飞翔列车普通火车在行驶时受到的空气阻力和轨道摩擦力很大,这样就白白耗费了很多燃料。东京大学的一个科学小组正在研究一种新型的空气动力学列车,可以有效解决这个问题。这种火车看上去更像是一架飞机,带有四个空气动力学翅膀,还有两个螺旋桨。全速前进时,列车可以高出轨道10cm飞行,节能而且速度快,时速可达500km。
The ordinary trains of a flying train are exposed to a lot of air resistance and track friction, which consumes a lot of fuel in vain. A scientific group at the University of Tokyo is studying a new kind of aerodynamic train that can effectively solve this problem. The train looks more like an airplane with four aerodynamic wings and two propellers. At full speed, the train can fly 10cm above the track, save energy and speed, and the speed can reach 500km/h.
