    摘要:

    从直列式点火系统构成、许用点火药硼-硝酸钾(Boron-Potassium Nitrate, BPN)的燃烧机理和新制备工艺以及国内外直列式爆炸箔点火相关标准三个方面,综述了直列式爆炸箔点火及相关技术的发展现状及应用。直列式点火系统有多功能多任务需求,因此作为控制模块的电子安全与解除安保装置呈现出编程寻址、多点协同的发展趋势,系统中各元件通过小型化和低能化减少系统装置所占空间。BPN通过新制备工艺进行组分粒度微纳米化,生成核壳结构,优化BPN燃烧性能、吸湿性和安定性等。总结并对比了国内外直列式爆炸箔点火相关标准。分析了直列式爆炸箔点火尚需研究的问题:冲击片直接点火BPN机理和BPN组分粒度对冲击点火感度的影响;BPN隔板点火的影响因素和规律;多种隔板点火结构的性能比较;BPN新制备方法及其对性能的优化。

    Abstract:

    The applications and development status of in-line exploding foil ignition and related technologies were reviewed, including the compositions of in-line exploding foil ignition system, the combustion mechanism and new preparation processes of an approved pyrotechnic-boron potassium nitrate (BPN), as well as the relevant standards of in-line exploding foil ignition at home and abroad. The in-line ignition system has the requirements of multi-function and multi-task. Therefore, the electronic safe and arm device as the control module of the ignition system device presents the development trend of programming addressing and multi-point coordination. The components of the in-line exploding foil ignition system become miniaturized and low energy consumption. The particle size of the components of BPN processed by the new preparation process was micronized and the core shell structure was generated. Hence, the combustion performance, moisture absorption and stability of BPN were optimized. The relevant standards of in-line exploding foil ignition at home and abroad were summarized and compared. The problems to be solved in the study of the in-line explosive foil ignition were analyzed, which includes the mechanism of direct ignition of BPN by slapper, the influence of BPN component particle size on impact ignition sensitivity, the influence factors and the laws of thru-bulkhead ignition of BPN, performance comparison of various thru-bulkhead ignition structures, and new preparation processes of BPN with its performance optimization.
