| 摘 要： | 从粉尘点火模式探讨了高压水射流作用下复合推进剂的点火机理.采用改进的哈特曼管粉尘爆炸装置,进行了高氯酸铵/铝粉/二茂铁(AP/Al/ferrocene)混合体系粉尘爆炸下限质量浓度的实验研究,分析了混合体系粉尘爆炸的过程,研究了组分、环境温度、湿度对爆炸下限质量浓度的影响.结果表明,随着湿度的增加,粉尘体系爆炸下限质量浓度升高;而随着温度的增加,粉尘体系爆炸下限质量浓度则降低;此外,高氯酸铵和二茂铁的质量分数是影响混合体系爆炸下限质量浓度的敏感因素.

| Abstract: | In order to investigate the ignition mechanism of composite solid propellant under waterjet high pressure from the dust ignition mode perspective, the modified Hartman bomb device was used to study experimentally the minimum explosive mass concentration of AP/Al/ferrocene mixed system. Processes of dust explosion of the typical composite propellant were discussed. Effects of components, temperature and humidity on the minimum explosive mass concentration were investigated. Results show that the minimum explosive mass concentration increases with the increase of humidity, while it decreases with the increase of temperature. Also, the minimum explosive mass concentration of the mixed system is sensitive to the content of AP/ferrocene. |
