Treasure Island was completed and the airport construction plan was put on the agenda. Chen Nian, who was far away in China, finally breathed a sigh of relief.
Things at sea finally calmed down completely. After that, there should be no more waves for a long time.
the reason is simple.
The combination of J-20B + island building is really too powerful.
The Sky Whale was born nearly 10 years ahead of schedule, and its performance has almost doubled, which means that today, when the United States is deeply mired in the war on terrorism and is temporarily unable to touch the South China Sea, we have more time and more abundant resources. space to operate at sea.
The cost of building islands has been greatly reduced. In a very short period of time, we can build one "leapfrog" island after another in the Xisha Sea.
Of course, no matter how abundant the funds are, it is impossible for each of these islands to be built into a large island with an airport, various infrastructures, and even living areas like Yongxia Island in later generations.
The most likely possibility is that these islands have the ability to take off and land helicopters, and some islands have ports that can berth small ships and have basic self-sustaining capabilities.
Originally, according to this design, the deterrent capabilities of these islands were actually insufficient.
But the problem is that everything changed when J-20B began to be deployed to Xisha.
The scope of the Air Force's activities has expanded from an island to a group of islands.
The enemy's attack methods have also been greatly weakened in effectiveness.
Yes, if there is only one Yongxia Island, you can easily destroy it with a saturation attack. After this nail is pulled out, our control over the South China Sea will decline.
But now we have not only Yongxia Island, not only Treasure Island, but also a series of small islands.
What, do you want to blow them up one by one?
As long as we can't blow up all the bombs in the first wave of attacks, our air superiority will not be completely lost.
Because our J-20B can take off from any island in an emergency!
This is the difference between an aircraft carrier and an "aircraft carrier system".
Otherwise, why would the United States engage in a dual aircraft carrier battle group every time it takes serious action?
Quantity, at some point, will also become the key to solving problems.
quantity quality
Chen Nian suddenly thought that the J-20B deployed to Treasure Island was not complete yet, and its range was still too short.
However, once the variable cycle engine from the 611 Institute is released, its combat effectiveness will be qualitatively improved.
A combat radius of nearly 1,000 kilometers covers almost the entire Southeast Asian peninsula.
At that time, under the most extreme circumstances, it is not impossible to defeat India.
Thinking of this, he smiled with satisfaction.
In fact, he had already made this plan when he first imagined the STOVL fighter jet.
Now, nearly two years have passed, and this goal has finally been achieved.
Taken together, this set of technological advancements has also brought him considerable rewards.
Now, his average daily growth in the number of source points has exceeded the 0.3 mark for the first time, maintaining this number for a week in a row.
Although there will definitely be fluctuations in the future, this can be regarded as a huge improvement.
The total number of source points he held in his hand also reached an astonishing 16 points.
It's time to start planning the next step.
He needed a large-scale project that could be modularized to consume these source points.
Chen Nian frowned and glanced at the schedule.
Tomorrow is the regular working meeting of the Spark team, and we can take this opportunity to learn about the progress of each project.
Including the ongoing Deep Blue 16 project, including the Rainbow-8 UAV project, including the H-20 project that has cooperated with Russia to start pre-research, and also includes the high-speed rail project that has completed the construction of the first train set and is ready to start testing.
During this period of time, I actually invested a lot in these projects, but the investment was basically scattered.
This shows that these projects have indeed not encountered critical technical problems, and there is no need to take action on their own for the time being.
In other words, maybe some problems have been encountered, but the project leaders believe that the cost-effectiveness of involving themselves is too low.
If this is the case, then you need to analyze it carefully again.
According to the prompts of the "Task Manager", you may be able to invest more resources in certain key points to speed up the progress of technology development.
Chen Nian put away his wandering thoughts and looked back at the time.
It's time to go out for some fun again.
By this time, NPU had gone on summer vacation and most of the students had gone home, but the cafeteria was still open.
The reason is simple. In this already extremely stressful school, there will always be some top students like Chen Nianla, Wang Jianchengla, and Qiu Maila who stay in the school.
