Abstract: In order to avoid penetration of the housing (38) of a gas turbine (10) in the event of burst failure, the gas turbine (10) includes a containment ring system (32). The gas turbine (10) is of the type which includes a rotor (12) having a turbine wheel (14) with blades (16) and a nozzle (18) outwardly of the turbine blades (16). The nozzle (18) is adapted to direct hot gases at the turbine blades (16) to cause rotation of the rotor (12). The gas turbine (10) is also of the type having an annular combustor (20) about the rotor (12) along with an outlet (22) to the nozzle (18). The annular combustor (20) is defined by spaced inner and outer walls (24 and 26) connected by a generally radially extending wall (28). With this arrangement, the gas turbine (10) utilizes a radial turbine containment ring system (32) which has a first containment ring (34) outwardly of the rotor (12) and the nozzle (18) and a second containment ring (36) at least partially about the rotor (12) outwardly of the turbine blades (16) to deflect fragments toward the first containment ring (34) while dissipating fragment energy in the event of burst failure.
