High energy containment device and turbine with same

A turbine with a containment device for containing debris material, the turbine comprising:

• a rotatable turbine rotor configured to rotate about an axis of rotation;
• at least one turbine blade connecting to the turbine rotor and configured to rotate about the axis of rotation with the turbine rotor;
• an outer ring extending circumferentially around the turbine rotor and at least one blade, the outer ring 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.

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, and the cap of each absorption element being thicker than the base of the respective absorption element.
