Abstract
A blade containment system for turbomachinery includes an annular casing having an interior surface with an abrasive surface texture that is capable of dulling sharp comers and edges of impacting fan blades so as to reduce the ability of the fan blade to pierce the containment casing. The textured surface can be produced by either a plurality of protuberances attached thereto or a plurality of sharp dimples formed therein. The protuberances can be in the form of sawtooth steps, sharp spikes or pieces of a hard material impregnated in the textured surface. In one preferred embodiment, the textured surface is formed on a plurality of tiles secured to the interior surface of the containment casing.
