    摘要:

    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2623.7 N·s·kg-1, 比RDX单元推进剂的理论比冲高6.5 N·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20.4 N·s·kg-1

    Abstract:

    Energy characteristics of the composite modified double-base (CMDB) propellant, hydroxy terminated polybutadiene(HTPB)propellant, nitrate ester plasticized polyether (NEPE) propellant and glycidyl azide polymer (GAP) propellant containing dihydroxylammonium 5, 5′-bistetrazole-1, 1′-diolate(TKX-50) were calculated by CAD system software according to military standard GJB/Z84-1996 under the standard condition(pc/p0=70:1). Results show that theoretical specific impulse of the TKX-50 monopropellant is 2623.7 N·s·kg-1and 6.5 N·s·kg-1higher than that of the RDX monopropellant. TKX-50 is a better replacement of RDX in CMDB propellant. When the substitution of TKX-50 for AP in HTPB propellant and AP and HMX in GAP propellant, theoretical specific impulses for TKX-50-based HTPB propellant and TKX-50-based GAP propellant exist a optimal value of energy. When the substitution of TKX-50 for AP and HMX in NEPE propellant, theoretical specific impulse of TKX-50-based NEPE propellant increases at first, then decreases, and then increases, and the maximum increase can reach 20.4 N·s·kg-1.
