Abstract

Abstract: Abstract：The development of allelectric propulsion platform, the need of different space missions and space constraints make it necessary to develop the multimode operation Hall Thruster. Based on the demand analysis of allelectric propulsion platform for propeller, we discuss the key technologies. It shows that the bottleneck problems are sufficient ionization of working medium，thermal load of thruster and plum focalization under the high specific mode. The development directions of the multimode operation Hall thruster are cathode design technology in wide scope of work condition and nest technology. These need the technical breakthrough about development of the multimode Hall thruster in continuous adjustment of work mode， high specific impulse and large total specific impulse.

Key words: Keywords：all electric propulsion, Hall thruster, high specific impulse, multimode
