Professor: 4 km per hour fly iron technology immature government to be involved

The original title: 4 km per hour Flying iron behind: technology immature, called for capital and government intervention high-speed flight train renderings. On August 30, China Aerospace Science and Industry Corporation (hereinafter referred to as “Aerospace Science and Technology”) in the third China (International) commercial aerospace summit forum to vote heavy, announced that the joint Domestic units, carried out a “high-speed flight train” research and demonstration, the maximum speed of up to 4000 km. With this more than 3 times the speed of sound, let the public address him as “flying iron.” The so-called “high-speed flight”, the principle that is the use of vacuum pipes and superconducting magnetic levitation technology to achieve supersonic “near-ground flight”, known as the future of human “fifth mode of transport.” In fact, China as early as 2000 has been introduced before and after the concept of vacuum pipe magnetic levitation, nearly twenty days, the outside world is very little attention, the limelight is the Silicon Valley “Iron Man” Elon Musk (Elon Musk) In 2013 put forward the “super high iron” overshadowed. At present, on a global scale, countries that study vacuum transport maglev traffic are Switzerland, the United States and China. Zhao Yong, director of the Southwest Jiaotong University, Changjiang scholar professor, superconductivity and new energy research and development center director Zhao Yong in the surging news ( interview, said, “This technology needs to cause social concern.” Zhao Yong, Aerospace science and engineering at this time publicly announced the project, “not to say that this technology has matured, but the need for industrial sector intervention, the state government should have invested, the first technology developed.” Zhao Yong is China’s high-temperature superconducting field A doctor, was removed from Italy, Australia and Japan 13 years later, he returned to the Southwest Jiaotong University, Southwest Jiaotong University Department of Materials Science and Engineering Distinguished Professor of Yangtze River scholars, the first batch of foreign outstanding young fund winner. Zhao Yong at that time, “Southwest Jiaotong University is the most suitable for superconducting maglev research place.” According to Zhao Yong said, Zhao Yong team is the first international high-speed flying train industry alliance one of the members. Prior to August 30, Aerospace Science and Technology said that specifically for the “high-speed flight train” project, combined with more than 20 domestic and foreign scientific research institutions, set up the first international high-speed flying train industry alliance, the current team has related Field of more than 200 patents. This industry alliance is also known as the “national team” in the field of vacuum pipe maglev research. Zhao Yong also revealed that “Aerospace Science and Technology of the current program, the basic idea is to put forward in accordance with our book, specifically on the design of the magnetic side is to help us to complete.” Zhao Yong’s book is published in 2009, “speed Car system overview “, which is the world’s first system of vacuum tube magnetic levitation technology monographs. The other author of the book is Liu Benlin, according to Liu Benlin on surging news, said he and Zhao Yong for the University of Science and Technology of China Department of physics students, their own in 2005 contact with vacuum pipeline traffic. It is worth mentioning that, in the eyes of outsiders, Liu Benlin is a passion for new things “folk research enthusiasts”, not in the formal scientific research institutions. However, whether it is Zhao Yong or Liu Benlin, the speed of 4,000 km per hour is particularly cautious attitude. Zhao Yong said, “I have been emphasizing the speed of 1000 km this first step of the key and important, when you have not achieved when the 1000 km speed, talk about 4000 km speed meaning is not big.” Temporary speed of 4000 km, Exciting about the people “Aerospace Science and Technology announced on August 30, high-speed flight project landing will be in accordance with the maximum operating speed of 1000 km / h, 2000 km / h, 4000 km / h three step strategy gradually. The first step through the 1000 km / h transport capacity to build regional intercity flight train traffic network, the second step through the 2000 km / h transport capacity to build national super city group flight train traffic network, the third step through the 4000 km / h transport capacity Construction “along the way” flying train traffic network. Aerospace Science and Technology also on the “high-level flight” high hopes, and ultimately become the following aerospace, high-speed rail, nuclear power after the “new Chinese business card.” However, this grand blueprint has not yet given a timetable for the response. Zhao Yong said, “This vision we can simply mention that this is enough, but do not spend too much energy on this.We want to really 1000 km speed technology developed first, on this basis to accumulate enough experience “But Zhao Yong also said,” Aerospace Science and Technology is also very meaningful, is the first in the field of vacuum pipe made of the Union, is very worthy of encouragement, you can also inspire people. “But Zhao Yong believes that to achieve” super Flying train “no shortcut. “This is a project problem, first from the laboratory, to the pilot, and then to the project stage, this law is to be so real to go.We are now even the laboratory data has not come out, from this vision Very far. “In 2011, Zhao Yong team developed the world’s first vacuum pipeline high-temperature superconducting maglev train test system, the system track diameter of 3 meters, the minimum pressure of 2000 Pa pipe, magnetic car with a linear motor drive. At present, this first generation of experimental models has been removed. In January 2016, Zhao Yong team to complete the second generation of vacuum pipe high temperature superconducting maglev train system construction, the system for the first time using the “wall” type of operation, that is, 6.5m diameter ring track laying on the ring metal