摘　　要：为了抑制固体火箭发动机羽流的二次燃烧,最好的方法是在推进剂配方中添加钾盐作为抑制剂。介绍了无机钾盐如KNO_(3)、K_(2)SO_(4)、K_(3)AlF_(6)、KA、含能硝基配合物、含能亚硝酸复合钾盐KE和有机钾盐KD等对固体推进剂的分解动力学、羽流电子密度、火焰结构和温度、燃烧速率、燃烧波结构、熄火表面及平台燃烧效应的影响。还介绍了一些新型有机含能与不含能的钾盐。对目前固体推进剂消焰剂的研究中存在的问题及未来发展方向进行了展望,可为相关领域的研究提供借鉴。In order to suppress the secondary combustion of the solid rocket engine plume,the best method is to use potassium salt as an inhibitor in the propellant formulation.This review discussed and summarized the influence of a great number of potassium salts including inorganic(KNO_(3),K_(2)SO_(4),K_(3)AlF_(6),KA,KE,LiF and energetic nitro complexes)and organic(organic potassium salts KD and MOFs)compounds on the decomposition kinetics,flame structures and temperature,burning rate,combustion wave structures,quenched surface of solid propellants,especially the plateau burning effect.Some new organic energy-containing and non-energy-containing potassium salts were also introduced.The problems existing in the current research on solid propellant flame suppressants and the possible future development directions were discussed,which can provide reference for the research in related fields.
