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。
In order to meet the need of accurately guided weapon stealth performance, the infrared and ultraviolet characteristic signals of HTPB composite propellant were firstly tested by using the simulated rocket engine nozzle structure. Then the ferroferric oxide (HTPB) composite propellant flame was analyzed as an extinction material in the infrared band And ultraviolet radiation attenuation of the signal band. In the meantime, the influence of ferrocene extinction material on the nozzle temperature of the rocket engine was tested. The results show that the pyrotechnic formulations based on potassium nitrate, sulfur and phenolic resin provide the initial energy to promote the rapid vaporization of ferrocene and form a thin layer outside the propellant flame as a matting material, which has obvious effects on the infrared and ultraviolet bands Shading absorption, the attenuation rate can reach 50%. When the content of ferrocene is 30%, the attenuation of infrared radiation of HTPB composite propellants is the best in 710-3 500 cm-1 band. When the content of HTPB composite propellants is more than 50%, the attenuation of HTPB composite propellants is 2 400-3 500 cm-1 band infrared radiation intensity has increased.
