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 the ways to improve the energy performance of a composite solid propellant is to replace the conventional HTPB binder with the energy-containing binder B-GAP. Using the minimum free energy method, the energy performance of the composite B-GAP was studied theoretically, and the B-GAP propellant’s equilibrium temperature of the combustion chamber, nozzle exit temperature, ratio Red and other energy performance parameters, the performance parameters and the butyrolactam were compared and found that to some extent improve. The effect of the pressure of the combustion chamber and the fuel recipe on the energy performance of the fuel was theoretically studied and compared with the experimental data.
