A laser-driven mini-flyer priming system has been a primary focus for research into advanced initiators in recent years. Due to the low transmission rates and efficieny in the utilization of lasers, it is difficult to apply such a system in practice. Improving the flyer structure’s technology is a key to increasing energy efficiency. We calculate and design the thickness of each layers in the composite flyer plates, then the composite flyers with different parameters are prepared using magnetron sputtering. Taking advantage of a photonic doppler velocimetry (PDV) high-speed testing system, the accelerating processes of flyers with different parameters are analyzed. An experimental comparison is made on HNS-IV donation between laser-driven single-layer aluminium flyer and composite flyer
