    Abstract
  • Design methods and composition of supersonic non-equilibrium ionization magnetohydrodynamic (MHD) technical experimental system were introduced; the aspirated double-throat wind tunnel operated in Mach number 3.5 flow was designed and made. The large-scale, stable and uniform plasma was obtained continuously in supersonic flow through the capacitively coupled radio-frequency (CCRF) barrier discharge, in which the ceramic plate was taken as the barrier dielectric. Main conclusions are made as follows: the stable working time of the wind tunnel and the static pressure of experimental section are approximately 18s and 650Pa, respectively. Besides, when tunnel works in typical conditions of CCRF discharge, the conductivity of plasma is estimated to be 1.27×10-3S/m in supersonic air.
