Abstract : An experimental study was performed of the operating characteristics of a large linear, supersonic MHD generator. A shock tunnel was used to heat the test gases, which was primarily a 99 percent neon+1 percent xenon mixture, to stagnation pressures of 1 to 5 atmospheres, temperatures of about 3500K, and electron densities on the order of 10 to the 10th power /cc. The test time of 5 milliseconds, which was about 10 times the traversal time of the gas through the generator, was sufficient to produce quasi-steady state conditions in the channel. It was concluded that electrode conduction losses and shock wave formations were the two major factors limiting the efficiency of this generator. (Author)
