在以ＡＰ、ＲＤＸ、ＨＴＰＢ及添加剂含量分别为５０％，２５％，１２．５％及１２．５％的基本配方的推进剂中，再添加不同种类、不同粒度及不同份额的催化剂，用声发射法测定了４～８ＭＰａ下推进剂的燃速。实验结果表明：超微细Ｃｕ_２Ｏ（０．２μｍ）能大幅度提高推进剂的燃速，８ＭＰａ下加入２％可使燃速提高７７．１％，是市购化学纯Ｃｕ_２Ｏ（３μｍ）提高幅度的五倍多，与两种含铜催化剂──铜铬氧化物（ＹＢ）、有机铜（Ⅱ）络合物（ＱＣ）混合作用，在８ＭＰａ下可分别使燃速提高１２０％和使压强指数降低５０％。 In the propellants of AP, RDX, HTPB and the basic formula containing 50%, 25%, 12.5% ​​and 12.5% ​​of the additive respectively, catalysts of different kinds, different sizes and different proportions were added, Launch method was used to determine the burning rate of propellant at 4 ~ 8MPa. The experimental results show that ultrafine Cu_2O (0.2μm) can greatly improve the burning rate of propellant, and the addition of 2% at 8MPa can increase the burning rate by 77.1%, which is five times higher than that of pure Cu_2O (3μm) Times as many as two kinds of copper-containing catalysts ─ copper-chromium oxide (YB) and organic copper (Ⅱ) complexes (QC), can improve the burning rate by 120% and the pressure index by 50 %.
