Abstract: In order to investigate the effects of the aluminum particles on the combustion performance of HTPB-based fuels for hybrid propellant, a transparent combustion chamber experimental system was used in this study. HTPB-based fuel containing different particle size (average size is 100nm, 500nm and 50μm) and different mass fraction (5wt%, 10wt% and 15wt%) of aluminum particle respectively were tested and analyzed. The curves of regression rate vs. oxygen mass flux for HTPB-based fuel containing aluminum particles were obtained under the combustion chamber pressure of 1.0MPa. The results showed that the regression rate of HTPB-based fuel containing aluminum particles increased with the increase of the oxygen mass flux. The regression rate of HTPB-based fuel containing 5wt% 500nm aluminum particles was higher than that of HTPB-based fuel containing 5wt% 100nm and 50μm aluminum particles under oxygen flux 250 ~ 375kg/(m2·s). The regression rate of HTPB-based fuel containing 500nm aluminum particles increased with the increase of aluminum particle content.

摘要: 为了研究铝粒子对HTPB固液混合推进燃料退移速率的影响,采用透明燃烧室实验系统,开展了含不同粒径(平均粒径分别为100nm,500nm和50μm)、不同质量分数(5wt%,10wt%和15wt%)的铝粒子HTPB燃料退移速率测试和分析,获取了燃烧室压力为1MPa下的含铝HTPB燃料的瞬时退移速率随氧气质量密流变化的曲线。研究结果表明,随着氧气质量密流的增加,含铝HTPB燃料的退移速率增加;当氧气质量密流为250 ~ 375 kg/(m2·s)和铝粒子含量为5wt %时,平均粒径为500nm比平均粒径为100nm和50μm的含铝HTPB燃料退移速率高;当铝粒子平均粒径为500nm时,含铝HTPB燃料的退移速率随着铝粒子含量的增加而增加。
