“…Systems which use passive magnetic suspension, despite growing popularity, have not been used so far in professional and commercial technical solutions. However, there is a small number of academic research projects on the use of HTS in transportation systems, including SupraTrans (Schultz et al, 2005), Cobra Tram (Sotelo et al, 2011) and SuperMaglev (Wang et al, 2005). • the levitating cart is an axisymmetric solid body with six degrees of freedom;…”

The article presents the steps of modeling of the dynamics of a levitating cart of an unmanned aerial vehicle (UAV) magnetic catapult. The presented in the article innovative catapult is based on the Meissner effect occurring between high-temperature superconductors (HTS) and a magnetic field source. The catapult suspension system consists of two elements: fixed to the ground base with magnetic rails and a moving cart. Generating magnetic field rails are made of neodymium magnets. Levitation of the launcher cart is caused by sixteen superconductors YBCO, placed in the cart frame supports. Described in the article model contains the system of Cartesian reference frames, kinematic constrains, equations of motion and description of forces acting on the cart as well as exemplary numerical simulation results.

“…On 12 January 2004, the project decision meeting of a super-high-speed ETT HTS Maglev train was held at SWJTU. Professor Jia-Su Wang reported on an ETT HTS Maglev train proposal which promised more than 600 km h −1 [60]. But, as yet, neither a real scale nor an experimental HTS Maglev vehicle system has been built operating in an ETT or low-pressure tube (LPT).…”

There is universal agreement between the United Nations and governments from the richest to the poorest nations that humanity faces unprecedented global challenges relating to sustainable energy, clean water, low-emission transportation, coping with climate change and natural disasters, and reclaiming use of land. We have invited researchers from a range of eclectic research areas to provide a Roadmap of how superconducting technologies could address these major challenges confronting humanity.Superconductivity has, over the century since its discovery by Kamerlingh Onnes in 1911, promised to provide solutions to many challenges. So far, most superconducting technologies are esoteric systems that are used in laboratories and hospitals. Large science projects have long appreciated the ability of superconductivity to efficiently create high magnetic fields that are otherwise very costly to achieve with ordinary materials. The most successful applications outside of large science are high-field magnets for magnetic resonance imaging, laboratory

“…As one of the most impressive and promising applications of bulk high-temperature superconductors (HTSCs), hightemperature superconducting (HTS) Maglev vehicles [1] with outstanding advantages of high speed, comfort, environment friendliness, low maintenance and low energy consumption, have been proposed as an important choice for future transportation methods, especially for super-high speed evacuated tube transportation (ETT) [2]. In the past 25 years, this technology has greatly progressed from early models and demonstrators to present prototypes with long permanent magnet guideway (PMG) lines [3][4][5][6][7][8][9][10].…”

We report a simple, efficient and economical way to enhance the levitation or guidance performance of present high-temperature superconducting (HTS) Maglev systems by exploring the anisotropic properties of the critical current density in the a-b plane and along the c-axis of bulk superconductors. In the method, the bulk laying mode with different c-axis directions is designed to match with the magnetic field configuration of the applied permanent magnet guideway (PMG). Experimental results indicate that more than a factor of two improvement in the levitation force or guidance force is achieved when changing the laying mode of bulk superconductors from the traditional fashion of keeping the c-axis vertical to the PMG surface to the studied one of keeping the c-axis parallel to the PMG surface, at the maximum horizontal and vertical magnetic field positions of the PMG, respectively. These phenomena resulted from the physical nature of the generated levitation force and guidance force (electromagnetic forces) and the fact that there are different critical current densities in the a-b plane and along the c axis. Based on the experimental results, new HTS Maglev systems can be designed to meet the requirements of practical heavy-load or curved-route applications.
