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 effect of adding ammonium perchlorate on the ignition and combustion characteristics of aluminum / ice fuel was studied by means of ignition and combustion experiments. The results showed that the addition of ammonium perchlorate could promote the combustion of aluminum / ice fuel, significantly shorten the ignition time of the fuel surface and improve the combustion The maximum heating rate significantly decreased the temperature corresponding to the fastest reaction rate, but with the addition of ammonium perchlorate, the aluminum / ice fuel was unstable, and the heat loss was serious during the heating.Aluminum / ice without ammonium perchlorate The combustion products of the fuel were Al 2 O 3, mainly spherical particles. The combustion products of 1% ammonium perchlorate were Al 2 O 3 and n Al, mainly in the form of flocs. The combustion products with 3% ammonium perchlorate added mainly spherical particles and intercalated partial flocs Form exists.
