The development of a pump for a liquid cryogen with a high temperature superconductor electrical drive

This work describes the research and development of a cryogenic pump that is intended for the fuel supply of aircraft engines using advanced low temperature fuel. The basic design is that of a 4-pole reluctance motor. The rotor is constructed from soft iron and BSCCO/Ag laminated material; the latter was developed by the All-Russian Scientific Research Institute of Inorganic Materials. The motor was integrated with a centrifugal cryogenic pump for the cryogenic fuel supply system, developed by the TUPOLEV Company. The results of theoretical modelling and experimental investigations are presented.
