Design and Analysis of Gas Turbine Rotor Blade Using Finite Element Method

In the present work the first stage rotor blade of a two-stage gas turbine has been analyzed for structural, thermal using ANSYS 12 which is powerful Finite Element Software. In the process of getting the thermal stresses, the temperature distribution in the rotor blade has been evaluated using this software. From different materials titanium alloy, stainless steel alloy and Aluminum2024 alloy that has been considered for the purpose analysis. . The turbine blade along with the groove is considered for the static, thermal, modal analysis. The blade is modeled with the 3D-Solid Brick element. The geometric model of the blade profile is generated with splines and extruded to get a solid model. It is observed that the Maximum temperatures are observed at the blade tip section are linearly decreasing from the tip of the blade to the root of the blade section.
