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

中国和日本正联合研发一款时速可达400-500公里的高速气动悬浮列车。

The aerotrain doesn't run on traditional fuel resources such as coal, gas or electricity, and is expected to change the world's transportation¹ system, according to experts.

有关专家透露，这种气动悬浮列车不会使用如煤炭、天然气或电力这样的传统的燃料资源，并预计其将改变世界的交通系统。

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.

据重庆理工大学参与该项目的教授赖晨光介绍，高速气动悬浮列车第一代、第二代样式试制及实车试验已在日本进行。

The train will be fully powered by natural energy, reducing costs while improving speed, Lai noted².

赖晨光指出，这款列车将完全采用自然能源驱动，从而降低了成本还提高了速度。

"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 maglev³ trains," he said.

他表示：“如果高速气动悬浮列车以时速500公里运行，其能耗仅为当下高铁的1/3、磁悬浮列车的1/6。”

The new design of an annular⁴ spoiler is a major highlight of the aerotrain. Different from the traditional, vertical⁵ spoilers which tend to produce unstable⁶ airflow, the annular spoiler can increase the lift-drag ratio by 30% to 40%, vastly improving the operation stability.

环形扰流器的新设计是该气动悬浮列车的一大亮点。与往往产生不稳定的气流的传统、垂直的扰流器不同，环形扰流器可以将升阻比提高30%到40%，极大地提高了运行的稳定性。

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

此外，得益于新设计，这款列车的负载能力也将得到提升。