However, today happened to be the time that Chen Nian and the other three people had made an appointment to have dinner together, so he did not go to the canteen, but went directly to the hot pot restaurant outside the west gate.
In the hot pot restaurant, Chen Nian saw the other three people who had already ordered and waited for a long time.
"I'm just waiting for you. Why are you so late today?"
Qiu Mai asked as he handed the chopsticks to Chen Nian.
"I'm sorry, something has delayed me."
Chen Nian didn't say anything clearly, and Qiu Mai didn't continue to ask.
In this regard, she is actually not stupid.
Even if she hadn't joined Spark like Li Xiang, she could still guess that Chen Nian should have some confidential projects that were inconvenient to disclose to the outside world.
This is not surprising, she has such a project herself.
It's just that the scale is relatively small, and the role I play in it is relatively marginal.
After exchanging greetings, several people started cooking hot pot enthusiastically, each chatting about their recent affairs.
Li Xiang and Chen Nian know each other well and cover well.
Wang Jiancheng is tinkering with his exoskeleton. Now that he has more funds, he is more playful. He even begins to think about whether to get a large-capacity battery first.
Qiu Mai, on the other hand, is relatively ordinary. He attends classes, works on projects, and prepares to review for the postgraduate entrance examination.
It can be regarded as the basic path of an "ordinary academic master".
After chatting for a long time, the pot was hot and the dishes were cooked, but few of them were in a hurry to move their chopsticks.
Not because they were too absorbed in chatting, but because everyone was attracted by a piece of breaking news on TV.
"On August 19, a major engineering accident occurred somewhere in Hubei. An auxiliary tunnel in a certain railway section collapsed during construction, causing 11 people to be trapped. They have not yet been rescued."
"Fortunately, the tunnel ventilation duct was not blocked and the 12 trapped workers were able to obtain the oxygen necessary for life. The 12 trapped workers were safe and sound."
"Currently, rescue work is being actively carried out."
Looking at the reports on the news, the four people's expressions became solemn.
"Shiyan. The geological conditions there are not bad. Tunnel collapse? Is this an engineering design problem?"
Wang Jiancheng asked doubtfully.
"Not necessarily. It may be an engineering design problem or it may be force majeure."
"In general, the Hubei area is not as complex and dangerous as the karst landforms in the south, but the groundwater system is rich and the rock formations are seriously eroded, so construction is still very difficult."
"In addition, our current construction equipment is relatively backward, so problems are normal."
"--I can't say it's normal. In short, the possibility is not low."
After Qiu Mai finished speaking, he continued to sigh:
"In the past two years, we have indeed made quite a breakthrough in the military industry, but in the civilian field, especially in the field of large civilian machinery, it is really not enough."
"Look, we are building high-speed rail now, but in fact, what will happen even if the high-speed rail is built?"
"It's impossible to have a train but no road. No matter how fast the EMU is, it still has to run on the railway."
"The terrain of our country is so complex. If we want high-speed rail to cover the places where it is needed to the greatest extent, we have to build bridges and build roads."
"Bridge erecting machines and shield tunneling machines are areas in which we are extremely lagging behind."
"Extremely backward?!"
Chen Nian was shocked.
In his mind, these two gadgets are typical cases of reverse export of domestic heavy machinery. Not to mention domestically, even in the era when he came back, the TBMs were so powerful that Western manufacturers were completely out of business. .
With such strength, there are still times when he is "extremely lagging behind"?
Seeing Chen Nian's unbelievable expression, Qiu Mai nodded slightly and replied:
"Yes, otherwise what do you think?"
"I am originally engaged in machinery, and I am more concerned about this area. The last report I saw showed that more than 80% of domestic shield machines now rely on imports."
"Moreover, according to market forecasts, this number will continue to rise in the next few years, and may reach a peak in 2009, which is more than 98%."
"If that's the case, it will be really difficult for us to make a comeback."
