A few days later, Mizutani Hayabusa of the Kawasaki Group arrived in China as a representative of the carbon fiber complex.

Subsequently, in a very short period of time, the two parties reached an agreement on the introduction.

Of course, what played an important role in it was the Indian high-speed rail order that Huaxia voluntarily sold.

After all, after China's withdrawal, Kawasaki Heavy Industries has higher bargaining power and can avoid the risk of malicious competition.

The potential benefits obtained from this are much higher than the benefits of "300 million orders".

That night, whether it was Huaxia or the island country, there was a happy and peaceful atmosphere.

It's just that what is concealed under this happy atmosphere is a huge crisis on the one hand, and unprecedented opportunities on the other.

In the office of Xigong University, Chen Nian looked at the copy of the contract in his hand with satisfaction, and said:

"Professor Chen, your operation is really beautiful this time!"

"There are 6 thousand-ton production lines, including 4 large tow lines. In the next ten years, we don't have to worry about our carbon fiber materials."

Chen Nian's words are not without basis. In his impression, Huaxia built the first 48k large tow thousand-ton production line around 2017 in his last life. Before that, most of the high-strength carbon fiber materials All rely on imports.

Now, with the initial "starting machine", the development of the subsequent carbon fiber industry will continue to accelerate.

This is not a small market.

Not to mention the rapid development of aviation and high-speed rail, there are too many civil products involving carbon fiber.

Automobiles, bicycles, construction, and all kinds of sports equipment, including carbon fiber fishing rods, which fishermen love, all need strong industrial support.

Before 2006, the import rate of domestic carbon fiber materials reached more than 80%, and the pitiful 20% were almost all low-end products.

A large amount of profits flowed overseas, which brought unnecessary losses purely due to "technical differences"

Hearing Chen Nian's words, Chen Guo on the opposite side smiled calmly and replied:

"We didn't expect it to be so smooth. Xiaotian was really dazzled by the orders from India, which made us a little hesitant, wondering if the projects in India were really that good."

"However, since things have been settled anyway, there is no need to think so much."

"This introduction can not only solve the urgent need of the H-20 project, but also revitalize the entire industry in the future."

"Preliminary estimates show that the economic benefits we can generate from this introduction should be more than 10 billion yuan, and the savings in foreign exchange will be even more."

"Based on 10 years, the total savings should exceed 100 billion."

"This money can be invested in more useful technical departments in the future."

Chen Nian nodded. From Chen Guo's words, he saw something different.

Perhaps whether it is on the Internet, among the people, or even in the eyes of some upper-level decision makers, engaging in some big projects and making some decisive equipment is the driving force for the rapid development of the country.

But in fact, what an old man said is very true:

Governing a big country is like cooking small fish.

Every spoonful of seasoning and every stir-fry may determine the taste and heat of the whole dish.

Only pennies and pennies must be taken carefully to get the benefit of every penny and accumulated, and only then can quantitative change lead to qualitative change.

This is true for the chip project, the Yishan project, and the current carbon fiber project.

Step by step, we have come a long way before we know it.

Maybe one day in the future, when I look back, I will find that the ordinary little things in front of me are actually the solid bricks and stones that make up the building.

Thinking of this, Chen Nian continued to ask:

"If the material problem can be solved, when is the H-20 going to take a test flight?"

"Mr. Tang's side is expected to be in early March next year, and there are still five months to go."

"Basically, it's about the same. The 'Nanling' project of the variable cycle engine has also come to an end, and the first test is expected to be completed within three months."

"However, it will take a certain amount of time to debug this engine before it can be used on the H-20. This time difference is just right."

Having said that, Chen Guo thought for a moment, as if she remembered something, and continued:

"Mr. Yang wants to use the variable-cycle engine on the J-20B first. Now that the airport on Treasure Island has basically been completed, all kinds of fighter jets will definitely be deployed there in the future."

"If the J-20B can form combat effectiveness in advance, many things we want to do will be much easier."

"Well, I think it's okay."

