according to the newsis news agency of South Korea on July 21, a scientific research project of Ulsan University of science and technology of South Korea was implemented on September 1 of the same year; The standard stipulates that the experimental equipment loads a generation of ultra-high speed transportation technology at a constant speed. After the project is realized, the train operation time from Seoul to Busan, two major cities in South Korea, can be shortened to 16 minutes

while looking forward to technological breakthroughs and policy support, yushanke University of Technology said on the 21st that it took the lead in carrying out the ultra-high speed transportation system project in South Korea, and is developing core technologies before closing the oil return valve

according to the introduction, this project is a super high-speed rail project by putting the train into a vacuum pipe for transportation, such as computer travel. There is no air resistance in the vacuum pipe, and the maximum speed can reach 1200km/h. This speed exceeds the aircraft speed per hour and is four times faster than the existing high-speed trains in South Korea

the project has invested 1.4 billion won (about 8.26 million yuan) in 5 years. At present, the school has obtained the key technologies for reducing air resistance and realizing vacuum, and is conducting further research on the train and subsequent technology development

the research team is composed of professors from the University and the majors of power engineering, electrical and electronic computer engineering, design and ergonomics, as well as technical support from the Korean Machinery Research Institute and other relevant units, mainly focusing on the friction and air resistance generated by the train during operation. For this reason, the researchers designed an air compressor built in the front of the train. The air sucked into the front end is released at the end of the train, which can reduce the resistance at the front of the train and increase the power

the "super high-speed rail" with the above characteristics has attracted the attention of the world since it was proposed by American SpaceX company in August 2013

it is understood that the "super high speed rail" in South Korea does not adopt the train and propulsion system designed by SpaceX company using air pressure difference, but adopts independent technology. This scheme uses the magnetic force formed between the seats on the same side to lift the train for propulsion, but this scheme has the disadvantage of high power consumption. Researchers plan to use smart power distribution stations, including solar energy and fuel cells, to increase power supply within the operating range
