Abstract: The electric propulsion technology has become a significant direction of electrification of aircraft power system after more/all electric aircraft gradually unifies the secondary power into electric power, and represents the advanced stage of electrification of aircraft. The electric propulsion system is expected to further improve energy conversion efficiency of traditional aircraft power plants, and as a result greatly improve fuel consumption and emission performance of aircraft. The system and related technologies are important support for the development of the electric propulsion technology. In this paper, the types and art of the state of electric propulsion aircraft are systematically summarized. The basic concepts, characteristics and significance of the hybrid power system and distributed electric propulsion system are discussed. The basic structure of the electric propulsion system is described, and the architectures of the electric power system suitable for the distributed electric propulsion system are compared. Key technologies of the electric propulsion system including high efficiency and high power density machines, high efficiency and high capacity power converters, thermal management, etc., are discussed systematically. So far, small electric aircraft are becoming more and more practical, but the distributed hybrid electric propulsion technology, which is an important direction for electrification of medium and large aircraft, still need combination and innovation of aviation electromechanical devices and power systems.

Key words: distributed electric propulsion aircraft, hybrid electric propulsion, electric power system, electric machines and power electronics, superconducting electrical technology
