The superconducting machine has prospects of a wide range of applications in aviation electric propulsion due to its advantages such as small size, high power density, and high efficiency. The characteristics and current situation of the superconducting pure/hybrid electric drive systems are compared, showing the importance of the superconducting machine for high power aviation electric propulsion. In view of different requirements for motors and generators for the superconducting electric drive system for high power aviation electric propulsion, the operating principles and structural topologies of those prototypes of High Temperature Superconducting (HTS) machines studied in the past are reviewed and classified, and the advantages and disadvantages are summarized and analyzed. On this basis, the key technologies of superconducting machine are outlined in terms of superconducting technology, AC superconducting armature, rotor technology, cryogenic technology and insulation technology. Under the background of aviation electrification, the progress in the application of superconducting electric drive system in aviation electric propulsion is outlined, and future development of superconducting electric aviation is also discussed.
