Open an aircraft carrier to fight against Japan

Looking at the large green area in the outer northeast of the map, Lin Yuan couldn't help but think of Chekov's famous saying: "I have no choice but to describe such a beautiful scenery as the banks of the Amur River. It can show submission.” The Amur River is Heilongjiang.

This area is extremely rich in resources. First of all, forest resources. The entire 960 million square kilometers of China only has 100 million square meters of forests, while the northeast region of 100 million square kilometers has 70 square meters of forests; secondly, mineral resources. A large amount of iron ore, coal mines and other mineral deposits necessary for the metallurgical industry, and a large amount of oil and natural gas resources in the waters near Sakhalin Island. Although coal is still the main fuel in this era, oil will soon catch up; Then there is the agricultural resources. The Chinese have all heard the story of the Great Northern Wilderness becoming the Great Northern Cang. The Outer Northeast has the most fertile black soil belt on the earth. It is described by a Jewish saying: "This is a land flowing with milk and honey. .”

Finally, and most importantly: gold!Since Russia began to mine gold in the outer northeast region, the annual output has exceeded 00 tons, while China's annual output in 1995 was only a poor 500 tons.

The role of gold in international trade is self-evident. With gold, you can buy goods all over the world. With gold, you can use the gold standard system to issue currency. The so-called gold standard system refers to the currency issuance linked to the gold storage. , such a currency can be used as a settlement currency in world trade. When this currency has been used all over the world and it is difficult to replace it, the gold standard system can be abolished. The wealth of the world is in your pocket!

Lin Yuan stood up and paced around the room.In the 21st century, this is what the Americans did. They used advanced science and technology to send the US dollar to the status of the world currency. Blood and sweat became their source of pleasure!

"We also want to put our currency on the status of the world currency! Only by occupying the commanding heights of finance can our nation remain invincible forever!" Thinking of this, Lin Yuan couldn't help feeling excited, but he was not a student He didn't think clearly about many of the joints involved in the background of the economy. Even so, he also knew how arduous and long the process would be.

But the predicament in front of him is like a big basin of cold water, pouring heavily on his heart. With the current strength of the Beijing ship, it is far from enough to capture the outer northeast region. It is indeed difficult to develop his own industry.

At this time, Lin Yuan looked at the time, and it was almost ten o'clock, and he would invite the scientists and engineers on board to participate in the symposium.

As I said before, the Beijing ship is going to sea this time to perform test missions, so there are many scientists and engineers on board. There are more than a dozen academicians from the Chinese Academy of Sciences and the Chinese Academy of Engineering. It is the mainstay of Beijing Ship's future industrial development.

At the beginning of the meeting, Lin Yuan said: "Experts and professors, hello everyone, now is the time for everyone to show their talents. Let me first talk about our current predicament."

Then Lin Yuan turned on the projector and began to speak with the help of slides: "We are currently in the 19th century, and the industrial level of this era, I believe you understand better than me. Before our Beijing ship passed through, it had just carried out an internal maintenance of the base. Due to the relatively high level of design and manufacturing of our aircraft carrier, the time interval between the two base internal maintenance is also relatively long, reaching 40 months. For other crew-level maintenance and intermediate-level maintenance, since our aircraft carrier has its own maintenance Most of the small and medium-sized faults in the workshop and maintenance equipment can be dealt with, so the daily maintenance of the aircraft carrier is not a big problem."

Lin Yuan looked at them and continued: "Our real dilemma is that we cannot replenish a lot of equipment. Take our carrier-based aircraft as an example. Everyone knows that carrier-based aircraft is the core of an aircraft carrier's combat effectiveness. Carrier-based aircraft need The fuel and lubricating oil can’t be refined in this era, and missiles, bombs, and machine shells can’t be replenished. Fortunately, the most difficult thing to overcome is the replacement of aero engines.”

"Without an engine, an airplane cannot take off. The working conditions of an aeroengine are extremely harsh, and most components work in an environment of high temperature, high pressure, and high load. Our J-24 aircraft uses a turbofan 30 engine. This type of engine The temperature in front of the turbine has reached 2100K. Such a temperature will generate a lot of thermal stress in the turbine blades. Coupled with high gas force load and centrifugal force load, the blades are prone to cracks, and the crack growth speed is also very fast. "

"Everyone knows that after the turbine blades are processed and formed, you must never touch them with your hands, because the salt in the sweat on your hands will accelerate the corrosion of the blades. The salt in the sea is greater, so the life of the blades will be longer than that of road-based fighters. The blades used are short, so it is very likely that our aircraft will not be able to take off due to engine problems in the future."

At this time, a gray-haired old man said: "What's the use of saying this? Do you expect us to be able to manufacture turbine blades now? There are no doors! The first and second stages of the turbofan 30 are used for the rotor blades." What? Nickel-based alloy! With the support of special funds from the State Council, our research team has been working on this material for ten years. During this period, almost all universities, research institutes, and factories in the country have assisted us. You said that we have reached the present This place, where can I get this kind of material?"

Lin Yuan saw that the speaker was Su Zhengming, an academician of the Chinese Academy of Sciences, one of the oldest and most capable material science experts in China, and many middle-aged experts were his students, so he talked about The words are inevitably a little arrogant.

Lin Yuan knew very well that Su Zhengming was an extremely enthusiastic person, even if his words were a little harsh, he didn't care, and said: "Old Su is right, we really can't produce such materials now."

Su Zhengming added: "Now we can't produce not only this material, but also other materials. Let me give you another example of a bearing. I went to see the spectroscopic analysis of the lubricating oil attached to the high-pressure rotor. The iron element in it The content exceeds the standard by more than a dozen percentage points, indicating that the bearing has suffered a lot of wear and tear, what material is used for the bearing, iron-tin alloy, this material is much easier to make than nickel-based alloys, but can we make it?"

Lubricating oil spectral analysis is: since the lubricating oil has to flow through the bearing, if the bearing is excessively worn, the iron element in the bearing will enter the lubricating oil, and then perform spectral analysis on the lubricating oil to determine the content of iron in it , the wear degree of the bearing can be analyzed.

Lin Yuan said: "Of course, we can't produce these materials now. We can do it step by step. I think what we need to do now is to first determine the most basic things for industrial development."

Su Zhengming nodded and said: "You are right. I think the most basic thing is the measurement of the basic unit in our physics: for example, how far is a meter, how long is a second, There is an old saying: "Those who do not seek the world will not seek one domain." If these problems are not resolved, it will definitely bring troubles to the long-term development in the future."

Lin Yuan knows Su Zhengming's character, the more you work for him, the happier he is, because he thinks this is your trust in him, so Lin Yuan said: "Old Su, since you brought this matter up , then you will do your part, okay?"

Without even thinking about it, Su Zhengming said, "Don't worry, there's no problem."

Lin Yuan nodded and said: "The next question is the question of standardization. We all know that standardization is a key step in the success of modern industrial mass production. On this point, we have many national standards, which can be directly applied. , and some industry standards, because our current environment is different, in practice, we will analyze and improve step by step.”

Everyone present nodded, and Lin Yuan said: "Then let's discuss next, which specific industry should we develop first?"
