Abstract
This study was undertaken to identify the Canadian Forces' experience with high cycle fatigue failures in aeroengines. The three specific objectives were to determine any trends based on an analysis of historical data, provide some direction to research and development efforts that would lead to a better understanding of HCF failures, and lastly, to offer comment on areas of collaboration amongst The Technical Cooperation Program partners. The two sources of information consulted were the flight safety data held in the aircraft accident and incident information system (ACAIRS) and the pool of failure analysis reports held at the Quality Engineering and Testing Establishment in Hull, Quebec. In this study, it was found that whenever an HCF problem has occurred, the CF had it addressed and resolved largely through very high hidden cost as they usually affect the majority, if not all, the engine fleet. A technology program to control the costs and risks associated with HCF failures is possible, and would be focussed on F404 engine materials. The program elements proposed would build on the current dynamic response project under the 3.g.a DND/NRC-IAR collaborative program in aeropropulsion.
