摘要
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。
An experimental investigation on the burning rates and pressure exponents of HTPB propellants with burning rate catalysts T 27 (ferrocenyl derivative),Catocene,Fe 2O 3 is carried out at high pressure in the range from 16 to 22 MPa.The results show that ferrocenyl derivatives can increase the burning rates of HTPB/AP/Al propellants and decrease their pressure exponents greatly.Fe 2O 3 has an obvious effect on the burning rates of HTPB/AP/Al popellants,but the pressure exponents are very high.The catalytic efficiency of Fe 2O 3 is higher than that of T 27 ,but lower than that of Catocene.Adding Fe 2O 3 and ferrocenyl derivative together in the propellant can increase the burning rate further and at the same time the pressure exponent is low.
