The scientific name of super high-speed rail is supersonic aerodynamic train. This concept was first put forward by American mechanical engineer Oster in 1997, and obtained a technical patent. On this basis, elon musk, the "father of Tesla", put forward the idea of "super ring" in 20 13, that is, the prototype of super high-speed rail. In fact, it is a superconducting maglev train, which is a special means of transportation that runs at ultra-high speed in a nearly vacuum tube transportation system. Because the space used to transport passengers or goods is like a sealed capsule, it is also called "capsule train" figuratively.
Air compression and magnetic levitation are the basic working principles of super high-speed rail. In a completely closed pipeline, the air in the pipeline is pumped away along the running direction of the train, forming a state close to vacuum. Under the action of atmospheric pressure, like a giant with super vital capacity sucking a train with a straw, the train is "sucked" from one place to another like a fired shell. Magnetic levitation and vacuum can also basically eliminate the resistance caused by air resistance and friction, and then realize high-speed operation.
