Patent ID: 7008173

Claim:
A containment device for use in retaining debris material traveling radially outward in a rotary device, the containment device comprising: an outer ring extending generally circumferentially and defining an inner surface directed radially inward; and a plurality of energy absorption elements disposed on the inner surface of the outer ring, each absorption element extending radially inward and circumferentially such that each absorption element is configured to be plastically deformed radially outward by debris material impacting the absorption element, wherein each absorption element includes a base and a cap, the base extending in a generally radial direction between a first end connected to the inner surface of the outer ring and a second distal end, the cap being connected to the base and defining an angle therebetween, the cap of each absorption element extending between a first end and a second end, the second end of the base being connected to the cap between the first and second ends of the cap.
