摘　　要：通过差热-热重联用、扫描电镜和单幅摄影等实验手段,研究了环氧乙烷-四氢呋喃共聚醚/高氯酸铵/降温剂燃气发生剂燃烧机理,在AP复合推进剂的多火焰燃烧(BDP)模型基础上,建立了其燃气发生剂燃烧物理模型。认为燃气发生剂燃烧模型中存在四个火焰区,分别为PF焰、AP焰、PJW焰及FF焰,并运用该燃烧物理模型解释了燃烧中特殊现象(如燃速低、易熄火等)产生的原因。Combustion mechanisms of the PET/AP/JW1 gas generating propellant has been studied by experimental methods of DSC-TG, SEM and single flame photograph etc.. A combustion model of the PET-type gas generating propellant based on the BDP model has been proposed. Four types of flames： PF flame, AP flame, PJWflame and FF flame are considered. Explanation of the special phenomena （ such as low burning rate, easy self-extinguishment etc. ） during the combustion has also been given by using the combustion model.
