Aerodynamics of String Transport

Dear colleagues, we continue to acquaint you with the articles of the technology developer, explaining the principles of its work and advantages compared to competitors. Today we will talk about the aerodynamic characteristics of the transport, on which its efficiency and economy depend. This parameter affects the speed, fuel consumption and cost of transportation. The rolling stock uses the technology that allows achieving outstanding performance in this area.

As a rule, at a high speed, transport spends up to 90% of energy to overcome aerodynamic resistance. Moreover, with increasing speed, air resistance increases quadratically. Added to this is the wing-in-ground effect – an aerodynamic phenomenon that occurs between the road and the car. To overcome it, the engine needs to work harder, increasing energy consumption.

In string transport, the mentioned problem is solved with the help of a string-rail overpass. The location of the track structure above the ground eliminates the wing-in-ground effect. Thanks to the streamlined body of the rolling stock, the energy consumption of vehicles is effectively reduced. In addition, they can safely accelerate to 150 km/h (high-speed pod up to 500 km/h). All this makes string transport and infrastructure complexes a truly advanced solution.

The high-speed model deserves special attention: its drag coefficient was reduced to 0.06. For comparison: among the cars that are leaders in this indicator, the aerodynamic drag coefficient can be, for example, 0.175.

It becomes obvious that the aerodynamic performance of string transport, combined with its other advantages, provides high efficiency and low operating costs for rail electric vehicles.
