Crack Growth-Based Predictive Methodology for the Maintenance of the Structural Integrity of Repaired and Nonrepaired Aging Engine Stationary Components

Abstract

This report contains the description and results of work conducted by General Electric Aircraft Engines (GEAE) between October 1994 and April 1997 under the Federal Aviation Administration (FAA) contract to study aging engine issues relative to stationary components. Specifically, the FAA's goal was to develop "Crack Growth-Based Predictive Methodologies for the Maintenance of the Structural Integrity of Repaired and Nonrepaired Aging Engine Stationary Components." GEAE's project in support of this goal was to study specific components, combustion casings, and compressor rear frames in service on older GEAE engines to determine if periodic inspections are warranted and to develop the tools necessary to conduct effective inspections should the data support a proactive need. The project was originally scheduled to cover a 5-year period but was prematurely curtailed due to funding priorities. A detail description of the planned work scope along with results for that portion of the work that was completed are reported herein.
