Abstract
A new YBCO superconducting linear propulsion system that uses the Meissner effect for thrust is proposed. An YBCO bulk is used in the vehicle, which is excited synchronous with a magnetic field traveling wave. The propulsion system’s model is developed using a magnetic circuit method and the Maxwell stress tensor analysis. The vehicle acceleration and thrust force characteristics previewed from that model are verified and analyzed by practical measurements and a set of essays using the prototype built in our laboratory. Major errors came for thermally activated flux creep and current conduction in the YBCO during its passage through the excitation system. The total magnetic field at superconductor’s surface decreases, reducing thrust force. Despite these secondary effects, results achieved show the potential of this new approach for future electric propulsion systems.
