On-wing washing for civil aviation engine is an important approach to improve the Exhaust
Gas Temperature Margin (EGTM), and to reduce the fuel consumption as well as the …

Studies have shown that online compressor washing of gas turbine engines slows down the
rate of fouling deterioration during operation. However, for most operators, there is a …

Purpose The purpose of this paper is to present a quantitative fault diagnostic technique for
a two-shaft gas turbine engine applications. Design/methodology/approach Nested artificial …

Abstract The prediction of Exhaust Gas Temperature Margin (EGTM) after washing aero-
engines can provide a theoretical basis for airlines not only to evaluate the energy-saving …

Aircraft operators find themselves in an environment in which the economic and ecological
pressure on companies is constantly increasing. To address this, significant improvements …

Three distribution forms of uniform fouling thickness, leading edge fouling thickness and
trailing edge fouling thickness were established for the typical thickness distribution of …

The literature contains many studies relating gas turbine axial compressor degradation with
impurities entering the inlet flow path. The collision and adhering of these impurities onto …

This paper focuses on finding a lasting solution to the reason why offline compressor
washing of unit 13 at Geregu Power plc in Ajaokuta does not restore power output lost due …

Le turbine a gas sono una delle pricipali fonti di energia, sia per applicazioni aeronautiche
che terrestri. Proprio per questa ragione, esse sono spesso costrette ad operare in ambienti …

Solid particles ingestion can deteriorate performance and stability of gas turbines through
the build-up of deposits on the aerofoils. In some cases, the effect is sufficient to require an …
