摘要: 用CO2激光点火试验设备,对Al+KClO4点火药进行点燃性能试验.试验结果表明,随着点火热流密度的增大,点火延迟时间减小.说明点火热流密度是点火药点燃性能中非常重要的控制量.点火药密度越小点火延迟时间也越小.在点火药主组分中加入少量固态硫作为粘合剂,会使点火药的点燃性能更好.

Abstract: The ignition feature of charge A1 + KC104 is investigated experimentally with CO2 laser ignition equipment in this paper. The experimental results show that ignition delay decreased with the increase of ignition heat flux, which proves that ignition heat flux is a much important control parameter in charge ignition performances. The lower the density of the charge is, the shorter the ignition delay. Furthermore, a litter added in the composition of this charge as adhesion agent will improve the ignition performances.
