  • In multi-disciplinary design optimization(MDO) of turbine blades,the coupling data between aerodynamics and structural mechanics models must be transferred to consider the multi-disciplinary coupling property.Amesh-regeneration method was proposed to transfer displacement in this paper.Agroup of lines were added on blade surface,and the shape of blades was determined by the shape of these control lines.According to the displacement of blade structure,the position coordinate of the nodes of the lines was adjusted to modify the shape of the blade's control lines,thus achieving the displacement transfer towards geometric model of blade.By re-meshing,the CFDmesh of the deformed blade was generated.
