A seed-free radio-frequency (RF) pre-ionized inert gas plasma MHD electrical power generation has been firstly demonstrated in fundamental experiments with a shock-tunnel facility. An enthalpy extraction ratio of 2.6% was successfully obtained even under an inlet total temperature of 2200K at which the power generation can be operated continuously. Since the RF input power required for the pre-ionization tends to be increased for lower inlet total temperature, the reduction of the RF input power is needed for further improvement in the total performance.
