A few days ago, on June 17, 2022, the 003 aircraft carrier that the majority of netizens had been waiting for was finally launched. It really made everyone excited for a while, and the name "Fujian Ship" also aroused heated discussion. However, some military fans are still a little disappointed. Why is it not nuclear powered? In fact, there is no need to rush this, just take it step by step and you will have bread.
003 aircraft carrier is world-class in all aspects except that it is not nuclear powered. The most advanced one is the electromagnetic catapult device, which is firmly 10 years ahead of the United States. Although the USS Ford aircraft carrier in the United States also uses electromagnetic ejection , it is in a hurry to board the ship. The technology is immature and malfunctions occur frequently. It has not yet developed combat effectiveness. China's 003 aircraft carrier electromagnetic ejection technology is overtaking in a curve. The major contributors behind it are Rear Admiral Ma Weiming, academician of the Academy of Engineering, and his team.
As early as 2017, Academician Ma Weiming said that the ship-related technologies he studies have surpassed those of the United States.
Ma Weiming is a native of Zhenjiang, Jiangsu Province, born in 1960. At first, he had no intention of going to a military school, but when he took the college entrance examination in 1978, the army was recruiting students, and Ma Weiming was admitted to the Naval Engineering University by accident.
After graduation, Ma Weiming stayed at the school to teach while preparing for the postgraduate entrance examination. At that time, an old professor, Zhang Gaifan, had a keen eye and thought that Ma Weiming was a good candidate. Professor Zhang is engaged in research on motor theory and ship power systems, and has made great achievements. He also has in-depth research on the " electromagnetic gun ". So Ma Weiming devoted himself to Professor Zhang’s research direction.
Later, Ma Weiming entered Tsinghua University for further studies and obtained a doctorate in electrical engineering. Tsinghua University is full of talents, but the leading talent in the field of electrical machinery is none other than Ma Weiming. He became a professor at the age of 34, was promoted to doctoral supervisor at the age of 38, and became the youngest academician of the Chinese Academy of Engineering at the age of 41.
html In the late 1900s, a large generator system imported by China from a certain country suffered a serious failure. Ma Weiming sent a professor and technicians from relevant departments to the site to repair the failure. Everyone quickly discovered the problem. There were design flaws in the headgear end of the device, and the production quality was substandard.
Since the equipment was imported, it required communication with a certain country. After hearing about it, Ma Weiming asked for sufficient evidence of the failure. Subsequently, an expert group of 10 people came from a certain country, 8 of whom had the title of chief designer or chief engineer, and their attitude was very arrogant. As soon as they arrived at the scene, they said that there was no problem with the power generation system and that the failure was caused by improper operation by Chinese personnel.
Ma Weiming had no choice but to ask the other party to take out the equipment structural design drawings and analyze the reasons together. In order to confirm the cause of the failure, a Chinese professor copied some data from the drawings. Seeing this, the foreign experts quickly folded up the drawings and said in a mocking tone: "You have learned a lot today!"
Ma Wei was prepared for tomorrow morning and took out a very large drawing and said to the foreign experts: "This is the structural diagram I drew. Please compare it and see where the differences are." This is the drawing that Ma Weiming specially asked a staff member of the research team to draw. The foreign experts looked at it carefully and were all shocked. This picture Exactly like their original blueprints.
But even though they were surprised, they still refused to admit that there was a problem with their machine. Ma Weiming pointed to the drawings and explained them one by one. In the end, foreign experts couldn't refute it and started to make nonsense, saying that we don't understand your theory. Ma Weiming couldn't bear it anymore and said angrily: "It doesn't matter if you don't understand, I'll teach you for free!" This completely stunned the foreign experts.
Since then, Ma Weiming’s research results have been continuously reported, and only some people abroad are jealous. His contribution is not just electromagnetic catapult technology. As early as 2001, Ma Weiming developed the world's first AC and DC dual-winding generator system, which greatly improved the submarine power supply system; in 2010, Ma Weiming developed the shipboard medium voltage The DC transmission system is also the first in the world. The electromagnetic ejection of the 003 aircraft carrier uses medium voltage DC technology.
In 2017, when the majority of military fans were rejoicing for the Type 055 large drive and the Type 002 aircraft carrier, another exciting news was broadcast on TV, which can be called the third good news for the Navy along with the former, that is, the aircraft developed by Ma Weiming's team The shaftless pump technology used in the nuclear submarine is another world leader.
Foreign submarine power technology, including the United States, still uses the traditional method of pump-jet propulsion driven by a mechanical drive shaft, which has the problem of coupled vibration, high noise, and takes up a lot of space. The shaftless pump is all-electric and does not require mechanical transmission components, which can minimize the noise of the submarine and save more space.
Specifically, shaftless pumping can reduce submarine noise by one tenth. It may not sound like much, but in fact, the noise reduction of submarines in various countries has been as extreme as possible. For example, relevant data shows that the noise of US nuclear submarines is about 95 decibels, and that of Russia is slightly higher, about 110 decibels. The noise level of Chinese submarine was originally between the two. After using the shaftless pump system, the noise is lower than that of the United States.
submarine is extremely sensitive to weight distribution. The shaftless pump can save space and reduce weight. Therefore, it is a world-leading innovation in every aspect, and it is the only one in the world. There is no other submarine. China's next generation submarine using shaftless pump push will become a real " ocean black hole ". Netizens speculate that 095 will be used. It would be false to say that foreign countries are not envious.
When Ma Weiming was interviewed that year, he said a very encouraging word, "If you want to lead, lead the United States!"
Such a top scientist, the country naturally attaches great importance to. Ma Weiming has won numerous awards, and was awarded the "August 1st Medal" in 2017. Once, when Admiral Wu Shengli, then Commander of the Navy, and his party went to the Naval Engineering University to participate in an event, it happened to rain, so a photo captured by the media went viral. Ma Weiming was seen holding a walkie-talkie while Admiral Wu Shengli was standing. Hold an umbrella for him from behind.
Ma Weiming is known as the "Father of China's Electromagnetic Ejection". At that time, Americans evaluated Qian Xuesen, saying that he alone could equal 5 divisions. Now the American media evaluates Academician Ma Weiming and says that he alone can equal 10 divisions!
The world is such a wonderful place. Although many international students in our country are unwilling to return to China, at critical moments, we always have better talents.
