摘要
为考察金属氢化物燃料对复合推进剂能量特性的影响,基于丁羟三组元和四组元配方体系,采用最小自由能原理方法,对配方进行了化学平衡性能计算,获得了金属氢化物对标准理论比冲贡献的最优值。采用金属氢化物逐步取代真实复合推进剂配方中的铝粉,并对能量特性参数和推进剂密度进行了分析,为高能复合推进剂研制提供参考。
To study energetic characteristics of metal hydride fuel additives for composite propellant, theoretical performance of HTPB/AP/MH and HTPB/AP-RDX/MH propellant were calculated based on the principle of free-energy minimization, optimum energy characteristics values for fuel additive formulation of HTPB propellant were obtained.Energetic characteristics and density of composite propellant substituting metM hydride for aluminum were analyzed.Some suggestions were provided for high energy compos ite propellant.
