 Chinas chief designer of conventional submarines, we are far behind the world leader.


Hubei daily full media reporter Jiang Hui correspondent Wan Li Ge Mengmeng Afternoon sun, sprinkled the room. Wu Chongjians office, three submarine models with different shapes, tell us that this is a person who goes with the boat. From running to running and running to local areas, the conventional submarine designed by him presided over a strong underwater the Great Wall in the deep ocean of the motherland. The Hubei Daily reporter came close to the chief technical expert of the Chinese ship heavy industry, Wu Chongjian, the general designer of the conventional submarine, which opened the world of the submarine, seventh. Independent innovation, leading to the forefront of the world - Conventional submarines are unconventional Conventional submarines are not conventional. Our AIP conventional submarine has entered the worlds advanced ranks. Speaking of Chinas conventional submarines, Wu Chongjian is proud to say that his own children are competing. The submarine, known as the undersea ghost. It concealment itself, let the enemy guard against danger, and at any time give the enemy a fatal blow. At present, the biggest challenge of the sea is transparent ocean, which makes marine military equipment nowhere to hide. Conventional submarine has long underwater continuous navigation ability and excellent underwater acoustic stealth ability, and has become a weapon to crack transparent ocean. As a giant system engineering, submarines hold power, craft, vibration and noise reduction, cabin atmosphere, communication, navigation, radar and other innumerable equipment and millions of components. Leading the way, this proud word, in a poor and white era, did not dare to think. Wu Chongjian participated in the development of type three conventional submarines, and was the chief designer of the two submarines, witnessing and experiencing the great stride of Chinese submarines from weak to strong. The great development of submarines is inseparable from the rapid development of Chinas economy. looking back at history, he was filled with emotion. In the past 50 years, Chinas conventional submarines have gone to the forefront of the world and become the killer weapons to safeguard national marine rights and interests. What is the fast running of Chinese submarines from nothing to nothing? Always adhere to the theoretical innovation based on practice, let us go beyond! Wu Chongjian said, submarine technology is too secret, relying on the introduction of foreign technology can not get through, only self reliance, independent innovation. This competition on the tip of the knife is bound to take a thorny road for the development of conventional submarines. How hard is it to be creative? For example, he said, the weight of a seawater cooling pump in a submarine dropped from 100 tons to 18 tons, which took 15 years. This is not the longest, and some innovations even took 30 years. Innovation has brought about great changes: the improvement of a cooling pump not only saves valuable space for narrow submarines, but also reduces energy consumption from 13 kilowatts to 3 kilowatts. The three extreme deep submergence is proud - Scientific experiments cant take risks Bang! Bang! in the depths of the ocean, a terrible noise broke out in the conventional submarine compartment, which was the sound of steel rip under the pressure of sea water. Faced with the danger, the sailors were calm and committed to their posts. What is the bottom line of officers and men going to Longtan? Wu Chongjian, the deputy chief designer who participated in the deep diving experiment, was the one who gave them the reassurance. I participated in the deep diving test for the first time, the head of technology and the right to terminate the test at any time. A deep submergence, and the ultimate deep diving, many people are afraid. At that time, a new technology was applied to the submarine, and the participants were worried about danger. With the approaching of the deep diving days, the fear is increasing day by day. Anyone who has gone through the submarine knows that when the submarine is afraid of falling down, two is afraid of water. The sea pressure is huge. As long as the submarine shell has a hole of more than one centimeter in diameter, the whole submarine will be filled with water for a short time, and there is a risk of sinking. What should we do if the shell is cracked? Facing the one hundred thousand how to do, Wu Chongjian and the technical team are the science workers, from the large principle to the small valve, from the engineering development to the test design how to release the risk, from the limit depth to the yield strength, the depth of calculation, from the soldiers to the captain... The deep submergence must be all the same. It took two years for the development team to carry out related research and test tests, and did countless experiments. All kinds of situations in the deep submergence have been taken into consideration and guaranteed by