DISK CRACK DETECTION AND PROGNOSIS USING NON CONTACT TIME OF ARRIVAL SENSORS

Abstract:

Early detection of cracks in engine rotors can prevent uncontained engine fractures. A detection system may also reduce maintenance costs by increasing the time between inspections and reducing the number of spares required. Currently, the only method to monitor engine rotor degradation is through periodic removal of the engine from service, disassembly, and inspection of each rotor. The objective of this study was to propagate a crack in a cyclic engine test and evaluate the ability of an ed...
