The blade elasticity can influence hydrodynamic and structural performance of the propeller. The elasticity of the propeller is considered in the hydrodynamic simulation based on the CFD/FEM fluid-structure interaction method. And the hydrodynamic results of the elastic are compared with the rigid. Which show that the accuracy of elastic hydrodynamic prediction improved significantly compared with the rigid. In addition, the hydrodynamic prediction considering the elasticity also shows the transient fluid flow considering the influence of blade vibration. The study indicates considering blade elasticity can significantly improve the accuracy of propeller hydrodynamic prediction, and the prediction of fluid pulsation and propeller response can be used to analyse the flow noise and structural vibration.
