According to the air-dredging and resistance-reducing wheel-driven rail train, the air-dredging and resistance-reducing technology is used on the basis of the technology of an existing wheel-driven rail train, and the jet flow resistance-reducing technology can be used as a beneficial supplement and also can not be used. Theoretically, when the train runs at an ultra-high speed, the air-dredging and resistance-reducing technology is adopted, the air-dredging and resistance-reducing wheel-driven rail train can run in a virtual vacuum tube, but actually, due to the factors such as the mechanical performance of wheel-driven, the air-dredging effect of the air-dredging and resistance-reducing technology and the like, the air-dredging and resistance-reducing wheel-driven rail train can run in the virtual vacuum tube. The safe speed of the air-dredging and resistance-reducing wheel-driven rail train is limited, rarefied air still exists on the surface of the train and the train is in a low-vacuum state, and when streaming airflow on the surface of a train body is in the low-vacuum state and large energy consumption is generated, the effect of the jet flow resistance-reducing technology serving as a beneficial supplement is shown. The air-dredging and resistance-reducing wheel-driven rail train can use the air-dredging and resistance-reducing technology and the jet flow resistance-reducing technology at the same time to achieve the optimal energy-saving effect.
疏气减阻轮式驱动轨道列车是在现有轮式驱动轨道列车的技术基础上使用了疏气减阻技术,射流减阻技术可以作为有益的补充而使用,也可以不使用射流减阻技术。从理论上来说,当列车以超高速行驶时,采用疏气减阻技术,疏气减阻轮式驱动轨道列车可以达到在一条虚拟真空管中运行的状态,但实际上由于轮式驱动的机械性能、疏气减阻技术的疏气效果等等因素,疏气减阻轮式驱动轨道列车的安全车速受到限制,其表面还是存在稀薄的空气,处于低真空的状态,当车身表面的绕流气流处于低真空状态,产生较大能耗时,射流减阻技术作为有益补充的效果便得以显现,此时,疏气减阻轮式驱动轨道列车可以同时使用疏气减阻技术和射流减阻技术来取得最佳节能效果。
