Abstract :
To investigate the effects of load resistance and inductance on performance of linear MHD generators, a series of tests were conducted. Explosively-driven annular tubes filled with argon gas were used as plasma generators. Permanent magnets, copper electrodes, and velocity measuring ionization pins were mounted on the walls of the plasma channel of 1 inch diameter. Load resistance was varied from 2.5 to 100 m/spl Omega/, and load inductance from 0.15 to 36 /spl mu/H. Test results showed that the generated current decreased exponentially with increasing load resistance or inductance, but the generated voltage remained almost constant within experimental errors.
