Two Application Issues of High Temperature Superconducting Maglev in the Evacuated Tube Transportation


Article Preview

Based on some special merits such as self-stability, energy-consuming-efficiency, less pollution, high reliability, and so on, high temperature superconducting maglev (HTSM) is one of the promising potential technologies among present Maglev technologies for the future evacuated tube transportation (ETT). In this paper, the possibility, the merits, and the demerits of the applications of HTSM in ETT system are investigated. Especially, two application issues, liquid nitrogen vessel on the vehicle and isolated gate set in ETT, are discussed and solutions are suggested. On the first issue, this paper suggests to install a pressure relief valve on the sealed liquid nitrogen vessel so as to reduce the liquid nitrogen vaporization in the vacuum tube. As for the second issue, this paper recommends to use HTSM permanent magnet (PM) track structure with a streamline separated gap between the surface of track and the bottom of liquid nitrogen vessel. Those guideway structure could fit to the isolation gate setting in ETT.
