Recent results of our quasi-one-dimensional numerical simulation for the performance of an MHD accelerator under chemical and thermal equilibrium conditions are presented. For the present study, the working gas was changed to air-plasma from inert gas of argon plasma, which was studied previously to actualize the application of an MHD accelerator propulsion system. The numerical simulation confirmed the performance of MHD accelerators with segmented Faraday, Hall, and diagonal electrode connections. In order to solve the set of differential equations of magnetohydrodynamics, the MacCormack scheme is employed. The results show several parameters of MHD accelerator performance with air-plasma working gas. The calculation results are compared with previous results to clarify the effect of the difference in working gases.
