要約(英語): In this study, the thrust efficiency of a diagonal-type pulsed MHD accelerator has been evaluated. The diagonal-type pulsed MHD accelerator consists of a model rocket engine, an external electromagnet, and a pulse-forming network. The incremental thrust was measured using a pressure sensor. To measure the specific impulse, the exhaust gas velocity was measured using an optical Time-of-Flight method. Thrust efficiency as a function of applied magnetic flux density was estimated from the incremental thrust and the specific impulse. Experimental results showed that the maximum incremental thrust was obtained at the magnetic flux density of 0.5 T. The dependence of magnetic flux density on maximum incremental thrust of the present MHD accelerator is similar to the steady-state model. It is concluded that the diagonal-type pulsed MHD accelerator can be designed by the model of conventional diagonal-type MHD accelerator.
