Abstract:

为研究红外照明剂中氧化剂的成分和可燃剂的含量对红外照明剂综合性能的影响,用光学性能测试装置测试了三组配方可见光的输出和红外辐射强度.测试结果表明,对于氧化剂,KNO3单位质量的红外辐射强度EJ(26.00W·s/(sr·g))最高,但是燃烧速度(1.38mm/s)过慢,而CsNO3有助于提高燃速,因此选用两者组成混合氧化剂,最佳比例为35%KNO3+35%CsNO3,单位质量的可见光EI为98.04cd·s/g,红外辐射强度EJ为16.55W·s/(sr·g),隐身指数为0.169,燃烧速度2.73mm/s.对于可燃剂,5%Mg或Ti的燃烧速度较低,分别为3.76和3.74mm/s;Si和B有利于单位质量的红外辐射强度EJ和可见光EI的输出,分别增加了20.88%和9.07%.
