The theory and experimental performance of the thermionic converter is analyzed for use in power conversion in a nuclear-electric space propulsion system. Electrical propulsion power requirements are shown to demand a minimum ratio of powerplant weight to power in the jet. The elements of a powerplant into which the converter must be integrated are discussed, including compatible nuclear reactor design, radiator, and electrical acceleration devices. The basic theory of the vacuum and cesium converter is presented with special emphasis on efficiency, power output, and lifetime. Theoretical and experimental analyses of the ability of the thermionic converter to provide a low powerplant weight indicated the system concept compares favorably with turbogenerator conversion.
