摘要：
The electronically controlled solid thruster has a unique electric control capability and satisfies the technical requirements such as restartable，controllable thrust and simple structure，which has been attracting the attention of domestic and foreign research institutions. Propellant development，working mechanism exploration，thruster structure design and engineering applications are the hot spots of current research. The relevant research progress of electronically controlled solid thrusters have been summarized. The problems of grain structure failure，propellant self-sustaining combustion and the difficulty of controlled combustion in large size grains were identified as the main problems limiting their application and development. The key technologies of electronically controlled solid thruster are summarized and sorted out from four aspects：propellant formulation，propellant preparation，ignition electrode design and thrust control，the research suggestions are put forward，and the development trend is looked forward with the working characteristics and application background of this thruster. © 2023 Journal of Propulsion Technology.
