Interaction of the solar wind with the magnetic sail is numerically simulated by the full particle (PIC) method. Fundamental features of the flow field and the induced electromagnetic field around the small magnetic sail are clarified. Force acting upon the magnetic sail, which is estimated by considering the Lorentz force generated by the induced electromagnetic field and the momentum change of the solar wind around the magnetic sail, is in the order of 10(exp -3) mN. Additionally, optional concepts of sailing propulsion, which use applied electric field or artificial charged particles, are also considered. The new concepts may improve the acceleration performance and/or payload capacity of the sailing propulsions., 資料番号: AA0049193005, レポート番号: JAXA-RR-05-014}, title = {磁気セイルの推進力の見積もりと性能向上のためのオプション}, year = {2006} }
