Problems solved by technology

[0002] At present, the known means of speeding up trains based on high-speed railways is to use magnetic levitation to reduce the friction of the wheels on the rails. However, the disadvantages of the magnetic levitation method are: 1. The train cannot change tracks, unlike trains that run on conventional railways. Turnouts go from one track to another; one track can only accommodate one train running back and forth, resulting in a waste of resources
2. Since the maglev system relies on electromagnetic force for levitation, guidance and driving operation, once the power is cut off, the maglev train will have serious safety accidents, so the safety guarantee measures for the maglev train after the power failure have not been completely resolved
3. Strong magnetic fields will have adverse effects on human health, the balance of the ecological environment and the operation of electronic products

Abstract

The invention relates to locomotives and carriages in railway systems, in particular to a high-speed railway based aerodynamic aerotrain with simulated wings on a chassis of an aerotrain body. Simulated wings in airplane wing simulated structure are symmetrically mounted on the left side and the right side of each carriage and the left side and right side of the chassis of a locomotive. In order to achieve better effects, enable the aerotrain to run more stably and safely and prevent the simulated wings from external wind direction influences, wind shields are arranged on two sides of a rail and above the wings. By the aid of the simulated wings mounted on the aerotrain, uplifting force is generated under the action of airflow in relative movement to the aerotrain, raising force can be provided for the aerotrain in high-speed running, and accordingly pressure applied to rails by the aerotrain is reduced, and extra energy consumption and pollution are avoided since the force is generated aerodynamically. Further, the simulated wings are simple in structure.