wall, so that the maglev along the wall High speed. The research team believes that in the structural mechanics, the second generation system effectively increases the centripetal force of the maglev along the loop and prevents the maglev from tangential to the track, resulting in higher operating speed and safety stability The In May 2016, the system completed the first phase of debugging, speed of 108 km; October 2016, the system completed the second phase of debugging, speed of 150 km. Zhao Yong told surging news, “At present, our laboratory in the high-temperature superconducting maglev can do speed160 km, this should be the highest speed of the laboratory. “The difficulty of the laboratory system is that” the site is limited, can only be made of circular, circular radius of a small radius of centrifugal force is very difficult to do it. At present, the field of superconducting magnetic levitation is recorded in Japan, and Japan uses low temperature superconducting maglev technology with a speed of 603 km per hour, and the technology industry is also mature. 505 km of superconducting magnetic levied high-speed railway, is expected to be opened to traffic in 2027. Zhao Yong said, “Japan’s speed is in the middle of the dense atmosphere to achieve, if the dense atmosphere into a low-pressure pipeline, then 1000 km per hour theory is achievable. “But whether it is a vacuum pipe, or high-temperature superconducting maglev technology, or the combination of these two,” domestic and foreign are blank, there are many core technologies to develop. In this book, the book on the design of the vacuum pipe, speed car (compiled: similar to high-speed flight) system transfer cooling, speed drive and steering, speedway design, emergency rescue and other aspects of the discussion , But until now, these problems are not mature program.Zao Yong mentioned that the vacuum pipe, for example, such a large volume of the vacuum system to establish and maintain, to do low cost is a big problem. Laboratory can not afford the high Costs In addition to the gaps in the field of technology, “high-speed flying trains” have to face high development costs, and this may be one of the reasons for the high-profile announcement of the project. Aerospace Science and Technology had mentioned, ” Commercialization, market-oriented model “to achieve this project.Zhuyong said,” do need the capital market and the country’s attention, because it is not only from the technical level can be driven, is involved in a wide range of high-tech. Up to now, the capital market is basically not involved, the country directly in the vacuum pipeline investment is basically no. “” Now is the need for relevant agencies to jointly develop the technology, rather than that the technology has matured. Need to intervene in the industry sector, the state government should have investment, the first technology developed first, the school which can only be used for reference. “Zhao Yong said that even if the team for Zhao Yong, if you want to further promote the experiment, we must also get more money and national policy support in Zhao Yong’s vision, the project must be from the laboratory to the outdoor.” Outdoor experiment first need the venue , At least 1 km or 2 km of the pipeline to do pre-test, the test at least tens of kilometers, Japan 600 km per hour of the maglev line has more than 30 kilometers of the line, according to this ratio, 50 to 100 km pilot line Is necessary. “Zhao Yong that these steps are essential,” without these tests, you do things out who dare to use? In this above repeatedly test, given the protection of security, so as to be extended to the project up. “The establishment of outdoor vacuum tube magnetic levitation model is not a high cost of the laboratory can afford.” Investment is certainly a hundred million units, you can analogy, the subway cost is 600 million yuan per kilometer -10 billion, with reference to this The numbers are not what our lab can do. “Masco released a white paper in 2013, proposed the” super high-speed rail “concept, claiming that the San Francisco to Los Angeles super high-speed rail train can reach a maximum speed of 1200 km, the cost of 6 billion -100 billion, only the California high-speed rail project ten The price of the speedway system will certainly be more expensive than the high-speed rail, the subway will be more expensive, It is impossible to avoid this problem. “It is worth mentioning that, in view of the current study of vacuum pipeline train country, only Switzerland has received government funding. Switzerland by Dr. Rudolf Reese (R. Nieth) in 1974, the concept of underground vacuum tunnel maglev train , Which was the “Swiss subway” and received the initial study by the Swiss government in 1985. Reese and his team in 1999 wanted the Swiss Federal Parliament to submit a research report that presented specific technical options. “Swiss Metro” has been stagnant since 1999, the Swiss Federal Parliament in 2005 decided to no longer promote the project, while the United States is now relying on private financing. “Super Rail” Hyperloop One in October 2016 announced the completion of the A $ 50 million C round of financing with a total financing of $ 160 million. Hyperloop One was founded in 2014 by Uber Early Investor Shervin Pishevar, Former SpaceX Engineer Brogan BamBrogan and Rob Lloyd (Chief Executive Officer, Hyperloop One) Local time on August 31, Masque in their own personal Instagram account Announced that Tesla’s super-high-speed rail train reached 355 kilometers per hour, breaking the previous time the University of Munich WARR Hyperloop team 324 kilometers per hour speed.However, the “super high-speed rail” technology is not mature and need a long waiting schedule, Richard Anderson, president of American Irons, told the local time on September 5 that he did not believe that the concept of super high-speed rail made by Maske could be achieved in a short time And more than traditional rail transport, Lloyd said after the second phase of the test, “the company’s current focus is really and the government and customers around the world for in-depth business discussions. Our focus is on the transfer, not just technology, but commercialization. “
