摘要
采用固体发动机装药排气羽烟激光测试系统,测试了某激光制导导弹装药排气羽烟的激光透过率。分析了点火药、包覆层、推进剂对装药激光透过率的影响。结果表明,用黑火药作点火药时,少量的黑火药对排气激光透过率有明显的影响;采用醋酸纤维素包覆层的装药排气激光透过率较低。指出了在包覆层配方设计时,应选择氮、氧含量较高的聚氨酯高聚物基体,加入N、O含量高的有机填料,以减少包覆层在推进剂燃烧时的烟雾,从而提高装药的激光透过率。当推进剂配方中不含铝、镁等金属添加剂时,添加少量、高效的催化剂以及低分子量、高含氧量的增塑剂,可以提高装药的激光透过率。
A plume laser detecting system for solid propellant charge was used to detect the laser transmittance of the laser guided missile charge. Influences of igniting powder, inhibitor and propellant on the laser transmittance of the propellant charge were analyzed, It was found that a small amount of black powder, used as amorce, can obviously affect the laser transmittance of the propellant charge exhaust. The propellant charge by applying cellulose acetate as inhibitor has lower laser transmittance. The laser transmittance of the propellant charge was increased by addition of the organic materials with high content of nitrogen and oxygen in the inhibitor polymers, containing abundant nitrogen and oxygen. The high efficient catalyst, low molecular mass plasticizer with high oxygen content, and without addition of metal fuels such as aluminium and magnesium in propellant have positive effects on increasing the laser transmittance of the propellant charge.
