Experimental research on laser driven flyer and its application possibility in simulation of aerospace particles

GU Zhuo wei, SUN Cheng wei, LUO Li jun (Southwest institute of fluid physics, CAEP, Mianyang 621900, China)  
Aluminum flyer of 5.5μm thickness has been driven successfully by mini size KIDS laser in the energy range of 100~300mJ. The highest velocity of flyer has been up to 6.6km/s, and the relationship of flyer velocity and energy density has been obtained in experiments. The setup of experiments, measurement system, and experimental technique are introduced in detail, and analysis are given on experimental measurement system. The analysis to recovery samples show that the plane character, integrity character and repeated character of flyer are very good. The whole process is solved by using Gurney theory, and academic results are in good accord with experimental results. The analysis on the application possibility of laser driven flyer in simulating aerospace particles are done. The results show that laser driven flyer is very effective in simulating aerospace hypervelocity particles.
