摘　　要：对固体火箭发动机不稳定燃烧的国内外研究现状和进展进行了详细综述.分别从物理概念、理论预估模型、实验研究、数值模拟等方面出发,论述了不稳定燃烧研究过程中的难点和一些经验教训.提出了应加强流场与声场能量交换、铝粉综合作用等机理的理论研究;开展分布燃烧、脉冲触发不稳定燃烧的实验研究;进一步开发稳定性预估软件等观点,为国内固体火箭发动机在该领域的研究提供参考.The present situation and progress of investigation on combustion instability of solid rocket motors were introduced both at home and abroad in details.This paper attempts to organize these theories and lessons by detail physical concepts,prediction models,experimental methods and numerical simulations.The following viewpoints are proposed：（1） theoretical studies on energy transport mechanism between flow field and acoustic field,as well as the complex effect of aluminum,shall be emphasized;（2） experimental faculties for distributed combustion and pulsing triggering instability shall be established;（3） stability prediction program shall be developed.The analysis could provide a reference for research on combustion instability of solid rocket motors.
