摘 要:运用红外热成像仪分别在烟箱和外场研究了铜粉烟幕对3~5μm红外波段的遮蔽效果,并计算了消光系数。研究表明铜粉发烟剂对3~5μm中红外波段有良好的消光性能。在20 m3烟箱中施放20 g铜粉发烟剂有效遮蔽时间在3 min以上;相同质量浓度的烟幕在外场红外有效干扰时间在30 s以上。本研究为该类烟幕的实际应用提供了参考。The anti-3-5 μm infrared performance of smoke based on copper power has been tested and studied within a smoke chamber and on outfield with a thermal imager respectively, and the light extinction coefficient has been calculated. The result showed that smoke agent based on copper powder has an excellent 3-5 μm infrared extinction performance. An amount of 20 g copper powder was insuffiated into a 20 m^3 smoke chamber, the infrared image of drone could not be observed more than 3 min, and efficient Interfering IR time of the same mass consistency smoke on outfield is more than 30 s. The research will provide reference for effective application of this type of smoke.
