Feasibility Study on Small Particle Ablation Using a Free-Flight Range

Abstract

The feasibility of using a free-flight range to investigate the re-entry behavior of small spherical particles (400 to 700 microns diameter) was experimentally investigated. Using laser photography, information was obtained of shape changes of particles in flight. Under the conditions of the experiments, it is concluded that Al2O3 spheres fragment as a result of thermal stresses.
