The turbine blades are responsible for extracting energy from the high temperature gas produced by the combustor. Operating the gas turbine blade at high temperatures would provide better efficiency and maximum work output. In modern Aviation systems, turbine blades are made up of nickel based super alloys, generally N155 and Inconel alloys. Three widely used alloys namely N155, MAR M246 and Nimonic 80A are being selected for virtually constructing the blade and analysis purpose after going through several research works in relevant field. The present work is concerned with determining the best suited alloy among the three selected alloys mentioned above under a set of working parameters. An individual turbine blade has been modelled using SOLIDWORKS 2016. All the three materials are being virtually generated and the analysis work is carried out in the Finite Element Analysis software ANSYS Workbench V14.0. The results obtained from the analysis had been used to determine the total deformation, Von mises stress, Von mises strain and heat flux for each material under variable pressure and constant turbine inlet temperature. It is observed from the analysis that N155 has been found to exhibit better suitability and characteristics.
