Open an aircraft carrier to fight against Japan

Lin Yuan thought to himself: "How mysterious is the source of this technology, how could I not know?" So Lin Yuan asked: "Where does it come from?"

Li Kai said with a smile: "You should know the original purpose of ground penetrating radar: one is to detect military facilities such as underground tunnels; the other is interstellar detection, using radar to detect the surface of unknown planets."

Lin Yuan smiled and said, "Why does it sound like a science fiction novel?"

Li Kai said with a smile: "Real technology is often more exciting than science fiction. The ground-penetrating radar technology we use comes from the Mars Project."

Lin Yuan thought to himself: "The Mars Project? I haven't even heard of it. Li Kai is just a captain and company commander. How did he hear about it?" So Lin Yuan asked, "How did you hear about this?"

Li Kai showed shame, and said: "Last time the General Armament Department sent an expert group to guide us in using this type of radar. There was a young engineer in the expert group who also liked to play games. We had a good time playing games, so he took all these things into his head. My son told me that the Mars project is a huge plan, and the short-term goal is to land on Mars."

"Because there is an atmosphere outside Mars, and there are often sandstorms on Mars, optical detection methods are greatly limited. Radar detection must be used to find a landing site for the Mars landing vehicle, and to detect the poles to determine whether there is ice on Mars. cover exists."

"Think about it, Mars is [-] million kilometers away from the earth. If you want to fly that far, the weight of the radar system on it must be very low, so the transmitter of this type of radar adopts the most advanced technology. Although it is small in size, it can The transmission power is very large, which is the technical source of our type of radar."

Li Kai was still not satisfied, and said: "The long-term goal of our country is to establish a Mars base, and even use more advanced technology to change the nature of the atmosphere of Mars and turn it into a second Earth."

Lin Yuan nodded and said, "Very good, what you mean, is our radar enough to detect underground oil resources?"

Li Kai said: "Of course, due to the different dielectric constants of different substances, the reflection and refraction effects on electromagnetic waves are also different. Based on this, we can know where there is oil, but oil is hidden about 1000 meters underground, so The detection accuracy may not be too high."

Lin Yuan said, "How accurate can it be?"

Li Kai replied: "It is impossible to know the situation of an area 30 meters by 30 meters underground, no matter how accurate it is."

Lin Yuan said: "That's enough, you should first investigate the oil reserves in the lower reaches of the Liaohe River, and leave the rest to me."

In the next few days, the Beijing ship dispatched planes and used ground-penetrating radar to survey and map the lower reaches of the Liaohe River. An oil field does not produce oil wherever it is drilled. Oil is a fluid, and it will flow underground. Therefore, it will accumulate under certain special terrain conditions, and the ground penetrating radar is to locate these places.

Lin Yuan then returned to the industrial area, intending to organize personnel and equipment for oil extraction. The drilling technology in ancient China was relatively advanced. Around 18 years ago, the drilling depth could reach 1000 meters. However, these technologies used animal power as energy, so the drilling speed It was very slow, and it took half a year to drill a 1000-meter deep well, which was obviously unacceptable to Lin Yuan.

Lin Yuan then thought of designing the drilling technology with his own strength, but he did not have experts in the field of oil exploration. Although the Beijing ship had some technical data, it did not have drawings and process instructions. Even if there were these things, they were not enough. For the mechanical field, if you have no relevant experience, even if you are given a full set of drawings and craftsmanship, the things you produce will still not reach the original level.

Lin Yuan flipped through the documents in his hand and drew up a list of experts.

When the experts were invited to the industrial area by Lin Yuan, they were still at a loss, thinking: "My profession is far from oil exploration, why did I invite myself here?"

The first question was missile expert Gao Ninghai. He asked, "Is there any relationship between missiles and oil extraction?"

Materials expert Su Zhengming also asked: "My professional direction focuses on non-metallic materials, but aren't all metal materials used in oil extraction?"

Zhou Huaxin, an expert in aerodynamics, said to Su Zhengming: "The dialectical point of view tells us that everything in the world is interconnected. Maybe your discipline does have some connection with oil exploration."

Su Zhengming smiled and said, "Old Zhou, don't just talk about these big principles, let me ask you, what is the connection between your major and oil exploration?"

Lin Yuan interrupted everyone's discussion, and said with a smile: "Please don't worry, I will answer these questions slowly for you."

Lin Yuan turned on the projector, and a huge stratum profile was displayed on the wall. Lin Yuan pointed to the black field at the bottom and said: "These blacks represent the location of the oil, and on it are all kinds of rocks. What we need to do is to penetrate these rocks from the ground and let the oil come out of the ground."

Su Zhengming asked: "When we drill into the oil layer, is the pressure in the oil layer here enough to push the oil out of the ground?"

Lin Yuan said: "We need to analyze this after we have drilled the well, but according to historical data, the pressure of the formation where the oil is located is enough to press the oil from about 1000 meters underground to the surface. of the wells will be self-flowing wells, which do not require complex pressurized oil extraction techniques."

Everyone looked happy. If it was a self-flowing well, the technical difficulty would be much less difficult. Lin Yuan first looked at the missile expert Gao Ninghai and said, "Old Gao, if I remember correctly, you once presided over the J-25 ground drilling Missile research?"

Gao Ninghai said: "Yes, that was a year ago, when we were equipped with aircraft carriers, we had the ability to strike against the United States, Japan and other countries. In order to attack the opponent's underground hangars, underground command posts and other institutions, the Air Force The Equipment Research Institute organized us to conduct research on ground-penetrating missiles and achieved good results, and now this type of missile has been equipped on the Beijing ship."

When Gao Ninghai said this, his complexion changed, and he said, "You don't mean to use ground-penetrating missiles to blow up the ground?"

Lin Yuan was noncommittal and said, "Tell us about this type of ground-penetrating missile."

Gao Ninghai said: "Although the name of the ground-penetrating missile sounds novel, it can be classified into the existing missile category. It is a missile with a tandem warhead. Everyone is familiar with the tandem warhead. For example, a while ago The Red Arrow 10k we used to hit Japanese warships used the tandem warhead.”

"Many of the targets that other missiles deal with are armored, such as tanks, warships, etc., so the primary warhead generally adopts the method of metal jet armor penetration, while the ground-penetrating missile deals with concrete fortifications, so the primary warhead uses Therefore, the missile adopts some special designs. For example, the warhead is made of high-strength materials, so the missile can penetrate into the concrete. In order to prevent the explosive from exploding in advance during the collision process, an additional inert material."

Lin Yuan asked: "Then can this kind of missile blow up the ground?"

Gao Ninghai thought for a while and said, "I also need to think about this. After all, the depth is 1000 meters. The enemy's underground tunnels are not that deep."

Lin Yuan said: "Actually, what I need you to do is much simpler than this."
