Virtual Bookstore Citation Title ELECTROMAGNETIC ALKALI METAL PUMP RESEARCH PROGRAM Author(s) Verkamp, J. P.; Rhudy, R. G. Corporate Author(s) GENERAL ELECTRIC CO CINCINNATI OH Report Date 2/1/1966 Page Count 246 Abstract A study program, initiated by NASA, to select EM pumps for six applications in space power systems using alkali metal coolants and working fluids, is described. Applications to both turboelectric and thermionic systems are considered for potassium, lithium, and NaK up to 2000 deg F. The study covers flow rates to 3300 gum and developed heads to 100 psi. Results indicate that a tenfold improvement over the weights of conventional EM pumps is attainable. All basic pump types, plus the significant variants of each, are described relative to operating principles, general configurations, performance features, reliability, and advantages and disadvantages. Design considerations are developed mathematically and are presented graphically. Five different kinds of pumps are selected for detailed study. For these, conceptual designs, calculations, and performance prediction methods are presented. Preliminary designs are shown for pumps satisfying the six specific applications. All materials selected are within present technology. Pump weights, efficiencies, and other power plant application data are determined. Also considered are power supply, power conditioning, and heat dissipation. Other conclusions reached during the study are discussed.
