摘要
利用单幅照相、微热电偶测温、扫描电镜(SEM)、俄歇电子能谱(EDS)以及X射线衍射(XRD)研究了Al/AP/HTPB推进剂(P-A0)、Al/储氢合金/AP/HTPB推进剂(P-A10)和储氢合金/AP/HTPB推进剂(P-A17)的火焰结构、燃烧表面温度、熄火表面形貌、熄火表面残留元素以及熄火表面残留化合物。结果表明,相对于P-A0,P-A10和P-A17燃面上方有更加猛烈的喷射现象;P-A10和P-A17的燃面温度分别提高了5.92℃和7.45℃,凝聚相反应区域分别扩大了13.13%和47.30%;P-A17熄火表面相对平整,突起的合金团表面大部分被氧化;P-A10和P-A17熄火表面残碳量相对P-A0分别减少了15.81%和27.61%,说明储氢合金可以提高AP/HTPB推进剂有机组分在燃面处的燃烧效率;P-A0,P-A10和P-A17熄火表面Al含量依次减少,而Al2O3含量依次增多,说明储氢合金的燃烧效率高于Al。储氢合金替代Al作为燃烧剂,可以明显改善AP/HTPB推进剂的燃烧性能。
The flame structures, combustion surface temperature, quenched surface appearances, quenched surface relict elements and quenched surface relict compounds of A1/AP/HTPB propellant （P-A0）, A1/hydrogen storage alloy/AP/HTPB propellant （P-A10） and hydrogen storage alloy/AP/HT- PB propellant（P-A17） were researched by using single frame photography, W-Re micro-thermal couple, scanning electron microscope （SEM） , energy dispersive spectrum （EDS） and X-ray diffraction （XRD） methods. The results show that the combustion surface of P-A10 and P-A17 exhibits a stronger injection phenomena compared to P-A0 ; their surface temperatures are increased by 5.92 ~C and 7.45 ~C, respec- tively, and their condensed phase reaction areas are increased by 13.13% and 47.30% separately in the presence of hydrogen storage alloy; The quenched surface of P-A17 is neat relatively, and the swell sur- face of alloy group is mostly oxidized; The amount of carbon left behind on quenched surfaces of P-A10 and P-A17 is lowed by 15.81% and 27.61% separately, which proves that combustion efficiency of AP/HTPB propellant organic components on the burning surface could be promoted by hydrogen storage alloy; The amount of A1 on quenched surface changes from high to low and when the amount of Al2O3 on quenched surface changes from low to high by the order of P-A0, P-A10 and P-A17, which proves that combustion efficiency of hydrogen storage alloy is higher than A1. Combustion properties of AP/HTPB propellant could be improved when using hydrogen storage alloy as combustion agent in place of A1.
