Explosively Driven MHD Generator Power Systems for Pulse Power Applications
Explosively driven MHD generators offer one means of generating very large bursts of energy directly without the requirement for switching. Since switches for systems using conventional techniques for generating very high energy bursts are not presently available, this feature is very significant.
In an explosively driven MHD generator, a high enthalpy plasma is generated by detonating an explosive charge in a containment chamber; this plasma as it is formed is directed toward the channel and expanded at the same time. As the plasma moves through the generator channel cutting a magnetic field at very high speeds, it generates a high energy pulse. This paper reports the results of a preliminary investigation of explosively driven MHD generators. The work performed was both of an analytical and experimental nature including studies of explosives, detonators, expansion of detonation products and evaluation of conductivity of expanded gases resulting from detonation of explosive charges. The results of this work provides a sound foundation for continuing explosively driven MHD generator research and development programs.