Good guy, 98%
In essence, the entire country's TBM market is controlled by others.
Chen Nian couldn't help but frowned.
Based on historical experience, he knew that this situation was temporary.
Just like the dilemma of rare earths being controlled by the West, it is also temporary. The upper levels always have various ways to mobilize various resources to fight a turnaround in these key areas.
But it is undeniable that this is a "turnover" after all.
Turning over means that we have indeed been suppressed, and we have indeed lost significant benefits because of the other party's suppression.
If such a loss could be saved, how much would it be?
Chen Nian asked:
"Approximately how large is our current shield machine usage scale?"
Qiu Mai shook his head and replied:
"We don't know the scale of use, but according to predictions, by next year, we will have demand for at least 200 units."
"If we still consider the high-speed rail project, it is estimated that even 300 units will not be available."
"At the current average import price, a shield machine costs at least 100 million yuan. Calculated in this way, the annual sales volume is about 30 billion yuan."
30000000000!
This does not seem to be a big number, but Chen Nian knows that this number is a conservative guess based on the existing situation.
After all, neither Qiu Mai nor those economists could predict the true development speed of China in the future.
By around 2008, due to the knock-on effects of the Olympic Games and other factors, a large number of developed cities began to build subways, and high-speed railways were fully rolled out. Coupled with the development of certain highways and undersea tunnel projects, the demand for this thing could be Definitely not just 300 units.
He remembered a data. In 2020, the domestic demand for TBMs was 650 units.
Moreover, this number has declined.
In fact, the demand for TBMs has remained high since 2011. In 10 years, the internal output alone should be above 5,000.
"That's a lot of money."
Chen Nian couldn't help but sigh.
"Yeah, this thing costs money. Hey, it's built. Don't you want to build a mechanical exoskeleton? This shield machine is a large mechanical exoskeleton. How about you just get rid of it?"
Wang Jiancheng rolled his eyes and replied:
"It's not the same thing at all, okay?"
"If we really want to build a shield machine, we might as well let the guys from the Sky Whale do it."
"The design of the cutter suction knife unit of the Sky Whale is actually closely related to the shield machine. I guess there won't be a big generation gap in technology."
"In addition, wasn't it previously advertised that the Sky Whale uses the ship's integrated power system? It's the same thing if it's directly transplanted to the shield machine."
Hearing this, Chen Nian's eyes lit up.
yes!
The design of the Sky Whale is really similar to the design of the large shield machine.
No, it shouldn’t be said that they are similar. It should be said that the basic technologies they involve are actually interoperable.
In this case, if you want to build a shield machine, it shouldn't be too difficult, right?
Thinking of this, he immediately clicked on the system page in his mind.
Then, he entered an analytical entry into the system.
"Zhenxing super large shield machine."
The results were quickly fed back from the system.
[Zhenxing Super Large Shield Machine]
[Analysis requirements: 4 source points]
really!
Chen Nian's spirit was greatly boosted.
This thing is really cheap.
The 4 source points, compared to the 16 source points I have on hand, are really nothing but water——
However, Chen Nian would certainly not be so impulsive and analyze it immediately.
He must be responsible for the entire Spark team and the entire country.
The regular meeting of the Spark Team is tomorrow. At tomorrow's meeting, he can put forward his own suggestions and let other more professional people judge whether it is feasible.
Thinking of this, he picked up the chopsticks again and put a piece of mutton into his bowl.
Others also came to their senses one after another, and moved their eyes from the TV to the pot.
"I hope everyone is okay."
Li Xiang sighed and said.
"It'll be fine for sure."
Chen Nian answered without thinking.
He just remembered that this accident was actually quite famous in his time.
This was a highly successful rescue under extreme conditions, and it can be regarded as a rare advanced case among mine and tunnel rescue cases in the world.
Based on the experience of this rescue, we have actually done better than other countries in many subsequent accidents.
However, even so, Chen Nian still has an expectation in his heart:
I hope that such an accident will never happen again in the future.
