摘　　要：为了准确评价推进剂的羽烟水平,采用美军SCF(SignatureCharacterizationFacility)烟箱法的原理,研制了推进剂环境实验箱以及可见光、近、中、远红外透过率测试系统。利用该系统进行了透过率测试,系统测试精度小于3%。制定了羽烟光学透过率测试标准,据此对不同配方的推进剂一次烟、二次烟进行了研究,结果表明,一次烟的光学透过率随铝粉含量增加而降低,而二次烟的光学透过率主要与AP含量密切相关,产生几率与环境温湿度有关。A signal (including visible light, near-mid-far infrared radiation) transmittance measuring system and a smoke-box were studied and established to evaluate the signature of solid propellant formulation base on the framework of SCF (Signature Characterization Facility).In order to validate this system, a number of tests performed by adopting different propellant formulations under different experimental conditions. The result shows that the testing accuracy of the system is less than 3%. Based on the experimental data, a standard to characterize the signals transmittance of primary and secondary smoke has been established. The results indicate that the signal transmittance decreases with increasing the content of Al powder for primary smoke and closely relates to the content of AP in propellant formulation for secondary smoke, and the occurrence of secondary smoke is related to the temperature and humidity in the smoke -box.
