摘要:为实现战斗部毁伤效能精准调控与工程爆破的定向控制，设计了一种基于电子安全与解除保险装置（ESAD）的集成化直列式多点同步起爆系统。通过组建测试平台，系统研究了6通道爆炸箔同步/延时起爆特性。采用多通道光子多普勒测速技术（MPDV）实时获取飞片运动轨迹，结合钢凹法测试了各起爆点的输出性能。结果表明：随着电压的升高，多点起爆同步性差异减小；集成化直列式多点起爆系统可以实现多路延时起爆；6路飞片离开加速膛口时的平均速度为4 143 m·s-1，速度偏差为2.6%，时间同步性极差为7 ns；钢凹深度分布在0.56~0.64 mm。验证了集成化直列式多点起爆模式的可行性。
Abstract:To address the requirements of precise damage control in advanced warheads and directional blasting in civil engineering, an integrated in-line multi-point synchronous detonation system based on electronic safety and arming device (ESAD) was developed. A test platform was established to investigate the synchronous/delayed initiation characteristics of six-channel exploding foil initiators (EFIs). The multiplexed photon Doppler velocimetry (MPDV) was employed to capture real-time flyer kinematics, complemented by steel dent tests for comprehensive output evaluation. The results show that: as the voltage increases, the difference in multi-point detonation synchronization decreases; the integrated in-line multi-point detonation system can achieve multi-channel delayed detonation; the average velocity of the six-channel flyer as leaving the acceleration chamber is 4 143 m·s-1, with a velocity deviation of 2.6% and a maximum time synchronization difference of 7 ns; the depth distribution of the steel concave is between 0.56 mm and 0.64 mm. The feasibility of the integrated in-line multi-point detonation mode has been verified.
