| 摘 要： | 采用DTA、TGA、定容燃烧试验和电缆桥塞地面试验等方法,研究了NLG型桥塞火药的耐热性及其常、高温燃烧稳定性。结果表明：NLG型桥塞火药的耐热温度在250℃以上;120℃高温定容燃烧时,NLG型桥塞装药的燃气生成速率在28.0MPa压力以上时快于常温,燃烧稳定;在电缆桥塞坐封工具中变容燃烧时,NLG型桥塞装药燃烧稳定,压力上升曲线与常温时基本一致,最大压力平均值比常温高出2.5MPa。

| Abstract: | Heat-resistant ability and burning stability at both high temperature and room temperature of NLG bridge-plug propellant were researched by DTA method,TGA method,closed-vessel experiments and bridge-plug equipment experiment.The results show that the heat-resistant temperature of NLG bridge-plug propellant is higher than 250℃.When burning at high temperature 120℃ and constant volume,the gas-generating rate of the propellant charge is more than that at room temperature at the pressure of more than 28.0MPa,with stable burning.NLG bridge-plug propellant charge also can burn steadily in the bridge-plug equipment,with almost same pressure ascended curve and the average maximum pressure 2.5MPa more than that as that of room temperature. |
