Finding the Best Rotational Speed Affecting the Stresses Analysis for Gas Turbine Blades Subjected to Centrifugal Forces

By the current research the first stage rotor blade of a two-stage gas turbine has been analyzed and by using several different speeds ranging from 7500 to 11500, stress analysis and finding the best speed and less stress. The finite element method (FEM) has now become a very important agent of engineering analysis. Its truth is reflected in its popularity between engineers and designers pertinence to nearly all the engineering majors.AUTOCAD software is used to model it. analysis is performed by ANSYS14.5 software. The ANSYS program was used14.5 to find the stresses raised on the gas turbine blades by cutting the blade into 11 slides and a distance between one slice and another(9.536mm), and then it was subjected to five different speeds and calculated the stress values and the values confirmed that the best speed with the least effective stress is 7500r.p.m
