Design and Analysis of Gas Turbine Blade
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
In the present work the first stage rotor blade of a two stage gas turbine has been analysed for static structural, steady state thermal, modal and high cycle fatigue using ANSYS 17. An attempt has been made to investigate the effect of temperature and induced stresses on the turbine blade. A structural analysis has been carried out to investigate the stresses and displacements of the turbine blade which is been develop due to the coupling effect of thermal and centrifugal loads. A steady state thermal analysis has been carried out to investigate the direction of the temperature flow which is been develops due to the thermal loading. An attempt is also made to suggest the best material for a turbine blade by comparing the results obtained for three different materials such as Titanium Ti 6Al 4V, INCONEL 625 and N-155 that has been considered for the analysis. The turbine blade along with the fir tree joint is considered for the static structural, fatigue, thermal and modal analysis. The blade is modelled with CATIA V5. The geometric model of the blade profile is generated with splines and extruded to get a solid model.
