Ultra-high Speed Launch of Laser Driven Pellet

In this paper, by using a combination of theoretical simulation and experiment, the radiant fluid program HYADES was used to predict the flight speed of the target by theoretical simulation firstly. And the ultrahigh speed launch experiment of laser driven pellets was carried out on the SG Ⅲ prototype. The experimental results of accelerating aluminum balls with diameter of 200 μm to 44 km/s were obtained. In addition, the impact test of the highspeed aluminum ball and the protective material was completed, and the protective effect of the material was verified by the impact shape. This research is of great significance in simulating the impact and protection of space debris from orbiting spacecraft.
