Abstract:

Work during the past year has been focused on two distinct areas. Interest in the production of intense, short duration pulses of electric energy prompted investigation of a self-excited MHD generator capable of doing this job. Feasibility of the concept was established and design of the first test channel completed. Some experiments were also conducted on the non-equilibrium closed cycle MHD generator, which in 1974 achieved a record enthalpy extraction of 19.3. The emphasis was on reducing stagnation temperature from 3520 K where the record was achieved to the 2000 K level, which is compatible with available energy sources. Both the shock tunnel and the MHD generator become more difficult to operate as temperature drops, but results are encouraging. Author
