中文摘要：

针对精确制导武器隐身性能的需要,首先利用模拟的火箭发动机喷口结构测试了HTPB复合推进剂的红外和紫外特征信号,然后分析了二茂铁作为一种消光材料对HTPB复合推进剂火焰在红外波段和紫外波段的辐射信号衰减能力。同时,测试了二茂铁消光材料对火箭发动机的喷口温度的影响。结果表明,利用硝酸钾、硫和酚醛树脂为基础的烟火药配方提供初始能量,促使二茂铁快速汽化,并在推进剂火焰外形成薄层作为消光材料,对红外波段和紫外波段具有明显的遮蔽吸收作用,衰减率可以达到50%以上。得出二茂铁含量为30%时在710~3 500 cm-1波段,对于HTPB复合推进剂的红外辐射衰减效果最好;含量高于50%时对于HTPB复合推进剂的2 400~3 500 cm-1波段的红外辐射强度有所增加。

英文摘要：

According to the requirement of stealth performance for the precision guided weapon,infrared and ultraviolet（IR/UV） characteristic signal of the HTPB composite propellant was measured based on a simplified rocket motor,and the IR/UV extinction ability of ferrocene was compared.It was analyzed that the nozzle temperature of motor is influenced by the ferrocene.The results show that the ferrocene is converted rapidly from its solid state to its gaseous state by primary power of a pyrotechnical composite based on nitrate of potash,sulphur,and phenolic resin,and a sheet of aerosol film is formed.The aerosol film can absorb infrared and ultraviolet from the flame of propellants,and the attenuation ratio may exceed 50% in 710-3 500 cm-1 waveband when the content of ferrocene is 30%.But it will increase the infrared radiation intensity of flame of the HTPB composite propellant when the content of ferrocene exceeds 50%.
