摘　　要：根据串联战斗部的使用要求,设计了毫秒级延时起爆装置替代引信起爆串联战斗部二级装药。毫秒级延时起爆装置使用硼/硝酸钾点火药实现毫秒级延期时间,利用钝黑-5炸药的燃烧转爆轰特性实现稳定的爆轰输出;该装置在攻坚弹、反飞机跑道弹药、爆破炸坑器等串联战斗部弹药中使用,可简化弹药结构设计,提高弹药作用可靠性;具有使用安全、作用可靠、性能稳定等特点。According to the using requirements of tandem warhead, a millisecond delay initiation device was designed in substitution for secondary charge of fuse action tandem warhead. Boron/potassium nitrate ignition composition was used in the millisecond delay initiation device to realize millisecond delay time. Because of the transition characteristics of defla- gration to detonation, desensitized RDX-5 explosive was used to realize stable detonation transfer capability. The device is used for tandem warhead such as hard structure ammunition, anti airstrip ammunition, blasting pit device and so on. It not only can simplify the structure design of ammunition, but also increase the reliability. And it has subsequent characteristics： the use of safe, reliable capability and stable performance.
