| Abstract | In this paper, the finite element analysis of an aero-engine turbine is carried out through fluid-thermalstructure coupling simulation. The stress diagrams of this turbine under aerodynamic, centrifugal and thermal loads individually were determined by fluid analysis, static structure analysis, and steady-state thermal analysis. The coupled flow-thermal-structure method was also used to determine the stress distribution of the multiple load fields. It is found that max stresses appear at the root of the turbine blade. And the thermal and centrifugal loads have a significant effect on the stress level of the turbine, while the aerodynamic load does not have a significant effect on the stress level of the turbine.
