Speaking of nuclear submarines.
We may think of Huang Xuhua's anonymity for 30 years.
Suddenly, it was a hit.
But there is actually one more person
It's also very powerful
He used to say that he had only done two things in his life.
First, build nuclear submarines.
Second, build nuclear power plants.
On both of these things.
He was like a cattle.
He was the first chief designer of China's nuclear submarines. Nuclear power expert. Academician of the Chinese Academy of Engineering, Peng Shilu
Unfortunately. Peng Lao died in Beijing at noon on March 22 at the age of 96.
As the first chief designer, he is often referred to as the father of China's nuclear submarines, but Peng Lao resolutely disagreed with this statement before his death. He said our country's nuclear submarines work. Not one or two people can do it, it's the result of all of us working together, we have a group. The name is Nuclear Submarine Man.
The success of China's nuclear submarine research and development is the crystallization of group wisdom. There is no such thing as a 'father'. I was at best a screw on a nuclear submarine.
Peng Shilu began to take charge in February 1962, the demonstration of nuclear power equipment for submarines and the early development of major equipment, in that era, Peng Shilu and all the people engaged in nuclear submarines at that time did not know what nuclear submarines looked like, they only vaguely saw the general appearance of nuclear submarines in the newspapers, and from the model toys they bought.
The development of nuclear submarines is not enough to rely solely on enthusiasm. At that time, no one really grasped the knowledge of nuclear power, everyone learned from scratch, and our country wanted to build nuclear submarines by relying on two words and self-study.
At that time, most of the people in the seminar room were newly graduated college students, and they were not majoring in nuclear science, Peng Shilu and several other colleagues who stayed in the Soviet Union were teachers, and 5 professional courses such as reactors were opened, most of the people in the seminar room could only speak Russian, not English, and most of the foreign language materials were English, peng Shilu organized everyone to learn English. While looking at the professional information about nuclear submarines.
After two years of hard work, the whole team basically passed the English reading pass and understood the basic situation of foreign nuclear power plants and nuclear power equipment.
After the nuclear submarine project was officially launched. Because there is no experience. At that time, a lot of work was to cross the river by feeling the stones. Sometimes we have big differences over various issues. At this time, it is extremely important to have a master who can concentrate everyone's wisdom and opinions and make decisions.
In the nuclear submarine research and development project. Peng Shilu got the nickname Peng Bold, because he often dared to make decisions, he told researchers to do experiments to speak with data, and finally I was responsible for signing when I needed to sign, and when there was a result, I was responsible for all of us, and when there was a mistake, I was responsible.
When building nuclear submarines, there are many cases of Peng Shilu boldly making decisions, some people say that Peng Shilu dares to decide as long as he has 70% certainty, and the other three dangers are then tried to prevent it, and the courage to take risks is a prominent feature of his personality.
Non-knowledgeable people can't make a decision.
People who are not open-minded cannot make a decision.
He is also never blind to the clapping, and one of the things he often asks is where is the experimental data? You can't hide from me, I'm going to count it myself. He figured out his own slide rule and formula and started counting on the spot, because there was no computer at that time, and the whole team only had a hand-cranked calculator. A lot of data has to be pulled by a slide rule. The plan is calculated.
On August 30, 1970, the Chinese-made 1:1 nuclear submarine land form reactor was tested. Full power operation is achieved.
Just four months later. On December 26, 1970, China's first independently developed nuclear submarine was successfully launched.
Of particular note is that there are 46,000 parts on board, requiring as many as 1,300 kinds of materials, without a single foreign screw.
In addition to the field of nuclear submarines, Peng Shilu has also made indelible contributions in the field of nuclear power in China, nuclear power plants are strategic high-tech industries, which is a place where major powers must compete, and the development of nuclear power is an important way to maintain and develop nuclear forces in peacetime.
In the 1980s, the entire Daya Bay nuclear power plant was still a swamp, and Peng Shilu waded a lot of muddy waters in the initial exploration, which was equivalent to demining for the later projects and laying a good foundation for the subsequent development of Daya Bay.
He was also involved in the design and construction of two 600,000 kWh nuclear power units. Provide a scientific basis for the construction of nuclear power plants.
Affected by the Chernobyl nuclear power plant leak in 1986, millions of Hong Kong people signed and paraded the streets to oppose the construction of nuclear power plants.
Peng Shilu said that the atomic bomb contains more than 90 percent of uranium, such as alcohol.
Nuclear power plants contain about 3% uranium, such as beer.
Alcohol burns at the slightest point of fire, while beer is not combustible.
Before the launch of the land-based model reactor in 1970, he was urgently recalled from the test site by the Military Control Commission to answer people's questions about whether the nuclear reactor would explode if something happened.
