An investigation was made of the use of cubes as fragment-simulators for armor evaluation and testing. One-quarter inch steel cubes were launched from a rifled barrel in an attempt to induce stability through spin stabilization. Specially molded lexan sabots were used to launch the cubes in the three predominant orientations: flat, edge, and point. The success rate of impact orientation predictability was high enough to warrant further consideration of cubes as fragment simulators. V50 ballistic limits were determined for four armor materials under flat, edge, and point impacts. Drag coefficients were determined for the three predominant orientations over the range of Mach numbers 0.5 to 3.5 and found to be generally higher than those previously measured by investigators who assumed cubes tumbled in flight.
