Abstract

Magnetic plasma sails have possibilities to reduce drastically mission durations of deep space explorations by using the momentum of the solar wind to produce its thrust. In order to produce a practical magnitude of the thrust, the magnetic plasma sails are required to inflate applied magnetic fields by injecting plasma from the spacecrafts. In this study, the magnetic field inflation by the plasma injection is numerically simulated by one component plasma model, which can be performed more robustly than those by hybrid simulations. The fundamental features of the injected plasma flow field and the electromagnetic field around the magnetic plasma sail are investigated, especially on the effects of the direction and the density of the plasma injection. The magnetic field can be inflated by the plasma injection in the one component plasma model. The direction and density of the plasma injection have strong impacts on the flow field and magnetic field inflation.
