The present study investigates the aerodynamic separation of compact fragment clusters made up of spheres, cubes, and their combinations. This experimental analysis was conducted in the VKI Longshot hypersonic wind tunnel at Mach 14 flow conditions, using a dual camera free-flight testing methodology. The test articles are initially confined in a sabot, which separates into two pieces and exposes the models to the freestream upon the arrival of the flow. The aim of this research is to analyze how the shape of the objects influence the lateral separation velocities of the fragments. Testing clusters containing 11 and 36 objects enables drawing comparisons across varying population sizes and to juxtapose these findings with earlier literature results obtained under different geometrical configurations and freestream flow conditions.
