Fatigue Life Estimation of a Turbine Rotor Blisk by Finite Element Analysis
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 3
Abstract
A Small Gas Turbine (SGT) blisk is used for the power generation of a surveillance aircraft. So it is important to predict the fatigue life of a SGT blisk for the scheduling the maintenance and the safety of the aircraft. SGT blisk undergoes mainly four types of loadings. They are centrifugal, thermal, vibrational and aerodynamic loads. In the present work, the fatigue life of a SGT blisk is simulated with the help of an FEA package ANSYS. After defining an operating cycle of 2 hours; thermal, pressure and centrifugal loads are applied on the blisk and stress values at different time steps are extracted. From the analysis results it is observed that the blisk is operating in the elasto-plastic region. So a strain based approach is suitable for the estimation of Low Cycle Fatigue and the same is estimated using Smith Watson Topper mean stress correction theory.
