The train with a speed of 4000 kilometers per hour will come and run in the vacuum pipeline.

From Beijing to Wuhan to participate in the third China (International) commercial space Summit Forum, the reporter took a high-speed railway, a distance of 1152 kilometers, and ran for more than 4 hours.

 

In this forum, the science and Technology Daily reporter learned that China aerospace industry group company is advancing the "high-speed flight train" project, or will reduce the Beijing and Han journey to less than half an hour.

 

The 1 hour economic circle of the domestic super city group will be formed

 

Liu Shiquan, deputy general manager of China aerospace industry group, introduced that the high-speed flying train is a new generation of transportation tools developed by the combination of supersonic flight technology and rail transportation technology through commercialization and marketing mode.

 

The maximum speed of the train can reach 4000 kilometers per hour, not only 10 times faster than the ordinary high-speed rail, but also 5 times faster than the civil aircraft. With it, people living in Beijing go out at 7 in the morning and can go to Wuhan calmly to attend the 10 o'clock meeting. As the next generation transportation system, the project is brewing a technological change that can change our way of life.

 

The reporter learned that the high-speed flying train is a transport system that uses low vacuum environment and supersonic shape to reduce air resistance and reduce friction resistance by magnetic levitation, so as to achieve supersonic "near ground flight". It can not only draw near the space-time distance between cities, but also have the advantages of unaffected by weather conditions, no fossil energy consumption and seamless connection with urban subway, which can be called the development trend and technical height of the future traffic field.

 

Will the passengers discomfort at such a speed? Mao Kai, the three assistant director of the third courtyard of the aerospace industry group, and the head of the high speed flight train project, told the science and Technology Daily that the project would design the most suitable acceleration according to the passengers' feelings and give a linear process to the acceleration and deceleration. "It must be more relaxed than the plane takes off."

 

After the project is completed, it will not only change the way of human travel, but also rewrite the economic layout of China and the world, speed up the allocation of domestic resources, and form a 1 hour economic circle of the super city group. At present, there are 3 companies worldwide announcing the development of the land transport system at a speed of more than 1000 km, including the HTT, Hyperloop One, and the China aerospace industry group. Two American companies started early, but the aerospace industry was the world's first enterprise to use supersonic speed related technology to put forward the supersonic ground transport system, with a higher starting point. In fact, maglev trains are not new, and have already been studied at home and abroad. But how will the high-speed train program achieve speed from hundreds of kilometres to thousands or even thousands of kilometers? Mao Kai said that the current maglev trains are mostly running in the open air, in addition to overcome the friction, but also to face air resistance. The project runs in a vacuum pipeline and the environment is different. In addition, there are several kinds of maglev technology. For example, the maglev train developed in Shanghai is the electromagnetic levitation technology imported from Germany. And the project chose high temperature superconducting magnetic levitation technology. This technology has a considerable foundation in our country. Mao Kai introduced that the development team is carrying out many key technology tackling problems. For example, superconducting magnetic levitation technology can not fully meet the needs of the project, and further enhance its capability. In the vacuum technology, our country has made certain accumulation through the manned space engineering, but the long vacuum pipeline has not been done, and there are challenges in the manufacturing technology and technology. However, he said, according to the basic principle, only a positive force between push and drag is needed to make the train speed up, so it does not need an absolute vacuum, otherwise the difficulty and cost of the project will be greatly increased. In addition, he said that although many technologies have been implemented in the laboratory, the transformation to engineering will be a difficult task for the project. The reporter learned that the implementation of the project has paid attention to the advantages of all parties, and has joined more than 20 research institutions at home and abroad, and established the first international high speed flight train industry alliance in China. At present, the team has more than 200 patents in related fields. Three steps to achieve the goal of "4000 kilometers" Mao Kai introduced, 4000 kilometers of the index is combined with the pre - judgment of technology, to meet the needs of the future use as much as possible. The speed, however, will not be achieved overnight. Reporters learned that the project will follow the three step strategy gradually landing flowering. The first is to build a regional intercity transport network by carrying capacity of 1000 kilometers per hour. "For example, from Beijing to Wuhan, to Shanghai, or from Wuhan to Chengdu and south to Guangzhou, the distance is between 1000 and 1500 kilometers." Mao Kai said that the second step of the project is to build a one hour transportation network between the national super city clusters through the capacity of 2000 kilometers per hour. Finally, the project will build a "one - way" traffic network through the capacity of 4000 kilometers per hour to form a new Chinese card following space, high speed rail and nuclear power. The reporter has learned that the project has chosen the most promising technical route in technological innovation, and realizes the security, feasibility and economy of the system through key technologies. In the business model, the model of "laying eggs along the way" and the transformation of the key technology products can be realized constantly. We will continue to combine the domestic and foreign superior teams to ensure the advancement of R & D strength.
