抄録

The magnetic sail is a spacecraft propulsion system using the interaction between the magnetic field and the solar wind. In this paper, to evaluate the propulsive force generated by a Pure Magnetic Sail spacecraft, a new numerical analysis model including the ion's finite Larmor-radius effect is proposed. In this analysis model, the trajectories of ion particles are solved based on the Flux-Tube model and electrons are treated as a plasma fluid under the assumption of quasi-neutrality and steady state. As for the electromagnetic field, the induction equation is employed to obtain a steady electromagnetic field. Using the Flux-Tube model, a 500-km-size magnetosphere was found to produce a thrust level of 1500N when a magnetic moment of the magnetic sail is set to 3.9×10¹⁶Wbm. This thrust level agrees well with the result obtained by magnetohydrodynamics model (1600N) and that by Hybrid particle-in-cell model including ion kinetic effects (1560N). Also, the computational cost of the Flux-Tube model is reduced to about 1/10 of that of Hybrid-PIC model.
