The world's first new energy empty iron is coming!
On the afternoon of November 21st, at the Zhongtang Empty Iron Industry Base in Chengdu Shuangliu (Weibo) Airport Economic and Technological Development Zone, the chief designer of the new energy empty iron and the academician of the Chinese Academy of Sciences announced that the world's first new energy air railway (referred to as the empty iron) The test line was successfully put into operation. It puts the rails in the air, hangs the cars in the air, does not compete with people, does not compete with the car, does not compete with plants for living space...
On the same day, including the reporters of the Huaxi Dushi Bao, hundreds of people successively boarded the "Panda" empty iron and took the test. Wearing a red flower, the body of the car is dressed as an empty iron with panda elements, and “flying†at a speed of 60 kilometers per hour... thus opening up the imagination of improving urban congestion.
Empty iron first experience
The first show was "tight", it was a little trembling
On the afternoon of November 21st, the empty iron with the decorative elements of pandas was on the road, and the reporter of Huaxi Dushi Bao also experienced the feeling of a "Peter Pan".
This new energy empty iron test line is a U-shaped white rail that is erected above 5 meters and has a total length of 1.4 kilometers. The entire test line consists of a passenger station, a main line track, a secondary line, and trains, static adjustments and other related equipment. It can completely simulate the performance of straight lines, corners and climbs of new energy empty irons in actual operation.
Before and after the empty iron, there are drivers who open the way for everyone. Like a subway, the cockpit door is separated from the passenger compartment by a door. Inside the cabin, the pillars with blue seats and armrests are flushed, and the seats are placed on the left and right sides, or the overall feel is somewhat crowded. It is said that the maximum carrying capacity of an empty iron is 230 passengers.
Standing in the carriage, through the glass window, the line of sight is extremely wide, just like standing on the second floor overlooking the distance. The test line track simulates different road conditions in the city. There are curved roads and uphill slopes. The maximum slope of the line is six thousandths and the minimum turning radius is 30 meters. "Please pay attention to the experience, and now the cornering stage." Wang Kai, the "navigator" on the empty iron, said that the setting of these indicators is designed according to the most complicated road conditions in the city. In other words, as long as this situation Under the simulation can be successful, then the city's other road conditions can be adapted.
However, the reporter felt that the bumps in the carriage were quite obvious. A passenger placed a bottle of mineral water in the compartment to test its stability. Seeing the water continually pulsing in the bottle, some passengers joked: "The sporty carriage is like a massage."
For feedback on bumps in the car, Yan Ming frankly, this may be related to the weld. Next, they will further collect test parameters, improvements and optimizations.

Speed ​​/ it "flights" at 60 km/h
Yan Ming said that the car has become the daily means of transportation for most urban residents, which makes urban ground traffic overwhelmed and has become an important factor in environmental pollution. He believes that the railway suspended in the air (referred to as the empty iron) is an inevitable choice for the development of three-dimensional transportation in modern cities.
What is the speed of the empty iron? This is a matter of public concern. Yan Ming introduced that during the trial operation of the new energy empty iron test line, its speed was set at nearly 60 kilometers per hour compared to the speed of Japan and Germany. He believes that the speed of 60 kilometers per hour is enough for urban traffic. Because there is a site in which urban traffic can't be separated, it is not realistic to maintain the high speed of transportation for a long time. If the empty iron is suitable for use in the suburbs or scenic spots, there is room for speeding up. In the future, it is possible to increase the speed of the empty railway to 70 kilometers or 80 kilometers per hour.
Safety / high security, it never derails
Will the track in the air be at risk of derailment? How to ensure its security?
In his speech, Yu Ming particularly emphasized the high security of air railway operations. He further explained that the vehicle running gear is always enclosed inside the box-shaped track beam and there will never be a derailment event. The train will not collide with other objects on the air line, which fully guarantees the operation safety of the system.
Say that the empty iron is so safe, what operational risks may it face?
The biggest risk of the analysis is that the battery is exhausted and the empty iron is shut down in the air. If the empty iron stops in the air, how can passengers escape or evacuate? Yan Ming said that the team designed a plan to evacuate passengers. For example, the front and rear windows of the car can be opened, and a 5-meter-high slide can be placed. Passengers can take the slide to leave. You can also use a simple ladder to evacuate passengers, or you can drive another empty iron to pick up the trapped passengers.
Low cost / construction cost per kilometer is less than 100 million yuan
According to Yan Ming, the new energy empty railway has the advantages of low investment and short construction period.
He revealed that compared with the construction of the subway, the track and beam of the new energy empty iron are prefabricated by the factory, assembled on site, simple in construction, with little impact on the surrounding area and shorter construction period. After calculation, the cost of constructing an empty iron per kilometer is less than 100 million yuan. The construction cost per kilometer is only one-fifth to one-eighth of the subway, and one-half to one-third of the straddle-type monorail traffic.
Since the power used by the empty iron is a lithium battery, the operator can charge the electricity peak, such as charging in the middle of the night. On the one hand, it contributes to the balanced use of electricity, on the other hand, it can also obtain the lowest power cost.
Yan Ming introduced that compared with the suspension railways in Japan and Germany, he designed the empty iron to use the new energy lithium battery power pack as the power source. The lithium battery life of the new energy empty iron can be up to 4 hours depending on the power required to carry the number of passengers.
Use / more suitable for second and third tier cities or scenic spots
Can the emergence of empty iron change the problem of urban congestion? Will it become the mainstream transportation means of the future?
In this regard, it is obviously very rational: the empty iron is not a mainstream mode of transportation, but one of many modes of transportation, and is an important supplement to urban rail transit.
