摘要
利用国军标方法及CAD系统软件,在标准条件(P_c/P_0=70:1)下计算了含金属氢化物的丁羟推进剂和NEPE推进剂的能量特性,并与相应的含铝(Al)推进剂做对比。结果表明:含金属氢化物如BeH_2、AlH_3、Al(BH_4)_3的丁羟推进剂在很宽的范围内都可以得到2600N·s·kg^(-1)以上较高的理论比冲值;金属燃烧剂按照对NEPE推进剂能量贡献的大小排序为:BeH_2、AlH_3、Al(BH_4)_3、B_(10)H_(14)、Al、MgH_2;降低燃气的平均相对分子质量更有利于提高含金属氢化物的NEPE推进剂的比冲。
The energy parameters of HTPB propellant and NEPE propellant containing metal hydra＇des were calculated by GJB/Z 84-96 and CAD system of propellant energy calculation under standard condition（PiP0=70 ： 1）, and compared with aluminiurn-based propellant. The results show that HTPB propellant confining metal hydride, such as Bell2, AlH3 or AI（BH4）3, has a high value of specific impulse over 2 600N-s＇kg1 in very wide scope. According to the contribution of metal incendiary agents to the energy characteristics of NEPE propellant, the sequence from higher to lower is： Bell2, A1H3, AI（BH）3, B10HI4, A1, MgH2. Reducing the average relative molecular weight of combusting gas is in more favor of increasing the specific impulse of NEPE propellant containing metal hydride.
