ABSTRACT

A gas turbine is a device designed to convert the heat energy of fuel into useful work such as mechanical shaft power. Turbine Blades are the most important components in a gas turbine power plant. The blades are responsible for extracting energy from the high temperature, high pressure gas produced by the combustor. To survive in high temperature, high pressure gas environment, turbine blades often use exotic materials like super alloys

The turbine blades are mainly affected due to gas forces namely tangential, axial forces. Also the temperature has significant effect on the blades. This paper deals with such phenomenon using a finite element model in Ansys.

In this paper different NI-CR alloy of High Pressure rotor blade of the gas turbine has been analyzed using finite element analysis for the gas forces namely tangential, axial forces at different operating temperature and modal analysis. The High Pressure rotor blade of the gas turbine is created in CATIA V5 R19 software. This model has been analyzed using ANSYS for the gas forces and modal analysis. The gas forces namely tangential, axial were determined by constructing velocity triangles at inlet and exist of rotor blades. By the result of analysis we can optimize the High Pressure gas turbine rotor blade.  

Keywords: Gas turbine blade, Operating temperature, Structural Analysis, Finite Element Analysis
