研究了LA铅盐、GT铜盐及其碳黑复合物对硝胺/叠氮推进剂燃烧性能的影响。结果表明:GT铜盐可提高叠氮/硝胺推进剂的燃速,质量分数1%的GT铜盐能提高推进剂燃速1.5～2.4 mm/s;LA铅盐、GT铜盐及其碳黑复合物可降低叠氮/硝胺推进剂压强9～19 MPa下的压强指数,推进剂中加入质量分数3%的该复合催化剂,压强9～15 MPa下推进剂压强指数由0.54降至0.47,压强15～19 MPa下压强指数由0.57降为0.41。
The effects of LA lead salt, GT copper salt and its carbon black complex on the combustion performance of nitramine / azide propellants were studied. The results show that: GT copper salt can increase the burning rate of azide / nitramine propellant; GT copper salt with mass fraction of 1% can increase the burning rate of propellant by 1.5-2.4 mm / s; LA lead salt, GT copper salt and carbon The black composite can reduce the pressure index of azide / nitramine propellant under the pressure of 9 ~ 19 MPa. When the mass fraction of the composite is 3%, the propellant pressure index decreases from 0.54 to 0.47 at the pressure of 9 ~ 15 MPa , The pressure at 15 ~ 19 MPa pressure index decreased from 0.57 to 0.41.
