Gaz Türbinli Uçak Motorlarının Termodinamik Modellenmesi

Abstract

Bu çalışmada, uçak motorlarında kullanılmakta olan bir gaz türbinli motorun termodinamik bağıntılar yardımıyla modellenmesi ve irdelenmesinde kullanılacak yöntem açıklanmıştır. Gaz türbinli motor, bileşenlere ayrılmış ve her bir bileşen termodinamiğin birinci ve ikinci yasalarıyla değerlendirilmiştir. Bu çalışmada ortaya konulan yöntem; ileride yapılabilecek turbojet, turboprop ve turbofan tipi gaz türbinli uçak motorlarının termodinamik analiz çalışmalarına temel oluşturacak ve ulusal literatüre kazandırılmış olacaktır.

Thermodynamic Modeling of Gas Turbine Aero-Engines

Abstract

In this study, a methodology for thermodynamic modeling and assessment of gas turbine engines operating on aircrafts is introduced. Gas turbine engine is analyzed for components separately and each component is evaluated on the basis of first and second laws of thermodynamics. Methodology which is expressed in this paper can provide a basis for thermodynamic analysis of turbojet, turboprop and turbofan engines in the future. On the other hand, methodology for thermodynamic evaluation of gas turbine aero-engines is added to national literature by this study. For better understanding of the methodology, a simple gas turbine engine assessed; exergy efficiencies of compressor, combustion chamber and turbine are found to be 89.72%, 70.85% and 93.01% respectively.
