Electromagnetic Propulsion System for Spacecraft using Geomagnetic Fields and Superconductors

This paper describes the use of different electromagnetic systems to produce a thrust force for spacecrafts in localized magnetic field. The proposed propulsion system developed in such a manner will have its own magnetic field, which will interact with the external geomagnetic field, and will be in a form of electromagnet. The force output of normal solenoids, with core, and challenges involved in thrust production are analyzed. Superconducting solenoids are considered as the viable electromagnets for the purpose. Different optimization techniques and viability of such a propulsion system in present day technology is discussed. The propulsion system developed in such a manner is comparable to present day MPD Thrusters and electric engines.
