Feasibility Analysis of Helical Superconducting MHD Propulsor for Vessel Propulsion

In this paper, a MHD propulsor model for design and optimization is built. And it is used to achieve the most efficient propulsor with the given warm bore diameter and field strength, then these two constraint parameters are scanned within the range of 0.1~1 m, 1~20 Tesla. Based on the result above and current status of magnet technology, we can infer that it is very difficult for MHD propulsor to be used practically.
