(There is another chapter, a little later)

After deciding to make the 096 project a short-term priority, Chen Nian also began to fully participate in the project.

In fact, the research and development work on this strategic weapon in the true sense has already started, but until now, the design of the hull has not been completed.

This is of course not because of the laziness of the R\u0026D personnel, but because, after entering the specific system design, what they consider is not just the deduction at the "concept" level.

A slight change in the angle of an arc on the hull may correspond to an increase or decrease in the capacity of several missiles inside.

The brand-new integrated power system also brings new challenges to the internal layout.

In addition, the comprehensive noise reduction scheme designed by Chen Nian involves multiple technologies such as floating raft vibration reduction, noise reduction tiles, integrated electricity + shaftless pump thrust, propeller fairing, and each technology has its own special difficulties.

The most typical one is the floating raft vibration reduction technology. Although it looks simple, it is just a set of flexible connection technology, but in fact, only the rubber connectors, hydraulic and cable mechanical Several key parts of the truss structure require extremely high mechanical and material foundation support.

In addition, the entire floating raft vibration reduction system must be coordinated with the internal equipment layout, and the damping treatment, stiffness and reasonable layout, and impact resistance must also be planned uniformly after complex model simulation.

Although there are no difficult technical barriers in these steps, it does take a lot of time to try and make mistakes one by one.

At the beginning, Chen Nian planned to let the 096 project team explore on their own. After all, the process of exploration is also a process of training and training personnel capabilities.

But now, in the face of unknown threats, the importance and urgency of the 096 project has suddenly been raised a lot, and Chen Nian can't wait for them to try slowly.

Therefore, he used the system again and conducted a secondary analysis on the original basis. It took 21 sources to sort out all the technical parameters and send them to the project team at one time.

So far, the problems of the whole set of noise reduction system have been completed. Next, it is necessary to start building the hull model and verify the hull structure.

The core content of this part is the same as the original 055 project, which is the layout of the vertical hair system.

However, compared with the "simple and direct" 055, the 096 vertical hair system must also consider the problem of large pressure-resistant hulls.

According to the current design, the diameter of the 096 pressure-resistant shell needs to be at least 16 meters in order to solve the most difficult problem of large turtles.

But to achieve this, the production technology of super-strength alloys has become the top priority.

Therefore, a field that seems to have nothing to do with submarine manufacturing must be considered at a strategic height.

That is, rare earths.

Chen Nian can confirm this point without systematic information. After all, the Ti-6Al alloy currently used by Huaxia has achieved significant results in the manufacture of deep submersibles. According to the progress he saw in his previous life, adding rare earth After adding elements, the tensile strength of Ti-6Al will be significantly improved, and it will undoubtedly become the most suitable hull material.

As for the question of cost.

Titanium alloys are indeed expensive, especially in submarines, which often use tens of thousands of tons of materials.

However, Chen Nian asked himself, after several years of leapfrog development, and under the premise that a lot of funds and resources have been saved in many military equipment and large-scale projects, it is not difficult to maintain several titanium alloy nuclear submarines.

Old men can afford it, can't we afford it?

Therefore, Chen Nian did not intend to continue to follow the route of high-strength steel from the very beginning, but directly analyzed the industrial preparation method of Ti6Al4V-0.3Y, which is the improved TC4 titanium alloy.

In addition, he also presented a SiC fiber-reinforced titanium-based composite material scheme for the project team to selectively use in specific manufacturing.

Of course, this kind of fiber-reinforced composite material is more complicated in terms of cost and manufacturing process. It must be prepared by hot isostatic pressing equipment, and large-scale manufacturing is also difficult.

But as long as there is, there is one more choice.

As for which one to choose in the end, or how to use it together, it is a question of the specific operation of the project.

After the hull design problem was basically solved, Chen Nian turned to the power source without stopping.

The thorium-based molten salt reactor project, which has been approved for a long time, is progressing rapidly under the leadership of Lu Qingzhou's team from the Nuclear Power Research Institute, which benefits from their accumulated experience on the 216 reactor.

