In the field of aerospace propulsion, in order to further improve the comprehensive performance of existing propulsion systems and develop new high-performance propulsion systems, chemical energy is stored and converted into propulsive kinetic energy in the form of electrical energy through magnetic confinement and magnetic fluid power generation, etc. The goal of optimizing the energy distribution of the propulsion system. At present, a number of new propulsion system solutions based on electromagnetic assist mechanisms have been proposed at home and abroad, in which superconducting magnets play a key magnetic constraint and realize the role of energy conversion.
