heal.abstract	A procedure for the derivation of signatures for faults in the blades of a gas turbine is presented here. A variety of blade faults, corresponding to changes in the angle or spacing of one or more blades, are examined. A fluid dynamic simulation model is used to derive the unsteady pressure signals sensed by a stationary transducer for the cases of faulty blades. The blade fault signatures are derived by processing these signals using Fourier techniques. The features of blade fault signatures are studied. Finally, the possibilities they offer for the discrimination and identification of different possible blade faults are also examined. (C) 1998 Elsevier Science Ltd. All rights reserved.	en
