 note = {A series of numerical simulations of electromagnetic interaction between the solar wind and the moderately-sized magnetic sails is conducted to clarify the characteristics of reaction forces on the magnetic sail when its characteristic scale is reduced below the continuum limit at which the MHD approximations of the plasma flow fail. The hybrid particle-in-cell (PIC) method is used to take into account the non-continuum effects of the electromagnetic interactions between the flow and the magnetic field. The magnetic dipole intensity was changed so that the characteristic size of the magnetic sail changes from several hundred meters to few thousand kilometers. The results show that the drag coefficient of the magnetic sail even increases as the ratio of the ion Larmor radius to the characteristic scale of the magnetic field becomes greater than unity. This suggests that the moderately-sized magnetic sails, which are more realistic than conventional gigantic magnetic sails of several thousand kilometers from an engineering standpoint, can be one of the candidates of propulsion system for deep space missions., 資料番号: AA0048089004},
