As hail ingestion tests are introduced into aero-engine certification procedures, there is an increasing need for an understanding of ice particle behaviour within an engine. In this paper, the possible effects that ingested ice may have on a turbofan engine are briefly discussed. The objective of this paper is to study the effect of target curvature on ice-ball (simulated hailstone) impact characteristics. The target curvature effect was studied on the concave side of two curved plates using the experimental techniques of patternator and still photography. The results are compared with those from a flat plate. The comparison shows that the curvature has a small effect on post-impact particle sizes, and significantly decelerates the movement of the particles after an impact.
