route of this thing is to use high-altitude balloons to assist the launch. It has become the most imaginative technology.

Followed by magnetic ejection, superconductor + electromagnetic track technology gave it room to realize.

High-altitude aircraft capture --- large transport aircraft, TBCC engine laid a technical foundation.

Looking around, every direction is actually a good direction!

Chen Nian couldn't help but support his forehead.

It's okay not to tidy it up, but after sorting it out, he realized that in less than 10 years, the foundation laid by Huaxia is really stronger than he imagined.

Choose phobia, who knows?

I'm afraid Lao Mei doesn't have such troubles at all.

After hesitating for a long time, Chen Nian did not finally decide on the direction. What's more nonsense is that the core equipment corresponding to these directions has the same number of source points required for analysis in the system, and they all fluctuate around 500 points.

There is no way to choose.

He sighed, leaned his head back on the chair, and thought to himself:

Why don't we just build a space shuttle, and open the space route in advance, so that we can go to space to see it by ourselves in the future

But I still want to engage in high-altitude assisted launch.

Big is good, floating island is a man's romance, okay?

Can the Nantianmen project hurry up?

Just as he was struggling silently in his heart, there was a sudden knock on the office door, and then, Li Xiang pushed the door open and walked in.

Seeing his frowning look, Li Xiang asked curiously:

What's the problem?

Chen Nian shook his head and replied:

There is no problem, there are too many choices, and I can't choose.

He briefly explained his considerations to Li Xiang, who also couldn't laugh or cry.

You are really cheap and good-looking. But seriously, since other technical routes have already been accumulated, why don't you just open a new route?

New route?

That's right, if you engage in individual things, and the technologies don't overlap, maybe you can also stimulate the development of other directions.

Hearing what Li Xiang said, Chen Nian also recalled it.

Indeed, a good idea.

But the question is, what are you doing? !

Then what are you talking about?

Chen Nian looked at Li Xiang with piercing eyes.

He is not afraid that the other party will come up with wild ideas, but he is afraid that he has no imagination.

After thinking for a moment, Li Xiang said:

Actually, I have been wondering why the initial velocity of the rocket launch must be so high.

According to the intuitive feeling, as long as the downward thrust is greater than the gravity, I can fly to space by hanging myself with a drone, right?

That's right.

Chen Nian nodded and replied:

Theoretically, as long as the thrust is enough, you can climb to the moon even at the speed of an ant.

The reason for the high speed is that it must break through the first cosmic speed—you can think of rockets as cannonballs, and you don't care about them when you shoot them out. It's easy to understand.

However, the current rocket launch is not a one-off deal. It needs to go through multi-stage acceleration in the middle?

Chen Nian's eyes lit up, and he suddenly understood what Li Xiang was thinking.

And Li Xiang also took advantage of the situation and said:

So it is also feasible to change this acceleration process to a constant speed?

Isn't Chengfei ready to engage in electric aviation development projects? Can this stuff work?

Chen Nian nodded sharply and replied:

There's something wrong!

At this time, a picture that he had never imagined before appeared in his mind:

An aircraft carrying solar panels and metal hydrogen batteries slowly lifts off from the roof of a residential building, then slowly climbs into space at a speed of one meter per second. After entering outer space, it ignites a small firework rocket and sends itself into the outer space. space

This screen can be further optimized.

After helium 3 is collected on a large scale, it will no longer be difficult to miniaturize the fusion reactor.

If you can come up with a non-propellant engine, it will really be a new era.
