摘要
建立烟火药爆燃辐射模型,讨论影响光辐射强度的参数,并对高密度烟火药爆燃光辐射效应进行实验研究.结果表明:影响烟火药爆燃辐射强度的主要参数有燃烧温度、火球半径和燃烧产物中凝聚相粒子的发射率,首次提出火球膨胀体积最大时它的辐射能力最强.Al/KClO4/黏合剂(配比为50/50/3)和Al/KClO4/黏合剂/Fe2O3(50/50/3/2)两种高密度烟火药配方爆燃后,都产生较强的可见光输出和近红外辐射,理论预测值和实验测试结果基本一致,可见光强相对误差分别为6.44%和-3.87%,近红外辐射相对误差分别为4.09%和9.43%.
The radiation model of pyrotechnic deflagration is built,the parameters affecting flash radiation intensity are discussed,and radiation effect on deflagration of high-density pyrotechnic composites is studied by experiments.The results show that the main parameters influencing radiation intensity are burning temperature,fireball volume and emissivity of condensed-phase product.When expanded volume of fireball is the largest,its radiation intensity is the strongest.As to pyrotechnic composition containing Al/KClO4 /bond（its ratio is 50/50/3） and Al/ KClO4 / bond/Fe2O3（its ratio is 50/50/3/2）,they can produce the stronger visible light and near-infrared ray along with their deflagration.The theoretical values are consistent with the experimental results.The relative errors of radiation intensity of aboved formula are 6.44% and-3.87% in visible light region,4.09% and 9.43% in near infrared band respectively.
