ABSTRACT:
A cutter ring operable to sever the blades of a turbine wheel in a gas turbine engine upon failure of a thrust bearing carrying the wheel in the turbine. Severance occurs while the blades are within the confines of a containment ring to prevent fragments from being ejected out of the turbine housing. The cutter also presents a friction pad of high heat absorption characteristics for reducing maximum temperature developed in the engine upon bearing failure.
