Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, Volume 216, Number 5 (September 1, 2002), pp. 363-377.0957-6509http://dx.doi.org/10.1243/095765002320877856http://dspace.lib.cranfield.ac.uk/handle/1826/1008Gas turbine diagnostics has a history almost as long as gas turbine development itself. Early engine fault diagnosis was carried out based on manufacturer information supplied in a technical manual combined with maintenance experience. In the late 1960’s when Urban introduced Gas Path Analysis, gas turbine diagnostics made a big breakthrough. Since then different methods have been developed and used in both aero and industrial applications. Until now a substantial number of papers have been published in this area. This paper intends to give a comprehensive review of performance analysis based methods available thus far for gas turbine fault diagnosis on open literature.en-UKArticle
