摘要: 文中结合聚能战斗部所用引信对传爆序列的实际需求, 设计了一种适用于聚能战斗部直列式引信用的传爆序列, 其初级火工元件选用冲击片雷管, 爆炸网络采用一点输入、六点输出形式的同步起爆网络, 六点输出同步性极限偏差在200 ns以内。通过传爆序列起爆、传爆以及隔爆能量匹配性设计及试验, 验证了传爆序列各火工元件起爆、传爆匹配性良好, 在增强对爆炸网络施主药柱隔爆措施的情况下, 施主药柱不会直接起爆战斗部主装药, 由爆炸网络起爆聚能战斗部主装药, 爆炸能量能够按照预定的路径有控制地传递, 确保了爆炸网络正常发挥作用。Abstract: A detonation train suitable for shaped-charge warhead direct-line fuze is designed according to its actual demand. Impact detonator is used for the primary pyrotechnic components. The explosion network adopts synchronous initiation network in the form of ‘one point input and six-point output’, and the synchronization limit deviation of the six-point output is within 200 ns. Through design and test of the energy matching in detonation train initiation, explosion spreading and explosion suppression, it is proved that all components in detonation train have good energy matching in the initiation and explosion spreading phases. In the case of enhancing explosion suppression for explosion network donor grainl, the donor grainl does not directly initiate the main charge in warhead, and the explosive energy will transfer along the predetermined path in a controlled manner to ensure that the explosion network works properly and the main charge in the shaped-charge warhead is initiated by the explosion network.
