| Abstract: | A procedure of multidisciplinary design optimization(MDO) was investigated for impellers.Disciplinaries,such as aerodynamics,structure design and solid mechanics were involved in the investigation.The mathematical model of impeller MDO was established,and software for MDO was developed.The proposed procedure was applied to the design of an impeller of an aeroengine,the stresses were reduced and the weight was lightened,which indicate that the procedure presented is efficient. |
