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...

The aim of this investigation is to be able to diagnose gas-path faults in gas turbines by minimising the differences between the observed and simulated data for the engine's behaviour. The simulated data are generated using a known set of faults as the input to the engine-behaviour aero-thermo...
