添加剂Eo对NEPE推进剂高压燃烧性能的影响

The Effects of Additive Eo on the Combustion Performances of NEPE Propellants at High Pressure

采用燃速测试、微热电偶技术、燃烧火焰结构照像等试验方法,研究了含Eo的NEPE推进剂的高压燃烧性能。结果表明,推进剂中添加Eo可改善推进剂的高压燃烧性能,含Eo的推进剂在低压下的燃速较高,在高压下的燃速较低,并且随压强的上升,燃速压强指数降低。

The effects of additive Eo on the combustion performances of NEPE propellants were studied, by burning rate testing, microthermo couple and photographing combustion flame structures. Result shows that Eo can improve the combustion performance of NEPE propellants. At low pressure Eo can increase the burning rote of the propellants and decrease the burning rote at high pressure. With the increasing of the pressure, the burning rote pressure exponent of the propellants is reduced.
