SUPERCONDUCTING MAGNET RESEARCH AND APPLICATION TO MHD POWER GENERATORS.
Abstract
A theoretical study of the application of large superconducting magnets to MHD generators used for space power generation is presented. The study determines the need for superconducting magnets in lieu of conventional magnets for this application. A suitable superconducting magnet MHD generator system is developed which includes the solution of the following problems: winding configuration, field strength and field varia tions, stress and magnetic force support struc tures, heat rejection radiators, cryogenic and high temperature cooling, stored helium cooling, refrigeration and insulation, superconductor properties, magnet protection, and losses in the MHD process due to field strength and field var iations. Optimum techniques and parameters are investigated for all components. This subsystem is then combined with state-of-the-art estimates of specific weights for developed turbine gener ator systems. These estimates give a final plant specific weight for a one megawatt electrical generator, operating on a Rankine cycle and uti lizing zinc as the working fluid. This system is then optimized with respect to magnetic field strength and field homogeniety. (Author)
