Model-Based Fault Diagnosis for Turboshaft Engines [PDF]
IFAC Proceedings Volumes, 1997 Tests are described which, when used to augment the existing periodic maintenance and pre-flight checks of T700 engines, can greatly improve the chances of uncovering a problem compared to the current practice. These test signals can be used to expose and differentiate between faults in various components by comparing the responses of particular engine
