[en] Free-flight testing in hypersonic wind tunnels has shown good capabilities for analyzing the flight of debris objects and scenarios for their separation.
The free-flight methodology implemented in the VKI Longshot facility was recently updated to facilitate the aerodynamic analysis of trajectories with six degrees of freedom.
The image processing algorithms are extended in the present work to carry out separation studies where the models can present overlapping configurations.
A dual-camera setup and the new routines proved suitable for tracking the motion of two spheres and cubes undergoing interactions.
The experimental results confirm that when non-spherical geometries interfere, the separation behavior is case-dependent and sensitive to the objects' orientation.
