Abstract:

利用国军标方法GJB/Z84-1996及CAD系统软件,在标准条件(pc/p0=70∶1)下计算了含5,5′-联四唑-1,1′-二氧二羟铵(TKX-50)的复合改性双基(CMDB)推进剂、端羟聚丁二烯(HTPB)推进剂、硝酸酯增塑聚醚(NEPE)推进剂及聚叠氮缩水甘油醚(GAP)推进剂的能量特性。结果表明,TKX-50单元推进剂的理论比冲为2623.7N·s·kg-1,比RDX单元推进剂的理论比冲高6.5N·s·kg-1。TKX-50是CMDB推进剂中RDX的较好替代物。当TKX-50取代HTPB推进剂中的AP和GAP推进剂中的HMX和AP时,TKX-50基HTPB推进剂和TKX-50基GAP推进剂的理论比冲均存在能量的最优值。当TKX-50取代NEPE推进剂中的AP和HMX时,TKX-50基NEPE推进剂的理论比冲先增后降再增,最大增加20.4N·s·kg-1。
