| 摘 要： | 为了研究高速降压对底排装置工作稳定性的影响,采用模拟实验装置和高速录像系统,对复合底排药剂(AP/HTPB)瞬态降压下的燃烧行为进行了系统研究.实验表明:复合底排药剂在瞬态扰动下的燃烧行为分为:二次点火复燃、振荡燃烧和永久熄灭3种情况.决定这些行为特性的核心因素是降压前的初始压力和降压速率.应用非稳态燃烧理论,推导了底排瞬变燃烧条件下燃气流动特征时间计算公式.

| Abstract: | To study the combustion stability of base bleed unit under rapid depressurization,a simulating test equipment and a high-speed digital video recorder are used in the systematic researches of combustion of composite base bleed charge(AP/HTPB) under instantaneous depressurization.The results show that the instantaneous combustion can be classified into three categories,i.e.reignition,oscillation combustion,and irreversible extinguishment.The initial pressure and the depressurization velocity are the core fact... |
