摘　　要：基于微机电系统(MEMS)技术的固体化学微推进器阵列具有结构简单、无活动部件、功耗低、可靠性高等优点,可以用于微卫星的姿态调整、重力或阻力补偿及轨道变换等任务。国内外相继开展了固体化学微推进器阵列技术的研究。从结构设计、推进剂选择、键合工艺、点火电路等方面综述了各研究团队采取的技术途径和取得的进展,分析了各种技术途径的优缺点。提出了通过调整喷管结构和优化推进剂,提高微推进器的单元冲量,采用具有寻址点火特征的交叉式引线结构点火阵列,解决点火控制电路结构复杂的难题,并指出了固体化学微推进器阵列技术的发展方向。The MEMS based solid propellant microthrusters( SPM) array having the advantages of simple configuration,absence of moving parts,low energy dissipation,and high reliability,can be used as the micro propulsion system to implement altitude adjustment,gravity or drag compensation and orbital transfer. Many research groups at home or abroad have carried out research on SPM array. This review summarized technology and research advance of SPM array,including architectural design,solid propellant selection,bonding technology,layout of ignition circuit,and analysis of their merits and faults. Proposals were made on improving the thrust performance of microthruters by adjustment of nozzle structure and formula optimization of composite propellant. The ignition circuit is the prerequisite for the development of large-scale integrated SPM array.
