The aim of this investigation is to describe a way of setting up a fuzzy-logic process to achieve diagnoses, based on gas-path measurements, for modern military turbofan engines. Each engine's gas-path components' faults are quantified, taking into account measurement noise, through a non-linear...

Despite inflating unit-fuel costs, the long-term prospects for the aircraft industry remain buoyant. Nevertheless reducing direct operating-costs is crucial to ensure competitive advantages for airlines and manufacturers, and so effective advanced engine-condition monitoring methodologies are...
