– Open call for local governments from the 17th… Core technology development R&D preliminary application process –
□ The Ministry of Land, Infrastructure, and Transport announced that it would promote a public contest to select a site for a test bed for 'development of hypertube (Korean hyperloop) technology' targeting local governments across the country for about a month from June 6th.
< Overview of Hypertube >
◈ (Concept) A transportation system capable of driving at a speed of 0.001 km per hour or more by propelling and levitating a vehicle with magnetic force in a sub-vacuum (0.01 to 1,000 atmosphere) tube without air resistance.
☞ Possesses potential to simultaneously satisfy 'aircraft speed' + train 'access to city center'
◈ 3 components of the system
‣ (Sub-vacuum tube) Provides a sub-vacuum (0.001 to 0.01 atmosphere) environment, infrastructure that serves as a driving passage
‣ (Propulsion/Floating Track) A track that levitates and propels the vehicle by magnetic force
‣ (Vehicle) A vehicle that runs while keeping the cabin airtight from sub-vacuum
ㅇ At the site selected through this competition, a 12km-long sub-vacuum tube and test center, which are the necessary infrastructure for research on the development of hypertube core technology, will be installed.
* In order to realize the subsonic speed of 1,200km/h, a 30km-long straight site is required, but as a result of the preliminary investigation, it was judged that such a location would be difficult to obtain.
□ Globally, the demand for high-speed movement between large-area bases is increasing and the value of time in using public transportation is increasing due to the improvement of the quality of life.
ㅇ In the United States, after the hypertube received attention as a high-speed transportation method that would be competitive in terms of speed and cost, international competitions and test runs were promoted centering on startups, and Virgin Hyperloop conducted actual driving tests* there is a bar
* Achieved 387km/h through the unmanned driving test (Dec. 17.12) and achieved 2km/h through the manned driving test (two people) (Nov. 172)
ㅇ In the case of the magnetic levitation method used for vehicle propulsion, Japan has achieved the world's fastest speed and is constructing a commercial route. However, it is operated in a state of friction with air, which is far from a hypertube.
* The maximum speed of the maglev train reached 15 km/h in '603 and the goal is to open the Tokyo-Nagoya (27 km) section in '286, and the operating speed is expected to be about 500 km/h.
□ Meanwhile, core technology research has been conducted in Korea as well, and the Korea Railroad Research Institute has proven* the possibility of realizing high-speed transportation within the tube by successfully driving at a speed of 20 km/h through a scaled-down model test (1/17) in 1,019.
* It has been recognized that it is difficult to achieve a speed of 700 km/h or more within the tube.
ㅇ The Korea Institute of Construction Technology has secured basic technology by constructing an ultra-high-density concrete sub-vacuum tube with a diameter of 21 m and an extension of 4 m in '10 and maintaining a pressure of 0.001 to 0.01 atm for more than 30 minutes.
□ As such, hypertube technology has not yet succeeded, and the reason for these efforts is that who secures the core technology first is the key to preoccupying the relevant market.
ㅇ Although the international railroad market is growing every year, only vehicles and parts certified for safety can be used, so the reality is that the country that succeeds in developing the technology first dominates the market.
※ The railroad market according to the existing method is KRW 250 trillion, and it is growing by 2.6% every year.
□ Recognizing the need for systematic R&D in a situation where preemptive efforts for super-gap science and technology are accelerating, the Ministry of Land, Infrastructure, and Transport has been cooperating with the Ministry of Science and ICT to conduct planned research for hypertube technology development. has been promoting
* (Korea Railroad Research Institute) Planning of 「Intercontinental High Speed Rail System Development Project」('18.8~'20.8)(KISTEP) MSIT Innovation Challenge Project 「Hypertube Technology Development」planning ('21.5~'22.2)
ㅇ Through planning research, we set a R&D goal that it is necessary to first implement a sub-vacuum environment in the test bed and to develop and verify the core technology required for high-speed driving, rather than putting it into practical use as a means of transportation at the current level.
□ After selecting a test bed, the Ministry of Land, Infrastructure, and Transport plans to apply for a preliminary feasibility study this year and start R&D projects in '24.
ㅇ In the initial stage of the study, a short section (1~2km) maglev track is first constructed, and the success of the propulsion and levitation system is checked with a test run of 150~200km/h, and then the main test track of 12km is constructed.
ㅇ The site selected this time will be used for core technology development for about 10 years* after the start of the research.
* Core technology development 4 years, test bed empirical research 5 years
□ On the other hand, local governments wishing to host a test bed can propose a site through consultation with the 'regional and basic local governments', and for efficient business promotion, the number of sites that can be proposed is limited to one per regional municipality.
ㅇ The public offering for this project is entrusted by the Korea Agency for Infrastructure Technology Advancement (KAIA).
ㅇ Details related to the competition will be announced through the Ministry of Land, Infrastructure, and Transport website (www.molit.go.kr) and Korea Agency for Infrastructure Technology Advancement (KAIA) (www.kaia.re.kr). .
□ To ensure fairness and professionalism in the site selection process, a 'site selection committee' composed of experts will be formed, and a 'site investigation team' to investigate the suitability of the site will be operated.
ㅇ The site proposed by the local government will be selected after comprehensively evaluating site requirements such as whether the required extension required for research is satisfied, project promotion conditions such as construction cost, and the local government's support plan.
□ Ministry of Land, Infrastructure, and Transport Director Kang Hee-eop said, “Hypertube is an innovative means of transportation that can bundle major cities in Northeast Asia into commuting areas, but it is a challenging task that requires a lot of effort to develop core technology and research subsequent practical use.” ,
ㅇ “The test bed will be selected fairly and objectively as it is the first step in this R&D journey, and we hope that a good location will be proposed so that the R&D can proceed successfully,” he said.

2. Principle of driving
□ Promotion
ㅇ (Propulsion) Propulsion with the pushing and pulling force of the vehicle electromagnet and the ground electromagnet
ㅇ (Propulsion control) The track controls the vehicle propulsion, and the coil polarity of the track is linked according to the vehicle speed (changes the track polarity about 1,000 times per second when driving at 1 km/h)
□ injury
ㅇ (Principle) When the vehicle moves up, down, left and right from the original position, the induced current to return it to the coil (figure 8) of the track generates suction and repulsion to maintain balance
* (levitation force) When the vehicle body moves down (up), it rises up (down) by the induced current (guide force) When the vehicle body moves left/right, it moves in the opposite direction by the induced current
ㅇ (Characteristic) Like an airplane, it goes on wheels at first, and then floats at 150 km/h.
