摘要:
为研究新型燃烧催化剂复合有机酸铅(Mu-Pb)对改性双基(CMDB)推进剂的热分解和燃烧性能的影响,通过靶线法分析了添加Mu-Pb的HMX/Al-CMDB推进剂的热分解和燃烧特性;同时,采用差示量热扫描仪(DSC)进一步研究了Mu-Pb对CMDB推进剂及硝化棉(NC)/硝化甘油(NG)、奥克托今(HMX)热分解行为的影响。结果表明,一定压力区间内,随着Mu-Pb含量的增加,CMDB推进剂燃速有所升高,燃速压强指数n有降低趋势。当Mu-Pb质量分数由2%增加至4%时,10 MPa下CMDB推进剂的燃速提高了15%,且10~22 MPa时的n由0.67降低至0.40。Mu-Pb对CMDB推进剂热分解的两个阶段均有催化作用,因而可以提高推进剂的中、低压燃速,且其对第2阶段HMX的热分解促进作用更为显著,可以使HMX的热分解表观活化能Ea降低近70%,而对第1阶段NC/NG的Ea影响相对较小。
