摘　　要：传统镁/聚四氟乙烯(Mg/PTFE)红外诱饵剂被广泛应用于对抗红外制导武器,但随着红外制导技术发展,其长波红外辐射不足、燃烧温度过高等缺点令其难以对抗新型红外制导弹药.针对这一问题,提出了采用硅酸锆(ZrSiO_(4))作为添加剂来提高传统诱饵剂红外辐射的方法.以四氧化三铅/镁粉/聚四氟乙烯(Pb_(3)O_(4)/Mg/PTFE)红外诱饵剂作为基础配方,设计了7种配方,通过实验研究了不同ZrSiO_(4)添加量对Pb_(3)O_(4)/Mg/PTFE红外诱饵剂效能的影响.首先测试了基础配方(ZrSiO_(4)添加量为0)和12%ZrSiO_(4)添加量配方的热分解性能,然后用7.5—14μm远红外热像仪测量了压制成药柱样品的燃烧过程,并计算出每个样品的燃烧时间、燃烧温度、质量燃速、辐射面积、远红外辐射亮度和辐射强度.结果表明:添加ZrSiO_(4)后,混合红外诱饵剂反应放热峰值减小,热效应变差;随着ZrSiO_(4)添加量增大,样品燃烧时间持续变长,燃烧温度持续降低.当ZrSiO_(4)添加比例为18%时,样品反应时间最长达3.73 s,燃烧温度最低达765.46℃;远红外辐射亮度和辐射强度均随着ZrSiO_(4)添加比例升高先增大后减小,且当ZrSiO_(4)添加比例为6%时分别达到最大值2461 W/(m^(2)·sr)和142 W/sr;当ZrSiO_(4)添加比例在18%以内和9%以内时分别对基础配方的远红外辐射亮度和辐射强度有提升作用.Traditional composite infrared decoy,magnesium/teflon(Mg/PTFE),has been widely used in countering infrared guided weapons since its advent.However,with the development of infrared guidance technology,its drawbacks such as insufficient far-infrared radiation and high combustion temperature emerge,making it difficult to counter novel infrared guided weapons.To address this issue,a strategy of utilizing zirconium silicate(ZrSiO_(4))as an additive is proposed to improve the infrared radiation of infrared decoy.Therein,seven formulations with different ratios of ZrSiO_(4)are designed based on the basic formula of trilead tetraoxide/magnesium/teflon(Pb_(3)O_(4)/Mg/PTFE)mixed powder.And the effect of ZrSiO_(4)serving as an additive on the performance of Pb_(3)O_(4)/Mg/PTFE infrared decoy is analyzed through experiments.First,initial experiments are conducted on the thermal decomposition characteristics of the basic formula(ZrSiO_(4)addition ratio is 0%)and its variant counterpart with 12%ZrSiO_(4).Subsequently,the combustion behaviors of the compacted formulation samples are examined using an infrared thermal imager operating within the 7.5-14μm range,subsequently,the combution time,combution temperature,burning rate,radiation area,radiance,and radiation intensity of individual samples are computed.These results show that incorporation of ZrSiO_(4)reduces the intensity of the primary exothermic peak during the reactions with a mixed infrared decoy agent,yielding suboptimal thermal efficiencies.Furthermore,the combustion durations of the samples progressively increase with ZrSiO_(4)addition increasing,accompanied by consistent reductions in their combustion temperatures.Specifically,the sample reaction time peaks at 3.73 s at a ZrSiO_(4)addition ratio of 18%,while the combution temperature drops to a minimum value of 765.46℃.Moreover,the far-infrared radiance and radiation intensity demonstrate an initialincrease-then-decrease trend with ZrSiO_(4)addition increasing,thereby achieving the maximum values of 2461 W/(m^(2
