ABSTRACT:
An improved containment casing for use with turbomachinery, such as turbofan engines. The containment casing is provided with a ballistic barrier composed of ceramic composite tiles which promotes the ability of the containment casing to withstand an impact from a fan blade which is released within the casing. The barrier is sufficiently hard so as to resist the cutting action of the fan blade, as well as to dull the edge of the fan blade so as to minimize subsequent damage to the containment casing and engine. The barrier serves to distribute the impact of the fan blade, so as to reduce the likelihood of piercing or severing the containment casing.
