B–GAP对复合固体推进剂能量性能影响理论研究

Theoretical Research on Influence of B-GAP on Energy Performance of Composite Solid Propellant

提高复合固体推进剂的能量性能的方法之一,是将普通的HTPB黏合剂替换成为含能黏合剂B–GAP。利用最小自由能法,对含能黏合剂B–GAP对复合固体推进剂的能量性能影响进行了理论研究,并计算出应用B–GAP的推进剂的燃烧室平衡温度、喷管出口温度、比冲等能量性能参数,将这些性能参数与丁羟推进剂进行比较,发现均有一定程度的提高。对燃烧室压强、燃料配方对燃料能量性能的影响进行了理论研究,并与试验数据进行了对比。

One of methods for raising energy performance of composite solid propellants is that energetic B-GAP binder replaces the conventional HTPB binder. The theoretical researches on the influence of the energetic B-GAP binder on the energy performance of the composite solid propellants were carried out by using the least free energy method. The energy performance parameters of the propellants containing B-GAP such as balance temperature of combustion chamber, exit temperature of nozzle and impulse, etc. were calculated and compared with those of HTPB propellants. It is found that they all rise to a certain extent. The theoretical researches on the influence of the combustion chamber pressure, fuel formulation on fuel energy performance were carried out and compared with the experimental data.
