“…These materials have been used in almost all experimental models of vehicles (manned and unmanned), developed to date. In particular, they were used in the first manned model of a magnetic levitation vehicle tested at Southwest Jiaotong University, China in 2000 [38], as well as in the first AMLT prototype of vacuum magnetic levitation transport in 1914 & 2014 [15,35] and in a full-scale, 200 m long and in HTSC-based model, built at the Federal University of Rio de Janeiro, Brazil, in 2014 & in Italy [39,40].

The Russian Federation is located at the crossroads of the trade routes of the Eurasian continent, where a significant volume of the transport flow of the world’s trade is formed. The transport potential of the territory of Russia, when implemented as an Integral Transit Transport System (ITTS), is comparable to the benefits from the traditional export of hydrocarbons and other raw materials. Analyzing the efficiency of transport systems, the key is the energy approach. The concept of ITTS is considered, based on all known and being developed transport lines, including high-speed vacuum magnetic levitation transport (VMLT). The fundamental problems are discussed being on the way to achieving the maximal speed, energy efficiency and throughput of VMLT. The preliminary findings are presented obtained from experiments on the test model of the VMLT route. It is concluded that there is a need for a deeper study of the properties of magnetic and superconducting materials in extreme high fields, power and speed regimes to search for fundamentally new technical solutions for the creation of VMLT

Three-dimensional compressible flow simulations were conducted to develop a Hyperloop pod. The novelty is the usage of Gamma transition model, in which the transition from laminar to turbulent flow can be predicted. First, a mesh dependency study was undertaken, showing second-order convergence with respect to the mesh refinement. Second, an aerodynamic analysis for two designs, short and optimized, was conducted with the traveling speed 125 m/s at the system pressure 0.15 bar. The concept of the short model was to delay the transition to decrease the frictional drag; meanwhile that of the optimized design was to minimize the pressure drag by decreasing the frontal area and introduce the transition more toward the front of the pod. The computed results show that the transition of the short model occurred more on the rear side due to the pod shape, which resulted in 8% smaller frictional drag coefficient than that for the optimized model. The pressure drag for the optimized design was 24% smaller than that for the short design, half of which is due to the decrease in the frontal area, and the other half is due to the smoothed rear-end shape. The total drag for the optimized model was 14% smaller than that for the short model. Finally, the influence of the system pressure was investigated. As the system pressure and the Reynolds number increase, the frictional drag coefficient increases, and the transition point moves toward the front, which are the typical phenomena observed in the transition regime.

In the high temperature superconducting maglev-evacuated tube transport (HTS Maglev-ETT) system, the air drag is the most principal resistance to the speed improvement and energy conservation. Considering the aerodynamic performance of the HTS Maglev-ETT system has great significance in practical application. As the first step, we experimentally explored the influence of velocity, blockage ratio and airshaft on the air drag of a running maglev vehicle at atmospheric pressure (95.6 kPa in Chengdu), coupled with the simulation by using the ANSYS-FLUENT software. The results preliminarily confirmed the feasibility of the aerodynamic experiments on the HTS maglev-ETT test system, as the drag is proportional to the blockage ratio and the square of velocity respectively. Moreover, airshafts are suggested to be added in the future design of the HTS Maglev-ETT system, aimed at its good relief on the air drag displayed in the experiment and simulation.