Chen Nian nodded and replied.

After the last incident subsided, the overseas neighbors have not come out to make troubles for a long time.

But it is very important for us to be prepared and maintain a basic military presence.

And the best way of military existence is warships and fighter jets.

"But speaking of it, it seems that the United States has also suspended their Pacific Rim strategy?"

"Didn't you say that you would deploy medium-range missiles in the south? Now there is no news?"

"No news."

Chen Guo shook her head and replied.

"It's not just the medium-range missile program—it's their missile wall program. Judging from the current situation, it has been put on hold. Even the THAAD deployment on the island country has also been cancelled."

"Moreover, they did not withdraw from these two projects on their own initiative, but were rejected by local officials."

"This situation is very beneficial to us. It can be said that their influence has passively declined for the first time."

"It seems that our previous actions were indeed successful."

"According to this trend, as long as the Deep Blue 16 project is completed and the No. 01 aircraft carrier is launched, the entire first and second island chains will be under control, at least they will be evenly matched."

"very nice."

Chen Nian let out a long breath of relief.

The replay of this pass made him feel as if he had passed away.

Three full years have passed.

Three years ago, the country was in a climate of fear and anxiety.

A Middle Eastern power whose military strength is almost the same as ours has been hanged up and beaten. Everyone is asking, will we be next?

But now, this problem has quietly disappeared without a trace.

There is only one question that everyone is thinking about:

How many more years will it take before we can really compete with them?

For now, there is no answer.

After all, right now we're just trying to fill in what's missing and plug the most urgent holes.

It will take time to become a leader.

But Chen Nian believed that there would be one soon.

After leaving Chen Guo's office, Chen Nian went to Wang Jiancheng's laboratory according to the previously planned plan.

At this time, Qiao Mai had officially joined his gang and began to help him with the integration of electromechanical and hydraulic transformation of the exoskeleton.

I went there by myself, just to see how they are progressing and whether they need any extra help.

On the way, Chen Nian turned on the system and began to examine his current source situation.

Due to the previous "drainage" promotion of the Beijing-Shijiazhuang Railway, the number of his source points has increased far beyond expectations. So far, he has accumulated 24 points of source points, and the average daily increase of source points has reached a peak of 0.5.

In recent days, though, the number of origin growths has dropped significantly.

Obviously, it is because the technological fission potential of the category of "heavy machinery" is about to be squeezed out.

In the next step, Li Xiang should communicate with them and output more popular science programs, thus triggering a new fission.

What should I do?

J-22 seems to be a very good direction.

Or, gas turbines?

Anyway, let them worry about it

In a few minutes, Chen Nian had arrived at the door of the laboratory, and before he entered the open door, he heard the discussion between Wang Jiancheng and Qiao Mai inside.

".This motor is not working at all. The reaction speed is too slow. Coupled with the delay of the hydraulic system, the operation will have a serious sense of frustration."

"This thing is really upper body, let alone running, it's hard to even walk."

"The delay should be controlled within at least 300 milliseconds. If it exceeds this number, the agility cannot be guaranteed."

It was Wang Jiancheng who spoke, and he seemed very dissatisfied with the results at this stage.

"That can't be helped. The limit response speed of the current motor has to reach 500 milliseconds. To meet your standard, at least you have to wait for the next generation of DC servo motors to appear."

Qiao Mai replied with some helplessness.

"But doesn't it mean that the response speed of the motor is within 10 milliseconds? The fast one can even reach 0.1 milliseconds."

".You are talking about the start-up response speed! Is 0.1 milliseconds enough to reach the operating speed? We can do 500 milliseconds now, which is very good."

"If it doesn't work, don't pursue agility. Let's solve the problem of carrying weight first."

"Then my intention of designing this set of exoskeletons is against my intention!"

"How can there be any device that can fully achieve the design goal from the beginning? It has to be iterated from generation to generation."

The two people inside were still arguing endlessly, Chen Nian pushed aside the dustproof curtain and walked in, interjecting and asking:

"What are you two arguing about?"

