摘要
激光冲击起爆炸药系统具有时间控制精确,快速响应,抗电磁干扰的特点,满足现代火工品的应用需求,但是由于激光传输效率和利用效率较低,目前难以实现真正的实用化和工程化。分析了激光驱动飞片起爆炸药的临界飞片速度的估算方法,提出需要提高系统能量利用率的必要性,总结了利用光纤传能和激光驱动复合飞片提高系统能量利用率这两项关键技术的研究进展。指出,选用适宜的光纤,改善光纤抗损伤能力,设计合理的光纤传输光路,优化激光参数,改进复合靶膜结构,合理选取复合靶膜各层厚度等是实现激光冲击片雷管小型化、实用化、工程化必须解决的问题。
Laser-driven miniflyer system is characterized by high precision control in time, prompt initiation, anti EMI and reliable initiation, which meets the requirements of modern initiators. Due to low transmission and utilization efficiency of laser, it＇sdiffi- cult to apply this system in practice. The velocity of laser-driven flyer in explosive detonation is predicted and the necessity of im- proving efficiency is put forward. Two key technologies in improving energy efficiency are highlighted and reviewed, including transmission through fibers and coupling with multi-flyer. It must be solved for realizing miniaturized, practical and engineered initiation system of laser-driven flyer to select proper optic fiber, enhance fiber damage resistance, design proper fiber transmission channel, optimize laser parameters, improve structure of multi-flyer, and determine the thickness of each layer.
