含5,5'-联四唑-1,1'-二氧二羟铵推进剂的能量特性计算

Energetic Characteristics Computation of Propellants Containing Dihydroxylammonium 5,5'-Bistetrazole-1,1'-diolate(TKX-50)

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。

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 dihydroxylammonium5,5＇-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- 1 and 6. 5 N·s·kg- 1 higher 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.
