摘　　要：为改善诱饵剂红外辐射性能,在一种MTV型诱饵剂配方中加入乌洛托品,对其燃烧后性能进行测试分析。结果表明：加入乌洛托品之后,药剂燃烧时间延长,温度降低,由于降温作用以及乌洛托品燃烧产物的选择性辐射使得诱饵剂光谱辐射亮度比L3~5μm/L2.5~3.0μm变大;当添加量为15%时,药剂燃烧时间从2.1s延长到3.56s,燃烧的最高温度从1 707.2℃降低到1 208.1℃,L3~5μm/L2.5~3.0μm从1.88提升至2.51,所以加入乌洛托品可以改善MTV诱饵剂红外辐射性能。To improve the infrared radiation performance of the decoy, different content of methenamine was added in a kind of MTV, and the combustion performance was tested. The result showed that the reaction time of the decoy was prolonged and the combustion temperature was lowered. Since the cooling effect as well as a selective radiation, the spectral radiance ratio of L3 ~ 5μm/ L2.5 ~ 3μm was increased. When adding 15% methenamine, the burning time was prolonged from 2.1s to 3.56 s, the maximum combustion temperature was reduced from 1 707.2 to 1℃ 208.1℃, L2.5 ~ 3μm / L3 ~ 5μm was increased from 1.88 to 2.51.So a certain amount of methenamine can improve the infrared radiation property of MTV decoy.
