Magnetohydrodynamic Analysis of Magnetoplasma Sail for Plasma Injection Angle considering Thermal Pressure and Dynamic Pressure

Yuki Murayama Ryota Hara Yoshiki Yamagiwa Yuya Oshio Hiroyuki Nishida Ikkoh Funaki

Journal of Evolving Space Activities 71(2) 67-77 Mar 2024 [Refereed]

Magsail is a space propulsion system using the interactions between the solar wind and the magnetic field generated by the onboard coils. Magnetoplasma sail is a propulsion system that increases thrust by expanding the magnetosphere through plasma...
