The air-dredging and resistance-reducing linear motor driven permanent magnet suspension rail train is characterized in that an air-dredging and resistance-reducing technology is used on the technical basis of an existing linear motor driven permanent magnet suspension rail train, and a jet flow resistance-reducing technology can be used as a beneficial supplement. Theoretically, when the train travels at an ultra-high speed, the air dredging and resistance reducing technology is adopted, an air dredging and resistance reducing linear motor drives the permanent magnet suspension rail train to run in a virtual vacuum tube, but actually, due to the air dredging effect of the air dredging and resistance reducing technology, the safe speed of the train is limited, and the train cannot run in the virtual vacuum tube. 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. The air dredging and resistance reducing linear motor driven permanent magnet suspension rail trains with various structural forms are similar and different in structure, and each air dredging and resistance reducing linear motor driven permanent magnet suspension rail train comprises key parts such as an air dredging and resistance reducing system, a train body permanent magnet suspension system, a linear motor driving system and a guide air cushion generation system.

    疏气减阻线性电机驱动永磁悬浮轨道列车的关键特征就是在现有线性电机驱动永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,疏气减阻线性电机驱动永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,但实际上由于疏气减阻技术的疏气效果,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。各种结构形式的疏气减阻线性电机驱动永磁悬浮轨道列车结构大同小异,都包含疏气减阻系统、车体永磁悬浮系统、线性电机驱动系统、导向气垫生成系统等关键部分。
