| 摘要: |
| 电控固体推力器具有独特的电控能力，能同时满足可重启、可控制推力且结构简单等技术要求，引起了国内外的研究关注。推进剂开发、工作机理探索、推力器结构设计和工程应用是当下研究的热点。本文总结了电控固体推力器的相关研究进展，认为装药结构失效、推进剂自持燃烧以及在大尺寸装药中难以受控燃烧等是限制其应用和发展的主要问题，从推进剂配制、推进剂制备、点火电极设计和推力控制四个方面梳理了电控固体推力器的关键技术，提出了研究建议，并结合推力器的工作特点和应用背景展望了发展趋势。 |

| Abstract: |
| 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. |
