Abstract:

为提高KNO3/Mg-Al红外诱饵剂红外辐射强度,采用药剂中添加硼(B)粉的方法,借助远红外热像仪对诱饵剂燃烧及红外辐射特性进行了实验研究。结果表明,添加B粉后诱饵剂的质量燃速、燃烧温度、辐射亮度增大。当B粉含量由0%增加到2%时,诱饵剂的质量燃速从0.394 g·s-1提高到0.564 g·s-1。当B粉含量由0%增加到4%时,燃烧温度和辐射亮度分别从727.71 ℃、995.68 W·m-2·sr-1增加到1046.19 ℃、1681.59 W·m-2·sr-1。辐射强度随B粉含量增加呈现出先增加后减小的趋势,B粉含量为4%时辐射强度达到极值2.64 W·sr-1,显示一定比例B粉可有效提高诱饵剂的质量燃速、燃烧温度及红外辐射特性