Hearing Chen Nian's words, the two turned their heads subconsciously. After seeing Chen Nian's face clearly, Wang Jiancheng said quickly:

"Senior, you came just in time."

"We have encountered a problem now. The DC servo motor can't achieve the expected effect at all. The response of the exoskeleton is very slow. It's just a step and a fall when you put it on."

Chen Nian glanced at Wang Jiancheng, then at Qiao Mai, the latter's face was full of resentment.

It looks like the elder sister at home kindly helped the younger brother with homework, but was rejected in the end.

This made Chen Nian couldn't help but want to laugh, he shook his head lightly, and said:

"I also heard you arguing just now."

"Actually, what Qiao Mai said is right - haven't I already said it before? If you want to truly achieve the agility of a mechanical exoskeleton, the only way you can do it is to realize the BCI brain-computer direct connection."

"With the current technical conditions, even if the problem of the DC servo motor is solved, it is impossible to truly make the exoskeleton 'like an arm'."

"You might as well change your mind. Just do what your sister Qiao Mai said, first solve the problem of carrying weight, and then consider agility."

"But even if the problem of carrying weight is solved, it's useless! When an army fights, they don't have agility. Will the enemy wait for you to move up slowly?"

Hearing Wang Jiancheng's words, Chen Nian couldn't help but roll his eyes.

"You know an army of hammers!"

"You don't really think that the mechanical exoskeleton was built to train super soldiers like the Master Chief?"

"Don't be kidding. The real way out of the mechanical exoskeleton is to solve the problem of evacuation operations."

"What is evacuation warfare?"

Wang Jiancheng asked in a daze.

".The so-called evacuated operations refer to the dismantling of large-scale group operations into multi-module, decentralized, and complex operations beyond visual range, and the formation of the entire operation and command system through independent combat units."

"This way of fighting is actually a continuation of the modernized operations of the Air Force and Navy."

"Its purpose is to avoid the natural disadvantages of traditional combat methods and maximize the combat effectiveness of a single combat unit."

"Let's put it this way, it is a macroscopic three-three system"

"Oh, I see."

Wang Jiancheng nodded, but then asked again:

"But what does that have to do with the design of my exoskeleton?"

"It's a big deal."

"Such a combat method requires each combat unit to have extremely high firepower projection capabilities, otherwise, once the combat units are dispersed, they will be easily surrounded and wiped out."

"In order to achieve this goal, we must either engage in the miniaturization of weapons, or engage in human-machine cooperation in unmanned systems, or increase the load capacity—that is, the current mechanical exoskeleton."

"So, the significance of the mechanical exoskeleton does not lie in agile combat."

"Because on most battlefields, there are no scenes that require soldiers to maneuver frequently and move at high speed."

"What they need to do is to squat in a trench for a day, walk hundreds of miles on a long marching route, or guard behind a cannon to carry ammunition, and move hundreds or even thousands of rounds."

"In this case, how agile do you think they really need to be?"

"After all, we are not training Master Chiefs, but general fighters who can work closely together."

Hearing Chen Nian's words, Wang Jiancheng fell silent for a while.

On the other hand, Qiao Mai had a "yes, yes, that's it" expression all over his face.

Taking advantage of Wang Jiancheng's lack of answer, she opened her mouth and said:

"My thinking is the same. Solving the load problem can improve the continuous combat capability. As for further application, we can take our time."

"It's not to say that agile exoskeletons are completely useless, such as special operations, civilian mechanical control, etc., are still useful."

"But products always have to be iterated step by step."

"Just like our J-22 and J-20B, although they are so perfect now, behind the scenes, they must have been improved version after version. If you don't believe me, ask your senior, didn't he also participate in the process? Part of the job."

"That's right, Chen Nian?"

Hearing her question, Chen Nian was stunned for a moment.

Version after version improved?

really not

However, in the current situation, it is definitely not convenient to say such a thing.

So, he had no choice but to say:

"Well, yes, it does need to be changed many times."
