Abstract
Broken remnants of turbine engine rotor thru-bolt/nut interfaces are enveloped in a housing that is coupled to the rotor, so that the remnant does not migrate to other portions of the engine. In exemplary embodiments the housing directly mates with and engages the thru-bolt stud male threaded portion that projects outwardly from the nut, such as by a female threaded sleeve that is engaged with the male threads. The sleeve is in turn coupled to and/or supported by the rest of the housing. Some housing embodiments surround one or more of the threaded stud/nut interfaces. Housing embodiments of the invention are installed in situ without removing the rotor structure from the engine.
