Abstract

The shape of the particles in ground simulations of space debris is mostly assumed as spherical particles. However, the number of flat particles in space debris is much higher than of spherical ones. Therefore, flat-shaped particles pose more danger to orbiting crafts. This paper describes a study that employs the laser-driven flyer technique to produce flat-shaped projectiles of different aspect ratio to impact on quartz glass (usually used as window in spacecraft) and studies the influence of the projectile boundary geometries on damage morphologies. The results show that the impact craters due to spherical particles and to flat ones are similar in shape but differ in depth of penetration and scatter. The equation for spherical debris was modified to describe the relationship between diameters of the crater and the flat projectile.
