摘要:为提升传统隔板起爆器的安全性及电磁环境适应性，设计了一种不含起爆药的爆炸箔隔板点火器，进行了6种传火序列的传火性能验证试验，确定了2种优化的传火序列装药设计方案。针对优化的传火序列，进行了5种隔板厚度的传火性能裕度试验。结果表明：当传火序列施主端装药为JH-14、隔板厚度为2mm、受主端装药为经过细化处理的JO-9C时，试验后隔板结构完好，输出装药B/KNO3被点燃，并且可以保证设计裕度。研究结果可作为工程设计的参考依据。
Abstract:In order to improve the safety and electromagnetic environment adaptability of traditional through-bulkhead initiator, an explosive foil through-bulkhead igniter without primary explosive was designed. The fire transfer performance verification tests of six fire transfer sequences were carried out, and two optimized charge design schemes of fire transfer sequences were determined. According to the optimized fire transfer sequence, the fire transfer performance margin tests of five bulkhead thicknesses were carried out. The results show that when the donor end charge of the fire transfer sequence is JH-14, the thickness of the bulkhead is 2mm, and the acceptor end charge is refined JO-9C, the bulkhead structure is intact after the test, the output charge B/KNO3 is ignited, and the design margin can be guaranteed. The study results can be used as a reference for engineering design.
