Abstract: A mesh-deformation-based method was provided in transferring structural displacements to aerodynamics meshes for multidisciplinary optimization of turbine blades.The method focuses on disturbing interior nodes of aerodynamics meshes to keep mesh-quality for the deflected blades.The nodes was disturbed as if they are in a deformed solid under displacement loads.This solid represented the interrelationship of nodes of the aerodynamics meshes.Adisplacement transfer of a turbine blade was provided.The results indicate that the mesh-deformation-based method work well for the displacement transfer.
