摘要
为研究1.06μm、3.5μm、10.6μm三波长激光所受导弹推进剂尾烟干扰的差异程度,建立开放式烟道测试系统。在烟道头部放置装填有典型导弹推进剂的缩比发动机,点燃推进剂使之喷射并形成烟柱,在烟道尾部烟柱直径方向设置激光发射和接收装置,用以获取3波长的透过率。试验数据分析表明,烟雾对激光的衰减与烟雾粒子半径有关,在400m烟道长度环境中,10.6μm激光透过率最高可达1.06μm激光的104倍。该结果有益于激光制导武器的改进和升级。
In order to study the degree of discrepancy for 1.06 μm/3.5μm/10.6μm three-wave- length laser attenuation due to the missile tail smoke, we established the opening smoke channel test platform. The shrink ratio engines filled up by 3 different kinds of propellant were planted at the head of the smoke channel, and the plume were formed while engines worked. The multi-wavelength laser emitter and receiver were placed by the side of smoke channel along the diameter direction, so as to obtain the multi-wavelength laser transmittance . The results show that the laser attenuation effected by smoke was related to the particle radius of smoke, and in the 400 m smoke channel environment, the maxim transmittance of 10.6 μm laser is 104 higher than that of 1.06μm laser. These results are benefit to the improvement and upgrading of laser guiding weapon system.
