Research on electromagnetic propulsion system based on reusable space vehicle

It is inefficient and uneconomical to complete space launch mission with the assistance of unusable rockets which is the typically used approach today, and finding a more economical way has been the pursuit of scholars all over the world. According to the purpose above, this paper proposed a new design to lift a payload to the desired orbit. In this design, the electromagnetic propulsion system (EMPS) is applied to replace the first rocket, leaving the usable rocket to take care of the rest job. Based on this design, the structure of the propulsion system is constructed and the electromagnetic properties are analyzed by finite element analysis tool Maxwell, then the mathematic model of EMPS is simulated and calculated. The result shows that EMPS is capable of accelerating the vehicle, which weighs hundreds of tons, up to one hundred meters per second. Therefore, it is foreseeable that EMPS has a certain potential in the future space launch mission.
