摘　　要：通过点火燃烧实验研究了高氯酸铵添加量对铝/冰燃料点火燃烧特性的影响.结果表明,添加高氯酸铵可促进铝/冰燃料燃烧,明显减短燃料表面引燃时间,提高燃烧最大升温速率,明显降低最快反应速率对应温度.但随高氯酸铵添加量增大,铝/冰燃料出现不稳定燃烧,升温过程中热量流失严重.未添加高氯酸铵的铝/冰燃料燃烧产物为Al_2O_3,主要呈球形颗粒,添加1%高氯酸铵的燃烧产物为Al_2O_3和nAl,主要呈絮状物,添加3%高氯酸铵的燃烧产物主要以球形颗粒并夹杂部分絮状物形式存在.The effects of proportions of ammonium perchlorate igniting and combustion experiments. The results showed that on the ignition and characteristics of aluminum/ice fuel were studied by the addition of ammonium perchlorate can promote the combustion of aluminum/ice fuel, which can shorten the ignition time of fuel surface, increase the maximum heating rate and the temperature point corresponding to the maximum reaction rate significantly shifts to the low temperature. However, with the increase of ammonium perchlorate content, aluminum/ice fuel appeared unstable combustion and the heat loss of increase. The results of SEM showed that the combustion products of aluminum/ice fuel without ammonium perchlorate was A1203, mainly contain the spherical particles. While adding 1% ammonium perchlorate, the combustion products were A1203 and nA1, mainly consist of floccules. Adding 3% ammonium perchlorate, the combustion products were mainly composed of spherical particles and some floccules.
