炸药缓慢加热条件实验技术进展

Development of Slower Cook-off Test for Explosives

为降低炸药装药意外热刺激起爆后对武器平台、后勤系统和人员损伤的严重程度及概率,适应不敏感弹药发展过程中对炸药热危险性综合评定的需要,有针对性地分析了以美国为主的炸药和弹药装药慢烤燃实验相关文献、STANAG 4382《北约弹药缓慢加热测试标准》调查报告以及西安近代化学研究所开展的密闭系统的模拟弹慢速烤燃实验研究成果。分析结果发现,尚需解决的问题为3.3℃/h温升速率条件起源未知,小型模型实验技术是目前开展的重点,可视化/量化反应状态的实验技术及仿真预测试验反应剧烈程度的模型研究是发展重点,试验反应剧烈性抑制技术研究是未来的发展趋势。

To reduce the damage severity and probability to the weapon platform,logistics system and personnel in accidental thermal stimulation of explosive and to adapt to the need for comprehensive assessment on heat hazard of explosive during the development of insensitive ammunition,this paper focused on the analysis of US based literatures about slow cook-off,STANAG 4382(NATO ammunition slow cook-off test)investigation report,and research results of slow cook-off of Xi′an Modern Chemistry Research Institute.Analysis results show that the origin of 3.3℃/h temperature rise rate is unknown,the small model test is a main focus in the development of cook-off,the experimental technology of visualizing or quantifying the reaction state and the simulation prediction study on reaction severity are the developing priority,the suppression technology study of reaction violence is a developing trend.