In fact, the weakest link of the 216 project is the design of the RPS system, but the requirements for the RPS system of the thorium-based lava reactor itself are relatively low. Coupled with the technical documents provided by Chen Nian, it can basically cover 80% of unfamiliar areas. Therefore, on the research and development path of the fourth-generation reactor, many key technical obstacles have been virtually eliminated.

——

Of course, the resolution of this technical obstacle refers specifically to the reactor design link, which includes corrosion control, circuit design, and structural material processing, which are directly related to the reactor equipment.

As for pre-technologies such as molten salt preparation, purification, dry separation of spent fuel, high-temperature electrolysis hydrogen production, etc., there is basically a blank in China.

Chen Nian also couldn't take care of all the links, so he chose the most complicated nuclear pure thorium preparation technology as a breakthrough point, using it as a fulcrum, intending to use the power of the Civil Affairs Office to open up all upstream technology channels.

He couldn't do this by himself, but needed Chen Guo to coordinate.

So, he found Chen Guo again and told him all about his technical layout.

Chen Guo was stunned when she heard it - you know, it's been less than two days since the last time they met

And in these two days, Chen Nian can almost be said to have done things that many people can only do in a lifetime.

".So you haven't slept at all these two days?"

Looking at Chen Nian's thick dark circles, Chen Guo asked.

Of course he knows that Chen Nian is a genius, and he also knows that he must have some secrets that are temporarily inconvenient to disclose, but even with the blessing of these elements, it is obvious that Chen Nian is already a little overdrawn.

After all, in such a short period of time, the upstream and downstream technologies of a new piece of equipment have been sorted out, and most of the technical problems involved have been solved. Just thinking about it is incredible.

Don't even think about it, the answer is in front of you, you can't copy it so fast, can you?

Hearing Chen Guo's worried tone, Chen Nian quickly waved his hands and replied:

"I'm asleep, I haven't slept for long."

"It's normal to not sleep well when you're stressed, don't worry too much."

"You first distribute all these technologies according to my requirements, and arrange the follow-up project work."

"We have to move fast, or else."

"But the problem is that things like nuclear submarines can almost be said to be the last resort for nuclear counterattacks."

"If you can use it, the world is basically over-is it really possible for this kind of thing to happen?"

Chen Guo's tone was puzzled, Chen Nian frowned and shook his head, and replied:

"I'm not sure, I just know that the situation may develop in the worst direction, so I have to prepare for the worst."

".Understood, you need a sense of security."

"Almost. By the way, what is the superior's judgment?"

Chen Nian asked.

"It's still under discussion. Judging from the current macro situation, there are no obvious signs of crisis."

"On the one hand, the risk of a large-scale hot war is very low; on the other hand, we have an overall advantage in economic confrontation-although there is still a considerable gap in overall volume, we have already surpassed in terms of increment. "

"In addition, the overall domestic social environment tends to be stable, internal conflicts are weakening, and local governance capabilities are constantly improving. To be honest, in this case, even if there are risks, they will not have too much impact on us. .”

"Because at this stage, we have a strong ability to resist shocks and a high fault tolerance rate."

"So, don't put too much pressure on yourself - our situation is certainly not safe, but it should not be as dangerous as you think"

Chen Nian nodded slightly, but did not speak.

Intellectually speaking, he also agrees with Chen Guo's judgment.

But intuitively, he couldn't really relax himself.

He sighed lightly, and after thinking for a moment, he said:

"Let's not care about that much, no matter what, we always have to prepare in advance."

"However, in terms of macroeconomics, there is one point that we need to make strategic adjustments."

"Which point?"

Chen Guo asked.

"Rare earth."

"After the technological environment has changed, the importance of rare earths is no longer the same as in previous years."

"My suggestion is that starting from this year, our own rare earths can no longer be exported outside the border."

"This is no problem. We have implemented controls since 2006, and we will tighten them in the short term, and the pressure will not be too great."

"That's good."

Chen Nian nodded slightly.

