The air-dredging and resistance-reducing pneumatic guide linear motor driven magnetic suspension rail train comprises key parts such as an air-dredging and resistance-reducing system, a train body magnetic suspension system, a linear motor driving system and a guide air cushion generation system, and is characterized in that an air-dredging and resistance-reducing technology is used on the technical basis 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 magnetic suspension rail train driven by the air-dredging and resistance-reducing pneumatic guiding linear motor can run in a virtual vacuum tube by adopting the air-dredging and resistance-reducing technology, but actually, the safe speed of the train is limited due to the air-dredging effect of the air-dredging and resistance-reducing technology, 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.
疏气减阻气动导向线性电机驱动磁悬浮轨道列车包含疏气减阻系统、车体磁悬浮系统、线性电机驱动系统和导向气垫生成系统等关键部分,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,疏气减阻气动导向线性电机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。
