Quantifying the Economic Benefits of Using Erosion Protective Coatings in a Low-Pressure Compressor (Aero-Engine): A Case Study Evaluation

Gas turbine engines (GTEs) frequently operate in desert environments where the main components are exposed to erosive media such as sand and dust. In these circumstances, a crucial problem, particularly with compressor blades, is solid particle erosion (SPE). Positioned front of GTE, compressors suffer most from SPE terms inflicting damage on hardware decreasing GTE’s working life increasing fuel consumption, energy losses, efficiency losses. Results obtained Turbomatch, an in-house performance tool, showed that degraded can experience increased entry temperature (TET) specific consumption (SFC), which leads significant increase operating, maintenance component replacement costs, addition costs. Fitting protective coatings (EPCs) conventional approach reduce blades aeroengines. Titanium nitride (TiN), applied via physical vapour deposition (PVD) techniques, often used extend conditions. This paper reports outcomes cost benefit analysis (CBA) whether applying EPC booster aeroengine economically beneficial. The case study takes into account available potential market, all technical data public domain regarding research engine. To identify economic consequences employing over compressor, CBA was carried out by investigating consequent benefits results indicate under certain conditions application be profitable.