He still remembers the "great defeat" suffered by China's rare earth industry before 2006 in his last life.

Although the defeat was recovered through various means, and even the initiative was regained after a period of time, but it has to be said that the losses that have been caused are irreparable.

Fortunately, in this life, due to changes in the economic environment, the economic benefits provided by rare earth exports have also weakened accordingly.

In a way, our actions are much more decisive than in the previous life.

The same problem, although I did not take the initiative to interfere, was still avoided. This is probably the so-called butterfly effect.

The only thing Chen Nian hopes is to have more positive butterfly effects like this.

On the other side, Li Xiang sat in front of the computer, carefully reading every piece of public opinion data that came out of the system.

After Chen Nian's judgment was reported, he acted immediately like all other relevant personnel and began to investigate all possible risks.

However, although he belongs to the intelligence department, he is actually more responsible for the work of public opinion, so when facing a problem, his first thought is to start from this aspect.

In the past two days, he has compiled the directories and data of all agendas on the Internet in the past two years, including forum hot content, important news of the year, internal core comments, and all key intelligence information that can be queried by his authority .

Then, he analyzed the information one by one, intending to give priority to excluding the "absolutely irrelevant" parts.

The first thing to be ruled out was the news about the earthquake, and while this agenda did cause a lot of discussion around the world, its nature dictated that it could only be a completely independent random time from beginning to end, without anyone It can be used, and it will not be related to any macro situation.

The second thing that was excluded was a series of topics whose influence had ended, including topics caused by various new equipment in Huaxia.

Although these devices are still spreading their influence and slowly changing the world, the "topic" itself has no reference value.

Immediately afterwards, he relied on his own understanding to rule out some topics that theoretically had little impact on China.

Among them, "independent conflicts" between countries in the Middle East are excluded, and changes in the situation within Africa that do not involve China are also excluded.

After doing all this, he reclassified the remaining topics, and finally summed up several most representative and hottest agenda items.

After seeing the result, Li Xiang suddenly had a complicated emotion in his heart.

No, it wasn't anxiety, nor was it the "angry" emotions that he often had when he first joined the intelligence service.

It's pride with a hint of doubt.

What makes him proud, of course, is the content shown in the topic list.

"The crisis in Khartoum is lifted, and China may play a major role."

"Sanctions have failed, and semiconductor and communication companies have collectively gone to sea."

"Two more islands are added to the sea, which can take off and land heavy transport aircraft and bombers."

"The US-Japan alliance broke down, and Europe was captured by Huaxia Corporation?"

"The aircraft carrier battle group is withdrawn, and 055 is unimpeded."

"Massive influx of talents, Huaxia may become what the people want?"

One piece of news, each one tells the great changes in China in recent years, and also shows the alternation, increase and decrease of the strength of China and the United States.

Make no mistake, the news is all good.

But what he doubts is, are we really so strong?

He vaguely felt that from top to bottom, from the public to the government, the self-confidence seemed a bit too strong.

In particular, after seeing a recent hot comment that skyrocketed that day, his anxiety became more and more intense.

The headline of that news read:

"The best time, the best opportunity."

What it is telling is self-evident.

This is not an official comment, but it has received as much recognition as any official message.

What does this mean?

This means that among the people, the voices on this matter have reached the level of "all expectations", and his superior, China's public opinion supervision department, has not deliberately guided and controlled it.

So do you really want to do it?

Li Xiang frowned tightly. After thinking for a while, he picked up the phone and dialed Chen Nian's number.

After the call was connected, he said bluntly:

"Grandma Chen, I have an idea."

"Could it be that what you're worried about has something to do with South Island?"

Chen Nian on the other end of the phone was silent for half a minute, until Li Xiang thought the phone had been hung up, and finally heard his answer.

"I see."

"I guess I know what's going on."

"Is it really South Island?"

Li Xiang asked in disbelief.

"Yes, it's not a meeting to talk."

"There are several key signals that need to be verified."

"If all of them are confirmed, then the fun will be great"
