Laser-driven flyer technology has the advantages of high flying speed, low cost and simple device that can not be replaced by the traditional high-voltage loading technology.With the development of laser technology, the use of high-power laser pulse to fly high-speed flyer is more and more The paper introduces the laser-driven high-speed flying test carried out on SG-Ⅲ prototype device.The experiment and research on several different ways of accelerating fly-fly are designed and carried out by using nanosecond short pulse and nanosecond shaping long pulse, Successfully obtained 10 km · s ~ (-1) solid aluminum flyer and 50 km · s -1 ultra-high speed composite metal flyer, and the fly-sheet has good planarity and integrity of the experiment The physical design, technical approaches and data results are analyzed in a comprehensive way, which provides a new idea for further experimental research on laser-driven high-speed flyer. At the same time, it also proves that the SG-III prototype device has the advantages in laser-driven high-speed flyer experimental research huge potential.
