Performance-analysis-based gas turbine diagnostics: a review.

Abstract

Gas 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