these measures. A submarine accident is like a person suffering from a serious illness. Its not a day to get sick. Submarine incidents are not instantaneous. There will be harbingers. Every diving depth will be monitored. Once deviating from the preset, there are solutions or emergency floatation. You are the first deep submersible, isnt it afraid? Someone asked him. Im afraid I must have no idea! We sort out every possibility, so we are fearless. Wu Chongjian said, we must not engage in scientific experiments without any risk or adventure. We will never do it! To demonstrate the scientific and rigorous attitude and to tell the public, let the participants be convinced. The most proud of Wu Chongjians team is to take part in the deep submersible experiment, with 7 generals and a deputy ministerial cadre, the record of the world is unique in the history of the submarine. So far, Wu Chongjian has taken part in the three extreme deep diving as the head of technology. International efforts to build good Chinese submarines - It is a blessing for our generation to fight for the rise of China. Wu Chongjian is a real martial arts man who grew up in Huang Xing Road, Hankou. In his student age, he was famous for his fame. He called himself fanatical math enthusiasts, and he finished high mathematics in high school. He was a follower of Professor Li Guoping of Wuhan University. Not only did he learn well, he was also the champion of the long distance race in school. In the 1978 college entrance examination, he was admitted from the alma mater Wuhan eight middle school to the Harbin Institute of Ship Engineering (now Harbin Engineering University). More than ten years later, in 1991, Wu Chongjian received a scholarship from Bao Yu Gang and was sent to University of Southampton. Push the bike and whistle. In the early morning, on the campus of University of Southampton, students can always see a tall Chinese student running backward and heading for the direction of the dormitory. People do not know that the Chinese student has worked in the laboratory all night. One week for a month, this is Wu Chongjians work rhythm abroad. Why do you spell that? The masters gathered here, all over the place are gold, can they sleep? Hurry up! In Wu Chongjians mind, the masters ideas and ideas are more precious than gold. Diligence and talent, Wu Chongjian received the favor of tutor, world-renowned expert and vibrant energy inventor Robert White. Under the recommendation of White, Wu Chongjian, who graduated from the undergraduate course, took the doctor directly and became a formal researcher in the Institute of acoustical and vibration research at University of Southampton. The quasi periodic structure vibration energy flow study became one of the two important achievements of the 1992 Annual Research Institute, which was exhibited at the University and triggered a strong response. Wu Chongjian returned to the research of naval ships after his return to school. The basic theory of floating raft isolation is solved directly, and the quality effect tuning effect and mixing effect are put forward to realize the first application of floating raft isolation technology for Chinese ships. As the chief architect of the dragons surface support system, we have achieved the leap from scratch in our deep-sea scientific research equipment. The system of distribution and recovery of the water and water surface of the dragon has reached the leading level in the world, and the two core technology constant tension system and the heave compensation system have been successfully applied to the deep sea development. In January 8, 2018, the national science and technology award conference, the Jiao long manned submersible research and development and application of the national scientific and technological progress award first prize, Wu Chongjian third stand on the highest podium. Prior to that, he was awarded the first prize and the first prize of national science and technology progress. There is a German submarine model in Wu Chongjians office. How many times did anyone want this model? He didnt agree. Match the worlds most advanced submarines, and strive to build Chinas good submarine . Wu Chongjian set a goal for himself and his team. If the past efforts were the first performance subversion, Wu Chongjian led the team to target battlefield design equipment with system reconfiguration and measurement design to achieve second performance subversion. Some people say that the survival environment of Chinese submarines is not good enough. This is because our submarines are developing too fast, and some important researches such as cabin environment are lagging behind in the process of high-speed development. Wu Chongjian revealed that the cabin environment will become better and better in the future. We still have one last mile ahead of the world. It is a blessing for our generation to set up high mountains and go deep into the sea and fight for the rise of China. Wu Chongjian said. The source of this article: Global Times - global network.
