Abstract
A projectile is provided for simulating multiple sequential ballistic impacts. The projectile has a plurality of relatively dense loading layers spaced along the firing direction of the projectile. Each pair of nearest-neighbor loading layers is separated by a less dense support element which maintains the spacing of the loading layers. The projectile may be suitable for simulating bird slurry impacts on stator vanes of an aero gas turbine engine.
