摘要:
PETN、RDX和造粒RDX 可作为飞片雷管激发药。为了研究这3种激发药的燃烧性能,制备了不同配比的造粒RDX,并采用50 mL密闭爆发器测试了3种激发药定容条件下的燃烧速度和峰值压力。结果表明:相同点火条件下,PETN的燃烧速度大于RDX;相同质量的RDX燃烧产生的峰值压力大于PETN;随着KClO4质量分数的增加,造粒RDX的燃烧速度和峰值压力均呈现先增大后减小的趋势;当KClO4质量分数为30%~40%时,造粒RDX燃烧性能最佳。
Abstract:
To study the combustion performance of excitation powders, including PETN, RDX and granulated RDX prepared with different formulations, closed bomb was used to measure burning rates and peak pressures of powders under constant volume condition. Results indicate that under the identical ignition, the combustion velocity of PETN is larger than that of RDX while RDX generates a larger peak pressure than the same amount of PETN can do. The velocity and pressure of granulated RDX initially increase and then decrease with the increased amount of KClO4 . The granulated RDX works best at a KClO4 mass fraction range from 30% to 40%.
