摘　　要：为了探讨微孔型无烟烟花发射药替代黑火药应用于地面礼花发射装药的可能性,研究了装药结构和装药条件对初速等发射效果的影响。分别改变装药量、发射药种类以及支撑环高度等装药条件,测试发射初速的变化规律,并通过光度计、声级计及激光透过率测试系统测定并对比了黑火药与无烟发射药装药的火焰强度、声响以及烟雾浓度等参数。结果表明:在发射筒内增加支撑环,可以解决发射残药的问题;随着装药量的增加、发射药传火速度提高及发射药粒径减小,弹头的发射初速逐步提高;微孔型无烟烟花发射药装药的声响同黑火药装药相近;采用微孔型无烟烟花发射药装药时发射筒口的火焰光强度、相对烟雾浓度远比黑火药装药低。微孔型无烟烟花发射药替代黑火药应用于地面礼花的发射装药是基本可行的。In order to probe into the possibility that the micropores smokeless propellant for fireworks can be substituted for black powder on ground level fireworks,the influences of the charging structures and charging conditions on bullet initial velocity and other launching effects are studied.The bullet initial velocity is tested by changing the charging mass,propellant variety and the height of support rings.The data of muzzle flash illuminance level,the sound level and the relative smog concentration are measured by photometers,sound level meters and laser smog test systems.The conclusions are as follows：the problem of propellant residue can be resolved by adding the support ring into the launching tube.By increasing charging masses,enhancing flame spread velocities or cutting down particle sizes of propellants,the bullet initial velocity can be remarkably enhanced.The sound level of micropores smokeless propellant charging（MSPC）is similar to black powder charging（BPC）.The muzzle flash illuminance level and the relative smog concentration of MSPC is lower than BPC.It ＇ s basically feasible that the micropores smokeless propellant for firework can be substituted for black powder on the ground level fireworks.
