【摘要】 为提高典型MTV诱饵剂在3⁵μm、8¹4μm波段的红外辐射亮度,采用固相烧结法制备Mn Fe2O4型红外陶瓷,将其添加到典型MTV诱饵剂中,并对其燃烧火焰的辐射特性进行研究。结果表明:当添加25%的红外陶瓷时,在2.5³.0μm峰值辐射亮度降低了9.63×104W·m^-2·sr^-1,在3⁵μm峰值辐射亮度提高了4.05×104W·m^-2·sr^-1,在8¹4μm峰值辐射亮度提高了0.46×104W·m^-2·sr^-1,同时,辐射面积增加了74.34cm²。更多还原

【Abstract】 In order to improve the infrared radiation of the typical MTV decoy material in 3⁵μm and 8¹4μm, the Mn Fe₂O₄ infrared ceramic was prepared by solid phase sintering and added into the decoy, as well as the infrared radiation characteristic of the combustion flame was investigated. The results show that, when adding 25% of the infrared ceramic, the peak radiation brightness in 2.5³.0μm was decreased 9.63×104W·m^-2·sr^-1, but in 3⁵μm, the peak radiation brightness was increased 4.05×104W·m^-2·sr^-1, and in 8¹4μm, the peak radiation brightness was increased 0.46×104W·m^-2·sr^-1. At the same time, the radiating surface area was increased 74.34cm².更多还原
