The air-dredging and resistance-reducing wheel-driven magnetic suspension rail train generates a suspension effect by utilizing the principle that magnetic suspension is generated by electromagnetic repulsive force and suction force, adopts wheel-driven and guide, adopts an air-dredging and resistance-reducing technology, and is characterized in that the air-dredging and resistance-reducing technology is used on the basis of the technology of the magnetic suspension rail train; the jet flow drag reduction technology can be used as a beneficial supplement. 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 magnetic suspension rail train can run in a virtual vacuum tube, but actually, the safe speed of the train is limited due to factors such as the mechanical performance of wheel driving and the air-dredging effect of the air-dredging and resistance-reducing technology. The streaming air flow on the surface of the vehicle body is in a low vacuum state, large energy consumption is still caused, and at the moment, the jet flow resistance reduction technology is shown as a beneficial supplement effect.

    疏气减阻轮式驱动磁悬浮轨道列车利用电磁斥力、吸力产生磁悬浮的原理使其产生悬浮效果,采用轮式驱动和导向,并采用疏气减阻技术,其关键特征就是在磁悬浮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。从理论上来说,以超高速行驶时,采用疏气减阻技术,疏气减阻轮式驱动磁悬浮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,列车的安全车速受到限制,其车身表面的绕流气流处于低真空状态,仍造成较大能耗,此时,射流减阻技术作为有益补充的效果便得以显现。
