对含Ｔ２７（一种二茂铁衍生物）、卡托辛、Ｆｅ２Ｏ３三种燃速催化剂的ＨＴＰＢ／ＡＰ／Ａｌ推进剂在１６ＭＰａ～２２ＭＰａ下的燃速和燃速压强指数进行了研究。结果表明：二茂铁衍生物能大幅度提高ＨＴＰＢ／ＡＰ／Ａｌ推进剂的燃速，同时可使高压下的压强指数大幅度地下降；Ｆｅ２Ｏ３对ＨＴＰＢ／ＡＰ／Ａｌ推进剂有着显著的燃速催化效果，但其推进剂压强指数较高；Ｆｅ２Ｏ３的催化效率较Ｔ２７高，但不及卡托辛；Ｆｅ２Ｏ３和二茂铁衍生物组合使用能进一步提高ＨＴＰＢ／ＡＰ／Ａｌ推进剂的燃速，并使推进剂具有较低的压强指数。
The burning rate and burning rate pressure exponent of HTPB / AP / Al propellants containing T27 (a ferrocene derivative), catokin and Fe2O3 three burning rate catalysts were studied at 16MPa ~ 22MPa. The results show that the ferrocene derivatives can greatly improve the burning rate of HTPB / AP / Al propellants and at the same time can significantly reduce the pressure exponent under high pressure. Fe2O3 has a significant burning rate for HTPB / AP / Al propellants Catalytic effect, but its propellant pressure index is higher; the catalytic efficiency of Fe2O3 is higher than that of T27, but less than that of catolcine; the combination of Fe2O3 and ferrocene derivatives can further increase the burning rate of HTPB / AP / Al propellants The propellant has a lower pressure index.
