Stability of an open-cycle supersonic disk MHD generator is studied, and effects of load conditions on stabilizing the generator are investigated. The spatial growth rate of inlet disturbances during the propagation is evaluated by means of a sensitivity analysis, which shows that the generator is very sensitive under the constant current load condition. A method of linear stability analysis is proposed for supersonic disk MHD generator considering their load conditions in order to analyze instability induced by load current disturbances. The linear analyses and time-dependent calculations show that constant load voltage operation with multiple-loading scheme is effective to suppress instability and high sensitivity, and that series inductors do not always stabilize the generator.