“There is a subway underground, there are light rails on the ground, and the road becomes more and more crowded. We set up an air railway and add one more to the entire ground and underground transportation mode.†He said that through the formation of urban three-dimensional traffic, to solve the heavy traffic. problem. He believes that the low construction cost of the empty iron and the short construction period make it more suitable for development in the second and third tier cities. In this type of city, the empty iron is likely to become the mainstream means of transportation for ordinary people.
Going to Shanghai, taking the maglev train has become a standard for many people to travel to Shanghai. Will the high-profile iron and steel industry also show its strength in the tourism industry? In this regard, Yan Ming believes that in the tourism industry, as long as the scenic spot is intentionally built, this will be a good development direction.
Charge / as city traffic, price or with the subway
If one day, the empty iron out of the laboratory, to the ordinary people's life, take the air of the air, will the charges be as expensive as the Shanghai Maglev train? Is it as close to the people as the subway price?
In this regard, Yan Ming believes that if its function is the city's main means of transportation, its price may be like the bus and subway, there are subsidies from the government, the price will be very close to the people. If it is mainly used in scenic spots, then its price may be like a sightseeing car, a cable car, a cableway, and the price will be higher than the daily transportation fee.
When do we get on the empty train?
Academician Yan Ming:
The fastest in the next year is best in Sichuan
Yan Ming introduced, next, this test line will simulate the normal passenger operation state, and carry out a running test with a total mileage of 10,000 kilometers to test the stability of the system under the condition of “repeated running†and optimize according to the actual situation. Enhance relevant parameters to enhance the corresponding functions, lay a solid foundation for the commercialization of new energy empty iron, enter the daily life of the public, and improve traffic congestion in China's cities. “It also lays the foundation for the next step to determine the implementation standards for new energy air-iron technology.â€
Since the empty iron has so many advantages, will this innovative product win the favor of the market?
According to Tang Tong, Chairman of the Board of Directors of Zhongtang Air Rail Group Co., Ltd., some cities in and outside the province have already thrown olive branches to them. Some cities have clearly expressed their desire to use air rails to open up air travel routes. Yan Ming said that he hopes that the first empty iron used in the market will be born in Sichuan, which has bred and produced empty iron. He believes that if you do it quickly, you can use it on the commercial line next year. However, this needs to be combined with local government planning.

The new energy empty iron uses lithium battery as the traction power, which has the advantages of green environmental protection, low noise, small land occupation, strong adaptability, low investment, short construction period, moderate transportation capacity, fast and punctuality, etc.
The construction period of new energy empty iron is short, and it can be completed in half a year to 8 months. Chengdu citizens can take the fastest next year.
â–¡ reporter Qian Qianting
Chengdu citizens can take the new energy air train as soon as next year, which was learned by the reporter on November 21 at the launching ceremony of the world's first new energy empty iron test line. The reporter also learned that the Zhongtang Air Rail Group, which is developing and investing in new energy and air railway projects, has now received cooperation intentions from many places outside the province.
According to Tang Tong, Chairman of Zhongtang Air Rail Group Co., Ltd., Chengdu currently plans to plan three new energy empty railway lines, two of which are located in the downtown area of ​​Chengdu, and a number of major attractions to be planned to connect the central city. It is 6.8 kilometers long and forms a “fine tourism new energy empty iron lineâ€, and the other is under planning. "The construction period of new energy empty iron is short, and it can be completed in half a year to eight months. Chengdu citizens can ride as soon as next year." Tang Tong said.
On September 30 this year, the world's first new energy empty iron held a hanging ceremony in Chengdu Shuangliu (Weibo) district, which means that another city's traffic mode will be born in Sichuan. On November 21st, the test line was officially launched. The new energy empty iron chief designer, Chinese Academy of Sciences academician Yu Ming introduced, next, this test line will simulate the normal passenger operating state, the total mileage of 10,000 kilometers of running tests to test the system in the case of "repeated running" Stability, and according to the actual situation, optimize and improve relevant parameters to enhance the corresponding functions, to lay a solid foundation for the commercialization of new energy empty iron, to enter the daily life of the public, and to improve traffic congestion in China's cities, "also to determine the new energy empty iron The technical implementation standards lay the foundation."
The empty iron, the suspended air monorail system, is different from the subway and tram, and is a kind of rail transit that runs on the air track. The new energy empty iron uses lithium battery as the traction power, and has the advantages of green environmental protection, low noise, small land occupation, strong adaptability, low investment, short construction period, moderate transportation capacity, and quick and punctuality.
At present, only a few countries such as Germany and Japan have built empty irons around the world. The empty iron in the introduction of experts is "significantly advantageous". Why has it not been built on a large scale in the world? Is there a market for vigorously developing empty iron? According to the analysis, the population density in Europe is not large, and the public transportation system is mature, and it is not so urgent for empty iron. "Reviewing China at this stage, the population is large, the traffic pressure is getting bigger and bigger, and the empty iron that does not hinder the existing road conditions will usher in a market with great potential in China." "At the same time, compared with the traditional high-voltage power transmission and transformation system used by the empty irons in Germany and Japan, the use of new energy sources is not only more environmentally friendly, but also more beautiful, and also reduces the cost in the power supply system."
It is understood that the test line has a top speed of 60 kilometers per hour and a maximum capacity of 20,000 passengers per hour. The construction cost per kilometer is only one-sixth to one-eighth of the subway. The construction indicators are fully adapted to commercial operations. Claim.
It is worth mentioning that this is a new modern transportation system with completely independent intellectual property rights. The 14 new patents and 38 proprietary technologies owned by the new energy empty iron project are the first in the world to complete the key technologies and series of vehicle models for airborne orbital trains, and first entered the field of China's empty iron manufacturing.
