Abstract
A Gas turbine is a mechanical device that extracts thermal energy from pressurized steam, and converts it into rotary motion. A system of angled and shaped blades arranged on a rotor through which steam is passed to generate rotational energy. The blades are designed in such a way as to produce maximum rotational energy by directing the flow of the stem along its surface. The blades are made at specific angles in order to incorporate the net flow of steam over it in its favor. The blades may be of stationary or fixed and rotary or moving or types. The aim of the project to design a turbine blade using 3D modeling software Catia by using the CMM point data available. CMM data taken from coordinate measuring machine. In this project we are conducing structural and model analysis by applying the different pressures for different levels for different speeds. By conducting above analysis we are finding stresses developing on blade and mode shape of the blade. Also we are plotting graph for all results. In our project we are also conducting thermal analysis for finding temperature distributing on blade. Thermal analysis, to verify the thermal characteristics of the blade is also done by applying temperature. Structural and thermal analyses are done in ANSYS. CATIA is the standard in 3D product design, featuring industry-leading productivity tools that promote best practices in design. ANSYS is general-purpose finite element analysis (FEA) software package. Finite Element Analysis is a numerical method of deconstructing a complex system into very small pieces ( of user-designated size) called elements.
