中日聯合研製世界最快的懸浮列車

A high-speed aerotrain that could run 400 to 500 km per hour is being developed by China and Japan in a joint effort.

中國和日本正聯合研發一款時速可達400-500公里的高速氣動懸浮列車。

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.

有關專家透露，這種氣動懸浮列車不會使用如煤炭、天然氣或電力這樣的傳統的燃料資源，並預計其將改變世界的交通系統。

Trial manufacturing and test runs of the first and second generation aerotrain have been conducted in Japan, said Lai Chenguang, a professor at Chongqing University of Technology, who is participating in the project.

據重慶理工大學參與該項目的教授賴晨光介紹，高速氣動懸浮列車第一代、第二代樣式試製及實車試驗已在日本進行。

The train will be fully powered by natural energy, reducing costs while improving speed, Lai noted.

賴晨光指出，這款列車將完全採用自然能源驅動，從而降低了成本還提高了速度。

"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," he said.

他表示：“如果高速氣動懸浮列車以時速500公里運行，其能耗僅爲當下高鐵的1/3、磁懸浮列車的1/6。”

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.

環形擾流器的新設計是該氣動懸浮列車的一大亮點。與往往產生不穩定的氣流的傳統、垂直的擾流器不同，環形擾流器可以將升阻比提高30%到40%，極大地提高了運行的穩定性。

In addition, the load capacity of the train also will be enhanced thanks to the new design.

此外，得益於新設計，這款列車的負載能力也將得到提升。