From nuclear submarines to nuclear power plants, Peng Lao has paid a lifetime for the development of the republic's nuclear industry, and the new nuclear submarines of the Navy today are constantly being manufactured, these underwater dragons have consolidated the country's coastal defense, at the same time, more and more nuclear power plants will appear in the land of Shenzhou, and these clean energy sources continue to protect our green waters and green mountains.
From the smooth launch of the first submarine, the Long March 1, to the latest generation of 096 strategic nuclear submarines, the development of China's nuclear submarines has gone through three generations, and the 096 type is China's latest strategic nuclear submarine.
What is a strategic nuclear submarine? Let's briefly popularize the science.
Nuclear submarines are generally divided into two types, one is offensive nuclear submarines.
The main weapons are torpedoes, anti-submarine missiles and cruise missiles.
The second is a strategic nuclear submarine.
The main weapon is ballistic missiles, which we usually call nuclear weapons.
Submarines were put into battle in world war I, and due to their unique concealment, they could not rely on any air, lurked on the seabed for a long time, and became a huge threat to ships at sea.
It can launch an attack without you noticing, in the era of underdeveloped exploration technology, submarines have become a nightmare for warships at sea, many aircraft carriers are buried in their hands, and when people master nuclear power technology, the comprehensive performance of nuclear submarines is getting better and better. Therefore, powerful strategic nuclear submarines are the real heavy weapons of great powers.
Here, the hammer has to pay tribute from the heart, our older generation of scientists, without their efforts, there would be no we are today.
The 096 nuclear submarine is about 150 meters long, about 20 meters wide, the maximum diving depth can reach 600 meters, 200 meters more than the 094 nuclear submarine, its shell is made of high-strength composite diamond, and it is also equipped with new silenced tiles to minimize sound and noise. The volume of the Type 096 when sailing underwater does not exceed 100 decibels, almost silent underwater.
Like Russia's North Wind God class nuclear submarine, its volume is 108 decibels, the latest submarine in the United States also has 105 decibels, from the volume alone, China has become the world's first
To achieve such an outcome, it is necessary to mention another scientist. Professor Ma Weiming
Under the leadership of Academician Ma Weiming, China has successfully developed shaftless pump spray electromagnetic technology to maximize noise reduction, which is very important for submarines with high speed, but the most important thing is to have a small sound, thousands of miles away do not let the other party know your existence, otherwise how to kill people invisibly on the ocean.
Shaftless pump spraying gets rid of the drive shaft required by mechanical pump spray and propeller, so that the vibration and noise generated by the drive shaft are also lost. In this regard, we are ahead of the United States.
The only one in the United States that uses shaftless pump spray technology is the Virginia-class submarine, but it only plays an auxiliary role, perhaps as Academician Ma Weiming said, to lead the United States.
In terms of displacement and speed, the 096 type is not to be outdone, with a full displacement of about 16,000 tons and a maximum underwater speed of 35 knots.
Compared with the Type 094 submarine, the 096 nuclear submarine also has a prominent advantage, that is, it is possible to get rid of the design of the turtle's back. Turtleback, like the word, is the protruding part of the submarine, and its appearance is usually due to the excessive size of the ballistic missiles on the submarine.
At the time of the appearance of the Type 094, our country's pressure-resistant hull technology was not mature, so when huge ballistic missiles were loaded. There is also a part exposed.
In order to ensure the streamlined shape of the hull, reduce the resistance, and ensure the safety of the missile, only a turtleback fairing can be added outside. However, compared with the teardrop-shaped streamlined submarine, its resistance has increased, and the appearance is not very good. However, in recent years, our country has conquered the pressure-resistant hull technology, so the Type 096 nuclear submarine may not have a turtle back.
Secondly, the weapons and equipment of the Type 096 are also much more advanced, and it will be partnered with China's third-generation intercontinental submarine-launched ballistic missile JL-3, and can also carry dozens of pieces, with a range of 12,000 kilometers, which can hit any place in the world. Not only that, but this missile may carry more than 10 multi-warheads. The penetration performance of the missile has been greatly improved.
The missile is expected to become operational around 2026. And this is also just in line with the timeline of the 096 nuclear submarine in 2020, which can be predicted. If submarines can enter service around 2026, our country's strategic nuclear deterrent will be enhanced.
In the near future, our nuclear reactors may also be used on aircraft carriers. Help the Chinese Navy sail farther into the ocean.
All of this will make us remember that the older generation of scientists who supported the spine of the new China can be loyal to the motherland and dedicate themselves to the prosperity and strength of the motherland if they are alive.
That is a portrayal of Peng Lao's life.
And our descendants must do their best to protect their predecessors.
The prosperity of the construction.
