中日联合研发时速400km悬浮列车
A high-speed aerotrain that could run 400 to 500 kilometers per hour is being developed by China and Japan in a joint effort, Chinese media Chongqing Morning Post reported.
《重庆晨报》报道，中国和日本正在联手研发一辆时速400至500公里每小时的高速悬浮列车。
The aerotrain doesn't run on traditional fuel resources such as coal, gas or electricity, and is expected to change the world's transportation system, according to experts.
Trial manufacturing and test runs of the first and second generation aerotrain have been conducted in Japan, said Lai Chenguang, a professor of Chongqing University of Technology, who participates in the project.
The train will be fully powered by natural energy, reducing costs while improving speed, he noted. "If the train runs at a speed of 500 km/h, the energy it consumes is only 1/3 of that consumed by current high-speed trains, and 1/6 of the maglev trains," Lai said.
The new design of an annular spoiler is a major highlight of the aerotrain. Different from the traditional, vertical spoilers which tend to produce unstable airflow, the annular spoiler can increase the lift-drag ratio by 30% to 40%, vastly improving the operation stability.
In addition, the load capacity of the train will also be enhanced thanks to the new design.
