Conceive of Cryogenic Propellant Engine Superconductor Electromagnetic Pump Circulating System

To resolve the conflict between performance and cost of propellant engine,magneto hydrodynamic(MHD) generator and direct current superconducting electrical machine principles and cryogenic liquid propellant rocket engines work environment characteristics has been combined,superconducting electromagnetic pump circulating system which is different from turbopump circulating system was put forward.Operating principles and the basic structure of superconducting electromagnetic pumps and MHD power devices which was used in system was expounded;the advantages and disadvantages of systems was analysis;preliminary feasibility of superconducting electromagnetic pump pressure circulating system was studied.In the end,the development and application prospects of the superconducting electromagnetic pumps circulating system was analysis and exposition.Concluded is that as a new rocket engine circulating system,the development and application prospects of superconducting electromagnetic pump circulatory system is very broad.
