Abstract
A casing for a gas turbine engine, including: an inner surface portion; a pair of wall portions extending radially outward from the inner surface portion; and a containment ring located between the pair of wall portions, the containment ring including an inner ring, an intermediate ring, and an outer ring, the intermediate ring being located between the inner ring and the outer ring, wherein the containment outer ring is mechanically decoupled from the pair of wall portions.
Claims14
A casing for a gas turbine engine, comprising:
- an inner surface portion;
- a pair of wall portions extending radially outward from the inner surface portion;
- and
- a containment ring located between the pair of wall portions, the containment ring including an inner ring, an intermediate ring, and an outer ring, the intermediate ring being located between the inner ring and the outer ring, wherein the outer ring is formed from a composite material or a metal and the outer ring is mechanically decoupled from the pair of wall portions such that deformation and ovalization of the outer ring due to forces at a point of impact will redistribute containment forces from the outer ring to the intermediate ring at a location opposite to the point of impact;
- wherein the outer ring has a pair of radially extending flange portions that are received by complimentary portions of the intermediate ring, each radially extending flange portion of the pair of radially extending flange portions installed axially between an axial extent of the intermediate ring and a wall portion of the pair of wall portions.

A gas turbine engine, comprising:
- a fan having a plurality of fan blades;
- a casing surrounding the plurality of fan blades, the casing comprising:
- an inner surface portion;
- a pair of wall portions extending radially outward from the inner surface portion;
- and
- a containment ring located between the pair of wall portions, the containment ring including an inner ring, an intermediate ring, and an outer ring, the intermediate ring being located between the inner ring and the outer ring, wherein the outer ring is formed from a composite material or a metal and the outer ring is mechanically decoupled from the pair of wall portions such that deformation and ovalization of the outer ring due to forces at a point of impact will redistribute containment forces from the outer ring to the intermediate ring at a location opposite to the point of impact;
- wherein the outer ring has a pair of radially extending flange portions that are received by complimentary portions of the intermediate ring, each radially extending flange portion of the pair of radially extending flange portions installed axially between an axial extent of the intermediate ring and a wall portion of the pair of wall portions.
